At these meetings the Company expects to discuss and update previous guidance and provide certain new information as set forth below.

The information disclosed under this Item 7.01 is being furnished and shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section, nor shall it be incorporated by reference into any registration statement or other document pursuant to the Securities Act of 1933, as amended, except as expressly set forth in such filing.

Legal Proceedings

In its report on Form 10-Q for the quarterly period ended March 31, 2009, the Company reported on a lawsuit filed on May 1, 2009 against the Company, its bank subsidiary, Mr. Gleason and another officer of the Company's bank subsidiary. The lawsuit asserts various theories of liability and seeks substantial damages. The Company and the other defendants have not yet responded to the complaint, but intend to vigorously defend the action and believe that the allegations of the complaint are wholly without merit.

As reported in more detail in the Form 10-Q, the Company had various loans outstanding to the plaintiffs. At the time of the filing of the complaint, such loans totaled $25.6 million. The borrowers' subsequently defaulted on the loans, and as a result the Company has liquidated certain deposit accounts and a letter of credit which served as partial collateral for the loans. The $2.3 million proceeds of the liquidation of the deposit accounts and letter of credit were applied as principal reductions on the loans reducing the outstanding aggregate balance to $23.3 million. In addition, based on recently completed reappraisals of the underlying real estate collateral securing the loans, reflecting an aggregate current appraised value of $12.8 million, the Company has charged off $10.5 million of the loans leaving an outstanding aggregate principal balance of $12.8 million. This charge-off reflects the assumption that the loans are solely collateral dependant and does not take into

account the potential recovery of additional amounts from the borrowers and guarantors. The remaining outstanding aggregate principal balance of the loans is past due and on non-accrual status, and will thus increase the Company's asset quality ratios relating to past due loans and leases, nonperforming loans and leases and nonperforming assets for the current quarter.

Net Charge-offs and Allowance for Loan and Lease Losses

Prior to the May 1, 2009 filing of the above-referenced lawsuit, payments on the subject loans had been made in a timely manner and the Company had expected the loans to continue to perform. Accordingly, the Company's previous guidance, which included guidance that net charge-offs for 2009 would equal approximately 70 basis points of total loans and leases, did not include the $10.5 million pre-tax charge-off related to these loans. The Company believes that its prospects for net charge-offs for 2009 have not materially changed other than the addition of the $10.5 million second quarter charge-off related to these loans.

The Company expects its allowance for loan and lease losses will increase in the current quarter from the 1.86% of total loans and leases at March 31, 2009. While the amount of such increase could be affected by a number of factors, based on current information, management estimates that this allowance ratio may increase by approximately 10 to 20 basis points at June 30, 2009.

Investment Securities Portfolio

In its regular quarterly conference call on April 14, 2009, the Company restated that it will manage its investment securities portfolio with a view to maximizing long-term total returns, buying securities when it believes it is advantageous to buy and selling securities when it believes it is beneficial to sell. In that call, the Company noted that it was a seller of investment securities in the first quarter of 2009 because of recent increases in market prices of certain securities and the Company's evolving assumptions regarding interest rate risk in light of recent developments in government monetary and fiscal policy. The Company also reported in that conference call that it expected gains on sales of securities in the second quarter of 2009 to offset all or a substantial portion of the cost of the then proposed FDIC special assessment.

Based on the Company's continued evaluation of interest rate risk, including the potential effects of significant United States government monetary and fiscal policy actions in recent months, the Company has continued to be a seller of investment securities and reduce the size of its investment securities portfolio in the first two months of the second quarter of 2009. From April 1, 2009 through May 29, 2009, the Company sold investment securities with a cost basis of approximately $167 million resulting in net pre-tax gains of approximately $14.5 million. The Company

will continue to manage its investment securities portfolio with a view to maximizing its return to the Company while managing the portfolio's credit risk and interest rate risk.

Net Interest Income and Net Interest Margin

The Company has a long-standing goal of achieving record net interest income in each quarter through a combination of growth in earning assets and maintaining a favorable net interest margin. The reduction in the Company's earning assets resulting from the recent sales of investment securities may keep the Company from reaching this goal in the current quarter and thereafter until sufficient growth in earning assets is achieved. However, the recent changes in the investment securities portfolio are not expected to keep the Company from achieving its guidance for net interest margin. In recent conference calls, the Company stated that it expects to achieve net interest margin in each quarter of 2009 at a level approximately equal to or slightly above the 4.52% level achieved in the fourth quarter of 2008. In the most recent quarterly conference call on April 14, 2009, the Company noted that the 4.73% net interest margin achieved in the first quarter of 2009 was not affected by significant unusual items and was a reasonable starting point for projecting net interest margin for the coming quarters. The Company believes that its prior guidance is still appropriate.

Special FDIC Assessment

As expected, on May 22, 2009 the Federal Deposit Insurance Corporation approved a final rule establishing a special assessment on all insured depository institutions. The Company estimates that its pre-tax cost of the special assessment will be approximately $1.3 million. The actual amount of the special assessment will be based on financial data as of June 30, 2009 and accrued as an expense in the second quarter.

Summary

The Company estimates that in the current quarter the increased costs from its higher than expected provision for loan and lease losses and the FDIC special assessment will be largely offset by the increased income from gains on sales of investment securities. As a result, the Company believes that its prior guidance that the Company will generate a good level of net income, or even a record level of net income, in each quarter of 2009 is still appropriate.
