Prior to the Closing Date, (i) the Sellers other than PacifiCorp shall convey their interests in the facilities described in Section 2.2(a) to PacifiCorp pursuant to a separate purchase and sale agreement and (ii) PacifiCorp, the Buyer and the "Buyer" under the Centralia Coal Mine Purchase and Sale Agreement of even date herewith, or their Affiliates, shall enter into one or more contracts pursuant to which (A) PacifiCorp provides transmission services necessary to deliver certain electric power requirements of the Plant and the Centralia Coal Mine from the 230 kV facilities of the Bonneville Power Administration to the Plant and the Centralia Coal Mine and (B) such parties address access, maintenance and other matters with respect to these retained facilities. These agreements shall be collectively referred to as the "Transmission Arrangements."

     Section 2.6  Purchase Price. The total purchase price for the LLC Interests shall be the sum of the Plant Purchase Price, the Supplies Purchase Price, the Coal Inventory Purchase Price and the RACT Compliance Costs as each amount is defined in this Section 2.6.

              (a)  Plant Purchase Price. The "Plant Purchase Price" shall be U.S. $452,598,000, subject to such adjustments, if any, as may occur pursuant to this Section 2.6 and other provisions of this Agreement. Buyer shall, or shall cause one or more Buyer Subsidiaries to, pay to Sellers the Plant Purchase Price in cash at the Closing by wire transfer of immediately available funds in U.S. dollars to an account specified in writing by Sellers to Buyer not later than the second Business Day prior to the Closing Date.

              (b)  Supplies Purchase Price and Coal Inventories Purchase Price. The "Supplies Purchase Price" shall equal Sellers' original cost basis in the Supplies as of the Closing Date. The"Coal Inventory Purchase Price" shall equal the product of the number of tons of coal constituting the Coal Inventory on the Closing Date and the average per ton price (F.O.B. Centralia) of the last 100,000 tons of coal delivered to the Plant by rail prior to the Closing Date; provided however; in respect to coal in the Coal Inventory which was delivered from the Centralia Mine, the per ton purchase price shall be multiplied by a fraction whose numerator is the average heating value of coal in the Coal Inventory that was delivered from the Centralia Mine and whose denominator is the average heating value of coal in the Coal Inventory delivered to the Plant by rail. Consistent with Section 6.3, Sellers agree not to alter their customary practices for coal procurement in effect prior to the date hereof with respect to coal deliveries that form the basis of such price adjustment. PacifiCorp shall notify Buyer of the amount of the Supplies Purchase Price and the Coal Inventory Purchase Price and deliver supporting workpapers to Buyer within 45 days following the Closing Date. Buyer shall, or shall cause one or more Buyer Subsidiaries to, pay to Sellers the Supplies Purchase Price and the Coal Inventory Purchase Price in cash (U.S.$) within 15 days of such notification by wire transfer of immediately available funds to the same account to which the Plant Purchase Price was paid.

Page 15 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

              (c)  RACT Compliance Costs. In addition to the Plant Purchase Price, Buyer shall reimburse Sellers for costs expended between the date of this Agreement and the Closing Date in connection with RACT Compliance, as such costs are described in Section 2.9. Costs reimbursed by Buyer pursuant to this Section 2.6(c) shall not include PacifiCorp's internal costs to the extent they are charged or accounted for in a manner that is inconsistent with the manner in which PacifiCorp has typically charged and accounted for its internal costs associated with the Plant that are partially reimbursed to PacifiCorp in its role as Plant Operator by the Sellers other than PacifiCorp. PacifiCorp shall notify Buyer of the amount of such costs and deliver supporting work papers to Buyer within 45 days following the Closing Date. Buyer shall pay or cause one or more Buyer subsidiaries to pay to Sellers the amount of such RACT Compliance costs in cash (U.S.$) within 15 days of such notification by wire transfer of immediately available funds to the same account which the Plant Purchase Price was paid.

              (d)  Reduction to Reflect Reclamation Accruals. The Plant Purchase Price shall be reduced by an amount equal to the amount that has been accrued by or on behalf of Sellers for reclamation costs at the Centralia Coal Mine as of the Closing Date in the form of liabilities on PacifiCorp's balance sheet and balances held in separate trust accounts by some Sellers. As of the date of this Agreement, Sellers have estimated this amount to be approximately $54,000,000. The parties shall determine this amount based on a final accounting as of the Closing Date,

              (e)  Plant Purchase Price Allocation. No later than ten Business Days prior to the Closing, Buyer and the Sellers Group shall use their reasonable good faith efforts to reach agreement upon the manner in which the Plant Purchase Price is to be allocated among the Assets in accordance with the Internal Revenue Code. Upon any such agreement being reached, the agreed allocation shall be set forth in a schedule (the "Allocation Schedule") to be attached to this Agreement as Schedule 2.6. Sellers and Buyer shall allocate the Plant Purchase Price in accordance with the Allocation Schedule and shall be bound by such allocations for all purposes, shall account for and report the purchases and sales contemplated hereby for all purposes (including, without limitation, financial, accounting, and federal and state tax purposes) in accordance with such allocations, and shall not take any position (whether in financial statements, tax returns, or tax audits, or otherwise), which is inconsistent with such allocations without the prior written consent of the other party, except to the extent, if any, required by applicable Law or generally accepted accounting principles. In the event that Buyer and the Sellers Group do not agree on an allocation of the Plant Purchase Price pursuant to this Section, then the Plant Purchase Price shall be allocated among the Assets in proportion to Sellers' net book value therefor .

              (f)  Certain Post-Closing Adjustments. The Plant Purchase Price shall be subject to the following post-Closing adjustments, but only if such adjustments, in the aggregate, will result in a change in the Plant Purchase Price of $250,000 or more:

Page 16 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

                   (i)     The Plant Purchase Price shall be increased by the amount
     expended by Sellers between the date hereof and the Closing Date for capital additions
     to or replacements of property, plant and equipment included in the Assets and other
     expenditures or repairs on property, plant and equipment included in the Assets that
     would be capitalized by Sellers in accordance with their normal capitalization policies
     (together "Capital Expenditures"), which Capital Expenditures either appear on
     Schedule 2.6(f)(i) or, subject to the provisions of Section 6.3(f), are otherwise deemed
     reasonably necessary by Sellers for the continued operation or maintenance of the Plant
     and the Assets or for compliance with Law, provided that such Capital Expenditures
     shall not include Remediation Measures in respect of Existing Soils Contamination or
     spare parts, materials and supplies which constitute Supplies, Coal Inventories, or costs
     of RACT Compliance.

                   (ii)    In order to implement the foregoing, PacifiCorp shall cause to be
     prepared and shall provide Buyer, as soon as possible after the Closing Date and in no
     event later than 60 days thereafter, with a schedule setting forth Sellers' Capital
     Expenditures between the date hereof and the Closing Date in reasonable detail so as to
     permit Buyer to be able to determine the extent to which such Capital Expenditures are
     or are not listed on Schedule 2.6(f)(i).

Any adjustments to the Plant Purchase Price shall be consistent with the Allocation Schedule (if such schedule has been previously agreed to).

