Any WBC Common Stock with respect to which the Exchange Agent has not received an effective, properly completed Election Form on or before 5:00 p.m., Pacific Time, on the date prior to the Determination Date (or such other time and date as Frontier and WBC may mutually agree) (the “Election Deadline”) shall also be deemed to be “No Election Shares.” The term “Cash Percentage” shall mean the quotient, rounded to the nearest thousandth, obtained by dividing (x) the quotient obtained by dividing the Total Cash Amount by the Per Share Consideration, by (y) the total number of shares of WBC Common Stock outstanding as of the close of business on the Determination Date. “Stock Percentage” shall mean the amount equal to one (1) minus the Cash Percentage.

(C) Frontier shall make available one or more Election Forms as may reasonably be requested from time to time by all persons who become holders (or beneficial owners) of WBC Common Stock between the Election Form Record Date and the close of business on the business day prior to the Election Deadline, and WBC shall provide to the Exchange Agent all information reasonably necessary for it to perform as specified herein.

(D) Any such election shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline. An Election Form shall be deemed properly completed only 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 WBC Common Stock covered by such Election Form, together with duly executed transmittal materials included in the Election Form. Any Election Form may be revoked or changed by the person submitting such Election Form at or prior to the Election Deadline. In the event an Election Form is revoked prior to the Election Deadline, the shares of WBC Common Stock represented by such Election Form shall become No Election Shares and Frontier shall cause the certificates representing WBC Common Stock to be promptly returned without charge to the Person submitting the Election Form upon written request to that effect from the holder who submitted the 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 good faith decisions of Frontier regarding such matters shall be binding and conclusive.

(E) Within ten (10) business days after the Election Deadline, unless the Effective Time has not yet occurred, in which case as soon thereafter as practicable, Frontier shall cause the Exchange Agent to effect the allocation among the holders of WBC Common Stock of rights to receive Frontier Common Stock or cash in the Merger as follows:

(1) Cash Election Shares Plus Mixed Cash Shares More Than Total Cash Amount. If the aggregate cash amount that would be paid upon the conversion in the Merger for the Cash Election Shares and the Mixed Cash Shares is greater than the Total Cash Amount, then:




AGREEMENT AND PLAN OF MERGER		10

(i) all Stock Election Shares, Mixed Stock Shares and No Election Shares shall be converted into the right to receive the Per Share Stock Consideration;

(ii) the Exchange Agent shall then select first from among the Cash Election Shares and then (if necessary) from the Mixed Cash Election Shares, by a pro rata selection process, a sufficient number of shares (“Stock Designated Shares”) such that the aggregate cash amount that will be paid in the Merger equals as closely as practicable, but in no event less than, the Total Cash Amount, and all Stock Designated Shares shall be converted into the right to receive the Per Share Stock Consideration; and

(iii) the Cash Election Shares and Mixed Cash Shares that are not Stock Designated Shares will be converted into the right to receive the Per Share Cash Consideration.

(2) Cash Election Shares Plus Mixed Cash Shares Less Than Total Cash Amount. If the aggregate cash amount that would be paid upon the conversion in the Merger for the Cash Election Shares and the Mixed Cash Shares is less than the Total Cash Amount, then:

(i) all Cash Election Shares and Mixed Cash Shares shall be converted into the right to receive the Per Share Cash Consideration;

(ii) the Exchange Agent shall then select first from among the No Election Shares and second (if necessary) from among the Stock Election Shares and finally (if necessary) from the Mixed Stock Election Shares, by a pro rata selection process, a sufficient number of shares (“Cash Designated Shares”) such that the aggregate cash amount that will be paid in the Merger equals as closely as practicable the Total Cash Amount, and all Cash Designated Shares shall be converted into the right to receive the Per Share Cash Consideration; and

(iii) the Stock Election Shares, No Election Shares and Mixed Stock Shares that are not Cash Designated Shares shall be converted into the right to receive the Per Share Stock Consideration.

(3) Cash Election Shares Plus Mixed Cash Shares Equal to Total Cash Amount. If the aggregate cash amount that would be paid upon conversion in the Merger for the Cash Election Shares and the Mixed Cash Shares is equal or nearly equal (as determined by the Exchange Agent) to the Total Cash Amount, then subparagraphs (1) and (2) above shall not apply, and all Cash Election Shares and Mixed Cash Shares shall be converted into the right to receive the Per Share Cash Consideration, and all Stock Election Shares, Mixed Stock Shares, and No Election Shares shall be converted into the right to receive the Per Share Stock Consideration.

(F) The pro rata selection process to be used by the Exchange Agent shall consist of such equitable pro ration processes as shall be determined by Frontier and reasonably satisfactory to WBC.

1.5 WBC OPTIONS. Notwithstanding anything to the contrary in this Agreement, and in addition to the Aggregate Consideration:

(A) Unexercised Options.




AGREEMENT AND PLAN OF MERGER		11

(1) At the Effective Time, each WBC Option that is unexercised by the Effective Time shall be converted into a fully vested option to acquire a number of shares of Frontier Common Stock equal to the product (rounded down to the nearest whole number) of (x) the number of shares of WBC Common Stock subject to the WBC 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 share of WBC Common Stock of such WBC 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 Frontier Common Stock purchasable pursuant to the WBC 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 WBC Option to which Section 422 of the Code applies, the exercise price and the number of shares of Frontier Common 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 WBC Option shall continue to be governed by the same terms and conditions as were applicable under such WBC 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 Per Share Consideration and having a denominator equal to the Frontier Average Share Price.

(2) As soon as practicable after the Effective Time, Frontier will prepare and file with the SEC a Registration Statement on Form S-8 covering shares of Frontier Common Stock to be issued upon the exercise of stock options assumed by Frontier pursuant to this Section 1.5(A).

(3) At or prior to the Effective Time, WBC, the WBC Board and the compensation committee of the WBC Board, as applicable, shall adopt any resolutions and take any actions which are necessary to effectuate the provisions of this Section 1.5(A). WBC shall take all actions necessary to ensure that, from and after the Effective Time, Frontier will not be required to deliver WBC Common Stock or other capital stock of WBC to any Person pursuant to or in settlement of WBC Options.

(B) The names of the holders, dates of issuance and expiration, the number of shares subject to each such option, and the exercise price for all WBC Options as of the Execution Date are set forth in Schedule 1.5(B). All such WBC Options shall be 100% vested and exercisable at the Effective Time pursuant to the 2005 Stock Incentive Plan, the 1998 Stock Option and Restricted Stock Award Plan, the 1993 Director Stock Option Plan and the 1992 Stock Option Plan (collectively, the “WBC Stock Option Plans”).

1.6 DISSENTING SHARES. Notwithstanding anything to the contrary in this Agreement, each Dissenting Share whose holder, as of the Effective Time of the Merger, has not effectively withdrawn or lost his or her dissenters’ rights under Ch. 23B.13 RCW (the “Appraisal Laws”) shall not be converted into or represent a right to receive the Per Share Cash Consideration or Frontier Common Stock, but the holder of such Dissenting Share shall be entitled only to such rights as are granted by the Appraisal Laws, unless and until such holder shall have failed to perfect or shall have effectively withdrawn or lost the right to payment under the Appraisal Laws, in which case each such share shall be deemed to have been converted at the Effective Time into the right to receive cash and/or Frontier Common Stock (based on the Per Share Stock Consideration defined in Section 1.3(A)) without any interest thereon, in the same proportions determined under Section 1.5(A) with respect to WBC Options that are unexercised by the Effective Time. Each holder of Dissenting Shares who becomes entitled to




AGREEMENT AND PLAN OF MERGER		12

payment for his WBC Common Stock pursuant to the provisions of the Appraisal Laws shall receive payment for such Dissenting Shares from Frontier (but only after the amount thereof shall have been agreed upon or finally determined pursuant to the Appraisal Laws).

1.7 TAX CONSEQUENCES. It is intended that the Merger shall constitute a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”) and that this Agreement shall constitute a plan of reorganization for the purposes of Section 368 of the Code.

