                                    ARTICLE 2
                           POLICY OWNERSHIP/INTERESTS

        2.1     Bank Ownership. The Bank is the sole owner of the Policy and
shall have the right to exercise all incidents of ownership. The Bank shall be
the beneficiary of the remaining death proceeds of the Policy after the
Executive Interest has been paid according to Section 2.2 below.

        2.2     Executive's Interest. The Executive shall have the right to
designate the beneficiary of the Executive's Interest. If at the time of
Termination of Employment the Executive is entitled to benefits under the Salary
Continuation Agreement in effect at the time of Termination of Employment, or if
Termination of Employment occurs because of the Executive's death (except under
Section 5.2 of the Salary Continuation Agreement), then the beneficiary
designated in accordance with the Split Dollar Policy Endorsement shall be
entitled to an amount (the Executive's Interest) equal to the product of (a)
100% of the Net Death Proceeds multiplied by (b) the percentage in which the
Executive is vested under the Salary Continuation Agreement (which shall be
deemed to be 100% in any case in which benefits under the Salary Continuation
Agreement are determined without regard to vesting). Without limiting the
generality of the foregoing, the Executive shall be considered to be 100% vested
under the Salary Continuation Agreement if Termination of Employment occurs
because of Disability, or if benefits are payable under Section 2.4 of the
Salary Continuation Agreement because of Termination of Employment within 12
months after a Change in Control, or if the Executive has become 100% vested
under Section 1.17 of the Salary Continuation Agreement, or if the Executive
dies in active service to the Bank.

        The Executive or the Executive's transferee shall also have the right to
elect and change settlement options that may be permitted for the Executive's
Interest.

        2.3     Option to Purchase. Upon termination of this Agreement, the Bank
shall not sell, surrender or transfer ownership of the Policy without first
giving the Executive or the Executive's transferee the option to purchase the
Policy for a period of 60 days from written notice of such intention. The
purchase price shall be an amount equal to the cash surrender value of the
Policy.

        2.4     Comparable Coverage. The Bank may replace the Policy with a
comparable insurance policy to cover the benefit provided under this Agreement,
in which case the Bank and the Executive shall execute a new Split Dollar Policy
Endorsement for the comparable insurance policy.

        2.5     Internal Revenue Code Section 1035 Exchanges. The Executive
recognizes and agrees that the Bank may after this Split Dollar Agreement is
adopted wish to exchange the Policy of life insurance on the Executive's life
for another contract of life insurance insuring the Executive's life. Provided
that the Policy is replaced (or intended to be replaced) with a comparable
policy of life insurance, the Executive agrees to provide medical information
and cooperate with medical insurance-related testing required by a prospective
insurer for implementing the Policy or, if necessary, for modifying or updating
to a comparable insurer.

                                    ARTICLE 3
                                    PREMIUMS

        3.1     Premium Payment. The Bank shall pay any premiums due on the
Policy.

        3.2     Economic Benefit. The Administrator shall annually determine the
economic benefit attributable to the Executive based on the amount of the
current term rate for the Executive's age multiplied by the aggregate death
benefit payable to the Executive's beneficiary. The current term rate is the
minimum amount required to be imputed under applicable Internal Revenue Service
authority.

                                       291
<PAGE>

        3.3     Imputed Income. The Bank shall impute the economic benefit to
the Executive on an annual basis.

                                    ARTICLE 4
                                   ASSIGNMENT

        The Executive may irrevocably assign without consideration all of the
Executive's Interest in this Agreement to any person, entity, or trust
established by the Executive or the Executive's spouse. If the Executive
transfers all of the Executive's Interest, then all of the Executive's Interest
in the Agreement shall be vested in the Executive's transferee, who shall be
substituted as a party hereunder and the Executive shall have no further
interest in this Agreement.

                                    ARTICLE 5
                                     INSURER

        The Insurer shall be bound only by the terms of the Policy. Any payments
the Insurer makes or actions it takes in accordance with the Policy shall fully
discharge it from all claims, suits and demands of all entities or persons. The
Insurer shall not be bound by or be deemed to have notice of the provisions of
this Agreement.

                                    ARTICLE 6
                          CLAIMS AND REVIEW PROCEDURES

                6.1.2   Timing of Administrator Response. The Administrator
        shall respond to such claimant within 90 days after receiving the claim.
        If the Administrator determines that special circumstances require

        the response period by an additional 90 days by notifying the claimant
        in writing, prior to the end of the initial 90-day period, that an
        additional period is required. The notice of extension must set forth
        the special circumstances and the date by which the Administrator
        expects to render its decision.

                6.1.3   Notice of Decision. If the Administrator denies part or
        all of the claim, the Administrator shall notify the claimant in writing
        of such denial. The Administrator shall write the notification in a
        manner calculated to be understood by the claimant. The notification
        shall set forth:

        (a)     The specific reasons for the denial,

<PAGE>

        (c)     A description of any additional information or material
                necessary for the claimant to perfect the claim and an
                explanation of why it is needed,
        (d)     An explanation of the Agreement's review procedures and the time

                under ERISA section 502(a) following an adverse benefit
                determination on review.

        6.2     Review Procedure. If the Administrator denies part or all of the
claim, the claimant shall have the opportunity for a full and fair review by the
Administrator of the denial, as follows:

                6.2.1   Initiation - Written Request. To initiate the review,
        within 60 days after receiving the Administrator's notice of denial the
        claimant must file with the Administrator a written request for review.

                6.2.2   Additional Submissions - Information Access. The
        claimant shall then have the opportunity to submit written comments,
        documents, records and other information relating to the claim. Upon
        request and free of charge, the Administrator shall also provide the
        claimant reasonable access to, and copies of, all documents, records and
        other information relevant (as defined in applicable ERISA regulations)
        to the claimant's claim for benefits.

                6.2.3   Considerations on Review. In considering the review, the
        Administrator shall take into account all materials and information the
        claimant submits relating to the claim, without regard to whether such
        information was submitted or considered in the initial benefit
        determination.

                6.2.4   Timing of Administrator Response. The Administrator
        shall respond in writing to such claimant within 60 days after receiving
        the request for review. If the Administrator determines that special
        circumstances require additional time for processing the claim, the
        Administrator can extend the response period by an additional 60 days by
        notifying the claimant in writing, prior to the end of the initial
        60-day period, that an additional period is required. The notice of
        extension must set forth the special circumstances and the date by which
        the Administrator expects to render its decision.

                all documents, records and other information relevant (as
                defined in applicable ERISA regulations) to the claimant's claim
                for benefits, and

shall appoint. The Executive may be a member of the Administrator. The

        8.2     Amendment and Termination of Agreement. This Agreement may be
amended or terminated solely by a written agreement signed by the Bank and the
Executive. However, this Agreement will automatically terminate and the
Executive's Interest shall be forfeited if benefits under the Salary

successor (whether direct or indirect, by purchase, merger, consolidation, or
otherwise) to all or substantially all of the business or assets of the Bank to
expressly assume and agree to perform this Agreement in the same manner and to
the same extent that the Bank would be required to perform this Agreement if no
succession had occurred.

employee of the Bank, nor does it interfere with the Bank's right to discharge
the Executive. It also does not require the Executive to remain an employee nor
interfere with the Executive's right to terminate employment at any time.
