NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Three and Six Months Ended June 30, 2007 and 2006

(Unaudited)

NOTE 1. Description of Business and Basis of Presentation

(a.) Description of Business

Heritage Financial Corporation (Company) is a bank holding company that was incorporated in the State of Washington in August 1997. We were organized for the purpose of acquiring all of the capital stock of Heritage Savings Bank upon our reorganization from a mutual holding company form of organization to a stock holding company form of organization. Effective September 1, 2004, Heritage Savings Bank switched its charter from a State Chartered Savings Bank to a State Chartered Commercial Bank and changed its legal name from Heritage Savings Bank to Heritage Bank. Effective September 1, 2005, Central Valley Bank changed its charter from a Nationally Chartered Commercial Bank to a State Chartered Commercial Bank.

We are primarily engaged in the business of planning, directing, and coordinating the business activities of our wholly owned subsidiaries: Heritage Bank and Central Valley Bank. The deposits of Heritage Bank and Central Valley Bank are insured by the Federal Deposit Insurance Corporation (FDIC) under the Deposit Insurance Fund (DIF). Heritage Bank conducts business from its main office in Olympia, Washington and its thirteen branch offices located in Thurston, Pierce, Mason and south King Counties of Washington State. Central Valley Bank conducts business from its main office in Toppenish, Washington and its five branch offices located in Yakima and Kittitas Counties of Washington State.

Our business consists primarily of lending and deposit relationships with small businesses including agribusiness and their owners in our market area, attracting deposits from the general public and originating for sale or investment purposes first mortgage loans on residential properties located in western and central Washington. We also make residential construction loans, income property loans, and consumer loans.

(b.) Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. These condensed consolidated financial statements should be read with our December 31, 2006 audited consolidated financial statements and its accompanying notes included in our Annual Report on Form 10-K. In our opinion, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three and six months ended June 30, 2007 are not necessarily indicative of the results that may be expected for the year ended December 31, 2007. In preparing the consolidated financial statements, we are required to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Actual results could differ from those estimates.

Certain amounts in the consolidated financial statements for the prior year have been reclassified to conform to the current consolidated financial statement presentation.

(c.) Recently Issued Accounting Pronouncements

Effective January 1, 2007, the Company adopted Financial Accounting Standards Board (FASB) Interpretation No. 48, Accounting for Uncertainties in Income Taxes, an Interpretation of FASB Statement No. 109 (FIN 48). FIN 48 prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. As of June 30, 2007 and January 1, 2007, we had an insignificant amount of unrecognized tax benefits. Our policy is to recognize interest and penalties on unrecognized tax benefits in “Federal income taxes” in the Condensed Consolidated Statements of Income. The amount of interest and penalties accrued for the three and six months ended June 30, 2007 was immaterial. The tax years subject to examination by the taxing authorities are the years ending December 31, 2006, 2005, 2004 and 2003.

In February 2007, FASB issued Statement of Financial Accounting Standards (SFAS) No. 159, The Fair Value Option for Financial Assets and Financial Liabilities. SFAS No. 159 permits entities to choose to measure many financial instruments and certain other items at fair value. This statement is effective as of the beginning of the first fiscal year that begins after November 15, 2007. Early adoption of this statement was permitted provided the entity also elected to apply the provisions of SFAS No. 157, Fair Value Measurements. Management did not early adopt SFAS No. 159. Management is assessing the impact of adopting SFAS No. 159, which will become effective on January 1, 2008, on the Company’s consolidated financial statements.

NOTE 2. Stockholders’ Equity

(a.) Earnings per Share

The following table illustrates the reconciliation of weighted average shares used for earnings per share for the noted periods.

	Three months ended June 30,				Six months ended June 30,
	2007		2006		2007		2006
Basic:
Weighted average shares outstanding	6,622,531		6,395,867		6,595,741		6,332,027
Less: Weighted average unvested restricted stock awards	(45,780	)	(75,981	)	(54,507	)	(70,265	)
Basic weighted average shares outstanding	6,576,751		6,319,886		6,541,234		6,261,762
Diluted:
Basic weighted average shares outstanding	6,576,751		6,319,886		6,541,234		6,261,762
Incremental shares from unexercised stock options and unvested restricted stock awards	104,943		217,348		138,550		221,845
Weighted average shares outstanding	6,681,694		6,537,234		6,679,784		6,483,607

Potential dilutive shares are excluded from the computation of earnings per share if their effect is anti-dilutive. For the six months ended June 30, 2007 and 2006, anti-dilutive shares outstanding related to options to acquire common stock totaled 104,122 and 41,408, respectively, as the exercise price was in excess of the market value.

