Parent may, at any time prior to the Effective Time (including, to the extent permitted by applicable law, after the Company’s shareholders have approved the principal terms of the Merger) change the method of effecting the acquisition of the Company and the Company Subsidiaries (including, without limitation, the provisions of this Article II and including, without limitation, by electing not to merge the Company or any Company Subsidiary with Parent or any of its existing Subsidiaries, but rather with a merger subsidiary of Parent) if and to the extent it deems such change to be necessary, appropriate or desirable; provided, however, that no such change shall (i) alter or change the amount or kind of consideration to be issued to holders of Company Common Stock as provided for in this Agreement (the “Merger Consideration”), (ii) adversely affect the tax treatment of the Company’s shareholders as a result of receiving the Merger Consideration, (iii) materially impede or delay consummation of the transactions contemplated by this Agreement or (iv) otherwise be materially prejudicial to the interests of the shareholders of the Company.

(b) Articles of Incorporation and By-Laws. The articles of incorporation and by-laws of Parent immediately after the Effective Time shall be those of Parent as in effect immediately prior to the Effective Time.

(c) Directors and Officers of Parent. Except that the Parent Board shall be increased by one, such vacancy to be filled by a director of the Company selected by the Parent Board, the directors and officers of Parent immediately after the Effective Time shall be the directors and officers of Parent immediately prior to the Effective Time, until such time as their successors shall be duly elected and qualified.

(d) Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in Section 23B.11.060 of the WBCA, including any regulations or rules promulgated thereunder. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, all the property, rights, privileges, powers and franchises of the Company shall vest in Parent, and all debts, liabilities, obligations, restrictions, disabilities and duties of the Company shall become the debts, liabilities, obligations, restrictions, disabilities and duties of Parent.

2.02. Effective Date and Effective Time. On such date as Parent selects (and promptly provides notice thereof to Company), which shall be within ten days after the last to occur of the expiration of all applicable waiting periods in connection with approvals of Governmental Authorities and the receipt of all approvals of Governmental Authorities and all conditions to the consummation of the Merger are satisfied or waived (or, at the election of Parent, on the last

Business Day of the month in which such tenth day occurs or, if such tenth day occurs on one of the last five Business Days of such month, on the last Business Day of the succeeding month or, if such tenth day occurs in March 2006, then on the first Business Day in April 2006), or on such earlier or later date as may be agreed in writing by the parties, the Agreement of Merger shall be filed with the Washington Secretary of State, in accordance with all appropriate legal requirements together with such certificates or other documents executed as may be required by law, and the Merger provided for herein shall become effective upon such filing. The date of such filing is herein called the “Effective Date.” The “Effective Time” of the Merger shall be the time of such filing.

ARTICLE III

CONSIDERATION; EXCHANGE PROCEDURES

3.01. Effect on Capital Stock. Subject to the other provisions of this Article III, at the Effective Time of the Merger, by virtue of the Merger and without any additional action on the part of the holders of shares of Parent Common Stock:

(a) Parent Common Stock. Each share of Parent Common Stock issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock of Parent, and shall not be affected by the Merger;

(b) Company Common Stock. Each share of Company Common Stock, issued and outstanding immediately prior to the Effective Time of the Merger (other than Dissenters’ Shares and Treasury Shares, as defined below) shall be converted into the right to receive either Parent Common Stock or cash as provided in Section 3.02(a);

(c) Dissenter’s Shares. All shares of Company Common Stock as to which a shareholder has taken the actions required by Section 23B.13 of the WBCA relating to dissenters’ rights (“Dissenters’ Shares”) shall not be converted into or represent a right to receive Parent Common Stock or cash hereunder unless and until such shares have lost their status as dissenting shares, at which time such shares shall either be converted into cash or Parent Common Stock pursuant to Section 3.08; and

(d) Cancellation of Certain Shares. Any shares of Company Common Stock held by Parent or any Parent Subsidiary, or Company or any Company Subsidiary, other than those held in a fiduciary capacity or as a result of debts previously contracted (“Treasury Shares”), shall be cancelled and retired at the Effective Time of the Merger and no consideration shall be issued in exchange therefor.

3.02. Conversion of Company Common Stock.

(a) Subject to the other provisions of this Article III, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time of the Merger (other than Dissenters’ Shares and Treasury Shares) shall, by virtue of the Merger, be converted

into the right to receive, at the election of the holder thereof as provided in Section 3.03, either (i) cash (the “Cash Consideration”) in an amount equal to the Company Common Stock Value (defined below) or (ii) a number of shares of Parent Common Stock (the “Stock Consideration”) equal to the Company Common Stock Value divided by the Parent Measuring Price (together, the “Merger Consideration”). “Company Common Stock Value” as calculated immediately prior to the Effective Time by Parent shall mean an amount equal to (i) the sum of (x) $37,750,000 plus (y) the aggregate exercise price of all Company Stock Options exercised by the holders after the date hereof and prior to the Effective Date, plus (z) the aggregate exercise price of all In-the-Money Company Stock Options (as defined below) outstanding immediately prior to the Effective Time, divided by (ii) the sum of (x) the total number of shares of Company Common Stock outstanding (which number includes restricted stock awards outstanding at the Effective Date) immediately prior to the Effective Time plus (y) the total number of shares of Company Common Stock subject to such In-the-Money Company Stock Options outstanding immediately prior to the Effective Time, rounded to the nearest cent. For the avoidance of doubt, the aggregate consideration for all of the Company Common Stock and Company Stock Options, in each case outstanding immediately prior to the Effective Time, shall be $37,750,000 if no Company Stock Options are exercised between the execution of this Agreement and the Effective Date, and up to a maximum of $39,858,090 if all holders of Company Stock Options exercise their options at or before the Effective Date, it being hereby agreed between Parent and Company that the difference between the final aggregate consideration paid and $37,750,000, if any, will be equal to the increase in the Company’s shareholders’ equity attributable to the exercise of Company Stock Options between the execution of this Agreement and the Effective Date. “In-the-Money Company Stock Options” shall mean those Company Stock Options having an exercise price of less than $45.70 per share. A shareholder may elect to receive a combination of cash and Parent Common Stock in exchange for his or her shares of Company Common Stock; provided, however, that with respect to each individual share of Company Common Stock held, a shareholder must elect to receive either all cash or all Parent Common Stock.

(b) At the Effective Time of the Merger, the stock transfer books of the Company shall be closed as to holders of Company Common Stock immediately prior to the Effective Time of the Merger and no transfer of Company Common Stock by any such holder shall thereafter be made or recognized. If, after the Effective Time of the Merger, certificates representing shares of Company Common Stock are properly presented in accordance with Article III of this Agreement to the Exchange Agent (as defined in Section 3.03), such certificates shall be cancelled and exchanged for certificates representing the number of whole shares of Parent Common Stock into which such shares were converted, if any, and/or a check representing the amount of cash, if any, into which the Parent Common Stock represented thereby was converted in the Merger, plus any payment for a fractional share of Parent Common Stock.

3.03. Election and Proration Procedures.

(a) Election Forms and Types of Elections. An election form and other appropriate and customary transmittal materials (which shall specify that delivery shall be effected, and risk

of loss and title to the certificates theretofore representing shares of Company Common Stock shall pass, only upon proper delivery of such certificates to the Exchange Agent selected by Parent (the “Exchange Agent”)) in such form and substance as designated by Parent (the “Election Form”) shall be mailed at Parent’s expense no less than 40 days prior to the Effective Time of the Merger or on such other date as Parent and the Company shall mutually agree (the “Mailing Date”) to each holder of record of Company Common Stock as of a date of Parent’s choice which is at least three Business Days prior to the Mailing Date (the “Election Form Record Date”). Parent shall make available one or more Election Forms as may be reasonably requested by all persons who become holders of Company Common Stock after the Election Form Record Date and prior to the Election Deadline (as defined in Section 3.03(b)), and the Company shall promptly provide or cause to be provided to the Exchange Agent all information reasonably necessary for the Exchange Agent to perform its obligations as specified herein. Each Election Form shall permit the holder (or the beneficial owner through appropriate and customary documentation and instructions) to elect (an “Election”) to receive either (i) Parent Common Stock (a “Stock Election”) with respect to all of such holder’s shares of Company Common Stock, (ii) cash (a “Cash Election”) with respect to all of such holder’s shares of Company Common Stock, or (iii) Parent Common Stock in exchange for a specified number of shares of Company Common Stock (a “Combination Stock Election”) and cash in exchange for a specified number of shares of Company Common Stock (a “Combination Cash Election”). Any shares of Company Common Stock (other than Dissenters’ Shares or Treasury Shares) with respect to which the holder (or indirectly the beneficial owner) shall not have submitted to the Exchange Agent an effective, properly completed Election Form, which was received prior to the Election Deadline, shall be deemed to be “Undesignated Shares” (each an “Undesignated Share”) hereunder.

(b) Proper and Timely Election. Any Election shall have been properly made and effective only if the Exchange Agent shall have actually received a properly completed Election Form by 5:00 P.M. Pacific Time on the 30th day following the Mailing Date (or such other time and date as the Company and Parent may mutually agree) (the “Election Deadline”). An Election Form shall be deemed properly completed only if an Election is indicated for each share of Company Common Stock covered by such Election Form and if accompanied by one or more certificates (or customary affidavits and indemnification regarding the loss or destruction of such certificates or the guaranteed delivery of such certificates) representing all shares of Company Common Stock covered by such Election Form, together with duly executed transmittal materials included in or required by the Election Form. Any Election Form may be revoked or changed by the person submitting such Election Form prior to the Election Deadline. In the event an Election Form is revoked prior to the Election Deadline, the shares of Company Common Stock represented by such Election Form shall automatically become Undesignated Shares unless and until a new Election is properly and timely made with respect to such shares on or before the Election Deadline, and Parent shall cause the certificates representing such shares of Company Common Stock to be promptly returned without charge to the person submitting the revoked Election Form upon written request to that effect from the holder who submitted such Election Form. Subject to the terms of this Agreement and of the Election Form, the Exchange Agent shall have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in the

Election Forms, and any decisions of Parent and Company required by the Exchange Agent and made in good faith in determining such matters shall be binding and conclusive. Neither Parent nor the Exchange Agent shall be under any obligation to notify any person of any defect in an Election Form.

(c) Allocation. Notwithstanding anything in this Agreement to the contrary, the number of shares of Company Common Stock to be converted into the right to receive Cash Consideration in the Merger (the “Cash Election Number”) shall be equal to 50% of the difference between (i) the total number of shares of Company Common Stock outstanding immediately prior to the Effective Time and (ii) the sum of (A) the number of Dissenters’ Shares, if any, and (B) the number of Treasury Shares. The number of shares of Company Common Stock to be converted into the right to receive Stock Consideration in the Merger (the “Stock Election Number”) shall be equal to the number of shares of Company Common Stock issued and outstanding immediately prior to the Effective Time of the Merger less the sum of (i) the Cash Election Number, (ii) the number of Dissenters’ shares, if any, and (iii) the number of Treasury Shares.

(d) Payment and Proration. As promptly as practicable but not later than five Business Days after the Effective Time of the Merger, Parent shall cause the Exchange Agent to effect the allocation among the holders of Company Common Stock of rights to receive Parent Common Stock or cash in the Merger in accordance with the Election Forms as follows:

(i) In the event that the aggregate number of shares of Company Common Stock in respect of which Cash Elections and Combination Cash Elections have been made (collectively, the “Cash Election Shares”) exceeds the Cash Election Number, all shares in respect of which Stock Elections and Combination Stock Elections have been made (the “Stock Election Shares”) and all Undesignated Shares in respect of which Stock Elections are deemed to have been made (it being understood that in such case all Undesignated Shares shall be deemed to be shares in respect of which Stock Elections have been made) shall be converted into the right to receive Stock Consideration, and all Cash Election Shares shall be converted into the right to receive Stock Consideration or Cash Consideration in the following manner:

(A) Cash Election Shares shall be deemed converted to Stock Election Shares, on a pro-rata basis for each record holder of shares of Company Common Stock with respect to those shares, if any, of such record holder that are Cash Election Shares, so that the number of Cash Election Shares so converted, when added to the existing Stock Election Shares, shall equal as closely as practicable the Stock Election Number, and all such Cash Election Shares so converted shall be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests); and

(B) any remaining Cash Election Shares shall be converted into the right to receive Cash Consideration.

(ii) In the event that the aggregate number of Stock Election Shares exceeds the Stock Election Number, all Cash Election Shares and all Undesignated Shares in respect of which Cash Elections are deemed to have been made (it being understood that in such case all Undesignated Shares shall be deemed to be shares in respect of which Cash Elections have been made) shall be converted into the right to receive Cash Consideration, and all Stock Election Shares shall be converted into the right to receive Stock Consideration or Cash Consideration in the following manner:

(A) Stock Election Shares shall be deemed converted into Cash Election Shares, on a pro-rata basis for each record holder of shares of Company Common Stock with respect to those shares, if any, of such record holder that are Stock Election Shares, so that the number of Stock Election Shares so converted, when added to the existing Cash Election Shares, shall equal as closely as practicable the Cash Election Number, and all such Stock Election Shares so converted shall be converted into the right to receive Cash Consideration; and

(B) the remaining Stock Election Shares shall be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests).

(iii) In the event that neither clause (i) nor clause (ii) of this Section 3.03(d) is applicable, on a pro-rata basis, Undesignated Shares shall be deemed Stock Election Shares such that the total number of Stock Election Shares equals the Stock Election Number and any remaining Undesignated Shares shall be deemed Cash Election Shares and (A) all Cash Election Shares and all Undesignated Shares in respect of which Cash Elections are deemed to have been made shall be converted into the right to receive Cash Consideration, and (B) all Stock Election Shares and all Undesignated Shares in respect of which Stock Elections are deemed to have been made shall be converted into the right to receive Stock Consideration (and cash in lieu of fractional interests).

(e) Calculations. Any calculation of a portion of a share of Parent Common Stock shall be rounded to the nearest ten-thousandth of a share, and any cash payment shall be rounded to the nearest cent.

3.04. Rights as Shareholders; Stock Transfers. At the Effective Time, holders of Company Common Stock shall cease to be, and shall have no rights as, shareholders of the Company other than to receive the consideration provided under this Article III. After the Effective Time, there shall be no transfers on the stock transfer books of the Company of shares of Company Common Stock.

3.05. No Fractional Shares. Notwithstanding any other provision hereof, no fractional shares of Parent Common Stock and no certificates or scrip therefor, or other evidence of ownership thereof, will be issued in the Merger; instead, Parent shall pay to each holder of Company Common Stock who would otherwise be entitled to a fractional share of Parent Common Stock (after taking into account all certificates of Company Common Stock delivered by such holder) an amount in cash (without interest) determined by multiplying such fraction by

the Parent Measuring Price. No holder will be entitled to dividends, voting rights or any other rights as a shareholder in respect of any fractional share of Parent Common Stock.

3.06. Exchange Procedures.

(a) Exchange Agent. No later than the Effective Time of the Merger, Parent shall deposit with the Exchange Agent certificates representing the number of shares of Parent Common Stock issuable in the Merger and the amount of cash payable in the Merger (the “Exchange Fund”). The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to Parent Common Stock held by it from time to time hereunder, except that it shall receive and hold all dividends or other distributions paid or distributed with respect to such shares for the account of the persons entitled thereto.

(b) Exchange of Certificates and Cash. After completion of the allocation procedure set forth in Section 3.03, each holder of a certificate formerly representing shares of Company Common Stock (other than Dissenters’ Shares or Treasury Shares) who surrenders or has surrendered such certificate (or customary affidavits and indemnification regarding the loss or destruction of such certificate), together with duly executed transmittal materials included in or required by the Election Form, to the Exchange Agent shall, upon acceptance thereof, be entitled to a certificate representing Parent Common Stock and/or cash into which the shares of Company Common Stock shall have been converted pursuant hereto, as well as cash in lieu of any fractional shares of Parent Common Stock to which such holder would otherwise be entitled. The Exchange Agent shall accept such certificate representing shares of Company Common Stock upon compliance with such reasonable and customary terms and conditions as the Exchange Agent may impose to effect an orderly exchange thereof in accordance with normal practices. Until surrendered as contemplated by this Section 3.06, each certificate representing shares of Company Common Stock shall be deemed from and after the Effective Time of the Merger to evidence only the right to receive cash and/or Parent Common Stock, as the case may be, upon such surrender. Parent shall not be obligated to deliver the consideration to which any former holder of Company Common Stock is entitled as a result of the Merger until such holder surrenders his certificate or certificates representing shares of Company Common Stock for exchange as provided in this Article III. If any certificate for shares of Company Common Stock, or any check representing cash and/or declared but unpaid dividends, is to be issued in a name other than that in which a certificate surrendered for exchange is issued, the certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer and the person requesting such exchange shall affix any requisite stock transfer tax stamps to the certificate surrendered or provide funds for their purchase or establish to the satisfaction of the Exchange Agent that such taxes are not payable.

(c) Affiliates. Certificates surrendered for exchange by any person constituting an “affiliate” of the Company for purposes of Rule 145 under the Securities Act shall not be exchanged for certificates representing whole shares of Parent Common Stock until Parent has received a written agreement from such person as provided in Section 6.06.

(d) No Liability. Notwithstanding the foregoing, neither the Exchange Agent nor any party hereto shall be liable to any former holder of Company Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(e) Voting and Dividends. Former shareholders of record of the Company shall not be entitled to vote after the Effective Time of the Merger at any meeting of Parent shareholders until such holders have exchanged their certificates representing Company Common Stock for certificates representing Parent Common Stock in accordance with the provisions of this Agreement. Until surrendered for exchange in accordance with the provisions of this Section 3.06, each certificate theretofore representing shares of Company Common Stock (other than Dissenters’ Shares and Treasury Shares) shall from and after the Effective Time of the Merger represent for all purposes only the right to receive shares of Parent Common Stock, cash in lieu of fractional shares and/or cash, as set forth in this Agreement. No dividends or other distributions declared or made after the Effective Time of the Merger with respect to Parent Common Stock with a record date after the Effective Time of the Merger shall be paid to the holder of any unsurrendered certificate of Company Common Stock with respect to the shares of Parent Common Stock represented thereby, until the holder of such certificate of Company Common Stock shall surrender such certificate. Subject to the effect of applicable laws, following surrender of any such certificates of Company Common Stock for which shares of Parent Common Stock are to be issued, there shall be paid to the holder of the certificates without interest, (i) the amount of any cash payable with respect to a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 3.05 and the amount of dividends or other distributions with a record date after the Effective Time of the Merger theretofore paid with respect to such whole shares of Parent Common Stock, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time of the Merger but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Parent Common Stock.

(f) Unclaimed Portion of Exchange Fund. Any portion of the Exchange Fund that remains unclaimed by the shareholders of the Company for six months after the Effective Time shall be paid to Parent. Any shareholders of the Company who have not theretofore complied with this Article III shall thereafter look only to Parent for payment of cash, shares of Parent Common Stock, cash in lieu of any fractional shares and unpaid dividends and distributions on Parent Common Stock deliverable in respect of each share of Company Common Stock such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon; provided that subject to applicable state escheat law or unclaimed property law, any holder of a certificate formerly representing shares of Company Common Stock later surrenders such certificate (or customary affidavits and indemnification regarding a loss or destruction of such certificate) to the Parent shall, upon acceptance thereof, be entitled to receive a certificate representing Parent Common Stock and/or cash into which the shares of Common Stock shall have been converted pursuant to this agreement as well as cash in lieu of any fractional shares of Parent Common Stock to which such holder would otherwise be entitled and any unpaid dividends and distributions on Parent Common Stock to which owner is entitled.

(g) Withholding Rights. Parent or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as Parent or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by Parent or the Exchange Agent.

3.07. Anti-Dilution Provisions. In the event Parent or the Company changes (or establishes a record date for changing) the number of shares of Parent Common Stock or Company Common Stock issued and outstanding prior to the Effective Date as a result of a stock split, stock dividend, recapitalization or similar transaction with respect to the outstanding Parent Common Stock or Company Common Stock, as the case may be, and the record date therefor shall be prior to the Effective Date, the amount of Cash Consideration and Stock Consideration per share shall be proportionately adjusted. If, between the date hereof and the Effective Time, Parent shall merge, be acquired or consolidate with, by or into any other corporation (a “Business Combination”) and the terms thereof shall provide that Parent Common Stock shall be converted into or exchanged for the shares of any other corporation or entity, then provision shall be made as part of the terms of such Business Combination so that shareholders of the Company who would be entitled to receive shares of Parent Common Stock pursuant to this Agreement shall be entitled to receive, in lieu of each share of Parent Common Stock issuable to such shareholders as provided herein, the same kind and amount of securities or assets as shall be distributable upon such Business Combination with respect to one share of Parent Common Stock (provided that nothing herein shall be construed so as to release the acquiring entity in any such Business Combination from its obligations under this Agreement as the successor to Parent).

3.08. Dissenters’ Rights. (a) Any Dissenting Shareholder who shall be entitled to be paid the value of such shareholder’s shares of Company Common Stock, as provided in Section 23B.13 of the WBCA, shall not be entitled to Merger Consideration in respect thereof provided for under Section 3.01 unless and until such Dissenting Shareholder shall have failed to perfect or shall have effectively withdrawn or lost such Dissenting Shareholder’s right to dissent from the Merger under the WBCA, and shall be entitled to receive only the payment provided for by Section 23B.13 of the WBCA with respect to such Dissenters’ Shares.

(b) If any Dissenting Shareholder shall fail to perfect or shall have effectively withdrawn or lost such right to dissent, each share of Company Common Stock of such Dissenting Shareholder shall be deemed to be an Undesignated Share and shall be converted at Parent’s discretion into the right to receive the Cash Consideration or the Stock Consideration.

3.09. Company Stock Options. (a) At the Effective Time, each Company Stock Option shall be converted into a fully vested option to acquire a number of shares of Parent Common Stock equal to the product (rounded down to the nearest whole number) of (x) the number of Company Common Stock subject to the Company Stock Option immediately prior to the Effective Time and (y) the Exchange Ratio (defined below), at an exercise price per share

(rounded up to the nearest whole cent) equal to (A) the exercise price per Company Common Stock of such Company Stock Option immediately prior to the Effective Time divided by (B) the Exchange Ratio; provided, however, that the exercise price and the number of shares of Parent Common Stock purchasable pursuant to the Company Stock Options shall be determined in a manner consistent with the requirements of Section 409A of the Code; provided, further, that in the case of any Company Stock Option to which Section 422 of the Code applies, the exercise price and the number of shares of Parent Company Stock purchasable pursuant to such option shall be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 424(a) of the Code. Except as specifically provided above, following the Effective Time, each Company Stock Option shall continue to be governed by the same terms and conditions as were applicable under such Company Stock Option immediately prior to the Effective Time. For purposes of this Agreement, the “Exchange Ratio” shall be equal to the fraction having a numerator equal to the Company Common Stock Value and having a denominator equal to the Parent Measuring Price.

(b) Within fifteen (15) days following the Effective Time, Parent will prepare and file with the SEC a Registration Statement on Form S-8 covering shares of Parent Common Stock to be issued upon the exercise of stock options assumed by Parent pursuant to this Section 3.09.

(c) At or prior to the Effective Time, the Company, Company Board and the compensation committee of the Company Board, as applicable, shall adopt any resolutions and take any actions which are necessary to effectuate the provisions of this Section 3.09. The Company shall take all actions necessary to ensure that, from and after the Effective Time, Parent will not be required to deliver Company Common Stock or other capital stock of the Company to any Person pursuant to or in settlement of Company Stock Options after the Effective Time.

Each of the Company and the Company Subsidiaries has paid all assessments made or imposed by any Regulatory Authority.

(ii) The Company and the Company Subsidiaries have not been advised by, and do not have any Knowledge of facts which could give rise to an advisory notice by, any Regulatory Authority that such Regulatory Authority is contemplating issuing or requesting (or is considering the appropriateness of issuing or requesting) any such order, decree, agreement, memorandum of understanding, commitment letter, supervisory letter or similar submission.

(k) Material Contracts; Defaults. Except as set forth in Section 5.03(k) of the Company Disclosure Schedule, to the Knowledge of the Company and the Company Subsidiaries, neither the Company nor any Company Subsidiary is a party to, bound by or subject to any agreement, contract, arrangement, commitment or understanding (whether written or oral) (i) that is (or would be if the Company were a registrant under the Exchange Act) a “material contract” within the meaning of Item 601(b)(10) of the SEC’s Regulation S-K with respect to such entity or (ii) that materially restricts the conduct of business by the Company or by any Company Subsidiary.

No power of attorney or similar authorization given directly or indirectly by the Company or by any Company Subsidiary is currently outstanding. Section 5.03(k) of the Company Disclosure Schedule sets forth a true and complete list of all third party consents or waivers required to be obtained so as not to be in default under any contract, agreement, commitment, arrangement, lease, insurance policy or other instrument to which the Company is a party as a result of the transactions contemplated hereby.

(m) Employee Benefit Plans. (i) All benefit and compensation plans, contracts, policies (including bank owned life insurance policies, or “BOLI”) or arrangements covering current or former employees of the Company and any Company Subsidiary (collectively, the “Employees”) and current or former directors of the Company and any Company Subsidiary including, but not limited to, “employee benefit plans” within the meaning of Section 3(3) of ERISA, and deferred compensation, stock option, stock purchase, stock appreciation rights, stock based, incentive and bonus plans (the “Benefit Plans”), are set forth in Section 5.03(m) to the Company Disclosure Schedule and each Benefit Plan which has received a favorable opinion letter from the Internal Revenue Service National Office, including any master or prototype plan, has been separately identified. True and complete copies of all Benefit Plans including, but not limited to, any trust instruments and insurance contracts forming a part of any Benefit Plans and all amendments thereto have been provided or made available to Parent.

(ii) All Benefit Plans, to the extent subject to ERISA, are in substantial compliance with ERISA, the Code and other applicable law. Each Benefit Plan which is an “employee pension benefit plan” within the meaning of Section 3(2) of ERISA (“Pension Plan”) and which is intended to be qualified under Section 401(a) of the Code, has received a favorable determination letter from the Internal Revenue Service covering all tax law changes prior to the Economic Growth and Tax Relief Reconciliation Act of 2001, and neither the Company nor any Company Subsidiary is aware of any circumstances likely to result in revocation of any such favorable determination letter or the loss of the qualification of such Pension Plan under Section 401(a) of the Code. There is no material pending or threatened litigation relating to the Benefit Plans. Neither the Company nor any Company Subsidiary has engaged in a transaction with respect to any Benefit Plan or Pension Plan that, assuming the taxable period of such transaction expired as of the date hereof, could subject the Company or any Company Subsidiary to a tax or penalty imposed by either Section 4975 of the Code or Section 502(i) of ERISA in an amount which would be material. Neither the Company nor any Company Subsidiary has incurred or reasonably expects to incur a material tax or penalty imposed by Section 4980F of the Code or Section 502 of ERISA.

(iii) No liability under Subtitle C or D of Title IV of ERISA has been or is expected to be incurred by the Company with respect to any ongoing, frozen or terminated “single-employer plan”, within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by the Company or any Company Subsidiary, or the single-employer plan of any entity which is considered one employer with the Company under Section 4001 of ERISA or Section 414 of the Code (an “ERISA Affiliate”). Neither

the Company nor any Company Subsidiary has incurred, nor do they expect to incur, any withdrawal liability with respect to a multiemployer plan under Subtitle E of Title IV of ERISA (regardless of whether based on contributions of an ERISA Affiliate). No notice of a “reportable event”, within the meaning of Section 4043 of ERISA for which the reporting requirement has not been waived or extended, other than pursuant to Pension Benefit Guaranty Corporation (“PBGC”) Reg. Section 4043.33 or 4043.66, has been required to be filed for any Pension Plan or by any ERISA Affiliate within the 12-month period ending on the date hereof or will be required to be filed in connection with the transaction contemplated by this Agreement. No notices have been required to be sent to participants and beneficiaries or the PBGC under Section 302 or 4011 of ERISA or Section 412 of the Code.

(iv) All contributions required to be made under the terms of any Benefit Plan have been timely made and all obligations in respect of each Benefit Plan have been properly accrued. Neither any Pension Plan nor any single-employer plan of an ERISA Affiliate has an “accumulated funding deficiency” (whether or not waived) within the meaning of Section 412 of the Code or Section 302 of ERISA and no ERISA Affiliate has an outstanding funding waiver. Neither any Pension Plan nor any single-employer plan of an ERISA Affiliate has been required to file information pursuant to Section 4010 of ERISA for the current or most recently completed plan year. It is not reasonably anticipated that required minimum contributions to any Pension Plan under Section 412 of the Code will be materially increased by application of Section 412(l) of the Code. Neither the Company nor any Company Subsidiary has provided, nor is either required to provide, security to any Pension Plan or to any single-employer plan of an ERISA Affiliate pursuant to Section 401(a)(29) of the Code.