ARTICLE II. EXCHANGE OF SHARES

2.1 FRONTIER TO MAKE SHARES AND CASH AVAILABLE. On or before the Effective Time, Frontier shall deposit, or shall cause to be deposited, with American Stock Transfer & Trust Company (the “Exchange Agent”), for the benefit of the holders of WBC Common Stock as of the Effective Time, for exchange in accordance with this ARTICLE II: (A) certificates or electronic indicia of ownership representing the shares of Frontier Common Stock to be issued pursuant to Section 1.3 and Section 2.2(A) in exchange for outstanding shares of WBC Common Stock; (B) cash in the amount of the Total Cash Consideration; and (C) the cash in lieu of fractional shares to be paid in accordance with Section 2.2(E). Such cash and shares of Frontier Common Stock, together with any dividends or distributions with respect to such Frontier Common Stock, are hereinafter referred to as the “Exchange Fund.”

2.2 EXCHANGE OF SHARES.

(A) As soon as practicable after the Effective Time, and in no event more than five (5) business days thereafter, the Exchange Agent shall mail to each holder of record of a Certificate or Certificates who theretofore has not submitted such holder’s Certificate or Certificates with an Election Form, a form letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates or customary affidavits and indemnification regarding the loss or destruction of such certificates or the guaranteed delivery of such certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. After completion of the allocation procedure set forth in Section 1.4 and upon surrender of a Certificate or Certificates for exchange and cancellation to the Exchange Agent, together with a properly executed letter of transmittal or Election Form, as the case may be, the holder of such Certificate or Certificates shall be entitled to receive in exchange therefor (x) a certificate representing that number of whole shares of Frontier Common Stock which such holder of WBC Common Stock became entitled to receive pursuant to the provisions of ARTICLE I hereof and/or (y) a check representing the aggregate Per Share Cash Consideration and/or the amount of cash in lieu of fractional shares, if any, which such holder has the right to receive in respect of the Certificate or Certificates surrendered pursuant to the provisions of ARTICLE I, and the Certificate or Certificates so surrendered shall forthwith be canceled. No interest will be paid or accrued on the Per Share Cash Consideration, the cash in lieu of fractional shares or the unpaid dividends and distributions, if any, payable to holders of Certificates.

(B) No dividends or other distributions declared after the Effective Time with respect to Frontier Common Stock and payable to the holders of record thereof shall be paid to the holder of any unsurrendered Certificate until the holder thereof shall surrender such Certificate in accordance with this ARTICLE II. After the surrender of a Certificate in accordance with this ARTICLE II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any




AGREEMENT AND PLAN OF MERGER		13

interest thereon, which theretofore has become payable with respect to shares of Frontier Common Stock represented by such Certificate.

(C) If any certificate representing shares of Frontier Common Stock is to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of the issuance thereof that the Certificate so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other taxes required by reason of the issuance of a certificate representing shares of Frontier Common Stock in any name other than that of the registered holder of the Certificate surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

(D) After the Effective Time, there shall be no transfers on the stock transfer books of WBC of the shares of WBC Common Stock which were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be canceled and exchanged for certificates representing shares of Frontier Common Stock or cash or both, as provided in this ARTICLE II.

(E) Notwithstanding anything to the contrary contained herein, no certificates or scrip representing fractional shares of Frontier Common Stock shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to Frontier Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Frontier. In lieu of the issuance of any such fractional share, Frontier shall pay to each former shareholder of WBC who otherwise would be entitled to receive a fractional share of Frontier Common Stock an amount in cash determined by multiplying (1) the Frontier Average Share Price by (2) the fraction of a share of Frontier Common Stock which such holder would otherwise be entitled to receive pursuant to Section 1.3 hereof.

(F) Frontier (through the Exchange Agent, if applicable) shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any holder of shares of WBC Common Stock such amounts as Frontier is required under the Code or any state, local or foreign tax law or regulation thereunder to deduct and withhold with respect to the making of such payment. Any amounts so withheld shall be treated for all purposes of this Agreement as having been paid to the holder of WBC Common Stock in respect of which such deduction and withholding was made by Frontier.

(G) Any portion of the Exchange Fund that remains unclaimed by the shareholders of WBC for twelve (12) months after the Effective Time shall be paid to Frontier. Any shareholders of WBC who have not theretofore complied with this ARTICLE II shall thereafter look only to Frontier for payment of the Merger Consideration, the cash in lieu of fractional shares and/or the unpaid dividends and distributions on the Frontier Common Stock deliverable in respect of each share of WBC Common Stock such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of Frontier, Frontier Bank, WBC, Whidbey Island Bank, the Exchange Agent or any other person shall be liable to any former holder of shares of WBC Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(H) In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Frontier, the posting by such person of a bond in such reasonable amount as Frontier




AGREEMENT AND PLAN OF MERGER		14

may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration deliverable in respect thereof pursuant to this Agreement.

ARTICLE VIII. TERMINATION AND AMENDMENT

8.1 TERMINATION. This Agreement may be terminated at any time prior to the Effective Time, before or after approval of the matters presented in connection with the Merger by the holders of WBC Common Stock, under each of the following conditions:

(A) MUTUAL CONSENT. By the mutual consent of Frontier and WBC, if the Board of Directors of each so determines by vote of a majority of the members of its entire board.

(B) DELAY. By Frontier or WBC in the event the Merger is not consummated by June 30, 2008, unless the failure of the consummation of the transactions to occur shall be due to the failure of the party seeking to terminate this Agreement to perform its obligations hereunder in a timely manner; provided, however, that a party may not terminate the Agreement pursuant to this Section 8.1(B) if it is in material breach of any of the provisions of the Agreement; provided, further, that Frontier may not terminate this Agreement pursuant to this Section 8.1(B), if such delay results from amendments to the Registration Statement or a resolicitation of proxies as a consequence of a Frontier Transaction, or any other acquisition or sale transaction, or any offering of securities, in which Frontier is involved.

(C) NO REGULATORY APPROVALS. By Frontier or WBC, in the event that any of the required regulatory approvals set forth in Section 7.1(B) are denied (or should any such required approval be conditioned upon a material deviation from the transactions contemplated); provided however, that either party may extend the term of this Agreement for a sixty (60) day period to prosecute diligently and overturn such denial provided that such denial has been appealed within fourteen (14) business days of the receipt thereof.

(D) BREACH OF WARRANTY. By Frontier or WBC (provided that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein) if there shall have been a material breach of any of the representations or warranties set forth in this Agreement on the part of the other party, which breach is not cured within thirty days following written notice to the party committing such breach, or which breach, by its nature, cannot be cured prior to the Effective Time; provided, however, that neither party shall have the right to terminate this Agreement pursuant to this Section 8.1(D) unless the breach of representation or warranty, together with all other such breaches, would entitle the party receiving such representation not to consummate the transactions contemplated hereby under Section 7.2(B) (in the case of a breach of representation or


AGREEMENT AND PLAN OF MERGER			41

warranty by WBC or Whidbey Island Bank) or Section 7.3(B) (in the case of a breach of representation or warranty by Frontier or Frontier Bank).

(E) BREACH OF COVENANT. By either Frontier or WBC (provided that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein) if there shall have been a material breach of any of the covenants or agreements set forth in this Agreement on the part of the other party, which breach shall not have been cured within thirty days following receipt by the breaching party of written notice of such breach from the other party hereto, or which breach, by its nature, cannot be cured prior to the Effective Time.

(F) SUPERIOR PROPOSAL. By WBC, in the event that the Board of Directors of WBC determines in good faith, after consultation with its financial adviser and outside counsel, that in light of a Superior Proposal (as defined in Section 9.3) it would not be consistent with its fiduciary duties to WBC and to WBC ‘s shareholders under applicable law to continue with the transactions contemplated under this Agreement; provided, however, that the Board of Directors of WBC may terminate this Agreement pursuant to this Section 8.1(F) solely in order to concurrently enter into a letter of intent, agreement in principle, acquisition agreement or other similar agreement (each, an “Acquisition Agreement”) related to a Superior Proposal; provided further, however, that this Agreement may be terminated pursuant to this Section 8.1(F) only after the fifth day following Frontier’s receipt of written notice advising Frontier that the Board of Directors of WBC is prepared to accept a Superior Proposal, and only if, during such five-day period, if Frontier so elects, WBC and its advisors shall have negotiated in good faith with Frontier to make such adjustments in the terms and conditions of this Agreement as would enable Frontier to proceed with the transactions contemplated herein on such adjusted terms.

