INTRODUCTORY STATEMENT

     This Tender Offer Statement on Schedule TO (this “Schedule TO”) relates to a proposed offer (the “Exchange Offer”) by Amgen Inc., a Delaware corporation (the “Company”), to exchange $1,000 principal amount at maturity of its Zero Coupon Convertible Notes due 2032 (the “New Notes”) for each $1,000 principal amount at maturity validly tendered and accepted of its Liquid Yield Option Notes due 2032 (the “Old Notes”), upon the terms and subject to the conditions set forth in the prospectus (as amended and supplemented from time to time, the “Prospectus”), which is part of the Company’s Registration Statement on Form S-4 (File No. 333-123293), dated the date hereof (the “Registration Statement”) and is incorporated herein by reference. The Exchange Offer has not yet commenced.

     This Schedule TO is being filed in satisfaction of the reporting requirements of Rule 13e-4(c)(2) promulgated under the Securities Exchange Act of 1934, as amended.

     (b) Securities. The Old Notes were issued under an Indenture, dated as of March 1, 2002 and supplemented as of March 2, 2005, between the Company and LaSalle Bank National Association, as trustee and paying agent (the “Paying Agent”). As of March 11, 2005, there was $2,359,102,000 aggregate principal amount at maturity of Old Notes outstanding and DTC was the sole record Holder of the Old Notes. The Old Notes mature on March 1, 2032.

     (c) Trading Market and Price. There is no established reporting system or trading market for trading in the Old Notes. However, the Company believes the Old Notes currently are traded over the counter. The Company believes that there is no practical way to accurately determine the trading history of the Old Notes. To the extent that the Old Notes are traded, prices of the Old Notes may fluctuate widely depending on trading volume, the balance between buy and sell orders, prevailing interest rates, the Company’s operating results, the market price of the Common Stock and the market for similar securities. The Paying Agent has informed us that, as of the date of this Schedule TO, all of the Old Notes are held in global form through DTC.