(v) Under each Pension Plan which is a single-employer plan, as of the last day of the most recent plan year ended prior to the date hereof, the actuarially determined present value of all “benefit liabilities,” within the meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the actuarial assumptions contained in the Pension Plan’s most recent actuarial valuation), did not exceed the then current value of the assets of such Pension Plan, and there has been no material change in the financial condition of such Plan since the last day of the most recent plan year.

(vi) Neither the Company nor any Company Subsidiary has any obligations for retiree health and life benefits under any Benefit Plan. Any Benefit Plan may be amended or terminated at any time by the Company or any Company Subsidiary, as the case may be, at any time without incurring any liability thereunder.

(vii) There has been no amendment to, announcement by the Company or any Company Subsidiary relating to, or change in employee participation or coverage under, any Benefit Plan which would increase materially the expense of maintaining such plan above the level of expense incurred therefor for the most recent fiscal year. Except as set forth in Section 5.03(m)(vii) to the Company Disclosure Schedule, none of the execution of this Agreement, shareholder approval of this Agreement or consummation of the

transactions contemplated by this Agreement will (A) entitle any employees of the Company or any Company Subsidiary to severance pay or any increase in severance pay upon any termination of employment after the date hereof, (B) accelerate the time of payment or vesting or trigger any payment or funding (through a grantor trust or otherwise) of compensation or benefits under, increase the amount payable or trigger any other material obligation pursuant to, any of the Benefit Plans, (C) result in any breach or violation of, or a default under, any of the Benefit Plans, (D) limit or restrict the right of the Company or, after the consummation of the transactions contemplated hereby, Parent to merge, amend or terminate any of the Benefit Plans or (E) result in any payment under any Benefit Plans which would not be deductible under Sections 162(m) or 280G of the Code.

(n) Labor Matters. Neither the Company nor any Company Subsidiary is a party to or bound by any collective bargaining agreement, contract or other agreement or understanding with a labor union or labor organization, nor is either the Company or any Company Subsidiary the subject of a proceeding asserting that it has committed an unfair labor practice (within the meaning of the National Labor Relations Act) or seeking to compel the Company or such Company Subsidiary to bargain with any labor organization as to wages or conditions of employment, nor is there any strike or other labor dispute involving it or, to the Company’s or any Company Subsidiary’s Knowledge, threatened, nor is the Company or any Company Subsidiary aware of any activity involving its employees seeking to certify a collective bargaining unit or engaging in other organizational activity.

6.03. Registration Statement. (a) Parent agrees to prepare a registration statement on Form S-4 or other applicable form (the “Registration Statement”) to be filed by Parent with the SEC in connection with the issuance of Parent Common Stock in the Merger (including the proxy statement and prospectus and other proxy solicitation materials of the Company and Parent constituting a part thereof (the “Proxy Statement”) and all related documents). The Company shall prepare and furnish such information relating to it and its directors, officers and shareholders as may be reasonably required in connection with the above referenced documents based on its Knowledge of and access to the information required for said documents, and the Company and its counsel will cooperate with and assist Parent and its counsel in the preparation of the Proxy Statement. The Company agrees to cooperate with Parent and Parent’s counsel, financial advisor and accountants in requesting and obtaining appropriate opinions, consents and letters from its financial advisor and independent auditor in connection with the Registration Statement and the Proxy Statement. Provided that the Company has cooperated as described above, Parent agrees to file, or cause to be filed, the Registration Statement and the Proxy Statement with the SEC as promptly as reasonably practicable but in no event later than 60 days after the date hereof.

After the Registration Statement is declared effective under the Securities Act, the Company shall promptly mail at its expense the Proxy Statement to its shareholders.

(b) Each of the Company and Parent agrees that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in the Registration Statement shall, at the time the Registration Statement and each amendment or supplement thereto, if any, becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading and the Proxy Statement and any amendment or supplement thereto shall not, at the date of mailing to shareholders and at the time of the Company Meeting contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. Each of the Company and Parent further agrees that if such party shall become aware prior to the Effective Date of any information furnished by such party that would cause any of the statements in the Registration Statement or the Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, it shall promptly inform the other party thereof and to take the necessary steps to correct the Registration Statement or the Proxy Statement.

(c) Parent agrees to advise the Company, promptly after Parent receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, of the issuance of any stop order or the suspension of the qualification of Parent Common Stock for offering or sale in any jurisdiction, of the initiation or, to the extent Parent is aware thereof, threat of any proceeding for any such purpose, or of any request by the SEC for the amendment or supplement of the Registration Statement or for additional information.

6.04. Press Releases. The Company and Parent shall consult with each other before issuing any press release with respect to the Merger or this Agreement and neither shall issue any such press release or make any such public statements without the prior consent of the other party, which shall not be unreasonably withheld; provided, however, that a party may, without the prior consent of the other party (but after such consultation, to the extent practicable in the circumstances), issue such press release or make such public statements as may upon the advice of outside counsel be required by law or the rules or regulations of Nasdaq. The Company and Parent shall cooperate to develop all public announcement materials and make appropriate management available at presentations related to the transactions contemplated by this Agreement as reasonably requested by the other party.

6.05. Access; Information. (a) Each of the Company and Parent agrees that upon reasonable notice and subject to applicable laws relating to the exchange of information, it shall afford the other party and the other party’s officers, employees, counsel, accountants and other authorized representatives such access during normal business hours throughout the period prior to the Effective Time to the books, records (including, without limitation, Tax Returns and work papers of independent auditors), properties and personnel and to such other information as the other party may reasonably request and, during such period, the Company shall, as promptly as is reasonably practicable, furnish to Parent all information concerning its business, properties and personnel as Parent may reasonably request.

(b) Without limiting the generality of Section 6.05(a), prior to the Effective Time, Parent and Parent’s respective representatives shall have the right, subject to the notice provision set forth in Section 6.05(a), to conduct a review to determine (i) that the assets, books, records and operations of the Company are in satisfactory condition and will not in a material way adversely impact Parent after consummation of the transactions contemplated hereby and (ii) the accuracy of the representations and warranties and the satisfaction of the conditions to closing as provided hereunder.

(c) The Company agrees that, subject to applicable laws, it shall cooperate in good faith with Parent on mutually agreed operating issues which the parties agree have priority.

(d) Parent agrees that, upon reasonable notice and subject to applicable laws relating to the exchange of information, it shall afford the Company and its authorized representatives such access to Parent’s personnel as the Company may reasonably request.

(e) Each party agrees that it will not, and will cause its representatives not to, use any information obtained pursuant to this Section 6.05 (as well as any other information obtained

prior to the date hereof in connection with the entering into of this Agreement) for any purpose unrelated to the consummation of the transactions contemplated by this Agreement. Subject to the requirements of law, each party shall keep confidential, and shall cause its representatives to keep confidential, all information and documents obtained pursuant to this Section 6.05 (as well as any other information obtained prior to the date hereof in connection with the entering into of this Agreement) unless such information (i) was already known to such party, (ii) becomes available to such party from other sources not known by such party to be bound by a confidentiality obligation, (iii) is disclosed with the prior written approval of the party to which such information pertains or (iv) is or becomes readily ascertainable from publicly available sources. In the event that this Agreement is terminated or the transactions contemplated by this Agreement shall otherwise fail to be consummated, each party shall promptly cause all copies of documents or extracts thereof containing information and data as to another party hereto to be returned to the party which furnished the same. No investigation by any party of the business and affairs of any other party shall affect or be deemed to modify or waive any representation, warranty, covenant or agreement in this Agreement, or the conditions to any party’s obligation to consummate the transactions contemplated by this Agreement.

(f) Notwithstanding anything to the contrary in this Agreement, the Company, Company Subsidiaries, Parent and Parent Subsidiaries (and each of their respective employees, representatives or other agents) may disclose to any and all Persons, without limitation of any kind, the “tax treatment” and “tax structure” of the transaction and all materials of any kind (including opinions or other tax analyses) that are provided to any such party relating to such “tax treatment” or “tax structure”. For the purposes of this Section 6.05(f), “tax treatment” and “tax structure” shall have the meaning set forth in Section 1.6011-4(c)(7) & (8) of the United States Treasury Regulations.

6.06. Affiliates. The Company shall cooperate with Parent to identify those Persons who may be deemed to be “affiliates” of the Company within the meaning of Rule 145 promulgated by the SEC under the Securities Act (such Persons being “Company Affiliates”). The Company shall use its reasonable best efforts to cause each Person so identified to deliver to Parent, prior to the Company Meeting, a written agreement (which agreement shall be substantially in the form of Exhibit C). Parent shall not be required to maintain the effectiveness of the S-4 Registration Statement or any other registration statement under the Securities Act for the purposes of resale of Parent Common Stock by such affiliates received in the Merger and the certificates representing Parent Common Stock received by such affiliates shall bear a customary legend regarding applicable Securities Act restrictions and the provisions of this Section.

6.07. [Reserved.]

