SECTION 2

LOAN; PAYMENT TERMS

2.1 Promise to Pay. Borrower hereby unconditionally promises to pay Lender the outstanding principal amount of all Loans and accrued and unpaid interest thereon as and when due in accordance with this Agreement.

2.1.1 Revolving Line of Credit.

(a) Availability. Subject to the terms and conditions of this Agreement, Lender shall make Advances not exceeding the Revolving Availability Amount. Each Advance will, at Borrower’s option in accordance with the terms of this Agreement, be either in the form of a Prime Rate Advance or a LIBOR Advance. No more than six (6) LIBOR Advances may be outstanding at any time. Amounts borrowed hereunder may be repaid and, prior to the Revolving Line Maturity Date, reborrowed, subject to the applicable terms and conditions precedent herein. The credit facility described in this Section 2.1.1 is referred to as the “Revolving Line of Credit”.

(b) Termination; Repayment. The Revolving Line of Credit terminates on the Revolving Line Maturity Date, when the principal amount of all Advances, the unpaid interest thereon, and all other Obligations relating to the Revolving Line of Credit shall be immediately due and payable.

2.1.2 Letters of Credit Sublimit.

(a) As part of the Revolving Line of Credit, Lender shall issue or have issued Letters of Credit for Borrower’s account. Such aggregate amounts utilized hereunder shall at all times reduce the amount otherwise available for Advances under the Revolving Line of Credit. The amount of the Letters of Credit outstanding at any one time (including the drawn and unreimbursed amounts of the Letters of Credit) may not exceed the Letter of Credit Availability Amount. If, on the Revolving Line Maturity Date, there are any outstanding Letters of Credit, then on such date Borrower shall provide to Lender cash collateral in an amount equal to 101% of the face amount of all such Letters of Credit plus all interest, fees, and costs due or to become due in connection therewith (as estimated by Lender in its good faith business judgment), to secure all of the Obligations relating to said Letters of Credit. All Letters of Credit shall be in form and substance acceptable to Lender in its sole discretion and shall be subject to the terms and conditions of Lender’s standard application and letter of credit agreement, the forms of which may vary from time to time although a sample form is attached hereto as Exhibit E (the “Letter of Credit Application”). Borrower agrees to execute any further documentation in connection with the Letters of Credit as Lender may reasonably request. Borrower further agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guarantied by Lender and opened for Borrower’s account or by Lender’s interpretations of any Letter of Credit issued by Lender for Borrower’s account and Borrower understands and agrees that Lender 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.

(b) Except as provided in the following sentence, all Letters of Credit will have an initial maturity of no more than one year, renewable annually, if timely requested by Borrower and permitted by Lender in Lender’s sole discretion, for additional one-year periods up to a total maximum maturity of five years. A Letter of Credit that is not subject to annual renewal at Lender’s discretion may have a maturity longer than one year and less than or equal to five years, but the aggregate face amount of all such Letters of Credit (including the accrued and unreimbursed amounts of such Letters of Credit) may not exceed $5,000,000.

(c) The obligation of Borrower to immediately reimburse Lender for drawings made under Letters of Credit shall be absolute, unconditional, and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement, such Letters of Credit, and the Letter of Credit Application.

(d) Borrower may request that Lender issue a Letter of Credit payable in a Foreign Currency. If a demand for payment is made under any such Letter of Credit, Lender shall treat such demand as an Advance to Borrower of the equivalent of the amount thereof (plus fees and charges in connection therewith such as wire, cable, SWIFT or similar charges) in Dollars at the then-prevailing rate of exchange in New York, New York, for sales of the Foreign Currency for transfer to the country issuing such Foreign Currency.

(e) Borrower agrees that (i) any sum drawn under a Letter of Credit that has not been immediately repaid when due may, at the option of Lender, be deemed an Advance and added to the principal amount outstanding under this Agreement and (ii) that such Advance will bear interest at a floating rate equal to 3.00 percentage points over the Index, which interest shall be payable monthly in accordance with Section 2.3(f) below.

