advice satisfactory to the Agent that such Lender has executed this Letter

The Forbearance

otherwise modified by this Letter Amendment, are and shall continue to be in
full force and effect and are hereby in all respects ratified and
confirmed.  The execution, delivery and effectiveness of this Letter
Amendment shall not, except as expressly provided herein, operate as a waiver of
any right, power or remedy of any Secured Party or the Agent under any of the
Loan Documents, nor constitute a waiver of any provision of any of the Loan
Documents.  Nothing contained in this Letter Amendment and no action
by, or inaction on the part of, any Secured Party or the Agent shall, or shall
be deemed to, directly or indirectly (i) constitute a consent to or waiver of
any past, present or future violation of any provision of the Credit Agreement
or any other Loan Document, (ii) except as expressly set forth herein, amend,
modify or operate as a waiver of any provision of the Credit Agreement or any
other Loan Document or of any right, power, or remedy of the Agent or any
Secured Party thereunder or (iii) constitute a course of dealing or other basis
for altering any obligation of the Loan Parties under the Loan Documents or any
other contract or instrument. The Loan Parties and the Required Lenders hereby
agree that this Letter Amendment shall be a Loan Document for all purposes of
the Credit Agreement and the other Loan Documents.




Each Loan Party
ratifies and reaffirms the validity and enforceability (without defense,
counterclaim or offset of any kind and not subject to any avoidance, reduction,
recharacterization, subordination (whether equitable, contractual or otherwise
but subject to the Intercreditor Amendment), counterclaim, cross-claim, defense,
disallowance, impairment, objection or any challenges under any applicable Law
or by any Person) of the Liens and security interests granted to secure any of
the Obligations to and for the benefit of the Secured Parties, pursuant to the
Loan Documents.  Each Loan Party acknowledges and agrees that all such
Liens and security interests granted by it secure, and shall continue to secure,
the Obligations and the Guaranties from and after the date hereof.




In consideration of
the Lenders’ execution and delivery of this Letter Amendment, each Loan Party
and each of their successors and assigns (including, without limitation, any
receiver or trustee, collectively, the “Releasors”) does
hereby forever acquit, waive, release and discharge each of the Agent and each
Lender party hereto and each of their respective successors, assigns,
affiliates, directors, officers, employees, agents, attorneys, consultants,
advisors and other Related Parties (collectively, the “Releasees”) of and
from any and all claims (including, without limitation, any liabilities,
damages, demands and causes of action to the extent arising therefrom)
whatsoever, in law or in equity, whether known or unknown, which the Releasors
ever had, have now, or hereinafter can, shall or may have against any Releasee
by reason of (a) any matter arising on or prior to the date hereof out of the
Credit Agreement, the Forbearance Agreement or the other Loan Documents and (b)
any and all other actions or omissions relating in any way thereto done or
omitted to be done on or prior to the date hereof.  This paragraph
shall survive (i) the expiration or termination of the Forbearance Period, of
the Forbearance Agreement and of this Letter Amendment and (ii) the termination
of the Credit Agreement, the payment in full of all Obligations and the
termination of all Commitments.




This Letter
Amendment may be executed by one or more of the parties to this Letter Amendment
on any number of separate counterparts, and all of said counterparts taken
together shall be deemed to constitute one and the same
instrument.  Any party hereto may execute and deliver a counterpart of
this Letter Amendment by delivering by facsimile transmission or electronic mail
in portable document format a signature page of this Letter Amendment signed by
such party, and such signature shall be treated in all respects as having the
same effect as an original signature.




This Letter
Amendment shall be governed by, and construed in accordance with, the laws of
the State of New York.
