Lender, subject to paragraph 7.B., to exercise its rights to accelerate the
maturity of the indebtedness secured by the Mortgage and any and all other
rights available to Lender under the Loan Documents or at law or in equity.

         13. RELEASE. As additional consideration for the modification of the
terms of the Original Loan, as provided herein, Borrower does hereby release and
forever discharge Lender and the City of Detroit, their agents, servants,
employees, directors, officers, attorneys, affiliates, successors and assigns
from all liabilities, obligations, actions and causes of action whatsoever
related to the Loan which Borrower may now have or claim to have against Lender
or the City of Detroit as of the date hereof, whether presently known or
unknown, of every nature and extent whatsoever on account of or in any way
touching, concerning, arising out of or founded upon the Mortgage, as modified
hereby, including, but not limited to, all such loss or damage of any kind
heretofore sustained, or that may arise as a consequence of the dealings between
the parties up to the date of this Agreement. Borrower acknowledges that, as of
the date of this Agreement, there are no statements, agreements, waivers,
estoppels or representations made by Lender which would constitute a claim,
defense, counterclaim or right of offset in any foreclosure action that may
hereafter be instituted by Lender under the Mortgage, or in any independent
claim or action that may hereafter be brought by Borrower against Lender. This
agreement and covenant on the part of Borrower is contractual, and not a mere
recital, and the parties acknowledge and agree that no liability whatsoever is
admitted on the part of any party, except Borrower's indebtedness to Lender
under the Mortgage, as modified hereby, and that all agreements and
understandings between Borrower and Lender are expressed and embodied in the
Mortgage, as modified hereby and in the Note, as modified by the Third Note
Modification Agreement. In the event that Lender is involved in litigation
concerning the subject matter of this Agreement, Lender shall be

                                       6

entitled to receive from Borrower all of Lender's reasonable and necessary costs
for such litigation, including Lender's reasonable attorneys' fees and costs
incurred through all trial, appellate and other proceedings.

         14. KNOWLEDGE. Borrower acknowledges that (A) it has thoroughly read
and reviewed the terms and provisions of this Agreement and is familiar with
same, that the terms and provisions contained herein are clearly understood by
Borrower and have been fully and unconditionally consented to by Borrower, (B)
it has had full benefit and advice of counsel of its own selection, or the

has freely, voluntarily, with full knowledge, and without duress, executed this
Agreement, (D) in executing this Agreement, it is not relying on any other
representations, either written or oral, express or implied, made to it by
Lender, and (E) that the consideration received by it hereunder has been actual
and adequate.

         15. WAIVER OF JURY TRIAL. THE UNDERSIGNED HEREBY KNOWINGLY, VOLUNTARILY
AND INTENTIONALLY WAIVE THE RIGHT WHICH THE UNDERSIGNED MAY HAVE TO A TRIAL BY
JURY WITH RESPECT TO ANY LITIGATION BETWEEN THE PARTIES HERETO, INCLUDING, BUT
NOT LIMITED TO, WITH RESPECT TO ANY AND ALL CAUSE OR CAUSES OF ACTION, DEFENSES,
COUNTERCLAIMS, CROSSCLAIMS, THIRD PARTY CLAIMS AND INTERVENORS' CLAIMS,
REGARDLESS OF THE CAUSE OR CAUSES OF ACTION, DEFENSES OR COUNTERCLAIMS ALLEGED
OR THE RELIEF SOUGHT BY SUCH PARTY, AND REGARDLESS OF WHETHER SUCH LITIGATION IS
BASED ON, ARISES OUT OF, UNDER OR IN CONNECTION WITH THE LOAN OR THIS AGREEMENT,
THE NOTE, GUARANTY OR ANY OF THE OTHER LOAN DOCUMENTS, OR OUT OF ANY ALLEGED
CONDUCT OR COURSE OF CONDUCT, DEALING OR COURSE OF DEALING, STATEMENTS (WHETHER
VERBAL OR WRITTEN) OR ACTIONS OF THE PARTIES HERETO, OR OTHERWISE.

         17. ENTIRE AGREEMENT. Borrower acknowledges that there are no other
agreements or representations, either oral or written, express or implied, not
embodied in this Agreement and the Loan Documents, which, together, represent a
complete integration of all prior and contemporaneous agreements and
understandings of the parties.

Obligations of Borrower under the Loan Documents.

number of counterparts, each of which, when so executed and delivered, shall be
and constitute an original and one and the same document.

         20. MODIFICATION MUST BE IN WRITING. This Agreement may not be changed
or terminated, except in a writing signed by Lender and Borrower.

         21. CAPTIONS. All captions or headings contained in this Agreement are
provided for convenience and ease of reference only, and are in no way intended
