-74-

Operating Agent’s labor charges included in Section 21.7.1 hereof by the “Payroll Tax Ratio,” the “Worker’s Compensation Ratio” and the “Benefits Ratio” determined pursuant to Appendix F, H and G, respectively hereto. Estimated ratios shall be used and year-end adjustments shall be made in a manner similar to that described in Sections E.2 and E.3 of Appendix E hereto.

21.7.4 If any Capital Improvements are made by the Operating Agent’s employees, the amount of the Operating Agent’s administrative and general expenses allocable to such Capital Improvements shall be determined by multiplying the sum of the Operating Agent’s labor charges included in Section 21.7.1 hereof by a decimal fraction hereinafter referred to as the “Capital Improvements A&G Ratio” as determined pursuant to Appendix J hereto. Estimated ratios shall be used and year-end adjustments shall be made in a manner similar to that described in Sections E.2 and E.3 of Appendix E hereto.

21.8 If any Capital Improvements are made by a contractor, the amount of the Operating

-75-

Agent’s administrative and general expenses allocable to such Capital Improvements shall be determined by multiplying the total work order cost thereof by one percent (1.00%). As used herein, “total work order cost” does not include the costs of injuries and damages, claims, taxes, other than sales and use taxes, and interest incurred by the Operating Agent or any other of the Operating Agent’s noncontracted costs during the construction of Capital Improvements; however, costs of administration of the injuries and damages program are included.

21.9 Units of Property retired from service, whether considered original construction or Capital Improvements, shall be disposed of by the Operating Agent on the best available terms as soon as practicable, and the proceeds, if any, received therefrom shall be credited or distributed to the Participants in proportion to their Cost Responsibility in the Component of which the Units of Property retired from service are a part.

23. GENERAL PROVISIONS AFFECTING PROJECT INSURANCE

Except as otherwise directed by the Administrative Committee, the following provisions shall apply to the Project Insurance obtained by the Project Manager or Operating Agent in compliance with Section 22 hereof.

23.1 Except for Project Insurance described in Sections 22.1.1.4, 22.1.2.2, 22.1.3, 22.2.1.4 and 22.2.3 hereof, each Participant shall be named an additional insured, individually and jointly with the other Participants, on all policies of Project Insurance, and the policies

-84-

of Project Insurance referred to in Sections 22.1.1 and 22.2.1 hereof shall carry cross-liability endorsements.

23.2 Such insurance coverages as required under Section 22 hereof shall be written with deductibles and limits as approved by the Administrative Committee. The Administrative Committee may, at any time, increase the policy(ies) limits, eliminate coverage(s) or require additional policies not previously specified, and shall determine appropriate deductibles, retentions and other special terms and conditions of Project Insurance.

23.3 Any deductibles shall be apportioned among the Participants on the basis set forth in Section 24.3 hereof, except that deductibles under any worker’s compensation insurance carried for officers and employees of the Project Manager and Operating Agent shall be apportioned in the manner specified in Appendix E hereto.

23.4 Project Insurance policies shall be primary insurance for all purposes and shall be so endorsed. Any other insurance carried by a Participant individually shall not participate with Project Insurance as to any loss or claim for which valid and collectible Project Insurance

-85-

shall apply. Such other insurance shall apply solely as to the individual interest of the Participant carrying such other insurance; provided, however, that each Participant shall accept any reasonably restrictive endorsement to its separate insurance policies as may be required by an insurer as a condition precedent to the issuance of a policy of Project Insurance.

23.5 At the direction of the Project Manager or Operating Agent, any party furnishing services, materials, parts or equipment in connection with the planning, design, engineering, construction, maintenance, operation or use of property of the Transmission System or the Microwave System may be named as an insured as its interest may appear in any of the Project Insurance policies, and either the Project Manager or the Operating Agent may waive on behalf of each Participant its right of recovery against any such party for insured loss for damage to any property covered by Project Insurance as required in Sections 22 and 23 hereof, provided that no such waiver shall impair the right to recover any sums otherwise payable to any Participant under the Project Insurance.

-86-

23.6 The Project Manager and Operating Agent respectively shall furnish the other Participants with a certified copy of each of the policy forms of Project Insurance, together with a line sheet therefor (and any subsequent amendments) naming the insurers and underwriters and the extent of their participation.

23.7 Each of the Project Insurance policies shall be endorsed so as to provide that the Participants and additional named insureds pursuant to Section 23.5 hereof shall be given the same advance notice of cancellation or material change as that required to be given to the Project Manager or Operating Agent.

