          (aa) ERISA. No liability to the Pension Benefit Guaranty Corporation has been incurred with respect to any Plan by the Company or any of its Subsidiaries which is or would be materially adverse to the Company and its Subsidiaries. The execution and delivery of this Agreement and the issuance and sale of the Securities will not involve any transaction which is subject to the prohibitions of Section 406 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) or in connection with which a tax could be imposed pursuant to Section 4975 of the Internal Revenue Code of 1986, as amended, provided that, if any of the Purchasers, or any person or entity that owns a beneficial interest in any of the Purchasers, is an “employee pension benefit plan” (within the meaning of Section 3(2) of ERISA) with respect to which the Company is a “party in interest” (within the meaning of Section 3(14) of ERISA), the requirements of Sections 407(d)(5) and 408(e) of ERISA, if applicable, are met. As used in this Section 2.1(aa), the term “Plan” shall mean an “employee pension benefit plan” (as defined in Section 3 of ERISA) which is or has been established or maintained, or to which contributions are or have been made, by the Company or any Subsidiary or by any trade or business, whether or not incorporated, which, together with the Company or any Subsidiary, is under common control, as described in Section 414(b) or (c) of the Code.

          (bb) Independent Nature of Purchasers. The Company acknowledges that the obligations of each Purchaser under the Transaction Documents are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under the Transaction Documents. The Company acknowledges that the decision of each Purchaser to purchase Securities pursuant to this Agreement has been made by such Purchaser independently of any other Purchaser and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company or of its Subsidiaries which may have made or given by any other Purchaser or by any agent or employee of any other Purchaser, and no Purchaser or any of its agents or employees shall have any liability to any Purchaser (or any other person) relating to or arising from any such information, materials, statements or opinions. The Company acknowledges that nothing contained herein, or in any Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. The Company acknowledges that for reasons of administrative convenience only, the Transaction Documents have been prepared by counsel for one of the Purchasers and such counsel does not represent all of the Purchasers but only such Purchaser and the other Purchasers have retained their own individual counsel with respect to the transactions contemplated hereby.  The Company acknowledges that it has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by the Purchasers. The Company acknowledges that such procedure with respect to the Transaction Documents in no way creates a presumption that the Purchasers are in any way acting in concert or as a group with respect to the Transaction Documents or the transactions contemplated hereby or thereby. The Company acknowledges that each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

          (cc) No Integrated Offering. 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 the offering of the Securities pursuant to this Agreement to be integrated with prior offerings by the Company for purposes of the Securities Act which would prevent the Company from selling the Securities pursuant to Regulation D and Rule 506 thereof under the Securities Act, or any applicable exchange-related stockholder approval provisions, nor will the Company or any of its affiliates or subsidiaries take any action or steps that would cause the offering of the Securities to be integrated with other offerings. The Company does not have any registration statement pending before the Commission or currently under the Commission’s review and except as set forth on Schedule 2.1(cc) hereto, since January 1, 2007, the Company has not offered or sold any of its equity securities or debt securities convertible into shares of Common Stock.

          (dd) [Reserved].

12

          (ee) DTC Status. Except as set forth on Schedule 2.1(ee) hereto, the Company’s transfer agent is a participant in and the Common Stock is eligible for transfer pursuant to the Depository Trust Company Automated Securities Transfer Program. The name, address, telephone number, fax number, contact person and email of the Company transfer agent is set forth on Schedule 2.1(ee) hereto.

          Section 2.2 Representations and Warranties of the Purchasers. Each of the Purchasers hereby represents, warrants and covenants to the Company with respect solely to itself and not with respect to any other Purchaser as follows as of the date hereof and as of the Closing Date:

          (a) Organization and Standing of the Purchasers. If the Purchaser is an entity, such Purchaser is a corporation, limited liability company or partnership duly incorporated or organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation or organization.

