(Director Equity Incentive Program)

                                             , Amgen Inc. Grantee:

On this      day of                      (the “Grant Date”), Amgen Inc., a Delaware corporation (the “Company”), pursuant to its Amgen 2009 Director Equity Incentive Program (the “Program”) which implements the Amgen Inc. 2009 Equity Incentive Plan (the “Plan”), has granted to you, the grantee named above,                      restricted stock units (the “Units”) with respect to                      Shares on the terms and conditions set forth in this Restricted Stock Unit Agreement, including any appendix hereto (as further described in Section XV below) containing special terms and conditions applicable to your country (collectively, this “Agreement”), and the Plan. Capitalized terms not defined herein shall have the meanings assigned to such terms in the Plan and/or the Program.

I. Vesting Schedule. Subject to the terms and conditions of this Agreement and in consideration for services previously rendered by you, one hundred percent (100%) of the Units shall vest upon [select a vesting date based on director’s years of service, per program:][the date hereof (the “Vesting Date”)] “)][the date (the “Vesting Date”) upon which you have provided one year of continuous service following the Grant Date; provided, however, that in the event you cease to be an Eligible Director by reason of your death or total and permanent disability (as certified by an independent medical advisor appointed by the Company prior to such termination), a prorated number of Units shall vest immediately upon such death or disability, determined by multiplying the number of unvested Units by a fraction (rounded to two decimal places), the numerator of which is the number of complete months of continuous service during the one year period following the Grant Date and the denominator of which is 12.]

II. Form and Timing of Payment. Any vested Units shall be paid by the Company in Shares (on a one-to-one basis) on, or as soon as practicable after, the Vesting Date (but in any event by the fifteenth day of the third month following the tax year in which they vest), unless you have irrevocably elected in writing by December 31 of the year preceding the Grant Date to defer the payment of such Units under one of the following options: (i) full payment of the vested Units in January of a year specified by you which shall be no earlier than the third calendar year following the calendar year in which the date of grant occurs and no later than the tenth calendar year following such year; (ii) full payment of the vested Units in January of the calendar year following the year in which you cease to be an Eligible Director (and experience a “separation from service” with the Company within the meaning of Code Section 409A) for any reason; (iii) payment of the vested Units in five substantially equal annual installments, commencing in January of the calendar year following the year in which you cease to be an Eligible Director (and experience a “separation from service” with the Company within the meaning of Code Section 409A) for any reason; or (iv) payment of the vested Units in ten substantially equal annual installments, commencing in January of the calendar year following the year in which you cease to be an Eligible Director (and experience a “separation from service” with the Company within the meaning of Code Section 409A) for any reason; provided, however, that no Shares shall be issued hereunder unless the Board determines that the consideration received by the Company in exchange for the issuance of Common Stock has a value not less than the par value thereof. Any deferral election made pursuant to this Section II shall specify the distribution schedule from the options provided in this Section II and shall be irrevocable.

III. Transferability. No benefit payable under, or interest in, this Agreement shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge and any such attempted action shall be void and no such benefit or interest shall be, in any manner, liable for, or subject to, your or your beneficiary’s debts, contracts, liabilities or torts; provided, however, nothing in this Section III shall prevent transfer (i) by will, (ii) by applicable laws of descent and distribution or (iii) to an Alternate Payee to the extent that a QDRO so provides, as further described in the Program.

IV. No Contract for Employment. This Agreement is not an employment or service contract and nothing in this Agreement shall be deemed to create in any way whatsoever any obligation on your part to continue in the employ or service of the Company or any Affiliate, or of the Company or any Affiliate to continue your employment or service with the Company or any Affiliate.

V. Notices. Any notices provided for in this Agreement, the Program or the Plan shall be given in writing and shall be deemed effectively given upon receipt or, in the case of notices delivered by the Company to you, five (5) days after deposit in the United States mail, postage prepaid, addressed to you at such address as is currently maintained in the Company’s records or at such other address as you hereafter designate by written notice to the Company.

(a) the Program and Plan are established voluntarily by the Company, are discretionary in nature and may be modified, amended, suspended or terminated by the Company at any time;

(c) your participation in the Program and Plan is voluntary;

(d) all decisions with respect to future awards, if any, will be at the sole discretion of the Company;

(e) the future value of the underlying Shares is unknown and cannot be predicted with certainty;

(f) in consideration of the grant of the Units, no claim or entitlement to compensation or damages shall arise from forfeiture of the Units resulting from termination of your service as an Eligible Director (for any reason whatsoever and whether or not in breach of

2

local labor laws) and you irrevocably release the Company from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, you shall be deemed irrevocably to have waived your entitlement to pursue such claim; and

(g) the Units and the benefits under the Program and Plan, if any, will not automatically transfer to another company in the case of a merger, takeover or transfer of liability.

XI. Severability. The provisions of this Agreement are severable and if any one or more are determined to be illegal or otherwise unenforceable, in whole or in part, the remaining provisions shall nevertheless be binding and enforceable.

XII. Change of Control.

(a) Notwithstanding anything to the contrary in this Agreement, in the event of a Change of Control, then, to the extent permitted by applicable law, the time during which the Units become vested shall automatically be accelerated so that the unvested portions of all Units shall be vested prior to the Change of Control.

(b) “Change of Control” shall mean the occurrence of any of the following:

(i) the acquisition (other than from the Company) by any person, entity or “group,” within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act (excluding, for this purpose, the Company or any of its Affiliates, or any employee benefit plan of the Company or any of its Affiliates which acquires beneficial ownership of voting securities of the Company), of beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of fifty percent (50%) or more of either the then outstanding Shares or the combined voting power of the Company’s then outstanding voting securities entitled to vote generally in the election of Directors; or

(ii) individuals who, as of April 2, 1991, constitute the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board, provided that any person becoming a Director subsequent to April 2, 1991, whose election, or nomination for election by the Company’s stockholders, was approved by a vote of at least a majority of the Directors then comprising the Incumbent Board (other than an election or nomination of an individual whose

4

initial assumption of office is in connection with an actual or threatened election contest relating to the election of the Directors of the Company, as such terms are used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act) shall be, for purposes of the Plan, considered as though such person were a member of the Incumbent Board; or

(iii) the consummation by the Company of a reorganization, merger, consolidation, (in each case, with respect to which persons who were the stockholders of the Company immediately prior to such reorganization, merger or consolidation do not, immediately thereafter, own more than fifty percent (50%) of the combined voting power entitled to vote generally in the election of Directors of the reorganized, merged or consolidated company’s then outstanding voting securities) or a liquidation or dissolution of the Company or of the sale of all or substantially all of the assets of the Company; or

(iv) any other event which the Incumbent Board in its sole discretion determines constitutes a Change of Control.

Notwithstanding anything in any Award Agreement to the contrary, if a Change of Control constitutes a payment event with respect to any Award that is subject to United States income tax and which provides for a deferral of compensation that is subject to Section 409A of the Code, the transaction or event described in subsection (i), (ii), (iii) or (iv) must also constitute a “change in control event,” as defined in U.S.Treasury Regulation §1.409A-3(i)(5), in order to constitute a Change of Control for purposes of payment of such Award.

XIII. Plan and Program. This Agreement is subject to all the provisions of the Plan and Program and their provisions are hereby made a part of this Agreement, including without limitation the provisions of Section 9.5 of the Plan relating to Restricted Stock Units, and is further subject to all interpretations, amendments, rules and regulations which may from time to time be promulgated and adopted pursuant to the Plan.
