2.                                      BUYER’S REPRESENTATIONS AND WARRANTIES.  The Buyer hereby represents and warrants that as of the date hereof:

(a)                           Organization; Authority.  The Buyer is a French Société en commandite par actions duly formed, validly existing and in good standing under the laws of the jurisdiction of its organization with the requisite power and authority to enter into and to consummate the transactions contemplated by this Agreement and each other Transaction Document to which it is or will be a party and otherwise to carry out its obligations hereunder and thereunder.  This Agreement and each other Transaction Document to which the Buyer is or will be a party have been, or when executed and delivered will have been, duly authorized, executed and delivered by the Buyer and constitute or, when executed and delivered, will constitute the legal, valid and binding obligations of the Buyer, enforceable against the Buyer in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar Laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

(b)                           No Public Sale or Distribution.  The Buyer is acquiring the Shares for its own account and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempt from the registration requirements under the 1933 Act.  The Buyer does not presently have any agreement or understanding, directly or indirectly, with any Person to resell or distribute any of the Shares in violation of the 1933 Act.

(c)                            Accredited Investor Status; Sophistication.

(i)                                     The Buyer is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D.

(ii)                                  The Buyer has, by reason of its business and financial experience, such knowledge, sophistication and experience in financial and business matters and in making investment decisions of the type contemplated hereby that it is capable of (A) evaluating the merits and risks of an investment in the Shares and making an informed investment decision, (B) protecting its own interests (financially or otherwise), and (C) bearing the economic risk of such investment for an indefinite period of time.

(d)                           Reliance on Exemptions.  The Buyer understands that the Shares are being offered and sold to it 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 the Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Buyer set forth herein in order to determine the availability of such exemptions and the eligibility of the Buyer to acquire the Shares.

(e)                            Certain Securities Transactions.  During the period (the “Pre-Announcement Period”) beginning with the date on which the Buyer commenced discussions with the Company in respect of the transactions contemplated hereby and ending on the Closing Date, neither the Buyer nor any Affiliate controlled by the Buyer, nor to the knowledge of the Buyer

2

any Affiliate controlling the Buyer or under common control with the Buyer, has entered, or will enter, into any transaction in respect of or involving the Common Stock or any Convertible Securities or Options, including any purchase or sale, derivative or hedging transaction, other than the transactions contemplated by this Agreement.  Without limiting the foregoing, during the Pre-Announcement Period, the Buyer has not and will not engage in any transaction constituting a “short sale” (as defined in Rule 200 of Regulation SHO under the Securities Exchange Act of 1934, as amended (the “1934 Act”)) of shares of Common Stock or establish an open “put equivalent position” (within the meaning of Rule 16a-1(h) under the 1934 Act) with respect to the Common Stock.

(f)                             Information.  The Buyer and its advisors, if any, have received all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Shares which have been requested by the Buyer.  The Buyer and its advisors, if any, have been afforded the opportunity to ask questions of, and have received answers from, the Company regarding the Company and the transactions contemplated hereby.  Neither such inquiries nor any other due diligence investigations conducted by the Buyer or its advisors or representatives, nor any other statement made by Buyer in this Section 2, shall modify, amend or affect the Company’s representations and warranties contained herein or the Buyer’s right to rely thereon.  The Buyer understands that its investment in the Shares involves a high degree of risk.  The Buyer has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Shares.

(g)                            No Governmental Review.  The Buyer 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 Shares or the fairness or suitability of the investment in the Shares nor have such authorities passed upon or endorsed the merits of the offering of the Shares.

(h)                           Transfer or Resale.  The Buyer understands that:

(i)                                     the Shares have not been and are not being registered under the 1933 Act or any state securities Laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder and sold, assigned or transferred pursuant to an effective registration statement, (B) the Buyer shall have delivered to the Company an opinion of counsel reasonably acceptable to the Company, which opinion shall be in a form reasonably acceptable to the Company and the transfer agent for the Common Stock, to the effect that such Shares to be sold, assigned or transferred have been or are being sold, assigned or transferred pursuant to an exemption from such registration, or (C) the Buyer provides the Company with reasonable assurance, and certifications to the effect, that (I) such Shares have been or are being sold, assigned or transferred pursuant to Rule 144 promulgated under the 1933 Act (or a successor rule thereto) (“Rule 144”) or Rule 144A promulgated under the 1933 Act (or successor rule thereto) (“Rule 144A”) or (II) the Buyer is not an Affiliate of the Company and the Shares can then be sold by the Buyer pursuant to Rule 144 without any restrictions or limitations thereunder and without compliance with the current public information requirement thereof;

3

(ii)                                  any sale of the Shares made in reliance on Rule 144 or Rule 144A shall be made in accordance with the terms of Rule 144 or Rule 144A, as applicable, and, further, if Rule 144 or Rule 144A is not applicable, any resale of the Shares under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the 1933 Act) may require compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC thereunder; and

(iii)                               neither the Company nor any other Person is under any obligation to register the Shares under the 1933 Act or any state securities Laws or to comply with the terms and conditions of any exemption thereunder; and

(iv)                              the Shares are subject to the transfer restrictions set forth in Section 4(b).

The Shares may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by the Shares and such pledge of Shares shall not be deemed to be a transfer, sale or assignment of the Shares hereunder, and, except as required by applicable Law, the Buyer shall not be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement, including this Section 2(h), in connection with such a pledge.

(i)                               Legends.  The Buyer understands that the stock certificates representing the Shares, except as set forth below, shall bear any legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such stock certificates in violation of the restrictions on transfer set forth herein):

(d)                           Stock Certificates.  In connection with the Closing, the Company shall instruct the Transfer Agent to issue the stock certificate representing the Shares (with the restrictive legends set forth in Section 2(i)) as required by this Agreement and take such actions as shall be reasonably requested by the Transfer Agent such that such stock certificate shall be delivered to the Buyer within five (5) Business Days after the Closing Date.
