ITEM 5.  OTHER EVENTS

Stock Split

     On October 19, 1999, the Board of Directors of Amgen Inc. (the "Company")
declared a 2-for-1 stock split on the Company's common stock, par value $.0001
per share  (the "Common Shares"), to be effected by means of a stock dividend.
The stock split will entitle each stockholder of record on November 5, 1999 (the
"Record Date") to receive one additional Common Share for each Common Share
owned of record.

     Before the stock split, the Rights Agreement, dated as of February 18, 1997
between the Company and American Stock Transfer and Trust Company (the "Rights
Agreement") provided for one-half (1/2) right to purchase one-two thousandth
(1/2000) of a share of Series A Junior Participating Preferred Stock at $112.50
for each Common Share (the "Right").  Pursuant to Section 11.15 of the Rights
Agreement, after the stock split, each Common Share outstanding shall have
attached to it one-quarter (1/4) of a Right representing the right to purchase
one-four thousandth (1/4000) of a share of Series A Junior Participating
Preferred Stock at $56.25 (subject to possible future adjustment as provided in
the Rights Agreement).

     As soon as practicable after the Record Date, the stockholders of record on
the Record Date will be sent a share certificate representing the additional
Common Shares to which they are entitled. The Common Shares will begin trading
on a split-adjusted basis on the Nasdaq National Market on November 22, 1999.

     This filing constitutes notice of the foregoing to the holders of
securities of the Company, including the Rights, for purposes of the Rights
Agreement and no other notice will be given.
