RECITALS

Silicon and Borrower have entered into that certain Loan and Security Agreement dated as of May 1, 2002, which Loan and Security Agreement was amended by that certain Loan Modification Agreement dated as of September 25, 2002 by and between Borrower and Silicon (collectively, the “Original Loan Agreement”). Pursuant to the Original Loan Agreement, Silicon agreed to make certain loans including, the “Revolving Facility” and the “Equipment Loan Sublimit” described therein, and other financial accommodations to Borrower. Borrower has requested and Silicon has agreed pursuant to this Agreement to (i) decrease the maximum principal amount of the Revolving Facility from Fifteen Million Dollars ($15,000,000) to Twelve Million Five Hundred Thousand Dollars ($12,500,000) (ii) terminate the existing Equipment Loan Sublimit, (iii) to make a new Equipment Loan to Borrower in the principal amount of Two Million Five Hundred Thousand Dollars ($2,500,000), and (iv) amend and restate the Original Loan Agreement.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Silicon and Borrower agree that the Original Loan Agreement is amended and restated in its entirety as follows:

1. LOANS.

     1.1 Loans. Silicon will make revolving loans to Borrower (the “Revolving Loan”), issue Letters of Credit, enter into FX Forward Contracts and provide Cash Management Services to Borrower (collectively the “Loans”), in amounts determined by Silicon in its good faith business judgment, up to the amounts (the “Credit Limit”) shown on the Schedule, provided no

-1-

Default or Event of Default has occurred and is continuing, and subject to deduction of Reserves for accrued interest and such other Reserves as Silicon deems proper from time to time in its good faith business judgment. The Borrower may from time to time, by giving Silicon prior written notice (a “Non-Borrowing Notice”), elect to cease requesting Loans under this Agreement and during such period, Silicon shall have no further obligation to make any such Loans (such periods each being called a “Non-Borrowing Period”). Each Non-Borrowing Notice shall be given to Silicon in accordance with Section 9.5 of this Agreement and shall set forth the date on which the Non-Borrowing Period shall commence, which date must be not earlier than one (1) Business Days after the date on which Silicon receives such notice and shall be signed by an officer of the Borrower. The Borrower may terminate a Non-Borrowing Period by giving Silicon not less than thirty (30) days prior written notice of its desire to terminate such Non-Borrowing Period, which notice once received, is not revocable.

     1.2 Interest. All Loans and all other monetary Obligations shall bear interest at the rate shown on the Schedule, except where expressly set forth to the contrary in this Agreement. Interest shall be payable monthly, on the last day of the month. Interest may, in Silicon’s discretion, be charged to Borrower’s loan account, and the same shall thereafter bear interest at the same rate as the other Loans. Silicon may, in its discretion, charge interest to Borrower’s Deposit Accounts maintained with Silicon. Silicon will provide Borrower with notice prior to any debit of Borrower’s loan account for any regularly scheduled payment.

     1.3 Overadvances. If at any time or for any reason the total of all outstanding Loans and all other monetary Obligations, including, without limitation, Exim Loans, Cash Management Services and the face amount of all outstanding Letters of Credit, exceeds the Credit Limit (an “Overadvance”), Borrower shall immediately pay the amount of the excess to Silicon, without notice or demand. Without limiting Borrower’s obligation to repay to Silicon the amount of any Overadvance, Borrower agrees to pay Silicon interest on the outstanding amount of any Overadvance, on demand, at the Default Rate.

     1.4 Fees. Borrower shall pay Silicon the fees shown on the Schedule, which are in addition to all interest and other sums payable to Silicon and are not refundable.

     1.5 Loan Requests. To obtain a Loan, Borrower shall make a request to Silicon by facsimile or telephone. Loan requests received after 12:00 Noon (Pacific standard time) will not be considered by Silicon until the next Business Day. Silicon may rely on any telephone request for a Loan given by a person whom Silicon believes is an authorized representative of Borrower, and Borrower will indemnify Silicon for any loss Silicon suffers as a result of that reliance.

