Notes to Consolidated Financial Statements

1. Basis of Presentation:

The foregoing unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally
accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission. Accordingly, these financial statements do
not include all of the disclosures required by accounting principles generally accepted in the United States of America for complete financial statements. These unaudited interim consolidated financial statements should be read in conjunction with
the audited consolidated financial statements as disclosed in the annual report on Form 10-K for the year ended December 31, 2009. In the opinion of management, the unaudited interim consolidated financial statements furnished herein include
all adjustments, all of which are of a normal recurring nature, necessary for a fair statement of the results for the interim periods presented.

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America
requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities known to exist as of the date the financial statements are published, and the reported amounts
of revenues and expenses during the reporting period. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of Sterling Financial Corporations (Sterlings) consolidated financial
statements; accordingly, it is possible that the actual results could differ from these estimates and assumptions, which could have a material effect on the reported amounts of Sterlings consolidated financial position and results of
operations. These financial statements have been prepared under the assumption that the entity is a going concern, an assumption for which Sterlings Independent Public Accountants expressed substantial doubt in their opinion relating to the
December 31, 2009 consolidated financial statements.

In addition to other established accounting policies, the following
is a discussion of recent accounting pronouncements:

In May 2009, the FASB issued guidance on subsequent events that
standardizes accounting for and disclosures of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. In February 2010, the FASB amended its guidance on subsequent events. As a public
reporting company, Sterling is required to evaluate subsequent events through the date its financial statements are issued. The adoption of these rules did not have a material impact on Sterlings consolidated financial statements.

In June 2009, the FASB issued standards on accounting for transfers of financial assets, removing the concept of qualifying
special-purpose entities as an accounting criteria that had provided an exception to consolidation, and provided additional guidance on requirements for consolidation. This guidance became effective for Sterling on January 1, 2010, and did not
have a material impact on its consolidated financial statements.

In January 2010, the FASB issued guidance on considerations
related to implementation of fair value measurement disclosures. This update to the codification specifically addresses: 1) transfers between levels 1, 2 and 3 of the fair value hierarchy; 2) level of disaggregation of derivative contracts for fair
value measurement disclosures; and 3) disclosures about fair value measurement inputs and valuation techniques. This guidance became effective for Sterling on March 31, 2010, and did not have a material impact on its consolidated financial
statements.

The amortized cost and fair value of available-for-sale and held-to-maturity debt securities as of
March 31, 2010, are listed below according to contractual maturity date. Expected or actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment
penalties.

Management evaluates investment securities for other
than temporary declines in fair value on a quarterly basis. If the fair value of investment securities falls below their amortized cost and the decline is deemed to be other than temporary, the securities will be written down to current market
value, resulting in a loss. There were no investment securities that management identified to be other than-temporarily impaired for the three months ended March 31, 2010, because the decline in fair value of certain classes of securities was
attributable to temporary disruptions of credit markets and the related impact on securities within those classes, not deteriorating credit quality of specific securities. Sterling holds positions in classes of securities negatively impacted by
temporary credit market disruptions, including a single-issuer trust preferred security, and private label collateralized mortgage obligations. As of March 31, 2010, the trust preferred security is rated A1 by Moodys and has an
amortized cost of $24.7 million compared to a $20.9 million market value, or an unrealized loss of $3.8 million. As of March 31, 2010, the private label collateralized mortgage obligations had an aggregate amortized cost of $139.3 million
compared to a $135.0 million market value, or an unrealized loss of $4.2 million. All private label collateralized mortgage obligations are internally monitored monthly and independently stress-tested quarterly for both credit quality and collateral
strength, and are investment grade according to at least one rating agency. As of March 31, 2010, S&P had a rating of below investment grade on two of these securities, while Moodys maintained its investment grade rating on the
same securities. At March 31, 2010, these two private label collateralized mortgage obligations had an amortized cost of $46.4 million and a market value of $44.0 million. The vintage, or years of issuance, for these nonagency MBS

ranges from 2003 to 2005. As of March 31, 2010, Sterling expects the return of all principal and interest on all securities within the portfolios pursuant to the contractual terms, has
the ability and intent to hold these investments, has no intent to sell securities that are deemed to have a market value impairment, and Sterling does not believe it is more likely than not that it would be required to sell these investments before
a recovery in market price occurs, or until maturity. Realized losses could occur in future periods due to a change in managements intent to hold the investments to recovery, a change in managements assessment of credit risk, or a change
in regulatory or accounting requirements.

The increase in the provision is in response to the level of classified loans and an increase in the level
of charge-offs, with higher loss rates related to the decline in collateral values, particularly in the construction, commercial real estate and residential real estate portfolios. Classified assets include performing substandard loans,
nonperforming loans and OREO. Nonperforming loans and OREO comprise nonperforming assets, for which the following summarizes as of the dates indicated:

Cumulatively, Sterling has written down its nonperforming assets by $626.3 million as of March 31,
2010, compared with write-downs of $579.7 million as of December 31, 2009 and $244.0 million as of March 31, 2009, primarily reflecting lower real estate appraisal values. Additionally, Sterling has established specific reserves of $19.0
million against its nonperforming loans for valuation changes between appraisals, and $12.0 million for its OREO properties.

At the applicable foreclosure date, other real estate owned is recorded at the fair value of
the real estate, less the costs to sell the real estate. The carrying value of OREO is regularly evaluated and, if necessary, an allowance is established to reduce the carrying value to net realizable value. As of March 31, 2010, the allowance
for losses on OREO totaled $12.0 million. Changes in this allowance are as follows for the periods presented:

Sterling has raised capital through the formation of
trust subsidiaries (Capital Trusts), which issue capital securities (Trust Preferred Securities) to investors. The Capital Trusts are business trusts in which Sterling owns all of the common equity. The proceeds from the sale
of the Trust Preferred Securities are used to purchase junior subordinated deferrable interest debentures (Junior Subordinated Debentures) issued by Sterling. Sterlings obligations under the Junior Subordinated Debentures and
related documents, taken together, constitute a full and unconditional guarantee by Sterling of the Capital Trusts obligations under the Trust Preferred Securities. The Trust Preferred Securities are treated as debt of Sterling. The Junior
Subordinated Debentures and related Trust Preferred Securities generally mature 30 years after issuance and are redeemable at the option of Sterling under certain conditions, including, with respect to certain of the Trust Preferred Securities,
payment of call premiums. During the third quarter of 2009, Sterling elected to defer regularly scheduled interest payments on these securities. Sterling is allowed to defer payments of interest on the junior subordinated notes for up to 20
consecutive quarterly periods without triggering an event of default.

Shareholders Equity:

At March 31, 2010, Sterling and its subsidiary Sterling Savings Bank were categorized under
regulatory guidelines as undercapitalized. As a result, Sterling is subject to various restrictions, including restrictions on asset growth, acquisitions, new activities and new branches. Sterling and Sterling Savings Bank are operating
under regulatory agreements; Sterling Savings Banks regulators have directed Sterling Savings Bank to increase its overall capital levels and, in particular, are requiring Sterling Savings Bank to increase its Tier 1 leverage ratio to 10.0%.
In April 2010, Sterling and Thomas H. Lee Partners, L.P. (THL) entered into a definitive agreement (the THL Agreement) pursuant to which THL would purchase a combination of preferred and common stock and warrants for an
aggregate purchase price of approximately $134.7 million. On May 3, 2010, Sterling announced that Sterling and THL intend to increase the size of the proposed investment in Sterling to $170 million, subject to the approval of the U.S. Department of
the Treasury (the Treasury). For further discussion, see Note 14.

On December 5, 2008, Sterling issued 303,000 shares of
preferred stock and a warrant for 6,437,677 shares of common stock to the Treasury for $303.0 million of Capital Purchase Program funds. During the third quarter of 2009, Sterling elected to defer the payment of dividends on this cumulative
preferred stock. Under the terms of the preferred stock, failure to pay dividends for six dividend periods, whether or not consecutive, would cause the authorized number of directors constituting Sterlings board of directors to be
automatically increased by two, and the holders of the preferred stock, together with the holders of any outstanding parity stock with like voting rights, would be entitled to elect the two additional members of Sterlings board of directors.
In April, Sterling entered into a definitive agreement with the Treasury providing for, among other things, the exchange of the 303,000 shares of preferred stock held by the Treasury through its Capital Purchase Program for 303,000 shares of a
newly-created Series C Fixed Rate Cumulative Mandatorily Convertible Preferred Stock (the Series C Stock) with a liquidation preference of $303.0 million. For further discussion, see Note 14.

The Codification requires a two-class method of computing earnings per share for entities that
have participating securities such as Sterlings unvested restricted shares. Application of the two-class method resulted in the materially equivalent earnings per share as the application of the treasury method, which is presented above.

The increase in non-interest expenses was mainly due
to an increase in Federal Deposit Insurance Corporation (FDIC) deposit insurance premiums, expenses related to increased credit resolution costs and OREO operations, and expenses associated with Sterlings recapitalization efforts.

8. Income Taxes:

Sterling uses an estimate of future earnings, and an evaluation of its loss carryback ability and tax planning strategies to determine
whether or not the benefit of its net deferred tax asset will be realized. Sterling has assessed whether it was more likely than not that it would realize the benefits of its deferred tax asset. Sterling determined that the negative evidence
associated with a projected three-year cumulative loss, the regulatory agreement in place between Sterling Savings Bank and the FDIC (the SSB Consent Agreement) and between Sterling and the Federal Reserve Bank of San Francisco (the
Reserve Bank Agreement), and continued credit deterioration in its loan portfolio outweighed the positive evidence. Therefore, a valuation allowance was established against its deferred tax asset, with the allowance totaling $303.0
million as of March 31, 2010, compared with $269.0 million as of December 31, 2009.

Subsequent to March 31,
2010, Sterlings Board of Directors adopted a shareholder rights plan designed to preserve substantial tax assets that include net operating losses, capital losses and certain built-in losses that could be utilized in certain circumstances to
offset taxable income and reduce its federal income tax liability. See Note 14.

11. Derivatives and Hedging:

As part of its mortgage banking activities, Sterling issues interest rate lock commitments to prospective borrowers on residential
mortgage loan applications. Pricing for the sale of these loans is fixed with various qualified investors under both non-binding (best-efforts) and binding (mandatory) delivery programs. For mandatory delivery programs,
Sterling hedges interest rate risk by entering into offsetting forward sale agreements on MBS with third parties. Risks inherent in mandatory delivery programs include the risk that if Sterling does not close the loans subject to interest rate lock
commitments, it is nevertheless obligated to deliver MBS to the counterparty under the forward sale agreement. Sterling could incur significant costs in acquiring replacement loans or MBS and such costs could have a material adverse effect on
mortgage banking operations in future periods.

Interest rate lock commitments and loan delivery commitments are off balance
sheet commitments that are considered to be derivatives. As of March 31, 2010, Sterling had $200.8 million of interest rate lock commitments, $96.6 million of warehouse loans held for sale that were not committed to investors, and held
offsetting forward sale agreements on MBS valued at $301.5 million. In addition, Sterling had mandatory delivery commitments to sell mortgage loans to investors valued at $42.5 million as of March 31, 2010. As of December 31, 2009,
Sterling had $110.0 million of interest rate lock commitments, $119.7 million of warehouse loans held for sale that were not committed to investors, and held offsetting forward sale agreements on MBS valued at $234.0 million. In addition,
Sterling had mandatory delivery commitments to sell mortgage loans to investors valued at $29.5 million as of December 31, 2009. As of March 31, 2010 and December 31, 2009, Sterling had entered into best efforts forward commitments to
sell $19.6 million and $51.6 million of mortgage loans, respectively.

