W I T N E S S E T H:

WHEREAS, the parties desire that Merger Sub be merged with and into the Company (the “Merger”) pursuant to which the Company will become a wholly-owned Subsidiary of Buyer; and

WHEREAS, the respective Boards of Directors of Buyer, Merger Sub and the Company have approved this Agreement and the Merger.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

ARTICLE I
THE MERGER

Section 1.1 The Merger. Upon the terms and subject to the conditions hereof, and in accordance with the Washington Business Corporation Act (the “WBCA”), Merger Sub will be merged with and into the Company at the Effective Time. Following the Effective Time, the separate corporate existence of Merger Sub will cease and the Company will continue as the surviving corporation (the “Surviving Corporation”) and will succeed to and assume all the rights and obligations of Merger Sub and the Company in accordance with the WBCA.

Section 1.2 Closing. The closing of the Merger will take place at 9:00 a.m. on a date mutually agreed to by Buyer and the Company, which will be no later than the business day after satisfaction or waiver of the conditions set forth in Article VII (the “Closing Date”), at the offices of Xxxxxxx Xxxxx & Xxxxx LLP, Seattle, Washington, unless another date, time or place is agreed to in writing by Buyer and the Company.

Section 1.3 Effective Time. The Merger will become effective (the “Effective Time”) upon the later of (a) the date of filing of properly executed Articles of Merger (the “Articles of Merger”) relating to the Merger with the Secretary of State of Washington in accordance with the WBCA, and (b) at such other time as Buyer and the Company agree and set forth in the Articles of Merger.

Section 1.4 Effects of the Merger. The Merger will have the effects set forth in this Agreement and in the WBCA.

Section 1.5 Articles of Incorporation and Bylaws; Officers and Directors.

(a) The Articles of Incorporation of the Company, as in effect immediately prior to the Effective Time, will be the Articles of Incorporation of the Surviving Corporation until thereafter changed or amended as provided therein and by applicable law.

(b) The bylaws of the Company, as in effect immediately prior to the Effective Time, will be the bylaws of the Surviving Corporation until thereafter changed or amended as provided by the Surviving Corporation’s Articles of Incorporation, bylaws and by applicable law.

(c) The directors and officers of Merger Sub immediately prior to the Effective Time will be the directors and officers of the Surviving Corporation, until their respective successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Surviving Corporation’s Articles of Incorporation and bylaws and by applicable law.

ARTICLE II
EFFECT OF THE MERGER; CONVERSION OF SHARES

Section 2.1 Effect on Company Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of any of Buyer or the Company or the holders of any securities thereof:

(a) Cancellation of Certain Shares. Each share of Common Stock, $1.00 par value per share, of the Company (“Company Common Stock,”) that (i) has been reacquired by the Company and is held as authorized but unissued Company Common Stock, (ii) is owned by any Subsidiary of the Company or (iii) is owned by Buyer or any Subsidiary of Buyer, will automatically be cancelled and retired and will cease to exist, and no consideration will be delivered in exchange therefor. “Subsidiary” of any Person means another Person, an amount of the voting securities, other voting ownership or voting partnership interests of which is sufficient to elect at least a majority of its Board of Directors or other governing body (or, if there are no such voting interests, greater than 50% of the equity interests of which) is owned directly or indirectly by such first Person.

(b) Conversion of Company Common Shares. Each share of Company Common Stock issued and outstanding, including Company Stock Options deemed exercised pursuant to Section 2.2, (but not Dissenting Shares and shares of Company Common Stock to be cancelled in accordance with Section 2.1(a)) (the “Company Common Shares”) will be converted into the right to receive $26.50 in cash, without interest (the “Merger Consideration”) on the terms set forth in this Agreement. All such Company Common Shares, when so converted, will no longer be outstanding and will automatically be cancelled and retired, and each holder of a certificate representing any such Company Common Shares will cease to have any rights with respect thereto, except the right to receive Merger Consideration without interest upon the surrender of the proper documentary evidence to the Paying Agent in accordance with Section 2.4(c).

Section 2.2 Effect on Company Options and Other Company Securities; Suspension of DRIP and Employee Savings Plans.

