Amendment shall apply and be effective only with respect to the provisions of

of the parties hereunder shall be governed by, and shall be construed and
enforced in accordance with, the laws of the State of New York without regard to
conflict of laws principles.

                  7. Counterparts. This Amendment may be executed in any number
of counterparts, each of which when so executed and delivered shall be deemed an
original, but all such counterparts together shall constitute but one and the
same instrument. The delivery of an executed signature of this Amendment by
facsimile transmission shall be effective as delivery of a manually executed
counterpart hereof.

other purpose or be given any substantive effect.
