(a) Notwithstanding any provision in this Agreement, the Notes, or any other Loan Document, it is the parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that a court of competent jurisdiction shall deem applicable hereto (which under the laws of the State of California shall be deemed to be the laws relating to permissible rates of interest on commercial loans) (the “Maximum Rate”). If a court of competent jurisdiction shall finally determine that Borrower has actually paid to Lender an amount of interest in excess of the amount that would have been payable if all of the Secured Obligations had at all times borne interest at the Maximum Rate, then such excess interest actually paid by Borrower shall be applied as follows: first, to the payment of principal outstanding on the Notes; second, after all principal is repaid, to the payment of Lender’s accrued interest, costs, expenses, professional fees and any other Secured Obligations; and third, after all Secured Obligations are repaid, the excess (if any) shall be refunded to Borrower.

(b) In the event any payment is not paid on the scheduled Payment Date, an amount equal to two percent (2%) of the past due amount shall be payable on demand. In addition, upon the occurrence and during the continuation of an Event of Default hereunder, all Secured Obligations, including principal, interest, compounded interest, and professional fees, shall bear interest at a rate per annum equal to the rate set forth in Section 2.2 plus five percent (5%) per annum (“Default Rate”).

All certificates of insurance will provide for a minimum of thirty (30) days advance written notice to Lender of cancellation or any other change adverse to Lender’s interests. Any failure of Lender to scrutinize such insurance certificates for compliance is not a waiver of any of Lender’s rights, all of which are reserved.

Borrower shall from time to time procure any instruments or documents as may be reasonably requested by Lender, and take all further action that may be necessary or desirable, or that Lender may reasonably request, to carry out more effectively the provisions and purposes of this Agreement or any other Loan Document or to confirm, perfect, preserve and protect the Liens granted hereby and thereby. In addition, and for such purposes only, Borrower hereby authorizes Lender to execute and deliver on behalf of Borrower and to file such financing statements, notices, control agreements, security agreements and other documents without the signature of Borrower either in Lender’s name or in the name of Lender as agent and attorney-in-fact for Borrower. The parties agree that a carbon, facsimile, photographic or other reproduction of this Agreement shall be sufficient as a financing statement and may be filed in any appropriate office in lieu thereof.

7.5. Borrower shall protect and defend Borrower’s title to the Collateral and Lender’s Lien thereon against all Persons claiming any interest adverse to Borrower or Lender, subject to Permitted Liens.

7.8. Borrower or its Subsidiaries shall not consummate any Merger (pursuant to a merger agreement which is not subject to Lender’s consent) without the prior written consent of Lender provided such consent shall not be required if Borrower elects to pay off the entire balance of the Note(s) prior to the consummation of such Merger. So long as no Event of Default has occurred and is continuing, Lender agrees not to unreasonably withhold its consent to any Merger to the extent the same does not, in Lender’s reasonable discretion, adversely affect Lender’s interests under the Loan Documents or increase the risk of non-payment or late payment of the Secured Obligations. Lender may, at its sole option, require, as a condition of any such consent, that (a) the Note(s) be paid off in their entirety prior to or simultaneously with the Merger being consummated, (b) the assets acquired in

such Merger (i) subject to the limitations on Collateral set forth in Section 3.1, be provided as Collateral (including assets of any Subsidiary of Borrower) and (ii) be free and clear of Liens (other than Permitted Liens), (c) any party to the Merger, or parent, Subsidiary or affiliate of Borrower guarantee the Secured Obligations, or (d) documents be delivered, including certificates, lien search results, financing statements and opinions, or other actions be taken so as to give Lender reasonable confidence in the ability of Borrower to satisfy the Secured Obligations on a timely basis.

Borrower shall file on or before the due date therefore all personal property tax returns in respect of the Collateral. Notwithstanding the foregoing, no tax, fee or other charge need be paid if it is being contested by Borrower in good faith and by appropriate proceedings and Borrower maintains adequate reserves therefor in accordance with GAAP.

7.12. Without 30 days prior written notice to Lender, Borrower shall not relocate its chief executive office or its principal place of business. Without 30 days prior written notice to Lender, Borrower shall not maintain any item of the Collateral (other than sale of Inventory in the ordinary course of business) at any location other than those specified in Section 5.12 of the Disclosure Letter; provided that, if such new location is outside the continental United States, Borrower shall obtain the written consent of Lender, which consent shall not be unreasonably withheld.

