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, 2008. 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.

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

In December 2007, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standard (FAS) FAS No. 141 (R),
Business Combinations (FAS No. 141 (R)). FAS No. 141 (R) establishes principles and requirements for how the acquirer: 1) recognizes and measures in its financial statements the identifiable assets
acquired, the liabilities assumed, and any non-controlling interest in the acquiree; 2) recognizes and measures the goodwill acquired in the business combination or a gain from a bargain purchase; 3) determines what information to disclose to enable
users of the financial statements to evaluate the nature and financial effects of the business combination. FAS No. 141 (R) applies prospectively to business combinations entered into by Sterling after January 1, 2009. Depending
on the level of future acquisitions, FAS No. 141 (R) may have a material effect on Sterling, mainly in regards to the valuation of loans, and the treatment for acquisition costs.

In February 2008, the FASB issued FASB Staff Position (FSP) FAS 140-3, Accounting for Transfers of Financial Assets and Repurchase Financing
Transactions (FSP FAS No. 140-3). The FSP provides implementation guidance for linked transactions under FAS 140. The FSP states that a transferor and transferee shall not separately account for a transfer of a financial asset
and a related repurchase financing unless (a) the two transactions have a valid and distinct business or economic purpose for being entered into separately and (b) the repurchase financing does not result in the initial transferor
regaining control over the financial asset. This FSP was effective for Sterling as of January 1, 2009, and did not have a material impact on its consolidated financial statements.

In March 2008, the FASB issued FAS 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FAS 133. FAS 161 requires enhanced disclosures about how and why an entity uses
derivative instruments, how derivative instruments and related hedged items are accounted for under FAS 133 and related interpretations, and how derivative instruments and related hedged items affect an entitys financial position, financial
performance, and cash flows. FAS 161 was effective for Sterling as of January 1, 2009, and did not have a material effect on its consolidated financial statements.

In June 2008, the FASB issued FSP EITF 03-06-1, Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities. FSP EITF 03-06-1 requires all outstanding
unvested share-based payment awards that contain rights to non-forfeitable dividends to be considered participating securities and requires entities to apply the two-class method of computing basic and diluted earnings per share. This FSP was
effective for Sterling as of January 1, 2009, and did not have a material impact on its consolidated financial statements.

##### Table of Contents

In April 2009, the FASB issued FSP FAS 115-2 and 124-2, Recognition and Presentation of Other-Than-Temporary
Impairment (OTTI), FSP FAS 157-4, Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly, and FSP FAS 107-1
and APB 28-1, Interim Disclosures about Fair Value of Financial Instruments. For debt securities, the guidance differentiates credit driven and market driven OTTI. Only the portion of the impairment loss representing credit losses would
be recognized in earnings as an OTTI. The balance of the impairment loss would be recognized as a charge to other comprehensive income. A non-credit related OTTI charge to other comprehensive income for securities classified as held to maturity will
be amortized from accumulated other comprehensive income back to the security over the securities remaining life. Financial statement presentation will require segregation of accumulated comprehensive income for non-credit OTTI charges on held to
maturity and available for sale securities from other components of accumulated comprehensive income. The standard provided additional guidance for the determination of whether a market for an asset is not active and when a price for a transaction
is not distressed. The disclosure requirements of FAS 107 have been extended to interim periods. This guidance is effective for Sterling as of June 30, 2009. The company is currently evaluating the impact of these standards.

The increase in the provision stems from higher levels of classified assets and higher loss rates. Classified assets
include non-performing loans and OREO. The following is a summary of loans that are not performing in accordance with their original contractual terms:

Cumulatively, Sterling has written down its non-performing assets by $244.0 million as of March 31, 2009,
compared with write-downs of $207.7 million as of December 31, 2008 and $4.2 million as of March 31, 2008. At March 31, 2009, non-performing assets include $46.7 million of restructured loans that are performing in accordance
with their new terms and are accruing interest, compared with $29.5 million as of December 31, 2008, and none as of March 31, 2008.

As of
March 31, 2009, the allowance for losses on OREO totaled $17.0 million. Changes in this allowance are as follows for the periods presented:

3. Goodwill and Other Intangible Assets:

As of March 31, 2009 and December 31, 2008, Sterling had goodwill and other intangible assets totaling $253.1 million and $254.3 million, respectively.
Goodwill represents the difference between the value of consideration paid and the fair value of the net assets received in a business combination. Other intangible assets represent acquired customer depository relationships. Intangible assets are
periodically assessed for impairment. Sterlings management performed an annual test of its goodwill and other intangible assets as of June 30, 2008, and concluded that the recorded values were not impaired, based on present value
discounted cash flow analysis as allowed by FAS 142, Goodwill and Other Intangibles (FAS 142). During the fourth quarter of 2008, due to reduced expectations for near term profitability, and the protracted decline in
Sterlings stock price and market capitalization, Sterling determined that an impairment had occurred, and wrote off $223.8 million of its goodwill, following deterioration in its loan portfolio from worsening economic conditions,
continued stress on real estate values, increasing levels of both classified and non-performing assets and higher net charge-offs, that resulted in higher credit costs and lower earnings. Dividends on Sterlings newly issued preferred stock
also reduced income available to common shareholders. As of March 31, 2009, Sterling evaluated whether events or circumstances had occurred since its most recent impairment test that would be considered triggering events under FAS 142, thus
requiring an update to its goodwill impairment test. Sterling determined that no such events had occurred. There are many assumptions and estimates underlying the determination of whether goodwill has been impaired. Future events could cause
management to conclude that Sterlings goodwill or other intangible assets have become further impaired, which would result in Sterling recording an additional impairment loss.

Sterling raises capital from time to time 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. Interest is
paid quarterly or semiannually.

Details of the Trust Preferred Securities are as follows:

FSP EITF 03-06-1 proscribes a two-class method for entities that have participating securities such as
Sterlings unvested restricted shares that provide the holder of the shares with the right to receive any dividends issued by Sterling. Sterling applied the treasury stock method because it was the most dilutive method of measuring earnings per
share.