(a) Immediately prior to the Effective Time, contingent on consummation of the Closing, each outstanding option to purchase Company Common Stock (a “Company Stock Option”) that is outstanding immediately prior to the Effective Time pursuant to the Company’s 1998 Stock Incentive Plan (including the Company’s 2000 Director Stock Award Plan (the “Director Stock Plan”)) (collectively, the “Company Option Plan”) that is not vested, will immediately vest and become exercisable by the holder. If this Agreement is terminated, all Company Stock Options that were otherwise unvested will revert to their original status. The Company will exercise reasonable efforts to cause all holders of Company Stock Options to either exercise such options or irrevocably waive his or her rights to do so. At the Effective Time, each Company Stock Option with respect to which the holder has delivered to the Company a proper exercise notice will be considered exercised. The Common Stock issuable in respect of such exercise will be deemed issued without the necessity of issuing a stock certificate and will be treated as Company Common Shares in the Merger. The Paying Agent, on Buyer’s behalf, will deduct the exercise price payable in connection with the exercise of Company Stock Options from the Merger Consideration otherwise payable in respect of the Company Common Shares deemed issued in respect of the exercised option; it will not be necessary for holders of Company Stock Options to tender the exercise price. Any Company Stock Options with respect to which the Payment Agent has not received notice of exercise before termination of the Payment Fund will be cancelled.

(b) At the Effective Time, all remaining restrictions with respect to shares of Company restricted stock issued pursuant to the Company Option Plan (the “Company Restricted Shares”) will expire and all of the Company Restricted Shares will be fully vested and will be treated as Company Common Shares in the Merger, provided, however, that the amount payable by the Paying Agent in respect of such Company Common Shares shall be reduced by all applicable federal, state and local Taxes required to be withheld by the Company or otherwise with respect thereto.

(c) Prior to the record date for the Company Shareholders Meeting, the Company will take such actions and enter into such agreements to cause (i) all outstanding Stock Units (as defined in the Director Stock Plan) (the “Company Stock Units”) to be cancelled and (ii) to be issued to each holder of Company Stock Units a number of Company Common Shares equal to number of Company Stock Units such Person holds, which will be treated as Company Common Shares in the Merger, in each case to be effective immediately prior to the Effective Time.

(d) Prior to the Effective Time, the Company will cause the Company’s Automatic Dividend Reinvestment Plan (the “Company DRIP”) and all rights thereunder to be suspended immediately following the Investment Date (as defined in the Company DRIP) ending immediately prior to the Effective Time, with the effect of such suspension being that no offering period will commence or continue under such plan during the period of such suspension.

(e) Prior to the Effective Time, the Company will cause the Company’s Employee Retirement Savings Plan (2002 Restatement) (the “Company Employee Savings Plan” and,

collectively with the Company Option Plan and the Company DRIP, the “Company Stock Plans”), to be amended to suspend investments in Qualifying Employer Securities (as defined therein) effective as of the last business day prior to the Effective Time.

Section 2.3 Conversion of Merger Sub Common Shares. Each share of common stock, no par value, of Merger Sub issued and outstanding immediately prior to the Effective Time will, by virtue of the Merger and without any action on the part of the holder thereof, be converted into and exchangeable for one (1) share of common stock of the Surviving Corporation and each certificate evidencing ownership of any shares of common stock of Merger Sub shall evidence ownership of the same number of shares of common stock of the Surviving Corporation.

Section 2.4 Payment Procedures.

(a) Payment Agent; Payment Fund. Not less than five business days prior to the Effective Time, Buyer will authorize a banking or other financial institution selected by Buyer and reasonably satisfactory to the Company to act as Payment Agent hereunder (the “Payment Agent”) with respect to the Merger. At or prior to the Effective Time, Buyer will deposit, or will cause to be deposited, with the Payment Agent, for the benefit of the holders of Company Common Shares, for exchange in accordance with this Article II, the aggregate Merger Consideration payable in connection with the Merger (the “Payment Fund”). Such funds shall be invested by the Payment Agent as directed by the Surviving Corporation, provided that such investments shall be in obligations of or guaranteed by the United States of America or any agency or instrumentality thereof, in commercial paper obligations rated A-1 or P-1 or better by Xxxxx’x Investors Services, Inc. or Standard & Poor’s Corporation, respectively, or in certificates of deposits, bank repurchase agreements or banker’s acceptances of commercial banks with capital exceeding $500,000,000; provided however that (i) none of the foregoing will affect Buyer’s obligation to pay the Merger Consideration as set forth in this Section 2.4 and (ii) Buyer and the Surviving Corporation will promptly replace any losses relating to the aggregate Merger Consideration. Any net profit resulting from, or interest or income produced by, such investments will be payable to Buyer. The Payment Agent will, pursuant to irrevocable instructions of the Buyer, deliver the applicable Merger Consideration pursuant to this Article II out of the Payment Fund. At or prior to the Effective Time, the Company will provide to the Payment Agent a certified ledger setting forth the names and amounts held by the holders of all Company Stock Options. The Payment Fund will not be used for any purpose other than as set forth in this Section 2.4(a).

