The Private Securities Litigation Report Act of 1995 provides a "safe harbor" for certain forward-looking statements. This presentation contains forward-looking statements with

respect to the Corporation's financial condition, results of operations, plans, objectives, future performance or business. These forward-looking statements are subject to certain risks

and uncertainties, including those identified below, which could cause future results to differ materially from historical results or those anticipated.

The words "believe," "expect," "anticipate," "intend," "estimate," "goals,” "would," "could," "should" and other expressions which indicate future events and trends identify forward-

looking statements. We caution readers not to place undue reliance on these forward-looking statements, which is based only on information known to the Corporation, speak only as

of their dates, and if no date is provided, then such statements speak only as of today. There are a number of important factors that could cause future results to differ materially from

historical results or those anticipated, including, but not limited to: the credit risks of lending activities, including changes in the level and trend of loan delinquencies and write-offs and

changes in our allowance for loan losses and provision for loan losses that may be impacted by deterioration in the housing and commercial real estate markets; changes in general

economic conditions, either nationally or in our market areas; changes in the levels of general interest rates, and the relative differences between short and long term interest rates,

deposit interest rates, our net interest margin and funding sources; fluctuations in the demand for loans, the number of unsold homes, land and other properties and fluctuations in real

estate values in our market areas; secondary market conditions for loans and our ability to sell loans in the secondary market; results of examinations of us by the Board of Governors

of the Federal Reserve System (the “Federal Reserve Board”) and of our bank subsidiaries by the Federal Deposit Insurance Corporation (the “FDIC”), the Washington State

Department of Financial Institutions, Division of Banks (the “Washington DFI”) or other regulatory authorities, including the possibility that any such regulatory authority may, among

other things, institute a formal or informal enforcement action against us or our bank subsidiaries which could require us to increase our reserve for loan losses, write-down assets,

change our regulatory capital position or affect our ability to borrow funds or maintain or increase deposits, which could adversely affect our liquidity and earnings; the requirements

and restrictions that have been imposed upon Banner Corporation and Banner Bank under the memoranda of understanding with the Federal Reserve Bank of San Francisco (in the

case of Banner Corporation) and the FDIC and the Washington DFI (in the case of Banner Bank) and the possibility that Banner Corporation and Banner Bank will be unable to fully

comply with the memoranda of understanding, which could result in the imposition of additional requirements or restrictions; legislative or regulatory changes that adversely affect our

business including changes in regulatory policies and principles, or the interpretation of regulatory capital or other rules; our ability to attract and retain deposits; further increases in

premiums for deposit insurance; our ability to control operating costs and expenses; the use of estimates in determining fair value of certain of our assets, which estimates may prove

to be incorrect and result in significant declines in valuation; staffing fluctuations in response to product demand or the implementation of corporate strategies that affect our workforce

and potential associated charges; the failure or security breach of computer systems on which we depend; our ability to retain key members of our senior management team; costs

and effects of litigation, including settlements and judgments; our ability to implement our business strategies; our ability to successfully integrate any assets, liabilities, customers,

systems, and management personnel we may acquire and our ability to realize related revenue synergies and cost savings within expected time frames and any goodwill charges

related thereto; increased competitive pressures among financial services companies; changes in consumer spending, borrowing and savings habits; the availability of resources to

address changes in laws, rules, or regulations or to respond to regulatory actions; our ability to pay dividends on our common and preferred stock and interest or principal payments on

our junior subordinated debentures; adverse changes in the securities markets; inability of key third-party providers to perform their obligations to us; changes in accounting policies

and practices, as may be adopted by the financial institution regulatory agencies or the Financial Accounting Standards Board, including additional guidance and interpretation on

accounting issues and details of the implementation of new accounting methods; changes to the regulatory capital treatment of our Trust Preferred Securities; other economic,

competitive, governmental, regulatory, and technological factors affecting our operations, pricing, products and services; future legislative or regulatory changes in the United States

Department of Treasury Troubled Asset Relief Program (“TARP”) Capital Purchase Program and the other risks described elsewhere in the preliminary prospectus supplement, the

accompanying prospectus and the documents incorporated therein by reference.

The Corporation does not undertake any obligation to update any forward-looking statement to reflect circumstances or events that occur after the date on which the forward-looking

statement is made.

Use of Non-GAAP Financial Measures

Tangible equity, tangible common equity and tangible common equity to tangible assets are non-

GAAP financial measures. We calculate tangible equity by excluding the balance of goodwill and other

intangible

assets

from

shareholders’

equity.

calculate

tangible

common

equity

excluding

preferred equity from tangible equity. We calculate tangible assets by excluding the balance of

goodwill and other intangible assets from total assets. We believe that this is consistent with the

treatment by our bank regulatory agencies, which exclude goodwill and other intangible assets from

the calculation of risk-based capital ratios. Accordingly, management believes that these non-GAAP

financial measures provide information to investors that is useful in understanding the basis of our risk-

based

capital

ratios.

addition,

excluding

preferred

equity

(the

level

which

may

vary

from

company to company), it allows investors to more easily compare our capital adequacy to other

companies in the industry who also use this measure. We calculate normalized pre-tax, pre-provision

earnings by adding provision for loan losses to income before income taxes and exclude net change in

valuation of financial instruments carried at fair value, other-than-temporary impairment losses and

goodwill write-off. Management believes normalized pre-tax, pre-provision earnings is useful in

assessing the Company's core performance and trends, particularly during times of economic stress.

These non-GAAP financial measures are supplemental and are not a substitute for any analysis based

on GAAP financial measures. Because not all companies use the same calculations of tangible

common equity, tangible assets and normalized pre-tax, pre-provision earnings, these presentations

may not be comparable to other similarly titled measures as calculated by other companies.

Reconciliations of the non-GAAP financial measures are provided in Appendix D and in the “Summary
