the prior written consent of the Creditor.



		13.	Waiver



		13.1	The failure of either Party to insist on the strict performance of any provision of this Agreement or
to exercise any right, power or remedy upon a breach hereof shall not constitute a waiver of any provision of this Agreement or limit
such Party’s right thereafter to enforce any provision or exercise any right.



		14.	Modification



		14.1	No modification of this Agreement shall be valid unless made in writing and duly executed by both Parties.

the economic or legal substance of the transactions contemplated hereby are not affected in any manner materially adverse to any Party
hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties hereto
shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties hereto as closely as possible
in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.
