ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE

     On December 29, 1998, HMC Merger Corporation ("new Host Marriott" and the
"Registrant), a Maryland corporation and formerly a wholly owned subsidiary of
Host Marriott Corporation, a Delaware corporation ("old Host Marriott"),
completed its merger with old Host Marriott as part of old Host Marriott's plan
to convert to a real estate investment trust.  In connection with the merger,
new Host Marriott, as the surviving corporation in the merger, changed its name
from HMC Merger Corporation to Host Marriott Corporation, and commencing at the
opening of trading on December 30, 1998, shares of the new Host Marriott are
being traded on the New York Stock Exchange under the symbol "HMT," the same
symbol under which old Host Marriott was traded prior to the merger.

     New Host Marriott hereby incorporates by reference into this Registration
Statement the following documents filed by it with the Commission:

        (a)    The Registrant's Prospectus dated November 23, 1998 declared

ITEM 4.  DESCRIPTION OF SECURITIES

         A description of the Registrant's Common Stock is incorporated by
reference under Item 3.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL

         Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         The Registrant's Amended and Restated Articles of Incorporation (the
"Articles of Incorporation") and bylaws (the "Bylaws") obligate the Registrant,
to the maximum extent permitted by Maryland law, to indemnify and to pay or
reimburse reasonable expenses in advance of final disposition of a proceeding to
(a) any present or former director or officer who is made party to the
proceeding by reason of his service in that capacity or (b) any individual who,
while a director or officer of the Registrant and at the request of the
Registrant, serves or has served another corporation, real estate investment
trust, partnership, joint venture, trust, employee benefit plan or other
enterprise as a director, trustee, officer or partner of such corporation, real
estate investment trust, partnership, joint venture, trust, employment benefit
plan or other enterprise and who is made a party to the proceeding by reason of
his service in that capacity, against any claim or liability to which he may
become subject by reason of such status. The Registrant's Articles of
Incorporation and Bylaws also permit the Registrant to indemnify and advance
expenses to any person who served a predecessor of the Registrant in any of the
capacities described above and to any employee or agent of the Registrant or a
predecessor of the Registrant. The Registrant's Bylaws require the Registrant to
indemnify a director or officer who has been successful, on the merits or
otherwise, in the defense of any proceeding to which he is made a party by
reason of his service in that capacity. The Maryland General Corporation Law, as
amended (the "MGCL"), permits a Maryland corporation to indemnify and advance
expenses to its directors, officers, employees and agents, and permits a
corporation to indemnify its present and former directors and officers, among
others, against judgments, penalties, fines, settlements and reasonable expenses
actually incurred by them in connection with any proceeding to which they may be
made a party by reason of their service in those or other capacities unless it
is established that (a) the act or omission of the director or officer was
material to the matter giving rise to the proceeding and (i) was committed in
bad faith or (ii) was the result of active and deliberate dishonesty, (b) the
director or officer actually received an improper personal benefit in money,
property or services or (c) in the case of any criminal proceeding, the director
or officer had reasonable cause to believe that the act or omission was
unlawful. However, under the MGCL, a Maryland corporation may not indemnify a
director or officer in a suit by or in the right of the corporation if such
director or officer has been adjudged to be liable to the corporation. In
accordance with the MGCL, the Registrant's Bylaws require it, as a condition to
advancing expenses, to obtain (1) a written affirmation by the director or
officer of his good faith belief that he has met the standard of conduct
necessary for indemnification by the Registrant as authorized by the
Registrant's Bylaws and (2) a written statement by or on his behalf to repay the
amount paid or reimbursed by the Registrant if it shall ultimately be determined
that the standard of conduct was not met.

     The Registrant intends to enter into indemnification agreements with each
of its directors and officers.  The indemnification agreements will require,
among other things, that the Registrant indemnify its directors and officers to
the fullest extent permitted by law and advance to its directors and officers
all related expenses, subject to reimbursement if it is subsequently determined
that indemnification is not permitted.

     The Second Amended and Restated Agreement of Limited Partnership of Host
Marriott, L.P. (the "Partnership Agreement"), of which the Registrant is the
General Partner, also provides for indemnification of the Registrant and its
officers and directors to the same extent that indemnification is provided to
officers and directors of the


 
Registrant in its Articles of Incorporation, and limits the liability of the
Registrant and its officers and directors to Host Marriott, L.P. and its
respective partners to the same extent that the liability of the officers and
directors of the Registrant to the Registrant and its stockholders is limited
under the Registrant's Articles of Incorporation.