     1.6 Letters of Credit Exposure.

          (a) At the request of Borrower, and as part of the Loans, Silicon may, in its good faith business judgment, issue or arrange for the issuance of letters of credit for the account of Borrower, in each case in form and substance satisfactory to Silicon in its sole discretion (collectively, “Letters of Credit”). The aggregate face amount of all Letters of Credit from time to time outstanding shall not exceed the amount shown on the Schedule (the “Letter of Credit Sublimit”), and shall be reserved against Loans which would otherwise be available hereunder, and in the event at any time there are insufficient Loans available to Borrower for such reserve, Borrower shall deposit and maintain with Silicon cash collateral in an amount at all times equal to such deficiency, which shall be held as Collateral for all purposes of this Agreement. Borrower shall pay all bank charges (including charges of Silicon) for the issuance of Letters of Credit, together with such additional fee as Silicon’s letter of credit department shall charge in connection with the issuance of the Letters of Credit. Any payment by Silicon under or in connection with a Letter of Credit shall constitute a Loan hereunder on the date such payment is made. Each Letter of Credit shall have an expiry date no later than thirty days prior to the Maturity Date. Borrower hereby agrees to indemnify and hold Silicon harmless from any loss, cost, expense, or liability, including payments made by Silicon, expenses, and reasonable attorneys’ fees incurred by Silicon arising out of or in connection with any Letters of Credit. Borrower agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guaranteed by Silicon and opened for Borrower’s account or by Silicon’s interpretations of any Letter of Credit issued by Silicon for Borrower’s account, and Borrower understands and agrees that Silicon shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrower’s instructions or those contained in the Letters of Credit or any modifications, amendments, or supplements thereto. Borrower understands that Letters of Credit may require Silicon to indemnify the issuing bank for certain costs or liabilities arising out of claims by Borrower against such issuing bank. Borrower hereby agrees to indemnify and hold Silicon harmless with respect to any loss, cost, expense, or liability incurred by Silicon under any Letter of Credit as a result of Silicon’s indemnification of any such issuing bank. The provisions of this Loan Agreement, as it pertains to Letters of Credit, and any other Loan Documents relating to Letters of Credit are cumulative.

The aggregate face amount of all FX Forward Contracts and FX Reserve from time to time outstanding shall not exceed the amount shown on the Schedule (the “Foreign Exchange Sublimit”), and shall be reserved against Loans which would otherwise be available hereunder, and in the event at any time there are insufficient Loans available to Borrower for such reserve, Borrower shall deposit and maintain with Silicon cash collateral in an amount at all times equal to such deficiency, which shall be held as Collateral for all purposes of this Agreement. Silicon will subtract ten percent (10%) of each outstanding FX Forward Contract (the “FX Reserve”) from the Foreign Exchange Sublimit. “). The total FX Forward Contracts at any one time may not exceed ten (10) times the amount of the FX Reserve. Silicon may terminate the FX Forward Contracts if a Default or an Event of Default occurs and is continuing.

     Borrower may use up to One Million Five Hundred Thousand Dollars ($1,500,000) of the Loans for Lender’s cash management services, which may include merchant services, direct deposit of payroll, business credit card, and check cashing services identified in various cash management services agreements related to such services (the “Cash Management Services”). Such aggregate amounts utilized under the Cash Management Services Sublimit will at all times reduce the amount otherwise available to be borrowed under the Loans. Any amounts Silicon pays on behalf of Borrower or any amounts that are not paid by Borrower for any Cash Management Services will be treated as Loans and will accrue interest at the Prime Rate in effect from time to time, plus one percent (1.00%) per annum.

     1.9 EximBank Loans. At the request of Borrower, as part of the Loans, Silicon may, subject to the satisfaction of certain conditions set forth herein, make certain Loans against Eligible Foreign Accounts (collectively, “Exim Loans” and each an “Exim Loan”). The aggregate face amount of all Exim Loans from time to time outstanding shall not exceed the amount shown on the Schedule (the “Exim Loan Sublimit”), and shall be reserved against Loans which would otherwise be available hereunder. Prior to making any Exim Loan, Silicon shall have received (a) a fully executed Borrower Agreement in form and substance satisfactory to Silicon, (b) a fully executed Loan Authorization Notice in form and substance satisfactory to Silicon, (c) payment of the Exim Bank Loan Fee, (d) a fully executed Exim Bank Loan and Security Agreement, and (e) such other documents as Silicon may deem necessary in connection with the Exim Loans (collectively, the “Exim Loan Documents”).

     1.10 Equipment Loans. In addition to the Loans, at the request of Borrower, Silicon will make equipment term loans to Borrower (the “Equipment Loans”), in amounts determined by Silicon in its good faith business judgment, up to the Equipment Loan Amount shown on the Schedule, provided no Default or Event of Default has occurred and is continuing.

