                                       10
<PAGE>

             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 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 (other than the liens and security
interest encumbering the Original Property Owner Interests), which New Borrower
acknowledges to be valid and existing liens and security interests in the
Collateral. New Borrower agrees that the lien and security interests created by
the Loan Documents (other than with respect to the Original Property Owner
Interests) 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, McKenna Long & Aldridge LLP, in connection with the
preparation of this Agreement and the transactions contemplated in this
Agreement; and (b) the costs of obtaining a Lender's "Eagle 9" insurance policy
insuring the collateral pledged to Lender pursuant to the Security Instrument as
affected by this Agreement, (c) the costs of obtaining a "Mezzanine Endorsement"
to New Property Owner's title insurance policy, in form and substance reasonably
satisfactory to Lender, and (d) all other costs and expenses incident to the
preparation, execution and recordation of this Agreement and the New Documents
and the consummation of the transaction contemplated hereby.

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

Parties.

                                   ARTICLE IV

                            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 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,
provided, however, the provisions of this Section 4.3 shall not be deemed or
construed to (a) permit, sanction, authorize or condone the assignment of all or
any part of the Project of the Collateral or any of New Property Owner's or New
Borrower's rights, title or interests in and to the Project or the Collateral,
except as expressly authorized in the Loan Documents; or (b) confer any right,
title, benefit, cause of action or remedy upon any person or entity not a party
hereto, which such party would not or did not otherwise possess.

         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

                                       13
<PAGE>

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,