2.2 Overadvances. If at any time the Loans under Section 2.1.1 exceed the Revolving Availability Amount, then Borrower must immediately pay to Lender in cash such excess and Lender will apply such cash amount to repay outstanding Advances. If at any time the aggregate amount of all Loans outstanding, including drawn and undrawn Letters of Credit, exceeds the Letter of Credit Availability Amount, Borrower must immediately pay to Lender in cash such excess amount (the “Overadvance Amount”). Lender will then apply the Overadvance Amount to repay outstanding Advances so that the outstanding Advances are no more than the Revolving Availability Amount and deposit the remaining portion of the Overadvance Amount in a blocked, segregated deposit account as security for the Obligations, including Contingent Obligations. Borrower may apply, no more often than once per calendar month, for a return of the cash on deposit in the blocked account and Lender must return the portion of such cash amount that exceeds the Overadvance Amount, as the Overadvance Amount is calculated by Lender as of the time of Borrower’s application.

2.3 Payment of Interest on the Loans.

(a) Interest Rate. Subject to Section 2.3(b) and unless otherwise stated, each Advance shall bear interest on the outstanding principal amount thereof from the date when made, continued or converted until paid in full at a rate per annum equal to the Index or the LIBOR Rate, as the case may be. Pursuant to the terms hereof, interest on each Advance shall be paid in arrears on each Interest Payment Date. Interest shall also be paid on the date of any prepayment of any Advance pursuant to this Agreement for the portion of any Advance so prepaid and upon payment (including prepayment) in full thereof. All accrued but unpaid interest on the Advances shall be due and payable on the Revolving Line Maturity Date.

(b) Default Rate. If any Event of Default shall occur, including failure to pay upon final maturity, Lender, at its option, may, if permitted under applicable law, increase the interest rate otherwise payable hereunder by 3.000 percentage points. Specifically and without limiting the previous sentence, on and after the expiration of any Interest Period applicable to any LIBOR Advance outstanding on the date of occurrence of an Event of Default or acceleration of the Obligations, the Effective Amount of such LIBOR Advance shall, during the continuance of such Event of Default or after acceleration, bear interest at a rate per annum equal to the Index plus 5.000 percentage points. The interest rate will not exceed the maximum rate permitted by applicable law (the “Default Rate”). Payment or acceptance of the increased interest rate provided in this Section 2.3(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Lender.

(c) Adjustment to Interest Rate. Changes to the interest rate of any Loan based on changes to the Index shall be effective on the effective date of any change to the Index and to the extent of any such change.

(d) Interest Rate Basis. The annual interest rate under this Agreement is computed on a 365/360 basis; that is, by applying the ratio of the annual interest rate over a year of 360 days, multiplied by the outstanding principal balance, multiplied by the actual number of days the principal balance is outstanding.

(e) Debit of Accounts. Lender may debit any of Borrower’s deposit accounts, including the Designated Deposit Account, for principal and interest payments or any other amounts Borrower owes Lender if not paid in full when due, including interest, fees, and costs due or to become due in connection with any Letter of Credit. These debits shall not constitute a set-off.

(f) Payments. Unless otherwise provided, interest is payable monthly on the first calendar day of each month. Payments of principal and/or interest received after 12:00 p.m. Pacific time are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest, as applicable, shall continue to accrue.

2.4 Fees. Borrower shall pay to Lender:

(a) Commitment Fee. A fully earned, non-refundable commitment fee of $37,500 equal to one quarter of one percent (0.25%) of the Total Availability Amount, on the date hereof; and

(b) Letter of Credit Fee. Lender’s customary fees and expenses for the issuance or renewal of Letters of Credit, including, without limitation, local issuance fees, a Letter of Credit Fee of one percent (1.00%) per annum of the face amount of each Letter of Credit issued, upon the issuance, each anniversary of the issuance, and the renewal of such Letter of Credit by Lender; and

(c) Late Charge. If a payment is 15 days or more late, Borrower will be charged 5.000 % of the regularly scheduled payment or $35.00, whichever is greater.

(d) Dishonored Item Fee. Borrower will pay a fee to Lender of $35.00 if Borrower makes a payment on any Loan and the check or preauthorized charge with which Borrower pays is later dishonored.

(e) Lender Expenses. All Lender Expenses (including reasonable attorneys’ fees and expenses, plus expenses, for documentation and negotiation of this Agreement) incurred through and after the date hereof, when due.