(G) WALK-AWAY. By WBC upon its written notice to Frontier promptly before, but in no event later than five (5) Business Days prior to, the commencement of the Meeting, in the event that the Frontier Average Share Price is less than $21.00 at any time during the Measurement Period; provided, however, that this Agreement may be terminated by WBC pursuant to this Section 8.1(G) only if, after receipt of written notice advising Frontier that the Board of Directors of WBC is prepared to terminate this Agreement, Frontier does not, at least one day prior to the Meeting, agree to increase the Total Stock Amount and/or the Total Cash Amount if and to the extent necessary based on the Frontier Average Share Price as of the Effective Time, and consummate the Corporate Merger in a manner that would yield Aggregate Merger Consideration, on a per-share basis using the Frontier Average Share Price measured as of the Effective Time, of not less than $19.41. For purposes of this Section 8.1(G), the “Measurement Period” means that ten (10) Business Day period ending on the sixth Business Day prior to the date on which the Meeting is scheduled to occur. If either party 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 Frontier Common Stock shall be appropriately adjusted for purposes of applying this Section 8.1(G).

(H) SHAREHOLDER APPROVAL. By either Frontier or WBC if the approval of the shareholders of WBC required for the consummation of the Corporate Merger shall not have been obtained by reason of the failure to obtain the required vote at a duly held meeting of such shareholders or at any adjournment or postponement thereof.

(I) FRONTIER CONDITIONS PRECEDENT. By Frontier as a result of (1) a Material Adverse Change in WBC as set forth in Section 7.2(E), or (2) the Dissenting Shares exceed 10% of the WBC Common Stock.


AGREEMENT AND PLAN OF MERGER			42

(J) WBC CONDITIONS PRECEDENT. By WBC as a result of a Material Adverse Change in Frontier as set forth in Section 7.3(E), or if the condition set forth in Section 7.3(F) cannot be satisfied.

(K) NO FAIRNESS OPINION. By WBC in the event the fairness opinion described in Section 7.3(G) is not confirmed at the time referenced in such Section.

8.2 EFFECT OF TERMINATION.

(A) In the event of termination of this Agreement by either Frontier or WBC as provided in Section 8.1, this Agreement shall forthwith become void and have no effect except (1) Sections 6.5(D), 8.1(F), 8.2 and 9.3 shall survive any termination of this Agreement, and (2) that, notwithstanding anything to the contrary contained in this Agreement, no party shall be relieved or released from any liabilities or damages arising out of its willful breach of any provision of this Agreement.

(B) If WBC terminates this Agreement pursuant to Section 8.1(F), WBC shall pay to Frontier a termination fee equal to $7,500,000 (the “Termination Fee Amount”) by wire transfer of same day funds on the date of termination. The Termination Fee Amount shall also be payable by WBC under the circumstances set forth in Section 8.2(C).

(C) In the event that an Acquisition Proposal with respect to WBC shall have been made known to WBC and shall have been publicly announced or otherwise become public, or shall have been made to the shareholders of WBC, and thereafter (1) this Agreement is terminated by either Frontier or WBC pursuant to either (i) Section 8.1(B) hereof and prior to such termination the shareholders of WBC shall not have previously approved the Merger, or (ii) Section 8.1(H) hereof as a result of the failure of the shareholders of WBC to approve the Merger and (2) within twenty-four (24) months of such termination WBC enters into any Acquisition Agreement providing for any transaction described in clause (1) or clause (2) of Section 9.3(D), then upon the first occurrence of an event contemplated by this clause (2) WBC shall pay Frontier the Termination Fee Amount.

(D) If WBC terminates this Agreement pursuant to Section 8.1(D) or Section 8.1(E), Frontier shall pay to WBC a termination fee equal to $5,000,000 by wire transfer of same day funds on the date of termination.

(E) If Frontier terminates this Agreement pursuant to Section 8.1(D) or Section 8.1(E), WBC shall pay to Frontier a termination fee equal to $5,000,000 by wire transfer of same day funds on the date of the termination.

(F) The parties agree that the agreements contained in Sections 8.2(B), 8.2(C), 8.2(D) and 8.2(E) above are integral parts of the transactions contemplated by this Agreement and constitute liquidated damages and not a penalty.

(G) The Termination Fee Amount is intended to be triggered, if at all, no more than one (1) time, irrespective of any subsequent actions by WBC or any Third Party. The Termination Fee Amount is intended as an alternative to, and shall not be in addition to, the amount payable, if at all, under Section 8.2(E).


AGREEMENT AND PLAN OF MERGER			43

8.3 AMENDMENT. Subject to compliance with applicable law, this Agreement may be amended by the parties hereto, by action taken or authorized by their respective Boards of Directors, at any date before or after approval of the matters presented in connection with the Merger by the shareholders of WBC; provided, however, that after any approval of the transactions contemplated by this Agreement by WBC ‘s shareholders, there may not be, without further approval of such shareholders, any amendment of this Agreement which reduces the amount or changes the form of the consideration to be delivered to WBC shareholders hereunder other than as contemplated by this Agreement. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

8.4 EXTENSION; WAIVER. At any time prior to the Effective Time, by action taken or authorized by its Board of Directors, WBC or Frontier may, to the extent legally allowed, (A) extend the time for the performance of any of the obligations or other acts of the other party or its Subsidiaries hereto, (B) waive any inaccuracies in the representations and warranties of the other party or its Subsidiaries contained herein or in any document delivered pursuant hereto, and (C) waive compliance with any of the agreements or conditions of the other party contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party or its Subsidiaries, but such extension or waiver or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

ARTICLE IX. ADDITIONAL AGREEMENTS

9.1 ADDITIONAL AGREEMENTS. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation or Resulting Bank with full title to all properties, assets, rights, approvals, immunities and franchise of any of the parties to the Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by the other party.

9.2 BENEFIT PLANS.

(A) Upon consummation of the Merger, except as provided in the Employment Agreements, entered into with certain officers of WBC and Whidbey Island Bank, all employees of WBC and its Subsidiaries shall be deemed to be at-will employees of Frontier and its Subsidiaries. From and after the Effective Time, employees of WBC and its Subsidiaries shall be entitled to participate in the pension, employee benefit and similar plans (including stock option, bonus or other incentive plans) on substantially the same terms and conditions as similarly situated employees of Frontier and its Subsidiaries. For the purpose of determining eligibility to participate in such plans and the vesting and related calculations of benefits under such plans (but not for the vesting under Frontier’s 2006 Stock Incentive Plan or accrual of benefits under any such plan), Frontier shall give effect to years of service with WBC and its Subsidiaries as if such service were with Frontier and its Subsidiaries.

(B) As of or prior to the Effective Time, WBC shall adopt the relevant resolutions of its Board of Directors necessary to terminate the WBC 401(k) Plan (the “WBC 401(k) Plan”). In connection with such termination, the WBC 401(k) Plan shall be submitted to the Internal Revenue Service for a determination regarding its qualification upon termination and, upon receipt of a favorable determination letter, distributions shall be made to participants in accordance with ERISA, the Code, and the WBC 401(k) Plan as soon as practicable after the receipt of the determination letter. Neither Frontier, nor Frontier Bank, shall have any obligation to make contributions to the WBC 401(k) Plan after the


AGREEMENT AND PLAN OF MERGER			44

Effective Time. Participants in the WBC 401(k) Plan who become employees of Frontier or its Subsidiaries will be permitted, subject to the terms of the WBC 401(k) Plan, to rollover such distributions to Frontier’s 401(k) Plan.