SECTION 11. REMEDIES

11.1. Upon the occurrence and during the continuance of any one or more Events of Default, (i) Lender’s commitment to make any Advances shall automatically expire, (ii) Lender’s obligation to permit the Loan and Secured Obligations to remain outstanding shall automatically expire, and (iii) Lender may, at its option, accelerate and demand payment of all or any part of the Secured Obligations and declare them to be immediately due and payable (provided, that upon the occurrence of an Event of Default of the type described in Sections 10.4 or 10.5, the Notes and all of the Secured Obligations shall automatically be accelerated and made due and payable, in each case without any further notice or act). Upon the occurrence and during the continuance of an Event of Default, the unpaid principal of and accrued interest on the Notes and Advances and all outstanding Secured Obligations, including all professional fees and expenses, shall thereafter bear interest at the Default Rate. Lender may exercise all rights and remedies with respect to the Collateral under the Loan Documents or otherwise available to it under the UCC and other applicable law, including the right to release, hold, sell, lease, liquidate, collect, realize upon, or otherwise dispose of all or any part of the Collateral and the right to occupy, utilize, process and commingle the Collateral. All Lender’s rights and remedies shall be cumulative and not exclusive.

11.2. Upon the occurrence and during the continuance of any Event of Default, Lender may, at any time or from time to time, apply, collect, liquidate, sell in one or more sales, lease or otherwise dispose of, any or all of the Collateral, in its then condition or following any commercially reasonable preparation or processing, in such order as Lender may elect. Any such sale may be made either at public or private sale at its place of business or elsewhere. Borrower agrees that any such public or private sale may occur upon ten (10) calendar days’ prior written notice to Borrower. Lender may require Borrower to assemble the Collateral and make it available to Lender at a place designated by Lender that is reasonably convenient to Lender and Borrower. The proceeds of any sale, disposition or other realization upon all or any part of the Collateral shall be applied by Lender in the following order of priorities:

First, to Lender in an amount sufficient to pay in full Lender’s costs and professionals’ and advisors’ fees and expenses as described in Section 12.15;

Second, to Lender in an amount equal to the then unpaid amount of the Secured Obligations (including principal, interest, and the Default Rate interest), in such order and priority as Lender may choose in its sole discretion; and

Finally, after the full, final, and indefeasible payment in Cash of all of the Secured Obligations, to any creditor holding a junior Lien on the Collateral, or to Borrower or its representatives or as a court of competent jurisdiction may direct.

Lender shall be deemed to have acted reasonably in the custody, preservation and disposition of any of the Collateral if it complies with the obligations of a secured party under the UCC.

SECTION 12. MISCELLANEOUS

12.1. Continuation of Security Interest. This is a continuing Agreement and the grant of a Lien hereunder shall remain in full force and effect and all of the rights, powers and remedies of Lender hereunder shall continue to exist until the Secured Obligations are fully, finally, and indefeasibly paid in Cash and until Lender has executed a written termination statement. Lender shall execute a termination statement within a reasonable time after the full, final, and indefeasible payment in Cash of the Secured Obligations hereunder, releasing to Borrower, without recourse, its security interest in the Collateral and all rights conveyed hereby and returning possession of the Collateral to Borrower. The rights, powers and remedies of Lender hereunder shall be in addition to all rights, powers and remedies given by statute or rule of law and are cumulative. The exercise of any one or more of the rights, powers and remedies provided herein shall not be construed as a waiver of or election of remedies with respect to any other rights, powers and remedies of Lender.

12.2. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under such law, such provision shall be ineffective only to the extent and duration of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement.

Except as otherwise provided herein, any notice, demand, request, consent, approval, declaration, service of process or other communication (including the delivery of Financial Statements) that is required, contemplated, or permitted under the Loan Documents or with respect to the subject matter hereof shall be in writing, and shall be deemed to have been validly served, given, delivered, and received upon the earlier of: (i) upon receipt if transmitted

None of the terms of this Agreement, the Notes or any of the other Loan Documents may be amended except by an instrument executed by each of the parties hereto.

12.5. Headings. The various headings in this Agreement are inserted for convenience only and shall not affect the meaning or interpretation of this Agreement or any provisions hereof.

12.6. Advice of Counsel. Each of the parties represents to each other party hereto that it has discussed (or had an opportunity to discuss) with its counsel this Agreement.

12.7. No Waiver. The powers conferred upon Lender by this Agreement are solely to protect its rights hereunder and under the other Loan Documents and its interest in the Collateral and shall not impose any duty upon Lender to exercise any such powers. No omission or delay by Lender at any time to enforce any right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by Borrower at any time designated, shall be a waiver of any such right or remedy to which Lender is entitled, nor shall it in any way affect the right of Lender to enforce such provisions thereafter.

