The Existing Loan Agreement provided for loans up to the principal amount of Five Million Dollars ($5,000,000) and an Equipment Term Loan in the principal amount of Two Million Dollars ($2,000,000). The Borrower and Bank have agreed to replace the Existing Loan Agreement with this Agreement and to cause all Obligations owed under the Existing Loan Agreement as of the date hereof to become Advances hereunder upon the terms and conditions as more fully set forth herein.

1. ACCOUNTING AND OTHER TERMS

Accounting terms not defined in this Agreement will be construed following GAAP. Calculations and determinations must be made following GAAP. The term “financial statements” includes the notes and schedules. The terms “including” and “includes” always mean “including (or includes) without limitation,” in this or any Loan Document.

2. LOAN AND TERMS OF PAYMENT

2.1 Promise to Pay.

Borrower promises to pay Bank the unpaid principal amount of all Credit Extensions and interest on the unpaid principal amount of the Credit Extensions.

2.1.1 Revolving Advances.

(a) Bank will make Advances not exceeding the Committed Revolving Line minus (i) the amount of all outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit), minus (ii) all amounts utilized under the Cash Management Services Sublimit and minus (iii) the FX Reserve. Amounts borrowed under this Section may be repaid and reborrowed during the term of this Agreement.

(b) To obtain an Advance, Borrower must notify Bank by facsimile or telephone by 3:00 p.m. Pacific time on the Business Day the Advance is to be made. Borrower must promptly confirm the notification by delivering to Bank the Loan Payment/Advance Request Form attached as Exhibit B (the “Payment/Advance Form”). Bank will credit Advances to Borrower’s deposit account. Bank may make Advances under this Agreement based on instructions from a Responsible Officer or his or her designee or without instructions if the Advances are necessary to meet Obligations which have become due. Bank may rely on any telephone notice given by a person whom Bank reasonably believes is a Responsible Officer or designee. Borrower will indemnify Bank for any loss Bank suffers due to such reliance.

(c) The Committed Revolving Line terminates on the Revolving Maturity Date, when all Advances are immediately payable.

(d) Bank’s obligation to lend the undisbursed portion of the Obligations will terminate if, in Bank’s sole discretion, there has been a material adverse change in the general affairs, management, results of operation, condition (financial or otherwise) or the prospect of repayment of the Obligations, or there has been any material adverse deviation by Borrower from the most recent business plan of Borrower presented to and accepted by Bank prior to the execution of this Agreement.

2.1.2 Letters of Credit Sublimit.

Bank will issue or have issued letters of credit (each a “Letter of Credit” and collectively the “Letters of Credit”) for Borrower’s account not exceeding (i) the Committed Revolving Line, minus (ii) the outstanding principal balance of the Advances minus the Cash Management Sublimit, minus the FX

Reserve; however, the face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit), together with all outstanding Advances, all amounts for services utilized under the Cash Management Services Sublimit and the FX Reserve, may not at any time exceed Fifteen Million Dollars ($15,000,000). Each Letter of Credit will have an expiry date of no later than one hundred eighty (180) days after the Revolving Maturity Date, but Borrower’s obligations to reimburse Bank under the Letters of Credit will be secured by cash on terms acceptable to Bank at any time after the Revolving Maturity Date if the term of this Agreement is not extended by Bank. Borrower agrees to execute any further documentation in connection with the Letters of Credit as Bank may reasonably request. Prior to or simultaneously with the opening of each Letter of Credit, Borrower shall pay to Bank, a letter of credit fee (each a “Letter of Credit Fee” and collectively the “Letter of Credit Fees”) in an amount equal to one percent (1%) per annum of the face amount of the Letter of Credit. Such Letter of Credit Fees shall be paid in advance upon the issuance of the Letter of Credit and upon each anniversary thereof, if any. In addition, Borrower shall pay to Bank any and all additional issuance, negotiation, processing, transfer or other fees to the extent and as and when required by Bank.

2.1.3 Foreign Exchange Sublimit.

If there is availability under the Committed Revolving Line, then Borrower may enter in foreign exchange forward contracts with the Bank under which Borrower commits to purchase from or sell to Bank a set amount of foreign currency more than one business day after the contract date (the “FX Forward Contract”). Bank will subtract 10% of each outstanding FX Forward Contract from the foreign exchange sublimit which, together with all outstanding Advances, all outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit) and all amounts utilized under the Cash Management Services Sublimit, shall not exceed Fifteen Million Dollars ($15,000,000) (the “FX Reserve”). The total FX Forward Contracts at any one time may not exceed 10 times the amount of the FX Reserve. Bank may terminate the FX Forward Contracts if an Event of Default occurs.

