the surrender of the Warrant, together with a duly executed copy of the Notice of Exercise attached hereto, to the Company at its principal office (or at such other place as the Company shall notify the Holder in writing); and

the payment to the Company of an amount equal to the aggregate Exercise Price for the number of Shares being purchased.

At such time, the person or persons in whose name or names any certificate for the Shares shall be issuable upon such exercise as provided in Section 3(c) below shall be deemed to have become the holder or holders of record of the Shares represented by such certificate.

The Company is duly qualified to transact business and is in good standing in each jurisdiction in which the failure to so qualify would have a material adverse effect on its business or properties.

Authorization.

The Company has taken all corporate action required to make all the obligations of the Company reflected in the provisions of this Warrant the valid and enforceable obligations they purport to be. The issuance of this Warrant will not be subject to preemptive rights of any stockholders of the Company. The Company has authorized sufficient shares of Exercise Stock to allow for the exercise of this Warrant.

Compliance with Other Instruments. The authorization, execution and delivery of the Warrant will not constitute or result in a material default or violation of any law or regulation applicable to the Company or any material term or provision of the Certificate of Incorporation or bylaws, or any material agreement or instrument by which it is bound or to which its properties or assets are subject.

Valid Issuance of Shares. The Shares, when issued, sold, and delivered in accordance with the terms of this Warrant for the consideration expressed therein, will be duly and validly issued, fully paid and nonassessable and, based in part upon the representations and warranties of the Holders in this Warrant, will be issued in compliance with all applicable federal and state securities laws.

Representations and Warranties of the Holder. In connection with the transactions provided for herein, the Holder hereby represents and warrants to the Company that:

Authorization. Holder represents that it has full power and authority to enter into this Warrant. This Warrant constitutes the Holder’s valid and legally binding obligation, enforceable in accordance with its terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization, or similar laws relating to or affecting the enforcement of creditors’ rights and (ii) laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

Purchase Entirely for Own Account. The Holder acknowledges that this Warrant is entered into by the Holder in reliance upon such Holder’s representation to the Company that the Warrant and the Shares, and any shares of the Company’s capital stock issuable upon conversion of the Shares (collectively, the “Securities”) will be acquired for investment for the Holder’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Holder has no present intention of selling, granting any participation in or otherwise distributing the same. By acknowledging this Warrant, the Holder further represents that the Holder does not have any contract, undertaking, agreement, or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to the Securities.

Disclosure of Information. The Holder acknowledges that it has received all the information it considers necessary or appropriate for deciding whether to acquire the Securities. The Holder further represents that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Securities.

Investment Experience. The Holder is an investor in securities of companies in the development stage and acknowledges that it is able to fend for itself, can bear the economic risk of its investment, and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Securities. If other than an individual, the Holder also represents it has not been organized solely for the purpose of acquiring the Securities.

Accredited Investor and Other Matters.

Withholding Taxes. Holder acknowledges that dividends with respect to the Shares may be subject to applicable withholding requirements.

Restricted Securities. The Holder understands that the Securities are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such securities may be resold without registration under the Act, only in certain limited circumstances. In this connection, Holder represents that it is familiar with Rule 144, as presently in effect, as promulgated by the SEC under the Act (“Rule 144”), and understands the resale limitations imposed thereby and by the Act.

Further Limitations on Disposition. Without in any way limiting the representations set forth above, the Holder further agrees not to make any disposition of all or any portion of the Shares unless and until the transferee has agreed in writing for the benefit of the Company to be bound by the terms of this Warrant, including, without limitation, this Section 6, Section 25, and:

there is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

the Holder shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, the Holder shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such shares under the Act.
