Section 3. Temporary Waiver.

(a) The Borrower hereby informs the Lenders and acknowledges that the Borrower
may have failed to comply with the minimum net worth covenant set forth in
Section 6.17 of the Credit Agreement for the fiscal quarter ended December 31,
2008 which would result in an Event of Default under the Credit Agreement as of
December 31, 2008 (the “Existing Default”).

(b) The Lenders hereby agree, subject to the terms of this Agreement, to
temporarily waive the Existing Default until the date (“Waiver Termination
Date”) that is the earlier to occur of (i) May 15, 2009 and (ii) the date of the
occurrence of a Waiver Default (as defined below). The waiver set forth in this
Section 3(b) is temporary in nature and the Existing Default shall, unless
otherwise agreed to in writing by the Majority Revolving Lenders and the
Majority Lenders, be immediately and automatically reinstated on the Waiver
Termination Date and shall constitute an “Event of Default” under the Credit
Agreement and the other Credit Documents. The waiver by the Lenders described
above is contingent upon the satisfaction of the conditions precedent set forth
below and is limited to the Existing Default. This waiver is limited to the
extent described herein and shall not be construed to be a consent to or a
permanent waiver of the Existing Default or any other terms, provisions,
covenants, warranties or agreements contained in the Credit Agreement or in any
of the other Credit Documents or a waiver of any Default or Event of Default
that may hereafter occur. The Lenders reserve the right to exercise any rights
and remedies available to them in connection with any other present or future
defaults with respect to the Credit Agreement or any other provision of any
Credit Document.

(c) The Borrower and each Guarantor hereby agrees and acknowledges that (i) the
Existing Default has not been permanently waived as a result of this Agreement
and that such waiver is temporary in nature, and (ii) concurrent with the Waiver
Termination Date, all rights and remedies of the Lenders enjoined as a result of
this Section 3 shall, unless otherwise agreed to in writing by the Majority
Revolving Lenders and the Majority Lenders, be reinstated.

(d) The following shall constitute a “Waiver Default” under this Agreement:
(i) the failure of the Borrower or any Guarantor to comply with any covenant or
agreement contained in this Agreement; (ii) any representation or warranty
contained in this Agreement shall be incorrect in any material respect; or
(iii) the existence of any Default or Event of Default (other than the Existing
Default).
