                  WHEREAS, Harris Corporation, a Delaware corporation (the

          3. Section 5.2 of the Plan is amended to add the following new
subsection (b) immediately after subsection (a) and the remaining subsections of
Section 5.2 shall be relettered appropriately:

               (b) Harris Stock. If the Harris Stock Fund is designated by the
          Committee as an investment fund hereunder, then Participants who are
          not participants in the Retirement Plan may not direct the investment
          of their Accounts to reflect the performance of the Harris Stock Fund.
          The special rules set forth in Section 8.2(c) of the Retirement Plan
          applicable to the Harris Stock Fund relating to availability,
          restrictions on transfer, and dividends shall apply to amounts deemed
          invested in the Harris Stock Fund under this Plan. If a Participant
          who is a director or officer of the Corporation within the meaning of
          Rule 16a-1(f) under Section 16 of the Securities Exchange Act of 1934
          and who is a participant in the Retirement Plan elects to have his or
          her Account credited with earnings and losses experienced by the
          Harris Stock Fund, then, unless otherwise directed by the Committee
          with respect to all such directors and officers, amounts credited
          during any calendar quarter to such Participant's Account pursuant to
          the Participant's election to have such amounts deemed invested in the
          Harris Stock Fund shall be an election to have the amounts deemed to
          be invested in the Stable Value Fund (or such other investment fund
          designated by the Committee) until the first day of the following
          calendar quarter and on such day shall be deemed to be invested in the
          Harris Stock Fund.

          4. Section 5.2(c) (as relettered by this amendment) is amended to add
the following words at the end of the first sentence thereof:

          , except that in the case of a Participant who is a director or
          officer of the Corporation within the meaning of Rule 16a-1(f) under
          Section 16 of the Securities Exchange Act of 1934 who had elected to
          have a portion of his or her Account deemed to be invested in the
          Harris Stock Fund prior to June 1, 2003, such Participant's investment
          election shall be modified to provide the temporary investment in the
          Stable Value Fund as described in Section 5.2(b).

          APPROVED by the members of the HARRIS CORPORATION MANAGEMENT
DEVELOPMENT AND COMPENSATION COMMITTEE and by the BOARD OF DIRECTORS on this
25th day of April, 2003.
