            WHEREAS, the Company desires to continue to employ the Executive as

            NOW, THEREFORE, in consideration of the mutual covenants herein
contained, the parties hereto agree as follows:

            1. Term. The Company hereby offers to continue to employ the
Executive as President, Swisher International, Inc., and the Executive hereby
accepts such employment. This Agreement shall be effective as of the date hereof
and shall continue to be effective for the period ending on the "Expiration
Date" (such period being hereinafter referred to as the "Term"). The "Expiration
Date" shall initially be December 31, 1997, but effective as of December 31,
1995 and as of each December 31 thereafter, the Term shall automatically be
extended one additional year and the Expiration Date will be adjusted
accordingly, unless, not later than the preceding July 1 of such year, the Chief
Executive Officer on behalf of the Company or the Executive shall have given
notice to the other that the Term shall not be so extended. The period measured
from the date hereof through the Expiration Date (as applicable from time to
time), determined without regard to termination of the Executive's employment
hereunder on any earlier date, is hereinafter referred to as the "Period of
Service."

            2. Services and Duties. While he is employed during the Term, the
Executive agrees to serve the Company as President, Swisher International, Inc.
In such capacity, Executive shall perform all reasonable acts customarily
associated with such position.

            3. Compensation and Benefits. While employed by the Company, during
the Term, the Executive shall receive the following compensation and benefits:


                                       1
   2
 
            (a) Base salary in the amount of Two Hundred Twenty-Eight Thousand
       Dollars ($228,000) per annum, payable in semi-monthly installments and
       subject to such deductions as required by law, due in respect of the
       various employee benefit plans in which the Executive participates or as
       otherwise agreed by the Executive. Executive's base salary will be
       reviewed annually by the Compensation Committee of the Board of Directors
       for possible increases based upon Executive's performance.

            (b) Annual incentive compensation based on individual and company
       performance targets to be mutually agreed upon each year by the parties.
       The amount of the annual incentive compensation payable will be
       determined under the Company's management incentive plan (or any
       successor plan) in effect from time to time, it being understood that the
       annual incentive compensation "target" rate under the current plan shall
       be forty percent (40%) of Executive's annual base salary.

            (c) Benefit programs made available from time to time by the Company
       to executives and/or other salaried employees, including but not limited
       to the Company's retirement plans; 401(k) plan; executive life insurance
       program; medical and dental plan; short-term and long-term disability
       coverage; vacation and holidays.

            (d) Stock options, restricted stock awards and/or stock appreciation
       rights or any similar equity incentive rights as determined by the
       Compensation Committee of the Board of Directors of the Company.

            4. Business Expense Reimbursement. While employed by the Company,
during the Term, Executive shall be entitled to reimbursement for all reasonable
and necessary out-of-pocket expenses incurred by him in performing services
hereunder, subject to appropriate documentation.

            5. Termination of Employment.

            (a) Death or Disability. Executive's employment shall terminate upon
his death or "disability," as hereinafter defined. For purposes of this
Agreement, the Executive shall be deemed to have terminated employment as a
result of a "disability" if (1) for medical reasons he is unable to perform his
material duties to the Company for a total of six (6) months, whether or not
consecutive, in any twelve (12) month period and (2) subject to applicable law,
the Company terminates the Executive's employment as a result of such
"disability" by written notice. The initial determination of the "medical
reasons" shall be made by a physician chosen by the Company whereby the
Executive shall submit to a reasonable medical examination. If the Executive
shall dispute such initial determination, the Executive shall submit to a
reasonable medical examination by a physician chosen by the Executive. If the
Executive shall continue to dispute the initial determination, the final
determination shall be made by majority vote of three physicians, one the
Executive's chosen physician, one the Company's chosen physician, and one 

                                       2

   3

chosen by such two physicians. Such final determination will be final and
binding for all purposes hereunder.

            (b) Termination for "Cause". The Company may terminate the
Executive's employment for "cause." For purposes of this Agreement, the
Executive's employment shall be considered to have been terminated for "cause"
if such termination occurs on account of:

            (i) the Executive's conviction by a court of competent jurisdiction
       of any crime constituting a felony under the laws of the United States or
       one of its political subdivisions (or the Executive's plea of guilty or
       no lo contendere to a charge of any such crime); and

            (ii) the Executive engaging in willful misconduct in the performance
       of his material duties to the Company resulting in demonstrable economic
       harm to the Company.