23.8 In the event the Administrative Committee is unable to agree upon any matters relating to Project Insurance not governed by Sections 22 and 23 hereof, the Project Manager or Operating Agent, pending the resolution of such disagreement, shall procure or cause to be procured, such policies of Project Insurance as in its best judgment are necessary and required to protect the Participants against the insurable risks more particularly set forth in Section 22 hereof. During any period of negotiations with an insurer, or other negotiations which are

-87-

pending at the expiration of the period of coverage of a Project Insurance policy, or in the event a Project Insurance policy is cancelled, the Project Manager and Operating Agent shall renew or bind policies as an emergency measure or may procure policies of insurance which are identical to those which were cancelled, or may, to the extent possible, secure replacement policies which will provide substantially the same coverage as the policy expiring or cancelled.

23.9 Each Participant shall have the right to have any mortgagee, trustee or secured party named on all or any of the Project Insurance policies as loss payee or additional insured as its interest may appear, by notice to the Project Manager or Operating Agent given in writing not less than ninety (90) days prior to the procurement or renewal of the Project insurance policy(ies), which such notice shall specify the name or names of such mortgagee, trustee or secured party and such additional information as may be necessary or required to permit it to be included on the policy(ies) of Project Insurance.

23.10 Unless otherwise directed by the Administrative Committee, the Project Manager and

-88-

Operating Agent shall obtain Project Insurance from such insurers or underwriters, including stock companies, mutuals and pools or groups of insurers or underwriters, as either of them in its sole discretion may select, provided that any policy which obligates any Participant to pay any assessment shall not be obtained unless such Participant has agreed in writing to undertake such obligation.

23.11 Any refunds of premiums or dividends received by the Project Manager or Operating Agent on any Project Insurance shall be allocated among the Participants in proportion to their Cost Responsibility in the affected Component or, where applicable, in proportion to their Cost Responsibility for the Microwave System, at the time of receipt thereof, provided that any reserve premium refunds received under any policy with a retrospective rating plan shall be allocated among the Participants at the time of payment of the reserve premium in proportion to their Cost Responsibility in the Components or where applicable, in proportion to their Cost Responsibility for the Microwave System at such time.

-89-

23.12 Nothing herein shall prohibit the Project Manager or Operating Agent from combining the coverage required by this Participation Agreement with coverage outside the scope of that required by this Participation Agreement. If the Project Manager or Operating Agent does so combine coverages, the Administrative Committee shall determine the portion of the total premium cost which is allocable to Construction Insurance or Operating Insurance. If the Administrative Committee is unable to determine such allocation, the Project Manager or Operating Agent, as the case may be, may make an estimated allocation and xxxx the Participants on the basis thereof, with adjustment to be made when the dispute is resolved.

23.13 Except as provided in Section 23.9 hereof, if any Participant desires changes in any policy of Project Insurance, such Participant shall request in writing to the Project Manager or Operating Agent, as the case may be, to have the desired changes made. Upon receipt of any such request the Project Manager or Operating Agent shall promptly determine whether or not the desired change can be made and the effect thereof upon the coverage afforded each other Participant

-90-

and upon insurance premiums. If the Project Manager or Operating Agent determines that the desired changes (i) can be made, (ii) will not reduce the coverage otherwise afforded to any Participant, and (iii) will not result in any increase in premium expense or if an increase in premium expense will result and the requesting Participant agrees in writing to pay such increase, then the Project Manager or Operating Agent shall cause such desired changes to be made at the earliest feasible time. If the Project Manager or Operating Agent determines that the desired changes can be made but to do so (i) will result in a reduction in coverage otherwise afforded to any Participant, or (ii) will result in an increase in premium expense shared by the Participants, such request shall be referred to the Adminstrative Committee for resolution.

24. LIABILITY

24.1 Except for any judgment debt for damage resulting from Willful Action and except to the extent any judgment debt is collectible from valid Project Insurance, each Participant hereby extends to all other Participants, and their respective directors, officers, agents and employees its covenant not to execute on any

-91-

judgment obtained against such other Participants for direct, indirect or consequential loss, damage, cost, charge or expense, whether or not resulting from the negligence of a Participant, its directors, officers, agents, employees or any other person or entity whose negligence would be imputed to such Participant, arising from physical damage to its property, which results from the performance or non-performance of the obligations of a Participant under the Project Agreements.

24.2 In the event any insurer providing Project Insurance refuses to pay any judgment obtained by a Participant against another Participant, or any of its directors, officers or employees, on account of liability referred to in Section 24.1 hereof, the Participant or any of its directors, officers or employees against whom the judgment is obtained shall, at the request of the Participant obtaining the judgment and in consideration for the covenant given in Section 24.1 hereof, execute such documents as may be necessary to effect an assignment of its or their contractual rights against the non-paying insurer.

