LLC, Deutsche Bank Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representatives of the several underwriters named in Schedule I thereto, relating to the proposed public offering of $1,000,000,000 aggregate principal amount of the Company’s 1.500% Notes due 2019 (the “2019 Notes”), $1,000,000,000 aggregate principal amount of the Company’s 2.100% Notes due 2022 (the “2022 Notes”), $2,000,000,000 aggregate principal amount of the Company’s 2.900% Notes due 2027 (the “2027 Notes”) and $1,000,000,000 aggregate principal amount of the Company’s 3.750% Notes due 2047 (together with the 2019 Notes, the 2022 Notes and the 2027 Notes, the “Securities”) pursuant to the Company’s automatic shelf registration statement on Form S-3ASR (Reg. No. 333-210983) (the “Registration Statement”), filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), on April 28, 2016. This opinion letter is furnished to you at your request to enable you to fulfill the requirements of Item 601(b)(5) of Regulation S-K, 17 C.F.R. § 229.601(b)(5), in connection with the Registration Statement.

This opinion letter is based as to matters of law solely on the applicable provisions of the following, as currently in effect: (i) the General Corporation Law of the State of California, as amended, and (ii) the laws of the State of New York (but not including any laws, statutes, ordinances, administrative decisions, rules or regulations of any political subdivision below the state level). We express no opinion herein as to any other laws, statutes, ordinances, rules, or regulations (and in particular, we express no opinion as to any effect that such other laws, statutes, ordinances, rules, or regulations may have on the opinions expressed herein).

For purposes of this opinion letter, we have assumed that (i) The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”) under the Indenture, dated as of April 29, 2013, between the Company and the Trustee, filed as Exhibit 4.1 to the Registration Statement (the “Base Indenture”), as supplemented by the Officer’s Certificate, dated September 12, 2017, filed as Exhibit 4.1 to the Company’s Form 8-K filed with the Commission on September 12, 2017 (the “Officer’s Certificate” and, together with the Base Indenture, the “Indenture”) has all requisite power and authority under all applicable laws, regulations and governing documents to execute, deliver and perform its obligations under the Indenture and has complied with all legal requirements pertaining to its status as such status relates to the Trustee’s right to enforce the Indenture against the Company, (ii) the Trustee has duly authorized, executed and delivered the Indenture, (iii) the Trustee is validly existing and in good standing in all necessary jurisdictions, (iv) the Indenture constitutes a valid and binding obligation, enforceable against the Trustee in accordance with its terms, (v) there has been no mutual mistake of fact or misunderstanding or fraud, duress or undue influence in connection with the negotiation, execution or delivery of the Indenture, and the conduct of all parties to the Indenture has complied with any requirements of good faith, fair dealing and conscionability, (vi) at the time of offer, issuance and sale of any Securities, the Registration Statement will have been declared effective under the Act and no stop order suspending its effectiveness will have been issued and remain in effect and (vii) there are and have been no agreements or understandings among the parties, written or oral, and there is and has been no usage of trade or course of prior dealing among the parties that would, in either case, define, supplement or qualify the terms of the Indenture. We also have assumed the validity and constitutionality of each relevant statute, rule, regulation and agency action covered by this opinion letter.

Based upon, subject to and limited by the foregoing, we are of the opinion that the Securities have been duly authorized on behalf of the Company and that, following (i) receipt by the Company of the consideration for the Securities specified in the Underwriting Agreement and (ii) the due execution, authentication, issuance and delivery of the Securities pursuant to the terms of the Indenture, the Securities will constitute valid and binding obligations of the Company.

The opinion expressed above with respect to the valid and binding nature of obligations may be limited by bankruptcy, insolvency, reorganization, receivership, moratorium or other laws affecting creditors’ rights (including, without limitation, the effect of statutory and other law regarding fraudulent conveyances, fraudulent transfers and preferential transfers) and by the exercise of judicial discretion and the application of principles of equity, good faith, fair dealing, reasonableness, conscionability and materiality (regardless of whether the Securities are considered in a proceeding in equity or at law).

This opinion letter has been prepared for use in connection with the filing by the Company of a Current Report on Form 8-K on the date hereof, which Form 8-K will be incorporated by reference into the Registration Statement and speaks as of the date hereof. We assume no obligation to advise you of any changes in the foregoing subsequent to the delivery of this opinion letter.
