9.5.Any action or determination of the Coordination Committee shall require the following vote:
(a)With respect to actions or determinations that do not pertain to the Switchyard Facilities or Decommissioning:
(i)    The affirmative vote of the Participants owning at least 75% of the Net Effective Generating Capacity; and 
33






(ii)    the affirmative vote of at least 60% of the individual Participants.  For purposes of this Section 9.5(a)(ii) (or Sections 9.5(b)(i)(B) or 9.5(b)(ii)(B)) and any other provisions requiring the vote of a committee, for any two or more Participants where: (i) one of the Participants directly or indirectly controls the other Participant(s) or (ii) the Participants are under common control (e.g., subsidiaries or affiliates), such two or more Participants shall be deemed one individual Participant and represent one individual vote.
(b)With respect to actions or determinations that pertain to the Switchyard Facilities or Decommissioning:
(i)    For a matter pertaining to the Switchyard Facilities, the right to vote on a particular action or determination shall be based on a Participant’s ownership interest in that portion of the Switchyard Facilities that is the subject of the particular action or determination, and shall require (A) the affirmative vote of the Participants owning at least 75% of the ownership interest in such portion of the Switchyard Facilities and (B) the affirmative vote of at least 60% of such individual Participants; and  
(ii)    For a matter pertaining to Decommissioning, the right to vote on a particular action or determination shall be based on a Participant’s Decommissioning obligation as a Decommissioning Participant in that portion of the Decommissiong obligation that is the subject of the particular

9.7.For purposes of Section 9, a “Capital Improvement” shall have the meaning set forth in Section 5.5(a), but also mean a singular project for which the total aggregate cost, which may include multiple purchase orders and multiple contractors, exceeds $200,000,000.00.  In the event a Capital Project involves Unit 4 or Unit 5, each unit shall be treated separately and the $200,000,000 amount shall apply per unit and not be aggregated.
35






9.8.In no event may the Operating Agent, as that term is defined in the Operating Agreement, claim that a Capital Improvement meeting the definitions set forth in Section 5.5(a) and Section 9.7, is necessary to operate the Four Corners Project in accordance with Prudent Utility Practice, as provided for in Section 14.4 of the Operating Agreement.
9.9.Beginning on July 6, 2016, Section 9.6(b) shall not apply to the installation of selective catalytic reduction equipment on either Unit 4 or Unit 5, as required by federal law (“SCR Projects”) and SCR Projects shall be subject to the voting requirements of Section 9.5.  
9.10.In the event that the Coordination Committee does not approve a Capital Project subject to the voting requirements of Section 9.6(b), the Participant(s) that voted against the Capital Project shall work in good faith with the Participants that voted in favor of the Capital Project, in order to assure the continued operation of the Four Corners Project, including commercially reasonable efforts by the Participants that voted against the Capital Improvements Project to sell their interests in the Four Corners Project.  If the Participants cannot agree on a sale or transfer of their respective rights, titles and interests to the Four Corners Project, pursuant to Section 13, the Participants agree that each of them shall have the right to seek equitable relief, without being subject to the dispute resolution requirements of Section 19.
9.11.In the event one or more Participants abstains from a vote governed by Section 9.5, does not participate in consideration of a particular matter, notwithstanding the opportunity to do so, or is not entitled to vote pursuant to Section 20.2 of 
36






this Co-Tenancy Agreement, actions or determinations brought before the Coordination Committee shall require the affirmative vote of: 
(a)the Participants owning at least 75% of the remaining Net Effective Generating Capacity (after subtracting the percentage of Net Effective Generating Capacity owned by the abstaining, non-participating, or defaulting Participant(s) and except as provided in (c) below); 
(b)at least 60% of the individual Participants that are voting; and
(c)with respect to actions or determination that pertain to the Switchyard Facilities or Decommissioning.
(i)    For a matter pertaining to the Switchyard Facilities, the right to vote on a particular action or determination shall be based on a Participant’s ownership interest in that portion of the Switchyard Facilities that is the subject of the particular action or determination, and shall require (A) the affirmative vote of the Participants owning at least 75%. of the remaining ownership interest in such portion of the Switchyard Facilities and (B) the affirmative vote of at least 60% of such individual Participants that are voting.  
(ii)    For a matter pertaining to Decommissioning, the right to vote on a particular action or determination shall be based on a Participant’s Decommissioning obligation as a Decommissioning Participant in that portion of the Decommissiong obligation that is the subject of the particular action or determination, and shall require (A) the affirmative vote of the Participants having at least 75% of the remaining 
37