-3-

representations will continue to be true, and that Borrower will at all times comply with all of the following covenants, throughout the term of this Agreement and until all Obligations have been paid and performed in full:

     3.1 Corporate Existence and Authority. Borrower is and will continue to be, duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation. Borrower is and will continue to be qualified and licensed to do business in all jurisdictions in which any failure to do so would result in a Material Adverse Change. The execution, delivery and performance by Borrower of this Agreement, and all other documents contemplated hereby (i) have been duly and validly authorized, (ii) are enforceable against Borrower in accordance with their terms (except as enforcement may be limited by equitable principles and by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to creditors’ rights generally), and (iii) do not violate Borrower’s articles or certificate of incorporation, or Borrower’s by-laws, or any law or any material agreement or instrument which is binding upon Borrower or its property, and (iv) do not constitute grounds for acceleration of any material indebtedness or obligation under any agreement or instrument which is binding upon Borrower or its property.

     3.2 Name; Trade Names and Styles. The name of Borrower set forth in the heading to this Agreement is its correct name. Listed in the Representations are all prior names of Borrower and all of Borrower’s present and prior trade names. Borrower shall give Silicon ten (10) days’ prior written notice before changing its name or doing business under any other name. Borrower has complied, and will in the future comply, in all material respects, with all laws relating to the conduct of business under a fictitious business name, except where the failure to so comply would not reasonably be expected to result in a Material Adverse Change.

     3.3 Place of Business; Location of Collateral. The address set forth in the heading to this Agreement is Borrower’s chief executive office. In addition, Borrower has places of business and Collateral is located only at the locations set forth in the Representations. Borrower will notify Silicon within thirty (30) days of opening any additional place of business, changing its chief executive office, or moving any of the Collateral to a location other than Borrower’s Address or one of the locations set forth in the Representations, except that Borrower may maintain sales offices in the ordinary course of business at which not more than a total of $10,000 fair market value of Equipment is located.

     3.4 Title to Collateral; Perfection; Permitted Liens.

          (a) Borrower is now, and will at all times in the future be, the sole owner of all the Collateral, except for items of Equipment which are leased to Borrower. The Collateral now is and will remain free and clear of any and all liens, charges, security interests, encumbrances and adverse claims, except for Permitted Liens. Silicon now has, and will continue to have, a first-priority perfected and enforceable security interest in all of the Collateral, subject only to the Permitted Liens, and Borrower will at all times defend Silicon and the Collateral against all claims of others.

          (b) Borrower has set forth in the Representations all of Borrower’s Deposit Accounts, and Borrower will give Silicon three (3) Business Days advance written notice before establishing any new Deposit Accounts and will cause the institution where any such new Deposit Account is maintained to execute and deliver to Silicon a control agreement in form sufficient to perfect Silicon’s security interest in the Deposit Account and otherwise satisfactory to Silicon in its good faith business judgment. Nothing herein limits any requirements which may be set forth in the Schedule as to where Deposit Accounts will be maintained.

          (c) In the event that Borrower shall at any time after the date hereof have any commercial tort claims against others, which it is asserting or intends to assert, and in which the potential recovery exceeds $500,000, Borrower shall promptly notify Silicon thereof in writing and provide Silicon with such information regarding the same as Silicon shall request (unless providing such information would waive the Borrower’s attorney-client privilege). Such notification to Silicon shall constitute a grant of a security interest in the commercial tort claim and all proceeds thereof to Silicon, and Borrower shall execute and deliver all such documents and take all such actions as Silicon shall request in connection therewith.

          (d) None of the Collateral now is or will be affixed to any real property in such a manner, or with such intent, as to become a fixture. Borrower is not and will not become a lessee under any real property lease pursuant to which the lessor may obtain any rights in any of the Collateral and no such lease now prohibits, restrains, impairs or will prohibit, restrain or impair Borrower’s right to remove any Collateral from the leased premises. Whenever any Collateral is located upon premises in which any third party has an interest, Borrower shall, whenever requested by Silicon, use its best efforts to cause such third party to execute and deliver to Silicon, in form acceptable to Silicon, such waivers and subordinations as Silicon

-4-

shall specify in its good faith business judgment. Borrower will keep in full force and effect, and will comply with all material terms of, any lease of real property where any of the Collateral now or in the future may be located.

     3.5 Maintenance of Collateral. Borrower will maintain the Collateral in good working condition (ordinary wear and tear excepted), and Borrower will not use the Collateral for any unlawful purpose. Borrower will promptly advise Silicon in writing of any material loss or damage to the Collateral.

