this Section.

               5. Severability. Any provision of this Agreement which is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

               6. Integration. This Guarantee and the other Loan Documents
represent the agreement of the Loan Parties, the Collateral Agent and the
Lenders with respect to the subject matter hereof, and there are no promises,

breach of any of the terms and conditions hereof. No failure to exercise, nor
any delay in exercising, on the part of the Collateral Agent or any Lender, any
right, power or privilege hereunder shall operate as a waiver thereof. No single
or partial exercise of any right, power or privilege hereunder shall preclude
any other or further exercise thereof or the exercise of any other right, power
or privilege. A waiver by the Collateral Agent or any Lender of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Collateral Agent or such Lender would otherwise have
on any future occasion.

               (c) The rights and remedies herein provided are cumulative, may
be exercised singly or concurrently and are not exclusive of any other rights or

direct or indirect, by the Secured Parties over the management or any other
aspect of the operation of any Grantor, which ownership and control remain
