The time and date of Closing is hereinafter called the “Closing Date.” Notwithstanding anything in this Agreement to the contrary, the Closing shall be deemed to be effective on the Effective Date, or at such other time as the Parties may mutually agree.

3.2    Purchase Price. The purchase price for the EPE Interest shall be the Net Book Value of the EPE Interest as of the Closing Date (the “Purchase Price”). The Parties agree that the Purchase Price shall be deemed to be $68,907,000, subject to adjustment as set forth in Section 3.3 and Section 3.6. For the avoidance of doubt, the Purchase Price shall not include any costs paid or payable by Purchaser to Seller as part of the Calendar Year 2016 True-Up Payment, the Calendar Year 2017 True-Up Payment, and/or the Calendar Year 2018 True-Up Payment. The obligation of Buyer to pay the Purchase Price to Seller shall be evidenced by the Credit Agreement and the Note, and secured by the Collateral Assignment.

3.3    Post-Closing Adjustments. Within sixty (60) days after the Effective Date, Seller shall prepare and deliver to Purchaser a statement (the “Post-Closing Statement”) that shall set forth the Purchase Price and all adjustments to the Purchase Price proposed by Seller to be required by the definition of Purchase Price in Section 3.2 (the “Proposed Post-Closing Adjustment”); provided that if any adjustments to be made cannot be made within sixty (60) days after the Effective Date, the Parties agree that additional Post-Closing Statements can be subsequently prepared to address such adjustments for a period of up to June 1 of the calendar year following the Effective Date. To the extent applicable, the Post-Closing Statement shall be prepared using the same accounting principles, policies and methods as the Operating Agent has historically used in connection with the calculation of the items reflected on such Post-Closing Statement. Within thirty (30) days after the delivery of the Post-Closing Statement by Seller to Purchaser, Purchaser may object in good faith to the Proposed Post-Closing Adjustment in writing, stating in reasonable detail its objections thereto. Seller and Purchaser agree to cooperate to exchange information used to prepare the Post-Closing Statement and information relating thereto. If Purchaser objects to the Proposed Post-Closing Adjustment, the Parties shall attempt to resolve such dispute by negotiation. If the Parties are unable to resolve such dispute within thirty (30) days after any objection by Purchaser, the Parties shall appoint the Independent Accounting Firm, which shall, at Seller’s and Purchaser’s joint expense, review the Proposed Post-Closing Adjustment and determine the appropriate adjustment to the Purchase Price, if any, within thirty (30) days after such appointment. The Parties agree to cooperate with the Independent Accounting Firm and

provide it with such information as it reasonably requests to enable it to make such determination. For purposes of this Section 3.3 and wherever the Independent Accounting Firm is retained to resolve a dispute between the Parties, the Independent Accounting Firm may determine the issues in dispute following such procedures, consistent with the language of this Agreement, as it deems appropriate to the circumstances and with reference to the amounts in issue. No particular procedures are intended to be imposed upon the Independent Accounting Firm, it being the desire of the Parties that any such disagreement shall be resolved as expeditiously and inexpensively as reasonably practicable. The Independent Accounting Firm shall have no liability to the Parties in connection with such services except for acts of bad faith, willful misconduct or gross negligence, and the Parties shall provide such indemnities to the Independent Accounting Firm as it may reasonably request. The finding of such Independent Accounting Firm shall be binding on the Parties hereto. Upon determination of the appropriate adjustment (the “Post-Closing Adjustment”) by agreement of the Parties or by binding determination of the Independent Accounting Firm, the Party owing the difference shall deliver such amount to the other Party no later than three (3) Business Days after such determination, in immediately available funds or in any other manner as reasonably requested by the payee; provided that upon the written election of Purchaser, if Purchaser is the Party owing money, the amount owed shall instead be added to the face amount of the Note and be subject to the Credit Agreement and Collateral Assignment, and if Purchaser is owed any money, the amount owed shall be credited to reduce the principal amount of the Note.