Decommissioning obligation and (B) the affirmative vote of at least 60% of such individual Participants that are voting. 
9.12.In the event one or more Participants abstains from or does not participate in a vote governed by Section 9.6, or cannot vote as a result of a default, actions or determinations brought before the Coordination Committee shall require the unanimous affirmative vote of the voting Participants.
9.13.A Participant shall abstain from voting on any matter if the Participant has a conflict of interest with respect to that matter.  
9.14.Each Participant shall advise the Coordination Committee if the Participant has a conflict of interest with respect to any matter being considered by the Coordination Committee, provided that the failure of a Participant to advise the Coordination Committee of a conflict of interest shall not relieve that Participant of its obligation to abstain from voting on the matter.  A conflict of interest shall include matters relating to the new uses of land or other property rights for the Four Corners Project and contracts or other agreements to provide goods or services (other than the services provided by the Operating Agent), including fuel, to the Four Corners Project, where such Participant or such Participant’s parent or an affiliate of such Participant is the counterparty to such contract or agreement.  The determination of whether a conflict of interest exists shall be made by the Coordination Committee.
9.15.For the avoidance of doubt, in the event of matters involving directly or indirectly the permanent shutdown of the operations of the Four Corners Project and/or the termination of the 2016 Four Corners Coal Supply Agreement, as amended and including the 2025 Four Corners Coal Supply 
38






Agreement (the “CSA”), NTEC affirmatively agrees and acknowledges that it will or may have a conflict of interest in such matter(s), and expressly agrees that neither NTEC, nor any successor in interest or assignee (whether pursuant to Section 12 or otherwise): (i) shall oppose or object to such matter(s) or (ii) shall have any vote as to such matter(s). This provision overrides and supersedes anything contrary to, or directly or indirectly inconsistent with, this provision in the Project Agreements, the CSA, or any other related documents.
10.USE OF COMMON FACILITIES AND RELATED FACILITIES DURING CURTAILMENTS:

10.1.If, because of emergency or planned shutdowns of Common Facilities or Related Facilities or the curtailment for any cause in the use thereof, Units 1, 2, 3 (prior to their respective retirements), 4 and 5 are not all operable simultaneously and continuously at their Net Effective Generating Capacity, then the reduced capacity entitlement of each Participant, because of the inability to operate said Units simultaneously and continuously at their Net Effective Generating Capacity, shall be determined as follows:
Reduced Capacity Entitlement of 
Initial Four Corners Plant 


C  =      N x NEGC1 
NEGC2 


Reduced Capacity Entitlement of 
Four Corners Project


CD1U = N x (NEGC2 – NEGC1) x P
NEGC2


Where:

C = Reduced capacity entitlement of Arizona in Initial Four Corners Plant. 
39








CD1U = With respect to each Participant, the reduced capacity entitlement of such Participant in the Four Corners Project. 


N = Reduced Net Effective Generating Capacity of the Enlarged Four Corners Generating Station. 


NEGC1 = The Net Effective Generating Capacity of the Initial Four Corners Plant at the time of such emergency or planned shutdown or curtailment. 


NEGC2 = The Net Effective Generating Capacity of the Enlarged Four Corners Generating Station at the time of such emergency or planned shutdown or curtailment. 


P = With respect to each Participant, such Participant’s percentage of Net Effective Generation under Section 8.1.


10.2.Curtailments in capacity entitlements necessitated by reason of shortages in the supply of fuel, water or other supplies or services affecting all of the five Units of the Enlarged Four Corners Generating Station commonly shall be treated in the same manner as curtailments necessitated because of emergency or planned shutdowns of Common Facilities or Related Facilities; provided, however, that nothing contained in this Section 10 shall be construed to diminish the respective rights of the Participants in the Minimum Coal Storage Pile.
10.3.Except as otherwise provided in Section 10, no Participant shall exercise its rights relating to the Common Facilities or Related Facilities so as to endanger or unreasonably interfere with the operation of the Initial Four Corners Plant (prior to the retirement of each of Units 1, 2 and 3 of the Initial Four Corners Plant) or the Four Corners Project.
11.WAIVER OF RIGHT TO PARTITION:
40






