PROSPECTUS SUPPLEMENT SUMMARY The following summary may not contain all the information that may be important to you. You should read this summary together with the more detailed information included elsewhere in this prospectus supplement and the accompanying prospectus. In addition, important information is incorporated by reference into the accompanying prospectus. Unless otherwise expressly stated or the context otherwise requires, the information in this prospectus supplement assumes that the underwriters do not exercise their option to purchase additional shares of Class C preferred stock to cover over-allotments. The Company We are a self-managed and self-administered REIT owning full-service hotel properties. Through our subsidiaries, we currently own 122 hotels, containing approximately 58,000 rooms located throughout the United States and in Toronto and Calgary, Canada. These hotels are generally operated under the Marriott, Ritz-Carlton, Four Seasons, Swissotel, Hyatt and Hilton brand names. These brands are among the most respected and widely recognized names in the lodging industry. We were formed as a Maryland corporation in 1998, under the name HMC Merger Corporation, as a wholly owned subsidiary of Host Marriott Corporation, a Delaware corporation, in connection with Host Marriott's efforts to reorganize its business operations to qualify as a REIT for federal income tax purposes. As part of this reorganization, which we refer to as the REIT conversion, on December 29, 1998 we merged with Host Marriott and changed our name to Host Marriott Corporation. As a result, we have succeeded to the hotel ownership business formerly conducted by Host Marriott, the Delaware corporation. We conduct our business as an umbrella partnership REIT, or UPREIT, through Host Marriott, L.P., a Delaware limited partnership, of which we are the sole general partner and in which we hold approximately 82% of the partnership interests. As used in this prospectus supplement, references to "we," "our," the "company" and "Host Marriott" and similar references are to Host Marriott Corporation, a Maryland corporation, and its consolidated subsidiaries from and after December 29, 1998 and to Host Marriott Corporation, a Delaware corporation, and its consolidated subsidiaries before December 29, 1998, unless otherwise expressly stated or the context otherwise requires. References to the "operating partnership" are to Host Marriott, L.P. Under the law in effect prior to 2001, a REIT was required to lease its hotels to unrelated third parties. As a result of REIT tax law changes under the specific provisions of the Work Incentives Improvement Act of 1999 relating to REITs (we refer to the provisions as the "REIT Modernization Act") that became effective January 1, 2001, a REIT now is permitted to lease its hotels to "taxable REIT subsidiaries," which are subsidiaries of the REIT that are subject to regular corporate tax. However, the hotels must be operated on behalf of the taxable REIT subsidiary by managers that are unrelated third parties. Accordingly, prior to 2001, we leased substantially all of our hotels to certain entities we refer to as the "lessees," which were principally subsidiaries of Crestline Capital Corporation. Effective January 1, 2001, a wholly owned subsidiary of the operating partnership that will elect to be treated as a taxable REIT subsidiary, HMT Lessee LLC, acquired direct or indirect ownership of all but one of the full-service hotel leasehold interests owned by the Crestline lessees through the transactions discussed further in this prospectus supplement. The lessees operate the hotels pursuant to management agreements with unaffiliated hotel managers, such as Marriott International, Inc., which are responsible for the day-to-day management of the hotels. However, we are responsible for, among other things, decisions with respect to sales and purchases of hotels, the financing of the hotels, the leasing of the hotels and capital expenditures for the hotels, although some matters relating to capital expenditures are addressed by the management agreements. Crestline and Marriott International are both publicly traded companies, separate from Host Marriott. Our principal executive offices are located at 10400 Fernwood Road, Bethesda, Maryland 20817-1109, and our telephone number is (301) 380-9000. S-4

The Offering Issuer................ Host Marriott Corporation Securities Offered.... 5,200,000 shares of 10% Class C Cumulative Redeemable Preferred Stock, par value $.01 per share. We may sell up to 780,000 additional shares of Class C preferred stock to the underwriters to cover over-allotments, if any. Maturity.............. The Class C preferred stock does not have any maturity date nor are we required to redeem the Class C preferred stock. Accordingly, the Class C preferred stock will remain outstanding unless we decide to redeem it. In addition, we are not required to set aside funds to redeem the Class C preferred stock. Dividends............. Investors will be entitled to receive cumulative cash dividends on the Class C preferred stock at a rate of 10% per year of the $25.00 per share liquidation preference (equivalent to $2.50 per year per share). Dividends on the Class C preferred stock will be payable quarterly in arrears on January 15, April 15, July 15 and October 15 of each year, commencing April 15, 2001. Dividends on the Class C preferred stock will be cumulative from the date of original issuance, which is expected to be March 27, 2001. Because the first dividend payment date is April 15, 2001, the dividend payable on each share of Class C preferred stock on that date will be less than the amount of a full quarterly dividend. Optional Redemption... We may not redeem the Class C preferred stock prior to March 27, 2006 except under limited circumstances intended to preserve our status as a real estate investment trust for federal income tax purposes and the operating partnership's status as a partnership for federal income tax purposes. On and after March 27, 2006 we may, at our option, redeem the Class C preferred stock, in whole or from time to time in part, for cash in the amount of $25.00 per share, plus accrued and unpaid dividends to, but not including, the date of redemption. Liquidation Preference............ If we liquidate, dissolve or wind up, holders of the Class C preferred stock will have the right to receive $25.00 per share, plus accrued and unpaid dividends to, but not including, the date of payment. Payment of this liquidation preference must be made before any payment is made to the holders of our common stock with respect to the distribution of assets upon our liquidation, dissolution or winding up. Ranking............... The Class C preferred stock will rank, with respect to the payment of dividends and the distribution of assets upon our liquidation, dissolution or winding up: (1) senior to our common stock and (2) on a parity with our 10% Class A Cumulative Redeemable Preferred Stock, par value $.01 per share and our 10% Class B Cumulative Redeemable Preferred Stock, par value $.01 per share. Voting Rights......... Holders of Class C preferred stock will generally have no voting rights. However, if we do not pay dividends on the Class C preferred stock for six or more quarterly dividend periods (whether or not consecutive), the holders S-5

of the Class C preferred stock, voting as a class with the holders of any other class or series of our capital stock which has similar voting rights, will be entitled to vote for the election of two additional directors to serve on our board of directors until we pay all dividends which we owe on the Class C preferred stock. In addition, the affirmative vote of the holders of at least two-thirds of the outstanding shares of Class C preferred stock is required for us to issue capital stock ranking senior to the Class C preferred stock or to amend our articles of incorporation in a manner that materially and adversely affects the Class C preferred stock. Listing............... The Class C preferred stock has been approved for listing on the New York Stock Exchange under the symbol "HMTPrC", subject to official notice of issuance. We expect that trading of the Class C preferred stock on the NYSE will commence within 30 days after initial delivery of the Class C preferred stock. Restrictions on Ownership and Transfer.............. The Class C preferred stock will be subject to certain restrictions on ownership and transfer intended to assist us in maintaining our status as a REIT for federal income tax purposes and the status of the operating partnership as a partnership for federal income tax purposes. In general, no person may own, or be deemed to own under the attribution rules of the Internal Revenue Code, more than 9.8% of the Class C preferred stock that is outstanding. A detailed description of these restrictions is contained in the accompanying prospectus under "Restrictions on Ownership and Transfer". Conversion............ The Class C preferred stock will not be convertible into or exchangeable for any other securities or property. Use of Proceeds....... We will contribute the net proceeds from the offering of the Class C preferred stock to the operating partnership in exchange for preferred partnership interests in the operating partnership which will have economic terms substantially similar to those of the Class C preferred stock. The operating partnership will use these net proceeds for general business purposes, which may include: . the repayment of indebtedness (including amounts outstanding under our bank credit facility); and . the acquisition or development of hotel properties. Risk Factors You should carefully consider the matters set forth under "Risk Factors" beginning on page S-13. S-6

Summary Historical and Pro Forma Financial Data In the following table we set forth summary historical consolidated financial data for us and our subsidiaries for the three fiscal years ended December 31, 1999 and for the thirty-six weeks ended September 8, 2000 (our first three quarters of 2000) and September 10, 1999 (our first three quarters of 1999). The summary historical consolidated financial data as of and for the three fiscal years ended December 31, 1999 have been derived from our audited financial statements. The summary historical consolidated financial data as of and for the first three quarters of 2000 and 1999 are unaudited but, in the opinion of management, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of such data. Interim results are not indicative of fiscal year performance because of the impact of seasonal and short term variations. Under the law in effect prior to 2001, in order to qualify as a REIT, we were restricted from operating hotels directly and, as part of the REIT conversion, we leased substantially all of our hotels to subsidiaries of Crestline Capital Corporation. Effective January 1, 2001, HMT Lessee, a wholly owned subsidiary of the operating partnership that will elect to be a taxable REIT subsidiary effective January 1, 2001, acquired direct or indirect ownership of the leasehold interests in 116 of our full-service hotel properties from Crestline. As a result of the acquisition of the Crestline leases, beginning with the first quarter of 2001 for the 116 of our hotels that are now leased by HMT Lessee, we will present on our consolidated statements of operations hotel-level revenues and expenses (e.g. room and food and beverage revenues and expenses and management fees) as well as owner expenses (e.g. property taxes, ground leases and insurance) rather than rental income, which was calculated based on hotel-level revenues and expenses. This is the way that we presented our consolidated statement of operations through 1998, prior to the REIT conversion. Six leases, including the one still held by Crestline, have not been purchased and therefore results of these hotels will continue to be reported as rental income. See "Recent Developments" for a description of the acquisition of the Crestline leases. The summary pro forma consolidated financial data set forth below reflect numerous transactions including: . the issuance of Class C preferred stock in this offering; . several hotel acquisitions and dispositions consummated by us and our subsidiaries and various financing transactions; . the conversion of 12.5 million units of the operating partnership for Host Marriott common stock described in "Recent Developments"; . the settlement of litigation described in "Recent Developments"; and . the purchase in January 2001 of leasehold interests in 116 of our hotels from Crestline. The summary pro forma statement of operations and other data reflects the foregoing transactions as if the transactions had been completed at the beginning of the periods presented. As discussed further in the "Pro Forma Financial Information", certain of these transactions occurred prior to September 8, 2000 and therefore were included in the September 8, 2000 historical balance sheet. Consequently, no pro forma adjustments to the pro forma balance sheet data are required for these transactions. Our pro forma statement of operations and other data presented below include only income from continuing operations and, therefore, they exclude the operations of the discontinued senior living business and the effect of extraordinary items. The summary pro forma financial data set forth below are unaudited, are based upon a number of assumptions and estimates and do not purport to be indicative of the operating results or financial position that we would have achieved had the transactions actually been consummated on the dates specified, nor do they purport to be indicative of our operating results or financial position for any future periods or dates. The summary historical and pro forma financial data should be read in conjunction with the audited and unaudited consolidated financial statements which we incorporate by reference into the accompanying prospectus and the "Pro Forma Financial Information" beginning on page S-24. For additional details concerning the transactions reflected in the pro forma financial data, investors should also carefully review the documents which we incorporate by reference. S-7

Accordingly, in 1998 we changed our fiscal year end to December 31 for both financial and tax reporting requirements. Previously, our fiscal year ended on the Friday nearest to December 31. As a result of this change, the results of operations for 15 hotels not managed by Marriott International were adjusted in 1998 to include 13 months of operations (December 1997 through December 1998) and therefore are not comparable to fiscal year 1997 which included 12 months of operations. The additional month of operations in 1998 increased our revenues by $44 million. (2) The historical financial data for fiscal years 1998 and 1997 reflect as discontinued operations our senior living business that we formerly conducted but disposed of in the spin-off of Crestline as part of the REIT conversion. We recorded income from the discontinued operations, net of taxes, of $6 million and $0 in fiscal years 1998 and 1997, respectively. (3) For 1999 and 1997 we incurred extraordinary gains of $15 million and $3 million, net of taxes, respectively. In 1998 we incurred an extraordinary loss of $148 million, net of taxes. (4) The 2000 pro forma statement of operations does not include a one-time non-recurring loss of $207 million on the acquisition of leases from Crestline and the corresponding deferred tax asset of $82 million. The 1999 pro forma and historical statements of operations include a $40 million non-recurring loss on the settlement of litigation for seven limited partnerships in which we were the general partner. (5) Historical revenue for the First Three Quarters 2000 and 1999 primarily represent lease income generated by our leases with Crestline. We deferred $366 million and $339 million, respectively, of contingent rent which is based on a percentage of hotel sales until certain annual thresholds have been met in accordance with Staff Accounting Bulletin 101. This percentage rent was recognized as income during the fourth quarter of 2000 and 1999, respectively, once the specified hotel sales thresholds had been achieved. Effective January 1, 2001, HMT Lessee acquired direct or indirect ownership of the leasehold interests in 116 of our full-service hotels from Crestline. Accordingly, the pro forma results of operations for the First Three Quarters 2000 have been adjusted to reflect the impact of the reversal of the contingent rent. The pro forma results of operations have also been adjusted to reflect this acquisition by presenting hotel-level revenues for these leasehold interests rather than rental income. Rental income on a pro forma basis includes the rental income for one hotel that is leased by Crestline and five hotels that are leased by other entities. See "Recent Developments" for a description of the acquisition of the leasehold interests from Crestline. (6) Total assets for fiscal year 1997 include $236 million, related to net investment in discontinued operations. (7) The ratio of earnings to combined fixed charges and preferred stock dividends is computed by dividing income from continuing operations before income taxes, fixed charges and preferred stock dividends by total fixed charges and preferred stock dividends. Fixed charges represent interest expense (including capitalized interest), amortization of debt issuance costs and the portion of rent expense that is deemed to represent interest. The deficiency of earnings to fixed charges is largely the result of the timing of recognition of contingent rental income which has been recognized in the fourth quarter of 2000 and 1999. S-8

RECENT DEVELOPMENTS Crestline Leasehold Interest Acquisition Effective as of January 1, 2001, HMT Lessee, a wholly owned subsidiary of the operating partnership that will elect to be treated as a taxable REIT subsidiary effective January 1, 2001, purchased from Crestline the equity interests in the lessees of 112 of our full-service hotels and the leasehold interests in four of our full-service hotels for $207 million in cash, including legal fees and transfer taxes. As a result of this transaction, we recorded a non-recurring loss of $207 million during the fourth quarter of 2000, reflecting the payment to Crestline and the payment of certain transaction expenses. We also recognized a deferred tax asset of $82 million because the assets acquired are recognized, for income tax purposes, as assets that will be amortized over the next seven years. As a result of the acquisition, HMT Lessee, through its subsidiaries, including the newly-acquired lessees, will replace Crestline as lessee and assume the obligations of Crestline under the management agreements with respect to those 116 full- service hotels. A subsidiary of Crestline will remain the lessee of one of our full-service properties. As a result of the acquisition of the leases from Crestline, any changes in earnings and cash flow levels at each specific hotel now leased by HMT Lessee will have a corresponding direct effect on our consolidated earnings and cash flows. Additionally, beginning with the first quarter of 2001, applicable accounting principles require us to present on our consolidated statement of operations hotel-level revenues and expenses (e.g., room and food and beverage revenues and expenses and management fees) as well as owner expenses (e.g. property taxes, ground leases and insurance) rather than rental income for the 116 hotels that are now leased by HMT Lessee. This is the way that we presented our consolidated statement of operations through 1998, prior to the REIT conversion. We believe that we will benefit from this new corporate structure by receiving the incremental earnings and cash flows previously paid to Crestline in its capacity as lessee. However, because Crestline used to guarantee a limited portion of the rental income, we no longer have this protection against a significant reduction in hotel revenues. For a discussion of the risks related to the acquisition of the leasehold interests from Crestline, see "Risk Factors--A reduction in hotel revenues would directly affect our earnings and cash flows". Courtyard Settlement and Tender Offers The operating partnership, Rockledge Hotel Properties, Inc., which is one of our non-controlled subsidiaries that will elect to be treated as a taxable REIT subsidiary effective January 1, 2001, and Marriott International, Inc. are parties to a settlement agreement with respect to lawsuits brought by and on behalf of the limited partners of Courtyard by Marriott Limited Partnership, Courtyard by Marriott II Limited Partnership and several other partnerships that own limited service hotels in which we act, or acted, as general partner. Pursuant to the settlement, in exchange for a general release of all claims, (1) the operating partnership and Rockledge Hotel Properties paid $31 million in the aggregate to the limited partners of four of the partnerships and (2) subsidiaries of CBM Joint Venture LLC, a joint venture between Rockledge Hotel Properties and Marriott International and their affiliates, acquired all of the outstanding units of limited partnership interest of Courtyard by Marriott Limited Partnership and Courtyard by Marriott II Limited Partnership pursuant to two tender offers that were completed on December 8, 2000. The operating partnership also owns a de minimis general partner interest in CBM Joint Venture. In connection with the settlement with Courtyard by Marriott Limited Partnership and Courtyard by Marriott Limited Partnership II, the operating partnership and Rockledge Hotel Properties made payments of approximately $79 million. As part of a separate settlement in connection with the same set of lawsuits, the operating partnership paid $2 million to the limited partners of another limited partnership in exchange for a general release of all claims. As a result of the acquisition by subsidiaries of CBM Joint Venture of the units of limited partnership interests in Courtyard by Marriott II Limited Partnership, CBM Joint Venture was required to offer to purchase the 10 3/4% Series B Senior Secured Notes due 2008 issued by Courtyard by Marriott II Limited Partnership at a purchase price equal to 101% of the principal amount of such notes. The purchase offer was undertaken by CBM Joint Venture on behalf of Courtyard by Marriott II Limited Partnership and was completed on January 26, 2001. Approximately S-9

$11.6 million of notes were purchased, representing approximately 9% of the outstanding notes. Rockledge Hotel Properties has approximately a 50% non- controlling interest in the CBM Joint Venture which owns 120 Courtyard by Marriott limited-service properties totalling 17,554 rooms. Credit Facility Borrowing We borrowed approximately $90 million under the revolving loan portion of our credit facility in the first quarter of 2001. We have used these funds for general corporate purposes as well as for the partial funding of our Crestline leasehold interest acquisition described above and the payment of certain tax obligations. As of February 2, 2001, there was $150 million outstanding under the term loan portion of the credit facility and $90 million outstanding under the revolving loan portion of the credit facility, with an additional $535 million available under the revolving portion of the credit facility, subject to its terms and conditions. Blackstone Sale On February 7, 2001, we issued to various entities affiliated with The Blackstone Group (the "Blackstone Entities") 12.5 million shares of our common stock upon their surrender of 12.5 million units of the operating partnership for redemption. This increased our ownership interest in the operating partnership from 78% to approximately 82%. The Blackstone Entities continue to own approximately 30.5 million units of the operating partnership, or a 11% minority interest in the operating partnership. In addition, the Blackstone Entities sold the 12.5 million shares for $12.45 per share in an underwritten public offering. We received no proceeds from the sale of these shares. The shares represented approximately 4.4% of the total number of shares of our common stock outstanding as of January 31, 2001, assuming the redemption of all outstanding units of the operating partnership not held by us for shares of common stock. 2000 Year End Results On March 6, 2001, we announced the results of operations for the fourth quarter and full year 2000. Our revenues reflect rental income from leases, which are calculated based on hotel-level sales of our leased hotels. As discussed above, beginning with the first quarter of 2001, we will report gross hotel-level sales as revenue for 116 of our hotels that are now leased by HMT Lessee. Six leases, including one still held by Crestline, have not been purchased and, therefore, results of these hotels will continue to be reported as rental income. Fourth quarter 2000 hotel-level sales were $1.44 billion, a 5.6% increase over fourth quarter 1999 hotel-level sales of $1.37 billion. Full year 2000 hotel-level sales were $4.51 billion, a 5.4% increase over full year 1999 hotel-level sales of $4.28 billion. The hotel-level sales were reported to us by our lessees. We reported fourth quarter 2000 rental income of $810 million versus $749 million for fourth quarter 1999 and full year 2000 rental income of $1.4 billion versus $1.3 billion for full year 1999. The reported rental income amounts include the recognition of contingent rent deferred under Commission regulations (Staff Accounting Bulletin 101) of $366 million and $339 million for the fourth quarter 2000 and 1999, respectively, because they were contingent upon achieving annual levels of hotel-level sales. Staff Accounting Bulletin 101 has no impact on the full year 2000 and 1999 results. These increases are primarily the result of strong increases in revenue per available room, or REVPAR, for both the quarter and the full year. REVPAR at our comparable properties (defined below) increased 6.7% and 6.6% for the quarter and the full year, respectively, primarily as a result of strong increases in room rates and slight increases in occupancy. The net income available to common shareholders for the fourth quarter 2000 decreased to $279 million compared to $320 million for the fourth quarter 1999. The net income available to common shareholders for full year 2000 decreased to $141 million compared to $216 million for full year 1999. The decreases in both fourth quarter and full year 2000 include a non-recurring loss, net of taxes, of $125 million recognized on the acquisition of leases from Crestline. Fourth quarter and full year 2000 results include $5 million and $20 million, respectively, in dividends on our preferred stock, which were issued during the second half of 1999. S-10

In connection with our announcement outlining the results of operations for the fourth quarter and full year 2000, we indicated that due to economic conditions, particularly in Atlanta and the Northeast, our REVPAR growth rate for the first two months of 2001 was considerably less than our REVPAR growth rate of 6.6% for comparable properties for full year 2000. The following table presents unaudited financial data regarding the results of fourth quarter and full year 2000 and 1999. We also present certain hotel- level operating data.

In the fourth quarter of 1999 we recorded a non-recurring loss on litigation settlement of $40 million. (2) In 2000 we recorded an extraordinary loss of approximately $2 million representing the write off of deferred financing costs and certain fees paid to our lender in connection with the renegotiation of our bank credit facility. An extraordinary loss of approximately $1 million representing the write-off of deferred financing fees occurred during the first quarter of 2000 when approximately .4 million shares of our convertible preferred securities were repurchased and subsequently retired. In 1999 we recorded an extraordinary gain of $14 million on the forgiveness of debt in the form of accrued incentive management fees in connection with the refinancing of the mortgage and renegotiation of the management agreement on the New York Marriott Marquis hotel. An extraordinary loss of $3 million representing the write-off of deferred financing fees occurred in July 1999 when the mortgage debt for eight properties, including the New York Marriott Marquis hotel, was refinanced. In connection with this refinancing, the interest rate swap agreements associated with some of the original debt were terminated and an extraordinary gain of $8 million was recognized. An extraordinary loss of $2 million representing the write-off of deferred financing fees occurred during the fourth quarter of 1999 when prepayments totaling $225 million were made to permanently reduce the outstanding balance of the term loan portion of the bank credit facility to $125 million. An extraordinary loss of $2 million representing the write-off of deferred financing fees occurred during the first quarter of 1999 when approximately 1.1 million shares of our convertible preferred securities were repurchased and subsequently retired.

(3) Basic earnings per common share is computed by dividing net income adjusted for dividends on preferred stock and gains on repurchases of convertible preferred securities by the weighted average number of shares of common stock outstanding. Diluted earnings per share is computed by dividing net income adjusted for dividends on preferred stock, gains on repurchases of convertible preferred securities, and potentially dilutive securities, by the weighted average number of shares of common stock outstanding plus other potentially dilutive securities. Dilutive securities may include shares granted under comprehensive stock plans and the convertible preferred securities. Dilutive securities also include those common and preferred operating partnership units issuable or outstanding that are held by minority partners which are assumed to be converted. (4) The ratio of earnings to combined fixed charges and preferred stock dividends is computed by dividing income from continuing operations before income taxes, fixed charges and preferred stock dividends by total fixed charges and preferred stock dividends. Fixed charges represent interest expense (including capitalized interest), amortization of debt issuance costs and the portion of rent expense that is deemed to represent interest. Calculation of the ratio for both years includes certain non-recurring losses. If these losses were not included ($207 million loss on acquisition of Crestline leases and $40 million loss on litigation settlement in 2000 and 1999, respectively) then the ratios would be 1.7x and 1.6x for 2000 and 1999, respectively. (5) The hotel operating statistics presented relate to comparable properties which consist of 118 properties owned, directly or indirectly, by us in each period covered, net of two properties where significant expansion at the hotels affected operations, one property that sustained substantial damage from a fire in the fourth quarter of 2000 and Tampa Waterside Marriott which opened in February 2000. Average daily rate represents the average rate charged daily for the periods presented for the comparable hotels. Average occupancy percentage represents the average number of rooms occupied for the periods presented for the comparable hotels on a percentage basis. REVPAR represents room revenue per available room, which measures daily room revenues generated on a per room basis, excluding food and beverage revenues or other ancillary revenues generated by the property. REVPAR growth for all our properties for the fourth quarter and full year 2000 over the prior periods was 5.2% and 5.4%, respectively. The reader should note that comparable properties as discussed in the remainder of this prospectus supplement are different as they address different reporting periods. S-12

RISK FACTORS The disclosure set forth below supersedes in its entirety the risks described in the section entitled "Risk Factors" in the accompanying prospectus. You should consider the following risks before deciding whether to purchase shares of Class C preferred stock. Risks of operation We do not control our hotel operations, and we are dependent on the managers of our hotels. Because federal income tax laws currently restrict REITs from deriving revenues directly from managing a hotel, we do not manage our hotels. Instead, we retain managers to manage our hotels pursuant to management agreements. Our income from the hotels may be adversely affected if the managers fail to provide quality services and amenities and competitive room rates at our hotels or fail to maintain the quality of the hotel brand names. We have very limited recourse if we believe that the hotel managers do not maximize the revenues from our hotels, which in turn would maximize our results of operations and cash flows on a consolidated basis. We do not control the assets held by the non-controlled subsidiaries. The operating partnership owns economic interests in two taxable corporations, Rockledge Hotel Properties and Fernwood Hotel Assets, Inc., which we refer to as "non-controlled subsidiaries". These non-controlled subsidiaries hold various assets which, under our credit facility, may not exceed, in the aggregate, 15% of the value of our assets. The assets held by the non- controlled subsidiaries consist primarily of interests in partnerships which own hotels that are not leased to third parties, hotels that are not leased to third parties, some furniture, fixtures, and equipment (FF&E) used in our hotels and some international hotels. For example, Rockledge Hotel Properties owns approximately a 50% non-controlling interest in the CBM Joint Venture which owns 120 Courtyard by Marriott properties. If the operating partnership owned more than a de minimis amount of any of these assets, it could jeopardize our REIT status and/or the status of the operating partnership as a partnership for federal income tax purposes. Although the operating partnership owns approximately 95% of the total economic interests of the non-controlled subsidiaries, it owns none of the voting stock of the non-controlled subsidiaries. The Host Marriott Statutory Employee/Charitable Trust, the beneficiaries of which are (1) a trust formed for the benefit of a number of our employees and (2) the J. Willard and Alice S. Marriott Foundation, owns all of the voting common stock, representing approximately 5% of the total economic interests in the non-controlled subsidiaries. The Host Marriott Statutory Employee/Charitable Trust elects the directors who are responsible for overseeing the operations of the non-controlled subsidiaries. The directors are currently our employees, although this is not required. As a result, we have no control over the operation or management of the hotels or other assets owned by the non-controlled subsidiaries, even though we depend upon the non-controlled subsidiaries for a portion of our revenues. Also, the activities of the non- controlled subsidiaries could cause us to be in default under our principal credit facilities. Effective January 1, 2001, we are able to own all of the voting stock of the non-controlled subsidiaries without adversely affecting our REIT status so long as they elect to be "taxable REIT subsidiaries" as defined under the REIT Modernization Act. We are considering pursuing a transaction with the Host Marriott Statutory Employee/Charitable Trust that would allow us to acquire control of the non-controlled subsidiaries, although we have not reached any such agreement and cannot assure you that any such agreement will be reached or that a transaction will be consummated. Whether or not such an agreement is reached, effective January 1, 2001, each of the non-controlled subsidiaries will elect to be treated as a taxable REIT subsidiary. See "--REIT Modernization Act changes to the REIT asset tests". Our relationship with Marriott International may result in conflicts of interest. Marriott International, a public hotel management company, manages a significant number of our hotels. In addition, Marriott International manages hotels that compete with our hotels. As a result, Marriott International may make decisions regarding competing lodging facilities which it manages that would not necessarily be in our best interests. J.W. Marriott, Jr. is a member of our Board of Directors and his brother, Richard E. Marriott, is our Chairman of the Board. Both J.W. Marriott, Jr. and Richard E. Marriott serve as S-13

directors, and J.W. Marriott, Jr. also serves as an officer, of Marriott International. J.W. Marriott, Jr. and Richard E. Marriott beneficially own, as determined for securities law purposes, as of January 31, 2001, approximately 10.8% and 10.6%, respectively, of the outstanding shares of common stock of Marriott International. As a result, J.W. Marriott, Jr. and Richard E. Marriott have potential conflicts of interest as our directors when making decisions regarding Marriott International, including decisions relating to the management agreements involving the hotels and Marriott International's management of competing lodging properties. Both our Board of Directors and the Board of Directors of Marriott International follow appropriate policies and procedures to limit the involvement of Messrs. J.W. Marriott, Jr. and Richard E. Marriott in conflict situations, including requiring them to abstain from voting as directors of either us or Marriott International or our or their subsidiaries on matters which present a conflict between the companies. If appropriate, these policies and procedures will apply to other directors and officers. See "--We may acquire hotel properties through joint ventures with third parties that could result in conflicts". Some of our hotel revenues are subject to the prior rights of lenders. The mortgages on 28 of our hotels require that revenues from these hotels be used first to pay the debt service on the mortgage loans. Consequently, only the cash flow remaining after debt service on those mortgage loans will be available to satisfy other obligations, including property taxes and insurance, FF&E reserves for the hotels and capital improvements, and to make distributions to our shareholders (including the payment of dividends to holders of the Class C preferred stock). We have substantial indebtedness. Our degree of leverage could affect our ability to: . obtain financing in the future for working capital, capital expenditures, acquisitions, development or other general business purposes; . undertake financings on terms and conditions acceptable to us; . pursue our acquisition strategy; or . compete effectively or operate successfully under adverse economic conditions. If our cash flow and working capital are not sufficient to fund our expenditures or service our indebtedness, we would have to raise additional funds through: . the sale of equity; . the refinancing of all or part of our indebtedness; . the incurrence of additional permitted indebtedness; or . the sale of assets. We cannot assure you that any of these sources of funds would be available in amounts sufficient for us to meet our obligations or fulfill our business plans. Additionally, our debt contains performance related covenants that, if not achieved, could require immediate repayment of our debt or significantly increase the rate of interest on our debt. A reduction in hotel revenues would directly affect our earnings and cash flows. Prior to January 1, 2001, we received rental income from our hotels leased to Crestline subsidiaries which was based on hotel-level sales of rooms, food and beverage and other items. A portion of this rental income was guaranteed by Crestline. Beginning January 1, 2001, as a result of HMT Lessee's acquisition of the S-14

Crestline leasehold interests, HMT Lessee, through its subsidiaries, will receive the earnings and cash flows from hotel-level sales directly and we will no longer have the protection of the Crestline guarantee. Accordingly, a reduction in hotel revenues or an increase in hotel expenses would have a direct effect on our earnings and cash flows and could have an adverse impact on our ability to make payments on our obligations including debt service, operating expenses, capital improvements and dividends to our shareholders (including the payment of dividends to holders of the Class C preferred stock). There is no limitation on the amount of debt we may incur. There are no limitations in our organizational documents or those of the operating partnership that limit the amount of indebtedness that we may incur. However, our existing debt instruments contain restrictions on the amount of indebtedness that we may incur. Accordingly, we could incur indebtedness to the extent permitted by our debt agreements. If we became more highly leveraged, our debt service payments would increase and our cash flow and our ability to service our debt and make distributions to our shareholders (including the payment of dividends to holders of the Class C preferred stock) would be adversely affected. Our management agreements could impair the sale or other disposition of our hotels. Under the terms of the management agreements, we generally may not sell, lease or otherwise transfer the hotels unless the transferee assumes the related management agreements and meets other specified conditions. Our ability to finance, refinance or sell any of our hotel properties subject to a management agreement may, depending upon the structure of such transactions, require the manager's consent. If the manager did not consent, we would be prohibited from financing, refinancing or selling the property without breaching the management agreement. The acquisition contracts relating to some hotels limit our ability to sell or refinance those hotels. For reasons relating to federal income tax considerations of the former owners of some of our hotels, we have agreed to restrictions on selling some hotels or repaying or refinancing the mortgage debt on those hotels for varying periods depending on the hotel. We anticipate that, in specified circumstances, we may agree to similar restrictions in connection with future hotel acquisitions. As a result, even if it were in our best interests to sell or refinance the mortgage debt on hotels for which we have agreed to such restrictions, it may be difficult or impossible to do so during their respective lock-out periods. Our ground lease payments may increase faster than the revenues we receive on the hotels. As of February 1, 2001, we lease 46 of our hotels pursuant to ground leases with third parties. These ground leases generally require increases in ground rent payments every five years. Our ability to make distributions to shareholders (including the payment of dividends to holders of the Class C preferred stock) could be adversely affected to the extent that our revenues do not increase at the same or a greater rate as the increases under the ground leases. In addition, if we were to sell a hotel encumbered by a ground lease, the buyer would have to assume the ground lease, which could result in a lower sales price. Moreover, to the extent that such ground leases are not renewed at their expiration, there could be a material adverse effect on our business. New acquisitions may fail to perform as expected or we may be unable to make acquisitions on favorable terms. We intend to acquire additional full-service hotels. Newly acquired properties may fail to perform as expected, which could adversely affect our financial condition. We may underestimate the costs necessary to bring an acquired property up to standards established for its intended market position. We expect to acquire hotels with cash from secured or unsecured financings and proceeds from offerings of equity or debt, to the extent available. We may not be in a position or have the opportunity in the future to make suitable property acquisitions on favorable terms. S-15

We may be unable to sell properties when appropriate because real estate investments are illiquid. Real estate investments generally cannot be sold quickly. We may not be able to vary our portfolio promptly in response to economic or other conditions. The inability to respond promptly to changes in the performance of our investments could adversely affect our financial condition and ability to service debt and make distributions to shareholders (including the payment of dividends to holders of the Class C preferred stock). In addition, there are limitations under the federal tax laws applicable to REITs and, as discussed above, there are acquisition contracts that we entered into when we acquired some of our properties that may limit our ability to recognize the full economic benefit from a sale of our assets. The reliability of market data included in this prospectus supplement is uncertain. The market data included in this prospectus supplement, including information relating to our relative position in the industry, is based on independent industry publications, other publicly available information, studies performed for us by independent consultants or our management's good faith beliefs. Although we believe that such independent sources are reliable, the accuracy and completeness of such information is not guaranteed and has not been independently verified. Competition for acquisitions may result in increased prices for hotels. Other major investors with significant capital compete with us for attractive investment opportunities. These competitors include other REITs and hotel companies, investment banking firms and private institutional investment funds. This competition may increase prices for hotel properties, thereby decreasing the potential return on our investments. Our revenues and the value of our properties are subject to conditions affecting the lodging industry. If our assets do not generate income sufficient to pay our expenses, service our debt and maintain our properties, we will be unable to make distributions to our shareholders (including the payment of dividends to holders of the Class C preferred stock). Our revenues and the value of our properties are subject to conditions affecting the lodging industry. These include: . changes in the national, regional and local economic climate; . local conditions such as an oversupply of hotel properties or a reduction in demand for hotel rooms; . the attractiveness of our hotels to consumers and competition from comparable hotels; . the quality, philosophy and performance of the managers of our hotels; . changes in room rates and increases in operating costs due to inflation and other factors; and . the need to periodically repair and renovate our hotels. If there is an adverse changes in any of these conditions, it could adversely affect our financial performance and the value of our properties. Our expenses may remain constant even if our revenue drops. The expenses of owning real estate property are not necessarily reduced when circumstances like market factors and competition cause a reduction in income from the property. If a property is mortgaged and we are unable to meet the mortgage payments, the lender could foreclose and take the property. Our financial condition could be adversely affected by: . interest rate levels; . the availability of financing; S-16

. the cost of compliance with government regulation, including zoning and tax laws; and . changes in governmental regulations, including those governing usage, zoning and taxes. We depend on key personnel. We depend on the efforts of our executive officers and other key personnel. While we believe that we could find replacements for these key personnel, the loss of their services could have a significant adverse effect on our operations. The operating partnership does not intend to obtain key-man life insurance with respect to any of our personnel. Partnership and other litigation judgments or settlements could have a material adverse effect on our financial condition. We could be subject to judgments or enter into settlements with respect to litigation resulting from our investments in partnerships that could have a material adverse effect on our financial condition. We have made several investments in partnerships that own hotel properties. Prior to the REIT conversion, we and several of our subsidiaries maintained these investments and conducted the partnerships' businesses through general and limited partnership interests in the partnerships. In connection with the REIT conversion, most of these interests were either contributed to our non- controlled subsidiaries or were acquired by the operating partnership. We and our subsidiaries have been parties to various lawsuits brought by limited partners in these partnerships relating to our management of the partnerships' businesses and certain previous transactions entered into with or on behalf of the partnerships, including the REIT conversion. We have settled many of these lawsuits. However, we continue to be subject to several such lawsuits. While we believe all of the lawsuits in which we are a defendant are without merit and we are vigorously defending against such claims, we can give no assurance as to the outcome of any of the lawsuits. Additionally, there can be no assurance that we or our subsidiaries have not taken or will not, from time to time, take an action, or have not caused or will not cause a partnership in which we are the general partner to take an action, that will result in a lawsuit being brought against us or our subsidiaries by limited partners in such partnership. For a discussion of the settlements, see "Recent Developments" and for a discussion of our ongoing lawsuits, see "Business--Legal Proceedings" and the documents which are incorporated by reference in the accompanying prospectus. In connection with the REIT conversion, the operating partnership has assumed all liability arising under legal proceedings filed against us and will indemnify us as to all such matters. If any current or future lawsuit were to be determined adversely to us or a settlement involving a payment of a material sum of money were to occur, there could be a material adverse effect on our financial condition. We may acquire hotel properties through joint ventures with third parties that could result in conflicts. Instead of purchasing hotel properties directly, we may invest as a co- venturer. Joint venturers often share control over the operation of the joint venture assets. For example, in December 2000 our non-controlled subsidiary, Rockledge Hotel Properties, entered into the CBM Joint Venture with Marriott International and their affiliates. Rockledge Hotel Properties has approximately a 50% non-controlling interest in this entity, which owns 120 Courtyard by Marriott properties. Actions by a co-venturer could subject the assets to additional risk, including: . our co-venturers might have economic or business interests or goals that are inconsistent with our interests or goals; . our co-venturers may be in a position to take actions contrary to our instructions or requests or contrary to our policies or objectives; or . our co-venturers could go bankrupt, leaving us liable for its share of joint venture liabilities. S-17

Although we generally will seek to maintain sufficient control of any joint venture to permit our objectives to be achieved, we might not be able to take action without the approval of our joint venture partners. Also, our joint venture partners could take actions binding on the joint venture without our consent. Environmental problems are possible and can be costly. We believe that the properties that we own are in compliance in all material respects with applicable environmental laws. Unidentified environmental liabilities could arise, however, and could have a material adverse effect on our financial condition and performance. Federal, state and local laws and regulations relating to the protection of the environment may require a current or previous owner or operator of real estate to investigate and clean up hazardous or toxic substances or petroleum product releases at the property. The owner or operator may have to pay a governmental entity or third parties for property damage and for investigation and clean-up costs incurred by the parties in connection with the contamination. These laws typically impose clean-up responsibility and liability without regard to whether the owner or operator knew of or caused the presence of the contaminants. Even if more than one person may have been responsible for the contamination, each person covered by the environmental laws may be held responsible for all of the clean-up costs incurred. In addition, third parties may sue the owner or operator of a site for damages and costs resulting from environmental contamination emanating from that site. Environmental laws also govern the presence, maintenance and removal of asbestos. These laws require that owners or operators of buildings containing asbestos properly manage and maintain the asbestos, they notify and train those who may come into contact with asbestos and they undertake special precautions, including removal or other abatement, if asbestos would be disturbed during renovation or demolition of a building. These laws may impose fines and penalties on building owners or operators who fail to comply with these requirements and may allow third parties to seek recovery from owners or operators for personal injury associated with exposure to asbestos fibers. Compliance with government regulations can be costly. Our hotels are subject to various forms of regulation, including Title III of the Americans with Disabilities Act (ADA), building codes and regulations pertaining to fire safety. Compliance with those laws and regulations could require substantial capital expenditures. These regulations may be changed from time to time, or new regulations adopted, resulting in additional or unexpected costs of compliance. In addition, noncompliance with the ADA could result in the imposition of fines or an award of damages to private litigants. Any increased costs to comply with applicable regulations or to pay fines or damages could reduce the cash available for servicing debt and making distributions to our shareholders (including the payment of dividends to holders of the Class C preferred stock). Some potential losses are not covered by insurance. We carry comprehensive liability, fire, flood, extended coverage and rental loss, for rental losses extending up to 12 months, insurance with respect to all of our hotels. We believe the policy specifications and insured limits of these policies are of the type customarily carried for similar hotels. Some types of losses, such as from earthquakes and environmental hazards, however, may be either uninsurable or too expensive to justify insuring against. Should an uninsured loss or a loss in excess of insured limits occur, we could lose all or a portion of the capital we have invested in a hotel, as well as the anticipated future revenue from the hotel. In that event, we might nevertheless remain obligated for any mortgage debt or other financial obligations related to the property. We depend on external sources of capital for future growth. As with other REITs, but unlike corporations generally, our ability to reduce our debt and finance our growth largely must be funded by external sources of capital because we generally will have to distribute to our shareholders 90% of our taxable income in order to qualify as a REIT, including taxable income where we do not receive corresponding cash. For taxable years prior to January 1, 2001, we were required to distribute 95% S-18

of our taxable income to qualify as a REIT. Our access to external capital will depend upon a number of factors, including general market conditions, the market's perception of our growth potential, our current and potential future earnings, cash distributions and the market price of our common stock. Currently, our access to external capital has been limited to the extent that our common stock is trading at what we believe is a discount to our estimated net asset value. Federal income tax risks General. We believe that we have been organized and have operated in such a manner so as to qualify as a REIT under the Internal Revenue Code, commencing with our taxable year beginning January 1, 1999. A REIT generally is not taxed at the corporate level on income it currently distributes to its shareholders as long as it distributes at least 90% of its taxable income, excluding net capital gain. No assurance can be provided, however, that we qualify as a REIT or that new legislation, Treasury Regulations, administrative interpretations or court decisions will not significantly change the tax laws with respect to our qualification as a REIT or the federal income tax consequences of such qualification. Required distributions and payments. To continue to qualify as a REIT, we currently are required each year to distribute to our shareholders at least 90% of our taxable income, excluding net capital gain (for our taxable years that ended prior to January 1, 2001, we were required to distribute 95% of this amount to so qualify). Due to some transactions entered into in years prior to the REIT conversion, we expect to recognize substantial amounts of "phantom" income, which is taxable income that is not matched by cash flow. In addition, we will be subject to a 4% nondeductible excise tax on the amount, if any, by which our distributions in any calendar year are less than the sum of 85% of our ordinary income and 95% of our capital gain net income for that year and any undistributed taxable income from prior periods. We intend to make distributions to our shareholders to comply with the distribution requirement and to avoid the nondeductible excise tax and will rely for this purpose on distributions from the operating partnership. However, differences in timing between taxable income and cash available for distribution due to, among other things, the cyclical nature of the lodging industry and the fact that some taxable income will be "phantom" income could require us to borrow funds or to issue additional equity to enable us to meet the distribution requirement and, therefore, to maintain our REIT status, and to avoid the nondeductible excise tax. The operating partnership is required to pay, or reimburse us, as its general partner, for some taxes and other liabilities and expenses that we incur, including all taxes and liabilities attributable to periods and events prior to the REIT conversion. In addition, because the REIT distribution requirements prevent us from retaining earnings, we will generally be required to refinance debt that matures with additional debt or equity. We cannot assure you that any of these sources of funds, if available at all, would be sufficient to meet our distribution and tax obligations. Adverse consequences of our failure to qualify as a REIT. If we fail to qualify as a REIT, we will be subject to federal income tax, including any applicable alternative minimum tax, on our taxable income at regular corporate rates. In addition, unless entitled to statutory relief, we will not qualify as a REIT for the four taxable years following the year during which REIT qualification is lost. The additional tax burden on us would significantly reduce the cash available for distributions to our shareholders (including the payment of dividends to holders of the Class C preferred stock) and we would no longer be required by the rules applicable to REITs to make any distributions to holders of our stock. Our failure to qualify as a REIT could reduce materially the value of our stock and would cause any distributions to shareholders that otherwise would have been subject to tax as capital gain dividends to be taxable as ordinary income to the extent of our current and accumulated earnings and profits, or E&P. However, in this case, subject to limitations under the Internal Revenue Code, corporate distributees may be eligible for the dividends received deduction with respect to our distributions. Our failure to qualify as a REIT also would result in a default under our senior notes and our credit facility. S-19

Our earnings and profits attributable to our non-REIT taxable years. In order to qualify as a REIT, we cannot have at the end of any taxable year any undistributed E&P that is attributable to one of our non-REIT taxable years. A REIT has until the close of its first taxable year as a REIT in which it has non-REIT E&P to distribute such accumulated E&P. We were required to have distributed this E&P prior to the end of 1999, the first taxable year for which our REIT election was effective. If we failed to do this, we will be disqualified as a REIT at least for taxable year 1999. We believe that distributions of non-REIT E&P that we made were sufficient to distribute all of the non-REIT E&P as of December 31, 1999, but there could be uncertainties relating to the estimate of our non-REIT E&P and the value of the Crestline stock that we distributed to our shareholders. Therefore, we cannot guarantee that we met this requirement. Treatment of leases. To qualify as a REIT, we must satisfy two gross income tests, under which specified percentages of our gross income must be passive income, like rent. For the rent paid pursuant to the leases, which constitutes substantially all of our gross income, to qualify for purposes of the gross income tests, the leases must be respected as true leases for federal income tax purposes and not be treated as service contracts, joint ventures or some other type of arrangement. In addition, the lessees must not be regarded as "related party tenants," as defined in the Internal Revenue Code. We believe, taking into account both the terms of the leases and the expectations that we and the lessees have with respect to the leases, that the leases will be respected as true leases for federal income tax purposes. There can be no assurance, however, that the IRS will agree with this view. If the leases were not respected as true leases for federal income tax purposes or if the lessees were regarded as "related party tenants," we would not be able to satisfy either of the two gross income tests applicable to REITs and we would lose our REIT status. See "--Adverse consequences of our failure to qualify as a REIT" above. For our taxable years beginning on and after January 1, 2001, as a result of the REIT Modernization Act, we are permitted to lease our hotels to a subsidiary of the operating partnership that is taxable as a corporation and that elects to be treated as a "taxable REIT subsidiary." Accordingly, effective January 1, 2001, HMT Lessee, a newly created, wholly owned subsidiary of the operating partnership, directly or indirectly acquired all but one of the full-service hotel leasehold interests formerly held by Crestline. So long as HMT Lessee qualifies as a taxable REIT subsidiary of ours, it will not be treated as a "related party tenant." We believe that, effective January 1, 2001, HMT Lessee will qualify to be treated as a taxable REIT subsidiary for federal income tax purposes. We cannot assure you, however, that the IRS will not challenge its status as a taxable REIT subsidiary for federal income tax purposes, or that a court would not sustain such a challenge. If the IRS were successful in disqualifying HMT Lessee from treatment as a taxable REIT subsidiary, we would fail to meet the asset tests applicable to REITs and, accordingly, cease to qualify as a REIT. See "--Adverse consequences of our failure to qualify as a REIT" above. Other tax liabilities; our substantial deferred and contingent tax liabilities. Notwithstanding our status as a REIT, we are subject, through our ownership interest in the operating partnership, to certain federal, state and local taxes on our income and property. In addition, we will be required to pay federal tax at the regular maximum corporate rate, currently 35%, upon our share of any "built-in gain" recognized as a result of any sale before January 1, 2009, by the operating partnership of assets, including the hotels, in which interests were acquired by the operating partnership from our predecessor and its subsidiaries as part of the REIT conversion. Built-in gain is the amount by which an asset's fair market value exceeded our adjusted basis in the asset on January 1, 1999, the first day of our first taxable year as a REIT. At the time of the REIT conversion, we expected that we or a non-controlled subsidiary likely would recognize substantial built-in gain and deferred tax liabilities in the next ten years without any corresponding receipt of cash by us or the operating partnership. We recognized a substantial amount of these built-in gains and deferred tax liabilities in 1999. Accordingly, our potential tax exposure on these gains and deferred liabilities for the future is significantly less than it was at the time of our REIT conversion. The operating partnership is S-20

obligated under its partnership agreement to pay all such taxes incurred by us, as well as any liabilities that the IRS may assert against us for corporate income taxes for taxable years prior to the time we qualified as a REIT. The non-controlled subsidiaries and any of our taxable REIT subsidiaries, including HMT Lessee, are fully taxable as corporations and will pay federal and state income tax on their net income at the applicable corporate rates. The operating partnership's failure to qualify as a partnership. We believe that the operating partnership qualifies as a partnership for federal income tax purposes. No assurance can be provided, however, that the IRS will not challenge its status as a partnership for federal income tax purposes, or that a court would not sustain such a challenge. If the IRS were successful in treating the operating partnership as a corporation for tax purposes, we would fail the asset tests applicable to REITs and, accordingly, cease to qualify as a REIT. See "--Adverse consequences of our failure to qualify as a REIT" above. Also, the imposition of a corporate tax on the operating partnership would reduce significantly the amount of cash available for distribution to its limited partners, including us. Finally, the classification of the operating partnership as a corporation would cause us to recognize gain at least equal to our "negative capital accounts," and possibly more, depending upon the circumstances. REIT Modernization Act changes to the REIT asset tests. Subject to the exceptions discussed in this paragraph, a REIT is prohibited from owning securities in any one issuer if the value of those securities exceeds 5% of the value of the REIT's total assets or the securities owned by the REIT represent more than 10% of the issuer's outstanding voting securities or, for taxable years beginning on or after January 1, 2001, more than 10% of the value of the issuer's outstanding securities. For taxable years beginning on or after January 1, 2001, as a result of the REIT Modernization Act, a REIT is permitted to own securities of a subsidiary that exceed the 5% value test and the 10% vote or value test if the subsidiary elects to be a "taxable REIT subsidiary," which is fully taxable as a corporation. However, a REIT may not own securities of taxable REIT subsidiaries that represent in the aggregate more than 20% of the value of the REIT's total assets. Effective January 1, 2001, each of the non-controlled subsidiaries and HMT Lessee will elect to be treated as a taxable REIT subsidiary. Several provisions of the REIT Modernization Act ensure that a taxable REIT subsidiary is subject to an appropriate level of federal income taxation. For example, a taxable REIT subsidiary is limited in its ability to deduct interest payments made to an affiliated REIT. In addition, the REIT has to pay a 100% penalty tax on some payments that it receives if the economic arrangements between the REIT and the taxable REIT subsidiary are not comparable to similar arrangements between unrelated parties. We may be required to pay a penalty tax upon the sale of a hotel. The federal income tax provisions applicable to REITs provide that any gain realized by a REIT on the sale of property held as inventory or other property held primarily for sale to customers in the ordinary course of business is treated as income from a "prohibited transaction" that is subject to a 100% penalty tax. Under existing law, whether property, including hotels, is held as inventory or primarily for sale to customers in the ordinary course of business is a question of fact that depends upon all of the facts and circumstances with respect to the particular transaction. The operating partnership intends that it and its subsidiaries will hold the hotels for investment with a view to long-term appreciation, to engage in the business of acquiring and owning hotels and to make occasional sales of hotels as are consistent with the operating partnership's investment objectives. We cannot assure you, however, that the IRS might not contend that one or more of these sales is subject to the 100% penalty tax, particularly if the hotels that are sold have been held for a relatively short period of time. S-21

USE OF PROCEEDS We expect our net proceeds from the offering, after deducting the underwriting discounts and commissions and estimated expenses payable by us, will be approximately $125 million, or approximately $144 million if the over- allotment option granted to the underwriters is exercised in full. We will contribute the net proceeds from the offering to the operating partnership in exchange for preferred units of the operating partnership which will have economic terms substantially similar to those of the Class C preferred stock. The operating partnership will use these net proceeds for general business purposes, which may include: . the repayment of indebtedness (including amounts outstanding under our bank credit facility); and . the acquisition or development of hotel properties. Pending application of the net proceeds by the operating partnership for the foregoing purposes, the operating partnership may invest the net proceeds in short-term interest bearing investment grade securities.

