10.    RELEASE.

10.1    In consideration of the agreements of Agent and each Lender contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Borrower, on behalf of itself and its successors, assigns and other legal representatives (Borrower and all

In furtherance of this intention, Borrower, on behalf of itself and each other Releasor, expressly waives any statutory or common law provision that would otherwise prevent the release set forth above from extending to claims that are not currently known or suspected to exist in any Releasor’s favor at the time of executing this Amendment and which, if known by Releasors, might have materially affected the agreement as provided for hereunder. Borrower, on behalf of itself and each other Releasor, acknowledges that it is familiar with Section 1542 of California Civil Code:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.

10.3    Borrower, understands, acknowledges and agrees that the release set forth above may be pleaded as a full and complete defense and may be used as a basis for an injunction against any action, suit or other proceeding which may be instituted, prosecuted or attempted in breach of the provisions of such release.

10.4    Borrower, agrees that no fact, event, circumstance, evidence or transaction which could now be asserted or which may hereafter be discovered shall affect in any manner the final, absolute and unconditional nature of the release set forth above.

11.    COVENANT NOT TO SUE. Borrower, on behalf of itself, each Releasor and its successors, assigns and other legal representatives, hereby absolutely, unconditionally and irrevocably, covenants and agrees with and in favor of each Releasee that it will not sue (at law, in equity, in any regulatory proceeding or otherwise) any Releasee on the basis of any Claim released, remised and discharged by

Borrower, pursuant to Section 10.1 above. If Borrower, or any of its successors, assigns or other legal representations violates the foregoing covenant, Borrower, for itself and each other Releasor, agrees to pay, in addition to such other damages as any Releasee may sustain as a result of such violation, all attorneys’ fees and costs incurred by any Releasee as a result of such violation.

12.    ENTIRE AGREEMENT. This Amendment, and the terms and provisions hereof, the Credit Agreement and the other Loan Documents constitute the entire understanding and agreement between the parties hereto with respect to the subject matter hereof and supersede any and all prior or contemporaneous amendments or understandings with respect to the subject matter hereof, whether express or implied, oral or written.

13.    REAFFIRMATION OF OBLIGATIONS. Borrower hereby (a) acknowledges and reaffirms its obligations owing to Agent, the Bank Product Providers, and each other member of the Lender Group under each Loan Document to which it is a party, and (b) agrees that each of the Loan Documents to which it is a party is and shall remain in full force and effect. Borrower hereby (i) further ratifies and reaffirms the validity and enforceability of all of the Liens and security interests heretofore granted, pursuant to and in connection with the Guaranty and Security Agreement or any other Loan Document, to Agent, on behalf and for the benefit of the Lender Group and the Bank Product Providers, as collateral security for the obligations under the Loan Documents in accordance with their respective terms, and (ii) acknowledges that all of such Liens and security interests, and all Collateral heretofore pledged as security for such obligations, continue to be and remain collateral for such obligations from and after the date hereof (including, without limitation, from after giving effect to this Amendment).

15.    CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER; JUDICIAL REFERENCE. THIS AMENDMENT SHALL BE SUBJECT TO THE PROVISIONS REGARDING CHOICE OF LAW AND VENUE, JURY TRIAL WAIVER, AND JUDICIAL REFERENCE SET FORTH IN SECTION 12 OF THE CREDIT AGREEMENT, AND SUCH PROVISIONS ARE INCORPORATED HEREIN BY THIS REFERENCE, MUTATIS MUTANDIS.

16.    SEVERABILITY. In case any provision in this Amendment shall be invalid, illegal or unenforceable, such provision shall be severable from the remainder of this Amendment and the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.