3.4    Payment. Any cash payments required by this Agreement shall be paid in U.S. dollars in immediately available funds. The recipient of such funds will designate the account or accounts to which the funds will be wire transferred.

3.5    Allocation of Purchase Price. The allocation of the Purchase Price (including any portion of the Assumed Liabilities if applicable) will be negotiated by the Parties in accordance with Applicable Tax Law (as defined below). At least twenty (20) calendar days prior to the Closing Date, Seller shall propose and deliver, or shall have proposed and delivered, to Purchaser a preliminary allocation among the Assets of the Purchase Price and such other consideration to be paid by Seller pursuant to this Agreement (an “Allocation”). The Allocation shall be consistent with Code Section 1060 (“Applicable Tax Law”) and the regulations thereunder and in a manner which facilitates Property Tax reporting and shall separately allocate Assets in the Facilities Switchyard. Purchaser shall within ten (10) days thereafter propose any changes to the Allocation. Within five (5) days following delivery of such proposed changes, Seller shall provide Purchaser with a statement of any objections to such proposed changes, together with a reasonably detailed explanation of the reasons therefor. If Seller and Purchaser are unable to resolve any disputed objections within three (3) days thereafter, such objections shall be referred to the Independent Accounting Firm, which shall resolve the disputed item. The Independent Accounting Firm shall be instructed to deliver to Seller and Purchaser a written determination of the proper allocation of such disputed items within twenty (20) Business Days from the date of engagement. Such determination shall be final, conclusive and binding upon the Parties for all Tax purposes, and the Allocation shall be so adjusted (the allocation, including the adjustment, if any, to be referred to as the “Final Pre-Closing Allocation”). Within thirty (30) days of the determination of the Post-Closing Adjustment, the Parties shall agree to the adjustments to the Final Pre-Closing

Allocation (“Final Allocation”). The fees and disbursements of the Independent Accounting Firm attributable to any Allocation shall be shared equally by Seller and Purchaser. Seller and Purchaser agree to timely file Internal Revenue Service Form 8594, and all Tax Returns, in accordance with such Allocation or Final Allocation, as the case may be, and to report the transactions contemplated by this Agreement for federal Income Tax and all other Tax purposes in a manner consistent with the Allocation or Final Allocation, as the case may be. Each of Seller and Purchaser further agree to provide a copy of its Internal Revenue Service Form 8594 for inspection by the other Party not fewer than ten (10) Business Days prior to filing such form.

(a)    All Transfer Taxes, if any and to the extent required by applicable Laws, incurred in connection with this Agreement and the transactions contemplated hereby shall be borne by Purchaser. Purchaser will file, to the extent required by applicable law, all necessary Tax Returns and other documentation with respect to any such Transfer Taxes, and Seller, if required by applicable law, will join in the execution of any such Tax Returns or other documentation; provided that Seller will be entitled to review in advance any Tax Returns the execution of which it joins pursuant to this Section 6.3(a).

Purchaser shall make such Tax Returns available for Seller’s review and approval (which approval shall not be unreasonably withheld or delayed) no later than fifteen (15) Business Days prior to the due date for filing such Tax Returns, it being understood that Seller’s failure to approve any such Tax Returns shall not limit Purchaser’s obligation to timely file such Tax Returns and duly and timely pay all Taxes shown to be due thereon. Not less than five (5) Business Days prior to the due date of any such Tax Return, Seller shall, to the extent that such Tax has not been prepaid and has not been reflected in an adjustment to the Purchase Price, pay to Purchaser Seller’s prorated portion of the amount shown as due on such Tax Returns as determined in accordance with Section 3.6 of this Agreement and shall, to the extent required by law, join in the execution of any such Tax Returns. Purchaser and Seller shall cooperate in providing each other with any appropriate resale exemption certifications and other similar documentation.