(C) As of or prior to the Effective Time, WBC shall terminate and, if applicable, distribute all benefits under the Annual Incentive Compensation Plan, Commercial Loan Officer Annual Incentive and Executive Deferred Compensation Plan, and all related agreements. WBC will file any required IRS/DOL notices and reports with respect to the termination and distribution of such plans.

9.3 CERTAIN ACTIONS.

(A) Except with respect to this Agreement and the transactions contemplated hereby, neither WBC, Whidbey Island Bank nor any of their directors, officers, agents, affiliates (as such term is used in Rule 12b-2 under the Exchange Act) or representatives (collectively, “Representatives”) shall, directly or indirectly, initiate, solicit, encourage or facilitate (including by way of furnishing information) any inquiries with respect to or the making of any Acquisition Proposal (as defined below).

(B) Notwithstanding anything herein to the contrary, WBC and its Board of Directors shall be permitted (i) to comply with Rule 14d-9 and Rule 14e-2 promulgated under the Exchange Act with regard to an Acquisition Proposal, (ii) to engage in any discussions or negotiations with, or provide any information to, any person in response to an unsolicited bona fide written Acquisition Proposal by any such person, if and only to the extent that (a) WBC’s Board of Directors concludes in good faith and consistent with its fiduciary duties to WBC’s shareholders under applicable law that such Acquisition Proposal may result in a Superior Proposal (as defined below), (b) prior to providing any information or data to any person in connection with an Acquisition Proposal by any such person, WBC’s Board of Directors receives from such person an executed confidentiality agreement containing terms at least as stringent as those contained in the Confidentiality Agreement, and (c) prior to providing any information or data to any person or entering into discussions or negotiations with any person, WBC’s Board of Directors notifies Frontier promptly of such inquiries, proposals, or offers received by, any such information requested from, or any such discussions or negotiations sought to be initiated or continued with, any of its Representatives.

(C) WBC and Whidbey Island Bank each agrees that it will, and will cause its Representatives to, immediately cease and cause to be terminated any activities, discussions, or negotiations existing as of the Execution Date with any parties conducted heretofore with respect to any Acquisition Proposal, and shall use reasonable best efforts to cause all persons other than Frontier who have been furnished confidential information regarding WBC or Whidbey Island Bank in connection with the solicitation of or discussions regarding an Acquisition Proposal within the 12 months prior to the date hereof promptly to return or destroy such information. WBC and Whidbey Island Bank agree not to release any third party from the confidentiality and standstill provisions of any agreement to which WBC or Whidbey Island Bank is or may become a party, and shall immediately take all steps necessary to terminate any approval that may have been heretofore given under any such provisions authorizing any person to make an Acquisition Proposal.

(D) For purposes of this Section 9.3:

(1) The term “Acquisition Proposal” means any tender offer or exchange offer or any proposal for a merger, reorganization, consolidation, share exchange, recapitalization, liquidation, dissolution or other business combination involving WBC or Whidbey Island Bank or any proposal or offer to acquire a substantial equity interest in (other


AGREEMENT AND PLAN OF MERGER			45

than as part of a public offering to raise capital that does not require shareholder approval), or (other than in the ordinary course of business) a substantial portion of the assets of, WBC or Whidbey Island Bank, other than the transaction contemplated or permitted by this Agreement.

(2) The term “Superior Proposal” means, with respect to WBC or Whidbey Island Bank, any written Acquisition Proposal made by a person other than Frontier which is for (i) (a) a merger, reorganization, consolidation, share exchange, business combination, recapitalization or similar transaction involving WBC or Whidbey Island Bank, (b) a sale, lease, exchange, transfer, or other disposition of at least 25% of the assets of WBC or Whidbey Island Bank, taken as a whole, in a single transaction or a series of related transactions, or (c) the acquisition, directly or indirectly, by a person of beneficial ownership of 25% or more of the WBC Common Stock or Whidbey Island Bank Common Stock whether by merger, consolidation, share exchange, business combination, tender, or exchange offer or otherwise, and (ii) which is otherwise on terms which the Board of Directors of WBC in good faith concludes (after consultation with its financial advisors and outside counsel), taking into account, among other things, all legal, financial, regulatory, and other aspects of the proposal and the person making the proposal, (a) would, if consummated, result in a transaction that is more favorable to its shareholders (in their capacities as shareholders), from a financial point of view, than the transactions contemplated by this Agreement, and (b) is reasonably capable of being completed.

9.4 EMPLOYMENT AND CHANGE OF CONTROL AGREEMENTS. As of the Effective Time, Frontier shall assume and honor and shall cause Frontier Bank to assume and to honor in accordance with their terms the change of control provisions of WBC’s and Whidbey Island Bank’s employment and severance agreements with ▇▇▇▇▇▇ ▇. ▇▇▇▇, ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, ▇▇▇▇ ▇. ▇▇▇▇▇▇, ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇, ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and ▇▇▇▇ ▇▇▇▇▇, as described in Schedule 9.4 and as may be amended as of the Closing by the Noncompetition/Nonsolicitation Agreement, (collectively, the “Employment Agreements”). Frontier acknowledges and agrees that the Merger will constitute a merger, sale or a change in control of WBC and Whidbey Island Bank for all purposes under such Employment Agreements.

9.5 DIRECTORS OF WBC. After the Effective Time, one current director of WBC (as determined by Frontier) shall be appointed to the Frontier board of directors until the next shareholders’ meeting, at which time such appointee will, subject to the Frontier board’s fiduciary obligations, stand for election for a two-year term expiring in 2010. The composition of Frontier’s board of directors will be increased by one and will not be decreased in a manner that would limit Frontier’s ability to accommodate the WBC representative so designated. Compensation for such director (including compensation for committee assignments and like duties) will be consistent with Frontier’s compensation practices for other similarly situated directors of Frontier.

9.6 WBC MANAGEMENT. After the Effective Time, WBC’s chief executive officer will serve as the regional manager of the division of Frontier that serves such branches of WBC and Frontier as will be determined by Frontier’s chief executive officer, most of which are expected to be in the current WBC market. The regional manager will execute a Noncompetition/Nonsolicitation Agreement with Frontier that will continue until the later of the termination of the regional manager’s employment with Frontier or the second anniversary of the Effective Time. The salary, reporting and remaining terms of his employment will be mutually agreed upon by the parties; however, there will be no employment contract and the regional manager will be an at-will employee and serve at the pleasure of Frontier’s senior officers and board of directors.


AGREEMENT AND PLAN OF MERGER			46

9.7 AT-WILL EMPLOYEES. After the Effective Time, a substantial majority of the employees of WBC will have the opportunity to continue their at-will employment with Frontier, if and to the extent that mutually suitable job opportunities are available. WBC employees whose positions are eliminated as a result of the Merger, and who remain employees of WBC through Closing or, where required by Frontier for post-merger systems integration and conversion activities (“conversion”), through conversion, will be eligible to receive upon Closing or conversion severance pay and/or stay bonuses. The specific terms and conditions and personnel of the stay bonus/severance program will be determined by Frontier prior to closing, in consultation with WBC’s senior management.

ARTICLE X. GENERAL PROVISIONS

10.1 CLOSING; EFFECTIVE TIME. Subject to the terms and conditions of this Agreement, the closing of the Merger (the “Closing”) will take place at 10:00 a.m. on the first day which is at least one business day after the satisfaction or waiver (subject to applicable law) of the latest to occur of the conditions set forth in ARTICLE VII (other than those conditions which relate to actions to be taken at the Closing) (the “Effective Time”), at the offices of ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ L.L.P., unless another time, date or place is agreed to in writing by the parties hereto.

For purposes of this Agreement, the term “Intellectual Property” means any material trademarks, service marks, brand names, certification marks, trade dress or other indications of origin, the goodwill associated with the foregoing and applications in any jurisdiction to register, the foregoing, including any extension, modification or renewal of any such registration or application; patents, applications for patents (including divisions, continuations, continuations in part and renewal applications), and any renewals, extensions or reissues thereof, in any

jurisdiction; trade secrets and registrations or applications for registration of copyrights in any jurisdiction, and any renewals or extensions thereof.

