     WHEREAS, HARRIS CORPORATION (the “Company”) and THE NORTHERN TRUST COMPANY, an Illinois corporation of Chicago, Illinois (the “Trustee”), executed the Harris Corporation Master Rabbi Trust Agreement (The “Trust”), effective the 2nd day of December, 2003; and

     NOW, THEREFORE, the section of the Trust set forth below is amended as follows, but all other sections of the Trust shall remain in full force and effect.

1. Section 5(c) shall be amended by adding the following new paragraph to the end thereof:

     “The Company shall have the sole investment responsibility with respect to the retention, sale, purchase or voting of any common stock of the Company (“Employer Stock”) which has not been allocated to an Investment Manager. The Trustee shall have custody of such Employer Stock and shall act with respect thereto only as directed by the Company. The Trustee shall not make any investment review of, consider the propriety of holding or selling, or vote any such Employer Stock. Except for the short term investment of cash, the Company has limited the investment power of the Trustee with respect to the account containing the Employer Stock. The Trustee shall not be liable for the purchase, retention, voting, tender, exchange or sale of Employer Stock and the Company (which has the authority to do so under the laws of the state of its incorporation) agrees to indemnify THE NORTHERN TRUST COMPANY from any liability, loss and expense, including legal fees and expenses which THE NORTHERN TRUST COMPANY may sustain by reason of purchase, retention, voting, tender, exchange or sale of Employer Stock. This paragraph shall survive the termination of this agreement.”