11.1.The Participants, and each of them, accept title to the Four Corners Project and title in the Granted Lands and Leased Lands as tenants in common, and agree that their interests therein shall be held in such tenancy in common for the duration of the term of this Co-Tenancy Agreement, including any extension thereof. Notwithstanding the above, as elsewhere provided herein New Mexico is a tenant in common only for Retained Interest and Decommissioning obligations of New Mexico. During the term of this Co-Tenancy Agreement, each Participant agrees as follows:
11.1.1.That it hereby waives the right to partition the Four Corners Project or the Granted Lands and Leased Lands (whether by partitionment in kind or by sale and division of the proceeds thereof); and
11.1.2.That it will not resort to any action at law or in equity to partition (in either such manner) the Four Corners Project or the Granted Lands and Leased Lands, and waives the benefits of all laws that may now or hereafter authorize such partition.
11.2.During the term of this Co-Tenancy Agreement, Arizona waives the right to partition (whether by partitionment in kind or by sale and division of the proceeds thereof) and agrees that it will not resort to any action at law or in equity to partition (in either such manner) and waives the benefits of all laws that may now or hereafter authorize such partition of the Common Facilities and the Related Facilities allocated to the Initial Four Corners Plant from the Common Facilities and the Related Facilities allocated to the Four Corners Project.
41






11.3.During the term of this Co-Tenancy Agreement, the Participants waive the right to partition (whether by partitionment in kind or by sale and division of the proceeds thereof) and agree that they will not resort to any action at law or in equity to partition (in either such manner) and waive the benefits of all laws that may now or hereafter authorize such partition of the Common Facilities and the Related Facilities allocated to the Four Corners Project from the Common Facilities and the Related Facilities allocated to the Initial Four Corners Plant.
12.MORTGAGE AND TRANSFER OF PARTICIPANTS’ INTERESTS:
12.1.The Participants, and each of them, shall have the right at any time and from time to time to mortgage, create or provide for a security interest in or convey in trust their respective rights, titles and interests in the Four Corners Project, their respective rights, titles and interests in, to and under the Project Agreements and/or their rights, titles and interests in the Granted Lands and Leased Lands, to a trustee or trustees under deeds of trust, mortgages or indentures, or to secured parties under a security agreement, as security for their present or future bonds or other obligations or securities, and to any successors or assigns thereof, without need for the prior written consent of any other Participants, and without such mortgagee, trustee or secured party assuming or becoming in any respect obligated to perform any of the obligations of the Participants.

12.3.Each Participant shall have the right to transfer or assign all or any portion of its respective rights, undivided titles and interests in the Four Corners Project, in, to and under the Project Agreements and/or in the Granted Lands and Leased Lands, without the need for prior written consent of any other Participant, at any time to any of the following:
12.3.1.To any corporation or other entity acquiring all or substantially all of the property of such Participant; or
12.3.2.To any corporation or entity into which or with which such Participant may be merged or consolidated; or
12.3.3.To any corporation or entity the stock or ownership of which is wholly owned by a Participant; or
12.3.4.To any third party transferee in connection with a financing by such Participant involving or relating to such Participant’s rights, titles and interests in the Four Corners Project, in, to and under the Project Agreements and/or in the Granted Lands and Leased Lands, without such third party transferee assuming or becoming obligated in any 
43






respect to perform any of the obligations of such Participant pursuant to this Co-Tenancy Agreement, provided that any and all such rights, titles and interests transferred to such third party transferee are immediately re-purchased by such Participant and are thereupon subject to all of the provisions of this Co-Tenancy Agreement, including, but not limited to, the “right of first refusal” provisions of Section 13 hereof; or

12.4.Except as otherwise provided in Sections 12.1, 12.2, 12.3.4 and 24.4 hereof, any successor to the rights, titles and interests of a Participant in the Four Corners Project, to the rights, titles and interests of a Participant in, to and under the Project Agreements and/or in the Granted Lands and Leased Lands shall assume and agree to fully perform and discharge all of the obligations hereunder of such Participant, and such successor shall notify each of the other Participants in writing of such transfer, assignment or merger. Any such successor shall specifically agree in writing with the remaining Participants at 
44






the time of such transfer, assignment or merger that it will not transfer or assign any rights, titles and interests acquired from a Participant without complying with the terms and conditions of Section 13 hereof.
12.5.No Participant shall be relieved of any of its obligations and duties under the Project Agreements by an assignment under this Section 12 without the express prior written consent of all of the remaining Participants.

