Except as provided in Section 10, PNM has a right of first refusal with respect to the proposed transfer of any ownership interest in the San Juan Project by any Party and TEP has a right of first refusal with respect to PNM’s proposed transfer of an interest in Unit 1 or Unit 2 and associated common property. The existence of other rights of first refusal shall be as provided in other appropriate instruments. Nothing in this Section 11 shall be construed to limit or expand the rights of first refusal of any Party.

11.2    Except as provided in Section 10, should a Party desire to assign, transfer, convey or otherwise dispose of (hereinafter collectively referred to as “Assign”) its rights, titles and interests in the San Juan Project, or its rights, titles and interests in, to and under the Project Agreements, or its rights, titles and interests in the water rights, lands, land rights or the improvements thereon or any part thereof or interest therein (hereinafter referred to as “Transfer Interest”), to any person, company, corporation or governmental agency (hereinafter referred to as “Outside Party”), the Party desiring to Assign shall first make an offer to sell the Transfer Interest to a Party(ies) having a right of first refusal, on the basis of the applicable amount as set out in either Section 11.2.1 or Section 11.2.2:

11.2.1    Where the Outside Party proposes to purchase for a specified monetary amount, from the Party desiring to Assign, an interest only in the San Juan Project and/or in contract rights, water rights, lands, land rights and improvements

49Restructuring Amendment 7/31/2015

EXECUTION VERSION

associated therewith, the amount of (i) a bona fide written offer from an Outside Party ready, willing and able (subject to obtaining any required regulatory approvals) to purchase the Transfer Interest; or, in the absence of a bona fide written offer, (ii) a purchase price set out in a bona fide purchase and sale agreement between the Party desiring to Assign and an Outside Party ready, willing and able (subject to obtaining any required regulatory approvals) to purchase the Transfer Interest; or

11.2.2    Where the Outside Party proposes to purchase from the Party desiring to Assign, (i) as part of a non-monetary offer (such as in the case of an asset swap) or (ii) when a segregated value for the Transfer Interest is not available (such as in the case of a bundled or packaged sale of assets), or (iii) where the Outside Party proposes to purchase an interest not only in the San Juan Project and/or in contract rights, water rights, lands, land rights and improvements associated therewith, but also in other property of the Party desiring to Assign, the purchase price shall be the fair market value of the Transfer Interest. As used herein, the term “fair market value” means the amount of money which a purchaser, willing but not obligated to buy the property, will pay to an owner, willing but not obligated to sell it, taking into consideration all of the uses to which the Transfer Interest is adapted and might in reason be applied.

Failure by a Party to serve notice as provided hereunder within the time period specified shall be conclusively deemed to be notice of its intention not to purchase the Transfer Interest.

11.5    When intention to purchase the entire Transfer Interest has been indicated by notices duly given hereunder by the Party(ies) desiring to purchase the Transfer Interest, the affected Parties shall thereby incur the following obligations:

The purchase of the Transfer Interest shall be fully consummated within six (6) months following the date upon which all notices required to be given under this Section 11 have been duly served, unless the Party is then diligently pursuing applications to appropriate regulatory bodies (if any) for required authorizations to effect such assignment or is then diligently prosecuting or defending appeals from orders entered or authorizations issued in connection with such applications.

11.6    If the intention to purchase the entire Transfer Interest has not been indicated by notices given within the time periods specified in this Section 11 by a Party desiring to purchase the Transfer Interest, the Party desiring to Assign shall be free to Assign all, but not less than all, of its Transfer Interest to the Outside Party that made the Outside Offer, upon the terms and conditions set forth in the Outside Offer. If such assignment of the entire Transfer Interest to the Outside Party is not completed within three (3) years after the approximate proposed date to Assign specified in the notice given pursuant to Section 11.3, the Party desiring to Assign its Transfer Interest must, unless it is then diligently pursuing its applications to appropriate regulatory bodies (if any) for required authorizations to effect

11.7    No assignment of a Transfer Interest, whether to another Party or to an Outside Party, shall relieve the assigning Party from full liability and financial responsibility for performance after any such assignment: (i) of all obligations and duties incurred by such Party prior to such assignment under the terms and conditions of the Project Agreements; and/or (ii) of all obligations and duties provided and imposed after such assignment upon such assigning Party under the terms and conditions of the Project Agreements, unless and until the assignee shall agree in writing with the remaining Parties to assume the obligations and duties of a Party hereunder; provided further, however, that such assignor shall not be relieved of any of its obligations and duties by an assignment under this Section 11, without the express prior written consent of the remaining Parties, which consent shall not be unreasonably withheld.

11.8    Any transferee, successor or assignee, or any party who may succeed to the Transfer Interest pursuant to this Section 11, shall specifically agree in writing with the remaining Parties at the time of such transfer or assignment that it will not transfer or assign all or any portion of the Transfer Interest so acquired without complying with the terms and conditions of this Section 11.

11.10    A Party may, for the purpose of financing its interest in pollution control systems and facilities at the San Juan Project, sell, transfer or convey such interests pursuant to the New Mexico Pollution Control Revenue Bond Act, and any such sale, transfer or conveyance shall not be deemed as an assignment, transfer, conveyance or other disposal within the meaning of this Section 11.

22.6    Payroll loads for administrative and general expenses, payroll taxes, injuries and damages and pension and benefits, shall be added to the monthly billings in proportion to the dollars of direct labor billed and apportioned among the Participants in accordance with Sections 22 and 23. The current methodologies for calculating the A&G Ratio, Payroll Tax Ratio, Injuries and Damages Ratio and Pension and Benefits Ratio are set forth in Exhibit VI (Attachments A, B, C and D thereto), attached hereto and incorporated herein.

22.6.1    If any Participant believes that the method used in determining A&G Ratio, Payroll Tax Ratio, Injuries and Damages Ratio and Pension and Benefits Ratio, in accordance with Exhibit VI (Attachments A, B, C and D thereto), results in an unreasonable burden on such Participant(s), such Participant(s) may request that said method used in determining said ratios be submitted to the Auditing Committee for review. After any such request, the Auditing Committee shall review said method and shall endeavor to agree upon whether or not said unreasonable burden does actually exist. If, after such review, the Auditing Committee determines that the application of said method does result in an unreasonable burden on the Participant, the Auditing Committee shall determine and recommend a modified

EXECUTION VERSION

method to the Coordination Committee to eliminate such unreasonable burden. If, after such review, the Auditing Committee is unable to agree upon whether or not such unreasonable burden does exist or is unable to agree on a modified method for eliminating said unreasonable burden, the Auditing Committee shall submit the entire matter to the Coordination Committee.

22.6.2    The Coordination Committee shall review the recommendation of the Auditing Committee pursuant to Section 22.6.1. If, as a result of such review, the Coordination Committee agrees that such unreasonable burden does exist and that a modified method eliminates such unreasonable burden, the Coordination Committee shall adopt said modified method.

22.6.3    If the Auditing Committee has not submitted a recommended modified method and the Coordination Committee agrees that such unreasonable burden does exist, the Coordination Committee shall endeavor to agree on a modified method. If, after such review, the Coordination Committee is unable to agree that such unreasonable burden does exist or on a modified method which will eliminate such unreasonable burden, upon request of a Participant, either matter may be submitted to arbitration pursuant to Section 37.

22.7    As soon as possible after the end of each calendar year, the Operating Agent shall calculate the actual ratios for: A&G, payroll tax, injuries and damages, and pension and benefits for such year in accordance with the methodologies described in Exhibit VI (Attachments A, B, C and D thereto). To the extent such expenses are more or less than those already paid by the Participants during said year, the Operating Agent shall bill or credit the Participants for the amount of such difference.

