NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
Columbia Banking System, Inc.
1.
Basis of Presentation and Significant Accounting Policies
Basis of Presentation
The interim unaudited 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 instructions to Form 10-Q and Article 10 of Regulation S-X. The consolidated financial statements include the accounts of the Company, and its wholly owned banking subsidiary Columbia Bank (the “Bank”). All intercompany transactions and accounts have been eliminated in consolidation. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair statement of the results for the interim periods presented have been included. The results of operations for the three months ended March 31, 2013 are not necessarily indicative of results to be anticipated for the year ending December 31, 2013 . The accompanying interim unaudited consolidated financial statements should be read in conjunction with the financial statements and related notes contained in the Company’s 2012 Annual Report on Form 10-K.
Significant Accounting Policies
The significant accounting policies used in preparation of our consolidated financial statements are disclosed in our 2012 Annual Report on Form 10-K. There have not been any changes in our significant accounting policies compared to those contained in our 2012 Form 10-K disclosure for the year ended December 31, 2012 , except for the adoption of ASU 2012-06 as noted below.
2.
Accounting Pronouncements Recently Issued
In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income . The Update requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to present either on the face of the statement where net income is presented, or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. The amendments are effective for annual and interim reporting periods beginning on or after December 15, 2012. The Company adopted the ASU 2013-02 reporting requirements during the current period with no impact to the Company's financial condition or results of operations. See Note 11 to the Consolidated Financial Statements of this report for new disclosures related to accumulated other comprehensive income.
In October 2012, the FASB issued ASU 2012-06, Subsequent Accounting for an Indemnification Asset Recognized at the Acquisition Date as a Result of a Government-Assisted Acquisition of a Financial Institution. ASU 2012-06 clarifies that when a reporting entity recognizes an indemnification asset as a result of a government-assisted acquisition of a financial institution and there is a subsequent change in the amount of cash flows expected to be collected on the indemnified asset, the reporting entity should subsequently measure the indemnification asset on the same basis as the underlying loans by taking into account the contractual limitations of the Loss-Sharing Agreement ("LSA"). For amortization of changes in value, the reporting entity should use the term of the indemnification agreement if it is shorter than the term of the acquired loans. ASU 2012-06 is effective for interim and annual periods beginning after December 15, 2012. The Company adopted the ASU as of January 1, 2013. As a result of the adoption of the ASU, an additional $2.5 million of indemnification asset amortization was recorded during the period, resulting in a reduction of $1.6 million in net income and $0.04 in earnings per share.

At March 31, 2013 , there were 18 U.S. government agency and government-sponsored enterprise mortgage-backed securities & collateralized mortgage obligations securities in an unrealized loss position, of which one was in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where these investments fall within the yield curve and their individual characteristics. Because the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at March 31, 2013 .
At March 31, 2013 , there were 15 state and municipal government securities in an unrealized loss position, of which one was in a continuous loss position for 12 months or more. The unrealized losses on state and municipal securities were caused by interest rate changes or widening of market spreads subsequent to the purchase of the individual securities. Management monitors published credit ratings of these securities for adverse changes. As of March 31, 2013 , none of the rated obligations of state and local government entities held by the Company had a below investment grade credit rating. Because the credit quality of these securities are investment grade and the Company does not intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be upon maturity, the Company does not consider these investments to be other-than-temporarily impaired at March 31, 2013 .
At March 31, 2013 , there were 11 U.S. government agency and government-sponsored enterprise securities in an unrealized loss position, of which none were in a continuous loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates relative to where these investments fall within the yield curve and their individual characteristics. Because the Company does not currently intend to sell these securities nor does the Company consider it more likely than not that it will be required to sell these securities before the recovery of amortized cost basis, which may be maturity, the Company does not consider these investments to be other-than-temporarily impaired at March 31, 2013 .
At March 31, 2013 , there were two U.S. government securities in an unrealized loss position, neither of which was in a continuous loss position for 12 months or more.

currently intend to sell this security nor does the Company consider it more likely than not that it will be required to sell this security before the recovery of amortized cost basis, which may be maturity, the Company does not consider this investment to be other-than-temporarily impaired at March 31, 2013 .
At March 31, 2013 , there was one other security, a mortgage-backed securities fund in a continuous unrealized loss position for 12 months or more. The decline in fair value is attributable to changes in interest rates and the additional risk premium investors are demanding for investment securities with these characteristics. The Company does not consider this investment to be other-than-temporarily impaired at March 31, 2013 as it has the intent and ability to hold the investment for sufficient time to allow for recovery in the market value.

The Company's loans classified as TDR are loans that have been modified or the borrower has been granted special concessions due to financial difficulties that, if not for the challenges of the borrower, the Company would not otherwise consider. The Company had commitments to lend $1.8 million and $236 thousand of additional funds on loans classified as TDR as of March 31, 2013 and December 31, 2012 , respectively. The TDR modifications or concessions are made to increase the likelihood that these borrowers with financial difficulties will be able to satisfy their debt obligations as amended. Credit losses for loans classified as TDR are measured on the same basis as impaired loans. For impaired loans, an allowance is established when the collateral value less selling costs (or discounted cash flows or observable market price) of the impaired loan is lower than the recorded investment of that loan. The Company did not have any loans modified as TDR within the past twelve months that have defaulted during the three months ended March 31, 2013 .

Allowance for Noncovered Loan and Lease Losses and Unfunded Commitments and Letters of Credit
We maintain an allowance for loan and lease losses (“ALLL”) to absorb losses inherent in the loan portfolio. The size of the ALLL is determined through quarterly assessments of the probable estimated losses in the loan portfolio. Our methodology for making such assessments and determining the adequacy of the ALLL includes the following key elements:
1.
General valuation allowance consistent with the Contingencies topic of the FASB Accounting Standards Codification ("ASC").
2.
Classified loss reserves on specific relationships. Specific allowances for identified problem loans are determined in accordance with the Receivables topic of the FASB ASC.
3.
The unallocated allowance provides for other factors inherent in our loan portfolio that may not have been contemplated in the general and specific components of the allowance. This unallocated amount generally comprises less than 5% of the allowance. The unallocated amount is reviewed quarterly based on trends in credit losses, the results of credit reviews and overall economic trends.
The general valuation allowance is systematically calculated quarterly using quantitative and qualitative information about specific loan classes. The minimum required level an entity develops a methodology to determine its allowance for loan and lease losses is by general categories of loans, such as commercial business, real estate, and consumer. However, the Company’s methodology in determining its allowance for loan and lease losses is prepared in a more detailed manner at the loan class level, utilizing specific categories such as commercial business secured, commercial business unsecured, real estate commercial land, and real estate income property multifamily. The quantitative information uses historical losses from a specific loan class and incorporates the loan’s risk rating migration from origination to the point of loss based upon the consideration of an appropriate look back period.
A loan’s risk rating is primarily determined based upon the borrower’s ability to fulfill its debt obligation from a cash flow perspective. In the event there is financial deterioration of the borrower, the borrower’s other sources of income or repayment are also considered, including recent appraisal values for collateral dependent loans. The qualitative information takes into account general economic and business conditions affecting our marketplace, seasoning of the loan portfolio, duration of the business cycle, etc. to ensure our methodologies reflect the current economic environment and other factors as using historical loss information exclusively may not give an accurate estimate of inherent losses within the Company’s loan portfolio.
When a loan is deemed to be impaired, the Company has to determine if a specific valuation allowance is required for that loan. The specific valuation allowance is a reserve, calculated at the individual loan level, for each loan determined to be both impaired and containing a value less than its recorded investment. The Company measures the impairment based on the discounted expected future cash flows, observable market price, or the fair value of the collateral less selling costs if the loan is collateral dependent or if foreclosure is probable. The specific reserve for each loan is equal to the difference between the recorded investment in the loan and its determined impairment value.
The ALLL is increased by provisions for loan and lease losses (“provision”) charged to expense, and is reduced by loans charged off, net of recoveries or a recovery of previous provisions. While the Company’s management believes the best information available is used to determine the ALLL, changes in market conditions could result in adjustments to the ALLL, affecting net income, if circumstances differ from the assumptions used in determining the ALLL.
We have used the same methodology for ALLL calculations during the three months ended March 31, 2013 and 2012 . Adjustments to the percentages of the ALLL allocated to loan categories are made based on trends with respect to delinquencies and problem loans within each class of loans. The Company reviews the ALLL quantitative and qualitative methodology on a quarterly basis and makes adjustments when appropriate. The Company continues to strive towards maintaining a conservative approach to credit quality and will continue to prudently adjust our ALLL as necessary in order to maintain adequate reserves. The Company carefully monitors the loan portfolio and continues to emphasize the importance of credit quality.
Once it is determined that all or a portion of a loan balance is uncollectable, and the amount can be reasonably estimated, the uncollectable portion of the loan is charged-off.

Risk Elements
The extension of credit in the form of loans to individuals and businesses is one of our principal commerce activities. Our policies and applicable laws and regulations require risk analysis as well as ongoing portfolio and credit management. We manage our credit risk through lending limit constraints, credit review, approval policies and extensive, ongoing internal monitoring. We also manage credit risk through diversification of the loan portfolio by type of loan, type of industry, type of borrower and by limiting the aggregation of debt to a single borrower.
The monitoring process for the loan portfolio includes periodic reviews of individual loans with risk ratings assigned to each loan. Based on the analysis, loans are given a risk rating of 1-10 based on the following criteria:
ratings of 1-3 indicate minimal to low credit risk,
ratings of 4-5 indicate an average credit risk with adequate repayment capacity when prolonged periods of adversity do not exist,
rating of 6 indicate higher than average risk requiring greater than routine attention by bank personnel due to conditions affecting the borrower, the borrower's industry or economic environment,
rating of 7 indicate potential weaknesses that, if left uncorrected, may result in deterioration of the repayment prospects for the asset or in the Company's credit position at some future date,
rating of 8 indicates a loss is possible if loan weaknesses are not corrected,
rating of 9 indicates loss is highly probable; however, the amount of loss has not yet been determined,
and a rating of 10 indicates the loan is uncollectable, and when identified is charged-off.
Loans with a risk rating of 1-6 are considered Pass loans and loans with risk ratings of 7, 8, 9 and 10 are considered Special Mention, Substandard, Doubtful and Loss, respectively. Loans with a risk rating of Substandard or worse are reported as classified loans in our allowance for loan and lease losses analysis. We review these loans to assess the ability of our borrowers to service all interest and principal obligations and, as a result, the risk rating may be adjusted accordingly. Risk ratings are reviewed and updated whenever appropriate, with more periodic reviews as the risk and dollar value of loss on the loan increases. In the event full collection of principal and interest is not reasonably assured, the loan is appropriately downgraded and, if warranted, placed on nonaccrual status even though the loan may be current as to principal and interest payments. Additionally, we assess whether an impairment of a loan warrants specific reserves or a write-down of the loan.

7. Covered Assets and FDIC Loss-sharing Asset
Covered Assets
Covered assets consist of loans and OREO acquired in certain FDIC-assisted acquisitions during 2010 and 2011, for which the Bank entered into loss-sharing agreements, whereby the FDIC will cover a substantial portion of future losses on loans (and related unfunded loan commitments), OREO and certain accrued interest on loans during the terms of the agreements. Under the terms of the loss-sharing agreements, the FDIC will absorb 80% of losses and share in 80% of loss recoveries up to specified amounts. With respect to loss-sharing agreements for two acquisitions completed in 2010, after those specified amounts, the FDIC will absorb 95% of losses and share in 95% of loss recoveries. The loss-sharing provisions of the agreements for commercial and single-family mortgage loans are in effect for five and ten years, respectively, from the acquisition dates and the loss recovery provisions are in effect for eight and ten years, respectively, from the acquisition dates.
Ten years and forty-five days after the acquisition dates, the Bank shall pay to the FDIC a clawback in the event the losses from the acquisitions fail to reach stated levels. The amount of the clawback is determined by a formula specified in each individual loss-sharing agreement. As of March 31, 2013 , the net present value of the Bank’s estimated clawback liability is $3.8 million , which is included in other liabilities on the consolidated balance sheets.

Acquired impaired loans are accounted for under ASC 310-30 and initially measured at fair value based on expected future cash flows over the life of the loans. Acquired loans that have common risk characteristics are aggregated into pools. The Company remeasures contractual and expected cash flows, at the pool-level, on a quarterly basis.
Contractual cash flows are calculated based upon the loan pool terms after applying a prepayment factor. Calculation of the applied prepayment factor for contractual cash flows is the same as described below for expected cash flows.
Inputs to the determination of expected cash flows include cumulative default and prepayment data as well as loss severity and recovery lag information. Cumulative default and prepayment data are calculated via a transition matrix. The transition matrix is a matrix of probability values that specifies the probability of a loan pool transitioning into a particular delinquency state (e.g. 0-30 days past due, 31 to 60 days, etc.) given its delinquency state at the remeasurement date. Loss severity factors are based upon either actual charge-off data within the loan pools or industry averages and recovery lags are based upon the collateral within the loan pools.
Acquired impaired loans are also subject to the Company’s internal and external credit review and are risk rated using the same criteria as loans originated by the Company. However, risk ratings are not a clear indicator of losses on acquired loans as the loans were acquired with a significant discount and a majority of the losses are recoverable from the FDIC under the loss-sharing agreements.
Losses attributable to draws on acquired loans, advanced subsequent to the loan acquisition date, are accounted for under ASC 450-20 and those amounts are also subject to the Company’s internal and external credit review. An allowance for loan losses is estimated in a similar manner as the originated loan portfolio, and a provision for loan losses is charged to earnings as necessary.
The excess of cash flows expected to be collected over the initial fair value of acquired loans is referred to as the accretable yield and is accreted into interest income over the estimated life of the acquired loans using the effective yield method. Other adjustments to the accretable yield include changes in the estimated remaining life of the acquired loans, changes in expected cash flows and changes of indices for acquired loans with variable interest rates.

During the three months ended March 31, 2013 , the Company recorded a provision expense for losses on covered loans of $980 thousand . Of this amount, $1.3 million was impairment expense calculated in accordance with ASC 310-30 and $300 thousand was a provision recapture to adjust the allowance for loss calculated under ASC 450-20 for draws on acquired loans. The impact to earnings of the $980 thousand of provision expense for covered loans was partially offset through noninterest income by a $784 thousand increase in the FDIC loss-sharing asset.

