         determination) not in excess of, and securing liabilities otherwise

         4. The Borrower hereby represents and warrants that (i) no Default or
Event of Default exists on the Sixth Amendment Effective Date (as defined
below), both before and after giving effect to this Amendment and (ii) all of
the representations and warranties contained in the Secured PIK/Term Credit

have been expressly consented to in writing by the Lenders since the date on
which such representations and warranties were first made) shall be true and
correct in all material respects on and before the Sixth Amendment Effective
Date with the same effect as though such representations and warranties had been
made on and as of such date (it being understood that any representation or
warranty made as of a specific date shall be true and correct in all material
respects as of such specific date).

         5. This amendment is limited as specified and shall not constitute a
modification, amendment or waiver of any other provision of the Secured PIK/Term
Credit Agreement or any other Loan Documents.

         6. This Amendment may be executed in any number of counterparts and by
the different parties hereto on separate counterparts, each of which
counterparts when executed and delivered shall be an original, but all of which
shall together constitute one and the same instrument. A complete set of
counterparts shall be lodged with the Borrower and the Administrative Agent.

         7. THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE
