On March 5, 2021, the Company issued and sold $450,000,000 principal amount of its 1.75% Senior Notes due 2028 (the “Notes”) under an Indenture, dated as of December 1, 2001, between the Company and The Bank of New York Mellon Trust Company, N.A. (as successor to The Bank of New York), as trustee (the “Trustee”), as amended and supplemented (the “Indenture”).

In connection with the issuance and sale of the Notes by the Company, we have reviewed originals (or copies certified or otherwise identified to our satisfaction) of (1) the Registration Statement; (2) a prospectus dated October 14, 2020 (the “Base Prospectus”) forming a part of the Registration Statement, as supplemented by a prospectus supplement dated February 24, 2021 (the “Prospectus Supplement”) relating to the Notes, both such Base Prospectus and Prospectus Supplement filed pursuant to Rule 424 under the Securities Act; (3) the Company’s Restated Articles of Incorporation, as amended, and By-Laws, as amended, each as in effect on the date hereof; (4) the Indenture; (5) a specimen of the Notes; and (6) corporate and other documents, records and papers and certificates of public officials. In addition, we have reviewed such other documents and materials as we have deemed necessary or appropriate for purposes of this opinion. In connection with such review, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the conformity to the originals of the documents submitted to us as certified or photostatic copies, the authenticity of the originals of such documents and all documents submitted to us as originals and the correctness of all statements of fact contained in such original documents. We have relied upon a certificate of the Trustee as to the authentication and delivery of the Notes under the Indenture.

On the basis of such review, we are of the opinion that the Notes are valid and binding
