(iv) This Amendment is not a novation and the terms and conditions of this Amendment shall be in addition to and supplemental to all terms and conditions set forth in the Loan Documents.  Nothing in this Amendment is intended, or shall be construed, to constitute an accord and satisfaction of any Loan Party’s Secured Obligations under or in connection with the Loan and Security Agreement and any other Loan Document or to modify, affect or impair the perfection or continuity of Agent’s security interest in, (on behalf of itself and Lender) security titles to or other liens on any Collateral for the Secured Obligations.

(b) Conditions.  For purposes of determining compliance with the conditions specified in Section 3, each Lender that has signed this Amendment shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless Agent shall have received notice from such Lender prior to the Amendment Effective Date specifying its objection thereto.

(c) Release.  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, each Loan Party, on behalf of itself and its successors, assigns, and other legal representatives, hereby fully, absolutely, unconditionally and irrevocably releases, remises and forever discharges Agent and each Lender, and their respective successors and assigns, and their respective present and former shareholders, affiliates, subsidiaries, divisions, predecessors, directors, officers, attorneys, employees, agents and other representatives (Agent, Lender and all such other persons being hereinafter referred to collectively as the “Releasees” and individually as a “Releasee”), of and from all demands, actions, causes of action, suits, covenants, contracts, controversies, agreements, promises, sums of money, accounts, bills, reckonings, damages and any and all other claims, counterclaims, defenses, rights of set-off, demands and liabilities whatsoever of every name and nature, known or unknown, suspected or unsuspected, both at law and in equity, which each Loan Party, or any of its successors, assigns, or other legal representatives may now or hereafter own, hold, have or claim to have against the Releasees or any of them for, upon, or by reason of any circumstance, action, cause or thing whatsoever which arises at any time on or prior to the day and date of this Amendment, including, without limitation, for or on account of, or in relation to, or in any way in connection with the Loan and Security Agreement, or any of the other Loan Documents or transactions thereunder or related thereto (collectively, the “Released Claims”).  Each Loan Party understands, acknowledges and agrees that the release set forth above (the “Release”) 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

4

instituted, prosecuted or attempted in breach of the provisions of such release.  Each Loan Party 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.  Without limiting the generality of the foregoing, each Loan Party hereby waives the provisions of any statute or doctrine that prevents a general release from extending to claims unknown by the releasing party, including, without limitation, California Civil Code Section 1542, which provides:

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

Each Loan Party acknowledges that the agreements in this Section are intended to be in full satisfaction of all or any alleged injuries or damages arising in connection with the Released Claims.  Each Loan Party acknowledges that the Release constitutes a material inducement to Agent and Lender to enter into this Amendment and that Agent and Lender would not have done so but for Agent’s and Lender’s expectation that the Release is valid and enforceable in all events.

(d) No Reliance.  The Loan Parties hereby acknowledge and confirm to Agent and Lender that the Loan Parties are executing this Amendment on the basis of their own investigation and for their own reasons without reliance upon any agreement, representation, understanding or communication by or on behalf of any other Person.

(e) Costs and Expenses.  The Loan Parties agree to pay to Agent as required under the Loan Agreement, after giving effect to this Amendment, the reasonable and documented out-of-pocket fees and expenses of Agent and Lender party hereto and the reasonable and documented out-of-pocket fees and disbursements of counsel to Agent and Lender party hereto in connection with the negotiation, preparation, execution and delivery of this Amendment and any other documents to be delivered in connection herewith on the Amendment Effective Date or after such date.

(f) Binding Effect.  This Amendment binds and is for the benefit of the successors and permitted assigns of each party.

5

(h) Complete Agreement; Amendments.  This Amendment and the Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements with respect to such subject matter.  All prior agreements, understandings, representations, warranties, and negotiations between the parties about the subject matter of this Amendment and the Loan Documents merge into this Amendment and the Loan Documents.

(i) Severability of Provisions.  Each provision of this Amendment is severable from every other provision in determining the enforceability of any provision.

(j) Counterparts.  This Amendment may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, is an original, and all taken together, constitute one Amendment.  Delivery of an executed counterpart of a signature page of this Amendment by facsimile, portable document format (.pdf) or other electronic transmission will be as effective as delivery of a manually executed counterpart hereof.
