Source and Amount of Funds or Other Consideration. In 2000, prior to the Company's initial public offering (the "IPO"), the Investors acquired shares of the Company's Series B Convertible Preferred Stock. Upon the closing of the IPO on February 6, 2002 and after giving effect to a previously announced stock split, these shares automatically converted into 7,223,760 shares of Common Stock. No additional consideration was paid upon the conversion of these shares. The total amount of funds used by the Investors to purchase an aggregate of 2,163,799 shares of Common Stock from September 11, 2007 through March 10, 2008 was $21,634,083.93, net of brokerage commissions and other transactions costs. All of the funds required to acquire shares of Common Stock were furnished from the working capital of the Investors. Page 9 of 15 Pages CUSIP NO. 98985T 10 9 Item 4. Purpose of Transaction. The initial acquisition by the Investors of the Company's Series B Convertible Preferred Stock convertible into shares of Common Stock and the acquisition by the Investors of 2,163,799 additional shares of Common Stock were effected because of the Reporting Persons' belief that Common Stock represented, and continues to represent, an attractive investment. The Reporting Persons may from time to time acquire additional shares of the Company's Common Stock or engage in discussions with the Company concerning further acquisitions of shares of its Common Stock or further investments in the Company. Such further acquisitions or investments could be material. The Reporting Persons intend to review their investment in the Company on a continuing basis and, depending on the price and availability of shares of Common Stock, subsequent developments affecting the Company, the Company's business and prospects, other investments and business opportunities available to the Reporting Persons, general stock market and economic conditions, tax considerations and other factors considered relevant, may decide at any time to increase, or to decrease, the size of their investment in the Company or to sell any or all of the securities of the Company that they hold. Each of the Investors is a partnership engaged in making private equity and related investments. In connection with that business, the Reporting Persons frequently seek to make significant investments in the entities in which they invest, engage in discussions with the management of the entities in which they invest and/or seek and often obtain representation on the boards of directors of the entities in which they invest. The Reporting Persons may in the future seek to engage in discussions with management of the Company concerning the business, strategy and/or operations of the Company, concerning the possibility of additional representatives of the Reporting Persons becoming members of the board of directors of the Company and/or concerning potential investments by the Reporting Persons in securities of the Company and/or its subsidiaries. Such discussions may relate to one or more of the transactions specified in clauses (a) through (j) of Item 4 of Schedule 13D. Two of the nine members of the Company's board of directors as of the date hereof, Jonathan S. Leff and Dr. David I. Hirsh, were designated by the Reporting Persons. Mr. Leff is a general partner of WP and a Managing Director and Member of WP LLC. Dr. Hirsh is the Executive Vice President for Research at Columbia University and serves on the Life Sciences Advisory Board of Warburg Pincus. Except as set forth in this statement, none of the Reporting Persons, nor, to the best of their knowledge, any person listed on Schedule I hereto or in Item 1(a) or (d) above, has any plans or proposals that relate to or would result in: (a) the acquisition by any person of additional securities of the Company, or the disposition of securities of the Company; (b) an extraordinary Page 10 of 15 Pages CUSIP NO. 98985T 10 9 corporate transaction, such as a merger, reorganization or liquidation, involving the Company or any of its subsidiaries; (c) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries; (d) any change in the present Board of Directors or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (e) any material change in the present capitalization or dividend policy of the Company; (f) any other material change in the Company's business or corporate structure; (g) changes in the Company's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Company by any person; (h) causing a class of securities of the Company to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) a class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act; or (j) any action similar to any of those enumerated above.

In the aggregate, these shares represent 13.7% of the outstanding shares of Common Stock, based on the 68,626,883 shares of such stock outstanding as of February 22, 2008, as reported in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2007, filed with the Securities and Exchange Commission on February 29, 2008. The Reporting Persons are making this single, joint filing because they may be deemed to constitute a "person" or "group" within the meaning of Section 13(d)(3) of the Exchange Act. The filing of this Schedule 13D shall not be construed as an admission of such beneficial ownership or that the Reporting Persons constitute a person or group. As a result of the Shareholders' Agreement described in Item 6 below, the Reporting Persons may be deemed to constitute a "group," within the meaning of Section 13(d)(3) of the Exchange Act, with Novo Nordisk Pharmaceuticals, Inc. and certain of its affiliates (collectively, "NNPI"). As a result, the Reporting Persons may be deemed to beneficially own any shares of Common Stock that are beneficially owned by NNPI as described in reports filed, or that may be filed, by NNPI with the SEC. The Group Members disclaim beneficial ownership of any shares of Common Stock owned by NNPI. According to the Company's Definitive Proxy Statement on Schedule 14A filed with the Securities and Exchange Commission on April 19, 2007, NNPI owns Page 11 of 15 Pages CUSIP NO. 98985T 10 9 21,759,861 shares of Common Stock, or 31.7% of the outstanding shares of Common Stock, based on the 68,626,883 shares of such stock outstanding as of February 22, 2008, as reported in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2007, filed with the Securities and Exchange Commission on February 29, 2008. The filing of this Schedule 13D shall not be construed as an admission of such beneficial ownership or that the Reporting Persons or the Group Members constitute a person or group with NNPI. Each of WP, WP LLC, WPP LLC and Messrs. Kaye and Landy disclaims beneficial ownership of Common Stock of the Company. (b) Each of the Reporting Persons shares the power to vote or to direct the vote and to dispose or to direct the disposition of the 9,387,559 shares of Common Stock it may be deemed to beneficially own. (c) Information concerning transactions in the shares of Common Stock effected by the Reporting Persons during the past 60 days is set forth in Schedule II hereto and is incorporated herein by reference. All of such transactions were effected on the NASDAQ Stock Market in open market purchases. No other transactions in Common Stock were effected during the past sixty days by the Group Members or any of the persons set forth on Schedule I hereto. (d) Except as set forth in this Item 5, no person other than each respective record owner referred to herein of the shares of Common Stock is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, such shares of Common Stock. (e) Not applicable. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.
