Banner Corporation Signs Definitive Agreement to Acquire NCW Community Bank of Wenatchee, Washington.

WALLA WALLA, Wash. -- Banner Corporation (NASDAQ:BANR), the parent company of Banner Bank, today announced the signing of a definitive merger agreement with NCW Community Bank, Wenatchee, Washington, in a stock and cash transaction valued at approximately $18.5 million. In connection with the transaction, NCW Community Bank will merge into Banner Bank. The merger will significantly expand Banner's presence in the North Central Washington area.

Founded in 1999, NCW Community Bank is a state-chartered commercial community bank with $90 million in assets, $81 million in loans, $78 million in deposits and shareholders' equity of $9 million at March 31, 2007. With one branch in Wenatchee and one under construction in East Wenatchee, the Bank specializes in meeting the financial needs of individuals and small and mid-sized businesses in its local market.

"The officers, employees and board members of NCW Community Bank have created a vibrant community bank with a reputation for high quality service and strong community involvement in its market area," said D. Michael Jones, President and Chief Executive Officer of Banner Corporation. "Partnering with NCW Community Bank expands and strengthens our presence in North Central Washington. The Wenatchee area has experienced robust economic growth over the last several years with strong population growth and increasing median household income. The merger provides us with the opportunity to consolidate locations while strengthening our market penetration and allows us to serve a larger customer base with a full range of products and additional experienced staff. Combined, NCW Community Bank and Banner Bank will hold the number two market share position in the greater Wenatchee area. We believe that a combination of NCW Community Bank and Banner Bank will be a positive step for each bank's customers, employees and shareholders."

"We are very pleased to be joining the Banner team, which brings financial strength, additional management experience and new technological capabilities to our organization," stated Melvin J. Hansen, President and Chief Executive Officer of NCW Community Bank. "Banner practices the same philosophy of providing outstanding customer service with competitive products and quality employees that has made NCW Community Bank so successful. We look forward to offering a broader range of services to our customers, increased lending limits, and expanded branch and ATM networks. Partnering with Banner Bank provides us with the resources for further growth and diversification in the North Central Washington market and allows immediate regional banking access for our customers through Banner's expanded Northwest presence. Both banks have histories of active community involvement and I am confident our employees and customers will feel very comfortable in joining with Banner."

"Given NCW Community Bank's experienced staff, low-cost deposit structure and strong customer base, we anticipate very positive results from the merger," said Jones. "We expect this acquisition to modestly add to Banner's net income and earnings per share during the first year following acquisition and to provide further earnings accretion in subsequent years. Banner Bank currently has two branches in the Wenatchee area. We view this transaction as an excellent opportunity to serve more fully an important economic region of the state."

Subject to the terms of the definitive agreement and assuming all outstanding NCW Community Bank options are exercised, NCW Community Bank shareholders will receive 0.7425 shares of Banner Corporation common stock and $14.19 in cash for each NCW Community Bank share. The acquisition, which has been approved by the Boards of Directors of both companies, is subject to, among other contingencies, approval by regulators and NCW Community Bank shareholders. The transaction is expected to close during the fourth quarter of 2007.