          (b) Authorization and Power. Each Purchaser has the requisite power and authority to enter into and perform the Transaction Documents and to purchase the Securities being sold to it hereunder. The execution, delivery and performance of the Transaction Documents by each Purchaser and the consummation by it of the transactions contemplated hereby have been duly authorized by all necessary corporate or partnership action, and no further consent or authorization of such Purchaser or its Board of Directors, stockholders, members, or partners, as the case may be, is required. When executed and delivered by the Purchasers, the other Transaction Documents shall constitute valid and binding obligations of each Purchaser enforceable against such Purchaser in accordance with their terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation, conservatorship, receivership or similar laws relating to, or affecting generally the enforcement of, creditor’s rights and remedies or by other equitable principles of general application.

          (c) Acquisition for Investment. Each Purchaser is purchasing the Securities solely for its own account and not with a view to or for sale in connection with distribution. Each Purchaser does not have a present intention to sell any of the Securities, nor a present arrangement (whether or not legally binding) or intention to effect any distribution of any of the Securities to or through any person or entity; provided, however, that by making the representations herein, such Purchaser does not agree to hold the Securities for any minimum or other specific term and reserves the right to dispose of the Securities at any time in accordance with Federal and state securities laws applicable to such disposition. Each Purchaser acknowledges that it (i) has such knowledge and experience in financial and business matters such that Purchaser is capable of evaluating the merits and risks of Purchaser’s investment in the Company, (ii) is able to bear the financial risks associated with an investment in the Securities and (iii) has been given full access to such records of the Company and the Subsidiaries and to the officers of the Company and the Subsidiaries as it has deemed necessary or appropriate to conduct its due diligence investigation.

          (d) Rule 144. Each Purchaser understands that the Securities must be held indefinitely unless such Securities are registered under the Securities Act or an exemption from registration is available. Each Purchaser acknowledges that such person is familiar with Rule

13

144 of the rules and regulations of the Commission, as amended, promulgated pursuant to the Securities Act (“Rule 144”), and that such Purchaser has been advised that Rule 144 permits resales only under certain circumstances. Each Purchaser understands that to the extent that Rule 144 is not available, such Purchaser will be unable to sell any Securities without either registration under the Securities Act or the existence of another exemption from such registration requirement.

          (e) General. Each Purchaser understands that the Securities are being offered and sold in reliance on a transactional exemption from the registration requirements of federal and state securities laws and the Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein in order to determine the applicability of such exemptions and the suitability of such Purchaser to acquire the Securities. Each Purchaser understands that no United States federal or state agency or any government or governmental agency has passed upon or made any recommendation or endorsement of the Securities. Commencing on the date that the Purchasers were initially contacted regarding an investment in the Securities, none of the Purchasers has engaged in any short sale of the Common Stock and will not engage (or instruct any third party to engage on the Purchaser’s behalf) in any short sale of the Common Stock prior to Closing hereunder. Each Purchaser covenants and agrees that (i) it will comply with its internal policies and procedures regarding short sales of securities registered under the Exchange Act, (ii) it will not engage in any short sale of the Common Stock until after the pubic announcement of the Closing hereunder, and (iii) it will not be in a “net short” position with respect to the shares of Common Stock for so long as the Purchaser beneficially owns shares of Series A-2 Preferred Stock. For purposes of this Section 2.2(e), a “net short position” means a sale of Common Stock by a Purchaser that is marked as a short sale and that is made at a time when there is no equivalent offsetting long position in Common Stock (or securities convertible or exchangeable into Common Stock) held by such Purchaser.

          (f) No General Solicitation. Each Purchaser acknowledges that the Securities were not offered to such Purchaser by means of any form of general or public solicitation or general advertising, or publicly disseminated advertisements or sales literature, including (i) any advertisement, article, notice or other communication published in any newspaper, magazine, or similar media, or broadcast over television or radio, or (ii) any seminar or meeting to which such Purchaser was invited by any of the foregoing means of communications. Each Purchaser, in making the decision to purchase the Securities, has relied upon independent investigation made by it and has not relied on any information or representations made by third parties.

          (g) Accredited Investor. Each Purchaser (i) is an “accredited investor” (as defined in Rule 501 of Regulation D), (ii) has such experience in business and financial matters that it is capable of evaluating the merits and risks of an investment in the Securities, and (iii) has completed an accredited investor certification in the form attached as Exhibit D hereto. Such Purchaser is not required to be registered as a broker-dealer under Section 15 of the Exchange Act and such Purchaser is not a broker-dealer. Each Purchaser acknowledges that an investment in the Securities is speculative and involves a high degree of risk.

