Townsend, Senior Vice President and General Counsel of the Company, to the effect that: (i) the Company is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or in good standing would not have a material adverse effect on the Company and its subsidiaries, taken as a whole; (ii) each Subject Subsidiary (as defined below) has been duly organized, is validly existing as a corporation, limited or general partnership or limited liability company, as the case may be, in good standing under the laws of the jurisdiction of its organization, has the power and authority to own and lease its property and to conduct its business as described in the Prospectus and is duly qualified to transact business and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property requires such qualification, except to the extent that the failure to be so qualified or in good standing would not have a material adverse effect on the Company and its subsidiaries, taken as a whole.

In passing upon compliance as to form of such documents, such counsel may assume that the statements made and incorporated by reference therein are correct and complete. (d) The Underwriters shall have received on the Closing Date an opinion of Latham & Watkins, counsel for the Company and the Operating Partnership, dated the Closing Date, to the effect that: (i) the Operating Partnership is a limited partnership duly formed and validly existing under and by virtue of the Partnership Act and, based solely upon certificates of public officials, is in good standing under the laws of the State of Delaware and has the partnership power and authority to own and lease its property and to conduct its business as described in the Prospectus; (ii) the Preferred Units have been duly authorized by the Operating Partnership and, when issued by the Operating Partnership to the Company, will represent valid limited partnership interests in the Operating Partnership; (iii) the execution and delivery by the Company and the Operating Partnership of this Agreement, the offering, issuance and sale of the Shares and the application of the net proceeds therefrom by the Company as contemplated by this Agreement, and the issuance and sale of the Preferred Units by the Operating Partnership to the Company as contemplated by this Agreement, will not (A) violate any provision of the limited partnership agreement or certificate of limited partnership of the Operating Partnership, (B) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any Senior Note Document; or (C) violate any federal law, statute, rule or regulation applicable to the Company or the Operating Partnership or the Partnership Act; and no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required under federal law or the Partnership Act for the offering, issuance or sale of the Shares or the application of the net proceeds therefrom by the Company as contemplated by this Agreement or for the issuance and sale of the Preferred Units by the Operating 13

Such opinion will define the term "Leases" as all real estate leases on the hotels in which the Operating Partnership has a direct or, through a Subsidiary Partnership, indirect interest and pursuant to which the Operating Partnership or a Subsidiary Partnership, as lessor or sublessor, leases a hotel to a lessee or sublessee, respectively, and shall state that such term includes, without limitation, the lease of the Marriott Harbor Beach Resort from Lauderdale Beach Association to Marriott Hotel Services, Inc. (the "Harbor Beach Resort Lease"); and will define the term "Subsidiary Partnership" as each partnership, limited liability company or other entity treated as a partnership for federal income tax purposes 14

(v) Based upon, and subject to, and limited by the assumptions and qualifications set forth in such opinion, such counsel confirms their opinions described in the Base Prospectus under the caption "Federal Income Tax Considerations", as such opinions were set forth in their opinion letter to the Company dated December 29, 1998 that was filed with the Securities and Exchange Commission as an exhibit to the Registration Statement. (f) The Underwriters shall have received on the Closing Date an opinion of Ballard Spahr Andrews & Ingersoll, LLP, special Maryland counsel to the Company, to the effect that: (i) the Company has been duly incorporated and is validly existing under the laws of the State of Maryland and is in good standing with the SDAT; and the Company has the corporate power to own, lease and operate its current properties and to conduct its business as described in the Prospectus under the heading "The Company" and to enter into and perform its obligations under this Agreement; (ii) the authorized stock of the Company conforms in all material respects to the description thereof contained in the Prospectus; (iii) the Shares have been duly authorized by all necessary corporate action on the part of the Company for issuance and sale to the Underwriters pursuant to this Agreement and, when issued and delivered by the Company pursuant to this Agreement against payment of the consideration set forth herein, will be validly issued, fully paid and non-assessable; and the issuance of the Shares is not subject to preemptive rights arising by operation of the laws of the State of Maryland or under the charter or bylaws of the Company; (iv) the form of certificate used to represent the Shares complies in all material respects with the applicable requirements of the laws of the State of Maryland and the charter and bylaws of the Company; (v) the execution and delivery by the Company of, and the performance by the Company of its obligations under, this Agreement (including the issuance and sale of the Shares to the Underwriters) do not result in any 15

violation of the provisions of the charter or by-laws of the Company or, so far as is known to us, any applicable provision of any Maryland law, statute, administrative regulation or administrative or court decree applicable to the Company; (vi) no consent, approval, authorization or order of, or qualification with, any Maryland state governmental authority or agency (other than may be required under Maryland securities or blue sky laws) is required in connection with the authorization, execution or delivery of this Agreement or the Articles Supplementary or for the offering, issuance or sale of the Shares as contemplated by this Agreement, or the application by the Company of the net proceeds from the sale of the Shares as described in the Prospectus under the caption "Use of Proceeds", except for the filing of the Articles Supplementary with, and the acceptance thereof for record by, the SDAT (which filing has been made with and accepted for record by the SDAT in accordance with the MGCL); (vii) We have reviewed the information (A) in the Prospectus Supplement under the caption "Description of the Class A Preferred Stock", (B) in the base prospectus under the captions "Risk Factors-- We Have Adopted Maryland Law Limitations on Changes in Control", "Risk Factors--Maryland Control Share Acquisition Law Could Delay or Prevent a Change in Control", "Description of Common Stock", "Restrictions on Ownership and Transfer" and, to the extent not superceded by the discussion under "Description of the Class A Preferred Stock" in the Prospectus Supplement, "Description of Preferred Stock", and (C) in the 1998 10-K under the captions "Forward-Looking Statements--We have adopted Maryland law limitation on changes in control" and "Forward- Looking Statements--Maryland control share acquisition law could delay or prevent a change in control", and in each case to the extent such information constitutes matters of Maryland law, summaries of Maryland legal matters, summaries of certain provisions of the Company's charter or by-laws, the Articles Supplementary, the Shares or other instruments or agreements governed by Maryland law, or legal conclusions with respect to matters of Maryland law, such information is correct in all material respects. (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, Christopher G. Townsend 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 16

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)(vii) 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 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 Christopher G. Townsend, 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 Christopher G. Townsend 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 other jurisdiction, 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 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 as if it were addressed to them; 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, in rendering their legal opinions pursuant to this Agreement, may rely upon such opinion as if it were addressed to them as to all matters arising under or governed by the laws of the State of Maryland. (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 17

satisfactory to you; 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 and of the Blackstone properties and certain 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. 18

(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 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 third fiscal quarter of the Company's 2000 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 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. (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, 19

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 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 $285,000, 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 20

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, 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 21

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 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. 22

(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 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 23

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 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. If, on the Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase Additional Shares or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement. If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company or the Operating Partnership to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company or 24

the Operating Partnership shall be unable to perform its obligations under this Agreement, the Company and the Operating Partnership will, jointly and severally, reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder. 10. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. 11. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York. 12. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement. 25

EXHIBIT 5.1 [CGT LETTERHEAD] August 2, 1999 Host Marriott Corporation 10400 Fernwood Road Bethesda, Maryland 20817 Re: 10% Class A Cumulative Redeemable Preferred Stock ------------------------------------------------- Ladies and Gentlemen: In connection with the offering of up to 4,600,000 shares of 10% Class A 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 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.

Host Marriott Corporation August 2, 1999 Page 2 I consent to your filing this opinion as an exhibit to Form 8-K and to the reference to me contained under the heading "Legal Matters" in the Prospectus Supplement, dated July 27, 1999.