(b) the representations and warranties in Section 5 shall be true in all material respects on the date of the Notice of Borrowing / Letter of Credit Application and on the Funding Date of each Loan; provided, however, that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof; and provided, further that those representations and warranties expressly referring to a specific date shall be true, accurate and complete in all material respects as of such date, and no Event of Default shall have occurred and be continuing or result from the Loan. Each Loan is Borrower’s representation and warranty on that date that the representations and warranties in Section 5 remain true in all material respects; provided, however, that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by materiality in the text thereof; and provided, further that those representations and warranties expressly referring to a specific date shall be true, accurate and complete in all material respects as of such date; and

3.3 Covenant to Deliver. Borrower agrees to deliver to Lender each item required to be delivered to Lender under this Agreement as a condition to any Loan. Borrower expressly agrees that the extension of a Loan

prior to the receipt by Lender of any such item shall not constitute a waiver by Lender of Borrower’s obligation to deliver such item, and any such extension in the absence of a required item shall be in Lender’s sole discretion.

3.4 Procedure for the Borrowing of Advances. Subject to the prior satisfaction of all other applicable conditions to the making of an Advance set forth in this Agreement, each Advance shall be made upon Borrower’s irrevocable written notice delivered to Lender in the form of a Notice of Borrowing, each executed by a Responsible Officer of Borrower or his or her designee or without instructions if the Advances are necessary to meet Obligations which have become due. Lender may rely on any telephone notice given by a person whom Lender believes is a Responsible Officer or designee. Borrower will indemnify Lender for any loss Lender suffers due to such reliance. Such Notice of Borrowing must be received by Lender prior to 11:00 a.m. Pacific time, (i) at least three (3) Business Days prior to the requested Funding Date, in the case of LIBOR Advances, and (ii) at least one (1) Business Day prior to the requested Funding Date, in the case of Prime Rate Advances, specifying:

(a) whether the Advance is to be comprised of LIBOR Advances or Prime Rate Advances

(b) the amount of the Advance, which, if such Advance is the initial LIBOR Advance or the initial Prime Rate Advance, such Advance must be in an aggregate minimum principal amount of $500,000 or in any integral multiple of $100,000 in excess thereof; otherwise the minimum Advance amount is $100,000 or in any integral multiple of $100,000 in excess thereof;

(d) the duration of the Interest Period applicable to any such LIBOR Advances included in such notice; provided that if the Notice of Borrowing shall fail to specify the duration of the Interest Period for any Advance comprised of LIBOR Advances, such Interest Period shall be one (1) month.

The proceeds of all such Advances will then be made available to Borrower on the Funding Date by Lender by transfer to the Designated Deposit Account and, subsequently, by wire transfer to such other account as Borrower may instruct in the Notice of Borrowing. No Advances shall be deemed made to Borrower, and no interest shall accrue on any such Advance, until the related funds have been deposited in the Designated Deposit Account.

3.5 Special Provisions Governing LIBOR Advances. Notwithstanding any other provision of this Agreement to the contrary, the following provisions shall govern with respect to LIBOR Advances as to the matters covered:

(a) Determination of Applicable Interest Rate. As soon as practicable on each Interest Rate Determination Date, Lender shall determine (which determination shall, absent manifest error in calculation, be final, conclusive and binding upon all parties) the interest rate that shall apply to the LIBOR Advances for which an interest rate is then being determined for the applicable Interest Period and shall promptly give notice thereof (in writing or by telephone confirmed in writing) to Borrower.

(b) Inability to Determine Applicable Interest Rate. In the event that Lender shall have determined (which determination shall be final and conclusive and binding upon all parties hereto), on any Interest Rate Determination Date with respect to any LIBOR Advance, that by reason of circumstances affecting the London interbank market adequate and fair means do not exist for ascertaining the interest rate applicable to such Advance on the basis provided for in the definition of Base LIBOR, Lender shall on such date give notice (by facsimile or by telephone confirmed in writing) to Borrower of such determination, whereupon (i) no Advances may be made as, or converted to, LIBOR Advances until such time as Lender notifies Borrower that the circumstances giving rise to such notice no longer exist, and (ii) any Notice of Borrowing or Notice of Conversion/Continuation given by Borrower with respect to Advances in respect of which such determination was made shall be deemed to be rescinded by Borrower.

(c) Compensation for Breakage or Non-Commencement of Interest Periods. Borrower shall compensate Lender, upon written request by Lender (which request shall set forth the manner and method of

computing such compensation), for all reasonable losses, expenses and liabilities, if any (including any interest paid by Lender to lenders of funds borrowed by it to make or carry its LIBOR Advances and any loss, expense or liability incurred by Lender in connection with the liquidation or re-employment of such funds) such that Lender may incur: (i) if for any reason (other than a default by Lender or due to any failure of Lender to fund LIBOR Advances due to impracticability or illegality under Sections 3.6(d) and 3.6(e)) a borrowing or a conversion to or continuation of any LIBOR Advance does not occur on a date specified in a Notice of Borrowing or Notice of Conversion/Continuation, as the case may be, or (ii) if any principal payment of any of its LIBOR Advances occurs on a date prior to the last day of an Interest Period applicable to that Advance.

