                                      FEES

Fees for failures as defined above will be assessed as follows.

1.  Non-timely failures and access unavailable will result in a deduction to the
    outstanding loan amount due IMSG of $100 per day per policy for all Fees
    applicable to each policy.

    IMSG of $100 per policy not to exceed $100 per day per policy for all Fees
    applicable to each policy.

3.  Non-compliance will result in a deduction to the outstanding loan amount due
    IMSG of $1000 per day.

4.  Any penalties, late fees, etc., assessed ICAT from local, state or federal
    agencies will result in a deduction to the outstanding loan amount due IMSG
    for the amount assessed if such penalties, late fees, etc., were caused by
    IMSG as a result of not performing under the Interim Services Agreement.

5.  In the event that Fees reach $10,000 in the aggregate, all subsequent Fees
    will double in amount.

6.  In the event IMSG incorrectly returns policy fees and/or inspection fees,
    IMSG will reimburse ICAT for the fees incorrectly returned. IMSG shall have
    no right against ICAT, its Producers, or its policyholders to recover such
    fees.

    the first $1,000 of Fees incurred by IMSG, per month, shall be waived and
    forgiven.

monthly report summarizing the failures and Fees to be offset against the
outstanding loan.

Collateral and Proceeds; (ii) not to sell, hypothecate or otherwise dispose of

(iii) at IMS's request, notify any account debtors or any other persons of
IMS's interest in the Collateral and Proceeds; (iv) to provide any reasonable

         8.       Powers of IMS. ICAT appoints IMS its true attorney in fact to
perform any of the following powers, which are coupled with an interest, are
irrevocable until termination of this Agreement and may be exercised from time
to time by IMS's officers and employees, or any of them, at any time ICAT is in
default: (a) to perform any obligation of ICAT hereunder in ICAT's name or
otherwise; (b) to liquidate any time deposit pledged to IMS hereunder prior to
its maturity date and to apply the proceeds thereof to payment of the
indebtedness, notwithstanding the fact that such liquidation may give rise to
penalties for early withdrawal of funds; (c) to notify any person obligated on
any security, instrument or other document subject to this Agreement of IMS's
rights hereunder; (d) to demand and to collect by legal proceedings or
otherwise all interest, principal or other sums now or hereafter payable upon

reorganization, deposit, merger or consolidation agreement, or any other
agreement relating to or affecting the Collateral or Proceeds, and in
connection therewith to deposit or surrender control of the Collateral and
Proceeds, accept other property in exchange for the Collateral or Proceeds, and
do and perform such other acts and things as IMS may deem proper, and any money
or property received in exchange for the Collateral or Proceeds may be applied
to the indebtedness or held by IMS under this Agreement; (f) to make any
compromise or settlement IMS deems desirable or proper in respect of the
Collateral and Proceeds; and (g) to protect and preserve the Collateral and

         9.       IMS's Care and Delivery of Collateral. IMS's obligation with

Collateral and Proceeds, and



                                  Page 19 of 24

                                                                     EJK     CB
                                                                    ----    ---
                                                                    ICAT    IMS



<PAGE>   20

such duty shall not include any obligation to ascertain or to initiate any
action with respect to or to inform ICAT of maturity dates, conversion, call or
exchange rights, or offers to purchase the Collateral or Proceeds, or any
similar matters, notwithstanding IMS's knowledge of the same. IMS shall have no
duty to take any steps necessary to preserve the rights of ICAT against prior
parties, or to initiate any action to protect against the possibility of a
decline in the market value of the Collateral or Proceeds. IMS shall not be
obligated to take any action with respect to the Collateral or Proceeds
requested by ICAT, unless such request is made in writing, and IMS determines,
in its sole discretion, that the requested action would not reasonably
jeopardize the value of the Collateral or Proceeds as security for the
indebtedness. IMS may at any time deliver the Collateral and Proceeds, or any
part thereof, to ICAT, and the receipt thereof by ICAT shall be a complete and
full acquittance for the Collateral and Proceeds so delivered, and IMS shall
thereafter be discharged from any liability or responsibility therefor.

         10.      Events of Default. The occurrence of any of the following
shall constitute an "Event of Default" under this Agreement: (a) any default in
the payment or performance of any Obligation; (b) any representation or
warranty made by ICAT herein shall prove to be at any time incorrect in any
material respect; (c) any sale or transfer of all or a substantial or material
part of ICAT's assets other than in the ordinary course of business; or (d) a
default shall occur under any of the Loan Documents.

