THIS LOAN AND SECURITY AGREEMENT (as amended, modified, or otherwise supplemented from time to time, this “Agreement”) is entered into on the above date between SILICON VALLEY BANK, a California-chartered bank, with its principal place of business at ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ and with a loan production office located at ▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (“Silicon”) and the borrower named above (the “Borrower”), whose chief executive office is located at the above address (“Borrower’s Address”). The Schedule and Exhibits to this Agreement (the “Schedule” and the “Exhibits,” respectively) shall for all purposes be deemed to be part of this Agreement, and the same are integral parts of this Agreement. (Definitions of certain terms used in this Agreement are set forth in Section 8 below.)

Section 1 LOANS.

1.1 Loans. Silicon will, in its good faith business judgment, make revolving loans to Borrower (the “Loans’) up to the amounts (the “Credit Limit”) shown on the Schedule, provided no Default or Event of Default has occurred and is continuing, and subject to deduction of any Reserves for accrued interest and such other Reserves as Silicon deems proper from time to time in its good faith business judgment. Amounts borrowed may be repaid and reborrowed during the term of this Agreement.

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 shall be charged to a deposit account with Silicon designated by Borrower, or if no funds are available in any such deposit account, then as a Loan under this Agreement.

1.3 Overadvances. If at any time or for any reason the total of all outstanding Loans and all other monetary Obligations (including extensions of credit under Section 1.6, Section 1.7, and Section 1.8) 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 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 reasonably 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. At the request of Borrower, 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 outstanding from time to time (plus all Silicon exposure under any foreign exchange contracts and Cash Management Services entered into with Borrower or provided on behalf of Borrower under this Agreement) 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 in accordance with the terms of Section 1 of the Schedule, and in the event at any time the aggregate amount of Loans, Letters of Credit and any other financial accommodations hereunder exceed the Credit Limit, Borrower shall deposit and maintain with Silicon cash collateral in an amount at all times equal to such excess, which shall be held as Collateral for all purposes of this Agreement. Borrower shall pay all reasonable 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 (to the extent that such payment amount exceeds any cash collateral provided for such Letter of Credit) 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 unless such Letter of Credit is fully secured by cash collateral to the extent and in the amount described in Section 6.2 hereof. Borrower hereby agrees to indemnify, save, 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 unless such loss, cost, expense, or liability is caused by Silicon’s gross negligence or willful misconduct. 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 except to the extent that such liabilities are caused by the gross negligence or willful misconduct of Silicon. 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 unless such loss, cost, expense, or liability is caused by Silicon’s gross negligence or willful misconduct. The provisions of this Agreement, as it pertains to Letters of Credit, and any other Loan Documents relating to Letters of Credit are cumulative.

1.7 Foreign Exchange Sublimit. In addition to Section 1.5, Section 1.6 and Section 1.8, Borrower may use up to the amount set forth on the Schedule in connection with foreign exchange forward contracts with Silicon under which Borrower commits to purchase from or sell to Silicon a set amount of foreign currency more than one business day after the contract date. Silicon shall subtract up to a maximum of 10% of the amount of each outstanding foreign exchange contract from the foreign exchange sublimit (the “FX Reserve”). Silicon may terminate the foreign exchange contracts if an Event of Default occurs and continues.

1.8 Cash Management Services Sublimit. In addition to Section 1.5, 1.6 and 1.7 above, Borrower may also use up to the amount set forth on the Schedule for Cash Management Services. Such aggregate amounts utilized under the Cash Management Services Sublimit shall at all times reduce the amount otherwise available for Loans, letters of credit, foreign exchange contracts or other credit accommodations hereunder. 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 hereunder and will accrue interest at the interest rate applicable to Loans.

Section 2 SECURITY INTEREST.

