         THIS SUBORDINATION OF MANAGEMENT AGREEMENT (this "AGREEMENT") is made
as of November 25, 1998, by and among THE WASHINGTON CORPORATION, a Maryland
corporation ("MANAGER"), and ARLINGTON SQUARE LIMITED PARTNERSHIP, a Virginia
limited partnership ("OWNER"), for the benefit of METROPOLITAN LIFE INSURANCE
COMPANY, a New York corporation (together with its successors and assigns as
the lender in respect of the Loan referred to below, "LENDER").

                                    RECITALS

         A. Owner owns certain real property described on EXHIBIT A attached
hereto (the "PROPERTY"). Manager and Owner or Owner's predecessor-in-interest

hereto as EXHIBIT B (such Management Agreement, together with any amendments,
supplements or other modifications thereto as described on EXHIBIT B, the
"MANAGEMENT AGREEMENT"). The Management Agreement describes Manager's and
Owner's respective rights and obligations regarding the management and leasing
of the Property.

         B. Lender has made or is about to make a loan (the "LOAN") in the
principal amount of $21,500,000.00 to Owner. In connection with the Loan, Owner
has executed and delivered, or expects to execute and deliver, to Lender (i) a
Promissory Note in the original principal amount of $21,500,000.00 (as the same
may be amended, restated, supplemented or otherwise modified from time to time,
the "NOTE"), (ii) a first priority Deed of Trust, Security Agreement and Fixture
Filing (as the same may be amended, restated, supplemented or otherwise modified
from time to time, the "DEED OF TRUST") and (iii) the other Loan Documents (as
defined in the Deed of Trust). All capitalized terms used herein without
definition shall have the respective meanings ascribed to them in the Deed of
Trust.

         C. At Owner's request and in order to facilitate Lender's agreement to
make the Loan to Owner, Manager and Owner desire to subordinate the Management
Agreement, their respective rights under the Management Agreement and their
respective interests in the Property, if any, to the Deed of Trust and the Loan
upon the terms and conditions contained in this Agreement.

         D. Manager and Owner intend that the Secured Indebtedness evidenced by
the Note and the lien and security interests of the Deed of Trust and the Loan
Documents be paramount and prior to any and all obligations, expenses and
indebtedness owing to Manager which arise from the Management Agreement and any
and all existing liens or future rights to liens of Manager or any person or
entity claiming by, through or under Manager which arise from any and all
obligations, expenses and indebtedness owing to Manager under or in connection
with the Management Agreement.

         NOW THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which Manager and Owner acknowledge, Manager and Owner agree for
the benefit of Lender as follows:


<PAGE>


          1. Manager and Owner hereby unconditionally subordinate and subject
the Management Agreement and all of their respective rights under the Management
Agreement, including, without limitation, any right to receive any amounts as
management fees, leasing commissions or other compensation, to the lien of the
Deed of Trust and Lender's rights and all remedies under the Loan Documents,
including, without limitation, Lender's right to receive payments of principal,
interest and all other sums due and owing from time to time under the Loan
Documents. Manager and Owner agree that the rights of Lender under the Deed of
Trust and the other Loan Documents are senior and prior to any rights of Manager
and Owner under the Management Agreement. Manager and Owner agree that they will
not, without the express written consent of Lender, modify, amend, cancel,
terminate or extend the Management Agreement.

          2. Manager and Owner certify and acknowledge to Lender as follows: (a)
Lender would not make and fund the Loan without the execution and delivery of
this Agreement; (b) a true and complete copy of the Management Agreement
(including, without limitation, all modifications and amendments thereto, if
any) is attached to this Agreement as EXHIBIT B; (c) the Management Agreement
represents the entire agreement between Manager and Owner with respect to the
Property; (d) as of the date hereof, management fees (including reimbursement
for Manager's costs) payable to Manager under the Management Agreement are being
paid on a current basis; (e) Manager has no existing defenses or claims against
Owner with respect to the Management Agreement; and (f) as of the date hereof,
to the best knowledge of Manager and Owner, the Management Agreement is in full
force and effect, and no event of default on the part of either party
thereunder, or any event or condition that, with the giving of notice or the
passage of time, or both, would constitute an event of default on the part of
either party thereunder, has occurred and is continuing.

          3. Manager and Owner agree that if Lender or any assignee or
transferee of Lender acquires title to the Property through judicial or
nonjudicial foreclosure or otherwise, Lender and/or any such assignee or
transferee following such acquisition of title, may, in its sole discretion,
terminate. the Management Agreement by written notice delivered to Manager, and
Lender shall have no obligations or liability to Manager on account thereof.

          4. If Lender or any designee or affiliate of Lender shall acquire
possession of the Property through judicial or nonjudicial foreclosure or
otherwise, Lender or such designee or affiliate shall have the right to cause
Manager to continue its management of the Property by assuming the
obligations of Owner under the Management Agreement, but (a) without any
liability for any act or omission of Owner prior to the date of acquisition,
(b) without being subject to any offsets or advances which Manager may have
had against Owner, and (c) without being bound by any agreement or
modification of the Management Agreement entered into without Lender's
consent. If Lender or any designee or affiliate of Lender assumes the
obligations of Owner under the Management Agreement pursuant to this Section,
and if Lender or such designee or affiliate shall thereafter desire to sell
the Property to a third party, then Lender shall either (i) cause such third
party to assume the obligations of Owner under the Management Agreement or
(ii) terminate the Management Agreement by written notice to Manager without
further obligation thereunder. If a third party shall acquire title to the
Property as a purchaser at a foreclosure sale or otherwise in connection with
the exercise of any remedies

                                       2

<PAGE>


of Lender under the Loan Documents, then such third party, immediately upon
acquiring title to the Property, shall have the right to cause Manager to
continue its management of the Property by assuming the obligations of Owner
under the Management Agreement, but subject to the conditions set forth in
clauses (a) through (c) of this Section. Following any assumption by Lender or
any designee or affiliate of Lender or any such third party, in accordance with
the terms and conditions of this Section, of the obligations of Owner under the
Management Agreement, Manager shall recognize such person or entity as the Owner
under the Management Agreement.

         5. Manager agrees that Lender and its successors and assigns shall not
have any liability under the Management Agreement until such time, if any, as
Lender or such successor or assign, as applicable, shall have assumed the
obligations of Owner under the Management Agreement and, in any event, Manager
shall look only to the estate and property of Lender or its successors or
assigns in the Property for the satisfaction of Manager's remedies for the
collection of a judgment (or other judicial process) requiring the payment of
money in the event of any default by Lender or its successors or assigns under
the Management Agreement, and no other property or assets of Lender or its
successors or assigns shall be subject to levy, execution or other enforcement
procedure for the satisfaction of Manager's remedies under or with respect to
the Management Agreement or the relationship of the parties thereunder.

         6. Any notice, demand, statement, request or consent made hereunder