In the normal course of business, Sterling enters into
interest rate swap transactions with loan customers. The interest rate risk on these swap transactions is managed by entering into offsetting interest rate swap agreements with various counterparties (broker-dealers or
dealers). The counterparty swap agreements include certain representations, warranties and covenants, which include terms that allow for an early termination in the event of default. Failure to maintain a well capitalized position is one
event that may be considered a default, and counterparties to the swap agreements could require an early termination settlement or an increase in the collateral to secure derivative instruments that are in net liability positions to
Sterling. The early termination provision of the swap agreements could result in Sterling reimbursing the counterparty and recording a charge equal to the current market value of the swap agreement if terminated. During the
three months ended March 31, 2010, no counterparties declared an early termination event. The aggregate fair value of all derivative instruments with credit risk related contingent features that are in a liability position on March 31,
2010 was $4.5 million for which Sterling had already posted collateral with a market value of $5.4 million. Both customer and dealer related interest rate derivatives are carried at fair value by Sterling.

12. Fair Value:

Fair value estimates are determined as of a specific date using quoted market prices, where available, or various assumptions and
estimates. As the assumptions underlying these estimates change, the fair value of the financial instruments will change. The use of assumptions and various valuation techniques, as well as the absence of secondary markets for certain financial
instruments, will likely reduce the comparability of fair value disclosures between financial institutions. Accordingly, the aggregate fair value amounts presented do not represent and should not be construed to represent the full underlying value
of Sterling.

Companies have the
option of carrying financial assets and liabilities at fair value, which can be implemented on all or individually selected financial instruments. The framework for defining and measuring fair value requires that one of three valuation methods be
used to determine fair market value: the market approach, the income approach or the cost approach. To increase consistency and comparability in fair value measurements and related disclosures, the standard also creates a fair value hierarchy to
prioritize the inputs to these valuation methods into the following three levels:



| |  |  | Level 1 inputs are a select class of observable inputs, based upon the quoted prices for identical instruments in active markets that are accessible
as of the measurement date, and are to be used whenever available.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 2 inputs are other types of observable inputs, such as quoted prices for similar instruments in active markets; quoted prices for identical or
similar instruments in markets that are inactive; or other inputs that are observable or can be derived from or supported by observable market data. Level 2 inputs are to be used whenever Level 1 inputs are not available.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3 inputs are significantly unobservable, reflecting the reporting entitys own assumptions regarding what market participants would
assume when pricing a financial instrument. Level 3 inputs are to be used only when Level 1 and Level 2 inputs are unavailable.

Level 2 derivatives represent mortgage banking interest rate lock and loan delivery
commitments, while level 3 derivatives represent interest rate swaps, with market values for these instruments being a function of the interest rate and term of the underlying loan. See Note 11 for a further discussion of these derivatives. Changes
in the fair value of available-for-sale securities are recorded on the balance sheet under accumulated-other-comprehensive income, while gains and losses from sales are recognized as income. The difference between the aggregate fair value and the
aggregate unpaid principal balance of loans held for sale that are carried at fair value were included in earnings as follows:

Assets and Liabilities Measured at Fair Value on a Non-recurring Basis.Sterling may be required, from time to time, to measure certain other financial assets at fair value on a non-recurring basis from application of lower of cost or market (LOCOM) accounting or write-downs of individual assets.

The loans disclosed above
represent the carrying value of impaired loans at period end. Mortgage servicing rights were written down mainly due to an acceleration of mortgage prepayments. Sterling carries its mortgage servicing rights at LOCOM, and as such, they are measured
at fair value on a non-recurring basis. OREO represents the carrying value after write-downs taken at foreclosure that were charged to the loan loss allowance, as well as specific reserves established subsequent to foreclosure due to updated
appraisals. Goodwill is presented at fair value, net of impairment charges.

The methods and assumptions used to estimate the fair value of
each class of financial instruments are as follows:

Cash and Cash Equivalents

The carrying value of cash and cash equivalents approximates fair value due to the relatively short-term nature of these instruments.

Investments and MBS

The fair value of investments and MBS has been valued using a matrix pricing technique based on quoted prices for similar instruments,
which Sterling validates with non-binding broker quotes, in depth collateral analysis and cash flow stress testing.

Sterling has elected to carry loans held for sale at fair value. The fair values are based on investor quotes in the
secondary market based upon the fair value of options and commitments to sell or issue mortgage loans. The fair value election was made to match changes in the value of these loans with the value of their economic hedges. Loan origination fees,
costs and servicing rights, which were previously deferred on these loans, are now recognized as part of the loan value at origination. As of March 31, 2010 and December 31, 2009, Sterling had $1.2 million and $1.3 million, respectively,
of loans held for sale that were being reported at the lower of amortized cost or market value.

Loans Receivable

The fair value of performing loans is estimated by discounting the cash flows using interest rates that consider the current credit and
interest rate risk inherent in the loans and current economic and lending conditions. The fair value of nonperforming loans is estimated by discounting managements current estimate of future cash flows using a rate estimated to be commensurate
with the risks involved. The fair value of nonperforming collateral dependent loans is estimated based upon the value of the underlying collateral. In addition, to reflect current market conditions, a liquidity discount has been applied against the
portfolio.

##### Table of Contents

Mortgage Servicing Rights

The fair value of mortgage servicing rights is estimated using a discounted cash flow methodology to arrive at the present value of future expected
earnings from the servicing of the loans. Model inputs include prepayment speeds, market interest rates, contractual interest rates on the loans being serviced, and the amount of other fee income generated over the servicing contract.

OREO

The fair value of OREO is
estimated using third party appraisals, subject to updates to reflect comparable market transactions, with appraisals ordered for as is or disposal value.

Deposits

The fair values of deposits
subject to immediate withdrawal such as interest and noninterest bearing checking, regular savings, and money market deposit accounts, are equal to the amounts payable on demand at the reporting date, net of a core deposit intangible. Fair values
for time deposits are estimated by discounting future cash flows using interest rates currently offered on time deposits with similar remaining maturities.

Borrowings

The carrying amounts of
short-term borrowings under repurchase agreements, federal funds purchased, short-term FHLB advances and other short-term borrowings approximate their fair values due to the relatively short period of time between the origination of the instruments
and the expected payment dates on the instruments. The fair value of advances under lines of credit approximates their carrying value because such advances bear variable rates of interest. The fair value of long-term FHLB advances and other
long-term borrowings is estimated using discounted cash flow analyses based on Sterlings current incremental borrowing rates for similar types of borrowing arrangements with similar remaining terms.

13. Going Concern:

These
financial statements have been prepared under the assumption that the entity is a going concern. As a result of the uncertainty regarding Sterlings ability to comply with the Reserve Bank Agreement and the SSB Consent Agreement,
Sterlings Independent Registered Public Accounting Firm added an explanatory paragraph in their audit opinion issued in connection with our December 31, 2009 consolidated financial statements, expressing substantial doubt regarding our
ability to continue as a going concern. Managements plans to address this uncertainty include the raising of capital, or the potential sale of Sterling or some or all of its assets. On April 29, 2010, Sterling entered into the THL
Agreement, which is subject to various conditions, including, among others, Sterling raising total capital of at least $720 million (inclusive of the THL Transaction), and a conversion of the Treasurys preferred stock at a discount to the face
value. There can be no assurance that any of these efforts will be successful, and if Sterling were to be unsuccessful, its ongoing viability would be in doubt.

14. Subsequent Events:

In April
2010, Sterlings previously announced consent solicitation relating to a discounted purchase offer for its outstanding Trust Preferred Securities expired. No amendments were made to applicable indentures, and Sterling is no longer seeking
approval for such amendments or to purchase its outstanding Trust Preferred Securities.

In April 2010, Sterlings Board of Directors
adopted a shareholder rights plan designed to preserve substantial tax assets that include net operating losses, capital losses and certain built-in losses that could be utilized in certain circumstances to offset taxable income and reduce its
federal income tax liability. Sterlings ability to use its tax attributes would be substantially limited if there were an ownership change as defined under Section 382 of the Internal Revenue Code and related Internal Revenue
Service pronouncements. In general, an ownership change

##### Table of Contents

would occur if Sterlings 5-percent shareholders, as defined under Section 382, collectively increase their ownership in Sterling by more than 50 percentage points over a
rolling three-year period. Five-percent shareholders do not include certain institutional holders, such as mutual fund companies, that hold Sterling equity securities on behalf of several individual mutual funds where no single fund owns 5 percent
or more of Sterling equity securities. As part of the plan, the Sterling Board of Directors declared a dividend of one preferred share purchase right for each outstanding share of its common stock. The preferred share purchase rights were
distributable to shareholders of record as of April 15, 2010, as well as to holders of common stock and Sterling securities convertible into common stock issued after that date, but would only be activated if triggered pursuant to the terms of
the plan. See Sterlings Current Report on Form 8-K, as filed with the SEC on April 15, 2010, for additional information regarding the shareholder rights plan.

In April 2010, Sterlings Board of Directors approved the merger of Golf Savings Bank with and into Sterling Savings Bank, subject to regulatory
approval.

On April 29, 2010, Sterling and THL entered into the THL Agreement pursuant to which it is expected that THL will purchase
shares of Sterlings common stock (the Common Stock) at a price of up to $0.20 per share and shares of a newly-created Series B Convertible Participating Voting Preferred Stock (the Series B Stock) at a price of $75.00
per share of Series B Stock, representing a pro forma ownership interest of 16.6% on an as-converted basis, for an aggregate purchase price of approximately $134.7 million. THL would also receive a warrant with a seven-year term to purchase
168,383,759 shares of Common Stock exercisable at a price of up to $0.22 per share, representing a total investment of 19.9% on an as-converted basis and assuming the exercise of these warrants (together with the purchase of the Common Stock and the
Series B Stock, the THL Transaction). A copy of the THL Agreement is attached hereto as Exhibit 10.1.

In connection with the THL
Transaction, on April 29, 2010, Sterling executed a definitive exchange agreement (the Treasury Exchange Agreement) with the U.S. Department of the Treasury (the Treasury) providing for (i) the exchange of the
303,000 shares of preferred stock held by the Treasury through its Capital Purchase Program for 303,000 shares of a newly-created Series C Fixed Rate Cumulative Mandatorily Convertible Preferred Stock (the Series C Stock) with a
liquidation preference of $303 million, (ii) the exchange of the Series C Stock at a discounted exchange value of $75.75 million into 378,750,000 shares of Common Stock at a conversion price of $0.20 per share prior to the closing of the THL
Transaction; and (iii) the amendment of the terms of the warrant currently held by Treasury to provide for an exercise price of $0.20 per share for a ten-year term following the THL Transaction. A copy of the Treasury Exchange Agreement is
attached hereto as Exhibit 10.2.

On May 3, 2010, Sterling announced that Sterling and THL intend to increase the size of the proposed
investment in Sterling to $170 million, subject to the approval of the Treasury under the terms of the Treasury Exchange Agreement. If approved, THL would purchase shares of Common Stock at a price of up to $0.20 per share and shares of
Series B Stock at $92.00 per share, each of which would be mandatorily convertible into 460 shares of Common Stock. THL would continue to receive a warrant with a seven-year term to purchase shares of Common Stock exercisable at a price of up
to $0.22 per share, representing a total investment of 24.9% on an as-converted basis and assuming the exercise of these warrants. If approved, the THL Agreement and the Treasury Exchange Agreement would be revised to reflect the increased size of
the investment and certain other related technical matters.