Director recognizes and agrees that any breach of this Agreement by Director will entitle Frontier, Frontier Bank and their successors or assigns to injunctive relief, as well as any other legal or equitable remedies to which such entities may otherwise be entitled, including, but not limited to damages.

If the Merger Agreement expires or is terminated for any reason before the consummation of the transactions contemplated thereunder, this Agreement will automatically terminate and be of no further force and effect.

WHEREAS, Frontier, Washington Banking Company (“WBC”) and Whidbey Island Bank (“WBC Bank”) are entering into an Agreement and Plan of Merger (“the Merger Agreement”), pursuant to which WBC will be merged into Frontier Financial Corporation and WBC Bank will be merged into Frontier Bank (the “Merger”); and

WHEREAS, Executive is currently employed as President and Chief Executive Officer of WBC and/or WBC Bank and has knowledge of certain Confidential Information of WBC, and Frontier Financial Corporation and Frontier Bank are executing the Merger Agreement conditioned upon Executive’s agreement not to compete with Frontier in any county in which WBC Bank has branch offices or loan production offices, and not to solicit employees and customers of Frontier (including the employees and customers of WBC who become employees and customers of Frontier following the Merger), for a specified period of time following the Merger, all as further described below; and

NOW, THEREFORE, Frontier and Executive agree as follows:

1. Effective Time. This Agreement shall become effective at the effective time of the Merger (the “Effective Time”), as set forth in the Merger Agreement.

2. Noncompetition, Nonsolicitation and Nondisparagement. In consideration for this Agreement and to protect the business and goodwill purchased by Frontier pursuant to the Merger Agreement, Executive agrees that he will not, directly or indirectly, do any of the following:

2.1 For a one-year period commencing on the first day after the effective time of the Merger (the “Effective Time”), (a) become involved in, as a principal shareholder, director, officer, founder, employee, consultant or other agent (each of the foregoing relationships, hereinafter referred to as an “Affiliate”) of any Financial Institution (as defined below) in any of the Washington state counties of Island, San ▇▇▇▇, Skagit, Snohomish and Whatcom (individually and collectively, the “Counties”), or (b) have any responsibility for a Financial Institution’s organization or operation in any of the Counties; provided, however, that Executive may acquire and passively own an interest not exceeding 2% of the total equity interest in any Financial Institution in any of the Counties that is traded on NASDAQ or another U.S. stock exchange. For purposes of this Agreement, the term “Financial Institution” means any bank holding company or financial holding company, state or national bank, state or federal savings and loan association, mutual savings bank, or state or federal credit union, trust company or mortgage company (including without limitation, any organizing entity of any such Financial Institution) located in any of the Counties.

2.2 For a two-year period commencing on the first day after the effective time of the Merger (the “Effective Time”), (a) solicit or attempt to solicit (i) any employees of Frontier to leave their employment, or (ii) any customers of Frontier to remove or transfer any of their business from Frontier, or (b) otherwise interfere with, disrupt or attempt to disrupt the relationship, contractual or otherwise, between Frontier and any of Frontier’s customers or employees. Solicitation prohibited under this section includes solicitation by any means, including, without limitation, meetings, letters or other mailings, electronic communications of any kind, and Internet communications; provided, however, that solicitation prohibited under this paragraph does not include solicitation through general advertising that is not specifically directed to or targeting the employees of Frontier or Frontier Bank.

3. Nondisparagement. Executive shall not, during the term or after the termination or expiration of this Agreement or Executive’s employment, make disparaging statements, in any form, about Frontier or its officers, directors, agents, employees, products or services.

4. Intellectual Property/Confidential Information. Further, anything to the contrary herein notwithstanding, neither Executive nor any firm, company, trust or other entity of which Executive is an Affiliate shall, during the term or after the termination or expiration of this Agreement, (i) use, register or claim any right or interest in any Intellectual Property or Confidential Information of Frontier, including but not limited to the Intellectual Property and Confidential Information of WBC acquired pursuant to the Merger Agreement, or (ii) use the tradename “Washington Banking Company,” “Whidbey Island Bank,” or any similar name or derivation thereof, in connection with the banking, financial, lending or mortgage industries.

5. No Employee Contract Rights. Nothing contained in this Agreement shall be construed to abrogate, limit or affect the powers, rights and privileges of Frontier to remove Executive as an employee of Frontier, with or without cause.

6. Enforcement of Covenants.

6.1 Frontier and Executive stipulate that, in light of all of the facts and circumstances of the relationship between Frontier and Executive, the covenants referred to in Sections 2, 3 and 4 (including without limitation their scope, duration and geographic extent) are fair and reasonably necessary for the protection of Frontier’s Confidential Information (as defined below), goodwill and other protectable interests. If a court of competent jurisdiction should decline to enforce any of those covenants and agreements, Frontier and Executive request the court to reform these provisions to restrict Executive’s use of Confidential Information and Executive’s ability to compete with Frontier to the maximum extent, in time, scope of activities and geography, that the court finds enforceable.

6.2 Executive acknowledges that Frontier will suffer immediate and irreparable harm that will not be compensable by damages alone, if Executive repudiates or breaches any of the provisions of Sections 2, 3 or 4. For this reason, under these circumstances, Frontier, in addition to and without limitation of any other rights, remedies or damages available to it at law or in equity, will be entitled to obtain temporary, preliminary and permanent

injunctions in order to prevent or restrain the breach, and Frontier will not be required to post a bond as a condition for the granting of this relief.

6.3 In the event Executive breaches this Agreement, which breach is not corrected within 15 days of notice by Frontier to Executive of such breach, Executive shall in addition to the remedies available to Frontier under Section 6.2, forfeit all right to receive all benefits or other payments remaining unpaid from Frontier pursuant to Section 8.2 or otherwise on the date of any such breach.

7. Adequate Consideration. Executive specifically acknowledges the receipt of adequate consideration for the covenants contained in Sections 2, 3 and 4 above and that Frontier is entitled to require him to comply with said Sections 2, 3 and 4, which Sections will survive termination of this Agreement.

8. Employment Agreement Superseded. Executive’s Employment Agreement with WBC dated as of May 6, 2005 (the “Employment Agreement”) is terminated, superseded and replaced as of the Effective Time by the following provisions:

8.1 Definitions. The following definitions shall govern and be controlling for purposes of this Agreement:

8.1.1 “Cause” shall include termination because Executive: (i) materially breached this Agreement; (ii) willfully breached or habitually neglected or breached the duties which he was required to perform under the terms of his employment with Frontier or the policies of Frontier; (iii) commits act(s) of dishonesty, theft, embezzlement, fraud or misrepresentation against Frontier or its subsidiaries; (iv) willfully and continually failed to comply with any law, rule, or regulation (other than traffic violations or similar offenses) or final cease and desist order of a regulatory agency having jurisdiction over Frontier; (v) fails to follow the reasonable directions of Frontier’s board of directors, which failure is not corrected within thirty (30) days after receipt by Executive of written notice outlining the corrective action required; or (vi) knowingly provides misleading or false information to shareholders, the board of directors, auditors, accountants, or regulatory authorities.

8.1.2 “Change of Control” means the Merger.

8.1.3 “Confidential Information” includes, without limitation, any information in whatever form that Frontier considers to be confidential, proprietary, information and that is not publicly or generally available relating to Frontier’s: trade secrets (as defined by the Uniform Trade Secrets Act); know-how; concepts; methods; research and development; product, content and technology development plans; marketing plans; databases; inventions; research data and mechanisms; software (including functional specifications, source code and object code); procedures; engineering; purchasing; accounting; marketing; sales; customer lists; advertisers; joint venture partners; financial status; contracts or employees. Confidential Information includes information developed by Executive, alone or with others, or entrusted to Frontier by its customers or others.