12.8. Survival. All agreements, representations and warranties contained in this Agreement, the Notes and the other Loan Documents or in any document delivered pursuant hereto or thereto shall be for the benefit of Lender and shall survive the execution and delivery of this Agreement and the expiration or other termination of this Agreement.

12.9. Successors and Assigns. The provisions of this Agreement and the other Loan Documents shall inure to the benefit of and be binding on Borrower and its permitted assigns (if any). Borrower shall not assign its obligations under this Agreement, the Notes or any of the other Loan Documents without Lender’s express prior written consent, and any such attempted assignment shall be void and of no effect. Lender may assign, transfer, or endorse its rights hereunder and under the other Loan Documents as set forth in Section 12.17 without prior notice to Borrower, and all of such rights shall inure to the benefit of Lender’s successors and assigns.

12.10. Tax Indemnification. Borrower agrees to pay, and to save Lender harmless from, any and all liabilities with respect to, or resulting from any delay in paying, any and all excise, sales or other similar taxes (excluding taxes imposed on or measured by the net income of Lender) that may be payable or determined to be payable with respect to any of the Collateral or in connection with any of the transactions contemplated by this Agreement.

12.11. Governing Law. This Agreement, the Notes and the other Loan Documents have been negotiated and delivered to Lender in the State of California, and shall have been accepted by Lender in the State of California. Payment to Lender by Borrower of the Secured Obligations is due in the State of California. This Agreement, the Notes and the other Loan Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of California, excluding conflict of laws principles that would cause the application of laws of any other jurisdiction.

12.12. Consent to Jurisdiction and Venue. All judicial proceedings arising in or under or related to this Agreement, the Notes or any of the other Loan Documents may be brought in any state or federal court of competent jurisdiction located in the State of California. By execution and delivery of this Agreement, each party hereto generally and unconditionally: (a) consents to personal jurisdiction in San Mateo County, State of California; (b) waives any objection as to jurisdiction or venue in San Mateo County, State of California; (c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (d) irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement, the Notes or the other Loan Documents. Service of process on any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance with the requirements for notice set forth in Section 12.3, and shall be deemed effective and received as set forth in Section 12.3. Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either party to bring proceedings in the courts of any other jurisdiction.

12.13. Mutual Waiver of Jury Trial. Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF BORROWER AND LENDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY BORROWER AGAINST LENDER OR ITS ASSIGNEE OR BY LENDER OR ITS ASSIGNEE AGAINST BORROWER. This waiver extends to all such Claims, including Claims that involve Persons other than Borrower and Lender; Claims that arise out of or are in any way connected to the relationship between Borrower and Lender; and any Claims for damages, breach of contract, specific performance, or any equitable or legal relief of any kind, arising out of this Agreement, any other Loan Document or any of the Excluded Agreements.

12.14. Professional Fees. Borrower promises to pay Lender’s fees and expenses necessary to finalize the loan documentation including but not limited to attorneys fees, UCC searches, filing costs, and other miscellaneous expenses. In addition, Borrower promises to pay any and all reasonable attorneys’ and other professionals’ fees and expenses incurred by Lender after the Closing Date in connection with or related to: (a) the Loan; (b) the administration, collection, or enforcement of the Loan; (c) the amendment or modification of the Loan Agreement; (d) any waiver, consent, release, or termination under the Loan Agreement; (e) the protection, preservation, sale, lease, liquidation, or disposition of Collateral or the exercise of remedies with respect to the Collateral; (f) any legal, litigation, administrative, arbitration, or out of court proceeding in connection with or related to Borrower or the Collateral, and any appeal or review thereof; and (g) any bankruptcy, restructuring, reorganization, assignment for the benefit of creditors, workout, foreclosure, or other action related to Borrower, the Collateral, the Loan Documents, or the Excluded Agreements, including representing Lender in any adversary proceeding or contested matter commenced or continued by or on behalf of Borrower’s estate, and any appeal or review thereof. Lender’s professional fees and expenses shall include fees or expenses for Lender’s attorneys, accountants, auctioneers, liquidators, appraisers, investment advisors, environmental and management consultants, or experts engaged by Lender in connection with the foregoing. Borrower’s promise to pay all of Lender’s reasonable professional fees and expenses is part of the Secured Obligations under this Agreement. For the purposes of this Section 12.14, attorneys’ fees shall include, without limitation, fees incurred in connection with the following: (i) contempt proceedings; (ii) discovery; (iii) any motion, proceeding or other activity of any kind in connection with an insolvency proceeding; (iv) garnishment, levy, and debtor and third party examinations; and (v) post-judgment motions and proceedings of any kind, including without limitation any activity taken to collect or enforce any judgment. All of the foregoing costs and expenses shall be payable upon demand by Lender, and if not paid within thirty (30) days of presentation of invoices shall bear interest at the highest applicable Default Rate.