The THL Transaction and the Treasury Exchange Transaction are conditioned upon
each other and on other closing conditions, including Sterling raising a total of at least $720 million (inclusive of the THL investment), which would enable it to meet all of its regulatory capital requirements.

PART I  Financial Information (continued)

Item 2  Managements Discussion and Analysis of Financial Condition and Results of
Operations

STERLING FINANCIAL CORPORATION

March 31, 2010

This report contains forward-looking statements. For a discussion about such statements, including the risks and uncertainties inherent therein, see
Forward-Looking Statements. Managements Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the Consolidated Financial Statements and Notes presented elsewhere in this report
and in Sterlings 2009 annual report on Form 10-K.

General

Sterling Financial Corporation (Sterling) is a bank holding company, organized under the laws of Washington State in 1992. The principal
operating subsidiaries of Sterling are Sterling Savings Bank and Golf Savings Bank. Sterling Savings Bank, headquartered in Spokane, Washington, commenced operations in 1983 as a Washington State-chartered federally insured stock savings and loan
association, and in 2005 converted to a commercial bank. Sterling Savings Bank offers commercial banking products and services, mortgage lending, construction financing and investment products to individuals, small business, commercial organizations
and corporations. The main focus of Golf Savings Bank, a Washington State-chartered savings bank acquired by Sterling in July 2006, is the origination and sale of residential mortgage loans.

Sterlings dedication to personalized service and relationship banking has enabled it to grow both its retail deposit base and its lending portfolio
in the western United States. With $10.55 billion in total assets as of March 31, 2010, Sterling originates loans and attracts Federal Deposit Insurance Corporation (FDIC) insured and uninsured deposits from the general public
throughout its five state footprint through its two subsidiary banks, Sterling Savings Bank and Golf Savings Bank, and through its commercial real estate division INTERVEST-Mortgage Investment Company (INTERVEST). Sterling also markets
fixed income and equities, mutual funds, annuities and other financial products through wealth management representatives located throughout Sterlings financial service centers network.

Recent Developments

Sterling faces a
number of challenges resulting from operating losses, driven by credit quality issues, and currently is categorized as being undercapitalized pursuant to regulatory guidelines. Both Sterling and Sterling Savings Bank are currently operating under
regulatory agreements with the Federal Reserve Bank of San Francisco and the FDIC, respectively. Both agreements require, among other things, a return to a well capitalized status. As a result of the uncertainty regarding Sterlings
ability to comply with these agreements, Sterlings Independent Registered Public Accounting Firm added an explanatory paragraph in their audit opinion issued in connection with our December 31, 2009 consolidated financial statements,
expressing substantial doubt regarding our ability to continue as a going concern.

In April 2010, Sterlings Board of Directors approved
the merger of Golf Savings Bank with and into Sterling Savings Bank, subject to regulatory approval.

On April 29, 2010, Sterling and
Thomas H. Lee Partners, L.P. (THL) entered into a definitive investment agreement (the THL Agreement) pursuant to which it is expected that THL will purchase shares of Sterlings common stock (the Common
Stock) at a price of up to $0.20 per share and shares of a newly-created Series B Convertible Participating Voting Preferred Stock (the Series B Stock) at a price of $75.00 per share of Series B Stock, representing a pro forma
ownership interest of 16.6% on an as-converted basis, for an aggregate purchase price of approximately $134.7 million. THL would also receive a warrant with a seven-year term to purchase 168,383,759 shares of Common Stock exercisable at a price of
up to $0.22 per share, representing a total investment of 19.9% on an as-converted basis and assuming the exercise of these warrants (together with the purchase of the Common Stock and the Series B Stock, the THL Transaction). A copy of
the THL Agreement is attached hereto as Exhibit 10.1.

In connection with the THL Transaction, on April 29, 2010, Sterling executed a
definitive exchange agreement (the Treasury Exchange Agreement) with the U.S. Department of the Treasury (the Treasury) providing for (i) the

##### Table of Contents

exchange of the 303,000 shares of preferred stock held by the Treasury through its Capital Purchase Program for 303,000 shares of a newly-created Series C Fixed Rate Cumulative Mandatorily
Convertible Preferred Stock (the Series C Stock) with a liquidation preference of $303 million, (ii) the exchange of the Series C Stock at a discounted exchange value of $75.75 million into 378,750,000 shares of Common Stock at a
conversion price of $0.20 per share prior to the closing of the THL Transaction; and (iii) the amendment of the terms of the warrant currently held by Treasury to provide for an exercise price of $0.20 per share for a ten-year term following
the THL Transaction (the Treasury Exchange Transaction). See Sterlings Current Report on Form 8-K, as filed with the SEC on April 27, 2010, for additional information regarding the THL Transaction and the exchange with
Treasury. A copy of the Treasury Exchange Agreement is attached hereto as Exhibit 10.2.

On May 3, 2010, Sterling announced that Sterling and
THL intend to increase the size of the proposed investment in Sterling to $170 million, subject to the approval of the Treasury under the terms of the Treasury Exchange Agreement. If approved, THL would purchase shares of Common Stock at a price of
up to $0.20 per share and shares of Series B Stock at $92.00 per share, each of which would be mandatorily convertible into 460 shares of Common Stock. THL would continue to receive a warrant with a seven-year term to purchase shares of Common Stock
exercisable at a price of up to $0.22 per share, representing a total investment of 24.9% on an as-converted basis and assuming the exercise of these warrants. If approved, the THL Agreement and the Treasury Exchange Agreement would be revised to
reflect the increased size of the investment and certain other related technical matters.

The THL Transaction and the Treasury Exchange
Transaction (together with the other transactions contemplated thereby, the Recapitalization Transactions) are conditioned upon each other and on other closing conditions, including Sterling raising a total of at least $720 million
(inclusive of the THL investment), which would enable it to meet all of its regulatory capital requirements.

If the Recapitalization
Transactions are completed, in addition to the strategies described in Sterlings Annual Report on Form 10-K for the year ended December 31, 2009, Sterling plans to pursue a strategy of acquiring additional banks, through FDIC-assisted
transactions or otherwise. However, in order to be qualified to bid on FDIC-assisted transactions, Sterling must, among other things, work with its regulators to terminate the written agreements to which Sterling and Sterling Savings Bank are
subject. There can be no assurances that the Recapitalization Transactions can be completed or, even if completed, that this strategic goal will be achieved in a short time frame or even at all. See Risk FactorsWe cannot assure you
whether or when certain agreements entered into with our regulators will be lifted and Risk FactorsOur strategy of pursuing FDIC-assisted acquisition opportunities may not be successful.

Sterlings board of directors is in the process of identifying new candidates to serve on the board of directors following the completion of the
Recapitalization Transactions. The board currently expects that following the closing, the board of directors will be reconstituted and the number of directors will be reduced. The directors are expected to consist of the Chief Executive Officer, a
Chairperson, a representative of THL and a number of other current or new independent directors to be selected based on their expertise, backgrounds and other qualifications. Before any directors are appointed, our Nominating Committee must evaluate
the qualifications of each new and incumbent candidate and requisite regulatory approvals must be received. We currently expect that Scott Jaeckel, will be selected as THLs representative on the board. If appointed, Mr. Jaeckel would also
serve, subject to applicable eligibility rules, on the Personnel Committee and Governance Nominating Committee of the board. Sterling has not yet received regulatory approval to appoint Mr. Jaeckel to its board of directors and there can be no
assurance that the proposed Recapitalization Transactions will be completed or that Mr. Jaeckel will be appointed.

Executive Summary
and Highlights

Sterling reported a net loss attributable to common shareholders during the quarter ending March 31, 2010 of $88.8
million, or $1.71 per common share, which was an improvement over the fourth quarter 2009 results. Sterlings earnings per share and performance ratios continue to be impacted by the major disruption in the housing market and downturn in the
economy. Nonperforming assets increased $87.4 million during the quarter. However, the broader category of classified assets experienced a decline during the quarter. The provision for credit losses declined from the linked quarter with a decline in
charge-offs experienced. Sterling continues to grow and expand customer relationships as demonstrated by the growth in retail and public deposits during the quarter of $207.0 million. The decline in net interest income during the quarter reflected a
lower balance of earning assets and an increase in the amount of interest that was reversed which was related to nonperforming loans. Sterling continues to record a full valuation allowance against the future tax benefits of its operating losses,
and has implemented a shareholders rights plan to preserve this asset. As of March 31, 2010, Sterlings total risk-based capital ratio was 6.9%. Sterling continues to make progress towards its recapitalization, as demonstrated by the
agreements reached with the U.S. Treasury and THL. Liquidity enhancements during the quarter included increases in on-balance sheet liquidity, and a further lowering of the ratio of loans to deposits.

Critical Accounting Policies

The accounting and reporting policies of Sterling conform to accounting principles generally accepted in the United States of America
(GAAP) and to general practices within the banking industry. The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those estimates. Sterlings management has identified the accounting policies described below as those that, due to the judgments, estimates and assumptions inherent in those
policies are critical to an understanding of Sterlings Consolidated Financial Statements and Managements Discussion and Analysis.

Income Recognition.Sterling recognizes interest income by methods that conform to general accounting practices
within the banking industry. In the event management believes collection of all or a portion of contractual interest or principal on a loan has become doubtful, which generally occurs when the loan is 90 days past due or when Sterling restructures
it as a troubled loan, Sterling discontinues the accrual of interest, and any previously accrued interest recognized in income deemed uncollectible is reversed. Interest received on nonperforming loans is included in income only if principal
recovery is reasonably assured. A nonperforming loan is restored to accrual status when it is brought current, has performed in accordance with contractual terms for a reasonable period of time (generally at least six months), and the collectability
of the total contractual principal and interest is no longer in doubt.

Allowance for Credit Losses.The
allowance for credit losses is comprised of the allowance for loan losses and the reserve for unfunded credit commitments. In general, determining the amount of the allowance requires significant judgment and the use of estimates by management.
Sterling maintains an allowance for credit losses to absorb probable losses in the loan portfolio based on a quarterly analysis of the portfolio and expected future losses. This analysis is designed to determine an appropriate level and allocation
of the allowance for losses among loan types by considering factors affecting loan losses, including specific and confirmed losses, levels and trends in classified and nonperforming loans, historical loan loss experience, loan migration analysis,
current national and local economic conditions, volume, growth and composition of the portfolio, regulatory guidance and other relevant factors. Management monitors the loan portfolio to evaluate the adequacy of the allowance. The allowance can
increase or decrease each quarter based upon the results of managements analysis.

The portfolio is grouped into
standard industry categories for homogeneous loans based on characteristics such as loan type, borrower and collateral. Annual and quarterly loan migration to loss data is used to determine the probability of default. Historically, Sterling had used
both one-year and three-year losses to establish the expected loss rate on loans. During the fourth quarter of 2009, as a result of the higher loss rates experienced during 2009, Sterling began using losses from the most recent twelve months to
estimate the amount that would be lost if a default were to occur, which is termed the loss given default. The probability of default is multiplied by the loss given default to calculate the expected losses for each loan category.



26

##### Table of Contents

Individual loan reviews are based upon specific quantitative and qualitative criteria,
including the size of the loan, loan quality ratings, value of collateral, repayment ability of borrowers, and historical experience factors. The historical experience factors utilized and allowances for homogeneous loans (such as residential
mortgage loans, consumer loans, etc.) are collectively evaluated based upon historical loss experience, loan migration analysis, trends in losses and delinquencies, growth of loans in particular markets, and known changes in economic conditions in
each particular lending market.