22.8    At the start of each calendar year, the Operating Agent shall calculate new ratios for: A&G, payroll tax, injuries and damages and pension and benefits. Such ratios shall be calculated in accordance with the methodologies described in Exhibit VI (Attachments A, B, C and D thereto). Such ratios may be adjusted to more nearly reflect the anticipated expenses of the current year because of tax legislation, labor contract negotiations or other factors not reflected in the prior year’s costs.

22.9    The Operating Agent shall bill to the requesting Party(ies) the costs and expenses, including A&G expenses, incurred by the Operating Agent (including, but not limited to, fees of outside legal counsel or consultants, time of in-house legal counsel and other employees and agents of the Operating Agent) in performing tasks requested by a Party in relation to (i) the offering or sale of bonds or other type of security by a Party in connection with the acquisition or ownership of an interest in the San Juan Project; and (ii) the attempted or contemplated sale by a Party of any portion of its ownership interest in the San Juan Project.

94Restructuring Amendment 7/31/2015

EXECUTION VERSION

“Interim Invoices”, “UG-CSA Invoices”, and “UPS Invoices” prepared and defined pursuant to Section 8 of the Underground Coal Sales Agreement.

23.4    Monthly costs of the Project Coal Inventory and fuel expense shall be apportioned among and paid for by the Participants on the following basis:        

23.4.1    UG-CSA Invoicing Allocations

In the event that UG-CSA Invoices are rendered and payable pursuant to Section 8.7 (A) of the Underground Coal Sales Agreement, amounts due thereunder shall be allocated and paid for by the Participants as Fixed Fuel Expense and Variable Fuel Expense as described in: Exhibit IX, Fixed Fuel Expense; and Exhibit X, Variable Fuel Expense and as provided below:

23.4.1.1    Costs that are classified as Fixed Fuel Expense shall be charged to FERC Account 501, or to such FERC Account number as may be applicable in the future if fuel deliveries terminate, and shall be apportioned among and paid for by the Participants in accordance with Common Participation Share.

23.4.1.2    Costs that are classified as Variable Fuel Expense shall be charged to FERC Account 151 and such costs shall be apportioned among and paid for by the Participants on the basis of Common Participation Share. Monthly cost for coal withdrawn from Project Coal Inventory (equivalent to total monthly Participant Coal Consumption) shall be credited to FERC Account 151 and charged to FERC Account 501 on an

95Restructuring Amendment 7/31/2015

EXECUTION VERSION

average price basis as determined by dividing the total number of tons of coal in Project Coal Inventory at the beginning of the month, plus the coal delivered during the month, into the total recorded cost in FERC Account 151 and multiplying the cost per ton so derived by the number of tons withdrawn. The cost for coal withdrawn charged to FERC Account 501 shall be apportioned among and paid for by the Participants on the basis of the percentage that each Participant’s monthly Participant Coal Consumption bears to the total monthly Participant Coal Consumption of all Units. The cost for coal withdrawn thusly credited to FERC Account 151 shall be apportioned among the Participants on the basis of Common Participation Share.

23.4.1.3    Any other Total Monthly Coal Cost not currently classified in Exhibits IX or X as Fixed Fuel Expense or Variable Fuel Expense shall be deemed to be Fixed Expense until reclassified by the Coordination Committee.

23.4.2        Interim Invoicing Allocations

In the event that Interim Invoices are rendered and payable pursuant to Section 8.7 (B) of the Underground Coal Sales Agreement, such costs shall be allocated and invoiced to the Participants as described below.

23.4.2.1    The Base Price (“Base Price”) band shall be based on the Minimum Annual Tons. The annual allocation of the coal tonnage

96Restructuring Amendment 7/31/2015

EXECUTION VERSION

in the Base Price band shall be made among the Participants on the basis of Common Participation Share. The monthly allocation of the coal tonnage in the Base Price band shall be made among the Participants on the basis of each Participant’s share of Monthly Minimum Tons. The cost of the monthly Base Price band will be allocated among and paid for by the Participants by multiplying each Participant’s share of Monthly Minimum Tons by the Base Price.

23.4.2.2    The Incremental Price (“Incremental Price”) band(s) shall be based on (an) annualized band(s) of tons of coal delivered in excess of Minimum Annual Tons. The cost of the monthly Incremental Price band(s) will be allocated among and paid for by the Participants by multiplying each Participant’s consumption of Incremental Price band coal(s) by the Incremental Price for such band(s). Participants shall only be eligible for allocation of Incremental Price band coal pricing if their monthly Participant Coal Consumption exceeds their share of Monthly Minimum Tons.

23.4.2.3    At the end of each year, the Operating Agent shall reconcile the sum of each Participant’s monthly Interim Invoice-related payments to a properly allocable share of Base Price band tons, Incremental Price band or bands tons, and cost associated with any change in Project Coal Inventory and invoice or refund any such reconciliation

97Restructuring Amendment 7/31/2015

EXECUTION VERSION

amounts to each Participant. This reconciliation will be exclusive of any year-end true up required pursuant to Section 23.4.2.6.

23.4.2.4    In the year-end reconciliation process of Section 23.4.2.3, any amount credited by SJCC for tons invoiced but not delivered shall be credited to FERC Account 501 and apportioned to the Participants on the basis of the percentage that each Participant’s annual Incremental Price Band(s) consumption bears to the total annual Incremental Price Band(s) consumption for all Units. Any net consumption of Project Coal Inventory tons shall be charged to FERC Account 501 and apportioned among and paid for by the Participants on the basis of the percentage that each Participant’s annual Incremental Price Band(s) consumption bears to the total annual Incremental Price Band(s) consumption for all Units. The price for such tons shall be determined by dividing the total recorded cost in FERC Account 151 by the total number of tons of coal in Project Coal Inventory, both as recorded on January 1 of said year. The total amount of any such payment for consumed Project Coal Inventory tons shall subsequently be credited to FERC Account 151 and apportioned to the Participants based on Common Participation Share.

In the year-end reconciliation process of Section 23.4.2.3, the costs of any net addition to Project Coal Inventory tons, as invoiced by SJCC, shall be

98Restructuring Amendment 7/31/2015

EXECUTION VERSION

charged to FERC Account 151 and apportioned to and paid for by the Participants based on Common Participation Share.

23.4.2.5    If, at the end of any year, the Operating Agent has collected amounts in excess of those due S JCC pursuant to Section 8.7(B) of the Underground Coal Sales Agreement, but not including any year-end true up required pursuant to Section 23.4.2.6, such over-collection shall be refunded to the Participants. The refund to each Participant shall be an amount equal to the total amount of the over-collection multiplied by the tons each Participant’s Coal Consumption was less than its total annual Monthly Minimum Tons divided by the total amount by which all such Participants’ Coal Consumption was less than their shares of Minimum Annual Tons.

23.4.2.6    The Interim Invoices shall be annually reconciled to invoices prepared pursuant to Section 8.7(A) of the Underground Coal Sales Agreement. Any adjustment required by this reconciliation, in accordance with Section 8.7(B) of the Underground Coal Sales Agreement, will be passed through to the Participants as correcting invoices and will be apportioned among and paid for by, or credited to, the Participants on the basis of Common Participation Share.

23.4.2.7    Monthly UPS payments shall be apportioned among and paid for by the Participants on the basis of Common Participation Share

23.4.2.8    Any other component of Total Monthly Coal Cost which is not classified as Base Price or Incremental Price shall be apportioned among and paid for by the Participants on the basis of Common Participation Share unless otherwise annually approved by the Fuels Committee.

23.4.2.9    If during any year, payable Interim Invoices cease to be rendered by SJCC pursuant to Section 8.7(B) of the Underground Coal Sales Agreement, the Participants acknowledge and recognize that Interim Invoicing cannot be in effect for a partial year, and that all allocations of Total Monthly Coal Costs for the year shall then be made pursuant to Section 23.4.1. Amounts previously allocated to the Participants pursuant to Section 23.4.2 in the affected year shall be reallocated pursuant to the provisions of Section 23.4.1.

23.4.2.10    The Fuels Committee may terminate allocation of costs to the Participants pursuant to Section 23.4.2 despite the continued receipt of payable Interim Invoices from SJCC, if the Fuels Committee determines that coal cost allocation pursuant to Section 23.4.1 better serves the interests of the San Juan Project. Such termination may only be made

100Restructuring Amendment 7/31/2015

EXECUTION VERSION

upon action of the Fuels Committee pursuant to Section 20.5. In the event of such termination, costs shall continue to be apportioned to and paid for by the Participants pursuant to Section 23.4.2. However, for information purposes, the Operating Agent shall also provide cost allocations to the Participants pursuant to Section 23.4.1. At the end of such year, the amounts paid by the Participants shall be reconciled to those amounts allocated pursuant to Section 23.4.1 for each month of the affected year (Section 23.4.1 allocations being determinative) and the Operating Agent shall invoice or refund any such reconciliation amounts to each Participant.

23.5    Limestone costs (chemicals) chargeable to FERC Account 502 shall be apportioned among and paid for by the Participants on the basis of the percentage that each Participant’s monthly Participant Coal Consumption bears to the total monthly Participant Coal Consumption of all Units.

23.6    All other fuel-related expenses which are chargeable to FERC Account 501 shall be apportioned among and paid for by the Participants on the following basis:

23.6.1    Variable fuel-related expenses (including, but not limited to ash and gypsum disposal) on the basis of the percentage that each Participant’s monthly Participant Coal Consumption bears to the total monthly Participant Coal Consumption of all Units.

23.6.3    Fuel oil purchased for use at the San Juan Project is first delivered into one of two storage tanks. Tank 1 and 2 storage tank feeds Units 1 and 2 and Tank 3 and 4 storage tank feeds Units 3 and 4. When oil is withdrawn from a storage tank for consumption, it is metered by Unit. Costs for fuel oil usage shall be separately accounted for by these two storage tanks as follows:

23.6.3.1    Costs for fuel oil purchases to Tank 1 and 2 shall be charged to FERC Account 151 and such costs shall be apportioned among and paid for by the Units 1 and 2 Participants on the basis of Section 6.2.4. Monthly cost for fuel oil withdrawn from Tank 1 and 2 shall be credited to FERC Account 151 and charged to FERC Account 501 on an average price basis as determined by dividing the total number of gallons of fuel oil in Tank 1 and 2 at the beginning of the month, plus the fuel oil delivered during the month, into the total recorded cost in FERC Account 151 and multiplying the cost per gallon so derived by the number of gallons withdrawn from Tank 1 and 2. The cost for fuel oil withdrawn from Tank 1 and 2 charged to FERC Account 501 shall be apportioned among and paid for by the Units 1 and 2 Participants first on the basis of the individual Unit metered consumption and then on the basis of Section 6.2.1. The cost for fuel oil withdrawn from Tank 1 and 2 thusly credited to FERC Account 151 shall be apportioned among the Units 1 and 2 Participants on the basis of Section 6.2.4.

23.6.3.2    Costs for fuel oil purchases to Tank 3 and 4 shall be charged to FERC Account 151 and such costs shall be apportioned among and paid for by the Units 3 and 4 Participants on the basis of Section 6.2.5. Monthly cost for fuel oil withdrawn from Tank 3 and 4 shall be credited to FERC Account 151 and charged to FERC Account 501 on an average price basis as determined by dividing the total number of gallons of fuel oil in Tank 3 and 4 at the beginning of the month, plus the fuel oil delivered during the month, into the total recorded cost in FERC Account 151 and multiplying the cost per gallon so derived by the number of gallons withdrawn from Tank 3 and 4. The cost for fuel oil withdrawn from Tank 3 and 4 charged to FERC Account 501 shall be apportioned among and paid for by the Units 3 and 4 Participants first on the basis of the individual Unit metered consumption and then on the basis of Section 6.2.2 or Section 6.2.3, as applicable. The cost for fuel oil withdrawn from Tank 3 and 4 thusly credited to FERC Account 151 shall be apportioned among the Units 3 and 4 Participants on the basis of Section 6.2.5.

23.7    The Operating Agent shall provide the Participants a monthly written report on the following items related to coal deliveries at the San Juan Project:

23.10    The monthly costs of fuel allocated among the Participants in accordance with this Section 23 shall be estimated by the Operating Agent as soon as practicable after the end of each month and a preliminary bill shall be presented and paid in the manner set forth in Section 30.3.3. Adjustments and corrections to the estimated preliminary bill shall be made in the next succeeding month or on the earliest possible billing thereafter.

23.11    In the event of a catastrophic occurrence which results in a sustained outage of a Unit and a determination that an “Uncontrollable Force” exists under the CSA, then in such event, FERC Account 151 will be allocated to the operable and non-operable Units. The portion of FERC Account 151 allocated to the non-operable Unit(s) shall remain frozen until such time as such Unit(s) is restored to operable condition. New costs of coal chargeable to FERC Account 151 will be apportioned among the Participants on the basis of the Participants’ Participation Shares in the generating capacity of the operable Units. At such time as a damaged Unit is restored to operable condition, the frozen portion of Account 151 will be merged into the operable unit(s) portion of Account 151 and to the extent that a Participant is adversely impacted by an incremental increase in the average unit cost of coal an allocation of such incremental cost will be made and the net difference paid by the Participant having a credit balance.

23.12    The accounting practices and billing and accounting principles as stated in this Section 23 are applicable at the present time. If, however, at a later time these practices or principles are proven to be inadequate or other practices or principles later prove to be more equitable in the opinion of the Auditing Committee, the Coordination Committee,

105Restructuring Amendment 7/31/2015

EXECUTION VERSION

upon the recommendation of the Auditing Committee, may authorize changes and revisions to such practices and principles.

23.13    Any other fuel-related costs not currently classified in this Section 23 shall be apportioned among and paid for by the Participants on the basis of the percentage that each Participant’s monthly Participant Coal Consumption bears to the total monthly Participant Coal Consumption of all Units until classified by the Coordination Committee.         23.14 Notwithstanding the provisions of Sections 23.1 through 23.13, beginning on January 1, 2016, PNM will supply coal to (i) the Exiting Participants under the provisions of Sections 23.15 through 23.17; and (ii) the Remaining Participants under the provisions of Section 23.18. PNM will have all cost obligations under the CSA for coal supplied to the Exiting Participants and PNM will have all rights to the Exiting Participants’ inventory relinquished to PNM under Section 23.15.

23.15    The Exiting Participants will relinquish to PNM their Common Participation Shares of Shared Coal Inventory that exist as of January 1, 2016, at the following values: $16.88/ton for coal tons stockpiled on SJCC’s property and $22.69/ton for coal tons stockpiled on the SJGS plant site. The total sum paid by PNM for Common Participation Shares of Shared Coal Inventory will be allocated as follows:

23.15.1    M-S-R            32.22%

23.15.2    Anaheim         11.48%

23.15.3    SCPPA            47.08%

23.15.4    Tri-State         9.22%

106Restructuring Amendment 7/31/2015

EXECUTION VERSION

$50/ton in 2016 and 2017. This $50/ton covers all payment obligations for coal supplied to the Exiting Participants that might otherwise be due under (i) the Restructuring Agreement; (ii) the CSA, including Legacy Costs, taxes and royalties; and (iii) gross receipts taxes under the Refined Coal Supply Agreement or otherwise. This $50/ton does not include payments for reclamation costs under the RSA or disposal costs under the CCRDA.

