NEOPHOTONICS CORPORATION

LOAN AND SECURITY AGREEMENT

This LOAN AND SECURITY AGREEMENT is entered into as of December 20, 2007, by and between Comerica Bank (“Bank”) and NeoPhotonics Corporation (“Borrower”).

RECITALS

Borrower wishes to obtain credit from time to time from Bank, and Bank desires to extend credit to Borrower. This Agreement sets forth the terms on which Bank will advance credit to Borrower, and Borrower will repay the amounts owing to Bank.

AGREEMENT

The parties agree as follows:

1. DEFINITIONS AND CONSTRUCTION.

1.1 Definitions. As used in this Agreement, all capitalized terms shall have the definitions set forth on Exhibit A. Any term used in the Code and not defined herein shall have the meaning given to the term in the Code.

1.2 Accounting Terms. Any accounting term not specifically defined on Exhibit A shall be construed in accordance with GAAP and all calculations shall be made in accordance with GAAP. The term “financial statements” shall include the accompanying notes and schedules.

2. LOAN AND TERMS OF PAYMENT.

2.1 Credit Extensions.

(a) Promise to Pay. Borrower promises to pay to Bank, in lawful money of the United States of America, the aggregate unpaid principal amount of all Credit Extensions made by Bank to Borrower, together with interest on the unpaid principal amount of such Credit Extensions at rates in accordance with the terms hereof.

(b) Advances Under Revolving Line.

(i) Amount. Subject to and upon the terms and conditions of this Agreement (1) Borrower may request Advances in an aggregate outstanding amount not to exceed the lesser of the Revolving Line (which is inclusive of amounts outstanding under the Letter of Credit Sublimit), and (2) amounts borrowed pursuant to this Section 2.1(b) may be repaid and reborrowed at any time prior to the Revolving Maturity Date, at which time all Advances under this Section 2.1(b) shall be immediately due and payable. Except as otherwise provided in the LIBOR Addendum, Borrower may prepay any Advances without penalty or premium.

(ii) Form of Request. Whenever Borrower desires an Advance, Borrower will notify Bank by facsimile transmission or telephone no later than 3:00 p.m. Pacific time (1:00 p.m. Pacific time for wire transfers), on the Business Day that the Advance is to be made. Each such notification shall be promptly confirmed by a Payment/Advance Form in substantially the form of Exhibit C. Bank is authorized to make Advances under this Agreement, based upon instructions received from a Responsible Officer or a designee of a Responsible Officer, or

without instructions if in Bank’s discretion such Advances are necessary to meet Obligations which have become due and remain unpaid. Bank shall be entitled to rely on any telephonic notice given by a person who Bank reasonably believes to be a Responsible Officer or a designee thereof, and Borrower shall indemnify and hold Bank harmless for any damages or loss suffered by Bank as a result of such reliance. Bank will credit the amount of Advances made under this Section 2.1(b) to Borrower’s deposit account.

(iii) Letter of Credit Sublimit. Subject to the availability under the Revolving Line, and in reliance on the representations and warranties of Borrower set forth herein, at any time and from time to time from the date hereof through the Business Day immediately prior to the Revolving Maturity Date, Bank shall issue for the account of Borrower such Letters of Credit as Borrower may request by delivering to Bank a duly executed letter of credit application on Bank’s standard form; provided, however, that the outstanding and undrawn amounts under all such Letters of Credit (i) shall not at any time exceed the Letter of Credit Sublimit, and (ii) shall be deemed to constitute Advances for the purpose of calculating availability under the Revolving Line. Any drawn but unreimbursed amounts under any Letters of Credit shall be charged as Advances against the Revolving Line. All Letters of Credit shall be in form and substance acceptable to Bank in its sole discretion and shall be subject to the terms and conditions of Bank’s form application and letter of credit agreement. Borrower will pay any standard issuance and other fees that Bank notifies Borrower it will charge for issuing and processing Letters of Credit. Notwithstanding anything to the contrary set forth herein, Borrower shall only request, and Bank shall only issue, Letters of Credit in favor of Standard Chartered Bank.

(iv) Collateralization of Obligations Extending Beyond Maturity. If Borrower has not secured to Bank’s satisfaction its obligations with respect to any Letters of Credit by the Revolving Maturity Date, then, effective as of such date, the balance in any deposit accounts held by Bank and the certificates of deposit or time deposit accounts issued by Bank in Borrower’s name (and any interest paid thereon or proceeds thereof, including any amounts payable upon the maturity or liquidation of such certificates or accounts), shall automatically secure such obligations to the extent of the then continuing or outstanding and undrawn Letters of Credit. Borrower authorizes Bank to hold such balances in pledge and to decline to honor any drafts thereon or any requests by Borrower or any other Person to pay or otherwise transfer any part of such balances for so long as the Letters of Credit are outstanding or continue.

2.2 Reserved.

2.3 Interest Rates, Payments, and Calculations.

(a) Interest Rates.

(i) Advances. Except as set forth in Section 2.3(b), the Advances shall bear interest, on the outstanding daily balance thereof, at either the Prime Rate Option (as defined in the LIBOR Addendum) interest rate or the LIBOR Option (as defined in the LIBOR Addendum) interest rate, as set forth in the LIBOR Addendum.

(ii) Equipment Advances. Except as set forth in Section 2.3(b), the Equipment Advances shall bear interest, on the outstanding daily balance thereof, at either the Prime Rate Option interest rate or the LIBOR Option interest rate, as set forth in the LIBOR Addendum.

4

(iii) Term Loan. Except as set forth in Section 2.3(b), the Term Loan shall bear interest, on the outstanding daily balance thereof, at either the Prime Rate Option interest rate or the LIBOR Option interest rate, as set forth in the LIBOR Addendum.

(b) Late Fee; Default Rate. If any payment is not made within 10 days after the date such payment is due, Borrower shall pay Bank a late fee equal to the lesser of (i) 5% of the amount of such unpaid amount or (ii) the maximum amount permitted to be charged under applicable law. All Obligations shall bear interest, from and after the occurrence and during the continuance of an Event of Default, at a rate equal to 5 percentage points above the interest rate applicable immediately prior to the occurrence of the Event of Default.

(c) Payments. Interest hereunder shall be due and payable (i) on the seventeenth calendar day of each month during the term hereof with respect to Credit Extensions bearing interest at the Prime Rate Option and (ii) on the last day of the applicable LIBOR Period with respect to Credit Extensions bearing interest at the LIBOR Option. Bank shall, at its option, charge such interest, all Bank Expenses, and all Periodic Payments against any of Borrower’s deposit accounts or against the Revolving Line, in which case those amounts shall thereafter accrue interest at the rate then applicable hereunder. Any interest not paid when due shall be compounded by becoming a part of the Obligations, and such interest shall thereafter accrue interest at the rate then applicable hereunder.

(d) Computation. In the event the Prime Rate is changed from time to time hereafter, the applicable rate of interest hereunder shall be increased or decreased, effective as of the day the Prime Rate is changed, by an amount equal to such change in the Prime Rate. All interest chargeable under the Loan Documents shall be computed on the basis of a 360 day year for the actual number of days elapsed.

2.4 Crediting Payments. Prior to the occurrence of an Event of Default, Bank shall credit a wire transfer of funds, check or other item of payment to such deposit account or Obligation as Borrower specifies, except that to the extent Borrower uses the Advances to purchase Collateral, Borrower’s repayment of the Advances shall apply on a “first-in-first-out” basis so that the portion of the Advances used to purchase a particular item of Collateral shall be paid in the chronological order the Borrower purchased the Collateral. After the occurrence of an Event of Default, Bank shall have the right, in its sole discretion, to immediately apply any wire transfer of funds, check, or other item of payment Bank may receive to conditionally reduce Obligations, but such applications of funds shall not be considered a payment on account unless such payment is of immediately available federal funds or unless and until such check or other item of payment is honored when presented for payment. Notwithstanding anything to the contrary contained herein, any wire transfer or payment received by Bank after 12:00 noon Pacific time shall be deemed to have been received by Bank as of the opening of business on the immediately following Business Day. Whenever any payment to Bank under the Loan Documents would otherwise be due (except by reason of acceleration) on a date that is not a Business Day, such payment shall instead be due on the next Business Day, and additional fees or interest, as the case may be, shall accrue and be payable for the period of such extension.