          (h) Independent Investment. No Purchaser has agreed to act with any other Purchaser for the purpose of acquiring, holding, voting or disposing of the Securities purchased

14

hereunder for purposes of Section 13(d) under the Exchange Act, and each Purchaser is acting independently with respect to its investment in the Securities.

ARTICLE III

COVENANTS

     The Company covenants with each Purchaser as follows, which covenants are for the benefit of each Purchaser and their respective permitted assignees.

          Section 3.1 Securities Compliance. The Company shall notify the Commission in accordance with its rules and regulations, of the transactions contemplated by any of the Transaction Documents and shall take all other necessary action and proceedings as may be required and permitted by applicable law, rule and regulation, for the legal and valid issuance of the Securities to the Purchasers, or their respective subsequent holders.

          Section 3.2 Registration and Listing. The Company shall cause its Common Stock to continue to be registered under Sections 12(b) or 12(g) of the Exchange Act, to comply in all respects with its reporting and filing obligations under the Exchange Act and to not take any action or file any document (whether or not permitted by the Securities Act or the rules promulgated thereunder) to terminate or suspend such registration or to terminate or suspend its reporting and filing obligations under the Exchange Act, except as permitted herein. The Company will take all action necessary to continue the listing or trading of its Common Stock on the OTC Bulletin Board or other exchange or market on which the Common Stock is trading. If required, the Company will promptly file the “Listing Application” for, or in connection with, the issuance and delivery of the Conversion Shares and the Warrant Shares. Subject to the terms of the Transaction Documents, the Company further covenants that it will take such further action as the Purchasers may reasonably request, all to the extent required from time to time to enable the Purchasers to sell the Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act. Upon the request of the Purchasers, the Company shall deliver to the Purchasers a written certification of a duly authorized officer as to whether it has complied with such requirements.

          Section 3.3 Inspection Rights. Provided same would not be in violation of Regulation FD, the Company shall permit, during normal business hours and upon reasonable request and reasonable notice, each Purchaser or any employees, agents or representatives thereof, so long as such Purchaser shall be obligated hereunder to purchase the Series A-2 Preferred Stock or shall beneficially own any Conversion Shares or Warrant Shares, for purposes reasonably related to such Purchaser’s interests as a stockholder, to examine the publicly available, non-confidential records and books of account of, and visit and inspect the properties, assets, operations and business of the Company and any Subsidiary, and to discuss the publicly available, non-confidential affairs, finances and accounts of the Company and any Subsidiary with any of its officers, consultants, directors, and key employees.

          Section 3.4 Compliance with Laws. The Company shall comply, and cause each Subsidiary to comply, with all applicable laws, rules, regulations and orders, noncompliance with which would be reasonably likely to have a Material Adverse Effect.

15

          Section 3.5 Keeping of Records and Books of Account. The Company shall keep and cause each Subsidiary to keep adequate records and books of account, in which complete entries will be made in accordance with GAAP consistently applied, reflecting all financial transactions of the Company and its Subsidiaries, and in which, for each fiscal year, all proper reserves for depreciation, depletion, obsolescence, amortization, taxes, bad debts and other purposes in connection with its business shall be made.

          Section 3.6 Reporting Requirements. If the Company ceases to file its periodic reports with the Commission, or if the Commission ceases making these periodic reports available via the Internet without charge, then the Company shall furnish the following to each Purchaser so long as such Purchaser shall be obligated hereunder to purchase the Securities or shall beneficially own Series A-2 Preferred Stock:

          (a) Quarterly Reports filed with the Commission on Form 10-Q as soon as practical after the document is filed with the Commission, and in any event within five (5) days after the document is filed with the Commission;

          (b) Annual Reports filed with the Commission on Form 10-K as soon as practical after the document is filed with the Commission, and in any event within five (5) days after the document is filed with the Commission; and

          (c) Copies of all notices, information and proxy statements in connection with any meetings, that are, in each case, provided to holders of shares of Common Stock, contemporaneously with the delivery of such notices or information to such holders of Common Stock.

