 6. Solely with respect to the Notes, Section 2.7 of the Indenture shall be replaced in
its entirety with the following: 
 “SECTION 2.7. Transfer and Exchange. Where Notes of a Series are presented to
the Registrar with a request to register a transfer or to exchange them for an equal principal amount of Notes of the same Series, the Registrar shall register the transfer or make the exchange if its requirements for such transactions are met. To
permit registrations of transfers and exchanges, the Company shall execute and the Trustee, upon receipt of a Company Order directing the authentication and delivery thereof, shall authenticate and deliver Notes in any authorized denominations in an
aggregate principal amount equal to the principal amount of such Global Notes in exchange for such Global Notes. No service charge shall be made for any registration of transfer or exchange (except as otherwise expressly permitted herein), but the
Company and the Trustee may require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith (other than any such transfer tax or similar governmental charge payable upon exchanges pursuant
to Sections 2.11, 3.6 or 9.6 of the Indenture). 
 Neither the Company nor the Registrar shall be required to issue, register
the transfer of, or exchange Notes of any Series (a) for the period beginning at the opening of business fifteen days immediately preceding the mailing of a notice of redemption of Notes of that Series selected for redemption and ending at the
close of business on the day of such mailing, (b) to register the transfer of or exchange Notes of any Series selected, called or being called for redemption as a whole or the portion being redeemed of any such Notes selected, called or being
called for redemption in part, or (c) which the Holder has tendered (and not withdrawn) for repurchase in connection with a Change of Control Offer (as defined in Section 4.5 of the Indenture). 

Prior to the due presentation for registration of transfer of any Notes, the Company, the Trustee, the Paying Agent and the Registrar may
deem and treat the person in whose name such Notes are registered as the absolute owner of such Notes for the purpose of receiving payment of principal of and interest, if any, on such Notes and for all other purposes whatsoever, whether or not such
Notes are overdue, and none of the Company, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary. 
 Any Holder of a Global Note shall, by acceptance of such Global Note, agree that transfers of beneficial interest in such Global Note may be effected only through a book-entry system maintained by
Euroclear and/or Clearstream (and/or its or their successor clearing system(s)) and their respective direct and indirect participants, as the case may be, and that ownership of a beneficial interest in the Note shall be required to be reflected in a
book-entry system. So long as the Global Notes remain outstanding and are held by or on behalf of the Common Depositary, transfer of beneficial interests in a Global Note and transfers increasing or decreasing the aggregate principal amount of a
Global Note may be conducted only in accordance with the rules and procedures of Euroclear and/or Clearstream (and/or its or their successor clearing system(s)), as the case may be. In the event a Global Note, or any portion thereof, is redeemed,
Euroclear and/or Clearstream, as applicable, will distribute the amount received by them in respect of the Global Note so redeemed to the holders of the book-entry interests in such Global Note from the amount received by it in respect of the
redemption of such Global Note.”

