As of their respective dates, the SEC Reports complied in all material respects with the requirements of the Securities Act of 1933, as amended (the "Securities Act") and the Exchange Act and the rules and regulations of the Commission promulgated thereunder, and none of the SEC Reports contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports, as the same may have been amended or superseded by a subsequently filed SEC Report, comply in all material respects with applicable accounting requirements and the rules and regulations of the Commission with respect thereto as in effect at the time of filing. Such financial statements have been prepared in all material respects in accordance with United States generally accepted accounting principles applied on a consistent basis during the periods involved ("GAAP"), except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements may not contain footnotes required by GAAP, and fairly present in all material respects the financial position of the Company as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, year-end audit adjustments.

2.6 Private Placement. Neither the Company nor any of its Subsidiaries or affiliates, nor any Person acting on its or their behalf, (i) has engaged in any form of general solicitation or general advertising (within the meaning of Regulation D under the Securities Act) in connection with the offer or sale of the Bridge Notes and Warrants, (ii) has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under any circumstances that would require registration of the Bridge Notes, Warrants and Common Stock issuable upon the exercise thereof, respectively, under the Securities Act or (iii) has issued any securities, including Common Stock or shares of any series of preferred stock or other securities or instruments convertible into, exchangeable for or otherwise entitling the holder thereof to acquire shares of Common Stock, which, if integrated with the sale of the Bridge Notes or Warrants for purposes of the Securities Act, would render the exemptions from registration relied upon unavailable, or trigger any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange on which any of the securities of the Company are listed, nor will the Company or any of its Subsidiaries or affiliates take any action or steps that would require registration of any of the Bridge Notes, Warrants or Common Stock issuable upon the exercise thereof under the Securities Act or cause the offering thereof to be integrated with other offerings if, as a result of such integration, the exemptions from registration relied upon in connection with the sale of the Bridge Notes and Warrants, would be unavailable. Assuming the accuracy of the representations and warranties of the Bridge Investors, the offer and sale of the Bridge Notes, Warrants and Common Stock issuable upon the exercise thereof by the Company to the Bridge Investors pursuant to this Agreement will be exempt from the registration requirements of the Securities Act.

2.7 Investment Company Status. The Company is not and upon consummation of the sale of the Bridge Notes, Warrants or Common Stock issuable upon the exercise thereof will not be an "investment company," a company controlled by an "investment company" or an "affiliated person" of, or "promoter" or "principal underwriter" for, an "investment company" as such terms are defined in the Investment Company Act of 1940, as amended.

REPRESENTATIONS AND WARRANTIES OF THE INVESTORS

Each Bridge Investor, severally and not jointly, represents and warrants to the Company that, the statements contained in this Article III are true and correct as of the Closing Date applicable to such Bridge Investor as though made as of the Closing Date, except to the extent such representations and warranties are specifically made as of a particular date (in which case such representations and warranties are true and correct as of such date).

3.1           Bridge Investor is an "accredited investor" as defined by Rule 501 of Regulation D, and Bridge Investor is capable of evaluating the merits and risks of its investment in the Closing Securities (with respect to the Bridge Investors) and has the ability and capacity to protect its interests. The Bridge Investor has accurately completed, signed and returned a questionnaire to the Company or its representative indicated the Bridge Investor is an "accredited investor." If Bridge Investor is a corporation, partnership or other entity, such Bridge Investor has not been formed for the specific purpose of acquiring the Closing Securities or the Warrant Shares, as the case may be; or, if Bridge Investor was so formed, each beneficial owner of Bridge Investor is an accredited investor. The Bridge Investor is not a broker-dealer under Section 15 of the Exchange Act or an officer, director or affiliate of the Company under Rule 144.

