The parties agree as follows: 1 ACCOUNTING AND OTHER TERMS Accounting terms not defined in this Agreement shall 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. Capitalized terms in this Agreement shall have the meanings set forth in Section 13. 2 LOAN AND TERMS OF PAYMENT 2.1 Promise to Pay. Borrower hereby unconditionally promises to pay Bank the unpaid principal amount of all Credit Extensions and interest on the unpaid principal amount of the Credit Extensions as and when due in accordance with this Agreement. 2.1.1 Revolving Advances. (a) Availability. Bank shall make Advances not exceeding (i) the Committed Revolving Line minus (ii) the amount of all outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit), minus (iii) the FX Reserve, and minus (iv) the aggregate outstanding Advances hereunder. Amounts borrowed under this Section may be repaid and reborrowed during the term of this Agreement. (b) Borrowing Procedure. To obtain an Advance, Borrower must notify Bank by facsimile or telephone by 3:00 p.m. Eastern time on the Business Day the Advance is to be made. If such notification is by telephone, Borrower must promptly confirm the notification by delivering to Bank a completed Payment/Advance Form in the form attached as Exhibit B. Bank shall 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 believes is a Responsible Officer or designee. Borrower shall indemnify Bank for any loss Bank suffers due to such reliance. (c) Termination; Repayment. The Committed Revolving Line terminates on the Revolving Maturity Date, when the principal amount of all Advances and the unpaid interest thereon, shall be immediately due and payable. 2.1.2 Letters of Credit. (a) Bank shall issue or have issued Letters of Credit for Borrower's account not exceeding (i) the Committed Revolving Line minus (ii) the outstanding principal balance of any Advances, minus (iii) the amount of all Letters of Credit (including drawn but unreimbursed Letters of Credit), plus an amount equal to any Letter of Credit Reserves. The face amount of outstanding Letters of Credit (including drawn but unreimbursed Letters of Credit and any Letter of Credit Reserve) may not exceed $10,000,000.00. Each Letter of Credit shall have an expiry date no later than 180 days after the Revolving Maturity Date provided Borrower's Letter of Credit reimbursement obligation shall be secured by cash on terms acceptable to Bank on and after (i) the Revolving Maturity Date if the term of this Agreement is not extended by Bank, or (ii) the occurrence of an Event of Default hereunder. All Letters of Credit shall be, in form and substance, acceptable to Bank in its sole discretion and shall be subject to the terms and conditions of Bank's form of standard Application and Letter of Credit Agreement. Borrower agrees to execute any further documentation in connection with the Letters of Credit as Bank may reasonably request. (b) The obligation of Borrower to immediately reimburse Bank 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 and such Letters of Credit, under all circumstances whatsoever. Borrower shall indemnify, defend, protect, and hold Bank harmless from any loss, cost, expense or liability, including, without limitation, reasonable attorneys' fees, arising out of or in connection with any Letters of Credit. (c) Borrower may request that Bank issue a Letter of Credit payable in a currency other than United States Dollars. If a demand for payment is made under any such Letter of Credit, Bank shall treat such demand as an Advance to Borrower of the equivalent of the amount thereof (plus cable charges) in United States currency at the then prevailing rate of exchange in San Francisco, California, for sales of that other currency for cable transfer to the country of which it is the currency. (d) Upon the issuance of any letter of credit payable in a currency other than United States Dollars, Bank shall create a reserve (the "Letter of Credit Reserve") under the Committed Revolving Line for letters of credit against fluctuations in currency exchange rates, in an amount equal to ten percent (10%) of the face amount of such letter of credit. The amount of such reserve may be amended by Bank from time to time to account for fluctuations in the exchange rate. The availability of funds under the Committed Revolving Line shall be reduced by the amount of such reserve for so long as such letter of credit remains outstanding. 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 shall subtract 10% of each outstanding FX Forward Contract from the foreign exchange sublimit which is a maximum of $5,000,000 (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 Term Loan. (a) Bank shall advance, on behalf of Borrower, an amount equal to the Term Loan, on or before ten (10) days from the Closing Date. (b) Borrower shall pay (a) forty-eight (48) equal installments of principal each in the amount of $104,166.67 plus (b) monthly payments of interest (the "Term Loan Payment"). Each Term Loan Payment is payable on the Payment Date of each month during the term of the Term Loan. Borrower's final Term Loan Payment, due on Term Loan Maturity Date, shall include all outstanding Term Loan principal and accrued interest. 2.1.5 Undisbursed Credit Extensions. The Bank's obligation to lend the undisbursed portion of the Credit Extensions shall terminate if there has been a material adverse change in the general affairs, management, results of operation, condition (financial or otherwise) or the prospects of Borrower, whether or not arising from transactions in the ordinary course of business, 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. 2.2 Interest Rate; Payments. (a) Interest Rate. The principal amounts outstanding hereunder, including all amounts outstanding under the Committed Revolving Line and the Term Loan, shall accrue interest at a per annum rate equal to the Bank's Prime Rate. After an Event of Default, Obligations shall bear interest at three percent (3.0%) above the rate effective immediately before the Event of Default. The applicable interest rate hereunder shall increase or decrease when the Prime Rate changes. Interest is computed on the basis of a 360 day year for the actual number of days elapsed. 2 (b) Payments. Interest is payable on the Payment Date of each month. Bank may debit any of Borrower's deposit accounts including Account Number __________ for principal and interest payments or any amounts Borrower owes Bank. Bank shall promptly notify Borrower when it debits Borrower's accounts. These debits are not a set-off. Payments received after 12:00 noon Eastern 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. 2.3 Fees. Borrower shall pay to Bank: (a) Revolving Facility Fee. A fully earned, non-refundable facility fee of $70,312.00 due on the Closing Date; (b) Letter of Credit Fee.