At March 31, 2009, the weighted average remaining contractual life and the aggregate intrinsic value of stock
options outstanding was 4.5 years and ($37.5) million, respectively, and of stock options exercisable was 4.2 years and ($29.7) million, respectively, and at December 31, 2008, was 4.3 years and ($26.9) million,
respectively, and 4.0 years and ($19.2) million, respectively. As of March 31, 2009, a total of 1,323,785 shares remained available for grant under Sterlings 2001, 2003 and 2007 Long-Term Incentive Plans. The stock options granted
under these plans have terms of four, six, eight or ten years. The stock options and restricted shares granted during 2009 have vesting schedules ranging from two to four years. During the three months ended March 31, 2009 and 2008, the
intrinsic value of options exercised were $0 and $2.2 million, respectively, and fair value of options granted were $192,000 and $1.1 million, respectively. The Black-Scholes option-pricing model was used in estimating the fair value of option
grants. The weighted average assumptions used were:

As of March 31, 2009, unrecognized equity compensation expense totaled $6.7 million, as the underlying
outstanding awards had not yet been earned. This amount will be recognized over a weighted average period of 2.4 years. During 2009, no stock options were forfeited. Any increase in forfeitures would lower the amount of future equity
compensation expense to be recognized.

9. 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, 2009, Sterling
had $188.8 million of interest rate lock commitments, $84.4 million of warehouse loans held for sale that were not committed to investors, and held offsetting forward sale agreements on MBS valued at $225.0 million. In addition Sterling had
mandatory delivery commitments to sell mortgage loans to investors valued at $20.9 million as of March 31, 2009. As of December 31, 2008, Sterling had $75.4 million of interest rate lock commitments, $71.8 million of warehouse loans
held for sale that were not committed to investors, and held offsetting forward sale agreements on MBS valued at $114.4 million. In addition, Sterling had mandatory delivery commitments to sell mortgage loans to investors valued at $1.4 million as
of December 31, 2008. As of March 31, 2009 and December 31, 2008, Sterling had entered into best efforts forward commitments to sell $119.6 million and $71.0 million of mortgage loans, respectively.

Sterling enters into interest rate swap derivative contracts with customers. The interest rate risk on these contracts is offset by entering into comparable broker
dealer swaps. These contracts are carried as an offsetting asset and liability at fair value, and as of March 31, 2009 and December 31, 2008, were $7.0 million and $7.5 million, respectively.

10. Fair Value:

FAS 159, The Fair Value Option for
Financial Assets and Financial Liabilities, gives companies the option of carrying financial assets and liabilities at fair value and can be implemented on all or individually selected financial instruments. Effective January 1, 2008,
Sterling elected to apply FAS 159 on newly originated loans held for sale under mandatory delivery programs. After analyzing the effects of FAS 159 on held for sale loans, Sterling elected to apply FAS 159 to all newly originated held for sale loans
effective April 1, 2008. 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. There was no transition adjustment upon adoption.

The framework for defining and measuring
fair value under FAS 157, Fair Value Measurements, 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 only be used when Level 1 and Level 2 inputs are unavailable.

Investments and mortgage-backed securities have been valued using a matrix pricing technique based on quoted
prices for similar instruments, while loans held for sale have been valued using investor quoted pricing inputs. Level 2 derivatives represent mortgage banking interest rate lock and loan delivery commitments, while level 3 derivatives represent
interest rate swaps. See Note 9 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 under FAS 159 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 following table presents the carrying value
for these financial assets as of the dates indicated:

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. The goodwill impairment resulted from a protracted decline in
Sterlings stock price and market capitalization. It also reflects the expectation for reduced near-term profitability because of higher credit costs and incorporates anticipation of lower net income available to common shareholders after the
payment of dividends on Sterlings preferred stock.

PART I  Financial Information (continued)

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

STERLING FINANCIAL CORPORATION

March 31, 2009

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 2008 annual report on Form 10-K.

General

Sterling Financial Corporation (Sterling) is a bank holding company, organized under the laws of Washington in 1992. The principal operating subsidiaries of
Sterling are Sterling Savings Bank and Golf Savings Bank. The principal operating subsidiary of Sterling Savings Bank is INTERVEST-Mortgage Investment Company (INTERVEST). Sterling Savings Bank commenced operations in 1983 as a
Washington State-chartered federally insured stock savings and loan association headquartered in Spokane, Washington. On July 8, 2005, Sterling Savings Bank converted to a commercial bank. 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 provides personalized,
quality financial services and Perfect Fit banking products to its customers consistent with its Hometown Helpful philosophy. Sterling believes that its 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 $12.82 billion in total assets as of March 31, 2009, Sterling originates loans and attracts Federal Deposit Insurance Corporation
(FDIC) insured deposits from the general public through 179 depository banking offices located in Washington, Oregon, California, Idaho and Montana. In addition, Sterling originates loans through Golf Savings Bank and Sterling Savings
Bank residential loan production offices, and through INTERVEST commercial real estate lending offices throughout the western United States. Sterling also markets fixed income and equity products, mutual funds, fixed and variable annuities and other
financial products through wealth management representatives located throughout Sterlings financial service center network.

Sterling continues to
implement its strategy to become the leading community bank in the western United States by increasing its commercial and consumer customer relationships that can provide a wider variety of lending opportunities, as well as increasing its commercial
and retail deposits, particularly transaction accounts. Management believes that a community bank mix of assets and liabilities will enhance its net interest income (the difference between the interest earned on loans and investments and the
interest paid on deposits and borrowings) and will increase other fee income, although there can be no assurance in this regard. Sterlings revenues are derived primarily from interest earned on loans and mortgage-backed securities
(MBS), fees and service charges, and mortgage banking operations. The operations of Sterling, and banking institutions generally, are influenced significantly by general economic conditions and by policies of its primary regulatory
authorities, the Board of Governors of the Federal Reserve System (the Federal Reserve), the FDIC and the Washington State Department of Financial Institutions.

Executive Summary and Highlights

Sterlings earnings per share and performance ratios continue to be impacted by the economic downturn which has led to higher credit costs as the result of ongoing asset quality concerns surrounding the levels of
both classified and non-performing assets, and higher net charge-offs. During the first quarter of 2009, Sterling recorded a $65.9 million provision for credit losses, compared to a $37.1 million provision for credit losses recorded during the
first quarter of 2008. Revenues, as defined by net interest income plus non-interest income, were up 6% year over year. Income from mortgage banking operations was up 115% from a year ago, reflecting lower prevailing interest rates and new lending
initiatives, which led to a significant increase in the volume of residential mortgage originations. Also reflecting the drop in interest rates, Sterling realized $10.6 million of net gains on the sales of securities. The year over year decrease of
4% in Sterlings net interest income primarily reflects a reduction in Sterlings net interest margin on a tax equivalent basis of 26 basis points to 2.98% from 3.24%. Sterlings higher level of non-performing assets (including
non-accrual loans and other real estate owned (OREO)), and its asset sensitivity, during a declining interest rate environment, contributed to the decrease in net interest margin.

First quarter 2009 highlights were as follows:



| |  |  | Total deposits increased 8% from a year ago to a record $8.49 billion.
| | - |  | ----------------------------------------------------------------------



| |  |  | Net interest margin improved to 2.98% from 2.80% for the December 31, 2008 quarter.
| | - |  | -----------------------------------------------------------------------------------



| |  |  | Income from mortgage banking operations rose 115% year over year.
| | - |  | -----------------------------------------------------------------



| |  |  | All capital ratios remain above well-capitalized levels.
| | - |  | ----------------------------------------------------------



| |  |  | Total assets were $12.82 billion.
| | - |  | ---------------------------------



| |  |  | Total loans receivable were $8.68 billion.
| | - |  | ------------------------------------------



| |  |  | Sterling expanded lending initiatives to benefit consumers and businesses.

Company Growth

Sterling intends to continue to pursue a long-term growth strategy to become the leading community
bank in the western United States, although, with the current economic slow down, growth opportunities are expected to be limited in the near-term and Sterling is considering various strategies to manage its capital and liquidity levels. In addition
to focusing on organic growth, Sterlings long term strategy may include acquiring other financial businesses or branches thereof, or other substantial assets or deposit liabilities. However, market conditions are having a significant negative
impact on the banking industry and there is no assurance that Sterling will be successful in completing any such acquisitions or achieving additional growth in the near term.

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 on a loan has become doubtful, which generally occurs when the loan is 90 days past due, Sterling discontinues the



18

##### Table of Contents

accrual of interest and any previously accrued interest recognized in income deemed uncollectible is reversed. Interest received on non-performing loans is
included in income only if principal recovery is reasonably assured. A non-performing loan is restored to accrual status when it is brought current, has performed in accordance with contractual terms for a reasonable period of time, 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 composed 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 non-performing loans, historical loan loss experience, 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.

During the fourth quarter of 2008, Sterling modified its estimate of the fair value of loans being tested for
impairment. The fair value is now estimated excluding the potential cash flows from certain guarantors. To the extent that these guarantors are able to provide repayments, a recovery would be recorded upon receipt. In addition, Sterling re-assessed
the accounting for real estate loans treated as collateral dependent. As a result, Sterling now considers any impairment on a collateral-dependent loan to be a confirmed loss and charges off the impairment amount when the impairment is identified,
rather than establishing a specific allowance on impaired collateral-dependent loans that would have been charged off when foreclosure was probable.

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, trends in losses and delinquencies, growth of
loans in particular markets, and known changes in economic conditions in each particular lending market.

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 slowdown in
economic activity could continue to adversely affect cash flows for both commercial and individual borrowers, as a result of which Sterling could experience further increases in non-performing 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, 2009.

Investment Securities and MBS.Assets in the investment securities 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. Municipal bonds that Sterling holds are all general obligation in nature, 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. 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.

##### Table of Contents

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, 2009, 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 one single-issuer trust preferred security, and 19 private label collateralized mortgage obligations. The trust preferred security is rated A1 by Moodys and has an amortized cost of
$24.6 million compared to a $10.6 million market value, or an unrealized loss of $14.0 million. As of March 31, 2009, the private label collateralized mortgage obligations had an amortized cost of $265.1 million compared to a $207.8 million
market value, or an unrealized loss of $57.3 million. Their current ratings are: $122 million AAA- by S&P and Aaa- by Moodys; $16 million AAA by S&P and A3 by Moodys; $31 million AAA- by S&P and AA- by Fitch; with balance
rated AAA by S&P and Aaa by Moodys. All of the aforementioned positions remain investment grade, and all are stress-tested monthly for both credit quality and collateral strength. As of March 31, 2009, Sterling expects the return of
all principal and interest on all securities within the portfolios pursuant to the contractual terms and Sterling has the ability and intent to hold these investments until 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. See   New Accounting
Pronouncements.

Fair Value of Financial Instruments. Sterlings available-for-sale securities portfolio totaled $2.73 billion and
$2.64 billion as of March 31, 2009 and December 31, 2008, respectively, and were the most substantial 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.

Loans held for sale are also carried at fair value, as Sterling has applied FAS 159 to these loans 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.

Goodwill and Other Intangible Assets.Goodwill arising from business combinations represents the value attributable to unidentifiable intangible elements in the business acquired. Sterlings goodwill relates to
value inherent in the banking business and the value is dependent upon Sterlings ability to provide quality, cost effective services in a competitive market place. As such, goodwill value is supported ultimately by revenue that is generated by
the volume of business transacted.

Sterlings management performed an annual test of its goodwill and other intangible assets as of June 30,
2008, and concluded that the recorded values were not impaired, based on present value discounted cash flow analysis as allowed by FAS 142, Goodwill and Other Intangibles (FAS 142). During the fourth quarter of 2008, due to
reduced expectations for near term profitability, and the protracted decline in Sterlings stock price and market capitalization, Sterling determined that an impairment had occurred, and wrote off $223.8 million of its goodwill, following
deterioration in its loan portfolio from worsening economic conditions, continued stress on real estate values, increasing levels of both classified and non-performing assets and higher net charge-offs, resulted in higher credit costs and lower
earnings. Dividends on Sterlings newly issued preferred stock also reduce income available to common shareholders. As of March 31, 2009, Sterling evaluated whether events or circumstances had occurred since its most recent impairment test
that would be considered triggering events under FAS 142, thus requiring an update to its goodwill impairment test. Sterling determined that no such events had occurred. There are many



20

##### Table of Contents

assumptions and estimates underlying the determination of whether goodwill has been impaired. Future events could cause management to conclude that
Sterlings goodwill or other intangible assets have become further impaired, which would result in Sterling recording an additional impairment loss. Other intangible assets consisting of core deposit intangibles with definite lives are
amortized on a straight line basis over the estimated life of the acquired depositor relationships (generally eight to ten years).

