2.Amendment to Credit Agreement. On the Amendment No. 1 Effective Date, the Credit Agreement shall be amended as follows:

3.Conditions: Notwithstanding the foregoing, this Amendment shall not become effective unless and until such date (the “Amendment No. 1 Effective Date”) as the following conditions are satisfied:

4.Representations and Warranties. Borrower repeats and reaffirms the representations and warranties set forth in Article V of the Credit Agreement, except to the extent that such representations and warranties relate solely to an earlier date. Borrower also represents and warrants that the execution,

delivery and performance of this Amendment, and the documents required herein, are within the corporate powers of Borrower, have been duly authorized by all necessary corporate action and do not and will not (i) require any consent or approval of the shareholders of Borrower; (ii) violate any provision of the articles of incorporation or by-laws of Borrower or of any law, rule, regulation, order, writ, judgment, injunction, decree, determination or award presently in effect having applicability to Borrower or any subsidiary; (iii) require the consent or approval of, or filing a registration with, any governmental body, agency or authority; or (iv) result in any breach of or constitute a default under, or result in the imposition of any lien, charge or encumbrance upon any property of Borrower or any subsidiary pursuant to, any indenture or other agreement or instrument under which Borrower or any subsidiary is a party or by which it or its properties may be bound or affected. This Amendment constitutes legal, valid and binding obligations of Borrower enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy or similar laws affecting the enforceability of creditors' rights generally.

5.Obligations Enforceable, Etc. Borrower acknowledges and agrees that its obligations under the Credit Agreement are not subject to any offset, defense or counterclaim assertable by Borrower and that the Credit Agreement and the Loan Documents are valid, binding and fully enforceable according to their respective terms. Except as expressly provided above, the Credit Agreement and the Loan Documents shall remain in full force and effect, and this Amendment shall not release, discharge or satisfy any present or future debts, obligations or liabilities to the Lender of Borrower or of any debtor, guarantor or other person or entity liable for payment or performance of any of such debts, obligations or liabilities of Borrower, or any security interest, lien or other collateral or security for any of such debts, obligations or liabilities of Borrower or such debtors, guarantors, or other persons or entities, or waive any default, and the Lender expressly reserves all of its rights and remedies with respect to Borrower and all such debtors, guarantors or other persons or entities, and all such security interests, liens and other collateral and security. This is an amendment and not a novation. Without limiting the generality of the foregoing, all present and future debts, obligations and liabilities of Borrower under the Credit Agreement, as amended, are and shall continue to be secured by the Pledge and Security Agreement and the Intellectual Property Security Agreement given by the Borrower, and shall continue to be guaranteed by the Guaranty (which Guaranty is secured by the Pledge and Security Agreement given by the Guarantor).

6.Fees and Expenses. As contemplated by Section 9.01(a) of the Credit Agreement, Borrower shall be responsible for the payment of all fees and out-of-pocket disbursements incurred by the Lender in connection with the preparation, execution and delivery of this Amendment.

7.Entire Agreement. This Amendment and the other documents referred to herein contain the entire agreement between the Borrower and the Lender with respect to the subject matter hereof, superseding all previous communications and negotiations, and no representation, undertaking, promise or condition concerning the subject matter hereof shall be binding upon the Lender unless clearly expressed in this Amendment or in the other documents referred to herein.

8.Miscellaneous. The provisions of this Amendment shall inure to the benefit of and be binding upon any successor to any of the parties hereto.

This Amendment shall be governed by and construed in accordance with the internal laws of the State of California. This Amendment may be signed in any number of counterparts with the same effect as if the signatures thereto and hereto were upon the same instrument.