The covered OREO is covered by loss-sharing agreements with the FDIC in which the FDIC will share in 80% of additional write-downs, as well as gains and losses on covered OREO sales, or 95% , if applicable, of additional write-downs, as wells as gains and losses on covered OREO sales if the minimum loss share thresholds are met.
FDIC Loss-sharing Asset
At March 31, 2013 , the FDIC loss-sharing asset is comprised of a $75.5 million FDIC indemnification asset and a $7.6 million FDIC receivable. The indemnification represents the cash flows the Company expects to collect from the FDIC under the loss-sharing agreements and the FDIC receivable represents the reimbursable amounts from the FDIC that have not yet been received.
For covered loans, the Company remeasures contractual and expected cash flows on a quarterly basis. When the quarterly remeasurement process results in a decrease in expected cash flows due to an increase in expected credit losses, impairment is recorded. As a result of this impairment, the indemnification asset is increased to reflect anticipated future cash to be received from the FDIC. Consistent with the loss-sharing agreements between the Company and the FDIC, the amount of the increase to the indemnification asset is measured as 80% of the resulting impairment.
Alternatively, when the quarterly remeasurement results in an increase in expected future cash flows due to a decrease in expected credit losses, the nonaccretable difference decreases and the effective yield of the related loan portfolio is increased. As a result of the improved expected cash flows, the indemnification asset would be reduced first by the amount of any impairment previously recorded and, second, by increased amortization over the remaining life of the related loss-sharing agreement.

Goodwill and Intangible Assets
In accordance with the Intangibles – Goodwill and Other topic of the FASB ASC, goodwill is not amortized but is reviewed for potential impairment at the reporting unit level. Management analyzes its goodwill for impairment on an annual basis on July 31 and between annual tests in certain circumstances such as material adverse changes in legal, business, regulatory and economic factors. An impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value.
The core deposit intangible (“CDI”) is evaluated for impairment if events and circumstances indicate a possible impairment. The CDI is amortized on an accelerated basis over an estimated life of approximately 10 years .

Derivatives and Hedging Activities
The Company periodically enters into certain commercial loan interest rate swap agreements in order to provide commercial loan customers the ability to convert from variable to fixed interest rates. Under these agreements, the Company enters into a variable-rate loan agreement with a customer in addition to a swap agreement. This swap agreement effectively converts the customer’s variable rate loan into a fixed rate. The Company then enters into a corresponding swap agreement with a third party in order to offset its exposure on the variable and fixed components of the customer agreement. As the interest rate swap agreements with the customers and third parties are not designated as hedges under the Derivatives and Hedging topic of the FASB ASC, the instruments are marked to market in earnings. The notional amount of open interest rate swap agreements at March 31, 2013 and December 31, 2012 was $158.9 million and $177.0 million , respectively. There was no impact to the statement of operations for the three month periods ending March 31, 2013 and 2012 .

Fair Value Accounting and Measurement
The Fair Value Measurements and Disclosures topic of the FASB ASC defines fair value, establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value. We hold fixed and variable rate interest-bearing securities, investments in marketable equity securities and certain other financial instruments, which are carried at fair value. Fair value is determined based upon quoted prices when available or through the use of alternative approaches, such as matrix or model pricing, when market quotes are not readily accessible or available.
The valuation techniques are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our own market assumptions. These two types of inputs create the following fair value hierarchy:
Level 1 – Quoted prices for identical instruments in active markets that are accessible at the measurement date.
Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model derived valuations whose inputs are observable or whose significant value drivers are observable.
Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable.
Fair values are determined as follows:
Securities at fair value are priced using a combination of market activity, industry recognized information sources, yield curves, discounted cash flow models and other factors. These fair value calculations are considered a Level 2 input method under the provisions of the Fair Value Measurements and Disclosures topic of the FASB ASC for all securities other than U.S. Treasury notes, which are considered a Level 1 input method.
Interest rate contract positions are valued in models, which use as their basis, readily observable market parameters and are classified within Level 2 of the valuation hierarchy.

Nonrecurring Measurements
Certain assets and liabilities are measured at fair value on a nonrecurring basis after initial recognition such as loans measured for impairment and OREO. The following methods were used to estimate the fair value of each such class of financial instrument:
Impaired loans —A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, a loan’s observable market price, or the fair market value of the collateral if the loan is a collateral-dependent loan. Generally, the Company utilizes the fair market value of the collateral to measure impairment. The impairment evaluations are performed in conjunction with the ALLL process on a quarterly basis by officers in the Special Credits group, which reports to the Chief Credit Officer. The Real Estate Appraisal Services Department ("REASD"), which also reports to the Chief Credit Officer, is responsible for obtaining appraisals from third-parties or performing internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisal to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy, and reasonableness.
Other real estate owned and other personal property owned ("OPPO") —OREO and OPPO are real and personal property that the Bank has taken ownership of in partial or full satisfaction of a loan or loans. OREO and OPPO are generally measured based on the item's fair market value as indicated by an appraisal or a letter of intent to purchase. OREO and OPPO are recorded at the lower of carrying amount or fair value less estimated costs to sell. This amount becomes the property’s new basis. Any write-downs based on the property fair value less estimated cost to sell at the date of acquisition are charged to the allowance for loan and lease losses. Management periodically reviews OREO and OPPO in an effort to ensure the property is carried at the lower of its new basis or fair value, net of estimated costs to sell. Any write-downs subsequent to acquisition are charged to earnings. The initial and subsequent write-down evaluations are performed by officers in the Special Credits group, which reports to the Chief Credit Officer. The REASD obtains appraisals from third-parties for OREO and OPPO and performs internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisal to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy, and reasonableness.

Fair value of financial instruments
Because broadly traded markets do not exist for most of the Company’s financial instruments, the fair value calculations attempt to incorporate the effect of current market conditions at a specific time. These determinations are subjective in nature, involve uncertainties and matters of significant judgment and do not include tax ramifications; therefore, the results cannot be determined with precision, substantiated by comparison to independent markets and may not be realized in an actual sale or immediate settlement of the instruments. There may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results. For all of these reasons, the aggregation of the fair value calculations presented herein do not represent, and should not be construed to represent, the underlying value of the Company.
The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value:
Cash and due from banks and interest-earning deposits with banks —The fair value of financial instruments that are short-term or reprice frequently and that have little or no risk are considered to have a fair value that approximates carrying value (Level 1).
Securities available for sale —Securities at fair value, other than U.S. Treasury Notes, are priced using a combination of market activity, industry recognized information sources, yield curves, discounted cash flow models and other factors (Level 2). U.S. Treasury Notes are priced using quotes in active markets (Level 1).
Federal Home Loan Bank stock —The fair value is based upon the par value of the stock which equates to its carrying value (Level 2).
Loans —Loans are not recorded at fair value on a recurring basis . Nonrecurring fair value adjustments are periodically recorded on impaired loans that are measured for impairment based on the fair value of collateral. For most performing loans, fair value is estimated using expected duration and lending rates that would have been offered on March 31, 2013 or December 31, 2012 , for loans which mirror the attributes of the loans with similar rate structures and average maturities. The fair values resulting from these calculations are reduced by an amount representing the change in estimated fair value attributable to changes in borrowers’ credit quality since the loans were originated. For nonperforming loans, fair value is estimated by applying a valuation discount based upon loan sales data from the FDIC. For covered loans, fair value is estimated by discounting the expected future cash flows using a lending rate that would have been offered on March 31, 2013 (Level 3).
FDIC loss-sharing asset —The fair value of the FDIC loss-sharing asset is estimated based on discounting the expected future cash flows using an estimated market rate (Level 3).
Interest rate contracts —Interest rate swap positions are valued in models, which use as their basis, readily observable market parameters (Level 2).
Deposits —For deposits with no contractual maturity, the fair value is equal to the carrying value (Level 1). The fair value of fixed maturity deposits is based on discounted cash flows using the difference between the deposit rate and current market rates for deposits of similar remaining maturities (Level 2).
FHLB advances —The fair value of Federal Home Loan Bank of Seattle (the “FHLB”) advances is estimated based on discounting the future cash flows using the market rate currently offered (Level 2).
Repurchase Agreements —The fair value of securities sold under agreement to repurchase is estimated based on discounting the future cash flows using the market rate currently offered (Level 2).
Other Financial Instruments —The majority of our commitments to extend credit and standby letters of credit carry current market interest rates if converted to loans, as such, carrying value is assumed to equal fair value.

Earnings per Common Share
The Company applies the two-class method of computing basic and diluted EPS. Under the two-class method, EPS is determined for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. The Company grants restricted shares under share-based compensation plans that qualify as participating securities.
The following table sets forth the computation of basic and diluted earnings per share for the three months ended March 31, 2013 and 2012 :

14. Subsequent Events
Subsequent events are events or transactions that occur after the balance sheet date but before financial statements are issued. Recognized subsequent events are events or transactions that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements. Nonrecognized subsequent events are events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date.
On April 1, 2013 , the Company completed its acquisition of West Coast Bancorp ("West Coast"). The Company acquired 100% of the voting equity interests of West Coast. The primary reason for the acquisition was to expand the Company's geographic footprint consistent with its ongoing growth strategy. The operating results of the Company for the three months ended March 31, 2013 do not include the operating results produced by West Coast as the acquisition did not close until April 1, 2013. It is not practical to present financial information related to the acquisition at this time because the fair value measurement of assets acquired and liabilities assumed has not been finalized.

Item 2.
MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
This discussion should be read in conjunction with the unaudited consolidated financial statements of Columbia Banking System, Inc. (referred to in this report as “we”, “our”, and “the Company”) and notes thereto presented elsewhere in this report and with the December 31, 2012 audited consolidated financial statements and its accompanying notes included in our Annual Report on Form 10-K. In the following discussion, unless otherwise noted, references to increases or decreases in average balances in items of income and expense for a particular period and balances at a particular date refer to the comparison with corresponding amounts for the period or date one year earlier.
CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This quarterly report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, statements about our plans, objectives, expectations and intentions that are not historical facts, and other statements identified by words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “should,” “projects,” “seeks,” “estimates” or words of similar meaning. These forward-looking statements are based on current beliefs and expectations of management and are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control. In addition, these forward-looking statements are subject to assumptions with respect to future business strategies and decisions that are subject to change. In addition to the factors set forth in the sections “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this report, the following factors, among others, could cause actual results to differ materially from the anticipated results:
local and national economic conditions could be less favorable than expected or could have a more direct and pronounced effect on us than expected and adversely affect our ability to continue internal growth at historical rates and maintain the quality of our earning assets;
the local housing/real estate markets where we operate and make loans could continue to face challenges;
the risks presented by a continued challenging economy, including the current uncertainty regarding sequestration, which could adversely affect credit quality, collateral values, including real estate collateral, investment values, liquidity and loan originations and loan portfolio delinquency rates;
the inability to smoothly integrate West Coast Bancorp with Columbia and retain customers and employees;
the efficiencies and enhanced financial and operating performance we expect to realize from investments in personnel, acquisitions and infrastructure may not be realized;
interest rate changes could significantly reduce net interest income and negatively affect funding sources;
projected business increases following strategic expansion or opening of new branches could be lower than expected;
our reliance on FHLB advances and FRB borrowings as additional sources of short and long-term funding;
changes in the scope and cost of FDIC insurance and other coverages;
the impact of FDIC-assisted loans on our earnings;
changes in accounting principles, policies, and guidelines applicable to bank holding companies and banking;
competition among financial institutions could increase significantly;
the goodwill we have recorded in connection with acquisitions could become impaired, which may have an adverse impact on our earnings and capital;
the reputation of the financial services industry could deteriorate, which could adversely affect our ability to access markets for funding and to acquire and retain customers;
our ability to effectively manage credit risk, interest rate risk, market risk, operational risk, legal risk, liquidity risk and regulatory and compliance risk; and
our profitability measures could be adversely affected if we are unable to effectively manage our capital.
You should take into account that forward-looking statements speak only as of the date of this report. Given the described uncertainties and risks, we cannot guarantee our future performance or results of operations and you should not place undue reliance on these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required under federal securities laws.

CRITICAL ACCOUNTING POLICIES
Management has identified the accounting policies related to the allowance for loan and lease losses, business combinations, acquired impaired loans, FDIC loss sharing asset and the valuation and recoverability of goodwill as critical to an understanding of our financial statements. These policies and related estimates are discussed in “Item 7. Management Discussion and Analysis of Financial Condition and Results of Operation” under the headings “Allowance for Loan and Lease Losses”, “Business Combinations”, “Acquired Impaired Loans”, "FDIC Loss Sharing Asset” and “Valuation and Recoverability of Goodwill” in our 2012 Annual Report on Form 10-K. There have not been any material changes in our critical accounting policies as compared to those disclosed in our 2012 Annual Report on Form 10-K.
RESULTS OF OPERATIONS
Our results of operations are dependent to a large degree on our net interest income. We also generate noninterest income through service charges and fees, merchant services fees, and bank owned life insurance. Our operating expenses consist primarily of compensation and employee benefits, occupancy, merchant card processing, data processing and legal and professional fees. Like most financial institutions, our interest income and cost of funds are affected significantly by general economic conditions, particularly changes in market interest rates, and by government policies and actions of regulatory authorities.
Earnings Summary
The Company reported net income for the first quarter of $12.2 million or $0.31 per diluted common share, compared to $8.9 million or $0.22 per diluted common share for the first quarter of 2012 .
The increase in net income from the first quarter of 2012 was attributable to lower noninterest expense and provision for loan losses on noncovered loans, partially offset by a reduction in the pretax earnings impact of the acquired loan portfolio.
Revenue (net interest income plus noninterest income) for the three months ended March 31, 2013 was $55.1 million , 28% less than the same period in 2012 . The decrease in revenue was a result of lower incremental accretion income on acquired loans. For a more complete discussion of this topic, please refer to the net interest income section contained in the ensuing pages.
The provision for loan and lease losses for the first quarter of 2013 was a recapture of $1.0 million for the noncovered loan portfolio and a provision of $980 thousand for the covered loan portfolio compared to provisions of $4.5 million for the noncovered loan portfolio and $15.7 million for the covered loan portfolio during the first quarter of 2012 . The $1.0 million provision recapture for the noncovered loan portfolio for the three months ended March 31, 2013 was due to improving credit metrics within the noncovered loan portfolio as well as a $2.0 million recovery experienced during the current quarter related to a single borrowing relationship. The Company believes that, at 1.95% of net noncovered loans, the allowance for loan and lease losses remains adequate at March 31, 2013 . The allowance to net noncovered loans was 2.07% at year-end 2012 . The $980 thousand in provision for losses on covered loans for the three months ended March 31, 2013 was primarily due to decreased expected future cash flows as remeasured during the current quarter when compared to the prior quarter's remeasurement. The $980 thousand in provision is partially off-set by a $784 thousand favorable adjustment to the change in FDIC loss-sharing asset.
Total noninterest expense for the quarter ended March 31, 2013 was $38.0 million , a 14% decrease from the first quarter of 2012 . The decrease from the prior-year period was primarily due to substantial write-downs of OREO and OPPO during the first quarter of the prior year.