2.5 Fees. Borrower shall pay to Bank the following:

(a) Facility Fee. (i) On the Closing Date and each anniversary of the Closing Date, a fee equal to $19,500 with respect to the Revolving Line and (ii) on the Closing Date $25,500 with respect to the Equipment Line, all of which fees shall be nonrefundable; and

(b) Bank Expenses. (i) On the Closing Date, all Bank Expenses incurred through the Closing Date; provided, however, that Borrower’s obligation to reimburse Bank for legal fees shall be limited to $11,000 so long as there is only one turn of the Loan Documents based on comments received from Borrower or any third party, and, (ii) after the Closing Date, all Bank Expenses, as and when they become due.

5

2.6 Term. This Agreement shall become effective on the Closing Date and, subject to Section 13.7, shall continue in full force and effect for so long as any Obligations remain outstanding or Bank has any obligation to make Credit Extensions under this Agreement. Notwithstanding the foregoing, Bank shall have the right to terminate its obligation to make Credit Extensions under this Agreement immediately and without notice upon the occurrence and during the continuance of an Event of Default.

3. CONDITIONS OF LOANS.

The making of each Credit Extension shall be deemed to be a representation and warranty by Borrower on the date of such Credit Extension as to the accuracy of the facts referred to in this Section 3.2.

4. CREATION OF SECURITY INTEREST.

4.1 Grant of Security Interest. Borrower grants and pledges to Bank a continuing security interest in the Collateral to secure prompt repayment of any and all Obligations and to secure prompt performance by Borrower of each of its covenants and duties under the Loan Documents. Except as set forth in the Schedule, such security interest constitutes a valid, first priority security interest in the presently existing Collateral, and will constitute a valid, first priority security interest in later-acquired Collateral. Borrower also hereby agrees to not sell, transfer, assign, mortgage, pledge, lease, grant a security interest in, or encumber any of its Intellectual Property. Notwithstanding any termination, Bank’s Lien on the Collateral shall remain in effect for so long as any Obligations are outstanding.

4.2 Perfection of Security Interest. Borrower authorizes Bank to file at any time financing statements, continuation statements, and amendments thereto that (i) either specifically describe the Collateral or describe the Collateral as all assets of Borrower of the kind pledged hereunder, and (ii) contain any other information required by the Code for the sufficiency of filing office acceptance of any financing statement, continuation statement, or amendment, including whether Borrower is an organization, the type of organization and any organizational identification number issued to Borrower, if applicable. Any such financing statements may be signed by Bank on behalf of Borrower, as provided in the Code, and may be filed at any time in any jurisdiction whether or not Revised Article 9 of the Code is then in effect in that jurisdiction. Borrower shall from time to time endorse and deliver to Bank, at the request of Bank, all Negotiable Collateral and other documents that Bank may reasonably request, in form satisfactory to Bank, to perfect and continue perfected Bank’s security interests in the Collateral and in order to fully consummate all of the transactions contemplated under the Loan Documents. Borrower shall have possession of the Collateral, except where expressly otherwise provided in this Agreement or where Bank chooses to perfect its security interest by possession in addition to the filing of a financing statement. Where Collateral is in possession of a third party bailee, Borrower shall take such steps as Bank reasonably requests for Bank to (i) obtain an acknowledgment, in form and substance satisfactory to Bank, of the bailee that the bailee holds such Collateral for the benefit of Bank, or (ii) obtain “control” of any Collateral consisting of investment property, deposit accounts, letter-of-credit

7

rights or electronic chattel paper (as such items and the term “control” are defined in Revised Article 9 of the Code) by causing the securities intermediary or depositary institution or issuing bank to execute a control agreement in form and substance satisfactory to Bank. Borrower will not create any chattel paper without placing a legend on the chattel paper acceptable to Bank indicating that Bank has a security interest in the chattel paper. Borrower from time to time may deposit with Bank specific cash collateral to secure specific Obligations; Borrower authorizes Bank to hold such specific balances in pledge and to decline to honor any drafts thereon or any request by Borrower or any other Person to pay or otherwise transfer any part of such balances for so long as the specific Obligations are outstanding.

4.3 Right to Inspect. Bank (through any of its officers, employees, or agents) shall have the right, upon reasonable prior notice, from time to time during Borrower’s usual business hours but no more than twice a year at Borrower’s expense, which expense shall not exceed $4,000 per year (unless an Event of Default has occurred and is continuing), to inspect Borrower’s Books and to make copies thereof and to check, test, and appraise the Collateral in order to verify Borrower’s financial condition or the amount, condition of, or any other matter relating to, the Collateral.

4.4 Shares. Borrower hereby pledges, assigns and grants to Bank a security interest in all the Shares, together with all proceeds and substitutions thereof, all cash, stock and other moneys and property paid thereon, all rights to subscribe for securities declared or granted in connection therewith, and all other cash and noncash proceeds of the foregoing, as security for the performance of the Obligations. The certificate or certificates for the Shares, if any, will be delivered to Bank upon the Closing Date, accompanied by an instrument of assignment duly executed in blank by Borrower. Borrower will promptly, and in any event within five (5) days of issuance, deliver to Bank any certificate or certificates at any time issued after the Closing Date representing any Shares, accompanied by an instrument of assignment duly executed in blank by Borrower. To the extent required by the terms and conditions governing the Shares, Borrower shall cause the books of each entity whose Shares are part of the Collateral and any transfer agent to reflect the pledge of the Shares. Upon the occurrence and during the continuance of an Event of Default hereunder, Bank may effect the transfer of any securities included in the Collateral into the name of Bank and cause new certificates representing such securities to be issued in the name of Bank or its transferee. Borrower will execute and deliver such documents, and take or cause to be taken such actions, as Bank may reasonably request to perfect or continue the perfection of Bank’s security interest in the Shares and securities constituting Collateral. Unless an Event of Default shall have occurred and be continuing, Borrower shall be entitled to exercise any voting rights with respect to the Shares or other securities and to give consents, waivers and ratifications in respect thereof, provided that no vote shall be cast or consent, waiver or ratification given or action taken which would be inconsistent with any of the terms of this Agreement or which would constitute or create any violation of any of such terms. All such rights to vote and give consents, waivers and ratifications shall terminate upon the occurrence and continuance of an Event of Default.

5. REPRESENTATIONS AND WARRANTIES.

Except as set forth on the Schedule, Borrower represents and warrants as follows:

5.1 Due Organization and Qualification. Borrower and each Subsidiary is a corporation duly existing under the laws of the state or jurisdiction in which it is incorporated and qualified and licensed to do business in any state or jurisdiction in which the conduct of its business or its ownership of property requires that it be so qualified, except where the failure to do so would not reasonably be expected to cause a Material Adverse Effect.

5.2 Due Authorization; No Conflict. The execution, delivery, and performance of the Loan Documents are within Borrower’s powers, have been duly authorized, and are not in conflict with nor constitute a breach of any provision contained in Borrower’s Certificate of Incorporation or Bylaws, nor will they constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement by which it is bound, except to the extent such default would not reasonably be expected to cause a Material Adverse Effect.

