of the Borrowers contained in the Waiver and the Amendments, as modified

fees payable under Section 5.3.3 of the Credit Agreement shall be payable in
arrears on the fifteenth day of each month (instead of the Quarterly Payment
Dates as specified in such section) and that such agreement shall survive the
Waiver Termination Date. In
order to induce the Lenders to enter into this Amendment, the Borrowers hereby
represent and warrant that, except with respect to the Excluded Items (as
defined in the Fourth Amendment), both before and after giving effect to this
Amendment, all of the representations and warranties contained in the Credit
Agreement and the other Loan Documents, including the Waiver and the

Credit Agreement with respect to such Subsidiary. Except

perfection or priority of any Lien or security interest securing the
Obligations, (ii) waive or impair any rights, powers or remedies of any Agent
or Lender under the Credit Agreement or any other Loan Document, except as
expressly set forth herein or therein, (iii) constitute an agreement by
any Agent or Lender or require any Agent or Lender to grant additional waivers
or waiver periods, or extend the term of the Credit Agreement or the time for
payment of any of the Obligations or (iv) require any Lender to make any
Loans, issue any Letters of Credit, or provide other extensions of credit to
the Borrowers. The
Borrowers agree, reaffirm and ratify that the failure to comply with any covenant
contained in the Waiver or any Amendment, as such covenants may have been
amended or waived and other than, to the extent applicable, the Excluded Items,
shall constitute an Event of Default and the waivers granted in the Waiver and
the Amendments shall terminate (i) immediately (without the need for further
notice of any kind) in the case of the Borrowers' failure to comply with a
covenant providing for a payment or prepayment to the Agents or the Lenders and
(ii) two Business Days after the date the Borrowers receive written notice
from an Agent (the "Notice Period") of the Borrowers' failure
to comply with any other covenant in the Waiver or any Amendment, provided that
in the event such failure is remedied within the Notice Period, such failure
shall not constitute an Event of Default and the waivers granted in the Waiver
and the Amendments shall not terminate. Each of
the Borrowers acknowledges that it has consulted with counsel and with such
other experts and advisors as it has deemed necessary in connection with the
negotiation, execution and delivery of this Amendment. This
Amendment may be executed in counterparts and by any party to this Amendment on
separate counterparts, each of which, when so executed, shall be deemed an
original, but all of such counterparts shall constitute one and the same
