                           (a) This Guaranty is and is intended to be a
         continuing guaranty of payment of the Indebtedness, independent of and
         in addition to any other guaranty, endorsement, collateral or other
         agreement held by the Agent or the Lenders therefor or with respect
         thereto, whether or not furnished by the Guarantor, The obligations of
         the Guarantor to repay the Indebtedness hereunder shall be unlimited.
         Notwithstanding anything to the contrary in this Guaranty, the
         Guarantor hereby irrevocably waives all rights which may have arisen in
         connection with this Guaranty to be subrogated to any of the rights
         (whether contractual, under the Bankruptcy code, including section 509
         thereof, under common law or otherwise) of the Agent or any Lender
         against the Debtor or against any collateral security or guarantee or
         right of offset held by the Agent or any Lender for the payment of the
         Indebtedness. The Guarantor hereby further irrevocably waives all
         contractual, common law, statutory or other rights of reimbursement,
         contribution, exoneration or indemnity (or any similar right) from or
         against the Debtor or any other Person which may have arisen in
         connection with this Guaranty So long as the Indebtedness remains
         outstanding, if any amount shall be paid by or on behalf of the Debtor
         to the Guarantor on account of any of the fights waived in this
         paragraph, such amount shall be held by the Guarantor in trust,
         segregated from other funds of such Guarantor, and shall, forthwith
         upon receipt by such Guarantor, be turned over to the Agent in the
         exact form received by the Guarantor (duly endorsed by the Guarantor to
         the Agent if required), to be applied against the Indebtedness, whether
         matured or unmatured, in such order as the Agent may determine. The
         provisions of this paragraph shall survive the term of this Guaranty
         and the payment in full of the Indebtedness and the termination of the
         Commitments. Notwithstanding the foregoing, in the event of the
         bankruptcy or insolvency of the Debtor, the Agent, on behalf of the
         Lenders, shall be entitled notwithstanding the foregoing, to file in
         the name of the Guarantor or in its own name a claim for any and all
         indebtedness owing to the Guarantor by the Debtor, vote such claim and

         to the Guarantor and all monies received from the Debtor or for its
         account by the Guarantor in respect thereof shall be received in trust
         for the Agent and the Lenders and forthwith upon receipt shall be paid
         over to the Agent, for the benefit of the Lenders, until all of the
         Indebtedness has been paid in full. This assignment and postponement Is
         independent of and severable from this Guaranty and shall remain in
         full force and effect whether or not the Guarantor is liable for any
         amount under this Guaranty.

                           (c) This Guaranty is absolute and unconditional and
         shall not be changed or affected by any representation, oral agreement,
         act or thing whatsoever, except as herein provided. This Guaranty is
         intended by the Guarantor to be the final, complete and exclusive
         expression of the guaranty agreement between the Guarantor and the
         Agent. No modification or amendment of any provision of this Guaranty
         shall be effective unless in writing and signed by a duly authorized