(5) Represents (a) minority interest related to the operating partnership of approximately 63.8 million and 51.3 million common and preferred operating partnership units on a historical and pro forma basis, respectively, held by unaffiliated parties which represents approximately 22% and 18% of the operating partnership units outstanding on a historical and pro forma basis, respectively, and (b) minority interests in consolidated investments of the operating partnership of $133 million on both a historical and pro forma basis. The result of the decrease in minority interest related to the operating partnership is a corresponding increase in additional paid-in capital. S-23

The pro forma financial statements reflect the following transactions: 2001 Transactions: . Offering of Class C preferred stock made hereby; . The February 2001 exchange of 12.5 million units of the operating partnership for Host Marriott common stock by The Blackstone Entities, which increases our ownership of the operating partnership from 78% to 82%, thereby affecting the calculation of minority interest; and . Acquisition by HMT Lessee, effective January 1, 2000, of the equity interests in the lessees of 112 of our full-service hotels and the leasehold interests in four of our full-service hotels from Crestline for approximately $207 million, of which $40 million was funded through additional borrowings under the bank credit facility. See "Recent Developments" for a description of this transaction, including the changes in our income statement presentation. 2000 Transactions: . November cash payments of $81 million by the operating partnership in settlement of certain litigation described under "Recent Developments". The settlement of the litigation includes an investment in Rockledge Hotel Properties of $26 million by the operating partnership, a loan to Rockledge Hotel Properties of $39 million by the operating partnership and the payment of $14 million owed to Rockledge Hotel Properties by the operating partnership.

BUSINESS The disclosure set forth below amends and supplements the discussion of our business contained in the documents which are incorporated by reference into the accompanying prospectus. We are a self-managed and self-administered real estate investment trust, or "REIT," owning full service hotel properties. We were formed as a Maryland corporation in 1998, under the name HMC Merger Corporation, as a wholly owned subsidiary of Host Marriott Corporation, a Delaware corporation, in connection with its efforts to reorganize its business operations to qualify as a REIT for federal income tax purposes. As part of this reorganization, which we refer to as the REIT conversion, and which is described below in more detail, on December 29, 1998, we merged with Host Marriott and changed our name to Host Marriott Corporation. As a result, we have succeeded to the hotel ownership business formerly conducted by Host Marriott. We conduct our business as an umbrella partnership REIT, or UPREIT, through Host Marriott, L.P., or the "operating partnership", a Delaware limited partnership, of which we are the sole general partner and in which we held approximately 78% of the outstanding partnership interests at September 8, 2000. On February 7, 2001, affiliates of The Blackstone Group converted 12.5 million units of the operating partnership to common stock and immediately sold the 12.5 million shares of common stock in an underwritten public offering. As a result, we now own approximately 82% of the operating partnership and we have an additional 12.5 million shares of common stock outstanding. See the section entitled "Recent Developments" for a more detailed discussion of this transaction. Together with the operating partnership, we were formed primarily to continue, in an UPREIT structure, the full service hotel ownership business formerly conducted by Host Marriott and its subsidiaries. Our primary business objective is to provide superior total returns to our shareholders through a combination of dividends, appreciation in net asset value per share, and growth in funds from operations per share, or FFO, as defined by the National Association of Real Estate Investment Trusts (i.e., net income computed in accordance with generally accepted accounting principles, excluding gains or losses from debt restructuring and sales of properties, plus real estate- related depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures), by focusing on aggressive asset management and disciplined capital allocation. In addition, we endeavor to: . maximize the value of our existing portfolio through an aggressive asset management program which focuses on selectively improving and expanding our hotels; . acquire additional existing and newly developed upscale and luxury full service hotels in targeted markets primarily focusing on downtown hotels in core business districts in major metropolitan markets and select airport and resort/convention locations; . complete our current development and expansion program, and selectively develop and construct new upscale and luxury full service hotels; . regenerate capital through opportunistic asset sales and selectively dispose of noncore assets; . repurchase our stock under our buyback program as market conditions permit; and . opportunistically pursue other real estate investments. Our operations are conducted solely through the operating partnership and its subsidiaries. As of February 1, 2001, we own 122 full-service hotels, containing approximately 58,000 rooms, located throughout the United States and Canada. The hotels are generally operated under the Marriott, Ritz-Carlton, Four Seasons, Hilton, Hyatt and Swissotel brand names. These brand names are among the most respected and widely recognized brand names in the lodging industry. We are the sole general partner of the operating partnership and manage all aspects of the business of the operating partnership. This includes decisions with respect to: . sales and purchases of hotels; . the financing of the hotels; S-32

. the leasing of the hotels; and . capital expenditures for the hotels subject to the terms of the leases and the management agreements. We are managed by our Board of Directors and have no employees who are not also employees of the operating partnership. Due to certain tax laws restricting REITs from deriving revenues directly from the operations of hotels, our hotels were leased by the operating partnership and its subsidiaries to third party lessees, including primarily Crestline and its subsidiaries, and managed on behalf of the lessees by nationally recognized hotel operators such as Marriott International, Four Seasons, Hyatt, Interstate and other companies. The REIT Modernization Act, which was enacted in December 1999 and is discussed in more detail below, amended the tax laws to permit REITs, effective January 1, 2001, (1) to lease hotels to a subsidiary that qualifies as a taxable REIT subsidiary, which is a subsidiary of the REIT that is subject to regular corporate tax, and (2) to own all of the voting stock of such taxable REIT subsidiary, although the hotels must be operated on behalf of the taxable REIT subsidiary by managers that are unrelated third parties. Accordingly, effective January 1, 2001, a newly created wholly owned subsidiary of the operating partnership, HMT Lessee, that will elect to be treated as a taxable REIT subsidiary effective January 1, 2001, purchased the equity interests in the lessees of 112 of our full-service hotels and the leasehold interests in four of our full-service hotels from Crestline. See "Recent Developments" for a description of the acquisition of the leasehold interests from Crestline. The economic trends affecting the hotel industry and the overall economy will be a major factor in generating growth in revenues, and the abilities of the managers will also have a material impact on future hotel level sales and operating profit growth. Our hotel properties may be impacted by inflation through its effect on increasing costs, as well as recent increases in energy costs. Unlike other real estate, hotels have the ability to change room rates on a daily basis, so the impact of higher inflation often can be passed on to customers, particularly in the transient segment. However, an economic downturn may affect the managers' ability to increase room rates. Through our strategic restructuring of our balance sheet, nearly 95% of our debt bears interest at fixed rates, which mitigates the impact of rising interest rates. We endeavor to selectively acquire upscale and luxury full-service hotel lodging properties that complement our existing portfolio of high-end hotels. Based upon data provided by Smith Travel Research, we believe that our full- service hotels outperform the industry's average occupancy rate by a significant margin, averaging 79.5% and 79.3% occupancy for our comparable properties for the First Three Quarters 2000 and 1999, respectively, compared to a 72.1% and 70.3% average occupancy for our competitive set for the same periods in 2000 and 1999, respectively. Our "comparable properties" consist of 114 hotels, owned directly or indirectly by us for the First Three Quarters 2000 and 1999, respectively, net of one property that sustained substantial fire damage during 2000, two properties where significant expansion at the hotels affected operations, five properties where reported results were affected by a change in reporting period, and the Tampa Waterside Marriott, which opened in February 2000. Our "competitive set" refers to hotels in the upscale and luxury full-service segment of the lodging industry, the segment which is most representative of our full service hotels, and consists of Crowne Plaza; Doubletree; Hyatt; Hilton; Radisson; Renaissance; Sheraton; Westin; and Wyndham. In addition to external growth generated by new acquisitions, we intend to aggressively manage our existing assets by carefully and periodically reviewing our portfolio to identify opportunities to selectively enhance operating performance through major capital improvements. In 2000, the relatively high occupancy rates of our hotels, along with increased demand for full-service hotel rooms, allowed the managers of our hotels to increase average daily room rates by selectively raising room rates for certain types of bookings and by minimizing, in specified cases, discounted group business, replacing it with higher-rate group and transient business. As a result, on a comparable basis, room revenue per available room ("REVPAR") for our full-service properties increased approximately 6.6% in the First Three S-33

Quarters 2000 over the comparable period in 1999. There can be no assurance that our managers will be able to continue using this mix of business to increase average daily room rates. Business Strategy Our primary business objective is to provide superior total returns to our shareholders through a combination of dividends, appreciation in net asset value per share, and growth in FFO per share. In order to achieve this objective we employ the following strategies: . acquire existing upscale and luxury full-service hotels as market conditions permit, including Marriott and Ritz-Carlton hotels and other hotels operated by leading management companies such as Four Seasons, Hyatt, and Hilton which satisfy our investment criteria--these acquisitions may be completed through various means including acquisitions in which we are already a partner, public and private portfolio transactions, and entering into joint ventures when we believe our return on investment will be maximized by doing so; . complete the development of our existing pipeline, including the 295-room Ritz-Carlton, Naples, Golf Resort, the 50,000 square-foot spa also at the Ritz-Carlton, Naples, and the 200-room expansion of the Memphis Marriott, as well as selectively expand existing properties and develop new upscale and luxury full-service hotels, operated by leading management companies, which satisfy our investment criteria and employ transaction structures which mitigate our risk; . maximize the value of our existing portfolio through aggressive asset management, including completing selective capital improvements and expansions that are designed to increase gross hotel sales or improve operations; and . regenerate capital through opportunistic asset sales and selectively dispose of noncore assets, including older assets with significant capital needs, assets that are at risk given potential new supply, or assets in slower-growth markets. HMT Lessee's acquisition of the leasehold interests from Crestline simplifies our corporate structure, enables us to better control our portfolio of hotels, and is expected to be accretive to future earnings and cash flows, as the lessees have recorded substantial earnings and cash flow in the First Three Quarters 2000 and Full Year 1999, although there can be no guarantee that such trends will continue. For a discussion of the risks related to HMT Lessee's acquisition of the leasehold interests, see "Risk Factors--A reduction in hotel revenues would directly affect our earnings and cash flows". Competition for acquisitions has increased and the availability of suitable acquisition candidates that complement our portfolio of high-end hotels has been limited recently due to market conditions. Most products in the market consist of smaller, suburban hotels, and, as many luxury hotel owners are choosing to hold on to their assets at this time, competition for the limited number of available properties in the top markets has caused them to be generally not competitively priced. However, we believe that acquisitions that meet our stringent criteria will provide the highest and best use of our capital as they become available. Our acquisition strategy focuses on the upscale and luxury full-service segments of the market, which we believe will continue to offer opportunities over time to acquire assets at attractive multiples of cash flow and at discounts to replacement value. Our acquisition criteria continues to focus on: . properties in difficult to duplicate locations with high costs to prospective competitors, such as hotels located in urban, airport and resort/convention locations; . premium brand names, such as Marriott, Ritz-Carlton, Four Seasons, Hilton, and Hyatts; . underperforming hotels which can be improved by conversion to high quality brands; and . properties which are operated by leading management companies such as Marriott, Ritz-Carlton, Four Seasons, Hilton, and Hyatt. S-34

In recent years, we have increased our pool of potential acquisition candidates to include select non-Marriott and non-Ritz-Carlton branded hotels which offer long-term growth potential, have high quality managers and are consistent with the overall quality of our portfolio. For example, in December 1998 we acquired a portfolio of hotels consisting of two Ritz-Carlton properties, two Four Seasons properties, one Grand Hyatt property, three Hyatt Regency properties and four Swissotel properties. Our current portfolio of hotels are operated under the Marriott, Ritz- Carlton, Four Seasons, Hilton, Hyatt and Swissotel brand names. In general, based upon data provided by Smith Travel Research, we believe that these premium brands have consistently outperformed the industry. Demonstrating the strength of our portfolio, our comparable properties, as previously defined on page S-33, generated a 30% and 32% REVPAR premium over our competitive set for the First Three Quarters 2000 and 1999, respectively. Based on the strength of our portfolio of premium hotels, management anticipates that any additional full- service properties acquired in the future and converted from other brands to one of our premium brands should achieve increases in occupancy rates and average room rates as the properties begin to benefit from brand name recognition, national reservation systems and group sales organizations. Since the beginning of fiscal year 1994, we have acquired 15 hotels that we have converted to premium brands. We believe we are well qualified to pursue our acquisition and development strategy. Management has extensive experience in acquiring and financing lodging properties and believes its industry knowledge, relationships and access to market information provide a competitive advantage with respect to identifying, evaluating and acquiring hotel assets. Our asset management team, which is comprised of individuals with exceptional industry knowledge and relationships, focuses on maximizing the value of our existing portfolio through: . monitoring property and brand performance; . pursuing expansion and repositioning opportunities; . overseeing capital expenditure budgets and forecasts; . assessing return on investment expenditure opportunities; and . analyzing competitive supply conditions in each market. In September 1999, our board of directors approved the repurchase, from time to time on the open market and/or in privately negotiated transactions, of up to 22 million of the outstanding shares of our common stock, operating partnership units or preferred securities convertible into a like number of shares of common stock. Through March 2000, we spent, in the aggregate, approximately $150 million, $62 million of which we spent in the first three months of 2000, on repurchases for a total reduction of 16.2 million equivalent shares on a fully diluted basis. We have not made any repurchases since that time, but will continue to evaluate the stock repurchase program based on changes in market conditions and the stock price. The REIT Conversion and Other Related Transactions During 1998, Host Marriott and its subsidiaries and affiliates consummated a series of transactions intended to enable us to qualify as a REIT for federal income tax purposes. As a result of these transactions, the hotels formerly owned by Host Marriott and its subsidiaries and other affiliates are now owned by the operating partnership and its subsidiaries; the operating partnership and its subsidiaries leased substantially all of these hotels to Crestline Capital Corporation, and Marriott International and other hotel operators conducted the day to day management of the hotels pursuant to management agreements with Crestline. We have elected to be treated as a REIT for federal income tax purposes effective January 1, 1999. The important transactions comprising the REIT conversion are summarized below. S-35

As discussed above during 1998, Host Marriott reorganized its hotels and certain other assets so that they were owned by the operating partnership and its subsidiaries. Host Marriott and its subsidiaries received a number of units of the operating partnership equal to the number of then outstanding shares of Host Marriott common stock, and the operating partnership and its subsidiaries assumed substantially all of the liabilities of Host Marriott and its subsidiaries. As a result of this reorganization and the related transactions described below, we are the sole general partner in the operating partnership and as of September 8, 2000 held approximately 78% of the outstanding units of the operating partnership. The operating partnership and its subsidiaries conduct our hotel ownership business. Units of the operating partnership owned by holders other than us are redeemable at the option of the holder, generally commencing one year after the issuance of their units of the operating partnership. Upon redemption of a unit of the operating partnership, the holder would receive from the operating partnership cash in an amount equal to the market value of one share of our common stock. However, in lieu of a cash redemption by the operating partnership, we have the right to acquire any unit of the operating partnership offered for redemption directly from the holder thereof in exchange for either one share of our common stock or cash in an amount equal to the market value of one share of our common stock. On February 7, 2001, we issued to the Blackstone Entities 12.5 million shares of our common stock upon surrender of 12.5 million units of the operating partnership for redemption. As a result, our ownership of the operating partnership increased from 78% to approximately 82%. The Blackstone Entities immediately sold these shares in an underwritten public offering. In connection with the REIT conversion, two taxable corporations, Rockledge Hotel Properties and Fernwood Hotel Assets, were formed in which the operating partnership owns approximately 95% of the economic interest but none of the voting interest. We refer to these two subsidiaries as the non-controlled subsidiaries. The non-controlled subsidiaries hold various assets which were originally contributed by Host Marriott and its subsidiaries to the operating partnership, but whose direct ownership by the operating partnership or its other subsidiaries generally would jeopardize our status as a REIT and the operating partnership's status as a partnership for federal income tax purposes. These assets primarily consist of interests in partnerships or other interests in three hotels which are not leased, and specified furniture, fixtures and equipment--also known as FF&E--used in the hotels. For example, Rockledge Hotel Properties owns approximately a 50% non-controlling interest in the CBM Joint Venture which owns 120 Courtyard by Marriott properties. The operating partnership has no control over the operation or management of the hotels or other assets owned by the non-controlled subsidiaries. The Host Marriott Statutory Employee/Charitable Trust acquired all of the voting common stock of each non-controlled subsidiary, representing, in each case, the remaining approximately 5% of the total economic interests in each non- controlled subsidiary. The beneficiaries of the Employee/Charitable Trust are (1) a trust formed for the benefit of specified employees of the operating partnership and (2) the J. Willard and Alice S. Marriott Foundation. Effective January 1, 2001, we are able to own all of the voting stock of the non- controlled subsidiaries without adversely affecting our REIT status so long as they elect to be taxable REIT subsidiaries. We are considering pursuing a transaction with the Host Marriott Statutory Employee/Charitable Trust that would allow us to acquire control of the non-controlled subsidiaries, although we have not reached any such agreement and cannot assure you that any such agreement will be reached or that a transaction will be consummated. Whether or not such an agreement is reached, effective January 1, 2001, each of the non- controlled subsidiaries will elect to be treated as a taxable REIT subsidiary. In December 1999, the REIT Modernization Act was enacted (with most provisions effective for taxable years beginning after December 31, 2000), which significantly amends the REIT laws applicable to us. Under the applicable sections of the Internal Revenue Code, as amended by the REIT Modernization Act, and the corresponding regulations that govern the federal income tax treatment of REITs and their shareholders, a REIT must meet certain tests regarding the nature of its income and assets, as described, in part, below and in more detail under "Federal Income Tax Considerations". Prior to the enactment of the REIT Modernization Act, REITs were restricted in their ability to derive revenues directly from the operation of hotels. However, they were permitted to derive rental income by leasing hotels. Therefore, the operating partnership and its subsidiaries leased virtually all of their hotel properties to third party lessees during 1999 and 2000, primarily Crestline and its subsidiaries. Beginning January 1, 2001, a S-36

REIT is permitted to own up to 100% of the voting stock of one or more taxable REIT subsidiaries subject to limitations on the value of those subsidiaries. Rents received from such subsidiaries will not be disqualified from being "rents from real property" by reason of the REIT's (or, in our case, the operating partnership's) ownership interest in the subsidiary so long as the properties are operated on behalf of the taxable REIT subsidiary by an "eligible independent contractor." This enables the operating partnership to lease its hotels to wholly owned taxable REIT subsidiaries if the hotels are operated and managed on behalf of such subsidiaries by an independent third party. Under the REIT Modernization Act, taxable REIT subsidiaries are subject to federal income tax. As a result of the passage of the REIT Modernization Act, effective January 1, 2001, HMT Lessee acquired the equity interests in the lessees of 112 of our full-service hotels and the leasehold interests in four of our full-service hotels from Crestline. In connection with this acquisition, our non-competition agreement with Crestline relating to activities with respect to senior living communities was terminated effective January 1, 2001. For a description of the acquisition of the leasehold interests from Crestline, see "Recent Developments". Hotel Lodging Industry The lodging industry posted moderate gains in the First Three Quarters 2000 and Full Year 1999 as higher average daily rates drove strong increases in REVPAR, which measures daily room revenues generated on a per room basis. This does not include food and beverage or other ancillary revenues generated by the property. REVPAR represents the product of the average daily room rate charged and the average daily occupancy achieved. Previously, the upper-upscale sector of the lodging industry benefited from a favorable supply/demand imbalance, driven in part by low construction levels combined with high gross domestic product, or GDP, growth. However, during 1998 through First Three Quarters 2000 supply moderately outpaced demand, causing slight declines in occupancy rates in the sector in which we operate. According to Smith Travel Research, supply in our brands' competitive set consisting of Crowne Plaza; Doubletree; Hyatt; Hilton; Radisson; Renaissance; Sheraton; Westin; and Wyndham increased 1.5% and 1.1% for the years ended December 31, 1999 and 1998, respectively, while demand in our competitive set increased 0.9% and decreased 0.9% for the same periods, respectively. During the First Three Quarters 2000, demand in our competitive set increased 4.6%, moderately exceeding supply growth of 2.0%. At the same time, occupancy increased 2.6% in our competitive set for the First Three Quarters 2000 versus the same period one year ago. The current amount of excess supply growth in the upper-upscale and luxury portions of the full-service segments of the lodging industry is beginning to moderate and has been much less severe than that experienced in the lodging industry in other economic downturns, in part because of the greater financial discipline and lending practices imposed by financial institutions and public markets today relative to those during the late 1980's. Our hotels have outperformed both the industry as a whole and the upper- upscale and luxury full-service segments. The attractive locations of our hotels, the limited availability of new building sites for new construction of competing full service hotels, and the lack of availability of financing for new full service hotels has allowed us to maintain REVPAR and average daily rate premiums over our competitors in these service segments. For our comparable properties as defined on page S-33, the increase in average daily rate premiums helped generate a strong increase in REVPAR of 6.6% for the First Three Quarters. Furthermore, because our lodging operations have a high fixed- cost component, increases in REVPAR generally yield greater percentage increases in our earnings and cash flows. As a result of HMT Lessee's acquisition of the leasehold interests from Crestline with respect to 116 of our full-service hotels, any change in earnings and cash flow levels at those properties will have a direct effect on our consolidated earnings and cash flows. The relative balance between supply and demand growth may be influenced by a number of factors including growth of the economy, interest rates, unique local considerations and the relatively long lead time to develop urban, convention and resort hotels. We believe that growth in room supply in the upper-upscale sector S-37

in which we operate will continue to exceed growth in room demand through 2001. However, we believe that during 2001 and 2002 supply growth will begin to decrease as the lack of availability of development financing slows new construction. We believe that demand growth will begin to increase during 2001 and 2002. However, some economists are predicting an economic slowdown in 2001, which could lead to substantial decreases in demand. There can be no assurance that growth in supply will decrease, that growth in demand will increase or that REVPAR and earnings and cash flows will continue to improve. Hotel Lodging Properties Our lodging portfolio, as of February 1, 2001, consists of 122 upscale and luxury full-service hotels containing approximately 58,000 rooms. Our hotel lodging properties represent quality upscale and luxury assets in the full service segment. Our hotel properties are currently operated under various premium brands including Marriott, Ritz-Carlton, Four Seasons, Hilton, Hyatt and Swissotel. Our hotels average approximately 478 rooms. Thirteen of our hotels have more than 750 rooms. Hotel facilities typically include meeting and banquet facilities, a variety of restaurants and lounges, swimming pools, gift shops and parking facilities. Our hotels primarily serve business and pleasure travelers and group meetings at locations in urban, airport, resort/convention and suburban locations throughout the United States. The properties are generally well situated in locations where there are significant barriers to entry by competitors including downtown areas of major metropolitan cities, at airports and resort/convention locations where there are limited or no development sites. The average age of the properties is 16.7 years, although many of the properties have had substantial renovations or major additions. To maintain the overall quality of our lodging properties, each property undergoes refurbishments and capital improvements on a regularly scheduled basis. Typically, refurbishing has been provided at intervals of five years, based on an annual review of the condition of each property. For fiscal years 1998, 1999 and First Three Quarters 2000 we spent $165 million, $197 million and $155 million, respectively, on capital improvements to existing properties. As a result of these expenditures, we expect to maintain high quality rooms, restaurants and meeting facilities at our properties. In addition to acquiring and maintaining superior assets, a key part of our strategy is to have the hotels managed by leading management companies. As of February 1, 2001, 100 of our 122 hotel properties were managed by subsidiaries of Marriott International as Marriott or Ritz-Carlton brand hotels and an additional nine hotels are part of Marriott International's full-service hotel system through franchise agreements. The remaining hotels are managed by leading management companies including Four Seasons, Hilton and Hyatt. Our properties have reported annual increases in REVPAR since 1993. Based upon data provided by Smith Travel Research, our comparable properties, as previously defined, have more than a 7 and 10 percentage point occupancy premium and an approximate 30% and 32% REVPAR premium over the competitive set for First Three Quarters 2000 and fiscal year 1999, respectively.

(2) The property statistics and operating results include operations for the five hotels which were sold at various times throughout 1999, through the date of sale. During 2000, in connection with the Courtyard Settlement described under "Recent Developments", the CBM Joint Venture, which was formed by our non- controlled subsidiary, Rockledge Hotel Properties, and Marriott International and their affiliates, acquired the partnership interests in Courtyard by Marriott Limited Partnership and Courtyard by Marriott II Limited Partnership, which collectively own 120 Courtyard by Marriott limited-service properties totaling 17,554 rooms. Rockledge Hotel Properties owns approximately a 50% non- controlling interest in the CBM Joint Venture. These properties have had a significant increase in operations in 2000 and we expect that they will have a positive impact on our earnings in 2001. However, there can be no assurance that they will have a positive impact on our earnings. S-40

The following table sets forth as of February 1, 2001, the location and number of rooms of each of our 122 full-service hotels. As of February 1, 2001, all of the properties are leased to HMT Lessee and operated under Marriott brands by Marriott International, unless otherwise indicated.

(2) This property is not wholly owned by the operating partnership. (3) This property is not leased to HMT Lessee. Investments in Affiliated Partnerships We also maintain investments in several partnerships that own hotel properties. Typically, the operating partnership and certain of its subsidiaries manage our partnership investments and through a combination of general and limited partnership interests, conduct the partnership services business. As previously discussed, in connection with the REIT conversion, Rockledge Hotel Properties and Fernwood Hotel Assets were formed as non- controlled subsidiaries to hold various assets, the direct ownership of which by us or the operating partnership could jeopardize our status as a REIT or the operating partnership's treatment as a partnership for federal income tax purposes. As of December 31, 2000, substantially all of our general and limited partner interests in partnerships owning 208 limited-service properties (including nearly all of our interests in the CBM Joint Venture) were held by our two non-controlled subsidiaries. S-42

The partnership hotels are currently operated under management agreements with Marriott International or its subsidiaries. As the general partner, we oversee and monitor Marriott International and its subsidiaries' performance pursuant to these agreements. Additionally, we are responsible for the payment of partnership obligations from partnership funds, preparation of financial reports and tax returns and communications with lenders, limited partners and regulatory bodies. As the general partner, we are reimbursed for the cost of providing these services subject to limitations in certain cases. Cash distributions provided from these partnerships are tied to the overall performance of the underlying properties and the overall level of debt. There were no distributions in the First Three Quarters 2000 and Full Year 1999. Distributions from these partnerships to us were $2 million in 1998. All debt of these partnerships is nonrecourse to us and our subsidiaries, except that we are contingently liable under various guarantees of debt obligations of certain of the limited-service partnerships. Marketing As of February 1, 2001, 100 of our 122 hotel properties are managed by subsidiaries of Marriott International as Marriott or Ritz-Carlton brand hotels and an additional nine hotels are part of Marriott International's full-service hotel system through franchise agreements. The remaining hotels are managed primarily by Four Seasons, Hilton, Hyatt and Swissotel. We believe that our properties will continue to enjoy competitive advantages arising from their participation in the Marriott, Ritz-Carlton, Four Seasons, Hilton, Hyatt and Swissotel hotel systems. The national marketing programs and reservation systems of each of these managers, as well as the advantages of strong customer preference for these upper-upscale and luxury brands should also help these properties to maintain or increase their premium over competitors in both occupancy and room rates. Repeat guest business is enhanced by guest rewards programs offered by Marriott, Ritz-Carlton, Hilton, Hyatt and Swissotel. Each of the managers maintains national reservation systems that provide reservation agents with complete descriptions of the rooms available and up-to-date rate information from the properties. Our website (www.hostmarriott.com) currently permits users to connect to the Marriott, Ritz-Carlton, Four Seasons, Hilton, Hyatt, and Swissotel reservation systems to reserve rooms in our hotels. Our website is not a part of this prospectus supplement or the accompanying prospectus. Competition Our hotels compete with several other major lodging brands in each segment in which they operate. Competition in the industry is based primarily on the level of service, quality of accommodations, convenience of locations and room rates. Although the competitive position of each of our hotel properties differs from market to market, we believe that our properties compare favorably to their competitive set in the markets in which they operate on the basis of these factors. The following table presents key participants in segments of the lodging industry in which we compete: Segment Representative Participants - ------- --------------------------- Luxury Full-Service Ritz-Carlton; Four Seasons Upscale Full-Service Crown Plaza; Doubletree; Hyatt; Hilton; Marriott Hotels, Resort and Suites; Radisson; Renaissance; Sheraton; Swissotel; Westin; Wyndham Seasonality Our individual hotel revenues have traditionally experienced significant seasonality. However, this is mitigated to some extent by the geographic diversity of our hotels. In addition, hotel revenues in the fourth quarter S-43

reflect sixteen weeks of results compared to twelve weeks for the first three quarters of the fiscal year. Average hotel sales by quarter over the three years 1997 through 1999 for our lodging properties are as follows: First Quarter Second Quarter Third Quarter Fourth Quarter ------------- -------------- ------------- -------------- 22% 23% 22% 33% Legal Proceedings Tampa Waterside Hotel. On January 23, 2001, Tampa Convention Hotel Associates, Inc. ("TCHA") filed a lawsuit, Tampa Convention Hotel Associates, Inc. v. The City of Tampa, Florida, et al., Case No. 01000668, Division G, in the Circuit Court for Hillsborough County, Florida against the City of Tampa (the "City"), Faison & Associates 2000, L.L.C. ("Faison"), Sodexho Marriott Services, Inc., f/k/a Marriott International, Inc. ("Marriott International"), Host Marriott, and HMC Hotel Development LLC ("HMC Development"). TCHA was one of several groups who had submitted development proposals in response to the City's 1995 request for a proposal ("RFP") to develop a convention center hotel in downtown Tampa. Each of the proposals submitted was ranked under the terms of the RFP. The City's Hotel Review Committee ranked the TCHA proposal second, and commenced negotiations with the top-ranked bidder ("Faison/Sheraton"). Faison/Sheraton failed to fulfill certain contingencies by a May 27, 1997 deadline and the parties terminated their negotiations. TCHA alleges that it relied on the May 27, 1997 deadline, and that the City engaged in negotiations with other bidders prior to its expiration to the detriment of TCHA. On May 29, 1997, the City cancelled the RFP. HMC Development subsequently entered into development agreements with the City to develop the convention center hotel in October of 1997, and closed on the Tampa hotel site in January of 1998. TCHA is suing the City on promissory estoppel grounds for failing to comply with the Florida Sunshine Law by conducting private negotiations with the other defendants. TCHA alleges that the other defendants tortiously interfered with its business relationship with the City. TCHA is seeking unspecified actual, compensatory, and special damages. All of the defendants have filed motions to dismiss this lawsuit. A hearing on these motions has not yet been set. We believe all of the lawsuits in which we are a defendant are without merit and we are vigorously defending against such claims. For information on additional legal proceedings affecting our business, please refer to our Quarterly Report on Form 10-Q for the quarter ended September 8, 2000 (filed on October 23, 2000), which is incorporated by reference into the accompanying prospectus.

DESCRIPTION OF THE CLASS C PREFERRED STOCK This description of material terms of the 10% Class C Cumulative Redeemable Preferred Stock, par value $.01 per share, offered hereby supplements, and to the extent inconsistent therewith or as expressly provided herein replaces, the description of certain general terms and provisions of our preferred stock, par value $.01 per share, set forth in the accompanying prospectus. As used under this caption "Description of the Class C Preferred Stock" and in the accompanying prospectus under "Description of Preferred Stock", all references to "Host Marriott" or the "company" mean Host Marriott Corporation, excluding, unless otherwise expressly stated or the context otherwise requires, our subsidiaries. The following summary of material terms of the Class C preferred stock does not purport to be complete and is subject to and qualified in its entirety by reference to all of the provisions of our Articles of Amendment and Restatement of Articles of Incorporation--which we refer to as our Charter--and the form of articles supplementary relating to the Class C preferred stock, all of which have been or will be filed as exhibits to or incorporated by reference in the registration statement of which the accompanying prospectus is a part. You may obtain copies of these documents in the manner described under "Where You Can Find More Information". Prospective investors should carefully review the information in the accompanying prospectus under "Restrictions on Ownership and Transfer" for important information concerning the restrictions on ownership and transfer applicable to the Class C preferred stock. General Our Charter provides that the total number of shares of stock, which we refer to as capital stock, of all classes which we are authorized to issue is 800,000,000, 750,000,000 of which initially were classified as common stock, par value $.01 per share, and 50,000,000 of which initially were classified as preferred stock, par value $.01 per share. Currently, 750,000,000 shares are classified as common stock, 50,000,000 shares are classified as preferred stock, 4,600,000 shares of which are classified as Class A Cumulative Redeemable Preferred Stock, par value $.01 per share, 4,600,000 shares of which are classified as Class B Cumulative Redeemable Preferred Stock, par value $.01 per share, and 650,000 shares of which are classified as Series A Junior Participating Preferred Stock, par value $.01 per share. Under our Charter, our board of directors is authorized, without a vote of the stockholders, to classify or reclassify any unissued shares of capital stock by setting or changing the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends, qualifications or terms or conditions of redemption of such shares of capital stock. The board of directors also has the power to classify or reclassify any unissued shares of capital stock (including shares initially classified as common stock or preferred stock) into any other class or series of capital stock, and to divide and classify shares of any class into one or more series of such class. Thus, the board of directors could authorize the issuance of a class or series of capital stock with terms and conditions which could have the effect of delaying, deferring or preventing a transaction or a change in control of Host Marriott that might involve a premium price for holders of shares of common stock, Class A preferred stock, Class B preferred stock or Class C preferred stock or otherwise be in their respective best interests. We have previously authorized the issuance of shares of Class A preferred stock and Class B preferred stock. As of the date of this prospectus supplement, there were 4,160,000 shares of Class A preferred stock and 4,000,000 shares of Class B preferred stock issued and outstanding. We have previously authorized the issuance of shares of Series A junior preferred stock in connection with our stockholder rights plan. As of the date of this prospectus supplement, no shares of Series A junior preferred stock were outstanding, although we have reserved for issuance 650,000 shares of Series A junior preferred stock. For a description of our stockholder rights plan, see the accompanying prospectus under "Description of Common Stock--Stockholder Rights Plan/Preferred Stock Purchase Rights". We have authorized the issuance of a class of preferred stock, consisting of 5,200,000 shares, plus up to an additional 780,000 shares issuable upon exercise of the underwriters' over-allotment option, designated as the 10% Class C Cumulative Redeemable Preferred Stock. S-45

The Class C preferred stock has been approved for listing on the New York Stock Exchange under the symbol "HMTPrC", subject to notice of official issuance. We expect that trading of the Class C preferred stock on the NYSE will commence within 30 days after the initial delivery of the Class C preferred stock. The Class C preferred stock does not contain any provisions affording holders of the Class C preferred stock protection in the event of a highly leveraged or other transaction that might adversely affect holders of the Class C preferred stock, except to the limited extent described below under "--Voting Rights". The transfer agent, registrar and paying agent for the Class C preferred stock will be First Chicago Trust Company of New York. The articles supplementary for the Class C preferred stock will provide that we will at all times maintain an office or agency in the Borough of Manhattan, The City of New York, where shares of Class C preferred stock may be surrendered for payment (including upon redemption, if any), registration of transfer or exchange. The certificates evidencing the Class C preferred stock will initially be issued in the form of temporary certificates. Holders of temporary certificates will be entitled to exchange them for definitive certificates as soon as definitive certificates are available, which we anticipate will be within 150 days after the original issuance of the Class C preferred stock. Ranking The Class C preferred stock will rank, with respect to the payment of dividends and the distribution of assets upon our liquidation, dissolution or winding up: (1) senior to our common stock, senior to our Series A junior preferred stock, and senior to any other class or series of our capital stock other than capital stock referred to in clauses (2) and (3) of this sentence; (2) on a parity with our Class A preferred stock and Class B preferred stock and on a parity with any class or series of our capital stock the terms of which specifically provide that such class or series of capital stock ranks on a parity with the Class C preferred stock as to the payment of dividends and the distribution of assets upon our liquidation, dissolution or winding up; and (3) junior to any class or series of our capital stock the terms of which specifically provide that such class or series of capital stock ranks senior to the Class C preferred stock as to the payment of dividends and the distribution of assets upon our liquidation, dissolution or winding up. The term "capital stock" does not include convertible debt securities. The description of the ranking of the Class C preferred stock set forth in this paragraph supersedes and replaces, insofar as it concerns the Class C preferred stock, the discussion set forth in the accompanying prospectus under "Description of Preferred Stock--Rank". Our board of directors may, from time to time, without stockholder approval, authorize the issuance of one or more additional classes or series of capital stock ranking on a parity with the Class C preferred stock. See "--General" above and "--Voting Rights" below. In addition, with the affirmative vote or consent of the holders of at least two-thirds of the shares of Class C preferred stock outstanding at the time, as described below under "--Voting Rights", we may issue one or more classes or series of capital stock which rank senior to the Class C preferred stock as to the payment of dividends and/or the distribution of assets upon our liquidation, dissolution or winding up, and the rights of holders of Class C preferred stock to receive dividends and amounts due upon our liquidation, dissolution or winding up will be subject to the preferential rights of any such senior class or series of our capital stock. However, no such senior capital stock is currently outstanding. In addition, because our operations are conducted primarily through the operating partnership and its subsidiaries, our cash flow and our consequent ability to pay dividends on our capital stock (including the payment of dividends to holders of the Class C preferred stock) are dependent upon the results of operations of those subsidiaries and the distribution of monies by those subsidiaries to us. Dividend and Redemption Restrictions Under Debt Instruments We and our subsidiaries are, and may in the future become, parties to agreements and instruments which restrict or prevent the payment of dividends on, or the purchase or redemption of, Class C preferred stock and S-46

any other class or series of our capital stock, including indirect restrictions (for example, through covenants requiring maintenance of specified levels of net worth) and direct restrictions. The operating partnership's credit facility, to which we are a party, provides that distributions may only be paid to holders of equity interests of the operating partnership, including Host Marriott as a partner of the operating partnership, and we may only pay dividends on our capital stock, including the Class C preferred stock, so long as (1) no default or event of default under the credit facility exists at the time of the payment or would exist immediately after giving effect to such payment and (2) we qualify or have taken all actions necessary to qualify as a REIT for federal income tax purposes. Assuming the foregoing conditions are met, during any four consecutive fiscal quarters, the operating partnership may distribute to us and the other holders of the units of the operating partnership, and we may pay dividends to our shareholders (including the payment of dividends to holders of the Class C preferred stock), in an amount not to exceed the greater of (A) 85% of our adjusted funds from operations (as defined in the credit facility) for those four consecutive fiscal quarters and (B) the minimum amount necessary for us to maintain our status as a REIT for federal income tax purposes. In addition, the indenture governing the operating partnership's outstanding senior debt provides that no distributions may be made to holders of its equity interests, including Host Marriott as a partner of the operating partnership, (1) during the continuance of defaults or events of defaults under the indenture, (2) if the operating partnership could not incur at least $1.00 of indebtedness (as defined) under the terms of the indebtedness covenant of the indenture or (3) if all restricted payments (as defined) made since the issue date of the debt securities generally exceed the sum of (a) 95% of the aggregate funds from operations (as defined) beginning on the first day of the fiscal quarter in which the relevant debt securities were issued, (b) 100% of the net cash proceeds from the permitted issuance of certain equity interests of the operating partnership and from the issuance of specified convertible indebtedness upon conversion thereof, or otherwise received as capital contributions (as defined), (c) the total net reduction in certain investments resulting from payments to the operating partnership or the sale of those investments, (d) the fair market value of noncash tangible assets or capital stock (other than that of the operating partnership or Host Marriott) acquired in exchange for qualified capital stock (as defined), and (e) fair market value of noncash tangible assets or capital stock (other than that of the operating partnership or Host Marriott) contributed to the operating partnership as a capital contribution (as defined). However, notwithstanding the foregoing restrictions on distributions by the operating partnership, it may make distributions as required to allow us to make all dividend payments necessary to maintain our status as a REIT for federal income tax purposes unless (1) it is during the continuance of a default or event of default under the indenture or (2) the aggregate principal amount of all outstanding debt of the operating partnership and its restricted subsidiaries (as defined) other than specified convertible indebtedness at such time is equal to or greater than 80% of the value of the operating partnership's adjusted total assets (as defined). In the event of a deterioration in our financial condition or results of operations or the financial condition or results of operations of our subsidiaries, the terms of the debt instruments or agreements to which we or our subsidiaries are, or in the future may become, parties could limit or prohibit the payment of dividends on shares of Class C preferred stock and any other class or series of our capital stock. Our failure to pay dividends as required by the Internal Revenue Code, whether as a result of restrictive covenants in debt instruments or otherwise, would result in the loss of our status as a REIT for federal income tax purposes. As described in "Risk Factors--Adverse consequences of our failure to qualify as a REIT", this loss of our status as a REIT would likely have a material adverse effect on us. Dividends Subject to the preferential rights of holders of any class or series of our capital stock ranking senior to the Class C preferred stock as to dividends, holders of the Class C preferred stock will be entitled to receive, when, as and if authorized by our board of directors and declared by us, out of our funds legally available for the payment of dividends, cumulative cash dividends at the rate of 10% per annum of the $25.00 per share liquidation preference (equivalent to an annual rate of $2.50 per share). Dividends will accrue and be cumulative from the first date on which any shares of Class C preferred stock are originally issued and will be S-47

