The Company has the corporate power and authority to conduct its business as now being conducted and is duly licensed or qualified to do business and is in good standing as a foreign corporation in all jurisdictions in which the nature of the business conducted by it, and/or the character of the assets owned or leased by it, makes such qualification or licensure necessary, except for those jurisdictions in which the failure to be so qualified or licensed or to be in good standing would not, individually or in the aggregate, limit the Company’s ability to consummate the transactions hereby contemplated or have a Company Material Adverse Effect.

3.2 Subsidiaries All of the outstanding shares of the capital stock of each Subsidiary of the Company are owned by the Company free and clear of all Liens. Each of the Company’s Subsidiaries is set forth on Section 3.2 of the Company Disclosure Schedule and is a corporation or other legal entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization.

3.3 Authority; Execution and Delivery; Enforceability The Company has the corporate power and authority to execute and deliver this Agreement and the Transaction

Documents and to consummate the transactions hereby and thereby contemplated.

The Company has duly executed and delivered this Agreement and the Transaction Documents, and, assuming the due execution and delivery of this Agreement and the Transaction Documents by each party thereto (other than the Company), this Agreement and the Transaction Documents constitute valid and binding obligations of the Company and are enforceable against the Company in accordance with its and their respective terms, except as such enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally or general equitable principles (whether considered in a proceeding at equity or in law).

3.4 Non-Contravention Except as set forth on Schedule 3.4, neither the execution and delivery of this Agreement and the Transaction Documents by the Company, nor the consummation of the transactions hereby and thereby contemplated by the Company, will:

(i) constitute any violation or breach of the certificate of incorporation or the by-laws (or comparable organizational documents in the case of Subsidiaries) of the Company or any of its Subsidiaries;

(ii) constitute a default under or a violation or breach of, or result in the acceleration of any obligation under, any provision of any Contract to which the Company or any of its Subsidiaries is a party or by which any of the assets of the Company or any of its Subsidiaries or the Purchase Shares may be affected;

(iii) assuming the consents and approvals described in Section 3.7 have been received, violate any Governmental Rules affecting the Company or any of its Subsidiaries; or

3.6 Capitalization; Options. (a) The Company is authorized to issue 75,000,000 shares of Common Stock, 15,220,817 of which are issued and outstanding as of the date hereof, (“Common Stock”) and 1,000,000 shares of Preferred Stock, none of which are issued and outstanding as of the date hereof (prior to giving effect to the transactions contemplated by this Agreement and the Company’s Preferred Stock Purchase Agreement dated November 14, 2007).

(b) All of the Purchase Shares when issued to Buyers in accordance with the terms of

this Agreement shall be legally and validly issued, fully paid and non-assessable, free and clear of all Liens.

3.12 Agreements; Action Other than as attached as an exhibit to the Company’s public filings with the Securities and Exchange Commission, the Company is not a party to, and none of its properties, rights or assets are bound by, any material contract, agreement, lease, power of attorney, guaranty, surety arrangement, or other commitment, whether written or oral.

3.13 Related-Party Transactions No employee, officer or director of the Company or member of his or her immediate family is indebted to the Company, nor is the Company indebted (or committed to make loans or extend or guarantee credit) to any of them. Except as set forth in the Company’s SEC filings, none of such persons and no “affiliate” or “associate” (as those terms are defined in Rule 405 promulgated under the ▇▇▇▇ ▇▇▇) of any such person has had any direct or indirect ownership interest in, or other material interest in the Company, or any firm or corporation (i) with which the Company is affiliated, (ii) with which the Company has a business relationship, (iii) that competes with the Company, (iv) which purchases from or sells, licenses or furnishes to the Company any goods, property or services; or (v) which is a party to any contract or agreement to which the Company is a party or by which it may be bound or affected; provided, however that no representation or warranty is made with respect to stock in publicly traded companies that may compete with the Company owned by employees, officers or directors of the Company and members of their immediate families.

3.14 Title to Property and Assets Company has good and marketable title to all of its properties and assets, in each case, except as set forth in the SEC filings and except for liens arising from current taxes not yet due and payable, free and clear of any mortgages, pledges, liens, encumbrances, security interests or charges of any kind (collectively, “Encumbrances”).

3.15 Employee Benefit Plans Except as set forth on Schedule 3.15 attached hereto, neither the Company, nor any member of a controlled group (within the meaning of Sections 414(b), (c), (m) and (o) of the Code)) of employers that include the Company (collectively, the “Company Group”), maintains any “employee benefit plan” within the meaning of section 3(1) of the Employee Retirement Income Security Act of 1974, as amended) nor any other severance, bonus, incentive stock option, stock appreciation, stock purchase, retirement, insurance, profit sharing, deferred compensation welfare or fringe benefit plan, agreement or arrangement, whether written or unwritten, providing benefits for employees or former employees of the Company or members of the Company Group (including such arrangements contained within the provisions of an individual employment or consulting agreement).

The Company has never had any tax deficiency proposed or assessed against it and has not executed any waiver of any statute of limitations on the assessment or collection of any tax or governmental charge. None of the Company’s federal income tax returns and none of its state income or franchise tax or sales or use tax returns has ever been audited by governmental authorities, and no such audits are pending or, to the Company’s knowledge, threatened. Since the date of the Financial Statements, the Company has not incurred any taxes, assessments or governmental charges other than in the ordinary course of business. The Company has withheld or collected from each payment made to each of its employees, the amount of all taxes (including, but not limited to, federal income taxes, Federal Insurance Contribution Act taxes and Federal Unemployment Tax Act taxes) required to be withheld or collected therefrom, and has paid the same to the proper tax receiving officers or authorized depositories.