23.17 Exiting Participants will not have any take-or-pay or minimum purchase obligations under the CSA; provided, however, the Exiting Participants must comply with the following dispatch requirements. The Exiting Participants will dispatch their respective shares of the Units to no less than their Minimum Annual Generation. The Exiting Participants will be billed monthly based on their Participant Coal Consumption. At the end of each of 2016 and 2017, any Exiting Participant that has not met its Minimum Annual Tonnage Purchase Obligation will be billed at $50/ton for the difference between its actual Participant Coal Consumption and its Minimum Annual Tonnage Purchase Obligation; provided, in the event that at any time during 2016 or 2017 PNM is unable to supply coal to the Exiting Participants as provided in Section 23.16, then the Minimum Annual Tonnage Purchase Obligation will be proportionately reduced to account for any such period of time in which PNM is unable to supply coal.

23.18    For purposes of the calculations in this Section 23.18, PNM’s Common Participation Share will include the Exiting Participants’ Common Participation Share, and PNM’s Participant Coal Consumption will include the Exiting Participants’

23.18.1 Pre-existing Stockpile Coal tons as invoiced by SJCC will be allocated by a Remaining Participant’s Common Participation Share as of the Effective Date and will be paid for by each Remaining Participant at the price per ton charged by SJCC in its monthly invoicing to PNM.

23.18.2 Each year, PNM will develop a monthly Tier 1 Tonnage Allocation schedule with SJCC in the annual operating plan process as provided for in Section 7.2 of the CSA. With input from the Remaining Participants, PNM will develop a monthly allocation by Remaining Participant of such Tier 1 Tons (such individual allocation, its “Tier 1 Tonnage Allocation”). Such monthly Tier 1 Tonnage Allocation will be paid for by Remaining Participants whether or not their Participant Coal Consumption exceeded their Tier 1 Tonnage Allocation in the month. Monthly, for each Remaining Participant, its Tier 1 Tonnage Allocation, net of its invoiced Pre-existing Stockpile Coal for such month will be paid for at the then existing price for Tier 1 Tons under the CSA. In each of 2016 and 2017, five million six hundred thousand (5,600,000) tons will be allocated by Remaining Participant Share, and then PNM will be allocated an additional one hundred fifty thousand (150,000) tons in each of those years.

23.18.8 In the event of an SJCC environmental force majeure, then Available Pre-existing Stockpile Tons will be allocated in the same manner as Pre-existing Stockpile Coal tons, and Force Majeure Tons will be allocated in the same manner as Tier 1 Tons unless otherwise approved by the Remaining Participants in the Fuels Committee. Such calculations will be on an annual basis.

23.18.9 Any other costs billed by SJCC under the CSA and not specifically addressed in this Section 23.18 will be apportioned among and paid for by the Remaining Participants on the basis of the Remaining Participant’s Common Participation Share for that year unless otherwise annually approved by the Remaining Participants in the Fuels Committee.

23.18.10 Annual Year-End Reconciliation Process.    

23.18.10.1 At the end of each year, the Operating Agent will reconcile the sum of each Remaining Participant’s monthly CSA-related payments to a properly allocable share of annual Tier 1 Tons, Tier 2 Tons, Pre-existing Stockpile Coal tons, and cost associated with any change in Project Coal Inventory and invoice or refund any such reconciliation amounts to each Remaining Participant.

23.18.10.2 Any net consumption of Project Coal Inventory tons will be charged to FERC Account 501 and apportioned among and paid for by the Remaining Participants on the basis of the percentage that each Remaining Participant’s annual Tier 2 Tons after the reconciliation

110Restructuring Amendment 7/31/2015

EXECUTION VERSION

process bears to the total annual Tier 2 Tons consumption after the reconciliation process for all Units. The price for such tons will be determined by dividing the total recorded cost in FERC Account 151 by the total number of tons of coal in Project Coal Inventory, both as recorded on January 1 of said year. The total amount of any such payment for consumed Project Coal Inventory tons will subsequently be credited to FERC Account 151 and apportioned to the Remaining Participants based on the Remaining Participant’s Common Participation Share for that year.

23.18.10.3 The costs of any net addition to Project Coal Inventory tons, as invoiced by SJCC, will be charged to FERC Account 151 and apportioned to and paid for by the Remaining Participants based on the Remaining Participant’s Common Participation Share for that year.

23.18.10.4 If, at the end of any year, the Operating Agent has collected amounts in excess of those due SJCC under the CSA, such over-collection will be refunded to the Remaining Participants. The refund to each Remaining Participant will be an amount equal to the total amount of the over-collection multiplied by the tons each Remaining Participant’s Coal Consumption was less than its total annual Tier 1 Tonnage Allocation divided by the total amount by which all such Remaining Participants’ Coal Consumption was less than their Tier 1 Tonnage Allocation.

33.0    REMOVAL OF OPERATING AGENT:

33.1    The Operating Agent shall serve as such during the term of this Agreement unless it resigns as Operating Agent by giving notice to the Parties at least one (1) year in advance of the date of resignation or until receipt by the Operating Agent of notice of its removal as provided in Section 33.2.

33.2    The Operating Agent may be removed as Operating Agent for any one of the following reasons:

33.2.1    The Operating Agent may be removed by action of the Coordination Committee if, in the judgment of the Coordination Committee (voting as provided for in Section 18.4), the best interests of the San Juan Project require that a new Operating Agent be selected. Any Party seeking a Coordination Committee determination to remove the Operating Agent shall provide to the Operating Agent and to all of the Parties a written statement, detailing the reasons why, in the judgment of the initiating Party, the Operating Agent should be removed. Within thirty (30) days after receipt by the Operating Agent of this written statement, the Operating Agent shall prepare and serve upon all of the Parties its response which shall contain a detailed rebuttal of the allegations made in the initiating statement. Within the same thirty (30) day period, any other Party may also prepare and serve upon the Operating Agent and the Parties a statement responding to the allegations in the initiating statement. Within twenty (20) days after service of all such response statements, the Coordination Committee shall meet to consider what

EXECUTION VERSION

action, if any, to take with regard to the removal of the Operating Agent. If, pursuant to this Section 33.2.1, the Coordination Committee removes the Operating Agent, such removal shall be effective upon the date established by the Coordination Committee. If the Operating Agent or any Party is dissatisfied with the action of the Coordination Committee, it shall have the right to seek arbitration under Section 37, but no demand for arbitration shall stay the decision of the Coordination Committee to remove the Operating Agent.

33.2.2    If, pursuant to the provisions of Section 34, it is determined that the Operating Agent is in default of its obligations under this Agreement, the Operating Agent may be removed by written notice given by any Party under Section 34.1.2, which notice shall state the effective date of the removal of the Operating Agent.

EXECUTION VERSION

34.0    DEFAULTS BY OPERATING AGENT:

34.1    The following provisions shall apply solely in regard to violations or allegations of violations of this Agreement by the Operating Agent on the basis of which removal of the Operating Agent is sought:

34.1.1    In the event any Party shall be of the opinion that an action taken or failed to be taken by the Operating Agent constitutes a violation of this Agreement, it may give written notice thereof to the Operating Agent and the other Parties, together with a statement of the basis for its opinion. Thereupon, 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 Operating Agent and such Party which gave such notice, then the matter shall be submitted to arbitration in the manner provided in Section 37. During the continuance of the arbitration proceedings, the Operating Agent may continue such action taken or failed to be taken in the manner it deems most advisable and consistent with this Agreement.