(b.) Cash Dividend Declared

On June 20, 2007, we announced a quarterly cash dividend of 21.0 cents per share payable on July 30, 2007 to stockholders of record on July 16, 2007.

NOTE 3. Share Based Payment

The Company maintains a number of stock-based incentive programs, which are discussed in more detail in Note 4. Effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123R (“SFAS No. 123R”) “Share-based Payment.” SFAS No. 123R requires that all stock-based compensation be recognized as an expense in the financial statements and that such cost be measured at the fair value of the award on the grant date. This statement was adopted using the modified prospective method of application, which requires the Company to recognize compensation expense on a prospective basis. Therefore, prior period financial statements have not been restated. Under this method, in addition to reflecting compensation expense for new share-based awards, expense is also recognized to reflect the remaining service period of awards that had been included in pro forma disclosures in prior periods.

Total stock-based compensation expense (excluding ESOP expense) for the six months ended June 30, 2007 and 2006 were as follows:

	2007		2006
	(Dollars in thousands)
Compensation expense recognized	$	196	$	299
Related tax benefit recognized		26		53

As of June 30, 2007, the total unrecognized compensation expense related to non-vested stock awards was $827,000 and the related weighted average period over which it is expected to be recognized is approximately 3.1 years.

The fair value of options granted during the six months ended June 30, 2007 and 2006 is estimated on the date of grant using the Black-Scholes option pricing model based on the assumptions noted in the following table. The expected term of share options is derived from historical data and represents the period of time that share options granted are expected to be outstanding. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on historical volatility of Company shares. Expected dividend yield is based on dividends expected to be paid during the expected term of the share options.

Page 8

Grant period ended	Weighted Average Risk Free Interest Rate		Expected Term in years	Expected Volatility		Expected Dividend Yield		Weighted Average Fair Value
June 30, 2007	5.04	%	4.50	21	%	3.59	%	$	4.04
June 30, 2006	4.94	%	4.50	20	%	3.70	%	$	4.16

NOTE 4. Stock Option and Award Plans

On September 24, 1996, Heritage Bank’s stockholders approved the adoption of the 1997 stock option plan. On October 15, 1998, the Company’s stockholders approved the adoption of the 1998 stock option plan, which is similar to the 1997 plan. The 1998 plan does not affect any options granted under the 1997 plan. On April 25, 2002, the Company’s stockholders approved the adoption of the 2002 Incentive Stock Option Plan, the 2002 Director Nonqualified Stock Option Plan and the 2002 Restricted Stock Plan, which are generally similar to the 1997 and 1998 stock plans. On April 27, 2006, the Company’s stockholders approved the adoption of the 2006 Incentive Stock Option Plan, the 2006 Director Nonqualified Stock Option Plan and the 2006 Restricted Stock Plan, which are generally similar to the 1997, 1998 and 2002 stock plans.

Under these stock option plans, on the date of grant, the exercise price of the option must at least equal the market value per share of the Company’s common stock. The 1997 plan provides for the granting of options and stock awards up to 270,333 common shares. The 1998 plan provides for the grant of stock options for up to 414,750 shares and stock awards for up to 69,431 shares. The 2002 and 2006 Incentive Stock Option plans provide for the grant of stock options for up to 451,500 and 400,000 shares, respectively. The 2002 and 2006 Director Nonqualified Stock Option Plans provide for the grant of stock options for up to 73,500 and 75,000 shares, respectively. The 2002 and 2006 Restricted Stock Plans provide for the grant of stock awards for up to 52,500 and 25,000 shares, respectively.

Stock options generally vest ratably over three years and expire five years after they become exercisable which amounts to an average term of seven years. Restricted Stock awards issued have a five-year cliff vesting. The Company issues new shares to satisfy share option exercises and restricted stock awards.

