Re: Employment by Harris Corporation

Dear Howard,

Regarding your employment by Harris Corporation (the “Corporation”), we have agreed as follows:

1. The Executive Employment Agreement between you and the Corporation dated January 20, 2003 and all obligations under that agreement will expire and be of no further force and effect on January 19, 2005.

2. After January 19, 2005 the terms of your employment will be governed by the terms of this letter agreement which shall have an indefinite term subject to amendment or termination on one year written notice by either you or a representative of the Harris Corporation Board of Directors.

3. During the Term of Employment (as defined below), and subject to Section 4 below, you shall serve as Chief Executive Officer, President, a Director, and Chairman of the Board, subject to the Corporation’s succession and retirement practices upon your attaining of the age of sixty-five in the case of a Chief Executive Officer. During the Term of Employment you agree to devote your full and exclusive business and working time, skill, attention, and energy diligently to perform the duties assigned to you by the Corporation’s Board of Directors. Notwithstanding the preceding obligation, you are permitted to join up to two public-company boards provided they have no conflict of interest and do not compete with the Corporation. For purposes of this agreement, “Term of Employment” shall mean the period starting January 20, 2005 and ending on the termination of your employment as set forth in Section 4.

4. Your employment may be terminated as follows: (1) by the Corporation with or without Cause (as defined below); (2) upon your Death; (3) upon your Disability (as defined below); (4) upon your resignation for Good Reason (as defined below), or (5) upon your resignation or retirement.

a. Termination for Cause: In order to terminate your employment for Cause, the Corporation must deliver to you at your office address a Notice of Termination given within ninety (90) days after the Board both (i) has actual knowledge of

conduct or an event allegedly constituting Cause, and (ii) has reason to believe that such conduct or event could be grounds for Cause. For purposes of this letter agreement a “Notice of Termination” shall mean a copy of a resolution duly adopted by the affirmative vote of not less than a majority of the membership of the Board, excluding you, at a meeting called for the purpose of determining that you have engaged in conduct which constitutes Cause (and at which you had a reasonable opportunity, in consultation with your counsel, to be heard before the Board prior to such vote).

For purposes of this letter agreement “Cause” shall have the meaning set forth in Section 1(b)(1) and (2) of the Severance Agreement between you and the Corporation dated January 20, 2003 and “Cause” shall also include a breach of this letter agreement by you.

In the event of termination of your employment by the Corporation for Cause, you shall only be entitled to:

(i) any accrued but unpaid Base Salary (as defined by a resolution of the Board of Directors) through your date of termination;

(ii) any earned but unpaid annual incentive bonus under the Corporation’s Annual Incentive Plan or the successor to such plan (referred to herein as the “AIP”) for the prior fiscal year;

(iii) reimbursement of reasonable business expenses incurred prior to the date of termination; and

(iv) other or additional compensation benefits, if any, in accordance with the terms of applicable plans or employee benefit programs of the Corporation for terminated employees, including the terms and conditions governing stock options, performance shares and restricted stock.

b. Death or Disability. In the event of your Death or Disability your employment shall be automatically terminated as of the date of such Death or determination of Disability and you, or your estate or legal representative, as appropriate, shall be entitled to the amounts referred to in paragraph a. of this Section 4 for employees that die or become disabled.

For purposes of this letter agreement, “Disability” shall mean that you qualify for long-term “disability” in the Long-Term Disability Plan sponsored by the Corporation in which you participate at the time the determination of Disability is made.

c. Termination by Corporation Without Cause or by you for Good Reason. If the Corporation should terminate your employment without Cause, (which the Corporation shall be entitled to do upon thirty (30) days prior written notice), or in the event you terminate employment for Good Reason, your exclusive compensation and remedy hereunder shall be to receive from the Corporation:

(i) continuation of Base Salary for a period of two years;

(ii) AIP bonus for the year of termination as approved by the Board, pursuant to the Corporation’s policy for prorating such award for retiring employees;

(iii) without duplication, the amounts referred to in paragraph a. (i) — (iv) of this Section 4;

(iv) continued participation in the medical, dental, hospitalization, short-term and long-term disability, and group life insurance coverage plans of the Corporation (“Welfare Plans”) in which you were participating on the date of the termination of your employment until the earlier of:

(a) the end of the 24-month period following your termination of employment; and

(b) the date, or dates, you receive comparable coverage and benefits under the plans and programs of a subsequent employer;

provided, however, if under terms of any such Welfare Plan you cannot continue to participate in the Corporation’s Welfare Plans, the Corporation shall otherwise provide such benefits on the same after-tax basis as if continued participation had been permitted; and provided further, however, nothing herein shall be deemed to limit any amounts or benefits to which you are otherwise entitled under the terms of or pursuant to COBRA;

(v) during such two year period and notwithstanding the terms and conditions of the restricted stock or stock option agreements, pursuant to the Harris Corporation 2000 Stock Incentive Plan (referred to herein as the “SIP”), continued vesting of such restricted stock or options in accordance with the relevant anniversary dates; and, as to vested stock options, exercisable on or before three months after such two year period, provided however, continued compliance with your obligations of non-competition and non-solicitation as specified in Sections 5 and 6, respectively, is a condition of such continued vesting. In the event you breach your non-competition and non-solicitation obligations, in addition to any other remedies available to the Corporation, such vesting shall cease.