Net Interest Income
Net interest income for the first quarter of 2013 was $53.5 million , a decrease of 20% from $67.1 million for the same quarter in 2012 . The Company's net interest margin decreased to 5.06% in the first quarter of 2013 , from 6.67% for the same quarter last year. The decreases in net interest income and margin were primarily due to accretion income on the acquired loan portfolios, which were significantly lower in the current period. In addition to the impact of accretion income, net interest income also decreased due to the combination of lower rates on loans as well as securities due to the overall decreasing trend in rates.
The incremental accretion income represents the amount of income recorded on the acquired loans above the contractual rate stated in the individual loan notes. The incremental accretion income had a positive impact of approximately 87 bps on the first quarter's net interest margin. For the same period last year, the incremental accretion income had a positive impact of approximately 218 bps on the net interest margin.
Incremental accretion income from acquired impaired loans decreased $10.9 million from the prior year period. In addition, the discount accretion on other acquired loans decreased $2.0 million from the prior year period. These decreases were primarily due to the moderating trend for incremental accretion income due to decreases in the acquired loan balances resulting from repayments. For additional information on the Company's accounting policies related to recording interest income on loans, please refer to “Item 8. Financial Statements and Supplementary Data” in our 2012 Annual Report on Form 10-K.

Nonaccrual loans have been included in the tables as loans carrying a zero yield. Amortized net deferred loan fees were included in the interest income calculations. The amortization of net deferred loan fees was $661 thousand and $312 thousand for the three months ended March 31, 2013 and 2012 , respectively. The amortization of net unearned discounts on other acquired loans was $1.1 million and $3.1 million for the three months ended March 31, 2013 and 2012 , respectively.

Tax-exempt income is calculated on a tax equivalent basis, based on a marginal tax rate of 35%. The tax equivalent yield adjustment to interest earned on noncovered loans was $127 thousand and $193 thousand for the three months ended March 31, 2013 and 2012 , respectively. The tax equivalent yield adjustment to interest earned on tax exempt securities was $1.3 million and $1.4 million for the three months ended March 31, 2013 and 2012 , respectively.

Provision for Loan and Lease Losses
The provision for loan and lease losses for the first quarter of 2013 was a recapture of $1.0 million for the noncovered loan portfolio and a provision of $980 thousand for the covered loan portfolio compared with provisions of $4.5 million and $15.7 million , respectively, during the first quarter of 2012 . The $980 thousand in provision for losses on covered loans in the current period was primarily due to the decrease in expected future cash flows from covered loans as remeasured during current quarter, compared to the expected future cash flows as remeasured during the fourth quarter of 2012, net of the actual cash flows received during the quarter. The $980 thousand in provision expense is substantially offset by a $784 thousand favorable adjustment to the change in FDIC loss-sharing asset.
The $1.0 million provision recapture for noncovered loan losses was due to improving credit metrics within the noncovered loan portfolio as well as a $2.0 million recovery experienced during the current quarter related to a single borrowing relationship. Net noncovered loan charge-offs for the current quarter were $125 thousand compared to $5.3 million for the first quarter of 2012 . The amount of provision was calculated in accordance with the Company’s methodology for determining the ALLL, discussed in Note 5 to the Consolidated Financial Statements in "Item 1. Financial Statements (unaudited)" of this report and was based upon improving credit metrics in the noncovered loan portfolio.

Noninterest income was $1.7 million for the first quarter of 2013 , compared to $9.6 million for the same period in 2012 . The decrease was primarily due to the $10.5 million change in the FDIC loss-sharing asset recorded as a reduction in income during the current quarter, compared to a $1.7 million reduction in income during the same period in 2012 . This decrease was partially offset by an increase of $417 thousand in service charges and other fees as well as an increase in other noninterest income of $354 thousand, which was due to an increase in Small Business Administration premiums in the current quarter.
Changes in the FDIC loss-sharing asset are primarily driven by amortization of the FDIC loss-sharing asset and the provision recorded for reimbursable losses on FDIC covered loans. For the first quarter of 2013 , the $9.8 million of amortization of the FDIC loss-sharing asset was partially offset by a $784 thousand increase in the FDIC loss-sharing asset related to the provision recorded for reimbursable losses on FDIC covered loans. For the same period in 2012 , the $13.9 million of amortization of the FDIC loss-sharing asset was partially offset by a $12.5 million increase in the FDIC loss-sharing asset related to the provision expense recorded for reimbursable losses on FDIC covered loans. For additional information on the FDIC loss-sharing asset, please see the "FDIC Loss-sharing Asset" section of Management's Discussion and Analysis and Note 7 to the Consolidated Financial Statements in "Item 1. Financial Statements (unaudited)" of this report.

Total noninterest expense for the first quarter of 2013 was $38.0 million , a decrease of $6.3 million , or 14% from $44.4 million a year earlier. The decrease from the prior-year period was due to a decrease of $2.7 million in other noninterest expense as well as a decrease of $3.4 million in net cost (benefit) of operation of other real estate. The decrease in other noninterest expense was primarily due to the Company recording $2.2 million in OPPO write-downs during the prior year period. The decrease in net cost (benefit) of operation of OREO was due to substantial write-downs recorded in the prior year period. These decreases were partially offset by a $441 thousand increase in legal and professional expenses, which includes $508 thousand during the current quarter related to the acquisition of West Coast Bancorp. Total merger related expense for the current quarter was $723 thousand.

In managing our business, we review the efficiency ratio, on a fully taxable-equivalent basis. Our efficiency ratio (noninterest expense, excluding net cost of operation of other real estate, FDIC clawback liability expense and merger related expenses, divided by the sum of net interest income and noninterest income on a tax equivalent basis, excluding any gain/loss on sale of investment securities, gain on bank acquisition, incremental accretion income on the acquired loan portfolio and the change in the FDIC indemnification asset) was 68.68% for the first quarter of 2013 compared to 71.48% for the first quarter 2012 .
Income Taxes
We recorded an income tax provision of $4.9 million for the first quarter of 2013 , compared to a provision of $3.2 million for the same period in 2012 . The effective tax rate was 29% for the first quarter of 2013 compared to 26% for the first quarter of 2012 . Our effective tax rate remains lower than the statutory tax rate due to our nontaxable income generated from tax-exempt loans and municipal bonds, investments in bank owned life insurance, and low income housing credits. For additional information, please refer to the Company's annual report on Form 10-K for the year ended December 31, 2012 .

FINANCIAL CONDITION
Total assets were $4.91 billion as of March 31, 2013 , relatively unchanged from December 31, 2012 .
Investment Securities
At March 31, 2013 , the Company held investment securities totaling $1.01 billion compared to $1.00 billion at December 31, 2012 . All of our securities are classified as available for sale and carried at fair value. The increase in the investment securities portfolio from year-end is due to $84.7 million in purchases, partially offset by $67.4 million in maturities and sales of securities in the portfolio. These securities are used by t he Company as a component of its balance sheet management strategies. From time-to-time securities may be sold to reposition the portfolio in response to strategies developed by the Company’s asset liability committee. In accordance with our investment strategy, management monitors market conditions with a view to realize gains on its available for sale securities portfolio when prudent.
At March 31, 2013 , the market value of securities available for sale had an unrealized gain of $28.1 million compared to an unrealized gain of $32.3 million at December 31, 2012 . The decrease in the unrealized gain was the result of the fluctuations in interest rates. The Company does carry $352.0 million of investment securities with unrealized losses of $7.9 million ; however, we do not consider these investment securities to be other-than-temporarily impaired. In the future, if the impairment is judged to be other-than-temporary, to the extent that the loss is determined to be credit-related, the cost basis of the individual impaired securities will be written down to fair value; the amount of the write-down could be included in earnings as a realized loss. The remaining non-credit-related impairment would be recorded to other comprehensive income.

Credit Risk Management
The extension of credit in the form of loans or other credit products to individuals and businesses is one of our principal business activities. Our policies and applicable laws and regulations require risk analysis as well as ongoing portfolio and credit management. We manage our credit risk through lending limit constraints, credit review, approval policies, and extensive, ongoing internal monitoring. We also manage credit risk through diversification of the loan portfolio by type of loan, type of industry, type of borrower and by limiting the aggregation of debt limits to a single borrower. The monitoring process for our loan portfolio includes periodic reviews of individual loans with risk ratings assigned to each loan. We review these loans to assess the ability of the borrower to service all of its interest and principal obligations and, as a result, the risk rating may be adjusted accordingly. In the event that full collection of principal and interest is not reasonably assured, the loan is appropriately downgraded and, if warranted, placed on nonaccrual status even though the loan may be current as to principal and interest payments. Additionally, we review these types of loans for impairment in accordance with the Receivables topic of the FASB ASC. Impaired loans are considered for nonaccrual status and will typically remain as such until all principal and interest payments are brought current and the prospects for future payments in accordance with the loan agreement appear relatively certain.
Loan policies, credit quality criteria, loan portfolio guidelines and other credit approval processes are established under the guidance of our Chief Credit Officer and approved, as appropriate, by the Board of Directors. The Company’s Credit Administration department and loan committee have the responsibility for administering the credit approval process. As another part of its control process, we use an independent internal credit review and examination function to provide assurance that

loans and commitments are made and maintained as prescribed by our credit policies. This includes a review of documentation when the loan is initially extended and subsequent monitoring to assess continued performance and proper risk assessment.

Total noncovered loans increased $95.5 million , or 4% , from year-end 2012 . Growth was centered in the commercial business loan segment which increased $49.6 million. Growth in this segment was led by the healthcare industry. There was also strong broad based growth in the commercial and multifamily residential real estate loans. The growth in business and commercial real estate loans was partially offset by small reduction in consumer loans. The noncovered loan portfolio continues to be diversified, with the intent to mitigate risk by minimizing concentration in any one segment.
Commercial Loans: We are committed to providing competitive commercial lending in our primary market areas. Management expects a continued focus within its commercial lending products and to emphasize, in particular, relationship banking with businesses, and business owners.
Real Estate Loans: One-to-four family residential loans are secured by properties located within our primary market areas and, typically, have loan-to-value ratios of 80% or lower at origination. Our underwriting standards for commercial and multifamily residential loans generally require that the loan-to-value ratio for these loans not exceed 75% of appraised value, cost, or discounted cash flow value, as appropriate, and that commercial properties maintain debt coverage ratios (net operating income divided by annual debt servicing) of 1.2 or better. However, underwriting standards can be influenced by competition and other factors. We endeavor to maintain the highest practical underwriting standards while balancing the need to remain competitive in our lending practices.

Real Estate Construction Loans: We originate a variety of real estate construction loans. Underwriting guidelines for these loans vary by loan type but include loan-to-value limits, term limits and loan advance limits, as applicable. Our underwriting guidelines for commercial and multifamily residential real estate construction loans generally require that the loan-to-value ratio not exceed 75% and stabilized debt coverage ratios (net operating income divided by annual debt servicing) of 1.2 or better. As noted above, underwriting standards can be influenced by competition and other factors. However, we endeavor to maintain the highest practical underwriting standards while balancing the need to remain competitive in our lending practices.
Consumer Loans: Consumer loans include automobile loans, boat and recreational vehicle financing, home equity and home improvement loans and miscellaneous personal loans.
Foreign Loans:  The Company has no material foreign activities. Substantially all of the Company’s loans and unfunded commitments are geographically concentrated in its service areas within the states of Washington and Oregon.
Covered Loans: Covered loans are comprised of loans and loan commitments acquired in connection with the 2011 FDIC-assisted acquisitions of First Heritage Bank and Summit Bank, as well as the 2010 FDIC-assisted acquisitions of Columbia River Bank and American Marine Bank. These loans are generically referred to as covered because they are generally subject to one of the loss-sharing agreements between the Company and the FDIC. The loss-sharing agreements relating to the 2010 FDIC-assisted transactions limit the Company’s losses to 20% of the contractual balance outstanding up to a stated threshold amount of $206.0 million for Columbia River Bank and $66.0 million for American Marine Bank. If losses exceed the stated threshold, the Company’s share of the remaining losses decreases to 5%. The loss-sharing agreements relating to the 2011 FDIC-assisted transactions limit the Company's losses to 20% of the contractual balance outstanding. The loss-sharing provisions of the 2011 agreements for commercial and single family residential mortgage loans are in effect for five years and ten years, respectively, from the acquisition dates and the loss recovery provisions for such loans are in effect for eight years and ten years, respectively, from the acquisition dates.

Nonperforming Assets
Nonperforming assets consist of: (i) nonaccrual loans; (ii) other real estate owned; and (iii) other personal property owned.
Nonaccrual noncovered loans : The consolidated financial statements are prepared according to the accrual basis of accounting. This includes the recognition of interest income on the loan portfolio, unless a loan is placed on a nonaccrual basis, which occurs when there are serious doubts about the collectability of principal or interest. Generally our policy is to discontinue the accrual of interest on all loans past due 90 days or more and place them on nonaccrual status. When a noncovered loan is placed on nonaccrual status, any accrued but unpaid interest on that date is removed from interest income.
Covered loans : We consider covered loans to be performing due to the application of the yield accretion method under ASC Topic 310-30. Topic 310-30 allows us to aggregate credit-impaired loans acquired in the same fiscal quarter into one or more pools, provided the loans have common risk characteristics. A pool is then accounted for as a single asset with a single composite interest rate and an aggregate expectation of cash flows. The covered loans acquired are and will continue to be subject to the Company’s internal and external credit review and monitoring. Any credit deterioration experienced subsequent to the initial acquisition will result in a provision for loan losses being charged to earnings. These provisions will be mostly offset by an increase to the FDIC loss-sharing asset and will be recognized in noninterest income.

