EXHIBIT 99.1 Contacts: Kermit K. Houser Marshall J. Alexander President and CEO Executive VP and CFO (541)882-3444 X7133 (541)882-3444 X7120 News Release ================================================================================ KLAMATH FIRST TO SELL SEVEN BRANCHES TO THE BANK OF EASTERN OREGON KLAMATH FALLS, OREGON - September 10, 2003 - Klamath First Bancorp, Inc. (Nasdaq: KFBI) announced today that Klamath First Federal had agreed to sell seven branches located in northeastern Oregon to the Bank of Eastern Oregon. The branches that will be sold are located in the towns of Burns, Condon, Fossil, Heppner, John Day, Prairie City and Moro. The sale includes deposit accounts of approximately $66 million, which will double the size of the Bank of Eastern Oregon's six branches, and its $78 million in total assets. The fixed assets and branch locations will also be included in the sale; however, loans will not be included. It is anticipated that the Bank of Eastern Oregon will offer employment to all current branch employees. Kermit K. Houser, President and Chief Executive Officer commented, "As part of our strategic plan management and the Board of Directors have looked at the possibility of branch sales, closures and consolidations in an effort to improve Klamath First's operating efficiency over the past year but did not have any specific areas or branches targeted. With the recent announcement of our proposed merger with Sterling Financial Corporation (Nasdaq: STSA), several community banks indicated an interest in many of our rural branch locations. Klamath First determined that Bank of Eastern Oregon was the best candidate to acquire its branches since Bank of Eastern Oregon shared Klamath First Federal's commitment to customers and employees. In addition, a sale at this time would ensure that the Klamath First customers and employees at these branches experience only one organizational change rather than two. We do not anticipate any further sales or closures of branches prior to the Sterling merger," added Mr. Houser. "The Bank of Eastern Oregon is pleased to offer customers and employees of these branches the opportunity to join our great team. We were established in 1945 to meet the financial needs of rural communities in eastern Oregon, and these branch purchases will allow us to continue that tradition in markets and with customers we are very familiar with," stated George Koffler, President and Chief Executive Officer of the Bank of Eastern Oregon. Bank of Eastern Oregon currently intends to partially finance the proposed branch acquisition through the issuance of $2 million of Trust Preferred Securities. As previously announced, Klamath is party to a merger agreement pursuant to which Klamath will merge into Sterling Financial Corporation. Sterling was apprised of and concurred in the sale of these seven branches. The branch sale is expected to close in December subject to regulatory approval. About Klamath First Bancorp, Inc.