34.1.2    If it is determined that the Operating Agent is violating this Agreement, then the Operating Agent shall act with due diligence to end such violation and shall, within thirty (30) days 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 complaining

Party is of the opinion that the Operating Agent has not taken such action to correct,

EXECUTION VERSION

or to commence action to correct, the violation within such allowed period, the complaining Party shall be entitled to submit the question of the Operating Agent’s good faith action to terminate such violation to arbitration as provided in Section 37.

34.1.3    The provisions of Section 35, excepting Sections 35.8 and 35.9, shall not apply to disputes as to whether or not an action or non-action of the Operating Agent, in its capacity as Operating Agent, is a violation or default under this Agreement.

PART VII

DEFAULTS, LIABILITY AND ARBITRATION

35.    DEFAULTS:

35.1    Each Party shall pay all monies and carry out all other performances, duties and obligations agreed to be paid or performed by it pursuant to all of the terms and conditions set forth and contained in the Project Agreements, and a default by any Party in the covenants and obligations to be by it kept and performed pursuant to the terms and conditions set forth and contained in any of the Project Agreements shall be an act of default under this Agreement. A default under the Mine Reclamation Agreement or the Decommissioning Agreement is not a default under this Agreement. If a Party breaches a performance obligation under Sections 4.3 or 5 of the Restructuring Agreement, which provisions are incorporated in Sections 7.13.1 and 23 of this Agreement, the non-defaulting Parties’ remedies shall be as provided in this Agreement. A default under any other section of the Restructuring Agreement shall not be a default under this Agreement, irrespective of whether it is incorporated in this Agreement, and remedies for such a default shall be as provided in the Restructuring Agreement.

35.2    In the event of a default by a Party in any of the terms and conditions of this Agreement to be performed by that Party, the following shall apply:

35.2.1    The Operating Agent shall give a written notice of the default to the defaulting Party and the other Parties in accordance with Section 35.2.2.

141Restructuring Amendment 7/31/2015

EXECUTION VERSION

35.2.2    The notice of default shall specify the existence, nature and extent of the default. Upon receipt of the notice of default, the defaulting Party shall immediately take all steps necessary to cure the default as promptly and completely as possible.

35.3    In the event that any Party shall dispute an asserted default by it, then such Party shall pay the disputed payment or perform the disputed obligation, but may do so under protest. The protest shall be in writing, shall accompany the disputed payment or precede the performance of the disputed obligation(s), and shall specify the reason upon which the protest is based. Copies of such protest shall be mailed by such Party to all other Parties and to the Operating Agent. Payments not made under protest shall be deemed correct, except to the extent that periodic or annual audits may reveal over or under payment by a Party or may necessitate adjustments. In the event it is determined by arbitration, pursuant to the provisions of this Agreement or otherwise, that the protesting Party 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 Party(ies) shall reimburse such amount to the protesting Party, together with interest thereon at the rate of ten percent (10%) per annum, or the maximum legal rate of interest, whichever is lesser, from the date of payment or of the performance of a disputed obligation to the date of reimbursement.

142Restructuring Amendment 7/31/2015

EXECUTION VERSION

35.4    In the event a default shall continue for a period of ten (10) days or more after the notice given by the Operating Agent in accordance with Section 35.2 without having been cured by the defaulting Participant, or without such defaulting Party having commenced or continued action in good faith to cure such default, the following shall apply:

35.4.1    If the defaulting Party has failed to cure such default or to commence such good faith action during said ten (10) day period, the Operating Agent shall make a written report to the Engineering and Operating Committee concerning the status of the default and shall, on the next working day after such ten (10) day period, notify the defaulting Party in writing that the Operating Agent intends to declare the defaulting Party in default under the Project Agreements unless there is a prompt cure of the default. Seven (7) days after the giving of such notice to the defaulting Party, the Operating Agent shall make a second written report to the Engineering and Operating Committee concerning the status of the default and the efforts, if any, of the defaulting Party to cure the default. If, within seven (7) additional days, the defaulting Party has neither cured nor reasonably commenced to cure the default, the Operating Agent shall declare the defaulting Party in default under the Project Agreements and shall provide written notification of the declaration of default to the defaulting Party and to the Engineering and Operating Committee. Thereafter, and for so long as the default is not remedied and the declaration of default is not revoked by the Operating Agent, all rights of the

143Restructuring Amendment 7/31/2015

EXECUTION VERSION

defaulting Party under the Project Agreements shall be suspended, including the right to vote on all committees and to receive all or any part of its proportionate share of the Net Effective Generating Capacity.

35.4.2    Within seventeen (17) days after the notice by the Operating Agent, as provided for in Section 35.2, the Operating Agent shall prepare special operating procedures for approval by the Engineering and Operating Committee that will apply during the period of suspension under Section 35.4.1. Upon approval by the Engineering and Operating Committee, the Operating Agent shall provide notice to each Party of such special procedures. These special procedures shall include:

35.4.2.1    A tabulation in form similar to Section 6.2 of the percentages of costs to be borne by the non-defaulting Parties pursuant to Section 35.5;

35.4.2.2    Billing and accounting of such costs;

35.4.2.3    Dispatch and scheduling of the defaulting Party’s proportionate share of Net Effective Generating Capacity; and

35.4.2.4    Any other items required for the optimal use of the San Juan Project and the mitigation of damages by the non-defaulting Parties.

35.4.2.5    If the Operating Agent proposes to broker all or a portion of the defaulting Party’s proportionate share of Net Effective Generating Capacity on behalf of one or more non-defaulting Parties, the form of such an agreement shall be incorporated in such procedures.

144Restructuring Amendment 7/31/2015

EXECUTION VERSION

35.4.3    Within twenty (20) days after the declaration of a default, as provided for in Section 35.4.1, the defaulting Party and the non-defaulting Parties shall convene a meeting to address the defaulting Party’s situation and its intentions with regard to curing its default. The defaulting Party shall promptly prepare a cure plan for approval by the members of the Coordination Committee entitled to vote thereon. The cure plan shall address the defaulting Party’s plan to cure the default and restore itself to full participation as an owner of the San Juan Project. The Coordination Committee, by vote of the members of the Coordination Committee entitled to vote thereon, will monitor the defaulting Party’s compliance with the terms and conditions of the cure plan and if it appears to the Coordination Committee that the defaulting Party is or will be unable to comply with the terms of an approved cure plan, the Coordination Committee shall consider what actions may be required to address such inability, including, but not limited to, directing the Operating Agent to take such actions as may be appropriate. It is the intent of the Parties that any defaults shall be cured on as expeditious a basis as reasonably possible.

35.4.4    A demand for arbitration of an asserted default pursuant to Section 37 shall not stay the suspension of the rights of the defaulting Party, but in the event that the board of arbitrators shall determine that the asserted default did not in fact exist or occur, the arbitrators shall specify a method of fully and fairly compensating the Party which, under Section 35.4.1, was denied the right to vote on committee

145Restructuring Amendment 7/31/2015

EXECUTION VERSION

actions and to receive all or any part of its proportionate share of the Net Effective Generating Capacity.

