C.	Investment Representations.

(i) Each of the Purchasers is acquiring the Founding Director Warrants and, upon exercise thereof, the Common Stock issuable upon such exercise (collectively, the “Securities”) for his own account, for investment only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.

(ii) Each Purchaser is an “accredited investor” as defined in Rule 501(a)(3) of Regulation D.

(iii) Each Purchaser understands that the Securities are being offered and sold to him in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and Purchaser’s compliance with, the representations, warranties and agreements of Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of Purchaser to acquire such securities.

(iv) Each Purchaser initiated discussions with the Company relating to the purchase and sale of the Securities contemplated by this Agreement on an unsolicited basis prior to the date of this Agreement. The Purchasers did not initiate such discussions, nor did Purchasers decide to enter into this Agreement, as a result of any general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act of 1933, as amended (the “Securities Act”), including the filing of the Registration Statement.

(v) Each Purchaser has been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by Purchaser. Each Purchaser has been afforded the opportunity to ask questions of the other executive officers and directors of the Company. Each Purchaser understands that his investment in the Securities involves a high degree of risk. Each Purchaser has sought such accounting, legal and tax advice as he has considered necessary to make an informed investment decision with respect to his acquisition of the Securities. Each Purchaser has received and reviewed a copy of the Registration Statement, including without limitation, the language therein under the caption “Risk Factors,” and signed the Registration Statement signature page in his capacity as an officer or director (or both) of the Company, as the case may be.

(vi) Each Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

(vii) Each Purchaser understands that: (a) the Securities have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder or (B) sold in reliance on an exemption therefrom; and (b) except as specifically set forth in the Registration Rights Agreement, neither the Company nor any other person is under any obligation to register such securities under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder. In this regard, each Purchaser represents that he is familiar with Rule 144 adopted pursuant to the Securities Act, and understands the resale limitations imposed thereby and by the Securities Act. Each Purchaser is able to bear the economic risk of its investment in the Securities for an indefinite period of time.

Each Purchaser can afford a complete loss of his investment in the Securities.

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

(b) (i) The Purchaser 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 (ii) if reasonably requested by the Company, the Purchaser shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of such Securities under the Securities Act. Notwithstanding the foregoing, each Purchaser also understands and acknowledges that the transfer or exercise of the Founding Director Warrants is subject to the specific conditions to such transfer or exercise as outlined herein, as to which each Purchaser specifically assents by his execution hereof.

D. No Group. By virtue of the Purchasers purchasing the Founding Director Warrants under this Agreement, such participation shall not be construed so as to make any of the Purchasers part of, or a participant in, a “group” as defined in Rule 13d-5 of the Exchange Act with respect to any securities of the Company.

E.	Rescission Right Waiver and Indemnification.

(i) Each of the Purchasers understands and acknowledges that an exemption from the registration requirements of the Securities Act requires that there be no general solicitation of purchasers of the Founding Director Warrants. In this regard, if the Offering of the Units were deemed to be a general solicitation with respect to the Founding Director Warrants, the offer and sale of such Founding Director Warrants may not be exempt from registration and, if not, the Purchasers may have a right to rescind their purchases of the Founding Director Warrants. In order to facilitate the completion of the Offering and in order to protect the Company, its stockholders and the Trust Account from claims that may adversely affect the Company or the interests of its stockholders, each of the Purchasers hereby agrees to waive, to the maximum extent permitted by

applicable law, any claims, right to xxx or rights in law or arbitration, as the case may be, to seek rescission of his purchase of the Founding Director Warrants. Each of the Purchasers acknowledges and agrees that this waiver is being made in order to induce the Company to sell the Founding Director Warrants to the Purchasers. Each Purchaser agrees that the foregoing waiver of rescission rights shall apply to any and all known or unknown actions, causes of action, suits, claims, or proceedings (collectively, “Claims”) and related losses, costs, penalties, fees, liabilities and damages, whether compensatory, consequential or exemplary, and expenses in connection therewith (collectively, “Losses and Expenses”) including reasonable attorneys’ and expert witness fees and disbursements and all other expenses reasonably incurred in investigating, preparing or defending against any Claims, whether pending or threatened, in connection with any present or future actual or asserted right to rescind the purchase of the Founding Director Warrants hereunder or relating to the purchase of the Founding Director Warrants and the transactions contemplated hereby.