     Section 2.7  License of Non-Transferred Intangible Assets. Although trade names of Sellers are Excluded Assets, such names appear on certain of the Assets, such as certain fixtures and Equipment, and on supplies, materials, stationery and similar consumable items which will be on hand at the Plant at the Closing. Notwithstanding that such names are Excluded Assets, the LLC, Buyer and the Buyer Subsidiaries shall be entitled to use such consumable items for a period of three months following the Closing and shall have up to six months following the Closing to remove such names from fixed Assets, provided that none of such parties shall send correspondence or other materials to third parties on any stationery that contains a trade name or trademark of Sellers or any Affiliates of Sellers. Sellers hereby grant to the LLC and Buyer the irrevocable, fully paid-up, royalty-free, nontransferable, non-exclusive right and license to use, solely in connection with the operation of the Plant, such proprietary computer software of Sellers located at the Plant that is presently used at the Plant's location exclusively in connection with the operation of such Plant and that is an Excluded Asset under Section 2.2(d) or (k), except for such computer software that is designed to be part of a networked computer system providing data processing capabilities or services beyond the Plant in question and provided that in no event shall the LLC or Buyer or any successor have access under such license to Sellers' own computer networks. The licenses contained in this Section 2.7 may, at the Sellers' option, be made the subject of a separate

Page 17 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

agreement between the parties, in which case the parties shall negotiate the terms thereof in good faith.

     Section 2.8  Assignment of Rights and Obligations to Buyer Subsidiaries. For purposes of this Agreement, the term "Buyer Subsidiary" shall refer to any direct or indirect subsidiary of Buyer and any constituent partner or participant in Buyer (if Buyer is a partnership, joint venture, consortium or other association or organization) to which any of Buyer's rights and obligations hereunder are assigned in compliance with the requirements of this Section. Notwithstanding any contrary provisions contained herein, the parties hereto agree that, prior to and after the Closing, Buyer, in its sole discretion, may assign any or all of its rights and obligations arising under this Agreement, any Related Agreement or any other agreement contemplated hereby to one or more Buyer Subsidiaries, provided that no such assignment shall relieve Buyer of any obligation or liability to Sellers hereunder or under any Related Agreement or any other agreement contemplated hereby, and provided further that the following shall apply:

              (a)  Buyer will provide Sellers with prior written notice of any such assignment.

              (b)  No such assignment shall be effective if the making of the assignment will result in Sellers' or Buyer's inability to obtain any consent or authorization reasonably required to consummate the transactions contemplated hereby or to avoid economic detriment to Sellers arising from the consummation of such transactions.

              (c)  Each such Buyer Subsidiary that is an assignee of Buyer shall irrevocably appoint Buyer as an authorized representative and agent authorized to act for, to bind and to receive notices and payments on behalf of the Buyer Subsidiaries in all matters arising from or related to this Agreement and the transactions contemplated hereby.

              (d)  Irrespective of any such assignment or the identity of the party or parties executing any Related Agreements or any other agreement contemplated hereby:

                   (i)     Buyer shall remain jointly and severally liable with each
     Buyer Subsidiary to Sellers and to third parties with respect to any Assumed
     Liabilities transferred to or undertaken by a Buyer Subsidiary, and shall remain
     jointly and severally liable with each Buyer Subsidiary to Sellers with respect to
     any other covenant, obligation or liability to Sellers hereunder or under any
     Related Agreement or any other agreement contemplated hereby that is
     transferred to, or undertaken by, a Buyer Subsidiary, including without
     limitation, the payment of all sums due to Sellers hereunder or under any
     Related Agreement or any other agreement contemplated hereby, it being
     understood that all such covenants, obligations and liabilities shall constitute the

Page 18 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

     direct and primary obligation of Buyer to Sellers (and to third parties in the case
     of the Assumed Liabilities); and

                   (ii)    Without limiting the generality of the foregoing, if and to
     the extent that the application of any principle of Law would construe the
     retention by Buyer of the direct and primary obligation to perform any and all
     obligations, liabilities or covenants assigned to or assumed or undertaken by a
     Buyer Subsidiary to be a guaranty by Buyer of the Buyer Subsidiary's
     performance, then Buyer hereby irrevocably, absolutely and unconditionally
     guarantees to Sellers the full, prompt and faithful performance by such Buyer
     Subsidiary of all covenants and obligations to be performed by such Buyer
     Subsidiary under this Agreement and any Related Agreement or any other
     agreement contemplated hereby assigned to such Buyer Subsidiary.

              (e)  Buyer further hereby agrees that a separate action or actions may be brought and prosecuted against Buyer for any such covenant, obligation or liability assigned to a Buyer Subsidiary, whether action is brought against the pertinent Buyer Subsidiary or whether such Buyer Subsidiary is joined in any such action or actions (Buyer hereby waiving any right to require Sellers to proceed against a Buyer Subsidiary).

              (f)  Buyer hereby authorizes Sellers, without notice and without affecting Buyer's liability hereunder, from time to time to (i) renew, compromise, extend, accelerate, or otherwise change the terms of any obligations of a Buyer Subsidiary hereunder or under any Related Agreement or any other agreement contemplated hereby with the agreement of such Buyer Subsidiary, (ii) take and hold security for the obligations of any such Buyer Subsidiary and exchange, enforce, waive and release any such security, and (iii) apply such security and direct the order or manner of sale thereof as Sellers in its discretion may determine.

              (g)  Buyer hereby further waives:

                   (i)     Any defense that may arise by reason of the incapacity or
     lack of authority of any Buyer Subsidiary;

                   (ii)    Any defense based upon any Law or legal or equitable
     principle which provides that the obligations of a surety must be neither larger
     in amount nor in other respects more burdensome than those of the principal;

                   (iii)   Any duty on the part of Sellers to disclose to Buyer any
     facts that Sellers may now or hereafter know about a Buyer Subsidiary; and

                   (iv)    Any right to subrogation, reimbursement, exoneration or
     contribution or any other rights that would result in Buyer being deemed a

Page 19 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

     creditor of a Buyer Subsidiary under the federal Bankruptcy Code or any other
     Law, in each case arising from the existence or performance by Buyer of any
     obligation of a Buyer Subsidiary hereunder or under any Related Agreement or
     any other agreement contemplated hereby.

     Section 2.9  RACT Compliance. Buyer is aware that commencing in August 1995, the Southwest Washington Air Pollution Control Agency issued and reissued a series of "RACT" Orders pertaining to the Plant. The last such RACT Order was issued in February 1998, and provided for an annual limit of 10,000 tons of sulphur dioxide emissions and specified additional limits on nitrogen dioxide emissions. In order to comply with this RACT Order the Sellers have determined to initiate the actions necessary to install a flue gas desulferization system ("Scrubbers") and certain nitrogen dioxide control equipment ("Burners"). For purposes of this Agreement, the installation of the Scrubbers and the Burners as a means of timely complying with the RACT Order shall be referred to as "RACT Compliance." Upon the Closing, Buyer shall assume project management responsibility for RACT Compliance. Costs of RACT Compliance are estimated by PacifiCorp to be approximately $190,000,000, consisting of payments pursuant to a turn-key contract for installation of the Scrubbers; payments pursuant to a turn-key contract for the installation of the Burners; PacifiCorp's internal costs associated with project management, engineering and support and capitalized interest ("RACT Compliance Costs"). The cost of the Burners is estimated by PacifiCorp to be approximately $17,000,000.