6.08. Acquisition Proposals. The Company agrees that its officers or directors shall not, and that it shall direct and use its best efforts to cause any of the Company Subsidiaries and the Company Subsidiaries’ employees, agents and representatives not to, directly or indirectly, initiate, solicit, encourage or otherwise facilitate any inquiries or the making of any proposal or offer with respect to a merger, reorganization, share exchange, consolidation or similar transaction involving, or any purchase of all or substantially all of the assets of the Company or

more than 10% of the outstanding equity securities of the Company (any such proposal or offer being hereinafter referred to as an “Acquisition Proposal”). The Company further agrees that neither the Company nor any of the Company Subsidiaries nor any of their respective officers or directors shall, and that the Company shall direct and use its reasonable best efforts to cause any of the Company Subsidiaries and any of the Company Subsidiaries’ employees, agents and representatives not to, directly or indirectly, engage in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any Person relating to an Acquisition Proposal, or otherwise facilitate any effort or attempt to make or implement an Acquisition Proposal; provided, however, that nothing contained in this Agreement shall prevent the Company or the Company Board from (A) complying with its disclosure obligations under federal or state law; (B) providing information in response to a request therefor by a Person who has made an unsolicited bona fide written Acquisition Proposal if the Company Board receives from the Person so requesting such information an executed confidentiality agreement; (C) engaging in any negotiations or discussions with any Person who has made an unsolicited bona fide written Acquisition Proposal; or (D) recommending such an Acquisition Proposal to the shareholders of the Company, if and only to the extent that, (i) in each such case referred to in clause (B), (C) or (D) above, the Company Board determines in good faith (after consultation with outside legal counsel) that such action is, in the absence of the foregoing proscriptions, necessary in order for its directors to comply with their respective fiduciary duties under applicable law and (ii) in the case referred to in clause (D) above, the Company Board determines in good faith (after consultation with its financial advisor) that such Acquisition Proposal, if accepted, is reasonably likely to be consummated, taking into account all legal, financial and regulatory aspects of the proposal and the Person making the proposal and would, if consummated, result in a transaction more favorable to the Company’s shareholders than the Merger. The Company agrees that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any Acquisition Proposals. The Company agrees that it will notify Parent immediately if any such inquiries, proposals or offers are received by, any such information is requested from, or any such discussions or negotiations are sought to be initiated or continued with, any of its representatives.

Each of Parent and the Company shall have the right to review in advance, and to the

extent practicable each shall consult with the other, in each case subject to applicable laws relating to the exchange of information, with respect to all material written information submitted to any third party or any Governmental Authority in connection with the transactions contemplated by this Agreement. In exercising the foregoing right, each of the parties agrees to act reasonably and as promptly as practicable. Each party hereto agrees that it shall consult with the other party hereto with respect to the obtaining of all material permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary or advisable to consummate the transactions contemplated by this Agreement and each party shall keep the other party apprised of the status of material matters relating to completion of the transactions contemplated hereby.

6.11. Indemnification. (a) Following the Effective Time, Parent shall indemnify, defend and hold harmless each present and former director and officer of the Company and the Company Subsidiaries (each, an “Indemnified Party”) against all costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities (collectively, “Costs”) incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of actions or omissions occurring at or prior to the Effective Time (including, without limitation, the transactions contemplated by this Agreement, or any related agreement, but excluding any Costs arising out of any violation or alleged violation of the Exchange Act or the rules and regulations thereunder with respect to insider trading) to the fullest extent that the Company is permitted to indemnify (and advance expenses to) its directors or officers under the WBCA, the Company Articles and the Company By-Laws as in effect on the date hereof; provided that any determination required to be made with respect to whether an officer’s or director’s conduct complies with the standards set forth under the WBCA, the Company Articles and the Company By-Laws shall be made by independent counsel selected by Parent and reasonably acceptable to the Indemnified Party.

(b) For a period of three years from the Effective Time, Parent shall use its commercially reasonable efforts to provide that portion of director’s and officer’s liability insurance that serves to reimburse the present and former officers and directors (determined as of the Effective Time) of the Company (as opposed to the portion that serves to reimburse the Company) with respect to claims against such directors and officers arising from facts or events which occurred before the Effective Time, which insurance shall contain at least the same coverage and amounts, and contain terms and conditions no less advantageous, as that coverage currently provided by the Company; provided, however, that in no event shall Parent be required to expend on an annual basis more than 200% of the current amount expended on an annual basis by the Company (the “Insurance Amount”) to maintain or procure such directors and officers insurance coverage; provided, further, that if Parent is unable to maintain or obtain the insurance called for by this Section 6.11(b), Parent shall use its commercially reasonable efforts to obtain

as much comparable insurance as is available for the Insurance Amount; provided, further, that officers and directors of the Company may be required to make application and provide customary representations and warranties to Parent’s insurance carrier for the purpose of obtaining such insurance.

(c) Any Indemnified Party wishing to claim indemnification under Section 6.11(a), upon learning of any claim, action, suit, proceeding or investigation described above, shall promptly notify Parent thereof; provided that the failure so to notify shall not affect the obligations of Parent under Section 6.11(a) unless and to the extent that Parent is actually prejudiced as a result of such failure.

(d) If Parent or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of Parent shall assume the obligations set forth in this Section 6.11.

6.12. Benefit Plans. (a) From and after the Effective Time, Parent shall provide former employees of the Company or the Company Bank who remain as employees of Parent or any Parent Subsidiary with pension and welfare benefits under employee benefit plans no less favorable in the aggregate than those provided to similarly situated employees of Parent or its Subsidiaries, as the case may be. Parent shall cause each employee benefit plan, program, policy or arrangement of Parent in which employees of the Company or the Company Bank are eligible to participate to take into account for purposes of eligibility and vesting thereunder except for purposes of qualifying for subsidized early retirement benefits or to the extent it would result in a duplication of benefits, service by employees of the Company and its Subsidiaries as if such service were with Parent, to the same extent such service was credited under a comparable plan of the Company. Notwithstanding the foregoing, nothing contained herein shall obligate Parent or any Parent Subsidiary to (i) maintain any particular Benefit Plan or (ii) retain the employment of any particular employee.

(b) If employees of the Company or the Company Bank become eligible to participate in a medical, dental or health plan of Parent, Parent shall cause, to the extent practicable, each such plan to (i) waive any preexisting condition limitations to the extent such conditions were covered under the applicable medical, health or dental plans of the Company or the Company Bank, (ii) honor under such plans any deductible, co-payment and out-of-pocket expenses incurred by the employees and their beneficiaries during the portion of the calendar year prior to such participation and (iii) waive any waiting period limitation or evidence of insurability requirement which would otherwise be applicable to such employee on or after the Effective Time to the extent such employee had satisfied any similar limitation or requirement under an analogous plan prior to the Effective Time.

(c) If Parent determines that one or more Benefit Plans of the Company or any Company Subsidiary should be amended, modified or terminated prior to the Effective Time, the Company or any Company Subsidiary, as the case may be, shall take, or cause to be taken, all

actions reasonably requested by Parent to so amend, modify or terminate and, if reasonably necessary or appropriate, obtain applicable determination letters or other required approvals from the IRS and/or the Department of Labor, as appropriate, in connection with such action.

(d) Effective as of no later than the day immediately preceding the Effective Date, the Company shall terminate the 401(k) Plan unless Parent provides written notice to the Company that the 401(k) Plan shall not be terminated. If the 401(k) Plan is terminated pursuant to the previous sentence, Parent will offer the Plan participants an election to roll-over their Plan accounts into the Parent’s 401(k) Plan, or the 401(k) Plan may distribute its nets assets to participants, former participants and beneficiaries in accordance with the 401(k) Plan and applicable laws. If the 401(k) Plan is terminated pursuant to the first sentence of this Section 6.12(d), the Company shall provide Parent with evidence that the 401(k) Plan has been terminated (effective as of no later than the day immediately preceding the Effective Date) pursuant to resolutions of the Company Board. The form and substance of such resolutions shall be subject to the review and reasonable and timely approval of Parent. The Company also shall take such other actions in furtherance of terminating the 401(k) Plan as Parent may reasonably require.

(e) Employees of Company and Company Bank will also participate in the employee stock option plan(s) of Parent and Parent Bank to a comparable extent and at a comparable level to those similarly situated employees of Parent and Parent Bank. Employees of Company and Company Bank will be entitled to carry over unused vacation days and sick leave accrued as of the Effective Time.

(f) As of the Effective Time, Parent shall assume and honor and cause Parent Bank to assume and to honor in accordance with their terms the agreements of the Company and/or Company Bank with respect to any benefits or payments or restricted stock plan awards triggered by a change of control of the Company or Company Bank set forth in Section 6.12(f) of the Company Disclosure Schedule (the “CIC Agreements”). Parent acknowledges and agrees that the Merger will constitute a merger, sale or a change of control of Company and Company Bank for all purposes under the CIC Agreements. The provisions of this Section 6.12(f) are intended to be for the benefit of, and shall be enforceable by, each director, officer or employee that is a party to any such agreement.

6.13. Non-Competition and Non-Solicitation Agreements. Each director of the Company shall, simultaneously with the execution and delivery hereof, execute and deliver to Parent a Non-Competition and Non-Solicitation Agreement substantially in the form of Exhibit B hereto.

6.14. Notification of Certain Matters. Each of the Company and Parent shall give prompt notice to the other of any fact, event or circumstance known to it that (i) is reasonably likely, individually or taken together with all other facts, events and circumstances known to it, to result in any Material Adverse Effect with respect to it or (ii) would cause or constitute a material breach of any of its representations, warranties, covenants or agreements contained herein.

6.15. Human Resources Issues. The Company agrees to cooperate with Parent with respect to any formal meetings or interviews with one or more employees called or arranged by the Company and held for the purpose of discussing the transactions contemplated by this Agreement or their effect on such employees, with Parent given the opportunity to participate in such meetings or interviews. This section is not intended to apply to casual conversations about the transaction or informal meetings initiated by employees, or to prohibit discussion in general, but rather to allow Parent a role in the formal presentation of the transaction to employees, and an opportunity to participate in the significant, formal meetings at which the transaction is explained and discussed. Additionally, prior to making any written or oral communications to the directors, officers or employees of the Company or any of its Subsidiaries pertaining to compensation or benefit matters that are affected by the transactions contemplated by this Agreement, the Company shall provide Parent with a copy of the intended communication, Parent shall have a reasonable period of time to review and comment on the communication, and Parent and the Company shall cooperate in providing any such mutually agreeable communication.

6.16. Assistance with Third-Party Agreements. (a) The Company shall cooperate with and use all commercially reasonable efforts to assist Parent in (i) gaining access to and obtaining any required consents from all of its third-party vendors, landlords of all of the Company’s leased properties and other parties to material agreements, promptly after the date of this Agreement, and (ii) obtaining the cooperation of such third parties in a smooth transition in accordance with Parent’s timetable at or after the Effective Time of the Merger. The Company shall cooperate with Parent in minimizing the extent to which any contracts will continue in effect following the Effective Time of the Merger, in addition to complying with the prohibition of Section 4.01(l) hereof.

