COLUMBIA BANCORP AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation

The interim consolidated financial statements include the accounts of Columbia Bancorp (“Columbia” or the “Company”), an Oregon corporation and a registered financial holding company, and its wholly-owned subsidiary Columbia River Bank (“CRB” or the “Bank”), after elimination of intercompany transactions and balances. CRB is an Oregon state-chartered bank, headquartered in The Dalles. Substantially all activity of Columbia is conducted through its subsidiary bank, CRB.

The interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. The financial information included in this interim report has been prepared by Management. Columbia’s annual report contains audited financial statements. All adjustments, including normal recurring accruals necessary for the fair presentation of results of operations for the interim periods included herein, have been made. Certain amounts for 2006 have been reclassified to conform to the 2007 presentation. The results of operations for the three months ended March 31, 2007, are not necessarily indicative of results to be anticipated for the year ending December 31, 2007.

2. Management’s Estimates and Assumptions

Various elements of Columbia’s accounting policies are inherently subject to estimation techniques, valuation assumptions and other subjective assessments. In particular, Management has identified certain policies that due to the judgments, estimates and assumptions inherent in those policies are critical to an understanding of the consolidated financial statements. These policies and judgments, estimates and assumptions are described in greater detail in the notes to the consolidated financial statements included in Columbia’s annual report on Form 10-K, filed March 16, 2007.

Management believes the judgments, estimates and assumptions used in the preparation of the consolidated financial statements are appropriate given the factual circumstances at the time. However, given the sensitivity of the consolidated financial statements to these critical accounting policies, the use of other judgments, estimates and assumptions could result in material differences in the results of operations or financial conditions.

3. Loans and Allowance for Loan Losses

Loans are stated at the amount of unpaid principal, reduced by an allowance for loan losses and by unearned loan fees, net of deferred loan costs. Interest on loans is calculated using the simple-interest method on daily balances of the principal amount outstanding. Loan origination fees and certain direct origination costs are capitalized and recognized as an adjustment of the yield over the life of the related loan.

The Bank does not accrue interest on loans for which payment in full of principal and interest is not expected, or for which payment of principal or interest has been in default 90 days or more, unless the loan is well-secured and in the process of collection. Non-accrual loans are considered impaired loans. Each impaired loan is carried at the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s market price, or the fair value of collateral if the loan is collateral-dependent. When a loan is placed on non-accrual status, all unpaid accrued interest is reversed. Interest income is subsequently recognized only to the extent cash payments are received or when the loan is returned to accrual status. Large groups of smaller balance, homogeneous loans may be collectively evaluated for impairment. Accordingly, the Bank may not separately identify individual consumer and residential loans for evaluation of impairment.

7

Loans on non-accrual status as of March 31, 2007 and December 31, 2006, were $3.42 million and $4.94 million, respectively.

The allowance for loan losses represents an estimate of possible losses associated with the Bank’s loan portfolio and deposit account overdrafts. The estimate is based on evaluations of loan collectibility and prior loan loss experience. Evaluations consider factors such as changes in the nature and volume of the loan portfolio, overall portfolio quality, Management’s review of specific problem loans and current economic conditions that may affect a borrower’s ability to pay.

Increases to the allowance for loan losses occur when amounts are expensed to the provision for loan losses or when previously charged-off loans or overdrafts are recovered; decreases occur when loans or overdrafts are charged-off.

Various regulatory agencies, as a regular part of their examination process, periodically review the Bank’s allowance for loan losses. Such agencies may require the Bank to recognize additions to the allowance based on their judgment of information available to them at the time of the examinations.

4. Earnings Per Share

Basic earnings per share is computed by dividing net income available to shareholders by the weighted-average number of common shares outstanding during the period, after giving retroactive effect to stock dividends and splits. Diluted earnings per share is computed similar to basic earnings per share except the denominator is increased to include the number of additional common shares that would have been outstanding if dilutive potential common shares had been issued. Included in the denominator is the dilutive effect of stock options and awards computed by the treasury stock method.

5. Recently Issued Accounting Standards

In February 2006, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 155, “Accounting for Certain Hybrid Financial Instruments” which amends SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” and SFAS No. 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities.” SFAS No. 155 simplifies the accounting for certain derivatives embedded in other financial instruments by allowing them to be accounted for as a whole if the holder elects to account for the whole instrument on a fair value basis. SFAS No. 155 also clarifies and amends certain other provisions of SFAS No. 133 and SFAS No. 140. SFAS No. 155 is effective for all financial instruments acquired, issued or subject to a remeasurement event occurring in fiscal years beginning after September 15, 2006. Columbia’s adoption on January 1, 2007 did not have a material impact on the consolidated financial statements.

In March 2006, the FASB issued SFAS No. 156, “Accounting for Servicing of Financial Assets” which amends SFAS No. 140. SFAS No. 156 requires that all separately recognized servicing assets and servicing liabilities be initially measured at fair value, if practicable. The statement permits, but does not require, the subsequent measurement of servicing assets and servicing liabilities at fair value. SFAS No. 156 is effective for fiscal years beginning after September 15, 2006. Columbia’s adoption on January 1, 2007 did not have a material impact on the consolidated financial statements.

8

In June 2006, the FASB issued FASB Interpretation 48, “Accounting for Uncertainty in Income Taxes—an interpretation of FASB Statement No. 109. FIN 48 clarifies the accounting and reporting for income taxes where interpretation of the law is uncertain. FIN 48 prescribes a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of income tax uncertainties with respect to positions taken or expected to be taken in income tax returns. FIN 48 is effective for fiscal years beginning after December 15, 2006. Columbia adopted FIN 48 on January 1, 2007. As a result of the adoption, it was not necessary for Columbia to recognize any liability for unrecognized tax benefits.

