(c) Purchaser understands that the Securities have not been registered. Purchaser understands that the Securities will not be registered under the Act on the ground that the issuance thereof is exempt under Section 4(2) of the Act as a transaction by an issuer not involving any public offering and that, in the view of the United States Securities and Exchange Commission (the “SEC”), the statutory basis for the exception claimed would not be present if any of the representations and warranties of Purchaser contained in this Agreement or those of other purchasers of the Securities are untrue or, notwithstanding Purchaser’s representations and warranties, Purchaser currently has in mind acquiring any of the Securities for resale upon the occurrence or non-occurrence of some predetermined event.

4

(d) Purchaser is purchasing the Securities for investment purposes and not with a view to distribution or resale, nor with the intention of selling, transferring or otherwise disposing of all or any part thereof for any particular price, or at any particular time, or upon the happening of any particular event or circumstance, except selling, transferring, or disposing the Securities in full compliance with all applicable provisions of the Act, the rules and regulations promulgated by the SEC thereunder, and applicable state securities laws; and that an investment in the Securities is not a liquid investment.

(e) Purchaser acknowledges that it has had the opportunity to ask questions of, and receive answers from, the Company or any authorized person acting on its behalf concerning the Company and its business and to obtain any additional information, to the extent possessed by the Company (or to the extent it could have been acquired by the Company without unreasonable effort or expense) necessary to verify the accuracy of the information received by Purchaser. In connection therewith, Purchaser acknowledges that it has had the opportunity to discuss the Company’s business, management and financial affairs with the Company’s management or any authorized person acting on its behalf. Purchaser has received and reviewed all the information concerning the Company and the Securities, both written and oral, that Purchaser desires with respect to the Company’s business, management, financial affairs and prospects, including without limitation, the Risk Factors set forth in Exhibit E. In determining whether to make this investment, Purchaser has relied solely on (i) Purchaser’s own knowledge and understanding of the Company and its business based upon Purchaser’s own due diligence investigations and the information furnished pursuant to this paragraph, and (ii) the information described in subparagraph 2(f) below.

(f) Purchaser has all requisite legal and other power and authority to execute and deliver this Agreement and to carry out and perform Purchaser’s obligations under the terms of this Agreement. This Agreement constitutes a valid and legally binding obligation of Purchaser, enforceable in accordance with its terms, subject to laws of general application relating to bankruptcy, insolvency and the relief of debtors and rules of law governing specific performance, injunctive relief or other general principles of equity, whether such enforcement is considered in a proceeding in equity or law.

(g) Purchaser has carefully considered and has discussed with Purchaser’s legal, tax, accounting and financial advisors, to the extent Purchaser has deemed necessary, the suitability of this investment and the transactions contemplated by this Agreement for Purchaser’s particular federal, state, local and foreign tax and financial situation and has independently determined that this investment and the transactions contemplated by this Agreement are a suitable investment for Purchaser. Purchaser has relied solely on such advisors and not on any statements or representations of the Company or any of its agents. Purchaser understands that Purchaser (and not the Company) shall be responsible for Purchaser’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement.

(j) There are no actions, suits, proceedings or investigations pending against Purchaser or Purchaser’s assets before any court or governmental agency (nor, to Purchaser’s knowledge, is there any threat thereof) which would impair in any way Purchaser’s ability to enter into and fully perform Purchaser’s commitments and obligations under this Agreement or the transactions contemplated hereby.

(k) The execution, delivery and performance of and compliance with this Agreement and the issuance of the Securities to Purchaser will not result in any violation of, or conflict with, or constitute a default under, any of Purchaser’s articles of incorporation or by-laws, or equivalent limited liability company, trust or partnership documents, if applicable, or any agreement to which Purchaser is a party or by which it is bound, nor result in the creation of any mortgage, pledge, lien, encumbrance or charge against any of the assets or properties of Purchaser or the Securities purchased by Purchaser.

