         B.       Purchaser desires to purchase and Seller desires to sell
certain assets related to the Business upon the terms and conditions set forth
below in this Agreement.

         NOW THEREFORE, in consideration of the foregoing, and the mutual
agreements, covenants, representations and warranties contained in this
Agreement, the receipt and sufficiency of which are hereby acknowledged, the
Parties hereby agree as follows:


                                   ARTICLE 1
                          PURCHASE AND SALE OF ASSETS

         1.1      PURCHASE AND SALE. On the terms and subject to the conditions
of this Agreement, Purchaser shall purchase and Seller shall sell, assign,
transfer, convey and deliver to Purchaser, at Closing, those assets of Seller
used in the operation of the Business and listed on SCHEDULE 1.1 hereto (the
"PURCHASED ASSETS").

         1.2      PURCHASE PRICE; PAYMENT. The aggregate purchase price (the
"PURCHASE PRICE") to be paid by Seller to Purchaser for assumption of the
Purchased Assets and the Assumed Liabilities (as hereinafter defined) is TWO
THOUSAND FOUR HUNDRED AND SIXTY TWO AND 63/100 DOLLARS ($2,462.63).

         1.3      ASSUMPTION OF LIABILITIES. At Closing, Purchaser shall assume
the liabilities and obligations of Seller set forth in SCHEDULE 1.2 hereto
("Assumed Liabilities"), except for: (1) liability for unpaid wages under the
Fair Labor Standards Act from the period beginning with the workweek April 16,
1998 through the workweek ending July 22, 2000; and (2) liability for return
commissions on flood insurance policies (issued between December 1, 1999 and
July 31, 2000) that were cancelled by insureds between the period of time that
begins on August 1, 2000 and ends on July 31, 2001 and that were written under
the agent account numbers listed in SCHEDULE 1.3.


                                   ARTICLE 2
                         COVENANTS REGARDING EMPLOYEES

         2.1      SELLER'S EMPLOYEES. All of the employees of Seller who are in
employment status on the day immediately prior to the Closing (the "AFFECTED

and immediately thereafter shall be offered employment by Purchaser under terms
that recognize prior employment with Seller and its affiliated entities for
purposes of all benefit plans, programs, arrangements or other seniority-based
programs or benefits maintained by Purchaser on and after the Closing Date for
the benefit of the Affected Employees. The term "EMPLOYMENT STATUS" includes

ensuring payment of claims incurred on or prior to the Closing Date under any
employee benefit programs in which Seller participates with respect to the
Affected Employees, in accordance with the terms and conditions of such
programs. A claim is "INCURRED" on the date the service or property that gives
rise to the claim is rendered or furnished, without regard to when the
individual who receives the service is billed.

         2.3      EMPLOYEE PLANS. Effective as of the Closing Date, the
Purchaser shall assume the reserves corresponding to Seller's vacation and sick
pay plans for each Affected Employee, and shall permit the Affected Employees