35.5    During any period when the suspension provided for in Section 35.4.1 is in effect, the non-defaulting Party(ies) having a Participation Share in the affected Unit or Units: (i) shall bear a proportionate share of all expenses, including but not limited to, the operation and maintenance costs, insurance costs, fuel costs, capital expenditures and other expenses otherwise payable by the defaulting Party under the Project Agreements, including any obligations related to common equipment and facilities, based upon the relation of the Participation Share of each such non-defaulting Party(ies) to the Participation Shares of all non-defaulting Parties in the specific Unit or Units; and (ii) shall be entitled to schedule and receive for their accounts their proportionate share of the Net Effective Generating Capacity of the defaulting Party.

35.6    In connection with its cure of the default, the defaulting Party shall pay promptly upon demand to the non-defaulting Party(ies) the total amount of money (and/or the reasonable equivalent in money of non-monetary performance) paid and/or made by such non-defaulting Party(ies) pursuant to Section 35.5 in order to cure any default by the defaulting Party, together with interest thereon at the rate of ten percent (10%) per annum, or the maximum legal rate of interest, whichever is the lesser, from the date of the expenditure of such money (or the making of such other performance) by the non-defaulting Party(ies), to the date of such reimbursement by the defaulting Party, or such greater amount as may be otherwise provided in the Project Agreements. Any payment obligation of the

146Restructuring Amendment 7/31/2015

EXECUTION VERSION

defaulting Party shall be reduced by mitigation measures undertaken by the non-defaulting Parties; provided, however, that the payment obligations of the defaulting Party shall not be reduced by any profits or gains achieved by the non-defaulting Parties as the result of taking a proportionate share of the Net Effective Generating Capacity due to the default of the defaulting Party.

35.7    The suspension of a defaulting Party shall be terminated and its full rights under the Project Agreements restored when the default(s) have been cured and all compensable costs incurred by the non-defaulting Party(ies) hereunder have been paid by the defaulting Party or other arrangements acceptable to the non-defaulting Party(ies) have been made.

35.8    No waiver by a non-defaulting Party of its rights with respect to a default under this Agreement, or with respect to any other matter arising in connection with this Agreement, shall be effective unless the non-defaulting Party(ies) waive in writing their respective rights and any such waiver shall not be deemed to be a waiver with respect to any subsequent default or matter. No delay short of the statutory period of limitations in asserting or enforcing any right hereunder shall be deemed a waiver of such right.

35.9    The rights and remedies provided in this Agreement shall be in addition to the rights and remedies of the Parties as set forth and contained in any other Project Agreement or any rights and remedies the Parties have in law or equity.

147Restructuring Amendment 7/31/2015

EXECUTION VERSION

36.0    LIABILITY: 

36.1    Except for any judgment debt for damage resulting from Willful Action and except to the extent any judgment debt is collectible from valid insurance, and subject to the provisions of Sections 36.1.1, 36.4, 36.5, 36.6 and Section 37, each Party hereby extends to all other Parties, 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 Party, its directors, members of its governing body, officers, employees or any person or entity whose negligence would be imputed to such Party from (i) Operating Work, the design and construction of Capital Improvements or the use or ownership of the San Juan Project or (ii) the performance or nonperformance of the obligations of any Party under any of the Project Agreements, other than the obligation to pay any monies becoming due.

36.1.1    In the event any insurer providing insurance refuses to pay any judgment obtained by a Party against any other Party, its directors, members of its governing body, officers or employees on account of liability referred to in Section 36.1, the Party, its directors, members of its governing body, officers or employees against whom the judgment is obtained shall, at the request of the prevailing Party and in consideration for the covenant granted in Section 36.1, execute such documents as may be necessary to effect an assignment of its

148Restructuring Amendment 7/31/2015

EXECUTION VERSION

contractual rights against the nonpaying insurer and thereby give the prevailing Party the opportunity to enforce its judgment directly against such insurer. In no event when a judgment debt is collectible from valid insurance shall the Party obtaining the judgment execute, levy or otherwise enforce the judgment (including recording or effecting a judgment lien) against the Party, its directors, members of its governing body, officers or employees against whom the judgment was obtained.

36.1.2    To the extent that Section 41‑3‑5, New Mexico Statutes Annotated, 1978 compilation (as such section may be amended), shall be applicable and for the purpose of relieving each Party, its directors, members of its governing body, officers and employees of any liability to make contribution to other non‑Party tortfeasors, the foregoing covenant not to execute hereby effects a reduction of all injured Parties’ damages recoverable against all other non‑Party tortfeasors to the extent of the pro rata share (as referred to in Section 41‑3‑5, New Mexico Statutes Annotated, 1978 compilation, as such section may be amended) of the other Parties, their directors, members of their governing bodies, officers and employees.

36.1.3    Each Party agrees, upon request by any other Party, to make, execute and deliver any and all documents or take such other action as may reasonably be required to effectuate the intent of this Section 36.1.

36.2    Except as provided in Sections 36.4, 36.5 and 36.6, the costs and expenses of discharging all work liability imposed upon one or more of the Parties, for which payment is not made by insurance, shall be allocated among the Parties in proportion to

149Restructuring Amendment 7/31/2015

EXECUTION VERSION

their respective Participation Shares in the property giving rise to the work liability. Work liability is defined as liability of one or more Parties for any loss, damage, claim, cost, charge or expense of any kind or nature (including direct, indirect or consequential) suffered or incurred by any party other than a Party, whether or not resulting or to result in the future from the negligence of any Party, its directors, members of its governing body, officers, employees or any other person or entity whose negligence would be imputed to such Party, that has resulted or may result in the future from (i) performance or nonperformance of the work herein described, (ii) operation, maintenance, use or ownership of the San Juan Project, and (iii) past or future performance or nonperformance of the obligations of any Party under any of the Project Agreements.

36.3    If it cannot be determined which property gave rise to work liability, the allocation for discharging costs and expenses associated therewith shall be as specified in Section 22.1.7.

36.4    Except for liability resulting from Willful Action (which subject to the provisions of Section 36.6 shall be the responsibility of the willfully acting Participant), any Party whose electric customer shall have a claim or bring an action against any other Party for any death, injury, loss or damage arising out of or in connection with electric service to such customer caused by the operation or failure of operation of the San Juan Project or any portion thereof shall indemnify and hold harmless such other Party, its directors, members of its governing body, officers and employees from and against any liability for such death, injury, loss or damage.

150Restructuring Amendment 7/31/2015

EXECUTION VERSION

36.5    Each Party shall be responsible for any damage, loss, claim, cost, charge or expense that is not covered by insurance and results from its own Willful Action as defined in Section 5.57.2 and shall indemnify and hold harmless the other Parties, their directors, members of their governing bodies, officers and employees, from any such damage, loss, claim, cost, charge or expense.

36.6    Except as provided in Section 36.5, the aggregate liability of any Party to all other Parties for Willful Action not covered by insurance shall be determined as follows:

36.6.1    All such liability for damages, losses, claims, costs, charges or expenses of such Party shall not exceed ten million dollars ($10,000,000) per occurrence. Each Party extends to each other Party, its directors, members of its governing body, officers and employees its covenant not to execute, levy or otherwise enforce a judgment against any of them for any such aggregate liability in excess of ten million dollars ($10,000,000) per occurrence.

36.6.2    A claim based on Willful Action must be perfected by filing suit in a court of competent jurisdiction within three (3) years after the Willful Action occurs. All claims made thereafter relating to the same Willful Action shall be barred by this Section 36.6.2. The award to each nonwillfully acting Party from each Participant determined to have committed Willful Action shall be determined as follows:  (i) Each Party who successfully files suit for remuneration shall receive the lesser of (a) its final judgment awarded (or settlement made) or (b) its pro rata Participation Share of the ten million dollar ($10,000,000) maximum recovery

151Restructuring Amendment 7/31/2015

EXECUTION VERSION

established in Section 36.6.1; (ii) When all pending suits are resolved, those Parties who were awarded judgments or reached settlements but whose claims were not fully satisfied pursuant to Section 36.6.2(i) shall be entitled to participate in any remaining portion of the ten million dollar ($10,000,000) maximum recovery limit, based upon the ratio of the unsatisfied portion of such Party’s judgment or settlement to the total unsatisfied portion of all such judgments and settlements. Such participation shall be limited to the Parties’ unsatisfied judgments or settlements.

