Item 5:  Other Events
- ---------------------

          On December 30, 1998, Host Marriott Corporation, a Maryland
corporation, announced that it completed the final steps in its conversion to a
real estate investment trust ("REIT") and that it is now positioned to elect
REIT status effective January 1, 1999.

          Host Marriott has consolidated the ownership of all of its assets into
Host Marriott, L.P., a Delaware limited partnership (the "Operating
Partnership"), and its subsidiaries, through which Host Marriott will conduct
its business in the future.  Host Marriott is the sole general partner of the
Operating Partnership. Host Marriott and various other parties own Operating
Partnership units ("OP Units") which represent limited partnership positions
that are exchangeable at various times in the future for shares of Host Marriott
Common Stock on a one-for-one basis or their cash equivalent, at Host Marriott's
election.

          In addition, on December 30, 1998, Host Marriott acquired ownership
of, or controlling interests in, twelve upscale and luxury full-service hotels
and certain other assets from the Blackstone Group and a series of funds
controlled by Blackstone Real Estate Partners.  In exchange for these hotel
properties and other assets, which have an estimated transaction value of
approximately $1.5 billion, the Operating Partnership issued approximately 44
million OP Units, assumed debt and made cash payments totaling approximately
$900 million and transferred 1.4 million shares of Crestline Capital Corporation
(NYSE:CLJ), a former subsidiary of Host Marriott engaged in the hotel leasing,
senior living and asset management businesses.  Host Marriott expects to issue
the Blackstone entities approximately 3.7 million additional OP Units in April
1999 to compensate Blackstone for the Crestline distribution, although the exact
number of OP Units cannot yet be determined.  The Blackstone portfolio includes
the Ritz-Carlton, Amelia Island, the Ritz-Carlton, Boston, the Hyatt Regency
Burlingame at San Francisco Airport, the Hyatt Regency Cambridge, the Hyatt
Regency Reston, Virginia, the Grand Hyatt Atlanta, the Four Seasons
Philadelphia, the Four Seasons Atlanta, the Drake (Swissotel), New York, the
Swissotel Chicago, the Swissotel Boston and the Swissotel Atlanta.  As part of
the transaction, the Operating Partnership also acquired certain other assets,
including the first mortgage loan on the Four Seasons Beverly Hills.  A 25%
interest in the Swissotel U.S. management company also was acquired and
immediately sold to Crestline.

          Host Marriott also announced that the Operating Partnership acquired
eleven affiliated limited partnerships (or controlling interests therein),
including the acquisition of eight public limited partnerships, that own 26 
full-service Marriott hotels. These partnerships were acquired in exchange for
OP Units, representing new equity of approximately $340 million. The exact
number of OP Units to be issued to former limited partners in the eight public
partnerships will not be determined until January 29, 1999 when the pricing
period ends and the former limited partners have elected, no

                                      -2-

 
later than January 22, 1999, whether to retain their OP Units or exchange them
for Host Marriott stock or Operating Partnership notes. The price per OP Unit
will be between $9.50 and $15.50. The eight public partnerships and their final
valuations are as follows:

The Company also announced that it completed acquisitions and restructurings of other partnerships (or controlling interests therein) to enable Host Marriott to complete all of the significant transactions comprising the REIT conversion. These acquisition transactions follow the recent completion of several other steps in connection with Host Marriott's efforts to complete its REIT conversion by year end. On December 18th, Host Marriott's Board of Directors declared a special dividend, payable on or about January 27, 1999, in either $1.00 of cash or .087 share of Host Marriott stock per share of Host Marriott stock owned, at the election of each Host Marriott stockholder of record on December 28, 1998. Based on the cash amount, the implied value of the Host REIT stock in the special dividend is $11.50 per share. Election forms are being mailed to stockholders by year end. On December 29, 1998, Host Marriott completed its reincorporation from Delaware to Maryland through its merger into a wholly owned subsidiary which changed its name to Host Marriott Corporation. Host Marriott also completed the previously announced spinoff of Crestline Capital Corporation (NYSE:CLJ), a former subsidiary. Each Host Marriott stockholder of record on December 28, 1998 received one Crestline share for every ten shares of Host Marriott stock owned. Crestline owns one of the premier portfolios of senior living assets and will lease virtually all of Host Marriott's hotels. The special dividend and the Crestline distribution are taxable dividends. -4- Certain factors that should be considered in deciding whether to invest in securities of Host Marriott Corporation are set forth under the caption "Risk Factors" attached hereto as Exhibit 99.1 and incorporated herein by reference.

                                  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 REITs 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, a separate publicly traded company. These subsidiaries, 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 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.
 
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.
 
                                       2

 
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.
 
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.
 
                                       3

 
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.
 
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
 
                                       4

 
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.
 
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.
 
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. 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
 
                                       5

 
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 FUNDS FROM OPERATIONS 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 funds from operations and cash distributions
would likely adversely affect the market price of our publicly traded
securities.
 
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,
 
                                       6

 
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
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
 
                                       7

 
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
   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
 
                                       8

 
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.
 
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.
 
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 our
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
 
                                       9

 
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. 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 recent
distribution of Crestline common stock.
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.
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.
 
                                       10

 
  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 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. 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.
 
                                       11

 
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.
 
  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.