     Section 2.10  Scrubbers. No later than May 31, 1999, PacifiCorp on behalf of itself and the other Sellers shall use its best efforts to negotiate and execute a turn-key contract for Scrubber installation in substantially the form set out in Schedule 2.10 (the "Scrubber Contract") including terms and conditions no less favorable than those contained in the ABB Flakt, Inc. and Stone & Webster Corporation proposal dated April 1, 1999. Absent the written consent of Buyer, Sellers shall maintain the Scrubber Contract in full force and effect without any material breach by the Sellers. At the Closing, the Scrubber Contract shall be assigned by the Sellers and assumed by the LLC and Buyer. If, notwithstanding its best efforts, PacifiCorp is not able to timely enter into the Scrubber Contract or the "target price," "target price contingency amount" (as those terms are defined in the Scrubber Contract) or completion date are different than those provided for in the Scrubber Contract, the Sellers Group must elect, within 30 days of such occurrence, to either: (i) terminate this Agreement or (ii) agree to make the LLC and Buyer economically whole in regard to such difference and/or pay the amount of any such increased price and/or the amount of any fines or civil penalties that are incurred by the LLC and Buyer as a result of not adhering to the milestone associated with a scrubber contract contained in the RACT Order.

     Section 2.11  Escrow. At the Closing, Sellers shall deposit $6,000,000 in an escrow account held by an escrow agent identified by Buyer and acceptable to Sellers. To the extent that total costs ultimately paid pursuant to the Scrubber Contract for activities within the scope

Page 20 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

of the Scrubber Contract executed in accordance with Section 2.10 exceed $150,600,000, 50 percent of such exceedance shall be paid from the escrow account to Buyer and the balance remaining in the escrow account (if any) upon completion or termination of such Scrubber Contract shall be paid over to PacifiCorp on behalf of itself and the other Sellers. Except as provided for herein, Sellers shall have no liability or obligation for the payment of costs of RACT Compliance incurred subsequent to the Closing Date.

     Section 2.12  Burners. If the Closing Date has not previously occurred, no later than January 1, 2000, PacifiCorp on behalf of itself and the other Sellers, shall use its best efforts to negotiate and enter into a turn-key contract for the installation of the Burners ("Burner Contract") on terms reasonably acceptable to Buyer and Sellers other than PacifiCorp. The Burner Contract shall provide that it is freely assignable to the LLC and Buyer and it shall be assigned by the Sellers and assumed by the LLC and Buyer at the Closing. Prior to the Closing Date, absent the written consent of Buyer, Sellers shall maintain the Burner Contract in full force and effect without any material breach by the Sellers.

     Sellers hereby represent and warrant to Buyer, as of the date hereof, as follows, except as set forth in Schedules numbered in relation to the Sections set forth below:

     Section 3.1  Authority and Enforceability. The execution, delivery and performance of this Agreement, the Related Agreements and all other agreements contemplated hereby and the consummation of the transactions contemplated hereby and thereby have been duly authorized by the board of directors or other applicable governing body of each Seller; no other corporate act or proceeding on the part of any Seller is necessary to authorize this Agreement or any Related Agreement or any other agreement contemplated hereby or the transactions contemplated thereby. This Agreement has been, and each of the Related Agreements and other agreements contemplated hereby will, as of the Closing, have been, duly executed and delivered by each of Sellers, and this Agreement constitutes, and each Related Agreements and such other agreements when executed and delivered will constitute, a valid and binding obligation of Sellers, enforceable against Sellers in accordance with its terms, except as it may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar Laws now or hereafter in affect relating to creditors' rights generally and that the remedy of specific performance and injunctive and other forms of equitable relief may be subject to equitable defenses and to the discretion of the court before which any proceeding may be brought.

     Section 3.4  Permits. Except as set forth in Schedule 3.4, at the date hereof to Sellers' Knowledge, Sellers possess all Licenses necessary for their operation of the Plant at the locations and in the manner presently operated, other than those the absence of which would not have a Material Adverse Effect on the LLC Interests or the Assets.

     Section 3.5  Compliance with Law. Except as set forth in Schedule 3.5, and except for the matters that are the subject of Sections 3.4 and 3.6 and the Schedules, if any, related thereto, to Sellers' Knowledge, Sellers are in compliance in all material respects with all pertinent Laws and Licenses related to the ownership and operation of the LLC Interests or the Assets, other than violations that would not, individually or in the aggregate, have a Material Adverse Effect on the ownership, use or operation of the LLC Interests or the Assets or on the ability of Sellers to execute and deliver this Agreement, the Related Agreements or any other agreements contemplated hereby and consummate the transactions contemplated hereby and thereby.

     Section 3.6  Hazardous Materials. To Sellers' Knowledge, except as disclosed by the "Phase I" and Phase II" environmental site assessments prepared by Sellers' outside environmental consultants and made available for inspection by Buyer, or as otherwise disclosed on Schedule 3.6:

              (a)  There has not been a Release of Hazardous Material on or otherwise affecting the Assets (other than Releases involving de minimis quantities of Hazardous Materials) that: (i) constitutes an unremedied material violation of any Environmental Law by Sellers or by any third party if the effect of such violation by such third party imposes a current remediation obligation on the part of Sellers; (ii)  currently imposes any material release-reporting obligations on Sellers under any Environmental Law that have not been or are not being complied with; or (iii) currently imposes any material clean-up or remediation obligations of Sellers under any Environmental Law.

     Section 3.8  Independent Engineer Report. Sellers have reviewed the report, dated July 22, 1998, (the "Independent Engineer Report") of the independent engineers retained to assist the bidders in the Auction in their respective evaluations of the Assets, and while Sellers have not independently verified the information and data contained therein, to Sellers' Knowledge, except as may be set forth in Schedule 3.8, there is no misstatement of facts contained in the sections of the Independent Engineer Report specified in Schedule 3.8, other than matters which individually or in the aggregate do not have a Material Adverse Effect on the Assets.

As of the Closing Date, Sellers will have good, valid and marketable title to all such real property free and clear of all liens, mortgages, deed restrictions, charges, claims, pledges, security interests, equities and encumbrances that could materially affect the value of such real property or the use of such real property in connection with the ownership and operation of the Plant.

     Section 3.16  Year 2000 Readiness. PacifiCorp hereby represents and warrants to Buyer that except as delineated on Schedule 3.16, all of the hardware, software and firmware

Page 26 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

product (including embedded microcontrollers in non-computer equipment) which are included in the Assets (the "Computer Systems") are (and will remain) Year 2000 Ready and will reliably operate the Assets into the Year 2000, and that Computer Systems delineated on Schedule 3.16 are either not necessary for the reliable operation of the Assets into the Year 2000 or will be made Year 2000 Ready prior to January 1, 2000. For purposes hereof, "Year 2000 Ready" shall mean a Computer System or component thereof that has been determined to be suitable for continued use into the Year 2000, but is not necessarily Year 2000 compliant, which implies fully correct date manipulations. PacifiCorp has developed and will maintain and implement a plan to achieve Year 2000 Readiness using standard industry practices and shall consult and cooperate with the Buyer regarding such implementation during the period prior to the Closing Date.

