jointly and severally represent and warrant as follows:

                  (a)  this Amendment has been duly authorized, executed and
         delivered on its behalf, and the Market Street Purchase Agreement, as
         so amended, and each of the other Transaction Documents to which any
         Seller Party is a party constitutes such Seller Party's legal, valid

          (b)  This Amendment may be executed in any number of counterparts and
by the different parties hereto in separate counterparts, each of which when
so executed shall be deemed to be an original, and all of which together shall
constitute one and the same agreement.

          (c)  Any reference to the Market Street Purchase Agreement contained
in any notice, request, certificate or other document executed concurrently
