SECTION 3

REPRESENTATIONS AND WARRANTIES OF INVESTORS

Each Investor hereby represents and warrants to the Company that, as of the date of the Initial Closing, and each Subsequent Closing at which such Investor participates:

3.1 Purchase for Own Account. Such Investor represents that it is acquiring the Notes, the Warrants and the Common Stock issuable upon exercise of the Warrants (collectively, the “Securities”) solely for investment for such Investor’s own account not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that such Investor has no present intention of selling, granting any participation in, or otherwise distributing the same. The acquisition by such Investor of any of the Securities shall constitute confirmation of the representation by such Investor that such Investor does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Securities.

3.2 Investment Experience. Either (i) such Investor or its officers, directors, managers or controlling persons has a preexisting personal or business relationship with the Company or its officers, directors or controlling persons, or (ii) such Investor, by reason of its own business and financial experience, has the capacity to protect its own interests in connection with the investment contemplated hereby. Such Investor represents that it is an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Securities. Such Investor acknowledges that any investment in the Securities involves a high degree of risk, and represents that it is able, without materially impairing its financial condition, to hold the Securities for an indefinite period of time and to suffer a complete loss of its investment.

3.3 Accredited Investor. Such Investor represents that it is an “accredited investor” within the meaning of Securities and Exchange Commission (“SEC”) Rule 501 of Regulation D, as presently in effect and, for the purpose of Section 25102(f) of the California Corporations Code, it is excluded from the count of “purchasers” pursuant to Rule 260.102.13 thereunder.

3.4 Restrictions on Transfer. Such Investor understands that the Securities are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Securities Act of 1933, as amended (the “Act”), only in certain limited circumstances. In this connection, such Investor represents that it is familiar with SEC Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Act. SUCH INVESTOR UNDERSTANDS AND ACKNOWLEDGES HEREIN THAT AN INVESTMENT IN THE COMPANY’S SECURITIES INVOLVES AN EXTREMELY HIGH DEGREE OF RISK AND MAY RESULT IN A COMPLETE LOSS OF HIS, HER OR ITS INVESTMENT. Such Investor understands that the Securities have not been and will not be registered under

the Act (other than as set forth in the Registration Rights Agreement) and have not been and will not be registered or qualified in any state in which they are offered, and thus the Investor will not be able to resell or otherwise transfer his, her or its Securities unless they are registered under the Act and registered or qualified under applicable state securities laws, or an exemption from such registration or qualification is available. Such Investor has no immediate need for liquidity in connection with this investment and does not anticipate that it will need to sell his, her or its Securities in the foreseeable future.

3.5 Further Limitations on Disposition. Without in any way limiting the representations set forth above, such Investor further agrees not to make any disposition of all or any portion of the Securities (other than the shares of Common Stock issuable on exercise of the Warrants, during such time as a registration statement under the Act covering such shares is in effect) unless and until the transferee has agreed in writing for the benefit of the Company to be bound by this Section 3 and (i) such Investor shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and (ii) if requested by the Company, such Investor shall have furnished the Company with an opinion of counsel reasonably satisfactory to the Company that such disposition will not require registration of such Securities under the Act. Notwithstanding the foregoing provision, no such registration statement or opinion of counsel shall be necessary for a transfer by such Investor that is a partnership or limited liability company to a partner of such partnership or a member of such limited liability company or a retired partner of such partnership who retires after the date hereof or a retired member of such limited liability company who retires after the date hereof, or to the estate of any such partner, retired partner, member or retired member or the transfer by gift, will or intestate succession by any partner or member to his or her spouse or to the siblings, lineal descendants or ancestors of such partner or member or his or her spouse, if the transferee agrees in writing to be subject to the terms hereof to the same extent as if he or she were an original Investor hereunder.

3.6 Legends. The Investor understands that the Securities, and any securities issued in respect thereof or exchange therefor, may bear one or all of the following legends:

(a) “THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.”

(b) Any legend required by the Blue Sky laws of any state to the extent such laws are applicable to the shares represented by the certificate so legended.