            (c) Termination for "Good Reason". The Executive may terminate his
employment for "good reason." For purposes of this Agreement, "good reason"
means the occurrence of one of the following:

            (i) the Executive suffers any diminution in his position, title,
       reporting relationship, responsibilities or authority; or

            (ii) the Executive is assigned additional responsibilities without
       appropriate remuneration or that unreasonably increase his work load; or

            (iii) the adverse and substantial alteration of the nature and
       quality of the secretarial and administrative support provided to the
       Executive; or

            (iv) the Executive suffers a decrease in his level of compensation
       because of one or more of the following:

                     (A) the Executive's then-current level of base salary as
            described in Section 3(a) is reduced; or

                     (B) with respect to any fiscal year of the Company, the
            Company fails to provide the Executive with annual incentive
            compensation which is based on terms and conditions (including, but
            not limited to, the targeted percentage of annual base salary
            payable) comparable to those described in Section 3(b); or

                     (C) the Executive suffers a significant reduction in
            employee benefit coverages (including but not limited to those
            programs and arrangements described in Section 3(c)) that are
            provided to the Executive; or

                                       3
   4

            (v) without the Executive's prior written consent, the Executive's
       office location is relocated by more than twenty-five (25) miles from the
       existing location; provided, that, such relocation increases the distance
       from the Executive's principal residence to such office.

            6. Consequences of Termination of Employment.

            (a) Without "Cause" or for "Good Reason". In the event that the
Company terminates the Executive's employment without "cause" or the Executive
terminates his employment for "good reason" and subject to the conditions set
forth below, the Company shall provide the following payments and benefits (each
of which shall be calculated without regard to any reduction or change that
constitutes "good reason") to the Executive for the Period of Service:

            (i) The Company shall continue to pay to Executive the semi-monthly
       base salary amounts under Section 3(a).

            (ii) The Company shall continue to make incentive compensation
       payments to the Executive under Section 3(b) in the amounts equivalent to
       his "targeted" incentive compensation under the management incentive plan
       in effect at the time of his termination.

            (iii) To the extent provided below in Sections A, B and C, the
       Executive shall continue to participate in the Company benefit programs
       (including without limitation the Company's retirement plans; 401(k)
       plan; executive life insurance program; medical and dental plan;
       short-term and long-term disability coverage; accident insurance
       coverage; Section 125 cafeteria plan) under Section 3(c) as described
       herein.

                   A. Welfare Benefits. All employee welfare benefit coverage 
       shall apply to the Executive and any of his dependents who would have 
       been eligible for coverage if the Executive had continued to be 
       employed by the Company for the remaining Period of Service. The 
       Executive shall be required to make all employee contributions due in 
       respect of the benefit coverage on the same basis as active employees of
       the Company. At the expiration of the Period of Service, the Executive
       shall be treated as a then terminating employee of the Company with
       respect to the right to elect continued medical and dental coverages in
       accordance with Section 4980B of the Internal Revenue Code of 1986, as
       amended (the "Code"), or any successor provision thereto and with
       respect to any similar welfare benefit continuation rights. The
       Executive shall receive age and service credit during the Period of
       Service for purposes of retiree medical coverage.
        
                   B. Retirement Plan Benefits. The Executive shall continue 
       active participation under the Company's tax-qualified and supplemental 
       defined
 
                                       4
   5

       benefit plans or any other tax qualified or supplemental defined benefit
       plan of the Company or an affiliate in which the Executive actively
       participates at the time of his termination of employment ("Retirement
       Plans"), until the expiration of the Period of Service. The calculation
       of Employee's pension benefit under the Retirement Plans shall include
       credit for the amounts paid under Sections 6(a)(i) and 6(a)(ii) and the
       duration of such payments for purpose of determining length of service
       and age, and amounts equivalent to the resulting benefit shall be paid
       out of a non-qualified plan to the extent necessary to preserve the
       tax-qualified status of any defined benefit plans intending to be tax
       qualified. The Company shall take all necessary action to effectuate the
       foregoing including amending the supplemental plan.