8

5.3 Collateral. Borrower has rights in or the power to transfer the Collateral, and its title to the Collateral is free and clear of Liens, adverse claims, and restrictions on transfer or pledge except for Permitted Liens. All Collateral is located solely in the Collateral States. All Inventory is in all material respects of good and merchantable quality, free from all material defects, except for Inventory for which adequate reserves have been made. Except as set forth in the Schedule, none of the Collateral is maintained or invested with a Person other than Bank or Bank’s Affiliates.

5.4 Intellectual Property. Borrower is the sole owner of the Intellectual Property, except for licenses granted by Borrower to its customers in the ordinary course of business. To the best of Borrower’s knowledge, each of the Copyrights, Trademarks and Patents is valid and enforceable, and no part of the Intellectual Property has been judged invalid or unenforceable, in whole or in part, and no claim has been made to Borrower that any part of the Intellectual Property violates the rights of any third party except to the extent such claim would not reasonably be expected to cause a Material Adverse Effect.

5.5 Name; Location of Chief Executive Office. Except as disclosed in the Schedule, Borrower has not done business under any name other than that specified on the signature page hereof, and its exact legal name is as set forth in the first paragraph of this Agreement. The chief executive office of Borrower is located in the Chief Executive Office State at the address indicated in Section 10 hereof.

5.6 Litigation. Except as set forth in the Schedule, there are no actions or proceedings pending by or against Borrower or any Subsidiary before any court or administrative agency in which a likely adverse decision would reasonably be expected to have a Material Adverse Effect.

5.7 No Material Adverse Change in Financial Statements. All consolidated and consolidating financial statements related to Borrower and any Subsidiary that are delivered by Borrower to Bank fairly present in all material respects Borrower’s consolidated and consolidating financial condition as of the date thereof and Borrower’s consolidated and consolidating results of operations for the period then ended. There has not been a material adverse change in the consolidated or in the consolidating financial condition of Borrower since the date of the most recent of such financial statements submitted to Bank.

5.8 Solvency, Payment of Debts. Borrower is able to pay its debts (including trade debts) as they mature; the fair saleable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; and Borrower is not left with unreasonably small capital after the transactions contemplated by this Agreement.

5.9 Compliance with Laws and Regulations. Borrower and each Subsidiary have met the minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. No event has occurred resulting from Borrower’s failure to comply with ERISA that is reasonably likely to result in Borrower’s incurring any liability that could have a Material Adverse Effect. Borrower is not an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940. Borrower is not engaged principally, or as one of the important activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulations T and U of the Board of Governors of the Federal Reserve System). Borrower has complied in all material respects with all the provisions of the Federal Fair Labor Standards Act. Borrower is in compliance with all environmental laws, regulations and ordinances except where the failure to comply is not reasonably likely to have a Material Adverse Effect. Borrower has not violated any statutes, laws, ordinances or rules applicable to it, the violation of which would reasonably be expected to have a Material Adverse Effect. Borrower and each Subsidiary have filed or caused to be filed all tax

9

returns required to be filed, and have paid, or have made adequate provision for the payment of, all taxes reflected therein except those being contested in good faith with adequate reserves under GAAP or where the failure to file such returns or pay such taxes would not reasonably be expected to have a Material Adverse Effect.

5.10 Subsidiaries. Borrower does not own any stock, partnership interest or other equity securities of any Person, except for Permitted Investments and except as listed on the Schedule.

5.11 Government Consents. Borrower and each Subsidiary have obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all governmental authorities that are necessary for the continued operation of Borrower’s business as currently conducted, except where the failure to do so would not reasonably be expected to cause a Material Adverse Effect.

5.12 Inbound Licenses. Except as disclosed on the Schedule, Borrower is not a party to, nor is bound by, any license or other agreement that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement or any other property.

5.13 Shares. Borrower has full power and authority to create a first lien on the Shares and no disability or contractual obligation exists that would prohibit Borrower from pledging the Shares pursuant to this Agreement. There are no subscriptions, warrants, rights of first refusal or other restrictions on, or options exercisable with respect to the Shares. The Shares have been and will be duly authorized and validly issued, and are fully paid and non-assessable. To the best of Borrower’s knowledge, the Shares are not the subject of any present or threatened suit, action, arbitration, administrative or other proceeding, and Borrower knows of no reasonable grounds for the institution of any such proceedings.

5.14 Full Disclosure. No representation, warranty or other statement made by Borrower in any certificate or written statement furnished to Bank taken together with all such certificates and written statements furnished to Bank contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained in such certificates or statements not misleading, it being recognized by Bank that the projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are not to be viewed as facts and that actual results during the period or periods covered by any such projections and forecasts may differ from the projected or forecasted results.

6. AFFIRMATIVE COVENANTS.

Borrower covenants that, until payment in full of all outstanding Obligations, and for so long as Bank may have any commitment to make a Credit Extension hereunder, Borrower shall do all of the following:

6.1 Good Standing and Government Compliance. Borrower shall maintain its and each of its Subsidiaries’ corporate existence and good standing in the Borrower State (or with respect to any Subsidiary not organized in the Borrower State, such state or jurisdiction in which such Subsidiary is organized), shall maintain qualification and good standing in each other jurisdiction in which the failure to so qualify would reasonably be expected to have a Material Adverse Effect, and shall furnish to Bank the organizational identification number issued to Borrower by the authorities of the state in which Borrower is organized, if applicable. Borrower shall meet, and shall cause each Subsidiary to meet, the minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. Borrower shall comply in all material respects with all applicable Environmental Laws, and maintain all material permits, licenses and approvals required thereunder where the failure to do so would reasonably be expected to have a Material Adverse Effect. Borrower shall comply, and shall cause each Subsidiary to comply, with all statutes, laws, ordinances and government rules and regulations to which it is subject, and shall maintain, and shall cause each of its Subsidiaries to maintain, in force all licenses, approvals and agreements, the loss of which or failure to comply with which would reasonably be expected to have a Material Adverse Effect.

7.4 Indebtedness. Create, incur, assume, guarantee or be or remain liable with respect to any Indebtedness, or permit any Subsidiary so to do, other than Permitted Indebtedness, or prepay any Indebtedness or take any actions which impose on Borrower an obligation to prepay any Indebtedness, except Indebtedness to Bank.

7.8 Transactions with Affiliates. Directly or indirectly enter into or permit to exist any material transaction with any Affiliate of Borrower except for transactions that are in the ordinary course of Borrower’s business, upon fair and reasonable terms that are no less favorable to Borrower than would be obtained in an arm’s length transaction with a non-affiliated Person or are otherwise approved by a majority of the disinterested members of the Board of Directors.

14

7.9 Subordinated Debt. Make any payment in respect of any Subordinated Debt, or permit any of its Subsidiaries to make any such payment, except in compliance with the terms of such Subordinated Debt, or amend any provision affecting Bank’s rights contained in any documentation relating to the Subordinated Debt without Bank’s prior written consent.