payable quarterly in arrears on January 15, April 15, July 15 and October 15 of each year or, if such day is not a Business Day, as defined in the articles supplementary for the Class C preferred stock, the next succeeding Business Day. The first dividend, which will be payable on April 15, 2001 (or, if such day is not a Business Day, on the next succeeding Business Day), will be for less than a full quarterly dividend period. Dividends payable on the Class C preferred stock, including dividends payable for partial dividend periods, will be computed on the basis of a 360-day year consisting of twelve 30-day months. Dividends will be payable to holders of record as they appear in our stock transfer books at the close of business on the applicable dividend record date, which will be the 1st day of the calendar month in which the applicable dividend payment date falls or such other date designated by our board of directors that is not more than 30 nor less than ten days prior to such dividend payment date. If any dividend payment date or redemption date for the Class C preferred stock falls on a day which is not a Business Day, the payment which would otherwise be due on such dividend payment date or redemption date, as the case may be, may be made on the next succeeding Business Day with the same force and effect as if made on such dividend payment date or redemption date, as the case may be, and no interest or additional dividends or other sum will accrue on the amount so payable for the period from and after such dividend payment date or redemption date, as the case may be, to such next succeeding Business Day. If any shares of Class C preferred stock are outstanding, no full dividends will be declared or paid or set apart for payment on any shares of our capital stock of any other class or series ranking, as to dividends, on a parity with, or junior to, the Class C preferred stock for any period unless full cumulative dividends have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for such payment on the Class C preferred stock for all past dividend periods (including, without limitation, any dividend period that terminates on any date upon which dividends on such other class or series of our capital stock are declared or paid or set apart for payment, as the case may be). When such cumulative dividends are not paid in full, or a sum sufficient for such full payment is not so set apart, upon the Class C preferred stock and the shares of any other class or series of our capital stock ranking on a parity as to dividends with the Class C preferred stock, all dividends declared upon the Class C preferred stock and any other class or series of our capital stock ranking on a parity as to dividends with the Class C preferred stock shall be declared pro rata so that the amount of dividends declared per share of Class C preferred stock and such other class or series of our capital stock shall in all cases bear to each other the same ratio that accrued and unpaid dividends per share on the Class C preferred stock and such other class or series of capital stock, which will not include any accrual in respect of unpaid dividends for prior dividend periods if the other class or series of capital stock does not provide for cumulative dividends, bear to each other. Except as provided in the immediately preceding paragraph, unless full cumulative dividends on the Class C preferred stock have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for payment for all past dividend periods (including, without limitation, any dividend period that terminates on a date that also is a Subject Date (as defined below)), then . no dividends, other than in common stock or shares of any other class or series of our capital stock ranking junior to the Class C preferred stock as to dividends and as to the distribution of assets upon our liquidation, dissolution or winding up, shall be declared or paid or set aside for payment and no other distribution shall be declared or made upon our common stock or any other class or series of our capital stock ranking junior to or on a parity with the Class C preferred stock as to dividends or as to the distribution of assets upon our liquidation, dissolution or winding up, and . no common stock, or shares of any other class or series of our capital stock ranking junior to or on parity with the Class C preferred stock as to dividends or as to the distribution of assets upon our liquidation, dissolution or winding up, shall be redeemed, purchased or otherwise acquired for any consideration or any money paid to or made available for a sinking fund for the redemption of any such shares by us, (1) except by conversion into or exchange for shares of any other class or series of our capital stock ranking junior to the shares of Class C preferred stock as to dividends and as to the distributions of assets upon our liquidation, dissolution or winding up and (2) except for the redemption, S-48

purchase or acquisition by us of our capital stock of any class or series in order to preserve our status as a REIT for federal income tax purposes or the operating partnership's status as a partnership for federal income tax purposes. As used in this paragraph, the term "Subject Date" means (1) any date on which any dividends are declared or paid or set apart for payment or other distribution declared or made upon our common stock or any other class or series of our capital stock ranking junior to or on a parity with the Class C preferred stock as to dividends or as to the distribution of assets upon our liquidation, dissolution or winding up, and (2) any date on which any shares of our common stock or any other class or series of our capital stock ranking junior to or on a parity with the Class C preferred stock as to dividends or as to the distribution of assets upon our liquidation, dissolution or winding up are redeemed, purchased or otherwise acquired for any consideration or any money paid to or made available for a sinking fund for the redemption of any such shares by us. Our Charter provides that our ability to pay dividends on any class or series of our capital stock is not limited by the amount that would be needed, if we were to be dissolved at the time of the dividend, to satisfy the preferential rights upon our liquidation, dissolution or winding up of classes or series of capital stock ranking senior to the capital stock receiving the dividends, unless otherwise specifically provided for in the terms of any class or series of capital stock. The terms of the Class C preferred stock do not provide otherwise and, accordingly, the Class C preferred stock will be subject to the foregoing provisions. No dividends on any shares of Class C preferred stock will be declared or paid or set apart for payment at such time as any agreement, including any agreement relating to our indebtedness, prohibits such declaration, payment or setting apart for payment or provides that such declaration, payment or setting apart for payment would constitute a breach thereof or a default thereunder, or if such declaration, payment or setting apart for payment will be restricted or prohibited by applicable law. Notwithstanding the foregoing, dividends on the Class C preferred stock will accrue regardless of whether or not we have earnings, regardless of whether or not there are funds legally available for the payment of such dividends, and regardless of whether or not such dividends are declared. No interest, or sum of money in lieu of interest, will be payable in respect of any dividend payment or payments on the Class C preferred stock that may be in arrears, and holders of the Class C preferred stock will not be entitled to any dividends, whether payable in cash, securities or other property, in excess of the full cumulative dividends described above. Any dividend payment made on the Class C preferred stock will first be credited against the earliest accrued but unpaid dividend due with respect to the Class C preferred stock. If for any taxable year, we elect to designate as "capital gain dividends", as defined in the Internal Revenue Code, any portion of the dividends paid or made available for the year to holders of all classes and series of our capital stock, then the portion of the dividends designated as capital gain dividends that will be allocable to the holders of the Class C preferred stock will be an amount equal to the total capital gain dividends multiplied by a fraction, the numerator of which will be the total dividends, within the meaning of the Internal Revenue Code, paid or made available to the holders of the Class C preferred stock for the year, and the denominator of which will be the total dividends paid or made available to holders of all classes and series of our capital stock for that year. Information contained under this caption "Dividends" supersedes and replaces, insofar as it concerns the Class C preferred stock, the discussion set forth in the accompanying prospectus under "Description of Preferred Stock--Distributions". Liquidation Preference Upon any voluntary or involuntary liquidation, dissolution or winding up of the company, then, before any distribution or payment will be made to the holders of any common stock or any other class or series of our capital stock ranking junior to the Class C preferred stock as to the distribution of assets upon the liquidation, S-49

dissolution or winding up of the company, but subject to the preferential rights of the holders of any other class or series of our capital stock ranking senior to the Class C preferred stock as to such distribution of assets, the holders of Class C preferred stock will be entitled to receive and to be paid out of our assets legally available for distribution to stockholders liquidating distributions in the amount of $25.00 per share, plus an amount equal to all accrued and unpaid dividends to, but not including, the date of payment. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of shares of Class C preferred stock, as such, will have no right or claim to any of our remaining assets. If, upon any such voluntary or involuntary liquidation, dissolution or winding up, our assets legally available for distribution to stockholders are insufficient to pay the full amount of the liquidating distributions on all outstanding shares of Class C preferred stock and the full amount of the liquidating distributions payable on all shares of any other classes or series of our capital stock ranking on a parity with the Class C preferred stock as to the distribution of assets upon our liquidation, dissolution or winding up, then the holders of the Class C preferred stock and all other such classes and series of capital stock will share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled. If liquidating distributions shall have been made in full to all holders of Class C preferred stock and any other classes or series of our capital stock ranking on a parity with the Class C preferred stock as to the distribution of assets upon our liquidation, dissolution or winding up, then our remaining assets will be distributed among the holders of any other classes or series of our capital stock ranking junior to the Class C preferred stock as to the distribution of assets upon our liquidation, dissolution or winding up, according to their respective rights and preferences. For purposes of the two preceding paragraphs, neither the consolidation or merger of the company with or into any other corporation, trust or entity, nor the sale, lease or conveyance of all or substantially all of our property or business, will be deemed to constitute a liquidation, dissolution or winding up of the company. The information contained under this caption "--Liquidation Preference" supersedes and replaces, insofar as it concerns the Class C preferred stock, the discussion set forth in the accompanying prospectus under "Description of Preferred Stock--Liquidation Preference". Optional Redemption The Class C preferred stock is not redeemable prior to March 27, 2006, except that we will be entitled, pursuant to provisions of our Charter, to redeem, repurchase or acquire shares of Class C preferred stock in order to preserve our status as a REIT for federal income tax purposes or the status of the operating partnership as a partnership for federal income tax purposes. For a description of these provisions, see "--Other" below and "Restrictions on Ownership and Transfer" in the accompanying prospectus. On and after March 27, 2006, we may, at our option upon not less than 30 nor more than 60 days' prior written notice to the holders of the Class C preferred stock, redeem the Class C preferred stock, in whole or from time to time in part, for a cash redemption price equal to $25.00 per share plus, except as described below with respect to redemption after a dividend record date and on or prior to the corresponding dividend payment date, accrued and unpaid dividends to, but not including, the date fixed for redemption. Notwithstanding anything to the contrary in this prospectus supplement or in the accompanying prospectus, unless full cumulative dividends on the Class C preferred stock have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for payment for all past dividend periods (including, without limitation, any dividend period that terminates on the date of any redemption of shares of Class C preferred stock referred to below or on the date of any direct or indirect purchase or other acquisition of shares of Class C preferred stock referred to below, as the case may be), then . no shares of Class C preferred stock will be redeemed unless all outstanding shares of Class C preferred stock are simultaneously redeemed; provided, however, that the foregoing will not prevent our redemption, repurchase or acquisition of shares of Class C preferred stock (a) to preserve our status as a S-50

REIT for federal income tax purposes or the status of the operating partnership as a partnership for federal income tax purposes or (b) pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding shares of Class C preferred stock, and . we will not purchase or otherwise acquire directly or indirectly any shares of Class C preferred stock, except by conversion into or exchange for other capital stock ranking junior to the Class C preferred stock as to dividends and with respect to the distribution of assets upon our liquidation dissolution and winding up; provided, however, that the foregoing will not prevent our redemption, purchase or acquisition of shares of Class C preferred stock (a) to preserve our status as a REIT for federal income tax purposes or the status of the operating partnership as a partnership for federal income tax purposes or (b) pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding shares of Class C preferred stock. If fewer than all of the outstanding shares of Class C preferred stock are to be redeemed, the number of shares to be redeemed will be determined by us and the shares to be so redeemed will be selected by us pro rata from the holders of record of the Class C preferred stock in proportion to the number of shares held of record by the holders, as nearly as may be practicable without creating fractional shares, or by lot or by any other equitable method determined by us that will not result in the transfer of any shares of Class C preferred stock to a trust for the benefit of a charitable beneficiary as described in the accompanying prospectus under "Restrictions on Ownership and Transfer". If fewer than all of the shares of Class C preferred stock evidenced by a stock certificate are to be redeemed, we will issue one or more new certificates for the unredeemed shares. We will give notice of redemption by publication in The Wall Street Journal, or if such newspaper is not then published, a newspaper of general circulation in The City of New York, such publication to be made once a week for two successive weeks commencing not less than 30 nor more than 60 days prior to the redemption date. Notice of redemption also will be mailed, not less than 30 nor more than 60 days prior to the applicable redemption date, to each holder of record of shares of Class C preferred stock at the holder's address in our share transfer records. Each such notice shall state: . the redemption price and the redemption date; . the number of shares of Class C preferred stock to be redeemed; . the place or places, which will include a place in the Borough of Manhattan, The City of New York, where the Class C preferred stock is to be surrendered for payment of the redemption price; and . that dividends on the shares of Class C preferred stock to be redeemed will cease to accrue on the applicable redemption date. If fewer than all of the outstanding shares of Class C preferred stock are to be redeemed, the notice mailed to each holder will also specify the number of shares to be redeemed from that holder. No failure to mail or defect in any mailed notice or in the mailing thereof will affect the validity of the proceedings for the redemption of any shares of Class C preferred stock except as to the holder to whom notice was defective or not given. If notice of redemption has been given and if funds necessary for such redemption have been irrevocably set aside in trust for the benefit of the holders of the shares of Class C preferred stock called for redemption, then from and after the date fixed for redemption, dividends will cease to accrue on the shares of Class C preferred stock so called for redemption, such shares of Class C preferred stock will no longer be deemed outstanding, and all rights of the holders of such shares of Class C preferred stock will terminate, except the right to receive the redemption price, including, if applicable, any accrued and unpaid dividends to, but not including, the redemption date. If any redemption date is not a Business Day, then payment of the redemption price may be made on the next Business Day with the same force and effect as if made on the redemption date, and no interest, additional dividends or other sums will accrue on the amount payable from the redemption date to the next Business Day. S-51

The holders of record of shares of Class C preferred stock at the close of business on a dividend record date will be entitled to receive the dividend payable with respect to those shares on the corresponding dividend payment date notwithstanding the redemption of those shares after that dividend record date and on or prior to the dividend payment date or our default in the payment of the dividend due on that payment date. If a redemption date falls after a dividend record date and on or prior to the corresponding dividend payment date, the amount payable upon redemption will not include the dividend payable on that dividend payment date and the full amount of that dividend will instead be paid on the applicable dividend payment date to the holders of record on the corresponding dividend record date. Except as provided in this paragraph and except to the extent that accrued and unpaid dividends are payable as part of the redemption price, we will make no payment or allowance for unpaid dividends, regardless of whether or not in arrears, on shares of Class C preferred stock called for redemption. The Class C preferred stock has no stated maturity and is not subject to any sinking fund or mandatory redemption. The information under this caption "--Optional Redemption" supersedes and replaces, insofar as it concerns the Class C preferred stock, the discussion in the accompanying prospectus under "Description of Preferred Stock--Redemption". Voting Rights Holders of Class C preferred stock will not have any voting rights, except as set forth in the articles supplementary creating the Class C preferred stock which terms are described below or as otherwise from time to time required by law. Whenever dividends on any shares of Class C preferred stock are in arrears for six or more quarterly dividend periods, whether or not consecutive: . The board of directors of the company will be automatically increased by two, if not already increased by two by reason of the election of directors by the holders of any other class or series of our capital stock upon which like voting rights have been conferred and are exercisable and with which the Class C preferred stock is entitled to vote as a class with respect to the election of those two directors, and . the holders of Class C preferred stock, voting together as single class with all other classes or series of our capital stock upon which like voting rights have been conferred and are exercisable and which are entitled to vote as a class with the Class C preferred stock in the election of those two directors, will be entitled to vote for the election of a total of two additional directors at a special meeting called by an officer of the company at the request of holders of record of at least 10% of the outstanding Class C preferred stock or by the holders of any such other class or series of our capital stock, unless such request is received less than 90 days before the date fixed for the next annual or special meeting of our stockholders, in which case the vote will be held at the earlier of the next annual or special meeting of our stockholders, and at each subsequent annual meeting, until all dividends accumulated on the Class C preferred stock for all prior dividend periods and the then current dividend period have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment in full. If and when full cumulative dividends on the Class C preferred stock for all prior dividend periods and the then current dividend period have been paid in full or declared and a sum sufficient for the payment thereof set aside for payment in full, the right of holders of Class C preferred stock to elect those two directors will cease and, unless there are other classes and series of our capital stock upon which like voting rights have been conferred and are exercisable, the term of office of each of the two directors so elected will immediately and automatically terminate. If a special meeting for the election of the additional directors is not called by one of our officers within 30 days after request, then the holders of record of at least 10% of the outstanding shares of Class C preferred S-52

stock may designate a holder of Class C preferred stock to call that meeting at our expense. At all times that the voting rights described above are exercisable, the holders of Class C preferred stock will have access to our stock transfer records. We will pay all costs and expenses of calling and holding any meeting and of electing directors as described above. So long as any shares of Class C preferred stock remain outstanding, we will not, without the affirmative vote or consent of the holders of at least two- thirds of the Class C preferred stock outstanding at the time, given in person or by proxy either in writing or at a meeting, with the Class C preferred stock voting separately as a class, . authorize, create or issue, or increase the authorized or issued amount of, any class or series of our capital stock ranking senior to the Class C preferred stock as to the payment of dividends or the distribution of assets upon our liquidation, dissolution or winding up, or reclassify any authorized capital stock into such shares, or create, authorize or issue any obligation or security convertible into, exchangeable or exercisable for, or evidencing the right to purchase, any such shares; or . amend, alter or repeal the provisions of our Charter, including, without limitation, the articles supplementary creating the Class C preferred stock, whether by merger, consolidation or otherwise (an "Event"), so as to materially and adversely affect any right, preference, privilege or voting power of the Class C preferred stock or the holders thereof; provided, however, with respect to the occurrence of any Event, so long as shares of Class C preferred stock remain outstanding or are converted into like securities of the surviving entity, in each case with the preferences, rights, privileges, voting powers and other terms thereof materially unchanged, taking into account that upon the occurrence of an Event we may not be the surviving entity and that the surviving entity may be a non-corporate entity, such as a limited liability company, limited partnership or business trust, in which case the Class C preferred stock would be converted into an equity interest, other than capital stock, having preferences, rights, privileges, voting powers and other terms which are materially unchanged from those of the Class C preferred stock, the occurrence of such Event will not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers of the Class C preferred stock or the holders thereof; and provided further that any increase in the amount of authorized preferred stock or common stock or increase in the amount of authorized shares of Class C preferred stock or the creation, issuance or increase in the amount of authorized shares of any other class or series of capital stock, in each case ranking on a parity with or junior to the Class C preferred stock as to dividends and the distribution of assets upon our liquidation, dissolution or winding up, will not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers. The foregoing voting provisions will not apply if, at or prior to the time when the act with respect to which such vote would otherwise be required will be effected, all outstanding shares of Class C preferred stock have been redeemed or called for redemption and sufficient funds will have been deposited in trust to effect such redemption. In any matter in which the Class C preferred stock is entitled to vote, including any action by written consent, each share of Class C preferred will be entitled to one vote, except that when shares of any other class or series of our preferred stock have the right to vote with the Class C preferred stock as a single class on any matter, the Class C preferred stock and the shares of each such other class or series will have one vote for each $25.00 of liquidation preference (excluding accrued dividends). The description of the voting rights set forth above supersedes and replaces, insofar as it concerns the Class C preferred stock, the discussion set forth in the accompanying prospectus under "Description of Preferred Stock--Voting Rights". Other The Class C preferred stock will not be exchangeable for or convertible into any other property or securities of Host Marriott. The Class C preferred stock will not be entitled to any preemptive rights. S-53

Except as expressly stated in the articles supplementary creating the Class C preferred stock or as required by law, the holders of the Class C preferred stock will not have any relative, participating, optional or other special voting rights or powers, and the consent of such holders shall not be required for the taking of any corporate actions. Restrictions on Ownership and Transfer Our Charter contains certain provisions intended to help preserve our status as a REIT for federal income tax purposes and the status of the operating partnership as a partnership for federal income tax purposes. Our board of directors, or a committee thereof, is authorized to take such actions as it deems advisable to refuse to give effect to or to prevent transfers of capital stock which would endanger our status as a REIT or the status of the operating partnership as a partnership. Such actions could include, among other things, redeeming shares of our capital stock, including Class C preferred stock. In the event of any such redemption of Class C preferred stock, the redemption price will be $25.00 per share plus accrued and unpaid dividends unless the redemption date falls after a dividend record date and on or prior to the corresponding dividend payment date, in which case the amount payable upon redemption will not include the dividend payable on that dividend payment date and the full amount of that dividend will instead be paid on the applicable dividend payment date to the holder of record on the corresponding dividend record date. In addition to the above powers of our board of directors, or a committee thereof, other provisions of our Charter which are described in the accompanying prospectus under "Restrictions on Ownership and Transfer" apply irrespective of any action or inaction by the board of directors or a committee thereof. The Class C preferred stock will be subject to such provisions. All certificates representing shares of Class C preferred stock will bear a legend referring to these restrictions. S-54

DESCRIPTION OF COMMON STOCK The disclosure set forth below amends and supplements the section entitled "Description of Common Stock" in the accompanying prospectus. Maryland Unsolicited Takeovers Act The Maryland Unsolicited Takeovers Act applies to any Maryland corporation that is a public reporting company with at least three independent directors. Pursuant to the Maryland Unsolicited Takeovers Act, the board of directors of such a Maryland corporation, without obtaining shareholder approval and notwithstanding a contrary provision in its charter or bylaws, may elect to provide that: (1) the number of directors may be fixed only by a vote of the board of directors; (2) each vacancy on the board of directors (including a vacancy resulting from the removal of a director by the shareholders) may be filled only by the affirmative vote of a majority of the remaining directors in office, even if the remaining directors do not constitute a quorum; and/or (3) any director elected to fill a vacancy shall hold office for the full remainder of the term, rather than until the next election of directors. The Maryland Unsolicited Takeovers Act does not limit the power of a corporation to confer on the holders of any class or series of preferred stock the right to elect one or more directors. Host Marriott has more than three independent directors and therefore our board of directors could elect to provide for any of the foregoing provisions. As of the date of this prospectus supplement, our board of directors has not made any such election. S-55

FEDERAL INCOME TAX CONSIDERATIONS The disclosure set forth below supersedes in its entirety the section entitled "Federal Income Tax Considerations" in the accompanying prospectus. Introduction The following is a summary of the federal income tax considerations anticipated to be material to purchasers of our Class C preferred stock. This summary is based on current law, is for general information only and is not tax advice. Your tax treatment will vary depending on your particular situation and this discussion does not purport to deal with all aspects of taxation that may be relevant to a holder of Class C preferred stock in light of the holder's personal investments or tax circumstances, or to stockholders who receive special treatment under the federal income tax laws. Stockholders receiving special treatment include, without limitation: . insurance companies, . financial institutions or broker-dealers, . tax-exempt organizations, . stockholders holding securities as part of a conversion transaction, or as part of a hedge or hedging transaction or as a position in a straddle for tax purposes, and . foreign corporations or partnerships and persons who are not citizens or residents of the United States. This discussion is also limited to persons who hold the Class C preferred stock as a capital asset (generally property held for investment). In addition, the summary below does not consider the effect of any foreign, state, local or other tax laws that may be applicable to you as a holder of Class C preferred stock. The information in this section is based on: . the Internal Revenue Code, . current, temporary and proposed Treasury Regulations promulgated under the Internal Revenue Code, . the legislative history of the Internal Revenue Code, . current administrative interpretations and practices of the Internal Revenue Service, including its practices and policies as expressed in private letter rulings which are not binding on the Internal Revenue Service except with respect to the particular taxpayers who requested and received such rulings, and . court decisions. in each case as of the date of this prospectus supplement. There is no assurance that future legislation, Treasury Regulations, administrative interpretations and practices or court decisions will not adversely affect existing interpretations. Any change could apply retroactively to transactions preceding the date of the change. We have not requested, and do not plan to request, any rulings from the Internal Revenue Service concerning the tax treatment discussed below, and the statements in this prospectus supplement are not binding on the Internal Revenue Service or a court. Thus, there is no assurance that these statements will not be challenged by the Internal Revenue Service or sustained by a court if challenged by the Internal Revenue Service. The specific tax attributes of a particular shareholder could have a material impact on the tax consequences associated with the purchase, ownership and disposition of the Class C preferred stock. Therefore, it is essential that each prospective shareholder consult with his own tax advisors with regard to the application of the federal income tax laws to such shareholder's personal tax situation, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction. S-56

Federal income taxation of Host Marriott General. Host Marriott made an election to be taxed as a REIT under the Internal Revenue Code, effective for the taxable year beginning January 1, 1999. Host Marriott believes that it is organized and has operated in a manner that will permit it to qualify as a REIT for 1999 and 2000, and we intend to continue to operate as a REIT for future years. No assurance, however, can be given that we in fact will qualify or remain qualified as a REIT. The sections of the Internal Revenue Code and the corresponding regulations that govern the federal income tax treatment of a REIT and its shareholders are highly technical and complex. The following discussion is qualified in its entirety by the applicable Internal Revenue Code provisions, rules and regulations promulgated thereunder, and administrative and judicial interpretations thereof. Hogan & Hartson L.L.P. has provided to us an opinion to the effect that we are organized and have operated in conformity with the requirements for qualification as a REIT, and our intended method of operation will enable us to continue to meet the requirements for qualification and taxation as a REIT under the Internal Revenue Code. It must be emphasized that this opinion is conditioned upon certain assumptions and representations made by Host Marriott and the operating partnership as to factual matters relating to the organization and operation of Host Marriott and its subsidiaries, the operating partnership and its subsidiaries, the non-controlled subsidiaries, taxable REIT subsidiaries after January 1, 2001 (including HMT Lessee), the Host Employee/Charitable Trust and Crestline and its subsidiaries, including the economic and other terms of each lease and the expectations of Host Marriott and the lessees with respect thereto. In addition, this opinion is based upon the factual representations of Host Marriott concerning its business and properties as described in, or incorporated by reference into, this prospectus supplement and the accompanying prospectus. Moreover, qualification and taxation as a REIT depends upon Host Marriott's ability to meet the various qualification tests imposed under the Internal Revenue Code discussed below. Hogan & Hartson L.L.P. will not review Host Marriott's operating results. Accordingly, no assurance can be given that the actual results of Host Marriott's operations for any particular taxable year will satisfy such requirements. Further, the anticipated income tax treatment described below may be changed, perhaps retroactively, by legislative, administrative or judicial action at any time. See "--Failure of Host Marriott to qualify as a REIT" below. If Host Marriott qualifies for taxation as a REIT, it generally will not be subject to federal corporate income taxes on its net income that it currently distributes to its shareholders. This treatment substantially eliminates the "double taxation" at the corporate and shareholder levels that generally results from an investment in a regular corporation. However, Host Marriott will be subject to federal income tax as follows: 1. Host Marriott will be taxed at regular corporate rates on any undistributed "REIT taxable income" including undistributed net capital gains; provided, however, that properly designated undistributed capital gains will effectively avoid taxation at the shareholder level. A REIT's "REIT taxable income" is the otherwise taxable income of the REIT subject to certain adjustments, including a deduction for dividends paid. 2. Under certain circumstances, Host Marriott may be subject to the "alternative minimum tax" due to its items of tax preference and alternative minimum tax adjustments. 3. If Host Marriott has net income from the sale or other disposition of "foreclosure property" which is held primarily for sale to customers in the ordinary course of business or other nonqualifying income from foreclosure property, it will be subject to tax at the highest corporate rate on such income. 4. Host Marriott's net income from "prohibited transactions" will be subject to a 100% tax. In general, "prohibited transactions" are certain sales or other dispositions of property held primarily for sale to customers in the ordinary course of business other than foreclosure property. S-57

5. If Host Marriott fails to satisfy the 75% gross income test or the 95% gross income test discussed below, but nonetheless maintains its qualification as a REIT because certain other requirements are met, it will be subject to a tax equal to (a) the gross income attributable to the greater of (i) the amount by which 75% of its gross income exceeds the amount qualifying under the 75% gross income test described below under "-- Income tests applicable to REITs" and (ii) the amount by which 90% of its gross income exceeds the amount qualifying under the 95% gross income test described below multiplied by (b) a fraction intended to reflect its profitability. 6. If Host Marriott fails to distribute during each calendar year at least the sum of (a) 85% of its REIT ordinary income for such year, (b) 95% of its REIT capital gain net income for such year and (c) any undistributed taxable income from prior periods, Host Marriott will be subject to a 4% excise tax on the excess of such required distribution over the sum of amounts actually distributed and amounts retained but with respect to which federal income tax was paid. 7. If Host Marriott acquires any asset from a taxable "C" corporation in a transaction in which the basis of the asset in the hands of Host Marriott is determined by reference to the basis of the asset in the hands of the "C" corporation, and Host Marriott recognizes gain on the disposition of such asset during the ten-year period beginning on the date on which such asset was acquired by Host Marriott, then, to the extent of the asset's "built-in gain," such gain will be subject to tax at the highest regular corporate rate applicable. Built-in gain is the excess of the fair market value of an asset over Host Marriott's adjusted basis in the asset, determined when Host Marriott acquired the asset. Host Marriott owns an indirect interest in appreciated assets that its predecessors held before the REIT conversion. Such appreciated assets have a "carryover" basis and thus have built-in gain with respect to Host Marriott. If such appreciated property is sold within the ten-year period following the REIT conversion, or prior to January 1, 2009, Host Marriott generally will be subject to regular corporate tax on that gain to the extent of the built-in gain in that property at the time of the REIT conversion. The total amount of gain on which Host Marriott can be taxed is limited to the excess of the aggregate fair market value of its assets on January 1, 1999 over the adjusted tax bases of those assets at that time. This tax could be very material. As a result, the operating partnership and Host Marriott may seek to avoid a taxable disposition prior to January 1, 2009 of any significant asset owned by Host Marriott's predecessors at the time of the REIT conversion. This could be true with respect to a particular disposition even though the disposition might otherwise be in the best interests of Host Marriott and its shareholders. Notwithstanding Host Marriott's status as a REIT, it is likely that substantial deferred liabilities of its predecessors will be recognized prior to January 1, 2009. Deferred liabilities include, but are not limited to, tax liabilities attributable to built-in gain assets and deferred tax liabilities attributable to taxable income for which neither Host Marriott nor the operating partnership will receive corresponding cash. In addition, the IRS could assert substantial additional liabilities for taxes against Host Marriott's predecessors for taxable years prior to the time Host Marriott qualified as a REIT. Under the terms of the REIT conversion and the partnership agreement of the operating partnership, the operating partnership will be responsible for paying, or reimbursing Host Marriott for the payment of, any federal corporate income tax imposed on built-in gain as well as any other liabilities, including contingent liabilities and liabilities attributable to litigation that Host Marriott may incur, whether such liabilities are incurred by reason of activities prior to the REIT conversion or activities subsequent thereto. Accordingly, the operating partnership will pay, or reimburse Host Marriott for the payment of, all taxes incurred by Host Marriott, except for taxes imposed on Host Marriott by reason of its failure to qualify as a REIT or to distribute to its shareholders an amount equal to its "REIT taxable income," including net capital gains. Requirements for qualification. The Internal Revenue Code defines a REIT as a corporation, trust or association (1) which is managed by one or more directors or trustees; S-58

(2) the beneficial ownership of which is evidenced by transferable shares or by transferable certificates of beneficial interest; (3) which would be taxable as a domestic corporation, but for Sections 856 through 859 of the Internal Revenue Code; (4) which is neither a financial institution nor an insurance company subject to certain provisions of the Internal Revenue Code; (5) the beneficial ownership of which is held by 100 or more persons; (6) during the last half of each taxable year, not more than 50% in value of the outstanding stock of which is owned, actually or constructively, by five or fewer individuals (as defined in the Internal Revenue Code to include certain entities); (7) which makes an election to be taxable as a REIT, or has made this election for a previous taxable year which has not been revoked or terminated, and satisfies all relevant filing and other administrative requirements established by the Internal Revenue Service that must be met to elect and maintain REIT status; (8) which uses a calendar year for federal income tax purposes and complies with the recordkeeping requirements of the Internal Revenue Code and regulations promulgated thereunder; and (9) which meets certain other tests, described below, regarding the nature of its income and assets. Conditions (1) to (4) must be met during the entire taxable year and condition (5) must be met during at least 335 days of a taxable year of twelve months, or during a proportionate part of a taxable year of less than twelve months. Conditions (5) and (6) did not apply to Host Marriott's 1999 taxable year. Compliance with condition (5) is determined by disregarding the ownership of shares of stock of Host Marriott by any person(s) who: (a) acquired such shares of stock as a gift or bequest or pursuant to a legal separation or divorce; (b) is the estate of any person making such transfer to the estate; or (c) is a company established exclusively for the benefit of, or wholly owned by, either the person making such transfer or a person described in (a) or (b). For purposes of determining stock ownership under condition (6) above, a supplemental unemployment compensation benefits plan, a private foundation or a portion of a trust permanently set aside or used exclusively for charitable purposes generally is considered an individual. However, a trust that is a qualified trust under Internal Revenue Code Section 401(a) generally is not considered an individual, and beneficiaries of a qualified trust are treated as holding shares of a REIT in proportion to their actuarial interests in the trust for purposes of condition (6) above. In connection with condition (6), Host Marriott is required to send annual letters to its shareholders requesting information regarding the actual ownership of its shares of stock. If Host Marriott complies with this requirement, and it does not know, or exercising reasonable diligence would not have known, whether it failed to meet condition (6), then it will be treated as having met condition (6). If Host Marriott fails to send such annual letters, it will be required to pay either a $25,000 penalty or, if the failure is intentional, a $50,000 penalty. The IRS may require Host Marriott, under those circumstances, to take further action to ascertain actual ownership of its shares of stock, and failure to comply with such an additional requirement would result in an additional $25,000 (or $50,000) penalty. No penalty would be assessed in the first instance, however, if the failure to send the letters is due to reasonable cause and not to willful neglect. Host Marriott believes that it meets and will continue to meet conditions (1) through (4). In addition, Host Marriott believes that it has had and continues to have outstanding common stock with sufficient diversity of S-59

ownership to allow it to satisfy conditions (5) and (6). With respect to condition (6), Host Marriott has complied and intends to continue to comply with the requirement that it send annual letters to its shareholders requesting information regarding the actual ownership of its shares of stock. In addition, Host Marriott's charter contains an ownership limit that is intended to assist Host Marriott in continuing to satisfy the share ownership requirements described in (5) and (6) above. The ownership limit, together with compliance with the annual shareholder letter requirement described above, however, may not ensure that Host Marriott will, in all cases, be able to satisfy the share ownership requirements described above. If Host Marriott fails to satisfy such share ownership requirements, Host Marriott will not qualify as a REIT. See "-- Failure of Host Marriott to qualify as a REIT" below. A corporation may not elect to become a REIT unless its taxable year is the calendar year. Although Host Marriott previously had a 52-53 week year ending on the Friday closest to January 1, it adopted a calendar year taxable year in connection with the REIT conversion. Distribution of "earnings and profits" attributable to "C" corporation taxable years. A REIT cannot have at the end of any taxable year any undistributed earnings and profits ("E&P") that are attributable to a "C" corporation taxable year, which includes all undistributed E&P of Host Marriott's predecessors. Accordingly, Host Marriott had until December 31, 1999 to distribute such E&P. In connection with the REIT conversion, Host Marriott declared dividends intended to eliminate the substantial majority, if not all, of such E&P. To the extent, however, that any such E&P remained (the "Acquired Earnings") and Host Marriott failed to distribute such Acquired Earnings prior to the end of 1999, Host Marriott would be disqualified as a REIT at least for 1999. If Host Marriott should be so disqualified for 1999, subject to the satisfaction by Host Marriott of certain "deficiency dividend" procedures described below in "--Annual distribution requirements applicable to REITs" and assuming that Host Marriott otherwise satisfies the requirements for qualification as a REIT, Host Marriott should qualify as a REIT for 2000 and thereafter. Host Marriott believes that the dividends it paid prior to December 31, 1999 were sufficient to distribute all of the Acquired Earnings as of December 31, 1999. However, there are substantial uncertainties relating to both the estimate of the Acquired Earnings, as described below, and the value of noncash consideration that Host Marriott distributed. Accordingly, there can be no assurance this requirement was met. The estimated amount of the Acquired Earnings is based on the allocated consolidated E&P of Host Marriott's predecessors accumulated from 1929 through and including 1998 and takes into account the allocation, as a matter of law, of 81% of Host Marriott's predecessors' accumulated E&P to Marriott International on October 8, 1993 in connection with the spin-off of Marriott International. The estimate was determined based on the available tax returns and certain assumptions with respect to both such returns and other matters. The calculation of the Acquired Earnings, however, depends upon a number of factual and legal interpretations related to the activities and operations of Host Marriott's predecessors during their entire corporate existence and is subject to review and challenge by the IRS. There can be no assurance that the IRS will not examine the tax returns of Host Marriott's predecessors and propose adjustments to increase their taxable income. The impact of such proposed adjustments, if any, may be material. If the IRS examines Host Marriott's calculation of its E&P, the IRS can consider all taxable years of Host Marriott's predecessors as open for review for purposes of such determination. Hogan & Hartson L.L.P. has expressed no opinion as to the amount of E&P of Host Marriott and Host Marriott's predecessors. Accordingly, for purposes of its opinion as to the qualification of Host Marriott as a REIT, Hogan & Hartson L.L.P. relied upon a representation from Host Marriott that as of the end of 1999 it had eliminated all Acquired Earnings. Qualified REIT subsidiary. If a REIT owns a corporate subsidiary that is a "qualified REIT subsidiary," that subsidiary will be disregarded for federal income tax purposes, and all assets, liabilities and items of income, deduction and credit of the subsidiary will be treated as assets, liabilities and items of the REIT itself. Generally, a qualified REIT subsidiary is a corporation all of the capital stock of which is owned by one REIT and that is not a taxable REIT subsidiary. Host Marriott holds several qualified REIT subsidiaries S-60

that hold de minimis indirect interests in the partnerships that own hotels. These entities are not subject to federal corporate income taxation, although they may be subject to state and local taxation in certain jurisdictions. Ownership of partnership interests by a REIT. A REIT which is a partner in a partnership will be deemed to own its proportionate share of the assets of the partnership and will be deemed to be entitled to the income of the partnership attributable to such share. In addition, the character of the assets and gross income of the partnership retains the same character in the hands of the REIT for purposes of the gross income tests and the asset tests applicable to REITs, as described below. Thus, Host Marriott's proportionate share of the assets and items of income of the operating partnership, including the operating partnership's share of such items of any subsidiaries that are partnerships or LLCs, are treated as assets and items of income of Host Marriott for purposes of applying the requirements described herein. A summary of the rules governing the federal income taxation of partnerships and their partners is provided below in "--Tax aspects of Host Marriott's ownership of interests in the operating partnership." As the sole general partner of the operating partnership, Host Marriott has direct control over the operating partnership and indirect control over the subsidiaries in which the operating partnership or a subsidiary has a controlling interest. Host Marriott intends to operate these entities consistent with the requirements for qualification of Host Marriott as a REIT. Income tests applicable to REITs. In order to maintain qualification as a REIT, Host Marriott must satisfy the following two gross income requirements: . At least 75% of Host Marriott's gross income, excluding gross income from "prohibited transactions," for each taxable year must be derived directly or indirectly from investments relating to real property or mortgages on real property, including "rents from real property," gains on the disposition of real estate, dividends paid by another REIT and interest on obligations secured by mortgages on real property or on interests in real property, or from some types of temporary investments. . At least 95% of Host Marriott's gross income, excluding gross income from "prohibited transactions," for each taxable year must be derived from any combination of income qualifying under the 75% test, dividends, interest, some payments under hedging instruments and gain from the sale or disposition of stock or securities, including some hedging instruments. Rents paid pursuant to Host Marriott's leases, together with gain on the disposition of assets and dividends and interest received from the non- controlled subsidiaries and HMT Lessee will constitute substantially all of the gross income of Host Marriott. Several conditions must be satisfied in order for rents received by Host Marriott, including the rents received pursuant to the leases, to qualify as "rents from real property." First, the amount of rent must not be based in whole or in part on the income or profits of any person. However, an amount received or accrued generally will not be excluded from the term "rents from real property" solely by reason of being based on a fixed percentage or percentages of receipts or sales. Second, rents received from a tenant will not qualify as "rents from real property" if Host Marriott, or an actual or constructive owner of 10% or more of Host Marriott, actually or constructively owns 10% or more of the tenant. This type of tenant will be referred to below as a related party tenant. As a result of the passage of the REIT Modernization Act, however, for taxable years beginning after December 31, 2000, Host Marriott is able to lease its hotel properties to a taxable REIT subsidiary, HMT Lessee, and the rents received from that subsidiary will not be disqualified from being "rents from real property" by reason of Host Marriott's ownership interest in the subsidiary so long as the property is a "qualified lodging facility" and is operated on behalf of the taxable REIT subsidiary by an "eligible independent contractor." A taxable REIT subsidiary, which is subject to federal income tax, is an entity taxable as a corporation other than a REIT in which a REIT directly or indirectly holds stock or other equity interests, that has made a joint election with the REIT to be treated as a taxable REIT subsidiary and that does not engage in certain activities, including, without limitation, operating or managing hotels, except through an "eligible independent contractor." For a more detailed discussion of taxable REIT subsidiaries, see "--Qualification of an entity as a taxable REIT subsidiary," S-61

below. HMT Lessee and each of the non-controlled subsidiaries will elect and, Host Marriott believes, will qualify to be treated as a taxable REIT subsidiary for federal income tax purposes, effective January 1, 2001. Third, if rent attributable to personal property leased in connection with a lease of real property is greater than 15% of the total rent received under the lease, then the portion of rent attributable to such personal property will not qualify as "rents from real property." Under prior law, this 15% test was based on relative adjusted tax bases. For taxable years beginning after December 31, 2000, however, the test is based on relative fair market values. Fourth, if Host Marriott operates or manages a property or furnishes or renders certain "impermissible services" to the tenants at the property, and the income derived from the services exceeds one percent of the total amount received by Host Marriott with respect to the property, then no amount received by Host Marriott with respect to the property will qualify as "rents from real property." Impermissible services are services other than services (1) "usually or customarily rendered" in connection with the rental of real property and (2) not otherwise considered "rendered to the occupant." For these purposes, the income that Host Marriott is considered to receive from the provision of "impermissible services" will not be less than 150% of the cost of providing the service. If the amount so received is one percent or less of the total amount received by the REIT with respect to the property, then only the income from the impermissible services will not qualify as "rents from real property." There are two exceptions to this rule. First, impermissible services can be provided to tenants through an independent contractor from whom Host Marriott derives no income. To the extent that impermissible services are provided by an independent contractor, the cost of the services must be borne by the independent contractor. Second, for Host Marriott's taxable years beginning after December 31, 2000, impermissible services can be provided to tenants at a property by a taxable REIT subsidiary. The operating partnership and each subsidiary that owns hotels entered into leases with subsidiaries of Crestline that commenced on January 1, 1999 and pursuant to which the hotels are leased for an initial term ranging generally from seven to ten years. Each lease provides for thirteen payments per annum of a specified base rent plus, to the extent that it exceeds the base rent, additional rent which is calculated based upon the gross sales of the hotels subject to the lease, plus certain other amounts. Effective November 15, 1999, we amended substantially all of our leases with Crestline to give Crestline the right to renew each of these leases for up to four additional terms of seven years each at a fair rental value, to be determined either by agreement between us and Crestline or through arbitration at the time the renewal option is exercised. These amendments provided that Crestline was under no obligation to exercise these renewal options, and we had the right to terminate the renewal options during certain time periods specified in the amendments. As a result of the REIT Modernization Act, beginning January 1, 2001, we are permitted to lease our hotel properties to a taxable REIT subsidiary so long as each hotel property is a "qualified lodging facility" and is operated by an "eligible independent contractor." Our leases with Crestline provided that, following the enactment of the REIT Modernization Act, we had the right, beginning on January 1, 2001, to purchase, or have our taxable REIT subsidiary purchase, the leases for a purchase price equal to the fair market value of Crestline's interests in the leases, excluding any renewal period provided for in the leases. On November 13, 2000, HMT Lessee, which will elect to be taxed as a taxable REIT subsidiary effective as of January 1, 2001, agreed to purchase from Crestline the entities owning the leasehold interests in 112 of our hotels (and the leasehold interests in an additional four hotels) for approximately $207 million. We consummated this acquisition, effective as of January 1, 2001. We believe that, as of January 1, 2001, each of our hotel properties is a "qualified lodging facility" and that each manager of our hotel properties qualifies as an "eligible independent contractor." Neither Host Marriott nor the operating partnership has done or intends to do any of the following: . provide any services to the lessees with respect to the operation of the hotels, including lessees that are taxable REIT subsidiaries of Host Marriott, that would be considered "impermissible services" if the S-62

resulting income considered attributable to such services would cause Host Marriott to fail to satisfy the 95% gross income test described above; . charge rent to the lessee of any hotel, including a lessee that is a taxable REIT subsidiary of Host Marriott, that is based in whole or in part on the income or profits of any person, other than by reason of being based on a fixed percentage or percentages of receipts or sales (except for the lease of the Harbor Beach Resort, where the lease provides for rent based upon net profits but which rent Host Marriott currently believes will not jeopardize Host Marriott's status as a REIT); . rent any hotel to a related party tenant (except for leases to a taxable REIT subsidiary, including HMT Lessee, after December 31, 2000 of hotel properties that are "qualified lodging facilities" that are operated and managed by "eligible independent contractors"), unless the rent received from the related party tenant and will not jeopardize Host Marriott's status as a REIT; or . derive rental income attributable to personal property other than personal property leased in connection with the lease of real property, the amount of which is less than 15% of the total rent received under the lease, unless the amount of such rent attributable to personal property will not jeopardize Host Marriott's status as a REIT. As discussed above, in order for the rent paid pursuant to the leases to constitute "rents from real property," the leases must be respected as true leases for federal income tax purposes. Accordingly the leases cannot be treated as service contracts, joint ventures or some other type of arrangement. The determination of whether the leases are true leases depends upon an analysis of all the surrounding facts and circumstances. In making such a determination, courts have considered a variety of factors, including the following: . the intent of the parties; . the form of the agreement; . the degree of control over the property that is retained by the property owner (e.g., whether the lessee has substantial control over the operation of the property or whether the lessee was required simply to use its best efforts to perform its obligations under the agreement); and . the extent to which the property owner retains the risk of loss with respect to the property (e.g., whether the lessee bears the risk of increases in operating expenses or the risk of damage to the property) or the potential for economic gain (e.g., appreciation) with respect to the property. In addition, Section 7701(e) of the Internal Revenue Code provides that a contract that purports to be a service contract or a partnership agreement is treated instead as a lease of property if the contract is properly treated as such, taking into account all relevant factors. Since the determination of whether a service contract should be treated as a lease is inherently factual, the presence or absence of any single factor may not be dispositive in every case. Some of the relevant factors include whether: . the service recipient is in physical possession of the property; . the service recipient controls the property; . the service recipient has a significant economic or possessory interest in the property (e.g., the property's use is likely to be dedicated to the service recipient for a substantial portion of the useful life of the property, the recipient shares the risk that the property will decline in value, the recipient shares in any appreciation in the value of the property, the recipient shares in savings in the property's operating costs or the recipient bears the risk of damage to or loss of the property); . the service provider does not bear any risk of substantially diminished receipts or substantially increased expenditures if there is nonperformance under the contract; . the service provider does not use the property concurrently to provide significant services to entities unrelated to the service recipient; and S-63