The following table summarizes stock option activity for the six months ended June 30, 2007.

	Shares		Weighted Average Exercise Price		Weighted Average Remaining Contractual Term	Aggregate Intrinsic Value (in thousands)
Outstanding at December 31, 2006	638,461		$	18.79
Granted	17,550			23.40

Exercisable at June 30, 2007	406,351		$	18.87	3.18	$	2,089

The total intrinsic value of options exercised during the six months ended June 30, 2007 and 2006, was $1,204,000 and $769,000, respectively. The total fair value of shares vested during the six months ended June 30, 2007 and 2006 was $1,126,000 and $396,000, respectively.

The following table summarizes restricted stock award activity for the six months ended June 30, 2007.

Overview

Heritage Financial Corporation is a bank holding company, which primarily engages in the business activities of our wholly owned subsidiaries: Heritage Bank and Central Valley Bank. We provide financial services to our local communities with an ongoing strategic focus in expanding our commercial lending relationships, market expansion and a continual focus on asset quality. Effective January 8, 1998, our common stock began to trade on the NASDAQ National Market under the symbol “HFWA”.

The following table provides relevant net interest income information for selected time periods. The average loan balances presented in the table are net of allowances for loan losses. Nonaccrual loans have been included in the tables as loans carrying a zero yield.

Earnings Summary

Net income was $0.39 per diluted share for the three months ended June 30, 2007 and June 30, 2006. Actual earnings for the three months ended June 30, 2007 were $2,627,000 compared to $2,535,000 for the same period in 2006, an increase of 3.6%. Net income for the six months ended June 30, 2007 was $0.75 per diluted share compared to $0.79 per diluted share for the same period last year, a decrease of 4.8%. Actual earnings for the six months ended June 30, 2007 were $5,000,000 compared to $5,100,000 for the same period in 2006, a decrease of 2.0%.

Return on average equity for the quarter ended June 30, 2007 was 12.76% compared to 14.13% for the same period last year. Average equity increased by $10.6 million to $82.6 million for the three months ended June 30, 2007 versus $72.0 million for the same period last year. For the six months ended June 30, 2007, the Company’s return on average equity was 12.35% compared to 14.65% for the six months ended June 30, 2006. Average equity for the six months ended June 30, 2007 increased $11.4 million to $81.6 million from $70.2 million for the six months ended June 30, 2006. The Company’s capital position remains strong at 9.01% of total assets as of June 30, 2007, down slightly from 9.09% at June 30, 2006.

Net Interest Income

Net interest income before provision for loan losses for the three months ended June 30, 2007 increased 3.6% to $9,102,000 from $8,784,000 for the same quarter in 2006. Net interest income before provision for loan losses for the six months ended June 30, 2007 increased 4.2% to $18,000,000 from $17,269,000 for the same period in 2006. The net interest margin (net interest income divided by average interest earning assets) decreased to 4.50% for the current quarter from 4.83% for the same quarter last year. The net interest margin decreased to 4.55% for the six months ended June 30, 2007 from 4.89% for the same period in 2006. The lower net interest margins are due to a continuation of a relatively “flat” yield curve and a very competitive business environment. Although management expects this trend to continue, the magnitude of the decrease in net interest margin is expected to decrease.

Interest income increased $2.2 million, or 16.5%, for the three months ended June 30, 2007 as compared to the second quarter last year and interest expense increased $1.9 million, or 41.0%, during this same period. Interest income for the six months ended June 30, 2007 increased $4.8 million, or 18.5%, as compared to the same period last year and interest expense increased $4.0 million, or 47.5%, during this same period. Loans averaged $764.8 million with an average yield of 7.94% for the three months ended June 30, 2007 compared to average loans of $680.5 million with an average yield of 7.62% for the same period in 2006. Loans averaged $751.3 million with an average yield of 7.93% for the six months ended June 30, 2007 compared to average loans

Page 12

of $662.4 million with an average yield of 7.56% for the same period in 2006. Certificates of deposit averaged $350.7 million with an average cost of 4.89% for the three months ended June 30, 2007 compared to $297.9 million with an average cost of 4.00% for the same period in 2006. Certificates of deposit averaged $344.5 million with an average cost of 4.85% for the six months ended June 30, 2007 compared to $291.7 million with an average cost of 3.83% for the same period in 2006.