     Section 3.17  Taxes. Those Sellers which are for-profit corporations hereby warrant to Buyers that such Sellers have filed all returns required to be filed by them with respect to Taxes, and such Sellers have paid all Taxes that have become due, except where such Tax is being contested in good faith by appropriate proceedings. Sellers which are for-profit corporations have complied with all applicable laws, rules and regulations relating to withholding of Taxes and have, within the time and manner prescribed by law, paid over to the proper governmental authorities all amounts so withheld. All tax returns filed by such Sellers are true, correct and complete. None of the Assets is property that is required to be treated as being owned by any other person pursuant to the so-called "safe harbor lease" provision of former Section 168(h) of the Internal Revenue Code of 1954, and none of the Assets is "tax-exempt use" property within the meaning of Section 103(a) of the Internal Revenue Code. Those Sellers which are for-profit corporations are not "foreign persons" as defined in Internal revenue Code Section 1445(f)(3). Schedule 3.17 sets forth the taxing authorities to which notification of any of the transaction contemplated by this Agreement must be made or which require the Buyer to withhold any portion of the Plant Purchase Price. Those Sellers which are for-profit corporations do not have any liability pursuant to Section 6901 of the Internal Revenue Code or otherwise under applicable state or federal law by virtue of the acquisition by it of any of the Assets (or interest or interests therein), and Buyer will not be subject to such liability as a result of any of the transactions contemplated by this Agreement.

     Section 3.18  LLC Interests. The LLC Interests that Sellers will transfer to Buyer at the Closing constitute Sellers' entire interest in the LLC and the Assets.

     Section 3.19  Liability. Prior to the Closing, the LLC has no direct or indirect liability, indebtedness, obligation, commitment, expense, claim, deficiency, liability for Taxes, guaranty or endorsement of any type, whether accrued, absolute, contingent, matured, unmatured, due or to become due or otherwise.

     Section 5.1  Efforts to Close.

              (a)  Reasonable Efforts. Subject to the terms and conditions herein provided including, without limitation, Articles 8 and 9 hereof, each of the parties hereto agrees to take all reasonable actions and to do all reasonable things necessary, proper or advisable under applicable Laws to consummate and make effective, as soon as reasonably practicable, the transactions contemplated hereby, including the satisfaction of all conditions thereto set forth herein and including, without limitation, enforcing the provisions of the Auction Protocol Agreements entered into with those proposing to bid to purchase the Plant. Such action shall also include, without limitation, exerting their reasonable efforts to obtain the consents, authorizations and approvals of all private parties and Governmental Bodies whose consent is reasonably necessary to effectuate the transactions contemplated hereby, and effecting all other necessary registrations and filings, including, without limitation, filings under Laws relating to the transfer, reissuance or otherwise obtaining of necessary Licenses, under the HSR Act and all other necessary filings with any Governmental Bodies. Sellers shall cooperate with Buyer's efforts to obtain the requisite Licenses and regulatory consents, provided Sellers shall not be obligated to incur any liabilities or assume any obligations in connection therewith. Other than Buyer's and Sellers' obligations under Section 5.3, no party shall have any liability to the other parties if, after using its reasonable commercial efforts, it is unable to obtain any consents, authorizations or approvals necessary for such party to consummate the transactions contemplated hereby. As used herein, the terms "reasonable efforts" or "reasonable actions" do not include the provision of any consideration to any third party, the commencement of litigation or the suffering of any economic detriment to a party's ongoing operations for the procurement of any such consent, authorization or approval except for the costs of gathering and supplying data or other information or making any filings, the fees and expenses of counsel and consultants and the customary fees and charges of Governmental Bodies. Sellers shall fully cooperate with Buyer regarding the making of offers of employment to employees whose principal work location is at the Plant and Buyer's hiring of such employees and Sellers shall use reasonable efforts to facilitate the orderly hiring of such employees. Furthermore, Sellers and Buyer shall execute and deliver such other agreements, documents and instruments as are required to be delivered by such party or prior to closing to effectuate the transactions contemplated by this Agreement.

              (b)  Control Over Proceedings. All analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party before any Governmental Body (other than any governing board or other governing body of any of the publicly owned utility Sellers) in connection with the approval of the transactions contemplated hereby shall be subject to the joint approval or disapproval and the joint control of Buyer and the Sellers, it being the intent that the Parties will consult and

Page 31 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

cooperate with one another, and consider in good faith the views of one another, in connection with any such analysis, appearance, presentation, memorandum, brief, argument, opinion and proposal; provided that nothing will prevent a party from responding to a subpoena or other legal process as required by Law or submitting factual information in response to a request therefor. Each Party will promptly provide the other with copies of all written communications from Governmental Bodies relating to the approval or disapproval of the transactions contemplated by the Agreement and the Related Agreements. The Sellers will promptly report to Buyer with respect to matters and events involving Governmental Bodies that could have a Material Adverse Effect on the LLC Interests or the Assets and shall timely provide Buyer with copies of relevant documents and notices. Sellers shall consult and cooperate with Buyer in good faith in regard to such matters and events and incorporate Buyer's suggestions where they deem reasonably appropriate. Provided, however, nothing herein shall limit Buyer's ability to intervene or otherwise participate in regulatory proceedings related to the LLC Interests or the Assets.

     Section 5.2  Post-Closing Cooperation. After the Closing, upon prior reasonable written request, each party shall cooperate with the other parties in furnishing records, information, testimony and other assistance in connection with any inquiries, actions, audits, proceedings or disputes involving any of the parties hereto (other than in connection with disputes between the parties hereto) and based upon contracts, arrangements or acts of Sellers which were in effect or occurred on or prior to Closing and which relate to the LLC Interests or the Assets, including, without limitation, arranging discussions with (and the calling as witness of) officers, directors, employees, agents, and representatives of the LLC, Buyer and Buyer Subsidiaries. The requesting party shall in each instance be responsible for payment of any costs and expenses incurred by any other party in affording such cooperation, including any out-of-pocket expenses incurred by such party to third parties; provided, however, that in no event shall the costs and expenses for which any such requesting party shall be liable include any wages or other benefits paid or provided by any such cooperating party to its officers, directors or employees.

     Section 5.3  Expenses.

Notwithstanding the foregoing:

              (a)  Costs associated with preliminary title reports and title insurance policies shall be borne by Sellers up to the costs that would have been incurred had the title policies been standard coverage policies of title insurance, and the remaining costs, if any, including costs for extended coverage and any endorsements shall be borne by Buyer (except that any costs of surveys that are reasonably required shall be borne by Sellers);

Page 32 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

              (b)  All costs of the "Phase I" and "Phase II" environmental site assessments provided by Sellers to Buyer shall be borne by Sellers, and except as specifically set forth herein, any additional environmental investigations shall be borne by Buyer;

              (c)  Costs associated with the Independent Engineer Report within the scope of its initial engagement shall be borne by Sellers, and additional costs for services requested by Buyer, if any, shall be borne by Buyer;

              (d)  Documentary transfer taxes will be borne by Sellers, and recording costs and charges respecting real property will be borne one-half by Buyer and one-half by Sellers;

              (e)  All fees and charges of Governmental Bodies shall be borne by the party incurring the fee or charge, except that all fees and charges of Governmental Bodies in connection with the transfer, issuance or authorization of any License shall be borne by Buyer; and

              (f)  All liabilities or obligations for Taxes in the nature of sales or use taxes or real estate excise taxes incurred as a result of the contribution of the Assets to the LLC or the sale of the LLC Interests hereunder to Buyer shall be borne by Buyer.

              (g)  Each party will bear its own expenses in preparing regulatory filings (including without limitation its own HSR Act filings) and seeking required consents and approvals.

