2. Representations and Warranties. The Holder hereby represents and warrants to the Company, and the Company hereby represents and warrants to the Holder, that (i) it has the full right, power and authority to enter into this Agreement and to perform its obligations hereunder and the Warrants as amended by this Agreement, and (ii) the execution of this Agreement by the individual whose signature is set forth at the end of this Agreement on behalf of such party, and the delivery of this Agreement by such party, have been duly authorized by all necessary action on the part of such party; and (iii) this Agreement has been executed and delivered by such party and constitutes the legal, valid and binding obligation of such party, enforceable against such party in accordance with its terms, except as may be limited by any applicable bankruptcy, insolvency, reorganization, moratorium, or similar laws and equitable principles related to or affecting creditors' rights generally or the effect of general principles of equity.

2A. Holding Period. The Holder represents that it has held the Warrants continuously for the prior 12 months and the purchase price for the Warrants has been fully paid for such 12-month period. For the purposes of Rule 144 promulgated under the U.S Securities Act of 1933, as amended (the “Securities Act”), the Company acknowledges that the holding period of the Shares may be tacked onto the holding period of the Warrants and the Company agrees not to take a position to the contrary. In addition, the parties intend for the transactions contemplated hereby to meet the requirements of Section 3(a)(9) of the Securities Act.  In connection with the foregoing, if required by the transfer agent to effect removal of a restrictive legend on the certificates or a notation on the book-entry evidencing the Shares to be sold under Rule 144, the Company shall cause its counsel to issue a legal opinion to the transfer agent to the effect that the holding period of the Shares may be tacked onto the holding period of the Warrants and that the transfer of Shares pursuant to Rule 144 does not require registration of such transferred Shares under the Securities Act, provided that the Holder executes and delivers appropriate representations and documentation the Company’s counsel may reasonably request for such purpose.

2B. Post-Recapitalization Percentage Ownership. Immediately after the issuance of the Shares, the Shares shall consist of ______% of the Company’s capital stock on a fully diluted basis. At the time of the issuance of the Shares to the Holder, the Company will not have outstanding any debt or securities that give any rights of anti-dilution or similar adjustments.

In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

5. Choice of Law; Forum. This Agreement shall be construed and enforced in accordance with the laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York.
