                  1. The Lenders hereby waive any Event of Default that has

hereinafter defined).

                  2. Section 8.05 of the Credit Agreement is hereby amended by

Amendment, each of Holdings and the Borrower hereby represents and warrants that
(i) the representations and warranties contained in the Credit Agreement are

be true and correct in all material respects only as of such specified date) and
(ii) there exists no Default or Event of Default on the First Amendment
Effective Date, in each case after giving effect to this Amendment.

PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW
OF THE STATE OF NEW YORK.

Lenders (i) shall have signed a counterpart hereof (whether the same or
different counterparts) and (ii) shall have delivered (including by way of
facsimile transmission) the same to the Administrative Agent.