2.1 Security Interest. To secure the payment and performance of all of the Obligations when due, and the performance of each of the Borrower’s duties under this Agreement and all documents executed in connection herewith, Borrower hereby grants to Silicon a continuing security interest in all of Borrower’s interest in the following, whether now owned or hereafter acquired, and wherever located: All Inventory, Equipment, Payment Intangibles, Letter-of-Credit Rights, Supporting Obligations, Accounts, and General Intangibles, including, without limitation, all of Borrower’s Intellectual Property, Deposit Accounts, and all money, and all property now or at any time in the future in Silicon’s possession (including claims and credit balances), and all proceeds (including proceeds of any insurance policies, proceeds of proceeds and claims against third parties), all products and all books and records related to any of the foregoing (all of the foregoing, together with all other property in which Silicon may now or in the future be granted a lien or security interest by Borrower, is referred to herein, collectively, as the “Collateral”). The security interest granted herein shall be a first priority security interest in the Collateral, subject to Permitted Liens. Except as disclosed to Silicon in writing, Borrower is not a party to, nor is bound by, any material license or other material agreement with respect to which the Borrower is the licensee that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement or any other property. Borrower will provide written notice to Silicon within thirty (30) days of entering or becoming bound by any such material license or material agreement which is reasonably likely to have a material impact on Borrower’s business or financial condition (other than over-the-counter software that is commercially available to the public). Borrower shall take such steps as Silicon reasonably requests to obtain the consent of, or waiver by, any person whose consent or waiver is necessary for all such licenses or contract rights to be deemed “Collateral” and for Silicon to have a security interest in it that might otherwise be restricted or prohibited by law or by the terms of any such license or agreement, whether now existing or entered into in the future. Notwithstanding the foregoing, the security interest granted herein does not extend to, and the term “Collateral” does not include (i) any outstanding capital stock of a controlled foreign corporation (as defined in the Internal Revenue Code of 1986, as amended) in excess of 65% of the voting power of all classes of capital stock of such controlled foreign corporation entitled to vote, or (ii) Equipment (and additions, accessions, parts, replacements, fixtures, improvements and accessions to, and proceeds of, such Equipment) secured by Permitted Liens described in clause (i) of the definition of Permitted Liens but only to the extent that Borrower is prohibited by any existing agreement related to such purchase money debt from granting other liens, security interests or encumbrances on such Equipment) and additions, accessions, parts, replacements, fixtures, improvements and accessions to, and proceeds of, such Equipment) so long as such prohibition remains in effect.

Section 3 REPRESENTATIONS, WARRANTIES AND COVENANTS OF BORROWER.

In order to induce Silicon to enter into this Agreement and to make Loans and except as disclosed on the Representations and Warranties Certificate, Borrower represents and warrants to Silicon as follows, and Borrower covenants that the following representations are true as of the date hereof, and as of the date of any request for a Loan or other financial accommodation hereunder, 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 organization. Borrower is and will continue to

be qualified and licensed to do business in all jurisdictions in which any failure to do so would have a material adverse effect on Borrower. The execution, delivery and performance by Borrower of this Agreement, and all other documents contemplated hereby (i) have been duly and validly authorized by Borrower, (ii) are enforceable against Borrower in accordance with their terms (except as enforcement may be limited by equitable principles (whether considered in a proceeding in equity or at law) and by bankruptcy, insolvency, reorganization, moratorium or similar laws relating to creditors’ rights generally), (iii) do not violate Borrower’s organizational documents, or any law or any material agreement or instrument which is binding upon Borrower or its property, except where such violation would not reasonably be expected to have a materially adverse effect on the business or financial condition of Borrower, and (iv) do not constitute grounds for acceleration of any material indebtedness or obligation under any material 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 name as set forth in its certificate of incorporation, as amended, on the date hereof. Listed on the Representations and Warranties Certificate are all prior names of Borrower and all of Borrower’s present and prior trade names. Borrower shall give Silicon 10 days’ prior written notice before changing its name or doing business under any other name.

3.3 Place of Business; Location of Collateral. The address set forth in the heading to this Agreement is Borrower’s chief executive office as of the date of this Agreement. In addition, as of the date hereof Borrower has places of business and Collateral is located only at the locations set forth on the Representations and Warranties Certificate. Borrower will give Silicon at least 30 days prior written notice before opening any additional place of business, changing its state of formation or moving any of the Collateral to a location other than Borrower’s Address or one of the locations set forth on the Representations and Warranties Certificate, except that Borrower may maintain sales offices in the ordinary course of business at which not more than a total of $75,000 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. To the best of Borrower’s knowledge, Silicon now has, and will continue to have, until Obligations under this Agreement are paid in full and this Agreement is terminated, 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 (other than with respect to Permitted Liens) until Obligations under this Agreement are paid in full and this Agreement is terminated.