SECTION 4

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

The Company hereby represents and warrants to each Investor that, as of the date of the Initial Closing and each Subsequent Closing and other than as disclosed in the Company’s public filings:

4.1 Organization, Good Standing and Qualification; Licenses. The Company is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization and has all requisite power and authority, and holds all governmental licenses, permits, registrations and other approvals required under applicable law, to own and hold under lease its property and to carry on its business as now conducted and as proposed to be conducted, except where the failure to hold any such licenses, permits, registrations and other approvals could not result in a Material Adverse Effect. The Company is qualified to do business in each jurisdiction where the nature of its properties of the conduct of its business requires it to be so qualified to do business and where the failure so to qualify could result in a Material Adverse Effect.

4.2 Authorization. All action on the part of the Company necessary for the authorization, execution and delivery of this Agreement, the performance of all obligations of the Company hereunder, and the authorization, issuance (or reservation for issuance), sale and delivery of the Notes, the Warrants, and the shares of Common Stock underlying the Warrants, has been taken or will be taken prior to each Closing. The Company covenants and agrees that all shares of Common Stock which may be issued upon the exercise of the rights represented by the Warrants will, upon issuance, be duly authorized, validly issued, fully paid and nonassessable and free from all preemptive rights of any stockholder and free of all taxes, liens and charges with respect to the issue thereof. The Company has reserved a sufficient number of shares of authorized but unissued shares of Common Stock to provide for the exercise of the rights represented by the Warrants (assuming full vesting thereof). Each of the Transaction Documents to which the Company is a party constitutes the valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, and (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

4.3 Litigation. There is no action, suit, proceeding or investigation pending or, to the Company’s knowledge, currently threatened against the Company that questions the validity of this Agreement, the right of the Company to enter into this Agreement, or to consummate the transactions contemplated hereby, or that could reasonably be expected to result, either individually or in the aggregate, in any Material Adverse Effect, nor is the Company aware that there is any basis for the foregoing. The Company is not a party or subject to the provisions of any order, writ, injunction, judgment or decree of any court or Governmental Authority. There is no action, suit, proceeding or investigation by the Company currently pending or that the Company intends to initiate.

4.4 Absence of Required Consents; No Violations. No consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any Governmental Authority on the part of the Company is required in connection with the consummation of the transactions contemplated by the Transaction Documents, except for such filing(s) pursuant to applicable state securities laws as may be necessary, which filings will be timely effected after the relevant Closing, and except for recordings or filings in connection with the perfection of the Liens on the Collateral in favor of the Investors (or any Collateral Agent on their behalf). The Company is not in violation or default (i) of any provision of its Certificate of Incorporation and Bylaws, or (ii) in any material respect of any instrument, judgment, order, writ, decree or contract to which it is a party or by which it is bound, or, to the best of its knowledge, of any provision of any federal or state statute, rule or regulation which is, to the best of the Company’s knowledge, applicable to the Company (including the Employee Retirement Income Security Act of 1974, as amended, and any Environmental Laws). The execution, delivery and performance of the Transaction Documents and the consummation of the transactions contemplated thereby will not result in any such violation or be in conflict with or constitute, with or without the passage of time and giving of notice, either a default under any such provision, instrument, judgment, order, writ, decree or contract or an event that results in the creation of any Lien upon any material assets of the Company or the suspension, revocation, impairment, forfeiture or nonrenewal of any material permit, license, authorization or approval applicable to the Company, its business or operations or any of its assets or properties. As used herein, “Environmental Laws” means all applicable federal, state and local laws, rules, regulations, codes, ordinances, and the common law governing, regulating or otherwise affecting the environment or occupational health and safety relating to exposures to Hazardous Materials, including the federal Clean Air Act, the federal Clean Water Act, the federal Resource Conservation and Recovery Act, the federal Comprehensive Environmental Response, Compensation and Liability Act, the federal Toxic Substances Control Act and their state and local counterparts. The term “Hazardous Materials” means the existence in any form of polychlorinated biphenyls, friable asbestos, urea formaldehyde foam insulation, oil, gasoline, petroleum, petroleum products and petroleum-derived substances (other than in vehicles operated in the ordinary course of business), pesticides and herbicides, and any other chemical, material or substance deemed hazardous, toxic, corrosive, reactive, ignitable, radioactive, or flammable under any Environmental Laws.