8.1.4 “Good Reason” shall include, but not be limited to: (i) a material reduction in Executive’s compensation defined as a reduction equal to or greater than five percent (5%) of Executive’s then annual base salary, which reduction is not of general application to substantially all employees of Frontier, (ii) a material reduction in Executive’s duties, responsibilities, or reporting relationship, but not merely a change in title, or (iii) relocation of Executive’s primary workplace from Oak Harbor to a location outside Island, San ▇▇▇▇, Snohomish, Skagit or Whatcom counties.

8.1.5 “Intellectual Property” means any material trademarks, service marks, brand names, certification marks, trade dress or other indications of origin, the goodwill associated with the foregoing and applications in any jurisdiction to register, the foregoing, including any extension, modification or renewal of any such registration or application; patents, applications for patents (including divisions, continuations, continuations in part and renewal applications), and any renewals, extensions or reissues thereof, in any jurisdiction; trade secrets and registrations or applications for registration of copyrights in any jurisdiction, and any renewals or extensions thereof.

8.1.6 “Limitation Amount” means an amount equal to two times the lesser of (i) Executive’s annualized compensation based upon the annual rate of pay for services provided to Frontier for his taxable year preceding his taxable year in which his employment with Frontier terminates (adjusted for any increase during that year that was expected to continue indefinitely if his employment did not terminate); or (ii) the maximum amount that may be taken into account under a qualified plan pursuant to section 401(a)(17) of the Code for the year in which Executive’s employment terminates. For 2007, such maximum amount is two times $225,000 (adjusted annually for increases in the cost of living) or $450,000.

8.2 Payment Obligations.

8.2.1 If Executive is an employee of WBC at the Effective Time and is retained by Frontier as an employee after the Effective Time, (i) Frontier will pay Executive 50% of his Severance Benefit (calculated pursuant to section 5 of his Employment Agreement), less statutory payroll deductions, in cash upon Closing of the Merger; and (ii) if Executive remains an employee of Frontier on the first anniversary of the Effective Time or within 12 months after the Change of Control, Frontier terminates Executive’s employment other than termination for Cause, or Executive terminates his employment with Frontier for Good Reason, Executive shall receive the balance of his Severance Benefit, less statutory payroll deductions, within 30 days following such anniversary date or the date of termination of employment; provided, however, that any amount in excess of the Limitation Amount, will be paid to him no sooner than the first day of the seventh calendar month following the termination of his employment.

8.2.2 If Executive is an employee of WBC at the Effective Time but is not retained by Frontier as an employee after the Effective Time, Frontier will pay Executive 100% of his Severance Benefit (calculated pursuant to section 5 of his Employment Agreement), less statutory payroll deductions, in cash upon Closing of the Merger; provided, however, that any amount in excess of the Limitation Amount, will be paid to him no sooner than the first day of the seventh calendar month following the termination of his employment.

8.3 Notwithstanding anything in this Agreement to the contrary, if it is determined by legal counsel (or other tax advisor to Executive) that the total of the Severance Benefit, together with any other payments or benefits paid by Frontier to Executive, would constitute an “excess parachute payment” within the meaning of section 280G of the Internal Revenue Code of 1986 (the “Code”), as amended, and the net after-tax amount that Executive would realize from such compensation, considering Executive’s federal and state income tax brackets and the excise tax, would be greater if the compensation payable hereunder were limited, then the compensation payable hereunder shall be limited in the manner determined by such counsel or advisor, to maximize Executive’s net after-tax income.

8.4 Where required, the provisions of this Agreement are intended to comply with the requirements of section 409A of the Code. Notwithstanding any other provision of this Agreement, this Agreement shall be interpreted and administered in accordance with the requirements of section 409A of the Code.

8.5 Any payment to Executive under Section 8.2 hereof shall be conditioned upon receipt by Frontier of an executed release of all claims against Frontier, satisfactory to Frontier and its counsel.

9. Miscellaneous Provisions.

9.1 Independent Legal Counsel. Executive acknowledges that he has had the opportunity to review and consult with his own personal legal counsel regarding this Agreement.

9.2 Binding Effect. This Agreement will bind and inure to the benefit of Frontier’s and Executive’s heirs, legal representatives, successors and assigns.

9.3 Costs of Legal Actions and Proceedings. In any dispute between the parties arising out of or under this Agreement, whether or not a lawsuit is commenced, the nonprevailing party shall pay the prevailing party’s reasonable attorneys’ fees and costs.

9.4 Governing Law. This Agreement shall be construed in accordance with and governed and enforced in all respects by the laws of the state of Washington. The parties agree that venue of any legal action between the parties arising out of or in connection with this Agreement shall be with the competent state or federal court in Washington state, unless otherwise elected by Frontier, its successors or assigns.

9.5 Entire Agreement. This Agreement contains the entire agreement of the parties with respect to its subject matter, and supersedes all prior representations and understandings, whether oral or written. It may be changed only by an agreement in writing signed by the party against whom enforcement of any waiver, amendment, modification, extension or discharge is sought.

9.6 Waiver. No waiver of any term, condition or provision shall be effective for any purpose whatsoever unless such waiver is in writing and signed by the parties.

9.7 Severability. The provisions of this Agreement are severable. The invalidity of any provision will not affect the validity of other provisions of this Agreement.

9.8 Notice. Any notice to be delivered under this Agreement shall be given in writing and delivered personally or by certified mail, postage prepaid, addressed to Frontier or to Executive at their last known address.

9.9 Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed an original, but all of which taken together will constitute one and the same instrument.

IN WITNESS WHEREOF, the undersigned have set their hands as of the date first written above.

Ladies and Gentlemen:

I have been advised that as of the date hereof I may be deemed an “affiliate” of Washington Banking Company (“WBC”), as the term “affiliate” is defined for purposes of paragraphs (c) and (d) of Rule 145 of the rules and regulations (the “Rules and Regulations”) under the Securities Act of 1933, as amended (the “Act”). Pursuant to the terms of the Agreement and Plan of Merger among Frontier Financial Corporation (“Frontier”), Frontier, WBC and Whidbey Island Bank (the “Agreement”), WBC will be merged into Frontier (the “Merger”). As a result of the Merger, I will receive shares of common stock of Frontier (“Frontier Common Stock”) in exchange for shares of common stock of WBC (“WBC Common Stock”) owned by me.

In connection with the above, I represent and warrant to Frontier and agree that:

A. I will not make any sale, transfer or other disposition of the shares of Frontier Common Stock that I receive in the Merger in violation of the Act or the Rules and Regulations.

B. I have no present plan or intent to dispose of Frontier Common Stock acquired by me pursuant to the Merger.

C. I have been advised that the issuance of shares of Frontier Common Stock to me pursuant to the Merger has been or will be registered with the Securities and Exchange Commission under the Act on Form S-4. I have also been advised, however, that since I may be deemed to be an affiliate of WBC at the time the Agreement is submitted for a vote of the shareholders of WBC, I may not sell, transfer or otherwise dispose of the shares of Frontier 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 145 under the Act, or (iii) in the opinion of counsel acceptable to Frontier, some other exemption from registration under the Act is available with respect to any such proposed sale, transfer or other disposition of the shares of Frontier Common Stock.

D. I have carefully read this letter and the Agreement and have discussed their requirements and other applicable limitations upon my ability to sell, transfer or otherwise dispose of the shares of Frontier Common Stock, to the extent I felt necessary, with my counsel or counsel for WBC.

E. I understand that Frontier is under no obligation to register the shares of Frontier Common Stock for sale, transfer or other disposition by me or on my behalf under the Act or to take any other action necessary in order to make compliance with an exemption from registration available, except that Frontier has agreed to use its best efforts to maintain the availability of Rule 145 for use by affiliates such as me.

F. I understand that stop transfer instructions will be given to the registrar of the certificates for the shares of Frontier Common Stock and there will be placed on the certificates for the shares of Frontier Common Stock, or any substitutions therefor, legends stating in substance:

The shares represented by this certificate were issued in a merger (the acquisition of Washington Banking Company) to which Rule 145 promulgated under the Securities Act of 1933, as amended (the “Act”), applies and may be sold or otherwise transferred only in compliance with the limitation of such Rule 145, or upon receipt by Frontier of an opinion of counsel acceptable to it that some other exemption from registration under the Act is available, or pursuant to a registration statement under the Act.

