Dear Lori:


On behalf of Amgen, I am pleased to offer you the position of SVP Human Resources, Level 10, reporting to Robert A. Bradway. This offer and the compensation listed are subject to your appointment by our Board of Directors (the Board) and the Compensation and Management Development Committee (the Compensation Committee) providing final approval of the compensation listed in this letter.


Your salary will be paid bi-weekly in the amount of $25,000.00, with 26 pay periods in one year, less federal and state tax deductions and other applicable deductions and withholdings.


Provided that you sign a “Sign-On/Retention Bonus Agreement for New Hire Staff Members” in the form provided by Amgen, you will be eligible to earn a bonus of $2,000,000.00, less federal and state tax deductions and other applicable deductions and withholdings, subject to the terms of that Agreement. Please review that Agreement for information regarding timing and other payment details.


You will be granted time-vested restricted stock units (RSUs) valued at $800,000.00. The actual number of RSUs will be determined by dividing $800,000.00 by the closing price of Amgen common stock on the expected grant date occurring 2 business days after the release of Amgen’s fourth quarter 2016 earnings release, currently anticipated to be February 1, 2017, providing you are actively employed on that date. Upon each applicable vesting date, you will receive a number of shares of Amgen common stock equal to the number of restricted stock units that vest, less any shares that are withheld to satisfy applicable taxes. This grant will vest beginning with the first anniversary of the grant date through the fourth anniversary of the grant date at a rate of 25% each year, respectively, contingent upon your being actively employed by Amgen through each vesting date.


Restricted stock units will be subject to the terms and conditions set forth in the applicable grant agreement.


In addition, beginning in 2017, you will be eligible to receive additional grants as part of Amgen’s Long Term Incentive (LTI) program. Grants under the LTI program are discretionary as approved by the Compensation Committee.


You will be eligible to participate in Amgen’s Global Management Incentive Plan (the “GMIP”) pursuant to the terms of the GMIP. Your annual target incentive opportunity will be 80% of your base salary earnings during the plan year. Awards under the GMIP are discretionary. Your actual GMIP bonus may be more or less than this target amount, and may vary based on Company performance, any other criteria selected by the Company, and management’s assessment of your individual performance and contribution. You must be actively employed through the last regularly scheduled Amgen business day of the plan year to be eligible for that year’s GMIP bonus.


You are also eligible to participate in the Amgen Nonqualified Deferred Compensation Plan (the “DCP”) to voluntarily defer, on a pre-tax basis, a portion of your annual earnings, including base salary, commissions, and/or GMIP bonus. Shortly after commencing your employment at Amgen, you will receive an enrollment e-mail regarding the DCP plan for Amgen. A Q&A regarding the DCP will be provided to you.


Amgen will credit $2,300,000.00 on your behalf to the DCP as a “Company Contribution Amount” (as defined in the DCP). Your $2,300,000.00 Company Contribution Amount will vest as follows, contingent on your employment at each vesting date:


33% on the 1st anniversary of the date of your employment with Amgen and its subsidiaries.
33% on the 2nd anniversary of the date of your employment with Amgen and its subsidiaries.    
34% on the 3rd anniversary of the date of your employment with Amgen and its subsidiaries.


Upon vesting, each portion of the contribution plus any gains or losses is subject to FICA and will be withheld as soon as possible from your next available payroll check.


This credit, plus any credited earnings (or minus any losses) will be paid to you after your “Separation from Service” (as defined in the DCP) in accordance with the terms of the DCP. Generally, Separation from Service means the termination of your employment

with Amgen and its subsidiaries. Please note that Company contributions are not eligible for the Short-Term Payout provision of the DCP.


In addition, your position will make you eligible to participate in the Amgen Inc. Change of Control Severance Plan, as amended from time to time (the “COC”) as a Group I Participant according to the terms of the COC. COC eligibility and benefit levels are determined immediately prior to a “Change of Control” as defined in the COC. If, upon your termination, you are eligible to receive severance benefits under the COC and you are also eligible to receive severance benefits from another plan agreement or other source, you will be paid the greater of the amount from that plan or the amount provided in the COC, but not both amounts. A copy of the COC will be provided to you.


