Mr. Tapscott submitted his resignation in accordance with the Company?s Director Resignation Policy, which requires that any person serving as a director submit his or her resignation as a director upon attaining the age of 73 during his or her tenure. As such, Mr. Tapscott?s resignation is not the result of any disagreement with the Company.

Mr. Tapscott served as Chair of the Audit Committee due to his previous experience in accounting and financial matters, and also served on the Executive Committee, Loan Committee, Nominating and Corporate Governance Committee and the Risk and Insurance Committee.