-92-

24.3 Except for Work Liability resulting from Willful Action and except as provided in Section 24.5 hereof, the costs and expenses of discharging all Work Liability imposed upon one or more of the Participants, for which payment is not made by Project Insurance, shall be allocated among the Participants in proportion to their Cost Responsibility in the Components involved in the operative facts which give rise to the Work Liability or in proportion to their Cost Responsibility for the Microwave System if such operative facts are associated with the Microwave System. However, if the proximate cause of such liability cannot be determined or is not related to any particular Component, then such costs and expenses shall be allocated among the Participants in proportion to their composite Cost Responsibility in the Transmission System as shown in Appendix B hereto.

24.4 Each Participant shall be responsible for the consequences of its own Willful Action and shall indemnify and hold harmless the other Participants from consequences thereof to the extent that such consequences are not covered by valid and collectible Project Insurance.

-93-

24.5 Except for liability resulting from Willful Action, any Participant whose electric customer shall have a claim or bring an action against any other Participant for any death, injury, loss or damage arising out of or in connection with interruptions to or curtailment of electric service to such customer caused by the operation or failure of operation of the Transmission System or any portion thereof shall indemnify and hold harmless such other Participant, its directors, officers and employees, from and against any liability for such death, injury, loss or damage.

24.6 The provisions of this Section 24 shall not be construed so as to relieve any insurer of its obligation to pay any insurance proceeds in accordance with the terms and conditions of valid and collectible Project Insurance policies.

24.7 In the event that the parties to the ANPP Participation Agreement amend Section 21 (LIABILITY) of that Agreement during the term hereof, then the Participants to this Agreement agree to negotiate in good faith to consider analogous language to replace or supplement the provisions of this Section 24. Provided,

-94-

however, that it is understood the Participants' respective levels of authority and the monetary risks associated with Willful Action may differ between the ANPP Participation Agreement and this Agreement.

Project Agreements.

26.4 In the event that any Participant shall dispute the existence or nature of a default asserted in a notice given pursuant to Section 26.2 hereof, then such Participant shall pay the disputed payment or perform the disputed obligation but may do so under protest. The protest shall be in writing, shall precede or accompany the disputed payment or precede the performance of the disputed obligation and shall specify the reasons upon which the protest is based. Copies of such protest shall be mailed by such Participant to all other Participants. Payments not made under protest shall be deemed to be correct, except to the extent that periodic or annual audits may reveal over or under payments by Participants, necessitating adjustments. In the event it is determined by arbitration, pursuant to the provisions of this Participation Agreement or otherwise, that a protesting Participant is entitled to a refund of all or any portion of a disputed payment or payments or is entitled to the reasonable equivalent in money of non-monetary performance of a disputed obligation theretofore made, then, upon such determination, the non-protesting

-100-

Participants shall pay such amount to the protesting Participant, together with interest thereon at the rate of six percent (6%) per annum from the date of payment or from the date of completion of performance of a disputed obligation to the date of reimbursement. Reimbursement of the amount so paid shall be made by the non-protesting Participants in the ratio of their respective Cost Responsibilities in the Components or, where applicable, in the Microwave System, to the total of the Cost Responsibilities in the Components, or, where applicable, in the Microwave System, of all non-protesting Participants.

26.5 Unless otherwise determined by a board of arbitrators, in the event a default by any Participant in the payment or performance of any obligation under the Project Agreements shall continue for a period of six (6) months or more without having been cured by the defaulting Participant or without such Participant having commenced or continued action in good faith to cure such default, or in the event the question of whether an act of default exists becomes the subject of an arbitration pursuant to Section 27 hereof, and such act continues for a period of

-101-

six (6) months following a final determination by a board of arbitrators or otherwise that an act of default exists and the defaulting Participant has failed to cure such default or to commence such action during said six (6) month period, then, at any time thereafter and while said default is continuing, all of the non-defaulting Participants, by written notice to all Participants, may suspend the right of the defaulting Participant (i) to be represented on and participate in the actions of all committees, and (ii) to use all or any part of its proportionate share of rights in the Transmission System in which event:

26.5.1 During the period that such suspension is in effect, the non-defaulting Participants (i) shall bear all of the operation and maintenance costs, insurance costs and other expenses, otherwise payable by the defaulting Participant under the Project Agreements, and (ii) shall be entitled to schedule and receive for their respective accounts the transmission rights of the defaulting Participant for all Components in the ratio of their respective Cost Responsibilities in the Components to

-102-

the total of the Cost Responsibilities in the Components of all non-defaulting Participants.

