Section 2. Representations and Warranties of Company. Company hereby represents and warrants to the Purchasers that the Company has the requisite corporate or other power and authority to enter into and perform its obligations under this Agreement, and this Agreement has been duly authorized, executed and delivered by Company, enforceable in accordance with its terms.

Section 3. Representations of Purchasers. Each of the Purchasers hereby represent and warrant to Company as follows:

(a) Capacity. Purchaser, having full legal capacity to do so, has duly executed this Agreement and this Agreement constitutes the legal, valid and binding obligation of Purchaser enforceable against Purchaser in accordance with its terms.

(b) Purchase for Own Account. The Securities to be purchased hereunder will be acquired for the Purchaser’s own account, for investment purposes and not as a nominee or agent, and not with a view to the public resale or distribution of any part thereof within the meaning of the Securities Act of 1933, as amended (the “Securities Act”), and Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same in a manner that would cause the purchase of the Securities hereunder to become subject to the registration requirements of the Securities Act or similar requirements under any other applicable law. The Purchaser does not have any contract, undertaking, agreement, or arrangement with any person to sell, transfer, or grant participations to such person or any third party with respect to the Securities.

(c) Disclosure of Information. Purchaser has conducted its own investigation of Company to its own satisfaction and has received or has had full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to the Securities to be purchased under this Agreement. In addition, Purchaser has had an opportunity to ask questions and receive answers from Company regarding the terms and conditions of the offering of the Securities and to obtain additional information Purchaser believes to be necessary or appropriate to verify any information furnished to Purchaser or to which Purchaser had access.

(d) Restricted Securities. Purchaser acknowledges and understands that: (a) the offering and sale of the Purchased Shares will not be registered under the Securities Act; (b) the Securities will be “restricted securities” under the Securities Act because they are being acquired from Company in a transaction not involving a public offering, and that under the Securities Act such securities may not be offered, sold or transferred unless they are duly registered or such offer or sale is made in accordance with an exemption from registration; (c) Company is under no obligation to register any of the securities sold hereunder by the terms of this Agreement; and (d) if an exemption from registration or qualification is available, it may be conditioned upon various requirements including the time and manner of sale, the holding period and requirements relating to Company which may be outside Purchaser’s control and which Company may not be able to satisfy.