8.6 Insolvency. If Borrower or any Subsidiary becomes insolvent, or if an Insolvency Proceeding is commenced by Borrower or any Subsidiary, or if an Insolvency Proceeding is commenced against Borrower or any Subsidiary and is not dismissed or stayed within 30 days (provided that no Credit Extensions will be made prior to the dismissal of such Insolvency Proceeding);

9. BANK’S RIGHTS AND REMEDIES.

9.1 Rights and Remedies. Upon the occurrence and during the continuance of an Event of Default, Bank may, at its election, without notice of its election and without demand, do any one or more of the following, all of which are authorized by Borrower:

(a) Declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and payable (provided that upon the occurrence of an Event of Default described in Section 8.6 (insolvency), all Obligations shall become immediately due and payable without any action by Bank);

(b) Demand that Borrower (i) deposit cash with Bank in an amount equal to the amount of any Letters of Credit remaining undrawn, as collateral security for the repayment of any future drawings under such Letters of Credit, and (ii) pay in advance all Letter of Credit fees scheduled to be paid or payable over the remaining term of the Letters of Credit, and Borrower shall promptly deposit and pay such amounts;

(c) Cease advancing money or extending credit to or for the benefit of Borrower under this Agreement or under any other agreement between Borrower and Bank;

(d) Settle or adjust disputes and claims directly with account debtors for amounts, upon terms and in whatever order that Bank reasonably considers advisable;

(e) Make such payments and do such acts as Bank considers necessary or reasonable to protect its security interest in the Collateral. Borrower agrees to assemble the Collateral if Bank so requires, and to make the Collateral available to Bank as Bank may designate. Borrower authorizes Bank to enter the premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any encumbrance, charge, or lien which in Bank’s determination appears to be prior or superior to its security interest and to pay all expenses incurred in connection therewith. With respect to any of Borrower’s owned premises, Borrower hereby grants Bank a license to enter into possession of such premises and to occupy the same, without charge, in order to exercise any of Bank’s rights or remedies provided herein, at law, in equity, or otherwise;

(f) Set off and apply to the Obligations any and all (i) balances and deposits of Borrower held by Bank, and (ii) indebtedness at any time owing to or for the credit or the account of Borrower held by Bank;

(g) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Collateral. Bank is hereby granted a license or other right, solely pursuant to the provisions of this Section 9.1, to use, without charge, Borrower’s labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any property of a similar nature, as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section 9.1, Borrower’s rights under all licenses and all franchise agreements shall inure to Bank’s benefit;

(h) Sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including Borrower’s premises) as Bank determines is commercially reasonable, and apply any proceeds to the Obligations in whatever manner or order Bank deems appropriate. Bank may sell the Collateral without giving any warranties as to the Collateral. Bank may specifically disclaim any warranties of title or the like. This procedure will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral. If Bank sells any of the Collateral upon credit, Borrower will

17

be credited only with payments actually made by the purchaser, received by Bank, and applied to the indebtedness of the purchaser. If the purchaser fails to pay for the Collateral, Bank may resell the Collateral and Borrower shall be credited with the proceeds of the sale;

(i) Bank may credit bid and purchase at any public sale;

(j) Apply for the appointment of a receiver, trustee, liquidator or conservator of the Collateral, without notice and without regard to the adequacy of the security for the Obligations and without regard to the solvency of Borrower, any guarantor or any other Person liable for any of the Obligations; and

(k) Any deficiency that exists after disposition of the Collateral as provided above will be paid immediately by Borrower.

Bank may comply with any applicable state or federal law requirements in connection with a disposition of the Collateral and compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral.

9.2 Power of Attorney. Effective only upon the occurrence and during the continuance of an Event of Default, Borrower hereby irrevocably appoints Bank (and any of Bank’s designated officers, or employees) as Borrower’s true and lawful attorney to: (a) send requests for verification of Accounts or notify account debtors of Bank’s security interest in the Accounts; (b) endorse Borrower’s name on any checks or other forms of payment or security that may come into Bank’s possession; (c) sign Borrower’s name on any invoice or ▇▇▇▇ of lading relating to any Account, drafts against account debtors, schedules and assignments of Accounts, verifications of Accounts, and notices to account debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all claims under and decisions with respect to Borrower’s policies of insurance; (f) settle and adjust disputes and claims respecting the accounts directly with account debtors, for amounts and upon terms which Bank determines to be reasonable; (g) enter into a short-form intellectual property security agreement consistent with the terms of this Agreement for recording purposes only or modify, in its sole discretion, any intellectual property security agreement entered into between Borrower and Bank without first obtaining Borrower’s approval of or signature to such modification by amending Exhibits A, B, and C, thereof, as appropriate, to include reference to any right, title or interest in any Copyrights, Patents or Trademarks acquired by Borrower after the execution hereof or to delete any reference to any right, title or interest in any Copyrights, Patents or Trademarks in which Borrower no longer has or claims to have any right, title or interest; and (h) file, in its sole discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral without the signature of Borrower where permitted by law; provided Bank may exercise such power of attorney to sign the name of Borrower on any of the documents described in clauses (g) and (h) above, regardless of whether an Event of Default has occurred. The appointment of Bank as Borrower’s attorney in fact, and each and every one of Bank’s rights and powers, being coupled with an interest, is irrevocable until all of the Obligations have been fully repaid and performed and Bank’s obligation to provide advances hereunder is terminated.

9.3 Accounts Collection. At any time after the occurrence and during the continuation of an Event of Default, Bank may notify any Person owing funds to Borrower of Bank’s security interest in such funds and verify the amount of such Account. Borrower shall collect all amounts owing to Borrower for Bank, receive in trust all payments as Bank’s trustee, and immediately deliver such payments to Bank in their original form as received from the account debtor, with proper endorsements for deposit.

9.4 Bank Expenses. If Borrower fails to pay any amounts or furnish any required proof of payment due to third persons or entities, as required under the terms of this Agreement, then Bank may do any or all of the following after reasonable notice to Borrower: (a) make payment of the same or

18

any part thereof; (b) set up such reserves under the Revolving Line as Bank deems necessary to protect Bank from the exposure created by such failure; or (c) obtain and maintain insurance policies of the type discussed in Section 6.5 of this Agreement, and take any action with respect to such policies as Bank deems prudent. Any amounts so paid or deposited by Bank shall constitute Bank Expenses, shall be immediately due and payable, and shall bear interest at the then applicable rate hereinabove provided, and shall be secured by the Collateral. Any payments made by Bank shall not constitute an agreement by Bank to make similar payments in the future or a waiver by Bank of any Event of Default under this Agreement.

9.5 Bank’s Liability for Collateral. Bank has no obligation to clean up or otherwise prepare the Collateral for sale. All risk of loss, damage or destruction of the Collateral shall be borne by Borrower.

9.6 No Obligation to Pursue Others. Bank has no obligation to attempt to satisfy the Obligations by collecting them from any other person liable for them and Bank may release, modify or waive any collateral provided by any other Person to secure any of the Obligations, all without affecting Bank’s rights against Borrower. Borrower waives any right it may have to require Bank to pursue any other Person for any of the Obligations.

9.7 Remedies Cumulative. Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative. Bank shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Bank of one right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on Borrower’s part shall be deemed a continuing waiver. No delay by Bank shall constitute a waiver, election, or acquiescence by it. No waiver by Bank shall be effective unless made in a written document signed on behalf of Bank and then shall be effective only in the specific instance and for the specific purpose for which it was given. Borrower expressly agrees that this Section 9.7 may not be waived or modified by Bank by course of performance, conduct, estoppel or otherwise.

9.8 Demand; Protest. Except as otherwise provided in this Agreement, Borrower waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment and any other notices relating to the Obligations.

10. NOTICES.

Unless otherwise provided in this Agreement, all notices or demands by any party relating to this Agreement or any other agreement entered into in connection herewith shall be in writing and (except for financial statements and other informational documents which may be sent by first-class mail, postage prepaid) shall be personally delivered or sent by a recognized overnight delivery service, certified mail, postage prepaid, return receipt requested, or by telefacsimile to Borrower or to Bank, as the case may be, at its addresses set forth below:

11. CHOICE OF LAW AND VENUE: JURY TRIAL WAIVER.

This Agreement shall be governed by, and construed in accordance with, the internal laws of the State of California, without regard to principles of conflicts of law. Each of Borrower and Bank hereby submits to the exclusive jurisdiction of the state and Federal courts located in the County of Santa ▇▇▇▇▇, State of California. THE UNDERSIGNED ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED UNDER CERTAIN CIRCUMSTANCES. TO THE EXTENT PERMITTED BY LAW, EACH PARTY, AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY OTHER DOCUMENT, INSTRUMENT OR AGREEMENT BETWEEN THE UNDERSIGNED PARTIES.

(a) In the event the Jury Trial Waiver set forth above is not enforceable, the parties elect to proceed under this Judicial Reference Provision.