2.1.4 Cash Management Services Sublimit.

Borrower may use up to Fifteen Million Dollars ($15,000,000), minus all outstanding Advances, minus all outstanding Letters of Credit, (including drawn but unreimbursed Letters of Credit), minus the FX Reserve, (the “Cash Management Services Sublimit”) for Bank’s Cash Management Services, which may include merchant services, direct deposit of payroll, business credit card, and check cashing services identified in various cash management services agreements related to such services (the “Cash Management Services”). Such aggregate amounts utilized under the Cash Management Services Sublimit will at all times reduce the amount otherwise available to be borrowed under the Committed Revolving Line. Any amounts Bank pays on behalf of Borrower or any amounts that are not paid by Borrower for any Cash Management Services will be treated as Advances under the Committed Revolving Line and will accrue interest at the rate for Advances.

2.2 Interest Rate, Payments.

Interest Rate. Advances accrue interest on the outstanding principal balance at a floating per annum rate of interest equal to the Prime Rate. After an Event of Default, Obligations accrue interest at three percent (3%) above the rate effective immediately before the Event of Default. The interest rate increases or decreases when the Prime Rate changes. Interest is computed on a 360-day year for the actual number of days elapsed.

(a) Payments. Interest due on the Committed Revolving Line is payable on the first (1st) day of each month. Bank may debit any of Borrower’s deposit accounts including Account Number              for principal and interest payments owing or any amounts Borrower owes Bank. Bank will promptly notify Borrower when it debits Borrower’s accounts. These debits are not a set-off. Payments received after 12:00 Noon 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 accrue.

2.3 Fees.

Borrower will pay all Bank Expenses (including reasonable attorneys’ fees and reasonable expenses) incurred through and after the date of this Agreement, which Bank Expenses shall be payable immediately upon request by Bank.

(c) Settle or adjust disputes and claims directly with account debtors for amounts, on terms and in any order that Bank considers advisable;

(d) Make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral. Borrower will assemble the Collateral if Bank requires and make it

8

available as Bank designates. Bank may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies;

(e) Apply to the Obligations any (i) balances and deposits of Borrower with Bank or its Affiliate it holds, or (ii) amount held by Bank owing to or for the credit or the account of Borrower;

(f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Bank is granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s labels, Patents, Copyrights, Mask Works, rights of use of any name, trade secrets, trade names, Trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit;

(g) Bank may place a “hold” on any account maintained with Bank and deliver a notice of exclusive control, any entitlement order, or other directions or instructions pursuant to any control agreement or similar agreements providing control of any Collateral; and

(h) Dispose of the Collateral according to the Code.

9.2 Power of Attorney.

Effective only when an Event of Default occurs and continues, Borrower irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower’s name on any checks or other forms of payment or security; (ii) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against account debtors, (iii) make, settle, and adjust all claims under Borrower’s insurance policies; (iv) settle and adjust disputes and claims about the Accounts directly with account debtors, for amounts and on terms Bank determines reasonable; and (v) transfer the Collateral into the name of Bank or a third party as the Code permits. Bank may exercise the power of attorney to sign Borrower’s name on any documents necessary to perfect or continue the perfection of any security interest regardless of whether an Event of Default has occurred. Bank’s appointment as Borrower’s attorney in fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations have been fully repaid and performed and Bank’s obligation to provide Credit Extensions terminates.

9.3 Accounts Collection.

When an Event of Default occurs and continues, Bank may notify any Person owing Borrower money of Bank’s security interest in the funds and verify the amount of the Account. Borrower must collect all payments in trust for Bank and, if requested by Bank, immediately deliver the payments to Bank in the form received from the account debtor, with proper endorsements for deposit.

9.4 Bank Expenses.

If Borrower fails to pay any amount or furnish any required proof of payment to third persons, Bank may make all or part of the payment or obtain insurance policies required in Section 6.5, and take any action under the policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and immediately due and payable, bearing interest at the then applicable rate and secured by the Collateral. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default.

9.5 Bank’s Liability for Collateral.

If Bank complies with reasonable banking practices and the Code, it is not liable 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 Remedies Cumulative.

Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements are cumulative. Bank has all rights and remedies provided under the Code, by law, or in equity. Bank’s exercise of one right or remedy is not an election, and Bank’s waiver of any Event of

9

Default is not a continuing waiver. Bank’s delay is not a waiver, election, or acquiescence. No waiver is effective unless signed by Bank and then is only effective for the specific instance and purpose for which it was given.

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 Bank on which Borrower is liable.
