Parties now have, or in the future may have, conferred upon Borrower Parties by
virtue of the provisions of Section 1542 of the Civil Code of the State of
California which provides as follows:

      A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES
      NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING
      THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS
      SETTLEMENT WITH THE DEBTOR.

In this connection, Borrower Parties hereby agree, represent, and warrant that
they realize and acknowledge that factual matters now unknown to one or more of
the Borrower Parties may have given or may hereafter give rise to causes of
action, claims, demands, debts, controversies, damages, costs, losses and
expenses which are presently unknown, unanticipated and unsuspected, and
Borrower Parties further agree, represent and warrant that the release herein
contained has been negotiated and agreed upon in light of that realization and
that Borrower

                                       9
<PAGE>

Parties nevertheless hereby intend to release, discharge and acquit all parties
so released from any such unknown claims.

         2.4 SAME INDEBTEDNESS; PRIORITY OF LIENS NOT AFFECTED. This Agreement
and the execution of other documents contemplated hereby do not constitute the
creation of a new debt or the extinguishment of the debt evidenced by the Loan
Documents, nor will they in any way affect or impair the liens and security
interests created by the Loan Documents, which New Borrower acknowledges to be
valid and existing liens and security interests in the Project. New Borrower
agrees that the lien and security interests created by the Security Instrument
continue to be in full force and effect, unaffected and unimpaired by this
Agreement or by the transfer of the Project or any collateral described in
financing statements filed in connection with the Loan Documents and that said
liens and security interests shall so continue in their perfection and priority
until the debt secured by the Loan Documents is fully discharged.

         2.5 PAYMENT OF TRANSACTION COSTS AND EXPENSES. Any or both of Borrower
Parties (pursuant to an agreement between them) shall pay at the time of
execution of this Agreement by Lender: (a) the legal fees and disbursements of
Lender's counsel, Bilzin Sumberg Baena Price & Axelrod LLP, in connection with
the preparation of this Agreement and the transactions contemplated in this
Agreement; (b) all recording costs and documentary stamps, or other taxes if
any, due upon the recording of this Agreement; and (c) the costs of updating
Lender's policy of title insurance insuring the Security Instrument to a current
date and endorsing such policy to include this Agreement in the description of
the Security Instrument with no additional exceptions, or, at Lender's option,
the cost of obtaining a new Lender's policy of title acceptable to Lender
insuring the Security Instrument as affected by this Agreement.

                                    ARTICLE 3

                              ADDITIONAL PROVISIONS

         3.1 CONSENT OF LENDER. Subject to the terms of this Agreement, Lender
hereby consents to the Requested Actions. Borrower Parties agree that this
Agreement shall not be deemed an agreement by Lender to consent to any other
transfer or conveyance of the Project or assumption of the Loan, or a consent to
any secondary financing or secondary encumbrance on the Project or New Borrower
or any interests in New Borrower except the existing Junior and Senior Mezzanine
Loans.

         3.2 UCC FILINGS. Each of the Borrower Parties hereby grants and
confirms unto Lender a first lien priority interest in all the Collateral (as
such term is defined in the Security Instrument) to the maximum extent permitted
by the Uniform Commercial Code ("UCC"). Each of the Borrower Parties hereby
further consents to the filing of any financing statements or UCC forms required
to be filed in the applicable states or any other applicable filing office
(collectively "FILINGS") in order to perfect said interest and, notwithstanding
anything contained in any of the Loan Documents to the contrary, in accordance
with the UCC, as amended subsequent to the making of the Loan, said Filings may
be made by Lender without the consent or signature of either of the Borrower
Parties.

Holdings III LP and Blackstone Real Estate Partners III F.F., L.P., each a

         3.4 REFERENCES TO LOAN DOCUMENTS. All references to the term "LOAN
DOCUMENTS" in the Security Instrument, the Loan Agreement and the other Loan
Documents shall hereinafter mean and refer to: (i) all of the Loan Documents
described therein; (ii) this Agreement; and (iii) any and all other agreements,
documents and other instruments evidencing, securing or in any manner related to
the documents executed in connection with or otherwise pertaining to this
Agreement.

