(“RML” ) by Northrim Bank. All statements, other than statements of historical fact, regarding the financial position, business strategy and respective management’s plans and objectives for future operations of each of Northrim and RML are forward-looking statements. Readers should not place undue reliance on forward-looking statements, which reflect management’s views only as of the date hereof. When used in this presentation, the words “anticipate,” “believe,” “estimate,” “expect,” and “intend” and words or phrases of similar meaning, as they relate to Northrim, Northrim management, RML, or RML management are intended to help identify forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Although we believe that management’s respective expectations as reflected in forward-looking statements are reasonable, we cannot assure readers that those expectations will prove to be correct. Forward-looking statements are subject to various risks and uncertainties that may cause actual results to differ materially and adversely from expectations as indicated in the forward-looking statements. These risks and uncertainties include: expected cost savings, synergies and other financial benefits from the proposed transaction might not be realized within the expected time frames and costs or difficulties relating to integration matters might be greater than expected; the requisite regulatory approvals for the proposed transaction might not be obtained; and the ability of Northrim and RML to execute their respective business plans (including the acquisition of RML by Northrim Bank). Further, actual results may be affected by the ability to compete on price and other factors with other financial institutions; customer acceptance of new products and services; the regulatory environment in which we operate; and general trends in the local, regional and national banking industry and economy as those factors relate to the cost of funds and return on assets. In addition, there are risks inherent in the banking industry relating to collectability of loans and changes in interest rates. Many of these risks, as well as other risks that may have a material adverse impact on our operations and business, are identified in other filings of Northrim made with the Securities and Exchange Commission. However, you should be aware that these factors are not an exhaustive list, and you should not assume these are the only factors that may cause our actual results to differ from our expectations. These forward-looking statements are made only as of the date of this presentation, and neither Northrim nor RML undertakes an obligation to release revisions to these forward-looking statements to reflect events or conditions after the date of this presentation.