26.5.2 A defaulting Participant shall be liable to the non-defaulting Participants for all costs incurred by such non-defaulting Participants pursuant to Section 26.5.1 hereof plus interest as provided in Section 26.3 hereof. The proceeds paid by any defaulting Participant to remedy any such default shall be distributed to the non-defaulting Participants in proportion to the cost actually paid by the non-defaulting Participants to remedy the default involved herein.

26.5.3 The suspension of any defaulting Participant shall be terminated and its full rights hereunder restored when all of its defaults have been cured and all costs incurred by non-defaulting Participants pursuant to Section 26.5.1 plus interest as provided in Section 26.3 hereof have been paid by the defaulting Participant or other arrangements suitable to all non-defaulting Participants have been made.

26.6 In addition to the remedies provided

-103-

in Section 26.5 hereof the non-defaulting Participants may, in submitting a dispute to arbitration in accordance with the provisions of Section 27 hereof, request that the board of arbitrators determine what additional remedies may be reasonably necessary or required under the circumstances which gave rise to the dispute. The board of arbitrators may determine what remedies are necessary or required in the premises, including but not limited to the conditions under which the Transmission System may be operated economically and efficiently during periods when the defaulting Participant's right to receive its proportionate share of the transmission rights is suspended.

26.7 The rights and remedies of the Participants set forth in this Participation Agreement shall be in addition to the rights and remedies of the Participants set forth in any other of the Project Agreements.

27. ARBITRATION

27.1 If a dispute between any of the Participants should arise under the Project Agreements, any Participant(s) may call for submission of the dispute to arbitration which shall be binding upon all of the other

-104-

Participants.

27.2 The Participant(s) calling for arbitration shall give written notice to all other Participants, setting forth in such notice in adequate detail the nature of the dispute including the specific issues to be resolved by arbitration, the amount or amounts, if any, involved in such dispute, and the remedy sought by such arbitration proceedings and, within twenty (20) days from receipt of such notice, any other Participant(s) involved may, by written response to the first Participant(s) and all other Participants, submit its or their own statement of the matter at issue and set forth in adequate detail additional related matters or issues to be arbitrated. Thereafter, the Participant(s) first submitting its or their notice of the matter at issue shall have ten (10) days in which to submit a written rebuttal statement, copies of which shall be given to all other Participants.

27.3 Within forty (40) days following delivery of the written notice by a Participant calling for arbitration pursuant to Section 27.2 hereof, the Participants, acting through their representatives on the Administrative Committee,

-105-

shall meet for the purpose of selecting arbitrators. Each Participant or group of Participants representing one side of the dispute shall designate an arbitrator. The arbitrators so selected shall meet within twenty (20) days following their selection and shall select additional arbitrators, the number of which shall be one (1) less than the total number of arbitrators selected by the Participants. If the arbitrators selected by the Participants, as herein provided, shall fail to select such additional arbitrator(s) within said twenty (20) day period, then the arbitrators shall request from the American Arbitration Association (or a similar organization if the American Arbitration Association should not at the time exist) a list of arbitrators who are qualified and eligible to serve as hereinafter provided. The arbitrators selected by the Participants shall take turns striking names from the list of arbitrators furnished by the American Arbitration Associaiton, and the last name(s) remaining on said list shall be the additional arbitrator(s). All arbitrators shall be persons skilled and experienced in the field which gives rise to the dispute, and no person shall be eligible for

-106-

appointment as an arbitrator who is an officer or employee of any of the parties to the dispute or is otherwise interested in the matter to be arbitrated.

27.4 Except as otherwise provided in this Section 27, the arbitration shall be governed by the rules and practice of the American Arbitration Association (or the rules and practice of a similar organization if the American Arbitration Association should not at that time exist) from time to time in force, except that if such rules and practice, as modified herein, shall conflict with state or federal law, as the case may be, then in force which are specifically applicable to such arbitration proceedings, such law shall govern.

27.5 Included in the issues which may be submitted to arbitration pursuant to this Section 27 is the issue of whether the right to arbitrate a particular dispute is permitted under the Project Agreements.

27.6 The arbitrators shall hear evidence submitted by the respective Participants and may call for additional information, which additional information shall be furnished by the Participant(s) having such information. The

-107-

decision of a majority of the arbitrators shall be binding upon all the Participants.

27.7 The award of the arbitrators shall contain findings with respect to the issues involved in the dispute and relative to the materiality of the default, the period of time within which the defaulting party must remedy the default or commence remedial action, and the remedies which may be exercised by the non defaulting Participants in the event the default is not remedied within such period of time.