(c)    Purchaser and Seller shall provide the other Party with such assistance as may reasonably be requested by the other Party in connection with the preparation of any Tax Return, any audit or other examination by any taxing authority, or any judicial or administrative proceedings relating to liability for Taxes, and each will retain and provide the requesting Party with any records or information which may be relevant to such return, audit or examination, proceedings or determination. Purchaser and Seller shall retain all books and records with respect to Taxes assessed on the Assets for the full period of any applicable statute of limitations. Any information obtained pursuant to this Section 6.3 or pursuant to any other Section hereof providing for the sharing of information or review of any Tax Return or other schedule relating to Taxes shall be kept confidential by the Parties hereto.

(d)    In the event that a dispute arises between Seller and Purchaser as to the amount of Taxes, the Parties shall attempt in good faith to resolve such dispute, and any amount so agreed upon shall be paid to the appropriate Party.

Notwithstanding anything in this Agreement to the contrary, the fees and expenses of the Independent Accounting Firm in resolving the dispute shall be borne equally by Seller and Purchaser.

6.4    Risk of Loss.

(a)    If, before the Effective Date, all or any portion of the Facilities or the Facilities Switchyard becomes subject to or is threatened with any condemnation or eminent domain proceeding, Seller shall notify Purchaser promptly in writing of such fact. In the event of such taking, Seller, upon the Closing, shall assign to Purchaser any claim, settlement or proceeds thereof.

(b)    If, before the Effective Date all or any portion of the Facilities or the Facilities Switchyard are damaged or destroyed (whether by fire, theft, vandalism or other casualty) in whole or in part, Seller shall, upon the Closing, transfer the proceeds or the rights to the proceeds of applicable insurance to Purchaser.

6.5    Cooperation Relating to Insurance. Until the Closing, Seller will not take any action that will decrease the level of insurance coverage for the Facilities and the Facilities Switchyard as in effect on the date hereof, including, without limitation, property damage and liability insurance, unless agreed by the other Facilities Owners. In addition, Seller agrees to use Commercially Reasonable Efforts to assist Purchaser in making any claims against pre-Closing insurance policies of Seller that may provide coverage related to Assumed Liabilities. Purchaser agrees that it will indemnify Seller for its reasonable out-of-pocket expenses incurred in providing such assistance and cooperation. On and after the Closing, Seller shall authorize the Operating Agent to take any actions necessary to remove Seller from any Facilities Insurance Policies and, except with respect to insurance rights retained by Seller pursuant to Section 2.2(h), Seller agrees to waive its rights with respect to such insurance coverage from and after the Closing. If requested by Seller, Purchaser agrees to exercise Commercially Reasonable Efforts to assist Seller, at Seller’s cost, in obtaining so-called “tail” coverage in respect of claims brought after the Closing for events occurring prior to the Closing, including, if appropriate, listing Seller as an additional insured or named insured in policies of Purchaser and/or the Facilities Owners. Seller agrees that it will reimburse Purchaser for its reasonable out-of-pocket expenses incurred in providing such assistance to Seller in obtaining tail coverage.

6.6    Reasonable Cooperation. Each Party agrees to use Commercially Reasonable Efforts to cooperate with the other Party to effect the consummation of the transactions contemplated by this Agreement, and to provide the other Party with such access or information related to the Facilities as may reasonably be requested in connection with such transactions.

6.7    Exclusivity. During the term of this Agreement, and except as necessary to fulfill its obligations under the Facilities Co-Tenancy Agreement, Seller will (a) deal exclusively with Purchaser and will not offer to sell, solicit offers to sell or negotiate with any third party for the sale of the Assets; and (b) promptly notify Purchaser of any unsolicited offer, interest or inquiry by a third party concerning a possible purchase of the Assets and will not provide any information with respect to a possible sale of the Assets to any third party.