     3.6 Books and Records. Borrower has maintained and will maintain at Borrower’s Address complete and accurate books and records, comprising an accounting system in accordance with GAAP.

     3.7 Financial Condition, Statements and Reports.

     3.8 Tax Returns and Payments; Pension Contributions.

Borrower may, however, defer payment of any contested taxes, provided that Borrower (i) in good faith contests Borrower’s obligation to pay the taxes by appropriate proceedings promptly and diligently instituted and conducted, (ii) notifies Silicon in writing of the commencement of, and any material development in, the proceedings, and (iii) posts bonds or takes any other steps required to keep the contested taxes from becoming a lien upon any of the Collateral. Borrower is unaware of any claims or adjustments proposed for any of Borrower’s prior tax years which could result in additional taxes becoming due and payable by Borrower. Borrower has paid, and shall continue to pay all amounts necessary to fund all present and future pension, profit sharing and deferred compensation plans in accordance with their terms, and Borrower has not and will not withdraw from participation in, permit partial or complete termination of, or permit the occurrence of any other event with respect to, any such plan which could reasonably be expected to result in any liability of Borrower, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency.

     3.9 Compliance with Law. Borrower has, to the best of its knowledge, complied, and will comply, in all material respects, with all provisions of all foreign, federal, state and local laws and regulations applicable to Borrower, including, but not limited to, those relating to Borrower’s ownership of real or personal property, the conduct and licensing of Borrower’s business, and all environmental matters.

     3.10 Litigation. Except as set forth in the Schedule, there is no claim, suit, litigation, proceeding or investigation pending or (to best of Borrower’s knowledge) threatened against or affecting Borrower in any court or before any governmental agency (or any basis therefor known to Borrower) which could reasonably be expected to result, either separately or in the aggregate, in any Material Adverse Change. Borrower will promptly inform Silicon in writing of any claim, proceeding, litigation or investigation in the future threatened or instituted against Borrower involving any single claim of $50,000 or more, or involving $100,000 or more in the aggregate.

     3.11 Use of Proceeds. All proceeds of all Loans shall be used solely for lawful business purposes. Borrower is not purchasing or carrying any “margin stock” (as defined in Regulation U of the Board of Governors of the Federal Reserve System) and no part of the proceeds of any Loan will be used to purchase or carry any “margin stock” or to extend credit to others for the purpose of purchasing or carrying any “margin stock.”

     3.12 Operating Subsidiaries. All of Borrower’s operating Subsidiaries are parties to this Agreement.

4. Accounts.

     4.1 Representations Relating to Accounts. Borrower represents and warrants to Silicon as follows: Each Account with respect to which Loans are requested by Borrower shall, on the date each Loan is requested and made, (i) represent an undisputed bona fide existing unconditional obligation of the Account Debtor created by the sale, delivery, and acceptance of goods or the rendition of services, or the non-exclusive licensing of Intellectual Property, in the ordinary course of Borrower’s business, and (ii) meet the Minimum Eligibility Requirements set forth in Section 8 below.

     4.2 Representations Relating to Documents and Legal Compliance. Borrower represents and warrants to Silicon as follows: All statements made and all unpaid balances appearing in all invoices, instruments and other documents evidencing the Accounts are and shall be true and correct and all such invoices, instruments and other documents and all of Borrower’s

-5-

books and records are and shall be genuine and in all respects what they purport to be.

To the best of Borrower’s knowledge, all signatures and endorsements on all documents, instruments, and agreements relating to all Accounts are and shall be genuine, and all such documents, instruments and agreements are and shall be legally enforceable in accordance with their terms.

     4.3 Schedules and Documents Relating to Accounts. Borrower shall deliver to Silicon transaction reports and schedules of collections, as provided in the Schedule, on Silicon’s standard forms; provided, however, that Borrower’s failure to execute and deliver the same shall not affect or limit Silicon’s security interest and other rights in all of Borrower’s Accounts, nor shall Silicon’s failure to advance or lend against a specific Account affect or limit Silicon’s security interest and other rights therein. If requested by Silicon in its reasonable judgment, Borrower shall furnish Silicon with copies (or, at Silicon’s request, originals) of all contracts, orders, invoices, and other similar documents, and all shipping instructions, delivery receipts, bills of lading, and other evidence of delivery, for any goods the sale or disposition of which gave rise to such Accounts, and Borrower warrants the genuineness of all of the foregoing. Borrower shall also furnish to Silicon an aged accounts receivable trial balance as provided in the Schedule.