12.7.Without implying that any provision other than Article 6 and Article 7 herein allows a Participant to own an undivided ownership interest in any component of the Four Corners Project which is not the same as the undivided ownership interest such Participant owns in every other component, each Participant shall own the same undivided percentage interest in Unit 4 as in Unit 5.
13.RIGHT OF FIRST REFUSAL:
13.1.Except as provided in Section 12 hereof should any Participant desire to assign, transfer, convey or otherwise dispose of (hereinafter collectively referred to as “Assign”) its rights, titles and interests in the Four Corners Project, or its rights, titles and interests, in, to and under the Project Agreements, or its rights, titles and interests in the Granted Lands or Leased Lands, or any part thereof or interest therein (hereinafter referred to as “Transfer Interest”), to any person, company, corporation, governmental agency or sovereign entity, or any other Participant (hereinafter referred to as “Outside Party”), the remaining Participants with ownership in Net Effective Generating Capacity, or any one 
45






or more of them, shall have the right of first refusal, as hereinafter described, to purchase such Transfer Interest on the basis of the greater of the following amounts:
13.1.1.The amount of a bona fide written offer from a buyer ready, willing and able to purchase the Transfer Interest after the expiration of the periods for giving notices specified in Sections 13.3 to 13.7 inclusive hereof; or
13.1.2.The fair market value of the Transfer Interest.  As used herein, the term “fair market value” is defined as 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.  Such value need not be computed upon the basis of a cash sale, but may be computed on the basis of the terms offered in Section 13.1.1.
13.2.Such right of first refusal shall exist as of the effective date of this Co-Tenancy Agreement and shall continue for the term of this Co-Tenancy Agreement.
13.3.At least one hundred eighty (180) days prior to its intended date to Assign, and after its receipt of a bona fide written offer of the type described in Section 13.1 above, the Participant desiring to Assign its Transfer Interest shall serve written notice of its intention to do so upon the remaining Participants who have an interest in that portion of the Four Corners Project that is the subject of the Transfer Interest in accordance with Section 23 of this Co-Tenancy Agreement.  Such notice to the remaining Participants shall contain the 
46






approximate proposed date to Assign, the terms and conditions of said bona fide written offer received by such Participant, and the terms and conditions of the proposed assignment.  The terms and conditions contained in such notice shall be at least as favorable to the remaining Participants as the terms and conditions of said bona fide written offer, or may be the same terms and conditions as set forth in said offer.
13.4.Each remaining Participant having an ownership interest in the portion of Four Corners Project that is the subject of the Transfer Interest, including the Outside Party if such Outside Party is a Participant, shall signify its desire to purchase the entire Transfer Interest, or any percentage interest therein, or not to purchase all or any percentage interest therein, by serving written notice of its intention upon the Participant desiring to Assign and upon the remaining Participants pursuant to Section 23 hereof within one hundred twenty (120) days after such service pursuant to Section 13.3 of the written notice of intention to Assign. Failure by a Participant to serve notice as provided hereunder within the time period specified shall be conclusively deemed to be notice of its intention not to purchase any portion of the Transfer Interest.
13.5.If all or some of the remaining Participants should signify their intention under Section 13.4 to purchase in aggregate more than the entire Transfer Interest, the percentage ownership of the Transfer Interest to be acquired by each such remaining Participant shall be limited to the percentage determined by the formula set forth in Section 13.10.1 hereof.
13.6.If the remaining Participants, or any one or more of them, should signify its or their intention under Section 13.4 to purchase less than the entire Transfer 
47






Interest, the Participant desiring to Assign shall serve written notice of this fact upon the remaining Participants in accordance with Section 23 hereof within ten (10) days after its receipt of the last of the written notices given pursuant to Section 13.4 hereof, or after the expiration of the one hundred twenty (120) day period referred to in Section 13.4 hereof, whichever is earlier.
13.7.The one or more remaining Participants who signify an intention to purchase less than the entire Transfer Interest may signify the intention to purchase the remainder of the Transfer Interest by serving written notice pursuant to Section 23 hereof of its or their intention to do so upon the Participant desiring to Assign within thirty (30) days after the receipt of written notice given pursuant to Section 13.6 hereof.
13.8.When intention to purchase the entire Transfer Interest has been indicated by notices duly given hereunder by the applicable Participant(s) desiring to purchase the Transfer Interest, the Participants shall thereby incur the following obligations:
13.8.1.The Participant desiring to Assign and the Participant(s) desiring to purchase the Transfer Interest shall be obligated to proceed in good faith and with diligence to obtain all required authorizations and approvals to Assign;
13.8.2.The Participant desiring to Assign shall be obligated to obtain the release of any liens imposed by or through it upon any part of the Transfer Interest, and to Assign the Transfer Interest at the earliest practicable date thereafter; and
48