(b) Instructions. Promptly after the Effective Time, the Surviving Corporation will cause the Payment Agent to mail to each holder of record of Company Common Shares (i) a letter of transmittal (which will specify that delivery will be effected, and risk of loss and title to the Certificates will pass, only upon delivery of the Certificates to the Payment Agent and will be in a form and have such other provisions as Buyer may specify and that are acceptable to the Company) and (ii) instructions for use in effecting the surrender of the Certificates and shares that are held in book-entry form (“Book-Entry Shares”) in exchange for the consideration contemplated hereby, if not previously surrendered. “Certificate” means a stock certificate representing the applicable holder’s Company Common Shares or, in the case of Company Stock

Options exercised for Company Common Shares pursuant to Section 2.2, the holder’s applicable stock option agreement together with the proper executed exercise notice.

(c) Procedures. Upon surrender of a Certificate for cancellation to the Payment Agent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Payment Agent, the holder of such Certificate or Book-Entry Shares will be entitled to receive in exchange therefor the Merger Consideration that such holder has the right to receive in respect of the Certificate or Book-Entry Shares surrendered pursuant to the provisions of this Article II, after giving effect to any required withholding Tax. In the event of a transfer of ownership of Company Common Shares that is not registered in the Company’s transfer records, a check for the Merger Consideration to be paid pursuant to this Section 2.4, if applicable, may be issued to such a transferee if such Certificate or Book-Entry Shares are properly endorsed (as applicable) or otherwise be in proper form for transfer and the transferee will pay any transfer or other Taxes required by reason of the payment to any person, employee, individual, corporation, limited liability company, partnership, trust, or any other non-governmental entity (including any foreign entity) or any governmental or regulatory authority or body (including any foreign entity) (each a “Person”), other than the registered holder of such Certificate or Book-Entry Shares, or establish to the satisfaction of the Surviving Corporation that such Tax has been paid or is not applicable.

(d) Tax Withholding. Each of the Surviving Corporation, Buyer, Merger Sub and the Payment Agent will be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement (without duplication) such amounts as it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Code”) or under any provision of state, local or foreign Tax law and to pay such amounts to the applicable taxing authority. To the extent that amounts are so withheld by the Surviving Corporation, Buyer, Merger Sub or the Payment Agent, as the case may be, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made. “Tax” means: (i) any federal, state, local or foreign net income, gross income, gross receipts, windfall profit, severance, property, production, sales, use, license, excise, franchise, employment, payroll, estimated, withholding, alternative or add-on minimum, ad valorem, value-added, transfer, stamp, or environmental (including taxes under Section 59A of the Code) tax, or any other tax, custom, duty, governmental fee or other like assessment or charge of any kind whatsoever, together with any interest or penalty, addition to tax or additional amount imposed by any governmental authority and (ii) any liability in respect of any items described in clause (i) payable by reason of contract, assumption, transferee liability, operation of law, Treasury Regulation 1.1502-6(a) (or any predecessor or successor thereof or any analogous or similar provision under law) or otherwise.

(e) No Further Ownership Rights in Shares. All Merger Consideration paid upon the surrender of Certificates in accordance with the terms of this Article II will be deemed to have been issued in full satisfaction of all rights pertaining to the Company Common Shares theretofore represented by such Certificates or Book-Entry Shares. At the Effective Time, the Company’s stock transfer books will be closed, and there will be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Company Common

Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Payment Agent for any reason, they will be cancelled as provided in this Article II.

(f) Termination of Payment Fund. Any portion of the Payment Fund (including the proceeds of any investments thereof) which remains undistributed to the holders of Company Common Shares for 12 months after the Effective Time may be delivered to Buyer upon its demand, and any holder of Company Common Shares who has not theretofore exchanged such holder’s Certificate(s) or Book-Entry Shares in accordance with this Article II and the instructions set forth in the letter of transmittal mailed to such holders after the Effective Time will thereafter look only to Buyer or its agent (subject to abandoned property, escheat or other similar laws) for payment of their Merger Consideration deliverable in respect of each Company Common Share such shareholder holds as determined pursuant to this Agreement.

(g) No Liability. None of Buyer, the Surviving Corporation, the Company or the Payment Agent will be liable to any Person in respect of any amount properly delivered or deliverable to a public official pursuant to any applicable abandoned property, escheat or other similar law.

Section 2.5 Dissenting Shares. Shares of Company Common Stock issued and outstanding immediately prior to the Effective Time (but not Company Common Shares deemed issued for exercised Company Stock Options pursuant to Section 2.2) that are held by a holder who (a) has not voted such shares in favor of the adoption of this Agreement and the Merger, (b) is entitled to, and who has, properly demanded and perfected dissenter’s rights for such Company Common Shares in accordance with the WBCA and (c) has not effectively withdrawn or forfeited such dissenter’s rights prior to the Effective Time (the “Dissenting Shares”), will not be converted into a right to receive Merger Consideration at the Effective Time. If, after the Effective Time, such holder fails to perfect or withdraws, forfeits or otherwise loses such holder’s dissenter’s rights, (i) such Company Common Shares will be treated as if they had been converted as of the Effective Time pursuant to Section 2.1(b), without any interest therefor, and (ii) the procedures in Section 2.4 will apply with respect to the payment of Merger Consideration with regard to such Company Common Shares. The Company will give Buyer prompt notice of any written notice received by the Company for dissenter’s rights with respect to Company Common Shares, and Buyer will have the right to participate in all negotiations and proceedings with respect to such demands. The Company will not, except with the prior written consent of Buyer, make any payment with respect to, or settle or offer to settle, any such demands.