6.8    Post Closing – Further Assurances. At any time or from time to time after the Closing, each Party will, upon the reasonable request of the other Party, execute and deliver any further instruments or documents, and exercise Commercially Reasonable Efforts to take such further actions as may reasonably be required to fulfill and implement the terms of this Agreement or realize the benefits intended to be afforded hereby. After the Closing, and upon prior reasonable request, each Party shall exercise Commercially Reasonable Efforts to cooperate with the other, at the requesting Party’s expense (but including only out-of-pocket expenses to third parties and not the costs incurred by any Party for the wages or other benefits paid to its officers, directors or employees), in furnishing non-privileged records, information, testimony and other assistance in connection with any inquiries, actions, audits, proceedings or disputes involving either of the Parties hereto (other than in connection with disputes between the Parties hereto) and based upon contracts, arrangements or acts of Seller, Purchaser, the other Facilities Owners or the Operating Agent on behalf of one or more of the Facilities Owners which were in effect or occurred on, prior to, or after Closing and which relate to the Assets, including, without limitation, arranging discussions with (and calling as a witness) officers, directors, employees, agents, and representatives of Purchaser or Seller.

6.9    Post Closing – Information and Records.

(a)    Following the Closing, Purchaser will not dispose of any books, records, documents or information reasonably relating to any Excluded Assets or Excluded Liabilities except in accordance with Purchaser’s existing record retention policies. During such period, Purchaser will permit Seller to examine and make copies, at Seller’s expense, of such books, records, documents and information for any reasonable purpose, including any litigation now pending or hereafter commenced by or against Seller, or the preparation of income or other Tax Returns. Seller will provide reasonable notice to Purchaser of its need to access such books, records, documents or other information.

(b)    Seller shall not be entitled to examine or copy privileged and/or attorney work product documents or information pursuant to Section 6.9(a). If privileged and/or attorney work product documents or information, including communications between Purchaser and its counsel, are disclosed to Seller in the books, records, documents or other information made available by Purchaser, Seller agrees (i) such disclosure is inadvertent, (ii) such disclosure will not

constitute a waiver, in whole or in part, of any privilege or work product, (iii) such information will be kept confidential, and (iv) Seller will promptly return to Purchaser (or will destroy or make inaccessible such information to the extent reasonably possible and certify as such to Purchaser) all copies of such books, records, documents or other information in the possession of Seller.

Purchaser represents and agrees that Purchaser expressly, unequivocally, and irrevocably waives its immunity from suit and consents to the dispute resolution mechanisms stated in this Agreement in accordance with the clear and express terms of this Agreement, to permit enforcement of the terms and conditions of this Agreement.

(i)    To the extent arbitration must be compelled, challenged, or sought to be enforced by a Party, Purchaser consents to such judicial proceedings in a New Mexico state court of competent jurisdiction as necessary to compel a Party’s participation in arbitration, a Party’s challenge of award, or a Party’s enforcement of an award.

(ii)    Seller may seek and obtain specific performance, money damages, injunctive relief, and any other remedies or relief from Purchaser, pursuant to and in accordance with the terms of this Agreement, and Seller may seek recourse and enforcement against any and all of the assets of Purchaser.

(iii)    Purchaser waives any benefits, rights, immunities, privileges, or limitations in applicable Navajo Nation Law that would otherwise foreclose specific performance, injunctive relief, money damages, or any other remedies or relief from Purchaser pursuant to this Agreement.

(iv)    Purchaser waives any otherwise existing right or claim of right to require exhaustion of tribal administrative or judicial remedies prior to exercise of the dispute resolution provisions of the Agreement, including with respect to arbitration and any ancillary litigation proceedings, to compel arbitration or enforce any arbitration award in a New Mexico state court of competent jurisdiction. Purchaser’s consent to the jurisdiction of a New Mexico state court of competent jurisdiction as provided in this Agreement is irrevocable. Purchaser waives any rights to have any dispute heard in a Navajo Nation tribunal, in any Navajo Nation administrative or judicial body whatsoever.