. the total contract price does not substantially exceed the rental value of the property for the contract period. Host Marriott's leases have been structured with the intent to qualify as true leases for federal income tax purposes. For example, with respect to each lease: . the operating partnership or the applicable subsidiary or other lessor entity and the lessee intend for their relationship to be that of a lessor and lessee and such relationship is documented by a lease agreement; . the lessee has the right to exclusive possession and use and quiet enjoyment of the hotels covered by the lease during the term of the lease; . the lessee bears the cost of, and will be responsible for, day-to-day maintenance and repair of the hotels other than the cost of certain capital expenditures, and will dictate through the hotel managers, who work for the lessees during the terms of the leases, how the hotels are operated and maintained; . the lessee bears all of the costs and expenses of operating the hotels, including the cost of any inventory used in their operation, during the term of the lease, other than the cost of certain furniture, fixtures and equipment, and certain capital expenditures; . the lessee benefits from any savings and bears the burdens of any increases in the costs of operating the hotels during the term of the lease; . in the event of damage or destruction to a hotel, the lessee is at economic risk because it will bear the economic burden of the loss in income from operation of the hotels subject to the right, in certain circumstances, to terminate the lease if the lessor does not restore the hotel to its prior condition; . the lessee has indemnified the operating partnership or the applicable subsidiary against all liabilities imposed on the operating partnership or the applicable subsidiary during the term of the lease by reason of (A) injury to persons or damage to property occurring at the hotels or (B) the lessee's use, management, maintenance or repair of the hotels; . the lessee is obligated to pay, at a minimum, substantial base rent for the period of use of the hotels under the lease; . the lessee stands to incur substantial losses or reap substantial gains depending on how successfully it, through the hotel managers, who work for the lessees during the terms of the leases, operates the hotels; . Host Marriott and the operating partnership believe that each lessee reasonably expected at the time the leases were entered into to derive a meaningful profit, after expenses and taking into account the risks associated with the lease, from the operation of the hotels during the term of its leases; and . upon termination of each lease, the applicable hotel is expected to have a remaining useful life equal to at least 20% of its expected useful life on the date of the consummation of the REIT conversion, and a fair market value equal to at least 20% of its fair market value on the date of the consummation of the REIT conversion. If, however, the leases were recharacterized as service contracts or partnership agreements, rather than true leases, or disregarded altogether for tax purposes, all or part of the payments that the operating partnership receives from the lessees would not be considered rent or would not otherwise satisfy the various requirements for qualification as "rents from real property." In that case, Host Marriott very likely would not be able to satisfy either the 75% or 95% gross income tests and, as a result, would lose its REIT status. In addition, except for permitted leases to a taxable REIT subsidiary of "qualified lodging facilities" operated by "eligible independent contractors," the lessees must not be regarded as related party tenants. A lessee of Host Marriott (including for years ending prior to January 1, 2001, all of the Crestline lessees and, for the years beginning on or after January 1, 2001, the Crestline lessees owning the hotel leasehold interests not acquired from Crestline by HMT Lessee) will be regarded as a related party tenant only if Host Marriott and/or one or more actual or constructive owners of 10% or more of Host Marriott actually or constructively own 10% S-64

or more of such lessee (including, with regard to a Crestline lessee, through an ownership interest in Crestline). In order to help preclude our lessees from being regarded as related party tenants, the following organizational documents contain the following ownership limits: . the articles of incorporation of Crestline expressly prohibit any person or persons acting as a group, including Host Marriott and/or any 10% or greater shareholder of Host Marriott, from owning more than 9.8% of the lesser of the number or value of the shares of capital stock of Crestline; . Host Marriott's charter expressly prohibits any person or persons acting as a group or entity from owning, actually and/or constructively, more than 9.8% of the lesser of the number or value of the shares of capital stock of Host Marriott (subject to a limited exception for a holder of shares of capital stock of Host Marriott in excess of the ownership limit solely by reason of the merger of Host Marriott's predecessor into Host Marriott, which exception applied, to the extent that the holder thereof did not own, directly or by attribution under the Internal Revenue Code, more than 9.9% in value of the outstanding shares of capital stock of Host Marriott as a result of the merger) or any other class or series of shares of stock of Host Marriott; and . the operating partnership's partnership agreement expressly prohibits any person, or persons acting as a group, or entity, other than Host Marriott and an affiliate of The Blackstone Group and a series of related funds controlled by Blackstone Real Estate Partners (the "Blackstone Entities"), from owning more than 4.9% by value of any class of interests in the operating partnership. Each of these prohibitions contains self-executing enforcement mechanisms. Assuming that these prohibitions are enforced at all times and no waivers thereto are granted, the lessees should not be regarded as related party tenants. There can be no assurance, however, that these ownership restrictions will be enforced in accordance with their terms in all circumstances or otherwise will ensure that the lessees will not be regarded as related party tenants. As indicated above, "rents from real property" must not be based in whole or in part on the income or profits of any person. Payments made pursuant to Host Marriott's leases should qualify as "rents from real property" since they are based on either fixed dollar amounts or on specified percentages of gross sales fixed at the time the leases were entered into, except for the lease of the Harbor Beach Resort, which lease provides for rents based upon net profits. The foregoing assumes that the leases are not renegotiated during their term in a manner that has the effect of basing either the percentage rent or base rent on income or profits. The foregoing also assumes that the leases are not in reality used as a means of basing rent on income or profits. More generally, the rent payable under the leases will not qualify as "rents from real property" if, considering the leases and all the surrounding circumstances, the arrangement does not conform with normal business practice. Host Marriott intends that it will not renegotiate the percentages used to determine the percentage rent during the terms of the leases in a manner that has the effect of basing rent on income or profits. In addition, Host Marriott believes that the rental provisions and other terms of the leases conform with normal business practice and, other than the Harbor Beach Resort lease, were not intended to be used as a means of basing rent on income or profits. Furthermore, Host Marriott intends that, with respect to other properties that it acquires in the future, it will not charge rent for any property that is based in whole or in part on the income or profits of any person, except by reason of being based on a fixed percentage of gross revenues, as described above. Host Marriott leases certain items of personal property to the lessees in connection with its leases. Under the Internal Revenue Code, if a lease provides for the rental of both real and personal property and the portion of the rent attributable to personal property is 15% or less of the total rent due under the lease, then all rent paid pursuant to such lease qualifies as "rent from real property." If, however, a lease provides for the rental of both real and personal property, and the portion of the rent attributable to personal property exceeds 15% of the total rent due under the lease, then no portion of the rent that is attributable to personal property will qualify as "rent from real property." Under the law in effect prior to January 1, 2001, the amount of rent attributable to personal property is that amount which bears the same ratio to total rent for the taxable year as the average of the adjusted tax bases of the personal property at the beginning and end of the year bears to the S-65

average of the aggregate adjusted tax bases of both the real and personal property at the beginning and end of such year. Host Marriott has represented that, with respect to each of its leases that includes a lease of items of personal property, the amount of rent attributable to personal property with respect to such lease will not exceed 15% of the total rent due under the lease (determined under the law in effect for the applicable period), except for a relatively small group of leases where the rent attributable to personal property, which would constitute non-qualifying income for purposes of the 75% and 95% gross income tests, would not be material relative to the overall gross income of Host Marriott. For Host Marriott's taxable years beginning after December 31, 2000, the personal property test is based on fair market value as opposed to adjusted tax basis. Each lease permits the operating partnership to take certain measures, including requiring the lessee to purchase certain furniture, fixtures and equipment or to lease such property from a third party, including a non- controlled subsidiary, if necessary to ensure that all of the rent attributable to personal property with respect to such lease will qualify as "rent from real property." In order to protect Host Marriott's ability to qualify as a REIT, the operating partnership sold substantial personal property associated with a number of hotels acquired in connection with the REIT conversion to a non- controlled subsidiary. The non-controlled subsidiary separately leases all such personal property directly to the applicable lessee and receives rental payments that Host Marriott believes represent the fair rental value of such personal property directly from the lessees. If such arrangements are not respected for federal income tax purposes, Host Marriott likely would not qualify as a REIT. If any of the hotels were to be operated directly by the operating partnership or a subsidiary as a result of a default by a lessee under the applicable lease, such hotel would constitute foreclosure property until the close of the third tax year following the tax year in which it was acquired, or for up to an additional three years if an extension is granted by the IRS, provided that: (1) the operating entity conducts operations through an independent contractor, which might, but would not necessarily in all circumstances, include Marriott International and its subsidiaries, within 90 days after the date the hotel is acquired as the result of a default by a lessee; (2) the operating entity does not undertake any construction on the foreclosed property other than completion of improvements that were more than 10% complete before default became imminent; (3) foreclosure was not regarded as foreseeable at the time the applicable lessor entered into such lease; and (4) Host Marriott elects on its federal income tax return filed for the year in which the foreclosure occurred to treat the hotel as "foreclosure property." For as long as such hotel constitutes foreclosure property, the income from the hotel would be subject to tax at the maximum corporate rates, but it would qualify under the 75% and 95% gross income tests. However, if such hotel does not constitute foreclosure property at any time in the future, income earned from the disposition or operation of such hotel will not qualify under the 75% and 95% gross income tests. For Host Marriott's taxable years beginning after December 31, 2000, if a lessee defaults under a lease, the operating partnership would be permitted to lease the hotel to a taxable REIT subsidiary, subject to the limitations described above, and the hotel would not become foreclosure property. "Interest" generally will be nonqualifying income for purposes of the 75% or 95% gross income tests if it depends in whole or in part on the income or profits of any person. However, interest will not fail so to qualify solely by reason of being based upon a fixed percentage or percentages of receipts or sales. Host Marriott has received and will continue to receive interest payments from the non-controlled subsidiaries and, with regard to its taxable years beginning on or after January 1, 2001, expects to receive interest payments from HMT Lessee. These amounts of interest will be qualifying income for purposes of the 95% gross income test but not the 75% gross income test. Host Marriott does not anticipate that the amounts of interest derived from the non-controlled subsidiaries and HMT Lessee will be sufficiently substantial to affect its ability to continue to satisfy the 75% gross income test. S-66

The non-controlled subsidiaries and HMT Lessee hold various assets, the ownership of which by the operating partnership might jeopardize Host Marriott's status as a REIT. The assets owned by the non-controlled subsidiaries primarily consist of partnership or other interests in hotels that are not leased, certain foreign hotels, and the personal property associated with certain hotels. The assets owned by HMT Lessee primarily consist of the equity interests in the entities owning the leasehold interests in substantially all of Host Marriott's full-service hotel properties. Each non- controlled subsidiary is, and HMT Lessee will start effective January 1, 2001, to be, taxable as a regular "C" corporation. The operating partnership's share of any dividends received from a non-controlled subsidiary or HMT Lessee should qualify for purposes of the 95% gross income test but not for purposes of the 75% gross income test. The operating partnership does not anticipate that it will receive sufficient dividends from the non-controlled subsidiaries and HMT Lessee to cause it to fail the 75% gross income test. Each non-controlled subsidiary and HMT Lessee intends to elect, with Host Marriott, to be treated as a taxable REIT subsidiary effective January 1, 2001. Host Marriott inevitably will have some gross income from various sources that fails to constitute qualifying income for purposes of one or both of the 75% or 95% gross income tests. These include, but are not limited to, the following: . "safe harbor" leases; . the lease of the Harbor Beach Resort, which provides for rent based upon net profits; . the operation of the hotel that is located in Sacramento; . minority partnership interests in partnerships that own hotels that are not leased under leases that produce rents qualifying as "rents from real property"; . rent attributable to personal property at a relatively small group of hotels that does not satisfy the 15% personal property test; and . interest and dividends paid by the non-controlled subsidiaries and HMT Lessee, which amounts will qualify for purposes of the 95% gross income test but not for purposes of the 75% gross income test. Host Marriott believes that, taking into account the anticipated sources of non-qualifying income, its aggregate gross income from all sources will satisfy the 75% and 95% gross income tests applicable to REITs for each taxable year commencing subsequent to the date of the REIT conversion. If Host Marriott fails to satisfy one or both of the 75% or 95% gross income tests for any taxable year, it may nevertheless qualify as a REIT for such year if it is entitled to relief under certain provisions of the Internal Revenue Code. These relief provisions will be generally available if Host Marriott's failure to meet such tests was due to reasonable cause and not due to willful neglect, Host Marriott attaches a schedule of the sources of its income to its federal income tax return, and any incorrect information set forth on the schedule was not due to fraud with intent to evade tax. It is not possible, however, to state whether in all circumstances Host Marriott would be entitled to the benefit of these relief provisions. For example, if Host Marriott fails to satisfy the gross income tests because nonqualifying income that Host Marriott intentionally incurs exceeds the limits on such income, the IRS could conclude that Host Marriott's failure to satisfy the tests was not due to reasonable cause. If these relief provisions are inapplicable to a particular set of circumstances involving Host Marriott, Host Marriott will not qualify as a REIT. As discussed above under "--General" even if these relief provisions apply, a tax would be imposed with respect to the excess net income. Any gain realized by Host Marriott on the sale of any property held as inventory or other property held primarily for sale to customers in the ordinary course of business, including Host Marriott's share of any such gain realized by the operating partnership, will be treated as income from a "prohibited transaction" that is subject to a 100% penalty tax. Under existing law, whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business is a question of fact that depends upon all the facts and circumstances with respect to the particular transaction. The operating partnership intends that both it and its subsidiaries will hold hotels for investment with a view to long-term appreciation, to engage in the business of acquiring and owning hotels and to make occasional sales of hotels as are consistent with the operating S-67

partnership's investment objectives. There can be no assurance, however, that the IRS might not contend that one or more of these sales is subject to the 100% penalty tax, particularly if the hotels that are sold have been held for a relatively short period of time. Asset tests applicable to REITs. At the close of each quarter of its taxable year, Host Marriott must satisfy the following four tests relating to the nature of its assets: . First, at least 75% of the value of Host Marriott's total assets must be represented by real estate assets. Host Marriott's real estate assets include, for this purpose, its allocable share of real estate assets held by the operating partnership and the non-corporate subsidiaries of the operating partnership, as well as stock or debt instruments held for less than one year purchased with the proceeds of a stock offering or a long- term (at least five years) debt offering of Host Marriott, cash, cash items and government securities. Host Marriott's real estate assets do not include stock or debt instruments issued by its non-controlled subsidiaries or HMT Lessee (other than mortgages). . Second, no more than 25% of Host Marriott's total assets may be represented by securities other than those in the 75% asset class. . Third, of the investments included in the 25% asset class, the value of any one issuer's securities owned by Host Marriott may not exceed 5% of the value of Host Marriott's total assets and Host Marriott may not own more than 10% of either the outstanding voting securities or the value of the outstanding securities of any one issuer. For 2001 and later years, this limit does not apply to securities of a taxable REIT subsidiary. For years prior to 2001, the 10% limit applies only with respect to voting securities of any issuer and not to the value of the securities of any issuer. . Fourth, for taxable years beginning after December 31, 2000, not more than 20% of the value of Host Marriott's total assets may be represented by securities of taxable REIT subsidiaries. HMT Lessee and each of the non-controlled subsidiaries will elect to be a taxable REIT subsidiary, effective as of January 1, 2001. For years prior to 2001, the operating partnership did not own any of the voting stock of the non-controlled subsidiaries but it did own 100% of the nonvoting stock of each non-controlled subsidiary. Neither Host Marriott, the operating partnership, nor any of the non-corporate subsidiaries of the operating partnership has owned or will own more than 10% of the voting securities of any entity that is treated as a corporation for federal income tax purposes, except for, with regard to periods beginning after December 31, 2000, corporations or other entities that qualify and elect to be treated as taxable REIT subsidiaries. In addition, Host Marriott believes that the value of the securities of any one issuer owned by Host Marriott, the operating partnership, or any of the non-corporate subsidiaries of the operating partnership, including Host Marriott's pro rata share of the value of the securities of each non-controlled subsidiary, has not exceeded 5% of the total value of Host Marriott's assets for years prior to January 1, 2001 and will not exceed that percentage threshold in subsequent years unless the issuer is a taxable REIT subsidiary. There can be no assurance, however, that the IRS might not contend that the value of such securities exceeds one or more of the value limitations or that nonvoting stock of a non-controlled subsidiary or another corporate entity owned by the operating partnership should be considered "voting stock" for this purpose. After initially meeting the asset tests at the close of any quarter, Host Marriott will not lose its status as a REIT for failure to satisfy the asset tests at the end of a later quarter solely by reason of changes in asset values. If the failure to satisfy the asset tests results from an acquisition of securities or other property during a quarter, the failure can be cured by disposition of sufficient nonqualifying assets within 30 days after the close of that quarter. An example of such an acquisition would be an increase in Host Marriott's interest in the operating partnership as a result of the exercise of a limited partner's unit redemption right or an additional capital contribution of proceeds from an offering of capital stock by Host Marriott. Host Marriott maintains adequate records of the value of its assets to ensure compliance with the asset tests and intends to take such other actions within 30 days after the close of any quarter as may be required to cure any noncompliance. If S-68

Host Marriott fails to cure noncompliance with the asset tests within such time period, Host Marriott would cease to qualify as a REIT. Qualification of an entity as a taxable REIT subsidiary. To qualify as a "taxable REIT subsidiary," an entity must be taxable as a corporation and must satisfy the following additional requirements: . a REIT must own an interest in the entity, whether directly or indirectly; . the entity must elect, together with the REIT that owns its stock, to be treated as a taxable REIT subsidiary under the Code; and . the entity must not directly or indirectly operate or manage a lodging facility or a health care facility or, generally, provide to another person, under a franchise, license or otherwise, rights to any brand name under which any lodging facility or health care facility is operated. Although a taxable REIT subsidiary may not operate or manage a lodging facility, it may lease such a facility so long as the facility is a "qualified lodging facility" and is operated on behalf of the taxable REIT subsidiary by an "eligible independent contractor." A "qualified lodging facility" is, generally, a hotel or motel at which no authorized gambling activities are conducted, and the customary amenities and facilities operated as part of, or associated with, the hotel or motel. An "eligible independent contractor" is an independent contractor that, at the time a management agreement is entered into with a taxable REIT subsidiary to operate a "qualified lodging facility," is actively engaged in the trade or business of operating "qualified lodging facilities" for a person or persons unrelated to either the taxable REIT subsidiary or any REITs with which the taxable REIT subsidiary is affiliated. A hotel management company that otherwise would qualify as an "eligible independent contractor" with regard to a taxable REIT subsidiary of Host Marriott will not so qualify if the hotel management company and/or one or more actual or constructive owners of 10% or more of the hotel management company actually or constructively own more than 35% of Host Marriott, or one or more actual or constructive owners of more than 35% of the hotel management company own 35% or more of Host Marriott (determined taking into account only the stock held by persons owning, directly or indirectly, more than 5% of the outstanding common stock of Host Marriott and, if the stock of the eligible independent contractor is publicly-traded, 5% of the publicly-traded stock of the eligible independent contractor). Host Marriott believes, and will take all steps reasonably practicable to ensure, that neither HMT Lessee nor any of the non- controlled subsidiaries will be considered engaged in "operating" or "managing" its hotels and that the hotel management companies engaged to operate and manage its hotels, including Marriott International and Crestline Hotels and Resorts, Inc., qualify as "eligible independent contractors" with regard to HMT Lessee and the non-controlled subsidiaries. Certain restrictions imposed on taxable REIT subsidiaries are intended to ensure that such entities will be subject to an appropriate level of federal income taxation. First, a taxable REIT subsidiary may not deduct interest payments made in any year to an affiliated REIT to the extent that such payments exceed, generally, 50% of the taxable REIT subsidiary's adjusted taxable income for that year (although the taxable REIT subsidiary may carry forward to, and deduct in, a succeeding year the disallowed interest amount if the 50% test is satisfied). In addition, if a taxable REIT subsidiary pays interest, rent or another amount to a REIT that exceeds the amount that would be paid to an unrelated party in an arm's length transaction, the REIT generally will be subject to an excise tax equal to 100% of such excess. HMT Lessee and the non-controlled subsidiaries (which will elect to be taxed as taxable REIT subsidiaries, effective January 1, 2001) will make substantial interest and other payments to Host Marriott, including payments of rent under the hotel leases that have been acquired from Crestline by HMT Lessee. There can be no assurance that the limitation on interest deductions applicable to taxable REIT subsidiaries will not apply to the interest payments made to Host Marriott by HMT Lessee or the non-controlled subsidiaries after January 1, 2001, resulting in an increase in the corporate tax liability of each such subsidiary. Moreover, there can be no assurance that the terms establishing the payments made by the taxable REIT subsidiary or the non-controlled subsidiaries to Host Marriott will not result in the imposition of the 100% excise tax to a portion of any such payment. S-69

Annual distribution requirements applicable to REITs. Host Marriott, in order to qualify as a REIT, is required to distribute dividends, other than capital gain dividends, to its shareholders in an amount at least equal to (i) the sum of (a) 90% (95% for taxable years ending before January 1, 2001) of "REIT taxable income," computed without regard to the dividends paid deduction and Host Marriott's net capital gain, and (b) 90% (95% for taxable years ending before January 1, 2001) of the net income, after tax, if any, from foreclosure property, minus (ii) the sum of certain items of noncash income. In addition, if Host Marriott disposes of any built-in gain asset during the ten-year period beginning when Host Marriott acquired the asset, Host Marriott is required to distribute at least 90% (95% for taxable years ending before January 1, 2001) of the built-in gain, after tax, if any, recognized on the disposition of such asset. See "--General" above for a discussion of built-in gain assets. Such distributions must be paid in the taxable year to which they relate, or in the following taxable year if declared before Host Marriott timely files its tax return for such year and if paid on or before the first regular dividend payment date after such declaration. Host Marriott intends to make timely distributions sufficient to satisfy these annual distribution requirements. In this regard, the operating partnership's partnership agreement authorizes Host Marriott, as general partner, to take such steps as may be necessary to cause the operating partnership to distribute to its partners an amount sufficient to permit Host Marriott to meet these distribution requirements. To the extent that Host Marriott does not distribute all of its net capital gain or distributes at least 90% (95% for taxable years ending before January 1, 2001), but less than 100%, of its "REIT taxable income," as adjusted, it is subject to tax thereon at regular capital gain and ordinary corporate tax rates. Host Marriott, however, may designate some or all of its retained net capital gain, so that, although the designated amount will not be treated as distributed for purposes of this tax, a shareholder would include its proportionate share of such amount in income, as capital gain, and would be treated as having paid its proportionate share of the tax paid by Host Marriott with respect to such amount. The shareholder's basis in its capital stock of Host Marriott would be increased by the amount the shareholder included in income and decreased by the amount of the tax the shareholder is treated as having paid. Host Marriott would make an appropriate adjustment to its earnings and profits. For a more detailed description of the federal income tax consequences to a shareholder of such a designation, see "--Taxation of taxable U.S. shareholders generally" below. There is a significant possibility that Host Marriott's "REIT taxable income" will exceed its cash flow, due in part to certain "non-cash" or "phantom" income expected to be taken into account in computing Host Marriott's "REIT taxable income." Host Marriott anticipates, however, that it will generally have sufficient cash or liquid assets to enable it to satisfy the distribution requirements described above. It is possible, however, that Host Marriott, from time to time, may not have sufficient cash or other liquid assets to meet these distribution requirements. In such event, in order to meet the distribution requirements, Host Marriott may find it necessary to arrange for short-term, or possibly long-term, borrowings to fund required distributions and/or to pay dividends in the form of taxable stock dividends. Host Marriott calculates its "REIT taxable income" based upon the conclusion that the non-corporate subsidiaries of the operating partnership or the operating partnership itself, as applicable, is the owner of the hotels for federal income tax purposes. As a result, Host Marriott expects that the depreciation deductions with respect to the hotels will reduce its "REIT taxable income." This conclusion is consistent with the conclusion above that the leases entered into with the Crestline subsidiaries, all of which leases for full-service hotels but one were acquired by HMT Lessee, have been and will continue to be treated as true leases for federal income tax purposes. If the IRS were to challenge successfully this position, in addition to failing in all likelihood the 75% and 95% gross income tests described above, Host Marriott also might be deemed retroactively to have failed to meet the REIT distribution requirements and would have to rely on the payment of a "deficiency dividend" in order to retain its REIT status. S-70

Under certain circumstances, Host Marriott may be able to rectify a failure to meet the distribution requirement for a year by paying "deficiency dividends" to shareholders in a later year, which may be included in Host Marriott's deduction for dividends paid for the earlier year. Thus, Host Marriott may be able to avoid being taxed on amounts distributed as deficiency dividends; however, Host Marriott would be required to pay interest based upon the amount of any deduction taken for deficiency dividends. Furthermore, if Host Marriott should fail to distribute during each calendar year at least the sum of 85% of its REIT ordinary income for such year, 95% of its REIT capital gain income for such year, and any undistributed taxable income from prior periods, it would be subject to an excise tax. The excise tax would equal 4% of the excess of such required distribution over the sum of amounts actually distributed and amounts retained with respect to which the REIT pays federal income tax. Failure of Host Marriott to qualify as a REIT. If Host Marriott fails to qualify for taxation as a REIT in any taxable year, and if the relief provisions do not apply, Host Marriott will be subject to tax, including any applicable alternative minimum tax, on its taxable income at regular corporate rates. Distributions to shareholders in any year in which Host Marriott fails to qualify will not be deductible by Host Marriott nor will they be required to be made. As a result, Host Marriott's failure to qualify as a REIT would significantly reduce the cash available for distribution by Host Marriott to its shareholders and could materially reduce the value of its capital stock. In addition, if Host Marriott fails to qualify as a REIT, all distributions to shareholders will be taxable as ordinary income, to the extent of Host Marriott's current and accumulated E&P, although, subject to certain limitations of the Internal Revenue Code, corporate distributees may be eligible for the dividends received deduction with respect to these distributions. Unless entitled to relief under specific statutory provisions, Host Marriott also will be disqualified from taxation as a REIT for the four taxable years following the year during which qualification was lost. It is not possible to state whether in all circumstances Host Marriott would be entitled to such statutory relief. Tax aspects of Host Marriott's ownership of interests in the operating partnership General. Substantially all of Host Marriott's investments are held through the operating partnership, which holds the hotels either directly or through certain subsidiaries. In general, partnerships are "pass-through" entities that are not subject to federal income tax. Rather, partners are allocated their proportionate shares of the items of income, gain, loss, deduction and credit of a partnership, and are potentially subject to tax thereon, without regard to whether the partners receive a distribution from the partnership. Host Marriott includes in its income its proportionate share of the foregoing partnership items for purposes of the various REIT income tests and in the computation of its REIT taxable income. Moreover, for purposes of the REIT asset tests, Host Marriott includes its proportionate share of assets held through the operating partnership and certain of its subsidiaries. See "--Federal income taxation of Host Marriott--Ownership of partnership interests by a REIT" above. Entity classification. If the operating partnership or any non-corporate subsidiary were treated as an association, the entity would be taxable as a corporation and therefore would be subject to an entity level tax on its income. In such a situation, the character of Host Marriott's assets and items of gross income would change and could preclude Host Marriott from qualifying as a REIT (see "--Federal income taxation of Host Marriott--Asset tests applicable to REITs" and "--Income tests applicable to REITs" above). The entire discussion of the federal income tax consequences of the ownership of common stock is based on the assumption that the operating partnership and all of its non-corporate subsidiaries (other than HMT Lessee and any subsidiaries held by a non-controlled subsidiary or HMT Lessee) are classified as partnerships or disregarded as separate entities for federal income tax purposes. Pursuant to regulations under Section 7701 of the Internal Revenue Code, a partnership will be treated as a partnership for federal income tax purposes unless it elects to be treated as a corporation or would be treated as a corporation because it is a "publicly traded partnership." Neither the operating partnership nor any of the non-corporate subsidiaries (other than HMT Lessee, which will elect to be treated as a corporation and a taxable REIT subsidiary, effective January 1, S-71

2001) has elected or will elect to be treated as a corporation, and therefore, subject to the disclosure below, each will be treated as a partnership for federal income tax purposes (or, if such an entity has only one partner or member, disregarded entirely for federal income tax purposes). Pursuant to Section 7704 of the Internal Revenue Code, however, a partnership that does not elect to be treated as a corporation nevertheless will be treated as a corporation for federal income tax purposes if it is a "publicly traded partnership," unless at least 90% of its income consists of "qualifying income" within the meaning of that section. A "publicly traded partnership" is any partnership (i) the interests in which are traded on an established securities market or (ii) the interests in which are readily tradable on a "secondary market or the substantial equivalent thereof." Units of the operating partnership will not be traded on an established securities market. There is a significant risk, however, that after the right to redeem the units of the operating partnership becomes exercisable, such interests would be considered readily tradable on the substantial equivalent of a secondary market. In this regard, the income requirements generally applicable to REITs and the definition of "qualifying income" under Section 7704 of the Internal Revenue Code are similar in most key respects. There is one significant difference, however, that is relevant to the operating partnership. For a REIT, rent from a tenant does not qualify as "rents from real property" if the REIT and/or one or more actual or constructive owners of 10% or more of the REIT actually or constructively own 10% or more of the tenant (subject to an exception, applicable for taxable years beginning after December 31, 2000, for rents from a tenant that is a taxable REIT subsidiary); under Section 7704 of the Internal Revenue Code, rent from a tenant is not qualifying income if a partnership and/or one or more actual or constructive owners of 5% or more of the partnership actually or constructively own 10% or more of the tenant. A substantial majority of the operating partnership's income, for periods prior to the acquisition of the hotel leases by HMT Lessee, came from rent payments by subsidiaries of Crestline. Accordingly, because the Blackstone Entities, Host Marriott and any owner of 10% or more of Host Marriott would own or would be deemed to own 5% or more of the operating partnership, if the Blackstone Entities, Host Marriott and/or any owner of 10% or more of Host Marriott were to have owned or be deemed to own collectively 10% or more of Crestline, none of the rent from the Crestline lessees during those time periods would have been qualifying income for purposes of determining whether the operating partnership should be taxed as a corporation. In order to avoid this result, the Crestline articles of incorporation have expressly provided that no person (or persons acting as a group), including the Blackstone Entities, Host Marriott and any owner of 10% or more of Host Marriott, may own, actually and/or constructively, more than 9.8% by value of the equity in Crestline and the Crestline articles of incorporation contain self-executing mechanisms intended to enforce this prohibition. In addition, the operating partnership's partnership agreement prohibits any person, or persons acting as a group, or entity, other than an affiliate of the Blackstone Entities and Host Marriott, from owning, actually and/or constructively, more than 4.9% of the value of the operating partnership, and the Host Marriott charter prohibits any person, or persons acting as a group, or entity, including the Blackstone Entities and the Marriott family and their affiliated entities as a group, from, subject to certain limited exceptions, owning, actually and/or constructively, more than 9.8% of the lesser of the number or value of the total outstanding shares of common stock of Host Marriott. If these prohibitions were not enforced during the period that Crestline owned the lessees of Host Marriott's hotels, there is a significant likelihood that the operating partnership would have been treated as a corporation for federal income tax purposes if the operating partnership were considered a publicly traded partnership under the Internal Revenue Code. As described above, as a result of the passage of the REIT Modernization Act, for taxable years beginning after December 31, 2000, the operating partnership is able to lease its hotel properties to a taxable REIT subsidiary and the rents received from that subsidiary would not be disqualified from being "rents from real property" under the REIT rules by reason of the operating partnership's ownership interest in the subsidiary. See "--Federal income taxation of Host Marriott-- Income tests applicable to REITs" above. As noted above, effective January 1, 2001, HMT Lessee, a wholly owned subsidiary of Host Marriott that will elect to be treated as a taxable REIT subsidiary, purchased from Crestline the lessees of 112 of Host Marriott's hotels and the leasehold interests in an additional four hotels. It is unclear at this time whether the change in law pursuant to the REIT Modernization Act that permits a REIT to treat as "rents from real property" rents received from a related party tenant if such tenant is a taxable REIT S-72

subsidiary applies to such rents received by a partnership for purposes of determining "qualifying income." In the absence of definitive guidance on the matter, Host Marriott will take such actions, if any, that are necessary to prevent the operating partnership from being classified as a publicly traded partnership, including exercising its authority, as general partner, under the partnership agreement to impose limitations on the exercise of the right to redeem units of the operating partnership so that the operating partnership may qualify for certain safe harbors regarding transfers provided in the "publicly traded partnership" regulations. These limitations could adversely affect the interests of holders of units of the operating partnership. If, however, Host Marriott were not to take these steps (or the steps were ineffective in preventing the operating partnership from being classified as a publicly traded partnership under the applicable regulations), there would be a significant risk that the operating partnership could be treated as a corporation for federal income tax purposes. If the operating partnership were taxable as a corporation, most, if not all, of the tax consequences described herein would be inapplicable. In particular, Host Marriott would not qualify as a REIT because the value of Host Marriott's ownership interest in the operating partnership would exceed 5% of Host Marriott's assets and Host Marriott would be considered to hold more than 10% of the voting securities (and 10% of the value of the outstanding securities) of another corporation (see "--Federal income taxation of Host Marriott--Asset tests applicable to REITs" above). In this event, the value of Host Marriott common stock could be adversely affected (see "--Federal income taxation of Host Marriott--Failure of Host Marriott to qualify as a REIT" above). Allocations of operating partnership income, gain, loss and deduction. The partnership agreement of the operating partnership provides that if the operating partnership operates at a net loss, net losses shall be allocated to Host Marriott and the limited partners in proportion to their respective percentage ownership interests in the operating partnership, provided that net losses that would have the effect of creating a deficit balance in a limited partner's capital account as specially adjusted for such purpose ("Excess Losses") will be reallocated to Host Marriott, as general partner of the operating partnership. The partnership agreement also provides that, if the operating partnership operates at a net profit, net income shall be allocated first to Host Marriott to the extent of Excess Losses with respect to which Host Marriott has not previously been allocated net income. Any remaining net income shall be allocated in proportion to the respective percentage ownership interests of Host Marriott and the limited partners. Finally, the partnership agreement provides that if the operating partnership has preferred units of the operating partnership outstanding, income will first be allocated to such preferred units of the operating partnership to the extent necessary to reflect and preserve the economic rights associated with such preferred units of the operating partnership. Although a partnership agreement will generally determine the allocation of income and loss among partners, such allocations will be disregarded for tax purposes if they do not comply with the provisions of Section 704(b) of the Internal Revenue Code and the applicable regulations. Generally, Section 704(b) and the applicable regulations require that partnership allocations respect the economic arrangement of the partners. If an allocation is not recognized for federal income tax purposes, the item subject to the allocation will be reallocated in accordance with the partners' interests in the partnership, which will be determined by taking into account all of the facts and circumstances relating to the economic arrangement of the partners with respect to such item. The allocations of taxable income and loss provided for in the operating partnership partnership agreement and the partnership agreements and operating agreements of the non-corporate subsidiaries are intended to comply with the requirements of Section 704(b) of the Internal Revenue Code and the regulations promulgated thereunder. Tax allocations with respect to the hotels. Pursuant to Section 704(c) of the Internal Revenue Code, income, gain, loss and deduction attributable to appreciated or depreciated property, such as the hotels, that is contributed to a partnership in exchange for an interest in the partnership must be allocated in a manner such that the contributing partner is charged with, or benefits from, respectively, the difference between the adjusted tax basis and the fair market value of such property at the time of contribution associated with the property at the time of the contribution. This difference is known as built-in gain. The operating partnership agreement S-73

requires that such allocations be made in a manner consistent with Section 704(c) of the Internal Revenue Code. In general, the partners of the operating partnership, including Host Marriott, who contributed depreciated assets having built-in gain are allocated depreciation deductions for tax purposes that are lower than such deductions would be if determined on a pro rata basis. Thus, the carryover basis of the contributed assets in the hands of the operating partnership may cause Host Marriott to be allocated lower depreciation and other deductions, and therefore to be effectively allocated more income, which might adversely affect Host Marriott's ability to comply with the REIT distribution requirements and/or cause a higher proportion of Host Marriott's distributions to its shareholders to be taxed as dividends. See "--Federal income taxation of Host Marriott--Annual distribution requirements applicable to REITs" above. In addition, in the event of the disposition of any of the contributed assets which have built-in gain, all income attributable to the built-in gain generally will be allocated to the contributing partners, even though the proceeds of such sale would be allocated proportionately among all the partners and likely would be retained by the operating partnership, rather than distributed. Thus, if the operating partnership were to sell a hotel with built-in gain that was contributed to the operating partnership by Host Marriott's predecessors or Host Marriott, Host Marriott generally would be allocated all of the income attributable to the built-in gain, which could exceed the economic or book income allocated to it as a result of such sale. Such an allocation might cause Host Marriott to recognize taxable income in excess of cash proceeds, which might adversely affect Host Marriott's ability to comply with the REIT distribution requirements. In addition, Host Marriott will be subject to a corporate level tax on such gain to the extent the gain is recognized prior to January 1, 2009. See "--Federal income taxation of Host Marriott--Annual distribution requirements applicable to REITs" and "--Federal income taxation of Host Marriott--General" above. It should be noted in this regard that as the general partner of the operating partnership, Host Marriott will determine whether or not to sell a hotel contributed to the operating partnership by Host Marriott. The operating partnership and Host Marriott generally use the traditional method, with a provision for a curative allocation of gain on sale to the extent prior allocations of depreciation with respect to a specific hotel were limited by the "ceiling rule" applicable under the traditional method, to account for built-in gain with respect to the hotels contributed to the operating partnership in connection with the REIT conversion. This method is generally a more favorable method for accounting for built-in gain from the perspective of those partners, including Host Marriott, who received units of the operating partnership in exchange for property with a low basis relative to value at the time of the REIT conversion and is a less favorable method from the perspective of those partners who contributed cash or "high basis" assets to the operating partnership, including Host Marriott, to the extent it contributes cash to the operating partnership. Any property purchased by the operating partnership subsequent to the REIT conversion will initially have a tax basis equal to its fair market value, and Section 704(c) of the Internal Revenue Code will not apply. Other tax consequences for Host Marriott and its shareholders Host Marriott and its shareholders are subject to state or local taxation in various state or local jurisdictions, including those in which the operating partnership or Host Marriott's shareholders transact business or reside. The state and local tax treatment of Host Marriott and its shareholders may not conform to the federal income tax consequences discussed above. Consequently, prospective shareholders of Host Marriott should consult their own tax advisors regarding the effect of state and local tax laws on an investment in Host Marriott. A portion of the cash to be used by Host Marriott to fund distributions comes from dividends from the non-controlled subsidiaries and HMT Lessee and, in some cases, interest on notes held by the operating partnership. Each non- controlled subsidiary and HMT Lessee is subject to federal and state income tax at the full applicable corporate rates. As described above in "--Federal income taxation of Host Marriott--Income tests applicable to REITs" and "--Asset tests applicable to REITs" above, both of the non-controlled subsidiaries and HMT Lessee will S-74

elect to be treated as a taxable REIT subsidiary for years commencing after December 31, 2000. As a taxable REIT subsidiary, each of the non-controlled subsidiaries and HMT Lessee will be fully taxable as a corporation and will be subject to certain rules intended to restrict its ability to reduce its tax liability. For a more detailed discussion of taxable REIT subsidiaries, see "-- Federal income taxation of Host Marriott--Qualification of an entity as a taxable REIT subsidiary" above. To the extent that any of the non-controlled subsidiaries or HMT Lessee is required to pay federal, state or local taxes, Host Marriott will receive less dividend income from the relevant entity and will have less cash available for distribution to shareholders. Taxation of Taxable U.S. Shareholders When we use the term "U.S. shareholder", we mean a holder of shares of Class C preferred stock who is, for United States federal income tax purposes: . a citizen or resident of the United States, . a corporation, partnership, or other entity treated as a corporation or partnership for United States federal income tax purposes, created or organized in or under the laws of the United States or of a state thereof or in the District of Columbia, unless, in the case of a partnership, Treasury Regulations provide otherwise, . an estate the income of which is subject to United States federal income taxation regardless of its source or . a trust whose administration is subject to the primary supervision of a United States court and which has one or more United States persons who have the authority to control all substantial decisions of the trust. Notwithstanding the preceding sentence, to the extent provided in Treasury Regulations, some trusts in existence on August 20, 1996, and treated as United States persons prior to this date that elect to continue to be treated as United States persons, shall also be considered U.S. shareholders. Distributions Generally. Distributions out of our current or accumulated earnings and profits, other than capital gain dividends discussed below, will constitute dividends taxable to our taxable U.S. shareholders as ordinary income. As long as we qualify as a real estate investment trust, these distributions will not be eligible for the dividends-received deduction in the case of U.S. shareholders that are corporations. For purposes of determining whether distributions to holders of our Class C preferred stock are made out of our current or accumulated earnings and profits for federal income tax purposes, our earnings and profits will be allocated first to the Class C preferred stock, Class B preferred stock and Class A preferred stock on a pro rata basis and then to our common stock. To the extent that we make distributions, other than capital gain dividends discussed below, in excess of our current and accumulated earnings and profits, these distributions will be treated first as a tax-free return of capital to each U.S. stockholder. This treatment will reduce the adjusted tax basis which each U.S. shareholder has in his Class C preferred stock by the amount of the distribution in excess of earnings and profits, but not below zero. Distributions in excess of a U.S. shareholder's adjusted tax basis in his shares will be taxable as capital gain. Such gain will be taxable as long-term capital gain if the shares have been held for more than one year. Dividends we declare in October, November, or December of any year and payable to a shareholder of record on a specified date in any of these months will be treated as both paid by us and received by the shareholder on December 31 of that year, provided we actually pay the dividend on or before January 31 of the following year. Shareholders may not include in their own income tax returns any of our net operating losses or capital losses. Capital Gain Distributions. Distributions that we properly designate as capital gain dividends will be taxable to our taxable U.S. shareholders as gain, to the extent that such gain does not exceed our actual net S-75

capital gain for the taxable year from the sale or disposition of capital assets. Depending on the characteristics of the assets which produced these gains, and on specific designations, if any, which we make, these gains may be taxable to non-corporate U.S. shareholders at a 20% or 25% rate. U.S. shareholders that are corporations may, however, be required to treat up to 20% of some capital gain dividends as ordinary income. If we properly designate any portion of a dividend as a capital gain dividend, then any portion of the total capital gain dividends paid or made available to holders of all classes of our stock for the year shall be allocable to the holders of Class C preferred stock in proportion to the amount that the total dividends, as determined for federal income tax purposes, paid or made available to the holders of the Class C preferred stock for the year bears to the total dividends paid or made available to holders of all classes of our stock for the year. Passive Activity Losses and Investment Interest Limitations. Distributions we make and gain arising from the sale or exchange by a U.S. shareholder of shares of Class C preferred stock will not be treated as passive activity income. As a result, U.S. shareholders generally will not be able to apply any "passive losses" against this income or gain. Distributions we make, to the extent they do not constitute a return of capital, generally will be treated as investment income for purposes of computing the investment interest limitation. Gain arising from the sale or other disposition of shares of Class C preferred stock, however, may not be treated as investment income depending upon your particular situation. Retention of Net Long-Term Gains. We may elect to retain, rather than distribute as a capital gain dividend, our net long-term capital gains. If we make this election, we would pay tax on our retained net long-term capital gains. In addition, to the extent we designate, a U.S. shareholder generally would: . include its proportionate share of our undistributed long-term capital gains in computing its long-term capital gains in its return for its taxable year in which the last day of our taxable year falls; . be deemed to have paid the capital gains tax imposed on us on the designated amounts included in the U.S. shareholder's long-term capital gains; . receive a credit or refund for the amount of tax deemed paid by it; . increase the adjusted basis of its shares of Class C preferred stock by the difference between the amount of includable gains and the tax deemed to have been paid by it; and . in the case of U.S. shareholder that is a corporation, appropriately adjust its earnings and profits for the retained capital gains as required by Treasury Regulations to be prescribed by the Internal Revenue Service. Dispositions of Class C Preferred Stock. If you are a U.S. shareholder and you sell or dispose of your shares of Class C preferred stock to a person other than Host Marriott, you will recognize gain or loss for federal income tax purposes in an amount equal to the difference between (i) the amount of cash and the fair market value of any property you receive on the sale or other disposition, less any portion thereof attributable to accumulated and declared but unpaid distributions that you are entitled to receive, which would have been characterized as a dividend to the extent of our current and accumulated earnings and profits, and (ii) your adjusted basis in the shares of Class C preferred stock for tax purposes. This gain or loss will be capital gain or loss. This gain or loss, except as provided below, will be long-term capital gain or loss if you have held the Class C preferred stock for more than one year. In general, if you are a U.S. shareholder and you recognize loss upon the sale or other disposition of shares of Class C preferred stock that you have held for six months or less, the loss you recognize will be treated as a long- term capital loss, to the extent you received distributions from us which were required to be treated as long-term capital gains. Redemption of Class C Preferred Stock. A redemption of shares of Class C preferred stock for cash will be a taxable event. A redemption of Class C preferred stock for cash generally will be treated as a sale or exchange if the U.S. shareholder does not own, actually or constructively, within the meaning of Section 318 of the Internal Revenue Code, any of our stock other than the stock that is redeemed. If the U.S. shareholder owns, actually or constructively, other stock, including Class C preferred stock that is not redeemed, a redemption of Class C S-76

preferred stock may be treated as a dividend to the extent of our current or accumulated earnings and profits for federal income tax purposes. Dividend treatment, however, would not apply if the redemption: . is "substantially disproportionate" with respect to the shareholder under section 302(b)(2) of the Internal Revenue Code; or . is "not essentially equivalent to a dividend" with respect to the shareholder under section 302(b)(1) of the Internal Revenue Code. In determining whether these tests have been met, a U.S. shareholder must take into account not only stock he actually owns, but also stock he constructively owns within the meaning of Section 318 of the Internal Revenue Code. A distribution to a shareholder is "not essentially equivalent to a dividend" if it results in a "meaningful reduction" in the shareholder's interest in our stock. If, as a result of a redemption of the Class C preferred stock, a shareholder whose relative stock interest in us is minimal and who exercises no control over our corporate affairs suffers a significant reduction in its proportionate interest in us, taking into account constructive ownership, that shareholder should be regarded as having suffered a meaningful reduction in its interest in our stock. There can be no certainty, however, as to when a meaningful reduction has occurred because the applicable test is not based on numerical criteria. Satisfaction of the "substantially disproportionate" exception is dependent upon compliance with the objective tests set forth in section 302(b)(2) of the Internal Revenue Code. If the redemption of Class C preferred stock is not treated as a distribution taxable as a dividend, the redemption of the Class C preferred stock would be taxed as described above under the heading "Dispositions of Class C Preferred Stock." Backup Withholding We report to our U.S. shareholders and the Internal Revenue Service the amount of dividends paid during each calendar year, and the amount of any tax withheld. Under the backup withholding rules, a shareholder may be subject to backup withholding at the rate of 31% with respect to dividends paid unless the holder is a corporation or is otherwise exempt and, when required, demonstrates this fact, or provides a taxpayer identification number, certifies as to no loss of exemption from backup withholding, and otherwise complies with the backup withholding rules. A U.S. shareholder that does not provide us with his correct taxpayer identification number may also be subject to penalties imposed by the Internal Revenue Service. Backup withholding is not an additional tax. Any amount paid as backup withholding will be creditable against the stockholder's income tax liability. In addition, we may be required to withhold a portion of capital gain distributions to any shareholders who fail to certify their non-foreign status. Taxation of Tax-Exempt Shareholders The Internal Revenue Service has ruled that amounts distributed as dividends by qualified real estate investment trust do not constitute unrelated business taxable income when received by a tax-exempt entity. Based on that ruling, except as described below, dividend income from us and gain arising upon your sale of Class C preferred stock generally will not be unrelated business taxable income to a tax-exempt shareholder. This income or gain will be unrelated business taxable income, however, if the tax-exempt shareholder holds its Class C preferred stock as "debt financed property" within the meaning of the Internal Revenue Code or if the Class C preferred stock is used in a trade or business of the tax-exempt shareholder. Generally, debt financed property is property, the acquisition or holding of which was financed through a borrowing by the tax-exempt shareholder. For tax-exempt shareholders which are social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts, and qualified group legal services plans exempt from federal income taxation under Sections 501(c)(7), (c)(9), (c)(17) and (c)(20) of the Internal Revenue Code, respectively, income from an investment in our Class C preferred stock will constitute unrelated business taxable income unless the organization is able to properly claim a deduction for amounts set aside or placed in reserve for specific purposes so as to offset the income generated by its investment in our Class C preferred stock. These prospective investors should consult their tax advisors concerning these "set aside" and reserve requirements. S-77

Notwithstanding the above, however, a portion of the dividends paid by a "pension-held real estate investment trust" shall be treated as unrelated business taxable income as to any trust which: .is described in Section 401(a) of the Internal Revenue Code; .is tax-exempt under Section 501(a) of the Internal Revenue Code; and .holds more than 10%, by value, of the interests in the real estate investment trust. Tax-exempt pension funds that are described in Section 401(a) of the Internal Revenue Code and exempt from tax under Section 501(a) of the Internal Revenue Code are referred to below as "qualified trusts." A real estate investment trust is a "pension-held real estate investment trust" if: . it would not have qualified as a real estate investment trust but for the fact that Section 856(h)(3) of the Internal Revenue Code provides that stock owned by qualified trusts shall be treated, for purposes of the "not closely held" requirement, as owned by the beneficiaries of the trust, rather than by the trust itself; and . either at least one such qualified trust holds more than 25%, by value, of the interests in the real estate investment trust, or one of more such qualified trusts, each of which owns more than 10%, by value, of the interests in the real estate investment trust, holds in the aggregate more than 50%, by value, of the interests in the real estate investment trust. The percentage of any real estate investment trust dividend treated as unrelated business taxable income is equal to the ratio of: . the unrelated business taxable income earned by the real estate investment trust, treating the real estate investment trust as if it were a qualified trust and therefore required to pay tax on unrelated business taxable income, to . the total gross income of the real estate investment trust. A de minimis exception applies where the percentage is less than 5% for any year. The provisions requiring qualified trusts to treat a portion of real estate investment trust distributions as unrelated business taxable income will not apply if the real estate investment trust is able to satisfy the "not closely held" requirement without relying upon the "look-through" exception with respect to qualified trusts. Based on the current estimated ownership of our stock and as a result of limitations on the transfer and ownership of our stock contained in our charter, we should not be classified as a "pension-held real estate investment trust." Taxation of Non-U.S. Shareholders The preceding discussion does not address the rules governing United States federal income taxation of the ownership and disposition of Class C preferred stock by persons that are non-U.S. shareholders. When we use the term "non-U.S. shareholder" we mean shareholders who are not U.S. shareholders. In general, non-U.S. shareholders may be subject to special tax withholding requirements on distributions from us and with respect to their sale or other disposition of our Class C preferred stock, except to the extent reduced or eliminated by an income tax treaty between the United States and the non-U.S. shareholder's country. A non-U.S. shareholder who is a shareholder of record and is eligible for reduction or elimination of withholding must file an appropriate form with us in order to claim such treatment. Non-U.S. shareholders should consult their own tax advisors concerning the federal income tax consequences to them of an acquisition of shares of Class C preferred stock, including the federal income tax treatment of dispositions of interests in and the receipt of distributions from us. Other Tax Consequences Your state and local tax treatment may not conform to the federal income tax consequences summarized above. Consequently, you should consult your tax advisor regarding the effect of state and local tax laws on an investment in our shares. S-78

The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the shares of Class C preferred stock offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the shares of Class C preferred stock offered by this prospectus supplement if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters' over-allotment option described below. The underwriters initially propose to offer part of the shares of Class C preferred stock directly to the public at the public offering price set forth on the cover page of this prospectus supplement and part to certain dealers at a price that represents a concession not in excess of $.50 a share under the public offering price. Any underwriter may allow, and such dealers may re- allow, a concession not in excess of $.45 a share to other underwriters or to certain dealers. After the initial offering of the shares of Class C preferred stock, the offering price and other selling terms may from time to time be varied by the representatives. S-79

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to an aggregate of 780,000 additional shares of Class C preferred stock at the public offering price set forth on the cover page of this prospectus supplement less underwriting discounts and commissions. The underwriters may exercise this option solely for the purpose of covering over-allotments, if any, made in connection with the offering of the shares of Class C preferred stock offered by this prospectus supplement. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional shares of Class C preferred stock as the number set forth next to the underwriter's name in the preceding table bears to the total number of shares of Class C preferred stock listed next to the names of all underwriters in the preceding table. If the underwriters' option is exercised in full, the total price to public would be $149,500,000, the total underwriting discounts and commissions would be $4,858,750 and the total proceeds to us would be $144,641,250. Underwriting discounts and commissions for sales of 375,000 or more shares of Class C preferred stock to a single purchaser will be $.50 per share. If any of these sales occurs, the total underwriting discounts and commissions will be less than the amounts set forth on the cover page of this prospectus supplement and, if applicable, in the preceding sentence. The Class C preferred stock has been approved for listing, subject to official notice of issuance, on the New York Stock Exchange under the symbol "HMTPrC". We expect that trading of shares of Class C preferred stock on the NYSE will commence within the 30-day period after initial delivery of the shares. The underwriters have advised us that they intend to make a market in the shares of Class C preferred stock prior to the commencement of trading on the NYSE. The underwriters will have no obligation to make a market in the shares of Class C preferred stock, however, and may cease market-making activities, if commenced, at any time. We have agreed that, without the prior written consent of Morgan Stanley & Co. Incorporated on behalf of the underwriters, we will not, during the period ending 30 days after the date of this prospectus supplement: . offer, issue, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any shares of Class C preferred stock or other preferred stock, any shares of any other class or series of our capital stock which is substantially similar to the Class C preferred stock, any preferred securities of a subsidiary trust or similar financing vehicle or any depositary shares or depositary receipts representing or evidencing any of the foregoing, or any securities convertible into or exercisable or exchangeable for any of the foregoing, or . enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Class C preferred stock or other preferred stock, any shares of any other class or series of our capital stock which is substantially similar to the Class C preferred stock, any preferred securities of a subsidiary trust or similar financing vehicle or any depositary shares or depositary receipts representing or evidencing any of the foregoing or any securities convertible into or exercisable or exchangeable for any of the foregoing; whether any transaction described above is to be settled by delivery of Class C preferred stock, other securities, in cash or otherwise. The restrictions described in this paragraph do not apply to the sale of shares of Class C preferred stock to the underwriters. In order to facilitate the offering of the shares of Class C preferred stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the shares of Class C preferred stock. Specifically, the underwriters may over-allot in connection with the offering, creating a short position in the shares of Class C preferred stock for their own account. In addition, to cover over-allotments or to stabilize the price of the shares of Class C preferred stock, the underwriters may bid for, and purchase, shares of Class C preferred stock in the open market. Finally, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the shares of Class C preferred stock in the offering, if the syndicate repurchases previously distributed shares of Class C preferred stock in transactions to cover syndicate S-80

short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the shares of Class C preferred stock above independent market levels. The underwriters are not required to engage in these activities, and may end any of these activities at any time. Certain of the underwriters and their affiliates have from time to time provided investment banking and other services to us, including acting as underwriters for offerings by us or our subsidiaries, and may continue to do so in the future. In that regard, affiliates of certain of the underwriters act as agents and/or lenders under the operating partnership's bank credit facility and, in addition, affiliates of certain underwriters provided the operating partnership and its subsidiaries with certain mortgage financing. We and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act of 1933. In addition, we have agreed to pay expenses incurred by the underwriters in connection with the offering of Class C preferred stock in an amount not to exceed $370,000. LEGAL MATTERS Certain legal matters in connection with the offering of the Class C preferred stock will be passed upon for us by internal counsel to Host Marriott and by Latham & Watkins, Washington, D.C. Certain Maryland law matters relating to the offering will be passed upon by Ballard Spahr Andrews & Ingersoll, LLP, special Maryland counsel to Host Marriott. Brown & Wood LLP, San Francisco, California, will act as counsel for the underwriters.