Section 2.6 Lost Certificates. If any Certificate has 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 the Surviving Corporation or the Payment Agent, the posting by such Person of a bond, in such reasonable amount as Surviving Corporation or the Payment Agent may direct as indemnity against any claim that may be made against them with respect to such Certificate, the Payment Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration in respect thereof pursuant to this Agreement.

Section 2.7 Adjustment of Merger Consideration. In the event that the Company changes, or establishes a record date for changing, the number of shares of Company Common Stock issued and outstanding as a result of a stock split, stock dividend, recapitalization, subdivision, reclassification, combination or similar transaction and the record date therefor is or will be prior to the Effective Time, the Merger Consideration will be appropriately, equitably and proportionately adjusted in light of such stock split, stock dividend, recapitalization, subdivision, reclassification, combination or similar transaction.

ARTICLE III
REPRESENTATIONS AND WARRANTIES OF THE COMPANY

The Company represents and warrants to Buyer, except as set forth in the Company Disclosure Schedules dated as of the date hereof (the “Company Disclosure Schedules”), and except as disclosed in the documents (excluding any exhibits or portions thereof) filed with or furnished to the Securities and Exchange Commission (the “SEC”) by the Company and publicly available on the Electronic Data Gathering, Analysis and Retrieval System prior to the date of this Agreement (the “Company Filed SEC Documents”) (it being understood that any matter set forth in the Company Filed SEC Documents will be deemed to qualify any representation or warranty in this Article III only to the extent that the description of such matter in the Company Filed SEC Documents is made in such a way as to make its relevance to the information called for by such representation or warranty readily apparent), as follows:

Section 3.1 Organization. The Company is validly existing under the laws of the State of Washington and has all requisite power and authority to carry on its businesses as now being conducted, except where the failure to be so existing or to have such power and authority would not, individually or in the aggregate, have a Company Material Adverse Effect. The Company is duly qualified or licensed to do business and in good standing (as applicable) in each jurisdiction in which the nature of its businesses or the ownership or leasing of its properties makes such qualification or licensing necessary, except in such jurisdictions where the failure to be so duly qualified or licensed and in good standing (as applicable) would not, individually or in the aggregate, have a Company Material Adverse Effect. The Company has made available to Buyer complete and correct copies of its Articles of Incorporation and bylaws. “Company Material Adverse Effect” means any event, effect, change or development that, individually or in the aggregate with other events, effects, changes or developments (i) is, or would reasonably be expected to be, material and adverse to the financial condition, business, assets, liabilities (contingent or otherwise), operations or results of operations of the Company and its Subsidiaries taken as a whole or (ii) has, or would reasonably be expected to have, a material and adverse effect on the ability of the Company to perform its obligations under this Agreement or to consummate the transactions contemplated hereby by the End Date; provided, however, that to the extent any event, effect, change or development is caused by or results from any of the following, in each case, it will not be taken into account in determining whether there has been (or would reasonably be expected to be) a Company Material Adverse Effect: (A) general economic, legal or regulatory conditions affecting the gas utility industry as a whole, except to the extent the Company and its Subsidiaries, taken as a whole, are materially and adversely affected in a disproportionate manner as compared to comparable gas utilities; (B) the

announcement of the execution of this Agreement; (C) any failure by the Company to meet any revenue or earnings predictions prepared by the Company or revenue or earnings predictions of equity analysts or the receipt by the Company or any of its Subsidiaries of any credit ratings downgrade (it being understood that the facts or occurrences giving rise or contributing to any such effect, event, change or development which affect or otherwise relate to or result from the failure to meet revenue or earnings predictions prepared by the Company or revenue or earnings predictions of equity analysts or to the receipt of any credit ratings downgrade may be deemed to constitute, or be taken into account in determining whether there has been, or would reasonably be expected to be, a Company Material Adverse Effect); (D) changes in laws, rules or regulations of any Governmental Entity affecting the energy market as a whole except to the extent the Company and its Subsidiaries, taken as a whole, are materially and adversely affected in a disproportionate manner as compared to comparable participants in the energy market; (E) any orders or decisions by the Washington Utilities and Transportation Commission (the “WUTC”) or Oregon Public Utility Commission (the “OPUC”) regarding the Company or the transactions contemplated hereby; (F) any change in generally accepted accounting principles (“GAAP”) by the Financial Accounting Standards Board, the SEC or any other regulatory body; (G) any change in the price of the Company Common Shares (it being understood that the facts or occurrences giving rise or contributing to any such change in the price of the Company Common Shares may be deemed to constitute, or be taken into account in determining whether there has been, or would reasonably be expected to be, a Company Material Adverse Effect); (H) any outbreak or escalation of hostilities, terrorism or war (whether or not declared), or the declaration by the United States of a national emergency or war or the occurrence of any other calamity or crisis or natural disaster, in each case that does not directly affect the assets or properties of, or communities served by, the Company and its Subsidiaries, taken as a whole; (I) the effects of weather or other meteorological events; or (J) the compliance of any party hereto with the terms of this Agreement.