(ii) Each Purchaser agrees not to seek recourse against the Trust Account for any reason whatsoever in connection with his purchase of the Founding Director Warrants or any Claim that may arise now or in the future.

(iii) Each Purchaser (collectively, “Indemnitors”) agrees to severally indemnify and hold harmless the Company, the Representative, the underwriters of the Offering and the Trust Account against any and all Losses and Expenses whatsoever to which the Company, the Representatives and the Trust Account may become subject as a result of the purchase of the Founding Director Warrants by the Purchasers or a Purchaser, including but not limited to any Claim by any Purchaser of the Founding Director Warrants, but only to the extent necessary to ensure that such Losses and Expenses do not reduce the amount in the Trust Account. To the extent that the foregoing several indemnification by the Indemnitors may be unenforceable for any reason, each of the Indemnitors agree to make the maximum contribution permissible by applicable law to the payment and satisfaction of any Losses and Expenses relating to Claims that may or will otherwise reduce the amount in the Trust Account. Any Losses and Expenses indemnified hereunder by the Indemnitors will be paid equally by them except to the extent that such Claims are brought by either of the Indemnitors, in which case the foregoing indemnity obligation shall only be that of the person making the Claim, it being the understanding and agreement of the Indemnitors that each of them shall be held harmless by the other as to any Claims, Losses and Expenses.

(iv) The Purchasers acknowledge and agree that the stockholders of the Company, including those who purchase the Units in the Offering, are and shall be third-party beneficiaries of the foregoing provisions of Section 5G of this Agreement.

(v) Each Purchaser agrees that to the extent any waiver of rights under this Section 4. E is ineffective as a matter of law, each Purchaser has offered such waiver for the benefit of the Company as an equitable right that shall survive any statutory disqualification or bar that applies to a legal right.

Ladies and Gentlemen:

Each of the undersigned appoints Xxxxxx Xxxxxxxxx LLP (the “Escrow Agent”) to act as Escrow Agent in connection with consummation of the transactions contemplated by the Warrant Purchase Agreement for the sole purpose of holding consideration in the amount of $550,000.00 (referred to herein as the “Escrowed Funds”) to be paid by the Purchasers until such time as Escrow Agent receives a release certificate, in the form attached hereto as Exhibit A, (the “Release”) executed by the Company and the Purchasers instructing the Escrow Agent to release such funds in accordance with the written instructions set forth in the Release, which instructions shall set forth fully the account information needed for Escrow Agent to forward the Escrowed Funds by means of electronic funds transfer.

In the event that the Escrow Agent has not received the Release by _____________, 2006, Escrow Agent shall return the Escrowed Funds, without any interest accruing thereon, to Purchasers in accordance with the Purchasers’ written instructions. The Escrowed Funds shall be held in a non-interest bearing account.

Upon the release and delivery by the Escrow Agent of the Escrowed Funds deposited herewith to the party entitled to receive the same in accordance with the instructions set forth above, the Escrow Agent’s appointment, duties and obligations hereunder shall be deemed completed and the Escrow Agent shall be discharged. Upon discharge of the Escrow Agent, this Escrow Agreement shall be terminated except for the provisions of the next succeeding paragraph which shall survive the termination of this Agreement.

Each of the undersigned hereby agrees to indemnify and hold harmless the Escrow Agent against any and all losses, claims, damages, liabilities and expenses, including reasonable costs of investigation and counsel fees and disbursements which may be imposed upon or incurred by the Escrow Agent in connection with the performance of its duties hereunder, including any litigation arising from, or involving the subject matter of, the items deposited in the escrow with the Escrow Agent under this Agreement, except to the extent caused by the gross negligence or willful misconduct of the Escrow Agent.
