9.    To the extent that any provision of this Amendment is determined by any
court or legislature to be invalid or unenforceable in whole or part either in a
particular case or in all cases, such provision or part thereof is to be deemed
surplusage. If that occurs, it does not have the effect of rendering any other
provision of this Amendment invalid or unenforceable. This Amendment is to be
construed and enforced as if such invalid or unenforceable provision or part
thereof were omitted.

10.    This Amendment may only be changed or amended by a written agreement
signed by all of the parties hereto. By the execution of this Amendment, Lender
is not to be deemed to consent to any future renewal or extension of the Loans.
This Amendment is deemed to be part of and integrated into the Credit Documents.

11.    THIS AMENDMENT AND THE OBLIGATIONS ARISING HEREUNDER SHALL BE GOVERNED
BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK APPLICABLE TO CONTRACTS MADE AND PERFORMED IN SUCH STATE, WITHOUT
REGARD TO THE CONFLICT OF LAW PRINCIPLES THEREOF.

12.    The parties to this Amendment acknowledge that each has had the
opportunity to consult independent counsel of their own choice, and that each
has relied upon such counsel's advice concerning this Amendment, the
enforceability and interpretation of the terms contained in this Amendment and
the consummation of the transactions and matters covered by this Amendment.

13.    Borrowers agree to pay all attorneys' fees and other costs incurred by
Lender or otherwise payable in connection with this Amendment (in addition to
those otherwise payable pursuant to the Credit Documents), which fees and costs
are to be paid as of the date hereof.

14.    This Amendment may be executed in any number of counterparts, each of
which when so executed is deemed to be an original and all of which taken
together constitute but one and the same agreement. Delivery of an executed
counterpart of this Amendment by facsimile or other electronic method of
transmission shall be equally as effective as delivery of an original executed
counterpart of this Amendment. Any party delivering an executed counterpart of
this Amendment by facsimile or other electronic method of transmission also
shall deliver an original executed counterpart of this Amendment but the failure
to deliver an original executed counterpart shall not affect the validity,
enforceability, and binding effect of this Amendment.

15.    THE BORROWERS, FOR THEMSELVES, THEIR SUBSIDIARIES (IF ANY) AND THE CREDIT
PARTIES AND LENDER HEREBY WAIVE ALL RIGHTS TO A TRIAL BY JURY IN ANY LITIGATION
RELATING TO THIS AMENDMENT OR THE DEBT AS AN INDUCEMENT TO THE EXECUTION OF THIS
AMENDMENT.
