2. Representations and Warranties. In order to induce the Company to accept this subscription, the Subscriber hereby represents and warrants to, and covenants with, the Company as follows:

(a) The Subscriber been given access to full and complete information regarding the Company and has utilized such access to the Subscriber’s satisfaction for the purpose of obtaining such information regarding the Company as the Subscriber has reasonably requested; and, particularly, the Subscriber has been given reasonable opportunity to ask questions of, and receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities and to obtain any additional information, to the extent reasonably available;

(b) The Subscriber acknowledges and agrees that no representations or warranties have been made to the Subscriber by the Company, any selling agent of the Company, or any agent, employee, or affiliate of the Company or such selling agent.

(c) The Subscriber believes that an investment in the securities is suitable for the Subscriber based upon the Subscriber investment objectives and financial needs. The Subscriber (i) has adequate means for providing for the Subscriber’s current financial needs and personal contingencies; (ii) has no need for liquidity in this investment; (iii) at the present time, can afford a complete loss of such investment; and (iv) does not have an overall commitment to investments which are not readily marketable that is disproportionate to the Subscriber’s net worth, and the Subscriber’s investment in the Securities will not cause such overall commitment to become excessive.

(d) The Subscriber, in reaching a decision to subscribe, has such knowledge and experience in financial and business matters that the Subscriber is capable of reading and interpreting financial statements and evaluating the merits and risk of an investment in the Securities and has the net worth to undertake such risks.

(e) The Subscriber was not offered or sold the Securities, directly or indirectly, by means of any form of general advertising or general solicitation, including, but not limited to, the following: (1) any advertisement, article, notice or other communication published in any newspaper, magazine, or similar medium of or broadcast over television or radio; or (2) to the knowledge of the undersigned, any seminar or meeting whose attendees had been invited by any general solicitation or general advertising.

(f) The Subscriber has obtained, to the extent the Subscriber deems necessary, the Subscriber’s own personal professional advice with respect to the risks inherent in the investment in the securities, and the suitability of an investment in the Securities in light of the Subscriber’s financial condition and investment needs;

(g) The information contained in this agreement is true, complete and correct in all material respects as of the date hereof; the Subscriber understands that the Company’s determination that the exemption from the registration provisions of the Securities Act of 1933, as amended (the “Act”), which is based upon non-public offerings and applicable to the offer and sale of the Securities, is based, in part, upon the representations, warranties, and agreements made by the Subscriber herein; and the Subscriber consents to the disclosure of any such information, and any other information furnished to the Company, to any governmental authority, self-regulatory organization, or, to the extent required by law, to any other person.

(h) The Subscriber realizes that (i) the purchase of the Securities is a long-term investment; (ii) the purchaser of the Securities must bear the economic risk of investment for an indefinite period of time because the Securities have not been registered under the Securities Act of 1933 or under the securities laws of any state and, therefore, the Securities cannot be resold unless they are subsequently registered under said laws or exemptions from such registrations are available; (iii) there is presently no public market for the Securities and the Subscriber may be unable to liquidate the Subscriber’s investment in the event of an emergency, or pledge the Securities as collateral for a loan; and (iv) the transferability

of the Securities is restricted and (A) requires conformity with the restrictions contained in paragraph 2 below and (B) legends will be placed on the certificate(s) representing the Securities referring to the applicable restrictions on transferability; and

(i) The Subscriber certifies, under penalties of perjury, that the Subscriber is NOT subject to the backup withholding provisions of Section 3406(a)(i)(C) of the Internal Revenue Code.

(j) Stop transfer instructions will be placed with the transfer agent for the Securities, and a legend may be placed on any certificate representing the Securities substantially to the following effect:

THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), IN RELIANCE UPON THE EXEMPTIONS FROM REGISTRATION PROVIDED IN THE ACT AND REGULATION D UNDER THE ACT. AS SUCH, THE PURCHASE OF THIS SECURITY WAS NECESSARILY WITH THE INTENT OF INVESTMENT AND NOT WITH A VIEW FOR DISTRIBUTION. THEREFORE, ANY SUBSEQUENT TRANSFER OF THIS SECURITY OR ANY INTEREST THEREIN WILL BE UNLAWFUL UNLESS IT IS REGISTERED UNDER THE ACT OR UNLESS AN EXEMPTION FROM REGISTRATION IS AVAILABLE. FURTHERMORE, IT IS UNLAWFUL TO CONSUMMATE A SALE OR TRANSFER OF THIS SECURITY OR ANY INTEREST THEREIN, WITHOUT THE OPINION OF COUNSEL ACCEPTABLE TO THE COMPANY THAT THE PROPOSED TRANSFER OR SALE DOES NOT AFFECT THE EXEMPTIONS RELIED UPON BY THE COMPANY IN ORIGINALLY DISTRIBUTING THE SECURITY AND THAT REGISTRATION IS NOT REQUIRED.

3. Restricted Nature of the Securities. The Subscriber has been advised and understands that (a) the Securities have not been registered under the Securities Act of 1933 or applicable state securities laws and that the securities are being offered and sold pursuant to exemptions from such laws; (b) the offering may not have been filed with or reviewed by certain state securities administrators because of the limited nature of the offering; (c) the Company is under no obligation to register the Securities under the Act or any state securities laws, or to take any action to make any exemption from any such registration provisions available. The Subscriber represents and warrants that the Securities are being purchased for the Subscriber’s own account and for investment purposes only, and without the intention of reselling or redistributing the same; the Subscriber has made no agreement with others regarding any of the Securities; and the Subscriber’s financial condition is such that it is not likely that it will be necessary to dispose of any of such Securities in the foreseeable future. The Subscriber is aware that, in the view of the Securities and Exchange Commission, a purchase of such securities with an intent to resell by reason of any foreseeable specific contingency or anticipated change in market value, or any change in the condition of the Company, or in connection with a contemplated liquidation settlement of any loan obtained for the acquisition of such securities and for which such securities were pledged, would represent an intent inconsistent with the representations set forth above. The Subscriber further represents and agrees that if, contrary to the foregoing intentions, the Subscriber should later desire to dispose of or transfer any of such securities in any manner, the Subscriber shall not do so unless and until (i) said Securities shall have first been registered under the Act and all applicable securities laws; or (ii) the Subscriber shall have first delivered to the Company a written notice declaring such holder’s intention to effect such transfer and describe in sufficient detail the manner and circumstances of the proposed transfer, which notice shall be accompanied either by a written opinion of legal counsel who shall be reasonably satisfactory to the Company, which opinion shall be addressed to the Company and reasonably satisfactory in form and substance to the Company’s counsel, to the effect that the proposed sale or

transfer is exempt from the registration provisions of the Act and all applicable state securities laws, or by a “no action” letter from the Securities and Exchange Commission to the effect that the transfer of the Securities without registration will not result in recommendation by the staff of the Commission that action be taken with respect thereto.

4. Residence. The Subscriber represents and warrants that the Subscriber is a bona fide resident of, is domiciled in and received the offer and made the decision to invest in the Securities in the state set forth on the signature page hereof, and the Securities are being purchased by the Subscriber in the Subscriber’s name solely for the Subscriber’s own beneficial interest and not as nominee for, or on behalf of, or for the beneficial interest of, or with the intention to transfer to, any other person, trust or organization, except as specifically set forth in paragraph 15 of this Subscription Agreement and Letter of Investment Intent.
