         6.1 Claims Procedure. The Bank shall notify in writing any person or
entity making a claim under this Split Dollar Agreement (the "Claimant') of his
or her eligibility or ineligibility for benefits under this Split Dollar

provisions of this Split Dollar Agreement on which denial is based, (c) a
description of any additional information or material necessary for the Claimant
to perfect his or her claim, and a description of why it is needed, and (d) an
explanation of this Split Dollar Agreement's claims review procedure and other

she is entitled to greater or different benefits, the Claimant shall have the
opportunity to have his or her claim reviewed by the Bank by filing a petition

issued by the Bank. The Claimant's petition shall state the specific reasons the
Claimant believes entitle him or her to benefits or to greater or different
benefits. Within 60 days after the Bank's receipt of the petition, the Bank
shall give the Claimant (and counsel, if any) an opportunity to present his or
her position to the Bank verbally or in writing, and the Claimant (or counsel)
shall have the right to review the pertinent documents. The Bank shall notify
the Claimant of the Bank's decision in writing within the 60-day period, stating
specifically the basis of its decision and identifying the specific provisions
of this Split Dollar Agreement on which the decision is based. If, because of
the need for a hearing, the 60-day period is not sufficient, the decision may be
deferred for up to another 60-day period at the election of the Bank, but notice
of this deferral must be given to the Claimant.

                                    ARTICLE 7

                                  MISCELLANEOUS

         8.1 Binding Effect. This Split Dollar Agreement shall bind the
____________ Irrevocable Insurance Trust and the Bank and their beneficiaries,
survivors, executors, administrators and transferees, and any Policy
beneficiary.

         8.2 No Guarantee of Employment. This Split Dollar Agreement is not an
employment policy or contract. It does not give the Executive the right to
remain an 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.

         8.3 Successors; Binding Agreement. By an assumption agreement in form
and substance satisfactory to the Executive, the Bank shall require any
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 Split Dollar Agreement in the same
manner and to the same extent that the Bank would be required to perform this
Split Dollar Agreement if no succession had occurred. The Bank's failure to
obtain such an assumption agreement before succession becomes effective shall be
considered a breach of the Split Dollar Agreement and shall entitle the
Executive to the Change-in-Control Benefits payable under Section 2.4 of the
Salary Continuation Agreement between the Bank and the Executive of even date
herewith.

         8.4 Applicable Law. The Split Dollar Agreement and all rights hereunder

entire agreement between the Bank and the Executive concerning the subject
matter hereof. No rights are granted to the Executive and/or the ____________
Irrevocable Insurance Trust under this Split Dollar Agreement other than those
specifically set forth herein.

         8.6 Administration. The Bank shall have powers which are necessary to
administer this Split Dollar Agreement, including but not limited to the power

                Dollar Agreement,

         8.7 Named Fiduciary. The Bank shall be the named fiduciary and plan
administrator under this Split Dollar Agreement. The Bank may delegate to others
certain aspects of management and operational responsibilities, including the
employment of advisors and the delegation of ministerial duties to qualified
individuals.

         8.8 Severability. If for any reason any provision of this Split Dollar
Agreement is held invalid, such invalidity shall not affect any other provision
of this Split Dollar Agreement not held so invalid, and each such other
provision shall, to the full extent consistent with the law, continue in full
force and effect. If any provision of this Split Dollar Agreement shall be held
invalid in part, such invalidity shall in no way affect the remainder of such
provision, not held so invalid, and the remainder of such provision, together
with all other provisions of this Split Dollar Agreement shall, to the full
extent consistent with the law, continue in full force and effect.

         8.9 Headings. The headings of Sections herein are included solely for