3.17 Insurance All insurance policies maintained by the Company are in full force and effect and the Company is not in default of any provision thereof. The Company has not received notice from any issuer of any such insurance policies of its intention to cancel or refusal to renew any policy issued by it.

3.18 Disclosure None of this Agreement or any other statements or certificates made or delivered in connection herewith or therewith contains or will contain any untrue statement of a material fact or omits or will omit to state a material fact required to be stated therein or necessary to make the statements herein or therein, in light of the circumstances in which they are made, not misleading.

Each certificate representing any of the foregoing shall bear legends in substantially the following form:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED EXCEPT (I) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT WITH RESPECT TO SUCH SECURITIES UNDER THE ACT, OR (II) UPON RECEIPT BY ISSUER OF AN OPINION OF LEGAL COUNSEL REASONABLY SATISFACTORY TO ISSUER THAT SUCH REGISTRATION IS NOT REQUIRED.

The Company shall remove or cause its registrar and transfer agent to remove such legend at the time such Purchase Shares or Conversion Shares are transferred pursuant to an effective registration statement under the Securities Act or pursuant to Rule 144 under the Securities Act.

5.4 Limitation on Affiliate Transactions Notwithstanding the inapplicability of

Section 203 of the Delaware General Corporation Law (“Section 203”) to the Company, the Buyers and the transactions contemplated hereby, each Buyer hereby agrees that, from and after the Closing and until the eighteen month anniversary thereof, the Company shall be prohibited from engaging in any “business combination” (as defined in Section 203) with such Buyer unless such business combination is approved by the holders of a majority of Common Stock of the Company, other than Buyers, entitled to vote at a meeting in respect thereof.

7.1 Survival; Certain Other Matters.

(a) The representations and warranties of the parties contained in this Agreement shall survive the Closing and shall continue in full force and effect until the second anniversary of the date hereof, after which time such representations and warranties shall terminate and have no further force or effect. The period during which any such representation or warranty survives is the “Survival Period” for such representation or warranty. Notwithstanding the foregoing, any representation or warranty that would otherwise terminate shall survive with respect to, and only with respect to, any matter of which notice is given to Company or Buyers, as the case may be, in writing pursuant to this Agreement prior to the end of the applicable Survival Period until such matter is resolved, after which time such representation and warranty shall terminate and have no further force or effect.

(b) The covenants and agreements of the parties contained in this Agreement shall survive the Closing as to each Buyer until such Buyer no longer owns any Purchase Shares or Conversion Shares.

7.2 Further Assurances From and after the Closing Date, each party shall, at any time and from time to time, make, execute and deliver, or cause to be made, executed and delivered, such instruments and agreements, and take or cause to be taken all such actions as counsel for the other party may reasonably request for the effectual consummation of this Agreement and the transactions hereby contemplated.

7.7 Severability If any provision of this Agreement or the application of any provision hereof to any person or circumstances is held invalid, the remainder of this Agreement and the application of such provision to other persons or circumstances shall not be affected unless the provision held invalid shall substantially impair the benefits of the remaining portions of this Agreement.

7.8 Assignment This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, executors, administrators, successors and permitted assigns. This Agreement may not be assigned by the Company or a Buyer without the prior written consent of the other party; provided, however, that, prior to Closing, each Buyer may assign its rights under this Agreement to any Affiliate of such Buyer that agrees in favor of the Company in writing to the assumption of the assigning Buyer’s obligations under this Agreement. No such assignment and assumption shall relieve the assigning Buyer of its obligations under this Agreement.

7.9 Governing Law; Jurisdiction.

(a) This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York applicable to contracts made and to be performed wholly within said State, without giving effect to the conflict of laws principles thereof.

(b) Each of the parties hereto irrevocably and unconditionally submits to the exclusive jurisdiction of the United States District Court for the Southern District of New York or, if such court will not accept jurisdiction, the Supreme Court of the State of New York, New York County or any court of competent civil jurisdiction sitting in New York County, New York. In any action, suit or other proceeding, each of the parties hereto irrevocably and unconditionally waives and agrees not to assert by way of motion, as a defense or otherwise any claims that it is not subject to the jurisdiction of the above courts, that such action or suit is brought in an inconvenient forum or that the venue of such action, suit or other proceeding is improper. Each of the parties hereto also agrees that any final and unappealable judgment against a party hereto in connection with any action, suit or other proceeding shall be conclusive and binding on such party and that such award or judgment may be enforced in any court of competent jurisdiction, either within or outside of the United States. A certified or exemplified copy of such award or judgment shall be conclusive evidence of the fact and amount of such award or judgment.

(c) EACH OF THE PARTIES HERETO IRREVOCABLY WAIVES THE RIGHT TO A JURY TRIAL IN CONNECTION WITH ANY LEGAL PROCEEDING RELATING TO THIS AGREEMENT OR THE ENFORCEMENT OF ANY PROVISION OF THIS AGREEMENT.

7.12 Delays or Omissions No delay or omission to exercise any right, power or remedy accruing to the Company or to any Buyer, upon any breach or default of any party hereto under this Agreement, shall impair any such right, power or remedy of the Company or any Buyer nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of any similar breach of default thereafter occurring; nor shall any waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of the Company or any Buyer of any breach of default under this Agreement, or any waiver on the part of the Company or any Buyer of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement, or by law or otherwise afforded to the Company or any Buyer, shall be cumulative and not alternative.
