LOAN AND SECURITY AGREEMENT

1. Loans. Bank will make extensions of credit or other financial accommodations for Borrower’s benefit (each, a “Loan” and collectively, “Loans”), and Borrower promises to pay Bank the amount of all Loans and other debts, principal, interest, Bank Expenses (as defined in Section 8.2), the Prepayment Premium, the Final Payment, and other amounts Borrower owes Bank now or later and interest accruing after insolvency proceedings begin and debts, liabilities, or obligations of Borrower assigned to Bank (collectively, “Obligations”) pursuant to the terms and conditions of this Agreement or the other Loan Documents, and as set forth on Schedule A. Bank’s obligation to make any Loan is subject to its receipt of the agreements, documents and fees it reasonably requires.

2. Security Interest. As security for all present and future Obligations and for Borrower’s performance for each of its duties hereunder, Borrower grants Bank a continuing security interest in all of Borrower’s interest in the Collateral (as defined in Schedule B).

3. Representations, Warranties and Covenants of Borrower. Except as set forth under Item 12 of Schedule D attached hereto, Borrower represents, warrants and covenants to Bank as follows, as of the Effective Date and with respect to covenants, for so long as this Agreement is in effect or any Obligations remain outstanding:

3.1 Corporate Existence; Authority. Each of Borrower and its Subsidiaries is and will continue to be, 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 where such qualification is necessary, except for jurisdictions in which failure to do so would not have a material adverse effect on Borrower. The execution, delivery and performance by Borrower of this Agreement and all other related documents have been duly and validly authorized, do not conflict with Borrower’s formation documents, and do not constitute an event of default under any material agreement by which Borrower is bound. “Subsidiaries” means any entity of which more than 50% of the voting stock or other equity interests is owned or controlled, directly or indirectly, by Borrower.

63.2 Collateral. Bank has and will at all times continue to have a first-priority perfected security interest in all of the Collateral. Borrower has, and will continue to have, good title to the Collateral, free of any liens except Permitted Liens. Borrower will immediately advise Bank in writing of any material loss or damage to the Collateral.

3.3 Financial Matters. All financial statements (including notes and schedules) now or in the future delivered to Bank, (i) have presented, and will present, fairly in all material respects Borrower’s financial condition and its results of operations, and (ii) have been, and will be, prepared in conformity with generally accepted accounting principles (“GAAP”), except for the absence of footnotes and subject to year-end adjustments. Since the last date covered by any such statement, there has been no material impairment in the financial condition or business of Borrower. Borrower will provide Bank with all financial reports as set forth on Schedule A attached hereto, as well as any other financial information reasonably requested by Bank from time to time, including budgets, projections and plans.

3.4 Taxes; Legal Compliance. Borrower has filed, and will file, when due (including under any permitted extensions under applicable law), all tax returns and reports required by applicable law. Borrower has paid, and will pay when due, all taxes, assessments, deposits and contributions now or in the future owed (except for taxes and assessments being contested in good faith with adequate reserves under GAAP). Borrower has complied, and will comply, in all material respects, with all applicable laws, rules and regulations.

3.5 Insurance. Borrower shall at all times insure all of the tangible personal property Collateral and carry such other business insurance as is customary for companies similarly situated to Borrower. All property policies will have a lender’s loss payable endorsement showing Bank as a lender loss payee and provide that the insurer must give Bank at least twenty (20) days’ notice before canceling its policy.

3.6 Access. Upon one (1) Business Day’s prior notice, Bank or its agents shall have the right to inspect the Collateral and to audit and copy Borrower’s books and records during Borrower’s regular business hours. A “Business Day” is any day that is not a Saturday, Sunday or a day on which the Bank is closed. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing, Bank shall not be required to provide written notice to Borrower of any inspection or audit.

3.7 Banking Matters. Borrower shall at all times maintain its banking relationship with Bank in a manner as set forth on Schedule A.

3.8 Statement of Borrower’s Information. All of Borrower’s information set forth on Schedule D is true and correct as of the Effective Date, and Borrower shall provide written notice to Bank of any material changes within the prescribed periods of time set forth therein.