         11.      Remedies.

                  (a)      Upon the occurrence of any Event of Default, IMS
shall have the right to declare immediately due and payable all indebtedness
secured hereby and to terminate any commitments to make loans or otherwise
extend credit to ICAT without presentment, demand, protest or notice of
dishonor, all of which are expressly waived by ICAT. IMS shall have all other
rights, privileges, powers and remedies granted to a secured party upon default
under the Code or otherwise provided by law, including without limitation the
right to contact any persons obligated to ICAT on Collateral and to instruct
such persons to deliver all Proceeds directly to IMS. The rights, privileges,
powers and remedies of IMS shall be cumulative. No delay, failure or
discontinuance of IMS in exercising any right, power, privilege or remedy shall
affect or operate as a waiver of such right, power, privilege or remedy; nor
shall any single or partial exercise of any right, power, privilege or remedy
preclude, waive or otherwise affect any other or further exercise thereof or
the exercise of any other right, power, privilege or remedy. Any waiver,
permit, consent or approval of any kind by IMS of any default hereunder, or



                                  Page 20 of 24

                                                                     EJK     CB
                                                                    ----    ---
                                                                    ICAT    IMS

<PAGE>   21

any such waiver of any provisions or conditions hereof, must be in writing and
shall be effective only to the extent set forth in writing.

                  (b)      While ICAT is in default: (i) IMS may, at any time
and at IMS's sole option, liquidate any time deposits pledged to IMS hereunder,
whether or not said time deposits have matured and notwithstanding the fact
that such liquidation may give rise to penalties for early withdrawal of funds;
(ii) IMS may appropriate the Collateral and apply all Proceeds toward repayment
of the indebtedness in such order of application as IMS may from time to time
elect or, at IMS's sole option, place any Proceeds in the cash collateral
account; and (iii) ICAT will assemble and deliver all Collateral and Proceeds,
and books and records pertaining thereto, to IMS at a reasonably convenient
place designated by IMS.


         12.      Disposition of Collateral and Proceeds. Any proceeds of any
disposition of any of the Collateral or Proceeds, or any part thereof, may be
applied by IMS to the payment of expenses incurred by IMS in connection with
the foregoing, including reasonable attorneys' fees, and the balance of such
proceeds may be applied by IMS toward the payment of the indebtedness and in
such order of application as IMS may from time to time elect.

         13.      Further Assurances and Power of Attorney. ICAT will execute
and deliver to IMS, at IMS's request, at any time and from time to time, such
financing statements and other instruments (and pay the cost of filing or
recording the same in all public offices reasonably deemed necessary or
desirable by IMS) and do such other acts and things as IMS may reasonably deem
necessary or desirable in order to establish, maintain and perfect a valid
security interest in the Collateral and Proceeds in favor of IMS (free and
clear of all other security interests, liens, charges, encumbrances and other
claims, whether voluntarily or involuntarily created, except as permitted
herein including without limitation as noted in Paragraph 3, "Subordination",
hereof) or in order to facilitate the collection of the Collateral.

         14.      ICAT Remains Liable. Anything herein to the contrary
notwithstanding: (a) ICAT shall remain liable for under the contracts and
agreements contained in the Collateral to the extent set forth therein to
perform all of its duties and obligations thereunder to the same extent as if
this Agreement had not been executed; (b) the exercise by IMS of any of its
rights hereunder shall not release ICAT from any of its duties or obligations
under the contracts and agreements included in the Collateral; and (c)

<PAGE>   22

IMS shall not have any obligation or liability under the contracts and
agreements included in the Collateral by reason of this Agreement, nor shall
IMS be obligated to perform any of the obligations or duties of ICAT thereunder
or to take any action to collect or enforce any claim for payment assigned
hereunder.

         15.      Costs, Expenses and Attorneys' Fees. ICAT shall reimburse IMS
for all payments, advances, charges, costs and expenses, including reasonable
attorneys' fees, made or incurred by IMS in exercising any right, power,
privilege or remedy conferred by this Agreement or in the enforcement thereof,
including any of the foregoing incurred in connection with any bankruptcy
proceeding relating to ICAT, including without limitation the seeking of relief
from or modification of the automatic stay, the negotiation and drafting of a
cash collateral order, or any proceeding in bankruptcy relating to the
valuation of the Collateral and/or Proceeds. All of the foregoing shall be paid
to IMS by ICAT immediately and without demand, together with interest at a rate
of seven and one half (7 1/2) percent per annum.

         16.      Notices. All notices or demands of any kind which IMS may be
required or desires to serve upon ICAT under the terms of this Agreement shall
be served upon ICAT in accordance with Article 7 of the Policy Administration
Agreement, as amended by the Addendum.

         17.      Successors, Assigns; Governing Law. This Agreement shall be
binding upon and inure to the benefit of the heirs, executors, administrators,
legal representatives, successors and assigns of the parties, and shall be
governed by and construed in accordance with the laws of the State of New York.
Any dispute arising out of or relating to this Agreement shall be resolved in
accordance with Article 6 of the Policy Administration Agreement.

         18.      Severability of Provisions. If any provision of this
Agreement shall be held to be prohibited by or invalid under applicable law,
such provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or any
remaining provision of this Agreement.

         19. Controlling Agreement. To the extent that this Agreement conflicts
with or is in any way incompatible with any other Loan Document concerning the
Obligations, the Note shall control over any other Loan Document, and if the
Note does not address an issue, then each other Loan Document shall control to
the extent that it deals most specifically with an issue.
