         WHEREAS, Harris Corporation a Delaware corporation (the "Corporation"),

         WHEREAS, pursuant to Section 13.3 of the Plan, the Compensation

         NOW, THEREFORE, BE IT RESOLVED, that pursuant to the power of amendment
in Section 17.1 of the Plan and the delegation of such power pursuant to Section
13.3 of the Plan, effective September 1, 2005, Section 8.2(c)(1) of the Plan is
hereby amended in its entirety to read as follows:

                  "(1) Availability. Only pre-tax contributions, after-tax
         contributions and matching contributions may be invested in the Harris
         Stock Fund. If the aggregate of a Participant's pre-tax contribution
         and after-tax contribution for any payroll period is equal to or
         greater than 5% of the Participant's Compensation for such payroll
         period, the aggregate of the pre-tax contribution and after-tax
         contribution invested in the Harris Stock Fund for any payroll period
         shall not exceed 1% (or such larger percentage established by an
         appropriate committee of the Board from time to time) of the
         Participant's Compensation for the payroll period. If the aggregate of
         a Participant's pre-tax contribution and after-tax contribution for any
         payroll period is less than 5% of the Participant's Compensation in any
         payroll period, the aggregate of his or her pre-tax contributions and
         after-tax contributions invested in the Harris Stock Fund for the
         payroll period shall not exceed 20% of the Participant's aggregate
         pre-tax contribution and after-tax contribution for the payroll period.
         The portion of any pre-tax contribution or after-tax contribution that
         is attributable to a discount from fair market value on shares of
         Harris Stock shall be disregarded for purposes of the two foregoing
         sentences. To the extent that pre-tax contributions or after-tax
         contributions are invested in the Harris Stock Fund, the matching
         contributions attributable thereto also shall be invested in the Harris
         Stock Fund."

         APPROVED by the HARRIS CORPORATION EMPLOYEE BENEFITS COMMITTEE on this
19th day of August, 2005.
