                  NOW, THEREFORE, in consideration of the premises and the

                  1.   Amendments to Section 1.  Section 1 of the Rights
                       -----------------------
Agreement is amended as follows:

                  (A) The text of paragraph (k) thereof is deleted in its
entirety and replaced by the phrase "[Intentionally Omitted.]";

                  (B) The text of paragraph (p) thereof is deleted in its
entirety and replaced by the following:

                        "(p) "Exempt Shares" shall mean, as to any Person, (i)
                  shares of Common Stock beneficially owned (without giving
                  effect to the last sentence of Section 1(e)) by such Person
                  that have been received by such Person pursuant to the
                  Agreement and Plan of Merger dated as of November 23, 1998, by
                  and among the Company, Host Marriott Corporation and Host
                  Marriott L.P. (the "Merger Agreement"), in exchange for shares
                  of common stock, par value $1.00 per share of Host Marriott
                  Corporation ("HM Common Stock"), which such Person
                  beneficially owned on February 3, 1989, and owned continuously
                  thereafter until the Merger (as such term is defined in the
                  Merger Agreement), (ii) shares of Common Stock which were
                  acquired by such Person pursuant to a gift, bequest,
                  inheritance or distribution from a trust or from a corporation




                  controlled by such Person, where such shares of
                  Common Stock were Exempt Shares immediately prior to such
                  acquisition and where such shares of Common Stock were
                  beneficially owned (without giving effect to the last sentence
                  of Section 1(e)) by such Person continuously after such
                  acquisition, (iii) shares of Common Stock acquired by such
                  Person as a result of a stock dividend, stock distribution or
                  other recapitalization, in respect to Exempt Shares only,
                  whereby any Common Stock received by such Person is
                  substantially proportional to the amount of Common Stock owned
                  by such Person prior to such transaction and where such Common
                  Stock is beneficially owned (without giving effect to the last
                  sentence of Section 1(e)) by such Person continuously
                  thereafter, and (iv) shares of Common Stock acquired by such
                  Person as a result of such Person becoming a Beneficial Owner
                  (without giving effect to the last sentence of Section 1(e))
                  pursuant solely to clauses (ii) or (iii) of Section 1(e) by
                  any other Person. For purposes of determining whether any
                  shares of Common Stock are Exempt Shares pursuant to clauses
                  (i), (ii), (iii) or (iv) of this Section 1(p), any share of HM
                  Common Stock that was held in "street" or "nominee" name at
                  the effective time of the Merger (as such term is defined in
                  the Merger Agreement) shall be presumed to have been acquired
                  by the beneficial owner subsequent to February 3, 1989. This
                  presumption shall be rebuttable upon presentation to the
                  Company of satisfactory evidence that such share of HM Common
                  Stock has had the same beneficial owner (without giving effect
                  to the last sentence of Section 1(e)) on and continuously
                  after February 3, 1989 until the Merger. Any disputes arising
                  pursuant to this definition shall be definitively resolved by
                  the Board, in its sole discretion."

                  (C) The text of paragraph (q) thereof is deleted in its
entirety and replaced by the phrase "[Intentionally Omitted.]";

                  (D) The text of paragraph  (t) thereof is deleted in its

this Amendment, shall be construed to give to any Person other than the Company,
the Rights Agent and the registered holders of the Rights Certificates (and,

by this Amendment; but the Rights Agreement, as amended by this Amendment, shall
be for the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Rights Certificates (and, prior to the Distribution
Date, registered holders of the Common Stock).