All such charges and expenses shall be promptly settled between the parties at the Closing or upon termination or expiration of further proceedings under this Agreement, or with respect to such charges and expenses not determined as of such time, as soon thereafter as is reasonably practicable.

     Section 5.4  Employees.

              (a)  Assumption of Collective Bargaining Agreements. PacifiCorp shall assign and the LLC and Buyer shall assume the obligations of the employer to the employees at the Plant under the collective bargaining agreement with IBEW Local 125 (the "Collective Bargaining Agreement").

              (b)  Transferred Employees. Buyer shall, no later than three months following the date of this Agreement, notify Sellers of the names of employees not covered by the Collective Bargaining Agreement whose principal work location is at the Plant to whom Buyer will make offers of employment. Except as provided in this Agreement, such offers shall be on such terms as Buyer shall decide. Sellers shall cooperate with Buyer regarding the making of such offers of employment and shall use reasonable efforts, within the meaning of

Page 33 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

Section 5.1(a), to facilitate the orderly hiring by Buyer of such employees. Employees of Seller with a principal work location at the Plant who accept Buyer's offer and who are not Union Employees ("Transferred Employees") shall commence employment with Buyer on the Closing Date.

              (c)  Nonsolicitation. Except to the extent that refraining from doing so would be inconsistent with the provisions of the Collective Bargaining Agreement, without the prior consent of Buyer, Sellers shall refrain and PacifiCorp, Avista Corporation and Puget Sound Energy, Inc. shall use their best efforts to cause any Affiliate to refrain, from offering or otherwise making available any employment or transfer from the date of this Agreement through the date that is 12 months following the Closing Date to any employee whose principal work location is at the Plant as of the date of this Agreement.

              (d)  Benefits in General. Buyer shall provide the Transferred Employees with Benefit Plans that are comparable, in the aggregate, to the Benefit Plans of PacifiCorp covering them just prior to the Closing Date but are no less favorable than those provided by the Buyer to its similarly situated employees. Such Benefit Plans provided by Buyer shall include, but not be limited to, a defined benefit pension plan and a group health plan that provides medical, dental, and vision coverage. The Transferred Employees and their dependents shall be eligible for immediate participation on the Closing Date in such group health plan of Buyer, with no preexisting condition limitations. Amounts incurred prior to the Closing Date by the Transferred Employees and their dependents toward deductibles and out-of-pocket limits shall be counted by Buyer toward parallel limits under its Benefit Plans. Buyer shall give credit to the Transferred Employees for service with Seller for purposes of eligibility to participate and vesting under Buyer's defined benefit pension plan and any other retirement plans of Buyer and for purposes of benefit accruals under Buyer's paid time-off and other service-based welfare benefit plans. Buyer shall provide post-retirement welfare benefits to Transferred Employees and Union Employees that are comparable to those provided to such employees under Sellers' Benefit Plans.

              (e)  Transition of Pension Benefits. Sellers shall cause the PacifiCorp Retirement Plan to make available to each Transferred Employee and to each Union Employee a lump sum distribution equal to the actuarial equivalent present value of the employee's accrued benefit under the terms of such plan as of the Closing Date. Buyer shall cause its defined benefit pension plan to accept, for a period of 90 days beginning on the Closing Date, a direct rollover of the entire lump sum distribution elected by a Transferred Employee or Union Employee and to provide to each employee making such an election a life annuity benefit that is no less than the life annuity benefit accrued under the PacifiCorp Retirement Plan as of the Closing Date, including any increases in compensation from the Closing Date to the date of the employee's termination of all employment with the controlled group of corporations of which the Buyer is a member. The Purchase Price provided by Section 2.6 has been reduced by U.S. $1,000,000 in the aggregate for this Agreement and the Centralia Coal

Page 34 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

Mine Purchase and Sale Agreement of even date herewith, on account of the obligation described in the preceding sentence. If counsel to Buyer and counsel to Sellers agree there is a material risk that the provisions of this paragraph (e) will prevent Buyer's defined benefit pension plan from qualifying under Section 401(a) of the Internal Revenue Code, the parties shall agree upon an alternative which achieves, in the opinion of an actuarial firm, substantially the same economic result for each party as well as affected employees. Such actuarial firm shall be selected jointly by Buyer and Sellers or, if they cannot agree on such selection, by the actuarial firms selected by each of them.

              (f)  Severance. In the event a Transferred Employee is involuntarily terminated from employment with Buyer within two years after the Closing Date, Buyer shall pay such Transferred Employee a severance benefit equal to an amount based on the employee's compensation level (the "Guideline Severance") plus an additional amount based on the employee's length of service (the "Service-Based Severance). The Guideline Severance shall be determined under the following table based on the employee's annual base salary plus target annual bonus level in effect at the time of termination from employment with Buyer:

The Service-Based Severance shall be one week of base salary for each year of service. For this purpose, year of service means the number of completed 12-month periods between the employee's original date of hire with Seller and the date of employment termination with Buyer.

              (g)  Workers' Compensation and Disability. Seller shall retain the obligation to provide disability and workers compensation benefits with respect to Plant employees who do not become employed by Buyer. Buyer shall provide disability and workers compensation benefits to Transferred Employees and Union Employees. In addition, Buyer shall use reasonable efforts, within the meaning of 5.1(a), to provide return-to-work opportunities for Plant employees for whom Seller retained the obligation to provide disability and workers compensation benefits.

     Sellers hereby additionally covenant, promise and agree as follows:

Page 35 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

     Section 6.1  Access. Provided that Buyer has complied with each and every provision thereof, PacifiCorp, on behalf of the Sellers, shall, in accordance with the terms and subject to the conditions of that certain Auction Protocols Agreement by and among Buyer and Sellers, afford Buyer, and the counsel, accountants and other representative of Buyer, reasonable access, throughout the period from the date hereof to the Closing Date, to the Assets and the managerial and technical personnel associated therewith and all the properties, books, contracts, commitments, and records included in the Assets which Sellers have in their possession or to which they have access in order to facilitate transition planning. Such records shall include, but not be limited to, personnel records with respect to employees whose principal work location is at the Plant. Such access shall be afforded to Buyer after no less than 24 hours' prior written notice, during normal business hours and only in such manner as not to disturb or interfere with the normal operation of Sellers, and may include, without limitation, discussion and access relating to Buyer's engineering of Plant air pollution and other modifications Buyer plans to construct after Closing. In addition, with the reasonable approval of the Sellers Group, during the period prior to the Closing Date, Buyer make modifications to the Assets at Buyer's sole cost and expense in order to reduce the requirement for transition services provided for in Section 6.9. PacifiCorp's covenants under this Section are made with the understanding that Buyer shall use all such information in compliance with all Laws. The foregoing notwithstanding, Buyer acknowledges and agrees that Buyer's access to the books and records of the Assets shall not include access to, and PacifiCorp shall not have any obligation to deliver to Buyer, any information concerning any alleged dispute or any pending litigation, investigation or proceeding involving Sellers or their Affiliates that is protected by or subject to the attorney-client privilege, or the disclosure of which is restricted by an agreement entered into in connection with such dispute, litigation, investigation or proceeding or an order entered by any court.