(b) With the exception of the items specified in clause (c), below, any controversy, dispute or claim (each, a “Claim”) between the parties arising out of or relating to this Agreement or any other document, instrument or agreement between the undersigned parties (collectively in this Section, the “Comerica Documents), will be resolved by a reference proceeding in California in accordance with the provisions of Sections 638 et seq. of the California Code of Civil Procedure (“CCP”), or their successor sections, which shall constitute the exclusive remedy for the resolution of any Claim, including whether the Claim is subject to the reference proceeding. Except as otherwise provided in the Comerica Documents, venue for the reference proceeding will be in the state or federal court in the county or district where the real property involved in the action, if any, is located or in the state or federal court in the county or district where venue is otherwise appropriate under applicable law (the “Court”).

(c) The matters that shall not be subject to a reference are the following: (i) nonjudicial foreclosure of any security interests in real or personal property, (ii) exercise of self-help remedies (including, without limitation, set-off), (iii) appointment of a receiver and (iv) temporary, provisional or ancillary remedies (including, without limitation, writs of attachment, writs of possession, temporary restraining orders or preliminary injunctions). This reference provision does not limit the right of any party to exercise or oppose any of the rights and remedies described in clauses (i) and (ii) or to seek or oppose from a court of competent jurisdiction any of the items described in clauses (iii) and (iv). The exercise of, or opposition to, any of those items does not waive the right of any party to a reference pursuant to this reference provision as provided herein.

(d) The referee shall be a retired judge or justice selected by mutual written agreement of the parties. If the parties do not agree within ten (10) days of a written request to do so by any party, then, upon request of any party, the referee shall be selected by the Presiding

20

Judge of the Court (or his or her representative). A request for appointment of a referee may be heard on an ex parte or expedited basis, and the parties agree that irreparable harm would result if ex parte relief is not granted. Pursuant to CCP § 170.6, each party shall have one peremptory challenge to the referee selected by the Presiding Judge of the Court (or his or her representative).

(e) The parties agree that time is of the essence in conducting the reference proceedings. Accordingly, the referee shall be requested, subject to change in the time periods specified herein for good cause shown, to (i) set the matter for a status and trial-setting conference within fifteen (15) days after the date of selection of the referee, (ii) if practicable, try all issues of law or fact within one hundred twenty (120) days after the date of the conference and (iii) report a statement of decision within twenty (20) days after the matter has been submitted for decision.

(f) The referee will have power to expand or limit the amount and duration of discovery. The referee may set or extend discovery deadlines or cutoffs for good cause, including a party’s failure to provide requested discovery for any reason whatsoever. Unless otherwise ordered based upon good cause shown, no party shall be entitled to “priority” in conducting discovery, depositions may be taken by either party upon seven (7) days written notice, and all other discovery shall be responded to within fifteen (15) days after service. All disputes relating to discovery which cannot be resolved by the parties shall be submitted to the referee whose decision shall be final and binding.

(g) Except as expressly set forth herein, the referee shall determine the manner in which the reference proceeding is conducted including the time and place of hearings, the order of presentation of evidence, and all other questions that arise with respect to the course of the reference proceeding. All proceedings and hearings conducted before the referee, except for trial, shall be conducted without a court reporter, except that when any party so requests, a court reporter will be used at any hearing conducted before the referee, and the referee will be provided a courtesy copy of the transcript. The party making such a request shall have the obligation to arrange for and pay the court reporter. Subject to the referee’s power to award costs to the prevailing party, the parties will equally share the cost of the referee and the court reporter at trial.

(h) The referee shall be required to determine all issues in accordance with existing case law and the statutory laws of the State of California. The rules of evidence applicable to proceedings at law in the State of California will be applicable to the reference proceeding. The referee shall be empowered to enter equitable as well as legal relief, enter equitable orders that will be binding on the parties and rule on any motion which would be authorized in a court proceeding, including without limitation motions for summary judgment or summary adjudication. The referee shall issue a decision at the close of the reference proceeding which disposes of all claims of the parties that are the subject of the reference. Pursuant to CCP § 644, such decision shall be entered by the Court as a judgment or an order in the same manner as if the action had been tried by the Court and any such decision will be final, binding and conclusive. The parties reserve the right to appeal from the final judgment or order or from any appealable decision or order entered by the referee. The parties reserve the right to findings of fact, conclusions of laws, a written statement of decision, and the right to move for a new trial or a different judgment, which new trial, if granted, is also to be a reference proceeding under this provision.

(i) If the enabling legislation which provides for appointment of a referee is repealed (and no successor statute is enacted), any dispute between the parties that would otherwise be determined by reference procedure will be resolved and determined by arbitration. The arbitration will be conducted by a retired judge or justice, in accordance with the California Arbitration Act § 1280 through § 1294.2 of the CCP as amended from time to time. The limitations with respect to discovery set forth above shall apply to any such arbitration proceeding.

21

(j) THE PARTIES RECOGNIZE AND AGREE THAT ALL CONTROVERSIES, DISPUTES AND CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A REFEREE AND NOT BY A JURY. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF ITS OWN CHOICE, EACH PARTY KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, AGREES THAT THIS REFERENCE PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN OR AMONG THEM ARISING OUT OF OR IN ANY WAY RELATED TO, THIS AGREEMENT OR THE OTHER COMERICA DOCUMENTS.

If Borrower does not immediately accept the rate quoted by Bank, any subsequent acceptance by Borrower shall be subject to a redetermination of the rate by Bank; provided, however, that if Borrower fails to accept any such quotation given, then the quoted rate shall expire and Bank shall have no obligation to permit a LIBOR Option to be selected on such day. If no specific designation of interest is made at the time any Advance is requested under the Note or at the end of any LIBOR Period, Borrower shall be deemed to have selected the Prime Rate Option for such Advance or the principal amount to which such LIBOR Period applied. At any time the LIBOR Option is in effect, Borrower may, at the end of the applicable LIBOR Period, convert to the Prime Rate Option. At any time the Prime Rate Option is in effect, Borrower may convert to the LIBOR OPTION, and shall designate a LIBOR Period.

7. Default Interest Rate. Upon the occurrence of a Default under the Note, the outstanding principal balance of the Note shall bear interest at the default rate set forth in the Note.

8. Prepayment. In the event that the LIBOR Option is the applicable interest rate for all or any part of the outstanding principal balance of the Note, and any payment or prepayment of any such outstanding principal balance of the Note shall occur on any day other than the last day of the applicable LIBOR Period (whether voluntarily, by acceleration, required payment, or otherwise), or if Borrower elects the LIBOR Option as the applicable interest rate for all or any part of the outstanding principal balance of the Note in accordance with the terms and conditions hereof, and, subsequent to such election, but prior to the commencement of the applicable LIBOR Period, Borrower revokes such election for any reason whatsoever, or if the applicable interest rate in respect of any outstanding principal balance of the

Note hereunder shall be changed, for any reason whatsoever, from the LIBOR Option to the Prime Rate Option prior to the last day of the applicable LIBOR Period, or if Borrower shall fail to make any payment of principal or interest hereunder at any time that the L1BOR Option is the applicable interest rate hereunder in respect of such outstanding principal balance of the Note, Borrower shall reimburse Bank, on demand, for any resulting loss, cost or expense incurred by Bank as a result thereof, including, without limitation, any such loss, cost or expense incurred in obtaining, liquidating, employing or redeploying deposits from third parties. Such amount payable by Borrower to Bank may include, without limitation, an amount equal to the excess, if any, of (a) the amount of interest which would have accrued on the amount so prepaid, or not so borrowed, refunded or converted, for the period from the date of such prepayment or of such failure to borrow, refund or convert, through the last day of the relevant LIBOR Period, at the applicable rate of interest for such outstanding principal balance of the Note, as provided under this Note, over (b) the amount of interest (as reasonably determined by Bank) which would have accrued to Bank on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank L1BOR market. Calculation of any amounts payable to Bank under this paragraph shall be made as though Bank shall have actually funded or committed to fund the relevant outstanding principal balance of the Not~ hereunder through the purchase of an underlying deposit in an amount equal to the amount of such outstanding principal balance of the Note and having a maturity comparable to the relevant LIBOR Period; provided, however, that Bank may fund the outstanding principal balance of the Note hereunder in any manner it deems fit and the foregoing assumptions shall be utilized only for the purpose of the calculation of amounts payable under this paragraph. Upon the written request of Borrower, Bank shall deliver to Borrower a certificate setting forth the basis for determining such losses, costs and expenses, which certificate shall be conclusively presumed correct, absent manifest error. Any prepayment hereunder shall also be accompanied by the payment of all accrued and unpaid interest on the amount so prepaid. Any outstanding principal balance of the Note which is bearing interest at such time at the Prime Rate Option may be prepaid without penalty or premium. Partial prepayments hereunder shall be applied to the installments hereunder in the inverse order of their maturities.