Columbia and its subsidiary file income tax returns in the U.S. federal jurisdiction and in the State of Oregon jurisdictions. Columbia is no longer subject to U.S. federal and state examinations by tax authorities for years before 2003. Columbia recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” SFAS No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. The provisions of this standard apply to other accounting pronouncements that require or permit fair value measurements. SFAS No. 157 is effective for fiscal years beginning after November 15, 2007. Management does not expect the adoption of SFAS No. 157 to have a material impact on the consolidated financial statements.

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans.” SFAS No. 158 requires employers to recognize the funded status of defined benefit postretirement plans as a net asset or liability in its statement of financial position and to recognize changes in the funded status in the year in which the changes occur through accumulated other comprehensive income. SFAS No. 158 also requires employers to measure the funded status of a plan as of the date of its year-end statement of financial position. The new reporting requirements and related new footnote disclosure rules of SFAS No. 158 are effective for fiscal years ending after December 15, 2006. The new measurement date requirement applies for fiscal years ending after December 15, 2008. Management does not expect SFAS No.158 to have a material impact on the consolidated financial statements.

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities.” SFAS No. 159 permits companies to choose, at specified election dates, to measure eligible items at fair value. The standard is designed to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently. SFAS No. 159 is effective for fiscal years beginning after November 15, 2007, or if adopted early, within 120 days of the fiscal year of adoption. Management elected not to apply the early adoption provisions of the standard and is evaluating whether it will choose to apply the fair value option provided by SFAS No. 159.

6.    Subsequent Event

Subsequent to March 31, 2007, the Bank charged-off $2.10 million of an agricultural loan to a potato grower. As of March 31, 2007, the loan was on non-accrual status with a balance of $2.38 million. After the charge-off, the remaining loan balance totaled $278,000. In order to cover the write-down in excess of the specific reserve for this loan, the charge-off will result in a loan loss provision of $1.70 million during the three months ending June 30, 2007.

Forward-looking statements use prospective language, including words like “may,” “will,” “should,” “expect,” “anticipate,” “estimate,” “continue,” “plans,” “intends,” or other similar terminology.

Because forward-looking statements are, in part, an attempt to project future events and explain current plans, they are subject to various risks and uncertainties, which could cause our actions and our financial and operational results to differ materially from those projected in forward-looking statements. These risks and uncertainties include, without limitation, the risks described in Part II – Other Information Item 1A “Risk Factors.”

Information presented in this report is accurate as of the date the report is filed with the SEC. We do not undertake any duty to update our forward-looking statements or the factors that may cause us to deviate from them, except as required by law.

CRITICAL ACCOUNTING POLICIES

The “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” as well as disclosures included elsewhere in this Form 10-Q, are based upon consolidated financial statements which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires Management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an ongoing basis, Management evaluates the estimates used, including the adequacy of the allowance for loan losses, impairment of intangible assets, and contingencies and litigation. Estimates are based upon historical experience, current economic conditions and other factors that Management considers reasonable under the circumstances. These estimates result in judgments regarding the carrying values of assets and liabilities when these values are not readily available from other sources as well as assessing and identifying the accounting treatments of commitments and contingencies. Actual results may differ from these estimates under different assumptions or conditions. The following critical accounting policies involve the more significant judgments and assumptions used in the preparation of the consolidated financial statements.

The allowance for loan losses represents an estimate of possible losses associated with the Bank’s loan portfolio and deposit account overdrafts. On an ongoing basis, we evaluate the adequacy of the allowance based on numerous factors. These factors include the quality of the current loan portfolio, the trend in the loan portfolio’s risk ratings, current economic conditions, loan concentrations, loan growth rates, past-due and non-performing loan trends, evaluation of specific loss estimates for significant problem loans, historical charge-off and recovery experience and other pertinent information. Approximately 75% of our loan portfolio is secured by real estate. If there were a significant decrease in real estate values in Oregon and Washington, it may be necessary to increase the allowance for loan losses. A decline in real estate values represents one possible risk factor; other risk factors may also necessitate an increase in the allowance for loan losses.

As of March 31, 2007, our goodwill totaled $7.39 million as a result of business combinations. We follow Financial Accounting Standards Board (“FASB”) Statement of Financial Accounting Standards (“SFAS”) No. 142, which requires us to evaluate goodwill for impairment not less than annually and to write down the goodwill if the business unit associated with the goodwill cannot sustain the value attributed to it. Our evaluation of the fair value of goodwill involves a substantial amount of judgment. No impairment of goodwill has been identified during the initial and subsequent annual assessments.

Our diluted earnings per share for the first quarter of 2007 decreased 8% compared to the first quarter of 2006 primarily due to the effect of our compressing net interest margin, an increase in provision for loan losses and increases in expenses related to our ongoing expansion. Net interest margin compression appears to be a current trend for community banks as the industry adjusts to the relatively flat yield curve. The competitive pricing pressures of the current environment have generally led to lower loan yields and higher cost of funds as banks endeavor to grow loans and gather deposits.

We believe our presence in, and expansion into, high growth markets throughout the Northwest will contribute to continued loan and deposit growth. In order to minimize decreases in our loan yields, we will focus on our business model of competing primarily on the basis of service, rather than price. We are also addressing the challenge of gathering low cost deposits by hiring dedicated deposit-gathering personnel, improving operational systems and expanding our marketing efforts. We plan to carefully manage overhead expenses as we pursue our branch and administrative expansion efforts. We believe our expansion will contribute to the long-term value of our organization.