(b) Borrower has set forth in the Representations and Warranties Certificate all of Borrower’s Deposit Accounts as of the date of this Agreement, and Borrower will give Silicon five 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 reasonably 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 could reasonably be expected to exceed $100,000, Borrower shall promptly notify Silicon thereof in writing and provide Silicon with such information regarding the same as Silicon shall reasonably 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 other than any landlord’s lien available to a lessor by statute or common law (provided, however, such lien shall be at all times junior and subordinate to the lien of Silicon) 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 reasonable efforts to cause such third party to execute and deliver to Silicon, in form reasonably acceptable to Silicon, such waivers and subordinations as Silicon 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 material lease of real property where any of the Collateral now or in the future may be located, except to the extent that the failure to so comply could not reasonably be expected to result in a material adverse effect on Borrower.

(e) Borrower hereby authorizes Silicon to file financing statements, without notice to Borrower, with all appropriate jurisdictions in order to perfect or protect Silicon’s interest or rights hereunder, which financing statements may indicate the Collateral as “all assets of the Debtor” or words of similar effect, or as being of an equal or lesser scope, or with greater detail, all in Silicon’s discretion.

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, from which financial statements prepared in accordance with GAAP may be prepared.

3.7 Financial Condition, Statements and Reports. All financial statements now or in the future delivered to Silicon have been, and will be, prepared in conformity with GAAP and now and in the future will (subject to appropriate adjustments and absence of footnotes in the case of interim period financial statements) and fairly present in all material respects the results of operations and financial condition of Borrower, in accordance with GAAP, at the times and for the periods therein stated. Between the last date covered by any such statement provided to Silicon and the date hereof, there has been no material adverse change in the financial condition or business of Borrower. Borrower is not currently, and will not be at any time during the term of this Agreement, insolvent (as defined in the Code).

3.8 Tax Returns and Payments; Pension Contributions. Borrower has timely filed, and will timely file, all required tax returns and reports, and Borrower has timely paid, and will timely pay, all foreign, federal, state

and local taxes, assessments, deposits and contributions now or in the future owed by Borrower. 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 a material liability of Borrower, including any material 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 to the extent such failure to comply with such law or regulation would reasonably be expected to have materially adverse effect on Borrower.

3.10 Litigation. Except as disclosed in the Representations and Warranties Certificate, there is no claim, suit, litigation, proceeding or investigation pending or (to Borrower’s knowledge) threatened in writing by or against Borrower in any court or before any governmental agency which could reasonably be expected to result, either separately or in the aggregate, in any material adverse change in the financial condition or business of Borrower, or in any material impairment in the ability of Borrower to carry on its business in substantially the same manner as it is now being conducted. Borrower will promptly inform Silicon in writing of any claim, proceeding, litigation or investigation in the future threatened in writing or instituted by or against Borrower involving any single claim of $100,000 or more, or involving $250,000 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.”

Section 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 in all material respects as of the date of such invoice, instrument, or document and all such invoices, instruments and other documents and all of Borrower’s books and records are and shall be genuine and in all respects what they purport to be. All sales and

other transactions underlying or giving rise to each Account shall fully comply in all material respects with all applicable laws and governmental rules and regulations to the extent that such failure to comply would reasonably be expected to have a material adverse effect on Borrower. To 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 except as may be limited by equitable principles (whether considered in a proceeding at law or in equity), and by bankruptcy, insolvency, reorganization, moratorium, or similar laws relating to creditor’s rights generally.

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 or in such form generated by Borrower and reasonably acceptable to Silicon; 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. Loan requests received after 12:00 Noon will not be considered by Silicon until the next Business Day. Together with each such schedule, or later if requested by Silicon, Borrower shall furnish Silicon with copies (or, at Silicon’s request, originals if reasonably deemed necessary by Silicon for perfection or collection) of all contracts, orders, invoices, and other similar documents, and all original 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 in such form and at such intervals as Silicon shall reasonably request. In addition, Borrower shall deliver to Silicon, on its request, the originals of all instruments, chattel paper, security agreements, guarantees and other documents and property evidencing or securing any Accounts, in the same form as received, with all necessary endorsements and copies of all credit memos.