     4.4 Collection of Accounts. Borrower shall have the right to collect all Accounts, unless and until a Default or an Event of Default has occurred and is continuing. Whether or not an Event of Default has occurred and is continuing, Borrower shall hold all payments on, and proceeds of, Accounts in trust for Silicon, and Borrower shall immediately deliver all such payments and proceeds to Silicon in their original form, duly endorsed, to be applied to the Obligations in such order as Silicon shall determine. Silicon may, in its good faith business judgment, require that all proceeds of Collateral be deposited by Borrower into a lockbox account, or such other “blocked account” as Silicon may specify, pursuant to a blocked account agreement in such form as Silicon may specify in its good faith business judgment.

     4.5. Remittance of Proceeds. All proceeds arising from the disposition of any Collateral shall be delivered, in kind, by Borrower to Silicon in the original form in which received by Borrower not later than the following Business Day after receipt by Borrower, to be applied to the Obligations in such order as Silicon shall determine; provided that, if no Default or Event of Default has occurred and is continuing, Borrower shall not be obligated to remit to Silicon the proceeds of the sale of worn out or obsolete Equipment disposed of by Borrower in good faith in an arm’s length transaction for a purchase price of $25,000 or less (for all such transactions in any fiscal year). Borrower agrees that it will not commingle proceeds of Collateral with any of Borrower’s other funds or property, but will hold such proceeds separate and apart from such other funds and property and in an express trust for Silicon. Nothing in this Section limits the restrictions on disposition of Collateral set forth elsewhere in this Agreement.

     4.6 Disputes. Borrower shall notify Silicon promptly of all disputes or claims relating to Accounts. Borrower shall not forgive (completely or partially), compromise or settle any Account for less than payment in full, or agree to do any of the foregoing, except that Borrower may do so, provided that: (i) Borrower does so in good faith, in a commercially reasonable manner, in the ordinary course of business, and in arm’s length transactions, which are reported to Silicon on the regular reports provided to Silicon; (ii) no Default or Event of Default has occurred and is continuing; and (iii) taking into account all such discounts, settlements and forgiveness, the total outstanding Loans will not exceed the Credit Limit.

     4.7 Returns. Provided no Event of Default has occurred and is continuing, if any Account Debtor returns any Inventory to Borrower, Borrower shall promptly determine the reason for such return and promptly issue a credit memorandum to the Account Debtor in the appropriate amount. In the event any attempted return occurs after the occurrence and during the continuance of any Event of Default, Borrower shall hold the returned Inventory in trust for Silicon, and immediately notify Silicon of the return of the Inventory.

     4.8 Verification. Silicon may, from time to time, verify directly with the respective Account Debtors the validity, amount and other matters relating to the Accounts, by means of mail, telephone or otherwise, either in the name of Borrower or Silicon or such other name as Silicon may choose. Silicon will provide Borrower with notice of any such action.

     4.9 No Liability. Silicon shall not be responsible or liable for any shortage or discrepancy in, damage to, or loss or destruction of, any goods, the sale or other disposition of which gives rise to an Account, or for any error, act, omission, or delay of any kind occurring in the settlement, failure to settle, collection or failure to collect any Account, or for settling any Account in good faith for less than the full amount thereof, nor shall Silicon be deemed to be responsible for any of

-6-

Borrower’s obligations under any contract or agreement giving rise to an Account. Nothing herein shall, however, relieve Silicon from liability for its own gross negligence or willful misconduct.

     4.10 Exim Insurance. If required by Silicon, at all times that any Exim Loans are outstanding, Borrower will obtain, and pay when due all premiums with respect to, and maintain uninterrupted foreign credit insurance. In addition, Borrower will execute in favor of Silicon an assignment of proceeds of any insurance policy obtained by Borrower and issued by Exim Bank insuring against comprehensive commercial and political risk (the “EXIM Bank Policy”). The insurance proceeds from the EXIM Bank Policy assigned or paid to Silicon will be applied to the balance outstanding of Exim Loans made under this Agreement. Borrower will immediately notify Bank and Exim Bank in writing upon submission of any claim under the Exim Bank Policy. Then Silicon will not be obligated to make any further Loans to Borrower without prior approval from Exim Bank.