27.8 This agreement to arbitrate shall be specifically enforceable, and the award and findings of the arbitrators shall be final and binding upon the Participants to the extent permitted by applicable law. Any award may be filed with the clerk of any court having jurisdiction over the Participants, or any of them, against whom the award is rendered and, upon such filing, such award, to the extent permitted by the laws of the jurisdiction in which said award is filed, shall be specifically enforceable or shall form the basis of a declaratory judment or other similar relief.

27.9 The fees and expenses of the arbitrators shall be shared by the Participants

-108-

equally, unless the decision of the arbitrators shall specify some other apportionment of such fees and expenses. All other expenses and costs of the arbitration shall be borne by the Participant incurring the same.

27.10 In the event that any Participant shall attempt to carry out the provisions herein set forth in regard to arbitration, and such Participant shall not be able to obtain a valid and enforceable arbitration decree, such Participant shall be entitled to seek legal remedies in the courts having jurisdiction in the premises, and the provisions of the Project Agreements referring to decisions of a board of arbitration, to the extent allowable by law, shall be then deemed applicable to final decisions of such courts.

28. ACTIONS PENDING RESOLUTION OF DISPUTES

28.1 If a dispute should arise which is not resolved by the Administrative Committee or the higher authorities within the Participants' organizations, then, pending the resolution of the dispute by arbitration or judicial proceedings, the Project Manager or Operating Agent shall proceed with Construction Work, Operating Work or Capital Improvements in a

-109-

manner consistent with the Project Agreements and generally accepted practice in the electric utility industry, and the Participants shall advance the funds required to perform such Construction Work, Operating Work or Capital Improvements in accordance with the applicable provisions of the Project Agreements. The resolution of any dispute involving the failure of the Administrative Committee to reach agreement upon matters involving future expenditures shall have prospective application from the date of final determination, and the amounts advanced by the Participants pursuant to this Section 28 during the pendency of such dispute shall not be subject to refund except upon a final determination that the expenditures were not made in a manner consistent with the Project Agreements and generally accepted practice in the electric utility industry.

29. REMOVAL OF PROJECT MANAGER OR OPERATING AGENT

29.1 The Project Manager and Operating Agent shall serve during the term of and pursuant to this Participation Agreement unless either one resigns by giving written notice to the Participants at least one (1) year in advance of the date of resignation or until receipt by

-110-

either one of notice of its removal following a determination that it is in default of this Participation Agreement as provided in Section 29.2.2 hereof. Upon the effective date of such resignation or removal, the Participants shall designate a new Project Manager or Operating Agent by written agreement.

29.2 The following provisions shall apply solely in regard to violations or allegations of violations of this Participation Agreement by the Project Manager or the Operating Agent of a Component or Components of the Transmission System on the basis of which removal of either one is sought:

29.2.1 In the event any Participant shall be of the opinion that an action taken or not taken by the Project Manager or Operating Agent consititutes a violation of this Participation Agreement, it may give written notice thereof to the Project Manager or the Operating Agent as the case may be and the other Participants, together with a statement of the reasons for its opinion. Thereupon, the Project Manager or the Operating Agent may prepare a statement of the reasons justifying its action or

-111-

failure to take action. If agreement in settling the dispute is not reached between the Project Manager or the Operating Agent and the Participant which gave such notice, then the matter shall be submitted to arbitration in the manner provided in Section 27 hereof. During the continuance of the arbitration proceedings, the Project Manager or the Operating Agent may continue such action taken or not taken in the manner it deems most advisable and consistent with this Participation Agreement.

29.2.2 If it is determined by arbitration that the Project Manager or the Operating Agent is violating this Participation Agreement, then it shall act with due diligence to end such violation and shall, within six (6) months or within such lesser time following the determination as may be prescribed in the determination, take action or commence action in good faith to terminate such violation. In the event that the Project Manager or the Operating Agent has failed either to correct, or to commence action to correct, the violation within such allowed period (which itself may be a

-112-

subject of dispute for determination as above provided) it shall be deemed to be in default under this Participation Agreement and shall be subject to removal upon receipt of notice, executed by all the other Participants, in accordance with Section 29.1 hereof.

29.2.3 The provisions of Section 26 hereof shall not apply to disputes as to whether or not an action or non-action of the Project Manager or the Operating Agent, in its capacity as such, is a violation or a default under this Participation Agreement.

