 A-2 








 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below
unless otherwise indicated. 
  

	 	(1)	INTEREST. Amgen Inc., a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at a rate per annum equal to three-month
LIBOR plus .08% and shall pay the Additional Amounts (as defined in the Registration Rights Agreement), if any, payable pursuant to Section 4 of the Registration Rights Agreement referred to below. The Company will pay interest and Additional
Amounts, if any, in cash quarterly in arrears on August 28, 2007, November 28, 2007, February 28, 2008, May 28, 2008, August 28, 2008 and November 28, 2008 (each, an “Interest Payment
Date”). If any Interest Payment Date falls on a day that is not a Business Day, the Company will postpone the Interest Payment Date to the next succeeding Business Day unless that Business Day is in the next succeeding calendar month, in
which case the Interest Payment Date will be the immediately preceding Business Day. 

 The Company shall appoint a calculation
agent (the “Calculation Agent”), which shall initially be the Trustee. The Calculation Agent shall calculate the interest rate, except that the interest rate in effect for the period from May 30, 2007 to and including
August 28, 2007 (the “Initial Reset Date”), will be established by the Company as the rate for deposits in United States dollars having a maturity of three months commencing on May 30, 2007 that appears on Reuters Screen
LIBOR01 Page as of 11:00 a.m., London Time, on the second Business Day preceding May 30, 2007, plus .08% (the “Initial Interest Rate”). The Calculation Agent shall reset the interest rate on each Interest Payment Date (each, an
“Interest Reset Date”). The second Business Day preceding an Interest Reset Date shall be the “Interest Determination Date” for that Interest Reset Date. The interest rate in effect on each day that is not an
Interest Reset Date will be the interest rate determined as of the Interest Determination Date pertaining to the immediately preceding Interest Reset Date. The interest rate in effect on any day that is an Interest Reset Date will be the interest
rate determined as of the Interest Determination Date pertaining to that Interest Reset Date, except that the interest rate in effect for the period from and including May 30, 2007 to the initial interest reset date will be the Initial Interest
Rate. The interest rate will be computed on the basis of a 360-day year and the actual number of days elapsed. 
 “LIBOR”
will be determined by the Calculation Agent in accordance with the following provisions: 
 (1) With respect to any Interest
Determination Date, LIBOR will be the rate for deposits in United States dollars having a maturity of three months commencing on the first day of the applicable interest period that appears on Reuters Screen LIBOR01 Page as of 11:00 a.m., London
time, on that Interest Determination Date. If no rate appears, then LIBOR, in respect to that Interest Determination Date, will be determined in accordance with the provisions described in (2) below. 
 (2) With respect to an Interest Determination Date on which no rate appears on Reuters Screen LIBOR01 Page (or such other page as may
replace such page), as specified in (1) above, the Calculation Agent will request the principal London offices of each of four major reference banks in the London interbank market, as selected by the Calculation Agent, to provide the
Calculation Agent with its offered quotation for deposits in United States dollars for the period of three months, commencing on the first 

  

 A-3 








 
day of the applicable interest period, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that Interest Determination
Date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time. If at least two quotations are provided, then LIBOR on that Interest Determination Date will be the arithmetic mean
of those quotations. If fewer than two quotations are provided, then LIBOR on the Interest Determination Date will be the arithmetic mean of the rates quoted at approximately 11:00 a.m., in The City of New York, on the Interest Determination Date by
three major banks in The City of New York selected by the Calculation Agent for loans in United States dollars to leading European banks, having a three-month maturity and in a principal amount that is representative for a single transaction in
United States dollars in that market at that time. If at least two such rates are so provided, LIBOR on the Interest Determination Date will be the arithmetic mean of such rates. If fewer than two such rates are so provided, LIBOR on the Interest
Determination Date will be LIBOR in effect with respect to the immediately preceding Interest Determination Date. 
 “Reuters Screen
LIBOR01” means the display designated as Reuters Monitor Money Rates Service or any other successor service or page as may replace Reuters Screen LIBOR01 for the purpose of displaying London interbank offered rates of major banks.

  

	 	(2)	METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) and Additional Amounts, if any, to the Persons who are registered Holders of Notes at the
close of business on the day that is 15 days prior to the relevant Interest Payment Date (whether or not such day is a Business Day), even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as
provided in Section 2.13 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, interest and Additional Amounts, if any, at the office or agency of the Company maintained for such purpose in the Borough
of Manhattan, the City and State of New York (or, if the Company fails to maintain such office or agency, at the corporate trust office of the trustee in New York, New York or if the trustee does not maintain an office in New York, at the office of
a paying agent in New York), or, at the option of the Company, payment of interest and Additional Amounts, if any, may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by
wire transfer of immediately available funds will be required with respect to principal of and interest and Additional Amounts, if any, on, all Global Securities and all other Notes the Holders of which will have provided wire transfer instructions
to the Company or the Paying Agent. Such payment will be in the currency of the United States of America. 

  

	 	(3)	PAYING AGENT AND REGISTRAR. Initially, The Bank of New York (as successor to JPMorgan Chase Bank, N.A.), the Trustee under the Indenture, will act as Paying Agent and Registrar. The
Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity but shall not act as Calculation Agent. 