Loan
Purchases. In accordance with the American Institute of Certified Public Accountants Statement of Position (SOP) 03-3, Accounting for Certain Loans or Debt Securities Acquired in a Transfer, loans are recorded
at fair value if, when they are acquired, they show evidence of deterioration in terms of credit quality, and a loss is deemed likely to occur. Fair value is defined as the present value of future cash flows, including interest income, to be
recognized over the life of the loan. SOP 03-3 prohibits the carryover of an allowance for loan loss on certain acquired loans within its scope that are considered in the future cash flow assessment. Sterling applies this guidance when entering into
applicable transactions.

Other Real Estate Owned. Property and other assets acquired through foreclosure of defaulted mortgage or other
collateralized loans are carried at the lower of cost or fair value, less estimated selling costs. The fair value of OREO is generally determined from appraisals obtained by independent appraisers. Development and improvement costs relating to such
property are capitalized to the extent they are deemed to be recoverable.

An allowance for losses on OREO includes amounts for estimated losses as a
result of impairment in value of the property after repossession. Sterling reviews its OREO for impairment in value whenever events or circumstances indicate that the carrying value of the property or other assets may not be recoverable. In
performing the review, if expected future undiscounted cash flow from the use of the property or other assets, or the fair value, less selling costs, from the disposition of the property or other assets is less than its carrying value, an impairment
loss is recognized.

Loans Held for Sale. The majority of loans held for sale are carried at fair value, as Sterling has applied FAS 159 to
most of these loans 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. A small portion of Sterlings held for sale portfolio is reported at
the lower of amortized cost or market value, as the fair value of certain loan types cannot be efficiently estimated. Any loan that management determines will not be held to maturity is classified as held for sale. Loan origination fees, costs and
servicing rights are recognized as part of the loan value at origination. The fair value of loans held for sale is determined based upon an analysis of investor quoted pricing inputs. This value is based on quoted prices for similar instruments in
both active and inactive markets, therefore, these loans are classified as level 2.

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 to support its position that the benefit of its net deferred tax assets will be realized. If future taxable income should prove non-existent or less than the amount of temporary differences
giving rise to the net deferred tax assets within the tax years to which they may be applied, the assets will not be realized and Sterlings net income will be reduced. As of March 31, 2009 Sterling believes that it is more likely than not
that it will be able to fully realize its deferred tax asset and therefore has not recorded a valuation allowance.

Results of Operations

Overview. Sterling reported a net loss of $20.4 million for the first quarter ended March 31, 2009, reflecting a provision for credit losses of $65.9 million, but not including the payment of $4.3 million in
preferred dividends to the U.S. Department of the Treasury under its Capital Purchase Program. After the payment of preferred dividends, earnings available to common shareholders were a negative $24.8 million, or $0.48 per diluted share.
Earnings for the first quarter ended March 31, 2008, were $2.9 million, or $0.06 per common share, and reflected a provision for credit losses of $37.1 million. The annualized return on average assets was -0.65% and 0.09% for the three months
ended March 31, 2009 and 2008, respectively. The annualized return on average common equity was -11.9% and 1.0% for the three months ended March 31, 2009 and 2008, respectively. The year over year decrease in net income and performance
ratios primarily reflected an increased credit provision in response to an increase in the level of classified assets and higher loss rates.

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, 2009 and 2008, net interest income was $88.3 million and $92.1 million, respectively, a decrease of 4%. The decrease in net interest income
during the three month comparative period was primarily due to the increase in non-performing assets, including non-performing loans and OREO.

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 non-performing
assets, and the decline in the prime rate. Sterling has been asset sensitive during recent periods, with a higher level of interest earning assets that were subject to re-pricing faster in the short term than deposits and borrowings.
Additionally, when loans reach non-performing status, the reversal and cessation of accruing interest has an immediate negative impact on net interest margin.

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 and trends in classified assets, delinquency and non-accrual loans, and portfolio volume, diversification as to
type of loan, size of individual credit exposure, current and anticipated economic conditions, as well as 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 losses on loans of $65.9 million and $37.1 million for the
three months ended March 31, 2009 and 2008, respectively. Sterling has increased its provision for credit losses in response to an increase in the level of classified loans, particularly in the construction portfolio, and increases in loss
rates due to reduced appraisal values.

The following table summarizes the allowance for credit losses for the periods indicated:

Sterling modified its methodology for estimating the fair value of loans being tested for impairment during the
fourth quarter of 2008. The fair value is now determined excluding the potential cash flows from certain guarantors. To the extent that these guarantors are able to provide repayments, a recovery would be recorded upon receipt. In addition to the
higher credit provision recorded during the fourth quarter of 2008, in many cases, Sterling

re-assessed the accounting for real estate loans treated as collateral dependent. As a result, Sterling now considers any impairment on a
collateral-dependent loan to be a confirmed loss and charges off the impairment amount when the impairment is identified, rather than establishing a specific allowance on impaired collateral-dependent loans that would have been charged off when
foreclosure was probable.

Non-performing assets, a subset of classified assets that includes non-performing loans and OREO, were 5.23% of total assets at
March 31, 2009, compared with 1.76% of total assets at March 31, 2008. At March 31, 2009, the delinquency ratio for loans 60 days or more past due was 5.24% of total loans compared to 2.38% of total loans at March 31, 2008.
Sterling, like many other financial institutions, has experienced deterioration in the credit quality of residential construction loans and increases in delinquencies due to declining market values and weakness in housing sales in certain of its
markets.

At March 31, 2009, Sterlings total classified assets were 8.35% of total assets, compared with 3.17% of total assets at March 31,
2008. The following table describes classified assets by asset type as of the dates indicated:

The linked-quarter growth of non-performing assets represented a deceleration in the rate of quarterly growth,
which had ranged between 36% and 65% over the previous four quarters. Sterling believes that the slowing growth rates of classified and non-performing assets, mainly related to construction, reflects the cumulative efforts of its construction credit
team, which has been in place for more than one year, to identify, manage and resolve stressed assets. The process of resolving problem assets involves restructuring loans, obtaining additional collateral, repossessing problem assets and evaluating
loans in relation to fair market value.

