Each outstanding share of Common Stock is duly authorized, validly issued, fully paid and non-assessable, and has not been issued and is not owned or held in violation of any preemptive rights of stockholders.

Wheaton hereby represents and warrants to the Company as follows: 4.1 Wheaton is a bona fide resident of the state set forth in Section 7.3 of this Agreement and is legally competent to execute this Agreement. 4.2 Wheaton has received, read carefully and is familiar with this Agreement. Respecting the Company, Wheaton is familiar with the Company's business and financial condition and any other matters relating to the transactions contemplated hereby; Wheaton has received all materials which have been requested by him, has had a reasonable opportunity to ask questions of the Company and its representatives, and the Company has answered all inquiries that Wheaton has put to it. Wheaton has taken all the steps necessary to evaluate the merits and risks of the transactions effected hereby. 4.3 Wheaton has been advised by the Company to consider retaining legal counsel in connection with the preparation and the execution of this Agreement. 4.4 Wheaton represents that he is an "accredited investor" as such term is defined in Rule 501 of the Rules and Regulations promulgated under the Securities Act of 1933, as amended (the "Securities Act"). 4.5 Wheaton has such knowledge and experience in finance, securities, investments and other business matters so as to be able to evaluate the merits and risks of his investment in the Company. 4.6 Wheaton has adequate means of providing for his current and foreseeable future needs and has no need for liquidity of his investment in the Company. Wheaton recognizes and is fully cognizant of the fact that his investment in the Company involves a high degree of risk, and Wheaton represents that he can afford to bear such risk, including, without limitation, the risk of losing the entire investment. 4.7 Wheaton has been advised by the Company that (i) the Series A Shares purchased hereby and the shares of Common Stock into which the Series A Shares may be converted (collectively, the "Securities") have not been registered under the Securities Act, and that the Securities will be issued on the basis of the statutory exemption provided by Section 4(2) of the Securities Act or Regulation D promulgated thereunder, or both, relating to transactions by an issuer not involving any public offering, and under similar exemptions under applicable state securities laws; (ii) none of the Securities have been registered or qualified with any federal or state agency or self-regulatory organization, and (iii) the Company's reliance on exemptions from federal and state registration or qualification requirements is based in part upon the representations made by Wheaton contained in this Agreement. 4.8 Wheaton has been advised by the Company of, and/or he is otherwise familiar with, the nature of the limitations on the transfer of the Securities imposed by the Securities Act and the Rules and Regulations promulgated thereunder. In particular, Wheaton agrees that no sale, assignment or transfer of any of the Securities shall be valid or effective (and agrees to not so sell, assign or transfer any of the Securities), and the Company shall not be required to give any effect to such a sale, assignment or transfer, unless the sale, assignment or transfer is (i) registered under the Securities Act, it being understood that none of the Securities are currently registered for sale; or (ii) made in accordance with all the requirements and limitations of Rule 144 under the Securities Act. Wheaton acknowledges that the Securities shall be subject to a stop transfer order and that the certificate or certificates evidencing the Securities shall bear the following legend (and such other legends as may be required by state blue sky laws): THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND MAY NOT BE OFFERED, SOLD, PLEDGED, HYPOTHECATED, ASSIGNED OR TRANSFERRED EXCEPT (1) A REGISTRATION STATEMENT UNDER THE ACT WHICH HAS BECOME EFFECTIVE AND IS CURRENT WITH RESPECT TO THESE SECURITIES, OR (2) PURSUANT TO A SPECIFIC EXEMPTION FROM REGISTRATION UNDER THE ACT BUT ONLY UPON A HOLDER HEREOF FIRST HAVING OBTAINED THE WRITTEN OPINION OF COUNSEL TO THE COMPANY, OR OTHER COUNSEL REASONABLY ACCEPTABLE TO THE COMPANY, THAT THE PROPOSED DISPOSITION IS CONSISTENT WITH ALL APPLICABLE PROVISIONS OF THE ACT AS WELL AS ANY APPLICABLE "BLUE SKY" OR SIMILAR STATE SECURITIES LAW. 4.9 Wheaton is acquiring the Securities for his own account for investment and not with a view to the sale or distribution thereof or the granting of any participation therein. Wheaton has no present intention of distributing or selling to others any of such interest or granting any participation therein. 2 4.10 It never has been represented, guaranteed or warranted by any of the Company, the Company's officers, directors, stockholders, employees or agents, or any other person, whether expressly or by implication, that (i) the Company or Wheaton will realize any given percentage of profits and/or amount or type of consideration, profit or loss as a result of the Company's activities or Wheaton's investment; or (ii) the past performance or experience of the management of the Company, or of any other person, will in any way indicate the predictable results of the Company's activities or the ownership of the Securities. 4.11 Wheaton is not acquiring the Securities as a result of or subsequent to any advertisement, article, notice or other communication published in any newspaper, magazine or similar media or broadcast over television or radio, or presented at any seminar or meeting, or any solicitation of a share exchange by a person other than a representative of the Company with whom Wheaton had a pre-existing relationship. 4.12 Wheaton is not relying on the Company with respect to the tax and other economic considerations of an investment. 