BY INITIALING BELOW, BORROWER ACKNOWLEDGE(S) AND AGREE(S) THAT: (A) THERE IS NO RIGHT TO PREPAY ANY L1BOR OPTION ADVANCE, IN WHOLE OR IN PART, WITHOUT PAYING THE PREPAYMENT AMOUNT SET FORTH HEREIN (“PREPAYMENT AMOUNT’), EXCEPT AS OTHERWISE REQUIRED UNDER APPLICABLE LAW; (B) BORROWER SHALL BE LIABLE FOR PAYMENT OF THE PREPAYMENT AMOUNT IF BANK EXERCISES ITS RIGHT TO ACCELERATE PAYMENT OF ANY LIBOR OPTION ADVANCE AS PART OR ALL OF THE OBLIGATIONS OWING UNDER THE NOTE, INCLUDING WITHOUT LIMITATION, ACCELERATION UNDER A DUE-CN-SALE PROVISION; (C) BORROWER WAIVES ANY RIGHTS UNDER SECTION 2954.10 OF THE CALIFORNIA CIVIL CODE OR ANY SUCCESSOR STATUTE; AND (D) BANK HAS MADE EACH L1BOR OPTION DVANCE PURSUANT TO THE NOTE IN RELIANCE ON THESE AGREEMENTS.

/s/ TJ

BORROWER’S INITIALS

9. Hold Harmless and Indemnification. Borrower agrees to indemnify Bank and to hold Bank harmless from, and to reimburse Bank on demand for, all losses and expenses which Bank sustains or incurs as’ a result of (i) any payment of a LIBOR Option Advance prior to the last day of the applicable LIBOR Period for any reason, including, without limitation, termination of the Note, whether pursuant to this Addendum or the occurrence of a Default under the Note; (ii) any termination of a LIBOR Period prior to the date it would otherwise end in accordance with this Addendum; or (iii) any failure by Borrower, for any reason, to borrow any portion of a LIBOR Option Advance.

10. Funding Losses. The indemnification and hold harmless provisions set forth in this Addendum shall include, without limitation, all losses and expenses arising from interest and fees that Bank pays to lenders of funds it obtains in order to fund the loans to Borrower on the basis of the LIBOR Option(s) and all losses incurred in liquidating or re-deploying deposits from which such funds were obtained and loss of profit for the period after termination. A written statement by Bank to Borrower of such losses and expenses shall be conclusive and binding, absent manifest error, for all purposes. This obligation shall survive the termination of this Addendum and the payment of the Note.

11. Regulatory Developments Or Other Circumstances Relating To Illegality or Impracticality of LIBOR. If any Regulatory Development or other circumstances relating to the interbank Euro-dollar markets shall, at any time. in Bank’s reasonable determination, make it unlawful or impractical for Bank to fund or maintain, during any LIBOR Period, to determine or charge interest rates based upon USOR, Bank shall give notice of such circumstances to Borrower and:

(i) In the case of a LIBOR Period in progress, Borrower shall, if requested by Bank, promptly pay any interest which had accrued prior to such request and the date of such request shall be deemed to be the last day of the term of the LIBOR Period; and

(ii) No LIBOR Period may be designated thereafter until Bank determines that such would be practical.

12. Additional Costs. Borrower shall pay to Bank from time to time, upon Bank’s request, such amounts as Bank determines are needed to compensate Bank for any costs it incurred which are attributable to Bank having made or maintained a LIBOR Option Advance or to Bank’s obligation to make a LIBOR Option Advance, or any reduction in any amount receivable by Bank hereunder with respect to any USOR Option or such obligation (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), resulting from any Regulatory Developments, which (i) change the basis of taxation of any amounts payable to Bank hereunder with respect to taxation of any amounts payable to Bank hereunder with respect to any USOR Option Advance (other than taxes imposed on the overall net income of Bank for any LIBOR Option Advance by the jurisdiction where Bank is headquartered or the jurisdiction where Bank extends the LIBOR Option Advance; (ii) impose or modify any reserve, special deposit, or similar requirements relating to any extensions of credit or other assets of, or any deposits with or other liabilities of, Bank (including any LIBOR Option Advance or any deposits· referred to in the definition of LIBOR); or (iii) impose any other condition affecting this Addendum (or any of such extension of credit or liabilities). Bank shall notify Borrower of any event occurring after the date hereof which entitles Bank to compensation pursuant to this paragraph as promptly as practicable after it obtains knowledge thereof and determines to request such compensation. Determinations by Bank for purposes of this paragraph, shall be conclusive, provided that such determination$ are made on a reasonable basis.

13. Legal Effect. Except as specifically modified hereby, all of the terms and conditions of the Note remain in full force and effect.

IN WITNESS WHEREOF, the parties have agreed to the foregoing as of the date first set forth above.

3. Section 2.3(a) of the Agreement is hereby amended and restated to read in its entirety as follows:

(ii) Equipment Advances.

8. No course of dealing on the part of Bank or its officers, nor any failure or delay in the exercise of any right by Bank, shall operate as a waiver thereof, and any single or partial exercise of any such right shall not preclude any later exercise of any such right. Bank’s failure at any time to require strict performance by Borrower of any provision shall not affect any right of Bank thereafter to demand strict compliance and performance. Any suspension or waiver of a right must be in writing signed by an officer of Bank.

9. Unless otherwise defined, all initially capitalized terms in this Amendment shall be as defined in the Agreement. The Agreement, as amended hereby, shall be and remain in full force and effect in accordance with its respective terms and hereby is ratified and confirmed in all respects.

(p) “LIBOR Lending Office” means Bank’s office located in the Cayman Islands, British West Indies, or such other branch of Bank, domestic or foreign, as it may hereafter designate as its LIBOR Lending Office by notice to Borrower.

Subject to the terms and conditions of this Addendum, each of the Advances made under the Agreement shall bear interest at the LIBOR-based Rate or the Daily Adjusting LIBOR Rate, as elected by Borrower or as otherwise determined under this Addendum, except during any period of time during which, in accordance with the terms and conditions of this Addendum, the Indebtedness under the Agreement shall bear interest at the Prime-based Rate.

3. Payment of Interest on Advances. Accrued and unpaid interest on the unpaid balance of each outstanding Advance shall be payable monthly, in arrears, on the twentieth day of each month, until maturity (whether as stated herein, by acceleration, or otherwise). Subject to the definition of “LIBOR Period” hereunder, in the event that any payment under this Addendum becomes due and payable on any day which is not a Business Day, the due date thereof shall be extended to the next succeeding Business Day, and, to the extent applicable, interest shall continue to accrue and be payable thereon during such extension at the rates set forth in this Addendum.