  

	 	(4)	INDENTURE. The terms of the Notes include those stated in the Indenture dated August 4, 2003 between the Company and the Trustee (the “Indenture”), and those
made part of the Indenture by the Officers’ Certificate dated May 30, 2007 delivered pursuant thereto (the “Officers’ Certificate”) and the TIA. The Notes are subject to all such terms, and the Holders are referred to
the Indenture and the TIA for a statement of them. 

  

 A-4 









	 	(5)	OPTIONAL REDEMPTION. The Notes may be redeemed at any time on or after November 28, 2007, in whole or from time to time in part, at a redemption price equal to 100% of the
principal amount of the Notes being redeemed plus accrued and unpaid interest on the principal amount being redeemed to the date of redemption. Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on the
Notes or portions thereof called for redemption on the applicable redemption date. 

  

	 	(6)	NOTICE OF REDEMPTION. Notice of redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its
registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction or discharge of the Indenture. Notes in
denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the Notes held by a Holder are to be redeemed. 

  

	 	(7)	MANDATORY REDEMPTION. Except as provided in Section 8 below, the Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes.


  

	 	(8)	CHANGE OF CONTROL TRIGGERING EVENT. In the event of a Change of Control Triggering Event, the Holders may require the Company to purchase for cash all or a portion of their Notes at
a purchase price equal to 101% of the principal amount of the notes, plus accrued and unpaid interest, if any, pursuant to the provisions of Section 9 of the Officers’ Certificate. 

  

	 	(9)	DEFEASANCE PRIOR TO MATURITY. The Indenture contains provisions for defeasance of (i) the entire indebtedness of the Notes or (ii) certain covenants and Events of Default
with respect to the Notes, in each case upon compliance with certain conditions set forth therein. 

  

	 	(10)	RESTRICTIVE COVENANTS. The Indenture and the Officers’ Certificate impose certain limitations on the Company and its Subsidiaries, including limitations on the Company’s
and its Subsidiaries’ ability to create or incur certain Liens on any of their respective properties or assets and to enter into certain sale and lease-back transactions and on the Company’s ability to engage in mergers or consolidations
or the conveyance, transfer or lease of all or substantially all of its properties and assets. These limitations are subject to a number of important qualifications and exceptions and reference is made to the Indenture and the Officers’
Certificate for a description thereof. 

  

	 	(11)	DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000. The transfer of Notes may be
registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any
taxes and fees required by law or permitted by the Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part.
Also, the Company need not exchange or register the transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.


  

 A-5 









	 	(12)	PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes. 

  

	 	(13)	AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in
aggregate principal amount of the then outstanding Notes voting as a single class, and any existing Default or Event or Default or compliance with any provision of the Indenture or the Notes may be waived with the consent of the Holders of a
majority in aggregate principal amount of the then outstanding Notes voting as a single class. Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to cure any ambiguity, defect or inconsistency, to
comply with Article V of the Indenture, to provide for uncertificated Notes in addition to or in place of certificated Notes, to make any change that would not adversely affect the rights under the Indenture of any such Holder, to provide for the
issuance of any additional notes as permitted by the Indenture, to appoint a successor trustee with respect to the notes and to add to or change any of the provisions of the Indenture necessary to provide for the administration of the trusts in the
indenture by more than one trustee, or to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA. No amendment to cure any ambiguity, defect or inconsistency in the Indenture made
solely to conform the Indenture to the description of notes contained in the Offering Memorandum related to the Notes, dated May 24, 2007 will be deemed to adversely affect the interests of the Holders of the Notes. 

  

	 	(14)	DEFAULTS AND REMEDIES. If an Event of Default shall occur and be continuing, the principal of the Notes may be declared (or, in certain cases, shall ipso facto become) due and
payable in the manner and with the effect provided in the Indenture. 

  

	 	(15)	TRUSTEE DEALINGS WITH COMPANY. The Trustee under the Indenture, in its individual or any other capacity, may deal with the Company or an Affiliate of the Company with the same
rights it would have if it were not Trustee. 

  

	 	(16)	NO RECOURSE AGAINST OTHERS. A director, officer, employee or stockholder of the Company shall not have any liability for any obligations of the Company under the Notes or the
Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for the issuance of
the Notes. 

  

	 	(17)	AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. 

  

	 	(18)	ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (=
joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

  

	 	(19)	REGISTRATION RIGHTS OF HOLDERS. In addition to the rights provided to Holders of Notes under the Indenture, Holders of restricted Notes will have all the rights set forth in the
Registration Rights Agreement, dated as of May 30, 2007, between the Company and the other parties named on the signature pages thereof (the “Registration Rights Agreement”). 

  

 A-6 









	 	(20)	CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company has caused CUSIP numbers to be printed on the
Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance
may be placed only on the other identification numbers placed thereon. 

  

	 	(21)	GOVERNING LAW. THE INTERNAL LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE THE INDENTURE AND THIS NOTE WITHOUT GIVING EFFECT TO APPLICABLE PRINCIPLES OF CONFLICTS
OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY. 

 The Company will