3.9 Insolvency. Borrower is able, and will continue to be able, to pay its debts (including trade debts) as they mature.

3.10 Additional Agreements. Borrower will not, and will not permit any of its Subsidiaries to, without Bank’s prior written consent (which shall be a matter of Bank’s good faith business judgment), do any of the following: (i) convey, sell, lease, transfer or otherwise dispose of (“Transfer”) any property other than Permitted Transfers; (ii) engage in any business other than the business currently engaged in by Borrower or reasonably related thereto; (iii) permit or suffer to exist a change in its ownership existing as of the Effective Date in excess of the Ownership Threshold, except for the sale of capital stock to venture or strategic investors, provided that Bank receives at least five (5) Business Days’ prior written notice of such sale and such sale does not otherwise result in an Event of Default (as defined in Section 5); (iv) merge or consolidate with any party, or acquire all or substantially all of the capital stock or assets of another party; (v) incur or become liable for any indebtedness other than Permitted Indebtedness; (vi) assign or convey any rights to income or incur or allow any lien, security interest or other encumbrance on any of its property other than Permitted Liens, or enter into any agreement, document, instrument or other arrangement (except with or in favor of Bank) with any Person which directly or indirectly prohibits or has the effect of prohibiting Borrower or any Subsidiary from assigning, mortgaging, pledging, granting a security interest in or upon, or encumbering any of Borrower’s or any Subsidiary’s Intellectual Property; (vii) make any investments except for Permitted Investments; (viii) pay or declare any dividends on Borrower’s stock; (ix) redeem, retire, purchase or otherwise acquire, directly or indirectly, any of Borrower’s stock other than stock repurchased in connection with the termination of employment or service as a consultant or director; (x) directly or indirectly enter into any material transaction with any affiliate except in the ordinary course of business upon reasonable terms no less favorable than those in an arm’s-length transaction with a non-affiliate (provided that the foregoing restriction shall not apply to reasonable and customary compensation arrangements with, and the award of equity for compensatory purposes to officers, employees and directors of Borrower in the ordinary course of business); or (xi) make any payment on, or materially change any term relating to, any indebtedness which is subordinated to any indebtedness owed to Bank by Borrower. Borrower shall not, without at least thirty (30) days’ prior written notice to Bank, relocate its principal offices from Borrower’s address set forth on the signature page hereof or change its state of formation. Borrower shall take or authorize any further actions (including Bank’s filing of financing statements to perfect Bank’s security interest in the Collateral) and execute any further instruments as Bank reasonably requests to perfect or continue Bank’s security interests or to effect the purposes of this Agreement.

3.11 Full Disclosure. No written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank, in the aggregate, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statement contained in such certificates or statements not misleading.

4. Term. This Agreement shall continue in effect until the maturity date set forth on Schedule A (the “Maturity Date”). On the Maturity Date or on any earlier effective date of termination of this Agreement, Borrower shall pay in cash all Obligations in full, whether or not such Obligations are otherwise then due and payable. No termination shall in any way affect or impair any security interest or other right or remedy of Bank, nor shall any such termination relieve Borrower of any obligation to Bank, until all of the Obligations have been paid and performed in full.

5. Events of Default. The occurrence of any of the following events shall constitute an “Event of Default” hereunder: (i) Borrower fails to deliver the financial statements and other information pursuant to Section 3.3 above within the prescribed period of time; (ii) Borrower fails to pay when due any Loan or other monetary Obligation within three (3) Business Days after the due date (during which time no additional Loans shall be made by Bank); (iii) Borrower fails to perform any obligation (other than payment of any Loan or other Obligations or those pursuant to Section 3.3 above) or covenant hereunder, which, if such default can be reasonably cured, is not cured within ten (10) days after the date due (or a later date, as approved in writing by Bank); (iv) a Material Adverse Change; (v) any representation, or written statement given to Bank by or on behalf of Borrower, now or in the future, is untrue or misleading in a material respect; (vi) a default in any agreement between Borrower and a third party that gives the third party the right to accelerate any indebtedness exceeding the Contract Threshold Amount or that could reasonably be expected to cause any material impairment in the Borrower’s business, operations or financial or other condition of the Borrower; (vii) the attachment, seizure, levy or possession by a trustee or receiver of any material portion of Borrower’s assets which is not removed within ten (10) days from its occurrence; (viii) the enjoinment, restraint or prevention by court order from conducting a material part of Borrower’s business, which is not terminated within ten (10) days of its occurrence; (ix) the dissolution, winding up, or insolvency of Borrower; or (x) the appointment of a receiver, trustee or custodian, for all or part of the property of, assignment for the benefit of creditors by, or commencement of any proceeding by or against, Borrower under any reorganization, bankruptcy, insolvency, arrangement, readjustment of debt, dissolution or liquidation law or statute of any jurisdiction, now or in the future in effect.