                   C. 401(k) Plan Benefits. The Executive shall continue active
       participation under the Company's 401(k) Plan, or any other tax qualified
       (or supplemental, if applicable) defined contribution plan of the Company
       or an affiliate in which the Executive actively participates at the time
       of his termination of employment ("401(k) Plans") until the expiration of
       the Period of Service. To the extent necessary to preserve tax-qualified
       status of any defined contribution plan intended to be qualified, the
       Executive may instead receive a lump-sum cash payment promptly following
       his termination of employment equal to the aggregate employer
       contributions that would have been made on behalf of the Executive under
       the 401(k) Plans until the expiration of the Period of Service, assuming
       he had elected to make the maximum contributions under the 401(k) Plan
       that is subject to employer contributions.

            (iv) Stock options which have been awarded to Executive prior to his
       termination shall become immediately fully vested and exercisable and
       shall remain exercisable until the earlier of their expiration date or
       the third anniversary of termination of his employment and the Company
       hereby agrees that all actions and consents that are required to be taken
       or obtained in order to effectuate the foregoing shall be so taken or
       obtained.

            In addition, the Company shall pay to the Executive any portion of
accrued but unpaid base salary, incentive compensation payments, stock option
and equity incentive rights and employee benefits to which the Executive is
entitled up until the date of the Executive's termination of employment.

            (b) Any Other Termination of Employment. In the event of termination
by the Company of the Executive's employment for "cause" under Section 5(b),
termination of employment by the Executive other than for "good reason,"
termination of the Executive's employment due to death or disability or any
other termination of the Executive's employment other than as described in
Section 6(a), the Executive shall be entitled to his (i) accrued base salary
through the date of termination, (ii) incentive compensation bonus which has
been accrued but not yet paid, for any completed fiscal year of the Company
ending prior to termination of employment, and (iii) employee 

                                       5
   6

benefits (in accordance with the terms of the applicable payroll practices and
benefit programs).

            7. Excise Tax Gross-Up Payment. Notwithstanding anything in this
Agreement to the contrary, in the event it shall be determined that any payment
or distribution by the Company or any other person or entity to or for the
benefit of the Executive is a "parachute payment" (within the meaning of Section
280G(b) (2) of the Code), whether paid or payable or distributed or
distributable pursuant to the terms of this Agreement or otherwise in connection
with, or arising out of, his employment with the Company or a change in
ownership or effective control of the Company or a substantial portion of its
assets (a "Payment"), and would be subject to the excise tax imposed by Section
4999 of the Code (the "Excise Tax"), concurrent with the making of such Payment,
the Company shall pay to the Executive an additional payment (the "Gross-Up
Payment") in an amount such that the net amount retained by the Executive, after
deduction of any Excise Tax on such Payment and any federal, state or local
income tax and Excise Tax on the Gross-Up Payment shall equal the amount of such
Payment.

            8. No Obligation to Mitigate. It is further agreed that the
Executive shall be under no obligation to minimize or mitigate damages by
seeking other employment, and the obtaining of any such other employment shall
in no event effect any reduction of the Company's obligation to make the
payments and provide the benefit coverages required under this Agreement. In
addition, the Company's obligation to make the payments and provide the benefits
required under this Agreement shall not be affected by any circumstances,
including, without limitation, any set-off, counterclaim, recoupment, defense or
other rights which the Company may have against the Executive.

            9. Confidential Information. The Executive shall not during the
period of his employment or at any time thereafter disclose or communicate to
any unauthorized person, firm or corporation, or use for his own purposes, trade
secrets, confidential commercial information, or any other information,
knowledge or data of the Company or any of its affiliates which is not generally
known to the public and shall use his best efforts to prevent the publication or
disclosure by any person of any such secret, information, knowledge or data. All
documents and objects made, compiled, received, held or used by the Executive
while employed by the Company in connection with the business of the Company
shall be and remain the Company's property and shall be delivered by the
Executive to the Company upon the termination of the Executive's employment or
at any earlier time requested by the Company.

            10. Non-Assignment; Successors. This Agreement and all rights
hereunder are personal to the Executive and shall not be assignable; provided,
however, all of the Executive's rights to compensation following his death shall
inure to the benefit of his heirs, estate, personal representatives or designees
or other legal representatives as the case may be. Any person, firm or
corporation (including, if applicable, any ultimate parent entity thereof)
succeeding to the business of the Company by merger, purchase, consolidation or
otherwise shall assume by contract or operation of law all obligations of the
Company hereunder.