Significant items for the three months ended March 31, 2007 were as follows:

• Due to higher cost of funds associated with additional brokered deposits and promotional certificate of deposit offerings, our net interest margin decreased to 5.82% for the three months ended March 31, 2007 compared to 6.37% for the same period in 2006.

• Strong loan growth from our Columbia Basin and Willamette Valley regions contributed $33.66 million of gross loan growth since December 31, 2006. Compared to March 31, 2006, loans increased $162.98 million due to loan growth from new branches added during 2006 and strong demand for construction and commercial real estate loans throughout our market areas.

• Deposits increased $35.30 million since December 31, 2006 primarily due to promotional certificate of deposit offerings and brokered certificates of deposit. Compared to March 31, 2006, deposits increased $171.77 million due to new branches and an increase in wholesale liability deposits.

• Provision for loan losses increased $475,000 compared to the three months ended March 31, 2006 due to stronger than expected loan growth and additional charge-offs of an agricultural loan.

• Compared to the three months ended March 31, 2006, salary, benefit and occupancy expenses increased due to new branches added throughout 2006.

RESULTS OF OPERATIONS

Net Interest Income

Net interest income, our primary source of operating income, is the difference between interest income and interest expense. Interest income is earned primarily from our loan and investment security portfolios. Interest expense results primarily from customer deposits and borrowings from other sources, including Federal Home Loan Bank advances and trust preferred securities. Like most financial institutions, our net interest income increases as we are able to charge higher interest rates on loans while paying relatively lower interest rates on deposits and other borrowings.

The following table presents a comparison of average balances and interest rates:

Net interest income before provision for loan losses increased $954,955, or 8%, for the three months ended March 31, 2007 compared to the three months ended March 31, 2006. Increases in net interest income were primarily due to loan growth throughout our market areas and new branches in our Columbia Basin region. Net interest income increases were offset by increases in our cost of funds due to higher wholesale liability balances and promotional certificate of deposit pricing.

The following table presents increases in net interest income attributable to volume changes versus rate changes:

Net increase in net interest income	$	1,853		$	(898	)	$	955

During the last several years, our balance sheet has been asset sensitive, meaning that the assets re-price, or adjust to market interest rates, more frequently than the liabilities. As a result, the re-pricing of our loan portfolio was closely aligned with the series of increases in the Fed Funds rate from June 2004 to June 2006. Conversely, the re-pricing of our interest bearing liabilities has lagged behind the Fed Funds rate increases. Since June 2006, our earning asset yields have stabilized, but our cost of funds continues to rise due to the re-pricing of maturing certificates of deposit and competitive pressures to attract and retain deposit customers.

14

Net interest margin (net interest income as a percentage of average earning assets) measures how well a bank manages its asset and liability pricing and duration. Compared to the three months ended March 31, 2006, our tax equivalent net interest margin decreased from 6.37% to 5.82% for the three months ended March 31, 2007 primarily due to an increase in our cost of funds. The increase in our cost of funds resulted from customer deposit balances that shifted towards higher rate deposit accounts, promotional certificate of deposit offerings and an increase in wholesale liability borrowings to support loan growth.

Based on the current competitive environment, we expect our net interest margin will trend downward for the remainder of 2007 as competition puts pressure on pricing for new loans and our cost of funds continues to rise. Because our balance sheet is asset sensitive, a decrease in the Fed Funds rate would negatively impact interest income as our variable rate loans tied to the Prime Rate will immediately re-price (the Prime Rate has historically followed changes in the Fed Funds rate). In order to mitigate the negative effect of falling interest rates, we have been able to incorporate interest rate floors into approximately 52% of our loans. If the Fed Funds rate decreases, our net interest margin will likely decrease further.

Non-Interest Income

Non-interest income is comprised of service charges and fees, credit card discounts, financial services revenues, mortgage banking revenues and gains from the sale of loans, securities and other assets. Mortgage banking revenues include service release premiums and revenues from the origination and sale of mortgage loans. Financial services income is derived from the sale of investments and financial planning services to our customers.

The following table presents the balances and percentage changes in non-interest income:

Non-Interest Income:

	Three Months Ended March 31,
	2007		2006			% change
Service charges and fees	$	1,002	$	1,130			-11	%

Other non-interest income		294		285			3	%
Total non-interest income	$	2,646	$	2,319			14	%

Compared to the first quarter of 2006, mortgage banking revenues increased due to an increase in loan production volume from the efforts of our seasoned mortgage loan officer team.

15

Provision for Loan Losses

Our provision for loan losses represents an expense against current period income that allows us to establish an adequate allowance for loan and deposit account overdraft losses. Charges to the provision for loan losses result from our ongoing analysis of possible losses in our loan portfolio and possible losses from deposit account overdrafts (see “Allowance for Loan Losses” section of this report).

For the three months ended March 31, 2007 compared to the three months ended March 31, 2006, the provision for loan loss was higher due to relatively higher loan portfolio growth and an additional charge-off of the single agricultural loan.

Non-Interest Expense

Non-interest expense consists of salaries and benefits, occupancy costs and various other non-interest expenses.

