    (b) LONG TERM DEFERRED INCENTIVE PLAN.
        ----------------------------------

    (i) As used in this Section 4(b), the following terms have the following
meanings:

            "Cost Basis" means, with respect to an Equity Interest in a
         Subsidiary, the sum of (A) the aggregate amount paid by the Company or
         any other Subsidiary to purchase such Equity Interest on or prior to
         the Determination Date plus (B) the amount of all contributions to the
         capital of such Subsidiary made by the Company and/or any other
         Subsidiary on or prior to the Determination Date.

            "Determination Date" means the earlier to occur of (A) June 30, 2001
         or (B) the end of the calender month next preceding the calender month
         in which the Employee's employment with the Company terminates.

            "Economic Incentive Value" means, with respect to an Equity
         Interest, the amount obtained by subtracting (A) the Cost Basis of such
         Equity Interest from (B) the fair market value of such Equity Interest
         as of the Determination Date determined in accordance with Section
         4(b)(ii). Economic Incentive Value maybe a negative number.

            "Equity Interest" means, with respect to any Subsidiary, all of the
         shares of the capital stock of such Subsidiary which are owned by the
         Company or any other Subsidiary on the Determination Date.

            "LTDIP Amount" means an amount equal to five percent (5%) of the sum
         of the Economic Incentive Values of all Equity Interests.

            "Payment Dates" means June 30, 2002; June 30, 2003; and June 30,
         2004.

            "Subsidiary" means a corporation a majority of whose voting stock is
         owned by the Company directly or indirectly on the Determination Date.

    (ii)  If the Company is obligated to pay the LTDIP Amount to the Employee
pursuant to Section 4(b)(iii), the fair market value of each Equity Interest
shall be determined in good faith by the Company's Board of Directors and
provided to the Employee in writing (the "DETERMINATION NOTICE") within 9O days
after the Determination Date. The Determination Notice shall also set forth the
LTDIP Amount as determined by the Board of Directors and the calculation
thereof. If the Employee objects to the fair market value of any Equity Interest
proposed in the Determination Notice (each item so objected to being herein
referred to as "Disputed Value Amount"), he shall give notice thereof in writing
(the "OBJECTION NOTICE") to the Company within 30 days after the Determination
Notice is given. The Objection Notice shall identify each Disputed Value Amount,
set forth the Employee's basis

                                       4
<PAGE>

for objecting thereto, state the amount proposed by the Employee for such fair
market value and his calculations thereof. If the Employee fails to give an
Objection Notice within such 30-day period, the Board's determination as set
forth in the Determination Notice shall be deemed to be accepted and agreed to
by the Employee in its entirety, and it shall be binding on the parties. If the
Employee gives an Objection Notice, and if the parties are unable to reach
agreement on all Disputed Value Amounts within 30 days thereafter, then, in such
case, the fair market value of each Equity Interest which then remains in
dispute shall be determined in writing (the "VALUATION REPORT") by a nationally
recognized investment firm (the "VALUATION FIRM") which is engaged in the
valuation of businesses and their securities. The Valuation Firm shall be
selected by the Company's Board of Directors. If the Valuation Firm determines
that the fair market value of any Equity Interest which is in dispute is greater
than the fair market value thereof specified in the Determination Notice, then,
in such case, the Company shall pay the fees and costs of such determination by
the Valuation Firm. If the Valuation Firm determines that the fair market value
of an Equity Interest which then remains in dispute is equal to or less than the
fair market value thereof specified in the Determination Notice, the Employee
shall be obligated to reimburse the Company on demand for the entire amount of
the fees and costs of such determination by the Valuation Firm. The Company
shall be entitled, but not obligated, to collect any such reimbursement
obligation of the Employee by offset against the Company's payment obligations
under Section 4(b) (iii) in the order of their maturity. The determination of
the fair market value of any Equity Interest set forth in the Valuation Report
shall be conclusive and binding on the parties. The Company shall provide the
Employee with a copy of the Valuation Report promptly upon its receipt thereof.