(l) Purchaser acknowledges that an investment in the Securities is speculative and involves a high degree of risk and that Purchaser can bear the economic risk of the purchase of the Securities, including a total loss of his/her/its investment.

(m) Purchaser recognizes that no federal, state or foreign agency has recommended or endorsed the purchase of the Securities.

(o) Purchaser understands that the Notes and the Special Bridge Warrants shall bear the following legend or one substantially similar thereto, which Purchaser has read and understands:

NEITHER THIS SECURITY NOR ANY SECURITY INTO WHICH IT MAY BE CONVERTED HAS BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR APPLICABLE STATE SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY SECURITY INTO WHICH IT MAY BE CONVERTED NOR ANY INTEREST OR PARTICIPATION HEREIN OR THEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF AT ANY TIME IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM REGISTRATION.

6

(p) Purchaser understands that the Notes are subordinated to the approximately $4.3 million of indebtedness outstanding under that certain Loan and Security Agreement, dated January 29, 2008, by and among the Company, Silicon Valley Bank, as agent, and the lenders named therein, as amended.

BY ACCEPTANCE OF THIS NOTE, THE HOLDER HEREOF AGREES TO BE BOUND BY THE SUBORDINATION PROVISIONS SET FORTH HEREIN.

(q) Because of the legal restrictions imposed on resale, Purchaser understands that the Company shall have the right to note stop-transfer instructions in its stock transfer records, and Purchaser has been informed of the Company’s intention to do so.

(i) Regulatory Permits. The Company and the Subsidiary possess all certificates, authorizations and permits issued by the appropriate federal, state, local or foreign regulatory authorities necessary to conduct their respective businesses as currently conducted, except where the failure to possess such permits could not reasonably be expected to result in a Material Adverse Effect (“Material Permits”), and neither the Company nor the Subsidiary has received any notice of proceedings relating to the revocation or modification of any Material Permit.

(k) Disclosure. All of the disclosure furnished by or on behalf of the Company to the Purchasers regarding the Company, its business and the transactions contemplated hereby is true and correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

(l) No Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 2, neither the Company, nor any of its affiliates, nor any person acting on its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of the Act which would require the registration of any such securities under the Act.

(m) No General Solicitation. Neither the Company nor any person acting on behalf of the Company has offered or sold any of the Securities by any form of general solicitation or general advertising. The Company has offered the Securities for sale only to the Purchasers and certain other “accredited investors” within the meaning of Rule 501 under the Act.

11

(n) Acknowledgment Regarding Purchasers’ Purchase of Securities. The Company acknowledges and agrees that each of the Purchasers is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated thereby. The Company further acknowledges that no Purchaser is acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated thereby and any advice given by any Purchaser or any of their respective representatives or agents in connection with the Transaction Documents and the transactions contemplated thereby is merely incidental to the Purchasers’ purchase of the Securities. The Company further represents to each Purchaser that the Company’s decision to enter into this Agreement has been based solely on the independent evaluation of the transactions contemplated hereby by the Company and its representatives.

(o) Labor Relations. No material labor dispute exists or, to the knowledge of the Company, is imminent with respect to any of the employees of the Company which could reasonably be expected to result in a Material Adverse Effect. None of the Company’s or the Subsidiary’s employees is a member of a union that relates to such employee’s relationship with the Company or such Subsidiary, and neither the Company nor the Subsidiary is a party to a collective bargaining agreement, and the Company and the Subsidiary believe that their relationships with their employees are good. No executive officer, to the knowledge of the Company, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant in favor of any third party, and the continued employment of each such executive officer does not subject the Company or the Subsidiary to any liability with respect to any of the foregoing matters. The Company and the Subsidiary are in compliance with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in compliance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(p) Compliance. Neither the Company nor the Subsidiary: (i) is in violation of any order of any court, arbitrator or governmental body or (ii) is or has been in violation of any statute, rule or regulation of any governmental authority, including without limitation all foreign, federal, state and local laws applicable to its business and all such laws that affect the environment, except in each case as could not have or reasonably be expected to result in a Material Adverse Effect.