12.15. Revival of Secured Obligations. This Agreement and the Loan Documents shall remain in full force and effect and continue to be effective if any petition is filed by or against Borrower for liquidation or reorganization, if Borrower becomes insolvent or makes an assignment for the benefit of creditors, if a receiver or trustee is appointed for all or any significant part of Borrower’s assets, or if any payment or transfer of Collateral is recovered from Lender. The Loan Documents and the Secured Obligations and Collateral security shall continue to be effective, or shall be revived or reinstated, as the case may be, if at any time payment and performance of the Secured Obligations or any transfer of Collateral to Lender, or any part thereof is rescinded, avoided or avoidable, reduced in amount, or must otherwise be restored or

returned by, or is recovered from, Lender or by any obligee of the Secured Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment, performance, or transfer of Collateral had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, avoided, avoidable, restored, returned, or recovered, the Loan Documents and the Secured Obligations shall be deemed, without any further action or documentation, to have been revived and reinstated except to the extent of the full, final, and indefeasible payment to Lender in Cash.

12.16. Confidentiality. Lender shall hold all non-public information regarding Borrower and its business obtained by Lender pursuant to the requirements of the Loan Documents in accordance with Lender’s customary procedures for handling confidential information of a like nature, it being understood and agreed by Borrower that Lender may make (a) disclosures of such information on a need to know basis to its agents and advisors, (b) disclosure of such information reasonably required by any bona fide or potential assignee, transferee or participant in connection with the contemplated transfer, assignment, transfer or participation by Lender of any Advances; provided that prior to such disclosure, such assignee, transferee or participant agrees to be bound by the provisions of this Section 12.16; and (c) disclosures required by any governmental agency or representative thereof or pursuant to legal or judicial process; provided that, unless specifically prohibited by applicable law or court order, Lender shall make reasonable efforts to notify Borrower of any request by any governmental agency or representative thereof (other than any such request in connection with the examination of the financial condition of Lender or other routine examination of Lender by such governmental agency) for disclosure of any such non-public information prior to the disclosure of such information.

12.17. Assignments. Borrower acknowledges and understands that Lender may sell and assign all or part of its interest hereunder and under the Note(s) and Loan Documents to any person or entity (an “Assignee”). After such assignment the term “Lender” as used in the Loan Documents shall mean and include such Assignee, and such Assignee shall be vested with all rights, powers and remedies of Lender hereunder with respect to the interest so assigned; but with respect to any such interest not so transferred, Lender shall retain all rights, powers and remedies hereby given. No such assignment by Lender shall relieve Borrower of any of its obligations hereunder. Lender agrees that in the event of any transfer by it of the Note(s), it will endorse thereon a notation as to the portion of the principal of the Note(s), which shall have been paid at the time of such transfer and as to the date to which interest shall have been last paid thereon.

12.18. Agreement not to Trade. For so long as any historical or projected financial information provided by Borrower to Lender remains Undisclosed Financial Information, Lender agrees not to purchase, sell, or make any short sale of any shares of Borrower’s Common Stock, to grant, purchase, or sell any options for the purchase or sale of Borrower’s Common Stock, or otherwise to engage in any transactions in shares of Borrower’s Common Stock (whether directly or through transactions in derivative securities) that would result in any violation of the Act or any rule or regulation promulgated thereunder. “Undisclosed Financial Information” means such financial projections and any other historical or projected financial information relating to Borrower that has not been publicly disclosed by Borrower but that is disclosed, whether orally or in writing, to Lender. Undisclosed Financial Information shall cease to be Undisclosed Financial Information at such time as Borrower has publicly disclosed such information or with respect to projected financial information that is not publicly disclosed, at such time as the time periods to which such projected financial information relates have expired.

12.19. Releases of Collateral. Upon the payment in full of all Secured Obligations, the security interest granted hereby shall terminate hereunder and of record and all rights to the Collateral shall revert to Grantors. Upon any such termination Lender shall, at Grantors’ expense, execute and deliver to Grantors such documents as Grantors shall reasonably request to evidence such termination.

12.20. Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same instrument.