If, within the first 3 years of your employment with Amgen, Amgen terminates your employment without “Cause”, as defined below, you will be entitled to the benefits described in this paragraph (the “Termination Paragraph), provided that you sign a general release in the form furnished to you by Amgen and do not timely revoke it. The following are such benefits: two (2) times the sum of your annual base salary, then in effect, and target cash incentive opportunity (i.e., GMIP or successor bonus plan target, which is currently 80%), then in effect, paid in a lump sum as soon as administratively practicable, but in no event later than March 15 of the year following the year in which Amgen terminates your employment and (2) if you elect continuation coverage under the Amgen group medical and dental plans for yourself and your qualified beneficiaries under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), Amgen will pay the cost of such coverage until the earlier to occur of the following: (A) eighteen (18) months following your termination of employment or (B) the date on which you are no longer eligible for such COBRA coverage. Please note that this Termination Paragraph does not alter the at-will nature of your employment at Amgen. 


For purposes of the Termination Paragraph, “Cause” means: (i) unfitness for service, inattention to or neglect of duties, or incompetence; (ii) dishonesty; (iii) disregard or violation of the policies or procedures of Amgen; (iv) refusal or failure to follow lawful directions of Amgen; (v) illegal, unethical or immoral conduct; (vi) breach of Amgen’s Proprietary Information and Inventions Agreement entered into by you; or (vii) any other reason set forth in California Labor Code Section 2924, in all cases, as determined by Amgen.


As an executive at Amgen, you will be eligible for the following: an annual physical examination provided by Amgen; and, reimbursement for up to $15,000.00, less federal and state tax deductions and other applicable deductions and withholdings, for financial counseling, tax preparation and related services. This value will be treated as imputed income for purposes of tax treatment.


You will also have the opportunity to participate in our comprehensive benefits program. Amgen’s excellent health care plan currently includes medical, dental, and vision coverage for you and your eligible dependents. Amgen currently pays the major expense for these programs while staff members share through payroll deductions. Please be advised that in order for you and your dependents to be eligible for Amgen’s medical coverage you must:


		
	1.
	Report to work at Amgen or another location to which you are required to travel and perform the regular duties of your employment.


		
	2.
	Contact the Amgen Benefits Center at 1-800-97AMGEN, to enroll within 31 days of your hire date.


		
	3.
	Meet all other eligibility requirements under the plan.




The Amgen Retirement and Savings Plan, our 401(k) plan, provides an opportunity for you to save a percentage of your pay (based on Internal Revenue Service limits) on a tax-deferred basis. Amgen will also contribute to your 401(k) account to help you save for your future financial goals. These benefits, services and programs are summarized in the enclosed brochure called “A Guide to Total Rewards at Amgen.”


This offer of employment is contingent upon confirmation by Amgen of information listed on your employment application, and the receipt by Amgen of satisfactory results from a background verification and pre-employment drug test. Your drug test will be scheduled as soon as practicable following your acceptance of this offer.


Enclosed and included as part of this offer is information regarding Amgen's Proprietary Information and Inventions Agreement, the Immigration Reform & Control Act, and a packet of materials entitled "Arbitration of Disputes" which includes a Mutual Agreement to Arbitrate Claims.

This offer is contingent upon you truthfully and accurately completing the Certification, and returning it to the Company before your first day of employment.


This offer of employment is contingent upon your completing the items described in Attachment 1, and upon your ability to perform for Amgen all of the duties of your position without restriction from, or violation of, any enforceable contractual obligations owed to any former employer or entity for whom you worked or provided service(s).

Also enclosed and included, as part of this offer (Offer Letter Benefit Summary), is information about the main points of the relocation assistance that Amgen will provide to you to relocate to the “local area.” Please note that relocation assistance is contingent upon your execution of the enclosed “Amgen Relocation Agreement for New Hire Staff Members,” subject to the terms of that Agreement, and that relocation benefits are limited to one benefits package per household.


You will be contacted by a Relocation Counselor to initiate your relocation benefits within 7 business days after receipt of your signed acceptance of this offer and your signed New Hire Relocation Agreement.

AMGEN SIGN-ON/RETENTION BONUS AGREEMENT
FOR NEW HIRE STAFF MEMBERS




I, Lori A. Johnston, agree to accept my sign-on/retention bonus payment (“Bonus”) from Amgen on the following terms.


		
	1.
	The amount of the Bonus is described in the offer letter (as may be amended) that was provided separately to me.




		
	2.
	The Bonus will generally be paid to me as follows:




		
	•
	Within thirty (30) days following my start date with Amgen, I will be paid $2,000,000.00 as a Bonus. This amount will be earned only after I complete two years of employment with Amgen. The Bonus is intended to facilitate my acceptance of employment with Amgen and my continued employment with Amgen for a period of at least two years. Amgen is providing me with the Bonus with the expectation that I will not resign my employment during this two-year period.