The following table presents the components of and changes in non-interest expense:

Non-Interest Expense:
(dollars in thousands)

	Three Months Ended
	March 31,
	2007		2006		% change
Salaries and employee benefits	$	5,042	$	4,577		10	%
Occupancy expense		1,123		866		30	%
Advertising expense		122		152		-20	%
Electronic connection fees		142		106		34	%
Consulting fees		46		57		-19	%
Software licensing		85		81		5	%
Other non-interest expense		2,453		1,937		27	%
Total non-interest expense	$	9,013	$	7,776		16	%

Salaries and employee benefits increased due to employees hired to staff new branches and administrative support positions. As of March 31, 2007, full-time equivalent employees (“FTE”) totaled 369 compared to 331 as of March 31, 2006. The increase in FTE is attributable to the hiring of employees to staff new branches and administrative positions added throughout 2006. Occupancy expense and other non-interest expense increased primarily due to the incremental expenses of new branches and office space opened after March 31, 2006.

The efficiency ratio, which measures overhead costs as a percentage of total revenues, is an important measure of productivity in the banking industry. Because non-interest expense growth outpaced income growth, our efficiency ratio increased from 54.47% to 57.93% for the three months ended March 31, 2007 compared to the three months ended March 31, 2006. Increases in our efficiency ratio are primarily attributable to our branch expansion and related administrative overhead expenses.

16

Provision for Income Taxes

The following table presents the provision for income taxes and effective tax rates:

	Three Months ended
	March 31,
(dollars in thousands)	2007			2006
Provision for income taxes	$	2,067		$	2,229
Income before provision for income taxes		5,520			5,951
Effective tax rate		37.45	%		37.46	%

We expect our 2007 annual effective tax rate will range between 37.00% and 38.00% and may vary depending on our level of participation in state income tax credits.

MATERIAL CHANGES IN FINANCIAL CONDITION

ASSETS

Our assets are comprised primarily of loans for which we receive interest and principal repayments from our customers, as well as cash and investment securities.

Investment Securities

Our investment securities portfolio consists of bank-qualified municipal debt securities, debt securities issued by government agencies, mortgage-backed securities, equity securities and restricted equity securities. Investment securities totaled $39.79 million as of March 31, 2007, an increase of $2.09 million compared to December 31, 2006. During the first quarter of 2007, we purchased $2.00 million of government agency bonds to replace bonds maturing during the second quarter of 2007. We also invested $500,000 in a mutual fund that purchases Community Reinvestment Act eligible securities.

Qualifying securities may be pledged as collateral for public agency deposits or other borrowings. As of March 31, 2007, securities with an amortized cost of $23.23 million were pledged, compared to $23.30 million as of December 31, 2006.

Net unrealized losses on available-for-sale debt and equity securities totaled $99,066, or $60,530 net of tax, as of March 31, 2007, compared to net unrealized losses of $154,422, or $94,815 net of tax, as of December 31, 2006. Net unrealized losses decreased primarily due to changes in the bond market as investors measure the effects of interest rates on the discounted interest payments of bond investments. We currently have no plans to liquidate our available-for-sale securities; we expect to recover the losses over time because we have the ability to hold the securities until a market price recovery or until maturity.

17

Loans

Our loan portfolio reflects our efforts to diversify risk across a range of loan types and industries, and thereby complement the markets in which we do business. Loan products include construction, land development, real estate, commercial, consumer, agriculture and credit cards.

The following table presents our loan portfolio by loan type:

Gross loans increased $32.88 million, or 4%, since December 31, 2006. Loan growth is typically slow during the first quarter. During the first quarter of 2007, however, we experienced strong demand for real estate loans in our Willamette Valley and Columbia Basin regions.

We present loan totals as of March 31, 2006 for comparative purposes because of the seasonal nature of our business. Compared to March 31, 2006, gross loans increased $158.74 million, or 23%, due to strong demand for construction and commercial real estate loans throughout our market areas and loan growth from new branches in our Columbia Basin Region.

In the second and third quarters this year, we expect loan growth will continue, and then moderate during the fourth quarter due to the seasonal activity of agricultural and real estate construction borrowers. During 2007, we will also consider selling or participating loans as part of our strategy to diversify our loan portfolio and manage liquidity.

As of March 31, 2007, construction, land development and commercial real estate loans comprised 75% of our loan portfolio, compared to 71% as of December 31, 2006 and 69% as of March 31, 2006. Although this concentration is consistent with our Pacific Northwest community bank peers, we could become subject to future losses resulting from declines in real estate development markets and the negative economic effects of fluctuating interest rates. Some borrowers use proceeds from real estate loans for purposes other than real estate development, such as inventory and equipment purchases. In these cases, real estate market declines would represent a more indirect risk of loss because the primary source of repayment is not from real estate, but from other activities.

18

We participate in non-real estate agricultural lending, which comprises approximately 8% of our total loan portfolio. Agricultural lending has unique challenges that require special expertise. We employ experienced agriculture consultants and loan officers with experience in underwriting and monitoring agricultural loans. In addition, we diversify our agricultural loan portfolio across numerous commodity types and maintain Preferred Lender Status with the Farm Service Agency. This status allows us to participate in Farm Loan Government Guarantee Programs, which provide guarantees of up to 90% on qualified loans. Approximately 8% of our agricultural loans are guaranteed through this program; however, these guarantees are limited and loans under this program are not without credit risk.

We originate and fund single-family mortgage loans that are usually committed for sale to mortgage investors and held for less than 30 days. Mortgage loans held for sale are reported as “Loans held-for-sale” on our balance sheet. As of March 31, 2007, mortgage loans held for sale totaled $8.32 million compared to $7.54 million as of December 31, 2006.