(v)    Purchaser agrees and expressly, unequivocally, and irrevocably waives its sovereign immunity, but only to Seller and its successors and assigns, and exclusively for the purposes of this Agreement, to have binding arbitration conducted in pursuant to and in accordance with the provisions of Section 11.10 of this Agreement.

(vi)    To the extent arbitration must be compelled, a Party challenges an arbitration award, or a Party seeks to enforce an arbitration award, pursuant to the terms of this Agreement, Purchaser clearly, expressly, unequivocally, and irrevocably consents to such judicial proceedings in a New Mexico state court of competent jurisdiction.

(vii)    Purchaser agrees and expressly, unequivocally, and irrevocably waives its sovereign immunity and any right otherwise existing, but only to Seller, and exclusively for the purposes of this Agreement, to have a dispute between the Parties pursuant to this Agreement heard in any Navajo Nation adjudicatory tribunal, forum, or other bodies that may otherwise have exclusive or concurrent jurisdiction over any such dispute, whether or not the same now exist or are hereinafter created.

(viii)    Purchaser agrees and expressly, unequivocally, and irrevocably waives its sovereign immunity, but only to Seller, and exclusively for the purposes of this Agreement, for recourse and enforcement against any and all of the assets of Purchaser only. Purchaser’s agreement and express, unequivocal, and irrevocable waiver of its sovereign immunity shall not be asserted, interpreted, or applied to permit or authorize the sale or transfer of any property held by the Navajo Nation apart from the Purchaser’s property, or any other property held by any other Navajo Nation instrumentality or entity other than Purchaser, whether such property is held in trust by the United States, or otherwise.

(ix)    Purchaser’s agreement and express, unequivocal, and irrevocable waiver of its sovereign immunity shall not apply, redound, or inure to any other third party (or non-Party) person or entity other than Seller and Seller’s successors and assigns, and authorizes only the remedies provided by this Agreement against Purchaser pursuant to only a claim, dispute, or cause of action brought by Seller against Purchaser to enforce Seller’s rights, and Purchaser’s obligations created and existing pursuant to this Agreement.

(x)    Purchaser clearly, expressly, unequivocally, and irrevocably waives its sovereign immunity for Seller’s disputes with Purchaser, Seller’s claims against Purchaser, or Seller’s causes of action against Purchaser, and only for Seller to enforce the rights of Seller and the obligations of Purchaser created and existing pursuant to this Agreement.

(xi)    Purchaser clearly, expressly, unequivocally, and irrevocably waives its sovereign immunity for Seller 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 Seller to obtain one or more of the following: (A) interpretation of this Agreement; (B) to make Purchaser perform a specific action Purchaser is obligated to perform pursuant to this Agreement, or to make Purchaser discontinue some specific action Purchaser is precluded from performing pursuant to this Agreement; or (C) to require Purchaser to comply with the duties and obligations clearly and expressly agreed to by Purchaser within this Agreement.

(xii)    Purchaser clearly, expressly, unequivocally, and irrevocably waives its sovereign immunity solely with respect to actions by Seller in accordance with the terms of this Agreement, and Purchaser’s limited waiver shall survive the termination or

expiration of this Agreement and remain effective until any applicable statute of limitations runs.

(xiii)    Purchaser represents and warrants that all of the persons creating and executing this Agreement, and any related agreements necessary to effectuate this Agreement, are actually, fully, properly, apparently, and impliedly authorized to vest all of the persons creating and executing this Agreement with all authorities necessary to bind and obligate Purchaser to the terms of this Agreement.

(xiv)    Purchaser clearly, expressly, unequivocally, and irrevocably agrees that, to the extent Purchaser changes its company, corporate, or organizational form, any resulting company, corporation, or organization will, by Navajo Nation Council resolution, or as otherwise required by the internal laws of the Navajo Nation, provide all of the same limited waivers of sovereign immunity to Seller as those set forth in this Section 6.10.

