execute and deliver the proposed Amendment as presented to us at this time.

                 Nonetheless, we are aware of the Borrowers' and our position as
to the need to obtain the releases and to amend the Credit Agreement to permit
the transactions contemplated by the Amendment. Therefore, reserving our rights
and positions set our prior notices to the Agent, we hereby agree and consent to
those pc Amendment that would not otherwise become effective unless our
agreement received.
