If any holder of a stock option of TCB Common Stock (a “TCB Option”) exercises such TCB Option after the Execution Date and before the Effective Date, the shares of TCB Common Stock issued upon such exercise will be converted into the right to receive the Per Share Consideration defined in Section 2.1.2.

2.2.2

Conversion on the Effective Date. On the Effective Date, by virtue of the Transaction, and without any action on the part of any holder of a TCB Option, each TCB Option that is then outstanding and unexercised will be converted into and become an option (a “Converted Option”) to purchase Columbia Common Stock on the same terms and conditions as are in effect with respect to the TCB Option immediately prior to the Effective Date, except that (A) each such Converted Option may be exercised solely for shares of Columbia Common Stock, (B) the number of shares of Columbia Common Stock subject to such Converted Option will be equal to the number of shares of TCB Common Stock subject to such TCB Option immediately prior to the Effective Date multiplied by the quotient, rounded to the nearest 10,000^th, obtained by dividing the value of the Per Share Consideration by the Columbia Average Closing Price (defined in Section 7.2.3), the product being rounded, if necessary, up or down to the nearest whole share, and (C) the per-share exercise price for each such Converted Option will be adjusted by dividing the per share exercise price of the TCB Option by the quotient, rounded to the nearest 10,000^th obtained by dividing the value of the Per Share Consideration by the Columbia Average Closing Price (defined in Section 7.2.3), and rounding up or down to the nearest cent.

2.2.3

Form S-8. Within thirty (30) days following the Effective Date, Columbia will prepare and file with the SEC a Registration Statement on Form S-8 or other appropriate form covering shares of Columbia Common Stock to be issued upon the exercise of the Converted Options.

2.2.4

Notice to Option Holders. Within fifteen (15) days following the Effective Date, Columbia will deliver to each holder of a Converted Option a written statement setting forth the number of shares of Columbia Common Stock that are subject to such holder’s Converted Option, the per-share exercise price of such Converted Option, and the date on which such Converted Option will terminate.

2.3

No Fractional Shares. Notwithstanding any other provision of this Agreement, no fractional shares of Columbia Common Stock will be issued. In lieu of fractional shares, if any, each holder of TCB Common Stock who is otherwise entitled to receive a fractional share of Columbia Common Stock will receive an amount of cash equal to the product of such fractional share multiplied by the Columbia Average Closing Price. Such fractional share interests will not include the right to vote or receive dividends or any interest on dividends.

2.4

Payment to Dissenting Stockholders. For purposes of this Agreement, “Perfected Dissenting Shares“ means those shares of TCB Common Stock as to which holders thereof have properly taken all steps necessary to exercise their dissenters’ rights under §§ 60.551 – 60.594 of the Oregon Revised Statutes (“Appraisal Laws“). Each outstanding Perfected Dissenting Share will be converted into the rights provided under the Appraisal Laws in accordance with the Appraisal Laws, unless the holder thereof withdraws his or her demand for payment, in which case each such share (a “Withdrawn Dissenting Share“) shall be deemed to have been converted on the Effective Date into the right to receive from Columbia the Per Share Consideration, without any interest. To the extent a holder of Proposed Dissenting Shares fails to perfect such holder’s dissenters’ rights under the Appraisal Laws, such Proposed Dissenting Shares shall be treated as

Withdrawn Dissenting Shares under this Agreement. Each holder of Perfected Dissenting Shares who becomes entitled to payment for his or her TCB Common Stock pursuant to the provisions of the Appraisal Laws shall receive payment for such Perfected Dissenting Shares from Columbia in accordance with the Appraisal Laws.

2.5

Deposit of Cash and Shares. On or before the Effective Date, Columbia will deposit, or will cause to be deposited, with the Exchange Agent, for the benefit of the holders of Certificates, for exchange in accordance with this Section 2.5, (i) certificates representing the Columbia Common Stock to be issued in exchange for outstanding shares of TCB Common Stock pursuant to Section 2.1.2; (ii) such cash as will be necessary to pay the Per Share Cash Consideration; and (iii) the cash in lieu of fractional shares to be paid in accordance with Section 2.3. Such cash and certificates for Columbia Shares, are referred to in this Agreement as the “Exchange Fund.”