A loan is considered impaired when, based on current information and events, it is probable
Sterling will be unable to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral
value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of
payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of delay, the reasons for the delay, the borrowers prior payment
record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loans effective interest rate,
the loans obtainable market price or the fair value of collateral if the loan is collateral dependent.

The fair value
of the underlying collateral for real estate loans, which may or may not be collateral dependent, is determined by using appraisals from qualified external sources. For commercial properties and residential development loans, the external appraisals
are reviewed by qualified internal appraisal staff to ensure compliance with appropriate standards and technical accuracy. Updated appraisals are ordered in accordance with regulatory provisions for extensions or restructurings of commercial or
residential real estate construction and permanent loans that have not performed within the terms of the original loan. Updated appraisals are also ordered for loans that have not been restructured, but that have stale valuation information,
generally defined in the current market as information older than six months, and deteriorating credit quality that warrants classification as substandard.

The timing of obtaining appraisals may vary, depending on the nature and complexity of the property being evaluated and the general
breadth of appraisal activity in the marketplace, but generally it is within 30 to 90 days of recognition of substandard status, following determination of collateral dependency, or in connection with a loans maturity or a negotiation that may
result in the restructuring or extension of a real estate secured loan. Delays in timing may occur to comply with actions such as a bankruptcy filing or provisions of an SBA guarantee.

Estimates of fair value may be used for substandard collateral dependent loans at quarter end if external appraisals are not expected to
be completed in time for determining quarter end results or to update values between appraisal dates to reflect recent sales activity of comparable inventory or pending property sales of the subject collateral. During the fourth quarter of 2009, as
a result of the large decline in real estate values during 2009, Sterling began to record a specific reserve for impaired loans for which an updated valuation analysis has not been completed within the last quarter. The specific reserve is
calculated by applying an estimated fair value adjustment to each loan based on market and property type. Estimates of value are not used to raise a value; however, estimates may be used to recognize deterioration of market values in quarters
between appraisal updates. The judgment with respect to recognition of any provision or related charge-off for a confirmed loss also takes into consideration whether the loan is collateral dependent or whether it is supported by sources of repayment
or cash flow beyond the collateral that is being valued. For loans that are deemed to be collateral dependent, the amount of charge-offs is determined in relation to the collaterals appraised value. For loans that are not deemed to be
collateral dependent, the amount of charge-offs may differ from the collaterals appraised value because there is additional support for the loan, such as cash flow from other sources.

While management uses available information to provide for loan losses, the ultimate collectability of a substantial portion of the loan
portfolio and the need for future additions to the allowance will be influenced by changes in economic conditions and other relevant factors. The current slowdown in economic activity and further declines in



27

##### Table of Contents

real estate values could continue to adversely affect cash flows for both commercial and individual borrowers, and as a result Sterling could experience further increases in nonperforming assets,
delinquencies and losses on loans. There can be no assurance that the allowance for credit losses will be adequate to cover all losses, but management believes the allowance for credit losses was adequate at March 31, 2010.

Investments and MBS.Assets in the investment and MBS portfolios are initially recorded at cost, which includes any
premiums and discounts. Sterling amortizes premiums and discounts as an adjustment to interest income over the estimated life of the security. The cost of investment securities sold, and any resulting gain or loss, is based on the specific
identification method. Sterlings MBS are primarily in agency securities, with limited investments in non-agency obligations. The majority of the municipal bonds that Sterling holds are all general obligation, spread throughout Sterlings
footprint. Sterling does not invest in collateralized debt obligations or similar exotic structured investment products.

The
loans underlying Sterlings MBS are subject to the prepayment of principal of the underlying loans. The rate at which prepayments are expected to occur in future periods impacts the amount of premium to be amortized in the current period. If
prepayments in a future period are higher or lower than expected, then Sterling will need to amortize a larger or smaller amount of the premium to interest income in that future period.

Management determines the appropriate classification of investment securities at the time of purchase. Held-to-maturity securities are
those securities that Sterling has the positive intent and ability to hold to maturity and are recorded at amortized cost. Available-for-sale securities are those securities that would be available to be sold in the future in response to
Sterlings liquidity needs, changes in market interest rates, and asset-liability management strategies, among other factors. Available-for-sale securities are reported at fair value, with unrealized holding gains and losses reported in
shareholders equity as a separate component of other comprehensive income, net of applicable deferred income taxes.

Management evaluates investment securities for other than temporary declines in fair value on a quarterly basis. If the fair value of
investment securities falls below their amortized cost and the decline is deemed to be other than temporary, the securities will be written down to current market value, resulting in a loss. There were no investment securities that management
identified to be other-than-temporarily impaired for the period ended March 31, 2010, because the decline in fair value of certain classes of securities was attributable to temporary disruptions of credit markets and the related impact on
securities within those classes, not deteriorating credit quality of specific securities. Sterling holds positions in classes of securities negatively impacted by temporary credit market disruptions, including a single-issuer trust preferred
security, and private label collateralized mortgage obligations. As of March 31, 2010, the trust preferred security is rated A1 by Moodys and has an amortized cost of $24.7 million compared to a $20.9 million market value, or an
unrealized loss of $3.8 million. As of March 31, 2010, the private label collateralized mortgage obligations had an aggregate amortized cost of $139.3 million compared to a $135.0 million market value, or an unrealized loss of $4.2 million. All
private label collateralized mortgage obligations are internally monitored monthly and independently stress-tested quarterly for both credit quality and collateral strength, and are investment grade according to at least one rating agency. As
of March 31, 2010, S&P had a rating of below investment grade on two of these securities, while Moodys maintained its investment grade rating on the same securities. At March 31, 2010, these two private label collateralized
mortgage obligations had an amortized cost of $46.4 million and a market value of $44.0 million. The vintage, or years of issuance, for these nonagency MBS ranges from 2003 to 2005. As of March 31, 2010, Sterling expects the return of
all principal and interest on all securities within the portfolios pursuant to the contractual terms, has the ability and intent to hold these investments, has no intent to sell securities that are deemed to have a market value impairment, and
Sterling does not believe it is more likely than not that it would be required to sell these investments before a recovery in market price occurs, or until maturity. Realized losses could occur in future periods due to a change in managements
intent to hold the investments to recovery, a change in managements assessment of credit risk, or a change in regulatory or accounting requirements.

Fair Value of Financial Instruments. Sterlings available-for-sale securities portfolio totaled $1.97 billion and
$2.16 billion as of March 31, 2010 and December 31, 2009, respectively, and were the majority of Sterlings financial instruments that are carried at fair value. These securities are valued using a pricing services matrix
technique based on quoted prices for similar instruments, which Sterling validates with non-binding broker quotes, in-depth collateral analysis and cash flow stress testing.

##### Table of Contents

Loans held for sale are also carried at fair value in order to match changes in the value of
the loans with the value of the economic hedges on the loans without having to apply complex hedge accounting. The fair value of loans held for sale is determined based upon an analysis of investor quoted pricing inputs.

Other Real Estate Owned. Prior to foreclosure, Sterling considers all viable alternatives, checks with the proper
authorities to ensure the existence of a valid and recorded lien on the property and determines the current market value of the collateral. Property and other assets acquired through foreclosure of defaulted mortgage or other collateralized loans
are carried at fair value, less estimated costs to sell the property and other assets. The fair value of OREO is generally determined using as is or disposition values from appraisals obtained by independent appraisers.

An allowance for losses on OREO is designed to include amounts for estimated losses as a result of impairment in value of the real
property after repossession. Sterling reviews its real estate owned for impairment in value at least quarterly or whenever events or circumstances indicate that the carrying value of the property or other assets may not be recoverable. In performing
the review, if the fair value, less selling costs, is less than its carrying value, an impairment loss is recognized as a charge to operating expenses.

Income Taxes. Sterling estimates income taxes payable based on the amount it expects to owe various taxing authorities.
Accrued income taxes represent the net estimated amount due to, or to be received from, taxing authorities. In estimating accrued income taxes, Sterling assesses the relative merits and risks of the appropriate tax treatment of transactions, taking
into account the applicable statutory, judicial and regulatory guidance in the context of Sterlings tax position. Sterling also considers recent audits and examinations, as well as its historical experience in making such estimates. Although
Sterling uses available information to record income taxes, underlying estimates and assumptions can change over time as a result of unanticipated events or circumstances. Penalties and interest associated with any potential estimate variances would
be included in income tax expense on the Consolidated Statement of Income.

Sterling uses an estimate of future earnings, and
an evaluation of its loss carryback ability and tax planning strategies to determine whether or not the benefit of its net deferred tax asset will be realized. Sterling has assessed whether it was more likely than not that it would realize the
benefits of its deferred tax asset. Sterling determined that the negative evidence associated with a projected three-year cumulative loss, the regulatory agreement in place between Sterling Savings Bank and the FDIC (the SSB Consent
Agreement) and between Sterling and the Federal Reserve Bank of San Francisco (the Reserve Bank Agreement), and continued credit deterioration in its loan portfolio outweighed the positive evidence. Therefore, a valuation allowance
was established against its deferred tax asset, with the allowance totaling $303 million as of March 31, 2010.

Results of Operations

Overview. Sterling reported a net loss attributable to common shareholders during the three months
ended March 31, 2010 of $88.8 million, or $1.71 per common share, compared with $24.8 million or $0.48 per common share during the three months ended March 31, 2009. The 2010 results included a provision for credit losses of $88.6 million,
compared with a provision of $65.9 million during the 2009 period. In addition to the increase in the credit loss provision year over year, the increase in net loss primarily reflects lower net interest income, a lower level of gains on the sale of
securities, and increased FDIC premiums.

Net Interest Income. The most significant component of earnings
for a financial institution typically is net interest income, which is the difference between interest income, primarily from loan, MBS and investment securities portfolios, and interest expense, primarily on deposits and borrowings. During the
three months ended March 31, 2010, net interest income was $74.9 million, as compared to $88.3 million, respectively, for the three months ended March 31, 2009. The decline in net interest income reflected the effects of
Sterlings higher level of non-performing assets, including non-accrual loans and other real estate owned (OREO), as well as a lower balance of average interest-earning assets.

##### Table of Contents

Changes in Sterlings net interest income are a function of changes in both rates and
volumes of interest-earning assets and interest-bearing liabilities. Net interest margin refers to net interest income divided by total average interest-earning assets and is influenced by the level and relative mix of interest-earning assets and
interest-bearing liabilities. The following table presents the composition of the change in net interest income, on a tax equivalent basis, for the periods presented. Municipal loan and bond interest income are presented gross of their applicable
tax savings. For each category of interest-earning assets and interest-bearing liabilities, the following table provides information on changes attributable to:

Net interest
income and net interest margin have been negatively affected by the increase in nonperforming assets. When loans reach nonperforming status, the reversal and cessation of accruing interest has an immediate negative impact on net interest margin.
During the first quarter of 2010, Sterling reversed interest income on non-performing loans of $23.2 million, representing 87 basis points, compared with $9.9 million, or 33 basis points for the first quarter of 2009. The effect of the growth in
nonaccrual interest on Sterlings net interest margin has been muted by the decline in funding costs. As of March 31, 2010, Sterling had reduced average deposit funding costs by 90 basis points compared with the first quarter of 2009.

