ARTICLE 2 THE LOAN

2.1 Advances. Subject to the terms and conditions of this Agreement, within two days after the Closing Date, Lender shall fund an initial Advance in the principal amount of $6,000,000 (“Tranche A”). Beginning September 15, 2007, and continuing through December 31, 2007, Borrower may request additional Advances in an aggregate amount of up to $4,000,000 (“Tranche B”).

2.2 Advance Request. To obtain an Advance, Borrower shall complete, sign and deliver an Advance Request and Note to Lender. Lender shall fund the Advance no later than 12:00 p.m. (California time) on the next Business Day following the date the Advance Request is delivered by the Borrower in the manner requested by the Advance Request, provided that each of the conditions precedent to such Advance is satisfied as of the date of the Advance Request.

2.3 Interest. The principal balance of each Advance shall bear interest thereon from the Advance Date at the Interest Rate based on a year consisting of 360 days, with interest computed daily based on the actual number of days elapsed (including the first day, but excluding the last day). The Interest Rate for each Advance will be fixed on the date of that Advance, and will apply to that Advance for so long as it is outstanding, including during the period of amortization.

2.4 Payment. Borrower will pay accrued interest in arrears on each Advance on the last Business Day of each month, beginning with the first month after the Advance Date. Borrower shall repay the aggregate principal amount of the Loans that are outstanding on May 16, 2008 in thirty (30) equal monthly installments of principal and interest beginning on the last Business Day of June, 2008, provided however, that if Borrower completes any two Milestones on or prior to the first anniversary of the Closing Date, then Borrower shall repay the aggregate principal amount of the Loans that is outstanding on May 16, 2008 in 33 equal monthly installments of principal and interest beginning on the last Business Day of June 2008 and continuing on the last Business Day of each month thereafter.

Borrower shall make all payments under this Agreement without setoff, recoupment or deduction and regardless of any counterclaim or defense.

2.5 Maximum Interest. Notwithstanding any provision in this Agreement, the Notes, or any other Loan Document, it is the parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that a court of competent jurisdiction shall deem applicable hereto (which under the laws of the State of California shall be deemed to be the laws relating to permissible rates of interest on commercial loans) (the “Maximum Rate”). If a court of competent jurisdiction shall finally determine that Borrower has actually paid to Lender an amount of interest in excess of the amount that would have been payable if all of the Secured Obligations had at all times borne interest at the Maximum Rate, then such excess interest actually paid by Borrower shall be applied as follows: first, to the payment of principal outstanding on the Notes; second, after all principal is repaid, to the payment of Lender’s accrued interest, costs, expenses, professional fees and any other Secured Obligations; and third, after all Secured Obligations are repaid, the excess (if any) shall be refunded to Borrower.

2.6 Default Interest. In the event any payment required under Section 2.4 (but not under Section 2.7) is not paid on the scheduled Payment Date, a one-time penalty in an amount equal to five percent (5%) of the past due amount shall be payable by Borrower on demand. In addition, upon the occurrence and during the continuation of an Event of Default hereunder, all Secured Obligations to the extent then due and owing (including principal, interest, and professional fees) shall during such period bear interest at a rate per annum equal to the rate set forth in Section 2.2 plus five percent (5%) per annum.

2.7 Prepayment and Termination of Commitments. Upon at least 5 business days prior written notice, Borrower may prepay all or any part of the Advances by paying the outstanding principal amount and all accrued but unpaid interest and fees, plus a prepayment premium equal to (i) 2.5% of the principal prepaid if paid on or before June 16, 2008, and (ii) 1.5% of the principal prepaid if paid anytime after June 16, 2008 but before the Maturity Date. Once repaid, Borrower may not reborrow any Advances. Each notice of a prepayment pursuant to this Section 2.7 shall be irrevocable, provided that a notice may be conditioned upon the effectiveness or closing of other credit facilities or debt or equity financings, in which case, such notice may be revoked by the Borrower by notice to the Lender if such condition is not satisfied. All Secured Obligations shall at Lender’s option become immediately due and payable upon the occurrence of a Prepayment Event. The Borrower shall have the right at any time to terminate the Lender’s obligation to fund the Advances by giving the Lender written notice of such election to terminate. Such termination shall be effective upon receipt of such notice by the Lender.

2.8 End of Term Charge. On the earliest to occur of (i) the Maturity Date, (ii) the date that Borrower prepays the outstanding Advances, or (iii) the Secured Obligations become due and payable, Borrower shall pay Lender a charge of three percent (3.0%) of all Advances drawn by Borrower hereunder.

No omission or delay by Lender at any time to enforce any right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by Borrower at any time designated, shall be a waiver of any such right or remedy to which Lender is entitled, nor shall it in any way affect the right of Lender to enforce such provisions thereafter.