Allowance for Loan Losses

Our allowance for loan losses represents an estimate of possible losses associated with our loan portfolio and deposit account overdrafts as of the reporting date. The adequacy of the allowance is evaluated each quarter in a manner consistent with the Interagency Policy Statement issued by the Federal Financial Institutions Examination Council (FFIEC) and with FASB SFAS Nos. 5 and 114. In determining the level of the allowance, we estimate losses inherent in all loans, and evaluate non-performing loans to determine the amount, if any, necessary for a specific reserve. Loans that do not require a specific allocation are subject to a general allocation based on historical loss rates and other subjective factors. An important element in determining the adequacy of the allowance is an analysis of loans by loan risk rating categories. We regularly review our loan portfolio to evaluate the accuracy of risk ratings throughout the life of loans.

Our methodology for estimating inherent losses in the portfolio takes into consideration all loans in our portfolio, segmented by industry type and risk rating, and utilizes a number of subjective factors in addition to historical loss rates. Subjective factors include: the economic outlook on both a national and regional level; the volume and severity of non-performing loans; the nature and value of collateral securing the loans; trends in loan growth; concentrations in borrowers, industries and geographic regions; and competitive issues that impact loan underwriting.

When a loan, or a portion of a loan, is determined to be uncollectible, it is “charged-off,” which means it is removed from the balance sheet and the reduction is charged against the allowance for loan losses. Charge-offs resulting from uncollectible deposit account overdrafts are accounted for in the same manner.

Increases to the allowance occur when we expense amounts to the loan loss provision or when we recover previously charged-off loans or overdrafts. Decreases occur when we charge-off loans or overdrafts that are deemed uncollectible. We determine the appropriateness and amount of these charges by assessing the risk potential in our portfolio on an ongoing basis.

In 2006, we reclassified our exposure for credit losses related to off-balance-sheet financial instruments to a liability account. The liability represents our estimate of possible losses associated with off-balance-sheet financial instruments, which consist of commitments to extend credit, commitments under credit card arrangements, and commercial and standby letters of credit. We had previously included the liability as a component of the allowance for loan losses. Following the reclassification, the liability is included as a component of “Accrued interest payable and other liabilities” on our balance sheet.

We evaluate the adequacy of the liability for credit losses from off-balance-sheet financial instruments based upon reviews of individual credit facilities, current economic conditions, the risk characteristics of the various categories of commitments and other relevant factors. The liability is based on estimates, which are evaluated on a regular basis, and, as adjustments become necessary, they are reported in earnings in the periods in which they become known.

⁽¹⁾ Allowance for loan losses and liability for off-balance-sheet financial instruments

20

During the three months ended March 31, 2007, we charged-off $1.00 million of an agricultural loan to a potato grower. We previously charged-off $878,574 of this loan relationship in 2006. The remaining balance of the loan was $2.38 million as of March 31, 2007. At the close of the first quarter of 2007, estimates of collateral value indicated that the stored potato crop and equipment would be sufficient to cover the $2.38 million loan balance. Inspections of the potatoes stored for processing indicated they were suitable for sale and delivery to market. Subsequent to the first quarter of 2007, we assumed contracts to sell the potatoes to processing facilities. Recent deliveries under one of these contracts were rejected due to deterioration in the quality of the collateral. As a result, during the second quarter of 2007, we charged-off $2.10 million, which represents the entire balance of the loan except that portion covered by equipment values. During the second quarter of 2007, we will also recognize a loan loss provision of $1.70 million in order to cover the write-down in excess of the specific reserve. This loan loss provision will be in addition to any other provision that we determine is necessary.

Net charge-offs as a percentage of average gross loans was 0.54% and 0.30% on an annualized basis for the three months ended March 31, 2007 and 2006, respectively. Although our net charge-offs are higher than expected for the first quarter of 2007, due to the agricultural loan charge-off, our internal loan quality indicators continue to improve.

As a percentage of gross loans at year-end, our allowance for credit losses has ranged between 1.34% and 1.46% over the 5-year period from 2002 to 2006, averaging 1.40% on an annual basis.

Non-Performing Assets

Non-performing assets consist of loans on non-accrual status, delinquent loans past due greater than 90 days, troubled debt restructured loans and other real estate owned (“OREO”). We do not accrue interest on loans for which full payment of principal and interest is not expected, or for which payment of principal or interest has been in default 90 days or more, unless the loan is well-secured and in the process of collection. Troubled debt restructured loans are those for which the interest rate, principal balance, collateral support or payment schedules were modified from original terms, beyond what is ordinarily available in the marketplace, to accommodate a borrower’s weakened financial condition. OREO represents real estate assets held through loan foreclosure or recovery activities.

The following table presents information about our non-performing assets:

Non-performing Assets:

Ratio of allowance for loan losses to total non-performing assets		289.86	%		195.28	%		311.71	%

As of March 31, 2007, an agricultural loan to a potato grower comprised $2.38 million, or 69%, of non-performing assets. This loan comprised $3.38 million, or 65%, of non-performing assets as of December 31, 2006. As previously noted, subsequent to the first quarter of 2007, we charged-off $2.10 million of this loan.

Last year, as of March 31, 2006, commercial and agricultural loans to three different agricultural borrowers, totaling $2.22 million, comprised 78% of non-performing assets. One of the agricultural loans was repaid during 2006. The other agriculture loan remained on non-accrual as of March 31, 2007, but was repaid subsequent to the end of the first quarter of 2007. The commercial loan is currently in the foreclosure process and remains on non-accrual status with a balance of approximately $615,000. Non-performing asset balances can vary significantly from period to period because they do not follow any particular pattern.

