         WHEREAS, in connection with the anticipated approval, execution and
delivery of the SparBank Merger Agreement, the Board of Directors of the Company
has adopted, in accordance with Sections 5.4 and 5.14 of the Rights Agreement, a
resolution approving this Amendment and directing the appropriate officers of

   2
         immediately precedes the parenthetical with the number "iii" inside and
         replacing said word with a comma and by adding the following language
         at the end of the first sentence of said definition:

         " . . ., or (iv) who is a Cowlin Family Member who Beneficially owns

its Affiliates or Associates at the time of the execution of the SparBank Merger
Agreement, (C) shares of Common Stock (or securities convertible into,
exchangeable into or exercisable for Common Stock) acquired by a Cowlin Family
Member or its Affiliates or Associates after the execution of the SparBank
Merger Agreement, which, in the aggregate, amount to less than 1% of the
outstanding shares of Common Stock or (D) shares of Common Stock acquired by
means of a stock dividend or stock split. For purposes of this Agreement, the
term "Cowlin Family Member" shall mean (i) Geraldine C. Cowlin, (ii) any spouse
of Geraldine C. Cowlin, (iii) any lineal descendants (including descendants by
adoption and their descendants) of Geraldine C. Cowlin or any spouse of any such
lineal descendant, (iv) any estate of, or trust established by, one or more of
the persons described in clauses (i), (ii), and (iii), provided that one or more
of the persons described in clauses (i), (ii), and (iii) or charitable
organizations which qualify as exempt organizations under Section 501(c) of the
Internal Revenue Code of 1986, as amended ("Charitable Organizations"),
collectively, are the beneficiaries of at least 50% of the
actuarially-determined beneficial interests in such estate or trust, (v) any
Charitable Organization which is established by one or more of the persons
described in clauses (i), (ii), and (iii) (a "Family Charitable Organization"),

Family Charitable Organizations."

2.       ADDITION OF SECTION 1.1. Section 1.1 of the Rights Agreement is amended
         by adding the following definitions:

         "SparBank" shall mean SparBank, Incorporated, a Delaware corporation,
         and its successors.

         "SparBank Merger Agreement" shall mean the Agreement and Plan of
         Merger, dated as of June 18, 1997, by and between SparBank and the
         Company, as the same may be from time-to-time amended.

3.       ADDITION OF SECTION 5.19. Section 5.19 is added to the Rights Agreement
         to read as follows:
   3
         "5.19 CERTAIN EVENTS. Notwithstanding any provision of this Agreement
         to the contrary, on Separation Time, Stock Acquisition Date, Flip-In
         Date or Flip-over Transaction or Event shall be deemed to have
         occurred, and no holder of Rights shall be entitled to exercise the
         Rights, solely by reason of the approval, execution, or delivery of the
         SparBank Merger Agreement, or the consummation of any transactions
         contemplated by the SparBank Merger Agreement. In the event a Cowlin
         Family Member or any of its Affiliates or Associates becomes the
         Beneficial Owner of any shares of Common Stock in a manner not
         permitted by clause (iv) of the first sentence of the definition of
         "Acquiring Person" as set forth in Section 1.1 hereof, the provisions
         of this Section shall not be applicable."

4.       EFFECTIVENESS. This Amendment shall be deemed to be in force and
         effective immediately upon execution and delivery of the SparBank
         Merger Agreement. Except as amended hereby, the Rights Agreement shall
         remain in full force and effect and shall be otherwise unaffected
         hereby.

         IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
duly executed as of this day and year first above written.