Allowance for Loan and Lease Losses
We maintain an allowance for loan and lease losses (“ALLL”) to absorb losses inherent in the loan portfolio. The size of the ALLL is determined through quarterly assessments of the probable estimated losses in the loan portfolio. Our methodology for making such assessments and determining the adequacy of the ALLL includes the following key elements:
1.
General valuation allowance consistent with the Contingencies topic of the FASB ASC.
2.
Classified loss reserves on specific relationships. Specific allowances for identified problem loans are determined in accordance with the Receivables topic of the FASB ASC.
3.
The unallocated allowance provides for other credit losses inherent in our loan portfolio that may not have been contemplated in the general and specific components of the allowance. This unallocated amount generally comprises less than 5% of the allowance. The unallocated amount is reviewed periodically based on trends in credit losses, the results of credit reviews and overall economic trends.
On a quarterly basis our Chief Credit Officer reviews with Executive Management and the Board of Directors the various additional factors that management considers when determining the adequacy of the ALLL, including economic and business condition reviews. Factors which influenced management’s judgment in determining the amount of the additions to the ALLL charged to operating expense include the following as of the applicable balance sheet dates:
Existing general economic and business conditions affecting our market place
Credit quality trends
Historical loss experience
Seasoning of the loan portfolio
Bank regulatory examination results
Findings of internal credit examiners
Duration of current business cycle
Specific loss estimates for problem loans

45

Table of Contents

The ALLL is increased by provisions for loan and lease losses (“provision”) charged to expense, and is reduced by loans charged off, net of recoveries and recapture of previous provision. While we believe the best information available is used by us to determine the ALLL, changes in market conditions could result in adjustments to the ALLL, affecting net income, if circumstances differ from the assumptions used in determining the ALLL.
In addition to the ALLL, we maintain an allowance for unfunded commitments and letters of credit. We report this allowance as a liability on our Consolidated Balance Sheet. We determine this amount using estimates of the probability of the ultimate funding and losses related to those credit exposures. This methodology is similar to the methodology we use for determining the adequacy of our ALLL. For additional information on our allowance for unfunded commitments and letters of credit, see Note 5 to the Consolidated Financial Statements presented elsewhere in this report.
At March 31, 2013 , our allowance for loan and lease losses for noncovered loans was $51.1 million , or 1.95% of total noncovered loans (excluding loans held for sale) and 155% of nonperforming, noncovered loans. This compares with an allowance of $52.2 million , or 2.07% of total noncovered loans (excluding loans held for sale), and 140% of nonperforming, noncovered loans at December 31, 2012 .

FDIC Loss-sharing Asset
The Company has elected to account for amounts receivable under loss-sharing agreements with the FDIC as an indemnification asset in accordance with the Business Combinations topic of the FASB ASC. The FDIC indemnification asset is initially recorded at fair value, based on the discounted expected future cash flows under the loss-sharing agreements.
Subsequent to initial recognition, the FDIC indemnification asset is reviewed quarterly and adjusted for any changes in expected cash flows. These adjustments are measured on the same basis as the related covered loans. Any decrease in expected cash flows from the covered assets due to an increase in expected credit losses will increase the FDIC indemnification asset and any increase in expected future cash flows from the covered assets due to a decrease in expected credit losses will decrease the FDIC indemnification asset. Increases and decreases to the FDIC loss-sharing asset are recorded as adjustments to noninterest income.
At March 31, 2013 , the FDIC loss-sharing asset was $83.1 million which was comprised of a $75.5 million FDIC indemnification asset and a $7.6 million FDIC receivable. The FDIC receivable represents the amounts due from the FDIC for claims related to covered losses the Company has incurred net of amounts due to the FDIC relating to shared recoveries.
The following table summarizes the activity related to the FDIC loss-sharing asset for the three months ended March 31, 2013 and 2012 :

Liquidity and Sources of Funds
Our primary sources of funds are customer deposits. Additionally, we utilize advances from the FHLB of Seattle, the FRB of San Francisco, and wholesale repurchase agreements to supplement our funding needs. These funds, together with loan repayments, loan sales, retained earnings, equity and other borrowed funds are used to make loans, to acquire securities and other assets, and to fund continuing operations.
Deposit Activities
Our deposit products include a wide variety of transaction accounts, savings accounts and time deposit accounts. Core deposits (demand deposit, savings, money market accounts and certificates of deposit less than $100,000) were relatively unchanged since year-end 2012 while certificates of deposit greater than $100,000 decreased $8.4 million , or approximately 4% , to $204.5 million from year-end 2012 .

47

Table of Contents

We have established a branch system to serve our consumer and business depositors. In addition, management’s strategy for funding asset growth is to make use of brokered and other wholesale deposits on an as-needed basis. The Company also participates in the Certificate of Deposit Account Registry Service (CDARS ® ) program. CDARS ® is a network that allows participating banks to offer extended FDIC deposit insurance coverage on certificates of deposit. Unlike traditional brokered deposits, the Company generally makes CDARS ® available only to existing customers who desire additional deposit insurance coverage rather than as a means of generating additional liquidity. At March 31, 2013 CDARS ® deposits and other brokered deposits were $45.4 million , or 1% of total deposits, compared to $26.7 million at year-end 2012 . The brokered deposits have varied maturities.

Borrowings
We rely on FHLB advances and FRB borrowings as another source of both short and long-term funding. FHLB advances and FRB borrowings are secured by bonds within our investment portfolio, residential, commercial and commercial real estate loans. At March 31, 2013 and December 31, 2012 , we had FHLB advances of $6.0 million, bef ore acquisition date fair value adjustments.

We also utilize wholesale repurchase agreements as a supplement to our funding sources. Our wholesale repurchase agreements are secured by mortgage-backed securities. At March 31, 2013 and December 31, 2012 we had repurchase agreem ents of $25.0 million, wh ich mature in 2018. Management anticipates we will continue to rely on FHLB advances, FRB borrowings, and wholesale repurchase agreements in the future and we will use those funds primarily to make loans and purchase securities.

Contractual Obligations & Commitments
We are party to many contractual financial obligations, including repayment of borrowings, operating and equipment lease payments, commitments to extend credit an d investments in affordable housing partnerships. At March 31, 2013 , we had commitments to extend credit of $924.4 million compared to $908.5 million at December 31, 2012 .
Capital Resources
Shareholders’ equity at March 31, 2013 was $769.7 million , a slig ht increase from $764.0 million at December 31, 2012 . Shareholders’ equity was 16% of total period-end assets at both March 31, 2013 and December 31, 2012 .
Capital Ratios : Banking regulations require bank holding companies to maintain a minimum “leverage” ratio of core capital to adjusted quarterly average total assets of at least 3%. In addition, banking regulators have adopted risk-based capital guidelines, under which risk percentages are assigned to various categories of assets and off-balance sheet items to calculate a risk-adjusted capital ratio. Tier I capital generally consists of preferred stock, common shareholders’ equity, and trust preferred obligations, less goodwill and certain identifiable intangible assets, while Tier II capital includes the allowance for loan losses and subordinated debt, both subject to certain limitations. Regulatory minimum risk-based capital guidelines require Tier I capital of 4% of risk-adjusted assets and total capital (combined Tier I and Tier II) of 8% to be considered “adequately capitalized”.
Federal Deposit Insurance Corporation regulations set forth the qualifications necessary for a bank to be classified as “well capitalized”, primarily for assignment of FDIC insurance premium rates. To qualify as “well capitalized,” banks must have a Tier I risk-adjusted capital ratio of at least 6%, a total risk-adjusted capital ratio of at least 10%, and a leverage ratio of at least 5%. Failure to qualify as “well capitalized” can negatively impact a bank’s ability to expand and to engage in certain activities.
The Company and its subsidiary qualify as “well-capitalized” at March 31, 2013 and December 31, 2012 .

Stock Repurchase Program
In 2011, the Board of Directors approved a stock repurchase program authorizing the Company to repurchase up to 2 million shares of its outstanding shares of common stock. The Company intends to purchase the shares from time to time in the open market or in private transactions, under conditions which allow such repurchases to be accretive to earnings per share while maintaining capital ratios that exceed the guidelines for a well-capitalized financial institution. No shares were repurchased under the stock repurchase program during the first three months of 2013 .

Item 3.
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
A number of measures are used to monitor and manage interest rate risk, including income simulations and interest sensitivity (gap) analysis. An income simulation model is the primary tool used to assess the direction and magnitude of changes in net interest income resulting from changes in interest rates. Basic assumptions in the model include prepayment speeds on mortgage-related assets, cash flows and maturities of other investment securities, loan and deposit volumes and pricing. These assumptions are inherently subjective and, as a result, the model cannot precisely estimate net interest income or precisely predict the impact of higher or lower interest rates on net interest income. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes and changes in market conditions and management strategies, among other factors. At March 31, 2013 , based on the measures used to monitor and manage interest rate risk, there has not been a material change in the Company’s interest rate risk since December 31, 2012 . For additional information, refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s 2012 Annual Report on Form 10-K.
Item 4.
CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
An evaluation was carried out under the supervision and with the participation of the Company’s management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934). Based on that evaluation, the CEO and CFO have concluded that as of the end of the period covered by this report, our disclosure controls and procedures are effective in ensuring that the information required to be disclosed by us in the reports we file or submit under the Securities Exchange Act of 1934 is (i) accumulated and communicated to our management (including the CEO and CFO) to allow timely decisions regarding required disclosure, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
Changes in Internal Controls Over Financial Reporting
There was no change in our internal controls over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal controls over financial reporting.

Item 1.
LEGAL PROCEEDINGS
On June 24, 2009, West Coast Trust, which as a result of our recent acquisition of West Coast Bancorp (“West Coast”) is now a subsidiary of the Company, was served with an Objection to Personal Representative's Petition and Petition for Surcharge of Personal Representative in Linn County Circuit Court. The petition was filed by the beneficiaries of the estate of Archie Q. Adams, for which West Coast Trust acts as the personal representative. The petitioners allege a breach of fiduciary duty with respect to West Coast Trust's prior sale of real property owned by the Adams estate and sought relief in the form of a surcharge to West Coast Trust of $215.6 million, the amount of the alleged loss to the estate. West Coast Trust filed a motion to dismiss on July 2, 2009, which was granted in a letter ruling dated September 15, 2009. Petitioners appealed and briefs have been filed. Appeals Court oral arguments were heard in November, 2012, and the Company has not yet received the Appeals Court decision. The Company believes the appeal and underlying petition are without merit.
On October 3, 2012, a class action complaint was filed in the Circuit Court of the State of Oregon for the County of Multnomah against West Coast, its directors, and the Company challenging the merger: Gary M. Klein v. West Coast Bancorp, et al., Case No. 1210-12431. The complaint names as defendants West Coast, all of the current members of West Coast's board of directors, and the Company. The complaint alleges that the West Coast directors breached their fiduciary duties to West Coast and West Coast shareholders by agreeing to the proposed merger at an unfair price. The complaint also alleges that the proposed merger is being driven by an unfair process, that the directors approved provisions in the merger agreement that constitute preclusive deal protection devices, that certain large shareholders of West Coast are using the merger as an opportunity to sell their illiquid holdings in West Coast, and that West Coast directors and officers will obtain personal benefits from the merger not shared equally by other West Coast shareholders. The complaint further alleges that West Coast and the Company aided and abetted the directors' alleged breaches of their fiduciary duties. Thereafter, a second lawsuit challenging the merger was filed in the Circuit Court of the State of Oregon for Clackamas County: Leoni v. West Coast Bancorp et al., Case No. CV12100728. The parties have previously stipulated to the consolidation of the two lawsuits for all purposes in the Circuit Court of the State of Oregon for Multnomah County, and the Company and West Coast have consented to the filing of an unopposed motion to consolidate both lawsuits and extending the time for defendants to file a responsive pleading until July 5, 2013.

While West Coast believes that the claims in both complaints are without merit, West Coast agreed, in order to avoid the expense and burden of continued litigation and pursuant to the terms of the proposed settlement, to make certain supplemental disclosures in the joint proxy statement/prospectus related to the merger. Accordingly, prior to the closing of the merger on April 1, 2013, West Coast and the other defendants in the two actions entered into a memorandum of understanding to settle both actions. Subject to completion of certain confirmatory discovery by plaintiffs' counsel, the memorandum of understanding contemplates that the parties will enter into a stipulation of settlement. The stipulation of settlement will be subject to customary conditions, including court approval following notice to West Coast's stoc kholders. In the event that the parties enter into a stipulation of settlement, a hearing will be scheduled at which the Circuit Court of the State of Oregon for Multnomah County will consider the fairness, reasonableness, and adequacy of the settlement. If the settlement is finally approved by the court, it will resolve and release all claims in all actions that were or could have been brought challenging any aspect o f the merger, the merger agreement, and any disclosure made in connection therewith, pursuant to terms that will be disclosed to stockholders before final approval of the settlement. There can be no assurance that the parties will ultimately enter into a stipulation of settlement or that the Circuit Court of the State of Oregon for Multnomah County will approve the settlement even if the parties were to enter into such stipulation. In such event, the proposed settlement as contemplated by the memorandum of understanding may be terminated.

Item 1A. RISK FACTORS
Refer to Item 1A of Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 for a discussion of risk factors relating to the Company’s business. The Company believes that there has been no material change in its risk factors as previously disclosed in the Company’s Form 10-K, except for the following additional risk factor.
Significant legal actions could subject us to substantial uninsured liabilities and reputational harm and have a material adverse effect on our business and results of operations.
We are from time to time subject to claims and proceedings related to our operations, which now include certain legal proceedings we assumed in connection with our recent acquisition of West Coast. Such claims and legal actions could involve large monetary claims, including civil money penalties or fines imposed by government authorities, and significant defense costs.  In that regard, we are currently involved in active assumed legal proceedings. If one or more of those legal proceedings is decided in a manner that is adverse to us it could have a material adverse effect on our business and/or results of operation.
To protect against financial exposure from such claims, we maintain insurance coverage in amounts and with deductibles that we believe are appropriate for our operations. However, our insurance coverage does not cover any civil money penalties or fines imposed by government authorities and may not cover all other claims that might be brought against us or continue to be available to us at a reasonable cost. As a result, we may be exposed to substantial uninsured liabilities, which could adversely affect our business, prospects, results of operations and financial condition. Substantial uninsured legal action against us could have material adverse financial effects or cause significant reputational harm to us, which in turn could harm our business prospects.