##### Table of Contents

Provision for Credit Losses.Managements policy is to establish
valuation allowances for estimated losses by charging corresponding provisions against income. The evaluation of the adequacy of specific and general valuation allowances is an ongoing process. This process includes information derived from many
factors, including historical loss trends, trends in classified assets, trends in delinquent and non-accrual loans, trends in portfolio volume, diversification as to type of loan, size of individual credit exposure, current and anticipated economic
conditions, loan policies, collection policies and effectiveness, quality of credit personnel, effectiveness of policies, procedures and practices, and recent loss experience of peer banking institutions.

Sterling recorded provisions for credit losses of $88.6 million and $65.9 million for the three months ended March 31, 2010 and
2009, respectively. Sterling has increased its provision for credit losses in response to the level of classified loans, particularly in the multifamily and commercial construction, commercial real estate and commercial banking portfolios, and
increases in loss rates from reduced appraisal values. The following table summarizes the allowance for credit losses for the periods indicated:

##### Table of Contents

As of March 31, 2010, Sterling has recognized confirmed losses totaling $530.2 million
on collateral dependent nonperforming loans held in its portfolio. As a result of these confirmed losses, Sterling has written down the carrying value of these loans to the appraisal value of their underlying collateral. The loan loss coverage
ratio, excluding these loans for which the full loss to date has been charged off, was 169.0% of nonperforming loans at March 31, 2010. Further declines in real estate appraisal values could result in additional losses on these loans. The
following table presents nonperforming assets by type, and also by market for Sterlings nonperforming construction assets:

|(1) | Net of confirmed losses of $626.3 million for March 31, 2010, $579.7 million for December 31, 2009, and $244.0 million for March 31,
2009.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------

Nearly three quarters of the $87.4 million increase in nonperforming assets related to three
projects: one multi-family real estate relationship in Portland, Oregon; one commercial construction project in the Puget Sound region; and one multi-family construction project in the Puget Sound region. The increase in commercial real estate
during the quarter was comprised of several relationships throughout Sterlings geographic footprint. Declining balances of nonperforming residential construction assets, comprised predominately of non-owner occupied during the quarter and over
the last year, suggests that asset quality of the residential construction portfolio appears to have stabilized.

The decrease in noninterest income was primarily attributable to the lower level of gains on the sale of
securities. During the 2010 period, other noninterest income included a $3.4 million loss on the sale of $218.5 million of consumer indirect auto loans, while the 2009 period included a $1.1 million loss resulting from the failure of a Washington
state public depository bank. The 2009 mortgage banking results partially reflect the elevated levels of refinancing that were taking place at the time. Loan originations for the mortgage banking segment for the three months ended March 31,
2010 were down 39% from the 2009 level. However, the margin on residential loan sales expanded to 2.06% from 1.58% during the 2009 period. In the period ended March 31, 2010, bank owned life insurance (BOLI) included $699,000 of
gain in excess of cash surrender value on the proceeds of four policies. The change in loan servicing income is from valuation volatility of mortgage servicing rights.

The increase in non-interest expenses was mainly due
to an increase in Federal Deposit Insurance Corporation (FDIC) deposit insurance premiums, expenses related to increased credit resolution costs and OREO operations, and expenses associated with Sterlings recapitalization efforts.

Income Tax Provision. Sterling did not record a federal and state income tax benefit for the three months ended
March 31, 2010, and did record a benefit of $436,000 for the three months ended March 31, 2009. Sterlings effective tax rate reflects the full valuation allowance Sterling is recording against tax benefits being incurred. This
allowance totaled $303.0 million as of March 31, 2010.

Financial Position

Assets. At March 31, 2010, Sterlings assets were $10.55 billion, down $322.9 million from
$10.88 billion at December 31, 2009, with decreases in the loan and securities portfolios partially offset by an increase in cash balances reflecting an increase in on-balance sheet liquidity.

Investment Securities and MBS. Sterlings investment and MBS portfolio at March 31, 2010 was $1.99 billion,
a decrease of $191.6 million from the December 31, 2009 balance of $2.18 billion, due to principal repayments, maturities and sales. On March 31, 2010, the investment and MBS portfolio had an unrealized gain of $42.0 million
versus $25.8 million at December 31, 2009.

Loans Receivable. At March 31, 2010, net loans receivable were $6.75
billion, compared to $7.34 billion at December 31, 2009. The contraction in Sterlings loan portfolio reflects charge-offs, a lessening of demand for credit, and capital management. The following table sets forth the composition of
Sterlings loan portfolio as of the dates indicated:

While mortgage refinancing has slowed versus 2009,
originations of residential real estate mortgage loans primarily sold in the secondary markets totaled $431.1 million. This and Sterlings other loan production results reflect Sterlings lending initiatives to support and restore economic
growth and development in the communities it serves. Sterlings lending initiatives focus on funding affordable housing, small business loans and financing programs to support business growth.

The reduction in the average deposit funding costs by 31 basis points from the fourth quarter of 2009
reflects the reduction in brokered deposits of $357.0 million since December 31, 2009, and the increase in retail and public deposits of $207.0 million. As a result of the SSB Consent Agreement, Sterling Savings Bank is currently precluded from
accepting additional brokered deposits, or renewing existing brokered deposits. Regular payments on loans and MBS, as well as increases in retail deposits and sales of MBS and other investment securities, currently provide Sterling with sufficient
liquidity to meet its payment obligations on the brokered deposits as they mature. The shift in the deposit mix also reflects Sterlings ability to increase its customer base and the ongoing success of its strategy to grow and strengthen
relationships with customers and the communities it serves. During the quarter, the total number of transaction accounts increased 3% on an annualized basis.

Subsequent to March 31, 2010, the FDIC extended the term of its voluntary Transaction Account Guarantee (TAG) program
through December 31, 2010. Under this program, noninterest-bearing transaction accounts and qualified NOW checking accounts are fully guaranteed by the FDIC for an unlimited amount of coverage. The coverage under the TAG program is in addition
to, and separate from, the coverage available under the FDICs general deposit insurance protection. Sterling will continue to participate in this program.

Borrowings. Deposit accounts are Sterlings primary source of funds. Sterling does, however, rely upon advances from
the Federal Home Loan Bank (FHLB), reverse repurchase agreements and other borrowings to fund assets and meet deposit withdrawal requirements. During the three months ended March 31, 2010, these borrowings decreased
$93.9 million, consistent with Sterlings strategy of reducing total assets to manage its capital position.

Asset and Liability
Management

The results of operations for financial institutions have been and may continue to be materially and adversely
affected by changes in prevailing economic conditions, including changes in interest rates, declines in real estate market values and the monetary and fiscal policies of the federal government. The mismatch between maturities, interest rate
sensitivities and prepayment characteristics of assets and liabilities, and the changes in each of these attributes under different interest rate scenarios results in interest-rate risk.

Sterling, like most financial institutions, has material interest-rate risk exposure to changes in both short-term and long-term interest
rates as well as variable interest rate indices. Sterlings results of operations are largely dependent upon its net interest income and its ability to manage its interest rate risk.

The Asset/Liability Committees (ALCO) manage Sterlings subsidiary banks interest-rate risk based on interest rate
expectations and other factors within policies and practices approved by their respective Board of Directors. The principal objective of the asset and liability management activities is to provide maximum levels of net interest income while
maintaining acceptable levels of interest-rate risk and liquidity risk while facilitating funding needs. ALCO manages this process at both the subsidiary and consolidated levels. ALCO measures interest rate risk exposure through three primary
measurements: management of the relationship between its interest bearing assets and its interest bearing liabilities, interest rate shock simulations of net interest income, and economic value of equity (EVE) simulation.

##### Table of Contents

The difference between a financial institutions interest rate sensitive assets and
interest rate sensitive liabilities is referred to as the interest rate sensitivity gap. An institution having more interest rate sensitive assets than interest rate sensitive liabilities within a given time period is said to be
asset sensitive, which generally means that if interest rates increase (other things being equal), a companys net interest income will increase and if interest rates decrease (other things being equal), its net interest income will
decrease. The opposite is true for an institution that is liability sensitive. As of March 31, 2010, Sterling was asset sensitive, under the most likely interest rate scenario. The most likely interest rate
scenario is an interest rate forecast provided by IHS Global Insight predicting likely future interest rate behavior based on their assessment of current economic conditions, patterns and projections. The most likely interest rate scenario applied
in Sterlings gap analysis forecasts the prime interest rate rising 100 basis points after one year and 125 basis points after two years. This interest rate scenario results in the Treasury yield curve flattening over a two-year period
primarily from faster increases in short term interest rates relative to the rate of increase in longer term interest rates.

ALCO uses interest rate shock simulations of net interest income to measure the effect of changes in interest rates on the net interest
income for Sterling over a 12 month period. This simulation consists of measuring the change in net interest income over the next 12 months from a base case scenario when rates are shocked, in a parallel fashion, up and down. The base case uses the
assumption of the existing balance sheet and existing interest rates to simulate the base line of net interest income over the next 12 months. The simulation requires numerous assumptions, including relative levels of market interest rates,
instantaneous and parallel shifts in the yield curve, loan prepayments and reactions of depositors to changes in interest rates, and should not be relied upon as being indicative of actual or future results. Results can differ from the most likely
rate scenario due to the amount and timing of interest rate movements, which can impact the rate of prepayments, as well as other variables in the model. The analysis does not contemplate actions Sterling may undertake in response to changes in
interest rates and market conditions. The results of this simulation as of March 31, 2010 and December 31, 2009 are included in the following table:

##### Table of Contents

ALCO uses EVE simulation analysis to measure risk in the balance sheet that might not be
taken into account in the net interest income simulation analysis. Whereas net interest income simulation highlights exposure over a relatively short time period of 12 months, EVE simulation analysis incorporates all cash flows over the estimated
remaining life of all balance sheet positions. The EVE simulation analysis of the balance sheet, at a point in time, is defined as the discounted present value of asset cash flows minus the discounted value of liability cash flows. The discount
rates that are used represent an assumption for the current market rates of each group of assets and liabilities. The difference between the present value of the asset and liability represents the EVE. As with net interest income, this is used as
the base line to measure the change in EVE when interest rates are shocked, in a parallel fashion, up and down. As with the net interest income simulation model, EVE simulation analysis is based on key assumptions about the timing and variability of
balance sheet cash flows. However, because the simulation represents much longer time periods, inaccuracy of assumptions may increase the variability of outcomes within the simulation. It also does not take into account actions management may
undertake in response to anticipated changes in interest rates. The results of this simulation at March 31, 2010 and December 31, 2009 are included in the following table:

As of March 31, 2010, Sterling has customer-related
interest rate swap derivatives outstanding. For a description, see  Off-Balance Sheet Arrangements and Aggregate Contractual Obligations. As of March 31, 2010, Sterling has not entered into any other derivative transactions as
part of managing its interest rate risk. However, Sterling continues to consider derivatives, including non-customer related interest rate swaps, caps and floors as viable alternatives in the asset and liability management process.