5 Indemnification. 5.1 Survival of Representations and Warranties. The representations and warranties contained herein shall survive the execution and delivery of this Agreement and shall continue forever thereafter. 5.2 Indemnification for the Benefit of the Company. Wheaton acknowledges that he understands the meaning and legal consequences of the representations and warranties contained in Section 4 hereof, and agrees to indemnify and hold harmless the Company and each of the Company's officers, directors, employees and agents from and against any and all loss, damage or liability due to or arising out of a breach of any such representation or warranty. 5.3 Indemnification for the Benefit of Wheaton. The Company acknowledges that it understands the meaning and legal consequences of the representations and warranties contained in Section 3 hereof, and agrees to indemnify and hold harmless Wheaton and each of Wheaton's officers, directors, employees and agents from and against any and all loss, damage or liability due to or arising out of a breach of any such representation or warranty. 6 Company's Right of First Purchase. For such time until the date prior to the effective date of the registration statement filed in connection with the Company's initial public offering, any shares of Common Stock held by Wheaton (including, but not limited to, any of the Securities) will be subject to the Company's right of first purchase. By virtue of that right, (a) such shares of Common Stock may not be transferred during Wheaton's lifetime to any person other than members of Wheaton's Immediate Family (as defined below), a partnership whose members are Wheaton's and/or members of Wheaton's Immediate Family, or a trust for the benefit of Wheaton and/or members of Wheaton's Immediate Family, unless such transfer occurs within the 30 days immediately following either (i) the expiration of 30 days following written notice by Wheaton to the Company identifying the prospective transferee and offering the Company the first opportunity to purchase such stock at its Fair Market Value (as defined below) in cash; or (ii) the Company's election to not purchase such shares of Common Stock after receipt of such notice; and (b) upon Wheaton's death, the Company will have the right to purchase all or some of such stock at its Fair Market Value within nine months after the date of death. This right of first purchase will continue to apply to any such shares of Common Stock after the transfer during Wheaton's lifetime of such shares of Common Stock to a member of Wheaton's Immediate Family or to a family partnership or trust as aforesaid, and after any transfer of such shares of Common Stock with respect to which the the Company expressly waived its right of first purchase without also waiving it as to any subsequent transfers thereof, but it will not apply after a transfer of such shares of Common Stock with respect to which the Company was offered but did not exercise or waive its right of first purchase or more than nine months after Wheaton's death. The Company may assign all or any portion of its right of first purchase to any one or more of its stockholders, or to a 3 pension or retirement plan or trust for employees of the Company, who may then exercise the right so assigned. The Company's right of first purchase shall terminate on the date prior to the effective date of the registration statement filed in connection with the Company's initial public offering. 6.1 Certain Definitions. In addition to the terms defined elsewhere in this Agreement, the following terms will have the following definitions: 6.1.1 Fair Market Value. The "Fair Market Value" of Common Stock will mean the price at which one could reasonably expect such stock to be sold in an arm's length transaction, for cash, other than on an installment basis, to a person not employed by, controlled by, in control of or under common control with the issuer of such stock. Such Fair Market Value will be that which has currently or most recently been determined for this purpose by the Board of Directors of the Company, or at the sole discretion of the Board by an independent appraiser or appraisers selected by the Board, in either case giving due consideration to recent transactions involving shares of such stock, if any, the issuer's net worth, prospective earning power and dividend-paying capacity, the goodwill of the issuer's business, the issuer's industry position and its management, that industry's economic outlook, the values of securities of issuers whose stock is publicly traded and which are engaged in similar businesses, the effect of transfer restrictions to which such stock may be subject under law and under the applicable terms of any contract governing such stock, the absence of a public market for such stock and such other matters as the Board or its appraiser or appraisers deem pertinent. The determination by the Board or its appraiser or appraisers of the Fair Market Value will be conclusive and binding notwithstanding the possibility that other persons might make a different determination. If the Fair Market Value to be used was thus fixed more than sixteen months prior to the day as of which Fair Market Value is being determined, it will in any event be no less than the book value of the stock being valued at the end of the most recent period for which financial statements of the Company are available. 6.1.2 Immediate Family. An individual's "Immediate Family" includes only his or her spouse, parents or other ancestors, and children and other direct descendants of that individual or of his or her spouse (including such ancestors and descendants by adoption). 7 Miscellaneous. 7.1 Confidentiality. Wheaton hereby acknowledges and agrees that this Agreement is confidential, and that its terms and contents shall not be disclosed to any person other than through a press release of the Company. 7.2 Payment of Expenses.
