shall be true and correct in all material respects on and as of the date hereof
(other than representations and warranties in any such Loan Document which
expressly speak as of a specific date, which shall have been true and correct in
all material respects as of such specific date) and no Default or Event of
Default has occurred and is continuing as of the date hereof.

     

    (b)           This
Amendment has been duly executed and delivered by each Loan Party and
constitutes a legal, valid and binding obligation of such Loan Party,

generally and subject to general principles of equity, regardless of whether
considered in a proceeding in equity or at law.

    (c)           Execution
and delivery by the Borrower of this Amendment, and consummation of the
transactions contemplated hereby, (i) do not require any consent or approval of,

liquidity forecasts of the Borrower and its Subsidiaries on a monthly basis
through June 2010 and on a quarterly basis through December 2010, as furnished
to the Administrative Agent, have been prepared in good faith by the Borrower
and based on assumptions believed by the Borrower to be reasonable at the time
furnished to the Administrative Agent (it being recognized that such projections
are not to be viewed as facts and that actual results during the period or
periods covered by any such projections may differ from the projected results,
and such differences may be material).

     

    (e)           The
Schedules to the Pledge and Security Agreement attached hereto as Exhibit I are true and

together shall constitute one and the same agreement.  Signature pages
may be detached from multiple separate counterparts and attached to a single
counterpart so that all signature pages are attached to the same

attached hereto reflects the Revolving Credit Commitments as of the Fourth

discharges each Lender, each Issuer, the Administrative Agent, the Syndication
Agent, the Documentation Agent and all affiliates, partners, subsidiaries,
officers, employees, agents, attorneys, principals, directors and shareholders

and all claims, demands, causes of action, obligations, remedies, suits, damages
and liabilities of any nature whatsoever, whether now known, suspected or
claimed, whether arising under common law, in equity or under statute, which the
Borrower ever had or now has against any of the Releasees (a) which may have
arisen at any time prior to the date hereof and (b) which were in any manner
related to this Amendment, the Credit Agreement, any other applicable Loan
Document or related documents, instruments or agreements or the enforcement or
attempted or threatened enforcement by any of the Releasees of any of their
respective rights, remedies or recourse related thereto (collectively, the
“Released
Claims”).  The Borrower covenants and agrees never to commence,
voluntarily aid in any way, prosecute or cause to be commenced or prosecuted