2.6

Certificates.

2.6.1

Surrender of Certificates. Subject to Section 2.4, each Certificate (other than those evidencing Proposed Dissenting Shares) will, from and after the Effective Date, be deemed for all corporate purposes to represent and evidence only the right to receive the Per Share Consideration (including the cash for fractional shares, if any) to which the TCB Common Stock is converted in accordance with the provisions of this Section 2.6.1. Following the Effective Date, holders of Certificates will exchange their Certificates in accordance with instructions provided by the Exchange Agent together with a properly completed and executed form of transmittal letter in order to effect their exchange for (i) certificates representing Columbia Common Stock; (ii) a check representing the Per Share Cash Consideration; and (iii) a check representing the amount of cash in lieu of fractional shares, if any. Until a Certificate is so surrendered, the holder will not be entitled to receive any certificates evidencing Columbia Shares, the Per Share Cash Consideration, or cash in lieu of fractional shares.

2.6.2

Issuance of Certificates and Checks in Other Names. Any person requesting that any certificate evidencing Columbia Shares or any check in payment of the Per Share Cash Consideration (and cash in lieu of fractional shares, if any) be issued in a name other than the name in which the surrendered Certificate is registered, must: (1) establish to the Exchange Agent’s satisfaction the right to receive the Per Share Consideration and (2) either pay to the Exchange Agent any applicable transfer or other taxes or establish to the Exchange Agent’s satisfaction that all applicable taxes have been paid or are not required.

2.6.3

Lost, Stolen, and Destroyed Certificates. With respect to a Certificate that has been lost, stolen or destroyed, the Exchange Agent will be authorized to issue a certificate representing Columbia Shares in exchange thereof, pay the Per Share Cash Consideration and cash in lieu of any fractional share in exchange thereof, if the holder provides the Exchange Agent with: (1) satisfactory evidence that the holder owns TCB Common Stock and that the certificate representing this ownership is lost, stolen, or destroyed, (2) any appropriate affidavit the Exchange Agent may require, and (3) any reasonable assurances that the Exchange Agent or Columbia may require.

2.6.4

Rights to Dividends and Distributions. After the Effective Date, no holder of any Certificate will be entitled to receive any dividends or other distributions otherwise payable to holders of record of Columbia Common Stock on any date after the Effective Date, unless the holder (1) is entitled by this Agreement to receive a certificate

representing Columbia Common Stock and (2) has surrendered in accordance with this Agreement his or her Certificates (or has met the requirements of Section 2.6.3 above) in exchange for certificates representing Columbia Shares. Surrender of Certificates will not deprive the holder of any dividends or distributions that the holder is entitled to receive as a record holder of TCB Common Stock on a date before the Effective Date. When the holder surrenders his or her Certificates in exchange for Columbia Shares, the holder will receive the amount, without interest, of any cash dividends and any other distributions distributed after the Effective Date on the whole number of Columbia Shares into which the holder’s TCB Common Stock was converted at the Effective Date.

2.6.5

Affiliates. Certificates that are surrendered for exchange by any person constituting an “affiliate” of TCB for purposes of Rule 145 of the Securities Act will not be exchanged for certificates representing Columbia Shares until Columbia has received a written agreement from such person as specified in Section 4.3.1.

2.6.6

Undelivered Certificates. Any portion of the Exchange Fund that remains unclaimed by stockholders of TCB for 6 months after the Effective Date may be paid to Columbia. To the extent so paid, holders of TCB Common Stock who have not, prior to such time, complied with the provisions of this Section 2.6 will, from such time forward, look only to Columbia for payment of the Per Share Consideration, the cash in lieu of fractional shares, and/or unpaid dividends and distributions on the Columbia Shares deliverable with respect to each share of TCB Common Stock held by such holder as determined pursuant to this Agreement, in each case, without any interest. Neither Columbia nor TCB will be liable to any holder of TCB Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