As used herein and in the accompanying prospectus supplement, "Host Marriott" means Host Marriott Corporation, a Maryland corporation, and/or its subsidiary Host Marriott, L.P., a Delaware limited partnership and its subsidiaries. RISK FACTORS Prospective investors should carefully consider, among other factors, the material risks described below. We Do Not Control Our Hotel Operations Because federal income tax laws restrict real estate investment trusts from deriving revenues directly from operating a hotel, we do not operate any of our hotels. Instead, we lease virtually all of our hotels to subsidiaries of Crestline Capital Corporation which, in turn, retain managers to manage our hotels pursuant to management agreements. Under the hotel leases, we have little influence over how the lessees operate our hotels. Similarly, we have virtually no influence over how the managers manage our hotels. As a result, our revenue depends upon the ability of the lessees and the managers to operate and manage our hotels. We have no recourse if we believe that the hotel managers do not maximize the revenues from our hotels, which in turn will maximize the rental payments we receive under the leases. We may seek redress under most leases only if the lessee violates the terms of the lease and then only to the extent of the remedies set forth in the lease. We may terminate a lease if the lessee defaults, but terminating a lease could impair our ability to qualify as a REIT for federal income tax purposes unless another suitable lessee is found. We Do Not Control Certain Assets Held by the Non-Controlled Subsidiaries We own economic interests in certain taxable corporations, which we refer to as the "non-controlled subsidiaries," that hold various assets not exceeding, in the aggregate, 15% in value of our assets. These assets consist primarily of interests in hotels which are not leased, certain furniture, fixtures and equipment ("FF&E") used in our hotels, and certain international hotels that could jeopardize our REIT status. Although we own 95% of the economic interests of the non-controlled subsidiaries, the Host Marriott Statutory Employee/Charitable Trust owns all of the voting common stock, which represents the remaining 5% of the economic interest, of the non-controlled subsidiaries. This voting stockholder elects the directors who are responsible for overseeing the operations of the non-controlled subsidiaries. As a result, we have no control over the operation or management of the hotels or other assets owned by the non-controlled subsidiaries, even though we depend upon the non-controlled subsidiaries for a significant portion of our revenues. We Are Dependent on the Lessees' Rent Payments As Our Primary Source of Revenues Subsidiaries of Crestline lease virtually all of our hotels. The lessees' rent payments are the primary source of our revenues. Crestline guarantees the obligations of its subsidiaries under the hotel leases, but Crestline's liability is limited to a relatively small portion of the aggregate rent obligation of its subsidiaries. Crestline's and each of its subsidiaries' ability to meet its obligations under the leases will determine the amount of our revenue and, likewise, our ability to make distributions to stockholders. We have no control over Crestline or any of its subsidiaries and cannot assure you that Crestline or any of its subsidiaries will have sufficient assets, income and access to financing to enable them to satisfy their obligations under the leases or to make payments of fees under the management agreements. Because of our dependence on Crestline, our credit rating will be affected by its general creditworthiness. We Are Dependent on the Hotel Managers to Operate the Hotels Effectively Our revenue will be affected by the performance of the managers of our hotels. It also will be affected by the relationships between the managers and the lessees. Their decisions involving hotel management may not 2

necessarily be in our best interests, and disagreements between them could adversely affect us. We have no control over these relationships. Moreover, each lessee's ability to pay rent accrued under its lease depends to a large extent on the ability of the hotel manager to operate the hotel effectively and to generate gross sales in excess of its operating expenses. Our rental income from the hotels may therefore be adversely affected if the managers fail to provide quality services and amenities and competitive room rates at our hotels or fail to maintain the quality of the hotel brand names. Although the lessees have primary liability under the management agreements while the leases are in effect, we remain liable under the leases for all obligations that the lessees do not perform. Our Revenues and the Value of Our Properties Could be Adversely Affected by Conditions Affecting the Lodging Industry If our assets do not generate income sufficient to pay our expenses, service our debt and maintain our properties, we will be unable to make expected distributions to our stockholders. Factors that could adversely affect our revenues and the economic performance and value of our properties include: . changes in the national, regional and local economic climate, . local conditions such as an oversupply of hotel properties or a reduction in demand for hotel properties, . the attractiveness of our hotels to consumers and competition from comparable hotels, . the quality, philosophy and performance of the hotel managers (primarily Marriott International, Inc.), . the ability of any hotel lessee to maximize rental payments, . changes in room rates and increases in operating costs due to inflation and other factors and . the need to periodically repair and renovate our hotels. Our Expenses May Remain Constant Even If Our Revenues Drop The expenses of owning a property are not necessarily reduced when circumstances such as market factors and competition cause a reduction in income from the property. If a property is mortgaged and we are unable to meet the mortgage payments, the lender could foreclose and take the property. Our financial condition and ability to service debt and make distributions to our stockholders could be adversely affected by: . interest rate levels, . the availability of financing, . the cost of compliance with government regulation, including zoning and tax laws and . changes in laws and governmental regulations, including those governing usage, zoning and taxes. New Acquisitions May Fail to Perform as Expected and We May Be Unable to Make Any Acquisitions We intend to acquire additional full-service hotels and other types of real estate. Newly acquired properties may fail to perform as expected, which could adversely affect our financial condition. We may underestimate the costs necessary to bring an acquired property up to standards established for its intended market position. We expect to acquire hotels and other types of real estate with cash from secured or unsecured financings and proceeds from offerings of equity or debt, to the extent available. We may not be in a position or have the opportunity in the future to make suitable property acquisitions on favorable terms. In addition, we cannot guarantee that the leases for newly acquired hotels will be as favorable to us as the Leases. 3

Competition for Acquisitions May Result in Increased Prices for Hotels Other major investors with significant capital compete with us for attractive investment opportunities. These competitors include other REITs and hotel companies, investment banking firms and private institutional investment funds. This competition may increase prices for hotel properties, thereby decreasing the potential return on our investment. The Seasonality of the Hotel Industry May Affect the Ability of the Lessees to Make Timely Rent Payments The seasonality of the hotel industry may, from time to time, affect either the amount of rent that accrues under the hotel leases or the ability of the lessees to make timely rent payments under the leases. A lessee's or Crestline's inability to make timely rent payments to us could adversely affect our financial condition and ability to service debt and make distributions to our stockholders. We May Be Unable to Sell Properties When Appropriate Because Real Estate Investments Are Illiquid Real estate investments generally cannot be sold quickly. We may not be able to vary our portfolio promptly in response to economic or other conditions. This inability to respond promptly to changes in the performance of our investments could adversely affect our financial condition and ability to service debt and make distributions to our stockholders. We May Be Unable to Renew Leases or Find Other Lessees Our current hotel leases have terms of seven to ten years. There can be no assurance that the affected hotels will be relet to Crestline or the current lessees, or if relet, will be relet on terms as favorable to us. If our hotels are not relet, we will be required to find other lessees who meet certain requirements of the management agreements and of the REIT tax rules. We cannot assure you that we would be able to find satisfactory lessees or that the terms of any new leases would be as favorable as under the current leases. Failure to find satisfactory lessees could cause us to lose our REIT status, and failure to enter leases on satisfactory terms could result in reduced cash available for distribution. Terms of the Hotel Ground Leases May Adversely Affect Our Revenues As of December 30, 1998, we lease 54 of our hotels pursuant to ground leases. These ground leases generally require increases in ground rent payments every five years. Our ability to make cash distributions to our stockholders could be adversely affected to the extent that the rents payable by the lessees under the leases do not increase at the same or a greater rate as the increases under the ground leases. In addition, if we were to sell a hotel encumbered by a ground lease, the buyer would have to assume the ground lease, which could result in a lower sales price. Some Potential Losses Are Not Covered By Insurance We carry comprehensive liability, fire, flood, extended coverage and rental loss (for rental losses extending up to 12 months) insurance with respect to all of our hotels. We believe the policy specifications and insured limits of these policies are of the type customarily carried for similar hotels. Certain types of losses, such as from earthquakes and environmental hazards, however, may be either uninsurable or too expensive to justify insuring against. Should an uninsured loss or a loss in excess of insured limits occur, we could lose all or a portion of the capital we have invested in a hotel, as well as the anticipated future revenue from the hotel. In such an event, we might nevertheless remain obligated for any mortgage debt or other financial obligations related to the property. 4

Leases Could Impair the Sale or Other Disposition of Our Hotels Each lease with a subsidiary of Crestline generally requires us to make a termination payment to the lessee if we terminate the lease prior to the expiration of its term. A termination payment is required even if we terminate a lease because of a change in the federal income tax laws that either would make continuation of the lease jeopardize our REIT status or would enable us to operate our hotels ourselves. The termination fee generally is equal to the fair market value of the lessee's leasehold interest in the remaining term of the lease, which could be a significant amount. In addition, if we decide to sell a hotel, we may be required to terminate its lease, and the payment of the termination fee under such circumstances could impair our ability to sell the hotel and would reduce the net proceeds of any sale. Management Agreements Could Impair the Sale or Other Disposition of Our Hotels Under the terms of the management agreements, we generally may not sell, lease or otherwise transfer the hotels unless the transferee assumes the related management agreements and meets certain other conditions. Our ability to finance, refinance or effect a sale of any of the properties managed by Marriott International or another manager may, depending upon the structure of such transactions, require the manager's consent. If Marriott International or other manager did not consent, we would be prohibited from consummating the financing, refinancing or sale without breaching the management agreement. The Acquisition Contracts Relating to Certain Hotels Limit Our Ability to Sell or Refinance Such Hotels For reasons relating to federal income tax considerations of the former owners of certain of our hotels, we have agreed to restrictions on selling certain hotels or repaying or refinancing the mortgage debt thereon for lock- out periods which vary depending on the hotel. We anticipate that, in certain circumstances, we may agree to similar restrictions in connection with future hotel acquisitions. As a result, even if it were in our best interests to sell such hotels or refinance their mortgage debt, it may be difficult or impossible to do so during their respective lock-out periods. Marriott International's and Crestline's Operation of Their Respective Businesses Could Result in Decisions Not in Our Best Interest Marriott International, a public company in the business of hotel management, manages a significant number of our hotels. In addition, Marriott International manages hotels owned by others that compete with our hotels. As a result, Marriott International may make decisions regarding competing lodging facilities which it manages that would not necessarily be in our best interests. Further, J.W. Marriott, Jr., a member of our Board of Directors, and Richard E. Marriott, our Chairman of the Board and J.W. Marriott, Jr.'s brother, serve as directors, and, in the case of J.W. Marriott, Jr., also an officer, of Marriott International. As of December 30, 1998, J.W. Marriott, Jr. and Richard E. Marriott also beneficially own approximately 10.6% and 10.3%, respectively, of the outstanding shares of common stock of Marriott International, and will beneficially own approximately 6.1% and 6.0%, respectively, of the outstanding shares of common stock of Crestline, but neither will serve as an officer or director of Crestline. As a result, J.W. Marriott, Jr. and Richard E. Marriott have potential conflicts of interest when making decisions regarding Marriott International, including decisions relating to the management agreements involving the hotels, Marriott International's management of competing lodging properties and Crestline's leasing and other businesses. The Boards of Directors of both Host Marriott and Marriott International follow appropriate policies and procedures to limit the involvement of Messrs. J.W. Marriott, Jr. and Richard E. Marriott in conflict situations, including requiring them to abstain from voting as directors of either Host Marriott or Marriott International or their subsidiaries on certain matters which present a conflict between the companies. If appropriate, these policies and procedures will apply to other directors and officers. 5

Provisions of Our Charter and Bylaws Could Inhibit Changes in Control Certain provisions of our charter and bylaws may delay or prevent a change in control of Host Marriott or other transaction that could provide our stockholders with a premium over the then-prevailing market price of their shares or which might otherwise be in their best interests. These include a staggered Board of Directors and the ownership limit described below. Also, any future class or series of stock may have certain voting provisions that could delay or prevent a change in control or other transaction that might involve a premium price or otherwise be good for our stockholders. The Marriott International Purchase Right May Discourage a Takeover of Host Marriott Marriott International has the right to purchase up to 20% of each class of our outstanding voting shares at the then fair market value upon the occurrence of certain change of control events involving Host Marriott. We refer to this right as the "Marriott International purchase right." The Marriott International purchase right will continue in effect until June 2017, subject to certain limitations intended to protect the our REIT status. The Marriott International purchase right may have the effect of discouraging a takeover of Host Marriott, because any person considering acquiring a substantial or controlling block of our common stock will face the possibility that its ability to obtain or exercise control would be impaired or made more expensive by the exercise of the Marriott International purchase right. We Have Adopted Maryland Law Limitations on Changes in Control Maryland corporate law prohibits certain "business combinations" between a Maryland corporation and any person who owns 10% or more of the voting power of the corporation's then outstanding shares of stock (an "Interested Stockholder") or an affiliate of the Interested Stockholder unless a business combination is approved by the board of directors any time before an Interested Stockholder first becomes an Interested Stockholder. The prohibition lasts for five years after the Interested Stockholder becomes an Interested Stockholder. Thereafter, any such business combination must be approved by stockholders under certain special voting requirements. We will be subject to such provisions although we may elect to "opt-out" in the future. As a result, a change in control of Host Marriott or other transaction that could provide our stockholders with a premium over the then-prevailing market price of their shares or which might otherwise be in their best interests may be prevented or delayed. Our Board of Directors has exempted from this statute the acquisition of shares by Marriott International pursuant to the terms of the Marriott International purchase right as well as any other transactions involving Host Marriott and Marriott International or our respective subsidiaries, or J.W. Marriott, Jr. or Richard E. Marriott, provided that, if any such transaction is not in the ordinary course of business, it must be approved by a majority of our directors present at a meeting at which a quorum is present, including a majority of the disinterested directors, in addition to any vote of stockholders required by other provisions of Maryland corporate law. Maryland Control Share Acquisition Law Could Delay or Prevent a Change in Control Under Maryland corporate law, unless a corporation elects not to be subject thereto, "control shares" acquired in a "control share acquisition" have no voting rights except to the extent approved by stockholders by a vote of two- thirds of the votes entitled to be cast on the matter, excluding shares owned by the acquiror and by officers or directors who are employees of the corporation. "Control shares" are voting shares which would entitle the acquiror to exercise voting power in electing directors within certain specified ranges of voting power. A "control share acquisition" means the acquisition of control shares, subject to certain exceptions. We are subject to these control share provisions of Maryland law and, as a result, a change in control of Host Marriott or other transaction that could provide our stockholders with a premium over the then-prevailing market price of their shares or which might otherwise be in their best interests may be delayed or prevented. Our bylaws contain an exemption from this statute for any shares acquired by Marriott International, together with its successors and permitted assignees, pursuant to the Marriott International purchase right. 6

We Have Adopted a Rights Agreement Which Could Delay or Prevent a Change in Control Our Rights Agreement provides, among other things, that upon the occurrence of certain events, stockholders will be entitled to purchase shares of our stock, subject to the ownership limit. These purchase rights would cause substantial dilution to a person or group that acquires or attempts to acquire 20% or more of our common stock on terms not approved by the Board of Directors and, as a result, could delay or prevent a change in control of Host Marriott or other transaction that could provide our stockholders with a premium over the then-prevailing market price of their shares or which might otherwise be in their best interests. See "Description of Common Stock--Stockholder Rights Plan/Preferred Stock Purchase Rights." We Have a Stock Ownership Limit Primarily for REIT Tax Purposes Primarily to facilitate maintenance of our REIT qualification, our charter imposes an ownership limit on our common stock and preferred stock. See "Restrictions on Ownership and Transfer." The attribution provisions of the federal tax laws that are used in applying the ownership limit are complex. They may cause one stockholder to be considered to own the stock of a number of related stockholders. As a result, these provisions may cause a stockholder whose direct ownership of stock does not exceed the ownership limit to, in fact, exceed the ownership limit. The ownership limit could delay or prevent a change in control and, therefore, could adversely affect stockholders' ability to realize a premium over the then-prevailing market price for the common stock in connection with such transaction. The Large Number of Shares Available for Future Sale Could Adversely Affect the Market Price of Our Publicly Traded Securities In connection with the REIT conversion, we have reserved approximately 96.4 million shares of our common stock for future issuance. Up to approximately 48.2 million shares of this common stock may be issued in January 1999. Such common stock will be freely transferable upon receipt. The balance of the reserved common stock may be issued upon the redemption of units of limited partnership interest in Host Marriott, L.P. These limited partnership units will become redeemable at various times over the next year, with approximately 21.7 million limited partnership units becoming redeemable beginning on July 1, 1999, pursuant to each holder's right under Host Marriott, L.P.'s partnership agreement to redeem them for shares of our common stock or, at Host Marriott's election, the cash equivalent thereof. In addition, we have reserved a substantial number of shares of our common stock for issuance pursuant to benefit plans or outstanding options, and such shares of our common stock will be available for sale in the public markets from time to time. Moreover, we may issue additional shares of our common stock in the future. We cannot predict the effect that future sales of shares of our common stock, or the perception that such sales could occur, will have on the market prices of our equity securities. Our FFO and Cash Distributions Will Affect the Market Price of Our Publicly Traded Securities We believe that the market value of a REIT's equity securities is based primarily upon the market's perception of the REIT's growth potential, including its prospects for accretive acquisitions and development, and its current and potential future cash distributions, and is secondarily based upon the real estate market value of the underlying assets. For that reason, our common stock may trade at prices that are higher or lower than the net asset value per share. To the extent we retain operating cash flow for investment purposes, working capital reserves or other purposes, these retained funds, while increasing the value of our underlying assets, may not correspondingly increase the market price of our common stock. Our failure to meet the market's expectations with regard to future FFO and cash distributions would likely adversely affect the market price of our publicly traded securities. 7

Market Interest Rates May Have an Effect on the Value of Our Publicly Traded Securities One of the factors that investors consider important in deciding whether to buy or sell shares of a REIT is the distribution rate on such shares, as a percentage of the price of such shares relative to market interest rates. If market interest rates go up, prospective purchasers of our equity securities may expect a higher dividend yield. Higher interest rates would not, however, result in more funds for us to distribute and, in fact, would likely increase our borrowing costs and potentially decrease cash available for distribution to the extent that our indebtedness has floating interest rates. Thus, higher market interest rates could cause the market price of our publicly traded securities to go down. We are Dependent on External Sources of Capital To qualify as a REIT, we must distribute to our stockholders each year at least 95% of our net taxable income, excluding any net capital gain. Because of these distribution requirements, it is not likely that we will be able to fund all future capital needs, including acquisitions, from income from operations. We therefore will have to rely on third-party sources of capital, which may or may not be available on favorable terms or at all. Our access to third-party sources of capital depends upon a number of factors, including general market conditions, the market's perception of our growth potential, our current and potential future earnings and cash distributions and the market price of our common stock. Moreover, additional equity offerings may result in substantial dilution of stockholders' interests, and additional debt financing may substantially increase our leverage. Our Degree of Leverage Could Limit Our Ability to Obtain Additional Financing Our debt-to-total market capitalization ratio was approximately 55% on a pro forma basis as of December 23, 1998. We have a policy of incurring debt only if, immediately following such incurrence, our debt-to-total market capitalization ratio on a pro forma basis would be 60% or less. Our degree of leverage could affect our ability to obtain financing in the future for working capital, capital expenditures, acquisitions, development or other general corporate purposes and to refinancing borrowings on favorable terms. Our leveraged capital structure also makes us more vulnerable to a downturn in our business or in the economy generally. Moreover, there are no limitations in our organizational documents that limit the amount of indebtedness that we may incur, although our existing debt instruments contain certain restrictions on the amount of indebtedness that we may incur. Accordingly, our Board of Directors could alter or eliminate the 60% policy without stockholder approval to the extent permitted by our debt agreements. If this policy were changed, we could become more highly leveraged, resulting in an increase in debt service payments that could adversely affect our cash flow and consequently our ability to service our debt and make distributions to stockholders. Rental Revenues from Hotels Are Subject to Prior Rights of Lenders The mortgages on certain of our hotels require that rent payments under the leases on such hotels be used first to pay the debt service on such mortgage loans. Consequently, only the cash flow remaining after debt service will be available to satisfy other obligations, including property taxes and insurance, FF&E reserves for the hotels and capital improvements, and debt service on unsecured debt, and to make distributions to stockholders. We Depend on Our Key Personnel We depend on the efforts of our executive officers. While we believe we could find replacements for these key personnel, the loss of their services could have a significant adverse effect on our operations. We do not intend to obtain key-man life insurance with respect to any of our executive officers. The REIT Conversion Could Result in Litigation Over the last several years, business reorganizations involving the combination of several partnerships into a single entity have occasionally given rise to investor lawsuits. These lawsuits have involved claims against 8

the general partners of the participating partnerships, the partnerships themselves and related persons involved in the structuring of, or benefiting from, the conversion or reorganization, as well as claims against the surviving entity and its directors and officers. If any lawsuits are filed in connection with the partnership mergers or other transactions in connection with our REIT conversion, such lawsuits could result in substantial damage claims against us, as successor to the liabilities of our predecessors. Such lawsuits, if successful, could adversely affect our financial condition and our ability to service our debt and make distributions to stockholders. Joint Venture Investments Have Additional Risks Instead of purchasing hotel properties directly, we may invest as a co- venturer. Joint venturers often share control over the operation of the joint venture assets. Actions by a co-venturer could subject such assets to additional risk. Our co-venturer in an investment might have economic or business interests or goals that are inconsistent with our interests or goals, or be in a position to take action contrary to our instructions or requests or contrary to our policies or objectives. Although we generally will seek to maintain sufficient control of any joint venture to permit our objectives to be achieved, we might not be able to take action without the approval of our joint venture partners. Also, our joint venture partners could take actions binding on the joint venture without our consent. A joint venture partner could go bankrupt, leaving us liable for its share of joint venture liabilities. Also, the requirement that we lease our assets to qualify as a REIT may make it more difficult for us to enter into joint ventures in the future. The Year 2000 Problem May Adversely Impact Our Business and Financial Condition Year 2000 issues have arisen because many existing computer programs and chip-based embedded technology systems use only the last two digits to refer to a year, and therefore do not properly recognize a year that begins with "20" instead of the familiar "19." If not corrected, many computer applications could fail or create erroneous results. Our potential year 2000 problems include issues relating to our in-house hardware and software computer systems, as well as issues relating to third parties with which we have a material relationship or whose systems are material to the operations of our hotels. In-House Systems Since October of 1993, we have invested in the implementation and maintenance of accounting and reporting systems and equipment that are intended to enable us to provide adequately for our information and reporting needs and which are also year 2000 compliant. Substantially all of our in-house systems have already been certified as year 2000 compliant through testing and other mechanisms. We have not delayed any systems projects due to the year 2000 issue. We have engaged a third party to review our year 2000 in-house compliance. Third-Party Systems We rely upon operational and accounting systems provided by third parties, primarily the managers of our hotels, to provide the appropriate property-specific operating systems, including reservation, phone, elevator, security, HVAC and other systems, and to provide us with financial information. We will continue to monitor the efforts of these third parties to become year 2000 compliant and will take appropriate steps to address any non-compliance issues. Risks Management believes that future costs associated with year 2000 issues for its in-house systems will be insignificant and therefore not impact our business, financial condition and results of operations. However, the actual effect that year 2000 issues will have on our business will depend significantly on whether other companies and governmental entities properly and timely address year 2000 issues and whether broad-based or systemic failures occur. We cannot predict the severity or duration of any such 9

failures, which could include disruptions in passenger transportation or transportation systems generally, loss of utility and/or telecommunications services, the loss or disruption of hotel reservations made on centralized reservation systems and errors or failures in financial transactions or payment processing systems such as credit cards. Moreover, we are dependent upon Crestline to interface with third parties in addressing year 2000 issues at our hotels leased to its subsidiaries. Due to the general uncertainty inherent with respect to year 2000 issues and our dependence on third parties, including Crestline, we are unable to determine at this time whether the consequences of year 2000 failures will have a material impact on Host Marriott. Although our joint year 2000 compliance program with Crestline is expected to significantly reduce uncertainties arising out of year 2000 issues and the possibility of significant interruptions of normal operations, we cannot assure you that this will be the case. Compliance with the Americans with Disabilities Act Can Be Costly The hotels must comply with Title III of the Americans with Disabilities Act to the extent that such hotels are "public accommodations" or "commercial facilities" as defined by the ADA. The ADA requires removal of structural barriers to access by persons with disabilities in certain public areas of hotels where such removal is readily achievable. We do not believe that substantial non-budgeted capital expenditures will be required in the future to comply with the ADA. Our existing hotel leases would require us to fund any such expenditures. Noncompliance with the ADA could also result in the imposition of fines or an award of damages to private litigants. Unexpected capital expenditures or the payment of fines or damages would decrease our cash available for distribution and potentially adversely affect our ability to make distributions to stockholders. Compliance With Other Regulations Can Also Be Costly Hotels are subject to various forms of regulation in addition to the ADA, including building codes and fire safety regulations. Such regulations may be changed from time to time, or new regulations adopted, resulting in additional or unexpected costs of compliance. Any such increased costs could reduce our cash available for debt service and distributions to stockholders. Environmental Problems are Possible and Can Be Costly We believe that our properties are in compliance in all material respects with applicable environmental laws. Unidentified environmental liabilities could arise, however, and could have a material adverse effect on our financial condition and performance. Federal, state and local laws and regulations relating to the protection of the environment may require a current or previous owner or operator of real estate to investigate and clean up hazardous or toxic substances or petroleum product releases at such property. The owner or operator may have to pay a governmental entity or third parties for property damage and for investigation and clean-up costs incurred by such parties in connection with the contamination. These laws typically impose clean-up responsibility and liability without regard to whether the owner or operator knew of or caused the presence of the contaminants. Even if more than one person may have been responsible for the contamination, each person covered by the environmental laws may be held responsible for all of the clean-up costs incurred. In addition, third parties may sue the owner or operator of a site for damages and costs resulting from environmental contamination emanating from that site. Environmental laws also govern the presence, maintenance and removal of asbestos. These laws require that owners or operators of buildings containing asbestos properly manage and maintain the asbestos, that they notify and train those who may come into contact with asbestos and that they undertake special precautions, including removal or other abatement, if asbestos would be disturbed during renovation or demolition of a building. These laws may impose fines and penalties on building owners or operators who fail to comply with these requirements and may allow third parties to seek recovery from owners or operators for personal injury associated with exposure to asbestos fibers. 10

We Intend to Qualify as a REIT, but We Cannot Guarantee that We Will Qualify We intend to operate to qualify as a REIT for tax purposes beginning in 1999. If we qualify as a REIT, we generally will not be taxed on our income that we distribute to our stockholders so long as we distribute currently at least 95% of our income, excluding our net capital gain. We cannot guarantee, however, that we will qualify as a REIT in 1999 or in any future year. In addition, it is possible that even if we do qualify as a REIT, new tax rules will change the way we are taxed. Hogan & Hartson L.L.P., a law firm, has given us an opinion that we are organized in conformity with the requirements for qualification as a REIT and that beginning January 1, 1999, our proposed method of operation will enable us to satisfy the requirements for qualification and taxation as a REIT. However, Hogan & Hartson based its opinion on a number of assumptions and conditions, including the accuracy of factual representations that we and Host Marriott, L.P. made. These representations relate to a large number of matters, including how we and our subsidiaries operate and will operate in the future and how the hotels are leased. With respect to how the hotels are leased, we made representations to Hogan & Hartson about the economic terms of the leases and the other terms of the leases. We also made representations to Hogan & Hartson about our expectations and the expectations of the lessees regarding the leases. It is important that you understand that Hogan & Hartson's opinion only represents its judgment based on the facts represented by us and does not bind the IRS or the courts. Neither we nor Hogan & Hartson can guarantee that the IRS or a court will agree that we qualify as a REIT. Host Marriott, L.P. May Need to Borrow Money or Issue Additional Equity in Order for Us to Qualify as a REIT A REIT must distribute to its shareholders at least 95% of its net taxable income, excluding any net capital gain. The source of the distributions we make to our stockholders will be money distributed to us by Host Marriott, L.P. We intend to meet this 95% requirement, but there are a number of reasons why Host Marriott, L.P.'s cash flow alone may be insufficient for it to distribute to us the funds we will need. First, as a result of some of the transactions of the Host Predecessors, we expect to recognize large amounts of taxable income in future years for which Host Marriott, L.P. will have no corresponding cash flow or EBITDA. This type of income is often referred to as "phantom income." Second, in order to qualify as a REIT in 1999, we need to distribute to our stockholders, prior to the end of 1999, all of the "earnings and profits" that accumulated prior to 1999. If we do not meet this requirement when the distributions declared in connection with the REIT conversion are paid, we will be required to make further distributions prior to the end of 1999. Host Marriott, L.P. will not have cash flow that corresponds to these distributions and may not be able to borrow or otherwise obtain the funds necessary to distribute to us an amount necessary to make these distributions. Third, the seasonality of the hospitality industry could cause a further mismatch of Host Marriott, L.P.'s income and its cash flow. In addition, even if a REIT meets the 95% requirement, it may still be subject to a 4% nondeductible excise tax. This excise tax applies to the amount by which certain of the REIT's distributions in a given calendar year are less than the sum of 85% of its ordinary income, 95% of its capital gain net income and any undistributed taxable income from prior years. We intend to make distributions so that we will not be subject to this excise tax, but for the reasons described above, Host Marriott, L.P.'s cash flow alone may be insufficient for it to distribute to us the funds we will need. If Host Marriott, L.P.'s cash flow alone is insufficient for it to distribute to us the money we need to meet the 95% distribution requirement or to avoid the 4% excise tax, it will need to issue additional equity or borrow money. We cannot guarantee that these sources of funds will be available to Host Marriott, L.P. on favorable terms or even at all. Any problems Host Marriott, L.P. has in borrowing money could be exacerbated by two factors. First, it will need to distribute most if not all of its earnings to us and so it will be unable to retain these earnings. Accordingly, it generally will need to refinance its maturing debt with additional debt or equity and rely on third-party sources to fund future capital needs. Second, the borrowing needs of Host Marriott, L.P. 11

will be increased if we are required to pay taxes or liabilities attributable to prior years. If Host Marriott, L.P. is unable to raise the money necessary for us to meet the 95% distribution requirement, we will fail to qualify as a REIT. If it is able to raise the money, but only on unfavorable terms, then our financial performance may be hurt. Our Failure to Qualify as a REIT Would Have Serious Adverse Consequences If we fail to qualify as a REIT, we will be subject to federal income tax at regular corporate rates. This additional tax would significantly reduce the cash we would have available to distribute to our stockholders and it could reduce the value of our common stock by a significant amount. Furthermore, if we fail to qualify as a REIT, we will go into default under some of our debt instruments. If we fail to qualify as a REIT, we may be disqualified from treatment as a REIT for the next four taxable years. We Are Required to Distribute All of Our Prior Earnings and Profits, but We Cannot Guarantee that We Will Be Able to Do So In order to qualify as a REIT for 1999, we are required to distribute to our stockholders, prior to the end of 1999, all of our earnings and profits that we accumulated prior to 1999. We believe that we will meet this requirement. However, it is very hard to determine the exact level of our pre-1999 earnings and profits because the determination depends on an extremely large number of factors. The complexity of the determination is compounded by the fact that we started accumulating earnings and profits in 1929. Also, it is difficult to value our distributions which have not been cash, such as the distribution of Crestline common stock we made this past December. Therefore, we cannot guarantee that we will meet this requirement. If we do not meet this requirement, then we will not qualify as a REIT at least for 1999. Hogan & Hartson is not providing us with an opinion regarding the amount of our earnings and profits or whether we meet this requirement. Moreover, for purposes of their opinion that we qualify as a REIT, they relied on our statement that we will meet this requirement. We Will Qualify as a REIT Only if the Rent from the Leases Meets a Number of Tests, but We Cannot Guarantee that It Will A REIT's income must meet certain tests relating to its source. If the income meets the tests, it is called "good income." Almost all of our income will be rent from the hotel leases. This rent will be good income only if the leases are respected as true leases for federal income tax purposes. If the leases are treated as service contracts, joint ventures or some other type of arrangement, then this rent will not be good income and we will fail to qualify as a REIT. See "Federal Income Tax Considerations--Federal Income Taxation of Host Marriott--Income Tests Applicable to REITs." In addition, the rent from any particular hotel lease will be good income only if we own less than 10% of the lessee of the hotel. For purposes of this test, we are treated as owning both any interests that we hold directly and the interests owned by a person who owns more than 10% of our stock. In determining who owns more than 10% of our stock, a person may be treated as owning the stock of another person who is either a relative or has common financial interests. We will not directly own more than 10% of any of the lessees. In addition, we intend to enforce the ownership limit in our charter, which restricts the amount of our capital stock that any person can own. If the ownership limit is effective, then no person will ever own more than 10% of our capital stock and we should never own more than 10% of the lessees. However, we cannot guarantee that the ownership limit will be effective. If the ownership limit is not effective, our ownership in the lessees may exceed the 10% limit. As a result, the rent from our leases would not be good income and we would fail to qualify as a REIT. Furthermore, rent from any particular hotel lease will be good income only if no portion of the rent is based on the income or profits of the lessee of the hotel. The rent, however, can be based on the gross revenues of the lessees, unless the arrangement does not conform to normal business practice or is being used as a 12

device to base rent on the income or profits of the lessees. The rent from the current leases, other than the Harbor Beach Resort lease, is based on the gross revenues of the lessees. We believe that the leases conform to normal business practice and, other than the Harbor Beach Resort lease, are not being used as a device to base rent on the income or profits of the lessees. Hogan & Hartson has not given us an opinion on this issue, and we cannot guarantee that the IRS will agree with our position. If rent from leases in addition to the Harbor Beach Resort lease is found to be based on the income or profits of the lessees, the rent would not be good income and we would fail to qualify as a REIT. We Will Qualify as a REIT Only If the Personal Property Arrangements Are Respected Rent that is attributable to personal property is not good income under the REIT rules. Hotels contain significant personal property. Therefore, in order to protect our ability to qualify as a REIT, Host Marriott, L.P. is selling an estimated $75 million of personal property associated with some of our hotels to the non-controlled subsidiaries. The non-controlled subsidiaries lease the personal property associated with each hotel directly to the lessee that is leasing the hotel. Under each personal property lease, the non-controlled subsidiary receives rent payments directly from the applicable lessee. We believe the amount of the rent represents the fair rental value of the personal property. If for any reason these lease arrangements are not respected for federal income tax purposes, we likely would not qualify as a REIT. We Will Be Subject to Taxes Even if We Qualify as a REIT Even if we qualify as a REIT, we will be subject to some federal, state and local taxes on our income and property. For example, we will have to pay tax on income that we do not distribute. We also will be liable for any tax that the IRS successfully asserts against Host Marriott's predecessors for corporate income taxes for years prior to 1999. Furthermore, we will derive income from the non-controlled subsidiaries and they will be subject to regular corporate taxes. In addition, we and our subsidiaries contributed a large number of assets to Host Marriott, L.P. with a value that was substantially greater than our tax basis in the assets. We refer to these assets as assets with "built-in gain." We will be subject to tax on the built-in gain if Host Marriott, L.P. sells these assets prior to the end of 2008. We also have substantial deferred tax liabilities that we or a non-controlled subsidiary will recognize, without the receipt by us of any corresponding cash. Even if Host Marriott, L.P. does not sell the built-in gain assets prior to the end of 2008, there are a number of other transactions that likely would cause us to be subject to the tax on the built-in gain. For example, we are likely to recognize gain if Host Marriott, L.P. sells a hotel contributed to it after 2008, refinances a loan secured by a hotel contributed to it, spends money to improve a hotel contributed to it, or issues additional limited partnership units. Lastly, over time, Host Marriott, L.P. will allocate income and depreciation to its partners in such a way that it will eliminate the built-in gain in its assets. As a result of these various events, it is likely that over the next several years, we will recognize a large amount of the built-in gain associated with the assets that we contributed to Host Marriott, L.P. In connection with this gain, neither we nor Host Marriott, L.P. will receive any corresponding cash. If the Operating Partnership Is Treated as a Corporation, We Will Fail to Qualify as a REIT A REIT cannot own more than 10% of the voting securities of a corporation. We own more than 10% of the voting securities of Host Marriott, L.P. Accordingly, if Host Marriott, L.P. is treated as a corporation, we will fail to qualify as a REIT. See "Federal Income Tax Consideration--Tax Aspects of Host Marriott's Ownership of Interests in Host Marriott, L.P.--Entity Classification. We also should point out that if Host Marriott, L.P. is treated as a corporation, it will be subject to corporate income tax. This would significantly reduce the amount of cash it would have available to distribute to us, which would in turn reduce the amount of cash we would have available to distribute to our stockholders. 13

THE COMPANY Host Marriott was formed to continue and expand the hotel lodging property ownership business of its predecessors. Host Marriott succeeded to this business as a result of its merger with Host Marriott Corporation, a Delaware corporation, and other restructuring transactions consummated in December 1998 which we refer to as the "REIT conversion." Host Marriott is one of the largest owners of hotels in the world, with ownership of or controlling interests in approximately 126 upscale and luxury full-service hotel lodging properties in its portfolio as of December 30, 1998. Virtually all of these properties are leased to subsidiaries of Crestline, formerly a wholly owned subsidiary of Host Marriott, and are generally operated under the Marriott and Ritz-Carlton brand names and managed by Marriott International. Host Marriott intends to make an election to be taxed as a REIT for federal income tax purposes effective for its taxable year beginning January 1, 1999. Host Marriott owns all of its assets and conducts substantially all of its business through Host Marriott, L.P. and its subsidiaries. Host Marriott is the sole general partner of Host Marriott, L.P. Host Marriott's principal executive offices are located at 10400 Fernwood Road, Bethesda, Maryland 20817-1109, and its telephone number is (301) 380- 9000. 16

USE OF PROCEEDS Unless otherwise indicated in the applicable prospectus supplement, we anticipate that any net proceeds from the sale of offered securities will be used for general operational purposes, which may include, but are not limited to, working capital, capital expenditures, acquisitions and the repayment or repurchase of the indebtedness of Host Marriott or our subsidiaries or our capital stock. The factors which we will consider in any repayment or repurchase of its indebtedness will include the amount and characteristics of any offered securities issued and may include, among others, the impact of such refinancing on the liquidity of Host Marriott or on our debt-to-capital ratio and funds from operations ("FFO") per share. When a particular series of offered securities is offered, the prospectus supplement relating thereto will set forth the intended use for the net proceeds received from the sale of such offered securities. Pending the application of the net proceeds, we expect to invest such proceeds in short-term, interest-bearing instruments or other investment-grade debt securities or to reduce indebtedness under our bank credit agreement. ERISA MATTERS Host Marriott and our subsidiaries may each be considered a "party in interest," within the meaning of the Employee Retirement Income Security Act, or a "disqualified person," within the meaning of Section 4975 of the Internal Revenue Code, with respect to many employee benefit plans that are subject to ERISA. The purchase of offered securities by an ERISA plan, including an individual retirement plan, that is subject to the fiduciary responsibility provisions of ERISA or the prohibited transaction provisions of the Internal Revenue Code and with respect to which Host Marriott or any of our affiliates is a service provider, or otherwise is a party in interest or a disqualified person, may constitute or result in a prohibited transaction under ERISA or the Internal Revenue Code, unless such offered securities are acquired pursuant to and in accordance with an applicable federal statutory exemption, or administrative exemption issued on a class-wide basis by the United States Department of Labor. Any pension or other employee benefit plan proposing to acquire any offered securities should consult with its counsel. 17

RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS The following table sets forth Host Marriott's ratio of earnings to combined fixed charges and preferred stock dividends on a historical basis for the periods indicated. 3rd Quarter Fiscal Year ----------- -------------------------------------- 1998 1997 1997 1996 1995 1994 1993 ----- ----- ------- ------- ------ ------ ------ (in millions, except ratio data) Ratio of earnings to combined fixed charges and preferred stock dividends(a)........... 1.7x 1.4x 1.3x 1.0x -- -- -- Deficiency of earnings to com- bined fixed charges and pre- ferred stock dividends(b).... -- -- -- -- $ 70 $ 12 $ 45 - -------- (a) The ratio of earnings to fixed charges and preferred stock dividends is computed by dividing income from continuing operations before income taxes and fixed charges and preferred stock dividends by total fixed charges and preferred stock dividends. Fixed charges represent interest expense (including capitalized interest), the amortization of debt issuance costs, and the portion of rental expense that represents interest. (b) The deficiency of earnings to fixed charges and preferred stock dividends in 1995, 1994 and 1993 is largely the result of depreciation and amortization of $122 million in 1995, $113 million in 1994 and $196 million in 1993. In addition, the deficiency for 1995 was impacted by the $60 million pre-tax charge to write-down the carrying value of one undeveloped land parcel to its estimated sales value.