13.8.3.The Participant(s) desiring to purchase the Transfer Interest shall be obligated to perform all terms and conditions required of it or them to complete the purchase of the Transfer Interest.  The purchase of the Transfer Interest shall be fully consummated within eighteen (18) months following the date upon which all notices required to be given under this Section 13 have been duly served, unless the Participant(s) are then diligently pursuing applications to appropriate regulatory bodies (if any) for required authorizations to effect such assignment or are then diligently prosecuting or defending appeals from orders entered or authorizations issued in connection with such application, in which case the purchase of the Transfer Interest shall be fully consummated at the earliest possible date following issuance of the requested authorization(s) or the resolution of any appeal.
13.9.If the intention to purchase the entire Transfer Interest has not been indicated by notices given within the time periods specified in this Section 13 by the Participant(s) desiring to purchase the Transfer Interest, the Participant 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 bona fide written offer of the type described in Section 13.1.1 upon the terms and conditions set forth in said bona fide written offer.  If such assignment of the entire Transfer Interest to the Outside Party is not completed within eighteen (18) months after the approximate proposed date to assign specified in the notice given pursuant to Section 13.3, the Participant desiring to Assign its Transfer Interest must, unless it is then diligently pursuing its applications to appropriate regulatory bodies (if any) for 
49






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, give another complete new right of first refusal to the remaining Participants pursuant to the provisions of this Section 13, before such Participant shall be free to Assign a Transfer Interest to said Outside Party.
13.10.The Participant(s) who purchase the Transfer Interest shall receive title to and shall own the Transfer Interest as tenants in common, subject to the same rights and obligations as are applied to the Transfer Interest in the hands of the assigning Participant, and shall acquire the Transfer Interest as follows:
13.10.1.Unless otherwise agreed to by the purchasing Participants, if there is more than one purchasing Participant, the percentage interest of each such purchasing Participant in the Transfer Interest shall be determined by the following formula: 
T =     A x C 
B 

Where: 
T =     The percentage of the Transfer Interest to be purchased by each Participant desiring to purchase. 
A =     The existing undivided percentage interest of such Participant in the capacity entitlement of the Four Corners Project. 
B =     The total undivided percentage interests in the capacity entitlement of the Four Corners Project of all Participants desiring to purchase the Transfer Interest. 
C =     The percentage interest in the Four Corners Project of the Transfer Interest.
50






13.10.2.If there is only one purchasing Participant, it shall acquire title to and own the entire Transfer Interest.
13.11.No assignment of a Transfer Interest, whether to another Participant or to an Outside Party, shall relieve the assigning Participant from full liability and financial responsibility for performance after any such assignment:
13.11.1.Of all obligations and duties incurred by such Participant prior to such assignment under the terms and conditions of the Project Agreements; and/or
13.11.2.Of all obligations and duties provided and imposed after such assignment upon such assigning Participant under the terms and conditions of the Project Agreements; unless and until the assignee shall agree in writing with the remaining Participants to assume such obligations and duties; provided further, however, that such assignor shall not be relieved of any of its obligations and duties by an assignment under this Section 13, without the express prior written consent of all of the remaining Participants. [4See note below.]
13.12.Any transferee, successor or assignee, or any party who may succeed to the Transfer Interest pursuant to this Section 13, shall specifically agree in writing with the remaining Participants 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 13.

* [Note:  In connection with the transfer by Edison of its interests to Arizona, the following provision was agreed to:  In accordance with Section 13.11.2 of the Co-Tenancy Agreement, Arizona agrees to assume from and after the Amendment No. 7 Effective Date the obligations and duties of Edison under the Project Agreements.  In accordance with Section 13.12 of the Co-Tenancy Agreement, Arizona agrees that it shall not transfer or assign all or any portion of the Transfer Interest acquired by Arizona upon consummation of the Edison Interest Transfer without complying with Section 13 of the Co-Tenancy Agreement.]
51






13.13.Nothing contained in this Section 13 shall be deemed to apply to or limit the right of Arizona to assign, transfer, convey or otherwise dispose of its rights, titles and interests in the Initial Four Corners Plant, or its rights, titles and interests in, to and under the Project Agreements insofar as they relate to the Initial Four Corners Plant, or its rights, titles and interests in the Granted Lands or Leased Lands, or any part thereof or interest therein, insofar as such lands are granted or leased to Arizona under the Amended Original Lease and the Arizona §323 Grant.
13.14.Any assignment of a Transfer Interest to an Outside Party that is not then a Participant that is a governmental or sovereign entity, agency or instrument of a governmental or sovereign entity or a foreign person shall not be effective unless the assumption by such Outside Party of the obligations of the transferring Participant includes a waiver of sovereign immunity, a consent to the dispute resolution provisions of Section 19 of this Co-Tenancy Agreement, a consent to the governing law provisions of Section 25.4 of this Co-Tenancy Agreement, and any other consents or waivers the Participants deem necessary, sufficient to assure the remaining Participants of the enforceability of the obligations of such Outside Party under the Project Agreements.
13.15.A Party shall be prohibited from assigning its Transfer Interest to an Outside Party unless such Outside Party, concurrently with such transfer, provides to the Operating Agent any financial assurance or guarantee required by the Financial Assurance Policy, attached as Exhibit 1 to Amendment No. 16 of the Operating Agreement, as then in effect, and the transferring Participant provides evidence, to the reasonable satisfaction of the non-transferring 
52






Participants, that the transferee, successor or assignee, or any party who may succeed to the Transfer Interest pursuant to this Section 13 is financially capable, or provides reasonable financial assurances, of fulfilling the obligations under the Co-Tenancy Agreement.