22

LIABILITIES

Our liabilities consist primarily of retail and wholesale deposits, interest accrued on deposits, notes payable and obligations to pay interest and principal on junior subordinated debentures. Retail deposits include all deposits obtained within our branch network and represent our primary source for funding loans. Wholesale liabilities include wholesale deposits obtained outside of our branch network, correspondent bank borrowings and borrowings from Federal Home Loan Bank (“FHLB”). We utilize wholesale liabilities to manage interest rate and liquidity risk. These funding sources support loan growth at times when loan growth outpaces retail deposit growth.

Deposits

We offer various deposit accounts, including non-interest bearing checking and interest bearing checking, savings, money market and certificates of deposit. The accounts vary as to terms, with principal differences being minimum balances required, length of time the funds must remain on deposit, interest rate and deposit or withdrawal options. In order to minimize our interest expense, our goal is to maximize our non-interest bearing demand deposits relative to other deposits and borrowings.

The following table presents the composition of our deposits:

Deposits:
(dollars in thousands)

	March 31, 2007					December 31, 2006					March 31, 2006
			Percent of										Percent of
	Dollar Amount		Total			Dollar Amount		Percent of Total			Dollar Amount		Total
Non-interest bearing deposits	$	217,299		24	%	$	235,037		27	%	$	214,561		30	%
Interest bearing deposits		289,716		32	%		313,433		37	%		293,187		41	%
Savings deposits		35,356		4	%		35,456		4	%		42,666		6	%
Time certificates		351,994		40	%		275,139		32	%		172,183		23	%
Total deposits	$	894,365		100	%	$	859,065		100	%	$	722,597		100	%

Total deposits increased $35.30 million, or 4%, since December 31, 2006 primarily due to promotional certificate of deposit offerings and the addition of $35.70 million of brokered certificates of deposits, net of maturities. As of December 31, 2006, interest bearing deposits included a $37.00 million temporary overnight deposit, which was subsequently withdrawn at the beginning of 2007.

Deposit totals are presented as of March 31, 2006 for comparative purposes because of the seasonal nature of our business. Compared to March 31, 2006, total deposits increased $171.77 million, or 24%, primarily due to deposit growth from our new Columbia Basin region branches and an increase in wholesale deposit balances.

We believe that increasing our retail deposits will be an ongoing challenge. Deposit customers expect innovative banking products tailored to their needs and expect interest rates that are competitive in the market place. In addition, we compete for deposits with brokerage firm money market funds that offer pricing indexed to market interest rates. We will continue to address these challenges by further developing our infrastructure and technologies to focus on customer convenience and efficiency. We have two employees who focus exclusively on deposit gathering activities for existing and potential customers. Within our company, we continue to reinforce the importance of providing superior customer service. This allows us to expand and enhance our banking relationships with our customers. These efforts begin during the initial stages of the hiring process and continue with ongoing training and regular staff meetings focused on providing superior customer service to our customers.

The following table presents a comparison of wholesale deposit balances, which are included in total deposits shown above:

Wholesale Deposits:
(dollars in thousands)

	March 31,		December 31,		March 31,
	2007		2006		2006
Brokered certificates of deposit	$	125,023	$	89,325	$	35,870
Direct certificates of deposit		9,040		5,508		4,030
Mutual fund money market deposits		18,620		18,423		—
Out-of-market public funds		5,030		3,191		4,195
	$	157,713	$	116,447	$	44,095

Brokered certificates of deposit are obtained through intermediary brokers that sell the certificates on the open market. Direct certificates of deposit are obtained through a proprietary network that solicits deposits from other financial institutions or from public entities. Mutual fund money market deposits are obtained from an intermediary that provides cash sweep services to broker-dealers and clearing firms. Out-of-market public fund depositors typically expect higher interest rates consistent with other wholesale borrowings.

Brokered and direct certificates of deposit are classified as “Time certificates” on our balance sheet. Mutual fund money market deposits and out-of-market public funds are classified as “Interest bearing demand deposits” on our balance sheet.

As of March 31, 2007, maturities of brokered certificates of deposit ranged between one month and three years. Direct certificate of deposit maturities ranged from two months to fifteen months. Mutual fund money market deposits and out-of-market public funds are payable on demand, but the balances remained stable during the first quarter of 2007.

Notes Payable

Borrowings from Federal Home Loan Bank (“FHLB”) comprise the majority of our notes payable. As of March 31, 2007, FHLB borrowings totaled $16.27 million, a decrease of $53.12 million from the December 31, 2006 balance of $69.39 million, and a decrease of $26.96 million compared to $43.23 million as of March 31, 2006. Since December 31, 2006, FHLB borrowings decreased primarily due to the repayment of a $50.00 million short-term borrowing added late in December 2006 to support liquidity requirements.

The following table presents FHLB balances and interest rates:

FHLB Borrowings:
(dollars in thousands)

	March 31,			December 31,			March 31,
	2007			2006			2006
Amount outstanding at end of period	$	16,273		$	69,387		$	43,228
Weighted average interest rate at end of period		4.05	%		5.21	%		4.11	%
Maximum amount outstanding at any month-end and during the period	$	44,182		$	70,001		$	43,228
Average amount outstanding during the period	$	32,973		$	27,603		$	23,888
Average weighted interest rate during the period		4.83	%		4.33	%		3.93	%

24

We also use lines of credit at correspondent banks to purchase federal funds for short-term funding. Available borrowings under these lines of credit totaled $66.40 million as of March 31, 2007 and December 31, 2006. No line of credit borrowings were outstanding as of March 31, 2007 and December 31, 2006. Notes payable includes a Treasury Tax and Loan note payable for $26,596 and $627,093 as of March 31, 2007 and December 31, 2006, respectively.