     Section 6.2  Updating. Sellers shall notify Buyer of any changes or additions to any of Sellers' Schedules to this Agreement with respect to the Assets or Assumed Liabilities related thereto by the delivery of updates thereof, if any, as of a reasonably current date prior to the Closing not later than three Business Days prior to the Closing. No such updates made pursuant to this Section shall be deemed to cure an inaccuracy of any representation or warranty made in this Agreement as of the date hereof, unless Buyer specifically agrees thereto in writing nor shall any such notification be considered to constitute or give rise to a waiver by Buyer of any condition set forth in this Agreement. Without limiting the generality of the foregoing, Sellers shall notify Buyer reasonably promptly of the occurrence of any material casualty, physical damage, destruction or physical loss respecting, or, to Sellers' Knowledge, material adverse change in the physical condition of, the Plant, not including ordinary wear and tear and routine maintenance.

     Section 6.3  Conduct Pending Closing. Prior to consummation of the transactions contemplated hereby or the termination or expiration of this Agreement pursuant to its terms, unless Buyer shall otherwise consent in writing, which consent shall not be unreasonably

Page 36 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

withheld or delayed, and except for actions taken pursuant to Assumed Contracts, or which are required by Law or arise from or are related to the anticipated transfer of the Assets or as otherwise contemplated by this Agreement or disclosed in Schedule 6.3 or another Schedule to this Agreement, Sellers shall:

              (a)  Operate and maintain the Assets only in the usual and ordinary course, materially consistent with practices followed prior to the execution of this Agreement;

              (b)  Except as required by their terms, not amend, terminate, renew, or renegotiate any existing material Assumed Contract or enter into any new Assumed Contract, except in the ordinary course of business and consistent with practices of the recent past, or default (or take or omit to take any action that, with or without the giving of notice or passage of time, would constitute a default) in any of its obligation under any such contracts;

              (c)  Not (i) sell, lease, transfer or dispose of, or make any contract for the sale, lease, transfer or disposition of, the LLC Interests or any assets or properties which would be included in the Assets, other than sales in the ordinary course of business which would not individually, or in the aggregate, have a Material Adverse Effect upon the operations or value of the Plant or the LLC Interests; (ii) incur, assume, guaranty, or otherwise become liable in respect of any indebtedness for money borrowed which would result in the LLC or Buyer assuming such liability hereunder after the Closing; (iii) delay the payment and discharge of any liability which, upon Closing, would be an Assumed Liability, because of the transactions contemplated hereby; or (iv) encumber or voluntarily subject to any lien any Asset or LLC Interest (except for Permitted Encumbrances); or (v) sell, lease, transfer or dispose of, to any Seller or any Affiliate of any Seller, any LLC Interest or any assets or properties which would be included in the Assets, or remove any such assets or property to or for the benefit of any Seller or any Affiliate of any Seller;

              (d)  Maintain in force and effect the material property and liability insurance policies related to the Assets;

              (e)  Subject to Section 6.2, not take any action which would cause any of Sellers' representations and warranties set forth in Article 3 to be materially false as of the Closing;

              (f)  Not make Capital Expenditures, other than those contemplated on Schedule 2.6(f)(i), which would, pursuant to the provisions of Section 2.6(f), result in an upward adjustment of the Purchase Price pursuant to Section 2.6(f)(i) in excess of $1,000,000 in the aggregate, except for purchases under agreements in existence as of the date hereof that would constitute Assumed Liabilities as of such date, Capital Expenditures set forth on Schedule 2.6(f)(i), or Capital Expenditures otherwise approved in writing by Buyer;

Page 37 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

              (g)  Not (i) adopt any new plan or program for severance, continuation or termination pay for employees at the Plant, (ii) enter into any new collective bargaining agreement or any amendment to the existing collective bargaining agreement for employees at the Plant, (iii) increase benefits payable under any Benefit Plan, (iv) increase compensation payable to employees at the Plant, (v) represent to any employee at the Plant that Buyer would assume or continue to maintain any Benefit Plan after the Closing Date, or (vi) hire out or transfer any employees to or from the Plant unless essential to maintain the business or operations of the Plant.

Provided that nothing in this Section shall (i) obligate Sellers to make expenditures other than in the ordinary course of business and consistent with practices of the recent past or to otherwise suffer any economic detriment, (ii)  preclude Sellers from paying, prepaying or otherwise satisfying any liability which, if outstanding as of the Closing Date, would be an Assumed Liability or an Excluded Liability, (iii) preclude Sellers from incurring any liabilities or obligations to any third party in connection with obtaining such party's consent to any transaction contemplated by this Agreement, the Related Agreements or any other agreement contemplated hereby, provided such liabilities and obligations under this clause (iii) shall be Excluded Liabilities pursuant to Section 2.4(h) hereof if not approved in advance by Buyer (which approval shall not be unreasonably withheld or delayed), or (iv)  preclude Sellers from instituting or completing any program designed to promote compliance or comply with Laws or other good business practices respecting the Plant.

     Section 6.4  Environmental Matters.

              (a)  Remediation of Existing Soils Contamination. Subject to the terms and conditions of this Agreement, including but not limited to the terms and conditions of this Section, Sellers shall remain responsible for the cost and performance of Remediation Measures. In addition, subject to Section 6.4(b), the Sellers may undertake such Remediation Measures when and as they reasonably determine are required under Environmental Law or which they otherwise reasonably believe are appropriate. Notwithstanding the foregoing, Sellers shall have no obligation to undertake Remediation Measures in respect of environmental conditions that are excluded from Sellers' Environmental Obligations by virtue of the provisos to Section 1.1(r) and neither shall the Sellers have any responsibility for the cost or performance of Remediation Measures undertaken by the Buyer, any Buyer Subsidiary or any Affiliate of Buyer or of any Buyer Subsidiary, except to the extent such costs are included in Losses (as defined in Section 12.3(a)) for which Buyer or such Buyer Subsidiary is entitled to indemnification under Article 12. With respect to any Remediation Measure undertaken by Sellers pursuant to the first sentence of this paragraph, Sellers shall be deemed to have discharged such undertaking and their obligation with respect thereto whenever they have paid the cost of such Remediation Measure and they have either received written notice from the pertinent Governmental Body or Bodies that no further material Remediation Measures are then required with respect to the Existing Soils Contamination in question or, if

Page 38 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

such Governmental Body or Bodies have not responded within a reasonable time to Sellers' request for such written notice, whenever Sellers have reasonably and in good faith determined that no such further material Remediation Measures are then required.