(b) Without limiting Section 6.16(a), the Company shall use all reasonable efforts to provide data processing and other processing support or outside contractors to assist Parent in performing all tasks reasonably required to result in a successful conversion of the Company’s and the Company Subsidiaries’ data and other files and records to Parent’s production environment, when requested by Parent and sufficient to ensure that a successful conversion can occur at such time as Parent requests on or after the Effective Time of the Merger. Among other things, the Company shall:

(i) cooperate with Parent to establish a mutually agreeable project plan to effectuate the conversion;

(ii) use commercially reasonable efforts to have the Company’s and the Company Subsidiaries’ outside contractors continue to support both the conversion effort and their needs until the conversion can be established;

(iv) provide reasonable access to personnel at corporate headquarters, data and other processing centers, all branches and, with the consent of outside contractors, at outside contractors, to enable the conversion effort to be completed on schedule; and

(v) to the extent reasonably practicable, give notice of termination, conditioned upon the completion of the transactions contemplated hereby, of the contracts of outside data and other processing contractors or other third-party vendors when directed to do so by Parent.

Parent agrees that all actions taken pursuant to this Section 6.16 shall be taken in a manner intended to minimize disruption to the customary business activities of the Company.

Neither the Company nor the Company Bank shall take any action that would prevent performance of the agreement of Bank Merger or any other transactions contemplated in connection with the Bank Merger; provided, however, that Parent and Parent Bank may at any time prior to the time the Bank Merger becomes effective change the method of effecting the combination of Parent Bank with the Company Bank if and to the extent Parent or Parent Bank deems such change to be necessary, appropriate or desirable; provided, however, that no such change shall (i) alter or change the amount or kind of Merger Consideration to be issued to the holders of the Company Common Stock as provided for in this Agreement, (ii) adversely affect the tax treatment of the Company’s shareholders as a result of receiving the Merger Consideration, including, without limitation, any adverse effect upon the tax-free treatment, (iii) materially impede or delay consummation of the transactions contemplated by this Agreement, or (iv) otherwise be materially prejudicial to the interests of the shareholders of the Company.

6.18. Shareholder Agreements. Each Shareholder, as a shareholder of Company Common Stock, shall execute and deliver to Parent simultaneously with the execution of this Agreement a Shareholder Agreement substantially in the form of Exhibit A hereto, committing each such person, among other things, to vote his or her shares of Company Common Stock in favor of the principal terms of the Merger at the Company Meeting and to certain representations and covenants.

6.19. Additional Agreements. In case at any time after the Effective Time of the Merger any further action is necessary or desirable to carry out the purposes of this Agreement or to vest Parent or Parent Bank with full title to all properties, assets, rights, approvals, immunities and franchises of the Company and the Company Subsidiaries, the proper officers and directors of each party to this Agreement shall take all necessary or appropriate action.

6.20. Pre-Closing Adjustments. At or before the Effective Time of the Merger, the Company and any of the Company Subsidiaries shall make such accounting entries or

adjustments, including additions to their ALLL and charge-offs of loans, as Parent shall direct as a result of its on-going review of the Company and any of the Company Subsidiaries (including its review of the information provided to it pursuant to Sections 6.05 and 6.15) or in order to implement its plans following the Effective Time or to reflect expenses and costs related to the Merger; provided, however, that unless the adjustment would otherwise be required by applicable law, rule or regulation, or by regulatory accounting principles and GAAP applied on a basis consistent with the financial statements of the Company, (a) the Company shall not be required to take such actions more than one day prior to the Effective Time of the Merger or prior to the time Parent agrees in writing that all of the conditions to its obligation to close as set forth in Section 7.02 have been satisfied or waived and each of the approvals in Section 7.01(b) have been received, and (b) no such adjustment shall (i) require any filing with any Governmental Authority, (ii) violate any law, rule or regulation applicable to Parent, (iii) otherwise materially disadvantage the Company if the Merger was not consummated or (iv) constitute or be deemed to be a breach, violation of or failure to satisfy any representation, warranty, covenant, condition or other provision of this Agreement or otherwise be considered in determining whether any such breach, violation or failure to satisfy shall have occurred.

6.21. Tax Treatment of the Merger. Parent and the Company intend that the Merger will be treated for U.S. federal income tax purposes as a reorganization qualifying under the provisions of Section 368(a) of the Code and that each of Parent and the Company will be a party to the reorganization within the meaning of Section 368(b) of the Code. Each party will (and will cause each of its Subsidiaries to) both before and after the Effective Time (i) use reasonable efforts to cause this Agreement to so qualify; (ii) refrain from taking any action that would reasonably be expected to cause this Agreement to fail to so qualify; and (iii) take the position for all purposes that this Agreement so qualifies.

6.22. Preservation of Insurance Claims. The Company will take, and will cause its Company Subsidiaries to take, all commercially reasonable action (including, without limitation, the making of claims and the giving of notices) pursuant to any of the insurance policies listed in Section 5.03(s) of the Company Disclosure Schedule in order to preserve all material rights thereunder with respect to all matters which could reasonably be expected to give rise to a claim thereunder prior to the Effective Time, and in any event, upon the reasonable request of Parent. The Company will, and will cause its Company Subsidiaries to, provide Parent with proof of such claim or notice in a form satisfactory to Parent.

(c) Delay. At any time prior to the Effective Time, by Parent or the Company if its Board of Directors so determines by vote of a majority of the members of its entire Board, in the event that the Merger is not consummated by June 30, 2006 except to the extent that the failure of the Merger then to be consummated arises out of or results from the knowing action or

inaction of (i) such party, (ii) Parent Bank or the Company Bank (if Parent or the Company, respectively, is the party seeking to terminate) or (iii) any of the Shareholders (if the Company is the party seeking to terminate), which action or inaction is in violation of its obligations under this Agreement or, in the case of the Shareholders, his, her or its obligations under the relevant Shareholder Agreement.

(b) (i) If this Agreement is terminated by the Company pursuant to Section 8.01(b) (if Parent is the breaching party) or because any Regulatory Approval is not obtained by March 31, 2006 because Parent or Parent Bank is not or will not be well-capitalized under applicable federal banking laws and regulations, then upon such termination, Parent shall pay to the

Company a termination fee (a “Termination Fee”), representing liquidated damages, of $1,000,000.

(ii) If this Agreement is terminated by Company or Parent as a result of the failure of the other party (the “Failing Party”) to obtain any required approval of its shareholders arising out of or related to the transactions contemplated by this Agreement, then upon such termination, the Failing Party shall pay to the other party a Termination Fee, representing liquidated damages, of $1,000,000.

(c) If this Agreement is terminated by Parent as a result of the Company’s failure to obtain shareholder approval pursuant to Section 8.01(d)(ii) or pursuant to Section 8.01(f) or pursuant to Section 8.01(b) (if the Company or a Shareholder is the breaching party), then upon such termination the Company shall pay to Parent a Termination Fee, representing liquidated damages, of $1,000,000.

(d) Anything in Section 8.02(c) to the contrary notwithstanding, if this Agreement is terminated after a bona fide Acquisition Proposal for the Company shall have been publicly disclosed, or any person or entity shall have publicly disclosed a bona fide intention (whether or not conditional) to make an Acquisition Proposal and the Company has determined to pursue such Acquisition Proposal:

(i) by the Company or Parent pursuant to Section 8.01(c) or Section 8.01(d)(ii);

(ii) by the Company or Parent pursuant Section 8.01(e) or Section 8.01(f); or

(e) Any Termination Fee that becomes payable to a party pursuant to this Section 8.02 shall be paid within two Business Days of termination by wire transfer of immediately available funds to an account designated by the other party. Payment of a Termination Fee to a party pursuant to this Section 8.02 shall be the sole and exclusive remedy of the party receiving the payment against the paying party with respect to the breach of any covenant or agreement giving rise to such payment. Anything to the contrary in this Agreement notwithstanding, however, a party shall not be required to pay more than one Termination Fee of $1,000,000 to the other party under any circumstance.

(f) The Company and Parent agree that the agreements contained in paragraphs (b), (c) and (d) above are an integral part of the transactions contemplated by this Agreement, that without such agreements the Company and Parent would not have entered into this Agreement, and that such amounts do not constitute a penalty. If the party owing the Termination Fee fails to pay the other party the amounts due under paragraph (b) or (c) or (d) above within the time periods specified in paragraph (e) above, the party owing the Termination Fee shall pay all costs and expenses incurred by the other party in connection with any action, including the filing of any lawsuit, taken to collect payment of such amounts, together with interest on the amount of any such unpaid amounts at the publicly announced prime rate of Bank of America, N.A. from the date such amounts were required to be paid.

(a) Shareholder hereby agrees to vote all of the Shares held by Shareholder (i) in favor of the principal terms of the Merger, the Merger Agreement and the transactions contemplated by the Merger Agreement; (ii) against any action or agreement that would result in a breach in any material respect of any covenant, representation or warranty or any other obligation or agreement of Columbia Trust under the Merger Agreement; and (iii) except with the prior written consent of AmericanWest, against the following actions (other than the Merger and the transactions contemplated by the Merger Agreement): (A) any extraordinary corporate transactions, such as a merger, consolidation or other business combination involving Columbia Trust or Columbia Trust Bank; (B) any sale, lease or transfer of a material amount of the assets of Columbia Trust or Columbia Trust Bank; (C) any change in the majority of the board of directors of Columbia Trust; (D) any material change in the present capitalization of Columbia Trust; (E) any amendment of Columbia Trust’s Articles of Incorporation or the equivalent organizational documents of Columbia Trust Bank; (F) any other material change in the corporate structure or business of Columbia Trust or Columbia Trust Bank; or (G) any other action which is intended, or could reasonably be expected, to impede, interfere with, delay, postpone, discourage or materially adversely affect the contemplated economic benefits to AmericanWest of the transactions contemplated by the Merger Agreement. Shareholder shall not enter into any agreement or understanding with any person or entity prior to the Termination Date (as defined below) to vote or give instructions after the Termination Date in any manner inconsistent with clauses (i), (ii) or (iii) of the preceding sentence.