In the event that any Dividend Payment Date would otherwise fall on a day that is not a Business Day, the dividend payment due on that date will be postponed to the next day that is a Business Day and no additional dividends will accrue as a result of that postponement. The period from and including any Dividend Payment Date to, but excluding, the next Dividend Payment Date is a “Dividend Period”, provided that the initial Dividend Period shall be the period from and including the Original Issue Date to, but excluding, the next Dividend Payment Date.
Dividends that are payable on Designated Preferred Stock in respect of any Dividend Period shall be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of dividends payable on Designated Preferred Stock on any date prior to the end of a Dividend Period, and for the initial Dividend Period, shall be computed on the basis of a 360-day year consisting of twelve 30-day months, and actual days elapsed over a 30-day month.
Dividends that are payable on Designated Preferred Stock on any Dividend Payment Date will be payable to holders of record of Designated Preferred Stock as they appear on the stock register of the Corporation on the applicable record date, which shall be the 15th calendar day immediately preceding such Dividend Payment Date or such other record date fixed by the Board of Directors or any duly authorized committee of the Board of Directors that is not more than 60 nor less than 10 days prior to such Dividend Payment Date (each, a “Dividend Record Date”). Any such day that is a Dividend Record Date shall be a Dividend Record Date whether or not such day is a Business Day.
Holders of Designated Preferred Stock shall not be entitled to any dividends, whether payable in cash, securities or other property, other than dividends (if any) declared and payable on Designated Preferred Stock as specified in this Section 3 (subject to the other provisions of the Certificate of Designations).
(b)      Priority of Dividends . So long as any share of Designated Preferred Stock remains outstanding, no dividend or distribution shall be declared or paid on the Common Stock or any other shares of Junior Stock (other than dividends payable solely in shares of Common Stock) or Parity Stock, subject to the immediately following paragraph in the case of Parity Stock, and no Common Stock, Junior Stock or Parity Stock shall be, directly or indirectly, purchased, redeemed or otherwise acquired for consideration by the Corporation or any of its subsidiaries unless all accrued and unpaid dividends for all past Dividend

3


Periods, including the latest completed Dividend Period (including, if applicable as provided in Section 3(a) above, dividends on such amount), on all outstanding shares of Designated Preferred Stock have been or are contemporaneously declared and paid in full (or have been declared and a sum sufficient for the payment thereof has been set aside for the benefit of the holders of shares of Designated Preferred Stock on the applicable record date). The foregoing limitation shall not apply to (i) redemptions, purchases or other acquisitions of shares of Common Stock or other Junior Stock in connection with the administration of any employee benefit plan in the ordinary course of business (including purchases to offset the Share Dilution Amount (as defined below) pursuant to a publicly announced repurchase plan) and consistent with past practice, provided that any purchases to offset the Share Dilution Amount shall in no event exceed the Share Dilution Amount; (ii) purchases or other acquisitions by a broker-dealer subsidiary of the Corporation solely for the purpose of market-making, stabilization or customer facilitation transactions in Junior Stock or Parity Stock in the ordinary course of its business; (iii) purchases by a broker-dealer subsidiary of the Corporation of capital stock of the Corporation for resale pursuant to an offering by the Corporation of such capital stock underwritten by such broker-dealer subsidiary; (iv) any dividends or distributions of rights or Junior Stock in connection with a stockholders’ rights plan or any redemption or repurchase of rights pursuant to any stockholders’ rights plan; (v) the acquisition by the Corporation or any of its subsidiaries of record ownership in Junior Stock or Parity Stock for the beneficial ownership of any other persons (other than the Corporation or any of its subsidiaries), including as trustees or custodians; and (vi) the exchange or conversion of Junior Stock for or into other Junior Stock or of Parity Stock for or into other Parity Stock (with the same or lesser aggregate liquidation amount) or Junior Stock, in each case, solely to the extent required pursuant to binding contractual agreements entered into prior to the Signing Date or any subsequent agreement for the accelerated exercise, settlement or exchange thereof for Common Stock. “Share Dilution Amount” means the increase in the number of diluted shares outstanding (determined in accordance with generally accepted accounting principles in the United States, and as measured from the date of the Corporation’s consolidated financial statements most recently filed with the Securities and Exchange Commission prior to the Original Issue Date) resulting from the grant, vesting or exercise of equity-based compensation to employees and equitably adjusted for any stock split, stock dividend, reverse stock split, reclassification or similar transaction.
When dividends are not paid (or declared and a sum sufficient for payment thereof set aside for the benefit of the holders thereof on the applicable record date) on any Dividend Payment Date (or, in the case of Parity Stock having dividend payment dates different from the Dividend Payment Dates, on a dividend payment date falling within a Dividend Period related to such Dividend Payment Date) in full upon Designated Preferred Stock and any shares of Parity Stock, all dividends declared on Designated Preferred Stock and all such Parity Stock and payable on such Dividend Payment Date (or, in the case of Parity Stock having dividend payment dates different from the Dividend Payment Dates, on a dividend payment date falling within the Dividend Period related to such Dividend Payment Date) shall be declared pro rata so that the respective amounts of such dividends declared shall bear the same ratio to each other as all accrued and unpaid dividends per share on the shares of Designated Preferred Stock (including, if applicable as provided in Section 3(a) above, dividends on such amount) and all Parity Stock payable on such Dividend Payment Date (or, in the case of Parity Stock having dividend payment dates different from the Dividend Payment Dates, on a dividend payment date falling within the Dividend Period related to such Dividend Payment Date) (subject to their having been declared by the Board of Directors or a duly authorized committee of the Board of Directors out of legally available funds and including, in the case of Parity Stock that bears cumulative dividends, all accrued but unpaid dividends) bear to each other. If the Board of Directors or a duly authorized committee of the Board of Directors determines not to pay any dividend or a full dividend on a Dividend Payment Date, the Corporation will provide written notice to the holders of Designated Preferred Stock prior to such Dividend Payment Date.

4


Subject to the foregoing, and not otherwise, such dividends (payable in cash, securities or other property) as may be determined by the Board of Directors or any duly authorized committee of the Board of Directors may be declared and paid on any securities, including Common Stock and other Junior Stock, from time to time out of any funds legally available for such payment, and holders of Designated Preferred Stock shall not be entitled to participate in any such dividends.
Section 4.      Liquidation Rights .
(a)      Voluntary or Involuntary Liquidation . In the event of any liquidation, dissolution or winding up of the affairs of the Corporation, whether voluntary or involuntary, holders of Designated Preferred Stock shall be entitled to receive for each share of Designated Preferred Stock, out of the assets of the Corporation or proceeds thereof (whether capital or surplus) available for distribution to stockholders of the Corporation, subject to the rights of any creditors of the Corporation, before any distribution of such assets or proceeds is made to or set aside for the holders of Common Stock and any other stock of the Corporation ranking junior to Designated Preferred Stock as to such distribution, payment in full in an amount equal to the sum of (i) the Liquidation Amount per share and (ii) the amount of any accrued and unpaid dividends (including, if applicable as provided in Section 3(a) above, dividends on such amount), whether or not declared, to the date of payment (such amounts collectively, the “ Liquidation Preference ”).
(b)      Partial Payment . If in any distribution described in Section 4(a) above the assets of the Corporation or proceeds thereof are not sufficient to pay in full the amounts payable with respect to all outstanding shares of Designated Preferred Stock and the corresponding amounts payable with respect of any other stock of the Corporation ranking equally with Designated Preferred Stock as to such distribution, holders of Designated Preferred Stock and the holders of such other stock shall share ratably in any such distribution in proportion to the full respective distributions to which they are entitled.
(c)      Residual Distributions . If the Liquidation Preference has been paid in full to all holders of Designated Preferred Stock and the corresponding amounts payable with respect of any other stock of the Corporation ranking equally with Designated Preferred Stock as to such distribution has been paid in full, the holders of other stock of the Corporation shall be entitled to receive all remaining assets of the Corporation (or proceeds thereof) according to their respective rights and preferences.
(d)      Merger, Consolidation and Sale of Assets Not Liquidation . For purposes of this Section 4, the merger or consolidation of the Corporation with any other corporation or other entity, including a merger or consolidation in which the holders of Designated Preferred Stock receive cash, securities or other property for their shares, or the sale, lease or exchange (for cash, securities or other property) of all or substantially all of the assets of the Corporation, shall not constitute a liquidation, dissolution or winding up of the Corporation.
Section 5.      Redemption .
(a)      Optional Redemption . Except as provided below, the Designated Preferred Stock may not be redeemed prior to the first Dividend Payment Date falling on or after the third anniversary of the Original Issue Date.

Notwithstanding the foregoing, prior to the first Dividend Payment Date falling on or after the third anniversary of the Original Issue Date, the Corporation, at its option, subject to the approval of the Appropriate Federal Banking Agency, may redeem, in whole or in part, at any time and from time to time, the shares of Designated Preferred Stock at the time outstanding, upon notice given as provided in Section 5(c) below, at a redemption price equal to the sum of (i) the Liquidation Amount per share and (ii) except as otherwise provided below, any accrued and unpaid dividends (including, if applicable as provided in Section 3(a) above, dividends on such amount) (regardless of whether any dividends are actually declared) to, but excluding, the date fixed for redemption; provided that (x) the Corporation (or any successor by Business Combination) has received aggregate gross proceeds of not less than the Minimum Amount (plus the “Minimum Amount” as defined in the relevant certificate of designations for each other outstanding series of preferred stock of such successor that was originally issued to the United States Department of the Treasury (the “Successor Preferred Stock”) in connection with the Troubled Asset Relief Program Capital Purchase Program) from one or more Qualified Equity Offerings (including Qualified Equity Offerings of such successor), and (y) the aggregate redemption price of the Designated Preferred Stock (and any Successor Preferred Stock) redeemed pursuant to this paragraph may not exceed the aggregate net cash proceeds received by the Corporation (or any successor by Business Combination) from such Qualified Equity Offerings (including Qualified Equity Offerings of such successor).
The redemption price for any shares of Designated Preferred Stock shall be payable on the redemption date to the holder of such shares against surrender of the certificate(s) evidencing such shares to the Corporation or its agent. Any declared but unpaid dividends payable on a redemption date that occurs subsequent to the Dividend Record Date for a Dividend Period shall not be paid to the holder entitled to receive the redemption price on the redemption date, but rather shall be paid to the holder of record of the redeemed shares on such Dividend Record Date relating to the Dividend Payment Date as provided in Section 3 above.
(b)      No Sinking Fund . The Designated Preferred Stock will not be subject to any mandatory redemption, sinking fund or other similar provisions. Holders of Designated Preferred Stock will have no right to require redemption or repurchase of any shares of Designated Preferred Stock.

Such mailing shall be at least 30 days and not more than 60 days before the date fixed for redemption. Any notice mailed as provided in this Subsection shall be conclusively presumed to have been duly given, whether or not the holder receives such notice, but failure duly to give such notice by mail, or any defect in such notice or in the mailing thereof, to any holder of shares of Designated Preferred Stock designated for redemption shall not affect the validity of the proceedings for the redemption of any other shares of Designated Preferred Stock. Notwithstanding the foregoing, if shares of Designated Preferred Stock are issued in book-entry form through The Depository Trust Corporation or any other similar facility, notice of redemption may be given to the holders of Designated Preferred Stock at such time and in any manner permitted by such facility. Each notice of redemption given to a holder shall state: (1) the redemption date; (2) the number of shares of Designated Preferred Stock to be redeemed and, if less than all the shares held by such holder are to be redeemed, the number of such shares to be redeemed from such holder; (3) the redemption price; and (4) the place or places where certificates for such shares are to be surrendered for payment of the redemption price.
(d)      Partial Redemption . In case of any redemption of part of the shares of Designated Preferred Stock at the time outstanding, the shares to be redeemed shall be selected either pro rata or in such other manner as the Board of Directors or a duly authorized committee thereof may determine to be fair and equitable.

shall have full power and authority to prescribe the terms and conditions upon which shares of Designated Preferred Stock shall be redeemed from time to time. If fewer than all the shares represented by any certificate are redeemed, a new certificate shall be issued representing the unredeemed shares without charge to the holder thereof.
(e)      Effectiveness of Redemption . If notice of redemption has been duly given and if on or before the redemption date specified in the notice all funds necessary for the redemption have been deposited by the Corporation, in trust for the pro rata benefit of the holders of the shares called for redemption, with a bank or trust company doing business in the Borough of Manhattan, The City of New York, and having a capital and surplus of at least $500 million and selected by the Board of Directors, so as to be and continue to be available solely therefor, then, notwithstanding that any certificate for any share so called for redemption has not been surrendered for cancellation, on and after the redemption date dividends shall cease to accrue on all shares so called for redemption, all shares so called for redemption shall no longer be deemed outstanding and all rights with respect to such shares shall forthwith on such redemption date cease and terminate, except only the right of the holders thereof to receive the amount payable on such redemption from such bank or trust company, without interest. Any funds unclaimed at the end of three years from the redemption date shall, to the extent permitted by law, be released to the Corporation, after which time the holders of the shares so called for redemption shall look only to the Corporation for payment of the redemption price of such shares.
(f)      Status of Redeemed Shares . Shares of Designated Preferred Stock that are redeemed, repurchased or otherwise acquired by the Corporation shall revert to authorized but unissued shares of Preferred Stock ( provided that any such cancelled shares of Designated Preferred Stock may be reissued only as shares of any series of Preferred Stock other than Designated Preferred Stock).