Section 3.2 Subsidiaries.

No Subsidiary of the Company is a Significant Subsidiary. “Significant Subsidiary” of any Person means a Subsidiary of such Person that would constitute a “significant subsidiary” of such Person within the meaning of Rule 1.02(w) of Regulation S-X as promulgated by the SEC.

(b) All of the outstanding Capital Stock of each Subsidiary of the Company is owned by the Company, by one or more Subsidiaries of the Company or by the Company and one or more Subsidiaries of the Company. Except for the Capital Stock of its Subsidiaries, the Company does not own, directly or indirectly, any Capital Stock of any corporation, partnership, joint venture, limited liability company or other entity. Neither the Company nor any of its Subsidiaries is a party to, or has any commitment to become a party to, any joint venture, off-balance sheet partnership or any similar written or oral agreement, undertaking, contract, commitment, lease, license, permit, franchise, concession, deed of trust, contract, note, bond, mortgage, indenture, arrangement or other instrument or obligation (“Contract”). “Capital Stock” means, as applicable any capital stock of a corporation or any other equity interest

Section 5.2 No Solicitation.

(a) From the date hereof until the earlier of the Effective Time or the date on which this Agreement is terminated in accordance with the terms hereof, the Company will not, nor will it permit any of its Subsidiaries to, nor will it or its Subsidiaries authorize or permit any of their respective officers, directors, employees, representatives or agents to, directly or indirectly, (i)

Buyer), which is reasonably capable of being completed on the terms proposed (taking into account the ability to deliver any consideration to be paid in connection with such transaction and obtain required regulatory approvals).

(b) Except as contemplated in Section 5.2(a) and otherwise in this Agreement, neither the Board of Directors of the Company nor any committee thereof will (i) withdraw, qualify or modify, in a manner adverse to Buyer, the approval by such Board of Directors of the Merger and this Agreement and the transactions contemplated hereby or the recommendation by such Board of Directors of this Agreement, (ii) approve or recommend, or propose to approve or recommend, any Takeover Proposal or (iii) authorize or permit the Company or any of its Subsidiaries to enter into any Acquisition Agreement.

(d) The Company agrees that it and its Subsidiaries will, and the Company will direct and cause its and its Subsidiaries’ respective officers, directors, employees, representatives and agents to, immediately cease and cause to be terminated any activities, discussions or negotiations with any Persons with respect to any Takeover Proposal. The Company agrees that it will notify Buyer in writing as promptly as practicable (and in any event within two business days) after any Takeover Proposal is received by, any information is requested by any Person who the Board of Directors in good faith believes is reasonably likely to make a Takeover Proposal from, or any discussions or negotiations relating to a Takeover Proposal are sought to be initiated or continued with, the Company, its Subsidiaries, or their officers, directors, employees, representatives or agents. The notice will indicate the name of the Person making such Takeover Proposal or taking such action and the material terms and conditions of any proposals or offers, and thereafter the Company will keep Buyer informed, on a current basis, of the status and materials terms of any such proposals or offers and the status of any such discussions or negotiations.

Section 5.3 Rate and Regulatory Matters. To the extent permitted by applicable law, the Company will cause each of its Subsidiaries to deliver to Buyer a copy of each principal filing or agreement (other than filings or agreements related to a fuel adjustment or purchase gas adjustment or similar adjusting rate mechanism) related to its generally applicable rates, charges, standards of service, accounting or regulatory policy which could lead to a material change in any of those areas as soon as practicable and in any event no later than five business days prior to the filing or execution thereof so that Buyer may comment thereon.

(c) To the extent permitted by applicable law, the Company will, and will cause its Subsidiaries to, consult with Buyer with respect to negotiations relating to the renewal of any collective bargaining agreement.

(d) The Company and Buyer each will give prompt notice to the other of any proposed change that is reasonably likely to result in a Company Material Adverse Effect and Buyer Adverse Effect, respectively.

Buyer will have received a certificate signed on behalf of the Company by the Company’s Chief Executive Officer and Chief Financial Officer to such effect.