              (b)  Performance of Work. Prior to commencing any Remediation Measures after the Closing or presenting after the Closing any plan for Remediation Measures to any Governmental Body having jurisdiction over such Remediation Measures or to any Person making a Third Party Claim for which Sellers are responsible under the provisions of Article 12, the Sellers Group shall meet and consult with Buyer in good faith concerning such Remediation Measures or plan, as the cases may be. In connection with the performance of any Remediation Measures by Sellers, the Sellers Group shall:

                   (i)     Provide Buyer with reasonable notice of any meetings
     with any such Governmental Body or any such other Person to afford Buyer or
     its representatives the right to participate in such meetings, and provide Buyer
     with copies of all correspondence and documents (hard copy or electronic) to
     and from such Governmental Body or other Person;

                   (ii)    Provide the Buyer with a reasonable opportunity to
     preview and comment upon any submissions the Sellers Group plans to deliver
     or submit to any such Governmental Body or any such other Persons and
     incorporate Buyer's requests which are reasonably justified to avoid adverse
     impact in accordance with paragraph (iii) below;

                   (iii)   Meet and consult with the Buyer in good faith over the
     time, manner and conditions for the completion of the Remediation Measures,
     so as to avoid, to the extent reasonably practicable and consistent with the
     effective, economical, efficient and timely completion of the Remediation
     Measures, unreasonable interference with business conducted or planned to be

In the event that, despite Sellers' efforts to cure, the Title Insurer remains unwilling to issue any such Title Policy on the Closing Date (as may be extended as provided herein), then Buyer, at its option, may terminate this Agreement. Notwithstanding the foregoing, Buyer may elect to cause the LLC to accept such title to any such property interests as the Sellers may be able to convey, and such title insurance with respect to the same as the Title Insurer is willing to issue, in which case such interests shall be conveyed as part of the Assets without reduction of the Purchase Price or any credit or allowance against the same and without any other liability on the part of Sellers.

     acknowledged by the LLC with respect to each Real Property Lease included in the
     Assets; and

                     (ii)    An assumption agreement or assumption agreements in favor of Sellers.

     Section 10.3  Escrow. If either the Buyer or the Sellers Group desires to consummate the Closing through an escrow, an escrow shall be opened with, and the escrow agent shall be, the Title Insurer or an Affiliate thereof (the "Escrow Agent"), by depositing a fully executed copy of this Agreement with the Escrow Agent to serve as escrow instructions. This Agreement shall be considered the primary escrow instructions between the parties, but the parties shall execute such additional standard escrow instructions as the Escrow Agent shall require in order to clarify the duties and responsibilities of the Escrow Agent. In the event of any conflict between this Agreement and such additional standard escrow instructions, this Agreement shall prevail. If the Closing is to be consummated through the Escrow Agent, the parties shall deliver the funds, instruments of sale, assignment, conveyance and assumption called for by Sections 10.1 and 10.2 to the Escrow Agent, and on the Closing Date, the Escrow Agent shall close the escrow by:

                (a)  Causing the deeds for the Owned Real Properties, the assignment of the Real Property Leases, and any other documents which the parties may mutually designate to be recorded in the official records of the appropriate counties in which the pertinent Assets are located;

                (b)  Delivering to Sellers by wire transfer of immediately available funds, to an account or accounts designated by Sellers, the amounts called for in Section 10.2; and

                (c)  Delivering to Buyer or Sellers, as the case may be, the other instruments referred to in Section 10.2.

     Section 10.4  Prorations. Items of expense and income (if any) affecting the Assets and the Assumed Liabilities that are customarily pro-rated, including, without limitation, real and personal property taxes, utility charges, charges arising under leases, insurance premiums, and the like, shall be pro-rated between Sellers and Buyer and the pertinent Buyers Subsidiaries as of the Closing Date.

     Section 11.1  Termination. Any transactions contemplated hereby that have not been consummated may be terminated:

Page 53 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

                (a)  At any time, by mutual written consent of the Sellers Group and Buyer; or

                (b)  By either Buyer or the Sellers Group, as the case may be, upon 30 days' written notice given any time after (i) the issuance of an order by a Governmental Body in a manner that fails to meet the conditions of the terminating party set forth in Sections 8.4 or 9.4, as the case may be, (ii) 180 days have elapsed from the filing after the date hereof of all applications for approval of this Agreement and the transactions contemplated hereby by Governmental Bodies and a final order has not been obtained with respect to each such Application, it being understood that such 180-day period shall not include any period after such order during which applications for rehearing or modification or judicial appeals or remedies are pending; or

                (c)  By one Party upon written notice to the other if there has been a material default or breach under this Agreement by another party which is not cured by the earlier of the Closing Date or the date 30 days after receipt by the other party of written notice from the terminating party specifying with particularity such breach or default; or

                (d)  By either Buyer or the Sellers Group upon written notice to the other Party, if (i) the Closing shall not have occurred by the Termination Date; or (ii) (A) in the case of termination by the Sellers Group, the conditions set forth in Article 9 for the Closing cannot reasonably be met by the Termination Date and (B) in the case of termination by Buyer, the conditions set forth in Article 8 for the Closing cannot reasonably be met by the Termination Date, unless in either of the cases described in clauses (A) or (B), the failure of the condition is the result of the material breach of this Agreement by the party seeking to terminate. The Termination Date for the Closing shall be the date that is twelve months from the date hereof. Such date, or such later date as may be specifically provided for in this Agreement (including any date arising under operation of Sections 8.6 and 8.8(a) hereof) or agreed upon by the parties, is herein referred to as the "Termination Date." Each Party's right of termination hereunder is in addition to any other rights it may have hereunder or otherwise.

     Section 11.2  Effect of Termination. If there has been a termination pursuant to Section 11.1, then this Agreement shall be deemed terminated, and all further obligations of the parties hereunder shall terminate, except that the obligations set forth in Sections 5.3, 11.1(b) and in Articles 12 and 13.9 shall survive. In the event of such termination of this Agreement, there shall be no liability for damages on the part of a party to another under and by reason of this Agreement or the transactions contemplated hereby except as set forth in Article 12 and except for intentionally fraudulent acts by a party, the remedies for which shall not be limited by the provisions of this Agreement. The foregoing provisions shall not, however, limit or restrict the availability of specific performance or other injunctive or equitable relief to the extent that specific performance or such other relief would otherwise be available to a party hereunder.

Page 54 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

     Section 11.3  Modification of Terms. In the event any Governmental Body entertains, as an alternative to approval of this Agreement, the Related Agreements and any other agreement contemplated hereby, any proposal of one or more third parties to acquire the Assets from Sellers on terms and conditions that include a higher purchase price than the Purchase Price set forth herein, and such terms and conditions are acceptable to Sellers, then and in that event, subject to such restrictions and requirements as such Governmental Body may impose upon Sellers, Sellers shall exercise their best efforts to afford to Buyer the right to enter into appropriate amendments and modifications of this Agreement to match such proposed alternate terms and conditions. Buyer shall be entitled to exercise such right by delivery of written notice thereof to Sellers within three Business Days after its receipt of written notice from Sellers that, in Sellers' good faith belief, the proposals of such third party or parties makes it unlikely that such Governmental Body will approve this Agreement and the transactions contemplated hereby in a timely fashion and that the alternate terms and conditions are acceptable to Sellers. If such right is not exercised and such Governmental Body proceeds to decline to grant its approval, the termination provisions of Section 11.1 shall apply.

     Section 12.1  Survival. Except as may be otherwise expressly set forth in this Agreement, the representations, warranties, covenants and agreements of Buyer and Sellers set forth in this Agreement, or in any writing required to be delivered in connection with this Agreement, shall survive the Closing Date.

     Section 12.2  Exclusive Remedy. Absent intentional fraud or unless otherwise specifically provided herein, the sole exclusive remedy for damages of a party hereto for any breach of the representations, warranties, covenants and agreements of the other party contained in this Agreement shall be the remedies contained in this Article 12.

     Section 12.3  Indemnity by Sellers.