6. Rights and Remedies. If an Event of Default occurs and continues, Bank may, without notice or demand do any or all of the following: (i) accelerate and declare all of the Loans and other Obligations to be immediately due and payable (but if an Event of Default described in Sections 5(ix) or 5(x) occurs, all Obligations are immediately due and payable without any action by Bank); (ii) stop advancing money or extending credit for Borrower’s benefit under this Agreement or any other agreement between Borrower and Bank; (iii) make any payments and do any acts it considers necessary or reasonable to protect its security interest in the Collateral (and Borrower will reasonably cooperate with Bank accordingly); (iv) apply to the Obligations any balances and deposits of Borrower that Bank holds or any amount held by Bank owing to or for the credit or the account of Borrower; (v) increase the then-existing

interest rate by an additional five percent (5.0%) per annum; (vi) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale and sell or otherwise dispose of the Collateral; and/or (vii) exercise any other rights and remedies permitted by applicable law. Effective only when an Event of Default occurs and continues, Borrower irrevocably appoints Bank as its lawful attorney to: (a) make, settle, and adjust all claims under Borrower’s insurance policies; and (b) transfer the Collateral into the name of Bank or a third party as the Massachusetts Uniform Commercial 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. All of Bank’s rights and remedies under this Agreement or any other agreement between Bank and Borrower are cumulative. 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.

7. Indemnification. Borrower will indemnify, defend and hold harmless Bank and its affiliates, and each of their officers, directors, employees, attorneys, accountants and agents against: (i) all obligations, demands, claims, and liabilities asserted by any other party in connection with the transactions contemplated hereunder; and (ii) all losses and expenses incurred, or paid by Bank arising from transactions between Bank and Borrower contemplated by the Loan Documents (including reasonable attorneys’ fees and expenses), except, as to both “(i)” and “(ii)” in this Section 7, for losses caused by Bank’s gross negligence or willful misconduct. This Section 7 shall survive termination of this Agreement.

8. General.

8.1 No Waivers; Amendments. The failure of Bank at any time to require Borrower to comply strictly with any of the provisions of this Agreement shall not waive Bank’s right to later demand and receive strict compliance. Any waiver of a default shall not waive any other default. None of the provisions of this Agreement may be waived except by a specific written waiver signed by Bank and delivered to Borrower. The provisions of this Agreement may not be amended except in a writing signed by Borrower and Bank.

8.2 Bank Expenses; Attorneys’ Fees. Borrower shall reimburse Bank for all audit fees and expenses and reasonable costs and expenses (including reasonable attorneys’ fees and expenses) for preparing, negotiating, administering, defending and enforcing this Agreement and the other Loan Documents with Bank (including appeals or insolvency proceedings) (collectively, “Bank Expenses”). If, subject to the foregoing, Bank or Borrower files any lawsuit against the other predicated on a breach of this Agreement, the prevailing party shall be entitled to recover its costs and reasonable attorneys’ fees from the non-prevailing party.

8.3 Binding Effect; Assignment. This Agreement is binding upon and for the benefit of the successors and permitted assignees of each party. Borrower may not assign any rights under this Agreement without Bank’s prior written consent. Bank has the right, without the consent of or notice to Borrower, to sell transfer, assign, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights, and benefits under this Agreement and the other Loan Documents.

8.4 Notices. All notices by any party required or permitted under this Agreement or any other related agreement must be in writing and be personally delivered or sent by overnight delivery, certified mail (postage prepaid and return receipt requested), or facsimile to the addresses and numbers below.

8.5 Governing Law; Jurisdiction. This Agreement shall be governed by the laws of the Commonwealth of Massachusetts without regard to principles of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction of the federal and state courts in Boston, Massachusetts; provided that if for any reason Bank cannot avail itself of such courts in the Commonwealth of Massachusetts, Borrower accepts jurisdiction of the courts and venue in Santa Clara County, California.

8.6 Other. If any provision hereof is unenforceable, the remainder of this Agreement shall continue in full force and effect. This Agreement (including schedules hereto) and any other written agreements and, documents executed in connection herewith are the complete agreement between Borrower and Bank and supersede all prior and contemporaneous negotiations and oral representations and agreements, all of which are merged and integrated herein. This Agreement may be executed in one or more counterparts, all of which when taken together will constitute one agreement.

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

10. Mutual Waiver of Jury Trial. BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF THIS AGREEMENT OR ANY RELATED DOCUMENT OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY, 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.

11. Right of Set Off. Borrower hereby grants to Bank, a lien, security interest and right of set off as security for all Obligations to Bank, whether now existing or hereafter arising upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of Bank or any entity under the control of Bank (including a Bank subsidiary) or in transit to any of them. At any time after the occurrence and during the continuance of an Event of Default, without demand or notice, Bank may set off the same or any part thereof and apply the same to any liability or obligation of Borrower even though unmatured and regardless of the adequacy of any other collateral securing the Obligations. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF BORROWER ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

[Signature page follows.]

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed as a sealed instrument under the laws of the Commonwealth of Massachusetts as of the date initially set forth above.