Upon

7


any termination of the right of the holders of shares of Designated Preferred Stock and Voting Parity Stock as a class to vote for directors as provided above, the Preferred Directors shall cease to be qualified as directors, the term of office of all Preferred Directors then in office shall terminate immediately and the authorized number of directors shall be reduced by the number of Preferred Directors elected pursuant hereto.

provided , however , that for all purposes of this Section 7(c), any increase in the amount of the authorized Preferred Stock, including any increase in the authorized amount of Designated Preferred Stock necessary to satisfy preemptive or similar rights granted by the Corporation to other persons prior to the Signing Date, or the creation and issuance, or an increase in the authorized or issued amount, whether pursuant to preemptive or similar rights or otherwise, of any other series of Preferred Stock, or any securities convertible into or

exchangeable or exercisable for any other series of Preferred Stock, ranking equally with and/or junior to Designated Preferred Stock with respect to the payment of dividends (whether such dividends are cumulative or non-cumulative) and the distribution of assets upon liquidation, dissolution or winding up of the Corporation will not be deemed to adversely affect the rights, preferences, privileges or voting powers, and shall not require the affirmative vote or consent of, the holders of outstanding shares of the Designated Preferred Stock.
(d)      Changes after Provision for Redemption . No vote or consent of the holders of Designated Preferred Stock shall be required pursuant to Section 7(c) above if, at or prior to the time when any such vote or consent would otherwise be required pursuant to such Section, all outstanding shares of the Designated Preferred Stock shall have been redeemed, or shall have been called for redemption upon proper notice and sufficient funds shall have been deposited in trust for such redemption, in each case pursuant to Section 5 above.

(ll) “ Widely Dispersed Offering ” means (a) a widespread public distribution, including pursuant to Rule 144 under the Securities Act of 1933, as amended, (b) a transfer in which no transferee (or group of associated transferees) would receive more than 2% of any class of Voting Securities of the Corporation or (c) a transfer to a transferee that would control more than 50% of the Voting Securities of the Corporation without any transfer from the transferor.
Section 2. Designation and Number of Shares. There is hereby created out of the authorized and unissued shares of preferred stock of the Corporation a series of preferred stock designated as the “Mandatorily Convertible

3


Cumulative Participating Preferred Stock, Series B” (the “ Series B Preferred Stock ”). The number of shares constituting such series shall be 8,782. The Series B Preferred Stock shall have no par value.
Section 3. Ranking . The Series B Preferred Stock will, with respect to dividend rights and rights on liquidation, winding-up and dissolution, rank (i) on a parity with Series A Preferred Stock and each other class or series of equity securities of the Corporation, if any, the terms of which do not expressly provide that such class or series will rank senior or junior to the Series B Preferred Stock as to dividend rights and rights on liquidation, winding-up and dissolution of the Corporation (collectively referred to as “ Parity Securities ”), and (ii) senior to the Corporation’s common stock, no par value (the “ Common Stock ”) and each other class or series of capital stock outstanding or established after the Effective Date by the Corporation the terms of which expressly provide that it ranks junior to the Series B Preferred Stock as to dividend rights and/or as to rights on liquidation, winding-up and dissolution of the Corporation (collectively referred to as “ Junior Securities ”). The Corporation has the right to authorize and/or issue additional shares or classes or series of Junior Securities or Parity Securities without the consent of the Holders.
Section 4. Dividends.
(a) From and after the Effective Date, Holders shall be entitled to receive, when, as and if declared by the Board of Directors, out of the funds legally available therefor, dividends in the amount determined as set forth in Section 4(b)(i), and no more. Except as otherwise provided herein, such dividends shall be payable quarterly in arrears (as provided below in this Section 4(a)), but only when, as and if declared by the Board of Directors, on a “Dividend Payment Date”, commencing on June 15, 2013; provided that if any such Dividend Payment Date would otherwise occur on a day that is not a Business Day, such Dividend Payment Date shall instead be (and any dividend payable on Series B Preferred Stock on such Dividend Payment Date shall instead be payable on) the immediately succeeding Business Day, unless such immediately succeeding Business Day falls in the next calendar month, in which case such Dividend Payment Date shall instead be (and any such dividend shall instead be payable on) the immediately preceding Business Day.
Dividends on Series B Preferred Stock shall accrue at any time that dividends on the Series B Preferred Stock are cumulative (whether or not in any dividend period or periods (each, a “ Dividend Period ”) there shall be funds of the Corporation legally available for the payment of such dividends and whether or not such dividends are authorized or declared) and accrued dividends shall accumulate to the extent not paid on the Dividend Payment Date first following the Dividend Period for which they accrue. As used herein, the term “accrued” with respect to dividends includes both accrued and accumulated dividends. Dividends that are payable on Series B Preferred Stock on any Dividend Payment Date will be payable to holders of record of Series B Preferred Stock as they appear on the stock register of the Corporation on the applicable record date, which shall be the 15th calendar day immediately preceding such Dividend Payment Date or such other record date fixed by the Board of Directors or any duly authorized committee of the Board of Directors that is not more than 60 nor less than 10 days prior to such Dividend Payment Date (each, a “ Dividend Record Date ”). Any such day that is a Dividend Record Date shall be a Dividend Record Date whether or not such day is a Business Day.
Each Dividend Period shall commence on and include a Dividend Payment Date (other than the initial Dividend Period, which shall commence on and include the date of original issue of the Series B Preferred Stock, provided that, for any share of Series B Preferred Stock issued after such original issue date, the initial Dividend Period for such shares may commence on and include such other date as the Board of Directors or a duly authorized committee of the Board of Directors shall determine and publicly disclose) and shall end on and include the calendar day preceding the next Dividend Payment Date. Dividends that are payable on Series B Preferred Stock in respect of any Dividend Period shall be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of dividends payable on Series B Preferred Stock on any date prior to the end of a Dividend Period, and for the initial Dividend Period, shall be computed on the basis of a 360-day year consisting of twelve 30-day months, and actual days elapsed over a 30-day month.

(b) (i) Subject to Section 4(a), if the Board of Directors declares and pays a dividend or other distribution in respect of Common Stock (other than with respect to a 382 Rights Plan; provided that Holders of Series B Preferred Stock participate in such distribution under such 382 Rights Plan as if their shares of Series B Preferred Stock were converted into shares of Common Stock pursuant to Section 8 hereof), then the Board of Directors shall declare and pay to the Holders of the Series B Preferred Stock, on the same dates on which such dividend or other distribution is declared and paid on the Common Stock, a dividend or other distribution in an amount per share of Series B Preferred Stock equal to the product of (x) the per share dividend or other distribution declared and paid in respect of each share of Common Stock and (y) the number of shares of Common Stock into which such shares of Series B Preferred Stock is convertible as of the record date for such dividend or distribution.
(ii) Subject to Section 4(a), the dividend rate, and the rate at which dividends shall accrue, on each share of Series B Preferred Stock, for each Dividend Period, shall be at an annual rate equal to 15%, calculated with respect to the Base Value of a share of Series B Preferred Stock.
(c) Dividends in arrears on the Series B Preferred Stock in respect of a Dividend Period not declared for payment or to the extent not paid on the first Dividend Payment Date following the Dividend Period for which they accrue may be declared by the Board of Directors and paid on any date fixed by the Board of Directors, whether or not a Dividend Payment Date, to the holders of record of Series B Preferred Stock as they appear on the stock register of the Corporation on a record date selected by the Board of Directors, which shall (a) not precede the date the Board of Directors declares the dividend payable and (b) not be more than 60 days prior to the date the dividend is paid.
(d) So long as any share of Series B Preferred Stock remains outstanding, (1) no dividend or interest shall be declared and paid or set aside for payment and no distribution shall be declared and made or set aside for payment on any Junior Securities (other than a dividend payable solely in shares of Junior Securities) or trust preferred securities and (2) no shares of Junior Securities or trust preferred securities shall be purchased, redeemed or otherwise acquired by the Corporation, directly or indirectly. So long as any share of Series B Preferred Stock remains outstanding, the foregoing limitations shall not apply if full dividends on all outstanding shares of Series B Preferred Stock for the then-current dividend period have been paid in full or declared and a sum sufficient for the payment thereof set aside for all outstanding shares of Series B Preferred Stock. The foregoing limitations shall not apply (i) to redemptions, purchases or other acquisitions of shares of Junior Securities in connection with any benefit plan or other similar arrangement with or for the benefit of any one or more employees, officers, directors or consultants or in connection with a dividend reinvestment or shareholder stock purchase plan; (ii) to any declaration of a dividend in connection with any shareholders’ rights plan, or the issuance of rights, stock or other property under any shareholders’ rights plan, or the redemption or repurchase of rights pursuant thereto; and (iii) to conversions into or exchanges for other Junior Securities and cash solely in lieu of fractional shares of the Junior Securities.
(e) So long as any shares of Series B Preferred Stock remain outstanding, no dividends shall be declared or paid or set aside for payment on any Parity Securities for any period (other than with respect to a 382 Rights Plan) unless full dividends on all outstanding shares of Series B Preferred Stock for the then-current dividend period have been paid in full or declared and a sum sufficient for the payment thereof set aside for all outstanding shares of Series B Preferred Stock. To the extent the Corporation declares dividends on the Series B Preferred Stock and on any Parity Securities but does not make full payment of such declared dividends, the Corporation shall allocate the dividend payments on a pro rata basis among the holders of the shares of Series B Preferred Stock and the holders of any Parity Securities then outstanding. For purposes of calculating the pro rata allocation of partial dividend payments, the Corporation shall allocate those payments so that the respective amounts of those payments bear the same ratio to each other as all accrued and unpaid dividends per share on the Series B Preferred Stock and all Parity Securities bear to each other.
(f) At any time that dividends on the Series B Preferred Stock are not cumulative, and if a Conversion Date with respect to any share of Series B Preferred Stock is prior to the record date for the payment of any dividend

5


on the Common Stock, the Holder of such share of Series B Preferred Stock will not have the right to receive any corresponding dividends on the Series B Preferred Stock. At any time that dividends on the Series B Preferred Stock are not cumulative, and if the Conversion Date with respect to any share of Series B Preferred Stock is after the Dividend Record Date for any declared dividend and prior to the payment date for that dividend, the Holder thereof shall receive that dividend on the relevant payment date if such Holder was the Holder of record on the Dividend Record Date for that dividend. Any accrued and unpaid cumulative dividends on the Series B Preferred Stock shall be payable in cash on the Conversion Date.
Section 5. Liquidation.
(a) In the event the Corporation voluntarily or involuntarily liquidates, dissolves or winds up, the Holders at the time shall be entitled to receive, for each share of the Series B Preferred Stock, the sum of (i) liquidating distributions in an amount equal to the Liquidation Preference, plus any accrued but unpaid dividends thereon to and including the date of such liquidation, out of assets legally available for distribution to the Corporation’s shareholders, before any distribution of assets is made to the holders of the Common Stock or any other Junior Securities and (ii) after all distributions have been made to Holders pursuant to clause (i) of this sentence, liquidating distributions, as determined by the Corporation (or the trustee or other Person or Persons administering its liquidation, dissolution or winding-up in accordance with applicable law) as of a date that is at least ten (10) Business Days before the first liquidating distribution is made on Series B Preferred Stock, that would be made on the number of shares of Common Stock equal to the Base Value divided by the Applicable Conversion Price as if all of the outstanding shares of Series B Preferred Stock had been converted into Common Stock on such date of determination, out of assets legally available for distribution to the Corporation’s shareholders, simultaneous with any distribution of assets made to the holders of the Common Stock. The Corporation shall notify each Holder of the amount it has calculated pursuant to this Section 5 by first-class mail, postage prepaid, addressed to the Holders at their respective last addresses appearing on the books of the Corporation. Such mailing shall be made not later than five Business Days before the first liquidating distribution is made on shares of Series B Preferred Stock.
(b) In the event the assets of the Corporation available for distribution to shareholders upon any liquidation, dissolution or winding-up of the affairs of the Corporation, whether voluntary or involuntary, shall be insufficient to pay in full the amounts payable with respect to all outstanding shares of the Series B Preferred Stock and the corresponding amounts payable on any Parity Securities, Holders and the holders of such Parity Securities shall share ratably in any distribution of assets of the Corporation in proportion to the full respective liquidating distributions to which they would otherwise be respectively entitled.
(c) For purposes of this Section 5, the Corporation’s consolidation or merger with or into any other entity, the consolidation or merger of any other entity with or into the Corporation, or the sale of all or substantially all of the Corporation’s property or business will not constitute a liquidation, dissolution or winding-up of the Corporation.
Section 6. Maturity . The Series B Preferred Stock shall be perpetual unless converted in accordance with this Articles of Amendment.
Section 7. Redemptions .
(a) Redemption . The shares of Series B Preferred Stock are not redeemable by the Corporation.
(b) No Sinking Fund . The Series B Preferred Stock will not be subject to any mandatory redemption, sinking fund or other similar provisions.
Section 8. Conversion .
(a) Effective as of the close of business on the Mandatory Conversion Date with respect to the shares of Series B Preferred Stock of a Holder, such Holder’s shares of Series B Preferred Stock shall automatically convert into shares of Common Stock as set forth below. The number of shares of Common Stock into which

