"Agreement") provides for the allocation, settlement, and financial statement
presentation of federal income taxes in the consolidated federal income tax
return of SWISHER INTERNATIONAL GROUP INC. (the "Sub") and its subsidiaries (the

COMPANY (the "Parent").

                              W I T N E S S E T H :

                  WHEREAS, the parties hereto are members of an affiliated group
(the "Group") as defined in Section 1504(a) of the Internal Revenue code of
1986, as amended (the "Code").

                  WHEREAS, the Parent has agreed to ensure that the Group has
properly elected to file consolidated federal income tax returns using the
methods prescribed in Treasury Regulations Section 1.1502-33(d)(3) and Treasury
Regulations Section 1.1552-1(a)(2) for purposes of determining the earnings and
profits of each member of the Group and of the
Group;

                  WHEREAS, the Parent and the members of the Group agree that as
a condition precedent to filing a consolidated tax return it is necessary to
properly provide in this Agreement methods for (1) allocating consolidated
federal income tax liability for federal

income tax purposes among members of the Group, (2) reimbursing Parent for
payment or assumption of such tax liability on behalf of members of the Group
and (3) having those members of the Group that benefit from the losses or
credits of other members compensate such other members for use of the benefits;
and

                  WHEREAS, while the Parent and members of the Group currently
file a consolidated tax return, both parties acknowledge that the Parent has the
right to deconsolidate SubGroup, in which event, Parent would no longer be
obligated to the IRS for federal taxes which relate to SubGroup;

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

                                    ARTICLE 1

                  1.1      Preparation

                  The parent shall prepare and file a consolidated federal
income tax return including SubGroup until notice of revocation is given by
Parent to SubGroup.

                  1.2      Payment of Tax

                  The Parent shall act as sole agent for SubGroup and all other
members of the Group for payment of any tax liability as may be shown on a
consolidated federal income tax return of the Group and for all other purposes
as required by Treasury Regulations Section 1.1502-77(a).

                  1.3      Intercompany Payments

                  The Parent and SubGroup shall accrue responsibilities for
payment and make payments to each other in such amounts, at such time and in
such manner as provided in


                                       -2-

<PAGE>



Article 2 of this Agreement. The obligations created as a result of this
Agreement between the Parent and SubGroup shall be treated as if between an
unrelated party, on an arms-length basis.

                  1.4      Consideration

                  In consideration for Parent and other members of the
consolidated group remaining liable for the tax liability of SubGroup, SubGroup
hereby agrees to the terms and conditions contained in this Agreement, including
the obligation to reimburse Parent for payment or assumption of any SubGroup tax
liability.

                                    ARTICLE 2

                  2.1       Determination of SubGroup's Taxable Income Lost and
                            Taxable Gains

                  (a) SubGroup shall collectively (i.e., disregarding payments
and transactions between SubGroup members) determine its taxable income or loss
on a separate return basis for each income year calculated pursuant to Treasury
Regulations Section 1.1502-12 ("Separate Taxable Income or Tax Loss").

                  (b) In addition to determining its Separate Taxable Income or
Tax Loss for each taxable year, SubGroup shall collectively determine its
taxable capital gains and its taxable gains subject to Section 1231 of the Code
with respect to each transaction giving rise to such taxable gain ("Separate
Taxable Gains"). Such determination shall be made as soon as is administratively
feasible after each event which gave rise to each such Separate Taxable Gain.

                  2.2      Determination of Tax Liability by SubGroup

                  (a) To the extent that SubGroup collectively has Separate
Taxable Income or Separate Taxable Gains during any income year, SubGroup shall
be liable for the payment to Parent of an amount equal to SubGroup's "Separate
Tax Liability."

                  (b) For all purposes of this Agreement, SubGroup's "Separate
Tax Liability" shall be equal to the sum of (i) the federal tax liability which
SubGroup would have incurred with respect to this Separate Taxable Income if
SubGroup had filed its own separate consolidated federal tax return and (ii) the
federal tax liability which SubGroup would have incurred with respect to its
Separate Taxable Gains if SubGroup had filed its own separate consolidated
federal tax return.

                  (c) To the extent that SubGroup had Separate Taxable Income in
any year and is eligible to carry forward a net operating loss of SubGroup from
a prior income year to the current income year, the Separate Taxable Income of
SubGroup shall be reduced by such net operating loss.

                  (d) To the extent that SubGroup has Separate Taxable Gains in
any income year and is eligible to carry forward a capital loss of SubGroup from
a prior income year to the current income year, the Separate Taxable Gains of
SubGroup shall be reduced by such capital loss.

                  (e) SubGroup's liability to Parent for payment of SubGroup's
Separate Tax Liability shall accrue: (i) with respect to SubGroup's Separate
Taxable Income, ratably during each income year, and (ii) with respect to
SubGroup's Separate Taxable Gains, as of the date of the transaction which gave
rise to each such Separate Taxable Gain. Notwithstanding



                                       -4-

<PAGE>



anything to the contrary in the foregoing, payment shall be made at such times
and in such manner as is set forth in Section 2.7 below.