(d) Assumptions Concerning Funding of LIBOR Advances. Calculation of all amounts payable to Lender under this Section 3.5 and otherwise under this Agreement shall be made as though Lender had actually funded each of the relevant LIBOR Advances through the purchase of a Eurodollar deposit bearing interest at the rate obtained pursuant to the definition of LIBOR Rate in an amount equal to the amount of such LIBOR Advance and having a maturity comparable to the relevant Interest Period; provided, however, that Lender may fund each of its LIBOR Advances in any manner it sees fit and the foregoing assumptions shall be utilized only for the purposes of calculating amounts payable under this Section 3.5 and otherwise under this Agreement.

(e) LIBOR Advances After Default. After the occurrence and during the continuance of an Event of Default, (i) Borrower will have no right to have an Advance be made or continued as, or converted to, a LIBOR Advance after the expiration of any Interest Period then in effect for such Advance and (ii) subject to the provisions of Section 3.5(c), any Notice of Conversion/Continuation given by Borrower with respect to a requested conversion/continuation that has not yet occurred shall be deemed to be rescinded by Borrower and be deemed a request to convert or continue Advances referred to therein as Prime Rate Advances.

3.6 Additional Requirements/Provisions Regarding LIBOR Advances.

(a) If for any reason (including voluntary or mandatory prepayment or acceleration), Lender receives all or part of the principal amount of a LIBOR Advance prior to the last day of the Interest Period for such Advance, Borrower shall immediately notify Borrower’s account officer at Lender and, on demand by Lender, pay Lender the amount (if any) by which (i) the additional interest which would have been payable on the amount so received had it not been received until the last day of such Interest Period exceeds (ii) the interest which would have been recoverable by Lender by placing the amount so received on deposit in the certificate of deposit markets, the offshore currency markets, or United States Treasury investment products, as the case may be, for a period starting on the date on which it was so received and ending on the last day of such Interest Period at the interest rate determined by Lender in its reasonable discretion. Lender’s determination as to such amount shall be conclusive absent manifest error.

(b) Borrower shall pay Lender, upon demand by Lender, from time to time such amounts as Lender may determine to be necessary to compensate it for any costs incurred by Lender that Lender determines are attributable to its making or maintaining of any amount receivable by Lender hereunder in respect of any Advances relating thereto (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), in each case resulting from any Regulatory Change which:

(i) changes the basis of taxation of any amounts payable to Lender under this Agreement in respect of any Advances (other than changes which affect taxes measured by or imposed on the overall net income of Lender by the jurisdiction in which Lender has its principal office);

(ii) imposes or modifies any reserve, special deposit or similar requirements relating to any extensions of credit or other assets of, or any deposits with, or other liabilities of Lender (including any Advances or any deposits referred to in the definition of Base LIBOR); or

(iii) imposes any other condition affecting this Agreement (or any of such extensions of credit or liabilities).

Lender will notify Borrower of any event occurring after the date of this Agreement which will entitle Lender to compensation pursuant to this Section 3.6 as promptly as practicable after it obtains knowledge thereof and determines to request such compensation. Lender will furnish Borrower with a statement setting forth the basis and amount of each request by Lender for compensation under this Section 3.6. Determinations and allocations by Lender for purposes of this Section 3.6 of the effect of any Regulatory Change on its costs of maintaining its obligations to make Advances, of making or maintaining Advances, or on amounts receivable by it in respect of Advances, and of the additional amounts required to compensate Lender in respect of any Additional Costs, shall be conclusive absent manifest error.

(c) If Lender shall determine that the adoption or implementation of any applicable law, rule, regulation, or treaty regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank, or comparable agency charged with the interpretation or administration thereof, or compliance by Lender (or its applicable lending office) with any respect or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank, or comparable agency, has or would have the effect of reducing the rate of return on capital of Lender or any person or entity controlling Lender (a “Parent”) as a consequence of its obligations hereunder to a level below that which Lender (or its Parent) could have achieved but for such adoption, change, or compliance (taking into consideration policies with respect to capital adequacy) by an amount deemed by Lender to be material, then from time to time, within fifteen (15) days after demand by Lender, Borrower shall pay to Lender such additional amount or amounts as will compensate Lender for such reduction. A statement of Lender claiming compensation under this Section 3.6(c) and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive absent manifest error.

