or portions of Notes being repurchased. 

 (c) Notwithstanding the foregoing, the Company shall not repurchase any
Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a Default in the payment of the Change of Control Payment upon a Change of Control Triggering Event. 

(d) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations
conflict with the Change of Control Offer provisions of the Notes, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes
by virtue of any such conflict.

indirect parent company of the surviving Person immediately after giving effect to such transaction; (4) the first day on which a majority of the members of the Board of Directors are not Continuing Directors; or (5) the adoption of a plan
relating to the Company’s liquidation or dissolution. Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control under clause (1) above if (i) the Company becomes a direct or indirect wholly-owned
subsidiary of a holding company and (ii) (A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s Voting Stock

REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON
IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 
 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 2.30% per annum
from June 30, 2011 until maturity. The Company will pay interest semi-annually in arrears on June 15 and December 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an
“Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that the first Interest Payment Date
shall be December 15, 2011; provided further that after December 15, 2011, if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the
next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date. 

  

	 	(2)	METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on
the day that is 15 days prior to the next succeeding 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 and interest 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 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 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 Mellon (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. 


 

	 	(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 June 30, 2011, 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. 

  

	 	(5)	OPTIONAL REDEMPTION. At any time prior to maturity, the Company will have the option to redeem all or a part of the Notes upon not less than 30 nor more than 60
days’ notice, at a redemption price equal to the sum of (1) 100% of the principal amount of any Notes being redeemed plus accrued and unpaid interest to, but not including, the redemption date, and (2) the Make-Whole Amount. 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 7 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.


  

	 	(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 Prospectus Supplement related to the Notes, dated June 27, 2011, 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)	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. 

  

	 	(20)	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 furnish to any Holder upon written request and without charge a copy of the Indenture and/or the Officers’ Certificate.

FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITORY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITORY TO A NOMINEE OF THE DEPOSITORY,
BY A NOMINEE OF THE DEPOSITORY TO THE DEPOSITORY OR ANOTHER NOMINEE OF THE DEPOSITORY OR BY THE DEPOSITORY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITORY OR A NOMINEE OF SUCH A SUCCESSOR DEPOSITORY. 

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY TO THE ISSUER OR ITS AGENT FOR
REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT HEREON
IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE
REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 
 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 5.65% per annum
from June 30, 2011 until maturity. The Company will pay interest semi-annually in arrears on June 15 and December 15 of each year, or if any such day is not a Business Day, on the next succeeding Business Day (each, an
“Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from the date of issuance; provided that the first Interest Payment Date
shall be December 15, 2011; provided further that after December 15, 2011, if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the
next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date. 

  

	 	(2)	 METHOD OF PAYMENT. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders of Notes at the
close of business on the day that is 15 days prior to the next succeeding 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 and interest 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 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 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 Mellon (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. 


 

	 	(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 June 30, 2011, 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. 

  

	 	(5)	OPTIONAL REDEMPTION. At any time prior to maturity, the Company will have the option to redeem all or a part of the Notes upon not less than 30 nor more than 60
days’ notice. If the Notes are redeemed before December 15, 2041 (six months prior to the maturity date of the Notes) the redemption price will equal the sum of (1) 100% of the principal amount of any Notes being redeemed, plus
accrued and unpaid interest to, but not including, the redemption date, and (2) the Make-Whole Amount. If the Notes are redeemed on or after December 15, 2041 (six months prior to the maturity date of the Notes), the redemption price will
equal 100% of the principal amount of any Notes being redeemed, plus accrued and unpaid interest to, but not including, the redemption date. 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 7 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.


  

	 	(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 Prospectus Supplement related to the Notes, dated June 27, 2011, 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)	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. 

  

	 	(20)	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 furnish to any Holder upon written request and without charge a copy of the Indenture and/or the Officers’ Certificate.