Liquidity and Capital Resources

Sterlings primary sources of funds are: retail, public and brokered deposits; borrowings from commercial banks, the FHLB, and the
Federal Reserve; the collection of principal and interest primarily from loans, as well as from mortgage backed securities; and the sale of loans into the secondary market in connection with Sterlings mortgage banking activities. Sterling
Savings Bank and Golf Savings Bank actively manage their liquidity in an effort to maintain an adequate margin over the level necessary to support the funding of loans and deposit withdrawals. Liquidity may vary from time to time, depending on
economic conditions, deposit fluctuations, loan funding needs and regulatory sanctions. Pursuant to the SSB Consent Agreement, Sterling Savings Bank must comply with limitations on the interest rate it may pay on deposits and cannot accept or renew
brokered deposits. The restriction from accepting additional brokered deposits, or renewing existing brokered deposits has not had a material adverse effect on Sterlings liquidity. Sterling supplements its retail deposit gathering by
soliciting deposits from public entities. Public deposits are generally obtained by competitive rate offerings and bidding among qualifying financial institutions. In 2009, certain states increased the collateralization requirements for uninsured
public deposits. The increased collateralization requirements required that Sterling pledge additional collateral when accepting uninsured public deposits, which reduced Sterlings collateral available for borrowing or sale.

Sterling uses wholesale funds to supplement deposit gathering for funding the origination of loans or purchasing assets such as MBS and
investment securities. These borrowings include advances from the FHLB, reverse

repurchase agreements, primary and secondary credits and term auction facilities from the Federal Reserve, and federal funds purchased. Sterling had access to $2.91 billion and $2.69 billion of
additional liquidity from all sources, including loans held for sale and federal income taxes receivable, as of March 31, 2010 and December 31, 2009, respectively. Sterling Savings Bank and Golf Savings Bank have credit lines with
FHLB of Seattle that provide for borrowings up to a percentage of each of their total assets, subject to collateralization requirements. At March 31, 2010 and December 31, 2009, these credit lines represented a total borrowing capacity of
$2.36 billion and $2.43 billion, of which $890.2 million and $967.5 million was available, respectively. In the first quarter of 2010, Sterling Savings Bank started transitioning from a blanket pledge collateral agreement with the FHLB of Seattle to
a custodial agreement. Additionally, Sterlings future borrowings from the FHLB of Seattle are limited to overnight cash management advances (CMA), which automatically rollover each day. Sterling Savings Bank has the ability to
increase or decrease the CMA borrowings on a daily basis. At both March 31, 2010 and December 31, 2009, Sterling had $1.03 billion in outstanding borrowings under reverse repurchase agreements, respectively. Sterling had unpledged
securities available for additional secured borrowings of approximately $473.1 million and $682.1 million as of March 31, 2010 and December 31, 2009, respectively.

Reverse repurchase agreements allow Sterling to sell investments (generally U.S. agency securities and MBS) under an agreement to buy
them back at a specified price at a later date. These agreements to repurchase are deemed to be borrowings collateralized by the investments and MBS sold. The use of reverse repurchase agreements may expose Sterling to certain risks not
associated with other borrowings, including interest rate risk and the possibility that additional collateral may have to be provided if the market value of the pledged collateral declines. The terms of certain of Sterlings borrowings and
reverse repurchase agreements that Sterling has entered into, impose various requirements on Sterling, including the requirement to remain well capitalized. As a result of the SSB Consent Agreement and being undercapitalized, Sterling could be
required to repay, prior to their maturity, up to $1.00 billion of reverse repurchase agreements. As of March 31, 2010, if these borrowings had been terminated early, the settlement costs would have been approximately $78 million. The
market value of the collateral securing these borrowings was $1.15 billion as of March 31, 2010. This collateral, if sold, may result in securities gains that could mitigate the settlement costs. Should these actions occur,
Sterlings interest costs would be reduced and these actions may improve its Tier 1 leverage capital ratio in the future, although there can be no assurance that these improvements will occur. At March 31, 2010, Sterling also had $3.0
million of borrowings in the form of a subordinated debenture. While the debenture remains in place in accordance with its original terms, it bears a default rate of interest of 7.75% since Sterling has defaulted on certain covenants regarding
regulatory actions and remaining well capitalized.

As of March 31, 2010 and December 31, 2009, Sterling also had $0
and $16.7 million, respectively, of discount window borrowings, which are short-term borrowings from the Federal Reserve. Through the Federal Reserves 12th District Bank, Sterling Savings Bank participates in the Borrower in Custody Program
which allows Sterling Savings Bank to borrow against certain pledged loans on an overnight basis. Golf Savings Bank can borrow under the Borrower in Custody Program for terms ranging from overnight to 90 days. Golf Savings Bank is also eligible to
participate in the Term Auction Facility, which allows Golf Savings Bank to bid on funds to be borrowed for terms of 28 to 84 days. Following receipt of the SSB Order, Sterling may be required to provide a higher level of collateral for any funds
that Sterling borrows from the Federal Reserve or its other funding sources. Any additional collateral requirements or limitations on Sterlings ability to access additional funding sources are expected to have a negative impact on
Sterlings liquidity.

Sterling, on a parent company-only basis, had cash of approximately $21.1 million and $24.3
million at March 31, 2010 and December 31, 2009, respectively. Sterling received cash dividends from Sterling Savings Bank of $0 and $6.4 million during the three months ended March 31, 2010 and 2009, respectively, and from Golf
Savings Bank of $0 and $240,000 for the same respective periods. Sterling Savings Banks and Golf Savings Banks ability to pay dividends is generally limited by their earnings, financial condition, capital requirements, and applicable
regulatory requirements. As of March 31, 2010, Sterlings subsidiary banks were not paying dividends to Sterling.

The availability and cost of capital is partially dependent on Sterlings credit ratings. During the first quarter of 2010, Fitch
Ratings (Fitch) downgraded Sterlings long term issues default rating to C from CCC citing concerns over Sterlings ability to raise capital. The SSB Consent Agreement requires Sterling to raise at least $300 million of capital
and thereafter maintain a Tier 1 leverage ratio of not less than 10% by December 15, 2009. Subsequent to

March 31, 2010, as part of the companys recapitalization efforts, Sterling entered into the THL Agreement and the Treasury Exchange Agreement. See  Recent
Developments above for further detail. Successful completion of the recapitalization transactions are expected to return Sterling to well capitalized status, but there can be no assurance that Sterling will be successful in this regard. See
Note 14 of Notes to Consolidated Financial Statements, and  Recent Developments and  Risk Factors.

Off-Balance Sheet Arrangements and Aggregate Contractual Obligations

Sterling, in the conduct of ordinary business operations routinely enters into contracts for services. These contracts may require payment
for services to be provided in the future and may also contain penalty clauses for the early termination of the contracts. Sterling is also party to financial instruments with off-balance sheet risk in the normal course of business to meet the
financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Management does not believe that these off-balance sheet arrangements have a material current effect on Sterlings
financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources but there is no assurance that such arrangements will not have a future effect.

The reserve for unfunded commitments as of March 31, 2010 was $12.3 million, and as of December 31, 2009 was
$21.3 million, with the decline due to Sterling reducing the amount of unfunded commitments on nonperforming loans. The adequacy of the reserve for unfunded commitments is evaluated on a quarterly basis.

As part of its mortgage banking activities, Sterling issues interest rate lock commitments to prospective borrowers on residential
mortgage loan applications. Pricing for the sale of these loans is fixed with various qualified investors under both non-binding (best-efforts) and binding mandatory) delivery programs. For mandatory delivery programs,
Sterling hedges interest rate risk by entering into offsetting forward sale agreements on MBS with third parties. Risks inherent in mandatory delivery programs include the risk that if Sterling does not close the loans subject to interest rate lock
commitments, it is nevertheless obligated to deliver MBS to the counterparty under the forward sale agreement. Sterling could incur significant costs in acquiring replacement loans or MBS and such costs could have a material adverse effect on
mortgage banking operations in future periods.

Interest rate lock commitments and loan delivery commitments are off balance
sheet commitments that are considered to be derivatives. As of March 31, 2010, Sterling had $200.8 million of interest rate lock commitments, $96.6 million of warehouse loans held for sale that were not committed to investors, and held
offsetting forward sale agreements on MBS valued at $301.5 million. In addition, Sterling had mandatory delivery commitments to sell mortgage loans to investors valued at $42.5 million as of March 31, 2010. As of December 31, 2009,
Sterling had $110.0 million of interest rate lock commitments, $119.7 million of warehouse loans held for sale that were not committed to investors, and held offsetting forward sale agreements on MBS valued at $234.0 million. In addition,
Sterling had mandatory delivery commitments to sell mortgage loans to investors valued at $29.5 million as of December 31, 2009. As of March 31, 2010 and December 31, 2009, Sterling had entered into best efforts forward commitments to
sell $19.6 million and $51.6 million of mortgage loans, respectively.

In the normal course of business, Sterling enters into
interest rate swap transactions with loan customers. The interest rate risk on these swap transactions is managed by entering into offsetting interest rate swap agreements with various counterparties (broker-dealers or
dealers). The counterparty swap agreements include certain representations, warranties and covenants, which include terms that allow for an early termination in the event of default. Failure to maintain a well capitalized position is one
event that may be considered a default, and counterparties to the swap agreements could require an early termination settlement or an increase in the collateral to secure derivative instruments that are in net liability positions to
Sterling. The early termination provision of the swap agreements could result in Sterling reimbursing the counterparty and recording a charge equal to the current market value of the swap agreement if terminated. During the
three months ended March 31, 2010, no counterparties declared an early termination event. The aggregate fair value of all derivative instruments with credit risk related contingent features that are in a liability position on March 31,
2010 was $4.5 million for which Sterling had already posted collateral with a market value of $5.4 million. Both customer and dealer related interest rate derivatives are carried at fair value by Sterling.

Capital

Sterlings total shareholders equity was $245.5 million at March 31, 2010, compared with $323.2 million at
December 31, 2009, with the decrease reflecting the net loss available to common shareholders, partially offset by a gain on the available for sale securities portfolio. Shareholders equity was 2.33% of total assets at March 31,
2010, compared with 2.97% at December 31, 2009. At March 31, 2010, Sterling had a net unrealized gain of $42.0 million on investment securities and MBS classified as available for sale, as compared to a net unrealized gain of $25.8 million
as of December 31, 2009. Fluctuations in prevailing interest rates are expected to cause volatility in this component of accumulated comprehensive income or loss in shareholders equity.

Sterling has outstanding various series of Trust Preferred Securities issued to investors. The Trust Preferred Securities are treated as
debt of Sterling, and qualify as Tier 1 capital, subject to certain limitations. During the third quarter of 2009, Sterling elected to defer payments of interest on the Junior Subordinated Debentures. Under the terms of the Debentures, Sterling
is permitted to defer such payments for up to 20 consecutive quarterly periods without triggering an event of default. In February 2010, Sterling commenced cash offers to redeem its trust preferred borrowings at $0.20 of par. These offers to
repurchase expired unfilled.

Sterling, Sterling Savings Bank and Golf Savings Bank are required by applicable regulations to
maintain certain minimum capital levels. At March 31, 2010, Sterling was not adequately capitalized. Under the terms of the SSB Consent Agreement and the Reserve Bank Agreement, Sterling has agreed to, among other things, raise
capital, and maintain a Tier 1 leverage ratio of not less than 10%. Subsequent to March 31, 2010, as part of the companys recapitalization efforts, Sterling reached agreements with the U.S. Treasury and THL. See - Recent
Developments and Note 14 of Notes to Consolidated Financial Statements. The following table sets forth the respective capital positions for Sterling, Sterling Savings Bank and Golf Savings Bank as of March 31, 2010:

New Accounting
Pronouncements

In May 2009, the FASB issued guidance on subsequent events that standardizes accounting for and disclosures
of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. In February 2010, the FASB amended its guidance on subsequent events. As a public reporting company, Sterling is required to
evaluate subsequent events through the date its financial statements are issued. The adoption of these rules did not have a material impact on Sterlings consolidated financial statements.