6


a share of Series B Preferred Stock shall be convertible shall be determined by dividing the Base Value by the Applicable Conversion Price (subject to the conversion procedures of Section 9 hereof), provided that cash will be paid in lieu of fractional shares in accordance with Section 13 hereof.
(b) Notwithstanding anything herein to the contrary, in no event shall a transferee of a Widely Disbursed Offering be entitled to receive shares of Common Stock upon any conversion of Series B Preferred Stock pursuant to this Section 8 or Section 11 to the extent (but only to the extent) that at such time the transferee Holder does not have any required Regulatory Approvals. If any delivery of shares of Common Stock owed to a transferee upon conversion of Series B Preferred Stock is not made, in whole or in part, as a result of the foregoing limitations, the Corporation’s obligation to make such delivery shall not be extinguished and the Corporation shall, at the option of the transferee Holder, deliver such shares as promptly as practicable after such converting Holder gives notice to the Corporation that the requirements of this Section 8(b) are met.
Section 9. Conversion Procedures .
(a) Each Holder shall promptly provide written notice to the Corporation of its intent to transfer its Series B Preferred Stock in a Widely Dispersed Offering and, promptly upon receipt of each required Regulatory Approval applicable to the transferee, such transferee shall provide written notice to the Corporation of such receipt. Upon occurrence of the Mandatory Conversion Date with respect to shares of any Holder, the Corporation shall provide notice of such conversion to such Holder (such notice a “ Notice of Mandatory Conversion ”). In addition to any information required by applicable law or regulation, the Notice of Mandatory Conversion with respect to such Holder shall state, as appropriate:
(i) the Mandatory Conversion Date applicable to such Holder;
(ii) the number of shares of Common Stock to be issued upon conversion of each share of Series B Preferred Stock held of record by such Holder and subject to such mandatory conversion; and
(iii) the place or places where certificates for shares of Series B Preferred Stock held of record by such Holder are to be surrendered for issuance of certificates representing shares of Common Stock.
(b) In the event that such Holder fails to surrender the required certificates for shares of Series B Preferred Stock held of record by such Holder within 30 days after delivery of the Mandatory Conversion Date, the Corporation shall, by written notice to such Holder, indicate which shares have been converted pursuant to Section 8.
(c) Effective immediately prior to the close of business on any Conversion Date with respect to any share of Series B Preferred Stock, dividends shall no longer be declared on any such converted share of Series B Preferred Stock and such share of Series B Preferred Stock shall cease to be outstanding, in each case, subject to the right of the Holder to receive any accrued and unpaid or declared and unpaid dividends on such share to the extent provided in Section 4(f) and any other payments to which such Holder is otherwise entitled pursuant to Section 8, Section 11 or Section 13 hereof, as applicable.
(d) No allowance or adjustment, except pursuant to Section 10, shall be made in respect of dividends payable to holders of the Common Stock of record as of any date prior to the close of business on any Conversion Date with respect to any share of Series B Preferred Stock. Prior to the close of business on the Conversion Date with respect to any share of Series B Preferred Stock, shares of Common Stock issuable upon conversion thereof, or other securities issuable upon conversion of, such share of Series B Preferred Stock shall not be deemed outstanding for any purpose, and the Holder thereof shall have no rights with respect to the Common Stock or other securities issuable upon conversion (including voting rights, rights to respond to tender offers for the Common Stock or other securities issuable upon conversion and rights to receive any dividends or other distributions on the Common Stock or other securities issuable upon conversion) by virtue of holding such share of Series B Preferred Stock.
(e) Shares of Series B Preferred Stock duly converted in accordance with Section 8 or Section 11 of this Articles of Amendment will resume the status of authorized and unissued preferred stock, undesignated as to series and available for future issuance. The Corporation may, from time to time, take such appropriate action as may be necessary to reduce the authorized number of shares of Series B Preferred Stock; provided , however ,

7


that the Corporation shall not take any such action if such action would reduce the authorized number of shares of Series B Preferred Stock below the sum of (i) the number of shares of Series B Preferred Stock then outstanding and (ii) the number of shares of Series B Preferred Stock issuable upon the exercise of any warrants then outstanding.
(f) The Person or Persons entitled to receive the Common Stock and/or cash, securities or other property issuable upon conversion of Series B Preferred Stock shall be treated for all purposes as the record holder(s) of such shares of Common Stock and/or securities as of the close of business on the applicable Conversion Date with respect thereto. In the event that a Holder shall not by written notice designate the name in which shares of Common Stock and/or cash, securities or other property (including payments of cash in lieu of fractional shares) to be issued or paid upon conversion of shares of Series B Preferred Stock should be registered or paid or the manner in which such shares should be delivered, the Corporation shall be entitled to register and deliver such shares, and make such payment, in the name of the Holder and in the manner shown on the records of the Corporation.
(g) On the Mandatory Conversion Date with respect to any share of Series B Preferred Stock, certificates representing shares of Common Stock shall be issued and delivered to the Holder thereof or such Holder’s designee upon presentation and surrender of the certificate evidencing the Series B Preferred Stock to the Corporation and, if required, the furnishing of appropriate endorsements and transfer documents and the payment of all transfer and similar taxes.
Section 10. Anti-Dilution Adjustments .
(a) The Conversion Price shall be subject to the following adjustments.
(i) Stock Dividends and Distributions . If the Corporation pays dividends or other distributions on the Common Stock in shares of Common Stock, then the Conversion Price in effect immediately prior to the Ex-Date for such dividend or distribution will be multiplied by the following fraction:
OS 0
OS1
Where,
OS 0  =
 
the number of shares of Common Stock outstanding immediately prior to the Ex-Date for such dividend or distribution.
 
 
 
OS1 =
 
the sum of the number of shares of Common Stock outstanding immediately prior to the Ex-Date for such dividend or distribution plus the total number of shares of Common Stock constituting such dividend or distribution.
For the purposes of this clause (i), the number of shares of Common Stock at the time outstanding shall not include shares acquired by the Corporation. If any dividend or distribution described in this clause (i) is declared but not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to make such dividend or distribution, to such Conversion Price that would be in effect if such dividend or distribution had not been declared.
(ii) Subdivisions, Splits and Combination of the Common Stock . If the Corporation subdivides, splits or combines the shares of Common Stock, then the Conversion Price in effect immediately prior to the effective date of such share subdivision, split or combination will be multiplied by the following fraction:
OS 0
OS1
Where,

8


OS 0  =
 
the number of shares of Common Stock outstanding immediately prior to the effective date of such share subdivision, split or combination.
 
 
 
OS1 =
 
the number of shares of Common Stock outstanding immediately after the opening of business on the effective date of such share subdivision, split or combination.
For the purposes of this clause (ii), the number of shares of Common Stock at the time outstanding shall not include shares acquired by the Corporation. If any subdivision, split or combination described in this clause (ii) is announced but the outstanding shares of Common Stock are not subdivided, split or combined, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to subdivide, split or combine the outstanding shares of Common Stock, to such Conversion Price that would be in effect if such subdivision, split or combination had not been announced.
(iii) Issuance of Stock Purchase Rights . If the Corporation issues to all or substantially all holders of the shares of Common Stock rights or warrants (other than rights or warrants issued pursuant to a dividend reinvestment plan or share purchase plan or other similar plans) entitling them, for a period of up to 45 days from the date of issuance of such rights or warrants, to subscribe for or purchase the shares of Common Stock at less than the Current Market Price on the date fixed for the determination of shareholders entitled to receive such rights or warrants, then the Conversion Price in effect immediately prior to the Ex-Date for such distribution will be multiplied by the following fraction:
OS 0 + Y
OS 0 + X
Where,
OS 0  =
 
the number of shares of Common Stock outstanding immediately prior to the Ex-Date for such distribution.
 
 
 
X =
 
the total number of shares of Common Stock issuable pursuant to such rights or warrants.
 
 
 
Y =
 
the number of shares of Common Stock equal to the aggregate price payable to exercise such rights or warrants divided by the Current Market Price on the date fixed for the determination of shareholders entitled to receive such rights or warrants.
For the purposes of this clause (iii), the number of shares of Common Stock at the time outstanding shall not include shares acquired by the Corporation. In the event that such rights or warrants described in this clause (iii) are not so issued, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to issue such rights or warrants, to the Conversion Price that would then be in effect if such issuance had not been declared. To the extent that such rights or warrants are not exercised prior to their expiration or shares of Common Stock are otherwise not delivered pursuant to such rights or warrants upon the exercise of such rights or warrants, the Conversion Price shall be readjusted to such Conversion Price that would then be in effect had the adjustment made upon the issuance of such rights or warrants been made on the basis of the delivery of only the number of shares of Common Stock actually delivered. In determining the aggregate offering price payable for such shares of Common Stock, there shall be taken into account any consideration received for such rights or warrants and the value of such consideration (if other than cash, to be determined by the Board of Directors).
(iv) Debt or Asset Distributions . If the Corporation distributes to all or substantially all holders of shares of Common Stock evidences of indebtedness, shares of capital stock, securities, cash or other assets (excluding any dividend or distribution referred to in clause (i) above, any rights or warrants referred to in clause (iii) above, any dividend or distribution paid exclusively in cash, any consideration payable in connection with a tender or

9


exchange offer made by the Corporation or any of its subsidiaries, and any dividend of shares of capital stock of any class or series, or similar equity interests, of or relating to a subsidiary or other business unit in the case of certain spin-off transactions as described below), then the Conversion Price in effect immediately prior to the Ex-Date for such distribution will be multiplied by the following fraction:
SP 0 – FMV
SP 0
Where,
SP 0  =
 
the Current Market Price per share of Common Stock on the Trading Day immediately preceding the Ex-Date.
 
 
 
FMV =
 
the fair market value of the portion of the distribution applicable to one share of Common Stock on such date as determined by the Board of Directors, provided that, if “FMV” as set forth above is equal to or greater than “SP 0 ” as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall receive on the date on which such distribution is made to holders of Common Stock, for each share of Preferred Stock, the amount of such distribution such Holder would have received had such holder owned a number of shares of Common Stock equal to the Base Value divided by the Applicable Conversion Price on the Ex-Date for such distribution.
In a “spin-off”, where the Corporation makes a distribution to all holders of shares of Common Stock consisting of capital stock of any class or series, or similar equity interests of, or relating to, a subsidiary or other business unit, the Conversion Price will be adjusted on the 15th Trading Day after the effective date of the distribution by multiplying such Conversion Price in effect immediately prior to such 15th Trading Day by the following fraction:
MP 0
MP 0 + MP S

Where,
MP 0  =
 
the average of the Closing Prices of the Common Stock over the first ten Trading Days commencing on and including the fifth Trading Day following the effective date of such distribution.
 
 
 
MP S  =
 
the average of the Closing Prices of the capital stock or equity interests representing the portion of the distribution applicable to one share of Common Stock over the first ten Trading Days commencing on and including the fifth Trading Day following the effective date of such distribution, or, if not traded on a national or regional securities exchange or over-the-counter market, the fair market value of the capital stock or equity interests representing the portion of the distribution applicable to one share of Common Stock on such date as determined by the Board of Directors.
In the event that such distribution described in this clause (iv) is not so paid or made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay or make such dividend or distribution, to the Conversion Price that would then be in effect if such dividend or distribution had not been declared.
(v) Cash Distributions . If the Corporation makes a distribution consisting exclusively of cash to all holders of the Common Stock, excluding (a) any cash dividend on the Common Stock to the extent a corresponding cash dividend is paid on the Series B Preferred Stock pursuant to Section 4(b), (b) any cash that is distributed in a Reorganization Event or as part of a “spin-off” referred to in clause (iv) above, (c) any dividend

10


or distribution in connection with the Corporation’s liquidation, dissolution or winding-up, and (d) any consideration payable in connection with a tender or exchange offer made by the Corporation or any of its subsidiaries, then in each event, the Conversion Price in effect immediately prior to the Ex-Date for such distribution will be multiplied by the following fraction:
SP 0 – DIV
SP 0
Where,
SP 0  =
 
the Closing Price per share of Common Stock on the Trading Day immediately preceding the Ex-Date.
 
 
 
DIV =
 
the amount per share of Common Stock of the cash distribution, as determined pursuant to the introduction to this paragraph (v).
In the event that any distribution described in this clause (v) is not so made, the Conversion Price shall be readjusted, effective as of the date the Board of Directors publicly announces its decision not to pay such distribution, to the Conversion Price which would then be in effect if such distribution had not been declared.
Notwithstanding the foregoing, if “DIV” as set forth above is equal to or greater than “SP 0 ” as set forth above, in lieu of the foregoing adjustment, adequate provision shall be made so that each Holder shall have the right to receive on the date on which the relevant cash dividend or distribution is distributed to holders of Common Stock, for each share of Preferred Stock, the amount of cash such Holder would have received had such Holder owned a number of shares of Common Stock equal to the Base Value divided by the Applicable Conversion Price on the Ex-Date for such distribution.
(vi) Self Tender Offers and Exchange Offers . If the Corporation or any of its subsidiaries successfully completes a tender or exchange offer for the Common Stock where the cash and the value of any other consideration included in the payment per share of the Common Stock exceeds the Closing Price per share of the Common Stock on the Trading Day immediately succeeding the expiration of the tender or exchange offer, then the Conversion Price in effect at the close of business on such immediately succeeding Trading Day will be multiplied by the following fraction:
OS 0 x SP 0
AC + (SP 0 x OS1)
Where,
SP 0  =
 
the Closing Price per share of Common Stock on the Trading Day immediately succeeding the expiration of the tender or exchange offer.
 
 
 
OS 0  =
 
the number of shares of Common Stock outstanding immediately prior to the expiration of the tender or exchange offer, including any shares validly tendered and not withdrawn.
 
 
 
OS1 =
 
the number of shares of Common Stock outstanding immediately after the expiration of the tender or exchange offer.
 