(b) Shareholder hereby agrees not to (i) sell, transfer, assign or otherwise dispose of any of his or her Shares without the prior written consent of AmericanWest, other than Shares sold or surrendered to pay the exercise price of any stock options or to pay taxes or satisfy Columbia Trust’s withholding obligations with respect to any taxes resulting from such exercise or (ii) pledge, mortgage or encumber such Shares. Any permitted transferee of Shares must

become a party to this Shareholder Agreement and any purported transfer of Shares to a person or entity that has not become a party hereto shall be null and void.

3. Cooperation. Shareholder agrees that he or she will not directly or indirectly solicit any inquiries or proposals from any person relating to any proposal or transaction for the disposition of the business or assets of Columbia Trust or Columbia Trust Bank or the acquisition of voting securities of Columbia Trust or Columbia Trust Bank or any business combination between Columbia Trust or Columbia Trust Bank and any person other than AmericanWest and AmericanWest’s affiliates.

4. Shareholder Capacity. Shareholder is entering this Shareholder Agreement in his or her capacity as the record or beneficial owner of Shareholder’s Shares, and not in his or her capacity as a director of Columbia Trust or Columbia Trust Bank. Nothing in this Shareholder Agreement shall be deemed in any manner to limit the discretion of Shareholder to take any action, or fail to take any action, in his or her capacity as a director of Columbia Trust or Columbia Trust Bank, that may be required of Shareholder in the exercise of his or her duties and responsibilities as a director of Columbia Trust or Columbia Trust Bank.

5. Termination. The obligations of Shareholder hereunder shall terminate upon the consummation of the Merger. If the Merger is not consummated, the obligations of Shareholder hereunder shall terminate upon the termination of the Merger Agreement in accordance with its terms; provided that if, in the event of such termination, Columbia Trust is required to pay AmericanWest a termination fee specified in Section 8.02 of the Merger Agreement, those obligations set forth in Sections 2(a)(ii), 2(a)(iii)(G) and the last sentence of Section 2(a) hereof shall survive until Columbia Trust pays the specified termination fee to AmericanWest. In addition, if Columbia Trust is required to pay AmericanWest a termination fee specified in Section 8.02 of the Merger Agreement, Columbia Trust’s payment of the termination fee is the sole remedy for any breach of this Shareholder Agreement. The “Termination Date” for any particular provision hereunder shall be the date of termination of Shareholder’s obligations for such provision.

6. Specific Performance. Shareholder acknowledges that damages would be an inadequate remedy to AmericanWest for an actual or prospective breach of this Shareholder Agreement and that the obligations of Shareholder hereto shall be specifically enforceable.

7. Liability. Notwithstanding any breach of this Shareholder Agreement by Shareholder, if the Merger is completed on substantially the same terms as contemplated by the Merger Agreement, no liability will accrue to Shareholder.

8. Miscellaneous.

(a) Definitional Matters.

(i) Unless the context otherwise requires, “person” shall mean a corporation, association, partnership, joint venture, organization, business, individual, trust, estate or any other entity or group (within the meaning of Section 13(d)(3) of the Exchange Act).

(ii) All capitalized terms used but not defined in this Shareholder Agreement shall have the respective meanings that the Merger Agreement ascribes to such terms.

(iii) The descriptive headings herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Shareholder Agreement.

(b) Entire Agreement. This Shareholder Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all other prior agreements and understandings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof.

(c) Parties in Interest. This Shareholder Agreement shall be binding upon and inure solely to the benefit of each party hereto and their respective successors, assigns, heirs, executors, administrators and other legal representatives. Nothing in this Shareholder Agreement, expressed or implied, is intended to confer upon any other person any rights or remedies of any nature whatsoever under or by reason of this Shareholder Agreement.

(d) Assignment. This Shareholder Agreement shall not be assigned without the prior written consent of the other party hereto; provided, that AmericanWest may assign any of its rights and obligations hereunder to any of its affiliates.

(e) Modifications. This Shareholder Agreement shall not be amended, altered or modified in any manner whatsoever, except by a written instrument executed by the parties hereto.

(f) Severability. If any provision of this Shareholder Agreement or the application of such provision to any person or circumstances shall be held invalid or unenforceable by a court of competent jurisdiction, such provision or application shall be unenforceable only to the extent of such invalidity or unenforceability, and the remainder of the provision held invalid or unenforceable and the application of such provision to persons or circumstances, other than the

party as to which it is held invalid, and the remainder of this Shareholder Agreement, shall not be affected.

(g) Governing Law. This Shareholder Agreement shall be governed in all respects, including validity, interpretation and effect, by the laws of the State of Washington without regard to the conflicts of law principles thereof.

(h) Attorney’s Fees. The prevailing party or parties in any litigation, arbitration, mediation, bankruptcy, insolvency or other proceeding (“Proceeding”) relating to the enforcement or interpretation of this Shareholder Agreement may recover from the unsuccessful party or parties all reasonable fees and disbursements of counsel (including expert witness and other consultants’ fees and costs) relating to or arising out of (a) the Proceeding (whether or not it proceeds to judgment) and (b) any post-judgment or post-award proceeding including, without limitation, one to enforce or collect any judgment or award resulting from the Proceeding.

NON-COMPETITION AND NON-SOLICITATION AGREEMENT

Dated as of November 29, 2005

Between

and

AMERICANWEST BANCORPORATION

This NON-COMPETITION AND NON-SOLICITATION AGREEMENT (this “Agreement”) is dated as of November 29, 2005, by and between (“Director”) and AmericanWest Bancorporation, a Washington corporation (“AmericanWest”).

RECITALS

WHEREAS, Director is a director of Columbia Trust Bancorp, a Washington corporation with its principal place of business in Pasco, Washington (“Columbia Trust”); and

WHEREAS, AmericanWest and Columbia Trust have proposed to enter into the Agreement and Plan of Merger, dated as of the date hereof, by and between AmericanWest and Columbia Trust (the “Merger Agreement”), pursuant to which (i) Columbia Trust will merge with and into AmericanWest, (ii) Columbia Trust Bank, a Washington banking corporation and a wholly owned subsidiary of Columbia Trust (“Columbia Trust Bank”), will merge with and into AmericanWest Bank, a Washington banking corporation and a wholly owned subsidiary of AmericanWest (“AmericanWest Bank”), (iii) these transactions will constitute the sale of all or substantially all of Columbia Trust’s operating assets together with its goodwill pursuant to Washington Business Corporation Act Section 23B.11.060 and (iv) Director will receive such consideration as is set forth in the Merger Agreement for all of Director’s shares of common stock of Columbia Trust; and

WHEREAS, in order to induce AmericanWest to enter into the Merger Agreement and to minimize the risk that AmericanWest will lose the benefit of the goodwill and other assets being acquired, Director has agreed to restrict his activities in accordance with the terms and conditions of this Agreement;

-2-

NOW, THEREFORE, in consideration of the premises, and of the representations, warranties, covenants and agreements contained herein, and other good and valuable consideration, the receipt of and sufficiency of which the parties hereto hereby acknowledge, the parties hereto hereby agree as follows:

Non-Competition; Non-Solicitation; Confidentiality.

(a) Definitions. For purposes of this Agreement: “Company” means (i) Columbia Trust and Columbia Trust Bank prior to the Effective Time (as defined in the Merger Agreement), and (ii) at and following the Effective Time “Company” means AmericanWest and its affiliates. For purposes of this Agreement; “Restricted Business” shall mean any activity closely and customarily associated with commercial banking or the operation of an institution the deposits of which are insured by the Federal Deposit Insurance Corporation (but for purposes of clarification and removal of doubt, Restricted Business shall not include investment banking (including bond issues supported by bank or other letters of credit), investment advisory, broker-dealer or similar investment activities); “Restricted Territory” shall mean the geographic area consisting of Franklin, Benton and Yakima counties in the State of Washington; “Client” means any client or prospective client of the Company or its affiliates whose identity became known to Director solely in connection with his relationship with the Company or its affiliates; and “Solicit” means any direct or indirect communication of any kind, regardless of who initiates it, that in any way invites, advises, encourages or requests any person to take or refrain from taking any action.

(b) Agreement. Director agrees that for the period commencing on the Effective Date (as defined in the Merger Agreement) and ending on the date that is the 24-month anniversary of the Effective Date, Director shall not, directly or indirectly, engage in or have any ownership interest in, or participate in the financing, operation, management or control of, any person, firm, corporation or other entity or business that engages in a Restricted Business in a Restricted Territory; provided, that this provision shall not prohibit Director from owning bonds, preferred stock or up to five percent of the outstanding shares of common stock of any such entity if such common stock is publicly traded.

(c) No Solicitation. Director further agrees that he or she shall not, directly or indirectly, during the period commencing on the Effective Date and ending on the date that is the 24-month anniversary of the Effective Date, nor shall he or she cause or induce any corporation, partnership, limited liability company or other entity to: (i) solicit any Client for any purpose with respect to a Restricted Business or Solicit any Client to reduce or refrain from doing any business with the Company or its affiliates, (ii) transact business with any Client that would cause Director to be engaged in a Restricted Business with such Client in a Restricted Territory, (iii) interfere with or damage any relationship between the Company or its affiliates and a Client or (iv) Solicit anyone who is then an employee of the Company or its affiliates (or who was an employee of the Company or its affiliates within the prior 12 months) to resign from the Company or its affiliates or to apply for or accept employment with, or to act as an agent, consultant, independent contractor or partner in, any other business or enterprise. Nothing contained in this Agreement is intended to prohibit general advertising or solicitation not directed at any or all of the Clients or employees of the Company or any of its affiliates. For purposes of subsection (iv) of this Section 1(c), Director shall not be

-3-

prohibited from soliciting any former employees of the Company or its affiliates who have been terminated by the Company or one of its affiliates.