In June 2009, the FASB issued standards on accounting for transfers of financial assets, removing the concept of qualifying
special-purpose entities as an accounting criteria that had provided an exception to consolidation, and provided additional guidance on requirements for consolidation. This guidance became effective for Sterling on January 1, 2010, and did not
have a material impact on its consolidated financial statements.

##### Table of Contents

In January 2010, the FASB issued guidance on considerations related to implementation of
fair value measurement disclosures. This update to the codification specifically addresses: 1) transfers between levels 1, 2 and 3 of the fair value hierarchy; 2) level of disaggregation of derivative contracts for fair value measurement
disclosures; and 3) disclosures about fair value measurement inputs and valuation techniques. This guidance became effective for Sterling on March 31, 2010, and did not have a material impact on its consolidated financial statements.

Regulation and Compliance

In addition to the Reserve Bank Agreement and the SSB Consent Agreement entered into during the fourth quarter of 2009, Sterling, as a
bank holding company, is subject to ongoing comprehensive examination and regulation by the Federal Reserve, and Sterling Savings Bank, as a Washington State-chartered bank, and Golf Savings Bank, as a Washington State-chartered savings bank, are
subject to ongoing comprehensive regulation and examination by the Washington Department of Financial Institutions and the FDIC. Sterling Savings Bank and Golf Savings Bank are further subject to standard Federal Reserve regulations related to
deposit reserves and certain other matters.

Forward-Looking Statements

From time to time, Sterling and its executive management have made and will make forward-looking statements that are not historical facts
and that are intended to be covered by the safe harbor for forward-looking statements provided by the Private Securities Litigation Reform Act of 1995. These forward-looking statements may include, but are not limited to, statements
about Sterlings plans, objectives, expectations and intentions and other statements contained in this release that are not historical facts and pertain to Sterlings future operating results. When used in this report, the words
expects, anticipates, intends, plans, believes, seeks, estimates and similar expressions are generally intended to identify forward-looking statements. We make
forward-looking statements regarding projected sources of funds, use of proceeds, availability of acquisition and growth opportunities, ability to repay government funds, payment of dividends, adequacy of our allowance for loan and lease losses and
provision for loan and lease losses, our real estate portfolio and subsequent charge-offs. Such statements may be contained in this report and in other documents that Sterling files with the Securities and Exchange Commission. Such statements may
also be made by Sterling and its executive management in oral or written presentations to analysts, investors, the media and others.

Actual results may differ materially from the results discussed in these forward-looking statements because such statements are
inherently subject to significant assumptions, risks and uncertainties, many of which are difficult to predict and are generally beyond Sterlings control. These include but are not limited to:

Disclosure Controls and Procedures

Sterlings management, with the participation of Sterlings principal executive officer and principal financial officer, has
evaluated the effectiveness of Sterlings disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of 1934 (the Exchange Act) as of the end of the period
covered by this report. Based on such evaluation, Sterlings principal executive officer and principal financial officer have concluded that, as of the end of such period, Sterlings disclosure controls and procedures are effective in
recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by Sterling in the reports that it files or submits under the Exchange Act.

Changes in Internal Control Over Financial Reporting

There were no changes in Sterlings internal control over financial reporting that occurred during the fiscal quarter to which this
report relates that have materially affected, or are reasonably likely to materially affect, Sterlings internal control over financial reporting.

Class Action Litigation

On December 11, 2009, a putative securities class action complaint was filed in the United
States District Court for the Eastern District of Washington against Sterling and certain of our current and former officers. The complaint alleges that the defendants violated sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC
Rule 10b-5 by making false and misleading statements concerning our business and financial results. The complaint alleges that defendants failed to disclose the extent of Sterlings delinquent commercial real estate, construction and land
loans, properly record losses for impaired loans, properly reserve for loan losses, and properly account for our goodwill and deferred tax assets. The complaint seeks, on behalf of persons who purchased our common stock during the period from
July 23, 2008 to January 13, 2009, damages of an unspecified amount and attorneys fees and costs. Failure by Sterling to obtain a favorable resolution of the claims set forth in the complaint could have a material adverse effect on
our business, results of operations and financial condition. Currently, the amount of such material adverse effect cannot be reasonably estimated.

ERISA Class Action Litigation

On January 20 and 22, 2010, two putative class action complaints were filed in the United States District Court for the Eastern
District of Washington against Sterling and certain of our current and former officers and directors. The complaints allege that defendants violated sections 404 and 405 of the Employee Retirement Income Security Act of 1974, as amended
(ERISA), by breaching their fiduciary duties to participants in the Sterling Savings Bank Employee Savings and Investment Plan and Trust (the Plan). The complaints allege that defendants breached their fiduciary duties from
July 23, 2008 to the date the complaints were filed by investing Plan assets in Sterlings securities when defendants knew or should have known that the price of Sterlings securities were inflated because Sterling had failed to
disclose the extent of Sterlings delinquent commercial real estate, construction and land loans, properly record losses for impaired loans, properly reserve for loan losses, and properly account for our goodwill and deferred tax assets. The
complaints seek damages of an unspecified amount and attorneys fees and costs. Failure by Sterling to obtain a favorable resolution of the claims set forth in the complaints could have a material adverse effect on our business, results of
operations and financial condition. Currently, the amount of such material adverse effect cannot be reasonably estimated.

Derivative Class
Action Litigation

On February 10, 2010, a shareholder derivative action was filed in the Superior Court for Spokane
County, Washington, allegedly on behalf of and for the benefit of Sterling, against certain of our current and former officers and directors. The complaint alleges, among other claims, breach of fiduciary duty, waste of corporate assets, and unjust
enrichment. The complaint names Sterling as a nominal defendant. The complaint seeks unspecified damages, restitution, disgorgement of profits, equitable and injunctive relief, attorneys fees, costs, and expenses. The complaint alleges that
the individual defendants failed to prevent Sterling from issuing improper financial statements, maintain a sufficient allowance for loan and lease losses, and establish effective credit risk management and oversight mechanisms regarding
Sterlings commercial real estate, construction and land development loans, losses and reserves recorded for impaired loans, and accounting for goodwill and deferred tax assets. Because the complaint is derivative in nature, it does not seek
monetary damages from Sterling. However, Sterling may be required throughout the pendency of the action to advance the legal fees and costs incurred by the individual defendants and to incur other financial obligations, which could have a material
adverse effect on our business, results of operations and financial condition. Currently, the amount of such material adverse effect cannot be reasonably estimated.



|Item 1a | Risk Factors
|------- | ------------

You
should carefully consider the risks and uncertainties we describe both in this Report and in our Annual Report on Form 10-K for the fiscal year ended December 31, 2009, before deciding to invest in, or retain, shares of our

common stock. These are not the only risks and uncertainties that we face. Additional risks and uncertainties that we do not currently know about or that we currently believe are immaterial, or
that we have not predicted, may also harm our business operations or adversely affect us. If any of these risks or uncertainties actually occurs, our business, financial condition, operating results or liquidity could be materially harmed.

The following risk factors update, and should be read together with, the risk factors set forth in our Annual Report on Form 10-K for the
fiscal year ended December 31, 2009.

If we fail to consummate the proposed Recapitalization Transactions or otherwise fail to
raise sufficient capital, our ongoing financial viability would be in doubt.

The agreements related to the proposed Recapitalization
Transactions are subject to numerous conditions, many of which are outside of our control and might not be fulfilled. These include, among others, the receipt of gross proceeds of at least $720 million in connection with the Recapitalization
Transactions (inclusive of the THL Transaction), receipt of regulatory approvals and third-party consents, Sterlings maintenance of asset levels and capital ratios, the absence of material changes in the characteristics of our loan portfolio,
no occurrence of an ownership change that would affect the preservation of certain deferred tax assets of Sterling and no occurrence of a material adverse effect. The THL Agreement may be terminated in the event that the closing does not
occur on or before September 1, 2010; however, we cannot assure you that the Recapitalization Transactions will close in the near term or at all. If we fail to consummate the proposed Recapitalization Transactions or otherwise fail to raise
sufficient capital, our ongoing financial viability would be in doubt and we may file for bankruptcy and/or our banking subsidiaries may enter into FDIC receivership. Even if we were to consummate the proposed Recapitalization Transactions, we may
need to raise additional capital and there can be no assurance that we would be able to do so in the amounts required and in a timely manner, or at all. Failure to raise sufficient capital could subject us to further regulatory restrictions or
penalties.

The proposed Recapitalization Transactions, if completed, will dilute your ownership, prevent the payment of dividends and
may adversely affect the market price of our Common Stock.

The proposed Recapitalization Transactions involve sales of a substantial
number of shares of our Common Stock and other securities potentially convertible into Common Stock. If the Recapitalization Transactions are completed, current shareholders will have no more than a minimal stake in Sterling. As a result of the sale
of such a large number of shares of our equity securities, the market price of our Common Stock could decline.

Even after the completion of
the proposed Recapitalization Transactions, we may decide to raise additional funds through public or private debt or equity financings for a number of reasons, including in response to regulatory or other requirements to meet our liquidity and
capital needs as discussed above, to finance our operations and business strategy (including potential acquisitions) or for other reasons. If we raise funds by issuing equity securities or instruments that are convertible into equity securities, the
percentage ownership of our existing shareholders will further be reduced, the new equity securities may have rights, preferences and privileges superior to those of our Common Stock, and the market of our Common Stock could decline.

In addition, there are anti-dilution adjustments in the warrants and preferred stock to be issued in the proposed Recapitalization Transactions. There is
no such protection available to holders of our Common Stock. To the extent that any new issuance of equity securities triggers these anti-dilution adjustments, your ownership would be further diluted.

Pursuant to the terms of the TARP Exchange, we will be unable to pay dividends on Common Stock without the Treasurys consent prior to the earlier
of December 5, 2011 and the date on which we redeem (or Treasury transfers to unaffiliated parties) all of the shares held by Treasury after the consummation of the TARP Exchange.

PART II  Other Information



We may be required to pay dividends to THL if our shareholders do not timely approve the proposal
necessary to allow the conversion of preferred stock issued to THL in connection with the Recapitalization Transactions into Common Stock.

If the proposed Recapitalization Transactions are completed, we will issue preferred stock to THL and certain other institutions. Pursuant to its terms,
the preferred stock issued in connection with the Recapitalization Transactions will not convert into Common Stock until our shareholders have approved an amendment to our restated Articles of Incorporation to increase the number of authorized
shares of our Common Stock to a number at least sufficient to permit the full conversion of such preferred stock into our Common Stock (the Common Stock Amendment). As a result, we have agreed to use our reasonable best efforts to
promptly hold a special meeting after the closing of Recapitalization Transactions, at which we will seek to obtain the requisite shareholder approval. In the event that the Common Stock Amendment is not approved by shareholders within 120 days of
the closing of the THL Transaction, THL will be entitled to cumulative cash dividends at a per annum rate of 15% on the stated amount per share of preferred stock issued to THL, payable quarterly in arrears commencing on the 120th day following
closing.

We cannot assure you whether or when certain agreements entered into with our regulators will be lifted, even if we complete
the proposed Recapitalization Transactions.