 
 
AC =
 
the aggregate cash and fair market value of the other consideration payable in the tender or exchange offer, as determined by the Board of Directors.
In the event that the Corporation, or one of its subsidiaries, is obligated to purchase shares of Common Stock pursuant to any such tender offer or exchange offer, but the Corporation, or such subsidiary, is permanently

11


prevented by applicable law from effecting any such purchases, or all such purchases are rescinded, then the Conversion Price shall be readjusted to be such Conversion Price that would then be in effect if such tender offer or exchange offer had not been made.
(vii) Rights Plans . To the extent that the Corporation has a rights plan in effect with respect to the Common Stock on the Mandatory Conversion Date, upon conversion of any shares of the Series B Preferred Stock, Holders will receive, in addition to the shares of Common Stock, the rights under the rights plan, unless, prior to the Mandatory Conversion Date, the rights have separated from the shares of Common Stock, in which case the Conversion Price will be adjusted at the time of separation as if the Corporation had made a distribution to all holders of the Common Stock as described in clause (iv) above, subject to readjustment in the event of the expiration, termination or redemption of such rights.
(b) The Corporation may make such decreases in the Conversion Price, in addition to any other decreases required by this Section 10, if the Board of Directors deems it advisable to avoid or diminish any income tax to holders of the Common Stock resulting from any dividend or distribution of shares of Common Stock (or issuance of rights or warrants to acquire shares of Common Stock) or from any event treated as such for income tax purposes or for any other reason.
(c) (i) All adjustments to the Conversion Price shall be calculated to the nearest 1/10 of a cent. No adjustment in the Conversion Price shall be required if such adjustment would be less than $0.01; provided that any adjustments which by reason of this subparagraph are not required to be made shall be carried forward and taken into account in any subsequent adjustment; provided further that on the Mandatory Conversion Date adjustments to the Conversion Price will be made with respect to any such adjustment carried forward and which has not been taken into account before such date.
(ii) No adjustment to the Conversion Price shall be made if Holders may participate in the transaction that would otherwise give rise to an adjustment, as a result of holding the Series B Preferred Stock (including without limitation pursuant to Section 4(b) hereof), without having to convert the Series B Preferred Stock, as if they held the full number of shares of Common Stock into which a share of the Series B Preferred Stock may then be converted. No single event shall be subject to adjustment under more than one subsection of this Section 10 so as to result in duplication.
(iii) The Applicable Conversion Price shall not be adjusted:
(A) with respect to a 382 Rights Plan; provided that Holders of Series B Preferred Stock participate in such distribution under such 382 Rights Plan as if their shares of Series B Preferred Stock were converted into shares of Common Stock pursuant to Section 8 hereof;
(B) upon the issuance of any shares of Common Stock pursuant to any present or future plan providing for the reinvestment of dividends or interest payable on the Corporation’s securities and the investment of additional optional amounts in shares of Common Stock under any such plan;
(C) upon the issuance of any shares of Common Stock or rights or warrants to purchase those shares pursuant to any present or future employee, director or consultant benefit plan or program of or assumed by the Corporation or any of its subsidiaries;
(D) upon the issuance of any shares of Common Stock pursuant to any option, warrant, right or exercisable, exchangeable or convertible security outstanding as of the date shares of the Series B Preferred Stock were first issued and not substantially amended thereafter;
(E) for a change in the par value or no par value of Common Stock; or
(F) for accrued and unpaid dividends on the Series B Preferred Stock.
(d) Whenever the Conversion Price is to be adjusted in accordance with Section 10(a) or Section 10(b), the Corporation shall: (i) compute the Conversion Price in accordance with Section 10(a) or Section 10(b), taking into account the one cent threshold set forth in Section 10(c) hereof; (ii) as soon as practicable following the occurrence of an event that requires an adjustment to the Conversion Price pursuant to Section 10(a) or Section 10(b), taking into account the one percent threshold set forth in Section 10(c) hereof (or if the Corporation is

12


not aware of such occurrence, as soon as practicable after becoming so aware), provide, or cause to be provided, a written notice to the Holders of the occurrence of such event; and (iii) as soon as practicable following the determination of the revised Conversion Price in accordance with Section 10(a) or Section 10(b) hereof, provide, or cause to be provided, a written notice to the Holders setting forth in reasonable detail the method by which the adjustment to the Conversion Price was determined and setting forth the revised Conversion Price.
Section 11. Reorganization Events .
(a) In the event that, prior to the Mandatory Conversion Date with respect to the shares of Series B Preferred Stock of any Holder, there occurs:
(i) any consolidation, merger or other similar business combination of the Corporation with or into another Person, in each case pursuant to which the Common Stock will be converted into cash, securities or other property of the Corporation or another Person;
(ii) any sale, transfer, lease or conveyance to another Person of all or substantially all of the property and assets of the Corporation, in each case pursuant to which the Common Stock will be converted into cash, securities or other property of the Corporation or another Person;
(iii) any reclassification of the Common Stock into securities including securities other than the Common Stock; or
(iv) any statutory exchange of the outstanding shares of Common Stock for securities of another Person (other than in connection with a merger or acquisition);
(any such event specified in this Section 11(a), a “ Reorganization Event ”) then, subject to Section 8(b), each share of such Holder’s Series B Preferred Stock outstanding immediately prior to such Reorganization Event shall remain outstanding but each Holder shall have the right, at its option, subject to the terms and provisions of this Section 11, to convert any or all of such Holder’s shares of Series B Preferred Stock, effective as of the close of business on the Reorganization Conversion Date (with the term “Regulatory Approval” applied for such purpose, as applicable, to the surviving entity in such Reorganization Event and its securities included in the Exchange Property (as defined below)), into the type and amount of securities, cash and other property receivable in such Reorganization Event by the Holder (other than a counterparty to the Reorganization Event or an Affiliate of such counterparty) in respect of each such share of Series B Preferred Stock equal to the number of shares of Common Stock into which one share of Series B Preferred Stock would then be convertible assuming that a Mandatory Conversion Date in respect of such shares of Series B Preferred Stock had occurred (such securities, cash and other property, the “ Exchange Property ”).
(b) The conversion right of a Holder of Series B Preferred Stock pursuant to this Section 11 shall be exercised by the Holder by the surrender of the certificates representing the shares to be converted to the Corporation or to the transfer agent for the Corporation, accompanied by a notice of reorganization conversion, no later than the tenth day following the date of delivery to each Holder of a notice from the Corporation of the expected consummation or the consummation of a Reorganization Event.
(i) Immediately prior to the close of business on the Reorganization Conversion Date, each converting Holder of Series B Preferred Stock shall be deemed to be the Holder of record of the number of shares of Common Stock deemed to be issuable upon conversion of such Holder’s Series B Preferred Stock in accordance with clause (i) or (ii) of Section 11(a), notwithstanding that the share register of the Corporation shall then be closed or that certificates representing such Common Stock shall not then be actually delivered to such Person.

13


(ii) Upon notice from the Corporation, each Holder of Series B Preferred Stock so converted shall promptly surrender to the Corporation or its transfer agent certificates representing the shares so converted (if not previously delivered), duly endorsed in blank or accompanied by proper instruments of transfer.
(c) In the event that holders of the shares of Common Stock have the opportunity to elect the form of consideration to be received in connection with any Reorganization Event, the Holders shall be entitled to the same right of election as holders of the shares of Common Stock with respect to the form of consideration to be received pursuant to this Section 11.
(d) The above provisions of this Section 11 shall similarly apply to successive Reorganization Events and the provisions of Section 10 shall apply to any shares of capital stock of the Corporation (or any successor) received by the holders of the Common Stock in any such Reorganization Event.
(e) The Corporation (or any successor) shall, within seven days of the consummation of any Reorganization Event, provide written notice to the Holders of such consummation of such event and of the kind and amount of the cash, securities or other property that constitutes the Exchange Property. Failure to deliver such notice shall not affect the operation of this Section 11.
(f) The Corporation shall not enter into any agreement for a transaction constituting a Reorganization Event unless such agreement provides for or does not interfere with or prevent (as applicable) conversion of the Series B Preferred Stock into the Exchange Property in a manner that is consistent with and gives effect to this Section 11.
Section 12. Voting Rights .
(a) Holders will not have any voting rights, including the right to elect any directors, except (i) voting rights, if any, required by law, and (ii) voting rights, if any, described in this Section 12.
(b) So long as any shares of Series B Preferred Stock are outstanding, the vote or consent of the Holders of three-quarters of the shares of Series B Preferred Stock at the time outstanding voting as a single class with all other classes and series of Parity Securities having similar voting rights then outstanding, given in person or by proxy, either in writing without a meeting or by vote at any meeting called for the purpose, will be necessary for effecting or validating, whether or not such approval is required by Washington law:
(i) any amendment or alteration (including by means of a merger, consolidation or otherwise) of the Articles of Incorporation to authorize or create, or increase the authorized amount of, any shares of, or any securities convertible into shares of, any class or series of the Corporation’s capital stock ranking prior to the Series B Preferred Stock in the payment of dividends or in the distribution of assets on any liquidation, dissolution or winding-up of the Corporation;
(ii) any amendment, alteration or repeal (including by means of a merger, consolidation or otherwise) of any provision of the Articles of Incorporation (including this Articles of Amendment) or the Bylaws that would significantly and adversely alter or change the terms, rights, preferences or privileges of the Series B Preferred Stock; or
(iii) the consummation of a binding share exchange or reclassification involving the Series B Preferred Stock or a merger or consolidation of the Corporation with another entity;
provided , however, that a Holder will have no right to vote under this provision or under Washington law if such voting rights arise due to a Reorganization Event if (1) the Corporation shall have complied with Section 11(f) or (2) in each case (a) the Series B Preferred Stock remains outstanding or, in the case of any merger or consolidation with respect to which the Corporation is not the surviving or resulting entity, is converted into or exchanged for preference securities of the surviving or resulting entity or its ultimate parent, that is an entity organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, and (b) such Series B Preferred Stock remaining outstanding or such preference securities, as the

14


case may be, have such rights (including, but not limited to, the right of conversion), preferences, privileges and voting powers that, taken as a whole, as are not materially less favorable to the Holders thereof than the rights, preferences, privileges and voting powers of the Series B Preferred Stock, taken as a whole, immediately prior to the Reorganization Event; provided further , that any increase in the amount of the authorized Preferred Stock or any securities convertible into Preferred Stock or the creation and issuance, or an increase in the authorized or issued amount, of any series of Preferred Stock or any securities convertible into preferred stock ranking equally with and/or junior to the Series B Preferred Stock with respect to the payment of dividends (whether such dividends are cumulative or non-cumulative) and/or the distribution of assets upon the Corporation’s liquidation, dissolution or winding-up will not, in and of itself, be deemed to affect the voting powers, preferences or special rights of the Series B Preferred Stock and, notwithstanding any provision of Washington law, Holders will have no right to vote solely by reason of such an increase, creation or issuance.
Each holder of Series B Preferred Stock will have one vote per share on any matter on which holders of Series B Preferred Stock are entitled to vote, including any action by written consent.
If an amendment, alteration, repeal, share exchange, reclassification, merger or consolidation described above would adversely affect one or more but not all series of Preferred Stock with like voting rights (including the Series B Preferred Stock for this purpose), then only the series affected and entitled to vote shall vote as a class in lieu of all such series of Preferred Stock.
(c) Notwithstanding the foregoing, Holders shall not have any voting rights if, at or prior to the effective time of the act with respect to which such vote would otherwise be required, all outstanding shares of Series B Preferred Stock shall have been converted into shares of Common Stock.
Section 13. Fractional Shares .
(a) No fractional shares of Common Stock will be issued as a result of any conversion of shares of Series B Preferred Stock.
(b) In lieu of any fractional share of Common Stock otherwise issuable in respect of any mandatory conversion pursuant to Section 8 hereof, the Corporation shall pay an amount in cash (computed to the nearest cent) equal to the same fraction of the Closing Price of the Common Stock determined as of the second Trading Day immediately preceding the Mandatory Conversion Date.
(c) If more than one share of the Series B Preferred Stock is surrendered for conversion at one time by or for the same Holder, the number of full shares of Common Stock issuable upon conversion thereof shall be computed on the basis of the aggregate number of shares of the Series B Preferred Stock so surrendered.
Section 14. Reservation of Common Stock.
(a) The Corporation shall at all times thereafter reserve and keep available out of its authorized and unissued Common Stock or shares acquired by the Corporation, solely for issuance upon the conversion of shares of Series B Preferred Stock as provided in this Articles of Amendment, free from any preemptive or other similar rights, such number of shares of Common Stock as shall from time to time be issuable upon the conversion of all the shares of Series B Preferred Stock then outstanding, assuming that the Applicable Conversion Price equaled the Base Price.
(b) Notwithstanding the foregoing, the Corporation shall be entitled to deliver upon conversion of shares of Series B Preferred Stock, as herein provided, shares of Common Stock acquired by the Corporation (in lieu of the issuance of authorized and unissued shares of Common Stock), so long as any such acquired shares are free and clear of all liens, charges, security interests or encumbrances (other than liens, charges, security interests and other encumbrances created by the Holders).
(c) All shares of Common Stock delivered upon conversion of the Series B Preferred Stock shall be duly authorized, validly issued, fully paid and non-assessable, free and clear of all liens, claims, security interests

15


and other encumbrances (other than liens, charges, security interests and other encumbrances created by the Holders).
(d) Prior to the delivery of any securities that the Corporation shall be obligated to deliver upon conversion of the Series B Preferred Stock, the Corporation shall use its reasonable best efforts to comply with all federal and state laws and regulations thereunder requiring the registration of such securities with, or any approval of or consent to the delivery thereof by, any governmental authority.
(e) The Corporation hereby covenants and agrees that, if at any time the Common Stock shall be listed on the NASDAQ Stock Market or any other national securities exchange or automated quotation system, the Corporation will, if permitted by the rules of such exchange or automated quotation system, list and keep listed, so long as the Common Stock shall be so listed on such exchange or automated quotation system, all the Common Stock issuable upon conversion of the Series B Preferred Stock.
Section 15. Replacement Certificates . The Corporation shall replace any mutilated certificate at the Holder’s expense upon surrender of that certificate to the Corporation. The Corporation shall replace certificates that become destroyed, stolen or lost at the Holder’s expense upon delivery to the Corporation of satisfactory evidence that the certificate has been destroyed, stolen or lost, together with any indemnity that may be required by the Corporation.
Section 16. Miscellaneous .
(a) All notices or communications in respect of Series B Preferred Stock shall be sufficiently given if given in writing and delivered in person or by first class mail, postage prepaid, or if given in such other manner as may be permitted in this Certificate of Designations, in the Articles of Incorporation or Bylaws or by applicable law. Notwithstanding the foregoing, if shares of Series B Preferred Stock are issued in book-entry form through The Depository Trust Corporation or any similar facility, such notices may be given to the holders of Series B Preferred Stock in any manner permitted by such facility.
(b) The Corporation shall pay any and all stock transfer and documentary stamp taxes that may be payable in respect of any issuance or delivery of shares of Series B Preferred Stock or shares of Common Stock or other securities issued on account of Series B Preferred Stock pursuant hereto or certificates representing such shares or securities. The Corporation shall not, however, be required to pay any such tax that may be payable in respect of any transfer involved in the issuance or delivery of shares of Series B Preferred Stock or Common Stock or other securities in a name other than that in which the shares of Series B Preferred Stock with respect to which such shares or other securities are issued or delivered were registered, or in respect of any payment to any Person other than a payment to the registered holder thereof, and shall not be required to make any such issuance, delivery or payment unless and until the Person otherwise entitled to such issuance, delivery or payment has paid to the Corporation the amount of any such tax or has established, to the satisfaction of the Corporation, that such tax has been paid or is not payable.
(c) No share of Series B Preferred Stock shall have any rights of preemption whatsoever as to any securities of the Corporation, or any warrants, rights or options issued or granted with respect thereto, regardless of how such securities, or such warrants, rights or options, may be designated, issued or granted.
(d) The shares of Series B Preferred Stock shall not have any voting powers, preferences or relative, participating, optional or other special rights, or qualifications, limitations or restrictions thereof, other than as set forth herein or in the Articles of Incorporation or as provided by applicable law.