 7. Solely with respect to the Notes, Section 2.14.2 of the Indenture shall be replaced
in its entirety with the following: 
 “SECTION 2.14.2. Transfer and Exchange. Notwithstanding any provisions to the
contrary contained in Section 2.7 of the Indenture and in addition thereto, owners of book-entry interests will receive certificated notes in registered form (the “Certificated Notes”) only in the following circumstances:
(1) if either Depositary notifies the Company that it is unwilling or unable to continue as Depositary or that the Common Depositary with whom any Global Note is deposited is unwilling or unable to continue to act as Common Depositary and a
successor Depositary for such Global Notes is not appointed by the Company within 90 days after the Company receives such notice, (2) in whole, but not in part, at any time if the Company in its sole discretion determines that any Global Note
should be exchanged for Certificated Notes, or (3) if the owner of a book-entry interest requests such exchange in writing delivered through either Euroclear or Clearstream in the event that any of the Notes has become immediately due and
payable in accordance with Sections 6.1 and 6.2 of the Indenture. In each case the Company shall execute, and the Trustee, upon receipt of a Company Order (copied to the Paying Agent, Registrar and Common Depositary) directing the authentication and
delivery thereof, shall authenticate and deliver, Certificated Notes in any authorized denominations in an aggregate principal amount equal to the principal amount of such Global Notes in exchange for such Global Notes. Upon the exchange of such
Global Notes for Certificated Notes, the Global Notes shall be cancelled by the Trustee. Upon receipt of notice from the Depositary in accordance with this subsection, Euroclear and/or Clearstream (and/or its or their successor clearing system(s))
and the Trustee, as the case may be, and the Company shall use its commercially reasonable efforts to make arrangements with the Common Depositary for the exchange of interests in the Global Notes for Certificated Notes and cause the requested
Certificated Notes to be executed and delivered to the Registrar in sufficient quantities and authenticated by the Trustee for delivery to Holders. Holders exchanging interests in the Global Notes for Certificated Notes shall be required to provide
to the Registrar, through the relevant clearing system (and in separate writings, if required by the Trustee, Paying Agent and/or Registrar), written instructions and other information required by the Company and the Registrar to complete, execute
and deliver such Certificated Notes. Certificated Notes delivered in exchange for the Global Notes or beneficial interests therein shall be registered in the names, and issued in any approved denominations, requested by the relevant clearing system.

 Other than as provided for in this Section 2.14.2 of the Indenture, the Global Notes are not exchangeable for a
Certificated Note or Certificated Notes. 
 Prior to the expiration of the Restricted Period, the transferor of any Global Note
or Certificated Note shall be required to deliver a duly completed Regulation S Certificate to the Trustee prior to such transfer. Upon and after the expiration of the Restricted Period, no such certification shall be required with respect to such
transfers.”

 8. Solely with respect to the Notes, Section 2.14.3 of the Indenture shall be replaced
in its entirety with the following: 
 “SECTION 2.14.3. Form of Legend for Global Notes. Each Global Note
(i) shall be delivered by or on behalf of the Trustee to, and registered in the name of the nominee of, the Common Depositary and (ii) shall also bear a legend substantially to the following effect or as may be appropriate: 

“THIS SECURITY HAS NOT BEEN AND WILL NOT BE REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE SECURITIES ACT) AND MAY
NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, UNITED STATES PERSONS EXCEPT IN CERTAIN TRANSACTIONS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS LEGEND SHALL CEASE TO APPLY UPON THE
EXPIRY OF THE PERIOD OF 40 DAYS AFTER THE COMPLETION OF THE DISTRIBUTION OF ALL THE NOTES OF THE SERIES OF WHICH THIS NOTE FORMS PART.” 
 9. In addition to the provisions set forth in Article IV of the Indenture, the following additional provisions shall apply to the Notes (and only the Notes) and shall be incorporated into the Indenture
with respect to the Notes (and only the Notes):

Section 5 of the Security, the Company will be required to make an offer (the “Change of Control Offer”) to each Holder to repurchase all or any part (equal to €100,000 or multiples of €1,000 in excess thereof in the
case of the Euro Notes and £100,000 and multiples of £1,000 in excess thereof in the case of the Sterling Notes) of that Holder’s Notes on the terms set forth in such Security. In the Change of Control Offer, the Company shall be
required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of repurchase (the “Change of Control Payment”).
Within 30 days following any Change of Control Triggering Event, a notice prepared by the Company will be provided to Holders describing the transaction that constitutes the Change of Control Triggering Event and offering to repurchase the Notes on
the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is provided (the “Change of Control Payment Date”); provided, however, that in no event
will the Change of Control Payment Date occur prior to the date 90 days following the First Issue Date. 
 (b) On the Change of
Control Payment Date, the Company shall, to the extent lawful:

 4 









	 	(ii)	by 10:00 a.m., London time, deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly
tendered; and 

  

	 	(iii)	deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes
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. 
 (e) For the purposes of this Section 4.5 only, the following definitions shall apply:

 “Beneficial Owner” shall be determined in accordance with Rules 13d-3 and 13d-5 under the Exchange Act or

 “Change of Control” means the occurrence of any of the following: (1) the consummation of any
transaction (including, without limitation, any merger or consolidation) the result of which is that any Person or Group (other than the Company or one of its Subsidiaries) becomes the Beneficial Owner, directly or indirectly, of more than 50% of
the Company’s Voting Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; provided, however, that a
Person shall not be deemed Beneficial Owner of, or to own beneficially, (A) any securities tendered pursuant to a tender or exchange offer made by or on behalf of such Person or any of such Person’s affiliates until such tendered
securities are accepted for purchase or exchange thereunder, or (B) any securities if such beneficial ownership (i) arises solely as a result of a revocable proxy delivered in response to a proxy or consent solicitation made pursuant to
the applicable rules and regulations under the Exchange Act, and (ii) is not also then reportable on Schedule 13D (or any successor schedule) under the Exchange Act; (2) the direct or indirect sale, transfer, conveyance or other

Persons or Groups (other than the Company or one of its Subsidiaries); provided that 

  
 5 








 
none of the circumstances in this clause (2) will be a Change of Control if the Persons that beneficially own the Company’s Voting Stock immediately prior to the transaction own,
directly or indirectly, shares with a majority of the total voting power of all outstanding voting securities of the surviving or transferee Person that are entitled to vote generally in the election of that Person’s board of directors,
managers or trustees immediately after the transaction; (3) the Company consolidates with, or merges with or into any Person, or any Person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in
which any of the Company’s outstanding Voting Stock or the Voting Stock of such other Person is converted into or exchanged for cash, securities or other property, other than such transaction where the shares of the Company’s Voting Stock
outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving Person or any direct or 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 immediately prior to that transaction or (B) immediately
following that transaction no Person (other than a holding company satisfying the requirements of this sentence) is the Beneficial Owner, directly or indirectly, of more than 50% of the Voting Stock of such holding company.

identification or information reporting requirements concerning the nationality, residence, identity or connection with a Relevant Taxing Jurisdiction of the Holder or beneficial owner of such Note, if compliance is required by statute or by
regulation of the Relevant Taxing Jurisdiction as a precondition to relief or exemption from such Taxes (including the submission of an applicable United States Internal Revenue Service (“IRS”) Form W-8 (with any required attachments)) or

that the Holder or beneficial owner thereof would have been entitled to Additional Amounts had the Notes been presented for payment on any date during such 30 day period; 
 (9) to any withholding or deduction in respect of any tax, assessment or governmental charge where such withholding or deduction is imposed on a payment to an individual and is required to be made
pursuant to European Council Directive 2003/48/EC or any other directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000 or any law implementing or complying with, or introduced in order to conform to, such

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 4.375% per annum
from December 5, 2011 until maturity. The Company will pay interest in cash annually in arrears on December 5 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 5,
2012; provided further that after December 5, 2012, 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 one Business Day prior to the next succeeding Interest Payment Date, 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 specified office or agency of the Paying Agent in the United Kingdom; provided that payment by wire transfer of immediately available funds will be
required with respect to principal of and interest on all Global Securities registered in the name of or held by a nominee of Euroclear or Clearstream to the account specified by the Holder or Holders thereof; provided, further, that
if certificated Notes are issued, the Company, at its option, may make payments by check mailed to the Holders at their addresses set forth in the register of Holders. Such payment will be in Euros. 