     5.2 Insurance. Borrower shall, at all times insure all of the tangible personal property Collateral and carry such other business insurance, with insurers reasonably acceptable to Silicon, in such form and amounts as Silicon may reasonably require and that are customary and in accordance with standard practices for Borrower’s industry and locations, and Borrower shall provide evidence of such insurance to Silicon. All such insurance policies shall name Silicon as an additional loss payee, and shall contain a lenders loss payee endorsement in form reasonably acceptable to Silicon. Upon receipt of the proceeds of any such insurance, Silicon shall apply such proceeds in reduction of the Obligations as Silicon shall determine in its good faith business judgment, except that, provided no Default or Event of Default has occurred and is continuing, Silicon shall release to Borrower insurance proceeds with respect to Equipment totaling less than $100,000, which shall be utilized by Borrower for the replacement of the Equipment with respect to which the insurance proceeds were paid. Silicon may require reasonable assurance that the insurance proceeds so released will be so used.

Any surplus shall be paid to Borrower or other persons legally entitled thereto; Borrower shall remain liable to Silicon for any deficiency. If, Silicon, in its good faith business judgment, directly or indirectly enters into a deferred payment or other credit transaction with any purchaser at any sale of Collateral, Silicon shall have the option, exercisable at any time, in its good faith business judgment, of either reducing the Obligations by the principal amount of purchase price or deferring the reduction of the Obligations until the actual receipt by Silicon of the cash therefor.

     7.6 Remedies Cumulative.

9. GENERAL PROVISIONS.

     9.1 Interest Computation. In computing interest on the Obligations, all wire transfers shall be deemed applied on account of the Obligations on the day of receipt by Silicon thereof and all checks and other items of payment received by Silicon (including proceeds of Accounts and payment of the Obligations in full) shall be deemed applied by Silicon on account of the Obligations two (2) Business Days after receipt by Silicon. For purposes of the foregoing, any such funds received after 12:00 Noon (Pacific standard time) on any day shall be deemed received on the next Business Day. Silicon shall not, however, be required to credit Borrower’s account for the amount of any item of payment which is unsatisfactory to Silicon in its good faith business judgment, and Silicon may charge Borrower’s loan account for the amount of any item of payment which is returned to Silicon unpaid.

     9.2 Application of Payments. All payments with respect to the Obligations may be applied, and in Silicon’s good faith business judgment reversed and re-applied, to the Obligations, in such order and manner as Silicon shall determine in its good faith business judgment.

     9.3 Charges to Accounts. Silicon may, in its discretion, require that Borrower pay monetary Obligations in cash to Silicon, or charge them to Borrower’s Loan account with notice, prior to the occurrence and continuance of an Event of Default, but without notice thereafter, in which event they will bear interest at the same rate applicable to the Loans. Silicon may also, in its discretion, charge any monetary Obligations to Borrower’s Deposit Accounts maintained with Silicon.

     9.4 Monthly Accountings. Silicon shall provide Borrower monthly with an account of advances, charges, expenses and payments made pursuant to this Agreement. Such account shall be deemed correct, accurate and binding on Borrower and an account stated (except for reverses and reapplications of payments made and corrections of errors discovered by Silicon), unless Borrower notifies Silicon in writing to the contrary within 60 days after such account is rendered, describing the nature of any alleged errors or omissions.

     9.5 Notices. All notices to be given under this Agreement shall be in writing and shall be given either personally or by reputable private delivery service or by fax or email or by regular first-class mail, or certified mail return receipt requested, addressed to Silicon or Borrower at each of the addresses shown in the heading to this Agreement, or at any other address designated in writing by one party to the other party. Any notices given by fax or email must be followed by notice by another of the means set forth above to be effective. Notices to Silicon shall be directed to the Commercial Finance Division, to the attention of the Division Manager or the Division Credit Manager. All notices shall be deemed to have been given upon delivery in the case of notices personally delivered, or at the expiration of one Business Day following delivery to the private delivery service, or two Business Days following the deposit thereof in the United States mail, with postage prepaid.

     9.6 Severability. Should any provision of this Agreement be held by any court of competent jurisdiction to be void or unenforceable, such defect shall not affect the remainder of this Agreement, which shall continue in full force and effect.

     9.7 Integration. This Agreement and such other written agreements, documents and instruments as may be executed in connection herewith are the final, entire and complete agreement between Borrower and Silicon and supersede all prior and contemporaneous negotiations and oral representations and agreements, all of which are merged and integrated in this Agreement. There are no oral understandings, representations or agreements between the parties which are not set forth in this Agreement or in other written agreements signed by the parties in connection herewith.