36.7    The provisions of this Section 36 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 insurance policies.

36.8    If a court of competent jurisdiction determines upon a challenge by a Party or third party that the provisions of Section 56-7-1, New Mexico Statutes Annotated, 1978 Compilation, as amended, are applicable to this Agreement, the Parties agree that any agreement to indemnify contained in this Agreement shall be enforced only to the extent it requires the indemnitor to indemnify or hold harmless the indemnitee, including its officers, employees or agents, against liability, claims, damages, losses or expenses, including attorney’s fees, only to the extent that the liability, damages, losses or costs are caused by, or arise out of, the acts or omissions of the indemnitor or its officers, employees or agents.

152Restructuring Amendment 7/31/2015

EXECUTION VERSION

36.9    The Parties agree that the aggregate liability limit of ten million dollars ($10,000,000) referenced in Sections 36.6.1 and 36.6.2 may be determined in the future to be inappropriate and shall, at the request of any Party, make a good faith effort to evaluate and, if appropriate, revise said limit.

37.0    ARBITRATION:

37.1    If a dispute between or among any of the Parties (which term, for purposes of this Section 37, shall be deemed to include the Operating Agent) should arise in relation to the performance or nonperformance of any obligation under this Agreement, any Party(ies) may call for submission of the dispute to arbitration, which call shall be binding upon all of the other affected Party(ies). Disputes arising under the Mine Reclamation Agreement and the Decommissioning Agreement shall be resolved pursuant to the dispute resolution provisions of those agreements. Disputes arising under Sections 4.3 or 5 of the Restructuring Agreement, which provisions are incorporated into Sections 7.13.1 and 23 of this Agreement, shall be resolved pursuant to the dispute resolution provisions of this Agreement. Any other disputes arising under the Restructuring Agreement shall be resolved pursuant to the dispute resolution provisions of the Restructuring Agreement.

37.2    The Party(ies) calling for arbitration shall give written notice to all other Parties, setting forth in such notice in adequate detail the entity(ies) against whom relief is sought, the nature of the dispute, the amount or amounts, if any, involved in such dispute, and the remedy sought by such arbitration proceedings. Within twenty (20) days after receipt of such notice, any other Party(ies) involved may, by written response to the first Party(ies), as well as the other Party(ies), 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 Party(ies) first submitting its or their notice of the matter at issue shall have

37.3    Within ten (10) days following delivery of the last written submittal pursuant to Section 37.2, the affected Party(ies), acting through their respective representatives, shall meet for the purpose of selecting arbitrators. Each affected Party, or group of Parties, 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 arbitrator(s), the number of which additional arbitrators shall be one (1) less than the total number of arbitrators selected by the affected Parties. If the arbitrators selected by the affected Parties, 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 similar organization if the American Arbitration Association should not exist at the time) a list of arbitrators who are qualified and eligible to serve as hereinafter provided. The arbitrators selected by the affected Parties shall take turns striking names from the list of arbitrators furnished by 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 an officer or employee of any of the Parties to the dispute or is otherwise interested in the matter to be arbitrated.

37.4    Except as otherwise provided in this Section 37 or otherwise agreed by the Parties to the dispute, the arbitration shall be governed by the rules and practices of the

155Restructuring Amendment 7/31/2015

EXECUTION VERSION

American Arbitration Association (or rules and practices of a similar organization if the American Arbitration Association should not exist at that time) from time to time in force, except that if such rules and practices, as modified herein, shall conflict with New Mexico Rules of Civil Procedure or any other provisions of New Mexico law then in force which are specifically applicable to arbitration proceedings, such New Mexico laws shall govern.

37.5    Included in the issues which may be submitted to arbitration pursuant to this Section 37 is the issue of whether the right to arbitrate a particular dispute is permitted under the Project Agreements.

37.6    The arbitrators shall hear evidence submitted by the respective Parties or group or groups of Parties and may call for additional information, which additional information shall be furnished by the Party having such information. The decision of a majority of the arbitrators shall be binding upon all the Parties and shall be based on the provisions of the Project Agreements and New Mexico law.

37.7    This agreement to arbitrate shall be specifically enforceable and the award of the arbitrators shall be final and binding upon the Parties to the extent provided by the laws of the State of New Mexico. Any award may be filed with the clerk of any court having jurisdiction over the Parties 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.

All other expenses and costs of the arbitration, including attorney fees, shall be borne by the Party incurring the same.

RETIREMENT AND RECONSTRUCTION

38.0    DESTRUCTION, DAMAGE OR CONDEMNATION OF A UNIT:

38.1    If all, or substantially all, of a Unit is destroyed, damaged or condemned, then the Participants with Participation Shares in that Unit by unanimous agreement may elect to repair or reconstruct the damaged, destroyed or condemned Unit in such a manner as to restore the Unit to substantially the same general character or use as the original, or to such other character or use as the Participants may then mutually agree. In the event of such election, it shall be the obligation of the Participants to pay for the costs of such repair or reconstruction in accordance with the Participation Shares of the respective Participants in such Unit, and, upon completion thereof, the Participants’ rights, titles and interests therein shall be as provided in this Agreement. The retirement of Units 2 and 3 shall not be within the scope of this Section 38.

38.2    Failure to reach unanimous agreement as provided in Section 38.1 shall be deemed to be an election not to repair or reconstruct the damaged, destroyed or condemned Unit, in which event the proceeds from any insurance or from any award shall be distributed to the Participants in accordance with their respective Participation Shares in such Unit. The facilities not destroyed, damaged or condemned shall be disposed of by the Participants in a manner to be mutually agreed upon, and the proceeds from such disposition shall be distributed in accordance with the Participation Shares of the respective Participants in such Unit. Nothing in this section shall be deemed to preclude any Participant or group of

Participants in the Unit from agreeing to repair, reconstruct or replace the damaged, destroyed or condemned Unit.

38.3     In the event that less than substantially all of a Unit is destroyed, damaged or condemned, then it shall be the obligation of the Participants having a Participation Share in such Unit to repair or reconstruct such Unit. Each Participant shall be obligated to pay its proportionate share of the costs of such repair or reconstruction in accordance with Section 6.2.

EXECUTION VERSION

40.0    DECOMMISSIONING OF THE PROJECT:    

40.1    The Participants acknowledge the appropriateness of incorporating in a future amendment to this Agreement, or in another appropriate contractual instrument, provisions which address the decommissioning of the San Juan Project and/or of one or more Units. It is recognized, however, that the resolution of issues associated with San Juan Project decommissioning will require protracted study. The Participants therefore agree to establish a task force or other forum for the careful and deliberate consideration of decommissioning issues so that these issues may be addressed and resolved in a timely manner.