          Section 3.7 Other Agreements. The Company shall not enter into any agreement in which the terms of such agreement would restrict or impair the right or ability to perform of the Company or any Subsidiary under any Transaction Document.

          Section 3.8 Use of Proceeds. The proceeds from the sale of the Securities hereunder shall be used by the Company for working capital and general corporate purposes, and not to redeem any Common Stock or securities convertible, exercisable or exchangeable into Common Stock or to settle any outstanding litigation.

          Section 3.9 Reporting Status. So long as a Purchaser beneficially owns any of the Securities, the Company shall timely file all reports required to be filed with the Commission pursuant to the Exchange Act, and the Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would permit such termination.

          Section 3.10 Disclosure of Transaction. The Company shall file with the Commission a Current Report on Form 8-K (the “Form 8-K”) describing the material terms of the transactions contemplated hereby (and attaching as exhibits thereto this Agreement, the Certificate of Designation, Preferences and Rights of the Series A-2 Preferred Stock, and the form of Warrant) as soon as practicable following the Closing Date but in no event more than

16

four (4) Trading Days following the Closing Date. “Trading Day” means any day during which the principal exchange on which the Common Stock is traded shall be open for trading.

          Section 3.11 [Reserved]

          Section 3.12 Pledge of Securities. The Company acknowledges that the Securities may be pledged by a Purchaser in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Securities. The pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no Purchaser effecting a pledge of the Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document; provided that a Purchaser and its pledgee shall be required to comply with the provisions of Article V hereof in order to effect a sale, transfer or assignment of Securities to such pledgee. At the Purchasers’ expense, the Company hereby agrees to execute and deliver such documentation as a pledgee of the Securities may reasonably request in connection with a pledge of the Securities to such pledgee by a Purchaser.

          Section 3.13 Amendments. The Company shall not amend or waive any provision of the Articles or Bylaws of the Company in any way that would adversely affect exercise rights, voting rights, conversion rights, prepayment rights or redemption rights of the holder of the Series A-2 Preferred Stock or the Warrants.

          Section 3.14 Distributions. Except as set forth on Schedule 3.14, so long as any Series A-2 Preferred Stock or Warrants remain outstanding, the Company agrees that it shall not, and shall not permit any Subsidiary to, (i) declare or pay any dividends or make any distributions to any holder(s) of Common Stock (or security convertible into or exercisable for Common Stock) or (ii) purchase or otherwise acquire for value, directly or indirectly, any Common Stock or other equity security of the Company.

          Section 3.15 Reservation of Shares. So long as any of the Series A-2 Preferred Stock or Warrants remain outstanding, the Company shall take all action necessary to have authorized and reserved for the purpose of issuance, one hundred percent (100%) of the Conversion Shares and the Warrant Shares.

          Section 3.16 Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent, and any subsequent transfer agent, to issue certificates, registered in the name of each Purchaser or its respective nominee(s), for the Conversion Shares and the Warrant Shares in such amounts as specified from time to time by each Purchaser to the Company upon conversion of the Series A-2 Preferred Stock or exercise of the Warrants in the form of Exhibit E attached hereto (the “Irrevocable Transfer Agent Instructions”). Prior to registration of the Conversion Shares and the Warrant Shares under the Securities Act, all such certificates shall bear the restrictive legend specified in Section 5.1 of this Agreement. The Company warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 3.16 will be given by the Company to its transfer agent and that the Conversion Shares and Warrant Shares shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement. Nothing in this Section 3.16 shall affect in any way each Purchaser’s obligations and agreements set forth in Section 5.1