 

	 	(3)	PAYING AGENT AND REGISTRAR. Initially, The Bank of New York Mellon, London Branch, 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 December 5, 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)	 REDEMPTION UPON CHANGES IN WITHHOLDING TAXES. If (a) as a result of any change in, or amendment to, the laws (or any regulations or rulings
promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein having power to tax) (a “Relevant Taxing Jurisdiction”), or any change in, or amendment to, the official position
regarding the application or interpretation of such laws, regulations or rulings (including by virtue of a holding, judgment or order by a court of competent jurisdiction or a change in published administrative practice), which change or amendment
is announced on or after the date of the Offering Memorandum related to the Notes, dated December 2, 2011 (the “Offering Memorandum”), the Company becomes or will become obligated to pay Additional Amounts as described in
Section 4.8 of the Indenture or (b) any act is taken by a Relevant Taxing Jurisdiction on or after the date of the Offering Memorandum, whether or not such act is taken with respect to the Company or any affiliate, that results in a
substantial probability that the Company will or may be required to pay such Additional Amounts, then the Company may, at its option, redeem the Notes, as a whole but not in part, upon not less than 30











	 	
days’ nor more than 60 days’ published notice in accordance with Section 22 below, at 100% of their principal amount, together with interest accrued thereon to the date fixed for
redemption; provided that the Company determines, in its business judgment, that the obligation to pay such Additional Amounts cannot be avoided by the use of reasonable measures available to the Company (which does not include substitution
of the obligor under the Notes). No redemption pursuant to (a) or (b) above may be made unless the Company has received an opinion of independent counsel to the effect that as a result of such change or amendment the Company will, or that
an act taken by a Relevant Taxing Jurisdiction has resulted in a substantial probability that the Company will, or may, be required to pay the Additional Amounts described in Section 4.8 of the Indenture, and the Company shall have delivered to
the Trustee a certificate, signed by a duly authorized officer, stating that based on such opinion the Company is entitled to redeem the Notes pursuant to their terms. 


 

	 	(7)	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. The
Company will publish a notice of any redemption of Notes in accordance with the provisions described under Section 22 below. The Company will inform the Irish Stock Exchange of the principal amount of the Notes that have not been redeemed in
connection with any redemption. If fewer than all of the Notes are to be redeemed at any time, the Paying Agent will select the Notes to be redeemed in accordance with the rules of the principal securities exchange, if any, on which the Notes are
listed at such time or, if the Notes are not listed on a securities exchange, pro rata, by lot; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Note not redeemed to less
than €100,000. Notes in denominations larger than €100,000 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. 


 

	 	(8)	MANDATORY REDEMPTION. Except as provided in Section 9 below, the Company is not required to make mandatory redemption or sinking fund payments with respect to the
Notes. 

  

	 	(9)	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. 


 

	 	(10)	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. 

  

	 	(11)	 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. 

  

	 	(12)	DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of €100,000 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. 

  

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


 

	 	(14)	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 will be deemed to adversely affect the interests of the Holders of the Notes. 


 

	 	(15)	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. 

  

	 	(16)	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. 

  

	 	(17)	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. 









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


 

	 	(19)	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). 


 

	 	(20)	COMMON CODES AND ISIN NUMBERS. The Company in issuing the Notes may use Common Codes and ISIN numbers (if then generally in use) and, if so, the Trustee shall use
Common Codes and ISIN numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes
or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee and the Paying Agent of any change in the Common Code or ISIN numbers. 

  

	 	(21)	PRESCRIPTION. Claims against the Company for the payment of principal or Additional Amounts, if any, on the Notes will be prescribed for ten years after the applicable
due date for payment thereof. Claims against the Company for the payment of interest on the Notes will be prescribed for five years after the applicable due date for payment of interest. 


 

	 	(22)	NOTICES. All notices to the Holders of Notes shall be valid if published in a manner which complies with the rules and regulations of the Irish Stock Exchange or any
other relevant authority on which the Notes are for the time being listed and so long as the Notes are listed on the Irish Stock Exchange and the guidelines of the Irish Stock Exchange so require, filed with the Companies Announcement Office of the
Irish Stock Exchange. Any such notice will be deemed to have been given on the date of the first publication or, where required to be published in more than one newspaper, on the date of the first publication in all required newspapers. If
publication as provided above is not practicable, notice will be given in such other manner, and shall be deemed to have been given on such date, as the Trustee may approve. Notwithstanding any provision to the contrary, while the Notes are
represented by Global Notes, any notice to the Holders of Notes will be validly given if such notice is delivered to Euroclear and/or Clearstream. Any notice delivered to Euroclear and/or Clearstream will be deemed to be given on the day of
delivery. 

