          WHEREAS, Amgen Inc., a Delaware corporation (the "Company") desires to
establish the Amgen Inc. Executive Nonqualified Retirement Plan to provide
supplemental retirement income benefits for a select group of management and
highly compensated employees through Company contributions, effective as of
January 1, 2001;

          NOW, THEREFORE, effective as of January 1, 2001, the Plan is hereby
adopted to read as follows:

                                   ARTICLE I.

                             TITLE AND DEFINITIONS
                             ---------------------

     1.1  Title.
          ------

          This Plan shall be known as the Amgen Inc. Executive Nonqualified
Retirement Plan.

     1.2  Definitions.
          ------------

          Whenever the following words and phrases are used in this Plan, with
the first letter capitalized, they shall have the meanings specified below.

     (a)  "Beneficiary" or "Beneficiaries" shall mean the person or persons,
including a trustee, personal representative or other fiduciary, last designated
in writing by a Participant in accordance with the procedures established by the
Committee to receive the benefits specified hereunder in the event of the
Participant's death.  However, no designation of a Beneficiary other than the
Participant's spouse shall be valid unless consented in writing by such spouse.
No Beneficiary designation shall become effective until it is filed with the
Committee.  Any designation shall be revocable at any time through a written
instrument filed by the Participant with the Committee with or without the
consent of the previous Beneficiary, (unless such previous Beneficiary was the
Participant's spouse).  If there is no Beneficiary designation in effect, or the
designated Beneficiary does not survive the Participant, then the Participant's
spouse shall be the Beneficiary.  If there is no surviving spouse, the duly
appointed and currently acting personal representative of the Participant's
estate (which shall include either the Participant's probate estate or living
trust) shall be the Beneficiary.  In any case where there is no such personal
representative of the Participant's estate duly appointed and acting in that
capacity within 90 days after the Participant's death (or such extended period
as the Committee determines is reasonably necessary to allow such personal
representative to be appointed, but not to exceed 180 days after the
Participant's death), then Beneficiary shall mean the person or persons who can
verify by affidavit or court order to the satisfaction of the Committee that
they are legally entitled to receive the benefits specified hereunder.  In the
event any amount is payable under the Plan to a minor, payment shall not be made
to the minor, but instead be paid (a) to that person's living parent(s) to act
as custodian, (b) if that person's parents are then



divorced, and one parent is the sole custodial parent, to such custodial parent,
or (c) if no parent of that person is then living, to a custodian selected by
the Committee to hold the funds for the minor under the Uniform Transfers or
Gifts to Minors Act in effect in the jurisdiction in which the minor resides. If
no parent is living and the Committee decides not to select another custodian to
hold the funds for the minor, then payment shall be made to the duly appointed
and currently acting guardian of the estate for the minor or, if no guardian of
the estate for the minor is duly appointed and currently acting within 60 days
after the date the amount becomes payable, payment shall be deposited with the
court having jurisdiction over the estate of the minor. Payment by the Company
pursuant to any unrevoked Beneficiary designation, or to the Participant's
estate if no such designation exists, of all benefits owed hereunder shall
terminate any and all liability of the Company.

     (b)  "Board of Directors" or "Board" shall mean the Board of Directors of
the Company.


     (c)  "Cause" shall mean (i) a Participant's conviction of a felony, (ii)
the engaging by Participant in conduct that constitutes willful gross neglect or
willful gross misconduct in carrying out his or her duties to the Company,
resulting, in either case, in material economic harm to the Company, unless the
Participant believed in good faith that such conduct was in, or not contrary to,
the best interests of the Company, (iii) the Participant's material breach of
any of the terms of his or her offer letter agreement or the Proprietary
Information and Inventions Agreement or (iv) the Participant's failure to follow
any lawful directive of Amgen Inc.'s Chief Executive Officer with respect to the
Participant's employment. For purposes hereof, no act, or failure to act, by
Participant shall be deemed "willful" unless done, or omitted to be done, by
Participant not in good faith.

     (d)  "Change of Control" shall be as defined under the Amgen Inc. Change of
Control Severance Plan.

     (e)  "Code" shall mean the Internal Revenue Code of 1986, as amended.

Company shall also include affiliates and subsidiaries of Amgen Inc., and any
successor corporations, if the Committee provides that such corporation shall
participate in the Plan.

     (h)  "Company Discretionary Contributions" shall mean, for each
Participant, the discretionary amount that the Company allocates to a
Participant under this Plan as determined by the Committee. Such amount may
differ from Participant to Participant, including no contributions.

     (i)  "Crediting Date" shall mean the date, as determined by the Committee,
on which a Participant's Nonqualified Retirement Account is credited with the
Company Discretionary Amount.

     (j)  "Disability" shall mean a permanent and total disability that has been
certified by the Social Security Administration prior a Participant's
Termination of Employment.