     9.8 Waivers; Indemnity. The failure of Silicon at any time or times to require Borrower to strictly comply with any of the provisions of this Agreement or any other Loan Document shall not waive or diminish any right of Silicon later to demand and receive strict compliance therewith. Any waiver of any default shall not waive or affect any other default, whether prior or subsequent, and whether or not similar. None of the provisions of this Agreement or any other Loan Document shall be deemed to have been waived by any act or knowledge of Silicon or its agents or employees, but only by a specific written waiver signed by an authorized officer of Silicon and delivered to Borrower. Borrower waives the benefit of all statutes of limitations relating to any of the Obligations or this Agreement or any other Loan Document, and Borrower waives demand, protest, notice of protest and notice of default or dishonor, notice of payment and nonpayment, release, compromise, settlement, extension or renewal of any commercial paper, instrument, account, General Intangible, document or guaranty at any time held by Silicon on which Borrower is or may in any way be liable, and notice of any action taken by Silicon, unless expressly required by this Agreement. Borrower hereby agrees to indemnify Silicon and its affiliates, subsidiaries, parent, directors, officers, employees, agents, and attorneys, and to hold them harmless from and against any and all claims, debts, liabilities, demands, obligations, actions, causes of action, penalties, costs and expenses (including reasonable attorneys’

-15-

fees), of every kind, which they may sustain or incur based upon or arising out of any of the Obligations, or any relationship or agreement between Silicon and Borrower, or any other matter, relating to Borrower or the Obligations; provided that this indemnity shall not extend to damages proximately caused by the indemnitee’s own gross negligence or willful misconduct and further provided that in any action or proceeding between Borrower and Silicon arising out of this Agreement or any Loan Documents, the prevailing party will be entitled to recover its reasonable attorneys’ fees and other reasonable costs and expenses incurred, in addition to any other relief to which it may be entitled. Notwithstanding any provision in this Agreement to the contrary, the indemnity agreement set forth in this Section shall survive any termination of this Agreement and shall for all purposes continue in full force and effect.

     9.9 No Liability for Ordinary Negligence. Neither Silicon, nor any of its directors, officers, employees, agents, attorneys or any other Person affiliated with or representing Silicon shall be liable for any claims, demands, losses or damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower or any other party through the ordinary negligence of Silicon, or any of its directors, officers, employees, agents, attorneys or any other Person affiliated with or representing Silicon, but nothing herein shall relieve Silicon from liability for its own gross negligence or willful misconduct.

     9.10 Amendment. The terms and provisions of this Agreement may not be waived or amended, except in a writing executed by Borrower and a duly authorized officer of Silicon.

     9.11 Time of Essence. Time is of the essence in the performance by Borrower of each and every obligation under this Agreement.

     9.12 Attorneys Fees and Costs. Borrower shall reimburse Silicon for all reasonable attorneys’ fees and all filing, recording, search, title insurance, appraisal, audit, and other reasonable costs incurred by Silicon, pursuant to, or in connection with, or relating to this Agreement (whether or not a lawsuit is filed), including, but not limited to, any reasonable attorneys’ fees and costs Silicon incurs in order to do the following: prepare and negotiate this Agreement and all present and future documents relating to this Agreement; obtain legal advice in connection with this Agreement or Borrower; enforce, or seek to enforce, any of its rights; prosecute actions against, or defend actions by, Account Debtors; commence, intervene in, or defend any action or proceeding; initiate any complaint to be relieved of the automatic stay in bankruptcy; file or prosecute any probate claim, bankruptcy claim, third-party claim, or other claim; examine, audit, copy, and inspect any of the Collateral or any of Borrower’s books and records; protect, obtain possession of, lease, dispose of, or otherwise enforce Silicon’s security interest in, the Collateral; and otherwise represent Silicon in any litigation relating to Borrower. In satisfying Borrower’s obligation hereunder to reimburse Silicon for attorneys fees, Borrower may, for convenience, issue checks directly to Silicon’s attorneys, Troutman Sanders LLP, but Borrower acknowledges and agrees that Troutman Sanders LLP is representing only Silicon and not Borrower in connection with this Agreement. If either Silicon or Borrower files any lawsuit against the other predicated on a breach of this Agreement, the prevailing party in such action shall be entitled to recover its reasonable costs and attorneys’ fees, including (but not limited to) reasonable attorneys’ fees and costs incurred in the enforcement of, execution upon or defense of any order, decree, award or judgment. All attorneys’ fees and costs to which Silicon may be entitled pursuant to this Paragraph shall immediately become part of Borrower’s Obligations, shall be due on demand, and shall bear interest at a rate equal to the highest interest rate applicable to any of the Obligations.