  

	 	(23)	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.

 [REVERSE SIDE OF NOTE] 

5.50% SENIOR NOTES DUE 2026 
 THIS SECURITY IS A GLOBAL SECURITY WITHIN THE MEANING OF THE INDENTURE HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF THE BANK OF NEW YORK DEPOSITORY (NOMINEES) LIMITED, AS NOMINEE FOR THE BANK
OF NEW YORK MELLON, LONDON BRANCH, AS THE COMMON DEPOSITARY (THE “COMMON DEPOSITARY”) FOR EUROCLEAR BANK S.A./N.V. (“EUROCLEAR”) AND CLEARSTREAM BANKING, SOCIÉTÉ ANONYME (“CLEARSTREAM”). THIS
SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE COMMON DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES DESCRIBED IN THE INDENTURE, AND MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE COMMON
DEPOSITARY TO A NOMINEE OF THE COMMON DEPOSITARY, BY A NOMINEE OF THE COMMON DEPOSITARY TO THE COMMON DEPOSITARY OR ANOTHER NOMINEE OF THE COMMON DEPOSITARY OR BY THE COMMON DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF
SUCH A SUCCESSOR DEPOSITARY. 
 THIS SECURITY HAS NOT BEEN AND WILL NOT BE REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS
AMENDED (THE SECURITIES ACT) AND MAY NOT BE OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, UNITED STATES PERSONS EXCEPT IN CERTAIN TRANSACTIONS EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THIS
LEGEND SHALL CEASE TO APPLY UPON THE EXPIRY OF THE PERIOD OF 40 DAYS AFTER THE COMPLETION OF THE DISTRIBUTION OF ALL THE NOTES OF THE SERIES OF WHICH THIS NOTE FORMS PART. 
 UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE COMMON DEPOSITARY, TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS
REGISTERED IN THE NAME OF THE COMMON DEPOSITARY OR IN SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE COMMON DEPOSITARY (AND ANY PAYMENT HEREON IS MADE TO THE COMMON DEPOSITARY OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF THE COMMON DEPOSITARY), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF, THE COMMON DEPOSITARY, 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 5.50% per annum
from December 5, 2011 until maturity. The Company will pay interest in cash annually in arrears on December 7 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 7,
2012; provided further that after December 7, 2012, 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 one Business Day prior to the next succeeding Interest Payment Date, 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 specified office or agency of the Paying Agent in the United Kingdom; provided that payment by wire transfer of immediately available funds will be
required with respect to principal of and interest on all Global Securities registered in the name of or held by a nominee of Euroclear or Clearstream to the account specified by the Holder or Holders thereof; provided, further, that
if certificated Notes are issued, the Company, at its option, may make payments by check mailed to the Holders at their addresses set forth in the register of Holders. Such payment will be in Pounds Sterling. 


 

	 	(3)	PAYING AGENT AND REGISTRAR. Initially, The Bank of New York Mellon, London Branch, 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 December 5, 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)	 REDEMPTION UPON CHANGES IN WITHHOLDING TAXES. If (a) as a result of any change in, or amendment to, the laws (or any regulations or rulings
promulgated thereunder) of the United States (or any political subdivision or taxing authority thereof or therein having power to tax) (a “Relevant Taxing Jurisdiction”), or any change in, or amendment to, the official position
regarding the application or interpretation of such laws, regulations or rulings (including by virtue of a holding, judgment or order by a court of competent jurisdiction or a change in published administrative practice), which change or amendment
is announced on or after the date of the Offering Memorandum related to the Notes, dated December 2, 2011 (the “Offering Memorandum”), the Company becomes or will become obligated to pay Additional Amounts as described in
Section 4.8 of the Indenture or (b) any act is taken by a Relevant Taxing Jurisdiction on or after the date of the Offering Memorandum, whether or not such act is taken with respect to the Company or any affiliate, that results in a
substantial probability that the Company will or may be required to pay such Additional Amounts, then the Company may, at its option, redeem the Notes, as a whole but not in part, upon not less than 30











