                  WHEREAS, Harris Corporation, a Delaware corporation (the
"Corporation"), has heretofore adopted and maintained the Harris Corporation
Retirement Plan, as amended and restated effective January 1, 2003 (the "Plan");

                  include the first twelve months of absence from employment,
                  effective as of the date of such termination of employment."

                  2. Effective March 28, 2005, Section 9.4 of the Plan is hereby

                  "In the event of a mandatory distribution greater than $1,000

                  have such distribution paid as a direct rollover pursuant to
                  Section 9.6 or to receive the distribution directly, then the

                  individual retirement plan designated by the Administrative
                  Committee."

         Section 13.10. Limitations on Investments and Transactions/Conversions.
Notwithstanding any provision of the Plan to the contrary:

<PAGE>

         (a) The Employee Benefits Committee, in its sole and absolute
discretion, may temporarily suspend, in whole or in part, certain Plan
transactions, including, without limitation, the right to change or suspend
contributions and/or the right to receive a distribution, loan or withdrawal
from an Account in the event of any conversion, change in recordkeeper, change
in investment funds and/or Plan merger or spinoff.

         (2) The Employee Benefits Committee, in its sole and absolute
discretion, may suspend, in whole or in part, temporarily or permanently, Plan
transactions dealing with investments, including without limitation, the right
of a Participant to change investment elections or reallocate Account balances
in the event of any conversion, change in recordkeeper, change in investment
funds and/or Plan merger or spinoff.

         (3) In the event of a change in investment funds and/or a Plan
merger or spinoff, the Employee Benefits Committee, in its sole and absolute
discretion, may decide to map investments from a Participant's prior investment
fund elections to the then available investment funds under the Plan. In the
event that investments are mapped in this manner, the Participant shall be
permitted to reallocate funds among the investment funds (in accordance with
Article 8 and any relevant rules and procedures adopted for this purpose) after
the suspension period (if any) is lifted.

         (4) Notwithstanding any provision of the Plan to the contrary, the
investment funds shall be subject to, and governed by, (i) all applicable legal
rules and restrictions, (ii) the rules specified by the investment fund
providers in the fund prospectus(es) or other governing documents thereof and/or
(iii) any rules or procedures adopted by the Employee Benefits Committee
governing the transfers of assets into or out of such funds. Such rules,
procedures and restrictions may limit the ability of a Participant to make
transfers into or out of a particular investment fund and/or may result in
additional transaction fees or other costs relating to such transfers. In
furtherance of, but without limiting the foregoing, the Plan may decline to
implement any investment election or instruction where it deems appropriate."

                  4. Effective as of the close of business on March 31, 2005,
Section 15.4 of the Plan is hereby amended in its entirety to read as follows:

         "Section 15.4. Merger or Consolidation With Another Plan/Transfer
Contributions.

         (a) The Employee Benefits Committee shall have the right to merger or
consolidate all or a portion of the Plan with, or transfer all or part of the
assets or liabilities of the Plan to, any other plan; provided, however that the
terms of such merger, consolidation or transfer are such that each Participant,
distributee, Beneficiary or other person entitled to receive benefits from the
Plan would, if the Plan were to terminate immediately after the merger,
consolidation or transfer, receive a benefit equal to or greater than the
benefit such person would be entitled to receive if the Plan were to terminate
immediately before the merger, consolidation or transfer.

         (b) Amounts transferred to the Plan pursuant to Subsection (1) above
(the "Transfer Contributions") shall be subject to all terms and conditions of
the Plan as in effect from time to time, except to the extent provided on a
Schedule to the Plan which may contain additional terms and conditions governing
the application of the Plan to the Transfer Contributions. The terms of any such
Schedule are hereby incorporated and made part of the Plan and, in the event of
any inconsistency between the terms of the Plan and the terms of the Schedule,
the Schedule shall control with respect to the Transfer Contributions covered by
the Schedule, provided, however, that if such inconsistency

<PAGE>
results from changes made in the provisions of the Plan to comply with
applicable law, then such provisions of the Plan shall control."

         5. Effective as of the close of business on March 31, 2005, the Plan
is hereby amended by adding the following new Schedule A to the end thereof:

                                   "SCHEDULE A
                                   -----------

                   TERMS OF MERGER OF THE ENCODA SYSTEMS, INC.
                PROFIT SHARING PLAN AND TRUST (THE "ENCODA PLAN")

         1.       All capitalized terms used in this Schedule A and not
                  otherwise defined herein shall have the meaning assigned to
                  them by this Plan or the Encoda Plan, as applicable.

         2.       To the extent determined by the Administrative Committee, a
                  separate sub-account will be maintained under Section 8.1 of
                  the Plan for each Participant who had an account balance under
                  the Encoda Plan on March 31, 2005 (the "Effective Date") for
                  the amounts transferred from the Encoda Plan to the Plan (the
                  "Transfer Contributions"). The Transfer Contributions shall
                  further be sub-divided and classified as follows:

                  (a)      Transfer Contributions attributable to pre-tax
                           contributions under the Encoda Plan shall be

                           contributions under the Encoda Plan shall be
                           classified as after-tax contributions under the Plan.

                  (c)      Transfer Contributions attributable to the profit
                           sharing contributions under the Encoda Plan, if any,
                           shall be classified as profit sharing contributions
                           under the Plan.

                  (d)      Transfer Contributions attributable to matching
                           contributions under the Encoda Plan shall be
                           classified as matching contributions under the Plan.

                  (e)      Transfer Contributions attributable to rollover
                           contributions under the Encoda Plan shall be
                           classified as rollover contributions under the Plan.

         3.       Notwithstanding the foregoing, each Participant shall be fully
                  vested in his Transfer Contributions from the Encoda Plan.

         4.       The Transfer Contributions from the Encoda Plan shall be
                  subject to the withdrawal and distribution provisions of the
                  Plan, except as noted below:

                  (a)      Any loan outstanding from the Encoda Plan shall
                           continue in effect until paid off or defaulted under
                           the terms of the loan instruments. All outstanding
                           loans shall be counted towards the maximum number of
                           loans permitted under the Plan.

<PAGE>

                  (b)      A Participant who continues employment after
                           attaining age 70 1/2 will be entitled to elect to
                           commence distribution of his Transfer Contributions
                           Account no later than April 1 of the calendar year
                           following the calendar year in which the Participant
                           attains age 70 1/2 even if such Participant remains
                           employed. Distributions under this paragraph will be
                           made in accordance with Section 9.1(c) (age 59-1/2
                           withdrawals) or Section 9.3(d) (age 70-1/2 minimum
                           distributions), as elected by the Participant."