DESCRIPTION OF COMMON STOCK The following description sets forth the general terms of the common stock which Host Marriott may issue. The description set forth below and in any prospectus supplement does not purport to be complete and is subject to and qualified in its entirety by reference to Host Marriott's Articles of Amendment and Restatement of Articles of Incorporation and Bylaws, each of which will be made available upon request. General Our Articles of Incorporation provide that the total number of shares of stock of all classes which Host Marriott has authority to issue is 800,000,000 shares of stock, initially consisting of 750,000,000 shares of common stock and 50,000,000 shares of preferred stock. The Board of Directors is authorized, without a vote of stockholders, to classify or reclassify any unissued shares of capital stock and to establish the preferences and rights of any preferred or other class or series of capital stock to be issued. At December 28, 1998, 205,262,058 shares of our common stock were issued and outstanding. Subject to the preferential rights of any other classes or series of shares of capital stock and to the provisions of the Articles of Incorporation regarding restrictions on transfers of shares of capital stock, holders of our common stock are entitled to receive distributions if, as and when authorized and declared by the Board of Directors, out of assets legally available therefor and to share ratably in the assets of Host Marriott legally available for distribution to its stockholders in the event of its liquidation, dissolution or winding-up after payment of, or adequate provision for, all known debts and liabilities of Host Marriott. Host Marriott currently intends to pay regular quarterly distributions. Subject to the provisions of the Articles of Incorporation regarding restrictions on the transfer of shares of capital stock, each outstanding share of common stock entitles the holder to one vote on all matters submitted to a vote of stockholders, including the election of directors, and, except as provided with respect to any other class or series of shares of Host Marriott's capital stock, the holders of shares of common stock will possess the exclusive voting power. There is no cumulative voting in the election of directors, which means that the holders of a majority of the outstanding common stock can elect all of the directors then standing for election. Holders of shares of common stock have no preferences, conversion, sinking fund, redemption rights or preemptive rights to subscribe for any securities of Host Marriott. Subject to the provisions of the Articles of Incorporation regarding restrictions on transfer of capital stock, shares of common stock have equal distribution, liquidation and other rights. Under Maryland corporate law, a Maryland corporation generally cannot dissolve, amend its charter, merge, consolidate, effect a share exchange or transfer its assets unless approved by the Board of Directors and by stockholders holding at least two-thirds of the shares entitled to vote on the matter unless a greater or lesser percentage, but not less than a majority, is set forth in the corporation's charter. Under our Articles of Incorporation, any merger, consolidation, share exchange or transfer of assets must be approved by the Board of Directors and by stockholders. The Articles of Incorporation generally provide for stockholder approval of such transactions by a two-thirds vote of all the votes entitled to be cast, except that any merger of Host Marriott with or into a trust organized for the purpose of changing Host Marriott's form of organization from a corporation to a trust will require the approval of stockholders of Host Marriott by the affirmative vote only of a majority of all the votes entitled to be cast on the matter. In addition, under the MGCL, certain mergers may be accomplished without a vote of stockholders. For example, no stockholder vote is required for a merger of a subsidiary of a Maryland corporation into its parent, provided the parent owns at least 90% of the subsidiary. In addition, a merger need not be approved by stockholders of a Maryland successor corporation if the merger does not reclassify or change the outstanding shares or otherwise amend the charter, and the number of shares to be issued or delivered in the merger is not more than 20% of the number of its shares of the same class or series outstanding immediately before the merger becomes effective. A share exchange need be approved by a Maryland successor only by its Board of Directors. Any amendments to the provisions contained in the Articles 19

of Incorporation relating to restrictions on transferability of stock, the classified Board and fixing the size of the Board within the range set forth in the Articles of Incorporation, as well as the provisions relating to removal of directors, the filling of Board vacancies and the exclusive authority of the Board of Directors to amend the Bylaws will require the approval of the Board of Directors and stockholders by the affirmative vote of the holders of not less than two-thirds of the votes entitled to be cast on the matter. Other amendments to the Articles of Incorporation may be effected by requisite action of the Board of Directors and approval by stockholders by the affirmative vote of not less than a majority of the votes entitled to be cast on the matter. The Articles of Incorporation authorize the Board of Directors to reclassify any unissued shares of common stock into other classes or series of capital stock, including preferred stock, and to establish the number of shares in each class or series and to set the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications or terms or conditions of redemption for each such class or series. Transfer Agent and Registrar The transfer agent and registrar for the common stock will be First Chicago Trust Company of New York. Stockholder Rights Plan/Preferred Stock Purchase Rights The Board of Directors has adopted a stockholder rights plan pursuant to a Rights Agreement dated as of November 23, 1998 between Host Marriott and The Bank of New York, as rights agent. Each share of common stock issued by Host Marriott between the date of adoption of the Rights Agreement and the Rights Distribution Date or the date, if any, on which the Rights are redeemed, would have one preferred stock purchase right (a "Right") attached to it. The Rights will expire on November 22, 2008, unless earlier redeemed or exchanged. Each Right, when exercisable, would entitle the holder to purchase one unit of Host Marriott Series A Junior Participating Preferred Stock, equal to one one- thousandth of a share of such stock, at a purchase price equal to $55.00 per unit, subject to adjustment. Until a Right is exercised, the holder thereof, as such, would have no rights as a stockholder of Host Marriott, including, without limitation, the right to vote or to receive dividends. The Rights Agreement provides that the Rights initially attach to all certificates representing common stock then outstanding. The Rights would separate from the common stock and a distribution of Rights certificates would occur (a "Rights Distribution Date") upon the earlier to occur of . ten days following a public announcement that a person or group of affiliated or associated persons (an "Acquiring Person") has acquired, or obtained the right to acquire, beneficial ownership of 20% or more of the outstanding common stock (the "Stock Acquisition Date") or . ten business days, or such later date as the Board of Directors may determine, following the commencement of a tender offer or exchange offer, the consummation of which would result in the beneficial ownership by a person of 20% or more of the outstanding common stock. For the purposes of determining the 20% threshold amount, the following shares of Host Marriott common stock are not included: . shares received pursuant to the Agreement and Plan of Merger, dated November 23, 1998, pursuant to which Host Marriott Corporation, a Delaware corporation, was merged into Host Marriott, in exchange for shares of common stock of Host Marriott Corporation, which such person beneficially owned on February 3, 1989 and owned continuously thereafter; . shares acquired by a person pursuant to a gift, bequest, inheritance or distribution from a trust or from a corporation controlled by such person where such shares of common stock were exempt shares under the Rights Agreement immediately prior to such acquisition and where such shares of common stock were beneficially owned by such person continuously after such acquisition; . shares acquired as a result of a stock dividend, stock distribution or other recapitalization with respect to exempt shares under the Rights Agreement; and 20

. shares that can be acquired by Marriott International pursuant to the Marriott International purchase right. Until the Rights Distribution Date, the Rights will be evidenced by the common stock certificates, and will be transferred with, and only with, the common stock certificates. The Rights are not exercisable until the Rights Distribution Date. If a person becomes the beneficial owner of 20% or more of the then outstanding common stock, except pursuant to an offer for all outstanding common stock which the directors by a two-thirds vote determine to be fair to and otherwise in the best interests of Host Marriott and its stockholders, each holder of a Right would, after the end of a redemption period, have the right to exercise the Right by purchasing, for an amount equal to the purchase price, shares of common stock having a value equal to two times the purchase price, subject to the ownership limit. All Rights acquired by the Acquiring Person will be null and void. Each holder of a Right would have the right to receive, upon exercise, common shares of the acquiring company having a value equal to two times the purchase price of the Right if, at any time following the Stock Acquisition Date, . Host Marriott is acquired in a merger or other business combination transaction in which it is not the surviving corporation, other than a merger which follows an offer described in the preceding paragraph, or . 50% or more of Host Marriott's assets or earning power is sold or transferred. At any time after a person becomes an Acquiring Person, the Board of Directors may exchange the Rights at an exchange ratio of one share of Host Marriott common stock per Right. In general, the Board of Directors may redeem the Rights at a price of $.005 per Right at any time until ten days after an Acquiring Person has been identified as such. If the decision to redeem the Rights occurs after a person becomes an Acquiring Person, the decision will require a two-thirds vote of directors. The Rights have certain anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire Host Marriott. The Rights, however, would not interfere with any merger or other business combination approved by the Board of Directors since the Board may, at its option, at any time prior to any person becoming an Acquiring Person, redeem all rights or amend the Rights Agreement to exempt the person from the Rights Agreement. DESCRIPTION OF PREFERRED STOCK The following description sets forth the general terms of the preferred stock which Host Marriott may issue. The description set forth below and in any prospectus supplement does not purport to be complete and is subject to and qualified in its entirety by reference to the Articles of Incorporation, the applicable Articles Supplementary to the Articles of Incorporation determining the terms of the related series of preferred stock and the Bylaws, each of which will be made available upon request. General The Articles of Incorporation authorize the Board of Directors to issue 50 million shares of preferred stock and to classify or reclassify any unissued preferred shares into one or more classes or series of capital stock, including common stock. Prior to issuance of shares of any class or series of stock other than common stock, the Board of Directors is required, under the MGCL, to set, subject to the provisions of the Articles of Incorporation regarding the restriction on transfer of capital stock, the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or 21

conditions of redemption for each such class or series. Thus, the Board of Directors could authorize the issuance of preferred stock or other capital stock with terms and conditions which could have the effect of delaying, deferring or preventing a transaction or a change in control of Host Marriott that might involve a premium price for holders of shares of common stock or otherwise be in their best interest. As of the date hereof, only common stock is outstanding, but the Company may issue preferred stock or other capital stock in the future. Reference is made to the prospectus supplement relating to the class or series of preferred stock being offered for the specific terms thereof, including: (a) The title and stated value of such preferred stock; (b) The number of shares of such preferred stock offered, the liquidation preference per share and the purchase price of such preferred stock; (c) The dividend rate(s), period(s) and/or payment date(s) or method(s) of calculation thereof applicable to such preferred stock; (d) Whether dividends shall be cumulative or non-cumulative and, if cumulative, the date from which dividends on such preferred stock shall accumulate; (e) The procedures for any auction and remarketing, if any, for such preferred stock; (f) The provisions for a sinking fund, if any, for such preferred stock; (g) The provisions for redemption, if applicable, of such preferred stock; (h) Any listing of such preferred stock on any securities exchange or market; (i) The terms and conditions, if applicable, upon which such preferred stock will be convertible into common stock of Host Marriott, including the conversion price or manner of calculation thereof and conversion period; (j) The terms and conditions, if applicable, upon which preferred stock will be exchangeable into debt securities, including the exchange price or manner of calculation thereof and exchange period; (k) Voting rights, if any, of such preferred stock; (l) Whether interests in such preferred stock will be represented by depositary shares; (m) A discussion of any material and/or special United States federal income tax considerations applicable to such preferred stock; (n) The relative ranking and preferences of such preferred stock as to dividend rights and rights upon liquidation, dissolution or winding up of the affairs of Host Marriott; (o) Any limitations on issuance of any class or series of preferred stock ranking senior to or on a parity with such series of preferred stock as to dividend rights and rights upon liquidation, dissolution or winding up of the affairs of Host Marriott; and (p) Any other specific terms, preferences, rights, limitations or restrictions of such preferred stock. Rank Unless otherwise specified in the applicable prospectus supplement, the preferred stock will, with respect to distribution rights and rights upon liquidation, dissolution or winding up of Host Marriott, rank (i) senior to all classes or series of common stock of Host Marriott and to all equity securities the terms of which specifically provide that such equity securities rank junior to such preferred stock; (ii) on a parity with all equity securities issued by Host Marriott other than referred to in clauses (i) and (iii); and (iii) junior to all equity securities issued by Host Marriott the terms of which specifically provide that such equity securities rank senior to such preferred stock. The term "equity securities" does not include convertible debt securities. 22

Distributions Holders of the preferred stock of each series will be entitled to receive, when, as and if declared by the Board of Directors, out of assets of Host Marriott legally available for payment to stockholders, cash distributions, or distributions in kind or in other property if expressly permitted and described in the applicable prospectus supplement, at such rates and on such dates as will be set forth in the applicable prospectus supplement. Each such distribution shall be payable to holders of record as they appear on the stock transfer books of Host Marriott on such record dates as shall be fixed by the Board of Directors. Distributions on any series of preferred stock, if cumulative, will be cumulative from and after the date set forth in the applicable prospectus supplement. If the Board of Directors fails to declare a distribution payable on a distribution payment date on any series of the preferred stock for which distributions are non-cumulative, then the holders of such series of preferred stock will have no right to receive a distribution in respect of the distribution period ending on such distribution payment date, and Host Marriott will have no obligation to pay the distribution accumulated for such period, whether or not distributions on such series are declared payable on any future distribution payment date. Unless otherwise specified in the applicable prospectus supplement, if any shares of preferred stock of any series are outstanding, no full distributions shall be declared or paid or set apart for payment on any shares of capital stock of Host Marriott of any other series ranking, as to distributions, on a parity with or junior to the shares of preferred stock of such series for any period unless full distributions, including any cumulative amount if applicable, have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for such payment on the preferred stock of such series. When distributions are not paid in full, or a sum sufficient for such full payment is not so set apart, upon preferred stock of any series and the shares of any other series of preferred stock ranking on a parity as to distributions with the shares of preferred stock of such series, all distributions declared upon preferred stock of such series and any other series of preferred stock ranking on a parity as to distributions with such shares of preferred stock shall be declared pro rata so that the amount of distributions declared per share of preferred stock of such series and such other series of preferred stock shall in all cases bear to each other the same ratio that accumulated distributions per share on the preferred stock of such series and such other series of preferred stock, which shall not include any accumulation in respect of unpaid distributions for prior distribution periods if such shares of preferred stock do not have a cumulative distribution, bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on shares of preferred stock of such series which may be in arrears. Except as provided in the immediately preceding paragraph, unless full distributions, including any cumulative amount if applicable, on the shares of preferred stock have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for payment for the then current distribution period, then . no distributions, other than in common stock or other shares of capital stock ranking junior to the shares of preferred stock of such series as to distributions and upon liquidation, shall be declared or paid or set aside for payment or other distribution upon the common stock, or any other shares of capital stock of Host Marriott ranking junior to or on a parity with the shares of preferred stock of such series as to distributions or upon liquidation, and . no common stock, or any other shares of capital stock of Host Marriott ranking junior to or on a parity with the shares of preferred stock of such series as to distributions or upon liquidation shall be redeemed, purchased or otherwise acquired for any consideration or any money paid to or made available for a sinking fund for the redemption of any such shares, by Host Marriott, except by conversion into or exchange for other shares of capital stock of Host Marriott ranking junior to the shares of preferred stock of such series as to distributions and upon liquidation. If, for any taxable year, Host Marriott elects to designate as "capital gain dividends" any portion (the "Capital Gains Amount") of the dividends paid or made available for the year to holders of all classes of 23

capital stock (the "Total Dividends"), then the portion of the Capital Gains Amount that will be allocable to the holders of preferred stock will be the Capital Gains Amount multiplied by a fraction, the numerator of which will be the total dividends paid or made available to the holders of the preferred stock for the year and the denominator of which shall be the Total Dividends. Redemption If so provided in the applicable prospectus supplement, the preferred stock will be subject to mandatory redemption or redemption at the option of Host Marriott, in whole or in part, in each case upon the terms, at the times and at the redemption prices set forth in such prospectus supplement. The prospectus supplement relating to a series of preferred stock that is subject to mandatory redemption will specify the number of such shares of preferred stock that shall be redeemed by Host Marriott on the date(s) or during the period(s) to be specified, at a redemption price per share to be specified therein. Notwithstanding the foregoing, the holders of record of preferred stock at the close of business on a dividend record date will be entitled to receive the dividend payable on such preferred stock on the corresponding dividend payment date notwithstanding the redemption of such preferred stock after such record date and on or prior to such payment date, in which case the redemption price shall not include such dividend. The redemption price may be payable in cash or other property, as specified in the applicable prospectus supplement. If the redemption price for preferred stock of any series is payable only from the net proceeds of the issuance of shares of capital stock of Host Marriott, the terms of such preferred stock may provide that, if no such shares of capital stock shall have been issued or to the extent the net proceeds from any issuance are insufficient to pay in full the aggregate redemption price then due, such preferred stock shall automatically and mandatorily be converted into the applicable shares of capital stock of Host Marriott pursuant to conversion provisions specified in the applicable prospectus supplement. Notwithstanding the foregoing, unless full distributions, including any cumulative amount if applicable, on the shares of preferred stock of such series have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for payment for the then current distribution period, then . no preferred stock of any series shall be redeemed unless all outstanding shares of preferred stock of such series are simultaneously redeemed provided, however, that the foregoing shall not prevent the redemption, purchase or acquisition of shares of preferred stock of such series to preserve the REIT status of Host Marriott or pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding preferred stock of such series, and . Host Marriott shall not purchase or otherwise acquire directly or indirectly any shares of preferred stock of such series, except by conversion into or exchange for shares of capital stock of Host Marriott ranking junior to the preferred stock of such series as to distributions and upon liquidation; provided, however, that the foregoing shall not prevent the redemption, purchase or acquisition of shares of preferred stock of such series to assist in maintaining the REIT status of Host Marriott or pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding shares of preferred stock of such series. If fewer than all of the outstanding shares of preferred stock of any series are to be redeemed, the number of shares to be redeemed will be determined by Host Marriott and such shares may be redeemed pro rata from the holders of record of such shares in proportion to the number of such shares held or for which redemption is requested by such holder or by lot in a manner determined by Host Marriott. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of record of preferred stock of any series to be redeemed at the address shown on the stock transfer books of Host Marriott. Each notice shall state: (a) the redemption date; (b) the number and series of shares of preferred stock to be redeemed; 24

(c) the place or places where certificates for such preferred stock are to be surrendered for payment of the redemption price; (d) that distributions on the shares to be redeemed will cease to accrue on such redemption date; and (e) the date upon which the holders' conversion rights, if any, as to such shares shall terminate. If fewer than all of the shares of preferred stock of any series are to be redeemed, the notice mailed to each such holder thereof shall also specify the number of shares of preferred stock to be redeemed from each such holder. If notice of redemption of any preferred stock has been given and if the funds necessary for such redemption have been set aside by Host Marriott in trust for the benefit of the holders of any preferred stock so called for redemption, then from and after the redemption date distributions will cease to accumulate on such preferred stock, and all rights of the holders of such shares will terminate, except the right to receive the redemption price. Liquidation Preference Upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of Host Marriott, then, before any distribution or payment shall be made to the holders of any common stock or any other class or series of shares of capital stock of Host Marriott ranking junior to the preferred stock in the distribution of assets upon any liquidation, dissolution or winding up of Host Marriott, the holders of each series of preferred stock shall be entitled to receive out of assets of Host Marriott legally available for distribution to shareholders liquidating distributions in the amount of the liquidation preference set forth in the applicable prospectus supplement, plus an amount equal to all accumulated and unpaid distributions. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of shares of preferred stock will have no right or claim to any of the remaining assets of Host Marriott. If, upon any such voluntary or involuntary liquidation, dissolution or winding up, the available assets of Host Marriott are insufficient to pay the amount of the liquidating distributions on all outstanding shares of preferred stock and the corresponding amounts payable on all shares of other classes or series of shares of capital stock of Host Marriott ranking on a parity with the preferred stock in the distribution of assets, then the holders of the preferred stock and all other such classes or series of shares of capital stock shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled. If liquidating distributions shall have been made in full to all holders of preferred stock, the remaining assets of Host Marriott shall be distributed among the holders of any other classes or series of shares of capital stock ranking junior to the preferred stock upon liquidation, dissolution or winding up, according to their respective rights and preferences and in each case according to their respective number of shares. For such purposes, the consolidation or merger of Host Marriott with or into any other corporation, trust or entity, or the sale, lease or conveyance of all or substantially all of the property or business of Host Marriott, shall not be deemed to constitute a liquidation, dissolution or winding up of Host Marriott. Voting Rights Holders of preferred stock will not have any voting rights, except as set forth below or as otherwise from time to time required by law or as indicated in the applicable prospectus supplement. Whenever distributions on any shares of preferred stock shall be in arrears for six or more quarterly periods, whether or not consecutive: . the holders of such preferred stock, voting together as a single class with all other series of preferred stock upon which like voting rights have been conferred and are exercisable, will be entitled to vote for the election of two additional Directors of Host Marriott at a special meeting called by the holders of record of at least 10% of any series of preferred stock so in arrears, unless such request is received less than 90 days before the date fixed for the next annual or special meeting of the stockholders, or at the next annual meeting of stockholders, and at each subsequent annual meeting and 25

. such voting rights will continue until all distributions accumulated on a series of cumulative preferred stock for the past distribution periods and the then current distribution period shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment or four consecutive quarterly distributions on a non-cumulative preferred series shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment. Unless provided otherwise for any series of preferred stock, so long as any shares of preferred stock remain outstanding, Host Marriott will not, without the affirmative vote or consent of the holders of at least two-thirds of each series of preferred stock outstanding at the time, given in person or by proxy, either in writing or at a meeting, . authorize or create, or increase the authorized or issued amount of, any class or series of shares of capital stock ranking senior to such series of preferred stock with respect to the payment of distributions or the distribution of assets upon liquidation, dissolution or winding up or reclassify any authorized shares of capital stock of Host Marriott into such shares, or create, authorize or issue any obligation or security convertible into or evidencing the right to purchase any such shares; or . amend, alter or repeal the provisions of Host Marriott's charter or the Articles Supplementary for such series of preferred stock, whether by merger, consolidation or otherwise (an "Event"), so as to materially and adversely affect any right, preference, privilege or voting power of such series of preferred stock or the holders thereof; provided, however, with respect to the occurrence of any Event, so long as the shares of preferred stock remain outstanding or are converted into like securities of the surviving entity, in each case with the terms thereof materially unchanged, taking into account that upon the occurrence of an Event, Host Marriott may not be the surviving entity and that the surviving entity may be a non-corporate entity, such as a limited liability company, limited partnership or business trust in which case the preferred stock would be converted into an equity interest, other than stock, having substantially equivalent terms, the occurrence of any such Event shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers of holders of preferred stock; and provided further that any increase in the amount of the authorized preferred stock or any increase in the amount of authorized shares of such series or any other series of preferred stock, in each case ranking on a parity with or junior to the preferred stock of such series with respect to payment of distributions and the distribution of assets upon liquidation, dissolution or winding up of Host Marriott, shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers. The foregoing voting provisions will not apply if, at or prior to the time when the act with respect to which such vote would otherwise be required shall be effected, all outstanding shares of preferred stock of such series shall have been converted or redeemed or called for redemption and sufficient funds shall have been deposited in trust to effect such redemption. Conversion Rights The terms and conditions, if any, upon which any series of preferred stock is convertible into common stock will be set forth in the applicable prospectus supplement relating thereto. Such terms will include the number of shares of common stock into which the shares of preferred stock are convertible, the conversion price or the manner of calculating the conversion price, the conversion date(s) or period(s), provisions as to whether conversion will be at the option of the holders of the preferred stock or Host Marriott, the events requiring an adjustment of the conversion price and provisions affecting conversion in the event of the redemption of such series of preferred stock. Transfer Agent and Registrar The transfer agent and registrar for the preferred stock will be set forth in the applicable prospectus supplement. 26

RESTRICTIONS ON OWNERSHIP AND TRANSFER For Host Marriott to qualify as a REIT under the Internal Revenue Code, no more than 50% in value of its outstanding shares of stock may be owned, actually or constructively, by five or fewer individuals, as defined in the Internal Revenue Code to include certain entities . during the last half of a taxable year other than the first year for which an election to be treated as a REIT has been made or . during a proportionate part of a shorter taxable year. In addition, if Host Marriott, or one or more owners of 10% or more of Host Marriott, actually or constructively owns 10% or more of a tenant of Host Marriott or a tenant of any partnership in which Host Marriott is a partner, the rent received by Host Marriott either directly or through any such partnership from such tenant will not be qualifying income for purposes of the REIT gross income tests of the Internal Revenue Code. A REIT's shares also must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of twelve months or during a proportionate part of a shorter taxable year other than the first year for which an election to be treated as a REIT has been made. Primarily because the Board of Directors believes it is desirable for Host Marriott to qualify as a REIT, the Articles of Incorporation provide that, subject to certain exceptions, no person or persons acting as a group may own, or be deemed to own by virtue of the attribution provisions of the Internal Revenue Code, more than . 9.8% of the lesser of the number or value of shares of common stock outstanding or . 9.8% of the lesser of the number or value of the issued and outstanding preferred or other shares of any class or series of Host Marriott's stock. The foregoing are subject to . an exception for a holder of shares of common stock solely by reason of the Merger in excess of the ownership limit so long as such holder would not own, directly or by attribution under the Internal Revenue Code, more than 9.9% by value of the outstanding capital stock of Host Marriott as of December 30, 1998, and . a limitation on the application of the "group" limitation, but no other element of the ownership limit, to any "group" that otherwise would exceed the ownership limit at the effective time of the Merger solely by reason of its status as a "group." The ownership limit prohibits Marriott International and its subsidiaries and affiliates, including members of the Marriott family, from collectively owning shares of capital stock in excess of the ownership limit, but the Board of Directors will grant an exception that will permit Marriott International to exercise its right to purchase up to 20% of each class of Host Marriott's voting stock in connection with a change in control of Host Marriott, but only in the event that . Marriott International and its subsidiaries and affiliates, including members of the Marriott family, do not own at such time or thereafter, directly and by attribution, 10% or more of Crestline or any of the lessees and . such ownership of Host Marriott's shares would not cause Host Marriot, L.P. to be considered to own, directly or by attribution, 10% or more of Crestline or any of the lessees. The ownership attribution rules under the Internal Revenue Code are complex and may cause capital stock owned actually or constructively by a group of related individuals and/or entities to be owned constructively by one individual or entity. As a result, the acquisition of less than 9.8% of the common stock or the acquisition or ownership of an interest in an entity that owns, actually or constructively, common stock, by an individual or entity could nevertheless cause that individual or entity, or another individual or entity, to own constructively in excess of 9.8% of the outstanding common stock and thus subject such common stock to the remedy provision 27

under the ownership limit. The Board of Directors may grant an exemption from the ownership limit with respect to one or more persons who would not be treated as "individuals" for purposes of the Internal Revenue Code if it is satisfied, based upon an opinion of counsel and such other evidence as is satisfactory to the Board of Directors in its sole discretion, that . such ownership will not cause a person who is an individual to be treated as owning capital stock in excess of the ownership limit, applying the applicable constructive ownership rules, and . will not otherwise jeopardize Host Marriott's status as a REIT by, for example, causing any tenant of Host Marriott, L.P., including Crestline and the lessees, to be considered a "related party tenant" for purposes of the REIT qualification rules. As a condition of such waiver, the Board of Directors may require undertakings or representations from the applicant with respect to preserving the REIT status of Host Marriott. The Board of Directors will have the authority to increase the ownership limit from time to time, but will not have the authority to do so to the extent that after giving effect to such increase, five beneficial owners of capital stock could beneficially own in the aggregate more than 49.5% of the outstanding capital stock. The Articles of Incorporation further prohibit . any person from actually or constructively owning shares of beneficial interest of Host Marriott that would result in Host Marriott being "closely held" under Section 856(h) of the Internal Revenue Code or otherwise cause Host Marriott to fail to qualify as a REIT and . any person from transferring shares of Host Marriott's capital stock if such transfer would result in shares of Host Marriott's capital stock being owned by fewer than 100 persons. Any person who acquires or attempts or intends to acquire actual or constructive ownership of shares of Host Marriott's capital stock that will or may violate any of the foregoing restrictions on transferability and ownership is required to give notice immediately to Host Marriott and provide Host Marriott with such other information as Host Marriott may request in order to determine the effect of such transfer on Host Marriott's status as a REIT. If any purported transfer of shares of Host Marriott's capital stock or any other event would otherwise result in any person violating the ownership limit or the other restrictions in the Articles of Incorporation, then any such purported transfer will be void and of no force or effect with respect to the purported transferee (the "Prohibited Transferee") as to that number of shares that exceeds the ownership limit (referred to as "excess shares") and . the Prohibited Transferee shall acquire no right or interest in such excess shares and . in the case of any event other than a purported transfer, the person or entity holding record title to any such shares in excess of the ownership limit (the "Prohibited Owner") shall cease to own any right or interest in such excess shares. Any such excess shares described above will be transferred automatically, by operation of law, to a trust, the beneficiary of which will be a qualified charitable organization selected by Host Marriott (the "Beneficiary"). Such automatic transfer shall be deemed to be effective as of the close of business on the business day prior to the date of such violating transfer. Within 20 days of receiving notice from Host Marriott of the transfer of shares to the trust, the trustee of the trust, who shall be designated by Host Marriott and be unaffiliated with Host Marriott and any Prohibited Transferee or Prohibited Owner, will be required to sell such excess shares to a person or entity who could own such shares without violating the ownership limit, and distribute to the Prohibited Transferee an amount equal to the lesser of the price paid by the Prohibited Transferee for such excess shares or the sales proceeds received by the trust for such excess shares. In the case of any excess shares resulting from any event other than a transfer, or from a transfer for no consideration, such as a gift, the trustee will be required to sell such excess shares to a qualified person or entity and distribute to 28

the Prohibited Owner an amount equal to the lesser of the fair market value of such excess shares as of the date of such event or the sales proceeds received by the trust for such excess shares. In either case, any proceeds in excess of the amount distributable to the Prohibited Transferee or Prohibited Owner, as applicable, will be distributed to the Beneficiary. Prior to a sale of any such excess shares by the trust, the trustee will be entitled to receive, in trust for the Beneficiary, all dividends and other distributions paid by Host Marriott with respect to such excess shares, and also will be entitled to exercise all voting rights with respect to such excess shares. Subject to Maryland law, effective as of the date that such shares have been transferred to the trust, the trustee shall have the authority to rescind as void any vote cast by a Prohibited Transferee prior to the discovery by Host Marriott that such shares have been transferred to the trust and to recast such vote in accordance with the desires of the trustee acting for the benefit of the Beneficiary. However, if Host Marriott has already taken irreversible corporate action, then the trustee shall not have the authority to rescind and recast such vote. Any dividend or other distribution paid to the Prohibited Transferee or Prohibited Owner, prior to the discovery by Host Marriott that such shares had been automatically transferred to a trust as described above, will be required to be repaid to the trustee upon demand for distribution to the Beneficiary. If the transfer to the trust as described above is not automatically effective to prevent violation of the ownership limit, then the Articles of Incorporation provides that the transfer of the excess shares will be void. In addition, shares of Host Marriott's stock held in the trust shall be deemed to have been offered for sale to Host Marriott, or its designee, at a price per share equal to the lesser of the price per share in the transaction that resulted in such transfer to the trust or, in the case of a devise or gift, the market value at the time of such devise or gift and the market value of such shares on the date Host Marriott, or its designee, accepts such offer. Host Marriott will have the right to accept such offer until the trustee has sold the shares held in the trust. Upon such a sale to Host Marriott, the interest of the Beneficiary in the shares sold will terminate and the trustee will distribute the net proceeds of the sale to the Prohibited Owner. The foregoing restrictions on transferability and ownership will not apply if the Board of Directors determines that it is no longer in the best interests of Host Marriott to attempt to qualify, or to continue to qualify, as a REIT. All certificates representing shares of Host Marriott's capital stock will bear a legend referring to the restrictions described above. All persons who own, directly or by virtue of the attribution provisions of the Internal Revenue Code, more than 5%, or such other percentage between 1/2 of 1% and 5% as provided in the rules and regulations under the Internal Revenue Code, of the lesser of the number or value of the outstanding shares of Host Marriott's capital stock must give a written notice to Host Marriott within 30 days after the end of each taxable year. In addition, each stockholder will, upon demand, be required to disclose to Host Marriott in writing such information with respect to the direct, indirect and constructive ownership of shares of Host Marriott's capital stock as the Board of Directors deems reasonably necessary to comply with the provisions of the Internal Revenue Code applicable to a REIT, to comply with the requirements of any taxing authority or governmental agency or to determine any such compliance. These ownership limitations could have the effect of delaying, deferring or preventing a takeover or other transaction in which holders of some, or a majority, of the common stock might receive a premium for their common stock over the then prevailing market price or which such holders might believe to be otherwise in their best interest. 29

DESCRIPTION OF DEPOSITARY SHARES General Host Marriott may issue depositary receipts for depositary shares, each of which will represent a fractional interest of a share of a particular series of preferred stock, as specified in the applicable prospectus supplement. Shares of preferred stock of each series represented by depositary shares will be deposited under a separate Deposit Agreement among Host Marriott and the depositary named therein. Subject to the terms of the Deposit Agreement, each owner of a depositary receipt will be entitled, in proportion to the fractional interest of a share of a particular series of preferred stock represented by the depositary shares evidenced by such depositary receipt, to all the rights and preferences of the preferred stock represented by such depositary shares, including dividend, voting, conversion, redemption and liquidation rights. The depositary shares will be evidenced by depositary receipts issued pursuant to the applicable Deposit Agreement. Immediately following the issuance and delivery of the preferred stock by Host Marriott to the depositary, Host Marriott will cause the depositary to issue, on behalf of Host Marriott, the depositary receipts. Copies of the applicable form of Deposit Agreement and depositary receipt may be obtained from Host Marriott upon request, and the statements made hereunder relating to the Deposit Agreement and the depositary receipts to be issued thereunder are summaries of certain provisions thereof and do not purport to be complete and are subject to, and qualified in their entirety by reference to, all of the provisions of the applicable Deposit Agreement and related depositary receipts. Dividends and Other Distributions The depositary will distribute all cash dividends or other cash distributions received in respect of the preferred stock to the record holders of depositary receipts evidencing the related depositary shares in proportion to the number of such depositary receipts owned by such holders, subject to certain obligations of holders to file proofs, certificates and other information and to pay certain charges and expenses to the depositary. In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary receipts entitled thereto, subject to certain obligations of holders to file proofs, certificates and other information and to pay certain charges and expenses to the depositary, unless the depositary determines that it is not feasible to make such distribution, in which case the depositary may, with the approval of Host Marriott, sell such property and distribute the net proceeds from such sale to such holders. No distribution will be made in respect of any depositary share to the extent that it represents any preferred stock converted into other securities. Withdrawal of Stock Upon surrender of the depositary receipts at the corporate trust office of the depositary (unless the related depositary shares have previously been called for redemption or converted into other securities), the holders thereof will be entitled to delivery at such office, to or upon such holder's order, of the number of whole or fractional shares of the preferred stock and any money or other property represented by the depositary shares evidenced by such depositary receipts. Holders of depositary receipts will be entitled to receive whole or fractional shares of the related preferred stock on the basis of the proportion of preferred stock represented by such depositary share as specified in the applicable prospectus supplement, but holders of such shares of preferred stock will not thereafter be entitled to receive depositary shares therefor. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of shares of preferred stock to be withdrawn, the depositary will deliver to such holder at the same time a new depositary receipt evidencing such excess number of depositary shares. 30

Redemption of Depositary Shares Whenever Host Marriott redeems shares of preferred stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing shares of the preferred stock so redeemed, provided Host Marriott shall have paid in full to the depositary the redemption price of the preferred stock to be redeemed plus an amount equal to any accrued and unpaid dividends thereon to the date fixed for redemption. The redemption price per depositary share will be equal to the corresponding proportion of the redemption price and any other amounts per share payable with respect to the preferred stock. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected pro rata (as nearly as may be practicable without creating fractional depositary shares) or by any other equitable method determined by Host Marriott. From and after the date fixed for redemption, all dividends in respect of the shares of preferred stock so called for redemption will cease to accrue, the depositary shares so called for redemption will no longer be deemed to be outstanding and all rights of the holders of the depositary receipts evidencing the depositary shares so called for redemption will cease, except the right to receive any moneys payable upon such redemption and any money or other property to which the holders of such depositary receipts were entitled upon such redemption and surrender thereof to the depositary. Voting of the Preferred Stock Upon receipt of notice of any meeting at which the holders of the preferred stock are entitled to vote, the depositary will mail the information contained in such notice of meeting to the record holders of the depositary receipts evidencing the depositary shares which represent such preferred stock. Each record holder of depositary receipts evidencing depositary shares on the record date, which will be the same date as the record date for the preferred stock, will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of preferred stock represented by such holder's depositary shares. The depositary will vote the amount of preferred stock represented by such depositary shares in accordance with such instructions, and Host Marriott will agree to take all reasonable action which may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary will abstain from voting the amount of preferred stock represented by such depositary shares to the extent it does not receive specific instructions from the holders of depositary receipts evidencing such depositary shares. The depositary shall not be responsible for any failure to carry out any instruction to vote, or for the manner or effect of any such vote made, as long as such action or non-action is in good faith and does not result from negligence or willful misconduct of the depositary. Liquidation Preference In the event of the liquidation, dissolution or winding up of Host Marriott, whether voluntary or involuntary, the holders of each depositary receipt will be entitled to the fraction of the liquidation preference accorded each share of preferred stock represented by the depositary shares evidenced by such depositary receipt, as set forth in the applicable prospectus supplement. Conversion of Preferred Stock The depositary shares, as such, are not convertible into common stock or any other securities or property of Host Marriott. Nevertheless, if so specified in the applicable prospectus supplement relating to an offering of depositary shares, the depositary receipts may be surrendered by holders thereof to the depositary with written instructions to the depositary to instruct Host Marriott to cause conversion of the preferred stock represented by the depositary shares evidenced by such depositary receipts into whole shares of common stock, other shares of preferred stock of Host Marriott or other shares of stock, and Host Marriott has agreed that upon receipt of such instructions and any amounts payable in respect thereof, it will cause the conversion thereof utilizing the same procedures as those provided for delivery of preferred stock to effect such conversion. If the depositary shares evidenced by a depositary receipt are to be converted in part only, a new depositary receipt or receipts will be issued for any depositary shares not to be converted. No fractional shares of common stock will be 31

issued upon conversion, and if such conversion would result in a fractional share being issued, an amount will be paid in cash by Host Marriott equal to the value of the fractional interest based upon the closing price of the common stock on the last business day prior to the conversion. Amendment and Termination of the Deposit Agreement The form of depositary receipt evidencing the depositary shares which represent the preferred stock and any provision of the Deposit Agreement may at any time be amended by agreement between Host Marriott and the depositary. However, any amendment that materially and adversely alters the rights of the holders of depositary receipts or that would be materially and adversely inconsistent with the rights granted to the holders of the related preferred stock will not be effective unless such amendment has been approved by the existing holders of at least 66% of the depositary shares evidenced by the depositary receipts then outstanding. No amendment shall impair the right, subject to certain exceptions in the Deposit Agreement, of any holder of depositary receipts to surrender any depositary receipt with instructions to deliver to the holder the related preferred stock and all money and other property, if any, represented thereby, except in order to comply with law. Every holder of an outstanding depositary receipt at the time any such amendment becomes effective shall be deemed, by continuing to hold such receipt, to consent and agree to such amendment and to be bound by the Deposit Agreement as amended thereby. The Deposit Agreement may be terminated by Host Marriott upon not less than 30 days prior written notice to the depositary if a majority of each series of preferred stock affected by such termination consents to such termination, whereupon the depositary shall deliver or make available to each holder of Depositary Receipts, upon surrender of the depositary receipts held by such holder, such number of whole or fractional shares of preferred stock as are represented by the depositary shares evidenced by such depositary receipts together with any other property held by the depositary with respect to such depositary receipt. In addition, the Deposit Agreement will automatically terminate if . all outstanding depositary shares shall have been redeemed, . there shall have been a final distribution in respect of the related preferred stock in connection with any liquidation, dissolution or winding up of Host Marriott and such distribution shall have been distributed to the holders of depositary receipts evidencing the depositary shares representing such preferred stock or . each share of the related preferred stock shall have been converted into securities of Host Marriott not so represented by depositary shares. Charges of Preferred Stock Depositary Host Marriott will pay all transfer and other taxes and governmental charges arising solely from the existence of the Deposit Agreement. In addition, Host Marriott will pay the fees and expenses of the depositary in connection with the performance of its duties under the Deposit Agreement. However, holders of depositary receipts will pay the fees and expenses of the depositary for any duties requested by such holders to be performed which are outside of those expressly provided for in the Deposit Agreement. Resignation and Removal of Depositary The depositary may resign at any time by delivering to Host Marriott notice of its election to do so, and Host Marriott may at any time remove the depositary, any such resignation or removal to take effect upon the appointment of a successor depositary. A successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50,000,000. Miscellaneous The depositary will forward to holders of depositary receipts any reports and communications from Host Marriott which are received by the depositary with respect to the related preferred stock. 32

Neither the depositary nor Host Marriott will be liable if it is prevented from or delayed in, by law or any circumstances beyond its control, performing its obligations under the Deposit Agreement. The obligations of Host Marriott and the depositary under the Deposit Agreement will be limited to performing their duties thereunder in good faith and without negligence, in the case of any action or inaction in the voting of preferred stock represented by the depositary shares, gross negligence or willful misconduct, and Host Marriott and the depositary will not be obligated to prosecute or defend any legal proceeding in respect of any depositary receipts, depositary shares or shares of preferred stock represented thereby unless satisfactory indemnity is furnished. Host Marriott and the depositary may rely on written advice of counsel or accountants, or information provided by persons presenting shares of preferred stock represented thereby for deposit, holders of depositary receipts or other persons believed in good faith to be competent to give such information, and on documents believed in good faith to be genuine and signed by a proper party. In the event the depositary shall receive conflicting claims, requests or instructions from any holders of depositary receipts, on the one hand, and Host Marriott, on the other hand, the depositary shall be entitled to act on such claims, requests or instructions received from Host Marriott. 33

DESCRIPTION OF WARRANTS General Host Marriott may issue warrants to purchase preferred stock, depositary shares or common stock. Warrants may be issued independently or together with any offered securities and may be attached to or separate from such offered securities. The warrants are to be issued under Warrant Agreements to be entered into between Host Marriott and a bank or trust company, as warrant agent, all as shall be set forth in the prospectus supplement relating to the warrants being offered pursuant thereto. The warrant agent will act solely as an agent of Host Marriott in connection with the warrants of such series and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

DESCRIPTION OF SUBSCRIPTION RIGHTS General Host Marriott may issue subscription rights to purchase common stock, preferred stock, depositary shares or warrants to purchase preferred stock or common stock. Subscription rights may be issued independently or together with any other offered security and may or may not be transferable by the purchaser receiving the subscription rights. In connection with any subscription rights offering to Host Marriott's stockholders, Host Marriott may enter into a standby underwriting arrangement with one or more underwriters pursuant to which such underwriter will purchase any offered securities remaining unsubscribed for after such subscription rights offering. In connection with a subscription rights offering to Host Marriott's stockholders, certificates evidencing the subscription rights and a prospectus supplement will be distributed to Host Marriott's stockholders on the record date for receiving subscription rights in such subscription rights offering set by Host Marriott.