G. I hereby agree that, for a period of one (1) year following the effective date of the Merger, I will obtain an agreement similar to this agreement from each transferee of the shares of Frontier Common Stock sold or otherwise transferred by me, but only if such transfer is effected other than in a merger involving a registered public offering or as a sale pursuant to Rule 145.

It is understood and agreed the legend set forth in Paragraph F above will be removed by delivery of substitute certificates without such legend if such legend is not required for purposes of the Act or this Agreement. It is understood that such legend and stop order referred to above will be removed if (i) one year shall have elapsed from the date the undersigned acquired Frontier Common Stock received in the Merger and the provisions of Rule 145(d)(2) are then available to the undersigned; (ii) two years shall have elapsed from the date the undersigned acquired Frontier Common Stock received in the Merger and the provisions of Rule 145(d)(3) are then available to the undersigned; or (iii) Frontier has received either an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to Frontier, or a “no action” letter obtained by the undersigned from the staff of the Securities and Exchange Commission, to the effect that the restrictions imposed by Rule 145 under the Act no longer apply to the undersigned.

This letter agreement shall be binding on my heirs, legal representatives and successors.

Ladies and Gentlemen:

We have acted as counsel to Frontier Financial Corporation (“Frontier”) and its subsidiaries (collectively “Frontier”), in connection with the Agreement and Plan of Merger (the “Agreement”), dated as of September ___, 2007, between Frontier, Frontier Bank, Washington Banking Company and Whidbey Island Bank, and the transactions contemplated by the Agreement.

This firm has represented Frontier and Frontier Bank in connection with the negotiation of the Agreement and matters related to such negotiation and with respect to certain limited matters as to which we have been consulted by them. We are familiar with the corporate proceedings taken by Frontier and Frontier Bank in connection with the Agreement, and we are rendering this opinion pursuant to Section 7.3(D) of the Agreement. Capitalized terms used, but not defined, in this opinion letter shall have the meanings assigned to them in the Agreement.

In rendering the opinions expressed below, we have examined and relied upon such records, documents, instruments, certificates of public officials and certificates of officers and employees of and accountants for Frontier and Frontier Bank as we have deemed appropriate, including:

existence or authorization dated ___, 2007, issued by the Washington Department of Financial Institutions with respect to Frontier Bank.

Whenever any statement in this opinion letter is qualified by the phrase “to our knowledge” or “known to us” or similar phrases, it is intended to indicate that, during the course of our representation of Frontier in connection with the transactions contemplated by the Agreement, no information that would give us actual knowledge of the inaccuracy of such statement has come to the attention of the attorneys presently in this firm who are actively engaged in the representation of Frontier. We have not undertaken any independent investigation or review (including any investigation or review of our files) in connection with any such matters to determine the accuracy of any such statement, and any limited inquiry undertaken by us during the preparation of this opinion letter should not be regarded as such investigation or review.

In conducting our examination, we have assumed, without investigation, the genuineness of all signatures, the legal capacity of natural persons, the correctness of all certificates, the authenticity of all documents and instruments submitted to us as originals, the conformity to original documents and instruments of all such documents and instruments submitted to us as certified or photostatic or facsimile copies and the authenticity of the originals of such copies, and the accuracy and completeness of all records made available to us by Frontier. We also have assumed, without investigation, that (i) each party to such documents and instruments has the power and capacity to execute, deliver and perform all of its obligations under the documents and instruments, has duly authorized the execution, delivery and performance of its obligations under the Agreement, and has duly executed and delivered the documents and instruments; (ii) all terms, provisions, and conditions of, or relating to, the Agreement are correctly and completely reflected in the Agreement, and all statements, representations, and warranties as to factual matters made by officers and employees of and accountants for, Frontier and by public officials are accurate; and (iii) the Agreement is binding upon and enforceable in accordance with its terms against Washington Banking Company and Whidbey Island Bank.

The opinions expressed below are subject to the following qualifications:

Our opinion as to the legal, valid and binding nature of the Agreement and the enforceability of the Agreement in paragraphs 4, 5 and 6 below is subject to the following: (i) the effect of applicable bankruptcy, insolvency, reorganization, receivership, fraudulent conveyance, moratorium or other similar laws affecting the rights of creditors generally, including without limitation such laws and/or regulations specifically applicable to institutions the deposits of which are insured by the Federal Deposit Insurance Corporation (“Insured Institutions”), now or subsequently in effect; (ii) limitations imposed by laws and judicial decisions relating to or affecting creditors of Insured Institutions, or by general principles of equity (regardless of whether enforcement is considered in proceedings at law or in equity), upon the provisions of the Agreement and/or the other related documents or upon the availability of injunctive relief or other equitable remedies; and (iii) our assumption that Washington Banking Company and Whidbey Island Bank and any of their successors in interest will seek to enforce any of its rights

in connection with the Agreement only in circumstances and in a manner in which it is commercially reasonable to do so.

B. We express no opinion as to: (i) the enforceability of any provision or accumulation of provisions that may be deemed to be unconscionable; (ii) any antitrust, securities or tax laws; (iii) provisions that purport to establish evidentiary standards; (iv) provisions relating to venue, jurisdiction, governing law, waiver of remedies (or the delay or omission of enforcement of such provisions), or disclaimers or liability limitations with respect to third parties; (v) the enforceability of any requirement in the Agreement or related documents specifying that provisions of such documents may only be waived in writing, to the extent that an oral agreement or an implied agreement by trade practice or course of conduct has been created modifying any provision of the Agreement; (vi) provisions for payment or reimbursement of costs and expenses (including, without limitation, attorneys fees) in excess of statutory limits or amounts determined to be reasonable by any court or other tribunal, and any provision for payment of attorneys fees other than to the prevailing party; (vii) severability and indemnification provisions; (viii) availability of equitable remedies; and (ix) any reservation of the right to pursue inconsistent or cumulative remedies.

C. Our opinions below are limited to the matters expressly set forth in this opinion letter, and no opinion is to be implied or may be inferred beyond the matters expressly so stated.

D. We disclaim any obligation to update this opinion letter for events occurring after the date of this opinion letter.

E. Our opinions below are limited to the effect of the laws of the United States of America and the State of Washington. We express no opinion with respect to the effect of the laws of any other jurisdiction on the transactions contemplated by the Agreement.

F. A Washington court, or federal court applying Washington law, may consider extrinsic evidence or the circumstances surrounding the making of the Agreement to ascertain the intent of the parties using the language employed in the Agreement, regardless of whether or not the language used is plain and unambiguous on its face, and may incorporate additional or supplementary terms into the Agreement.

Based upon and subject to the foregoing, we are of the opinion that:

1. Frontier is a corporation validly existing under the laws of the State of Washington and has the corporate power to own or lease its properties and assets and to carry on its business as such properties, assets and business are described in the Proxy Statement.

2. Frontier Bank is a banking corporation validly existing under the laws of the State of Washington and has the corporate power to own or lease its properties and assets and to carry on its business as such properties, assets and business are described in the Proxy Statement.

4. The Agreement constitutes a valid and binding obligation of Frontier and Frontier Bank, enforceable against Frontier and Frontier Bank in accordance with its terms.

5. No consent or approval that has not already been obtained from any federal or state regulatory authority is required for the execution and delivery by Frontier and Frontier Bank of the Agreement or any of the documents to be executed and delivered by Frontier and Frontier Bank in connection with the Agreement or for the consummation of the Merger.

Neither the execution delivery or performance of the Agreement by Frontier and Frontier Bank nor the consummation of the Merger will: (a) violate any provision of the articles or bylaws of Frontier or Frontier Bank; or (b) to our knowledge, violate any order, judgment or decree to which Frontier or Frontier Bank is a party or by which any of its properties or assets is bound.

7. The shares of Frontier Common Stock to be issued pursuant to the Agreement to the shareholders of Washington Banking Company will, upon issuance in accordance with the Agreement, be duly authorized, validly issued, fully paid and non-assessable and issued in compliance with all registration requirements or exemptions therefrom under applicable federal and state securities laws..

