Re:      HARRIS CORPORATION RETIREMENT PLAN
         -- REGISTRATION STATEMENT ON FORM S-8
         -----------------------------------------------------------

Ladies and Gentlemen:

         I am Vice President - Counsel, Corporate & Commercial Operations of
Harris Corporation, a Delaware corporation ("Harris"), and in such capacity have
acted as counsel for Harris in connection with the proposed registration under
the Securities Act of 1933, as amended, of up to 1,500,000 shares of Harris'
Common Stock, par value $1.00 per share (the "Shares"), which may be issued by
Harris pursuant to the Harris Corporation Retirement Plan (the "Plan").

         In connection therewith, I have examined such corporate records and
other documents and instruments, including the Registration Statement on Form
S-8 relating to the Shares (the "Registration Statement"), as I have deemed
necessary to express the opinions contained herein. In the examination of such
documents and instruments, I have assumed the genuineness of all signatures and
the authenticity of all documents submitted to me as originals and the
conformity to those original documents of all documents submitted to me as
certified or photostatic copies.

         I am admitted to the Bars of the States of New York and Florida. The
opinions expressed herein are limited in all respects to the Federal laws of the
United States of America and the General Corporation Law of the State of
Delaware.

         On the basis of the foregoing examination and review, I am of the
opinion that:

         1. Harris is a corporation duly incorporated and validly existing under
the laws of the State of Delaware.

         2. The Shares have been duly authorized by all necessary corporate
action on the part of Harris and, when issued in accordance with the terms of
the Plan as original issuance shares, and upon receipt of consideration
therefore in accordance with the terms of the Plan, will be validly issued,
fully paid and non-assessable.

any person or entity for any purpose without my prior written consent.

         I hereby consent to the filing of this opinion with the Securities and
Exchange Commission as an exhibit to the Registration Statement. In giving this
consent, I do not admit that I am in the category of persons whose consent is
required under Section 7 of the Securities Act of 1933 or the rules and
regulations of the Securities and Exchange Commission thereunder.

                                        Very truly yours,