(vi) prorated vesting of outstanding performance share awards pursuant to the Corporation’s SIP and SIP performance targets and resultant performance as approved by the Board, pursuant to the Corporation’s existing polices for prorating such awards for retiring employees; and

(vii) outplacement services at the Corporation’s expense for a period of up to one year following the date of termination of employment in accordance with the practices of the Corporation as in effect from time to time for senior executives.

You must, within ninety (90) days after you have actual knowledge of the occurrence of an event or circumstances which would give your reason to believe constitutes Good Reason, give thirty (30) days prior written notice of your intent to terminate employment for Good Reason which notice sets forth the event or circumstances believed to constitute Good Reason. Upon receipt of such notice, the Corporation shall have thirty (30) days to cure its conduct, to the extent such cure is possible.

d. For purposes of this letter agreement, “Good Reason” shall mean any of the following (without your express written consent):

(i) a reduction in the amount of your then current Base Salary or target AIP, other than any reduction that is also applicable to the other senior executives of the Corporation;

(ii) the removal of, or failure to elect or reelect you as President or Chief Executive Officer or Chairman of the Board of the Corporation provided however, (1) the failure to elect you as Chairman of the Board shall not constitute Good Reason if such failure results from any law, regulation or listing requirement to the effect that the positions of Chairman of the Board and Chief Executive Officer shall not be held by the same individual or that the Chairman of a Corporation shall be independent; and (2) the failure to elect you as President if necessary for purposes of succession planning for your successor;

(iii) the assignment to you of duties or responsibilities which are materially inconsistent with your position;

(iv) any requirement by the Corporation that you relocate to Corporation headquarters which are more than 50 miles from where such headquarters are located as of the date of this letter; and

(v) notice of any amendment of Section 4.c. and 4.d. or termination by the Board of Directors of this agreement under Section 2 without your prior written consent.

e. Termination without Good Reason. In the event of a termination of employment by you without Good Reason (other than a termination due to Death or Disability), you shall have the same entitlements as provided in paragraph a. of this Section 4 for termination for Cause.

5. During your employment with the Corporation and for a period of one year (or a period of two years if you are receiving severance compensation from the Corporation) after the date your employment is terminated for whatever reason, you will not directly or indirectly (without the Corporation’s written consent):

a. hold a 5% or greater equity (including stock options whether or not exercisable), voting or profit participation interest in a Competitive Enterprise (as hereinafter defined), or

b. associate (including as a director, officer, employee, partner, consultant, agent or advisor) with a Competitive Enterprise and in connection with your association

(ii) that is substantially related to any activity for which you had direct or indirect managerial or supervisory responsibility with the Corporation or its affiliates during the 12 months prior to the date of termination, or

(iii) that calls for the application of specialized knowledge or skills substantially related to those used by you in your activities with the Corporation or its affiliates during the 12 months prior to the date of termination.

For purposes of this letter agreement, “Competitive Enterprise” means any business enterprise that either (A) engaged in any activity that competes anywhere with any activity that the Corporation or its affiliates is then engaged in or (B) holds a 5% or greater equity, voting or profit participation interest in any enterprise that engages in such a competitive activity.

6. During your employment with the Corporation, and for a two year period after your employment is terminated by the Corporation or by you for any reason, you shall not, in any manner, directly or indirectly (without the prior written consent of the Corporation: (i) Solicit (as hereinafter defined) any Customer (as hereinafter defined) to transact business with a Competitive Enterprise or to reduce or refrain from doing any business with the Corporation, (ii) transact business with any Customer that would cause you to be a Competitive Enterprise, (iii) interfere with or damage any relationship between the Corporation and a Customer or (iv) Solicit anyone who is then an employee of the Corporation (or who was an employee of the Corporation within the prior 12 months) to resign from the Corporation or to apply for or accept employment with any other business or enterprise.

7. In the event your employment is terminated for other than Cause, you shall not be required to mitigate any payment or benefits provided to you by the Corporation by seeking other employment.

8. In the event of a change in control of the Corporation (as defined in the Executive Severance Agreement dated January 20, 2003), you shall be entitled to the compensation and benefits provided under the Executive Severance Agreement if your employment terminates under the circumstances provided under the Executive Severance Agreement provided, however, such compensation and benefits shall be in lieu of any compensation or benefits receivable by you under this letter agreement.

9.