    (iii) On each of the Payment Dates, the Company shall pay to the Employee an
amount equal to one-third of the LTDIP Amount; provided, however, that the
                                               --------- -------
Company shall not be obligated to pay, and the Employee shall not be entitled to
receive payment of, any LTDIP Amount if prior to June 30, 2001 his employment
with the Company is terminated for "cause" (as defined in Section 6(b)) or by
his resignation.

dependents on the date of death) for the period required by applicable law
(provided, however, that if the Company terminates such health insurance
 --------  -------
coverage, if any, for its employees or their dependents generally, the Company
may discontinue such coverage for such dependents on the date of such general

such termination occurs, pay to the Employee that portion of the Bonus, if any,
for such fiscal year which is determined by multiplying the full amount of such
bonus (calculated as if the Employee were an employee hereunder for the entire

dependents on the date of such general termination), (ii) continue to pay to the
Employee the salary provided for in Section 3(a) for a period ending on the

anniversary of the date of termination and (iii) within 9O days after the end of
the fiscal year in which such termination occurs, pay to the Employee that
portion of the Bonus, if any, for such fiscal year which is determined by
multiplying the full amount of the Bonus (calculated as if the Employee were an
employee hereunder for the entire fiscal year) by a fraction the denominator of
which is 365 and the numerator is which is the number of days in the period from
the beginning of such fiscal year to the date of termination. The Company's
obligation to make salary continuation payments under this Section 6(f) shall be
reduced dollar-for-dollar by any benefits which the Employee receives under any
policy of disability insurance for which the Company has paid the premiums
(directly or indirectly).

    (g) Notwithstanding any of the foregoing provisions of this Section 6
requiring that the Company provide health insurance coverage to the Employee
and/or his dependents after the date of termination of employment, the Company

of salary continuation for services rendered by him as an employee, consultant
or otherwise to any person, corporation or other entity.

SECTION 7.  LEASING ARRANGEMENT.
-------------------------------

    (a)   As of the date hereof, the Employee is an employee of Staff Leasing,
Inc. ("SLI") and is providing the services described in Section 1 to the Company
(on a full-time basis) pursuant to a lease agreement between SLI and the Company
(the "Lease Agreement"). The Employee receives his compensation and benefits
directly from SLI. He receives no compensation or benefits directly from the
Company. In effect, the Company is leasing the Employee's services from SLI and
is making lease payments to SLI for the same.

    The Company entered into the Lease Agreement upon the recommendation and at
the request of the Employee. The terms of the Lease Agreement were negotiated by
the Employee. The salary, benefits and other compensation provided by SLI to the
Employee are comparable to the salary, benefits and other compensation provided
for in Section 3, and it is the intention of the parties that such comparability
shall continue for so long as the Lease Agreement is in effect.

    (b)  For so long as the Lease Agreement is in effect, the Company shall have
no obligation to pay any salary, benefits or other compensation directly to the
Employee pursuant to Section 3 (and shall have no payroll related obligations in
respect thereof), and the Employee shall look solely to SLI for the payment or
provision thereof. The Company's only obligation in respect thereof shall be to
make the lease payments to SLI under the Lease Agreement in amounts sufficient
to support the contemplated salary, benefits and other compensation to be paid
or provided to the Employee. Further, the Company shall have no liability or
obligation to the Employee in the event that it is determined at any time that
the salary or benefits paid or provided to the Employee are less than, or less
favorable to the Employee, than those contemplated by Section 3, it being
understood and agreed that the Employee has negotiated the terms of the Lease
Agreement and the terms of his compensation from SLI. The Employee shall be
responsible for ensuring that the terms of the leasing arrangement with SLI
provide him with salary benefits and other compensation comparable to those
provided for in Section 3.

    (c)   The Company shall have the right at any time to terminate the Lease
Agreement and thereafter to (i) employ the Employee directly in accordance with
the terms of this Agreement (other than the terms of this Section 8) or
(ii) employ the Employee indirectly through another leasing company provided
that the salary, benefits and other compensation provided by such other leasing
company are at all times comparable to those provided for in Section 3.