Even if we complete the proposed Recapitalization Transactions, we cannot assure you
whether or when the SSB Consent Agreement and the Reserve Bank Agreement, as described in our Form 10-K, will be lifted or terminated. Even if lifted or terminated, we may still be subject to memoranda of understanding or other agreements with
regulators that restrict our activities. For additional information see the risk factor in our Form 10-K titled Our banking subsidiary, Sterling Savings Bank, has entered into a consent agreement with the FDIC and the WDFI, and Sterling has
entered into a written agreement with the Federal Reserve.

Our strategy of pursuing FDIC-assisted acquisition opportunities
following the completion of the proposed Recapitalization Transactions may not be successful.

If the proposed Recapitalization
Transactions are completed, we anticipate that a part of our future business strategy will be to pursue the acquisition of failed banks that the FDIC plans to place in receivership. We are not currently qualified to bid on these transactions. There
can be no assurance that we will be successful in the near term or at all. Prolonged or indefinite failure to achieve such qualification could cause us to miss the opportunity to bid on banks that we believe would be attractive acquisition
candidates. Even if we become qualified to bid on these transactions, the FDIC may not place banks that meet our strategic objectives into receivership. The bidding process for failing banks could become very competitive, and the FDIC does not
provide information about bids until after the failing bank is closed. Sterling may not be able to match or beat the bids of other acquirers unless it bids aggressively by increasing the premium paid on assumed deposits, reducing the discount bid on
assets purchased or taking other actions, any of which could make the acquisition less attractive.

The FDIC Policy Statement will limit
our ability to acquire failed banks.

As the agency responsible for resolving failed depository institutions, the FDIC has discretion
to determine whether a party is qualified to bid on a failed institution. The FDIC Policy Statement imposes additional restrictions and requirements on certain private investors and institutions, to the extent that those investors or
institutions seek to acquire a failed institution from the FDIC. These include, among others, a requirement that certain private investors in those institutions agree to a three-year transfer restriction on their shares. Since its initial adoption
on August 26, 2009, the FDIC has issued several interpretations which have modified the Policy Statement and the FDIC may change it in the future. On April 23, 2010, the FDIC issued an interpretation that would permit a recapitalized
institution (such as Sterling if the proposed Recapitalization Transactions are completed) to acquire failed banks without being subject to the FDIC Policy Statement, provided the assets of the failed banks acquired during the 18 months following
the current recapitalization transaction do not exceed 100% of the total assets of the recapitalized institution. It is not clear, based on the current FDIC Policy Statement, whether the total assets are measured by Sterlings assets at the
holding company level or at the bank subsidiary level. In addition, it is not clear how the FDIC would calculate percentage of assets, and whether that percentage is based on assets at the time of the recapitalization or whether the percentage is
based on growth or contraction in an institution over time.

PART II  Other Information



Sterling expects to bid on failed banks as a key component of its strategy, if and when
it is permitted to do so by its regulators as described in the preceding risk factor and assuming that the proposed Recapitalization Transactions are completed. Sterling does not anticipate taking any action that would subject stockholders to the
terms of the FDIC Policy Statement, which may limit Sterlings ability to pursue attractive acquisition opportunities and harm its competitive position.

If the proposed Recapitalization Transactions are completed, it is possible that Sterling might wish to engage in an acquisition that
could trigger applicability of the FDIC Policy Statement to it and to certain of its stockholders as a result of the size of a potential acquisition or possible changes to the FDIC Policy Statement. Were it to apply, Sterling would be required to
maintain a ratio of Tier 1 common equity to total assets of at least 10% for a period of three years following a failed bank acquisition, and thereafter, so long as such stockholders continue to hold their investment in Sterling, to maintain a
capital level sufficient to be well capitalized under FDIC rules and regulations. Further, certain stockholders might be required to agree to hold their shares for three years, provide certain information to the FDIC and agree to certain
other restrictions. Sterling does not intend to make any such acquisition absent the consent of those stockholders to whom the FDIC Policy Statement would apply, and there can be no assurance that any such consent could be obtained. If Sterling is
able to obtain requisite stockholder consent to be bound by the Policy Statement and enters into such transactions, its operating flexibility could be harmed by having to comply with the other requirements set forth in the Policy Statement. On the
other hand, if Sterling is not able to pursue transactions that it otherwise believes are attractive, its competitive position may be harmed.

Acquisitions present many risks, and we may not realize the financial and strategic goals that are contemplated at the time of any
future acquisitions.

If the proposed Recapitalization Transactions are completed, our strategy will be to acquire
other banks in FDIC-assisted transactions or otherwise. This strategy entails risk. Acquisitions and related transition and integration activities may disrupt our ongoing business and divert managements attention. In addition, an acquisition
may not further our corporate strategy as we expected, we may pay more than the acquired banks or assets are ultimately worth or we may not integrate an acquired bank or assets as successfully as we expected, which could adversely affect our
business, results of operations and financial condition. We may be adversely affected by liabilities or pre-existing contractual relationships that we assume and may also fail to anticipate or accurately estimate litigation or other exposure,
unfavorable accounting consequences, increases in taxes due or a loss of anticipated tax benefits. Other potential adverse consequences include higher than anticipated costs associated with the acquired bank or assets or integration activities. The
use of cash to pay for acquisitions may limit our use of cash for other potential activities, such as dividends. The use of equity securities to pay for acquisitions could significantly dilute existing shareholders. If we use debt to finance
acquisitions, we may significantly increase our expenses, leverage and debt service requirements. The occurrence of any of these risks could have a material adverse effect on our business, results of operations, financial condition or cash flows,
particularly in the case of a large acquisition or several concurrent acquisitions.

Resales of our Common Stock may be
impeded by our Shareholder Rights Plan and our plan to amend our Articles of Incorporation to prevent the acquisition of 5% or more of our shares and the disposition of shares by any person owning 5% or more of our shares.

On April 14, 2010, we adopted a Shareholder Rights Plan (the Rights Plan), which is described in our Form 8-K filed on
April 15, 2010. The purpose of the Rights Plan is to minimize the likelihood of an ownership change, which is described below, and thus protect our ability to use our net operating loss carry-forward and certain built-in losses to
offset future income. The Rights Plan provides an economic disincentive for any one person or group to become a Threshold Holder (as defined therein) and for any existing Threshold Holder to acquire more than a specified amount of additional shares,
and so may adversely affect your ability to resell our Common Stock and negatively affect the trading price of our Common Stock.

In addition, we intend to propose, at a future shareholders meeting, an amendment to our Articles of Incorporation that would
impose transfer restrictions on all of our Common Stock designed to prevent (a) any person from

acquiring ownership, for relevant tax purposes, of 5% or more of our shares and (b) the disposition of shares by any person that owns 5% or more of our shares, subject to certain exceptions.
If adopted, these may adversely affect your ability to resell our Common Stock by rendering any transactions in violation of this prohibition void ab initio.

If the proposed Recapitalization Transactions are completed, Sterling may suffer substantial losses due to its obligations under agreements with
new investors.

If the proposed Recapitalization Transactions are completed, Sterling will be obligated to indemnify THL for a broad
range of claims, including any inaccuracies or breaches of Sterlings representations and warranties and any losses arising out of or resulting from any legal, administrative or other proceedings arising out of the transactions and the terms of
the securities being offered. Sterling could also be subject to claims under agreements with other investors. Claims under these agreements could potentially result in significant losses for Sterling.

If the proposed Recapitalization Transactions are completed, THL will be a substantial holder of our Common Stock.

Upon completion of the proposed Recapitalization Transactions, THL will own approximately 24.9% of our outstanding Common Stock on an as-converted and
fully exercised basis (and assuming approval from Treasury to increase the size of THLs investment), and will have a representative on our board of directors. Accordingly, THL will have substantial influence over the election of directors to
our board and over corporate policy, including decisions to enter into mergers or other extraordinary transactions. In addition, as part of the negotiations for THLs Investment, THL requested, and our board of directors agreed to grant,
pre-emptive rights to maintain THLs fully diluted percentage ownership of our Common Stock in the event of certain issuances of securities by us. In pursuing its economic interests, THL may make decisions with respect to fundamental corporate
transactions which may be different than the decisions of other shareholders.

Our ability to use our deferred tax assets may be
materially impaired by the proposed Recapitalization Transactions or other capital transactions.

As of March 31, 2010, our net
deferred tax asset was approximately $303 million, which includes approximately $188 million of federal and state operating losses (NOLs). We currently have a valuation allowance of $303 million against this deferred tax asset. Our
ability to use our deferred tax assets to offset future taxable income will be limited if we experience an ownership change as defined in Section 382 of the Internal Revenue Code of 1986, as amended from time to time (the
Code). Although we do not expect that the proposed Recapitalization Transactions will result in an ownership change, after taking into account the effects of the proposed Recapitalization Transactions or any other capital transactions we
may enter into if the proposed Recapitalization Transactions are not completed, we expect to be close to the ownership change threshold.

In general, an ownership change will occur if there is a cumulative increase in our ownership by 5-percent shareholders (as defined in the
Code) that exceeds 50 percentage points over a rolling three-year period. A corporation that experiences an ownership change will generally be subject to an annual limitation on the use of its pre-ownership change deferred tax assets equal to the
equity value of the corporation immediately before the ownership change, multiplied by the long-term tax-exempt rate, which is currently 4.03% for ownership changes occurring in May 2010.

While we have taken measures to reduce the likelihood that future transactions in our stock will result in an ownership change, there can be no assurance
that an ownership change will not occur in the future. More specifically, while the Rights Plan described above provides an economic disincentive for any one person or group to become a Threshold Holder (as defined in the Rights Plan) and for any
existing Threshold Holder to acquire more than a specified amount of additional shares, there can be no assurance that the Rights Plan will deter a shareholder from increasing its ownership interests beyond the limits set by the Rights Plan. Such an
increase could adversely affect our ownership change calculations.



51

##### Table of Contents

STERLING FINANCIAL CORPORATION

PART II  Other Information



Our calculations regarding our current cumulative change and the likelihood of a future
ownership change are based on current law. Any change in applicable law may result in an ownership change.

We may be
deemed to be in default with regard to certain of our borrowing agreements as a result of the receipt of the SSB Consent Agreement and the Reserve Bank Agreement.

Certain borrowing agreements that we have entered into require Sterling to remain well capitalized under regulatory requirements. Under
the terms of the SSB Consent Agreement and the Reserve Bank Agreement, Sterling agreed to, among other things, a capital maintenance provision, which by definition, excluded Sterling from well capitalized status. As of December 31, 2009,
Sterling has been deemed to be undercapitalized, which may trigger an event of default with regard to its reverse repurchase agreements. A declaration of default by the counterparties to these agreements could result in the
counterparties requesting an early termination payment, which could subject Sterling to additional costs based on the fair value of the borrowings at the date of the early termination.

We could be materially adversely affected if we or any of our officers or directors fail to comply with bank and other laws and
regulations.

As a bank holding company, we are subject to extensive regulation by U.S. federal and state regulatory
agencies and face risks associated with investigations and proceedings by regulatory agencies, including those that we may believe to be immaterial. Like any corporation, we are also subject to risk arising from potential employee misconduct,
including non-compliance with our policies. Any interventions by authorities may result in adverse judgments, settlements, fines, penalties, injunctions, suspension or expulsion of our officers or directors from the banking industry or other relief.
In addition to the monetary consequences, these measures could, for example, impact our ability to engage in, or impose limitations on, certain of our businesses. The number of these investigations and proceedings, as well as the amount of penalties
and fines sought, has increased substantially in recent years with regard to many firms in the industry. Significant regulatory action against us or our officers or directors could materially adversely affect our business, financial condition or
results of operations or cause us significant reputational harm, which could seriously harm our business.