2.7

Reservation of Right to Revise Transaction Structure. Notwithstanding any other provision in this Agreement to the contrary, Columbia may, with TCB’s consent (which will not be unreasonably withheld), at any time change the method of effecting its acquisition of TCB and the Bank; provided, however, that (A) no such change shall alter or change the amount, proportions or kind of consideration to be issued to holders of TCB Common Stock as provided for in this Agreement, (B) no such change shall adversely affect the tax treatment to holders of TCB Common Stock as a result of receiving such consideration, and (C) no delay caused by such a change shall be the basis upon which Columbia terminates this Agreement pursuant to Section 7.1. If the parties elect to change the method of acquisition, they will cooperate with and assist one another with any necessary amendment to this Agreement, and with the preparation and filing of such applications, documents, instruments and notices as may be necessary or desirable, in the opinion of counsel for Columbia, to obtain all necessary stockholder approvals and approvals of any regulatory agency, administrative body or other governmental entity.

6.3.3

6.4

Indemnification; D&O Insurance.

Indemnification Under Applicable Law and TCB’s and the Bank’s Articles/Bylaws. Columbia agrees that from and after the Effective Date, Columbia will indemnify and hold harmless each present and former director and officer of TCB and the Bank, determined as of the Effective Date (the “Indemnified Parties”), against any 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 or pertaining to matters existing or occurring at or prior to the Effective Date, whether asserted or claimed prior to, at or after the Effective Date, to the fullest extent that TCB and the Bank would have been permitted to indemnify such person under applicable federal and state law and the articles of incorporation or bylaws of TCB and the Bank in effect on the Execution Date (and Columbia will also advance expenses as incurred to the fullest extent permitted under applicable law; provided, that the person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification).

6.4.2

Indemnification by Columbia. To the extent that Section 6.4.1 will not serve to indemnify and hold harmless an Indemnified Party, Columbia agrees that it will, subject to the terms set forth herein, indemnify and hold harmless, to the fullest extent permitted under applicable law (and Columbia will also advance expenses as incurred to the fullest extent permitted under applicable law, provided, that the person to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification), each Indemnified Party against any Costs incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the transactions contemplated by this Agreement. All rights to indemnification in respect of any such claim or claims will continue until final disposition of any and all such claims.

6.4.3

Procedural Matters. Any Indemnified Party wishing to claim indemnification under Section 6.4.1 or 6.4.2, upon learning of any such claim, action, suit, proceeding or investigation, will promptly notify Columbia, but the failure to so notify will not relieve Columbia of any liability it may have to such Indemnified Party if such failure does not materially prejudice Columbia. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Date), Columbia will have the right to assume the defense thereof and Columbia will not be liable to such Indemnified

Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that, if Columbia elects not to assume such defense or counsel for the Indemnified Parties advises that there are issues which raise conflicts of interest between Columbia and the Indemnified Parties, the Indemnified Parties may retain counsel satisfactory to them, and Columbia will pay all reasonable fees and expenses of such counsel for the Indemnified Parties promptly as statements therefor are received. If such indemnity is not available with respect to any Indemnified Party, then Columbia and the Indemnified Party will contribute to the amount payable in such proportion as is appropriate to reflect relative faults and benefits.

6.4.4

Insurance. For a period of 3 years following the Effective Date, Columbia will cause the persons serving as officers and directors of TCB and the Bank immediately prior to the Execution Date to be covered by the current policies of directors and officers liability insurance maintained by TCB and the Bank with respect to acts or omissions of officers and directors, in their capacity as such, occurring on or prior to the Effective Date; provided, however, that Columbia may substitute comparable insurance policies of at least the same coverage and amounts and containing terms and conditions that are not substantially less advantageous than such policies.

6.4.5

Indemnification Agreements. Columbia will provide the former directors of TCB and/or the Bank who serve as advisory directors to CB after the Effective Date with contractual rights to indemnification comparable to the rights that directors of Columbia’s subsidiaries have under Columbia’s articles.

6.4.6

Effect of Provisions. The provisions of this Section 6.4 are intended to be for the benefit of, and shall be enforceable by, each of the Indemnified Parties and his or her heirs or representatives. Columbia shall make proper provision so any successors or assigns of Columbia or CB assume the obligations set forth in this Section 6.4.

