prior to the end of such Term.

                  3.       DUTIES

                           4.2      Three (3) salary increases of ten percent
(10%) each, to be made annually during the initial Term of this Agreement,
effective on the first anniversary date of this Agreement.

                  5.       EXPENSES

                           The parties recognize that in the course of
performing his duties hereunder, Employee may incur expenses. Company agrees to
reimburse Employee upon presentation of vouchers for reasonable expenses
incurred by Employee in the performance of his duties hereunder according to the
Company Travel and Expense policy.

                  6.       FRINGE BENEFITS

                           Employee shall be entitled to such fringe benefits
paid for or supplied by Company and shall be further entitled to the following:

                           6.1      Participation in retirement and Employee
benefit plans such as 401(k), tuition reimbursement, health, dental, accident,
disability, life, or other group insurance plans, and other plans as Company
determines from time to time to make available generally to the other executive
employees of Company.

                           6.2      Nothing herein shall be construed to alter,
amend or modify the terms of any stock option plan or policy that may be made
available to Employee by Company. Upon termination of this Agreement for any
reason, any and all such benefits granted under any such plan or policy shall be
governed by the terms and conditions of that plan or policy as it may exist from
time to time.

                  7.       DEATH OR DISABILITY

                           In the event the Employee becomes permanently
disabled so that he is unable to perform his essential employment duties
hereunder, and no requested reasonable accommodation of Employee's disability is
possible, this Agreement shall terminate. Notwithstanding the foregoing, the
compensation then payable by Company to Employee pursuant to Section 4 hereof
shall continue to be paid as if Employee were not disabled in any way, until the
end of the current Term of employment pursuant to Section 2 hereof. For the
purposes of this Agreement, the term "permanent disability" shall mean any
disability lasting ninety (90) calendar days or more.

                           In the event Employee becomes temporarily disabled so
that he is unable to perform his essential employment duties hereunder, and no
requested reasonable accommodation of Employee's disability is possible, then
Company has the right to terminate this Agreement without cause consistent with
the obligations set forth in Section 8.3.1, except as otherwise provided by law.
For the purpose of this Agreement, the term "temporary disability" shall mean
any disability lasting less than ninety (90) calendar days.

                           In the event Employee becomes either permanently or
temporarily disabled, Company shall be entitled to credit against its
obligations under Section 7 of this


                                       2

<PAGE>

Agreement the amount of any and all other disability benefits provided by or
paid for by the Company that inure to Employee's benefit. In the event this
Agreement is terminated pursuant to this Section, should an Employee's
disability cease prior to the expiration of the Term of employment during which
the Agreement was terminated, then Employee remains obligated to return to his
employment duties with the Company for the balance of the then current Term, at
the Company's option.

                           The terms "disability" and "disabled" as used in this
Agreement connote the inability of Employee, for a period of time greater than
seven (7) consecutive business days, to perform his regular employment duties
hereunder as a result of death, mental or physical illness, or injury or
accident.

                  8.       TERMINATION

                           8.1      Notwithstanding  anything herein contained
to the contrary, subject to Section 7 hereof, Company shall have the right to
terminate this Agreement "with cause." A termination "with cause" may occur as
provided by law or as a result of any criminal activity, reckless misconduct,
gross negligence, non-satisfactory performance or abandonment of corporate
responsibility. In the event of a termination by Company with cause, Company
agrees to provide Employee with one (1) day's notice and pay, but will not have
any further obligations under this Agreement, except as provided by law. Company
may elect to waive the one (1) day notice requirement by providing one (1) day's
pay in lieu of notice.

                           8.2      During the Term of this Agreement, Employee
will not have, either directly or indirectly, any more than ten percent (10%)
equity interest in any entity, including any person, partnership, trust or
incorporated or unincorporated association or entity, that is manufacturing,
distributing or marketing products or services directly competitive to those
manufactured, distributed or marketed by Company. It is expressly understood
that such ownership or interest may represent a conflict of interest which may
be grounds for Company to terminate this Agreement with cause.

                           8.3      Notwithstanding anything herein contained
to the contrary, subject to Sections 7 and 8 herein, Company and Employee shall
have the right to terminate the Agreement hereunder without cause.

                           8.3.1    In the event Company terminates the
Agreement without cause, pursuant to Section 8.3 herein, Employee shall receive
the full compensation hereunder for the then remaining Term of this Agreement
pursuant to Section 2. Company reserves the right to exercise its option to pay
the comparable value of any benefit set forth in Section 6, above, to which
employee is entitled, rather than continuing the benefit for the balance of the
Term; EXCEPT THAT, Employee will not have any continuing rights under the 401(k)
plan or other defined benefit plan, except as otherwise provided by law.

