                                               News Release

Walla Walla, WA - December 12, 2006 - Banner Corporation (Nasdaq: BANR), the parent company of Banner Bank, today announced the signing of a definitive merger agreement with F&M Bank, Spokane, Washington, in a stock and cash transaction valued at approximately $98.8 million. In connection with the transaction, F&M Bank will merge into Banner Bank. The merger will significantly expand Banner's presence in the Spokane, Washington area, the fourth largest metropolitan market in the Pacific Northwest. A conference call and investor presentation regarding the merger will be held today at 10 am PST.

Founded in 1906, F&M Bank is a state-chartered commercial community bank with $406 million in assets, $354 million in loans, $339 million in deposits and shareholders' equity of $39 million at September 30, 2006. With 14 branches in and around the Spokane area, the Bank specializes in meeting the financial needs of individuals, small and mid-sized businesses, government bodies and other legal entities.

"The officers, employees and board members of F&M Bank have created a dynamic and expanding community bank with a reputation for quality service in its market area," said D. Michael Jones, President and Chief Executive Officer of Banner Corporation. "Partnering with F&M Bank expands and strengthens our presence in the important Spokane market. The Spokane area has experienced strong population and job growth over the last several years along with improving median household income. The merger provides us a branch distribution network complementary to our own and it allows us to serve our growing customer base with a full range of products and an experienced staff in convenient locations. We believe that a combination of F&M Bank and Banner Bank will be a positive step for each bank's shareholders, customers and employees."

"Banner practices the same philosophy of providing outstanding customer service with competitive products and quality employees that has made F&M Bank so successful. Our "Warm Hearted Team" is pleased to be joining Banner," said John Wagner, President of F&M Bank. "We look forward to offering additional deposit products, larger lending limits, improved technology and operating efficiencies, all while retaining our focus on customer service and local decision making. Partnering with Banner Bank provides us with the resources for further growth and diversification in the Spokane market and allows immediate regional banking access for our customers through Banner's expanded Northwest presence."

"Given F&M Bank's experienced staff, low-cost deposit structure and strong customer base in a market where we are expanding, we anticipate very positive results from the merger," said Jones. "We expect this acquisition to be essentially neutral to our earnings per share for the second half of 2007 and accretive to our full-year 2008 earnings per share. Banner Bank currently has two branches and two lending offices in the Spokane area. When the prospect of this transaction arose, we viewed it as an excellent opportunity to fully serve the fourth largest metropolitan area in the Pacific Northwest which has important ties to our other three markets of emphasis, the Puget Sound region, greater Portland and greater Boise."

According to the terms of the definitive agreement and assuming all outstanding F&M Bank options are exercised, F&M Bank shareholders will receive 0.8500 shares of Banner Corporation common stock and $9.30 in cash for each F&M Bank share, plus a pro-ration of the annual cash dividend through the date of closing. The acquisition, which has been approved by the Boards of Directors of both companies, is subject to, among other contingencies, approval by regulators and F&M Bank shareholders. The transaction is expected to close during the second quarter of 2007.