     The directors and officers of the Registrant are insured under policies of
insurance maintained by the Registrant, subject to the limits of the policies,
against certain losses arising from any claim made against them by reason of
being or having been such directors and officers, including with respect to
security law claims.

ITEM 9.  UNDERTAKINGS
- ------               

         (a) The undersigned Registrant hereby undertakes:

             (1)  To file, during any period in which offers or sales are being
                  made, a post-effective amendment to this Registration
                  Statement:

                  (i)  To include any prospectus required by Section 10(a)(3) of
                       the Securities Act;

                  (ii) To reflect in the prospectus any facts or events arising
                       after the effective date of this Registration Statement
                       (or the most recent post-effective amendment thereof)
                       which, individually or in the aggregate, represent a
                       fundamental change in the information set forth in this
                       Registration Statement. Notwithstanding the foregoing,
                       any increase or decrease in volume of securities offered
                       (if the total dollar value of securities offered would
                       not exceed that which was registered) and any deviation
                       from the low or high end of the estimated maximum
                       offering range may be reflected in the form of prospectus
                       filed with the Commission pursuant to Rule 424(b) if, in
                       the aggregate, the changes in volume and price represent
                       no more than a 20 percent change in the 

 
                       maximum aggregate offering price set forth in the
                       "Calculation of Registration Fee" table in the effective
                       registration statement; and

               (iii)   To include any material information with respect to the
                       plan of distribution not previously disclosed in the
                       Registration Statement or any material change to such
                       information in the Registration Statement;

               provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do
               not apply if the registration statement is on Form S-3, Form S-8
               or Form F-3, and the information required to be included in a
               post-effective amendment by those paragraphs is contained in the
               periodic reports filed by the Registrant pursuant to Section 13
               or Section 15(d) of the Exchange Act that are incorporated by
               reference in the Registration Statement.

          (2)  That, for the purpose of determining any liability under the
               Securities Act, each such post-effective amendment shall be
               deemed to be a new registration statement relating to the
               securities offered therein, and the offering of such securities
               at that time shall be deemed to be the initial bona fide offering
               thereof.

          (3)  To remove from registration by means of a post-effective
               amendment any of the securities being registered which remain
               unsold at the termination of the offering.

     (b)  The undersigned Registrant hereby further undertakes that, for the
          purposes of determining any liability under the Securities Act, each
          filing of the Registrant's annual report pursuant to Section 13(a) or
          Section 15(d) of the Exchange Act (and, where applicable, each filing
          of an employee benefit plan's annual report pursuant to Section 15(d)
          of the Exchange Act) that is incorporated by reference in the
          Registration Statement shall be deemed to be a new registration
          statement relating to the securities offered herein, and the offering
          of such securities at that time shall be deemed to be the initial bona
          fide offering thereof.

     (c)  Insofar as indemnification for liabilities arising under the
          Securities Act may be permitted to directors, officers and controlling
          persons of the Registrant pursuant to existing provisions or
          arrangements whereby the Registrant may indemnify a director, officer
          or controlling person of the Registrant against liabilities arising
          under the Securities Act, or otherwise, the Registrant has been
          advised that in the opinion of the Securities and Exchange Commission
          such indemnification is against public policy as expressed in the
          Securities Act and is, therefore, unenforceable.  In the event that a
          claim for indemnification against such liabilities (other than the
          payment by the Registrant of expenses incurred or paid by a director,
          officer or controlling person of the Registrant in the successful
          defense of any action, suit or proceeding) is asserted by such
          director, officer or controlling person in connection with the
          securities being registered, the Registrant will, unless in the
          opinion of its counsel the matter has been settled by controlling
          precedent, submit to a court of appropriate jurisdiction the question
          whether such indemnification by it is against public policy as
          expressed in the Securities Act and will be governed by the final
          adjudication of such issue.

 
                              SIGNATURES


     Pursuant to the requirements of the Securities Act, the Registrant
certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in Bethesda, Maryland, on this 25th day of March, 1999.