Provision for Loan Losses

The provision for loan losses was $180,000 for the three months ended June 30, 2007, an increase of $80,000 over the provision for loan losses during the second quarter of 2006. The provision for loan losses was $360,000 for the six months ended June 30, 2007 up from $240,000 for the same period in 2006. The increase in the provision for loan losses was due to net recoveries recognized in the six months ended June 30, 2006 which lowered the provision required to maintain an adequate allowance for loan losses.

Noninterest Income

Noninterest income increased 16.3% to $2,229,000 for the three months ended June 30, 2007 compared with $1,917,000 for the same quarter in 2006. Noninterest income increased 15.6% to $4,262,000 for the six months ended June 30, 2007 from $3,688,000 for same period in 2006. The increases for the three and six months ended June 30, 2007 were primarily due to increases in brokered mortgage income of $120,000 and $175,000, respectively, service charges of $141,000 and $257,000, respectively, and in merchant visa income of $96,000 and $178,000, respectively. These increases are due substantially to increased volume in these activities.

Noninterest Expense

Noninterest expense increased 5.3% to $7,176,000 during the three months ended June 30, 2007 compared to $6,816,000 for the same period during 2006.

Noninterest expense increased 9.6% to $14,362,000 for the six months ended June 30, 2007 from $13,100,000 for the same period last year. This increase was due to increases in salaries and benefits expense of $390,000, occupancy and equipment expense of $126,000, data processing expense of $124,000 and merchant visa expense of $168,000.

The efficiency ratio for the quarter ended June 30, 2007 was 63.3% compared to 63.7% for the comparable quarter in 2006. The efficiency ratio for the six months ended June 30, 2007 was 64.5% compared to 62.5% for the same period last year. The efficiency ratio increases are primarily a result of increased noninterest expense due to the factors listed above. The efficiency ratio consists of noninterest expense divided by the sum of net interest income before provision for loan losses plus noninterest income.

Lending Activities

As indicated in the table below, total loans (including loans held for sale) increased to $790.2 million at June 30, 2007 from $749.7 million at December 31, 2006.

Allowance for loan losses to nonperforming loans		637.51	%		360.05	%
Nonperforming assets to total assets		0.18	%		0.36	%

Nonperforming assets decreased to $1,605,000, or 0.18% of total assets at June 30, 2007 from $3,032,000, or 0.36% of total assets at December 31, 2006 due substantially to pay-offs of nonaccrual loans. We believe that we are adequately reserved for losses in the portfolio as of June 30, 2007. Potential problem loans are those loans that are currently accruing interest, but which are considered possible credit problems because financial information of the borrowers causes us concerns as to their ability to comply with the present repayment program and could result in placing the loan on nonaccrual.

Analysis of Allowance for Loan Losses

Management maintains an allowance for loan losses to absorb estimated credit losses associated with the loan portfolio, including all binding commitments to lend. We determine an adequate allowance through our ongoing quarterly loan quality assessments.

We assess the estimated credit losses inherent in our non-classified loan portfolio by considering a number of elements including:

• Risk rating of the credit portfolio;

• Levels and trends in delinquencies and nonaccruals;

• Trends in loan demand and structure including terms and interest rates;

Page 14

• National and local economic trends;

• Specific industry conditions such as commercial and residential construction;

• Concentrations of credits in specific industries;

• Bank regulatory examination results and our own credit examinations; and

• Recent loss experience in the portfolio.

We calculate an adequate allowance for the non-classified portion of our loan portfolio based on an appropriate percentage risk factor that is calculated based on the above-noted elements and trends. For each classified loan, we may have a specific provision based on careful analysis of that loan’s credit and collateral factors. Our analysis of an adequate allowance combines the provisions made for both our non-classified loans and the specific provisions made for each classified loan.

While we believe we use the best information available to determine the allowance for loan losses, net income could be significantly affected if circumstances differ substantially from the assumptions used in determining the allowance, unforeseen market conditions arise or if we are directed to make adjustments to the allowance for loan losses by our regulators.

