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.
Item 5. Interest in Securities of the Issuer.
(a) As of March 10, 2008, each of the Reporting Persons may be deemed
to beneficially own 9,387,559 shares of Common Stock, representing 7,223,760
shares of Common Stock previously acquired and beneficially owned by the
Investors and 2,163,799 shares of Common Stock purchased by the Investors from
September 11, 2007 through March 10, 2008. 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.