30. RELATIONSHIP OF PARTICIPANTS

30.1 The covenants, obligations and liabilities of the Participants are intended to be several and not joint or collective and nothing herein contained shall ever be construed to create an association, joint venture, trust or partnership, or to impose a trust or partnership covenant, obligation or liability on or with regard to any one or more of the Participants. Each Participant shall be individually responsible for its own covenants, obligations and liabilities as herein provided. No Participant or group of Participants shall be

-113-

33. UNCONTROLLABLE FORCES

33.1 No Participant shall be considered to be in default in the performance of any of its obligations under the Project Agreements (other than obligations of said Participant to pay costs and expenses) when a failure of performance shall be due to an uncontrollable force. The term “uncontrollable force” shall mean any cause beyond the control of the Participant affected, including but not restricted to failure of or threat of failure of facilities, flood, earthquake, tornado, volcanic eruption, storm, fire, lightning, epidemic, war, riot, civil disturbance or disobedience, labor dispute, labor or material shortage, sabotage, restraint by court order or public authority and action or non-action by or failure to obtain the necessary authorizations or approvals from any governmental agency or authority, which by exercise of due diligence such Participant could not reasonably

-115-

have been expected to avoid, and which by exercise of due diligence, it shall be unable to overcome. Nothing contained herein shall be construed so as to require a Participant to settle any strike or labor dispute in which it may be involved. Any Participant rendered unable to fulfill any of its obligations under the Project Agreements by reason of an uncontrollable force shall give prompt written notice of such fact to the other Participants and shall exercise due diligence to remove such inability with all reasonable dispatch.

37.4 Each term, covenant and condition of this Participation Agreement and the Project Agreements is deemed to be an independent term, covenant and condition, and the obligation of any Participant to perform any or all of the terms, covenants and conditions to be kept and performed by it is not dependent on the performance by the other Participants of any or all of the terms, covenants and conditions to be kept and performed by them.

40. EQUAL OPPORTUNITY

40.1 During the term of this Participation Agreement, the Project Manager and the Operating Agent (hereinafter in this Section 40 referred to collectively as the “Contractor”) agree as follows:

-122-

40.1.1 The Contractor shall not discriminate against any employee or applicant for employment because of race, color, religion, sex or national origin. The Contractor shall take affirmative action to ensure that applicants are employed and that employees are treated during employment without regard to their race, color, religion, sex or national origin. Such action shall include, but not be limited to, the following: employment, upgrading, demotion or transfer; recruitment or recruitment advertising; layoff or termination; rates of pay or other forms of compensation; and selection for training, including apprenticeship. The Contractor agrees to post in conspiciuous places, available to employees and applicants for employment, notices to be provided by the contracting officer setting forth the provisions of this non-discrimation clause.

40.1.2 The Contractor shall send to each labor union or representative of workers with which it has a collective bargaining agreement or other contract or understanding, a notice to be provided

-123-

advising the said labor union or workers’ representative of the Contractor’s commitments under this Section 40, and shall post copies of the notice in conspicuous places available to employees and applicants for employment.

40.1.3 The Contractor shall comply with all provisions of Executive Order 11246 of September 24, 1965, as amended by Executive Order 11375 of October 13, 1967, and the rules, regulations and relevant orders of the Secretary of Labor.

40.1.4 The Contractor shall furnish all information and reports required by Executive Order 11246 as amended by rules, regulations and orders of the Secretary of Labor, or pursuant thereto, and will permit access to its books, records and accounts by the administering agency and the Secretary of Labor for purposes of investigation to ascertain compliance with such rules, regulations and orders.

40.1.5 In the event of the Contractor’s non-compliance with the nondiscrimination clauses of this Participation Agreement or with any of the

-124-

said rules, regulations or orders, this Participation Agreement may be cancelled, terminated or suspended in whole or in part and the Contractor may be declared ineligible for further government contracts or federally assisted construction contracts in accordance with procedures authorized in said Executive Order 11246 as amended and such other sanctions may be imposed and remedies invoked as provided in the said Executive Order as amended or by rule, regulation or order of the Secretary of Labor, or as otherwise provided by law.

40.1.6 The Contractor shall include the provisions of Sections 40.1.1 through 40.1.7 hereof in every subcontract or purchase order unless exempted by rules, regulations or orders of the Secretary of Labor issued pursuant to Section 204 of said Executive Order 11246 as amended so that such provisions will be binding upon each subcontractor or vendor. The Contractor shall take such action with respect to any subcontract or purchase order as the administering agency may direct as a means of enforcing such provisions, including

-125-

sanctions for non-compliance; provided, however, that in the event the Contractor becomes involved in, or is threatened with, litigation with a subcontractor or vendor as a result of such direction by the administering agency, the Contractor may request the United States to enter into such litigation to protect the interests of the United States.

40.1.7 The Contractor shall, in all solicitations or advertisements for employees placed by or on behalf of the Contractor, state that all qualified applicants will receive consideration for employment without regard to race, color, religion, sex or national origin.

