obligations under this Amendment without the prior written consent of the Agent
and each Bank.

          (c)  This Amendment may be executed in any number of counterparts and
by the different parties on separate counterparts, and each such counterpart,
when so executed, shall be deemed to be an original, but all such counterparts