(xv)    Purchaser agrees that to the extent any provisions of this Agreement are rendered ineffective by any later changes in Navajo Nation Law, any such change shall constitute a breach of the agreement(s) and be actionable under the dispute resolution terms of this Agreement.

(xvi)    Purchaser agrees that the Navajo Nation’s independent covenant not to regulate any aspects of the Facilities, pursuant to the Facilities Lease, remains unchanged and unaffected.

(b)    No Waiver of Navajo Nation Sovereign Immunity. The Parties agree that nothing in this Agreement shall be asserted, interpreted, or otherwise understood to constitute any waiver of the Navajo Nation’s sovereign immunity, nor any waiver of any of the Navajo Nation’s rights, powers, or authorities as a sovereign governmental institution, whether express or implied.

(i)    The Parties agree that although Purchaser is a wholly-owned instrumentality of the Navajo Nation that otherwise possesses sovereign immunity, by virtue of its relationship to and with the Navajo Nation, Purchaser is a company with its own particular assets, liabilities, rights, and obligations.

(ii)    Purchaser’s limited waiver of sovereign immunity in this Agreement extends only to Seller, and only as described in this Agreement, and shall not be asserted, interpreted, implied or applied to permit or authorize the sale or transfer of any property held by the Navajo Nation apart from Purchaser’s property, whether such Navajo Nation property is held in trust for the Navajo Nation by the United States, or otherwise.

(iii)    Purchaser’s limited waiver of sovereign immunity shall not be asserted, interpreted, implied or applied to permit or authorize the sale or transfer of any property held by any Navajo Nation instrumentality, entity or enterprise other than Purchaser.

(iv)    Purchaser agrees that the Navajo Nation’s independent covenant not to regulate any aspects of the Facilities pursuant to the Facilities Lease remains unchanged

and unaffected. Because the Navajo Nation is not a party to this Agreement, this Agreement has no impact upon any existing contractual obligations of the Navajo Nation whatsoever.

6.11    Financial Assurances/Return on Equity/True-up Payments.

(a)    Financial Assurance. Purchaser has requested that Seller's Affiliate, Pinnacle West, provide a financial assurance on Purchaser's behalf consistent with the Four Corners Financial Assurance Policy and in a form acceptable to the other Facilities Owners (the "Financial Assurance").   Purchaser acknowledges that the Financial Assurance will not absolve Purchaser of primary liability for all obligations Purchaser will have under the Facilities Contracts from and after the Closing.  Without limiting the generality of the foregoing, Purchaser agrees that nothing herein or in the Financial Assurance shall amend or alter (i) any of Purchaser's obligations as a Facilities Owner to timely meet and abide by all the obligations of the Facilities Owners under the Facilities Contracts and (ii) the application and enforcement, as to Purchaser,  of the provisions of Section 20 and any other provision of the Facilities Co-Tenancy Agreement relating to a default.   Any payment by Pinnacle West on account of the Financial Assurance shall be deemed a default by Purchaser under the Facilities Co-Tenancy Agreement, with all of the resulting consequences of a default, which default will be cured only if Pinnacle West is made whole on the amount so paid within three (3) Business Days following the default.

(b)    Security for Financial Assurance.  To induce Pinnacle West to provide the Financial Assurance, Purchaser has agreed to provide as security for Purchaser’s repayment obligations the same collateral as described in the Collateral Assignment. The foregoing commitment of Purchaser to repay Pinnacle West, and the security backing such commitment, shall be set forth in a separate agreement between Purchaser and Pinnacle West that is in a form acceptable to Pinnacle West and Purchaser (the “Agreement to Provide Financial Assurance”).  Anything to the contrary in the Agreement to Provide Financial Assurance notwithstanding, in the event of any payment by Pinnacle West made on behalf of Purchaser pursuant to the Financial Assurance, Purchaser shall at all times remain responsible to immediately reimburse and indemnify Pinnacle West for all such amounts paid by it on account of the Financial Assurance.

