         (and after giving effect thereto including the incurrence or repayment
         of any Indebtedness in connection therewith): (x) the acquisition of
         each Rouse Property and (y) the disposition of each Property in the

         the fair value of such Indebtedness as would be reflected on the
         Parent's balance sheet.

         (e) The Credit Agreement is amended by deleting subsections (b) and (i)

Laws) relating to any Loan Party or any other Subsidiary; (ii) result in a
breach of or constitute a default under the declaration of trust, certificate or

documents of any Loan Party or any other Subsidiary, or any indenture, agreement
or other instrument to which any Loan Party or any other Subsidiary is a party
or by which it or any of its respective properties may be bound; or (iii) result
in or require the creation or imposition of any Lien upon or with respect to any
property now owned or hereafter acquired by any Loan Party or any other
Subsidiary other than in favor of the Agent for the benefit of the Lenders.




         (c) No Default. No Default or Event of Default has occurred and is
continuing as of the date hereof nor will exist immediately after giving effect
to this Amendment.

         Section 4. Reaffirmation of Representations. The Parent and the
Borrower each hereby repeats and reaffirms all representations and warranties
made by such Person to the Agent and the Lenders in the Credit Agreement and the
other Loan Documents to which it is a party on and as of the date hereof except
to the extent that such representations and warranties expressly relate solely
to an earlier date (in which case such representations and warranties were true
and accurate on and as of such earlier date) and except for changes in factual
circumstances not prohibited under the Loan Documents.

         Section 5. Reaffirmation of Guaranty by Guarantors. Each Guarantor
hereby reaffirms its continuing obligations to the Agent and the Lenders under

Agreement as amended by this Amendment.

Agent for the account of each Lender a modification fee in an amount equal to
0.15% of such Lender's Revolving Commitment.

         Section 8. Expenses. The Borrower shall reimburse the Agent upon demand
for all reasonable costs and expenses (including reasonable attorneys' fees)
incurred by the Agent in connection with the preparation, negotiation and
execution of this Amendment and the other agreements and documents executed and
delivered in connection herewith.

         Section 9. Benefits. This Amendment shall be binding upon and shall
inure to the benefit of the parties hereto and their respective successors and
assigns.

         Section 10. GOVERNING LAW. THIS AMENDMENT SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE COMMONWEALTH OF PENNSYLVANIA
APPLICABLE TO CONTRACTS EXECUTED, AND TO BE FULLY PERFORMED, IN SUCH
COMMONWEALTH.




         Section 11. Effect. Except as expressly herein amended, the terms and
conditions of the Credit Agreement and the other Loan Documents remain in full
force and effect. The amendments contained herein shall be deemed to have
prospective application only, unless otherwise specifically stated herein.

         Section 12. Counterparts. This Amendment may be executed in any number
of counterparts, each of which shall be deemed to be an original and shall be
binding upon all parties, their successors and assigns.