11.6 Survival. All agreements, representations and warranties contained in this Agreement, the Notes and the other Loan Documents or in any document delivered pursuant hereto or thereto shall be for the benefit of Lender and shall survive the execution and delivery of this Agreement and the expiration or other termination of this Agreement.

Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either party to bring proceedings in the courts of any other jurisdiction.

11.10 Mutual Waiver of Jury Trial / Judicial Reference.

(a) Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an experienced and expert person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF BORROWER AND LENDER SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY BORROWER AGAINST LENDER OR ITS ASSIGNEE OR BY LENDER OR ITS ASSIGNEE AGAINST BORROWER. This waiver extends to all such Claims, including Claims that involve Persons other than Borrower and Lender; Claims that arise out of or are in any way connected to the relationship between Borrower and Lender; and any Claims for damages, breach of contract, tort, specific performance, or any equitable or legal relief of any kind, arising out of this Agreement, any other Loan Document.

(b) If the waiver of jury trial set forth in Section 11.10(a) is ineffective or unenforceable, the parties agree that all Claims shall be resolved by reference to a private judge sitting without a jury, pursuant to Code of Civil Procedure Section 638, before a mutually acceptable referee or, if the parties cannot agree, a referee selected by the Presiding Judge of the Santa Clara County, California. Such proceeding shall be conducted in Santa Clara County, California, with California rules of evidence and discovery applicable to such proceeding.

(c) In the event Claims are to be resolved by judicial reference, either party may seek from a court identified in Section 11.10, any prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to resolution by judicial reference.

11.11 Professional Fees. Borrower promises to pay Lender’s fees and expenses necessary to finalize the loan documentation, including but not limited to reasonable attorneys fees, UCC searches, filing costs, and other miscellaneous expenses upon presentation of reasonable documentation or invoices; provided, however, that the Commitment Fee shall be credited against the Lender’s non-legal transaction costs and due diligence expenses. In addition, Borrower promises to pay any and all reasonable attorneys’ and other professionals’ fees and expenses incurred by Lender after the Closing Date in connection with or related to: (a) the collection or enforcement of the Loan; (b) the amendment or modification of the Loan Documents (to the extent such amendment or modification is requested by the Borrower); (c) any waiver, consent, release, or termination under the Loan Documents; (d) the protection, preservation, sale, lease, liquidation, or disposition of Collateral or the exercise of remedies with respect to the Collateral; (e) any legal, litigation, administrative, arbitration, or out of court proceeding in connection with or related to Borrower or the Collateral, and any appeal or review thereof; and (f) any bankruptcy, restructuring, reorganization, assignment for the benefit of creditors, workout, foreclosure, or other action related to Borrower, the Collateral, the Loan Documents, including representing Lender in any adversary proceeding or contested matter commenced or continued by or on behalf of Borrower’s estate, and any appeal or review thereof.

11.12 Confidentiality. Lender acknowledges that certain items of Collateral, Intellectual Property of the Borrower and information provided to Lender by Borrower are confidential and proprietary information of Borrower, (the “Confidential Information”). Accordingly, Lender agrees that any Confidential Information it may obtain in the course of acquiring, administering, or perfecting Lender’s security interest in the Collateral shall not be disclosed to any other person or entity in any manner whatsoever, in whole or in part, without the prior written consent of Borrower, except that Lender may disclose any such information: (a) to its own directors, officers, employees, accountants, counsel and other professional advisors and to its Affiliates if Lender in its sole discretion determines that any such party should have access to such information in connection with such party’s responsibilities in connection with the Loan or this Agreement and, provided that such recipient of such Confidential Information either (i) agrees to be bound by the confidentiality provisions of this paragraph or (ii) is otherwise subject to confidentiality restrictions that reasonably protect against the disclosure of Confidential Information; (b) if such information is generally available to the public; (c) if required in any report, statement or testimony submitted to any governmental authority having jurisdiction over Lender; (d) in response to any summons or subpoena or in connection with any litigation, to the extent Lender’s counsel advises that such disclosure is legally required; (e) to comply with any legal requirement or law applicable to Lender; (f) to the extent reasonably necessary in connection with the exercise of any right or remedy under any Loan Document, including Lender’s sale, lease, or other disposition of Collateral after default; (g) to any participant or assignee of Lender or any prospective participant or assignee; provided, that such participant or assignee or prospective participant or assignee agrees in writing to be bound by this Section prior to disclosure; or (h) otherwise with the prior consent of Borrower; provided, that any disclosure made in violation of this Agreement shall not affect the obligations of Borrower or any of its Affiliates or any guarantor under this Agreement or the other Loan Documents.