15.4.In the event of the removal or retirement of any facilities comprising part of the Four Corners Project, any proceeds realized from the salvage of such facilities shall be distributed to the Participants in accordance with their percentage ownership interests therein, or shall be applied on account of the Participant’s obligations to pay for Capital Additions, Capital Betterments or Capital Replacements replacing facilities removed or retired.
15.5.Each Participant shall have the right, at its own expense, to add facilities to the Leased Lands including the Switchyard Facilities and to use the portion of the Leased Lands occupied by such facilities, subject to approval pursuant to Section 8.6 of the Operating Agreement; provided, however, the facilities shown on Exhibit 7 and Exhibit 8 hereto shall be deemed to have been so approved.  However, if such additions of facilities involve a new interconnection to the Switchyard Facilities, approval to interconnect to the Switchyard Facilities shall be set forth in a written agreement among the Participants.

20.DEFAULTS AND COVENANTS REGARDING OTHER AGREEMENTS:
20.1.Each Participant hereby agrees with all of the other Participants that it shall pay all monies and carry out all other performances, duties and obligations agreed to be paid and/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 Participant in the covenants and obligations to be by it kept and performed pursuant to the 
63






terms and conditions set forth and contained in any of the Project Agreements shall be an act of default under this Co-Tenancy Agreement.
20.2.Upon: (a) a default in the payment by a Participant of any amount due pursuant to the monthly bill from the Operating Agent, (b) a default by a Participant of any other amount due from such Participant (subsentences (a) and (b) hereinafter collectively referred to as a “Payment Default”), or (c) an event of default for any other reason, then:
20.2.1.[Reserved]
20.2.2.The Operating Agent shall, and any non-defaulting Participant may, give written notice of such default to each member of the Coordination Committee.
20.2.3.If the default is a Payment Default, and provided that the defaulting Participant has received fifteen (15) days prior written notice of the Payment Default, pursuant to Section 20.2.2, the Operating Agent or such other entity designated by the Coordination Committee shall draw on or seek payment under the Financial Assurance Policy, with respect to the defaulting Participant, for the amount in default.  If adequate funds are not available under the Financial Assurance Policy, the Operating Agent is authorized to include in the next monthly bills to the non-defaulting Participants the amount required to fund any shortfall resulting from the Payment Default, such amount to be allocated among the non-defaulting Participants as follows:
NP Share = NEGC of NP/(100 – NEGC of DP)
where:
64






“NP Share” is the share of the shortfall to be funded by a non-defaulting Participant;
“NEGC of NP” is the percentage of Net Effective Generating Capacity of that Participant;
“NEGC of DP” is the percentage of Net Effective Generating Capacity of the defaulting Participant;
provided that the aggregate shortfall to be funded by the non-defaulting Participants at any time shall not exceed $250,000,000, as adjusted to reflect changes in the Consumer Price Index after July 6, 2016.
20.2.4.If the Operating Agent or such other entity designated by the Coordination Committee draws on or seeks payment under the Financial Assurance Policy, the Operating Agent shall give written notice of the same to each member of the Coordination Committee.
20.2.5.For a Payment Default that remains uncured, the Operating Agent or such other entity designated by the Coordination Committee, shall, on the sixtieth (60th) day following the original written notice of default, as set forth in Section 20.2.2, suspend the defaulting Participant’s voting rights and its entitlement to its Net Effective Generating Capacity from the Four Corners Project.  The suspension of a defaulting Participant’s rights shall not suspend its obligations under the Project Agreements. 
20.2.6.For a performance default that is not being disputed, the Operating Agent or such other entity designated by the Coordination 
65