                           8.3.2    In the event Employee terminates the
Agreement without cause, Employee must provide Company with at least ninety (90)
days' advance written notice. Upon the expiration of the ninety (90) day notice
period, all obligations by Company to the Employee, except those provided by
law, shall cease. Failure to provide Company with at least ninety (90)


                                       3

<PAGE>

days' advance written notice constitutes grounds for Company to terminate the
Agreement with "cause" as provided in Section 8.1 above, and voids any other
right that Employee may have to compensation, benefits or plans pursuant to
Company programs or policies, except those required to be provided by law.

                           8.4      In the event of a "Change in  Control" of
Company, as defined in Sections 10 and 11 below, the following shall apply:

                           (a)      Upon a Change in Control, if the Term of the
Agreement has less than twelve (12) months remaining, the Term of this Agreement
shall be extended so that a twelve (12) month Term remains from the time of the
Change in Control to the end of the Term. The extended Term of the Agreement
will be on terms identical to those in effect at the time of the Change in
Control. In the event that more than twelve (12) months of the Term exists as of
the time of a Change in Control, there will be no change in the Term.

                           (b)      Employee  commits to continue to perform his
duties under this Agreement for a minimum of twelve (12) months after a Change
in Control. At the end of twelve (12) months after a Change in Control, Employee
has the option to voluntarily terminate this Agreement. In the event Employee
terminates the Agreement pursuant to this Section 8.4, Employee must provide
Company with at least ninety (90) days' advance written notice. Upon expiration
of the ninety (90) day notice period, all obligations by Company to Employee,
except those provided by law, shall cease.

                           (c)      In the event of a Change of Control, all
stock options granted under the Company's 1995 Stock Incentive Plan (the "Plan")
shall immediately become fully vested and exercisable. In addition, in the event
of a Change of Control, the Stock Option Committee shall have the discretion to
accelerate the termination of any stock option granted under the Plan to a date
no earlier than six (6) months following the date of a Change of Control.

                           8.5      With respect to any payments due and owing
as a result of any termination pursuant to this Section 8, Employee may, at
Company's option, receive payment for any such obligations in a one-time lump
sum payment, or, may continue to receive payments in accordance with Company's
usual payroll procedures, as they may exist from time to time.

                  9.       COVENANTS BY EMPLOYEE

                           9.1      Employee hereby acknowledges that Company

(12) months, regardless of the reason for said termination.

                           9.2      The Employee  agrees that he shall not
solicit or attempt to solicit, sell to, lease to or offer to sell to, or offer
to lease to, except on behalf of Company or any Affiliate, any present or future
customer of Company or Affiliate, any goods or services competitive to the goods
and services now or hereafter offered for sale or lease by Company or any
Affiliate for the periods of time set forth in Section 9.1 herein.

                           9.3      The parties hereto recognize that the
covenants of Employee herein contained are unique and that in the event there is
a breach or threatened breach of such covenants, Company shall be entitled, in
addition to any other remedies available to it, to institute and prosecute

performance thereof by Employee, or to enjoin Employee from performing services

controls, is controlled by or is under common control with another person. For

                           9.5      Employee agrees that during the Term hereof
and after the termination of Employee for any reason whatsoever, the Employee
shall not disclose to any person, firm, partnership, company, or other legal

prevent Employee from using any knowledge that he possessed at the time he
commenced his employment with Company or from using any information that is not
confidential.

                           13.5     INDEMNIFICATION

                           (a)      THIRD-PARTY PROCEEDING: Company shall
indemnify Employee, his heirs, or personal representative, made, or threatened
to be made, a party to any threatened, pending, or completed action or
proceeding, whether civil, criminal, administrative, or investigative, by reason
of the fact that he was or is a corporate agent, or serves or served any other
corporation or other enterprise in any capacity at the request of Company, to
the full extent permitted by Florida law, including, without limitation,
indemnification against his expenses and


                                       7

<PAGE>

liabilities in connection with the third-party proceeding if he acted in good
faith and in a manner reasonably believed by him to be in, or not opposed to,
the best interests of Company, and with respect to any criminal third-party
proceeding, had no reasonable cause to believe his conduct was unlawful or in
violation of applicable rules. The termination of any third-party proceeding by
judgment, order, settlement, consent, filing of a criminal complaint or
information, indictment, conviction or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that Employee did not act
in good faith and in a manner which he reasonably believed to be in, or not
opposed to, the best interests of Company or, with respect to any criminal
third-party proceeding, had reasonable cause to believe that his conduct was
unlawful.

                           (b)      SCOPE OF EMPLOYMENT: Pursuant to this

Company.

                           (c)      The term and conditions of this Section 13.5
shall survive the termination of this Agreement and shall apply to any claims
made against Employee, relating to, or arising from Employee's actions pursuant
to this Agreement.
