                          GUARANTY OF PAYMENT OF DEBT

     This Guaranty of Payment of Debt (the "Agreement") is made and entered into
this 31st day of July 1998, by Insurance Management Solutions Group, Inc.
("IMSG"), a Florida corporation and Bankers Insurance Group, Inc. ("BIG"), a
Florida corporation. IMSG and BIG are collectively referred to herein as the
"Guarantors."

     WHEREAS, on May 12, 1998, the Guarantors, Bankers Hazard Determination
Services, Inc. ("Bankers"), Geotrac, Inc. ("Geotrac") and Daniel J. and Sandra
White (the "Whites") entered into an Agreement and Plan of Merger (the "Merger
Agreement") pursuant to which Geotrac merged (the "Merger") with and into
Bankers with Bankers being the surviving corporation and changing its name to
Geotrac, Inc. (the "Company");

     WHEREAS, as part of the merger consideration, for their shares of Geotrac,
the Whites received a Subordinated Promissory Note in the principal amount of
$1,500,000 issued by the Company (the "Note");

     WHEREAS, as a condition to the consummation of the Merger, the Guarantors
agreed to guaranty all of the Company's obligations pursuant to or arising out
of the Note to the Whites (the "Debt");

     NOW, THEREFORE, in consideration of the foregoing premises and other
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Guarantors agree as follows:

1.   GUARANTY OF DEBT. Guarantors hereby absolutely and unconditionally, jointly
and severally, guaranty the prompt payment in full of all of the Debt as and
when the respective parts thereof become due and payable. If the Debt or any
part thereof shall not be paid in full when due and payable, the Whites in each
case shall have the right to proceed directly against either Guarantor under
this instrument to collect the payment in full of the Debt, regardless of
whether or not the Whites shall have theretofore proceeded or shall then be
proceeding against the Company or any other obligor, if any, or any of the
foregoing, it being understood that the Whites, in their sole discretion may
proceed against any obligor, and may exercise each right, power or privilege
that the Whites may then have, either simultaneously or separately, and, in any
event, at such time or times and as often and in such order as the Whites in
their sole discretion may from time to time deem expedient to collect the
payment in full of the Debt.

2.   GUARANTORS' OBLIGATIONS ABSOLUTE AND UNCONDITIONAL. Regardless of the
duration of time, regardless of whether the Company may from time to time cease
to be indebted to the Whites and irrespective of any act, omission or course of
dealing whatever on the part of the Whites, Guarantors' liabilities and other
obligations under this instrument shall remain in full effect until the payment
in full of the Debt. Without limiting the generality of the foregoing:
    

   2
   
     2.1. Guarantors' Waiver of Notice Presentment, etc. Each Guarantor waives
(a) presentment, demand for payment and notice of dishonor of the Debt or any
part thereof, or any other indebtedness incurred by the Company to the Whites,
(b) notice of any indulgence granted to any obligor and (c) any other notice to
which such Guarantor might, but for this waiver, be entitled;

     2.2. The Whites's Rights Not Prejudiced by Action or Omission. The Whites
in their sole discretion may, without any prejudice to their rights under this
instrument, at any time or times, without notice to or the consent of either
Guarantor, (a) grant the Company whatever financial accommodations that the
Whites may from time to time deem advisable, even if the Company might be in
default in any respect and even if those financial accommodations might not
constitute indebtedness the payment of which is guaranteed hereunder, (b)
assent to any renewal, extension, consolidation or refinancing of the Debt or
any part thereof, (c) release any obligor, if any, irrespective of the
consideration, if any, received therefor, (d) grant any waiver or consent or
forbear from exercising any right, power or privilege that the Whites may have
or acquire, (e) assent to any amendment, deletion, addition, supplement or
other modification in, to or of any writing evidencing or securing any Debt or
pursuant to which any Debt is created, (f) grant any other indulgence to any
obligor, (g) accept any collateral for, or any other obligor upon, the Debt or
any part thereof, and (h) fail, neglect or omit in any way to realize upon any
collateral or to protect the Debt or any part thereof or any collateral
therefor;

     2.3. Liabilities Absolute and Unconditional. Each Guarantor's liabilities
and other obligations under this instrument shall be absolute and unconditional
irrespective of any lack of validity or enforceability of the Note, or any
other agreement, instrument or document evidencing the obligations of the
Company to the Whites or related thereto, or any other defense available to
either Guarantor in respect of this instrument.

(a) such Guarantor has the corporate power and right to execute and deliver this
instrument and to perform and observe the provisions hereof and that all
requisite corporate action has been taken; (b) this instrument, when executed,
is legal and binding upon such Guarantor in every respect; (c) no litigation or
proceeding is pending or threatened against such Guarantor before any court or
any administrative agency which, in the opinion of such Guarantor's counsel, is
reasonably expected to have a material adverse effect on such Guarantor's
financial condition; (d) such Guarantor is not insolvent as defined in any
applicable state or federal statute, nor will such Guarantor be rendered
insolvent by the execution and delivery of this instrument to the Whites; and
(e) such Guarantor does not intend to, nor does such Guarantor believe that such
Guarantor will, incur debts beyond such Guarantor's ability to pay them as they

consummation of the IPO.

permitted by law, each Guarantor waives any claim or other right which either
Guarantor might now have or hereafter acquire against the Company or any other
obligor which arises from the existence or performance of either Guarantor's
liabilities or other obligations under this instrument, including, without
limitation, any right of subrogation, reimbursement, exoneration, contribution,
indemnification, and any right to participate in any claim or remedy of the
Whites against the Company whether or not such claim, remedy or right arises in
equity, or under contract, statute or common law.

Guarantor to the Whites pursuant to any of the provisions hereof shall not be

8.   MISCELLANEOUS. This instrument shall bind both Guarantors and both
Guarantors' successors and assigns and shall inure to the benefit of the Whites
