Agreement, the Notes and all other Loan Documents shall remain in full force and

          5.3  The execution, delivery and effectiveness of this Amendment shall

Documents, nor constitute a waiver of any provision contained therein, except as
specifically set forth herein.

          5.4  Each of the Borrowers and Guarantors hereby (i) reaffirms all of
its obligations and liabilities under the respective security agreements, pledge
agreements and other Loan Documents, including, without limitation, the
Collateral Documents Amendment, pursuant to which any Lien against property and
interests in property of such Person has been granted, and the Release Agreement
dated as of February 14, 2001,  which have been heretofore executed by such
Person in favor of the Agent for the benefit of the Holders (including, without
limitation, the holder of the Supplemental Term Loan Note) and (ii) acknowledges
and agrees that such security agreements, pledge agreements and other Loan
Documents remain in full force and effect, before and after giving effect to the
Amendment, for the benefit of the Agent and such other Holders, that the
security granted thereunder shall continue as security for the Obligations and
the Indebtedness evidenced by the Supplemental Term Loan Note, and that the
"Borrower Claims" described in such Release Agreement shall mean and extend to
the matters described therein whether existing, held or alleged heretofore or as
of the date of this Amendment, and which could, might or may be claimed to exist
through the date of this Amendment.

          5.5  Each of Parent and the other Guarantors agrees that it continues
to be liable, as a guarantor under the Loan Documents heretofore executed and
delivered thereby of the payment and performance of the Obligations and the
Indebtedness evidenced by the Supplemental Term Loan Note, whether incurred
prior to or after the effective date of the Amendment