Committee, may, on the sixtieth (60th) day following the original written notice of default, as set forth in Section 20.2.2, suspend the defaulting Participant’s voting rights.  The suspension of a defaulting Participant’s voting rights shall not suspend its obligations under the Project Agreements.  A suspension under this Section 20.2.6 shall require the approval of the Coordination Committee.
20.2.7.Upon a suspension for a Payment Default, as set forth in Section 20.2.5, the non-defaulting Participants, through the Coordination Committee, may either reduce the energy generation of the Four Corners Project or one or more non-defaulting Participants may elect to take additional generation from the Four Corners Project.  If more than one non-defaulting Participant elects to take additional generation from the Four Corners Project, the amount of additional generation shall be apportioned in accordance with their respective Net Effective Generating Capacity or as they may otherwise agree.  Any non-defaulting Participant that takes additional generation from the Four Corners Project shall be responsible for the non-capital operating expenses, including fuel costs, associated with such additional generation.  
20.2.8.For a period of 180 days from the notice of a Payment Default, set forth in Section 20.2.2, the defaulting Participant may reinstate its entitlement to its Net Effective Generating Capacity by paying to the respective non-defaulting Participants the total amount of money (and/or the reasonable equivalent in money for services or property 
66






provided) paid by each non-defaulting Participant, together with interest thereon at a rate of interest 2 percent greater than the “prime rate.”  The right of a defaulting Participant to reinstate its entitlement to its Net Effective Generating Capacity, shall be limited to three times during the term of the Project Agreements (provided such right may be exercised only once in any five (5) year period), unless the Coordination Committee consents to an additional number of times that a defaulting Participant may reinstate its entitlement to its Net Effective Generating Capacity.   
20.2.9.If the defaulting Participant has not cured a Payment Default during the 180-day cure period set forth in Section 20.2.8, such event of default shall be deemed incurable and the non-defaulting Participants shall have the right to continue to exercise their rights under Section 20.2.7 and shall have the right to permanently transfer the defaulting Participant’s Net Effective Generating Capacity to one or more of the other Participants or a third party (such party being a “Permanent Transferee” and such transfer being a “Permanent Transfer”), who shall: (a) pay the non-capital operating expenses, including fuel costs, and capital expenditures associated with such Net Effective Generating Capacity following the Permanent Transfer and (b) reimburse the other non-defaulting Participants the pro-rata share of any capital expenditures associated with the additional generation used by the Permanent Transferee (as set forth in Section 20.2.7) and funded by the other non-defaulting Participants prior to the Permanent 
67






Transfer.  Such agreement by a Permanent Transferee shall not relieve the defaulting Participant from any other liabilities under the Project Agreements for the remainder of the term of the Project Agreements.
20.3.[Reserved]
20.4.In the event that any Participant shall dispute an asserted default by it, then such Participant shall pay the disputed payment or perform the disputed obligation, but may do so under protest.  The protest shall be in writing, shall accompany the disputed payment, or precede the performance of the disputed obligation, and shall specify the reasons upon which the protest is based.  Copies of such protest shall be mailed by such Participant to all other Participants.  Payments not made under protest shall be deemed to be correct, except to the extent that periodic or annual audits may reveal over or under payment by Participants or may necessitate adjustments.  In the event it is determined by arbitration, pursuant to the provisions of this Co-Tenancy Agreement or otherwise, that the protesting Participant is entitled to a refund of all or any portion of a disputed payment or payments, or is entitled to the reasonable equivalent in money of non-monetary performance of a disputed obligation theretofore made, then, upon such determination, the non-protesting Participants shall pay such amount to the protesting Participant, together with interest thereon at the rate of six percent (6%) per annum from the date of payment or of the performance of a disputed obligation to the date of reimbursement. Reimbursement of the amount so paid shall be made by the 
68






non-protesting Participants in the ratio of their respective capacity entitlements to the total capacity entitlement of all non-protesting Participants.
20.5.[Reserved]
20.6.No waiver by a Participant of its rights with respect to a default under this Co-Tenancy Agreement, or with respect to any other matter arising in connection with this Co-Tenancy Agreement, shall be effective unless all non-defaulting Participants waive 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.
20.7.The rights and remedies provided in this Co-Tenancy Agreement shall be in addition to the rights and remedies of the Participants as set forth and contained in any other of the Project Agreements.
20.8.Other Remedies Available to Non-Defaulting Participants.  The Coordination Committee may elect to impose any one or more of the alternative remedies set forth below, in lieu of or in addition to the remedy set forth in Section 20.2:
20.8.1.Extend the time for the defaulting Participant to cure the default, before the defaulting Participant’s Net Effective Generating Capacity is temporarily or permanently transferred to the non-defaulting Participants.
20.8.2.Seek injunctive relief against or specific performance by the defaulting Participant to compel performance by the defaulting Participant of its obligations hereunder to permit the non-defaulting Participants to exercise their remedies herewith.