(b) Performance of Obligations. The Company will have performed in all material respects all obligations and complied in all material respects with all agreements and covenants of the Company to be performed and complied with by it under this Agreement at or prior to the Effective Time.

(c) Material Adverse Effect. From the date hereof through the Effective Date, there will not have been any event, effect, change or development that, individually or in the aggregate with other such events, effects, changes or developments, has had, or would reasonably be expected to have, a Company Material Adverse Effect.

(d) Consents Under Agreements. The Company will have obtained the consent or approval of each Person whose consent or approval will be required under any Contract to which the Company or any of its Subsidiaries is a party, except those to be obtained pursuant to Section 7.1(c), and those for which the failure to obtain such consent or approval would not, individually or in the aggregate, have a Company Material Adverse Effect or, after giving effect to the Merger, a material adverse effect on Buyer.

(e) FIRPTA. Prior to the Closing on the Closing Date, the Company shall cause to be delivered to Buyer an executed affidavit, in accordance with Treasury Regulation Section 1.897-2(h)(2), certifying that an interest in the Company is not a U.S. real property interest within the meaning of Section 897(c) of the Code and sets forth the Company’s name, address and taxpayer identification number.

ARTICLE VIII
TERMINATION

Section 8.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after the Company Shareholder Approval (the date of any such termination, the “Termination Date”):

(a) by mutual written consent of Buyer and the Company;

(b) by either Buyer or the Company if (i) any Government Authority of competent jurisdiction has issued a Final Order denying the grant of a Required Buyer Statutory Approval

or a Company Required Statutory Approval, in each case as a result of which the condition set forth in Section 7.1(c) cannot be satisfied, or (ii) any Governmental Entity will have enacted, issued, promulgated or entered any statute, law, ordinance, regulation, judgment, injunction, order, decree or ruling or taken any other action which is a Final Order permanently enjoining, restraining or otherwise prohibiting the transactions contemplated by this Agreement; provided, that the party seeking to terminate this Agreement under this Section 8.1(b) shall otherwise have performed or observed the covenants and agreements of such party set forth herein;

(c) by Buyer if there has been a breach of any representation, warranty, covenant or other agreement made by the Company in this Agreement, or any such representation and warranty will have become untrue after the date of this Agreement, in each case such that Section 7.3(a) or Section 7.3(b) would not be satisfied, and such breach or condition is not curable or, if curable, is not cured within 60 days after written notice thereof is given by Buyer to the Company;

(d) by Buyer if (i) the Company’s Board of Directors has not recommended, or has withdrawn or qualified or modified in any manner adverse to Buyer its recommendation of, this Agreement or the Merger, (ii) the Company’s Board of Directors (or any committee thereof) has entered into a definitive agreement for or recommended any Takeover Proposal, (iii) the Company has breached Section 5.2 in any material respect or (iv) a tender offer or exchange offer for 50% or more of the outstanding shares of Capital Stock of the Company is commenced, and the Company’s Board of Directors fails to recommend against acceptance of such tender offer or exchange offer by its shareholders within ten days after such commencement (including by taking no position with respect to the acceptance of such tender offer or exchange offer by its shareholders);

(e) by the Company prior to obtaining the Company Shareholder Approval if (i) the Board of Directors of the Company authorizes the Company, subject to complying with the terms of this Agreement, to enter into a definitive agreement concerning a transaction that constitutes a Superior Proposal and the Company notifies Buyer in writing that it intends to enter into such an agreement, attaching the most current version of such agreement to such notice, (ii) Buyer does not make, within five business days of receipt of the Company’s written notification of its intention to enter into a definitive agreement for a Superior Proposal, an offer that the Board of Directors of the Company determines, in its reasonable good faith judgment after consultation with its financial and other advisors, is at least as favorable (taking into account (A) all financial and strategic considerations, including relevant legal, financial, regulatory and other aspects of such Takeover Proposal and the Merger and the other transactions contemplated by this Agreement deemed relevant by the Board of Directors, (B) the identity of the third party making such Takeover Proposal and (C) the conditions and prospects for completion of such Takeover Proposal) to the shareholders of the Company as the Superior Proposal and (iii) the Company prior to or concurrently with such termination pays to Buyer in immediately available funds the amount required by Section 8.2(b). The Company agrees (1) that it will not enter into a definitive agreement referred to in clause (i) above until at least the sixth business day after it has provided the notice to Buyer required thereby and (2) to notify Buyer promptly in writing if its intention to enter into a definitive agreement referred to in its notification changes at any time after giving such notification;

(f) by the Company if there has been a breach of any representation, warranty, covenant or other agreement made by Buyer in this Agreement, or any such representation and warranty will have become untrue after the date of this Agreement, in each case such that Section 7.2(a) or Section 7.2(b) would not be satisfied, and such breach or condition is not curable or, if curable, is not cured within 60 days after written notice thereof is given by the Company to Buyer;

