(a) Such Purchaser has full power and authority to enter into this Agreement and this Agreement constitutes a valid and legally binding obligation of such Purchaser,

enforceable against such Purchaser in accordance with its terms, subject to the effects of bankruptcy, insolvency, reorganization, moratorium and other similar laws relating to or affecting creditor’s rights generally, and general equitable principles (whether considered in a proceeding in equity or at law).

(b) Each Purchaser represents that: (i) it is duly organized, validly existing and in good standing in its jurisdiction of incorporation or organization and has all the requisite power and authority to purchase the Shares as provided herein; (ii) it is not an “investment company”, as that term is defined in the Investment Company Act of 1940 or the rules and regulations promulgated thereunder; (iii) such investment does not result in any violation of, or conflict with, any term or provision of the charter, bylaws or other organizational document of the Purchaser or any other instrument or agreement to which the Purchaser is a party or by which it is bound; and (iv) such investment has been duly authorized by all necessary action on behalf of the Purchaser.

(c) If the Purchaser is purchasing the Shares pursuant to this Agreement in a representative or fiduciary capacity, the representations and warranties contained herein (and in any other written statement or document delivered to the Corporation in connection herewith) shall be deemed to have been made on behalf of the person or persons for whom such Shares is being purchased.

(d) The Purchaser and the person signing this Agreement on its behalf hereby represent and warrant that the information contained in this Agreement is true and correct with respect to such stockholders or partners (and if any such stockholder or partner is itself a corporation or a partnership, with respect to all persons having an interest in such corporation or partnership, whether directly or indirectly) and that the Purchaser and the person signing this Agreement have made due inquiry to determine the truthfulness and accuracy of such information.

(e) Such Purchaser is purchasing the Shares for Purchaser’s own account and not with a view to or for sale in connection with any distribution thereof in a transaction that would violate or cause a violation of the Securities Act or the securities laws of any state or any other applicable jurisdiction. The Purchaser has not been organized solely for the purpose of acquiring the Shares.

(f) Such Purchaser is an “institutional accredited investor” as defined in Rule 501 promulgated under the Securities Act and understands and agrees that the offer and sale of the Shares hereunder have not been registered under the Securities Act or any state securities law in reliance on the availability of an exemption from such registration requirements based on the accuracy of the Purchaser’s representations in this Section 4.2.

(g) In the normal course of such Purchaser’s business or affairs, Purchaser invests in or purchases securities similar to the Shares and has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of purchasing the Shares.

(h) Purchaser understands that the Exchange Act Reports contain certain “forward-looking” information regarding the Corporation and its business, and that the Corporation’s ability to predict results or the actual effect of future plans or strategies is inherently uncertain, and undue reliance should not be placed on such statements, and Purchaser is not relying on such “forward-looking” information in deciding to purchase the Shares pursuant to this Agreement. Purchaser has had access to such financial and other information concerning the Corporation and its Subsidiaries as Purchaser deemed necessary or desirable in making a decision to purchase the Shares pursuant to this Agreement, including an opportunity to ask questions and receive answers from officers of the Corporation and to obtain additional information (to the extent the Corporation possessed such information or could acquire it without unreasonable effort or expense) necessary to verify the accuracy of any information furnished to Purchaser or to which Purchaser had access.

(i) Such Purchaser is not relying on the Corporation or any of its affiliates with respect to an analysis or consideration of the terms of or economic considerations relating to an investment in the Shares. In regard to such considerations and analysis, the Purchaser has relied on the advice of, or has consulted with, only his, her or its own advisors, other than those advisors of the undersigned affiliated with the Corporation or any of its affiliates.

(j) Such Purchaser acknowledges and is aware that there are substantial restrictions on the transferability of the Shares. Purchaser understands that the Shares have not been registered under the Securities Act and are “restricted securities” within the meaning of Rule 144 and may not be sold, transferred, or otherwise disposed of without registration under the Securities Act or an exemption therefrom. Furthermore, Purchaser acknowledges that each certificate evidencing the Shares purchased hereunder will bear a legend to the effect set forth below, and each Purchaser covenants that, except to the extent such restrictions are waived by the Corporation, such Purchaser shall not transfer the shares represented by any such certificate without complying with the restrictions on transfer described in the legend endorsed on such certificate:

THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, OR HYPOTHECATED ABSENT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR COMPLIANCE WITH RULE 144 PROMULGATED UNDER SUCH ACT, OR UNLESS THE CORPORATION HAS RECEIVED AN OPINION OF COUNSEL, SATISFACTORY TO THE CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.

Purchaser understands that the Shares will not be and except as provided in the Section 5.7 below and the Preemptive Rights Agreement, Purchaser has no right to require that the Shares be, registered under the Securities Act.

If any of the Shares become eligible for sale without registration under the Securities Act and without limitation as to amount pursuant to Rule 144 or any similar or successor provision, the Corporation shall, upon the request of the holder of such Shares acquired pursuant to this

Agreement, remove the legend set forth in Section 4.2(j) from the certificates for such Shares. In addition, if in connection with any transfer a holder of the Shares pursuant to this Agreement delivers to the Corporation an opinion of counsel which (to the Corporation’s reasonable satisfaction) is knowledgeable in securities law matters to the effect that no subsequent transfer of shares shall require registration under the Securities Act, then the Corporation promptly upon such contemplated transfer shall deliver new certificates for such shares which do not bear the Securities Act legend set forth in Section 4.2(j).

(k) Each Purchaser represents and warrants that no authorization, approval, consent, filing or registration with any federal Governmental Authority, or to the actual knowledge of the Purchaser any other Governmental Authority, is necessary in order to consummate the Transactions at the Closing Date.

The Observer Representative must be an individual who is a partner, principal, director, officer or employee of a Purchaser or an entity that directly or indirectly controls such Purchaser.

5.5 Confidentiality; Confidentiality and Standstill Agreement; Additional Standstill Commitment. For so long as a Purchaser owns any shares of Common Stock or Non-voting Common Stock, the Purchaser agrees and agrees to cause its Representatives (as defined below) (to the extent such Representatives are provided any such confidential information by the Corporation or Purchaser), to keep confidential any information obtained from the Corporation, except to the extent that such information can be shown to have been (i) previously known on a non-confidential basis by such Purchaser or its Representatives (as hereinafter defined), (ii) in the public domain through no fault of such Purchaser or its Representatives or (iii) later acquired by such Purchaser from sources other than the Corporation or any of its Subsidiaries not known by such Purchaser or its Representatives, as applicable, to be bound by any confidentiality obligation; provided that a Purchaser may disclose such information if required by judicial or administrative process or by other requirements of law or national stock exchange, subject to compliance with the following sentence.
