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.

All other terms contained in this Agreement, unless otherwise indicated, shall have the meanings provided by the Code, to the extent such terms are defined therein.

2                                         LOANS AND TERMS OF PAYMENT

2.1                               Promise to Pay.

Borrower hereby unconditionally promises to pay Lenders the unpaid principal amount of all Credit Extensions hereunder with all interest, fees and finance charges due thereon as and when due in accordance with this Agreement.

2.1.1                     Growth Capital Loan Facility.

(a)                                  Availability. Subject to the terms and conditions of this Agreement, Lenders agree, severally and not jointly, to lend to Borrower from time to time prior to the Growth Capital Commitment Termination Date, advances (each a “Growth Capital Advance” and collectively the “Growth Capital Advances”) in an aggregate amount not to exceed the Growth Capital Loan Commitment according to each Lender’s pro rata share of the Growth Capital Loan Commitment (based upon the respective Growth Capital Commitment Percentage of each Lender). When repaid, the Growth Capital Advances may not be re-borrowed. Lenders’ obligation to lend hereunder shall terminate on the earlier of (i) the occurrence and continuance of an Event of Default, or (ii) the Growth Capital Commitment Termination Date. Each Growth Capital Advance shall be in the amount of Five Million Dollars ($5,000,000). Subject to the satisfaction of the terms and conditions set forth in this Agreement, there shall be two (2) Growth Capital Advances, the Tranche A Growth Capital Advance and the Tranche B Growth Capital Advance.

(b)                                 Borrowing Procedure. To obtain a Growth Capital Advance, Borrower must notify Lenders by facsimile or telephone by 12:00 p.m. Pacific Time seven (7) Business Days prior to the date the Growth Capital Advance is to be made. If such notification is by telephone, Borrower must promptly confirm the notification by delivering to Lenders a completed Payment/Advance Form in the form attached as Exhibit B. In addition, a Note payable to each Lender in the form of Exhibit D

1

must be signed by a Responsible Officer or designee. On the Growth Capital Funding Date, each Lender shall credit and/or transfer (as applicable) to Borrower’s deposit account, an amount equal to its Growth Capital Commitment Percentage multiplied by the amount of the Growth Capital Advance; provided, however, Lenders may disburse the applicable portion of the Tranche A Growth Capital Advance directly to Comerica Bank and GE Capital to satisfy the conditions precedent listed in Sections 3.1 (d) and (e). Each Lender may make Growth Capital Advances under this Agreement based on instructions from a Responsible Officer or his or her designee or without instructions if the Growth Capital Advances are necessary to meet Obligations which have become due. Each Lender may rely on any telephone notice given by a person whom such Lender believes is a Responsible Officer or designee. Borrower shall indemnify each Lender for any loss Lender suffers due to such reliance.

2.2                               Termination of Commitment to Lend.

Each Lender’s obligation to lend the undisbursed portion of the Obligations shall terminate if, in such Lender’s sole discretion made in good faith, there has been a material adverse change in the general affairs, management, results of operation, condition (financial or otherwise) of Borrower 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 Lenders prior to the execution of this Agreement.

2.3                               Repayment of Credit Extensions on Growth Capital Advances.

(a)                                  Principal and Interest Payments on Payment Dates.

Commencing on the Growth Capital Amortization Date, Borrower shall make thirty-six (36) equal monthly payments of principal and interest which would fully amortize the outstanding Tranche A Growth Capital Advance as of the Growth Capital Amortization Date over the Growth Capital Repayment Period (individually, the “Growth Capital Scheduled Payment”, and collectively, “Growth Capital Scheduled Payments”) and on the first Business Day of each successive month and continuing thereafter during the Growth Capital Repayment Period on the first Business Day of each successive calendar month (each a “Growth Capital Scheduled Payment Date”). All unpaid principal and accrued interest is due and payable in full on the Growth Capital Maturity Date with respect to the Tranche A Growth Capital Advance.

(ii)                                  Tranche B Growth Capital Advance. For the Tranche B Growth Capital Advance, commencing on the first Business Day of the month following the month in which the Growth Capital Funding Date occurs (or commencing on the Growth Capital Funding Date if the Growth Capital Funding Date is the first Business Day of the month) and continuing thereafter on each Growth Capital Scheduled Payment Date, Borrower shall make thirty-six (36) equal monthly payments of principal and interest which would fully amortize the outstanding Tranche B Growth Capital Advance.

Interest is computed on the basis of a 360 day year of twelve 30-day months.

(ii)                                  Default Rate.

4                                         CREATION OF SECURITY INTEREST

4.1                               Grant of Security Interest. Borrower hereby grants to each Lender, 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 continuing security interest in, and pledges and assigns to each Lender 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. SVB may place a “hold” on any certificates of deposit or deposit or investment accounts pledged as Collateral to secure cash management services, corporate business credit cards or letters of credit separately issued or supplied by SVB under separate agreements between SVB and Borrower.

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 Lenders under the Code. If the Agreement is terminated, Lenders’ 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 Lenders in a writing signed by Borrower of the brief details thereof and grant to Lenders 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 Lenders.

Upon the indefeasible payment in full in cash of all Obligations under this Agreement and the termination of any obligation of any Lender to make Credit Extensions hereunder, Lenders shall execute and deliver to Borrower, at Borrower’s sole cost and expense, all documents and instruments as shall be reasonably necessary to evidence termination of the security interest in the Collateral created hereunder, including a UCC-3 Termination Statement.

4.2                               Authorization to File Financing Statements.

Borrower hereby authorizes Lenders to file financing statements, without notice to Borrower, with all appropriate jurisdictions, in order to perfect or protect Lenders’ interest or rights hereunder.