(d) If, at any time, Lender, in its sole and absolute discretion, determines that (i) the amount of LIBOR Advances for periods equal to the corresponding Interest Periods are not available to Lender in the offshore currency interbank markets, or (ii) LIBOR Rate does not accurately reflect the cost to Lender of lending the LIBOR Advances, then Lender shall promptly give notice thereof to Borrower. Upon the giving of such notice, Lender’s obligation to make the LIBOR Advances shall terminate; provided, however, Advances shall not terminate if Lender and Borrower agree in writing to a different interest rate applicable to LIBOR Advances.

(e) If it shall become unlawful for Lender to continue to fund or maintain any LIBOR Advances, or to perform its obligations hereunder, upon demand by Lender, Borrower shall prepay the Advances in full with accrued interest thereon and all other amounts payable by Borrower hereunder (including, without limitation, any amount payable in connection with such prepayment pursuant to Section 3.6(a)).

3.7 Conversion and Continuation Elections.

(a) So long as (i) no Event of Default exists; (ii) Borrower shall not have sent any notice of termination of this Agreement; and (iii) Borrower shall have complied with such customary procedures as Lender has established from time to time for Borrower’s requests for LIBOR Advances, Borrower may, upon irrevocable written notice to Lender,

(i) elect to convert on any Business Day, Prime Rate Advances in an amount equal to $100,000 or any integral multiple of $100,000 in excess thereof into LIBOR Advances;

(ii) elect to continue on any Interest Payment Date any LIBOR Advances maturing on such Interest Payment Date (or any part thereof in an amount equal to $100,000 or any integral multiple of $100,000 in excess thereof); provided, that if the aggregate amount of LIBOR Advances shall have been reduced, by payment, prepayment, or conversion of part thereof, to be less than $100,000, such LIBOR Advances shall automatically convert into Prime Rate Advances, and on and after such date the right of Borrower to continue such Advances as, and convert such Advances into, LIBOR Advances shall terminate; or

(iii) elect to convert on any Interest Payment Date any LIBOR Advances maturing on such Interest Payment Date (or any part thereof in an amount equal to $100,000 or any integral multiple of $100,000 in excess thereof) into Prime Rate Advances.

(b) Borrower shall deliver a Notice of Conversion/Continuation in accordance with Section 10 to be received by Lender prior to 11:00 a.m. Pacific time at least (i) three (3) Business Days in advance of the Conversion Date or Continuation Date, if any Advances are to be converted into or continued as LIBOR Advances; and (ii) one (1) Business Day in advance of the Conversion Date, if any Advances are to be converted into Prime Rate Advances, in each case specifying the:

(i) proposed Conversion Date or Continuation Date;

(ii) aggregate amount of the Advances to be converted or continued which, if any Advances are to be converted into or continued as LIBOR Advances, shall be in an aggregate minimum principal amount of $100,000 or in any integral multiple of $100,000 in excess thereof;

(iii) nature of the proposed conversion or continuation; and

(iv) duration of the requested Interest Period.

(c) If upon the expiration of any Interest Period applicable to any LIBOR Advances, Borrower shall have timely failed to select a new Interest Period to be applicable to such LIBOR Advances, then at Lender’s option, (i) Borrower shall be deemed to have selected the same Interest Period or a one-month Interest Period to apply to those LIBOR Advances or (ii) Borrower shall be deemed to have elected to convert such LIBOR Advances into Prime Rate Advances.

(d) Any LIBOR Advances shall, at Lender’s option, convert into Prime Rate Advances in the event that (i) an Event of Default shall exist, or (ii) the aggregate principal amount of the Prime Rate Advances which have been previously converted to LIBOR Advances, or the aggregate principal amount of existing Advances continued, as the case may be, at the beginning of an Interest Period shall at any time during such Interest Period exceed the Revolving Availability Amount. Borrower agrees to pay Lender, upon demand by Lender (or Lender may, at its option, charge the Designated Deposit Account or any other account Borrower maintains with Lender) any amounts required to compensate Lender for any loss (including loss of anticipated profits), cost, or expense incurred by Lender, as a result of the conversion of LIBOR Advances to Prime Rate Advances.