The following table summarizes the changes in our allowance for loan losses:

	Six Months Ended June 30,

Total loans outstanding at end of period	$	789,813		$	722,111

Allowance for loan losses to loans		1.30	%		1.35	%
Ratio of net recoveries (charge offs) during period to average loans outstanding		(0.03	)%		0.04	%

While pursuing our growth strategy, we continue to employ prudent underwriting and sound monitoring procedures to maintain asset quality. The allowance for loan losses during the six months ended June 30, 2007 increased by $127,000 to $10.2 million from $10.1 million at December 31, 2006. Based on management’s assessment of loan quality, the Company believes that its allowance for loan losses is at an appropriate level under current economic conditions.

Page 15

Liquidity and Sources of Funds

Our primary sources of funds are customer and local government deposits, loan repayments, loan sales, interest earned on and proceeds from investment securities, and advances from the Federal Home Loan Bank (FHLB) of Seattle. These funds, together with retained earnings, equity, and other borrowed funds, are used to make loans, acquire investment securities and other assets, and fund continuing operations. While maturities and scheduled amortization of loans are a predictable source of funds, deposit flows and mortgage prepayments are greatly influenced by the level of interest rates, economic conditions, and competition.

We must maintain an adequate level of liquidity to ensure the availability of sufficient funds to fund loan originations and deposit withdrawals, satisfy other financial commitments, and fund operations. We generally maintain sufficient cash and short-term investments to meet short-term liquidity needs. At June 30, 2007, cash and cash equivalents totaled $43.2 million, and investment securities classified as either available for sale or held to maturity with maturities of one year or less amounted to $17.8 million, or 2.0% of total assets. At June 30, 2007, our banks maintained a credit facility with the FHLB of Seattle for $160.7 million, with $41.8 million in FHLB borrowings as of June 30, 2007.

Capital

Stockholders’ equity at June 30, 2007 was $81.6 million compared with $78.6 million at December 31, 2006. During the six months ended June 30, 2007, we declared dividends of $2.8 million, realized income of $5.0 million, recorded $54,000 in unrealized losses on securities available for sale, net of tax, repurchased $1.0 million of common stock and realized the effects of exercising stock options, stock option compensation and earned ESOP and restricted stock shares totaling $1.8 million.

Banking regulations require bank holding companies and banks to maintain a minimum leverage ratio of core capital to adjusted quarterly average total assets of at least 3%. At June 30, 2007 and December 31, 2006, our leverage ratio was 8.0%. 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 common shareholders’ equity, while Tier II capital includes the allowance for loan losses, 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%. Our Tier I and total risk based capital ratios were 8.8% and 10.1%, respectively, at June 30, 2007 compared with 9.1% and 10.4%, respectively, at December 31, 2006.

During 1992, the FDIC published the qualifications necessary to be classified as a “well-capitalized” bank, primarily for assignment of FDIC insurance premium rates beginning in 1993. To qualify as “well-capitalized”, banks must have a Tier I risk based capital ratio of at least 6%, a total risk based capital ratio of at least 10%, and a leverage ratio of at least 5%. Heritage Bank and Central Valley Bank qualified as “well-capitalized” at June 30, 2007.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our results of operations are highly dependent upon our ability to manage interest rate risk. We consider interest rate risk to be a significant market risk that could have a material effect on our financial condition and results of operations. In our opinion, there has not been a material change in our interest rate risk exposure since our most recent year-end at December 31, 2006.

We do not maintain a trading account for any class of financial instrument nor do we engage in hedging activities or purchase high-risk derivative instruments. Moreover, we have no material risk with foreign currency exchange rate risk or commodity price risk.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of disclosure controls and procedures. We maintain controls and procedures designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934 are recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. Based upon their evaluation of those controls and procedures, the Chief Executive and Chief Financial officers of the Company concluded that the Company’s disclosure controls and procedures were adequate as of June 30, 2007.

(b) Changes in internal control over financial reporting. We made no changes in our internal controls over financial reporting that occurred during the Company’s quarter ended June 30, 2007, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
