                       RESTRICTED STOCK PURCHASE AGREEMENT


JOSEPH P. MILETICH, Amgen Inc. Grantee:

               On this 1st day of April, 2002, Amgen Inc., a Delaware
corporation (the "Company"), pursuant to its Amended and Restated 1991 Equity
Incentive Plan (the "Plan") has granted to you, the grantee named above, a right
to purchase Twenty-Seven Thousand Five Hundred (27,500) shares (the "Shares") of
the $.0001 par value common stock of the Company ("Common Stock") pursuant to
the terms of this Restricted Stock Purchase Agreement (this "Agreement") and the
Plan. Capitalized terms not defined herein shall have the meanings assigned to
such terms in the Plan.

               I.    Purchase Price. Subject to the terms and conditions of this
                     --------------
Agreement, the Shares may be purchased from the Company at a purchase price per
share of $.0001 for a total purchase price of $2.75 (the "Total Purchase
Price"). The Total Purchase Price shall be paid in cash at the time of purchase.

               II.   Repurchase Option.
                     -----------------

                     (1)   Upon termination of your employment for any reason,
other than death and permanent and total disability (with such permanent and
total disability being certified by the Social Security Administration prior to
such termination), the Company shall have the right and option to purchase from
you or any holder of the Shares as permitted under Section III(5) (a "Holder")
any or all of the Shares at the per Share purchase price paid by you for such
Shares (the "Repurchase Option").

                     (2)   The Company may exercise the Repurchase Option by
delivering personally or by registered mail, to you or a Holder within ninety
(90) days of the date of termination of your employment, a notice in writing
indicating the Company's intention to exercise the Repurchase Option and setting
forth a date for closing not later than thirty (30) days from the mailing of
such notice. The closing shall take place at the Company's office. At the
closing, the Secretary of the Company or other escrow agent as provided in
Section VI shall deliver the stock certificate or certificates evidencing the
Shares to the Company, and the Company shall deliver the purchase price
therefor.

                     (3)   At its option, the Company may elect to make payment
for the Shares to a bank selected by the Company. The Company shall avail itself
of this option by a notice in writing to you or a Holder stating the name and
address of the bank, date of closing, and waiving the closing at the Company's
office.

               (4)   If the Company does not elect to exercise the Repurchase
Option conferred above by giving the requisite notice to you or a Holder within
ninety (90) days following the date of termination of your employment, the
Repurchase Option shall terminate, and any restrictions on Shares remaining as
of the date of the termination of your employment shall lapse immediately.

               (5)   One hundred percent (100%) of the Shares shall initially be
subject to the Repurchase Option. The Shares shall be released from the
Repurchase Option in accordance with the schedule set forth in Section III(1).

         III.  Lapse of Repurchase Option.
               ---------------------------

               (1)   Subject to Sections III (2), (3) and (4), the Repurchase

               (2)   Upon termination of your employment due to your permanent
and total disability (with such permanent and total disability being certified
by the Social Security Administration prior to such termination) or your death,
then the Repurchase Option shall lapse immediately with respect to all the
Shares awarded under this Agreement. For purposes of this Agreement,
"termination of your employment" shall mean the last date you are either an
employee of the Company or an Affiliate or engaged as a consultant or director
