capital of Panavision as governed by Section 108(e)(6) of the Code.

     This Letter Agreement shall be deemed to be a contract made under the laws
of the State of Delaware, and for all purposes shall be governed by and
construed in accordance with the laws of said State, without regard to conflicts
of law principles thereof.

which shall be considered one and the same agreement and shall become effective
when one or more counterparts have been signed by each of the parties and
delivered to the other party.