Each Credit Extension is Borrower's representation and warranty on that date that the representations and warranties in Section 5 remain true. 4 CREATION OF SECURITY INTEREST 4.1 Grant of Security Interest. Borrower hereby grants Bank, to secure the payment and performance in full of all of the Obligations and the performance of each of Borrower's duties under the Loan Documents, a 3 continuing security interest in, and pledges and assigns to the Bank, the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. Borrower warrants and represents that the security interest granted herein shall be a first priority security interest in the Collateral. Bank may place a "hold" on any deposit account pledged as Collateral. Except as noted on the Perfection Certificate, Borrower is not a party to, nor is bound by, any license or other 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. Without prior consent from Bank, Borrower shall not enter into, or become bound by, any such license or agreement which is reasonably likely to have a material impact on Borrower's business or financial condition. Borrower shall take such steps as Bank 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 Bank 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. Borrower agrees that any disposition of the Collateral in violation of this Agreement, by either the Borrower or any other Person, shall be deemed to violate the rights of the Bank under the Code. If the Agreement is terminated, Bank's lien and security interest in the Collateral shall continue until Borrower fully satisfies its Obligations. If Borrower shall at any time, acquire a commercial tort claim, Borrower shall promptly notify Bank in a writing signed by Borrower of the brief details thereof and grant to Bank in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance satisfactory to Bank. 5 REPRESENTATIONS AND WARRANTIES Borrower represents and warrants as follows: 5.1 Due Organization and Authorization. Borrower and each Subsidiary is duly existing and in good standing in its state of formation and qualified and licensed to do business in, and in good standing in, any state in which the conduct of its business or its ownership of property requires that it be qualified except where the failure to do so could not reasonably be expected to cause a Material Adverse Change.

If the Borrower does not now have an organizational identification number, but later obtains one, Borrower shall forthwith notify the Bank of such organizational identification number.

When an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the following: 8 (a) Declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.6 occurs all Obligations are immediately due and payable without any action by Bank); (b) Stop advancing money or extending credit for Borrower's benefit under this Agreement or under any other agreement between Borrower and 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 shall assemble the Collateral if Bank requests and make it 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 it holds, or (ii) any 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; and (g) Dispose of the Collateral according to the Code. 9.2 Power of Attorney. Borrower hereby irrevocably appoints Bank as its lawful attorney-in-fact, to be effective upon the occurrence and during the continuance of an Event of Default, 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) settle and adjust disputes and claims about the Accounts directly with account debtors, for amounts and on terms Bank determines reasonable; (iv) make, settle, and adjust all claims under Borrower's insurance policies; and (v) transfer the Collateral into the name of Bank or a third party as the Code permits. Borrower hereby appoints Bank as its lawful attorney-in-fact 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 until all Obligations have been satisfied in full and Bank is under no further obligation to make Credit Extensions hereunder. Bank's foregoing 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. In the event that an Event of Default occurs and is continuing, Bank may notify any Person owing Borrower money of Bank's security interest in the funds and verify and/or collect the amount of the Account. After the occurrence of an Event of Default, any amounts received by Borrower shall be held in trust by Borrower for Bank, and, if requested by Bank, Borrower shall immediately deliver such receipts to Bank in the form received from the account debtor, with proper endorsements for deposit. 9.4 Bank Expenses. Any amounts paid by Bank as provided herein are Bank Expenses and are immediately due and payable, and shall bear interest at the then applicable rate and be secured by the Collateral. No payments by Bank shall be 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. So long as the Bank complies with reasonable banking practices regarding the safekeeping of collateral, the Bank 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 9 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.