5                                         REPRESENTATIONS AND WARRANTIES

Borrower represents and warrants to each Lender 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. In connection with this Agreement, the Borrower delivered to Lenders a certificate signed by the Borrower and entitled “Perfection Certificate”. The Borrower represents and warrants to each Lender that: (a) the Borrower’s exact legal name is that indicated on the Perfection Certificate and on the signature page hereof; (b) the Borrower is an organization of the type, and is organized in the jurisdiction, set forth in the Perfection Certificate; (c) the Perfection Certificate accurately sets forth the Borrower’s organizational identification number or accurately states that the Borrower has none; (d) the Perfection Certificate accurately sets forth the Borrower ‘s place of business, or, if more than one, its chief executive office as well as the Borrower’s mailing address if different, and (e) all other information set forth on the Perfection Certificate pertaining to the Borrower is accurate and complete. If the Borrower does not now have an organizational identification number, but later obtains one, Borrower shall forthwith notify the Lenders of such organizational identification number.

The execution, delivery and performance of the Loan Documents have been duly authorized, and do not conflict with Borrower’s organizational documents, nor constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which or by which it is bound in which the default could reasonably be expected to cause a Material Adverse Change.

5.2                               Collateral.

Borrower has good title to the Collateral, free of Liens except Permitted Liens. Borrower has no deposit account, other than the deposit accounts with SVB and deposit accounts described in the Perfection Certificate delivered to Lenders in connection herewith. The Accounts are bona fide, existing obligations, and the service or property has been performed or delivered to the account debtor or its agent for immediate shipment to and unconditional acceptance by the account debtor. The Collateral is not in the possession of any third party bailee (such as a warehouse). Except as hereafter disclosed to the Lenders in writing by Borrower, none of the components of the Collateral shall be maintained at locations other than as provided in the Perfection Certificate. In the event that Borrower, after the date hereof, intends to store or otherwise deliver any portion of the Collateral to a bailee, then Borrower will first receive the written consent of Lenders and such bailee must acknowledge in writing that the bailee is holding such Collateral for the benefit of Lenders. All Inventory is in all material respects of good and marketable quality, free from material defects. Borrower is the sole owner of the Intellectual Property, except for non-exclusive licenses granted to its customers in the ordinary course of business. To Borrower’s knowledge, 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 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 cause a Material Adverse Change.

6

5.3                               Litigation.

Except as shown in the Perfection Certificate, there are no actions or proceedings pending or, to the knowledge of Borrower’s Responsible Officers, threatened by or against Borrower or any Subsidiary in which an adverse decision could reasonably be expected to cause a Material Adverse Change.

5.4                               No Material Deterioration in Financial Statements.

All consolidated financial statements for Borrower, and any Subsidiary, delivered to Lenders fairly present in all material respects Borrower’s consolidated financial condition and Borrower’s consolidated results of operations. There has not been any material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements submitted to Lenders.

5.5                               Solvency.

The fair salable value of Borrower’s assets (including goodwill minus disposition costs) exceeds the fair value of its liabilities; the Borrower is not left with unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as they mature.

5.6                               Regulatory Compliance.

Borrower is not an “investment company” or a company “controlled”  by an “investment company” under the Investment Company Act. 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. Borrower has not violated any laws, ordinances or rules, the violation of which could reasonably be expected to cause a Material Adverse Change. None of Borrower’s or any Subsidiary’s 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 and each Subsidiary has timely filed all required tax returns and paid, or made adequate provision to pay, all material taxes, except those being contested in good faith with adequate reserves under GAAP. Borrower and each Subsidiary has obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all government authorities that are necessary to continue its business as currently conducted, except where the failure to make such declarations, notices or filings would not reasonably be expected to cause a Material Adverse Change.

5.7                               Subsidiaries.

Borrower does not own any stock, partnership interest or other equity securities except for Permitted Investments.

5.8                               Full Disclosure.

No written representation, warranty or other statement of Borrower in any certificate or written statement given to any Lender (taken together with all such written certificates and written statements given to any 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 Lenders that the projections and forecasts provided by Borrower

7

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.

All property policies shall have a lender’s loss payable endorsement showing each Lender as an additional loss payee and waive subrogation against Lenders, and all liability policies shall show, or have endorsements showing, each Lender as an additional insured.

At Lenders’ request, Borrower shall deliver certified copies of policies and evidence of all premium payments. Proceeds payable under any policy shall, at Lenders’ option, be payable to Lenders on account of the Obligations. Notwithstanding the foregoing, (a) so long as no Event of Default has occurred and is continuing, Borrower shall have the option of applying the proceeds of any casualty policy toward the replacement or repair of destroyed or damaged property; provided that any such replaced or repaired property (i) shall be of equal or like value as the replaced or repaired Collateral and (ii) shall be deemed Collateral in which Lenders have been granted a first priority security interest, and (b) after the occurrence and during the continuance of an Event of Default, all proceeds payable under such casualty policy shall, at the option of Lenders, be payable to Lenders on account of the Obligations.

Borrower grants Lenders a license to enter and occupy any of its premises, without charge, to exercise any of Lenders’ rights or remedies;

9.4                               Lenders Expenses

Any amounts paid by Lenders as provided herein are Lenders Expenses and are immediately due and payable and shall bear interest at the then applicable rate and be secured by the Collateral.

Lenders’ rights and remedies under this Agreement, the Loan Documents, and all other agreements are cumulative. Lenders have all rights and remedies provided under the Code, by law, or in equity. Lenders’ exercise of one right or remedy is not an election, and Lenders’ waiver of any Event of Default is not a continuing waiver. Lenders’ delay is not a waiver, election, or acquiescence. No waiver hereunder shall be effective unless signed by each Lender 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 Lenders on which Borrower is liable.