                (a)  Sellers shall indemnify and hold harmless the LLC (from and after the Closing), Buyer, each Buyer Subsidiary, and each Affiliate of Buyer or any Buyer Subsidiary from and against any and all claims, demands, suits, losses, liabilities, damages and expenses, including reasonable attorneys' fees and costs of investigation, litigation, settlement and judgment, and including any costs and expenses incurred by any such Indemnitee as a result or arising out of any obligation or election (whether arising out of or in connection with any Law, any contract, any Charter Document, or otherwise) of any such Indemnitee to indemnify its directors, officers, attorneys, employees, subcontractors, agents and assigns (collectively "Losses"), which they or any of them may sustain or suffer or to which they or any of them may become subject as a result of:

                     (i)     Written notice to Sellers of such claim specifying the basis
     thereof must be made, or an action at law or in equity with respect to such claim
     must be served, before the second anniversary of the earlier to occur of the
     Closing Date or the date on which this Agreement is terminated, as the case may
     be, except that such time limitation shall not apply to breaches of the covenants
     contained in Sections 2.10, 6.4, 6.7 or 6.10;

                     (ii)    If the Closing occurs, the LLC, Buyer, the Buyer
     Subsidiaries and their respective Affiliates shall be entitled only to recover the
     amount by which the aggregate Losses sustained or suffered by them exceed one
     percent of the Purchase Price (the "Deductible Amount"), provided, however,
     that individual claims of $5,000 or less shall not be aggregated for purposes of
     calculating either the Deductible Amount or the excess of Losses over the
     Deductible Amount and Buyer shall be entitled to recover on a dollar for dollar
     basis all claims for Losses covered under insurance maintained by Sellers;
     provided further that recovery of Losses sustained or suffered as a result of
     Sellers' failure to perform under Sections 6.7 or 6.10 shall not be limited by the

     Amount or the excess of Losses over the Deductible Amount; and

Page 57 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

                     (iii)   If the Closing occurs, in no event shall the LLC, Buyer and its
     Affiliates be liable to Sellers or their respective Affiliates for Losses in the nature of
     consequential damages, incidental damages, indirect damages, punitive damages,
     special damages, lost profits, damage to reputation or the like, but such damages shall
     be limited to out-of-pocket Losses and diminution in value and all Losses shall be
     limited to an aggregate limit under this Agreement and the Related Agreements and the
     Transmission Arrangements of $556,000,000.

     Section 12.5  Further Qualifications Respecting Indemnification. The right of a party (an "Indemnitee") to indemnity hereunder shall be subject to the following additional qualifications:

                (a)  The Indemnitee shall promptly upon its discovery of facts or circumstances giving rise to a claim for indemnification, including receipt by it of notice of any demand, assertion, claim, action or proceeding, judicial, governmental or otherwise, by any third party (such third party actions being collectively referred to herein as "Third Party Claims"), give notice thereof to the indemnifying party (the "Indemnitor"), such notice in any event to be given within 60 days from the date the Indemnitee obtains actual knowledge of the basis or alleged basis for the right of indemnity or such shorter period as may be necessary to avoid material prejudice to the Indemnitor provided, however, the failure to provide or timely provide the Indemnitor with notice of any Third Party Claim shall only affect the Indemnitee's rights to indemnification to the extent that the Indemnitor is materially prejudiced as a result of the Indemnitee's failure to give timely notice of such Third Party Claim; and

                (b)  In computing Losses, such amounts shall be computed net of any related recoveries to which the Indemnitee is entitled under insurance policies, or other related payments received or receivable from third parties, and net of any tax benefits actually received by the Indemnitee or for which it is eligible, taking into account the income tax treatment of the receipt of indemnification.

     Section 12.6  Procedures Respecting Third Party Claims. In providing notice to the Indemnitor of any Third Party Claim (the "Claim Notice"), the Indemnitee shall provide the Indemnitor with a copy of such Third Party Claim or other documents received and shall otherwise make available to the Indemnitor all relevant information material to the defense of such claim and within the Indemnitee's possession. The Indemnitor shall have the right, by notice given to the Indemnitee within 15 days after the date of the Claim Notice, to assume and control the defense of the Third Party Claim that is the subject of such Claim Notice, including the employment of counsel selected by the Indemnitor after consultation with the Indemnitee, and the Indemnitor shall pay all expenses of, and the Indemnitee shall cooperate fully with the Indemnitor in connection with, the conduct of such defense. The Indemnitee shall have the right to employ separate counsel in any such proceeding and to participate in (but not control) the defense of such Third Party Claim, but the fees and expenses of such counsel shall be

Page 58 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

borne by the Indemnitee unless the Indemnitor shall agree otherwise; provided, however, if the named parties to any such proceeding (including any impleaded parties) include both the Indemnitee and the Indemnitor, the Indemnitor requires that the same counsel represent both the Indemnitee and the Indemnitor, and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them, then the Indemnitee shall have the right to retain its own counsel at the cost and expense of the Indemnitor. If the Indemnitor shall have failed to assume the defense of any Third Party Claim in accordance with the provisions of this Section, then the Indemnitee shall have the absolute right to control the defense of such Third Party Claim, and, if and when it is finally determined that the Indemnitee is entitled to indemnification from the Indemnitor hereunder, the fees and expenses of Indemnitee's counsel shall be borne by the Indemnitor, provided that the Indemnitor shall be entitled, at its expense, to participate in (but not control) such defense. The Indemnitor shall have the right to settle or compromise any such Third Party Claim for which it is providing indemnity so long as such settlement does not impose any obligations on the Indemnitee (except with respect to providing releases of the third party). The Indemnitor shall not be liable for any settlement effected by the Indemnitee without the Indemnitor's consent except where the Indemnitee has assumed the defense because Indemnitor has failed or refused to do so. The Indemnitor may assume and control, or bear the costs, of any such defense subject to its reservation of a right to contest the Indemnitee's right to indemnification hereunder, provided that it gives the Indemnitee notice of such reservation within 15 days of the date of the Claim Notice.

     Section 14.1  Function. Pursuant to a separate agreement among the Sellers, the Sellers have formed a committee (the "Sellers Committee") charged with administering this

Page 65 - CENTRALIA PLANT PURCHASE AND SALE AGREEMENT

Agreement on behalf of the Sellers and determining what actions should be taken hereunder by the Sellers Group.

     Section 15.1  Sale of Portland General Electric Company's ("PGE's") Interest to Avista Corporation ("Avista"). The parties are aware that PGE has entered into an agreement to sell its 2.5% interest to Avista. Avista hereby represents and warrants to the other Sellers that at the close of the sale of PGE's interest to Avista, Avista shall fully assume all of PGE's rights and obligations with respect to said interest under all applicable agreements among the owners of the Plant, including this Agreement and the Centralia Fuel Supply Agreement and the parties to this Agreement consent to such sale, and agree that at such time, PGE shall thereafter be released from its obligations as a Seller under this Agreement, and the parties to this Agreement shall thereafter look to Avista as the Seller with respect to said 2.5% interest; provided, however subsequent to such sale, PGE shall refrain from any effort to interfere in the consummation of the transactions contemplated by this Agreement and the Related Agreements and the Transmission Arrangements. The Sellers hereby waive any and all rights of first refusal pursuant to Section 24(e) of the Agreement for the Construction and Ownership of Centralia Steam Electric Generating Plant of May 15, 1969. PGE and Avista shall ensure that Buyer and Other Sellers are promptly notified of the closing between Avista and PGE.

     IN WITNESS WHEREOF, the parties have duly executed this Agreement on the date first above written.