4.4 Collection of Accounts. Borrower shall cause the Account Debtors to remit all Accounts to Silicon and Silicon shall hold all payments on, and proceeds of, Accounts in a lockbox account, or such other “blocked account” as Silicon may reasonably specify, pursuant to a blocked account agreement in such form as Silicon may reasonably specify. All such payments on, and proceeds of, Accounts shall be applied to the Obligations in such order as Silicon shall determine. Silicon or its designee may, at any time, notify Account Debtors that Silicon has been granted a security interest in the Accounts. Notwithstanding the foregoing, if Borrower is on “streamline reporting status” pursuant to Section 6 of the Schedule hereto, funds received by Silicon in the lockbox account or such other blocked account will not be applied to the Obligations and will be transferred by Silicon to an operating account of Borrower maintained at Silicon.

4.5 Remittance of Proceeds. So long as this Agreement has not been terminated or any Obligations are outstanding, all proceeds arising from the disposition of any Collateral shall not be commingled with any of Borrower’s other funds or property and will be held separate and apart from such other funds and property in an express trust for Silicon and 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 segregate and remit to Silicon the proceeds of (i) the sale of worn out or obsolete Equipment disposed of by Borrower in good faith in an arm’s length transaction for an aggregate purchase price of $50,000 or less (for all such transactions in any fiscal year) or (ii) the sale of worn out or obsolete Inventory disposed of by Borrower in good faith in an arm’s length transaction for an aggregate purchase price of $250,000 or less (for all such transactions in any fiscal year). Nothing in this Section 4.5 limits the restrictions on disposition of Collateral set forth elsewhere in this Agreement.

4.6 Disputes. Borrower shall notify Silicon promptly of all material disputes or claims relating to Accounts in an amount of more than the lesser of (i) $50,000 or (ii) 10.0% of the subject Account for any individual dispute. 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. Silicon may, at any time after the occurrence and during the continuance of an Event of Default, settle or adjust disputes or claims directly with Account Debtors for amounts and upon terms which Silicon considers advisable in its reasonable judgment and, in all cases, Silicon shall credit Borrower’s Loan account with only the net amounts received by Silicon in payment of any Accounts.

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 (sending a copy to Silicon). 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 any Inventory, specifying the reason for such return, the location and condition of the returned Inventory, and on Silicon’s request deliver such returned Inventory to Silicon.

4.8 Verification. Silicon may, from time to time, verify directly with the respective Account Debtors in a commercially reasonable manner 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.

4.9 No Liability. If Silicon complies with reasonable banking practices and Section 9-207 of the Code, 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 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.

Section 5 ADDITIONAL DUTIES OF THE BORROWER.

5.1 Financial and Other Covenants. Borrower shall at all times comply with the financial and other covenants set forth in the Schedule.

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, which shall be utilized by Borrower for the repair or replacement of the Collateral or property with respect to which the insurance proceeds were paid. Silicon may require reasonable assurance that the insurance proceeds so

released will be so used. If Borrower fails to provide or pay for any insurance, Silicon may, but is not obligated to, obtain the same at Borrower’s expense. Borrower shall promptly deliver to Silicon copies of all material reports made to insurance companies.

5.3 Reports.

5.4 Access to Collateral, Books and Records. At reasonable times, and on one Business Day’s notice, Silicon, or its agents, shall have the right to inspect the Collateral, and the right to audit and copy Borrower’s books and records. Such audits shall be conducted no more often than once every three (3) months, provided no Event of Default has occurred and is continuing. Such audits shall be conducted no more often than once every twelve (12) months while Borrower is on “streamline reporting status” pursuant to Section 6 of the Schedule hereto, provided no Event of Default has occurred and is continuing. Notwithstanding anything to the contrary in this Section 5.4, while no Event of Default exists, Borrower will not be required to disclose or permit the examination or inspection of any document, information or other matter that (i) constitutes non-financial trade secrets or non-financial proprietary information, (ii) in respect of which disclosure to Silicon (or its representative) is then prohibited by applicable law or any agreement binding on Borrower as of the date hereof which has been disclosed to Silicon in writing, or (iii) is subject to attorney-client privilege. Silicon shall take reasonable steps to keep confidential all information obtained in any such inspection or audit, but Silicon shall have the right to disclose any such information to its auditors, regulatory agencies, and attorneys, and pursuant to any subpoena or other legal process. The foregoing inspections and audits shall be at Borrower’s expense and the charge therefor shall be $750 per person per day plus reasonable out-of-pocket expenses.

