SECTION 4.

REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

Each Purchaser severally represents and warrants to the Company both as of the date hereof and again as of the Closing, as to such Purchaser only, as follows:

4.1 Experience; Accredited Investor. Such Purchaser is a sophisticated investor and has experience in evaluating and investing in private placement transactions of securities in companies similar to the Company so that such Purchaser is capable of evaluating the merits and risks of his investment in the Company and has the capacity to protect such Purchaser’s own interests. Further, such Purchaser recognizes that an investment in the Company is highly speculative and involves significant risks (including those identified in the SEC Reports) including a complete loss of such investment. In addition, such Purchaser is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act and has accurately completed the questionnaire attached hereto as Exhibit B. Such Purchaser (i) has no need for liquidity in the investment in the Shares, (ii) is able to bear the substantial economic risk of an investment in the Shares for an indefinite period and (iii) could afford the complete loss of such Purchaser’s investment in the Shares.

4.2 Investment. Such Purchaser is acquiring the Shares for investment for such Purchaser’s own account, not as a nominee or agent, and not with the view to, or for resale in connection with, any distribution thereof. Such Purchaser has not offered or sold any portion of the Shares to be acquired by it and has no present intention of reselling or otherwise disposing of any portion of such Shares either currently or after the passage of a fixed or determinable period of time or upon the occurrence or nonoccurrence of any predetermined event or circumstance. Such Purchaser understands that the Shares to be purchased have not been, and will not be, registered under the Securities Act or qualified under applicable blue sky or other state securities laws by reason of specific exemptions from the registration provisions of the Securities Act and the qualification provisions of applicable blue sky and other state securities laws, the availability of which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of such Purchaser’s representations as expressed herein. Such Purchaser understands that no Federal or state agency has passed upon the Shares or made any finding or determination as to the fairness of the investment or any recommendation or endorsement of the Shares. Such Purchaser acknowledges that the Shares must be held indefinitely unless subsequently registered under the Securities Act or unless an exemption from such registration is available. Such Purchaser is aware of the provisions of Rule 144 promulgated under the Securities Act, which permit limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions. In acquiring the Shares, such Purchaser is acting on such Purchaser’s own behalf and is not acting together with any other person or entity (including any other Purchasers) for the purpose of acquiring, holding, voting or disposing of the Shares within the meaning of Section 13(d) of the Exchange Act. If such Purchaser is not a natural person, it was not formed solely for purposes of making this investment. Unless such Purchaser has otherwise notified the Company in writing, such Purchaser is not, and has not been within the 90 days prior to the Closing Date, an officer, director, employee, agent or affiliate of the Company or of any other Purchaser. Unless such Purchaser has otherwise notified the Company in writing, such Purchaser is not a broker or dealer of securities, nor prior to the Closing Date is such Purchaser the beneficial owner of 5% or

more of the Common Stock. Such Purchaser has not prior to the date hereof directly or indirectly, through related parties, affiliates or otherwise (a) sold “short” or “short against the box” (as those terms are generally understood) any equity security of the Company; or (b) otherwise engaged in any transaction which involves hedging of its position in, or reducing of its economic exposure to, the securities of the Company.

Such Purchaser has had an opportunity to discuss the Company’s business, management and financial affairs with its management and has had the opportunity to review the Company’s facilities. Such Purchaser also has had opportunity to ask questions of officers of the Company. Such Purchaser’s taking advantage of any such opportunity however, does not limit or modify the representations and warranties of the Company in Section 3 hereof or the right of any of the Purchasers to rely thereon. Such Purchaser has relied solely upon the information provided by the Company in the SEC Reports and this Agreement in making the decision to invest in the Shares.

4.4 Authorization. Such Purchaser has all requisite power and authority to execute and deliver this Agreement and to carry out and perform its obligations under the terms of this Agreement. If such Purchaser is a corporation or other entity, all corporate action on the part of such Purchaser, such Purchaser’s directors and stockholders (or similar action on the part of such Purchaser if it is an entity other than a corporation) necessary for the authorization, execution, delivery and performance of this Agreement by such Purchaser, the purchase of the Shares and the performance of all of such Purchaser’s obligations hereunder has been taken or will be taken prior to the Closing. This Agreement constitutes the valid and legally binding obligation of such Purchaser, enforceable in accordance with its terms, except as such enforcement is subject to the effect of (i) any applicable bankruptcy, insolvency, reorganization or other laws relating to or affecting creditors’ rights generally, and (ii) general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

4.5 Address and Social Security or Taxpayer Identification Number. The address and social security or taxpayer identification number set forth opposite such Purchaser’s name on the Purchaser Address and Social Security or Taxpayer Identification Number Schedule attached hereto as Exhibit A-1 are true and correct, such address is such Purchaser’s resident or principal place of business, and such Purchaser has no present intention of changing such residence or principal place of business to any other state or jurisdiction.

4.6 Litigation, etc. There is no action, suit, proceeding or investigation pending or, to such Purchaser’s knowledge, currently threatened against such Purchaser that questions the validity of this Agreement or the right of such Purchaser to enter into such agreement, or to consummate the transactions contemplated hereby, or that would reasonably be expected to materially adversely affect such Purchaser’s ability to consummate the transaction contemplated hereby.

4.7 Governmental Consent, etc. No consent, approval or authorization of or designation, declaration or filing with any governmental authority on the part of such Purchaser is required in connection with the execution, delivery and performance of this Agreement.

4.8 Brokers or Finders. Such Purchaser has not incurred, and will not incur, directly or indirectly, as a result of any action taken by such Purchaser, any liability for brokerage or finders’ fees or agents’ commissions or any similar charge in connection with this Agreement.

SECTION 7.