(q) Title to Assets. The Company and the Subsidiary have good and marketable title in all personal property owned by them that is material to the business of the Company and the Subsidiary, in each case free and clear of all liens, except for liens as do not materially affect the value of such property and do not materially interfere with the use made and proposed to be made of such property by the Company and the Subsidiary and liens for the payment of federal, state, foreign or other taxes, the payment of which is neither delinquent nor subject to penalties. Any real property and facilities held under lease by the Company and the Subsidiary are held by them under valid, subsisting and enforceable leases with which the Company and the Subsidiary are in compliance.

12

(r) Intellectual Property. The Company and the Subsidiary own all right, title and interest in, or possesses adequate and enforceable rights to use, all patents, patent applications, trademarks, trade names, service marks, copyrights, rights, licenses, franchises, trade secrets, confidential information, processes, formulations, software and source and object codes necessary for the conduct of their businesses (collectively, the “Intangibles”). Neither the Company nor the Subsidiary have infringed upon the rights of others with respect to the Intangibles and neither the Company nor the Subsidiary have received notice that they have or may have infringed or are infringing upon the rights of others with respect to the Intangibles, or any notice of conflict with the asserted rights of others with respect to the Intangibles that could, individually or in the aggregate, have a Material Adverse Effect.

(s) Insurance. The Company and the Subsidiary are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company and the Subsidiary are engaged. Neither the Company nor the Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect.

(t) Transactions With Affiliates and Employees. None of the officers or directors of the Company and, to the knowledge of the Company, none of the employees of the Company is presently a party to any transaction with the Company or the Subsidiary (other than for services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an officer, director, trustee or partner, in each case in excess of $120,000 other than for: (i) payment of salary or consulting fees for services rendered, (ii) reimbursement for expenses incurred on behalf of the Company and (iii) other employee benefits, including stock option agreements under any stock option plan of the Company.

The Purchasers shall have no obligation with respect to any fees or with respect to any claims made by or on behalf of other persons for fees of a type contemplated in this Section that may be due in connection with the transactions contemplated by the Transaction Documents.

(v) Investment Company. The Company is not, and is not an affiliate of, and immediately after receipt of payment for the Securities, will not be or be an affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as amended. The Company shall conduct its business in a manner so that it will not become subject to the Investment Company Act of 1940, as amended.

13

(y) No Disagreements with Accountants and Lawyers. There are no disagreements of any kind presently existing, or reasonably anticipated by the Company to arise, between the Company and the accountants and lawyers formerly or presently employed by the Company which could affect the Company’s ability to perform any of its obligations under any of the Transaction Documents.

(z) Indebtedness. Schedule 3(z) sets forth as of the date hereof all outstanding secured and unsecured Indebtedness of the Company or the Subsidiary, or for which the Company or the Subsidiary has commitments. For the purposes of this Agreement, “Indebtedness” means (x) any liabilities for borrowed money or amounts owed in excess of $50,000 (other than trade accounts payable incurred in the ordinary course of business), (y) all guaranties, endorsements and other contingent obligations in respect of indebtedness of others, whether or not the same are or should be reflected in the Company’s balance sheet (or the notes thereto), except guaranties by endorsement of negotiable instruments for deposit or collection or similar transactions in the ordinary course of business; and (z) the present value of any lease payments in excess of $50,000 due under leases required to be capitalized in accordance with GAAP.

4. Indemnification. Subject to the provisions of this Section 4, the Company will indemnify and hold Purchaser and its directors, officers, shareholders, members, managers, partners, officers, employees, representatives and agents (and any other persons with a functionally equivalent role of a person holding such titles notwithstanding a lack of such title or any other title), each person who “controls” the Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners or employees (and any other persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against Purchaser in any capacity, or any of them or their respective affiliates, by any stockholder of the Company who is not an affiliate of Purchaser, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is pleaded with particularity as follows and based upon a breach of Purchaser’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings Purchaser may have with any such stockholder or any violations by Purchaser of state or federal securities laws or any conduct by Purchaser which constitutes fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents.