(d) Confidentiality. Director hereby acknowledges that, as a director of Columbia Trust and/or Columbia Trust Bank, he makes use of, acquires and adds to confidential information of a special and unique nature and value relating to Columbia Trust and Columbia Trust Bank and their respective strategic plans and financial operations (such information, the “Confidential Information”). Director further recognizes and acknowledges that all Confidential Information is the exclusive property of Columbia Trust or Columbia Trust Bank, as the case may be, is material and confidential, and is critical to the successful conduct of the business of Columbia Trust or Columbia Trust Bank, as the case may be. Accordingly, Director hereby covenants and agrees that he will use Confidential Information for the benefit of the Company only and shall not at any time, directly or indirectly, during the term of this Agreement and thereafter, divulge, reveal or communicate any Confidential Information to any person, firm, corporation or entity whatsoever, or use any Confidential Information for his own benefit or for the benefit of others.

(e) Separate Covenants. If, in any judicial proceeding, a court shall refuse to enforce any of the separate covenants (or any part thereof) contained in the preceding paragraphs of this Section 1, then such unenforceable covenants (or such part) shall be deemed eliminated from this Agreement for the purpose of those proceedings to the extent necessary to permit the remaining separate covenants (or portions thereof) to be enforced.

(f) Reformation. In the event that the provisions of this Section 1 should ever be deemed to exceed the duration or geographic limitations or scope permitted by applicable law, then such provisions shall be reformed to the maximum time or geographic limitations or scope, as the case may be, permitted by applicable laws.

(g) Specific Performance. Director acknowledges that it would be impossible to determine the amount of damages that would result from any breach of any of the provisions of this Section 1 and that the remedy at law for any breach, or threatened breach, of any of such provisions would likely be inadequate and, accordingly, agrees that AmericanWest shall, in addition to any other rights or remedies which it may have, be entitled to seek such equitable and injunctive relief as may be available from any court of competent jurisdiction to restrain Director from violating any of such provisions of this Agreement. In connection with any action or proceeding for injunctive relief, Director hereby waives the claim or defense that a remedy at law alone is adequate and agrees, to the maximum extent permitted by law, to have each such provision of this Section 1 specifically enforced against Director, without the necessity of posting bond or other security against Director, and consents to the entry of injunctive relief against Director enjoining or restraining any breach or threatened breach of such provisions of this Section 1.

-4-

(h) Survival. Any termination of Director’s employment or of this Agreement (or breach of this Agreement by Director or AmericanWest) shall have no effect on the continuing operation of this Section 1.

Miscellaneous.

(a) Amendment; Waiver. This Agreement may not be modified or amended except by a written instrument signed by authorized representatives of both parties and referring specifically to this Agreement. No waiver of any breach or default hereunder shall be considered valid unless in writing and signed by the party giving such waiver, and no such waiver shall be deemed a waiver of any subsequent breach of the same or similar nature.

(b) Counterparts. For the convenience of the parties hereto, this Agreement may be executed in any number of counterparts or facsimile counterparts, each such counterpart being deemed to be an original instrument, and all such counterparts shall together constitute one and the same agreement.

(c) Attorney’s Fees. The prevailing party or parties in any litigation, arbitration, mediation, bankruptcy, insolvency or other proceeding (“Proceeding”) relating to the enforcement or interpretation of this Agreement may recover from the unsuccessful party or parties all reasonable fees and disbursements of counsel (including expert witness and other consultants’ fees and costs) relating to or arising out of (a) the Proceeding (whether or not it proceeds to judgment) and (b) any post-judgment or post-award proceeding including, without limitation, one to enforce or collect any judgment or award resulting from the Proceeding. All such judgments and awards shall contain a specific provision for the recovery of all such subsequently incurred costs, expenses, and fees and disbursements of counsel.

(d) Governing Law. This Agreement shall be governed in all respects, including validity, interpretation and effect, by the laws of the State of Washington without regard to the conflicts of law principles thereof.

(e) Jurisdiction. Any legal action or proceeding with respect to this Agreement or the Merger Agreement may be brought in the courts of the State of Washington or of the United States of America for the Eastern District of Washington and, by execution and delivery of this Agreement, each of Director and AmericanWest hereby accepts for himself and itself and in respect of his or its property, generally and unconditionally, the jurisdiction of the aforesaid courts. Each of Director and AmericanWest irrevocably consents to the service of process out of any of the aforementioned courts in any such action or proceeding by the delivery of notice as provided in Section 2 (e) below, such service to become effective 30 days after such delivery.

-5-

(f) Notices. Any notice, request, instruction or other document to be given hereunder by any party to the others shall be in writing and delivered personally or sent by registered or certified mail, postage prepaid or next-day courier:

AmericanWest Bancorporation

41 West Riverside Avenue, Suite 400

Spokane, Washington 99201

Ladies and Gentlemen:

I have been advised that as of the date hereof I may be deemed to be an “affiliate” of Columbia Trust Bancorp, a Washington corporation (“the Company”), as the term “affiliate” is defined for purposes of paragraphs (c) and (d) of Rule 145 (“Rule 145”) of the Rules and Regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Act”). I have been further advised that pursuant to the terms of the Agreement and Plan of Merger, dated as of November 29, 2005 (the “Merger Agreement”), by and between AmericanWest Bancorporation (“AmericanWest”) and the Company, the Company will be merged into AmericanWest (the “Merger”), and that as a result of the Merger, I may be eligible to receive shares of common stock of AmericanWest (“AmericanWest”) in exchange for shares of Company Common Stock (as defined in the Merger Agreement) owned by me.

I hereby represent, warrant and covenant to AmericanWest that in the event I receive any AmericanWest Common Stock pursuant to the Merger:

1. I shall not make any sale, transfer or other disposition of the AmericanWest Common Stock in violation of the Act or the Rules and Regulations.

2. I have carefully read this letter and the Merger Agreement and discussed its requirements and other applicable limitations upon my ability to sell, transfer or otherwise dispose of AmericanWest Common Stock to the extent I believed necessary with my counsel or with counsel for the Company.

3. I have been advised that any issuance of AmericanWest Common Stock to me pursuant to the Merger Agreement has been registered with the SEC on a registration statement on Form S-4. However, I have also been advised that, since at the time the Merger will be submitted to the shareholders of the Company for approval I may be an “affiliate” of the Company, any sale or disposition by me of any of the AmericanWest Common Stock may only be made, under current law, in accordance with the provisions of paragraph (d) of Rule 145 under the Act, pursuant to an effective registration statement under the Act or pursuant to an exemption thereunder. I agree that I will not sell, transfer, or otherwise dispose of AmericanWest Common Stock issued to me in the Merger unless (i) such sale, transfer or other disposition has been registered under the Act; (ii) such sale, transfer or other disposition is made in conformity with the volume and other limitations of Rule 144 promulgated by the SEC under the Act; or (iii) in the written opinion of counsel, which opinion and counsel shall be reasonably acceptable to AmericanWest, such sale, transfer or other disposition is otherwise exempt from registration under the Act.

4. I understand that AmericanWest is under no obligation to register the sale, transfer or other disposition of the AmericanWest Common Stock by me or on my behalf or to take any other action necessary to make compliance with an exemption from registration available.

5. I understand that stop transfer instructions will be given to AmericanWest’s transfer agent with respect to AmericanWest Common Stock and that there will be placed on the certificates for the AmericanWest Common Stock issued to me, or any substitutions therefor, a legend stating in substance:

“The securities represented by this certificate have been issued in a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies and may be sold or otherwise transferred only in compliance with the requirements of Rule 145 or pursuant to a registration statement under said act or an exemption from such registration.”

6. I also understand that unless the transfer by me of my AmericanWest Common Stock has been registered under the Act or is a sale made in conformity with the provisions of Rule 145, AmericanWest reserves the right to put the following legend on the certificates issued to my transferee:

“The sale of the shares represented by this certificate has not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and the shares were acquired from a person who received such shares in a transaction to which Rule 145 promulgated under the Securities Act applies. The shares have been acquired by the holder not with a view to, or for resale in connection with, any distribution thereof within the meaning of the Securities Act and may not be sold, pledged or otherwise transferred except in accordance with an exemption from the registration requirements of the Securities Act.”

It is understood and agreed that this letter agreement shall terminate and be of no further force and effect and the legends set forth in paragraphs (5) or (6) above, as the case may be, shall be removed by delivery of substitute certificates without such legend, and the related stop transfer of restrictions shall be lifted forthwith, if (i) any such shares of AmericanWest Common Stock shall have been registered under the Act for sale, transfer or other disposition by me or on my behalf and are sold, transferred or otherwise disposed of, or (ii) any such shares of AmericanWest Common Stock are sold in accordance with the provisions of paragraphs (c), (e), (f) and (g) of Rule 144 promulgated under the Act, or (iii) I am not at the time an affiliate of AmericanWest and have been the beneficial owner of the AmericanWest Common Stock for at least one year (or such other period as may be prescribed by the Act and the Rules and Regulations, and AmericanWest has filed with the SEC all of the reports it is required to file under the Securities Exchange Act of 1934, as amended, during the preceding 12 months, or (iv) I am not and have not been for at least three months an affiliate of AmericanWest and have been the beneficial owner of the AmericanWest Common Stock for at least two years (or such other period as may be prescribed by the Act and the Rules and Regulations), or (v) AmericanWest

shall have received a letter from the Staff of the SEC, or a written opinion of counsel, which opinion and counsel shall be reasonably acceptable to AmericanWest, to the effect that the stock transfer restrictions and the legend are not required.


Sincerely,
