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 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(s) limits, eliminate coverage(s) or require additional policies not previously specified, and shall determine appropriate deductibles, retentions and other special terms and conditions of the Project Insurance.

- 74 -

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 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 High Voltage Switchyard 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

- 75 -

waive on behalf of each Participant its right of recovery against any such party for insured loss of or damage to any property covered by Project Insurance, provided that no such waiver shall impair the right to recover any sums otherwise payable to any Participant under the Project Insurance.

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

- 76 -

particularly set forth in Section 22 hereof. During any period of negotiations with an insurer, or other negotiations which are 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 or policies, which 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 or policies of Project Insurance.

23.10 Unless otherwise directed by the Administrative Committee, the Project Manager and Operating Agent shall obtain Project Insurance from such

- 77 -

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 on any Construction Insurance shall be allocated at the time of receipt thereof among the Participants in proportion to the funds advanced by each Participant for such Construction Insurance, 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 the funds advanced by each Participant for such policy.

23.12 Any refunds of premiums or dividends received by the Operating Agent on any Operating Insurance shall be allocated among the Participants in proportion to their Ownership Responsibility 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 Ownership Responsibility at such time.

- 78 -

23.13 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 bill the Participants on the basis thereof, with adjustment to be made when the dispute is resolved.

23.14 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 changes can be made and the effect thereof upon the coverage afforded each other Participant 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

- 79 -

afforded to any Participant, and (iii) will not result in any increase in premium expenses or if an increase in premium expenses 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 Administrative Committee for resolution.

23.15 Whenever there shall be nuclear fuel at the plant site of the Arizona Nuclear Power Project or in transit to or from said plant site, the Project Manager prior to the date of firm operation of the first generating unit of ANPP and the Operating Agent thereafter shall have in force and effect or cause to have in force and effect (i) Project Insurance in such minimum amount and in such form or forms as may be required from time to time by law, including the rules and regulations of the Nuclear Regulatory Commission and (ii) an indemnity agreement executed and delivered by the Nuclear Regulatory Commission as required by the Atomic Energy Act of 1954 as amended as of the date of this

- 80 -

Participation Agreement.

26.6 In addition to the remedies provided 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 High Voltage Switchyard may be operated economically and efficiently during periods when the defaulting Participant’s right to

- 90 -

receive its proportionate share of use of the High Voltage Switchyard 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 and a resolution is not reached pursuant to Sections 7.9 and 7.10 hereof, any Participant (s) may call for submission of the dispute to arbitration which shall be binding upon all of the 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

- 91 -

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, shall meet for the purpose of selecting arbitrators. Each Participant or group of Participants representing a 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

- 92 -

the American Arbitration Association, 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 appointment ·as an arbitrator who is or has ever been 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 laws, 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

- 93 -

information. The 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 with the dispute and relative to the materiality of the default, the period of time within which the defaulting Participant 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 judgment or other similar relief.

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

- 94 -

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 decision 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 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

- 95 -

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 subject to (i) resignation by giving written notice to the Participants at least one (1) year in advance of the date of resignation or (ii) 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 Toe 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 on the basis of which removal of either one is sought:

- 96 -

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 constitutes 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 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 has violated or 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

- 97 -

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 subject of dispute for determination as above provided) the Project Manager or the Operating Agent shall be deemed to be in default under this Participation Agreement and shall be subject to removal upon receipt of notice thereof 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

- 106 -

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.

- 107 -

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 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.

- 108 -

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.