     9.13 Benefit of Agreement. The provisions of this Agreement shall be binding upon and inure to the benefit of the respective successors, assigns, heirs, beneficiaries and representatives of Borrower and Silicon; provided, however, that Borrower may not assign or transfer any of its rights under this Agreement without the prior written consent of Silicon, and any prohibited assignment shall be void. No consent by Silicon to any assignment shall release Borrower from its liability for the Obligations.

     9.14 Joint and Several Liability. If Borrower consists of more than one Person, their liability shall be joint and several, and the compromise of any claim with, or the release of, any Borrower shall not constitute a compromise with, or a release of, any other Borrower.

     9.15 Limitation of Actions. Any claim or cause of action by Borrower against Silicon, its directors, officers, employees, agents, accountants or attorneys, based upon, arising from, or relating to this Loan Agreement, or any other Loan Document, or any other transaction contemplated hereby or thereby or relating hereto or thereto, or any other matter, cause or thing whatsoever, occurred, done, omitted or suffered to be done by Silicon, its directors, officers, employees, agents, accountants or attorneys, shall be barred unless asserted by Borrower by the commencement of an action or proceeding in a court of competent jurisdiction by the filing of a complaint within one year after the first act, occurrence or omission upon which such claim or cause of action, or any part thereof, is based, and the service of a summons and complaint on an officer of Silicon, or

-16-

on any other person authorized to accept service on behalf of Silicon, within thirty (30) days thereafter. Borrower agrees that such one-year period is a reasonable and sufficient time for Borrower to investigate and act upon any such claim or cause of action. The one-year period provided herein shall not be waived, tolled, or extended except by the written consent of Silicon in its sole discretion. This provision shall survive any termination of this Loan Agreement or any other Loan Document.

     9.16 Paragraph Headings; Construction. Paragraph headings are only used in this Agreement for convenience. Borrower and Silicon acknowledge that the headings may not describe completely the subject matter of the applicable paragraph, and the headings shall not be used in any manner to construe, limit, define or interpret any term or provision of this Agreement. This Agreement has been fully reviewed and negotiated between the parties and no uncertainty or ambiguity in any term or provision of this Agreement shall be construed strictly against Silicon or Borrower under any rule of construction or otherwise.

     9.17 Governing Law; Jurisdiction; Venue. This Agreement and all acts and transactions hereunder and all rights and obligations of Silicon and Borrower shall be governed by the laws of the State of Maryland. As a material part of the consideration to Silicon to enter into this Agreement, Borrower (i) agrees that all actions and proceedings relating directly or indirectly to this Agreement shall, at Silicon’s option, be litigated in courts located within Maryland, and that the exclusive venue therefor shall be Santa Clara County; (ii) consents to the jurisdiction and venue of any such court and consents to service of process in any such action or proceeding by personal delivery or any other method permitted by law; and (iii) waives any and all rights Borrower may have to object to the jurisdiction of any such court, or to transfer or change the venue of any such action or proceeding.

     9.18 Mutual Waiver of Jury Trial. Borrower and Silicon each hereby waives the right to trial by jury in any action or proceeding based upon, arising out of, or in any way relating to, this Agreement or any other present or future instrument or agreement between Silicon and Borrower, or any conduct, acts or omissions of Silicon or Borrower or any of their directors, officers, employees, agents, attorneys or any other persons affiliated with Silicon or Borrower, in all of the foregoing cases, whether sounding in contract or tort or otherwise.

     9.19 Exim Notification. Silicon has the right to immediately notify Exim Bank in writing if it has knowledge of any of the following events: (1) any failure to pay any amount due under this Agreement; (2) the Exim Borrowing Base is less than the sum of the outstanding Exim Loans; (3) any failure to pay when due any amount payable to Silicon under any Loan owing by Borrower to Silicon; (4) the filing of an action for debtor’s relief by, against or on behalf of Borrower; (5) any threatened or pending material litigation against Borrower, or any dispute involving Borrower. If Silicon sends a notice to Exim Bank, Silicon has the right to send Exim Bank a written report on the status of events covered by the notice every thirty (30) days after the date of the original notification, until Silicon files a claim with Exim Bank or the defaults have been cured (but no Loans may be required during the cure period unless Exim Bank gives its written approval). If directed by Exim Bank, Silicon will have the right to exercise any rights it may have against Borrower to demand the immediate repayment of all amount outstanding under the Loans.