3.2           Bridge Investor understands that, except as set forth in Section 5.2 of this Agreement, the Closing Securities and the Warrant Shares have not been registered under the Act on the ground that the issuance thereof is exempt under Section 4(2) of the Act and/or Regulation D as a transaction by an issuer not involving any public offering and that, in the view of the Commission, the statutory basis for the exception claimed would not be present if any of the representations and warranties of Bridge Investor contained in this Agreement are untrue or, notwithstanding the Bridge Investor's representations and warranties, the Bridge Investor currently has in mind acquiring any of the Closing Securities for resale.

3.3           Bridge Investor is purchasing the Closing Securities, as applicable, and, in the event that the Bridge Investor should acquire any Warrant Shares, will be acquiring such Warrant Shares, as principal for its own account, and not for the benefit of any other Person, 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, except selling, transferring, or disposing of the Closing Securities and Warrant Shares, as applicable, in full compliance with all applicable provisions of the Act, the rules and regulations promulgated by the Commission thereunder, and applicable state securities laws; and that an investment in the Closing Securities and Warrant Shares is not a liquid investment.

3.4           Bridge Investor confirms that Bridge Investor 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 Bridge Investor.  In connection therewith, Bridge Investor acknowledges that Bridge Investor 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.  Bridge Investor has received and reviewed all the information concerning the Company and the Closing Securities, both written and oral, that Bridge Investor desires.  Without limiting the generality of the foregoing, Bridge Investor has been furnished with or has had the opportunity to acquire, and to review: all information, both written and oral, that Bridge Investor desires with respect to the Company's business, management, financial affairs and prospects.  In determining whether to make this investment, Bridge Investor has relied solely on Bridge Investor's own knowledge and understanding of the Company and its business based upon Bridge Investor's own due diligence investigations and the Company's filings with the Commission.

3.5           Bridge Investor has all requisite legal and other power and authority to execute and deliver this Agreement and to carry out and perform its obligations under the terms of this Agreement.  This Agreement constitutes a valid and legally binding obligation of Bridge Investor enforceable in accordance with its terms, subject as to enforcement, to bankruptcy, insolvency, reorganization and other laws of general applicability relating to or affecting creditors' rights and to general equity principles.

3.6           Bridge Investor has carefully considered and has discussed with its legal, tax, accounting and financial advisors, to the extent the Bridge Investor has deemed necessary, the suitability of this investment and the transactions contemplated by this Agreement for the Bridge Investor's particular federal, state, provincial, 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 the Bridge Investor.  Bridge Investor understands that it (and not the Company) shall be responsible for Bridge Investor's own tax liability that may arise as a result of the investment in the Closing Securities or the transactions contemplated by this Agreement, except as provided in Section 6.1(b).

3.7           Bridge Investor acknowledges that an investment in the Closing Securities is speculative and involves a high degree of risk and that Bridge Investor can bear the economic risk of the acceptance of the Closing Securities, including a total loss of its investment.  Bridge Investor recognizes and understands that no federal, state, provincial or foreign agency has recommended or endorsed the purchase of the Closing Securities.  Bridge Investor acknowledges that it has such knowledge and experience in financial and business matters that Bridge Investor is capable of evaluating the merits and risks of an investment in the Closing Securities and of making an informed investment decision with respect thereto.

3.8           Because of the legal restrictions imposed on resale or transfer of the Closing Securities, Bridge Investor understands that the Company shall have the right to note stop-transfer instructions in its records, and Bridge Investor has been informed of the Company's intention to do so.  Any sales, transfers, or other dispositions of the Closing Securities by Bridge Investor, if any, will be made in compliance with the Act and any other applicable securities laws, and all applicable rules and regulations promulgated thereunder and the terms of this Agreement.

3.9         The residency of Bridge Investor (or, in the case of a partnership, limited liability company or corporation, such entity's principal place of business) is correctly set forth below Bridge Investor's name on the signature page hereto.