     (k)  "Disability Prorated Nonqualified Retirement Account Amount" shall
mean portion of the Nonqualified Retirement Account Amount based upon the ratio

     (l)  "Effective Date" shall mean January 1, 2001.

prorated portion of the Nonqualified Retirement Account Amount based upon the
ratio of (i) the number of full months of the Participant's active employment
with the Company and (ii) the number of months between the Participant's first
day of participation in the Plan and the Crediting Date, provided, however, that
if such a Termination of Employment occurs within 2 years after a Change of
Control of the Company, as defined in the Amgen Inc. Change of Control Severance
Plan, the Participant shall be paid (i) the Prorated Nonqualified Retirement
Account Amount plus (ii) an amount equal to the Discretionary Company
               ----
Contribution minus the sum of (x) the Prorated Nonqualified Retirement Account
Amount and (y) an amount equal to the aggregate spread between the exercise
prices of the Participant's unvested Company stock options which are in the
money and the vesting of which is accelerated by the Change of Control and the
NASDAQ closing price of the Company stock, with such spread being determined as
of the date of the Change of Control. (See Appendix B for an example).

     7.1  Unsecured General Creditor.
          ---------------------------

          Participants and their Beneficiaries, heirs, successors, and assigns
shall have no legal or equitable rights, claims, or interest in any specific
property or assets of the Company.  No assets of the Company shall be held in
any way as collateral security for the fulfilling of the obligations of the
Company under this Plan.  Any and all of the Company's assets shall be, and
remain, the general unpledged, unrestricted assets of the Company.  The
Company's obligation under the Plan shall be merely that of an unfunded and
unsecured promise of the Company to pay money in the future, and the rights of
the Participants and Beneficiaries shall be no greater than those of unsecured
general creditors.  It is the intention of the Company that this Plan be
unfunded for purposes of the Code and for purposes of Title I of ERISA.

     7.2  Restriction Against Assignment.
          -------------------------------

          The Company shall pay all amounts payable hereunder only to the person
or persons designated by the Plan and not to any other person or corporation.

pledged, assigned or transferred in any manner other than by will or the laws of
descent and distribution.  No right, title or interest in the Plan or in any
Account shall be liable for the debts, contracts or engagements of the
Participant or his successors in interest or shall be subject to disposition by
transfer, alienation, anticipation, pledge, encumbrance, assignment or any other
means whether such disposition be voluntary or involuntary or by operation of
law by judgment, levy, attachment, garnishment or any other legal or equitable
proceedings (including bankruptcy), and any attempted disposition thereof shall
be null and void and of no effect, except to the extent that such disposition is
permitted by the preceding sentence.

     (b)  Notwithstanding the provisions of a subsection, a Participant's
interest in his Account may be transferred by the Participant pursuant to a
domestic relations order that constitutes a "qualified domestic relations order"
as defined by the Code or Title 1 of ERISA.

     7.3  Withholding.
          ------------

          There shall be deducted from each payment made under the Plan or any
other Compensation payable to the Participant (or Beneficiary) all taxes that
are required to be withheld by the Company in respect to such payment or this
Plan.  The Company shall have the right to reduce any payment (or compensation)
by the amount of such of cash sufficient to provide the amount of said taxes.



     7.4   Amendment, Modification, Suspension or Termination.
           ---------------------------------------------------

           The Committee may amend, modify, suspend or terminate the Plan in
whole or in part, except that no amendment, modification, suspension or
termination shall have any retroactive effect to reduce any amounts allocated to
a Participant's Accounts.  In the event that this Plan is terminated, the
amounts allocated to a Participant's Accounts shall be distributed to the
Participant or, in the event of his or her death, his or her Beneficiary in a
lump sum within thirty (30) days following the date of termination.

           -----------------------------------------------

           In the event that any amount becomes payable under the Plan to a
person who, in the sole judgment of the Committee, is considered by reason of
physical or mental condition to be unable to give a valid receipt therefore, the
Committee may direct that such payment be made to any person found by the
Committee, in its sole judgment, to have assumed the care of such person.  Any
payment made pursuant to such termination shall constitute a full release and
discharge of the Committee and the Company.

     7.7   Limitation of Rights and Employment Relationship
           ------------------------------------------------

           Neither the establishment of the Plan nor any modification thereof,
nor the creating of any fund or account, nor the payment of any benefits shall
be construed as giving to any Participant or other person any legal or equitable
right against the Company except as provided in the Plan, and in no event shall
the terms of employment of any Employee or Participant be modified or in any be
effected by the provisions of the Plan.

     7.8   Exempt ERISA Plan
           -----------------

           The Plan is intended to be an unfunded plan maintained primarily to
provide nonqualified retirement benefits for a select group of management or
highly compensated employees within the meaning of Sections 201, 301 and 401 of
ERISA and therefore to be exempt from Parts 2, 3 and 4 of Title I of ERISA.

     7.9   Notice
           ------

           Any notice or filing required or permitted to be given to the
Committee under the Plan shall be sufficient if in writing and hand delivered,
or sent by registered or certified mail, to the principal office of the Company,
directed to the attention of the General Counsel and Secretary of the Company.

registration or certification.

     7.10  Errors and Misstatements
           ------------------------



           In the event of any misstatement or omission of fact by a Participant