Trust Preferred Securities

In December 2002, Columbia formed Columbia Bancorp Trust I (“Trust”), a Delaware statutory business trust, for the purpose of issuing guaranteed undivided beneficial interests in junior subordinated debentures (“trust preferred securities”). In 2002, the Trust issued $4.00 million in trust preferred securities. The $4.12 million in debentures issued by Columbia as collateral for the trust preferred securities continue to qualify as Tier 1 capital under guidance issued by the Board of Governors of the Federal Reserve System.

Off-Balance Sheet Items — Commitments/Letters of Credit

In the normal course of business to meet the financing needs of our customers, we are party to financial instruments with off-balance-sheet risk. These financial instruments include commitments to extend credit, the issuance of letters of credit and interest rate swaps. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized on our balance sheet.

Our potential exposure to credit loss for commitments to extend credit and for letters of credit is limited to the contractual amount of those instruments. A credit loss would be triggered in the event of nonperformance by the other party. When extending off-balance sheet commitments and conditional obligations, we follow the same credit policies established for our on-balance-sheet instruments.

We may or may not require collateral or other security to support financial instruments with credit risk, depending on our loan underwriting guidelines.

The following table presents a comparison of contract commitment amounts:

Commitments:
(dollars in thousands)

	March 31,		December 31,		March 31,
	2007		2006		2006
Financial instruments whose contract amounts contain credit risk:
Commitments to extend credit	$	246,704	$	245,305	$	214,736
Undisbursed credit card lines of credit		22,519		21,265		20,587
Commercial and standby letters of credit		3,322		3,504		2,374
	$	272,545	$	270,074	$	237,697

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn, total commitment amounts do not necessarily represent future cash requirements.

The amount of collateral obtained to secure a loan or commitment, if deemed necessary, is based on our credit evaluation of the borrower. The majority of commitments are secured by real estate or other types of qualifying collateral. Types of collateral vary, but may include accounts receivable, inventory, property and equipment, and income-producing properties. Less than 10% of our commitments are unsecured. Lending commitments are distributed across all loan categories at levels roughly proportionate to concentrations in the loan portfolio.

25

Letters of credit are conditional commitments that we issue to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. The credit risk involved in issuing letters of credit parallels the risk involved in extending loans to customers. When considered necessary, we hold deposits, marketable securities, real estate or other assets as collateral for letters of credit.

Although not a contractual commitment, we offer an overdraft protection product that allows certain deposit accounts to be overdrawn up to a set dollar limit before checks will be returned. As of March 31, 2007, commitments to extend credit for overdrafts totaled $11.22 million, which represents our estimated total exposure if every customer utilized the full amount of this protection at the same time. Year-to-date average usage outstanding is much lower than this commitment, totaling approximately $206,000, or 2% of the total exposure as of March 31, 2007; approximately $233,000, or 2% of the total exposure as of December 31, 2006; and approximately $215,000, or 2% of the total exposure as of March 31, 2006.

Derivative Instruments-Interest Rate Swap

In January 2003, in connection with the issuance of $4.00 million of floating-rate trust preferred securities by Columbia Bancorp Trust I, we entered into an interest rate swap agreement (“swap”) with an unrelated third party. The swap expires in January 2008. Under the terms of the swap, we pay interest at a rate of 3.27% on a notional amount of $4.00 million and we then receive interest at the 90-day London Inter-Bank Offered Rate (“LIBOR”) on the same amount. The swap effectively converts interest payments on the $4.00 million trust preferred securities from a variable interest rate of 90-day LIBOR plus 3.30% to a fixed interest rate of 6.57% until January 2008. In January 2008, we have the option to prepay the trust preferred securities. We have classified the swap agreement as a cash flow hedge in accordance with Financial Accounting Standards Board (FASB) Statement of Financial Accounting Standards (SFAS) No. 133, “Accounting for Derivative Instruments and Hedging Activities.” The purpose of the swap is to mitigate variability in our cash flows by establishing a fixed interest payment during the initial five years of the trust preferred securities.

Commitments and Contingencies

We may become party to various legal proceedings. These matters have a high degree of uncertainty associated with them. There can be no assurance that the ultimate outcome will not differ materially from the assessment of them. There can also be no assurance that all matters that may be brought against us are known to us at any point in time.

26

LIQUIDITY AND CAPITAL RESOURCES

Liquidity

We have adopted policies to address our liquidity requirements, particularly with respect to customer needs for borrowing and deposit withdrawals. Our main sources of liquidity are customer deposits; sales and maturities of investment securities; the use of federal funds; brokered certificates of deposit; and net cash provided by operating activities. Scheduled loan repayments are a relatively stable source of funds, whereas deposit inflows and unscheduled loan prepayments are variable and are often influenced by general interest rate levels, competing interest rates available on alternative investments, market competition, economic conditions and other factors.

Measurable liquid assets include the following: cash and due from banks, excluding vault cash; interest bearing deposits with other banks; federal funds sold; held-to-maturity securities maturing within three months that are not pledged; and available-for-sale securities not pledged. Measurable liquid assets totaled $90.65 million, or 9% of total assets, as of March 31, 2007, compared to $146.34 million, or 14% of total assets, as of December 31, 2006.

During the three months ended March 31, 2007, we added, net of maturities, $35.70 million of brokered certificates of deposit in anticipation of loan growth during the second and third quarters of 2007. We also repaid $50.00 million of short-term FHLB borrowings.