Pursuant to provisions of Title 42 U.S.C.A. 2000-e-2(i), the Contractor now has several agreements and contemplates it may have additional agreements with Indian Tribes providing for preference to qualified Indians for employment on the Reservation of such Indians. The Participants agree that the Contractor’s act of giving

-126-

preference to qualified Indians for employment on the Reservation of said Indians is not to be deemed inconsistent with the purposes or provisions of Section 40.1 hereof.

41. NOTICES

D.5 At the start of each calendar year, an estimated Payroll Tax Ratio, Benefits Ratio and Worker’s Compensation Ratio shall be used, and such ratios shall be determined in accordance with the methods set forth in Appendices F, G and H hereto, respectively. Such ratios shall be based on the Project Manager’s system-wide expenses for the preceding calendar year; provided, that by agreement of the Auditing Committee, such ratios may be adjusted to more nearly reflect the expenses of the current year because of legislation, labor contract negotiations or other factors not reflected in the

D-4

prior year’s costs.

D.6 As soon as practicable after the end of each calendar year, the actual Payroll Tax Ratio, Benefits Ratio and Worker’s Compensation Ratio for such year shall be determined in accordance with the methods set forth in Appendices F, G and H hereto, respectively, by using said year’s actual system-wide expenses of the Project Manager. Using said actual ratios, the portions of the Project Manager’s payroll tax expenses, employee worker’s compensation expenses, and employee pensions and benefit expenses for which the Participants are obligated hereunder for costs of Construction Work shall be determined for such year. To the extent that such expenses are more than or less than those already paid by the Participants during said year, the Project Manager shall xxxx or reimburse the Participants for the amount of such difference.

D.7 If any Participant believes that the application of or the method used in determining the Payroll Tax Ratio, Benefits Ratio or Worker’s Compensation Ratio results in an unreasonable burden on said Participant, that Participant may request that such application or method be submitted to the Auditing Committee for review; provided that such review shall not be requested prior to December 1, 1981, and thereafter at intervals of not less than two (2) years each. After any such request, subject to the time limitations set forth above, the Auditing Committee shall review such application or method and

D-5

shall endeavor to agree upon whether or not an unreasonable burden does actually exist. If after such review, the Auditing Committee determines that such application or method does result in an unreasonable burden on one or more of the Participants, the Auditing Committee shall determine and recommend a modified application or method to the Administrative Committee so that such unreasonable burden would be eliminated if such modified application or method is adopted by the Administrative Committee.

D.8 The Administrative Committee shall review the recommendations submitted by the Auditing Committee, and if, as a result of such review, the Administrative Committee agrees that such unreasonable burden does exist and that said modified application or method eliminates such unreasonable burden, then the Administrative Committee shall adopt said modified application or method. If the Auditing Committee has not submitted a recommendation and the Administrative Committee agrees that such unreasonable burden does exist, the Administrative Committee shall endeavor to agree on a modified application or method. If the Administrative Committee is unable to agree on any matter brought before it under this Section D.8, then any Participant may call for arbitration of such matter pursuant to Section 27 of the Transmission System Participation Agreement.

D.9 Any modified method adopted by the Administrative Committee or determined through arbitration shall be

D-6

retroactive to the first day of the month in which the unreasonable burden began except that the retroactive period can be no more than two (2) years from the date of the requested review. Said modified method shall stay in effect until a new modified method is approved, but in no event less than two (2) years from the date of such adoption or determination.

24.1 Except for any judgment debt for damage resulting from Willful Action and except to the extent any judgment debt is collectible from valid Project Insurance, and subject to the provisions of Sections 24.2, 24.4, 24.5 and 24.6 hereof, each Participant hereby extends to all other Participants, their directors, members of their governing bodies, officers and employees its covenant not to execute, levy or otherwise enforce a judgment obtained against any of them, including recording or effecting a judgment lien, for any direct, indirect or consequential loss, damage, claim, cost, charge or expense, whether or not resulting from the negligence of such Participant, its directors, members of its governing bodies, officers, employees, or any person or entity whose negligence would be imputed to such Participant from (i) Construction Work, Operating Work, the design and construction of Capital

- 6 -

Improvements, or the use of or ownership of the Transmission System or the Microwave System or (ii) the performance or nonperformance of the obligations of a Participant under the Project Agreements, other than the obligation to pay any monies which have become due.

