FINANCIAL STATEMENTS The Unaudited Pro Forma Combined Condensed Consolidated Balance Sheet ("Pro Forma Balance Sheet") combines the historical Balance Sheets of American River Bankshares ("AMRBK") and Bank of Amador ("BNKA") giving effect to the consummation of the merger as of September 30, 2004. The Unaudited Pro Forma Combined Condensed Consolidated Statements of Income ("Pro Forma Income Statements") for the nine months ended September 30, 2004 and the year ended December 31, 2003 give effect to the consummation of the merger as if such transaction had become effective at the beginning of each respective period. The merger will be accounted for using the purchase method of accounting and giving effect to the related pro forma adjustments described in the accompanying notes to the Unaudited Pro Forma Combined Condensed Consolidated Financial Statements ("Pro Forma Financial Statements"). The Pro Forma Financial Statements included herein are presented for information purposes only. They include various estimates and may not necessarily be indicative of the financial position or results of operations that would have occurred if the merger had been consummated on the date or at the beginning of the periods indicated or which may be obtained in the future. These pro forma financial statements and accompanying notes should be read together with the historical financial statements, including the notes thereto, of AMRBK that have been presented in prior filings with the SEC and of BNKA, which are included and incorporated by reference herein. We anticipate that the merger will provide the combined company with financial benefits including cost savings and enhanced revenue opportunities. The pro forma information, while helpful in illustrating the financial characteristics of the combined company under one set of assumptions, does not reflect benefits of expected cost savings or revenue opportunities and, accordingly, does not attempt to predict or suggest future operating results. It also does not necessarily reflect what the historical results of the combined company would have been had the companies been combined during these periods. Note (1) - Basis of Presentation The merger with BNKA was completed on December 3, 2004 through the exchange of 850,627 shares of AMRBK's common stock valued at approximately $20,054,000 and cash of approximately $10,763,000 for all of the outstanding common shares of AMRBK. The shares and the cash exchanged assumes no BNKA shareholders exercise their dissenters' rights and assumes no holdback of cash as set forth in the merger agreement. Management of AMRBK determined the estimated fair value adjustments for assets acquired and liabilities assumed by AMRBK with the assistance of certain investment banking and consulting firms. Based upon a preliminary analysis, it is anticipated that book value will be a reasonable approximation of fair value with the exception of the valuation of BNKAs investment securities portfolio. The resulting core deposit intangible is being amortized into income over eight years. Deferred tax assets and liabilities were recorded to reflect the tax consequences associated with differences between the tax basis and book basis of the assets acquired and liabilities assumed, using a tax rate of 40%. Certain reclassifications have been made to BNKA's historical financial information in order to conform to AMRBK's financial information. Note (2) - Pro Forma Adjustments Summarized below are the pro forma adjustments necessary to reflect the merger based on the purchase method of accounting: (a) Cash consideration paid to Bank of Amador shareholders assuming no holdback of cash at the closing, in addition to cash paid for merger related costs. (b) Adjustments to reflect the fair value of the assets and liabilities are not considered material and are omitted for this presentation. Page 18 of 19 Pages (c) Goodwill of $16.0 million and core deposit intangible of $2.8 million, resulting from the application of the purchase method of accounting. Goodwill results from the calculation below and assumes no BNKA shareholders exercised their dissenters' rights: Cost to Acquire BNKA: --------------------- AMRBK Common Stock Issued $ 20,054 Cash paid to BNKA shareholders 10,763 Direct costs of merger 365 ---------- Consideration Paid for BNKA 31,182 Net Assets Acquired: BNKA Stockholders' Equity at September 30, 2004 $ 15,420 Less: Pre Merger Costs, net of tax (1,912) ---------- Subtotal $ 13,508 Core Deposit Intangible 2,784 Tax Effect of Core Deposit Intangible (1,114) Net Core Deposit Intangible 1,670 Estimated Goodwill Recognized $ 16,004 Core deposit intangible estimated value at 2.5 percent of core deposits acquired (exclusive of time deposits greater than $100,000). Tax effect estimated at 40 percent. (d) Deferred tax asset relates to merger-related costs expected to be incurred ($1,2 million), less direct costs to issue the new shares ($.4 million) (e) Deferred taxes of $1.1 million. (f) Issuance of American River Bankshares common stock, based on $23.576, to Bank of Amador shareholders, less the elimination of Bank of Amador common stock. (g) Elimination of Bank of Amador retained earnings and unrealized net gains on securities available for sale. (h) Opportunity costs on cash consideration paid to Bank of Amador shareholders (assumed interest rate of 1.00%). (i) Amortization expense related to the estimated core deposit intangible asset. The core deposit intangible will be amortized on a straight-line basis over its estimated useful life of 8 years. (j) Adjustment for merger costs paid by BNKA through September 30, 2004. (k) The provision for income taxes related to pro forma adjustments is computed using a combined federal and state tax rate of 40%. Page 19 of 19 Pages
