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


          WHEREAS, Borrower, Lender and Escrow Agent are parties to that
certain Reserve Escrow Agreement dated January 1, 1991 which agreement was
entered into as consideration for Lender agreeing to the terms of that
certain Second Mortgage Modification and Consolidation Agreement of even
date therewith recorded with the Suffolk County Registry of Deeds as 
Instrument No. 308 and filed with the Suffolk County Registry District of 
the Land Court as Document No. 482106;

          WHEREAS, Borrower has requested that Lender agree to modify the
terms under which Available Cash flow is required to remain in the Reserve
Account.  All capitalized terms not otherwise defined herein shall have the
meaning ascribed thereto in either the Reserve Escrow Agreement or the
Second Mortgage Modification and Consolidation Agreement; and

          WHEREAS, Lender is willing to accede to Borrower's request
solely upon the terms set forth in this Agreement;

          NOW, THEREFORE, IN CONSIDERATION OF THE MORTGAGED PREMISES, the
parties hereto do hereby covenant and agree as follows:

          1.    Notwithstanding the requirement that Available Cash Flow
be deposited quarterly under the Reserve Escrow Agreement, Available Cash
flow shall be actually determined on a calendar year basis and to the
extent Escrow Agent determines that the amount ("Excess Deposits")
deposited quarterly as Available Cash Flow would not have been deposited if
calculations under the Reserve Escrow Agreement had been made on an annual
basis, Escrow Agent shall remit such Excess Deposit to Borrower.  In making
such determinations, the following provisions shall control:

                a.   Only quarterly deposits made for a particular
calendar year on account of Available Cash Flow shall be used for making
such determination and in no event can money deposited in the Reserve
Account for a preceding calendar year be used for determining any
remittance due Borrower pursuant to this Agreement in a subsequent year.




                                 2
                                 
                b.   Escrow Agent shall determine whether there have
been any Excess Deposits based upon analyzing and reconciling the certified 
quarterly statements submitted to Lender pursuant to Paragraph 9(a) of the 
Second Mortgage Modification and Consolidation Agreement.

                c.   In the event that a quarterly statement submitted
for a subsequent quarter shows that some of all of the Available Cash Flow
deposited for the previous quarters of such calendar year would not have
been deposited if calculations of Available Cash Flow had been determined
for all such quarterly periods (e.g., for a nine month period instead of
being determined quarterly), Escrow Agent shall remit the amount so
determined to be such Excess Deposit to the Borrower following such
determination.

                d.   To the extent any annual financial or
reconciliation statement or audit shall show that on an annual basis
Borrower would not have been entitled to a refund (i.e., no Excess Deposit
did in fact occur), Borrower shall within five (5) days of demand,
redeposit into the Reserve Account the amount of any money paid Borrower by
Escrow Agent as an Excess Deposit together with interest at the applicable
fixed interest rate set forth in the Note and any failure to make such
payment within five (5) days of demand shall constitute a default under the
Second Mortgage Modification and Consolidation Agreement, at Lender's
option, affording Lender with all rights and remedies as provided in the
Second Mortgage Modification and Consolidation Agreement respecting
Mortgagor defaults.




                                 3
          2.    Except as herein contained, all the provisions of the
Reserve Escrow Agreement and Second Mortgage Modification and Consolidation
Agreement shall continue to remain unchanged and in full force and effect
and Borrower, Lender and Escrow Agent hereby ratify and reaffirm all of
such provisions, agree to comply with each and everyone of such provisions,
and Borrower confirms that it has no defense or offset to its liability to
pay the Consolidated Indebtedness with fixed and residual interest and the
yield maintenance amount due Lender in accordance with the terms of the
Second Mortgage Modification and Consolidation Agreement.

          3.    Borrower represents and warrants that it has full power
and authority to execute this Agreement for the uses and purposes herein
contained.

          4.    This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns.

          The party or parties executing this Agreement for and on behalf
of Borrower are doing so in their capacity of Trustee and not as
individuals.  As such, any liability for breaching any of the Borrower's
obligations hereunder shall be limited to the Premises, trust assets and,
the moneys deposited in escrow under this Agreement.

          Without limitation on the foregoing, but in addition thereto,
neither Borrower nor any Trustee, advisor or any other entity shall be
personally liable in any manner or to any extent under or in connection
with this Agreement or any other agreement or instrument entered into in
connection herewith; provided, however, that the foregoing shall not affect
or impair any obligations under a certain Indemnity and Payment Agreement
of even date herewith given by Carlyle Real Estate Limited Partnership-XV
and Carlyle Real Estate Limited Partnership-XVI to Lender.








                                 4
          
          IN WITNESS WHEREOF, the parties hereto have executed this
Agreement on the day and year first above written.
