Pre-Tax Contributions, Matching Pre-Tax Contributions or Profit Sharing
Contributions that are not credited to the Participant's Retirement Plan account
because of a limitation imposed under section 401(a)(17),

<PAGE>

401(k)(3), 401(m)(2)(A), 402(g) or 415 of the Code shall be credited to the
Participant's Account at the time or times any such amount would have been
credited to the Participant's Retirement Plan account but for such a limitation.

         (b)      Time of Elections. The Committee shall determine the period of
time in the beginning of each Plan Year during which eligible employees may
elect to participate in the SERP pursuant to Section 4.1(a) or (c) with respect
to Compensation not yet earned. Any eligible employee who is hired by the
Corporation or any of its affiliates after the end of such period may elect to
participate in the SERP for such Plan Year within the first 30 days of his or
her employment. Elections to participate in the SERP must be made in the manner
prescribed by the Committee.

         (c)      Permitted Salary Deferral Elections. In addition to the
Compensation under Section 4.1 that a Participant may elect to defer, the
Committee, in its sole discretion, may permit a Participant to elect to defer
the receipt of any portion of his or her Compensation by completing an election
form at the time and in the manner prescribed by the Committee. An amount equal
to such portion of the Participant's Compensation shall be credited to his or
her Account.

4.2. Special Award Amounts. The Compensation Committee, in its sole discretion,
may grant a special award to any Participant, and an amount equal to the award
shall be credited to such Participant's Account.

his or her Account attributable to such amount

                      ARTICLE V - ACCOUNTS AND INVESTMENTS

5.1. Establishment of Accounts. An Account shall be established on the books of

Committee, except that 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 even if such fund is otherwise available under the
SERP.

         (b)      Investment Elections to Remain in Effect. A Participant's
investment election shall remain in effect until the Participant changes it. If
an investment fund selected by a Participant is no longer offered under the SERP
and the Participant does not file a new investment election with the Committee,
then the portion of the Participant's Account previously deemed invested in such
investment fund shall be invested in the Balanced Fund.

         (c)      Timing. A Participant's Account shall be credited periodically
with amounts equal to the gains and losses that would have been realized by the
Corporation if the Account had been invested as it is deemed to be invested.

                     ARTICLE VI - VESTING AND DISTRIBUTIONS

6.1. Vesting. Amounts credited to a Participant's Account pursuant to Section
4.1 (as adjusted for deemed gains and losses pursuant to Section 5.2) shall
become vested at the same time and to the same extent as their corresponding
contributions to the Retirement Plan become vested. Amounts credited to a
Participant's Account pursuant to Sections 4.2 and 4.3 shall become vested as
determined by the Committee.

6.2. Time of Payment. A Participant shall commence receiving distributions from
his or her Account in January of the calendar year following the later of (i)
the calendar year in which such Participant attains age 55 and (ii) the calendar
year in which the Participant terminates employment with the Corporation and its
affiliates, provided that a Participant who terminates employment before
attaining age 55 and whose vested interest in his or her Account at the time of
such termination is less than $25,000 (or such other amount as may be designated
by the Committee) shall receive a single sum distribution of such vested
interest as soon as practicable following his or her termination of employment.

6.3. Form of Distribution.

         (a)      Elections. A Participant may elect the form of distribution of
his or her vested Account balance by filing an election form with the Committee
before October 1st of the calendar year in which such Participant terminates
employment with the Corporation and its affiliates, except that if a Participant
terminates employment with the Corporation and its affiliates on or after
October 1st of a calendar year in connection with a Reduction in Force, then the
Participant must elect the form of distribution before the end of such calendar
year. A Participant may change a prior election regarding the form of
distribution by filing a new election form with the Committee at the time and in
the manner permitted by the Committee, provided that such form is received by
the Committee no later than a date determined by the Committee within the
calendar year prior to the year in which such distribution was to be paid or
commence pursuant to the Participant's prior election.

         (b)      Available Forms of Distribution. A Participant may elect to
receive payment of his or her vested Account balance in any one of the following
forms:

                  (1)      a single sum;

                  (2)      installments over a five-year period;

                                        4

<PAGE>

                  (3)      installments over a seven-year period;

                  (4)      installments over a ten-year period; or

                  (5)      installments over a fifteen-year period.

Installment payments shall be made annually, unless the annual installment
amount would be greater than the threshold amount established by the Committee
in its sole discretion from time to time ($250,000 for 2003).

         (c)      Default Form of Distribution. A Participant who has not filed
an election under Section 6.3(a) shall receive the distribution of his or her
vested Account balance in installments over ten years.

         (d)      De Minimus Amounts. Notwithstanding Section 6.3(b), if a
Participant's vested interest in his or her Account is less than an amount
determined by the Committee, in its sole discretion, from time to time ($25,000
for 2003) that is applied uniformly to all Participants who become entitled to a
distribution after the Committee makes such a determination, then the
Participant's vested interest in his or her Account shall be paid in a single
sum as soon as reasonably practicable after the Participant becomes entitled to
a distribution.

6.4. Reemployment. Installment payments to a Participant shall cease upon such
Participant's reemployment by the Corporation or one of its affiliates. The
Participant's remaining vested interest in his or her Account shall be
distributed to the Participant upon his or her subsequent termination of
employment with the Corporation and its affiliates according to the
Participant's most recent election made pursuant to Section 6.3.