11.13 Assignment of Rights. Lender may sell and assign all or part of its interest hereunder and under the Note(s) and Loan Documents (a) to any Affiliate of Lender servicing the Loan in connection with the Note Purchase Agreement among Hercules Funding Trust I, Hercules Funding I LLC, Hercules Technology Growth Capital, Inc. and Citigroup Global Markets Realty Corp., dated as of August 1, 2005, (b) to any Affiliate of Lender licensed by the U.S. Small Business Administration, (c) as collateral security to Lender’s senior secured lender to the extent required under the applicable loan agreement, and (d) in connection with any securitization undertaken by Lender and/or its Affiliates, provided that Lender or an Affiliate of Lender continues to service the Loan (each of (a), (b), (c) and (d), being a “Permitted Assignee”), . After such assignment, the term “Lender” as used in the Loan Documents shall mean and include such Permitted Assignee, and such Permitted Assignee shall be vested with all rights, powers and remedies of Lender hereunder with respect to the interest so assigned; but with respect to any such interest not so transferred, Lender shall retain all rights, powers and remedies hereby given. No such assignment by Lender shall relieve Borrower of any of its obligations hereunder. Lender agrees that in the event of any transfer by it of the Note(s), it will endorse thereon a notation as to the portion of the principal of the Note(s), which shall have been paid at the time of such transfer and as to the date to which interest shall have been last paid thereon. Other than to a Permitted Assignee, no sale or assignment by Lender of all or any part of the Note(s) or Loan Documents shall be permitted under this Agreement without the prior written consent of Borrower, provided that after the occurrence and during the continuation of an Event of Default, Lender may sell or assign all or any part of its interest hereunder and under the Note(s) and Loan Documents to any Person without the consent of Borrower.

11.14 Revival of Secured Obligations. This Agreement and the Loan Documents shall remain in full force and effect and continue to be effective if any petition is filed by or against Borrower for liquidation or reorganization, if Borrower becomes insolvent or makes an assignment for the benefit of creditors, if a receiver or trustee is appointed for all or any significant part of Borrower’s assets, or if any payment or transfer of Collateral is recovered from Lender. The Loan Documents and the Secured Obligations and Collateral security shall continue to be effective, or shall be revived or reinstated, as the case may be, if at any time payment and performance of the Secured Obligations or any transfer of Collateral to Lender, or any part thereof is rescinded, avoided or avoidable, reduced in amount, or must otherwise be restored or returned by, or is recovered from, Lender or by any obligee of the Secured Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment, performance, or transfer of Collateral had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, avoided, avoidable, restored, returned, or recovered, the Loan Documents and the Secured Obligations shall be deemed, without any further action or documentation, to have been revived and reinstated except to the extent of the full, final, and indefeasible payment to Lender in Cash.

11.15 Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same instrument.

11.16 No Third Party Beneficiaries. No provisions of the Loan Documents are intended, nor will be interpreted, to provide or create any third-party beneficiary rights or any other rights of any kind in any person other than Lender and Borrower unless specifically provided otherwise herein, and, except as otherwise so provided, all provisions of the Loan Documents will be personal and solely between the Lender and the Borrower.

11.17 Specific Performance. The parties hereto hereby declare that it is impossible to measure in money the damages which will accrue to Lender by reason of Borrower’s failure to perform any of the obligations under this Agreement and agree that the terms of this Agreement shall be specifically enforceable by Lender. If Lender institutes any action or proceeding to specifically enforce the provisions hereof, any Person against whom such action or proceeding is brought hereby waives the claim or defense therein that Lender has an adequate remedy at law, and such Person shall not offer in any such action or proceeding the claim or defense that such remedy at law exists.

11.18 Publicity. Lender may use Borrower’s name and logo, and include a brief description of the relationship between Borrower and Lender, in Lender’s marketing materials in a form to be mutually agreed by Lender and Borrower.

11.19 Termination and Release. When all the non-contingent Secured Obligations have been paid in full and have been terminated and the obligation of the Lender to make any Advances hereunder has terminated or expired, this Agreement and the first priority security interest in the Collateral created hereby shall terminate and all rights to the Collateral shall automatically revert to the Borrower, all without delivery of any instrument or performance of any act by any party. If any of the Collateral shall be sold, transferred or otherwise disposed of by the Borrower in a transaction permitted hereby or in a transaction with respect to which any written consent to the release of any Lien created hereunder in respect of any Collateral has been obtained, the Lien created pursuant to this Agreement on such Collateral shall be automatically released, all without delivery of any instrument or performance of any act by any party. In connection with any release or termination referred to in this Section 11.19, the Lender agrees to execute appropriate releases of liens on the Collateral upon the request of the Borrower and at the Borrower’s expense.