                  2.3      Credit for Separate Tax Loss

                  (a) To the extent that SubGroup has Separate Tax Loss during
any income year, the Parent shall accrue for the account of SubGroup an amount
equal to the tax benefit attributable to such Separate Tax Loss that SubGroup
would have realized if SubGroup had filed its own separate consolidated federal
return during the current income year and SubGroup had been able to utilize such
tax benefit as the result of the carryback of such Separate Tax Loss to an
income year in which SubGroup had Separate Taxable Income, but only if and to
the extent that such Separate Taxable Income was generated during the period
SubGroup was a member of the Group. If SubGroup is not able to utilize the tax
benefit attributable to such Separate Tax Loss due to the absence of any
Separate Taxable Income in prior years to which SubGroup could carryback such
Separate Tax Loss, Parent shall accrue for the account of SubGroup an amount
equal to the tax benefit attributable to such Separate Tax Loss for a subsequent
tax year during which SubGroup has Separate Taxable Income to which such tax
benefit could be carried over.

                  (b) Notwithstanding that SubGroup has Separate Tax Loss during
any income year, SubGroup shall be liable for payment to the Parent of an amount
equal to SubGroup's Separate Tax Liability accrued during such year with respect
to its Separate Taxable Gains to the extent such Separate Taxable Gains are not
offset by such Separate Tax Loss.



                                       -5-

<PAGE>



                  (c) Parent's liability to SubGroup for payment of credits for
federal income tax purposes for Separate Tax Loss shall accrue ratably during
each income year in which such credit is accrued.

                  2.4      Tax Credits

                  If SubGroup has any tax credits which for federal income tax
purposes can be applied against its Separate Tax Liability, the Parent shall
credit the account of SubGroup.

                  2.5      Applicable Tax Rates

                  The Separate Tax Liability of SubGroup will be computed
pursuant to Section 2.2 by applying the then-appropriate corporate tax rates for
its computed Separate Taxable Income and Separate Taxable Gains. Any tax
adjustments necessitated by this method of allocation to ensure that the sum of
tax charges/credits is equal to the tax liability of the Group will be borne by
the Parent.
                  2.6      Alternative Minimum Tax

                  Notwithstanding the provisions of Sections 2.2 and 2.3 of this
Agreement, in the event that the Group must pay the federal alternative minimum
tax pursuant to Code Section 55, SubGroup will be charged by the Parent with its
separate share of the total alternative minimum tax liability of the Group that
reflects the alternative minimum taxable income resulting from the federal
alternative minimum tax attributes of SubGroup based upon the Separate
Alternative Minimum Taxable Income calculated for SubGroup.

                  2.7      Payment of Tax Liability; Security for Payment

                  SubGroup shall pay to Parent the amount of its Separate Tax
Liability, as determined and accrued under Section 2.2 of this Agreement,
including payment of any



                                       -6-

<PAGE>



estimated tax due with respect thereto within 20 days upon request by the Parent
but in any event no later than March 15, June 15, September 15, and December 15
of each income year. Such payment requests are intended but are not required to
support the federal income tax payments required to be made by the Parent. The
Parent will make such payments of any federal income tax as shall be due
throughout the income year on the days provided for payment of such tax,
including installments of estimated federal income taxes due pursuant to Code
Section 6655.

                  2.8      Payment of Tax Benefits

                  The Parent shall pay SubGroup any amounts accrued under
Section 2.3 and 2.4 of this Agreement the later of: (i) thirty (30) days after
the Parent files with Internal Revenue Service a consolidated federal tax
return, amended return or refund claim in which tax benefit attributable to
SubGroup is actually utilized to provide a tax savings to the Group or (ii) when
the SubGroup would, under a separate return calculation, be able to utilize the
tax benefit. The amount due and payable to SubGroup shall not exceed the amount
of such tax savings actually utilized by the Group as a result of such filing.

                  2.9      Adjustment of Consolidated Federal Tax Liability

                  In the event that for any reason there is an adjustment to the
Group's federal income tax liability, the consolidated tax liability of each
member shall be recomputed in accordance with the provisions of this Agreement
to reflect such adjustment. In the event of any overpayment of tax by SubGroup
as determined as a result of such adjustment, the Parent shall make payment to
SubGroup for the amount of the overpayment within ten (10) days after the
determination of such overpayment. However, if the overpayment of tax results in
a refund of



                                      -7-

<PAGE>



tax from the Internal Revenue Service, the Parent shall make payment to SubGroup
for its share of such refund, including interest, within ten (10) days after
receipt of the refund by the Parent. In the event of an underpayment of tax by
SubGroup as determined as a result of such adjustment, SubGroup shall pay to the
Parent its allocable share of such increased tax liability and any penalties,
additions to tax or interest within a reasonable time, but no later than thirty
(30) days after receiving notice of such liability from the Parent.

                  2.10     Indemnification

         To the extent not inconsistent with the foregoing provisions of this
Agreement, and solely regarding federal and state taxes the Parent shall
indemnify and save the SubGroup harmless from any and all claims, demands,
actions (including federal or state tax liens, levies, audits, investigations
and assessments), interest, penalties, causes of action, suits, proceedings,
damages, liabilities, and costs and expenses of every nature whatsoever arising
therefrom (collectively a "Claim" or "Claims") that arise from the conduct
and/or tax positions taken by the Parent after the date of this Agreement.

                                    ARTICLE 3

                                 ADMINISTRATIVE

shall nonetheless be given effect with respect to any tax liability, payment or

                  (c) Any balance in the Consolidated Federal Tax Receivable
Account of SubGroup shall be carried forward (but shall not be carried back) to
offset amounts Subsequently accrued in SubGroup's Consolidated Federal Tax
Payable Account during SubGroup's "carryforward period" specified in Code
