A. Investment Representations and Legend Requirements. The Purchaser hereby makes the investment representations listed on Exhibit A to the Company as of the date of this Agreement and as of the date of the Closing, and agrees that such representations are incorporated into this Agreement by this reference, such that the Company may rely on them in issuing the Shares. The Purchaser understands and agrees that the Company shall cause the legends set forth below, or substantially equivalent legends, to be placed upon any certificate(s) evidencing ownership of the Shares, together with any other legends that may be required by the Company or by applicable state or federal securities laws:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE “ACT”) AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT.

B. Stop-Transfer Notices. The Purchaser agrees that to ensure compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to the same effect in its own records.

C. Refusal to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.

The Purchaser further agrees, if so requested by the Company or any representative of its underwriters, to enter into such underwriter’s standard form of “lockup” or “market standoff” agreement in a form satisfactory to the Company and such underwriter. The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of any such restriction period.

E. Restrictions on Shares.

Exhibit A

INVESTMENT REPRESENTATION STATEMENT

In connection with the purchase of the above-listed shares, Purchaser represents to the Company as follows:

1. The Company may rely on these representations. Purchaser understands that the Company’s sale of the shares to Purchaser has not been registered under the Securities Act of 1933, as amended (the “Securities Act”), because the Company believes, relying in part on its representations in this document, that an exemption from such registration requirement is available for such sale. Purchaser understands that the availability of this exemption depends upon the representations it is making to the Company in this document being true and correct.

2. Purchasing for investment. Purchaser is purchasing the shares solely for investment purposes, and not for further distribution. Its entire legal and beneficial ownership interest in the shares is being purchased and shall be held solely for its account. Purchaser is not a party to, and do not presently intend to enter into, any contract or other arrangement with any other person or entity involving the resale, transfer, grant of participation with respect to or other distribution of any of the shares. Purchaser’s investment intent is not limited to its present intention to hold the shares for the minimum capital gains period specified under any applicable tax law, for a deferred sale, for a specified increase or decrease in the market price of the shares, or for any other fixed period in the future.

3. Purchaser can protect its own interests. Purchaser can properly evaluate the merits and risks of an investment in the shares and can protect its own interests in this regard, whether by reason of its own business and financial expertise, the business and financial expertise of certain professional advisors unaffiliated with the Company with whom it may have consulted, or its preexisting business or personal relationship with the Company or any of its officers, directors or controlling persons.

4. Purchaser is informed about the Company. Purchaser is sufficiently aware of the Company’s business affairs and financial condition to reach an informed and knowledgeable decision to acquire the shares. Purchaser has had opportunity to discuss the plans, operations and financial condition of the Company with its officers, directors or controlling persons, and have received all information it deems appropriate for assessing the risk of an investment in the shares.

5. Purchaser recognizes its economic risk. Purchaser realizes that the purchase of the shares involves a high degree of risk, and that the Company’s future prospects are uncertain. Purchaser is able to hold the shares indefinitely if required, and is able to bear the loss of my entire investment in the shares.

6. Purchaser knows that the shares are restricted securities. Purchaser understands that the shares are “restricted securities” in that the Company’s sale of the shares has not been registered under the Securities Act in reliance upon an exemption for non-public offerings. In this regard, Purchaser also understands and agrees that:

A. It must hold the shares indefinitely, unless any subsequent proposed resale is registered under the Securities Act, or unless an exemption from registration is otherwise available (such as Rule 144);

B. the Company is under no obligation to register any subsequent proposed resale of the shares; and

C. the certificate evidencing the shares will be imprinted with a legend which prohibits the transfer of the shares unless such transfer is registered or such registration is not required in the opinion of counsel for the Company.

7. Purchaser is familiar with Rule 144. Purchaser is familiar with Rule 144 adopted under the Securities Act, which in some circumstances permits limited public resales of “restricted securities” like the shares acquired from an issuer in a non-public offering. Purchaser understands that its ability to sell the shares under Rule 144 in the future is uncertain, and may depend upon, among other things: (i) the availability of certain current public information about the Company; (ii) the resale occurring more than a specified period after this purchase and full payment (within the meaning of Rule 144) for the shares; and (iii) if Purchaser is an affiliate of the Company (A) the sale being made in an unsolicited “broker’s transaction”, transactions directly with a market maker or riskless principal transactions, as those terms are defined under the Securities Exchange Act of 1934, as amended, (B) the amount of shares being sold during any three-month period not exceeding the specified limitations stated in Rule 144, and (C) timely filing of a notice of proposed sale on Form 144, if applicable.

8. Purchaser knows that Rule 144 may never be available. Purchaser understands that the requirements of Rule 144 may never be met, and that the shares may never be saleable under the rule. Purchaser understands that at the time it wishes to sell the shares, there may be no public market for the Company’s stock upon which to make such a sale, or the current public information requirements of Rule 144 may not be satisfied, either of which may preclude Purchaser from selling the shares under Rule 144 even if the relevant holding period had been satisfied.

9. Purchaser understands that it is subject to further restrictions on resale. Purchaser understands that in the event Rule 144 is not available, any future proposed sale of any of the shares will not be possible without prior registration under the Securities Act, compliance with some other registration exemption (which may or may not be available), or each of the following: (i) its written notice to the Company containing detailed information regarding the proposed sale, (ii) Purchaser providing an opinion of my counsel to the effect that such sale will not require registration, and (iii) the Company notifying Purchaser in writing that its counsel concurs in such opinion. Purchaser understands that neither the Company nor its counsel is obligated to provide it with any such opinion. Purchaser understands that although Rule 144 is not exclusive, the Staff of the SEC has stated that persons proposing to sell private placement securities other than in a registered offering or pursuant to Rule 144 will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk.

10. Purchaser understands that it may have tax liability due to the uncertain value of the shares. Purchaser understands that the board of directors believes its valuation of the shares represents a fair appraisal of their worth, but that it remains possible that, with the benefit of hindsight, the Internal Revenue Service may successfully assert that the value of the shares on the date of the purchase is substantially greater than the Board’s appraisal. Purchaser understands that any additional value ascribed to the shares by such an IRS determination will constitute ordinary income to Purchaser as of the purchase date, and that any additional taxes and interest due as a result will be Purchaser’s sole responsibility payable only by Purchaser, and that the Company need not and will not reimburse Purchaser for that tax liability.

11. Residence. The address of the Purchaser’s principal residence is set forth on the signature page below.

By signing below, Purchaser acknowledges its agreement with each of the statements contained in this Investment Representation Statement as of the date first set forth above, and its intent for the Company to rely on such statements in issuing the shares.