4. Bank’s Records Re: Advances. The amount and date of each Advance, its Applicable Interest Rate, its LIBOR Period, if applicable, and the amount and date of any repayment shall be noted on Bank’s records, which records shall be conclusive evidence thereof, absent manifest error; provided, however, any failure by Bank to make any such notation, or any error in any such notation, shall not relieve Borrower of its obligations to repay Bank all amounts payable by Borrower to Bank under or pursuant to this Addendum and the Agreement, when due in accordance with the terms hereof. For any LIBOR-based Advance or any Daily Adjusting LIBOR Advance, if Bank shall designate a LIBOR Lending Office which maintains books separate from those of the rest of Bank, Bank shall have the option of maintaining and carrying such Advance on the books of such LIBOR Lending Office.

5. Selection/Conversion of Interest Rate Options. Borrower may request an Advance hereunder, including the refunding of an outstanding Advance as the same type of Advance or the conversion of an outstanding Advance to another type of Advance, upon the delivery to Bank of a Request for Advance executed by Borrower, subject to the following: (a) Bank shall not have made demand under the Agreement and no Event of Default, or any condition or event which, with the giving of notice or the running of time, or both, would constitute an Event of Default, shall have occurred and be continuing or exist under the Agreement; (b) each such Request for Advance shall set forth the information required on the Request for Advance form attached hereto as Exhibit “A”; (c) each such Request for Advance shall be delivered to Bank by 10:00 a.m. (California time) on the proposed date of the requested Advance; (d) the principal amount of each LIBOR-based Advance shall be at least Two Hundred Fifty Thousand Dollars ($250,000.00); (e) the proposed date of any refunding of any outstanding LIBOR-based Advance as another LIBOR-based Advance or the conversion of any outstanding LIBOR-based Advance to another type of Advance shall only be on the last day of the LIBOR Period applicable to such outstanding LIBOR-based Advance; and (f) a Request for Advance, once delivered to Bank, shall not be revocable by Borrower. There shall be no more than three (3) LIBOR Periods outstanding at any one time.

(h) Advances hereunder may be requested in Borrower’s discretion by telephonic notice to Bank. Any Advance requested by telephonic notice shall be confirmed by Borrower that same day by submission to Bank, either by first class mail, facsimile or other means of delivery acceptable to Bank, of the written Request for Advance aforementioned. Borrower acknowledges that if Bank makes an Advance based on a telephonic request, it shall be for Borrower’s convenience and all risks involved in the use of such procedure shall be borne by Borrower, and Borrower expressly agrees to indemnify and hold Bank harmless therefor. Bank shall have no duty to confirm the authority of anyone requesting an Advance by telephone.

(i) If, as to any outstanding LIBOR-based Advance, Bank shall not receive a timely Request for Advance, or telephonic notice, in accordance with the foregoing requesting the refunding or continuation of such Advance as another LIBOR-based Advance for a specified LIBOR Period or the conversion of such Advance to a Daily Adjusting LIBOR Rate Advance, effective as of the last day of the LIBOR Period applicable to such outstanding LIBOR-based Advance, and as of the last day of each succeeding LIBOR Period, the principal amount of such Advance which is not then repaid shall be automatically refunded or continued as a LIBOR-based Advance having a LIBOR Period equal to the same period of time as the LIBOR Period then ending for such outstanding LIBOR-based Advance, unless Borrower is/are not entitled to request LIBOR-based Advances hereunder or otherwise elect the LIBOR-based Rate as the Applicable Interest Rate for the principal Indebtedness outstanding hereunder in accordance with the terms of this Addendum, or the LIBOR-based Rate is not otherwise available to Borrower as the Applicable Interest Rate hereunder for the principal Indebtedness outstanding hereunder in accordance with the terms of this Addendum, in which case, the Prime-based Rate shall be the Applicable Interest Rate hereunder in respect of such Indebtedness for such period, subject in all respects to the terms and conditions of the Agreement. The foregoing shall not in any way whatsoever limit or otherwise affect Bank’s right to make demand for payment of all or any part of the Indebtedness at any time in Bank’s sole and absolute discretion or any of Bank’s rights or remedies under the Agreement upon the occurrence of any Event of Default thereunder, or any condition or event which, with the giving of notice or the running of time, or both, would constitute an Event of Default.

6. Default Interest Rate. From and after the occurrence of any Event of Default, and so long as any such Event of Default remains unremedied or uncured thereafter, the Indebtedness outstanding under the Agreement shall bear interest at a per annum rate of three percent (3%) above the otherwise Applicable Interest Rate, which interest shall be payable upon demand. In addition to the foregoing, a late payment charge equal to five percent (5%) of each late payment hereunder may be charged on any payment not received by Bank within ten (10) calendar

-6-

days after the payment due date therefor, but acceptance of payment of any such charge shall not constitute a waiver of any Event of Default under the Agreement. In no event shall the interest payable under this Addendum and the Agreement at any time exceed the maximum rate permitted by law.

7. Prepayment. If Borrower make(s) any payment of principal with respect to any LIBOR-based Advance on any day other than the last day of the LIBOR Period applicable thereto (whether voluntarily, by acceleration, required payment or otherwise), or if Borrower fail(s) to borrow any LIBOR-based Advance after notice has been given by Borrower (or any of them) to Bank in accordance with the terms of this Addendum requesting such Advance, or if Borrower fail(s) to make any payment of principal or interest in respect of a LIBOR-based Advance when due, Borrower shall reimburse Bank, on demand, for any resulting loss, cost or expense incurred by Bank as a result thereof, including, without limitation, any such loss, cost or expense incurred in obtaining, liquidating, employing or redeploying deposits from third parties, whether or not Bank shall have funded or committed to fund such Advance. Such amount payable by Borrower to Bank may include, without limitation, an amount equal to the excess, if any, of (a) the amount of interest which would have accrued on the amount so prepaid, or not so borrowed, refunded or converted, for the period from the date of such prepayment or of such failure to borrow, refund or convert, through the last day of the relevant LIBOR Period, at the applicable rate of interest for said Advance(s) provided under this Addendum, over (b) the amount of interest (as reasonably determined by Bank) which would have accrued to Bank on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank eurodollar market. Calculation of any amounts payable to Bank under this paragraph shall be made as though Bank shall have actually funded or committed to fund the relevant LIBOR-based Advance through the purchase of an underlying deposit in an amount equal to the amount of such Advance and having a maturity comparable to the relevant LIBOR Period; provided, however, that Bank may fund any LIBOR-based Advance in any manner it deems fit and the foregoing assumptions shall be utilized only for the purpose of the calculation of amounts payable under this paragraph. Upon the written request of Borrower, Bank shall deliver to Borrower a certificate setting forth the basis for determining such losses, costs and expenses, which certificate shall be conclusively presumed correct, absent manifest error. Borrower may prepay all or part of the outstanding balance of any Daily Adjusting LIBOR Rate Advance under this Addendum or any Indebtedness which is bearing interest at the Prime-based Rate at any such time without premium or penalty. Any prepayment hereunder shall also be accompanied by the payment of all accrued and unpaid interest on the amount so prepaid. Borrower hereby acknowledges and agrees that the foregoing shall not, in any way whatsoever, limit, restrict, or otherwise affect Bank’s right to make demand for payment of all or any part of the Indebtedness under the Agreement due on a demand basis in Bank’s sole and absolute discretion, whether such Indebtedness is bearing interest at the Daily Adjusting LIBOR Rate, the LIBOR-based Rate or the Prime-based Rate at such time.

