                             THIRTIETH AMENDMENT TO
                           SECOND AMENDED AND RESTATED
                        AGREEMENT OF LIMITED PARTNERSHIP
                                       OF
                               HOST MARRIOTT, L.P.


                  THIS THIRTIETH AMENDMENT TO THE SECOND AMENDED AND RESTATED
AGREEMENT OF LIMITED PARTNERSHIP OF HOST MARRIOTT, L.P. (this "Thirtieth
Amendment"), dated as of February ___, 2002, but effective for all purposes as
of December 31, 2001, is entered into by Host Marriott Corporation, a Maryland
corporation, as general partner (the "General Partner") of Host Marriott, L.P.,
a Delaware limited partnership (the "Partnership"), for itself and on behalf of
the limited partners of the Partnership (the "Limited Partners").

                               W I T N E S S E T H
                               - - - - - - - - - -

         WHEREAS, the General Partner issued shares of its common stock ("Common
Stock") pursuant to the exercise of outstanding stock options awarded under the
1997 Host Marriott Corporation and Host Marriott, L.P. Comprehensive Stock and
Cash Incentive Plan, as amended (the "Incentive Plan")* in the amounts of 6,252
(on various dates between October 1, 2001 and October 31, 2001, inclusive),
1,195 (on various dates between November 1, 2001 and November 30, 2001,
inclusive), and 10,280 (on various dates between December 1, 2001 and December
31, 2001, inclusive), and the General Partner acquired a corresponding number of
units of limited partnership interest ("Class A Units") in connection with such
issuances;



--------
* In connection with the formation of the Partnership and the contribution by
the General Partner of substantially all of its assets to the Partnership, the
Partnership agreed to assume and perform all of the obligations of the General
Partner to issue shares of Common Stock pursuant to existing outstanding
options, warrants and other similar rights (including, without limitation, the
conversion rights pursuant to the outstanding QUIPs and the corresponding
conversion rights with respect to the QUIPs Debenture and the issuance of shares
of Common Stock pursuant to the terms of the Incentive Plan) (the "Host Stock
Rights"). All of the shares of Common Stock issued in connection with the Host
Stock Rights are issued by the General Partner for the account of the
Partnership, with the Partnership in turn issuing to the General Partner a
corresponding number of Class A Units. For federal income tax purposes, the
Partnership shall be treated as having purchased the shares of Common Stock from
the General Partner for cash in an amount equal to the fair market value
thereof, with the General Partner then being considered to have paid such cash
to the Partnership as an additional capital contribution in exchange for a
corresponding number of Class A Units. In the event that a recipient of shares
of Common Stock in connection with the Host Stock Rights is required to
recognize compensation income for federal income tax purposes, such compensation
income shall be deemed to have been paid to such recipient of shares of Common
Stock by the Partnership (and not by the General Partner), and the Partnership
shall take into account in computing its taxable income any deduction that may
arise by reason of the holder's recognition of such compensation income.

         WHEREAS, pursuant to restricted stock agreements under which shares of
restricted stock of the General Partner ("Host Restricted Shares") were issued

employees agreed to reinvest any cash dividends received on such Host Restricted
Shares in shares of Common Stock;

         WHEREAS, on October 12, 2001, the General Partner paid a cash dividend

September 28, 2001, and, on or about October 12, 2001, 36,351 shares of Common
Stock were issued in connection with the reinvestment of such cash dividends by

corresponding number of Class A Units in connection with such issuance;

         WHEREAS, on various dates between October 1, 2001 and December 31,
2001, the Limited Partners named on Annex A who were former limited partners of
the partnerships involved in the Partnership Rollup, pursuant to their Unit
Redemption Right, redeemed an aggregate of 62,426 Class A Units of the

Class A Units in connection with that certain Contribution Agreement, dated

Redemption Right, redeemed an aggregate of 437,648 Class A Units of the
Partnership, and the General Partner issued to such Limited Partners an equal
number of shares of Common Stock in exchange for such Class A Units, which Class