8. The Registration Statement registering the shares of Frontier Common Stock to be issued to shareholders of Washington Banking Company pursuant to the Agreement has become effective under the Securities Act of 1933, as amended (the “Securities Act”), and, to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and, to our knowledge, no proceedings for that purpose have been instituted or are pending or contemplated by the Securities and Exchange Commission or any state securities or other regulatory authority.

9. To our knowledge there is no suit, action, investigation or proceeding, legal, quasi-judicial, administrative or otherwise, pending or threatened against, or affecting Frontier or Frontier Bank or any of their directors, officers, employees or agents, acting in their capacities as such, that is seeking equitable relief or damages against Frontier or Frontier Bank or any of their directors, officers, employees or agents acting in their capacities that would materially affect the ability of Frontier or Frontier Bank to consummate the transactions contemplated by the Agreement or that seeks to enjoin consummation of the transactions contemplated by the Agreement.

In the course of the preparation of the Proxy Statement, we have considered the information set forth in the Proxy Statement, and have participated in conferences with officers

We have relied as to materiality upon the judgment of officers and representatives of Frontier and Frontier Bank. On the basis of the foregoing, we confirm that nothing has come to our attention that would lead us to believe that the Proxy Statement, insofar as it relates to Frontier and Frontier Bank, on the mailing date of the Proxy Statement, contained any statement that, at the time and in light of the circumstances in which it was made, was false or misleading with respect to any material fact or omitted to state any material fact necessary to make such statements not false or misleading. We make no statement with respect to (a) material in the Proxy Statement insofar as it includes or reflects any information relating to or supplied by entities other than Frontier and Frontier Bank, or (b) any financial statements or other financial or accounting data contained in the Proxy Statement.

The foregoing is rendered solely for your benefit in connection with the above-described transactions.

D-3		Our opinions below are limited to the matters expressly set forth in this opinion letter, and no opinion is to be implied or may be inferred beyond the matters expressly so stated.

D-4		We disclaim any obligation to update this opinion letter for events occurring after the date of this opinion letter.

D-5		A Washington court, or federal court applying Washington law, may consider extrinsic evidence of the circumstances surrounding the making of the Agreement to ascertain the intent of the parties using the language employed in the Agreement, regardless of whether or not the language used is plain and unambiguous on its face, and may incorporate additional or supplementary terms into the Agreement.

E. Certain Factual Matters

In the course of the preparation of the Proxy Statement, we have considered the information set forth in the Proxy Statement, and have participated in conferences with officers and other representatives of WBC and WBC Bank, during the course of which the contents of the Proxy Statement and related matters were discussed; however, we were not directed to establish, and we did not independently establish, matters of fact.

The preparation of the Proxy Statement involved many determinations of fact, points of information or other non-legal matters, and we did not independently verify, and do not assume any responsibility for, the accuracy, completeness or fairness of the Proxy Statement. As used in this Part E, when a statement is qualified by the term “material,” such statements involve judgments and opinions as to the materiality or lack of materiality of any matter related to WBC’s or WBC Bank’s business, assets, results of operations or financial condition that are entirely those of WBC, WBC Bank and its officers, after having been advised by us as to the legal effect and consequences of such matters, and such opinions and judgments are not known to us to be incorrect. We offer no assurance that the actions taken in connection with the preparation and review of the Proxy Statement were sufficient to cause the Proxy Statement to be accurate, complete or fair.

Based upon our procedures identified above (relying as to matters of fact to a large extent on statements of officers and other representatives of WBC and WBC Bank) and without expressing an opinion thereon, nothing has come to our attention that has caused us to conclude that the Proxy Statement (as of the time it was declared effective), contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading. We make no statement with respect to (a) material in the Proxy Statement insofar as it includes or reflects any information relating to or supplied by entities other than WBC or WBC Bank, or (b) any financial statements or other financial or accounting data contained in the Proxy Statement.

The foregoing is rendered solely for your benefit in connection with the above-described transactions. You may not, without our prior express written approval, deliver copies of this letter or extracts from this letter to any other person, and no one other than you is entitled to rely upon the opinions set forth above.


		Very truly yours,

Re: Corporate Merger/Tax Consequences

Ladies and Gentlemen:

This letter responds to your request for our opinion as to certain of the federal income tax consequences of the proposed merger (the “Merger”) of Washington Banking Company (“WBC”) into Frontier Financial Corporation (“Frontier”) in exchange for cash and Frontier common stock. The time at which the Merger becomes effective is hereafter referred to as the “Effective Date.” This opinion is being delivered in connection with Frontier’s registration statement on Form S-4 relating to the proposed Merger (the “Registration Statement”) to which this opinion appears as an exhibit.

We have acted as legal counsel to Frontier in connection with the Merger. In acting as counsel to Frontier in connection with the Merger, we have, in preparing our opinion, as hereinafter set forth, participated in the preparation of the Merger Agreement and the preparation and filing of the Registration Statement. For the purpose of rendering this opinion, we have examined and relied upon originals, certified copies, or copies otherwise identified to our satisfaction as being true copies of the originals of the following documents, including all exhibits and schedules attached to them:

	1.		The Agreement and Plan of Merger dated as of September ___, ▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇ and Whidbey Island Bank (the “Merger Agreement”).

	2.		Form S-4 Registration Statement and Prospectus of Frontier filed with the Securities and Exchange Commission on or about ___, 2007.

	3.		The Proxy Statement of WBC (included as part of the Registration Statement).

Such other documents, instruments, records and information pertaining to the Merger as we have deemed necessary for rendering our opinion.

We have assumed, without independent investigation or review, the accuracy and completeness of the facts and representations and warranties contained in those documents or otherwise made known to us through the Effective Date of the Merger, and that the Merger will be effected in accordance with the terms of the Merger Agreement.

Our opinion is based on the Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations, administrative interpretations, and judicial precedents as of the date hereof. If there is any subsequent change in the applicable law or regulations, or if there are subsequently any new applicable administrative or judicial interpretations of the law or regulations, or if there are any changes in the facts or circumstances surrounding the Merger, the opinion expressed herein may become inapplicable.

Based upon our review of the facts described above and our analysis of the law, and subject to the qualifications and limitations set forth herein, and the completion of the transactions described in the manner contemplated by the Merger Agreement, it is our opinion that:

A. The Merger will be treated as a reorganization under Section 368(a)(1)(A) of the Code and Frontier and WBC will each be a party to that reorganization within the meaning of Section 368(b) of the Code; provided, however, that at least fifty percent (50%) of the sum of (1) the Aggregate Consideration (as defined in section 1.3(A) of the Merger Agreement) payable in cash and Frontier common stock to the WBC shareholders in the Merger and (2) any additional cash paid to holders of dissenting shares pursuant to Section 1.6 of the Merger Agreement, is paid in Frontier common stock.

B. Provided the Merger satisfies the condition in the foregoing paragraph that at least 50% of the total consideration for the Merger is paid in Frontier common stock, it is further our opinion that the material federal income tax consequences of the Merger will be:

1. Parties. No gain or loss will be recognized by Frontier or WBC as a result of the Merger.

2. Shareholders of WBC. We hereby confirm our opinion set forth in the discussion contained in the Registration Statement under the caption “The Merger — Certain Federal Income Tax Consequences”.

We express our opinion herein only as to those matters specifically set forth above and no opinion should be inferred as to the tax consequences of the Merger under any state, local or foreign law, or with respect to other areas of United States federal taxation. We are members of the Bar of the State of Washington, and we do not express any opinion herein concerning any law other than the federal law of the United States.

Our opinion is intended solely for the benefit of Frontier and WBC, and their respective shareholders, and may not be relied upon for any other purpose or by any other person or entity or made available to any other person or entity without our prior written consent.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and the reference to us in the Proxy Statement/Prospectus under the heading “The Merger — Certain Federal Income Tax Consequences” and “Legal Opinions.” By giving the foregoing consent, we do not admit that we come within the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules and regulations of the Securities and Exchange Commission thereunder.