	 	
days’ nor more than 60 days’ published notice in accordance with Section 22 below, at 100% of their principal amount, together with interest accrued thereon to the date fixed for
redemption; provided that the Company determines, in its business judgment, that the obligation to pay such Additional Amounts cannot be avoided by the use of reasonable measures available to the Company (which does not include substitution
of the obligor under the Notes). No redemption pursuant to (a) or (b) above may be made unless the Company has received an opinion of independent counsel to the effect that as a result of such change or amendment the Company will, or that
an act taken by a Relevant Taxing Jurisdiction has resulted in a substantial probability that the Company will, or may, be required to pay the Additional Amounts described in Section 4.8 of the Indenture, and the Company shall have delivered to
the Trustee a certificate, signed by a duly authorized officer, stating that based on such opinion the Company is entitled to redeem the Notes pursuant to their terms. 


 

	 	(7)	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. The
Company will publish a notice of any redemption of Notes in accordance with the provisions described under Section 22 below. The Company will inform the Irish Stock Exchange of the principal amount of the Notes that have not been redeemed in
connection with any redemption. If fewer than all of the Notes are to be redeemed at any time, the Paying Agent will select the Notes to be redeemed in accordance with the rules of the principal securities exchange, if any, on which the Notes are
listed at such time or, if the Notes are not listed on a securities exchange, pro rata, by lot; provided, however, that no such partial redemption shall reduce the portion of the principal amount of a Note not redeemed to less
than £100,000. Notes in denominations larger than £100,000 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. 


 

	 	(8)	MANDATORY REDEMPTION. Except as provided in Section 9 below, the Company is not required to make mandatory redemption or sinking fund payments with respect to the
Notes. 

  

	 	(9)	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. 


 

	 	(10)	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. 

  

	 	(11)	 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. 

  

	 	(12)	DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of £100,000 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. 

  

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


 

	 	(14)	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 will be deemed to adversely affect the interests of the Holders of the Notes. 


 

	 	(15)	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. 

  

	 	(16)	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. 

  

	 	(17)	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. 









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


 

	 	(19)	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). 


 

	 	(20)	COMMON CODES AND ISIN NUMBERS. The Company in issuing the Notes may use Common Codes and ISIN numbers (if then generally in use) and, if so, the Trustee shall use
Common Codes and ISIN numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes
or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will
promptly notify the Trustee and the Paying Agent of any change in the Common Code or ISIN numbers. 

  

	 	(21)	PRESCRIPTION. Claims against the Company for the payment of principal or Additional Amounts, if any, on the Notes will be prescribed for ten years after the applicable
due date for payment thereof. Claims against the Company for the payment of interest on the Notes will be prescribed for five years after the applicable due date for payment of interest. 


 

	 	(22)	NOTICES. All notices to the Holders of Notes shall be valid if published in a manner which complies with the rules and regulations of the Irish Stock Exchange or any
other relevant authority on which the Notes are for the time being listed and so long as the Notes are listed on the Irish Stock Exchange and the guidelines of the Irish Stock Exchange so require, filed with the Companies Announcement Office of the
Irish Stock Exchange. Any such notice will be deemed to have been given on the date of the first publication or, where required to be published in more than one newspaper, on the date of the first publication in all required newspapers. If
publication as provided above is not practicable, notice will be given in such other manner, and shall be deemed to have been given on such date, as the Trustee may approve. Notwithstanding any provision to the contrary, while the Notes are
represented by Global Notes, any notice to the Holders of Notes will be validly given if such notice is delivered to Euroclear and/or Clearstream. Any notice delivered to Euroclear and/or Clearstream will be deemed to be given on the day of
delivery. 

  

	 	(23)	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.