5. Lock-Up.

(a) For six (6) months subsequent to the consummation of the IPO (the “Lock-Up Period”), so long as all officers, directors and existing holders of equity or equity-linked securities of the Company are similarly locked up, Purchaser shall not, directly or indirectly, offer, sell, agree to sell, grant any option with respect to, pledge or otherwise dispose of the shares of Common Stock and warrants issuable upon conversion of the Note or exercise of the Special Bridge Warrant (the “Locked-Up Shares”).

15

(b) Notwithstanding the foregoing, Purchaser may sell: (i) 25% of the Locked-Up Shares if the Trading Price exceeds $7.00 for five consecutive Trading Days; (ii) 50% of the Locked-Up Shares if the Trading Price exceeds $7.50 for five consecutive Trading Days; (iii) 75% of the Locked-Up Shares if the Trading Price exceeds $8.00 for five consecutive Trading Days; and (iv) 100% of the Locked-Up Shares if the Trading Price exceeds $8.50 for five consecutive Trading Days. For purposes of this Agreement, “Trading Price” shall mean the closing sales price of the Common Stock as reported on a public market in the U.S and “Trading Day” means a day on which the principal public market for the Common Stock is open for trading.

(c) Purchaser hereby authorizes the Company during the Lock-Up Period, so long as all officers, directors and existing holders of equity or equity-linked securities of the Company are similarly locked up, to cause any transfer agent for the Common Stock to decline to transfer, and to note stop-transfer restrictions on the stock register and other records relating to, the Locked-Up Shares for which Purchaser is the record holder and, in the case of Locked-Up Shares for which the Purchaser is the beneficial but not the record holder, agrees during the Lock-Up Period to cause the record holder to cause the relevant transfer agent to decline to transfer, and to note stop-transfer restrictions on the stock register and other records relating to, its Locked-Up Shares.

(f) No provision of this Agreement may be waived, modified, supplemented or amended except in a written instrument signed, in the case of an amendment, by the Company and Purchasers holding at least a majority in interest of the Securities purchased hereunder or, in the case of a waiver, by the party against whom enforcement of any such waived provision is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

(g) This Agreement shall be enforced, governed and construed in all respects in accordance with the laws of the State of New York, as such laws are applied by the New York courts except with respect to the conflicts of law provisions thereof.

(h) Any legal suit, action or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby shall be instituted exclusively in New York Supreme Court, County of New York, or in the United States District Court for the Southern District of New York. The parties hereto hereby: (i) waive any objection which they may now have or hereafter have to the venue of any such suit, action or proceeding, and (ii) irrevocably consent to the jurisdiction of the New York Supreme Court, County of New York, and the United States District Court for the Southern District of New York in any such suit, action or proceeding. The parties further agree to accept and acknowledge service of any and all process which may be

17

served in any such suit, action or proceeding in the New York Supreme Court, County of New York, or in the United States District Court for the Southern District of New York. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law.

(i) If any provision of this Agreement is held to be invalid or unenforceable under any applicable statute or rule of law, then such provision shall be deemed modified to conform with such statute or rule of law. Any provision hereof that may prove invalid or unenforceable under any law shall not affect the validity or enforceability of any other provisions hereof.

(j) The parties understand and agree that money damages would not be a sufficient remedy for any breach of this Agreement by the Company or the Purchaser and that the party against which such breach is committed shall be entitled to equitable relief, including an injunction and specific performance, as a remedy for any such breach, without the necessity of establishing irreparable harm or posting a bond therefor. Such remedies shall not be deemed to be the exclusive remedies for a breach by either party of this Agreement but shall be in addition to all other remedies available at law or equity to the party against which such breach is committed.

(k) All pronouns and any variations thereof used herein shall be deemed to refer to the masculine, feminine, singular or plural, as identity of the person or persons may require.

(l) This Agreement may be executed in counterparts and by facsimile, each of which shall be deemed an original, but all of which shall constitute one and the same instrument.