24.2 In the event any insurer providing Project Insurance refuses to pay any judgment obtained by a Participant against another Participant, its directors, members of its governing bodies, officers or employees, on account of liability referred to in Section 24.1 hereof, the Participant, its directors, members of its governing bodies, officers or employees against whom the judgment is obtained shall, at the request of the prevailing Participant and in consideration of the covenant given in Section 24.1 hereof, execute such documents as may be necessary to effect an assignment of its contractual rights against the nonpaying insurer and thereby give the prevailing

- 7 -

Participant the opportunity to enforce its judgment directly against such insurer. In no event when a judgment debt is collectible from valid Project Insurance shall the Participant obtaining the judgment execute, levy or otherwise enforce the judgment (including recording or effecting a judgment lien) against the Participant, its directors, members of its governing bodies, officers or employees, against whom the judgment was obtained.

24.3 Except as provided in Sections 24.4, 24.5 and 24.6 hereof, the costs and expenses of discharging all Work Liability or liability resulting from the design or construction of Capital Improvements imposed upon one or more of the Participants for which payment is not made by Project Insurance shall be allocated among the Participants in proportion to their Cost Responsibility in the Components involved in the operative facts which give rise to the Work Liability or in proportion to their

- 8 -

Cost Responsibility for the Microwave System if such operative facts are associated with the Microwave System. However, if the proximate cause of such liability cannot be determined or is not related to any particular Component, then such costs and expenses shall be allocated among the Participants in proportion to their composite Cost Responsibility in the Transmission System as shown in Appendix B hereto.

24.4 Each Participant shall be responsible for any damage, loss, claim, cost, charge or expense that is not covered by Project Insurance and results from its own Willful Action as defined in Section 4.42.2 hereof and shall indemnify and hold harmless the other Participants, their directors, members of their governing bodies, officers and employees from any such damage, loss, claim, cost, charge or expense.

24.5 Except as provided in Section 24.4 hereof, the aggregate liability of any Participant to all other Participants

- 9 -

for Willful Action not covered by Project Insurance shall be determined as follows:

24.5.1 All such liability for damages, losses, claims, costs, charges or expenses of such Participant shall not exceed $1,000,000 per occurrence. Each Participant extends to each other Participant, its directors, members of its governing bodies, officers and employees its covenant not to execute, levy or otherwise enforce a judgment obtained against any of them for any such aggregate liability in excess of $1,000,000 per occurrence.

24.5.2 A claim based on Willful Action must be perfected by filing suit in a court of competent jurisdiction within three years after the Willful Action occurs. All claims made thereafter relating to the same Willful

- 10 -

Action shall be barred by this Section 24.5.2. The award to each nonwillfully acting Participant from each Participant determined to have committed Willful Action shall be determined as follows: (i) Each Participant who successfully files suit for remuneration shall receive the lesser of (a) its final judgment awarded (or settlement made) or (b) its pro-rata Cost Responsibility share (in the Component(s) involved in the operative facts which gave rise to the Willful Action) of the $1,000,000 maximum recovery established in Section 24.5.1 hereof; (ii) when all pending suits are resolved, those Participants who were awarded judgments or reached settlements but whose claims were not fully satisfied pursuant to Section

- 11 -

24.5.2(i) shall be entitled to participate in any remaining portion of the $1,000,000 maximum recovery limit, based upon the ratio of the unsatisfied portion of such Participant’s judgment or settlement to the total unsatisfied portion of all such judgments or settlements. Such participation shall be limited to the Participant’s unsatisfied judgments or settlements.

24.6 Except for liability resulting from Willful Action (which, subject to the provisions of Section 24.5 hereof, shall be the responsibility of the willfully acting Participant), any Participant whose electric customer shall have a claim or bring an action against any other Participant for any death, injury, loss or damage arising out of or in connection with electric service to such customer and caused by the operation or failure of operation of the Transmission System or Microwave System

- 12 -

or any portion thereof, shall indemnify and hold harmless such other Participant, its directors, members of its governing bodies, officers and employees from and against any liability for such death, injury, loss or damage.

24.7 The provisions of this Section 24 shall not be construed so as to relieve any insurer of its obligation to pay any insurance proceeds in accordance with the terms and conditions of valid and collectible Project Insurance policies.

24.8 The Participants agree that the aggregate liability limit of $1,000,000 referenced in Sections 24.5.1 and 24.5.2 hereof may be determined in the future to be inappropriate and shall make a good faith effort to evaluate, and if appropriate, revise said limit at the request of any Participant.”

4.3 Section 41.1 shall be deleted in its entirety and a new Section 41.1 shall be added as follows:

“41.1 Except as set forth in Section 41.2 hereof, any notice, demand or request provided for in this Participation Agreement or any other Project

- 13 -

Agreement shall be in writing and shall be deemed properly served, given or made if delivered in person or sent by registered or certified mail, postage prepaid, to the persons specified below.