Cumulatively, Sterling has written down its non-performing assets by $244.0 million as of March 31, 2009, compared
with write-downs of $207.7 million as of December 31, 2008 and $4.2 million as of March 31, 2008. OREO, net of allowances, was $83.6 million at quarter end, compared with $62.3 million in the linked quarter, and $13.0 million in
the year-ago quarter. OREO is included in non-performing assets. Weakness in the overall economy has contributed to increased levels of nonperforming assets in the construction, commercial banking, commercial real estate and non-owner occupied
residential portfolios.

In the first quarter of 2009, non-interest income rose 52% to $32.1 million from $21.2 million in the first
quarter of 2008. The increase in non-interest income was driven by higher levels of income from mortgage banking operations and gains on the sales of securities. Mortgage banking operations income in the first quarter of 2009 rose 115% over the
first quarter of 2008, continuing the trend that started in the fourth quarter of 2008. The mortgage banking segment growth in originations and revenues was driven by lower interest rates and programs designed to spur lending consistent with the
U.S. Department of the Treasurys Capital Purchase Program. Favorable market conditions provided the opportunity to realize gains within the securities portfolio during 2009. Fees and service charges income continues to reflect higher analyzed
account fees, loan-related fees and transaction fees, offset by a decrease in fees related to Sterlings Balance Shield Program, where the decrease in the volume of overdraft incidents more than offset account growth, and lower commissions from
Sterlings Wealth Management group. At quarter end, the total number of transaction accounts exceeded 200,000, an increase of 2% year over year. The elevation in OREO expenses during the first quarter of 2009 reflects a decline in asset values
subsequent to acquisition, as well as write-downs to align valuations with pending OREO sales. Other non-interest income for the three months ended March 31, 2009 includes a $1.1 million loss, which represents Sterlings prorata share of a
public funds loss resulting from the failure of a Washington state public depository bank.

Non-interest expenses rose 5% to $75.5 million in the first quarter of 2009 from $72.1 million in the first
quarter of 2008. Excluding FDIC deposit insurance premiums, which rose by $2.5 million, non-interest expenses for the quarter ended March 31, 2009 increased only 1% year over year despite overall company growth. The small increase in
non-interest expenses reflects improved operating efficiencies and tight cost controls. During the quarter, Sterling began realizing the benefits of systemic process improvements relating to the closure of two item processing centers following the
complete rollout of the remote teller capture system. On a year over year basis, the number of full-time equivalent employees decreased by 39 to 2,518.

Income Tax Provision. Sterling recorded a federal and state income tax benefit of $436,000 for the three months ended March 31, 2009, and a provision of $1.1 million for the three months ended March 31, 2008.
The effective tax rates for these periods were 2% and 28%, respectively. The elevated level of loan loss provisions has increased the proportional effect of tax credits and tax exempt income, resulting in the decrease in the effective tax rate. As
of March 31, 2009, Sterling believes that it is more likely than not that it will be able to fully realize its deferred tax asset and therefore has not recorded a valuation allowance.

Financial Position

Assets. At March 31, 2009, Sterlings assets were $12.82 billion, up $28.9 million from $12.79 billion at December 31, 2008. This growth was mainly a result of increases from securities purchases
and a longer retention period on held-for-sale loans outweighing decreases in the loan portfolio and the collection of a $39.0 million federal tax refund.

Investment Securities and MBS. Sterlings investment and MBS portfolio at March 31, 2009 was $2.91 billion, an increase of $93.2 million from the December 31, 2008 balance of $2.82
billion. The increase was due to purchases exceeding principal repayments, maturities and sales. On March 31, 2009, the investment and MBS portfolio had an unrealized loss of $21.9 million versus an unrealized loss of $28.4 million at
December 31, 2008.

Loans Receivable. At March 31, 2009, net loans receivable were $8.68 billion, compared to $8.81 billion
at December 31, 2008, and $9.12 billion at March 31, 2008. The contraction in Sterlings loan portfolio reflects Sterlings goal of reducing construction loans as a percent of its total loan portfolio, and a lessening of demand
for credit in a slowing economy. At the end of the first quarter of 2009, residential construction loans represented 15% of Sterlings loan portfolio, compared with 21% at the end of the first quarter of 2008. Over the last year, residential
construction loans decreased by $611.5 million to $1.33 billion at March 31, 2009.

The following table sets forth the composition of Sterlings
loan portfolio as of the dates indicated. Loan balances exclude deferred loan origination costs and fees, and allowances for loan losses:

Stimulated by historically low mortgage rates and new initiatives to provide affordable housing, residential
mortgage originations climbed 73% from the year-ago period. The decrease in construction loan originations, reflects Sterlings goal of reducing construction loans as a percent of its total loan portfolio. Loan originations relative to the
fourth quarter of 2008 rose 35%. This sequential increase reflects Sterlings effort, since December 2008, to expand and enhance lending initiatives to support and restore economic growth and development in the communities it serves with
capital raised through the U.S. Department of the Treasurys Capital Purchase Program. Sterlings new lending initiatives focus on funding affordable housing, small business loans and financing programs to support business growth.

Deposits. The following table sets forth the composition of Sterlings deposits at the dates indicated:

During the quarter, there was a shift of uninsured savings and money market account balances to FDIC insured
interest bearing transaction accounts. This was related to changes in the collateralization requirements associated with uninsured public funds deposits and Sterlings participation in the FDIC voluntary expanded insurance program, which
provides, without charge to depositors, full guarantee on non-interest bearing and certain interest-bearing transaction accounts held by any depositor, regardless of dollar amount.

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 asset growth and meet deposit withdrawal requirements. During the three months ended March 31, 2009, these funding sources decreased a total of $93.8 million, with maturing advances from the FHLB
being offset with growth in deposits and funds purchased from the Federal Reserves discount window.

Asset and Liability Management

The results of operations for financial institutions may be materially and adversely affected by changes in prevailing economic conditions, including rapid 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.

Sterlings subsidiary banks Asset/Liability Committees (ALCO) manage their interest-rate risk based on interest rate expectations and other
factors within policies and practices approved by the subsidiary banks Boards of Directors. The principal objective of Sterlings subsidiary banks 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.