		
	3.
	I understand and agree that I am an at-will employee and that I am free to resign at any time and Amgen is free to terminate my employment, with or without cause, at any time. Nevertheless, I understand that if I resign my employment with Amgen or if Amgen terminates my employment for Cause as defined in my Offer Letter before I complete two years of employment, I have not earned any portion of the Bonus amount. Therefore, I agree to repay Amgen for the gross amount of my Bonus advance if I resign my employment for any reason or if Amgen terminates my employment for Cause within 24 months from my hire date at Amgen. I also agree that in the event of such a resignation, the amount to be repaid shall be due in full and payable by me immediately in cash (i.e., by check, wire transfer, or similar immediate payment) without further notice or demand by Amgen.




		
	4.
	Generally, a sign-on/retention bonus is considered ordinary wage income to the recipient. I understand that Amgen will report to appropriate federal and state taxing authorities all income that Amgen considers to be subject to taxation and will withhold appropriate taxes in accordance with federal and state regulations. I understand that it is my obligation to declare all income and pay all taxes owed on such income, if any. I also understand that this Bonus payment is not considered eligible earnings for annual incentive (bonus) purposes.




		
	5.
	I understand that this agreement shall be governed by the law of the State of California.




		
	6.
	Nothing in this Agreement will be construed as an employment contract or to guarantee me employment at Amgen for any fixed term. I understand that my employment at Amgen is at will.




		
	7.
	The provisions of this agreement are severable. If any part is found to be unenforceable, all other provisions shall remain fully valid and enforceable.

AMGEN RELOCATION AGREEMENT
FOR NEW HIRE STAFF MEMBERS


I, Lori A. Johnston, agree to accept certain relocation benefits from Amgen on the following terms.


		
	1.
	The relocation benefits to be provided to me are outlined in the Amgen Relocation Policy that applies to staff members at my Global Career Framework (“GCF”) level. 




		
	2.
	I will obtain relocation benefits from Amgen by following the procedures outlined in the Amgen Relocation Policy that applies to staff members at my GCF level.




		
	3.
	I understand that I may obtain an estimate of my relocation costs from Amgen/Amgen’s third-party relocation vendor and that the actual cost of my relocation may be more or less than the estimate I am provided. I further understand that I can obtain detailed information about the actual services and costs being incurred during my relocation by contacting Amgen or Amgen’s third-party relocation vendor.




		
	4.
	The relocation benefits are to facilitate my move as a result of my decision to accept an offer of employment with Amgen. I acknowledge that the cost of these benefits is not required to be reimbursed to me as a matter of law under California Labor Code section 2802 or any similar statute.




		
	5.
	Amgen provides the relocation benefits with the expectation that I will not in the short term resign my employment. While, as an at-will employee, I am free to resign at any time, I agree to reimburse Amgen for the gross amount of the cost of the relocation benefits (according to the schedule below) if I resign my employment for any reason within 730 days of my start date with Amgen. Upon my resignation, the amount to be reimbursed shall be immediately due and payable by me without further notice or demand. The schedule for reimbursement is as follows:


	
		
	Days Since Start Date
	% of Gross Cost of Relocation Benefits to be
Reimbursed to Amgen

	0 to 365 days
	100 %

	366- 450 days
	  75 %

	451 - 540 days
	  50 %

	541 - 730 days
	  25 %

	Over 730 days
	    0 %






		
	6.
	I understand that Amgen will report to federal and state taxing agencies all income that Amgen considers to be subject to taxation. I understand that it is my obligation to declare all income and pay all taxes owed on such income, if any.




		
	7.
	In the event that I fail to make a reimbursement required by this agreement and Amgen initiates proceedings to recover such reimbursement, the prevailing party in such a suit shall be awarded its reasonable costs and attorney’s fees.




		
	8.
	I understand that this agreement shall be governed by the law of the State of California.




		
	9.
	Nothing in this agreement will be construed as an employment contract or to guarantee me employment at Amgen for any fixed term. I understand that my employment at Amgen is at will. Nor does this agreement guarantee me reimbursement of any particular relocation expenses. I understand that reimbursement is governed by the Amgen Relocation Policy and that I must comply with the procedures in that policy.




		
	10.
	The provisions of this agreement are severable. If any part is found to be unenforceable, all other provisions shall remain fully valid and enforceable.