(g) by either the Company or Buyer if at the Company Shareholders Meeting (including any adjournment or postponement thereof), the Company Shareholder Approval is not obtained; or

(h) by either Buyer or the Company if the Merger has not been consummated by the date which is nine months after the date of this Agreement (the “End Date”); provided, however, that if all other conditions set forth in Article VII (other than conditions that by their nature are to be satisfied on the Closing Date) are satisfied except that the WUTC Approval and the OPUC Approval have not been obtained, either Buyer or the Company, by written notice delivered to the other party prior to the End Date, may extend such period by six months after the End Date; provided, further, that the right to terminate this Agreement under this Section 8.1(i) will not be available to any party whose failure to fulfill any obligation under this Agreement has been the cause of or resulted in the failure of the Merger to occur on or before the End Date.

Section 8.2 Effect of Termination.

(a) In the event of a termination of this Agreement by either the Company or Buyer as provided in Section 8.1, this Agreement will forthwith become void and there will be no liability or obligation on the part of Buyer or the Company or their respective officers or directors, except with respect to Section 3.22, Section 4.10, Section 6.4, this Section 8.2 and Article IX; provided, however, that nothing herein will relieve any party for liability for any willful or knowing breach hereof.

(b) If this Agreement is terminated by Buyer pursuant to Section 8.1(c), then the rights of Buyer to pursue all legal remedies available will survive such termination unimpaired and no election of remedies will be deemed to be made, and further, if (i) at or prior to the Termination Date a Takeover Proposal shall have been publicly announced, commenced or otherwise communicated or made known to the Company’s Board of Directors (or any person shall have publicly announced, commenced or otherwise communicated or made known an intention to the Company’s Board of Directors, whether or not conditional, to make a Takeover Proposal) and (ii) within 12 months after the Termination Date, the Company or any of its Subsidiaries either becomes a party to any definitive, binding agreement with respect to a Takeover Proposal (which need not be the same Takeover Proposal described in clause (i)) or consummates a transaction that would constitute a Takeover Proposal (which need not be the same Takeover Proposal described in clause (i)), then, in either case, the Company will pay to Buyer an amount equal to the Termination Fee.

(c) If this Agreement is terminated (i) by Buyer pursuant to Section 8.1(d) or (ii) by the Company pursuant to Section 8.1(e), then the Company will pay to Buyer, an amount equal to the Termination Fee.

(d) If this Agreement is terminated by the Company pursuant to Section 8.1(f), the rights of the Company to pursue all legal remedies available will survive such termination unimpaired and no election of remedies will be deemed to have been made.

(e) If this Agreement is terminated by either the Company or Buyer pursuant to Section 8.1(b), Section 8.1(g) (other than a termination of this Agreement by reason of the issuance of a Final Order by the North Dakota Public Service Commission or the Minnesota Public Utilities Commission denying the grant of a Buyer Required Statutory Approval) or Section 8.1(h), and (i) at or prior to the Termination Date a Takeover Proposal shall have been publicly announced, commenced or otherwise communicated or made known to an executive officer or the Board of Directors of the Company (or any person shall have publicly announced, commenced or otherwise communicated or made known an intention to an executive officer or the Board of Directors of the Company, whether or not conditional, to make a Takeover Proposal) and (ii) within twelve months after the binding Termination Date, the Company or any of its Subsidiaries either became a party to any definitive, binding agreement, with respect to a Takeover Proposal (which need not be the same Takeover Proposal described in clause (i)) or consummates a transaction that would constitute a Takeover Proposal (which need not be the same Takeover Proposal described in clause (i)), then, in either case, the Company will pay to Buyer an amount equal to the Termination Fee.

(f) The Company shall pay the Termination Fee to Buyer by wire transfer of immediately available funds within two business days after the date giving rise to the obligations to make such payment.

(g) As used in this Agreement, “Termination Fee” shall mean $9,000,000.

(h) The Company and Buyer acknowledge that the agreements contained in Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Buyer or the Company, as applicable, would not enter into this Agreement. If the Company fails to promptly pay the amount due pursuant to this Section 8.2 and, in order to obtain such payment, Buyer commences a suit which results in a judgment against the Company for any of the amounts set forth in this Section 8.2, the Company will pay to Buyer, its costs and expenses (including attorneys’ fees) in connection with such suit.

(i) Neither the Company nor Buyer, as the case may be, may terminate this Agreement, and receive any applicable fees pursuant to this Section 8.2, under more than one subsection of Section 8.1.

ARTICLE IX

For the purposes of this Agreement, delivery or transmission of (A) a writing, a copy of a writing, or a physical reproduction, on paper or on other tangible material, or (B) an email, in each case pursuant to this Section 9.2, constitutes delivery “in writing.”