7.2.1

Columbia’s Right to Adjust Consideration. If, on the Business Day immediately following the Determination Date, the Columbia Average Closing Price (defined below) is greater than $38.05, Columbia may elect by written notice to TCB to adjust the Per Share Stock Consideration through reducing the Per Share Consideration such that the Per Share Stock Consideration equals the number of shares of Columbia Common Stock that would have been issued had the Columbia Average Closing Price been $38.05. (If Columbia declares or effects a stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or similar transaction between the Execution Date and the Determination Date, the price for the Columbia Common Stock will be appropriately adjusted for the purpose of applying this Section 7.2.1).

7.3.1

Termination Due To Columbia Initial Closing Price Decrease. TCB may terminate this Agreement and the Merger by written notice to Columbia on the Business Day immediately following the Determination Date, in the event that:

(a)

The Columbia Average Closing Price is less than $29.59; and

(b)

The number obtained by dividing the Columbia Average Closing Price by $33.82 (the “Columbia Change Ratio”) is less than the number obtained by (i) dividing the Final Index Price by the Initial Index Price (both as defined below) (the “Index Change Ratio”) and then (ii) multiplying the quotient so obtained by 0.875.

The foregoing events in (a) and (b) are referred to as the “Adjustment Triggers.” If Columbia declares or effects a stock dividend, reclassification, recapitalization, split-up, combination, exchange of shares or similar transaction between the Execution Date and the Determination Date, the prices for the Columbia Common Stock shall be appropriately adjusted for the purposes of applying this Section 7.3. If TCB elects to exercise its termination right as a result of the Adjustment Triggers, the provisions of Section 7.3.3 will apply.

“Index Group“ means the 12 financial institutions listed on Exhibit D attached hereto, the common stock of all of which shall be publicly traded and as to which there shall not have been a publicly announced proposal at any time during the period beginning on the Execution Date and ending on the Determination Date. In the event that the common stock of any such company ceases to be publicly traded or a proposal to acquire any such company is announced at any time during the period beginning on the Execution Date and ending on the Determination Date, such company will be removed from the Index Group, and the weights attributed to the remaining companies will be adjusted proportionately for purposes of determining the Final Index Price and the Initial Index Price. The 12 financial institutions and the weights attributed to them are listed on Exhibit D.

“Initial Index Price“ means $28.59, which is the sum of each per share closing price of the common stock of each company comprising the Index Group multiplied by the applicable weighting, as such prices are reported on the consolidated transactions reporting system for the market or exchange on which such common stock is principally traded, on March 23, 2007, which amount may be adjusted as described in above in the definition of “Index Group.”

“Per Share Consideration Increase” means the product of:

Notwithstanding the foregoing, any such increase to the Per Share Consideration by Columbia shall not result in the adjusted Per Share Cash Consideration constituting more than 55% of the value of the sum of (i) the Adjusted Per Share Consideration and (ii) the amount to be paid for Proposed Dissenting Shares. If Columbia makes such election to increase the Per Share Consideration pursuant to Section 7.3.3, no termination will occur pursuant to this Section 7.3 and this Agreement will remain in effect according to its terms (except as the Per Share Consideration has been supplemented). If Columbia does not elect to increase the Per Share Consideration pursuant to Section 7.3.3, TCB may elect to terminate this Agreement by providing notice to Columbia four Business Days after providing its prior notice pursuant to Section 7.3.1.

A single arbitrator agreed on by the parties will conduct the arbitration. If the parties cannot agree on a single arbitrator, each party must select one arbitrator and those two arbitrators will select a third arbitrator. This third arbitrator will hear the dispute. The arbitrator’s decision is final (except as otherwise specifically provided by law) and binds the parties, and either party may request any court having jurisdiction to enter a judgment and to enforce the arbitrator’s decision. The arbitrator will provide the parties with a written decision naming the prevailing party in the action. This prevailing party is entitled to reimbursement from the other party for its costs and expenses, including reasonable attorneys’ fees.

8.9

No Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned by any of the parties (whether by operation of law or otherwise) without the prior written consent of the other parties. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns. Except as otherwise expressly provided, this Agreement (including the documents and instruments referred to in this Agreement) is not intended to confer upon any person other than the parties any rights or remedies under this Agreement.