BY INITIALING BELOW, BORROWER ACKNOWLEDGE(S) AND AGREE(S) THAT: (A) THERE IS NO RIGHT TO PREPAY ANY LIBOR-BASED RATE ADVANCE, IN WHOLE OR IN PART, WITHOUT PAYING THE PREPAYMENT AMOUNT SET FORTH HEREIN (“PREPAYMENT AMOUNT”), EXCEPT AS OTHERWISE REQUIRED UNDER APPLICABLE LAW; (B) BORROWER SHALL BE LIABLE FOR PAYMENT OF THE PREPAYMENT AMOUNT IF BANK EXERCISES ITS RIGHT TO ACCELERATE PAYMENT OF ANY LIBOR-BASED RATE ADVANCE AS PART OR ALL OF THE OBLIGATIONS OWING UNDER THE AGREEMENT, INCLUDING WITHOUT LIMITATION, ACCELERATION UNDER A DUE-ON-SALE PROVISION; (C) BORROWER WAIVES ANY RIGHTS UNDER SECTION 2954.10 OF THE CALIFORNIA CIVIL CODE OR ANY SUCCESSOR STATUTE; AND (D) BANK HAS MADE EACH LIBOR-BASED RATE ADVANCE PURSUANT TO THE AGREEMENT IN RELIANCE ON THESE AGREEMENTS.

BORROWER’S INITIALS

8. Regulatory Developments or Other Circumstances Relating to the LIBOR-based Rate or the Daily Adjusting LIBOR Rate.

(h) If, at any time, Bank determines that, (a) Bank is unable to determine or ascertain the LIBOR-based Rate or the Daily Adjusting LIBOR Rate, or (b) by reason of circumstances affecting the foreign exchange and interbank markets generally, deposits in eurodollars in the applicable amounts or for the relative maturities are not being offered to Bank for any applicable Advance or LIBOR Period, or (c) the LIBOR-based Rate or the Daily Adjusting LIBOR Rate will not accurately or fairly cover or reflect the cost to Bank of maintaining any

-7-

of the Indebtedness under this Addendum at the LIBOR-based Rate or the Daily Adjusting LIBOR Rate, then Bank shall forthwith give notice thereof to Borrower. Thereafter, until Bank notifies Borrower that such conditions or circumstances no longer exist, the right of Borrower to request a LIBOR-based Advance or a Daily Adjusting LIBOR Rate Advance and to convert an Advance to or refund an Advance as a LIBOR-based Advance or a Daily Adjusting LIBOR Rate Advance shall be suspended, and the Prime-based Rate shall be the Applicable Interest Rate for all Indebtedness during such period of time.

(i) If, after the date hereof, the introduction of, or any change in, any applicable law, rule or regulation or in the interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or compliance by Bank (or its LIBOR Lending Office) with any request or directive (whether or not having the force of law) of any such authority, shall make it unlawful or impossible for the Bank (or its LIBOR Lending Office) to make or maintain any Advance with interest at the LIBOR-based Rate or the Daily Adjusting LIBOR Rate, Bank shall forthwith give notice thereof to Borrower. Thereafter, (a) until Bank notifies Borrower that such conditions or circumstances no longer exist, the right of Borrower to request a LIBOR-based Advance or a Daily Adjusting LIBOR Rate Advance and to convert an Advance to or refund an Advance as a LIBOR-based Advance or a Daily Adjusting LIBOR Rate Advance shall be suspended, and thereafter, the Prime-based Rate shall be the Applicable Interest Rate for all Indebtedness, and (b) if Bank may not lawfully continue to maintain an outstanding LIBOR-based Advance to the end of the then current LIBOR Period applicable thereto, the Prime-based Rate shall be the Applicable Interest Rate for the remainder of such LIBOR Period with respect to such outstanding Advance.

(j) Further, at any time upon prior written notice to Borrower, Bank may, in its sole discretion based upon its good faith belief that the Prime-based Rate is an appropriate basis for its floating rate loans, suspend use of the Daily Adjusting LIBOR Rate as an Applicable Interest Rate hereunder, at which time, the Prime-based Rate shall thereafter replace the Daily Adjusting LIBOR Rate as an Applicable Interest Rate for Indebtedness outstanding under the Agreement, unless Bank, in its sole discretion based upon its good faith belief that the Prime-based Rate is no longer an appropriate basis for its floating rate loans, rescinds such notice, in which case, the Daily Adjusting LIBOR Rate shall, upon written notice from Bank to Borrower, again be an Applicable Interest Rate hereunder and use of the Prime-based Rate as an Applicable Interest Rate for Indebtedness outstanding under the Agreement shall be suspended.

(k) If the adoption after the date hereof, or any change after the date hereof in, any applicable law, rule or regulation (whether domestic or foreign) of any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by Bank (or its LIBOR Lending Office) with any request or directive (whether or not having the force of law) made by any such authority, central bank or comparable agency after the date hereof: (a) shall subject Bank (or its LIBOR Lending Office) to any tax, duty or other charge with respect to this Addendum or any Indebtedness under the Agreement, or shall change the basis of taxation of payments to Bank (or its LIBOR Lending Office) of the principal of or interest under this Addendum or any other amounts due under this Addendum in respect thereof (except for changes in the rate of tax on the overall net income of Bank or its LIBOR Lending Office imposed by the jurisdiction in which Bank’s principal executive office or LIBOR Lending Office is located); or (b) shall impose, modify or deem applicable any reserve (including, without limitation, any imposed by the Board of Governors of the Federal Reserve System), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by Bank (or its LIBOR Lending Office), or shall impose on Bank (or its LIBOR Lending Office) or the foreign exchange and interbank markets any other condition affecting this Addendum or the Indebtedness; and the result of any of the foregoing is to increase the cost to Bank of maintaining any part of the Indebtedness or to reduce the amount of any sum received or receivable by Bank under this Addendum by an amount deemed by the Bank to be material, then Borrower shall pay to Bank, within fifteen (15) days of Borrower’s receipt of written notice from Bank demanding such compensation, such additional amount or amounts as will compensate Bank for such increased cost or reduction. A certificate of Bank, prepared in good faith and in reasonable detail by Bank and submitted by Bank to Borrower, setting forth the basis for determining such additional amount or amounts necessary to compensate Bank shall be conclusive and binding for all purposes, absent manifest error.

(l) In the event that any applicable law, treaty, rule or regulation (whether domestic or foreign) now or hereafter in effect and whether or not presently applicable to Bank, or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof, or

-8-

compliance by Bank with any guideline, request or directive of any such authority (whether or not having the force of law), including any risk-based capital guidelines, affects or would affect the amount of capital required or expected to be maintained by Bank (or any corporation controlling Bank), and Bank determines that the amount of such capital is increased by or based upon the existence of any obligations of Bank hereunder or the maintaining of any Indebtedness, and such increase has the effect of reducing the rate of return on Bank’s (or such controlling corporation’s) capital as a consequence of such obligations or the maintaining of such Indebtedness to a level below that which Bank (or such controlling corporation) could have achieved but for such circumstances (taking into consideration its policies with respect to capital adequacy), then Borrower shall pay to Bank, within fifteen (15) days of Borrower’s receipt of written notice from Bank demanding such compensation, additional amounts as are sufficient to compensate Bank (or such controlling corporation) for any increase in the amount of capital and reduced rate of return which Bank reasonably determines to be allocable to the existence of any obligations of the Bank hereunder or to maintaining any Indebtedness. A certificate of Bank as to the amount of such compensation, prepared in good faith and in reasonable detail by the Bank and submitted by Bank to Borrower, shall be conclusive and binding for all purposes absent manifest error.

9. Legal Effect. Except as specifically modified hereby, all of the terms and conditions of the Agreement remain in full force and effect.

10. Conflicts. As to the matters specifically the subject of this Addendum, in the event of any conflict between this Addendum and the Agreement, the terms of this Addendum shall control.

11. Amendment and Restatement. This Addendum amends, restate, and replaces in its entirety that certain LIBOR Addendum to Loan and Security Agreement dated December 20, 2007 by and between Bank and Borrower.

IN WITNESS WHEREOF, the parties have agreed to the foregoing as of the date first set forth above.