In no event shall Silicon’s rights under the foregoing power of attorney or any of Silicon’s other rights under this Agreement be deemed to indicate that Silicon is in control of the business, management or properties of Borrower.

7.5 Application of Proceeds. All proceeds realized as the result of any sale of the Collateral shall be applied by Silicon first to the reasonable costs, expenses, liabilities, obligations and attorneys’ fees incurred by Silicon in the exercise of its rights under this Agreement, second to the interest due upon any of the Obligations, and third to the principal of the Obligations, in such order as Silicon shall determine in its sole discretion. 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. In addition to the rights and remedies set forth in this Agreement, Silicon shall have all the other rights and remedies accorded a secured party under the Code and under all other applicable laws, and under any other instrument or agreement now or in the future entered into between Silicon and Borrower, and all of such rights and remedies are cumulative and none is exclusive. Exercise or partial exercise by Silicon of one or more of its rights or remedies shall not be deemed an election, nor bar Silicon from subsequent exercise or partial exercise of any other rights or remedies.

9.1 Interest Computation; Float Charge. In computing interest on the Obligations, all Payments received after 12:00 Noon on any day shall be deemed received on the next Business Day. In addition, except when Borrower is on “streamline reporting status” pursuant to Section 6 of the Schedule hereto, Silicon shall be entitled to charge Borrower a “float” charge in an amount equal to two Business Days interest, at the interest rate applicable to the Loans, on all Payments received by Silicon. Said float charge is not included in interest for purposes of computing Minimum Monthly Interest (if any) under this Agreement. The float charge for each month shall be payable on the last day of the month. 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, if not paid as and when due, charge them to Borrower’s Loan account, 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 sixty (60) days after each 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 regular first-class mail, or certified mail return receipt requested, addressed to Silicon or Borrower at the addresses shown in the preamble or heading, respectively, to this Agreement, or at any other address designated in writing by one party to the other party. Notices to Silicon shall be directed to the Commercial Finance Division, to the attention of the Division Manager or the Division Credit Manager.

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 present or future agreement between Borrower and Silicon 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 agreement now or in the future executed by Borrower and delivered to Silicon 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. To the extent permitted by law, Borrower waives the benefit of all statutes of limitation relating to any of the Obligations or this Agreement or any document related hereto, and to the extent permitted by law, 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’ 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, claims, debts, liabilities, demands, obligations, actions, causes of action, penalties, costs and expenses proximately caused by the indemnitee’s own gross negligence or willful misconduct. 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

In satisfying Borrower’s obligation hereunder to reimburse Silicon for attorneys fees, Borrower may, for convenience, issue checks directly to Silicon’s attorneys, ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇▇▇, LLP, but Borrower acknowledges and agrees that ▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇▇▇, 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, Silicon 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 Section 9.12 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 Agreement or any Loan Document 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 the earlier to occur of (i) one year after the discovery of the act, occurrence or omission upon which such claim or cause of action is based, and the service of a summons and complaint on an officer of Silicon, or on any other person authorized to accept service on behalf of Silicon, within thirty (30) days thereafter, or (ii) three years from the date of this Agreement, or if later, one year from the Maturity Date of this Agreement if such Maturity Date is extended pursuant to an amendment or modification of this Agreement. Borrower agrees that such period is a reasonable and sufficient time for Borrower to investigate and act upon any such claim or cause of action. The 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 Agreement or any other present or future agreement.

9.16 Section Headings; Construction. Section 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 section, and the headings shall not be used in any manner to construe, limit, define or interpret any term or provision of this Agreement. The term “including”, whenever used in this Agreement, shall mean “including (but not limited to)”.

9.19 Confidentiality. In handling any confidential information, Silicon shall exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (i) to Silicon’s subsidiaries or affiliates in connection with their present or prospective business relations with Borrower; (ii) to prospective transferees or purchasers of any interest in the Loans (provided, however, Silicon shall use commercially reasonable efforts in obtaining such prospective transferee’s or purchaser’s agreement to the terms of this provision); (iii) as required by law, regulation, subpoena, or other order; (iv) as required in connection with Silicon’s examination or audit; and (v) as Silicon considers appropriate in exercising remedies under this Agreement.