RESTRICTIONS ON TRANSFERABILITY OF SHARES;

COMPLIANCE WITH SECURITIES ACT

7.1 Restrictions on Transferability. Each Purchaser acknowledges that the Shares, the Warrant Shares and the Warrants referred to herein are “restricted securities” as such term is defined in Rule 144(a)(3) under the Securities Act. Each Purchaser agrees that it has not and will not make any offer, sale or other transfer of the Shares, the Warrant Shares or the Warrants by any means which would not comply with applicable law or this Agreement or which would otherwise impose upon the Company any obligation to satisfy any public filing or

registration requirement. Each Purchaser further agrees that it will not offer, sell or transfer the Shares, the Warrant Shares or the Warrants unless:

(a)

there is then in effect a registration statement under the Securities Act covering such proposed disposition (the “Registration Statement”) and such disposition is made in accordance with the Registration Statement; or

(b)

such Purchaser shall have notified the Company of the proposed disposition and shall have furnished the Company with a statement of the circumstances surrounding the proposed disposition, and, if requested by the Company, it shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company that such disposition is exempt from registration of such shares under the Securities Act or any applicable state, foreign or other securities laws.

Each Purchaser acknowledges that the Company is under no obligation to aid such Purchaser in obtaining any exemption from registration requirements in connection with a proposed disposition. Each Purchaser also acknowledges that such Purchaser shall be responsible for compliance with all conditions on transfer imposed by any securities administrator of any state and for any expenses incurred by the Company for legal or accounting services in connection with reviewing such a proposed transfer and issuing opinions in connection therewith. Each Purchaser understands and agrees that any disposition of the Shares, the Warrant Shares or the Warrants in violation of this Agreement shall be null and void, and that no transfer of the Shares, the Warrant Shares or the Warrants shall be made by the Company or the transfer agent for the Common Stock upon the Company’s stock transfer books or records unless and until there has been compliance with the terms of this Agreement, the Securities Act, any applicable state and foreign securities law and any other laws. Each Purchaser agrees that it will not transfer the Shares, the Warrant Shares or the Warrants, other than pursuant to a Registration Statement or in a transaction that complies with Rule 144, unless the transferee agrees to be bound by the restrictions on transfer contained herein to the same extent as if it were an original Purchaser.

7.2 Restrictive Legend. Each certificate representing (i) the Shares, the Warrant Shares and the Warrants, and (ii) any other securities issued in respect of the Shares, the Warrant Shares and the Warrants upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall be stamped or otherwise imprinted with a legend in the following form:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. SUCH SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL OR OTHER EVIDENCE REASONABLY ACCEPTABLE TO IT THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF SAID ACT.

Each Purchaser consents to the Company making a notation on its records and giving instructions to any transfer agent of the Common Stock in order to implement the restrictions on transfer established in this Section 7. The certificates for Warrants and the Warrant Shares will include such legend as is specified in the Warrant Agreement.

SECTION 8.

COVENANTS

8.1 Fulfillment of Closing Conditions. The Company and each Purchaser agrees to use its commercially reasonable best efforts to cause the fulfillment of the closing conditions (to the extent, in whole or in part, within its or his direct or indirect control) set forth in Sections 5 and 6 hereof.

8.2 Confidentiality. For the purposes of this Section 8.2, the term “Confidential Information” means information delivered to any Purchaser by or on behalf of the Company or any Subsidiary of the Company in connection with the transactions contemplated by or otherwise pursuant to this Agreement (including, without limitation, any information regarding the transactions contemplated hereby provided prior to the Closing Date), provided that such term does not include information that (a) was publicly known or otherwise known to such Purchaser prior to the time of such disclosure, (b) subsequently becomes publicly known through no act or omission by any Purchaser or any person or entity acting on such Purchaser’s behalf, or (c) otherwise becomes known to any Purchaser other than through disclosure by the Company or any Subsidiary of the Company. Each Purchaser will maintain the confidentiality of such Confidential Information in accordance with procedures adopted by such Purchaser in good faith to protect confidential information of third parties delivered to such Purchaser, provided that such Purchaser may deliver or disclose Confidential Information to (i) its directors, officers, employees, agents, attorneys and affiliates (to the extent such disclosure reasonably relates to the administration of the investment represented by the purchased Shares), (ii) its financial advisors and other professional advisors who are made aware of the confidential nature of such information, (iii) any other Purchaser, or (iv) any other person or entity to which such delivery or disclosure may be necessary or appropriate (x) to effect compliance with any law, rule, regulation or order applicable to such Purchaser, (y) in response to any subpoena or other legal process or (z) in connection with any litigation to which such Purchaser is a party. Each Purchaser agrees to provide the Company with reasonable prior notice of any proposed delivery or disclosure of Confidential Information pursuant to clause (iv) of the foregoing sentence and to use commercially reasonable best efforts to cause the person or entity to which such delivery or disclosure is made to agree in writing prior to its receipt of such Confidential Information to be bound by the provisions of this Section 8.2. Each Purchaser hereby acknowledges that such Purchaser is aware, and that such Purchaser will advise its representatives who have knowledge of Confidential Information, that the United States securities laws prohibit any person who has material, non-public information concerning the Company from purchasing or selling securities of the Company or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that such person is likely to purchase or sell such securities, and such Purchaser agrees to comply and cause its representatives to comply with such laws.

8.3 Publicity. The Company and each Purchaser agrees not to issue any press release or make any public announcement with respect to this Agreement or the transactions contemplated hereby unless the prior written consents of the other parties hereto have been obtained, which consents shall not be unreasonably withheld; provided however, that the Company may make any public disclosure it believes in good faith is required by applicable law or any listing or trading agreement concerning its publicly-traded securities (in which case it will use its best efforts to advise the Purchasers prior to making such disclosure).