The difference between a financial institutions interest rate sensitive assets (i.e., assets that will mature or reprice within a
specific time period) and interest rate sensitive liabilities (i.e. liabilities that will mature or reprice within the specific time period) is commonly referred to as its 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. Sterling has been asset sensitive during
2008 and 2009, with a higher level of interest earning assets that were subject to re-pricing faster in the short term than deposits and borrowings.

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 100 and 200
basis points and down 100 basis points. 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 for the simulation. 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. Further, 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, 2009 and
December 31, 2008 are included in the following table:

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 100 and 200 basis points and down 100 basis points. 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, 2009 and December 31, 2008 are included in the following table:

Sterling occasionally enters into customer-related financial derivative transactions primarily consisting of
interest rate swaps. Risk exposure from customer positions is managed through transactions with other broker dealers. As of March 31, 2009, Sterling has not entered into asset/liability related derivative transactions as part of managing its
interest rate risk. However, Sterling continues to consider derivatives, including interest rate swaps, caps and floors, as a viable alternative in the asset and liability management process.

Liquidity and Capital Resources

Sterlings primary sources of funds are: customer deposits; wholesale funds 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 expected and potential loan fundings and deposit withdrawals. This is balanced with the need to
maximize yield on alternative investments. The liquidity ratio may vary from time to time, depending on economic conditions, deposit fluctuations and loan funding needs.

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 credits and term auction facilities from the Federal Reserve, and federal funds purchased. Sterling had access to $3.08 billion and $3.23 billion of additional liquidity from these sources as of March 31,
2009 and December 31, 2008, respectively. In 2009, certain states have either increased or proposed to increase the collateralization requirements for uninsured public funds. The increased collateralization requirements would require that
Sterling pledge additional collateral, which would reduce Sterlings collateral available for liquidity. Alternately Sterling could choose to reduce the amount of public deposits accepted in those states to reduce the risk associated with the
states collateral pools. 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, 2009 and December 31, 2008, these credit lines represented a total borrowing capacity of $2.49 billion and $2.92 billion, of which $1.05 billion and $1.33 million was available, respectively. At March 31, 2009 and
December 31, 2008, Sterling had $1.04 billion and $1.09 billion in outstanding borrowings under reverse repurchase agreements, respectively. Sterling had securities available for additional secured borrowings of approximately
$809.2 million and $513.7 million as of March 31, 2009 and December 31, 2008, 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. Sterling also had $179.2 million and $69.0 million of federal funds
purchased and discount window borrowings, which are short term borrowings from correspondent banks and the Federal Reserve, as of March 31, 2009 and December 31, 2008, respectively. Through the Federal Reserves 12th District Bank,
Sterling participates in the Borrower in Custody Program (BIC) which allows Sterling to borrow against certain pledged loans for terms ranging from overnight to 90 days. Sterling is also eligible to participate in the Term Auction
Facility (TAF) which allows Sterling to bid on funds to be borrowed for terms of 28 to 84 days.

On December 5, 2008, Sterling completed
the sale of 303,000 shares of preferred stock and issued a warrant to purchase 6,437,677 shares of Sterlings common stock to the U.S. Department of the Treasury, raising total proceeds of $303 million. The $303 million in proceeds are
treated as Tier 1 capital. The 303,000 shares of Fixed Rate Cumulative Perpetual Preferred Stock, Series A (the Preferred Shares), issued by Sterling will pay a cumulative compounding dividend of 5% per year for the first five years
and will reset to a rate of 9% per year after five years. After three years, the Preferred Shares may be redeemed by Sterling at their issue price, plus all accrued and unpaid dividends. Subject to approval by Sterlings banking
regulators, the Preferred Shares may also be redeemed at any time if Sterling chooses to replace them with newly raised equity capital. In addition to the Preferred Shares, the Treasury Department received a warrant to purchase 6,437,677 shares of
Sterling common stock at an exercise price of $7.06 per share.

Notwithstanding the foregoing, the American Recovery and Reinvestment Act of 2009
(ARRA), which was signed into law on February 17, 2009, provides that the Secretary of the Treasury shall permit, subject to consultation with the recipients appropriate Federal banking agency, a recipient of funds under the
Troubled Assets



32



---

##### Table of Contents

Relief Program (TARP) to repay the funds previously provided under the TARP, without regard to whether the recipient has replaced such funds from
any other source or to any waiting period. ARRA further provides that when the recipient repays the TARP funds, the Secretary of the Treasury shall liquidate the warrants associated with the funds at the current market price. Although the Treasury
Department has not yet issued any regulations or any other guidance, as of the date of this report, as to how this new provision of the ARRA will be implemented, it appears that ARRA will permit Sterling, if it so elects and following consultation
with the FDIC, to redeem the Preferred Shares at any time without restriction.

Sterling, on a parent company-only basis, had cash of approximately
$64.4 million and $86.2 million at March 31, 2009 and December 31, 2008, respectively. Sterlings total investment in Sterling Saving Bank as of March 31, 2009 was $1.27 billion compared to $1.02 billion as of
December 31, 2008. The increase was due to Sterling purchasing $25.0 million of Sterling Savings Bank preferred stock during the first quarter of 2009. Sterlings investment in Sterling Savings Bank consisted of $865.8 million of common
stock and $408.1 million of preferred stock as of March 31, 2009 and $865.8 million of common stock and $383.1 million of preferred stock as of December 31, 2008. Sterlings total investment in Golf Savings Bank was $60.7 million,
including $35.7 million of common stock and $25.0 million of preferred stock, as of both March 31, 2009 and December 31, 2008. Sterling received cash dividends from Sterling Savings Bank of $6.4 million and $9.3 million during the
three months ended March 31, 2009 and 2008, respectively, and from Golf Savings Bank of $240,000 and $0 for the same respective periods. These resources contributed to Sterlings ability to meet its operating needs, including interest
expense on its long-term debt and the payment of dividends. Sterling Savings Banks and Golf Savings Banks ability to pay dividends is limited by their earnings, financial condition, capital requirements, and capital distribution
regulations.