17

to comply with all applicable prospectus delivery requirements, if any, upon resale of the Conversion Shares and the Warrant Shares. If a Purchaser provides the Company with an opinion of counsel, in a generally acceptable form, to the effect that a public sale, assignment or transfer of the Conversion Shares or Warrant Shares may be made without registration under the Securities Act or the Purchaser provides the Company with reasonable assurances that the Conversion Shares or Warrant Shares can be sold pursuant to Rule 144 without any restriction as to the number of securities acquired as of a particular date that can then be immediately sold, the Company shall permit the transfer, and, in the case of the Conversion Shares and the Warrant Shares, promptly instruct its transfer agent to issue one or more certificates in such name and in such denominations as specified by such Purchaser and without any restrictive legend. The Company acknowledges that a breach by it of its obligations under this Section 3.16 will cause irreparable harm to the Purchasers by vitiating the intent and purpose of the transaction contemplated hereby. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 3.16 will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 3.16, that the Purchasers shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

          Section 3.17 Opinions. The Company will provide, at the Company’s expense, such legal opinions in the future as are reasonably necessary for the issuance and resale of the Conversion Shares and the Warrant Shares pursuant to an effective registration statement, Rule 144 under the Securities Act or another exemption from registration. In the event that Common Stock is sold in a manner that complies with an exemption from registration, the Company will promptly instruct its counsel (at its expense) to issue to the transfer agent an opinion permitting removal of the legend (indefinitely, if permitted pursuant to Rule 144 of the Securities Act, or otherwise to permit sale of the shares pursuant to Rule 144 of the Securities Act).

INDEMNIFICATION

          Section 6.1 General Indemnity. The Company agrees to indemnify and hold harmless the Purchasers (and their respective directors, officers, affiliates, agents, successors and assigns) from and against any and all losses, liabilities, deficiencies, costs, damages and expenses (including, without limitation, reasonable attorneys’ fees, charges and disbursements) incurred by the Purchasers as a result of any inaccuracy in or breach of the representations, warranties or covenants made by the Company herein.

          Section 6.2 Indemnification Procedure. Any party entitled to indemnification under this Article VI (an “indemnified party”) will give written notice to the indemnifying party of any matter giving rise to a claim for indemnification; provided, that the failure of any party entitled to indemnification hereunder to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Article VI except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action, proceeding or claim is brought against an indemnified party in respect of which indemnification is sought hereunder, the indemnifying party shall be entitled to participate in and, unless in the reasonable judgment of the indemnifying party a conflict of interest between it and the indemnified party exists with respect to such action, proceeding or claim (in which case the indemnifying party shall be responsible for the reasonable fees and expenses of one separate counsel for the indemnified parties), to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. In the event that the indemnifying party advises an indemnified party that it will contest such a claim for indemnification hereunder, or fails, within thirty (30) days of receipt of any indemnification notice to notify, in writing, such person of its election to defend, settle or compromise, at its sole cost and expense, any action, proceeding or

21

claim (or discontinues its defense at any time after it commences such defense), then the indemnified party may, at its option, defend, settle or otherwise compromise or pay such action or claim. In any event, unless and until the indemnifying party elects in writing to assume and does so assume the defense of any such claim, proceeding or action, the indemnified party’s costs and expenses arising out of the defense, settlement or compromise of any such action, claim or proceeding shall be losses subject to indemnification hereunder. The indemnified party shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the indemnified party which relates to such action or claim. The indemnifying party shall keep the indemnified party fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. If the indemnifying party elects to defend any such action or claim, then the indemnified party shall be entitled to participate in such defense with counsel of its choice at its sole cost and expense. The indemnifying party shall not be liable for any settlement of any action, claim or proceeding effected without its prior written consent. Notwithstanding anything in this Article VI to the contrary, the indemnifying party shall not, without the indemnified party’s prior written consent, settle or compromise any claim or consent to entry of any judgment in respect thereof which imposes any future obligation on the indemnified party or which does not include, as an unconditional term thereof, the giving by the claimant or the plaintiff to the indemnified party of a release from all liability in respect of such claim. The indemnification obligations to defend the indemnified party required by this Article VI shall be made by periodic payments of the amount thereof during the course of investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred, so long as the indemnified party shall refund such moneys if it is ultimately determined by a court of competent jurisdiction that such party was not entitled to indemnification. The indemnity agreements contained herein shall be in addition to (a) any cause of action or similar rights of the indemnified party against the indemnifying party or others, and (b) any liabilities the indemnifying party may be subject to pursuant to the law.

ARTICLE VII
