        WHEREAS, on the date hereof, Fiserv, Fiserv Solutions, Fiserv Sub and
the Company are entering into that certain Agreement and Plan of Merger, dated
as of even date herewith (as entered into and as the same may be modified or
amended or any of its provisions waived pursuant to the terms thereof, the
"Merger Agreement"; capitalized terms used but not defined in this Agreement

        WHEREAS, the Shareholders wish to see the Merger consummated, and have
determined the consummation of the Merger to be in the best interests of the
Shareholders; and

        WHEREAS, as a condition to the willingness of Fiserv, Fiserv Solutions
and Fiserv Sub to enter into the Merger Agreement, Fiserv, Fiserv Solutions and
Fiserv Sub have requested that the Shareholders agree, and, in order to induce
Fiserv, Fiserv Solutions and Fiserv Sub to enter into the Merger Agreement, the
Shareholders have agreed, to enter into this Agreement;

        NOW, THEREFORE, in consideration of the foregoing, and for other good
and valuable consideration, the receipt and adequacy of which is hereby
acknowledged, the parties hereto agree as follows:

1.   Vote in Favor of Merger. During the period commencing on the date hereof
     and terminating upon the earlier of the Effective Time or the termination
     of the Merger Agreement in accordance with its terms, each Shareholder, in
     its capacity as a shareholder of the Company and holder of any proxy or
     other right to cause or direct the voting of any shares of Company Common
     Stock, agrees to (a) vote all shares of Company Common Stock presently
     owned by Shareholder or any of its Affiliates or for



     which Shareholder has voting power, and all shares of Company Common Stock
     with respect to which Shareholder in the future acquires ownership or is
     otherwise granted or obtains voting power, at any meeting of the
     Shareholders of the Company (or any adjournment thereof), (i) in favor of
     the approval and adoption of the Merger Agreement and the transactions
     contemplated thereby, including without limitation the Merger; and (ii)
     against any action that could reasonably be expected to impede, interfere,
     delay, or discourage the Merger, facilitate an acquisition of the Company
     or all or substantially all of its assets or business, in any manner, by a
     party (other than Fiserv or a subsidiary of Fiserv), or result in any
     breach of representation, warranty, covenant or agreement of the Company
     under the Merger Agreement, or (b) in the event written consents are sought
     from the shareholders of the Company with respect to the actions proposed
     in (i) or (ii) above, cause to be executed, with respect to all shares of
     Company Common Stock then owned by Shareholder or as to which Shareholder
     has the power to vote or to direct the voting of, a written consent or
     written consents to such proposed action. To the extent inconsistent with
     the foregoing provisions of this Section 1, each Shareholder hereby revokes
     any and all previous proxies with respect to any shares of Company Common
     Stock that such Shareholder owns or has the right to vote. In addition,
     each Shareholder agrees not to dispose of or otherwise sell any shares of
     Company Common Stock owned by it, except to other Shareholders subject to
     this Agreement.

2.   No Solicitation. During the period commencing on the date hereof and
     terminating upon the earlier of the Effective Time or the termination of
     the Merger Agreement in accordance with its terms, each Shareholder hereby
     agrees, and agrees to use commercially reasonable efforts to cause its
     Affiliates, officers, directors, employees or consultants or agents, not to
     (a) directly or indirectly, solicit, initiate, encourage, accept or
     otherwise facilitate the making of an Acquisition Proposal, (b) participate
     or engage in or encourage in any way negotiations or discussions
     concerning, or provide any non-public information to, any person or entity
     relating to an Acquisition Proposal, or which may reasonably be expected to
     lead to an Acquisition Proposal or (c) agree to or endorse any Acquisition
     Proposal; provided, however, that nothing contained in this Section 2 or in
     any other provision of this Agreement will prohibit the Company or any
     individual who is a member of the Board of Directors of the Company from
     taking and disclosing to the Company's shareholders a position contemplated
     by Rule 14e-2 promulgated under the Exchange Act or from making any legally
     required disclosure to the Company's shareholders or to the extent
     otherwise specifically permitted by the Merger Agreement. For purposes of
     this Agreement, "Affiliate" shall mean, with respect to any person or
     entity, any person or entity that, directly or indirectly, controls, or any
     entity that is controlled by, or is under common control with that Person.