4.5 Transaction Documents. All representations and warranties of the Company contained in the other Transaction Documents are true and correct in all material respects (except for representations or warranties already qualified by materiality, which are true and correct in all respects).

4.6 Insurance. All policies of insurance in effect of any kind or nature owned by or issued to the Company, including policies of life, fire, theft, product liability, public liability, property damage, other casualty, employee fidelity, workers’ compensation, property and liability insurance, (a) are, together with all policies of employee health and welfare and title insurance, if any, in full force and effect, (b) comply in all respects with the applicable requirements set forth herein and (c) are of a nature and provide such coverage, including through self-insurance, retentions and deductibles, as is customarily carried by companies engaged in similar businesses and owning similar properties in the same general areas in which the Company operates.

4.7 Permits. The Company has all franchises, permits, licenses, and any similar authority necessary for the conduct of its business as now conducted and as presently proposed to be conducted, the lack of which could materially and adversely affect the business, properties, prospects, or financial condition of the Company. The Company is not in default in any material respect under any of such franchises, permits, licenses, or other similar authority.

4.8 Intellectual Property. The Company has all intellectual property necessary for the conduct of its business as now conducted and as presently proposed to be conducted, the lack of which could materially and adversely affect the business, properties, prospects, or financial condition of the Company. None of such intellectual property infringes on the rights of any other person. The Company does not own any registered copyrights or registered trademarks. A complete list of the Company’s United States patents and applications for United States patents is set forth on Schedule A of the Patent Security Agreement.

4.9 Subsidiaries. The Company has no subsidiaries (direct or indirect) other than as set forth in Exhibit 21.1 to its Annual Report on Form 10-K filed on March 27, 2009. Each direct or indirect subsidiary of the Company (a) is not actively engaged in any business and (b) holds no material assets.

4.10 Financial Statements. The Company has delivered to the Investors its unaudited balance sheet, income statement and statement of stockholders’ equity at and for the three and nine months ended September 30, 2009 (collectively, the “Financial Statements”). The Financial Statements fairly present the financial condition and operating results of the Company as of the dates, and for the periods, indicated therein, subject to normal year-end audit adjustments. Except as set forth in the Financial Statements, and liabilities arising from the reduction of the Company’s workforce pursuant to the plan adopted by the Company’s board of directors on March 26, 2010, the Company has no material liabilities (contingent or otherwise) other than (i) liabilities incurred in the ordinary course of business subsequent to September 30, 2009, and (ii) obligations under contracts and commitments incurred in the ordinary course of business and not required under generally accepted accounting principles to be reflected in the Financial Statements, which, in both cases, individually or in the aggregate, are not material to the financial condition or operating results of the Company.

4.11 No Material Adverse Effect. Since the date of the Financial Statements, other than as publicly disclosed by the Company in filings with the SEC, the reduction of the Company’s workforce pursuant to the plan adopted by the Company’s board of directors on March 26, 2010 and the failure of the Company to be able to repay existing indebtedness to the Investors when due, no event has occurred or condition exists with respect to the Company or any other Person that has resulted in, or could reasonably be expected to result in, a Material Adverse Effect.

4.12 Disclosure. None of the representations or warranties made by the Company herein as of the date of such representations and warranties, and none of the statements contained in any other information with respect to the Company and its properties and assets, including each exhibit or report, furnished by or on behalf of the Company to the Investors in connection herewith, contains any untrue statement of a material fact or omits any material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances under which they are made, not misleading.

4.13 Offering. Subject in part to the truth and accuracy of each Investor’s representations set forth in Section 3 of this Agreement, the offer, sale and issuance of the Notes and the Warrants as contemplated by this Agreement are exempt from the registration requirements of the Act and will not result in a violation of the qualification or registration requirements of the any applicable state securities laws, and neither the Company nor any authorized agent acting on its behalf will take any action hereafter that would cause the loss of such exemption.