Sterling has had the ability to secure additional capital through the capital markets. The availability and cost of such capital is partially
dependent on Sterlings credit ratings. In January 2009, in response to Sterlings announcement of increased non-performing assets and higher net charge-offs, Fitch Ratings placed Sterling and Sterling Savings Banks credit ratings on
a negative rating watch and downgraded its individual rating to C. There can be no assurance that Sterling will continue to be able to access the capital markets in the future.

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.

As of both March 31, 2009 and December 31, 2008, the
reserve for unfunded commitments was $21.3 million. 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.

##### Table of Contents

Interest rate lock commitments and loan delivery commitments are off balance sheet commitments that are considered to be
derivatives. As of March 31, 2009, Sterling had $188.8 million of interest rate lock commitments, $84.4 million of warehouse loans held for sale that were not committed to investors, and held offsetting forward sale agreements on MBS valued at
$225.0 million. In addition Sterling had mandatory delivery commitments to sell mortgage loans to investors valued at $20.9 million as of March 31, 2009. As of December 31, 2008, Sterling had $75.4 million of interest rate lock
commitments, $71.8 million of warehouse loans held for sale that were not committed to investors, and held offsetting forward sale agreements on MBS valued at $114.4 million. In addition, Sterling had mandatory delivery commitments to sell
mortgage loans to investors valued at $1.4 million as of December 31, 2008. As of March 31, 2009 and December 31, 2008, Sterling had entered into best efforts forward commitments to sell $119.6 million and $71.0 million of mortgage
loans, respectively.

Sterling enters into interest rate swap derivative contracts with customers. The interest rate risk on these contracts is offset by
entering into comparable broker dealer swaps. These contracts are carried as an offsetting asset and liability at fair value, and as of March 31, 2009 and December 31, 2008, were $7.0 million and $7.5 million, respectively.

Capital

Sterlings total shareholders
equity decreased $19.4 million to $1.12 billion during the three months ended March 31, 2009 from $1.14 billion at December 31, 2008, reflecting the net loss resulting from higher provisions for credit losses, and the preferred
stock dividend under the U.S. Department of the Treasury CPP Program.

At March 31, 2009 and December 31, 2008, Sterling had an unrealized loss
of $21.9 million and $28.4 million, respectively, on investment securities and MBS classified as available for sale. Fluctuations in prevailing interest rates and other market factors continue to cause volatility in this component of
accumulated comprehensive income or loss in shareholders equity and may continue to do so in future periods. Shareholders equity was 8.75% of total assets at March 31, 2009 compared with 8.92% at December 31, 2008.

Sterling has outstanding various series of capital securities (Trust Preferred Securities) issued to investors. The Trust Preferred Securities are treated
as debt of Sterling, and can qualify as Tier 1 capital, subject to certain limitations.

Sterling, Sterling Savings Bank and Golf Savings Bank are required by applicable regulations to maintain certain minimum
capital levels. Sterlings management intends to enhance the capital resources and regulatory capital ratios of Sterling and its banking subsidiaries through the retention of an adequate amount of earnings and the management of the level and
mix of assets, although there can be no assurance in this regard. At March 31, 2009, each of the companies exceeded all such regulatory capital requirements and were well capitalized pursuant to such regulations. The following table
sets forth their respective capital positions at March 31, 2009:

Goodwill Litigation

In the fourth quarter of 2008, following mediation, Sterling settled on the amount of damages owed to Sterling and fully resolved its goodwill lawsuit against the U.S. government for its breach of contract related to past acquisitions of
failed savings institutions. Sterling was paid $1.8 million in January 2009. Sterling is satisfied that it prevailed in the litigation, which now is fully concluded.

New Accounting Pronouncements

In December 2007, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standard (FAS) FAS No. 141 (R), Business Combinations (FAS No. 141 (R)). FAS No. 141 (R) establishes principles and requirements for how the acquirer:
1) recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any non-controlling interest in the acquiree; 2) recognizes and measures the goodwill acquired in the business combination or
a gain from a bargain purchase; 3) determines what information to disclose to enable users of the financial statements to evaluate the nature and financial effects of the business combination. FAS No. 141 (R) applies prospectively to
business combinations entered into by Sterling after January 1, 2009. Depending on the level of future acquisitions, FAS No. 141 (R) may have a material effect on Sterling, mainly in regards to the valuation of loans, and the
treatment for acquisition costs.

In February 2008, the FASB issued (FASB Staff Position) FSP FAS 140-3, Accounting for Transfers of
Financial Assets and Repurchase Financing Transactions (FSP FAS No. 140-3). The FSP provides implementation guidance for linked transactions under FAS 140. The FSP states that a transferor and transferee shall not separately
account for a transfer of a financial asset and a related repurchase financing unless (a) the two transactions have a valid and distinct business or economic purpose for being entered into separately and (b) the repurchase financing does
not result in the initial transferor regaining control over the financial asset. This FSP was effective for Sterling as of January 1, 2009, and did not have a material impact on its consolidated financial statements.

In March 2008, the FASB issued FAS 161, Disclosures about Derivative Instruments and Hedging Activities, an amendment of FAS 133. FAS 161 requires enhanced
disclosures about how and why an entity uses derivative instruments, how derivative instruments and related hedged items are accounted for under FAS 133 and related

interpretations, and how derivative instruments and related hedged items affect an entitys financial position, financial performance, and cash flows.
FAS 161 was effective for Sterling as of January 1, 2009, and did not have a material effect on its consolidated financial statements.

In June 2008,
the FASB issued FSP EITF 03-06-1, Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities. FSP EITF 03-06-1 requires all outstanding unvested share-based payment awards that
contain rights to non-forfeitable dividends to be considered participating securities and requires entities to apply the two-class method of computing basic and diluted earnings per share. This FSP was effective for Sterling as of January 1,
2009, and did not have a material impact on its consolidated financial statements.