3.   Sale of Shares held by the Shareholders and their Affiliates. The
     Shareholders agree that, as provided in the Merger Agreement, the Merger
     Consideration to be paid pursuant to the Merger Agreement for all of the
     shares of Company Common Stock held by the Shareholders and their
     Affiliates that are not individuals shall be $3.26 per share, in cash,
     without interest.

4.   Limited Indemnification and Release. BIG will indemnify the Indemnitees (as
     hereinafter defined) in accordance with the terms set forth on Schedule 4
     attached hereto.

                                       2



     Each of the Shareholders grants the release set forth on Schedule 4
     attached hereto.

5.   Non-Competition. Each Shareholder, on behalf of itself and each of its
     current and future subsidiaries or Affiliates, covenants and agrees from
     the Effective Time (except with respect to clause (b), as qualified by
     clause (ii), from the date hereof) until the third anniversary of the
     Effective Time (the "Non-Competition Period") not to, directly or
     indirectly, (a) engage or invest in, or have any competitive business
     relationship with, either as an owner, partner, agent, consultant, creditor
     or otherwise, any business or commercial activity relating to the
     processing of flood insurance in the United States or (b) solicit, hire,
     cause to be hired, engage the services of or otherwise enable, encourage or
     assist, directly or indirectly, any persons which they knew or reasonably
     should know are employees of the Company or any persons who are employees
     of Fiserv or its subsidiaries with whom they came into contact in
     connection with the transactions contemplated hereby to terminate their
     employment with the Company or Fiserv or its Affiliate, as the case may be.
     Notwithstanding the foregoing, either BIG or any other Shareholder may (i)
     own capital stock in a publicly-traded company not to exceed 1% of the
     outstanding capital stock of such company and (ii) solicit or hire any such
     IT personnel of the Company as are agreed to in writing by the Company and
     such Shareholder prior to the Effective Time. Each of Fiserv, Fiserv
     Solutions and Fiserv Sub, on behalf of itself and each of its current and
     future subsidiaries or Affiliates, covenants and agrees that during the
     Non-Competition Period, they shall not solicit, hire, cause to be hired or
     otherwise enable, encourage or assist, directly or indirectly, any persons
     which they know or reasonably should know are employees of the
     Shareholders. Each party agrees that the foregoing limitations are
     reasonable in time and scope. Each party's obligations pursuant to this
     Section 5 shall arise only if the Merger becomes effective (except with
     respect to clause (b), as qualified by clause (ii), which shall be
     effective from the date hereof) and then such obligations shall survive for
     the Non-Competition Period. If the transactions contemplated by the Merger
     Agreement are abandoned in accordance with the Merger Agreement, the
     agreement set forth in this Section 5 shall terminate immediately upon such
     abandonment.

6.   Representations and Warranties of the Shareholders. Each of the
     Shareholders represents and warrants to Fiserv, Fiserv Solutions and Fiserv
     Sub that: (i) each such Shareholder has the legal capacity to enter into
     and perform all of its respective obligations under this Agreement; (ii)
     the execution, delivery and performance of this Agreement by each such
     Shareholder will not violate any other agreement to which such Shareholder
     is a party, including, without limitation, any voting agreement,
     shareholders agreement or voting trust; (iii) this Agreement has been duly
     executed and delivered by each such Shareholder and constitutes a legal,
     valid and binding agreement of each such Shareholder, enforceable against
     it in accordance with its terms; (iv) each such Shareholder owns
     beneficially, and has full voting power with respect to, the shares of
     Company Common Stock that it is making its agreement with respect to under
     Section 1 hereof, other than shares beneficially owned by Affiliates over
     which such Shareholder does not have voting power, and; (v) no shares of
     Company Common Stock held by such Shareholder are subject to any voting
     agreement other than this Agreement.

7.   Officer and Director Insurance. After the Effective Time, Fiserv shall take
     all actions to

                                       3



     ensure that the Surviving Corporation complies with its obligations set
     forth in Section 6.17 of the Merger Agreement. To the extent not paid prior
     to the Effective Time, Fiserv shall cause the Surviving Corporation to pay
     half the premium for any "tail coverage" policy acquired, and BIG agrees to
     pay the other half of the premium for any such "tail coverage" policy
     acquired plus any premium payable in respect of naming BIG as an additional
     insured under such policy.