3.10 If Bridge Investor is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986), such Bridge Investor hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Closing Securities or any use of this Agreement, including (i) the legal requirements within its jurisdiction for the purchase of the Closing Securities, (ii) any foreign exchange restrictions applicable to such purchase, (iii) any governmental or other consents that may need to be obtained and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Closing Securities. Such Bridge Investor's subscription and payment for, and his or her continued beneficial ownership of the Closing Securities (or the securities issuable upon the exercise of such securities), will not violate any applicable securities or other laws of Bridge Investor's jurisdiction. Such Bridge Investor also hereby represents that such Bridge Investor is not a "10-percent stockholder" as defined in Section 871(h) of the Internal Revenue Code of 1986. The funds used for the Bridge Notes do not violate the anti-money laundering provisions of the Money Laundering Control Act of 1986 or the Bank Secrecy Act of 1970, as amended by the USA Patriot Act of 2001.

6.10         No Third Party Reliance.  Anything contained herein to the contrary notwithstanding, the representations and warranties of the Company contained in this Agreement (a) are being given by the Company as an inducement to the Bridge Investors to enter into this Agreement and the other Transaction Documents (and the Company acknowledges that the Bridge Investors have expressly relied thereon) and (b) are solely for the benefit of the Bridge Investors.  Accordingly, no third party (including, without limitation, any holder of capital stock of the Company) or anyone acting on behalf of any holder thereof other than the Bridge Investors, and each of them, shall be a third-party or other beneficiary of such representations and warranties and no such third party shall have any rights of contribution against the Bridge Investors or the Company with respect to such representations or warranties or any matter subject to or resulting in indemnification under this Agreement or otherwise, provided, however, that notwithstanding the foregoing, Advanced Equities, Inc. and its affiliates, including, without limitation, Advanced Equities Financial Corp. shall be deemed to be an intended third party beneficiary under this Agreement as if Advanced Equities, Inc. and its affiliates were Bridge Investors.

6.11         Publicity.  Neither the Bridge Investors nor the Company shall issue any press release or make any public disclosure regarding the transactions contemplated hereby unless such press release or public disclosure is approved by the Required Holders and those parties mentioned in such press release or public disclosure in advance.  Notwithstanding the foregoing, each of the parties hereto may, in documents required to be filed by it with the Commission or other regulatory bodies, make such statements with respect to the transactions contemplated hereby as each may be advised by counsel is legally necessary or advisable.

6.12         Severability.  It is the desire and intent of the parties that the provisions of this Agreement be enforced to the fullest extent permissible under the law and public policies applied in each jurisdiction in which enforcement is sought.  Accordingly, in the event that any provision of this Agreement would be held in any jurisdiction to be invalid, prohibited or unenforceable for any reason, such provision, as to such jurisdiction, shall be ineffective, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any jurisdiction.  Notwithstanding the foregoing, if such provision could be more narrowly drawn so as to not be invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such jurisdiction, be so narrowly drawn, without invalidating the remaining provisions of this Agreement or affecting the validity or enforceability of such provision in any other jurisdiction.

6.13         Independence of Agreements, Covenants, Representations and Warranties.  All agreements and covenants hereunder shall be given independent effect so that if a certain action or condition constitutes a default under a certain agreement or covenant, the fact that such action or condition is permitted by another agreement or covenant shall not affect the occurrence of such default, unless expressly permitted under an exception to such covenant.  In addition, all representations and warranties hereunder shall be given independent effect so that if a particular representation or warranty proves to be incorrect or is breached, the fact that another representation or warranty concerning the same or similar subject matter is correct or is not breached will not affect the incorrectness of or a breach of a representation and warranty hereunder.  The annexes, exhibits and schedules attached hereto are hereby made part of this Agreement in all respects.

6.14         Counterparts; Facsimile and Electronic Signatures.  This Agreement may be executed in any number of counterparts, and each such counterpart hereof shall be deemed to be an original instrument, but all such counterparts together shall constitute but one agreement.  Counterpart signatures to this Agreement delivered by facsimile or other electronic transmission shall be acceptable and binding.

6.15         Headings.  The section and paragraph headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.