Based on historical patterns, we expect liquidity will decrease during the second and third quarters of 2007 due to seasonal loan growth. In anticipation of our seasonal loan growth, we added $35 million of mutual fund money market wholesale deposits shortly after the close of the first quarter of 2007. During the fourth quarter of 2007, we expect liquidity will stabilize as loan growth subsides. We will continue to rely on retail branch deposit growth and, when necessary, we will utilize wholesale liabilities and other borrowings to meet our liquidity needs.

Our statement of cash flows reports the net changes in our cash and cash equivalents by operating, investing and financing activities. Net cash from operating activities decreased $4.00 million, or 61%, for the three months ended March 31, 2007 compared to the same period in 2006. This was the result of the decrease in net income and timing differences in the receipt and payment of accrued income and accrued expenses.

Net cash from investing activities decreased $39.97 million, or 2,470%, for the three months ended March 31, 2007 compared to same period in 2006. The decrease was primarily the result of an increase in loan growth for the three months ended March 31, 2007, compared to the three months ended March 31, 2006. To a lesser extent, the decrease was also due to a decrease in total investment maturities, an increase in securities purchases for collateralization of public deposits and an increase in property and equipment purchases related to land purchased during the three months ended March 31, 2007.

Net cash from financing activities decreased $30.93 million, or 265%, for the three months ended March 31, 2007 compared to the same period in 2006. The decrease was the result of a decrease in the growth of demand and savings deposits and repayments of short-term borrowings. The decrease was offset by an increase in time deposits from additional brokered deposits and promotional certificate of deposit products.

27

Shareholders’ Equity

As of March 31, 2007, shareholders’ equity totaled $93.71 million, compared to $91.02 million as of December 31, 2006, an increase of 3%. The 2007 year-to-date change is primarily attributable to year-to-date net income totaling $3.45 million, which was partially offset by cash dividends totaling $997,611.

During the first quarter of 2007, the Board of Directors declared a dividend of $0.10 per share, payable April 30, 2007 to shareholders of record as of April 16, 2007. Based on cash dividends paid and declared in 2007, approximately 29% of our year-to-date earnings will have been returned to shareholders, with the remainder being retained to leverage future balance sheet growth.

Capital Requirements and Ratios

The Federal Reserve Board (“FRB”) and the Federal Deposit Insurance Corporation (“FDIC”) have established minimum requirements for capital adequacy for bank holding companies and member banks. The requirements address both risk-based capital and leveraged capital. The regulatory agencies may establish higher minimum requirements if, for example, a corporation has previously received special attention or has a high susceptibility to interest rate risk.

The following table presents Columbia’s capital ratios as compared to regulatory minimums:

Capital Ratios:

							March 31, 2007			December 31, 2006
	Minimum			Well- Capitalized			Actual Ratio			Actual Ratio
Tier 1 risk-based capital		4.00	%		6.00	%		9.97	%		10.11	%
Total risk-based capital		8.00	%		10.00	%		11.17	%		11.36	%
Leverage ratio		4.00	%		5.00	%		9.42	%		8.54	%

We intend to remain “well-capitalized” by regulatory definition. Regulatory capital levels historically decrease during the second and third quarters as capital is leveraged primarily due to the increased demand for loans.

We plan to use our excess capital for continued cash dividends, stock repurchases and new branch expansion. We will also consider retiring a portion of, or all of, the trust preferred securities at the first available prepayment date in January 2008.

We expect to open two to three new branches during the time period between 2007 and 2008. We also plan to construct new branch facilities in Yakima and Sunnyside, Washington in order to replace our temporary branch locations. New branch openings will require capital resources for the following: construction of branch buildings and/or commitments on leased property, hiring new branch personnel, hiring administrative personnel to support branch operations and costs related to general overhead. We plan to further leverage our capital for continuing improvement of our core operations and technology departments and for future branch expansion.

Stock Repurchase Plan

In June 2006, the Board of Directors renewed a plan to repurchase shares of Columbia’s common stock. The Board believes the repurchases constitute a sound investment and use of our shareholders’ equity to reduce excess capital. Any stock repurchases would be made on the open market pursuant to Securities Exchange Act Rule 10b-18 at the sole discretion of Management. The repurchase plan authorizes us to repurchase common stock in an amount up to $1.50 million until the expiration date, June 30, 2007, or sooner if the maximum authorized amount of shares is repurchased prior to that date. Management determines the timing, price and number of the shares of common stock repurchased. During the three months ended March 31, 2007, we did not repurchase any stock under the stock repurchase plan.

PART II. — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

During the normal course of its business, Columbia is a party to various debtor-creditor legal actions, which individually or in the aggregate, could be material to Columbia's business, operations or financial condition. These include cases filed as a plaintiff in collection and foreclosure cases, and the enforcement of creditors' rights in bankruptcy proceedings. Management is presently aware of one legal proceeding, detailed below.

Columbia Bancorp and Columbia River Bank were named as defendants in the United States District Court for the District of Oregon in a case captioned Smith-Rattray Farms, et al. v. Columbia River Bank, et al. The plaintiffs sought compensatory, punitive and other damages totaling approximately $48.40 million, as well as injunctive and other relief. At a judicial settlement conference on March 28, 2007, all parties to the case agreed to a confidential settlement. The settlement does not involve a payment from either Columbia Bancorp or Columbia River Bank to the plaintiffs that would have any material effect on Columbia Bancorp’s earnings.

ITEM 1A. RISK FACTORS

There have been no material changes to Columbia’s risk factors previously disclosed in Part I — Item 1A “Risk Factors” of Columbia’s Form 10-K filed with the SEC on March 16, 2007 for the year ended December 31, 2006.
