The Securities are to be sold pursuant to the Underwriting Agreement dated March 17, 2020 among the Company and the several underwriters named therein.

I have examined originals or copies of such documents, corporate records, certificates of public officials and other instruments as I have deemed necessary or advisable for the purpose of rendering this opinion.

In rendering the opinion expressed herein, I have, without independent inquiry or investigation, assumed that (i) all documents submitted to me as originals are authentic and complete, (ii) all documents submitted to me as copies conform to authentic, complete originals, (iii) all signatures on all documents that I reviewed are genuine, (iv) all natural persons executing documents had and have the legal capacity to do so, (v) all statements in certificates of public officials and officers of the Company that I reviewed were and are accurate and (vi) all representations made by the Company as to matters of fact in the documents that I reviewed were and are accurate.

Based upon the foregoing, and subject to the additional assumptions and qualifications set forth below, I am of the opinion that:

I am a member of the Bar of the State of Texas, and the foregoing opinion is limited to the New Jersey Business Corporation Act and the federal laws of the United States of America, except that I express no opinion as to any law, rule or regulation that is applicable to the Company, the Documents or such transactions solely because such law, rule or regulation is part of a regulatory regime applicable to any party to any of the Documents or any of its affiliates due to the specific assets or business of such party or such affiliate.

Davis Polk & Wardwell LLP, special counsel to the Company, may rely upon this opinion in rendering its opinion of even date herewith.

I hereby consent to the filing of this opinion as an exhibit to a current report on Form 8-K to be filed by the Company on the date hereof and its incorporation by reference into the Registration Statement and further consent to the reference to my name under the caption “Validity of the Notes” in any prospectus supplement relating to the Securities which is a part of the Registration Statement.