(e) Notwithstanding anything to the contrary contained herein, Lender shall not be required to purchase United States Dollar deposits in the London interbank market or other applicable LIBOR market to fund any LIBOR Advances, but the provisions hereof shall be deemed to apply as if Lender had purchased such deposits to fund the LIBOR Advances.

SECTION 4

4.1 Grant of Security Interest.

The Accounts are bona fide, existing obligations of the Account Debtors.

The Collateral is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the Diligence Certificate. None of the components of the Collateral shall be maintained at locations other than as provided in the Diligence Certificate or as Borrower has given Lender notice pursuant to Section 7.2.

Borrower is the sole owner of its intellectual property, except for non-exclusive licenses granted to its customers in the ordinary course of business. Each patent is valid and enforceable, and no part of the intellectual property has been judged invalid or unenforceable, in whole or in part, and to the best of Borrower’s knowledge, no claim has been made that any part of the intellectual property violates the rights of any third party except to the extent such claim could not reasonably be expected to have a material adverse effect on Borrower’s business. Except as noted on the Diligence Certificate, Borrower is not a party to, nor is bound by, any material license or other agreement with respect to which Borrower is the licensee (a) that prohibits or otherwise restricts Borrower from granting a security interest in Borrower’s interest in such license or agreement or any other property, or (b) for which a default under or termination of could interfere with the Lender’s right to sell any Collateral.

Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations T and U of the Federal Reserve Board of Governors). Borrower has complied in all material respects with the Federal Fair Labor Standards Act. Neither Borrower nor any of its Subsidiaries is a “holding company” or an “affiliate” of a “holding company” or a “subsidiary company” of a “holding company” as each term is defined and used in the Public Utility Holding Company Act of 2005. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be expected to have a material adverse effect on its business. None of Borrower’s or any of its Subsidiaries’ properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing, treating, or transporting any hazardous substance other than legally.

Borrower has paid all amounts necessary to fund all

present pension, profit sharing and deferred compensation plans in accordance with their terms, and Borrower has not withdrawn from participation in, and has not permitted partial or complete termination of, or permitted 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.

5.9 Use of Proceeds. Borrower shall use the proceeds of the Loans for purposes of issuing standby letters of credit, working capital and funding of its general business requirements and not for personal, family or household purposes.

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

(i) exercise all rights and remedies available to Lender under the Loan Documents or at law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof).

9.2 Power of Attorney. Borrower hereby irrevocably appoints Lender as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s name on any checks or other forms of payment or security; (b) sign Borrower’s name on any invoice or xxxx of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts and on terms Lender determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of Lender or a third party as the Code permits. Borrower hereby appoints Lender as its lawful attorney-in-fact to sign Borrower’s name on any documents necessary to perfect or continue the perfection of Lender’s security interest in the Collateral regardless of whether an Event of Default has occurred until all Obligations have been satisfied in full and Lender is under no further obligation to make Loans hereunder. Lender’s foregoing appointment as Borrower’s attorney in fact, and all of Lender’s rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Lender’s obligation to provide Loans terminates.

9.3 Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.4 or fails to pay any premium thereon or fails to pay any other amount which Borrower is obligated to pay under this Agreement or any other Loan Document, Lender may obtain such insurance or make such payment, and all amounts so paid by Lender are Lender Expenses and immediately due and payable, bearing interest at the then highest applicable rate, and secured by the Collateral. Lender will make reasonable efforts to provide Borrower with notice of Lender obtaining such insurance at the time it is obtained or within a reasonable time thereafter. No payments by Lender are deemed an agreement to make similar payments in the future or Lender’s waiver of any Event of Default.

9.4 Application of Payments and Proceeds. Borrower shall have no right to specify the order or the accounts to which Lender shall allocate or apply any payments required to be made by Borrower to Lender or otherwise received by Lender under this Agreement when any such allocation or application is not specified

elsewhere in this Agreement. If an Event of Default has occurred and is continuing, Lender may apply any funds in its possession, whether from Borrower account balances, payments, proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations in such order as Lender shall determine in its sole discretion. Any surplus shall be paid to Borrower or other Persons legally entitled thereto; Borrower shall remain liable to Lender for any deficiency. If Lender, 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, Lender shall have the option, exercisable at any time, of either reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by Lender of cash therefor.