Section 9.3 Counterparts. This Agreement may be executed in counterparts, all of which will be considered one and the same agreement, and will become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties, it being understood that all parties need not sign the same counterpart.

Section 9.4 Entire Agreement; No Third-Party Beneficiaries. Except for the Confidentiality Agreement and all documents contemplated herein to be executed and/or delivered at or in connection with the Merger, this Agreement (and the schedules and exhibits hereto) constitute the entire agreement and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof. This Agreement, except for the provisions of Section 6.8, is not intended to confer upon any Person other than the parties hereto any rights or remedies hereunder.

Section 9.5 Governing Law and Venue; Waiver of Jury Trial. (a) THIS AGREEMENT WILL BE DEEMED TO BE MADE IN AND IN ALL RESPECTS WILL BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN ACCORDANCE WITH THE LAW OF THE STATE OF WASHINGTON WITHOUT GIVING EFFECT TO THE CONFLICT OF LAW PRINCIPLES THEREOF THAT WOULD REQUIRE THE APPLICATION OF THE LAW OF ANOTHER JURISDICTION. Each of the parties irrevocably submits to the exclusive jurisdiction of any state or federal court sitting in the State of Washington for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby. Each of the parties hereto irrevocably and fully waives the defense of an inconvenient forum to the maintenance of such suit, action or

proceeding. Each of the parties hereto irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in any state or federal court sitting in the State of Washington, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

(b) EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION, SUITE OR PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT.

Section 9.6 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder may be assigned by any of the parties hereto (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.

Section 9.7 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement will nevertheless remain in full force and effect so long as the economic and legal substance of the transactions contemplated hereby are not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced by any rule of law or public policy, the parties will negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement may be consummated as originally contemplated to the fullest extent possible.

Section 9.8 Enforcement of this Agreement. In addition to any remedy to which any party hereto is specifically entitled by the terms hereof, each party will be entitled to pursue any other remedy available to it at law or in equity (including damages, specific performance or other injunctive relief) in the event that any of the provisions of this Agreement were not performed in accordance with their terms or were otherwise breached; provided that, notwithstanding the foregoing, if a termination fee or any expenses in connection with the transactions contemplated by this Agreement are payable pursuant to Section 8.2, then, subject to Section 8.2(a), such termination fee or expenses will be the sole remedy with respect to the failure or failures to perform or other breach or breaches giving rise to such obligation to pay such termination fee or expenses. The parties hereto agree that (a) irreparable damage would occur and that the parties hereto would not have an adequate remedy at law if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached and (b) they will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically this Agreement in any court having jurisdiction over the parties and the matter, subject to Section 9.5, in addition to any other remedy to which they may be entitled at law or in equity.

Section 9.9 Obligations of Subsidiaries. Whenever this Agreement requires any Subsidiary of Buyer or of the Company to take any action, such requirement will be deemed to include an undertaking on the part of Buyer or the Company, as the case may be, to cause such Subsidiary to take such action.

Section 9.10 Amendment. This Agreement may be amended by the parties hereto at any time before or after obtaining the Company Shareholder Approval, but if the Company Shareholder Approval has been obtained, thereafter no amendment will be made which by law requires further approval by the Company’s shareholders without obtaining such further approval. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

Section 9.11 Extension; Waiver. At any time prior to the Effective Time, the parties hereto, by action taken or authorized by their respective Board of Directors, may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (ii) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto or (iii) waive compliance with any of the agreements or conditions contained herein; provided, however, that such extension or waiver will not operate as a waiver of, or estoppel with respect to, any subsequent or other failure. Any agreement on the part of a party hereto to any such extension or waiver will be valid only if set forth in a written instrument signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise will not constitute a waiver of those rights.

Section 9.12 Disclosure Schedules. The disclosures made on the Company Disclosure Schedules and the Buyer Disclosure Schedules, with respect to any representation or warranty hereunder, will be deemed to be made with respect to any other representation or warranty requiring the same or similar disclosure to the extent that the relevance of such disclosure to other representations and warranties is reasonably evident from the face of such disclosure. The inclusion of any matter on the Company Disclosure Schedules and the Buyer Disclosure Schedules will not be deemed an admission by any party that such matter is material or that such matter has or could reasonably be expected to have a Material Adverse Effect with respect to the Company or Buyer, as applicable.

Section 9.13 Construction. The table of contents, index of defined terms and headings contained in this Agreement are for reference purposes only and will not affect in any way the meaning or interpretation of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they will be deemed to be followed by the words “without limitation.” Words in the singular form will be construed to include the plural and vice versa, unless the context requires otherwise. Any reference to the Surviving Corporation or to the Company after giving effect to the Merger means Buyer as the Surviving Corporation.
