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’s interest is paid according to section 2.2 below.

2.2 Death Benefit.

The Executive’s Interest shall be extinguished at the earliest of the date of the Executive’s Separation from Service, the date the Executive attains age 60, or the date on which the Executive receives payment of the benefit provided under the Salary Continuation Agreement for a Change in Control, and the Executive’s beneficiary shall be entitled to no benefits under the Agreement of the Executive’s death occurring thereafter.

2.5 Internal Revenue Code Section 1035 Exchanges. The Executive recognizes and agrees that the Bank may after this 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.

ARTICLE 3

PREMIUMS

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

3.2 Economic Benefit.

CLAIMS AND REVIEW PROCEDURES

6.1 Claims Procedure. The Bank will notify any person or entity that makes a claim for benefits under this Agreement (the “claimant”) in writing, within 90 days after receiving claimant’s written application for benefits, of his or her eligibility or noneligibility for benefits under the Agreement. If the Administrator determines that the claimant is not eligible for benefits or full benefits, the notice will state (w) the specific reasons for denial, (x) a specific reference to the provisions of the Agreement on which the denial is based, (y) 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 (z) an explanation of the Agreement’s claims review procedure and other appropriate information concerning steps to be taken if the claimant wishes to have the claim reviewed. If the Administrator determines that there are special circumstances requiring additional time to make a decision, the Bank will notify the claimant of the special circumstances and the date by which a decision is expected to be made, and may extend the time for up to an additional 90 days.

6.2 Review Procedure. If the claimant is determined by the Administrator not to be eligible for benefits, or if the claimant believes that he or she is entitled to greater or different benefits, the claimant will have the opportunity to have his or her claim reviewed by the Bank by filing a petition for review with the Bank within 60 days after receipt of the notice issued by the Bank. The claimant’s petition must state the specific reasons the claimant believes entitle him or her to benefits or to greater or different benefits. Within 60 days after receipt by the Bank of the petition, the Administrator will give the claimant (and counsel, if any) an opportunity to present his or her position verbally or in writing, and the claimant (or counsel) will have the right to review the pertinent documents. The Administrator will notify the claimant of the Administrator’s decision in writing within the 60-day period, stating specifically the basis of its decision, written in a manner to be understood by the claimant, and the specific provisions of the 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 days at the election of the Administrator, but notice of this deferral will be given to the claimant.