20.9    Pinnacle West Capital Corporation (“PNW”) has guaranteed the payment obligations of NTEC under this Section 20 pursuant to a Guarantee in favor of the Participants dated July 3, 2018 (the “Guarantee”).  In the event that PNW funds one or more of NTEC’s payment obligations under this Section 20 pursuant to the Guarantee, then NTEC shall be deemed to have committed a Payment Default.  The Payment Default shall commence on the date the payment is made by PNW and continue until such time as NTEC provides a written notice to the Operating Agent certifying that NTEC has repaid PNW for all amounts paid by PNW on behalf of NTEC under the Guarantee (the “Cure Notice”).  The Cure Notice must be executed by a duly authorized officer of NTEC, and countersigned as being true and correct by a duly authorized officer of PNW.  The period during which the Payment Default is in effect is referred to as the “Default Period.”  During the Default Period, NTEC shall be subject to all of the default provisions of Section 20.  Notwithstanding the foregoing, in no event shall the non-defaulting Participants be responsible for any shortfall resulting from NTEC’s default as a Participant, as otherwise set forth in Section 20.2.3 of the Co-Tenancy Agreement. The provisions of this Section 20.9 shall be terminated and of no force or effect at such time as the Participants irrevocably release PNW of its obligations under the Guarantee and any amounts paid by PNW thereunder have been fully reimbursed by NTEC.

76






25.1.Each Participant agrees, upon request by the other Participant, to make, execute and deliver any and all documents reasonably required to implement the terms of this Co-Tenancy Agreement.
25.2.No Participant shall be considered to be in default in the performance of any of the obligations hereunder (other than obligations of any of said Participants to pay costs and expenses) if failure of performance shall be due to uncontrollable forces.  The term “uncontrollable forces” shall mean any cause beyond the control of the Participant affected, including but not limited to failure of facilities, flood, earthquake, storm, fire, lightning, epidemic, war, riot, civil disturbance, labor dispute, sabotage and restraint by Court order or public authority, which by exercise of due diligence and foresight such Participant could not reasonably have been expected to avoid and which by exercise of due diligence it shall be unable to overcome.

Any party rendered unable to fulfill any obligation by reason of uncontrollable forces shall exercise due diligence to remove such inability with all reasonable dispatch.
25.3.Any federal or state regulatory or legal prohibition that prevents performance by a Participant of its obligations hereunder shall constitute an “uncontrollable force” provided that such Participant shall have provided to the other Participants an opinion of independent counsel confirming the effect of the regulatory or legal prohibition.  Such federal or state regulatory or legal prohibition shall not excuse the affected Participant from its payment obligations, including operating expenses, capital expenditures, 
77






Decommissioning costs, or liabilities to the other Participants.  If, after reasonably commercial efforts, the affected Participant is unable to mitigate the federal or state regulatory or legal prohibition to allow it to substantially perform its obligations under the Project Agreements, the affected Participant may meet its financial obligations through one or more of the following alternatives:
(a)Transfer or sale of the affected Participant’s Net Effective Generating Capacity to an unregulated affiliate of the affected Participant or to a third party; or 
(b)Allow one or more of the other Participants to utilize the affected Participant’s Net Effective Generating Capacity until such federal or state regulatory or legal prohibition is removed; provided that the Participant(s) utilizing the affected Participant’s Net Effective Generating Capacity agree(s) to pay all associated non-capital operating costs.

83






any other Navajo Nation arm, instrumentality or entity other than  NTEC, whether such property is held in trust by the United States, or otherwise, and  nothing herein shall be construed to create a lien of any kind in the property of NTEC, the Navajo Nation, or any other, arm, entity or instrumentality of the Navajo Nation. 
26.6.9.NTEC clearly, expressly, unequivocally, and irrevocably waives its sovereign immunity for a Participant’s disputes with NTEC, a Participant’s claims against NTEC, or a Participant’s causes of action against NTEC, but only for a Participant to enforce its rights and the obligations of NTEC created and existing pursuant to the Project Agreements. NTEC clearly, expressly, unequivocally, and irrevocably waives its sovereign immunity for the Participants to seek to obtain, and where deemed appropriate by an arbitrator, an arbitration panel, or a judge of a New Mexico state court of competent jurisdiction, for a Participant to obtain one or more of the following:  (A) to interpret a Project Agreement; (B) to make NTEC perform a specific action NTEC is obligated to perform pursuant to a Project Agreement or to make NTEC discontinue some specific action that NTEC is precluded from performing pursuant to the Project Agreements; or (C) to require NTEC to comply with the duties and obligations clearly and expressly agreed to by NTEC within the Project Agreements.