9.5 Lender’s Liability for Collateral. So long as Lender complies with reasonable banking practices regarding the safekeeping of the Collateral in the possession or under the control of Lender, Lender shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Borrower bears all risk of loss, damage or destruction of the Collateral.

9.6 No Waiver; Remedies Cumulative. Lender’s failure, at any time or times, to require strict performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Lender thereafter to demand strict performance and compliance herewith or therewith. No waiver hereunder shall be effective unless signed by Lender and then is only effective for the specific instance and purpose for which it is given. Lender’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Lender has all rights and remedies provided under the Code, by law, or in equity. Lender’s exercise of one right or remedy is not an election, and Lender’s waiver of any Event of Default is not a continuing waiver. Lender’s delay in exercising any remedy is not a waiver, election, or acquiescence.

9.7 Demand Waiver. Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Lender on which Borrower is liable.

SECTION 11

CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER

This Agreement and the Loan Documents will be governed by federal law applicable to Lender and, to the extent not preempted by federal law, the laws of the State of California, without regard to its conflicts of law provisions. Borrower and Lender each submit to the exclusive jurisdiction of the State and Federal courts in San Francisco County, California; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Lender from bringing suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other security for the Obligations, or to enforce a judgment or other court order in favor of Lender. Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Borrower hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in Section 10 of this Agreement and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid.

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND LENDER EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

SECTION 12

GENERAL PROVISIONS

12.1 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party. Borrower may not assign this Agreement or any rights or obligations under it without Lender’s prior written consent (which may be granted or withheld in Lender’s discretion). Lender has the right, without the consent of or notice to Borrower, to sell, transfer, negotiate, or grant participation in all or any part of, or any interest in, Lender’s obligations, rights, and benefits under this Agreement and the other Loan Documents.

12.2 Indemnification. Borrower agrees to indemnify, defend and hold Lender and its directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Lender harmless against: (a) all obligations, demands, claims, and liabilities (collectively, “Claims”) asserted by any other party in connection with the transactions contemplated by the Loan Documents; and (b) all losses or Lender Expenses incurred, or paid by

Lender from, following, or arising from transactions between Lender and Borrower (including reasonable attorneys’ fees and expenses), except for Claims and/or losses directly caused by Lender’s gross negligence or willful misconduct or breach of any material obligation under this Agreement or any other Loan Document.

12.3 Time of Essence. Time is of the essence for the performance of all Obligations in this Agreement.

12.4 Severability of Provisions. Each provision of this Agreement is severable from every other provision in determining the enforceability of any provision.

12.5 Amendments in Writing; Integration. All amendments to this Agreement must be in writing and signed by both Lender and Borrower. This Agreement and the Loan Documents represent the entire agreement about this subject matter and supersede prior negotiations or agreements. All prior agreements, understandings, representations, warranties, and negotiations between the parties about the subject matter of this Agreement and the Loan Documents merge into this Agreement and the Loan Documents.

12.6 Counterparts. This Agreement may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, are an original, and all taken together, constitute one Agreement.

12.7 Survival. All covenants, representations and warranties made in this Agreement continue in full force until this Agreement has terminated pursuant to its terms and all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied. The obligation of Borrower in Section 12.2 to indemnify Lender shall survive until the statute of limitations with respect to such claim or cause of action shall have run.

12.8 Confidentiality. In handling any confidential information, Lender shall exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (a) to Lender’s Subsidiaries or Affiliates; (b) to prospective transferees or purchasers of any interest in the Loans (provided, however, Lender shall use commercially reasonable efforts to obtain such prospective transferee’s or purchaser’s agreement to the terms of this provision); (c) as required by law, regulation, subpoena, or other order; (d) to Lender’s regulators or as otherwise required in connection with Lender’s examination or audit; and (e) as Lender considers appropriate in exercising remedies under this Agreement. Confidential information does not include information that either: (i) is in the public domain or in Lender’s possession when disclosed to Lender, or becomes part of the public domain after disclosure to Lender; or (ii) is disclosed to Lender by a third party, if Lender does not know that the third party is prohibited from disclosing the information.

12.9 Attorneys’Fees, Costs and Expenses. In any action or proceeding between Borrower and Lender arising out of or relating to the Loan Documents, the prevailing party shall be entitled to recover its reasonable attorneys’ fees and other costs and expenses incurred, in addition to any other relief to which it may be entitled.
