6. Effectiveness of Debt Documents. Except as expressly amended by this
Amendment, all terms of the Agreement, as well as the Note and all of the other
Debt Documents, shall remain in full force and effect. To the extent any terms
and conditions in any of the Debt Documents shall contradict or be in conflict
with any terms or conditions of the amended Debt Documents, after giving effect

amended hereby. In connection herewith, Borrower shall execute such amendments
to the other Debt Documents or re-execute such of the other Debt Documents as
Lender shall request.

7. No Waiver of Remedies. Except as specifically provided herein, Lender
expressly reserves any and all rights and remedies at any time available to it
in connection with the Loan, whether arising under the Note, the Agreement
and/or any of the other Debt Documents, at law, in equity or otherwise. No
failure to exercise, or delay by Lender in exercising, any right, remedy, power
or privilege under or in connection with the Note, the Agreement and/or any of
the other Debt Documents shall preclude any other or further exercise thereof,

all such rights, remedies, powers and privileges shall be cumulative and not
exclusive of one another.

8. Entire Agreement. The parties acknowledge and agree that there are no other
agreements or representations, either oral or written, express or implied, in
connection with the Indebtedness that are not embodied in this Amendment, the
Agreement and the other Debt Documents, which, together represent a complete
integration of all prior and contemporaneous agreements and understandings of

obligations under the Note, the Agreement (as amended by this Amendment) or any
of the other Debt Documents and any purported such assignment shall be void.

Agreement) and the other Debt Documents, either together or separately, in
accordance with the Agreement. Without in any way limiting the foregoing, the
Note, the Agreement (as amended by this Amendment) and other Debt Documents
shall be binding upon the successors and legal representatives of Borrower.

10. Construction. The parties acknowledge and agree that each of them and their
respective counsel have reviewed and contributed substantively and materially to
the content of this Amendment and, as a result, this Amendment, and any
ambiguities it might contain, shall not be construed more strictly against or in
favor of either party on the basis that this Amendment, or any provision herein,
was drafted by one or the other party.