Exhibit VI-Attachment A

A&G RATIO APPLICABLE TO OPERATION AND MAINTENANCE FOR THE SAN JUAN GENERATING STATION (“SJGS”)

The Operating Agent determines, in accordance with Accounting Practice, the appropriate A&G expense incurred for the benefit of the SJGS and to be billed to the SJGS as follows:

1.    A&G expenses directly chargeable by on-site San Juan Project employees as set forth in Section 22.2.2;

2.    A&G expenses directly chargeable by A&G related departments located off-site as set forth in Section 22.2.2; and

3.    Indirect A&G expenses included in the development of the A&G ratio.

Except as set forth in Section 22.0, individuals located off-site must either charge their time and expenses direct to the SJGS or be included in the A&G pool in the development of the A&G Ratio. Costs incurred for the same purpose must be either all charged direct to the SJGS or all be included in the A&G pool, e.g., all staff persons within the same department must either charge direct to the SJGS or to the A&G pool.

A. The Operating Agent conducts an A&G study every three years. However, periodic reviews will be performed to determine if significant organizational changes have occurred that may require the Operating Agent to conduct an A&G study on a basis more frequently than three years. This study determines the appropriate amount of indirect A&G expense to utilize in the development of the A&G Ratio described below.

The FERC A&G accounts included in the A&G study are: 920, 921, 923, 930.2, 931 and 935.

Background

The responsibility for the SJGS resides in the Operating Agent’s Bulk Power Business Unit. The A&G expenses charged to this Business Unit are derived from two areas. The first component is an allocation of A&G expenses from the Operating Agent’s Corporate Office to the Bulk Power Business Unit. These allocations are based on pre-determined methodologies. The second component of costs are A&G expenses that are directly charged to the Bulk Power Business Unit. Note: Any A&G expenses charged directly to the SJGS are excluded from the determination of the A&G Ratio and are not subject to the A&G Ratio.

Exh. VI-1

A questionnaire is sent to all managers that have A&G charges to the Bulk Power Business Unit to determine what percentage of their A&G expenses should be included in the development of the A&G Ratio.

The percentages derived from the questionnaires are then applied to the actual A&G amounts charged to the Bulk Power Business Unit for the study year. Amounts are split between labor and other.

B. Labor Ratios for Payroll Taxes (FERC Account 408), Injuries and Damages (FERC Account 925) and Pension and Benefits (FERC Account 926) (See Exhibit VI Attachments B, C and D) are applied to the labor portion of the A&G determined above.

C. Other costs included in the development of the A&G Ratio are Depreciation of General Plant (FERC Account 403), Property Insurance (FERC Account 924) and Property Taxes (FERC Account 408) for the Operating Agent’s headquarters buildings and energy management facility and Amortization of Computer Software (FERC Account 404) for certain software applications that provide benefit to the SJGS.

The portion of the costs related to the Operating Agent’s headquarters buildings included in the development of the A&G Ratio are derived by applying certain ratios obtained from the A&G study questionnaires. The costs included in the A&G Ratio for the Operating Agent’s energy management facility are based on the number of MW of SJGS capacity as a percentage of the Operating Agent’s total generating capacity. In addition, ratios for determining the amount of software costs to include in the A&G Ratio are based on the specific software application. For example, if the Operating Agent installed a new payroll system, the amount of costs for this system that would be included in the A&G Ratio calculation would be based on the number of employees at the SJGS as a percent of the Operating Agent’s total employees. The Operating Agent reviews each specific software application to determine the method for assigning the appropriate amount of costs to be included in the A&G Ratio calculation.

The A&G ratio shall be applied to the following SJGS costs:

1) Labor charged to the operation and maintenance expenses included in Sections 22.2.1, 22.3, 22.4, 22.5 and 23.3.3 of the San Juan Project Participation Agreement. Such labor dollars are utilized as the denominator in the calculation of the A&G Ratio described below.

The A&G Ratio shall be derived annually based on the preceding year’s experience, as set forth herein unless otherwise agreed to by the participants. The A&G Ratio will be adjusted to actuals at year-end and the adjustment will be used in the computation of the A&G Ratio for the following year.

A&G Ratio = A/B

Exh. VI - 2

Where A = Administrative and general expense chargeable to FERC Accounts 920, 921,

923, 930.2, 931 and 935, including Labor Ratios for Payroll Taxes (FERC Account 408), Injuries and Damages (FERC Account 925) and Pension and Benefits (FERC Account 926) plus other related costs for the Operating Agent’s headquarters buildings and energy management facility for Property Taxes FERC Account (408), Depreciation of General Plant FERC Account (403), and Property Insurance FERC Account (924) plus amortization of certain Computer Software costs charged to FERC Account (404).

B = Total SJGS operation and maintenance labor paid and accrued excluding labor expenses chargeable to FERC accounts 920 through 935 inclusive.

Proportional Adjustment of Voting Requirements

in Case of a Default and Suspension of the Rights of a Party or Participant

to Vote Pursuant to Section 35.4.1.

Example Calculation Based on Hypothetical Ownership Percentages:

In the following table, Participant D with Participation Shares in Units 3 and 4 is assumed to be the defaulting Participant. Participation Shares for Voting and Number of Participants for Voting are shown under original or pre-default conditions and are then adjusted as provided in Sections 18.4, 19.4, 20.5, and 21.4 after the right of Participant D to vote is suspended pursuant to Section 35.4.1.

Participation Shares for voting pursuant to Sections 18.4.1(a), 18.4.2(a), and 18.4.3(a) are adjusted as follows:

For Units:

The Adjusted Participation Share for a Participant = (That Participant’s Participation Share)/(The sum of the Participation Shares of all non-defaulting Participants in the affected Unit)

For Common Facilities:

Adjustments related to common facilities shall be proportional to any differing Participation Shares between Units. The above formula would be applied to each Unit and then summed and normalized over the applicable common facilities. Because San Juan Units are of unequal ratings, the normalization will be in proportion to each Unit’s rating rather than the even fractions in the example below where equally sized units were used for simplicity.

The numbers of Participants used for voting purposes pursuant to the requirements of Sections 18.4.1(b), 18.4.2(b), and 18.4.3(b) are adjusted by subtracting the number of defaulting Participants from the total number of Participants voting under those Sections.

³Computed on Unit 3 and Unit 4 Common Participation Shares as follows: Unit 3 Contribution = (Participant A) / (Participant A + Participant B + Participant C) =

20%/(20%+20%+30%) = 28.571%; Unit 4 Contribution = (Participant A) / (Participant A + Participant B + Participant C + Participant E) = 10%/(10%+10%+20%+40%) = 12.500%.

Unit 3 & 4 Common = (Unit 3 Rating)/(Sum of Unit 3 and Unit 4 Ratings) * (Unit 3 Contribution) + (Unit 4 Rating)/(Sum of Unit 3 and Unit 4 Ratings) * (Unit 4 Contribution) = 1/2 (28.271%) + 1/2 (12.500%) = 20.536%

⁴Computed on Plant Common Participation Shares as follows: Unit 1 Contribution = (Participant A) / (Participant A + Participant B) = 50%/(50%+50%) = 50.000%; Unit 2 Contribution = (Participant A) / (Participant A + Participant B) = 50%/(50%+50%) = 50.000%. Unit 3 Contribution = (Participant A) / (Participant A + Participant B + Participant C) = 20%/(20%+20%+30%) = 28.571%; Unit 4 Contribution = (Participant A) / (Participant A + Participant B + Participant C + Participant E) =

10%/(10%+10%+20%+40%) = 12.500%. Plant Common = (Unit 1 Rating)/(Plant

Rating) * (Unit 1 Contribution) + (Unit 2 Rating)/(Plant Rating) * (Unit 2 Contribution) + (Unit 3 Rating)/(Plant Rating) * (Unit 3 Contribution) + (Unit 4 Rating)/(Plant Rating) * (Unit 4 Contribution) = 1/4 (50.000%) + 1/4 (50.000%) + 1/4 (28.571%) + (1/4 (12.5000%) = 35.268%
