Ladies and Gentlemen:

We have acted as special counsel for Celgene Corporation, a Delaware corporation (the “Company”), with respect to the preparation of the Registration Statement on Form S-3 (the “Registration Statement”) filed on October 27, 2016 with the Securities and Exchange Commission (the “Commission”) in connection with the registration by the Company under the Securities Act of 1933, as amended (the “Securities Act”), of the offer and sale by the Company from time to time, pursuant to Rule 415 under the Securities Act, of senior debt securities of the Company. $500,000,000 aggregate principal amount of 2.250% Senior Notes due 2021 (the “Notes”) are being issued by the Company and are being offered and sold by the Company pursuant to the base prospectus forming a part of the Registration Statement, as supplemented by the Prospectus Supplement, dated August 1, 2017 (together, the “Prospectus”), filed by the Company with the Commission pursuant to Rule 424(b) under the Securities Act, and an Underwriting Agreement, dated August 1, 2017 (the “Underwriting Agreement”), among the Company and the underwriter named therein. The Notes will be issued under an Indenture, dated as of August 10, 2017 (the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”).

We have examined: (i) the Registration Statement; (ii) the Prospectus; (iii) the bylaws of the Company as amended and currently in effect; (iv) the Certificate of Incorporation of the Company, as amended and restated and further amended to date; (v) the Indenture; and (vi) such other documents as we have deemed necessary or appropriate for purposes of this opinion.

Based upon and subject to the foregoing, we are of the opinion that, when the Notes have been duly executed, authenticated, issued and delivered in accordance with the terms of the Indenture and the Underwriting Agreement, and upon payment of the consideration therefor or provided for therein, the Notes will constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except as such enforcement may be subject to any applicable bankruptcy, insolvency, reorganization, fraudulent conveyance or other law relating to or affecting creditors’ rights generally and general principles of equity.

The opinion expressed herein is qualified in the following respects:

(1) We have assumed that (i) each document submitted to us for review is accurate and complete, each such document that is an original is authentic, each such document that is a copy conforms to an authentic original and all signatures on each such document are genuine and (ii) each certificate from governmental officials reviewed by us is accurate, complete and authentic, and all official public records are accurate and complete. We have also assumed that the Indenture has been duly authorized, executed and delivered by, and represents a legal, valid and binding obligation of, the Trustee.

(2) This opinion is limited in all respects to laws of the State of New York and the General Corporation Law of the State of Delaware.