In the event that not all of the subscription rights issued in any offering are exercised, Host Marriott may determine to offer any unsubscribed 35

offered securities directly to persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby underwriting arrangements, as set forth in the applicable prospectus supplement. FEDERAL INCOME TAX CONSIDERATIONS Introduction The following discussion summarizes the federal income tax considerations reasonably anticipated to be material to a stockholder in connection with the purchase, ownership and disposition of common stock. The applicable prospectus supplement will contain information about additional federal income tax considerations, if any, relating to particular offerings. The following discussion is intended to address only those federal income tax consequences that are generally relevant to all stockholders. Accordingly, it does not discuss all aspects of federal income taxation that might be relevant to a specific stockholder in light of his particular investment or tax circumstances. Therefore, it is imperative that a stockholder review the following discussion and consult with his own tax advisors to determine the interaction of his individual tax situation with the tax considerations associated with the purchase, ownership and disposition of common stock. The following discussion provides general information only, is not exhaustive of all possible tax considerations and is not tax advice. For example, this summary does not give a detailed description of any state, local or foreign tax considerations. In addition, the discussion does not purport to deal with all aspects of taxation that may be relevant to a stockholder subject to special treatment under the federal income tax laws, including, without limitation, insurance companies, financial institutions or broker-dealers, tax- exempt organizations or foreign corporations and persons who are not citizens or residents of the United States. The information in this section is based on the Internal Revenue Code, current, temporary and proposed regulations thereunder, the legislative history of the Internal Revenue Code, current administrative interpretations and practices of the IRS, including its practices and policies as endorsed in private letter rulings, which are not binding on the IRS, and court decisions, all as of the date hereof. No assurance can be given that future legislation, regulations, administrative interpretations and court decisions will not significantly change the current law or adversely affect existing interpretations of current law. Any such change could apply retroactively to transactions preceding the date of the change. No assurance can be provided that the statements set forth herein will not be challenged by the IRS or will be sustained by a court if so challenged. Hogan & Hartson has given Host Marriott an opinion to the effect that the discussion herein under the heading "Federal Income Tax Considerations," to the extent that it contains descriptions of applicable federal income tax law, is correct in all material respects. The opinion, however, does not purport to address the actual tax consequences of the purchase, ownership and disposition of common stock to any particular stockholder. The opinion is based on the Internal Revenue Code and regulations in effect on the date hereof, current administrative interpretations and positions of the IRS and existing court decisions. No assurance can be given that future legislation, regulations, administrative interpretations and court decisions will not significantly change the law on which the above opinion is based. Any such change could adversely affect the opinion. In addition, any such change could apply retroactively. Moreover, opinions of counsel merely represent counsel's best judgment with respect to the probable outcome on the merits and are not binding on the IRS or the courts. Accordingly, even if there is no change in applicable law, no assurance can be provided that such opinion, which does not bind the IRS or the courts, will not be challenged by the IRS or will be sustained by a court if so challenged. The specific tax attributes of a particular stockholder could have a material impact on the tax considerations associated with the purchase, ownership and disposition of common stock. Therefore, it is essential that each prospective stockholder consult with his own tax advisors with regard to the application of the federal income tax laws to such stockholder's personal tax situation, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction. 36

Federal Income Taxation of Host Marriott General. Host Marriott plans to make an election to be taxed as a REIT under Sections 856 through 859 of the Internal Revenue Code, effective for the taxable year beginning January 1, 1999. Host Marriott intends that, commencing with such year, it will be organized and will operate in such a manner as to qualify for taxation as a REIT, but no assurance can be given that it in fact will qualify or remain qualified as a REIT. The sections of the Internal Revenue Code and the corresponding regulations that govern the federal income tax treatment of a REIT and its stockholders are highly technical and complex. The following discussion is a summary of the material aspects of these rules, which is qualified in its entirety by the applicable Internal Revenue Code provisions, rules and regulations promulgated thereunder, and administrative and judicial interpretations thereof. Hogan & Hartson has provided to Host Marriott an opinion to the effect that Host Marriott will be organized in conformity with the requirements for qualification as a REIT, and, beginning in 1999, its proposed method of operation will enable it to meet the requirements for qualification and taxation as a REIT under the Internal Revenue Code. It must be emphasized that this opinion is conditioned upon certain assumptions and representations made by Host Marriott and Host Marriott, L.P. as to factual matters relating to the organization and operation of Host Marriott and its subsidiaries, Host Marriott, L.P. and its subsidiaries, the non-controlled subsidiaries, the Host Employee/Charitable Trust and Crestline and its subsidiaries, including the economic and other terms of each lease and the expectations of Host Marriott and the lessees with respect thereto. This opinion also is based on the timely completion of all of the transactions comprising the REIT conversion, which are described in detail in certain documents that are incorporated by reference into this prospectus. See "Where You Can Find More Information." This generally means that all of the transactions are completed prior to end of 1998, except for those transactions that clearly are contemplated to be completed afterward. In addition, this opinion is based upon the factual representations of Host Marriott concerning its business and properties as described in, or incorporated by reference into, this prospectus. Moreover, qualification and taxation as a REIT depends upon Host Marriott's ability to meet the various qualification tests imposed under the Internal Revenue Code discussed below. Hogan & Hartson will not review Host Marriott's operating results. Accordingly, no assurance can be given that the actual results of Host Marriott's operations for any particular taxable year will satisfy such requirements. Further, the anticipated income tax treatment described below may be changed, perhaps retroactively, by legislative, administrative or judicial action at any time. See "--Failure of Host Marriott to Qualify as a REIT" below. If Host Marriott qualifies for taxation as a REIT, it generally will not be subject to federal corporate income taxes on its net income that it currently distributes to its stockholders. This treatment substantially eliminates the "double taxation" at the corporate and stockholder levels that generally results from an investment in a regular corporation. However, Host Marriott will be subject to federal income tax as follows: 1. Host Marriott will be taxed at regular corporate rates on any undistributed "REIT taxable income," including undistributed net capital gains; provided, however, that properly designated undistributed capital gains will effectively avoid taxation at the stockholder level. A REIT's "REIT taxable income" is the otherwise taxable income of the REIT subject to certain adjustments, including a deduction for dividends paid. 2. Under certain circumstances, Host Marriott may be subject to the "alternative minimum tax" on its items of tax preference. 3. If Host Marriott has net income from the sale or other disposition of "foreclosure property" which is held primarily for sale to customers in the ordinary course of business or other nonqualifying income from foreclosure property, it will be subject to tax at the highest corporate rate on such income. 4. Host Marriott's net income from "prohibited transactions" will be subject to a 100% tax. In general, "prohibited transactions" are certain sales or other dispositions of property held primarily for sale to customers in the ordinary course of business other than foreclosure property. 37

5. If Host Marriott fails to satisfy the 75% gross income test or the 95% gross income test discussed below, but nonetheless maintains its qualification as a REIT because certain other requirements are met, it will be subject to a tax equal to (1) the gross income attributable to the greater of the amount by which Host Marriott fails the 75% or 95% test multiplied by (2) a fraction intended to reflect its profitability. 6. If Host Marriott fails to distribute during each calendar year at least the sum of (1) 85% of its REIT ordinary income for such year, (2) 95% of its REIT capital gain net income for such year and (3) any undistributed taxable income from prior periods, Host Marriott will be subject to a 4% excise tax on the excess of such required distribution over the sum of amounts actually distributed and amounts retained but with respect to which federal income tax was paid. 7. If Host Marriott acquires any asset from a taxable "C" corporation in a transaction in which the basis of the asset in the hands of Host Marriott is determined by reference to the basis of the asset in the hands of the "C" corporation, and Host Marriott recognizes gain on the disposition of such asset during the ten-year period beginning on the date on which such asset was acquired by Host Marriott (the "Recognition Period"), then, to the extent of the asset's "built-in gain," such gain will be subject to tax at the highest regular corporate rate applicable. Built-in gain is the excess of the fair market value of an asset over Host Marriott's adjusted basis in the asset, determined when Host Marriott acquired the asset. Host Marriott owns an indirect interest in appreciated assets that its predecessors held before the REIT conversion. Such appreciated assets have a "carryover" basis and thus have built-in gain with respect to Host Marriott. If such appreciated property is sold within the ten-year period following the REIT conversion, Host Marriott generally will be subject to regular corporate tax on that gain to the extent of the built-in gain in that property at the time of the REIT conversion. The total amount of gain on which Host Marriott can be taxed is limited to the excess of the aggregate fair market value of its assets on January 1, 1999 over the adjusted tax bases of those assets at that time. This tax could be very material, however, and may result in the Host Marriott, L.P. and Host Marriott seeking to avoid a taxable disposition of any significant asset owned by the Host Predecessors at the time of the REIT conversion for the ten taxable years following the REIT conversion even though such disposition might otherwise be in the best interests of Host Marriott. Notwithstanding Host Marriott's status as a REIT, it is likely that substantial deferred liabilities of its predecessors will be recognized over the next ten years. Deferred liabilities include, but are not limited to, tax liabilities attributable to built-in gain assets and deferred tax liabilities attributable to taxable income for which neither Host Marriott nor Host Marriott, L.P. will receive corresponding cash. In addition, the IRS could assert substantial additional liabilities for taxes against Host Marriott's predecessors for taxable years prior to the time Host Marriott qualifies as a REIT. Under the terms of the REIT conversion and the partnership agreement of Host Marriott, L.P., Host Marriott, L.P. will be responsible for paying, or reimbursing Host Marriott for the payment of all such tax liabilities as well as any other liabilities, including contingent liabilities and liabilities attributable to litigation that Host Marriott may incur, whether such liabilities are incurred by reason of activities prior to the REIT conversion or activities subsequent thereto. Host Marriott, L.P. will pay, or reimburse Host Marriott for the payment of all taxes incurred by Host Marriott, except for taxes imposed on Host Marriott by reason of its failure to qualify as a REIT or to distribute to its stockholders an amount equal to its "REIT taxable income," including net capital gains. This obligation by Host Marriott, L.P. includes any federal corporate income tax imposed on built-in gain. Requirements for Qualification. The Internal Revenue Code defines a REIT as a corporation, trust or association (1) which is managed by one or more directors or trustees; (2) the beneficial ownership of which is evidenced by transferable shares or by transferable certificates of beneficial interest; (3) which would be taxable as a domestic corporation, but for Sections 856 through 859 of the Internal Revenue Code; 38

(4) which is neither a financial institution nor an insurance company subject to certain provisions of the Internal Revenue Code; (5) the beneficial ownership of which is held by 100 or more persons; (6) during the last half of each taxable year not more than 50% in value of the outstanding stock of which is owned, actually or constructively, by five or fewer individuals (as defined in the Internal Revenue Code to include certain entities); and (7) which meets certain other tests, described below, regarding the nature of its income and assets. Conditions (1) to (4), inclusive, must be met during the entire taxable year and condition (5) must be met during at least 335 days of a taxable year of twelve months, or during a proportionate part of a taxable year of less than twelve months. Conditions (5) and (6) will not apply until after the first taxable year for which Host Marriott makes the election to be taxed as a REIT. For purposes of conditions (5) and (6), pension funds and certain other tax- exempt entities are treated as individuals, subject to a "look-through" exception in the case of condition (6). Compliance with condition (5) shall be determined by disregarding the ownership of Host Marriott shares by any person(s) who: (a) acquired such shares as a gift or bequest or pursuant to a legal separation or divorce; (b) is the estate of any person making such transfer to the estate; or (c) is a company established exclusively for the benefit of (or wholly owned by) either the person making such transfer or a person described in (a) or (b). In connection with condition (6), Host Marriott is required to send annual letters to its stockholders requesting information regarding the actual ownership of its shares. If Host Marriott complies with this requirement, and it does not know, or exercising reasonable diligence would not have known, whether it failed to meet condition (6), then it will be treated as having met condition (6). If Host Marriott fails to send such annual letters, it will be required to pay either a $25,000 penalty or, if the failure is intentional, a $50,000 penalty. The IRS may require Host Marriott, under those circumstances, to take further action to ascertain actual ownership of its shares, and failure to comply with such an additional requirement would result in an additional $25,000 (or $50,000) penalty. No penalty would be assessed in the first instance, however, if the failure to send the letters is due to reasonable cause and not to willful neglect. Host Marriott believes that it meets and will continue to meet conditions (1) through (4). In addition, Host Marriott believes that it will have outstanding (commencing with its first taxable year as a REIT) common stock with sufficient diversity of ownership to allow it to satisfy conditions (5) and (6). With respect to condition (6), Host Marriott intends to comply with the requirement that it send annual letters to its stockholders requesting information regarding the actual ownership of its shares. In addition, the Host Marriott Articles of Incorporation contains an ownership limit, which is intended to assist Host Marriott in continuing to satisfy the share ownership requirements described in (5) and (6) above. See "Restrictions on Ownership and Transfer." The ownership limit, together with compliance with the annual stockholder letter requirement described above, however, may not ensure that Host Marriott will, in all cases, be able to satisfy the share ownership requirements described above. If Host Marriott fails to satisfy such share ownership requirements, Host Marriott will not qualify as a REIT. See "-- Failure of Host Marriott to Qualify as a REIT." A corporation may not elect to become a REIT unless its taxable year is the calendar year. Although Host Marriott previously had a 52-53 week year ending on the Friday closest to January 1, it adopted a calendar year taxable year in connection with the REIT conversion. Distribution of "Earnings and Profits" Attributable to "C" Corporation Taxable Years. A REIT cannot have at the end of any taxable year any undistributed earnings and profits ("E&P") that are attributable to a "C" corporation taxable year, which includes all undistributed E&P of Host Marriott's predecessors. Accordingly, Host Marriott has until December 31, 1999 to distribute such E&P. In connection with the REIT conversion, Host Marriott declared dividends intended to eliminate the substantial majority, if not all, of such E&P. To the extent, however, that any such E&P remains (the "Acquired Earnings"), Host Marriott is required to distribute such E&P prior to the end of 1999. Failure to do so would result in disqualification of Host 39

Marriott as a REIT at least for 1999. If Host Marriott should be so disqualified for 1999, subject to the satisfaction by Host Marriott of certain "deficiency dividend" procedures described below in "--Annual Distribution Requirements Applicable to REITs" and assuming that Host Marriott otherwise satisfies the requirements for qualification as a REIT, Host Marriott should qualify as a REIT for 2000 and thereafter. Host Marriott believes that the dividends it has already declared will be sufficient to distribute all of the Acquired Earnings as of December 31, 1999. However, there are substantial uncertainties relating to both the estimate of the Acquired Earnings, as described below, and the value of noncash consideration that Host Marriott has distributed or will distribute. Accordingly, there can be no assurance this requirement will be met. The estimated amount of the Acquired Earnings will be based on the allocated consolidated E&P of Host Marriott's predecessors accumulated from 1929 through and including 1998 and taking into account the allocation, as a matter of law, of 81% of Host Marriott's predecessors' accumulated E&P to Marriott International on October 8, 1993 in connection with the spin-off of Marriott International. The estimate was determined based on the available tax returns and certain assumptions with respect to both such returns and other matters. The calculation of the Acquired Earnings, however, depends upon a number of factual and legal interpretations related to the activities and operations of Host Marriott's predecessors during their entire corporate existence and is subject to review and challenge by the IRS. There can be no assurance that the IRS will not examine the tax returns of Host Marriott's predecessors and propose adjustments to increase their taxable income. The impact of such proposed adjustments, if any, may be material. If the IRS examines Host Marriott's calculation of its E&P, the IRS can consider all taxable years of Host Marriott's predecessors as open for review for purposes of such determination. Hogan & Hartson has expressed no opinion as to the amount of E&P of Host Marriott and Host Marriott's predecessors. Accordingly, for purposes of its opinion as to the qualification of Host Marriott as a REIT following the REIT conversion, Hogan & Hartson is relying upon a representation from Host Marriott that by the end of 1999 it will have eliminated all Acquired Earnings. Qualified REIT Subsidiary. If a REIT owns a corporate subsidiary that is a "qualified REIT subsidiary," that subsidiary will be disregarded for federal income tax purposes, and all assets, liabilities and items of income, deduction and credit of the subsidiary will be treated as assets, liabilities and items of the REIT itself. Generally, a qualified REIT subsidiary is a corporation all of the capital stock of which is owned by one REIT. Host Marriott holds several qualified REIT subsidiaries that hold de minimis indirect interests in the partnerships that own hotels. These entities will not be subject to federal corporate income taxation, although they may be subject to state and local taxation in certain jurisdictions. Ownership of Partnership Interests by a REIT. A REIT which is a partner in a partnership will be deemed to own its proportionate share of the assets of the partnership and will be deemed to be entitled to the income of the partnership attributable to such share. In addition, the character of the assets and gross income of the partnership shall retain the same character in the hands of the REIT for purposes of Section 856 of the Internal Revenue Code, including satisfying the gross income tests and the asset tests. Thus, Host Marriott's proportionate share of the assets and items of income of Host Marriott, L.P., including Host Marriott, L.P.'s share of such items of any subsidiaries that are partnerships or LLCs, are treated as assets and items of income of Host Marriott for purposes of applying the requirements described herein. A summary of the rules governing the federal income taxation of partnerships and their partners is provided below in "--Tax Aspects of Ownership of Interests in Host Marriott, L.P." As the sole general partner of Host Marriott, L.P., Host Marriott has direct control over Host Marriott, L.P. and indirect control over the subsidiaries in which Host Marriott, L.P. or a subsidiary has a controlling interest. Host Marriott intends to operate these entities consistent with the requirements for qualification of Host Marriott as a REIT. Income Tests Applicable to REITs. In order to maintain qualification as a REIT, Host Marriott must satisfy two gross income requirements. First, at least 75% of Host Marriott's gross income, excluding gross income from "prohibited transactions," for each taxable year must be derived directly or indirectly from 40

investments relating to real property or mortgages on real property, including "rents from real property" and, in certain circumstances, interest, or from certain types of temporary investments. Second, at least 95% of Host Marriott's gross income, excluding gross income from "prohibited transactions," for each taxable year must be derived from any combination of such real property investments, dividends, interest, certain hedging instruments and gain from the sale or disposition of stock or securities, including certain hedging instruments. Rents paid pursuant to Host Marriott's leases, together with dividends and interest received from the non-controlled subsidiaries, will constitute substantially all of the gross income of Host Marriott. Several conditions must be satisfied in order for rents received by Host Marriott, including the rents received pursuant to the leases, to qualify as "rents from real property." First, the amount of rent must not be based in whole or in part on the income or profits of any person. However, an amount received or accrued generally will not be excluded from the term "rents from real property" solely by reason of being based on a fixed percentage or percentages of receipts or sales. Second, rents received from a tenant will not qualify as "rents from real property" if Host Marriott, or an actual or constructive owner of 10% or more of Host Marriott, actually or constructively owns 10% or more of such tenant (a "Related Party Tenant"). Third, if rent attributable to personal property leased in connection with a lease of real property is greater than 15% of the total rent received under the lease, then the portion of rent attributable to such personal property will not qualify as "rents from real property." Finally, if Host Marriott operates or manages a property or furnishes or renders services to the tenants at the property other than through an independent contractor from whom Host Marriott derives no revenue, excluding for these purposes services "usually or customarily rendered" in connection with the rental of real property and not otherwise considered "rendered to the occupant," and the income derived from such services (the "Impermissible Service Income") exceeds one percent of the total amount received by Host Marriott with respect to the property, then no amount received by Host Marriott with respect to the property will qualify as "rents from real property." For these purposes, Impermissible Service Income cannot be less than 150% of the cost of providing the service. If the Impermissible Service Income is one percent or less of the total amount received by the REIT with respect to the property, then only the Impermissible Service Income will not qualify as "rents from real property." To the extent that services other than those customarily furnished or rendered in connection with the rental of real property are rendered to the tenants of the property by an independent contractor, the cost of the services must be borne by the independent contractor. Host Marriott, L.P. and each subsidiary that owns hotels have entered into leases with subsidiaries of Crestline, pursuant to which the hotels are leased for a term ranging generally from seven to ten years commencing on January 1, 1999. Each lease provides for thirteen payments per annum of a specified base rent plus, to the extent that it exceeds the base rent, additional rent which is calculated based upon the gross sales of the hotels subject to the lease, plus certain other amounts. Neither Host Marriott nor Host Marriott, L.P. intends to do any of the following: . provide any services to the lessees with respect to the operation of the hotels; . charge rent for any hotel that is based in whole or in part on the income or profits of any person, except for the Harbor Beach Resort, where the lease provides for rent based upon net profits, but which Host Marriott currently believes will not jeopardize Host Marriott's status as a REIT; . rent any hotel to a Related Party Tenant unless the Board of Directors determines in its discretion that the rent received from such Related Party Tenant is not material and will not jeopardize Host Marriott's status as a REIT; or . derive rental income attributable to personal property other than personal property leased in connection with the lease of real property, the amount of which is less than 15% of the total rent received under the lease, unless the Board of Directors determines in its discretion that the amount of such rent attributable to personal property is not material and will not jeopardize Host Marriott's status as a REIT. 41

In order for the rent paid pursuant to the leases to constitute "rents from real property," the lessees must not be regarded as Related Party Tenants, and the leases must be respected as true leases for federal income tax purposes. Accordingly the lessee cannot be treated as service contracts, joint ventures or some other type of arrangement. A lessee will be regarded as a Related Party Tenant only if Host Marriott and/or one or more actual or constructive owners of 10% or more of Host Marriott, actually or constructively, own 10% or more of such lessee through an ownership interest in Crestline. In order to help preclude the lessees from being regarded as Related Party Tenants, the following organizational documents contain the following ownership limits: . the articles of incorporation of Crestline expressly prohibit any person or persons acting as a group, including Host Marriott and/or any 10% or greater stockholder of Host Marriott, from owning more than 9.8% of the lesser of the number or value of the shares of capital stock of Crestline; . the Host Marriott Articles of Incorporation expressly prohibits any person or persons acting as a group or entity from owning, actually and/or constructively, more than 9.8% of the lesser of the number or value of capital stock of Host Marriott (subject to a limited exception for a holder of shares of capital stock of Host Marriott solely by reason of the Merger in excess of the ownership limit so long as the holder thereof did not own, directly or by attribution under the Internal Revenue Code, more than 9.9% in value of the outstanding shares of capital stock of Host Marriott) or any other class or series of shares of Host Marriott; and . Host Marriott, L.P.'s partnership agreement expressly prohibits any person, or persons acting as a group, or entity, other than Host Marriott and an affiliate of the The Blackstone Group and a series of related funds controlled by Blackstone Real Estate Partners (the "Blackstone Entities"), from owning more than 4.9% by value of any class of interests in Host Marriott, L.P. Each of these prohibitions contains self-executing enforcement mechanisms. Assuming that these prohibitions are enforced at all times and no waivers thereto are granted, the lessees should not be regarded as Related Party Tenants. There can be no assurance, however, that these ownership restrictions will be enforced in accordance with their terms in all circumstances or otherwise will ensure that the lessees will not be regarded as Related Party Tenants. The determination of whether the leases are true leases depends upon an analysis of all the surrounding facts and circumstances. In making such a determination, courts have considered a variety of factors, including the following: . the intent of the parties; . the form of the agreement; . the degree of control over the property that is retained by the property owner (e.g., whether the lessee has substantial control over the operation of the property or whether the lessee was required simply to use its best efforts to perform its obligations under the agreement); and . the extent to which the property owner retains the risk of loss with respect to the property (e.g., whether the lessee bears the risk of increases in operating expenses or the risk of damage to the property) or the potential for economic gain (e.g., appreciation) with respect to the property. In addition, Section 7701(e) of the Internal Revenue Code provides that a contract that purports to be a service contract or a partnership agreement is treated instead as a lease of property if the contract is properly treated as such, taking into account all relevant factors. Since the determination of whether a service contract should be treated as a lease is inherently factual, the presence or absence of any single factor may not be dispositive in every case. Some of the relevant factors include whether: . the service recipient is in physical possession of the property; . the service recipient controls the property; . the service recipient has a significant economic or possessory interest in the property (e.g., the property's use is likely to be dedicated to the service recipient for a substantial portion of the useful 42

life of the property, the recipient shares the risk that the property will decline in value, the recipient shares in any appreciation in the value of the property, the recipient shares in savings in the property's operating costs or the recipient bears the risk of damage to or loss of the property); . the service provider does not bear any risk of substantially diminished receipts or substantially increased expenditures if there is nonperformance under the contract; . the service provider does not use the property concurrently to provide significant services to entities unrelated to the service recipient; and . the total contract price does not substantially exceed the rental value of the property for the contract period. Host Marriott's leases have been structured with the intent to qualify as true leases for federal income tax purposes. For example, with respect to each lease: . Host Marriott, L.P. or the applicable subsidiary or other lessor entity and the lessee intend for their relationship to be that of a lessor and lessee and such relationship is documented by a lease agreement, . the lessee has the right to exclusive possession and use and quiet enjoyment of the hotels covered by the lease during the term of the lease, . the lessee bears the cost of, and will be responsible for, day-to-day maintenance and repair of the hotels other than the cost of certain capital expenditures, and will dictate through the hotel managers, who work for the lessees during the terms of the leases, how the hotels are operated and maintained, . the lessee bears all of the costs and expenses of operating the hotels, including the cost of any inventory used in their operation, during the term of the lease, other than the cost of certain furniture, fixtures and equipment, and certain capital expenditures, . the lessee benefits from any savings and bears the burdens of any increases in the costs of operating the hotels during the term of the lease, . in the event of damage or destruction to a hotel, the lessee is at economic risk because it will bear the economic burden of the loss in income from operation of the hotels subject to the right, in certain circumstances, to terminate the lease if the lessor does not restore the hotel to its prior condition, . the lessee has indemnified Host Marriott, L.P. or the applicable subsidiary against all liabilities imposed on Host Marriott, L.P. or the applicable subsidiary during the term of the lease by reason of (A) injury to persons or damage to property occurring at the hotels or (B) the lessee's use, management, maintenance or repair of the hotels, . the lessee is obligated to pay, at a minimum, substantial Base Rent for the period of use of the hotels under the lease, . the lessee stands to incur substantial losses or reap substantial gains depending on how successfully it, through the hotel managers, who work for the lessees during the terms of the leases, operates the hotels, . Host Marriott and Host Marriott, L.P. believe that each lessee reasonably expects to derive a meaningful profit, after expenses and taking into account the risks associated with the lease, from the operation of the hotels during the term of its leases, and . upon termination of each lease, the applicable hotel is expected to have a remaining useful life equal to at least 20% of its expected useful life on the date of the consummation of the REIT conversion, and a fair market value equal to at least 20% of its fair market value on the date of the consummation of the REIT conversion. If, however, the leases were recharacterized as service contracts or partnership agreements, rather than true leases, or disregarded altogether for tax purposes, all or part of the payments that Host Marriott, L.P. receives from the lessees would not be considered rent or would not otherwise satisfy the various requirements for qualification as "rents from real property." In that case, Host Marriott very likely would not be able to satisfy either the 75% or 95% gross income tests and, as a result, would lose its REIT status. 43

As indicated above, "rents from real property" must not be based in whole or in part on the income or profits of any person. Payments made pursuant to Host Marriott's leases should qualify as "rents from real property" since they are based on either fixed dollar amounts or on specified percentages of gross sales fixed at the time the leases were entered into, except for the Harbor Beach Resort, which lease provides for rents based upon net profits. The foregoing assumes that the leases are not renegotiated during their term in a manner that has the effect of basing either the percentage rent or base rent on income or profits. The foregoing also assumes that the leases are not in reality used as a means of basing rent on income or profits. More generally, the rent payable under the leases will not qualify as "rents from real property" if, considering the leases and all the surrounding circumstances, the arrangement does not conform with normal business practice. Host Marriott intends that it will not renegotiate the percentages used to determine the percentage rent during the terms of the leases in a manner that has the effect of basing rent on income or profits. In addition, Host Marriott believes that the rental provisions and other terms of the leases conform with normal business practice and, other than the Harbor Beach Resort lease, were not intended to be used as a means of basing rent on income or profits. Furthermore, Host Marriott intends that, with respect to other properties that it acquires in the future, it will not charge rent for any property that is based in whole or in part on the income or profits of any person, except by reason of being based on a fixed percentage of gross revenues, as described above. Host Marriott leases certain items of personal property to the lessees in connection with its leases. Under the Internal Revenue Code, if a lease provides for the rental of both real and personal property and the portion of the rent attributable to personal property is 15% or less of the total rent due under the lease, then all rent paid pursuant to such lease qualifies as "rent from real property." If, however, a lease provides for the rental of both real and personal property, and the portion of the rent attributable to personal property exceeds 15% of the total rent due under the lease, then the portion of the rent that is attributable to personal property does not qualify as "rent from real property." The amount of rent attributable to personal property is that amount which bears the same ratio to total rent for the taxable year as the average of the adjusted tax bases of the personal property at the beginning and end of the year bears to the average of the aggregate adjusted tax bases of both the real and personal property at the beginning and end of such year. Host Marriott has represented that, with respect to each of its leases that includes a lease of items of personal property, the amount of rent attributable to personal property with respect to such lease, determined as set forth above, will not exceed 15% of the total rent due under the lease (except for a relatively small group of leases where the rent attributable to personal property, which would constitute non-qualifying income for purposes of the 75% and 95% gross income tests, would not be material relative to the overall gross income of Host Marriott). Each lease permits Host Marriott, L.P. to take certain measures, including requiring the lessee to purchase certain furniture, fixtures and equipment or to lease such property from a third party, including a non-controlled subsidiary, if necessary to ensure that all of the rent attributable to personal property with respect to such lease will qualify as "rent from real property." In order to protect Host Marriott's ability to qualify as a REIT, Host Marriott, L.P. sold substantial personal property associated with a number of hotels acquired in connection with the REIT conversion to a non-controlled subsidiary. The non-controlled subsidiary separately leases all such personal property directly to the applicable lessee and receives rental payments which Host Marriott believes represent the fair rental value of such personal property directly from the lessees. If such arrangements are not respected for federal income tax purposes, Host Marriott likely would not qualify as a REIT. If any of the hotels were to be operated directly by Host Marriott, L.P. or a subsidiary as a result of a default by a lessee under the applicable lease, such hotel would constitute foreclosure property until the close of the third tax year following the tax year in which it was acquired, or for up to an additional three years if an extension is granted by the IRS, provided that: (1) the operating entity conducts operations through an independent contractor, which might, but would not necessarily in all circumstances, include Marriott International and its subsidiaries, within 90 days after the date the hotel is acquired as the result of a default by a lessee, (2) the operating entity does not undertake any construction on the foreclosed property other than completion of improvements that were more than 10% complete before default became imminent, and 44

(3) foreclosure was not regarded as foreseeable at the time the applicable partnership entered into such lease. For as long as any of these hotels constitute foreclosure property, the income from the hotels would be subject to tax at the maximum corporate rates, but it would qualify under the 75% and 95% gross income tests. However, if any of these hotels does not constitute foreclosure property at any time in the future, income earned from the disposition or operation of such property will not qualify under the 75% and 95% gross income tests. "Interest" generally will not qualify under the 75% or 95% gross income tests if it depends in whole or in part on the income or profits of any person. However, interest will not fail to so qualify solely by reason of being based upon a fixed percentage or percentages of receipts or sales. Host Marriott does not expect to derive significant amounts of interest that will not qualify under the 75% and 95% gross income tests. The non-controlled subsidiaries hold various assets, the ownership of which by Host Marriott, L.P. might jeopardize Host Marriott's status as a REIT. These assets primarily consist of partnership or other interests in hotels that are not leased, certain foreign hotels, and approximately $75 million in value of personal property associated with certain Hotels. Host Marriott, L.P. owns 100% of the nonvoting stock of each non-controlled subsidiary but none of the voting stock or control of that non-controlled subsidiary. Each non-controlled subsidiary is taxable as a regular "C" corporation. Host Marriott, L.P.'s share of any dividends received from a non-controlled subsidiary should qualify for purposes of the 95% gross income test, but not for purposes of the 75% gross income test. Host Marriott, L.P. does not anticipate that it will receive sufficient dividends from the non-controlled subsidiaries to cause it to fail the 75% gross income test. Host Marriott inevitably will have some gross income from various sources that fails to constitute qualifying income for purposes of one or both of the 75% or 95% gross income tests. These include, but are not limited to, the following: . "safe harbor" leases, . the lease of the Harbor Beach Resort, which provides for rent based upon net profits, . the operation of the hotel that is located in Sacramento, . minority partnership interests in partnerships that own hotels that are not leased under leases that produce rents qualifying as "rents from real property," and . rent attributable to personal property at a relatively small group of hotels that does not satisfy the 15% personal property test. Host Marriott, however, believes that, even taking into account the anticipated sources of non-qualifying income, its aggregate gross income from all sources will satisfy the 75% and 95% gross income tests applicable to REITs for each taxable year commencing subsequent to the date of the REIT conversion. If Host Marriott fails to satisfy one or both of the 75% or 95% gross income tests for any taxable year, it may nevertheless qualify as a REIT for such year if it is entitled to relief under certain provisions of the Internal Revenue Code. These relief provisions will be generally available if Host Marriott's failure to meet such tests was due to reasonable cause and not due to willful neglect, Host Marriott attaches a schedule of the sources of its income to its federal income tax return and any incorrect information on the schedule was not due to fraud with intent to evade tax. It is not possible, however, to state whether in all circumstances Host Marriott would be entitled to the benefit of these relief provisions. For example, if Host Marriott fails to satisfy the gross income tests because nonqualifying income that Host Marriott intentionally incurs exceeds the limits on such income, the IRS could conclude that Host Marriott's failure to satisfy the tests was not due to reasonable cause. If these relief provisions are inapplicable to a particular set of circumstances involving Host Marriott, Host Marriott will not qualify as a REIT. As discussed above in "--General," even if these relief provisions apply, a tax would be imposed with respect to the excess net income. 45

Any gain realized by Host Marriott on the sale of any property held as inventory or other property held primarily for sale to customers in the ordinary course of business, including Host Marriott's share of any such gain realized by Host Marriott, L.P., will be treated as income from a "prohibited transaction" that is subject to a 100% penalty tax. Such prohibited transaction income may also have an adverse effect upon Host Marriott's ability to satisfy the income tests for qualification as a REIT. Under existing law, whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business is a question of fact that depends upon all the facts and circumstances with respect to the particular transaction. Host Marriott, L.P. intends that both it and its subsidiaries will hold hotels for investment with a view to long-term appreciation, to engage in the business of acquiring and owning hotels and to make such occasional sales of hotels as are consistent with Host Marriott, L.P.'s investment objectives. There can be no assurance, however, that the IRS might not contend that one or more of such sales is subject to the 100% penalty tax. Asset Tests Applicable to REITs. Host Marriott, at the close of each quarter of its taxable year, must satisfy three tests relating to the nature of its assets. First, at least 75% of the value of Host Marriott's total assets must be represented by real estate assets. Host Marriott's real estate assets include, for this purpose, its allocable share of real estate assets held by Host Marriott, L.P. and the non-corporate subsidiaries of Host Marriott, L.P., as well as stock or debt instruments held for less than one year purchased with the proceeds of a stock offering, or long-term (at least five years) debt offering of Host Marriott, cash, cash items and government securities. Second, no more than 25% of Host Marriott's total assets may be represented by securities other than those in the 75% asset class. Third, of the investments included in the 25% asset class, the value of any one issuer's securities owned by Host Marriott may not exceed 5% of the value of Host Marriott's total assets and Host Marriott may not own more than 10% of any one issuer's outstanding voting securities. Host Marriott, L.P. does not own any of the voting stock of any of non- controlled subsidiaries but it does own 100% of the nonvoting stock of each non-controlled subsidiary. Host Marriott, L.P. may also own nonvoting stock, representing substantially all of the equity, in other corporate entities that serve as partners or members in the various entities that hold title to the hotels. Neither Host Marriott, Host Marriott, L.P., nor any of the non- corporate subsidiaries of Host Marriott, L.P., own more than 10% of the voting securities of any entity that is treated as a corporation for federal income tax purposes. In addition, Host Marriott believes that the securities of any one issuer owned by Host Marriott, Host Marriott, L.P., or any of the non- corporate subsidiaries of Host Marriott, L.P., including Host Marriott's pro rata share of the value of the securities of each non-controlled subsidiary do not exceed 5% of the total value of Host Marriott's assets. There can be no assurance, however, that the IRS might not contend that the value of such securities exceeds the 5% value limitation or that nonvoting stock of a non- controlled subsidiary or another corporate entity owned by Host Marriott, L.P. should be considered "voting stock" for this purpose. After initially meeting the asset tests at the close of any quarter, Host Marriott will not lose its status as a REIT for failure to satisfy the asset tests at the end of a later quarter solely by reason of changes in asset values. If the failure to satisfy the asset tests results from an acquisition of securities or other property during a quarter the failure can be cured by disposition of sufficient nonqualifying assets within 30 days after the close of that quarter. An example of such an acquisition would be an increase in Host Marriott's interest in Host Marriott, L.P. as a result of the exercise of a limited partner's unit redemption right or an additional capital contribution of proceeds from an offering of capital stock by Host Marriott. Host Marriott to maintains adequate records of the value of its assets to ensure compliance with the asset tests and to take such other actions within 30 days after the close of any quarter as may be required to cure any noncompliance. If Host Marriott fails to cure noncompliance with the asset tests within such time period, Host Marriott would cease to qualify as a REIT. Clinton Administration's Proposed Changes to REIT Asset Test. The Clinton Administration's fiscal year 1999 budget proposal, announced on February 2, 1998, includes a proposal to amend the 10% voting securities test. The proposal would require a REIT to own no more than 10% of the vote or value of all classes of stock of any corporation (except for qualified REIT subsidiaries or corporations that qualify as REITs). Corporations 46

existing prior to the effective date of the proposal generally would be "grandfathered"; i.e., the REIT would be subject to the existing 10% voting securities test described above with respect to grandfathered corporations. However, such "grandfathered" status would terminate with respect to a corporation if the corporation engaged in a new trade or business or acquired substantially new assets. Because Host Marriott, L.P. owns 100% of the nonvoting stock of each non- controlled subsidiary, and Host Marriott is deemed to own an interest in each non-controlled subsidiary equal to its proportionate interest in Host Marriott, L.P., Host Marriott would not satisfy the proposed 10% value limitation with respect to any of the non-controlled subsidiaries. Whether any of the non- controlled subsidiaries would qualify as a grandfathered corporation as the proposal is currently drafted would depend upon the effective date of the proposal, which is not yet known. If a non-controlled subsidiary otherwise eligible for "grandfathered" status were to engage in a new trade or business or were to acquire substantial new assets, or if Host Marriott were to make a capital contribution to a non-controlled subsidiary otherwise eligible for "grandfathered" status, its "grandfathered" status would terminate and Host Marriott would fail to qualify as a REIT. Moreover, Host Marriott would not be able to own, directly or indirectly, more than 10% of the vote or value of any corporation formed or acquired after the effective date of the proposal. Thus, the proposal, if enacted, would materially impede Host Marriott's ability to engage in new third-party management or similar activities. Annual Distribution Requirements Applicable to REITs. Host Marriott, in order to qualify as a REIT, is required to distribute dividends, other than capital gain dividends, to its stockholders in an amount at least equal to (i) the sum of (a) 95% of REIT taxable income, computed without regard to the dividends paid deduction and Host Marriott's net capital gain, and (b) 95% of the net income, after tax, if any, from foreclosure property, minus (ii) the sum of certain items of noncash income. In addition, if Host Marriott disposes of any built-in gain asset during its Recognition Period, Host Marriott is required, pursuant to Treasury Regulations which have not yet been promulgated, to distribute at least 95% of the built-in gain, after tax, if any, recognized on the disposition of such asset. See "-- General" above for a discussion of built-in gain assets. Such distributions must be paid in the taxable year to which they relate, or in the following taxable year if declared before Host Marriott timely files its tax return for such year and if paid on or before the first regular dividend payment date after such declaration. Host Marriott intends to make timely distributions sufficient to satisfy these annual distribution requirements. In this regard, Host Marriott, L.P.'s partnership agreement authorizes Host Marriott, as general partner, to take such steps as may be necessary to cause Host Marriott, L.P. to distribute to its partners an amount sufficient to permit Host Marriott to meet these distribution requirements. To the extent that Host Marriott does not distribute all of its net capital gain or distributes at least 95%, but less than 100%, of its REIT taxable income, as adjusted, it is subject to tax thereon at regular ordinary and capital gain corporate tax rates. Host Marriott, however, may designate some or all of its retained net capital gain, so that, although the designated amount will not be treated as distributed for purposes of this tax, a stockholder would include its proportionate share of such amount in income, as capital gain, and would be treated as having paid its proportionate share of the tax paid Host Marriott with respect to such amount. The stockholder's basis in its capital stock of Host Marriott would be increased by the amount the stockholder included in income and decreased by the amount of the tax the stockholder is treated as having paid. Host Marriott would make an appropriate adjustment to its earnings and profits. For a more detailed description of the federal income tax consequences to a stockholder of such a designation, see "--Taxation of Taxable U.S. Stockholders Generally." There is a significant possibility that Host Marriott's REIT taxable income will exceed its cash flow, due in part to certain "non-cash" or "phantom" income expected to be taken into account in computing Host Marriott's REIT taxable income. Host Marriott anticipates, however, that it will generally have sufficient cash 47

or liquid assets to enable it to satisfy the distribution requirements described above. It is possible, however, that Host Marriott, from time to time, may not have sufficient cash or other liquid assets to meet these distribution requirements. In such event, in order to meet the distribution requirements, Host Marriott may find it necessary to arrange for short-term, or possibly long-term, borrowings to fund required distributions and/or to pay dividends in the form of taxable stock dividends. Host Marriott calculates its REIT taxable income based upon the conclusion that the non-corporate subsidiaries of Host Marriott, L.P. or Host Marriott, L.P. itself, as applicable, is the owner of the hotels for federal income tax purposes. As a result, Host Marriott expects that the depreciation deductions with respect to the hotels will reduce its REIT taxable income. This conclusion is consistent with the conclusion above that the leases entered into with the Crestline subsidiaries will be treated as true leases for federal income tax purposes. If the IRS were to challenge successfully this position, in addition to failing in all likelihood the 75% and 95% gross income tests described above, Host Marriott also might be deemed retroactively to have failed to meet the REIT distribution requirements and would have to rely on the payment of a "deficiency dividend" in order to retain its REIT status. Under certain circumstances, Host Marriott may be able to rectify a failure to meet the distribution requirement for a year by paying "deficiency dividends" to stockholders in a later year, which may be included in Host Marriott's deduction for dividends paid for the earlier year. Thus, Host Marriott may be able to avoid being taxed on amounts distributed as deficiency dividends; however, Host Marriott would be required to pay interest based upon the amount of any deduction taken for deficiency dividends. Furthermore, if Host Marriott should fail to distribute during each calendar year at least the sum of 85% of its REIT ordinary income for such year, 95% of its REIT capital gain income for such year, and any undistributed taxable income from prior periods, it would be subject to an excise tax. The excise tax would equal 4% of the excess of such required distribution over the sum of amounts actually distributed and amounts retained with respect to which the REIT pays federal income tax. Failure of Host Marriott to Qualify as a REIT. If Host Marriott fails to qualify for taxation as a REIT in any taxable year, and if the relief provisions do not apply, Host Marriott will be subject to tax, including any applicable alternative minimum tax, on its taxable income at regular corporate rates. Distributions to stockholders in any year in which Host Marriott fails to qualify will not be deductible by Host Marriott nor will they be required to be made. As a result, Host Marriott's failure to qualify as a REIT would significantly reduce the cash available for distribution by Host Marriott to its stockholders and could materially reduce the value of its capital stock. In addition, if Host Marriott fails to qualify as a REIT, all distributions to stockholders will be taxable as ordinary income, to the extent of Host Marriott's current and accumulated E&P, although, subject to certain limitations of the Internal Revenue Code, corporate distributees may be eligible for the dividends received deduction with respect to these distributions. Unless entitled to relief under specific statutory provisions, Host Marriott also will be disqualified from taxation as a REIT for the four taxable years following the year during which qualification was lost. It is not possible to state whether in all circumstances Host Marriott would be entitled to such statutory relief. Taxation of Taxable U.S. Stockholders Generally Distributions by Host Marriott. As long as Host Marriott qualifies as a REIT, distributions made by Host Marriott out of its current or accumulated E&P, and not designated as capital gain dividends constitute dividends taxable to its taxable U.S. stockholders as ordinary income. Such distributions are not eligible for the dividends received deduction in the case of U.S. stockholders that are corporations. To the extent that Host Marriott makes distribution not designated as capital gain dividends in excess of its current and accumulated E&P, such distributions are treated first as a tax-free return of capital to each U.S. stockholder, reducing the adjusted basis which such U.S. stockholder has in its common stock for tax purposes by the amount of such distribution but not below zero, with distributions in excess of a U.S. stockholder's adjusted basis in its common stock taxable as capital gains, provided that the common stock has been held as a capital asset. 48

Dividends declared by Host Marriott in October, November or December of any year and payable to a stockholder of record on a specified date in any such month shall be treated as both paid by Host Marriott and received by the stockholder on December 31 of such year, provided that the dividend is actually paid by Host Marriott on or before January 31 of the following year. Distributions made by Host Marriott that are properly designated by Host Marriott as capital gain dividends are taxable to taxable non-corporate U.S. stockholders, i.e., individuals, estates or trusts. They are taxed as gain from the sale or exchange of a capital asset held for more than one year to the extent that they do not exceed Host Marriott's actual net capital gain for the taxable year, without regard to the period for which such non-corporate U.S. stockholder has held his common stock. In the event that Host Marriott designates any portion of a dividend as a "capital gain dividend," a U.S. stockholder's share of such capital gain dividend would be an amount which bears the same ratio to the total amount of dividends paid to such U.S. stockholder for the year as the aggregate amount designated as a capital gain dividend bears to the aggregate amount of all dividends paid on all classes of shares for the year. On November 10, 1997, the IRS issued Notice 97-64, which provides generally that Host Marriott may classify portions of its designated capital gain dividend as either a 20% gain distribution, which would be taxable to non-corporate U.S. stockholders at a maximum rate of 20%, an unrecaptured Section 1250 gain distribution, which would be taxable to non-corporate U.S. stockholders at a maximum rate of 25%, or a 28% rate gain distribution, which would be taxable to non-corporate U.S. stockholders at a maximum rate of 28%. If no designation is made, the entire designated capital gain dividend will be treated as a 28% rate gain distribution. Notice 97-64 provides that a REIT must determine the maximum amounts that it may designate as 20% and 25% rate capital gain dividends by performing the computation required by the Internal Revenue Code as if the REIT were an individual whose ordinary income were subject to a marginal tax rate of at least 28%. Notice 97-64 further provides that designations made by the REIT only will be effective to the extent that they comply with Revenue Ruling 89-81, which requires that distributions made to different classes of shares be composed proportionately of dividends of a particular type. On July 22, 1998, as part of the IRS Restructuring Act, the holding period requirement for the application of the 20% and 25% capital gain tax rates was reduced to 12 months from 18 months for sales of capital gain assets on or after January 1, 1998. Although Notice 97-64 will apply to sales of capital gain assets after July 28, 1997 and before January 1, 1998, it is expected that the IRS will issue clarifying guidance, most likely applying the same principles set forth in Notice 97-64, regarding a REIT's designation of capital gain dividends in light of the new holding period requirements. For a discussion of the capital gain tax rates applicable to non-corporate U.S. stockholders, see "--Taxpayer Relief Act and IRS Restructuring Act Changes to Capital Gain Taxation" below. Distributions made by Host Marriott that are properly designated by Host Marriott as capital gain dividends will be taxable to taxable corporate U.S. stockholders as long-term gain to the extent that they do not exceed Host Marriott's actual net capital gain for the taxable year at a maximum rate of 35% without regard to the period for which such corporate U.S. stockholder has held its common stock. Such U.S. stockholders may, however, be required to treat up to 20% of certain capital gain dividends as ordinary income. U.S. stockholders may not include in their individual income tax returns any net operating losses or capital losses of Host Marriott. Instead, such losses would be carried over by Host Marriott for potential offset against future income, subject to certain limitations. Distributions made by Host Marriott and gain arising from the sale or exchange by a U.S. stockholder of common stock will not be treated as passive activity income, and, as a result, U.S. stockholders generally will not be able to apply any "passive losses" against such income or gain. In addition, taxable distributions from Host Marriott generally will be treated as investment income for purposes of the investment interest limitation. Capital gain dividends and capital gains from the disposition of shares, including distributions treated as such, however, will be treated as investment income only if the U.S. stockholder so elects, in which case such capital gains will be taxed at ordinary income rates. Host Marriott will notify stockholders after the close of its taxable year as to the portions of distributions attributable to that year that constitute ordinary income, return of capital and capital gain. Host Marriott may designate, by written notice to its stockholders, its net capital gain so that with respect to retained net capital 49

gains, a U.S. stockholder would include its proportionate share of such gain in income, as long-term capital gain, and would be treated as having paid its proportionate share of the tax paid by Host Marriott with respect to the gain. The U.S. stockholder's basis in its common stock would be increased by its share of such gain and decreased by its share of such tax. With respect to such long-term capital gain of a U.S. stockholder that is an individual or an estate or trust, the IRS, as described above in this section, has authority to issue regulations that could apply the special tax rate applicable generally to the portion of the long-term capital gains of an individual or an estate or trust attributable to deductions for depreciation taken with respect to depreciable real property. IRS Notice 97-64, described above in this section, did not address the taxation of non-corporate REIT stockholders with respect to retained net capital gains. Sales of Common Stock. Upon any sale or other disposition of common stock, a U.S. stockholder will recognize gain or loss for federal income tax purposes in an amount equal to the difference between (i) the amount of cash and the fair market value of any property received on such sale or other disposition and (ii) the holder's adjusted basis in such common stock for tax purposes. Such gain or loss will be capital gain or loss if the common stock has been held by the U.S. stockholder as a capital asset. In the case of a U.S. stockholder who is an individual or an estate or trust, such gain or loss will be long-term capital gain or loss, and any such long-term capital gain shall be subject to the maximum capital gain rate of 20%. In the case of a U.S. stockholder that is a corporation, such gain or loss will be long-term capital gain or loss if such shares have been held for more than one year, and any such capital gain shall be subject to the maximum capital gain rate of 35%. In general, any loss recognized by a U.S. stockholder upon the sale or other disposition of common stock that has been held for six months or less, after applying certain holding period rules, will be treated as a long-term capital loss, to the extent of distributions received by such U.S. stockholder from Host Marriott that were required to be treated as long-term capital gains. Taxpayer Relief Act and IRS Restructuring Act Changes to Capital Gain Taxation. The Taxpayer Relief Act of 1997 altered the taxation of capital gain income. Under the Act, individuals, trusts and estates that hold certain investments for more than 18 months may be taxed at a maximum long-term capital gain rate of 20% on the sale or exchange of those investments. Individuals, trusts and estates that hold certain assets for more than one year but not more than 18 months may be taxed at a maximum long-term capital gain rate of 28% on the sale or exchange of those investments. The Taxpayer Relief Act also provides a maximum rate of 25% for "unrecaptured Section 1250 gain" for individuals, trusts and estates, special rules for "qualified 5-year gain" and other changes to prior law. The recently enacted IRS Restructuring Act of 1998, however, reduced the holding period requirement established by the Taxpayer Relief Act for the application of the 20% and 25% capital gain tax rates to 12 months from 18 months for sales of capital gain assets after December 31, 1997. The Taxpayer Relief Act allows the IRS to prescribe regulations on how the Taxpayer Relief Act's capital gain rates will apply to sales of capital assets by "pass-through entities," including REITs, such as Host Marriott, and to sales of interests in "pass-through entities." For a discussion of the rules under the Taxpayer Relief Act that apply to the taxation of distributions by Host Marriott to its stockholders that are designated by Host Marriott as "capital gain dividends," see "--Distributions by Host Marriott" above. Stockholders are urged to consult with their own tax advisors with respect to the rules contained in the Taxpayer Relief Act and the IRS Restructuring Act. Backup Withholding for Host Marriott's Distributions Host Marriott reports to its U.S. stockholders and the IRS the amount of dividends paid during each calendar year and the amount of tax withheld, if any. Under the backup withholding rules, a U.S. stockholder may be subject to backup withholding at the rate of 31% with respect to dividends paid unless such holder either is a corporation or comes within certain other exempt categories and, when required, demonstrates this fact, or provides a taxpayer identification number, certifies as to no loss of exemption from backup withholding and otherwise complies with applicable requirements of the backup withholding rules. A U.S. stockholder that does not provide Host Marriott with a correct taxpayer identification number may also be subject to penalties imposed by the IRS. Any amount paid as backup withholding is creditable against the stockholder's income tax liability. In addition, Host Marriott may be required to withhold a portion of its capital gain distributions to any U.S. stockholders who fail to certify their non-foreign status to Host Marriott. See "--Taxation of Non-U.S. Stockholders." 50

