This communication contains “forward-looking statements” that are subject to risks and uncertainties. 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 BanCorp, Inc. (“Northrim”) and Alaska Pacific Bancshares, Inc. (“Alaska Pacific”) 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 communication, the words “anticipate,” “believe,” “estimate,” “expect,” and “intend” and words or phrases of similar meaning, as they relate to Northrim, Northrim’s management, Alaska Pacific, or Alaska Pacific’s 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 merger might not be realized within the expected time frames and costs or difficulties relating to integration matters might be greater than expected; the requisite shareholder and regulatory approvals for the proposed merger might not be obtained; and the ability of Northrim and Alaska Pacific to execute their respective business plans (including the proposed merger). 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 collectibility 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 and Alaska Pacific made with the SEC. 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 current report, and neither Northrim nor Alaska Pacific undertakes an obligation to release revisions to these forward-looking statements to reflect events or conditions after the date of this current communication.

This presentation may contain “forward-looking statements” as that term is defined for purposes of Section 21D of the Securities and Exchange Act.  These statements are, in effect, management’s attempt to predict future events, and thus are subject to various risks and uncertainties. Readers should not place undue reliance on forward-looking statements, which reflect management’s views only as of the date hereof. All statements, other than statements of historical fact, regarding our financial position, business strategy and management’s plans and objectives for future operations are forward-looking statements. 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, its management, or the proposed merger with Alaska Pacific Bancshares (“Alaska Pacific”) are intended to help identify forward-looking statements. Although we believe that management’s expectations as reflected in forward-looking statements are reasonable, we cannot assure readers that those expectations will prove to be correct. Our actual results may differ materially and adversely from our expectations as indicated in the forward-looking statements. These risks and uncertainties include our ability to maintain strong asset quality and to maintain or expand our market share or net interest margins, to implement our marketing and growth strategies, expected cost savings, synergies and other financial benefits from the proposed merger might not be realized within the expected time frames and costs or difficulties relating to integration matters might be greater than expected; the requisite shareholder and regulatory approvals for the proposed merger might not be obtained; and the ability of Northrim and Alaska Pacific to execute their respective business plans (including the proposed merger). Further, actual results may be affected by our 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 our 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 the “Risk Factors” section of our Annual Report on Form 10-K for the fiscal year ended December 31, 2012, and from time to time are disclosed in our other filings with the SEC. 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.
