                               ------------   

          WHEREAS, the Company and the Rights Agent are party to a Rights
Agreement, dated as of November 23, 1998 (the "Rights Agreement");
                                               ----------------   

          WHEREAS, the Company and the Rights Agent desire to amend the Rights

          WHEREAS, for purposes of this Amendment, capitalized terms not
otherwise defined herein shall have the respective meanings set forth in the

          NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

          1.  Certain Definitions.  Section 1 of the Rights Agreement is amended
              -------------------                                               
by adding the following sentence at the end of subsection 1(a) thereof:

          "Notwithstanding anything contained in this Section 1(a), Southeastern
          Asset Management, Inc. ("Southeastern"), an investment advisor
          registered under Section 203 of the Investment Advisers Act of 1940,
          shall not be deemed an "Acquiring Person" until such time (if ever) as
          it becomes the Beneficial Owner of 20% or more of the outstanding
          Common Stock as a result of being or becoming the Beneficial Owner of
          a number of shares of Common Stock in excess of the sum (the "Maximum
          Number") of (i) 40,923,400 shares of Common Stock and (ii) such number
          of shares of Common Stock actually acquired by Southeastern through
          accounts over which it exercises investment discretion, voting
          authority or both as the result of any election (or deemed election)
          to receive Common Stock in payment of the Special Dividend (or, prior
          to the date of any such election or deemed election, such number of
          shares of Common Stock which it can elect to receive in payment of the
          Special Dividend) declared by Host Marriott Corporation on December
          18, 1998 to stockholders of record on December 28, 1998 (as the number
          representing the sum of (i) and (ii) may be adjusted to give effect to
          stock splits, stock dividends, subdivisions, combinations,

 
          reclassifications or similar events, to the extent appropriate), which
          dividend payment obligations will be assumed by the Company in
          connection with the merger of Host Marriott Corporation with and into
          the Company; provided, however, that if at any time after December 28,
                       --------  -------                                        
          1998, the percentage of Common Stock beneficially owned by
          Southeastern is less than 20% of the outstanding Common Stock,
          Southeastern shall be an Acquiring Person if Southeastern shall become
          at any time thereafter the Beneficial Owner of 20% or more of the
          Common Stock then outstanding; provided further, however, that if
                                         -------- -------  -------         
          Southeastern's beneficial ownership of Common Stock is reduced to less
          than 20% as a result of dispositions of Common Stock in the ordinary
          course of trading for its clients' accounts within a five (5)
          consecutive trading day period, and Southeastern reacquires the
          beneficial ownership of the number of shares so disposed, again in the
          ordinary course of trading for its clients' accounts, within twenty
          (20) consecutive trading days immediately after such five (5) day
          trading period, then such reacquisition (subject always to the Maximum
          Number) shall not be deemed to have triggered the 20% threshold.
          Nothing herein is intended to grant, or shall be construed as
          granting, to Southeastern, any of its affiliates or any of
          Southeastern's funds or accounts a waiver from the ownership limit (or
          any provision thereof) under the Charter of the Company."


          2.  Benefits.  Nothing in the Rights Agreement, as amended by 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, prior
to the Distribution Date, the registered holders of the Common Stock) any legal
or equitable right, remedy or claim under the Rights Agreement, as amended 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).

          3.  Descriptive Headings.  Descriptive headings of the several
              --------------------

control or affect the meaning or construction of any of the provisions hereof.

          4.  Governing Law.  This Amendment shall be deemed to be a contract
              -------------                                                  
made under the laws of the State of Maryland and for all purposes shall be
governed by and construed in accordance with the laws of such State.

              ---------------------                                           
Amendment, shall remain and continue in full force and effect and is in all
respects agreed to, ratified and confirmed hereby.  Any reference to the Rights
Agreement after the date first set forth above shall be deemed to be a reference
to the Rights Agreement, as amended by this Amendment.

                                      -2-

 
          6.  Counterparts.  This Amendment may be executed in any number of
              ------------                                                  
counterparts.  It shall not be necessary that the signature of or on behalf of
each party appears on each counterpart, but it shall be sufficient that the
signature of or on behalf of each party appears on one or more of the
counterparts.  All counterparts shall collectively constitute a single
agreement.  It shall not be necessary in any proof of this Amendment to produce
or account for more than a number of counterparts containing the respective
signatures of or on behalf of all of the parties.

          IN WITNESS WHEREOF, the parties hereto have caused this Amendment to
be duly executed and attested, all as of the day and year first above written.