Taxation of Tax-Exempt Stockholders Provided that a tax-exempt stockholder has not held its common stock as "debt financed property" within the meaning of the Internal Revenue Code and such common stock are not otherwise used in a trade or business, the dividend income from Host Marriott will not be unrelated business taxable income ("UBTI") to a tax-exempt stockholder. Similarly, income from the sale of common stock will not constitute UBTI unless such tax-exempt stockholder has held such common stock as "debt financed property" within the meaning of the Internal Revenue Code or has used the common stock in a trade or business. However, for a tax-exempt stockholder that is a social club, voluntary employee benefit association, supplemental unemployment benefit trust or qualified group legal services plan exempt from federal income taxation under Internal Revenue Code Sections 501 (c)(7), (c)(9), (c)(17) and (c)(20), respectively, income from an investment in Host Marriott will constitute UBTI unless the organization is properly able to deduct amounts set aside or placed in reserve for certain purposes so as to offset the income generated by its investment in Host Marriott. Such a prospective stockholder should consult its own tax advisors concerning these "set aside" and reserve requirements. Notwithstanding the above, however, the Omnibus Budget Reconciliation Act of 1993 provides that, effective for taxable years beginning in 1994, a portion of the dividends paid by a "pension held REIT" shall be treated as UBTI as to any trust which is described in Section 401(a) of the Internal Revenue Code, is tax-exempt under Section 501(a) of the Internal Revenue Code and holds more than 10%, by value, of the interests in the REIT. Tax-exempt pension funds that are described in Section 401(a) of the Internal Revenue Code are referred to below as "qualified trusts." A REIT is a "pension held REIT" if (i) it would not have qualified as a REIT but for the fact that Section 856(h)(3) of the Internal Revenue Code, added by the 1993 Act, provides that stock owned by qualified trusts shall be treated, for purposes of the "not closely held" requirement, as owned by the beneficiaries of the trust rather than by the trust itself, and (ii) either (a) at least one such qualified trust holds more than 25% by value, of the interests in the REIT, or (b) one or more such qualified trusts, each of which owns more than 10%, by value, of the interests in the REIT, hold in the aggregate more than 50%, by value, of the interests in the REIT. The percentage of any REIT dividend treated as UBTI is equal to the ratio of the UBTI earned by the REIT, treating the REIT as if it were a qualified trust and therefore subject to tax on UBTI, to the total gross income of the REIT. A de minimis exception applies where the percentage is less than 5% for any year. The provisions requiring qualified trusts to treat a portion of REIT distributions as UBTI will not apply if the REIT is able to satisfy the "not closely held" requirement without relying upon the "look-through" exception with respect to qualified trusts. Based on the current estimated ownership of Host Marriott common stock and as a result of certain limitations on transfer and ownership of common stock contained in the Host Marriott Articles of Incorporation, Host Marriott should not be classified as a "pension held REIT." Taxation of Non-U.S. Stockholders The rules governing federal income taxation of the ownership and disposition of common stock by non-U.S. stockholders are complex and no attempt is made herein to provide more than a brief summary of such rules. Accordingly, the discussion does not address all aspects of federal income tax and does not address state, local or foreign tax consequences that may be relevant to a non- U.S. stockholder in light of its particular circumstances. In addition, this discussion is based on current law, which is subject to change, and assumes that Host Marriott qualifies for taxation as a REIT. Prospective non-U.S. stockholders should consult with their own tax advisers to determine the impact of federal, state, local and foreign income tax laws with regard to an investment in common stock, including any reporting requirements. Distributions by Host Marriott. Distributions by Host Marriott to a non-U.S. stockholder that are neither attributable to gain from sales or exchanges by Host Marriott of United States real property interests nor 51

designated by Host Marriott as capital gains dividends will be treated as dividends of ordinary income to the extent that they are made out of current or accumulated E&P of Host Marriott. Such distributions ordinarily will be subject to withholding of United States federal income tax on a gross basis (that is, without allowance of deductions) at a 30% rate or such lower rate as may be specified by an applicable income tax treaty, unless the dividends are treated as effectively connected with the conduct by the non-U.S. stockholder of a United States trade or business. Under certain treaties, however, lower withholding rates generally applicable to dividends do not apply to dividends from a REIT, such as Host Marriott. Certain certification and disclosure requirements must be satisfied to be exempt from withholding under the effectively connected income exemption. Dividends that are effectively connected with such a trade or business will be subject to tax on a net basis (that is, after allowance of deductions) at graduated rates, in the same manner as U.S. stockholders are taxed with respect to such dividends and are generally not subject to withholding. Any such dividends received by a non-U.S. stockholder that is a corporation may also be subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. Host Marriott expects to withhold United States income tax at the rate of 30% on any distribution made to a non-U.S. stockholder unless (i) a lower treaty rate applies and any required form or certification evidencing eligibility for that lower rate is filed with Host Marriott or (ii) a non-U.S. stockholder files an IRS Form 4224 with Host Marriott claiming that the distribution is effectively connected income. Distributions in excess of the current or accumulated E&P of Host Marriott will not be taxable to a non-U.S. stockholder to the extent that they do not exceed the adjusted basis of the stockholder's common stock, but rather will reduce the adjusted basis of such common stock. To the extent that such distributions exceed the adjusted basis of a non-U.S. stockholder's common stock, they will give rise to gain from the sale or exchange of its common stock, the tax treatment of which is described below. As a result of a legislative change made by the Small Business Job Protection Act of 1996, it appears that Host Marriott will be required to withhold 10% of any distribution in excess of its current and accumulated E&P. Consequently, although Host Marriott intends to withhold at a rate of 30%, or a lower applicable treaty rate, on the entire amount of any distribution, to the extent that Host Marriott does not do so, any portion of a distribution not subject to withholding at a rate of 30%, or lower applicable treaty rate, would be subject to withholding at a rate of 10%. However, a non-U.S. stockholder may seek a refund of such amounts from the IRS if it subsequently determined that such distribution was, in fact, in excess of current or accumulated E&P of Host Marriott, and the amount withheld exceeded the non-U.S. stockholder's United States tax liability, if any, with respect to the distribution. Distributions to a non-U.S. stockholder that are designated by Host Marriott at the time of distribution as capital gain dividends, other than those arising from the disposition of a United States real property interest, generally will not be subject to United States federal income taxation, unless: (i) the investment in the common stock is effectively connected with the non-U.S. stockholder's United States trade or business, in which case the non-U.S. stockholder will be subject to the same treatment as U.S. stockholders with respect to such gain, except that a stockholder that is a foreign corporation may also be subject to the 30% branch profits tax, as discussed above, or (ii) the non-U.S. stockholder is a nonresident alien individual who is present in the United States for 183 days or more during the taxable year and has a "tax home" in the United States, in which case the nonresident alien individual will be subject to a 30% tax on the individual's capital gains. Pursuant to the federal law known as FIRPTA, distributions to a non-U.S. stockholder that are attributable to gain from sales or exchanges by Host Marriott of United States real property interests, whether or not designated as capital gain dividends, will cause the non-U.S. stockholder to be treated as recognizing such gain as income effectively connected with a United States trade or business. non-U.S. stockholders would thus generally be taxed at the same rates applicable to U.S. stockholders, subject to a special alternative minimum tax in the case of nonresident alien individuals. Also, such gain may be subject to a 30% branch profits tax in 52

the hands of a non-U.S. stockholder that is a corporation, as discussed above. Host Marriott is required to withhold 35% of any such distribution. That amount is creditable against the non-U.S. stockholder's federal income tax liability. Although the law is not entirely clear on the matter, it appears that amounts designated by Host Marriott pursuant to the Taxpayer Relief Act as undistributed capital gains in respect of the common stock held by U.S. Stockholders (see "--Annual Distribution Requirements Applicable to REITs" above) would be treated with respect to non-U.S. stockholders in the manner outlined in the preceding two paragraphs for actual distributions by Host Marriott of capital gain dividends. Under that approach, the non-U.S. stockholders would be able to offset as a credit against their United States federal income tax liability resulting therefrom their proportionate share of the tax paid by Host Marriott on such undistributed capital gains and to receive from the IRS a refund to the extent their proportionate share of such tax paid by Host Marriott were to exceed their actual United States federal income tax liability. Sales of Common Stock. Gain recognized by a non-U.S. stockholder upon the sale or exchange of common stock generally will not be subject to United States taxation unless such shares constitute a "United States real property interest" within the meaning of FIRPTA. The common stock will not constitute a "United States real property interest" so long as Host Marriott is a "domestically controlled REIT." A "domestically controlled REIT" is a REIT in which at all times during a specified testing period less than 50% in value of its stock is held directly or indirectly by non-U.S. stockholders. Host Marriott believes, but cannot guarantee, that it is a "domestically controlled REIT." Moreover, even if Host Marriott is a "domestically controlled REIT," because the common stock is publicly traded, no assurance can be given that Host Marriott will continue to be a "domestically controlled REIT." Notwithstanding the foregoing, gain from the sale or exchange of common stock not otherwise subject to FIRPTA will be taxable to a non-U.S. stockholder if the non-U.S. stockholder is a nonresident alien individual who is present in the United States for 183 days or more during the taxable year and has a "tax home" in the United States. In such case, the nonresident alien individual will be subject to a 30% United States withholding tax on the amount of such individual's gain. Even if Host Marriott does not qualify as or ceases to be a "domestically controlled REIT," gain arising from the sale or exchange by a non-U.S. stockholder of common stock would not be subject to United States taxation under FIRPTA as a sale of a "United States real property interest" if: (i) the common stock is "regularly traded," as defined by applicable regulations, on an established securities market such as the NYSE, and (ii) such non-U.S. stockholder owned 5% or less of the common stock throughout the five-year period ending on the date of the sale or exchange. If gain on the sale or exchange of common stock were subject to taxation under FIRPTA, the non-U.S. stockholder would be subject to regular United States income tax with respect to such gain in the same manner as a taxable U.S. stockholder (subject to any applicable alternative minimum tax, a special alternative minimum tax in the case of nonresident alien individuals and the possible application of the 30% branch profits tax in the case of foreign corporations) and the purchaser of the common stock would be required to withhold and remit to the IRS 10% of the purchase price. Backup Withholding Tax and Information Reporting. Backup withholding tax generally is a withholding tax imposed at the rate of 31% on certain payments to persons that fail to furnish certain information under the United States information reporting requirements. Backup withholding and information reporting will generally not apply to distributions paid to non-U.S. stockholders outside the United States that are treated as dividends subject to the 30% (or lower treaty rate) withholding tax discussed above, capital gain dividends or distributions attributable to gain from the sale or exchange by Host Marriott of United States real property interests. As a general matter, backup withholding and information reporting will not apply to a payment of the proceeds of a sale of common stock by or through a foreign office of a foreign broker. Generally, information 53

reporting (but not backup withholding) will apply, however, to a payment of the proceeds of a sale of common stock by a foreign office of a broker that: (a) is a United States person, (b) derives 50% or more of its gross income for certain periods from the conduct of a trade or business in the United States, or (c) is a "controlled foreign corporation," which is, generally, a foreign corporation controlled by United States stockholders. If, however, the broker has documentary evidence in its records that the holder is a non-U.S. stockholder and certain other conditions are met or the stockholder otherwise establishes an exemption information reporting will not apply. Payment to or through a United States office of a broker of the proceeds of a sale of common stock is subject to both backup withholding and information reporting unless the stockholder certifies under penalty of perjury that the stockholder is a non-U.S. stockholder, or otherwise establishes an exemption. A non-U.S. stockholder may obtain a refund of any amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the IRS. The IRS has recently finalized regulations regarding the withholding and information reporting rules discussed above. In general, these regulations do not alter the substantive withholding and information reporting requirements but unify certification procedures and forms and clarify and modify reliance standards. These regulations generally are effective for payments made after December 31, 2000, subject to certain transition rules. Valid withholding certificates that are held on December 31, 1999, will remain valid until the earlier of December 31, 2000 or the date of expiration of the certificate under rules currently in effect, unless otherwise invalidated due to changes in the circumstances of the person whose name is on such certificate. A non-U.S. stockholder should consult its own advisor regarding the effect of the new regulations. Tax Aspects of Host Marriott's Ownership of Interests in Host Marriott, L.P. General. Substantially all of Host Marriott's investments are held through Host Marriott, L.P., which will hold the hotels either directly or through certain subsidiaries. In general, partnerships are "pass-through" entities that are not subject to federal income tax. Rather, partners are allocated their proportionate shares of the items of income, gain, loss, deduction and credit of a partnership, and are potentially subject to tax thereon, without regard to whether the partners receive a distribution from the partnership. Host Marriott includes in its income its proportionate share of the foregoing partnership items for purposes of the various REIT income tests and in the computation of its REIT taxable income. Moreover, for purposes of the REIT asset tests, Host Marriott includes its proportionate share of assets held through Host Marriott, L.P. and certain of its subsidiaries. See "--Federal Income Taxation of Host Marriott--Ownership of Partnership Interests by a REIT." Entity Classification. If Host Marriott, L.P. or any non-corporate subsidiary other than a subsidiary held through an entity treated for federal income tax purposes as a corporation were treated as an association, the entity would be taxable as a corporation and therefore would be subject to an entity level tax on its income. In such a situation, the character of Host Marriott's assets and items of gross income would change and could preclude Host Marriott from qualifying as a REIT (see "--Federal Income Taxation of Host Marriott-- Asset Tests Applicable to REITs" and "--Income Tests Applicable to REITs"). The entire discussion of the federal income tax consequences of the ownership of common stock is based on Host Marriott, L.P. and all of its non- corporate subsidiaries, other than a subsidiary held by an entity treated as a corporation for federal income tax purposes, being classified as partnerships for federal income tax purposes. Pursuant to regulations under Section 7701 of the Internal Revenue Code, a partnership will be treated as a partnership for federal income tax purposes unless it elects to be treated as a corporation or would be treated as a corporation because it is a "publicly traded partnership." Neither Host Marriott, L.P. nor any of the non-corporate subsidiaries have elected or will elect to be treated as a corporation, and therefore, subject to 54

the disclosure below, each will be treated as a partnership for federal income tax purposes (or if it has only one partner or member, disregarded entirely for federal income tax purposes). Pursuant to Section 7704 of the Internal Revenue Code, however, a partnership that does not elect to be treated as a corporation nevertheless will be treated as a corporation for federal income tax purposes if it is a "publicly traded partnership," unless at least ninety percent (90%) of its income consists of "qualifying income" within the meaning of that section. A "publicly traded partnership" is any partnership (i) the interests in which are traded on an established securities market or (ii) the interests in which are readily tradable on a "secondary market or the substantial equivalent thereof." Units of limited partnership interest in Host Marriott L.P. will not be traded on an established securities market. There is a significant risk, however, that after the right to redeem such units becomes exercisable, such interests would be considered readily tradable on the substantial equivalent of a secondary market. In this regard, the income requirements generally applicable to REITs and the definition of "qualifying income" under Section 7704 of the Internal Revenue Code are similar in most key respects. There is one significant difference, however, that is relevant to Host Marriott, L.P. For a REIT, rent from a tenant does not qualify as "rents from real property" if the REIT and/or one or more actual or constructive owners of 10% or more of the REIT actually or constructively own 10% or more of the tenant; under Section 7704 of the Internal Revenue Code, rent from a tenant is not qualifying income if a partnership and/or one or more actual or constructive owners of 5% or more of the partnership actually or constructively own 10% or more of the tenant. A substantial majority of Host Marriott, L.P. income comes from rent payments by subsidiaries of Crestline. Accordingly, because The Blackstone Group, Host Marriott and any owner of 10% or more of Host Marriott will own or be deemed to own 5% or more of Host Marriott, L.P., if The Blackstone Group, Host Marriott and/or any owner of 10% or more of Host Marriott were to own or be deemed to own collectively 10% or more of Crestline, none of the rent from the lessees of Host Marriott's hotels would be qualifying income for purposes of determining whether Host Marriott, L.P. should be taxed as a corporation. In order to avoid this result, the Crestline articles of incorporation expressly provide that no person (or persons acting as a group), including The Blackstone Group, Host Marriott and any owner of 10% or more of Host Marriott, may own, actually and/or constructively, more than 9.8% by value of the equity in Crestline and the Crestline articles of incorporation contain self-executing mechanisms intended to enforce this prohibition. In addition, Host Marriott, L.P.'s partnership agreement prohibits any person, or persons acting as a group, or entity, other than an affiliate of The Blackstone Group and Host Marriott, from owning, actually and/or constructively, more than 4.9% of the value of Host Marriott, L.P., and the Host Marriott charter prohibits any person, or persons acting as a group, or entity, including The Blackstone Group and the Marriott family and their affiliated entities as a group, from, subject to certain limited exceptions, owning, actually and/or constructively, more than 9.8% of the lesser of the number or value of the total outstanding shares of Host Marriott. Assuming that all of these prohibitions are enforced at all times in accordance with their terms, then so long as Host Marriott, L.P.'s income is such that Host Marriott could meet the gross income tests applicable to REITs (see "--Federal Income Taxation of Host Marriott--Income Tests Applicable to REITs" and "--Ownership of Partnership Interests by a REIT"), Host Marriott, L.P.'s "qualifying income" should be sufficient for it to avoid being classified as a corporation even if it were considered a publicly traded partnership. If Host Marriott, L.P. were taxable as a corporation, most, if not all, of the tax consequences described herein would be inapplicable. In particular, Host Marriott would not qualify as a REIT because the value of Host Marriott's ownership interest in Host Marriott, L.P. would exceed 5% of Host Marriott's assets and Host Marriott would be considered to hold more than 10% of the voting securities of another corporation (see "--Federal Income Taxation of Host Marriott--Asset Tests Applicable to REITs"), which would adversely affect the value of the common stock (see "--Federal Income Taxation of Host Marriott--Failure of Host Marriott to qualify as a REIT"). Allocations of Operating Partnership Income, Gain, Loss and Deduction. The partnership agreement of the Host Marriott, L.P. provides that if Host Marriott, L.P. operates at a net loss, net losses shall be allocated to 55

Host Marriott and the limited partners in proportion to their respective percentage ownership interests in Host Marriott, L.P., provided that net losses that would have the effect of creating a deficit balance in a limited partner's capital account as specially adjusted for such purpose ("Excess Losses") will be reallocated to Host Marriott, as general partner of Host Marriott, L.P. The partnership agreement also provides that, if Host Marriott, L.P. operates at a net profit, net income shall be allocated first to Host Marriott to the extent of Excess Losses with respect to which Host Marriott has not previously been allocated net income. Any remaining net income shall be allocated in proportion to the respective percentage ownership interests of Host Marriott and the limited partners. Finally, the partnership agreement provides that if Host Marriott, L.P. has preferred units outstanding, income will first be allocated to such preferred units to the extent necessary to reflect and preserve the economic rights associated with such preferred units. Although a partnership agreement will generally determine the allocation of income and loss among partners, such allocations will be disregarded for tax purposes if they do not comply with the provisions of Section 704(b) of the Internal Revenue Code and the applicable regulations. Generally, Section 704(b) and the applicable regulations require that partnership allocations respect the economic arrangement of the partners. If an allocation is not recognized for federal income tax purposes, the item subject to the allocation will be reallocated in accordance with the partners' interests in the partnership, which will be determined by taking into account all of the facts and circumstances relating to the economic arrangement of the partners with respect to such item. The allocations of taxable income and loss provided for in the Host Marriott, L.P. partnership agreement and the partnership agreements and operating agreements of the non-corporate subsidiaries are intended to comply with the requirements of Section 704(b) of the Internal Revenue Code and the regulations promulgated thereunder. Tax Allocations with Respect to the Hotels. Pursuant to Section 704(c) of the Internal Revenue Code, income, gain, loss and deduction attributable to appreciated or depreciated property, such as the hotels, that is contributed to a partnership in exchange for an interest in the partnership must be allocated in a manner such that the contributing partner is charged with, or benefits from, respectively, the difference between the adjusted tax basis and the fair market value of such property at the time of contribution associated with the property at the time of the contribution. This difference is know as built-in gain. The Host Marriott, L.P. partnership agreement requires that such allocations be made in a manner consistent with Section 704(c) of the Internal Revenue Code. In general, the partners of Host Marriott, L.P., including Host Marriott, who contributed depreciated assets having built-in gain are allocated depreciation deductions for tax purposes that are lower than such deductions would be if determined on a pro rata basis. Thus, the carryover basis of the contributed assets in the hands of Host Marriott, L.P. may cause Host Marriott to be allocated lower depreciation and other deductions, and therefore to be effectively allocated more income, which might adversely affect Host Marriott's ability to comply with the REIT distribution requirements. See "--Federal Income Taxation of Host Marriott--Annual Distribution Requirements Applicable to REITs". In addition, in the event of the disposition of any of the contributed assets which have built-in gain, all income attributable to the built-in gain generally will be allocated to the contributing partners, even though the proceeds of such sale would be allocated proportionately among all the partners and likely would be retained by Host Marriott, L.P., rather than distributed. Thus, if Host Marriott, L.P. were to sell a hotel with built-in gain that was contributed to Host Marriott, L.P. by Host Marriott's predecessors or Host Marriott, Host Marriott generally would be allocated all of the income attributable to the built-in gain, which could exceed the economic or book income allocated to it as a result of such sale. Such an allocation might cause Host Marriott to recognize taxable income in excess of cash proceeds, which might adversely affect Host Marriott's ability to comply with the REIT distribution requirements. In addition, Host Marriott will be subject to a corporate level tax on such gain to the extent the gain is recognized within the 10-year period after the first day of Host Marriott's first taxable year as a REIT). See "--Federal Income Taxation of Host Marriott--Annual Distribution Requirements Applicable to REITs" and "--Federal Income Taxation of Host Marriott--General." It should be noted in this regard that as the general partner of Host Marriott, L.P., Host Marriott will determine whether or not to sell a hotel contributed to Host Marriott, L.P. by Host Marriott. 56

Host Marriott, L.P. and Host Marriott generally use the traditional method, with a provision for a curative allocation of gain on sale to the extent prior allocations of depreciation with respect to a specific hotel were limited by the "ceiling rule" applicable under the traditional method, to account for built-in gain with respect to the hotels contributed to Host Marriott, L.P. in connection with the REIT conversion. This method is generally a more favorable method for accounting for built-in gain from the perspective of those partners, including Host Marriott, who received units of limited partnership interest in Host Marriott, L.P. in exchange for property with a low basis relative to value at the time of the REIT conversion and is a less favorable method from the perspective of those partners who contributed cash or "high basis" assets to Host Marriott, L.P., including Host Marriott, to the extent it contributes cash to Host Marriott, L.P. Any property purchased by Host Marriott, L.P. subsequent to the REIT conversion will initially have a tax basis equal to its fair market value, and Section 704(c) of the Internal Revenue Code will not apply. Other Tax Consequences for Host Marriott and Its Stockholders Host Marriott and its stockholders are subject to state or local taxation in various state or local jurisdictions, including those in which Host Marriott, L.P. or they transact business or reside. The state and local tax treatment of Host Marriott and its stockholders may not conform to the federal income tax consequences discussed above. Consequently, prospective stockholders of Host Marriott should consult their own tax advisors regarding the effect of state and local tax laws on an investment in Host Marriott. A portion of the cash to be used by Host Marriott to fund distributions comes from each non-controlled subsidiary through payments of dividends on the shares of such corporation held by Host Marriott, L.P. and, in some cases, interest on notes held by Host Marriott, L.P. Each non-controlled subsidiary pays federal and state income tax at the full applicable corporate rates on its taxable income computed without regard to any deduction for dividends. To the extent that a non-controlled subsidiary is required to pay federal, state or local taxes, the cash otherwise available for distribution by Host Marriott to its stockholders will be reduced accordingly. 57

PLAN OF DISTRIBUTION Host Marriott may sell the offered securities being offered hereby: (i) directly to purchasers; (ii) through agents; (iii) through dealers; (iv) through underwriters; (v) directly to its stockholders; or (vi) through a combination of any such methods of sale. In addition, the offered securities may be issued by Host Marriott as a dividend or distribution. The distribution of the offered securities may be effected from time to time in one or more transactions either: (i) at a fixed price or prices, which may be changed; (ii) at market prices prevailing at the time of sale; (iii) at prices related to such prevailing market prices; or (iv) at negotiated prices. Offers to purchase offered securities may be solicited directly by Host Marriott. Offers to purchase offered securities may also be solicited by agents designated by Host Marriott from time to time. Any such agent, who may be deemed to be an "underwriter" as that term is defined in the Securities Act, involved in the offer or sale of the offered securities in respect of which this prospectus is delivered will be named, and any commissions payable by Host Marriott to such agent will be set forth in the prospectus supplement. If a dealer is utilized in the sale of the offered securities in respect of which this prospectus is delivered, Host Marriott will sell such offered securities to the dealer, as principal. The dealer, who may be deemed to be an "underwriter" as that term is defined in the Securities Act, may then resell such offered securities to the public at varying prices to be determined by such dealer at the time of resale. If an underwriter is, or underwriters are, utilized in the sale, Host Marriott will execute an underwriting agreement with such underwriters at the time of sale to them and the names of the underwriters will be set forth in the prospectus supplement, which will be used by the underwriter to make resales of the offered securities in respect of which this prospectus is delivered to the public. In connection with the sale of offered securities, such underwriter may be deemed to have received compensation from Host Marriott in the form of underwriting discounts or commissions and may also receive commissions from purchasers of offered securities for whom they may act as agents. Underwriters may also sell offered securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. Any underwriting compensation paid by Host Marriott to underwriters in connection with the offering of offered securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers, will be set forth in the applicable prospectus supplement. Pursuant to any standby underwriting agreement entered into in connection with a subscription rights offering to Host Marriott's stockholders, persons acting as standby underwriters may receive a commitment fee for all securities underlying the subscription rights that the underwriter commits to purchase on a standby basis. Additionally, prior to the expiration date with respect to any subscription rights, any standby underwriters in a subscription rights offering to Host Marriott's stockholders may offer such securities on a when-issued basis, including securities to be acquired through the purchase and exercise of subscription rights, at prices set from time to time by the standby underwriters. After the expiration date with respect to such subscription rights, the underwriters may offer securities of the type underlying the subscription rights, whether acquired pursuant to a standby underwriting agreement, the exercise of the subscription rights or the purchase of such securities in the market, to the public at a price or prices to be determined by the underwriters. The standby underwriters may thus realize profits or losses independent of the underwriting discounts or commissions paid by Host Marriott. If Host Marriott does not enter into a standby underwriting arrangement in connection with a subscription rights offering to Host Marriott's stockholders, Host Marriott may elect to retain a dealer-manager to manage such a subscription rights offering for Host Marriott. Any such dealer- manager may offer securities of the type underlying the subscription rights acquired or to be acquired pursuant to the purchase and exercise of subscription rights and may thus realize profits or losses independent of any dealer-manager fee paid by Host Marriott. 58

Underwriters, dealers, agents and other persons may be entitled, under agreements that may be entered into with Host Marriott, to indemnification by Host Marriott against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which they may be required to make in respect thereof. Underwriters and agents may engage in transactions with, or perform services for, Host Marriott in the ordinary course of business. If so indicated in the applicable prospectus supplement, Host Marriott will authorize underwriters, dealers or other persons to solicit offers by certain institutions to purchase offered securities pursuant to contracts providing for payment and delivery on a future date or dates. Institutions with which such contracts may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others. The obligations of any purchasers under any such contract will not be subject to any conditions except that (i) the purchase of the offered securities shall not at the time of delivery be prohibited under the laws of the jurisdiction to which such purchaser is subject, and (ii) if the offered securities are also being sold to underwriters, Host Marriott shall have sold to such underwriters the offered securities not sold for delayed delivery. The underwriters, dealers and such other persons will not have any responsibility in respect of the validity or performance of such contracts. The prospectus supplement relating to such contracts will set forth the price to be paid for offered securities pursuant to such contracts, the commission payable for solicitation of such contracts and the date or dates in the future for delivery of offered securities pursuant to such contracts. Any underwriter may engage in stabilizing and syndicate covering transactions in accordance with Rule 104 under the Exchange Act. Rule 104 permits stabilizing bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. The underwriters may over- allot shares of the offered securities in connection with an offering of offered securities, thereby creating a short position in the underwriters' account. Syndicate covering transactions involve purchases of the offered securities in the open market after the distribution has been completed in order to cover syndicate short positions. Stabilizing and syndicate covering transactions may cause the price of the offered securities to be higher than it would otherwise be in the absence of such transactions. These transactions, if commenced, may be discontinued at any time. The anticipated date of delivery of offered securities will be set forth in the applicable prospectus supplement relating to each offer. LEGAL MATTERS The validity of the offered securities will be passed upon for Host Marriott by Christopher G. Townsend, Esq., Vice President of Host Marriott or by other counsel to Host Marriott. If the offered securities are distributed in an underwritten offering or through agents, certain legal matters may be passed upon for any agents or underwriters by counsel for such agents or underwriters identified in the applicable prospectus supplement. EXPERTS The consolidated financial statements and schedules of Host Marriott, Host Marriott Hotels, Host Marriott, L.P., HMC Senior Communities, Inc., Host Marriott Corporation, a Delaware corporation, and the combined financial statements of HMH Properties, Inc., and subsidiaries and HMC Capital Resources Holding Corporation and subsidiaries and incorporated by reference in this prospectus and elsewhere in the registration statement have been audited by Arthur Andersen LLP, independent public accountants, as indicated in their reports with respect thereto, and are incorporated by reference herein in reliance upon the authority of said firm as experts in giving said reports. 59

Exhibit 1.1 5,200,000 Shares HOST MARRIOTT CORPORATION (a Maryland corporation) 10% Class C Cumulative Redeemable Preferred Stock UNDERWRITING AGREEMENT March 22, 2001

March 22, 2001 Morgan Stanley & Co. Incorporated Bear, Stearns & Co. Inc. Deutsche Banc Alex. Brown Inc. Prudential Securities Incorporated UBS Warburg LLC c/o Morgan Stanley & Co. Incorporated 1585 Broadway New York, New York 10036 Dear Sirs and Mesdames: Host Marriott Corporation, a Maryland corporation (the "Company"), proposes to issue and sell to the several Underwriters named in Schedule I hereto (the "Underwriters") 5,200,000 shares of its 10% Class C Cumulative Redeemable Preferred Stock, par value $.01 per share (the "Firm Shares"). The Company also proposes to issue and sell to the several Underwriters not more than an additional 780,000 shares of its 10% Class C Cumulative Redeemable Preferred Stock, par value $.01 per share (the "Additional Shares"), if and to the extent that you, as Managers of the offering, shall have determined to exercise, on behalf of the Underwriters, the right to purchase such shares of preferred stock granted to the Underwriters in Section 2 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the "Shares", and the Company's 10% Class C Cumulative Redeemable Preferred Stock, par value $.01 per share, is hereinafter sometimes referred to as the "Class C Preferred Stock". The terms of the Shares will be set forth in articles supplementary (the "Articles Supplementary") to be filed by the Company with the Maryland State Department of Assessments and Taxation (the "SDAT"). The Company intends to contribute or otherwise transfer the net proceeds from the sale of the Shares to Host Marriott, L.P., a Delaware limited partnership (the "Operating Partnership"), in exchange for Class C Preferred Units (the "Preferred Units") in the Operating Partnership, the economic terms of which will be substantially identical to those of the Class C Preferred Stock. The terms of the Units will be set forth in one or more amendments (individually, an "Amendment" and, collectively, the "Amendments") to the Operating Partnership's limited partnership agreement, and the Company, in its capacity as general partner of the Operating Partnership (the "General Partner"), will enter into an Amendment each time that the Company issues Shares. The Company will list the Shares on the New York Stock Exchange (the "NYSE"). The Company has filed with the Securities and Exchange Commission (the "Commission") a registration statement on Form S-3 (Registration No. 333-67907), including a prospectus, relating to, among other things, the Shares. The registration statement as amended at the time it became effective, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A under the Securities Act of 1933, as amended (the "Securities Act"), and the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act at the

time of such effectiveness, is hereinafter referred to as the "Registration Statement"; and the related prospectus dated December 30, 1998 (the "Base Prospectus") and prospectus supplement relating to the Shares (the "Prospectus Supplement"), each in the form first used to confirm sales of Shares, together with the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act at the date of the Prospectus Supplement, are hereinafter referred to, collectively, as the "Prospectus". If the Company has filed an abbreviated registration statement to register additional shares of Class C Preferred Stock pursuant to Rule 462(b) under the Securities Act (the "Rule 462 Registration Statement"), then any reference herein to the term "Registration Statement" shall be deemed to include such Rule 462 Registration Statement.

(g) The Underwriters shall have received on the Closing Date an opinion of Brown & Wood LLP, counsel for the Underwriters, dated the Closing Date, with respect to validity of the Shares, with respect to the Registration Statement and the Prospectus and any amendments or supplements thereto, with respect to the matters set forth in the immediately succeeding paragraph, with respect to the authorization, execution and delivery of this Agreement, and with respect to such other matters you may reasonably request, and such counsel shall have received such documents and information as they may reasonably request to enable them to pass upon such matters. In addition to the opinions set forth above in Sections 5(c) and 5(d), respectively, David Reichmann and Latham & Watkins will each also state that such counsel has participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants for the Company, and representatives of the Underwriters, at which the contents of the Registration Statement and the Prospectus and related matters were discussed and, although such counsel may state that such counsel is not passing upon, and does not assume any responsibility for the accuracy, completeness or fairness of, the statements contained or incorporated by reference in the Registration Statement and the Prospectus and such counsel has not made any independent check or verification thereof (except as set forth in Section 5(c)(viii) and 5(d)(iv), respectively), during the course of such participation, no facts came to such counsel's attention that have caused such counsel to believe that the Registration Statement, at the time it became effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or that the Prospectus, as of its date or as of the date of such opinion, contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided 17

that such counsel may state that they express no belief with respect to the financial statements, schedules and other financial and statistical data included or incorporated by reference in or omitted from the Registration Statement or the Prospectus. The opinions of David Reichmann, Latham & Watkins, Hogan & Hartson, L.L.P. and Ballard Spahr Andrews & Ingersoll, LLP described in Sections 5(c), 5(d), 5(e) and 5(f) above shall be rendered to the Underwriters at the request of the Company and the Operating Partnership and shall so state therein and shall further state, solely in the case of those opinions of counsel which refer to subsidiaries of the Company, that all references in such opinions to "subsidiaries" of the Company include, without limitation, the Operating Partnership and the Non-Controlled Subsidiaries. In addition, the opinion of David Reichmann shall state that it covers matters arising under the laws of the State of Maryland, the general corporation law of the State of Delaware (the "DGCL"), the Partnership Act, the Delaware Limited Liability Company Act and the federal laws of the United States, and shall further state that, to the extent that the opinion set forth in Section 5(c)(vi) relates to any instrument or agreement which is governed by the laws of any jurisdiction other than the State of Maryland, such counsel has assumed that the laws of such other jurisdiction are in all relevant respects identical to the laws of the State of Maryland; the opinion of Latham & Watkins shall state that it covers matters arising under the laws of the State of New York, the Partnership Act and the federal laws of the United States, and shall further state that, in rendering the opinion set forth in Section 5(d)(iv) (which may be set forth in a separate legal opinion), such counsel has relied upon and assumed the accuracy of the opinion of Hogan & Hartson L.L.P. delivered pursuant to Section 5(e) of this Agreement; the opinion of Hogan & Hartson, L.L.P. shall state that it covers matters arising under the federal laws of the United States and that Latham & Watkins, in rendering their legal opinion pursuant to Section 5(d)(iv) of this Agreement, may rely upon such opinion; and the opinion of Ballard Spahr Andrews & Ingersoll, LLP shall state that it covers matters arising under the laws of the State of Maryland and shall further state that Latham & Watkins and Brown & Wood llp may rely upon such opinion as if it were addressed to them for the purpose of delivering their opinions pursuant to this Agreement. (h) The Company shall have duly filed the Articles Supplementary with the SDAT prior to the Closing Date and you shall have received evidence of such filing satisfactory to you; the Underwriters shall have received on the Closing Date a copy of an Amendment duly executed by the General Partner; and, concurrently with the issuance and sale of the Shares to the Underwriters, the Operating Partnership shall have issued and sold to the Company Preferred Units with an aggregate liquidation preference equal to the aggregate liquidation preference of such Shares. (i) The Underwriters shall have received, on each of the date hereof and on the Closing Date, a letter dated the date hereof or the Closing Date, as the case may be, in form and substance satisfactory to the Underwriters, from Arthur Andersen llp, independent public accountants, containing statements and information of the type ordinarily included in accountants' "comfort letters" to underwriters with respect to the financial statements of the Company, CCHP I Corporation, CCHP II Corporation, CCHP III Corporation, CCHP IV Corporation and of the Blackstone properties and certain 18

financial information contained and incorporated by reference in the Registration Statement and the Prospectus; provided that the letter delivered on the Closing Date shall use a "cut-off date" not earlier than the date hereof. (j) The Shares have been duly authorized for listing on the NYSE, subject to official notice of issuance. The several obligations of the Underwriters to purchase Additional Shares hereunder are subject to the delivery to you on the Option Closing Date of such documents as you may reasonably request with respect to the good standing of the Company and the Operating Partnership, the due authorization and issuance of the Additional Shares and other matters related to the issuance of the Additional Shares (including, without limitation, updated legal opinions, comfort letters and officers' certificates). 6. Covenants of the Company and the Operating Partnership. In further consideration of the agreements of the Underwriters herein contained, the Company and the Operating Partnership jointly and severally covenant with each Underwriter as follows: (a) To furnish to you, without charge, six signed copies of the Registration Statement, including exhibits thereto and documents incorporated or deemed to be incorporated by reference therein, and for delivery to each other Underwriter a conformed copy of the Registration Statement, without exhibits thereto but including documents incorporated or deemed to be incorporated by reference therein, and to furnish to you in New York City, without charge, prior to 10:00 a.m. New York City time on the business day next succeeding the date of this Agreement and during the period mentioned in Section 6(c) below, as many copies of the Prospectus and any supplements and amendments thereto or to the Registration Statement as you may reasonably request. (b) Before amending or supplementing the Registration Statement or the Prospectus, to furnish to you a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which you reasonably object, and to file with the Commission within the applicable period specified in Rule 424(b) under the Securities Act any prospectus required to be filed pursuant to such Rule. (c) If, during such period after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriters the Prospectus is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses you will furnish to the Company) to which Shares may have been sold by you on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented 19

will not, in the light of the circumstances when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with law. (d) To endeavor to qualify the Shares for offer and sale under the securities or Blue Sky laws of such jurisdictions as you shall reasonably request. (e) To make generally available to the Company's security holders and to you as soon as practicable an earning statement covering the twelve- month period ending on the last day of the first fiscal quarter of the Company's 2002 fiscal year, which earning statement satisfies the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder. (f) Contemporaneously with each issuance of Shares hereunder, the Company, in its capacity as General Partner, will enter into an appropriate Amendment and the Company will contribute the net proceeds from the sale of such Shares to the Operating Partnership, and, in exchange for the contribution of such net proceeds, the Operating Partnership will issue to the Company Preferred Units with an aggregate liquidation preference equal to the aggregate liquidation preference of such Shares, and the terms of such Preferred Units will be substantially equivalent to the economic terms of such Shares purchased by the Underwriters. The Operating Partnership will apply such net proceeds as set forth under the caption "Use of Proceeds" in the Prospectus Supplement. (g) To use their best efforts to effect the listing of the Shares on the NYSE no later than March 27, 2001. (h) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, to pay or cause to be paid all expenses incident to the performance of their respective obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company's and the Operating Partnership's respective counsel and accountants in connection with the registration and delivery of the Shares under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Prospectus and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or Legal Investment memorandum in connection with the offer and sale of the Shares under state securities laws and all expenses in connection with the qualification of the Shares for offer and sale under state securities laws as provided in Section 6(d) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky or Legal Investment memorandum, (iv) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification, if any, of the offering of the Shares by the National Association 20

of Securities Dealers, Inc., (v) all fees and expenses in connection with the preparation and filing of the registration statement on Form 8-A relating to the Shares and all costs and expenses incident to listing the Shares on the NYSE, (vi) the cost of printing certificates representing the Shares, (vii) the costs and charges of any transfer agent, registrar or depositary, (viii) the costs and expenses of the Company and the Operating Partnership relating to investor presentations on any "road show" undertaken in connection with the marketing of the offering of the Shares, including, without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Company, travel and lodging expenses of the representatives and officers of the Company and the Operating Partnership and any such consultants, and the cost of any aircraft chartered in connection with the road show, and (ix) all other costs and expenses incident to the performance of the obligations of the Company and the Operating Partnership hereunder for which provision is not otherwise made in this Section. Without limitation to the provisions of the immediately preceding sentence, the Company will, within 24 hours after request by the Representatives, pay expenses incurred by the Underwriters in connection with this Agreement and the offering of the Shares in an amount not to exceed $370,000, such payment to be made by wire transfer of immediately available funds; provided that any expenses payable by the Company pursuant to the immediately preceding sentence shall be excluded in determining the dollar amount of expenses payable by the Company under this sentence; and provided, further, that no payment shall be required by the Company pursuant to this sentence unless the Underwriters shall have purchased the Firm Shares. It is understood, however, that except as provided in this Section, Section 7 entitled "Indemnity and Contribution", and the last paragraph of Section 9 below, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, stock transfer taxes payable on resale of any of the Shares by them and any advertising expenses connected with any offers they may make. 7. Indemnity and Contribution. (a) The Company and the Operating Partnership jointly and severally agree to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment to the Registration Statement, any preliminary prospectus or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through you expressly for use therein; provided, however, that the -------- ------- foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, 21

damages or liabilities purchased Shares, or any person controlling such Underwriter, if a copy of the Prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto but excluding documents incorporated or deemed to be incorporated by reference therein) was not sent or given by or on behalf of such Underwriter to such person, if required by law so to have been delivered, at or prior to the written confirmation of the sale of the Shares to such person, and if the Prospectus (as so amended or supplemented) would have cured the defect giving rise to such losses, claims, damages or liabilities, unless such failure is the result of noncompliance by the Company with Section 6(a) hereof. (b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement, the Operating Partnership and each person, if any, who controls the Company or the Operating Partnership within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company and the Operating Partnership to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through you expressly for use in the Registration Statement, any preliminary prospectus, the Prospectus or any amendments or supplements thereto. (c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 7(a) or 7(b), such person (the "indemnified party") shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by Morgan Stanley & Co. Incorporated, in the case of parties indemnified pursuant to Section 7(a), and by the Company, in the case of parties indemnified pursuant to Section 7(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is 22

entered into more than 60 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. The obligations and agreements of the Company and the Operating Partnership under this Section 7(c) are joint and several. (d) To the extent the indemnification provided for in Section 7(a) or 7(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Operating Partnership on the one hand and the Underwriters on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 7(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 7(d)(i) above but also the relative fault of the Company and the Operating Partnership on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Operating Partnership on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company and the Operating Partnership on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Operating Partnership or by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The obligations of the Company and the Operating Partnership to contribute pursuant to this Section 7 are joint and several. The Underwriters' respective obligations to contribute pursuant to this Section 7 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. (e) The Company, the Operating Partnership and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any 23

such action or claim. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity. (f) The indemnity and contribution provisions contained in this Section 7 and the representations, warranties and other statements of the Company and the Operating Partnership contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Company, its officers or directors or any person controlling the Company or by or on behalf of the Operating Partnership, its partners or any person controlling the Operating Partnership and (iii) acceptance of and payment for any of the Shares. If any indemnified party shall suffer or incur any losses, claims, damages or liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in any Prior Registration Statement (as defined below) or any amendment thereto in connection with the offering of the Shares or any of the other matters contemplated by this Agreement, or if any proceeding (including any governmental investigation) shall be instituted involving an indemnified party based thereon or in connection therewith, then all references to the Registration Statement and any amendments or supplements thereto contained in this Section 7 and in the representations and warranties of the Company and the Operating Partnership in this Agreement and all references to the effective date of the Registration Statement shall also be deemed to refer, respectively, to such Prior Registration Statement (including the documents incorporated or deemed to be incorporated by reference therein pursuant to Item 12 of Form S-3) and any amendments or supplements thereto and to the effective date of such Prior Registration Statement, mutatis mutandis. As used in this Agreement, the term "Prior Registration Statement" means any registration statement (other than the Registration Statement) filed by the Company or Host Marriott Corporation, a Delaware corporation, with the Commission. 8. Termination. This Agreement shall be subject to termination by notice given by you to the Company, if (a) after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the National Association of Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in your judgment, is material and adverse and (b) in the case of any of the events specified in clauses 8(a)(i) through 8(a)(iv), such event, singly or together with any other such event, makes it, in 24

your judgment, impracticable to market the Shares on the terms and in the manner contemplated in the Prospectus. 9. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto. If, on the Closing Date or the Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 9 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased, and arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non- defaulting Underwriter or the Company. In any such case either you or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected.

EXHIBIT 5.1 [DR LETTERHEAD] March 23, 2001 Host Marriott Corporation 10400 Fernwood Road Bethesda, Maryland 20817 Re: 10% Class C Cumulative Redeemable Preferred Stock ------------------------------------------------- Ladies and Gentlemen: In connection with the offering of up to 5,980,000 shares of 10% Class C Cumulative Redeemable Preferred Stock of the Company, par value $.01 per share (the "Shares"), pursuant to an effective registration statement on Form S-3 filed with the Securities and Exchange Commission (the "Commission") (File No. 333-67907) (the "Registration Statement"), under the Securities Act of 1933, as amended (the "Act"), by Host Marriott Corporation, a Maryland corporation (the "Company"), you have requested my opinion with respect to the matters set forth below. In my capacity as your counsel in connection with this offering, I am familiar with the proceedings taken and proposed to be taken by the Company in connection with the authorization, issuance and sale of the Shares. In addition, I have made such legal and factual examinations and inquiries, including an examination of originals or copies certified or otherwise identified to my satisfaction of such documents, corporate records and instruments, as I have deemed necessary or appropriate for purposes of this opinion. In my examination, I have assumed the genuineness of all signatures, the authenticity of all documents submitted to me as originals, and the conformity to authentic original documents of all documents submitted to me as copies. I am opining herein as to the effect on the subject transaction only of the General Corporation Law of the State of Maryland, and I express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or as to any matters of municipal law or the laws of any local agencies within any state. Subject to the foregoing, it is my opinion that the Shares have been duly authorized, and, upon issuance, delivery and payment therefor in the manner contemplated by the Registration Statement, will be validly issued, fully paid and nonassessable.
