(e) On April 26, 2010, Amgen Inc. (the “Company”) publicly announced the decision of George J. Morrow, 58, Executive Vice President, to retire from the Company, effective January 31, 2011. On October 20, 2010, the Company and Mr. Morrow entered into a one-year consulting services agreement, effective as of February 1, 2011, between Mr. Morrow and the Company (the “Consulting Agreement”), with the option to extend the agreement for a second year by mutual agreement. Pursuant to the Consulting Agreement, Mr. Morrow will advise the Company on issues related to his areas of expertise, including commercialization of the R&D product pipeline, product launches and related areas (the “Services”). The Company will pay Mr. Morrow $100,000 quarterly in arrears (the “Consulting Fee”) as compensation for 80 hours of Services in a quarter, plus an additional $1,200 per hour for any additional hours of Services performed in any quarter (up to a maximum of 80 additional hours per quarter). The maximum total hours of Services in any quarter shall be 160 hours unless previously authorized by the Senior Vice President, Human Resources or his designee. If Mr. Morrow provides less than 80 hours of Services in any quarter, the Consulting Fee paid by the Company for the next quarter shall entitle the Company to 80 hours of Services plus the hours of any shortfall from prior quarters. In addition, upon advance written approval, the Company will reimburse Mr. Morrow for all reasonable and normal travel-related expenses incurred in connection with the Services, including automobile rental and other transportation expenses and hotel expenses, other than travel to the Company’s Thousand Oaks facility. Mr. Morrow will be solely responsible for the income and self-employment taxes due on all taxable income arising under the Consulting Agreement. Pursuant to the Consulting Agreement, Mr. Morrow agrees not to accept any employment or other consulting arrangement that would present a conflict of interest during the term of the Consulting Agreement. If Mr. Morrow accepts employment or an engagement which the Company determines, in its sole discretion, presents a conflict of interest, Mr. Morrow’s acceptance shall constitute a material breach of the Consulting Agreement and authorize the Company to terminate the Consulting Agreement immediately. Either Mr. Morrow or the Company can terminate the Consulting Agreement for any reason on 30 days notice.

A copy of the Consulting Agreement is filed as Exhibit 10.1 to this Current Report on Form 8-K.
