REPRESENTATIONS AND WARRANTIES OF THE BUYERS

Section 3.1 Power and Authority; Enforceability. This Agreement constitutes the legal, valid, and binding obligation of the Buyers, enforceable against each Buyer in accordance with its terms. Each Buyer has full power and authority to execute and deliver this Agreement and to perform its obligations hereunder. Each Buyer has taken all actions necessary to authorize the execution and delivery of this Agreement, the performance of its obligations hereunder and the consummation of the transactions contemplated hereby. This Agreement has been duly authorized, executed and delivered by, and is enforceable against, each Buyer, subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to general equitable principles (whether considered in a proceeding in equity or law).

Section 3.2 No Violation; Necessary Approvals. Neither the execution and delivery of this Agreement by the Buyers, nor the consummation or performance by the Buyers of any of transactions contemplated hereby, will: (a) with or without notice or lapse of time, constitute, create or result in a breach or violation of, default under, loss of benefit or right under or acceleration of performance of any obligation required under any (i) law (statutory, common or otherwise), constitution, ordinance, rule, regulation, executive order or other similar authority (“Law”) enacted, adopted, promulgated or applied by any legislature, agency, bureau, branch, department, division, commission, court, tribunal or other similar recognized organization or body of any federal, state, county, municipal, local or foreign government or other similar recognized organization or body exercising similar powers or authority (a “Governmental Body”), (ii) order, ruling, decision, award, judgment, injunction or other similar determination or finding by, before or under the supervision of any Governmental Body or arbitrator (an “Order”), (iii) contract, agreement, arrangement, commitment, instrument, document or similar understanding (whether written or oral), including a lease, sublease and rights thereunder (“Contract”) or permit, license, certificate, waiver, notice and similar authorization (“Permit”) to

3

which, in the case of (i), (ii) or (iii), any Buyer is a party or by which any Buyer is bound or any of its assets are subject; (b) require any Consent under any Contract or organizational document to which any Buyer is a party or by which it is bound or any of its assets are subject; or (c) require any Permit under any Law or Order other than (i) required filings, if any, with the Securities and Exchange Commission (“SEC”) and (ii) notifications or other filings with state or federal regulatory agencies after the Closing that are necessary or convenient and do not require approval of the agency as a condition to the validity of the transactions contemplated hereunder.

Section 3.3 Investment Representations.

(a) Each Buyer has received, has thoroughly read, is familiar with and understands the contents of this Agreement.

(b) Each Buyer hereby acknowledges that an investment in the Shares involves certain significant risks. Each Buyer acknowledges that there is a substantial risk that it will lose all or a portion of its investment and should be financially capable of bearing the risk of such investment for an indefinite period of time. Each Buyer has no need for liquidity in its investment in the Shares for the foreseeable future and is able to bear the risk of that investment for an indefinite period. Each Buyer understands that there presently is no public market for the Shares and none is anticipated to develop in the foreseeable future. Each Buyer’s present financial condition is such that it is under no present or contemplated future need to dispose of any portion of the Shares subscribed for hereby to satisfy any existing or contemplated undertaking, need or indebtedness. Each Buyer’s overall commitment to investments which are not readily marketable is not disproportionate to its net worth and the investment in the Company will not cause such overall commitment to become excessive.

(c) Each Buyer acknowledges that the Shares have not been registered under the Securities Act, or any state securities act, and are being sold on the basis of exemptions from registration under the Securities Act and applicable state securities acts, except those state securities acts that require registration of the Shares thereunder. Reliance on such exemptions, where applicable, is predicated in part on the accuracy of the Buyers’ representations and warranties set forth herein. Each Buyer acknowledges and hereby agrees that the Shares will not be transferable under any circumstances unless such Buyer either registers the Shares in accordance with federal and state securities laws or finds and complies with an exemption under such laws. Accordingly, each Buyer hereby acknowledges that there can be no assurance that it will be able to liquidate its investment in the Company. Each Buyer understands that the Company is under no obligation to register the Shares under the Securities Act or to comply with any applicable exemption under the Securities Act on behalf of such Buyer with respect to any resale of the Shares and that such Buyer will not be able to avail itself of the provisions of Rule 144 promulgated under the Securities Act with respect to the resale of the Shares until the Shares have been beneficially owned by such Buyer for a period of at least one (1) year from date of purchase. Each Buyer further understands that any certificates evidencing the Shares will bear a legend referring to the foregoing transfer restrictions.

(d) In evaluating the merits and risks of an investment in the Company, each Buyer has had the opportunity to seek the advice of its legal and financial advisors, has availed

4

itself of that right to the extent deemed appropriate, and has not relied on the advice of the Company or the Company’s legal and financial counsel.

(e) Subject to the provisions of Section 3.4(i) below, the Shares are being acquired solely for each Buyer’s own account, for investment purposes only, and are not being purchased with a view to or for the resale, distribution, subdivision or fractionalization thereof; and each Buyer has no present plans to enter into any contract, undertaking, agreement or arrangement for such resale, distribution, subdivision or fractionalization. Each Buyer is not taking and will not take or cause to be taken any action that would cause such Buyer to be deemed an “underwriter” within the meaning of Section 2(11) of the Securities Act.

(f) There are substantial risk factors pertaining to an investment in the Company. Each Buyer acknowledges that it has read the information set forth above regarding certain of such risks and is familiar with the nature and scope of all such risks, including, without limitation, risks arising from the fact that the Company is an entity with limited operating history and financial resources; and each Buyer is fully able to bear the economic risks of such investment for an indefinite period, and can afford a complete loss thereof.

(g) Each Buyer has been given the opportunity to (i) ask questions of and receive answers from the Company and its designated representatives concerning the terms and conditions of the offering, the Company and the business and financial condition of the Company and (ii) obtain any additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to assist such Buyer in evaluating the advisability of the purchase of the Shares and an investment in the Company. Each Buyer further represents and warrants that, prior to signing this Agreement, it has asked such questions, received such answers and obtained such information as it has deemed necessary or advisable to evaluate the merits and risks of the purchase of the Shares and an investment in the Company. Each Buyer is not relying on any oral representation made by any person as to the Company or its operations, financial condition or prospects.

(h) Each Buyer understands that no federal, state or other governmental authority has made any recommendation, findings or determination relating to the merits of an investment in the Company.

(i) Each Buyer is purchasing the Shares on its own behalf and on behalf of future directors, officers and investors in the Company. Accordingly, such Buyer may sell all or a portion of the Shares to such future directors, officers and investors in the Company pursuant to one or more private placement transactions in reliance upon an exemption from registration afforded by the Securities Act.