6.5. Death. If a Participant shall die before the entire vested interest of his
or her Account is distributed, then the remaining vested interest shall be paid,
in the manner such vested interest would have been paid to the Participant, to
the beneficiary or the beneficiaries designated by the Participant on the form
and in the manner prescribed by the Committee. A Participant may revoke or
change his or her beneficiary designation at any time by filing a new
beneficiary designation form with the Committee. If a Participant does not
designate a beneficiary under the SERP or if no designated beneficiary survives
the Participant, then the vested interest of his or her Account shall be
distributed to the Beneficiary or Beneficiaries entitled to his or her accounts
under the Retirement Plan (or who would be so entitled if the Participant had
Retirement Plan accounts).

6.6. Financial Hardship. A Participant may request a payment of all or a portion
of his or her vested Account interest on account of a Financial Hardship by
submitting a written request to the Committee accompanied by documentation
evidencing the Financial Hardship. The Committee shall review the request and
shall determine, in its sole discretion, whether a Financial Hardship exists.
Any payment on account of the Participant's Financial Hardship shall be limited
to an amount that the Committee, in its sole discretion, determines is
reasonably necessary to satisfy the Participant's Financial Hardship needs.

6.7. Change in Control. Notwithstanding anything herein to the contrary, in the
event of a Change in Control, each Participant's vested interest in his or her
Account shall be either

                                        5

<PAGE>

distributed to such Participant in a single sum as soon as practicable or
transferred (or retained) in a grantor trust established by the Corporation and
distributed in accordance with the Change in Control election on file with the
Committee. A Participant may change his or her election under this Section 6.7
by filing a new election form with the Committee at the time and in the manner
permitted by the Committee, provided that such election form is received by the
Committee by the earlier of (i) October 1st of the calendar year before the year
in which such Change in Control occurs and (ii) the last date the Committee, in
its sole discretion, determines that the Participant was not likely to be aware
that a Change in Control was pending. The provisions of this Section 6.7 may not
be amended after the date of a Change in Control without the written consent of
a majority of those individuals with an Account balance under the SERP on the
date of such Change in Control.

6.8. Overpayments of Installments. In the event that a payment is made with
respect to a Participant's Account which exceeds the amount to which the
Participant is entitled, future installment payments shall be reduced in any
manner which the Committee, in its sole discretion, deems equitable.

6.9. Withholding for Taxes. For each calendar year in which a Participant's
Compensation is reduced pursuant to the Participant's election under the SERP,
the Corporation shall withhold from the Participant's payments of compensation
for such year any taxes imposed upon the Participant pursuant to section 3121(v)
of the Code in respect to the amount by which the Participant's Compensation is
reduced. The Corporation shall have the right to deduct any federal, state or
local income, employment or other taxes required by law to be withheld with
respect to any payments to be made under the SERP, and to withhold such amounts
from any payment otherwise due the Participant (or his or her beneficiary).

                          ARTICLE VII - ADMINISTRATION

7.1. Authority of Committee. The SERP shall be administered by the Committee.
The Committee shall, in its sole and absolute discretion, have the complete
authority to interpret the SERP, to adopt rules for carrying out the purposes of
the SERP and to make all other determinations necessary or advisable for the
administration of the SERP. To the extent practicable, the SERP shall be
administered in a manner consistent with the administration of the Retirement
Plan. Nevertheless, any decision or interpretation of any provision of the SERP
made by the Committee shall be final and conclusive, and shall be binding on all
Participants (and their beneficiaries). A Participant who has any authority to
make any SERP administrative decisions may not participate in any such decision
that may affect his or her rights or obligations under the SERP, unless the
decision affects all Participants.

7.2. Delegation of Authority. The Committee may delegate any of its
responsibilities, powers or duties under the SERP to any person or committee.
The Committee or its delegate may employ such attorneys, agents and advisors as
the Committee or such delegate may deem necessary or advisable to assist it in
carrying out its duties hereunder.

7.3. Liability. No member of the Committee and no person to whom the Committee
has delegated any responsibility, power or duty under the SERP shall be liable
for any action or

                                        6

<PAGE>

failure to act under this SERP, except where such action or failure to act was
due to gross negligence or fraud.

                        ARTICLE VIII - GENERAL PROVISIONS

8.1. Amendment and Termination. Subject to Section 6.7, the committee of the
Board of Directors of the Corporation that has the power to amend or terminate
the SERP may do so at any time, provided that no amendment or termination of the
SERP shall reduce or cancel the amount credited to any Participant's Account.

8.2. Anti-Alienation. A Participant's rights and interest under the SERP may not
be assigned or transferred except by will or the laws of descent or
distribution, or as may be required under ERISA pursuant to a qualified domestic
relations order. Any other purported transfer, assignment, pledge or other
encumbrance or attachment of any payments or benefits under the SERP shall not
be permitted or recognized and shall be void.

8.3. Funding. The Corporation may, but is not required to, establish a trust to
fund the amounts credited to Accounts under this SERP, provided that the assets
in such trust shall be subject to the claims of the Corporation's general
creditors in the event of insolvency. Any payments pursuant to the SERP shall be
made out of the general assets of the Corporation, and Participants (and
beneficiaries) shall have no interest in any fund or specific asset of the
Corporation. The rights of each Participant (and beneficiary) to any payments
under the SERP shall be solely those of any unsecured creditor of the
Corporation.

8.4. Severability. If any provision of the SERP is found illegal or invalid by
any court having proper jurisdiction, then such provision shall be construed by
such court to reflect most nearly the Corporation's original intent in adopting
the SERP, consistent with applicable law, and the illegality or invalidity shall
not affect the remaining provisions of the Plan.

8.5. Not a Contract of Employment. The SERP shall not constitute a contract of
employment or in any manner obligate the Corporation to continue the employment
of any employee.

8.6. Successors and Assigns. The provisions of the SERP shall bind and inure the
Corporation and its successors and assigns, as well as each Participant and
beneficiary.

8.7. Construction. The SERP shall be construed in accordance with the laws of
the State of Florida.