In April 2009, the FASB issued FSP FAS 115-2 and 124-2,
Recognition and Presentation of Other-Than-Temporary Impairment (OTTI), FSP FAS 157-4, Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying
Transactions That Are Not Orderly, and FSP FAS 107-1 and APB 28-1, Interim Disclosures about Fair Value of Financial Instruments. For debt securities, the guidance differentiates credit driven and market driven OTTI. Only the
portion of the impairment loss representing credit losses would be recognized in earnings as an OTTI. The balance of the impairment loss would be recognized as a charge to other comprehensive income. A non-credit related OTTI charge to other
comprehensive income for securities classified as held to maturity will be amortized from accumulated other comprehensive income back to the security over the securities remaining life. Financial statement presentation will require segregation of
accumulated comprehensive income for non-credit OTTI charges on held to maturity and available for sale securities from other components of accumulated comprehensive income. The standard provided additional guidance for the determination of whether
a market for an asset is not active and when a price for a transaction is not distressed. The disclosure requirements of FAS 107 have been extended to interim periods. This guidance is effective for Sterling as of June 30, 2009. The company is
currently evaluating the impact of these standards.

Regulation and Compliance

Sterling is subject to many laws and regulations applicable to banking activities. As a bank holding company, Sterling is subject to comprehensive examination and regulation by the Federal Reserve. Sterling Savings
Bank, as a Washington State-chartered bank, and Golf Savings Bank, as a Washington State-chartered savings bank, are subject to comprehensive regulation and examination by the Washington Supervisor and the FDIC. Sterling Savings Bank and Golf
Savings Bank are further subject to Federal Reserve regulations related to deposit reserves and certain other matters.

On October 3, 2008, in
response to upheaval within the financial markets, the President signed into law the Emergency Economic Stabilization Act of 2008 (the EESA), which authorized the United States Department of Treasury (the Treasury Department)
to establish the Troubled Assets Relief Program (TARP) to purchase troubled assets held by financial institutions. Under the TARP program the Treasury Department is authorized to purchase, and to make and fund commitments to
purchase, troubled assets from any financial institution, on such terms and conditions as are determined by the Treasury Department. The purpose of this program is to restore confidence and stability to the financial markets and to encourage the
flow of credit within the financial system.

On October 14, 2008, the Treasury Department announced the terms of the TARP Capital Purchase Program
(CPP), through which the Treasury Department has made capital investments in banking institutions, including Sterling, by purchasing senior preferred shares. On December 5, 2008, in accordance with the CPP, Sterling completed the
sale of 303,000 shares of preferred stock and issued a warrant to purchase 6,437,677 shares of Sterlings common stock to the Treasury Department, raising total proceeds of $303 million.

In February 2009, the American Recovery and Reinvestment Act of 2009 (ARRA) was enacted, which contains a comprehensive set of government spending
initiatives and tax incentives aimed at stimulating the U.S. economy. The ARRA also amends, among other things, the TARP program legislation by directing the Treasury Department to issue regulations implementing strict limitations on the payment of
incentive compensation and any severance or golden parachute payments to certain highly compensated employees of institutions that participate in the CPP. The

ARRA also expands the scope of employees who are subject to a clawback of bonus and incentive compensation that is based on results that are later found to
be materially inaccurate, adds additional corporate governance requirements, and requires the Treasury Department to perform a retroactive review of compensation to the five highest compensated employees of all CPP participants.

EESA and ARRA followed, and have been followed by, numerous actions by the Federal Reserve, Congress, Treasury Department, the SEC and others to address the current
liquidity and credit crisis that has followed the sub-prime meltdown that commenced in 2007. These measures include homeowner relief that encourage loan restructuring and modification; the establishment of significant liquidity and credit facilities
for financial institutions and investment banks; the lowering of the federal funds rate, including two 50 basis point decreases in October of 2008; emergency action against short selling practices; a temporary guaranty program for money market
funds; the establishment of a commercial paper funding facility to provide back-stop liquidity to commercial paper issuers; and coordinated international efforts to address illiquidity and other weaknesses in the banking sector. It is not clear at
this time what impact the EESA, ARRA, the CPP, the TARP, other liquidity and funding initiatives of the Federal Reserve and other agencies that have been previously announced, and any additional programs that may be initiated in the future will have
on the financial markets, including the extreme levels of volatility and limited credit availability currently being experienced, or on the U.S. banking and financial industries and the broader U.S. and global economies. Further adverse effects
could have an adverse effect on Sterling and its business.

Sterling must pay applicable FDIC insurance premiums with respect to its deposits that are
eligible for FDIC insurance. After the passage of the EESA, the FDIC also increased deposit insurance for all deposit accounts up to $250,000 per account as of October 3, 2008 and ending December 31, 2009. Effective April 1, 2009, the
FDIC changed the way its assessment system differentiates for risk, making corresponding changes to assessment rates beginning with the second quarter of 2009, and made certain technical and other changes to these rules. The increase in deposit
insurance described above, as well as the recent increase and anticipated additional increase in the number of bank failures, is expected to result in an increase in deposit insurance assessments for all banks, including Sterling. The FDIC is
required by law to return the insurance reserve ratio to a 1.15 percent ratio no later than the end of 2013. As of December 31, 2008, that ratio was 0.40 percent.

As FDIC-insured depository institutions, our bank subsidiaries may be held liable for any loss incurred or expected to be incurred by the FDIC in connection with another FDIC-insured institution under common control
with the institution in default or in danger of default. This liability is commonly referred to as cross-guarantee liability. A default is generally defined as the appointment of a conservator or
receiver and in danger of default is defined as certain conditions indicating that a default is likely to occur absent regulatory assistance. An FDIC cross-guarantee claim against a depository institution is generally senior in right of
payment to claims of the holding company and its affiliates against the depository institution.

Forward-Looking Statements

From time to time, Sterling and its senior managers have made and will make forward-looking statements within the meaning of the Private Securities Litigation Reform Act
of 1995. 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 senior managers in oral or written presentations to
analysts, investors, the media and others. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. Also, forward-looking statements can generally be identified by words such as
may, could, should, would, believe, anticipate, estimate, seek, expect, intend, plan and similar expressions.

Forward-looking statements provide managements expectations or predictions of future conditions, events or results. They are not guarantees of
future performance. By their nature, forward-looking statements are subject to risks and uncertainties. These statements speak only as of the date they are made. Sterling does not undertake to update forward-looking statements to reflect the impact
of circumstances or events that arise after the date the forward-looking statements were made. There are a number of factors, many of which are beyond Sterlings control that could cause actual conditions, events or results to differ
significantly from those described in the forward-looking statements. These factors, some of which are discussed elsewhere in this report, include:

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

Changes in Internal Control Over Financial Reporting
