shall continue to be fully bound one to another.

    5. Agreement Between Separation and CFC. The Services Agreement between

actions, proceedings, investigations, judgments, deficiencies, damages,
settlements, liabilities, and legal and other expenses (collectively "Losses")
as and when incurred, arising out of, in connection with or based upon any act
or omission, or alleged act or omission, by the indemnified party in connection
with its performance or non-performance hereunder. The indemnified party has to
give the indemnifying party prompt notice of any claim asserted or threatened
against it in respect of which indemnification is sought (though indemnification
shall not be conditioned upon receipt of such notice). Indemnification hereunder
is conditioned upon the indemnified party having acted in good faith and in a
manner believed to be in the best interests of the indemnifying party and within
the scope of authority set forth hereunder.

    8. Notices. All notices required or permitted hereunder shall be in writing
and mailed or sent by facsimile to the chief financial officer of the party
receiving the notice at its principal office.

    9. Assignment. Neither this Agreement nor any rights or obligations
hereunder may be transferred, assigned, or delegated, in whole or in part, by
any party without the written consent of all other parties to this Agreement.
Subject to the foregoing, this Agreement shall be binding upon and inure to the
benefit of and be enforceable by the parties hereto and their respective
successors and permitted assigns, but no other persons shall acquire or have any
rights under this Agreement.

    10. Choice of law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York, without reference to conflict
or choice of laws principles.

    IN WITNESS HEREOF, and intending to be legally bound, the parties have duly