8.   Successors and Assigns. Neither this Agreement nor any of the rights,
     interests or obligations hereunder shall be assigned by any of the parties
     hereto (whether by operation of law or otherwise) without the prior written
     consent of the other parties, except that any Shareholder may transfer
     shares of Company Common Stock, together with its rights, interests and
     obligations hereunder to BIG or any direct or indirect wholly owned
     subsidiary of BIG; provided, however, that no such assignment shall relieve
     any party of its obligations hereunder; and provided, further, however,
     that, at the Effective Time upon consummation of the Merger, by operation
     of law, the Surviving Corporation shall succeed to Fiserv Sub's rights
     hereunder. Subject to the preceding sentence, this Agreement will be
     binding upon, inure to the benefit of and be enforceable by the parties and
     their respective successors and assigns.

9.   Specific Performance. The parties hereto agree that irreparable damage
     would occur in the event any provision of this Agreement is not performed
     according to its specific terms and that the parties shall be entitled to
     seek specific performance of the terms hereof, in addition to any other
     remedy at law or in equity. The parties agree that in the event any or all
     of the Shareholders do not perform in full their obligations under Sections
     1 and 2 hereof, BIG shall pay Fiserv (the "Vote Fee"), in consideration of
     the considerable effort and expense Fiserv has incurred in connection with
     the transactions contemplated under this Agreement, $1,200,000 payable upon
     the termination of the Merger Agreement; provided, however that (a) the
     Vote Fee will not be owed to Fiserv by BIG in the event that (i) the Fee is
     payable by the Company pursuant to the terms of the Merger Agreement or
     (ii) the approval of shareholders has been obtained in accordance with
     Section 7.01(b) of the Merger Agreement, and (b) the Fee under the Merger
     Agreement shall not be owed by the Company at any time after the Vote Fee
     has been paid by BIG.

10.  Counterparts. This Agreement may be executed in any number of counterparts,
     each of which shall be deemed to be an original and all of which together
     shall constitute one and the same document.

11.  Further Assurances. Each of the Shareholders shall execute and deliver such
     additional documents and take such further action as may be necessary or
     desirable to consummate the transactions contemplated by this Agreement.

12.  Third-Party Beneficiaries. Nothing in this Agreement, expressed or implied,
     shall be construed to give any person other than the parties hereto any
     legal or equitable right, remedy, or claim under or by reason of this
     Agreement or any provision contained herein.

13.  Governing Law. This Agreement shall be governed by and construed in
     accordance with the laws of the State of Florida applicable to contracts
     made and to be performed therein.

                                       4



14.  Jurisdiction and Venue. The parties agree that any proceeding relating to
     this Agreement shall be brought in a court of Florida. Each of the parties
     consents to personal jurisdiction in any such action brought in any such
     Florida court, consents to service of process by registered mail made upon
     such party and such party's agent, and waives any objection to venue in any
     such Florida court or to any claim that any such Florida court is an
     inconvenient forum. The prevailing party in any suit or action brought
     against any other party to enforce the terms of this Agreement or any
     rights or obligations hereunder shall be entitled to receive reimbursement
     of its costs, expenses and attorneys' fees (internal and external) and
     disbursements, including the costs and expenses of experts and internal
     resources expended, actually incurred in connection with such suit or
     action.

15.  No Amendment of Merger Agreement. Fiserv, Fiserv Solutions and Fiserv Sub
     shall not amend the Merger Agreement without the prior written consent of
     BIG, which consent shall not be unreasonably withheld.

16.  Payment for Shares. At the Effective Time, (a) each of the Shareholders and
     their Affiliates shall surrender their Company Certificates representing
     all shares of Company Common Stock held by the Shareholders or their
     Affiliates and (b) Fiserv shall pay to each Shareholder or their
     Affiliates, as the case may be, by wire transfer cash in the amount of
     $3.26 per share of Company Common Stock represented by each Shareholder's
     Company Certificates to such accounts as are designated by such
     Shareholders or their Affiliates.

17.  Termination. This Agreement shall terminate upon the earlier of the
     Effective Time or termination of the Merger Agreement in accordance with
     its terms; provided, however, that the provisions of Section 4, Section 5,
     Section 6, Section 7, Section 8, Section 9, Section 10, Section 11, Section
     12, Section 13, Section 14 and this Section 17 shall continue in effect
     following the Effective Time in accordance with the respective provisions
     thereof, and the provisions of Section 9 and Section 14 shall continue in
     effect following the termination of the Merger Agreement.

                                       5



     IN WITNESS WHEREOF, each of Fiserv, Fiserv Solutions and Fiserv Sub, on the