                                    ARTICLE 4

                            MISCELLANEOUS PROVISIONS

         4.1 NO LIMITATION OF REMEDIES. No right, power or remedy conferred upon
or reserved to or by Lender in this Agreement is intended to be exclusive of any
other right, power or remedy conferred upon or reserved to or by Lender under
this Agreement, the Loan Documents or at law, but each and every remedy shall be
cumulative and concurrent, and shall be in addition to each and every other
right, power and remedy given under this Agreement, the Loan Documents or now or
subsequently existing at law.

         4.2 NO WAIVERS. Except as otherwise expressly set forth in this
Agreement, nothing contained in this Agreement shall constitute a waiver of any
rights or remedies of Lender under the Loan Documents or at law. No delay or
failure on the part of any party hereto in the exercise of any right or remedy
under this Agreement shall operate as a waiver, and no single or partial
exercise of any right or remedy shall preclude other or further exercise thereof
or the exercise of any other right or remedy. No action or forbearance by any
party hereto contrary to the provisions of this Agreement shall be construed to
constitute a waiver of any of the express provisions. Any party hereto may in
writing expressly waive any of such party's rights under this Agreement without
invalidating this Agreement.

         4.3 SUCCESSORS OR ASSIGNS. Whenever any party is named or referred to
in this Agreement, the heirs, executors, legal representatives, successors,
successors-in-title and assigns

                                       11
<PAGE>

of such party shall be included. All covenants and agreements in this Agreement
made by a party hereto shall bind and inure to the benefit of the heirs,
executors, legal representatives, successors, successors-in-title and assigns of
such party, whether so expressed or not.

         4.4 CONSTRUCTION OF AGREEMENT. Each party hereto acknowledges that it
has participated in the negotiation of this Agreement and no provision shall be
construed against or interpreted to the disadvantage of any party hereto by any
court or other governmental or judicial authority by reason of such party having
or being deemed to have structured, dictated or drafted such provision. Each of
the Borrower Parties at all times has had access to an attorney in the
negotiation of the terms of and in the preparation and execution of this
Agreement. Each of the Borrower Parties has had the opportunity to review and
analyze this Agreement for a sufficient period of time prior to execution and
delivery. No representations or warranties have been made by or on behalf of
Lender, or relied upon by Borrower Parties, pertaining to the subject matter of
this Agreement, other than those set forth in this Agreement. All prior
statements, representations and warranties, if any, are totally superseded and
merged into this Agreement, which represent the final and sole agreement of the
parties with respect to the subject matters. All of the terms of this Agreement
were negotiated at arm's length, and this Agreement was prepared and executed
without fraud, duress, undue influence or coercion of any kind exerted by any of
the parties upon the others. The execution and delivery of this Agreement is the
free and voluntary act of each of the Borrower Parties.

         4.5 INVALID PROVISION TO AFFECT NO OTHERS. If, from any circumstances
whatsoever, fulfillment of any provision of this Agreement or any related
transaction at the time performance of such provision shall be due, shall
involve transcending the limit of validity presently prescribed by any
applicable usury statute or any other applicable law, with regard to obligations
of like character and amount, then ipso facto, the obligation to be fulfilled
shall be reduced to the limit of such validity. If any clause or provision
operates or would prospectively operate to invalidate this Agreement, in whole
or in part, then such clause or provision only shall be deemed deleted, as
though not contained, and the remainder of this Agreement shall remain operative
and in full force and effect.

         4.6 NOTICES. Except as otherwise specifically provided to the contrary,
any and all notices, elections, approvals, consents, demands, requests and
responses ("COMMUNICATIONS") permitted or required to be given under this
Agreement and the Loan Documents shall not be effective unless in writing,

within the continental United States as such other party may designate by notice

Section. Receipt of Communications shall occur upon actual delivery but if

shall be deemed the date of receipt. Any Communication, if given to Lender, must
