LEASING NO. 1, INC., a Delaware corporation (the "Assignor"), and HPT CW
PROPERTIES TRUST, a Maryland real estate investment trust (the "Assignee").

                              W I T N E S S E T H :

        WHEREAS, pursuant to an Second Amended and Restated Lease Agreement,
dated as of the date hereof (as amended from time to time, the "Second Amended
and Restated Lease"), the Assignee has leased to the Assignor and the Assignor
has leased from the Assignee certain premises as more particularly described in
and subject to and upon the terms and conditions set forth in the Second Amended
and Restated Lease; and

        WHEREAS, as security for the payment and performance of each and every
obligation and liability of the Assignor to the Assignee under the Second
Amended and Restated Lease (collectively, the "Obligations"), including, without
limitation, the payment of the Rent (this and other capitalized terms used and
not otherwise defined herein having the meanings ascribed to such terms in the
Second Amended and Restated Lease), the Assignor has agreed to grant to the
Assignee a first and perfected lien and security interest in the Account (as
hereinafter defined);

        NOW, THEREFORE, in consideration of the mutual covenants herein
contained and for other good and valuable consideration, the mutual receipt and
legal sufficiency of which are hereby acknowledged, the Assignor hereby agrees
with the Assignee as follows:

        1. Subject to the terms and conditions hereinafter set forth, the
Assignor hereby assigns, transfers, pledges, conveys and grants to the Assignee,
as security for the payment and performance of the Obligations, all of the
right, title and interest of the Assignor in and to State Street Bank and Trust
Company, Account No. 941-459-2 (the "Account"), all certificates of deposit,
commercial paper, United States Treasury bills, stocks, bonds and other

renewals thereof and all proceeds of the foregoing (collectively, the
"Collateral").

        2. The Assignor agrees promptly to execute and deliver all documents and
instruments deemed necessary by the Assignee to perfect the Assignee's security
interest in the Collateral and, in the event that the Assignor fails to execute
and deliver any such documents and instruments, the Assignor hereby authorizes
the Assignee to execute and deliver the same in the name of the Assignor
pursuant to the power of attorney granted to the Assignee in Paragraph 6 below.

        3. Upon the occurrence and during the continuance of an Event of Default
(as defined in the Second Amended and Restated Lease), the Assignee, without
further authorization, may authorize State Street Bank and Trust Company (the
"Investment Manager") to distribute the Collateral to the Assignee (properly
endorsed or assigned to the Assignee), sell, assign, negotiate or otherwise
dispose of the Collateral and may apply all principal, interest and other
proceeds received by the Assignee from time to time with respect to the
Collateral in reduction of the Obligations. Any balance of the Collateral
remaining after such application until payment in full of the Obligations, shall
be and remain the Collateral hereunder.

        4. To the extent permitted by law, the Assignor hereby waives any notice
of sale or other disposition of all or any part of the Collateral and the
exercise of any other right or remedy of the Assignee existing after the
occurrence and during the continuance of any Event of Default, and, to the
extent any such notice is required and cannot be waived, the Assignor agrees
that if such notice is given in the manner and to the address or addresses then
required pursuant to this Assignment at least five (5) Business Days (as defined
in the Second Amended and Restated Lease) before the time of the sale or other
disposition, such notice shall be deemed reasonable and shall fully satisfy any
legal requirements for the giving of said notice.

        5. The Assignor represents that the Account is the only account in which
deposits of the FF&E Reserve will be made and that, as of the date hereof, the
balance in the Account is ______________________ Dollars ($___________).

        6. Upon the occurrence and during the continuance of an Event of
Default, the Assignor hereby appoints the Assignee as the Assignor's true and
lawful attorney-in-fact to execute all documents and instruments and take all
actions, in the Assignor's name or otherwise, as the Assignee shall deem
necessary or expedient, to cause the Collateral and the proceeds thereof to be
received by the Assignee and to be made available to the Assignee for the
purposes herein specified. The power of attorney hereby granted includes,
without limitation, the right to endorse, in the Assignor's name, to the order
of the Assignee, all checks received by the Assignee as proceeds of the

all documents and instruments necessary to transfer the Collateral to the
Assignee and to apply the funds received upon the negotiation of such checks or
the sale of any of the Collateral as set forth herein. The power of attorney
contained herein is irrevocable and is coupled with an interest and it shall
terminate upon the payment in full of the Obligations.

        7. To the extent permitted by law, the Assignor hereby indemnifies the
Assignee and holds the Assignee harmless from and against all losses, costs,
damages, fees and expenses whatsoever with respect to the exercise of the
foregoing power of attorney and the exercise of the other rights and privileges
granted to the Assignee hereunder, including, without limitation, the right to
use, possess or dispose of the Collateral by the Assignee in accordance with the
terms of this Assignment. The failure or omission of the Assignee's to do any of
the things or exercise any of the rights, interests, powers and authorities

powers and authorities.

privilege herein granted and shall not be responsible for failure to do any or
all of the things for which rights, interests, power and authority are hereby
conveyed. The Assignee shall be responsible only for the application of such
cash or other property as the Assignee shall actually receive pursuant to the
terms hereof. The failure or omission of the Assignee to do any of the things or
exercise any of the rights, interests, powers and authorities herein shall not
be construed to be a waiver of any of such rights, interests, powers and
authorities.
