Forward-looking Statements This presentation includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, which are intended to be covered by the “Safe-Harbor” provisions of the Private Securities Litigation Reform Act of 1995. These statements are necessarily subject to risk and uncertainty and actual results could differ materially due to various risk factors, including those set forth from time to time in our filings with the SEC. You should not place undue reliance on forward-looking statements and we undertake no obligation to update any such statements. Forward-looking statements include statements that expressly or implicitly predict future results, performance or event. Statements other than statements of historical fact are forward-looking statements, which can be identified by use of words such as “anticipates,” “expects,” “believes,” “estimates,” and “intends,” and words or phrases of similar meaning. In this presentation we make forward-looking statements about size and growth potential from the merger with Sterling Financial Corporation; organic growth; net interest margin opportunities; dividends, share repurchases and capital management; opportunities for future acquisitions; loan portfolio diversification; store divestiture in connection with the Sterling merger; the mitigating effect of FDIC loss sharing agreements on the covered loan portfolio; valuations of, and the potential accelerated redemption of, junior subordinated debentures and our current intent to not redeem those securities; costs of interest bearing deposits and management’s pricing strategy; systems conversions in connection with the Sterling merger; and the Sterling merger integration. Specific risks that could cause results to differ from the forward-looking statements are set forth in our filings with the SEC and include, without limitation: changes in the discounted cash flow model used to determine the fair value of subordinated debentures; prolonged low interest rate environment; unanticipated weakness in loan demand or loan pricing; deterioration in the economy; material reductions in revenue or material increases in expenses; lack of strategic growth opportunities or our failure to execute on those opportunities; our inability to effectively manage problem credits; certain loan assets becoming ineligible for loss sharing; unanticipated increases in the cost of deposits; the consequences of a phase-out of junior subordinated debentures from Tier 1 capital; our ability to achieve the synergies and earnings accretion contemplated by the Sterling merger; our ability to promptly and effectively integrate the businesses of Sterling and Umpqua; the diversion of management time on issues related to merger integration; changes in laws or regulations; and changes in general economic conditions. 2

Basel III Considerations > Under the final Basel III rules, three primary changes will take place: 1. Capital from TRUPs shifts from Tier 1 to Tier 2 (75% in 2015, 100% in 2016 and beyond) 2. Sterling net operating loss DTA picked up and will be completely excluded from Tier 1 (currently partially included in Tier 1) 3. Increase in risk-weighted assets (RWA), expected to decrease those capital ratios which use RWA by 40-50 bps Excess capital on a pro forma Basel III basis expected to be ~$150 million by early 2015 > Plan to continue to leverage through dividends, share repurchases and acquisitions / organic growth 13
