on Schedule TO filed by Alkermes, Inc. (the "company") with the Securities and
Exchange Commission on November 26, 2002, pursuant to Section 13(e) of the
Securities Exchange Act of 1934, as amended, in connection with its offer to
exchange (the "exchange offer") up to all of its outstanding 3.75% Convertible
Subordinated Notes due 2007 for 6.52% Convertible Senior Subordinated Notes due
December 31, 2009 (the "new notes") upon the terms and subject to the conditions
set forth in the preliminary prospectus and in the related Letter of
Transmittal, which are Exhibit (a)(1) and Exhibit (a)(3) to this Tender Offer
Statement, respectively. The company filed an Amendment No. 1 to this Tender
Offer Statement on December 17, 2002.
