Forward-Looking Statements

When used in this communication and in other documents filed with or furnished to the Securities and Exchange Commission (the “SEC”), in press releases or other public stockholder communications, or in oral statements made with the approval of an authorized executive officer, the words or phrases “may,” “believe,” “will,” “will likely result,” “are expected to,” “will continue,” “is anticipated,” “estimate,” “project,” “plans,” “potential,” or similar expressions are intended to identify “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.  Investors and security holders are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date such statements are made.  These statements may relate to future financial performance, strategic plans or objectives, revenues or earnings projections, or other financial information.  By their nature, these statements are subject to numerous uncertainties that could cause actual results to differ materially from those anticipated in the statements.  Statements about the expected timing, completion and effects of the proposed merger and all other statements in this communication other than historical facts constitute forward-looking statements.

In addition to factors disclosed in Banner’s SEC reports, important factors that could cause actual results to differ materially from the results anticipated or projected include, but are not limited to, the following:  expected revenues, cost savings, synergies and other benefits from the proposed merger of Banner and Skagit might not be realized within the expected time frames or at all and costs or difficulties relating to integration matters, including but not limited to customer and employee retention, might be greater than expected; the requisite regulatory approvals for the proposed merger of Banner and Skagit may be delayed or may not be obtained (or may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed merger); the requisite approval of Skagit shareholders may be delayed or may not be obtained, the other closing conditions to the merger may be delayed or may not be obtained, or the merger agreement may be terminated; business disruption may occur following or in connection with the proposed merger of Banner and Skagit; Banner’s or Skagit’s businesses may experience disruptions due to transaction-related uncertainty or other factors making it more difficult to maintain relationships with employees, customers, other business partners or governmental entities; the possibility that the proposed merger is more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of managements’ attention from ongoing business operations and opportunities as a result of the proposed merger or otherwise; the credit risks of lending activities, including changes in the level and trend of loan delinquencies and write-offs and changes in estimates of the adequacy of the allowance for loan losses and provisions for loan losses that may be impacted by deterioration in the housing and commercial real estate markets and may lead to increased losses and non-performing assets, and may result in the allowance for loan losses not being adequate to cover actual losses and require a material increase in reserves; results of examinations by regulatory authorities, including the possibility that any such regulatory authority may, among other things, require the writing down of assets or increases in the allowance for loan losses; the ability to manage loan delinquency rates; competitive pressures among financial services companies; changes in consumer spending or borrowing and spending habits; interest rate movements generally and the relative differences