(c)    Release of Collateral. Following payment in full of the Note, and provided that Purchaser is not then in default under the Agreement to Provide Financial Assurance or any documents or instruments related thereto, Purchaser shall have the right to seek to independently satisfy the Four Corners Financial Assurance Policy. If Purchaser is able to independently satisfy the Four Corners Financial Assurance Policy and posts the requisite financial assurance, then Pinnacle West shall release the collateral described in Section 6.11(b).

(d)    Post-Closing Amendments to Facilities Co-Tenancy Agreement.  Purchaser agrees that as promptly as practicable, and in any event within sixty (60) days following the Effective Date, Purchaser shall enter into an amendment to the Facilities Co-Tenancy Agreement acknowledging for the benefit of all Facilities Owners the matters described in Section 6.11(a), including the consequences of Purchaser's defaults.

(e)    Return on Equity/True-up Payments. Simultaneous with the Closing, Seller shall cancel, forgive, and forever discharge any and all right to the return on equity component of

the Calendar Year 2018 True-Up Payment (for the avoidance of doubt, Purchaser remains responsible for the Calendar Year 2018 True-Up Payment with the assumption that the Target ROE will be 0% rather than 15%). The Parties agree that the Calendar Year 2017 True-Up Payment will be calculated in accordance with the 2016 Coal Supply Agreement and not be discounted. The Parties further agree that, unless and until an objection is raised by Purchaser in accordance with the terms of the 2016 Coal Supply Agreement, the Calendar Year 2017 True-Up Payment and the Calendar Year 2018 True-Up Payment calculations will be deemed presumptively correct and payable when due by Purchaser; provided, however, Purchaser shall retain the right to audit and, if it deems necessary, dispute any True-Up Payment based solely on audit findings, which audits must be completed on or before the first anniversary after such payment becomes due. As used in this Section 6.11(e), (i) “Calendar Year 2016 True-Up Payment” means the True-Up Payment for the period beginning on July 7, 2016 and ending on December 31, 2016, which was paid by Purchaser on December 17, 2017; (ii) “Calendar Year 2017 True-Up Payment” means the True-Up Payment for the 2017 calendar year to be paid by Purchaser to Seller pursuant to the 2016 Coal Supply Agreement on December 31, 2018; (iii) “Calendar Year 2018 True-Up Payment” means the True-Up Payment for that portion of the 2018 calendar year between January 1, 2018 and the Effective Date to be paid by Purchaser to Seller pursuant to the 2016 Coal Supply Agreement on December 31, 2019; (iv) “Target ROE” has the meaning set forth in Section 6.9 of the 2016 Coal Supply Agreement; and (v) “True-Up Payment” has the meaning set forth in Section 3 of Exhibit 6.9(a) of the 2016 Coal Supply Agreement.

(f)    Post-Execution/Pre-Closing True-Up Payments. In the event that the Closing Date is after July 1, 2018, Purchaser shall be responsible payment of the True-Up Payments as set forth in Section 6.9 of the 2016 Coal Supply Agreement for the period of time between July 1, 2018 and the Closing Date or termination of this Agreement pursuant to Section 10.1 (“True-Up Payment Continuation Period”), provided, however, that during the True-Up Payment Continuation Period, if any, Seller shall forgive and waive any and all right to the return on equity component of the True-Up Payment attributable to the True-Up Payment Continuation Period (for the avoidance of doubt, Purchaser shall be responsible for payment of the True-Up Payment for the True-Up Payment Continuation Period pursuant to the procedure set forth in Section 6.9 of the 2016 Coal Supply Agreement, except that the Target ROE will be 0% rather than 15%, and notwithstanding the fact that the Parties shall have executed the Amended and Restated 2016 Coal Supply Agreement).

6.12    Pension and OPEB Liabilities. Seller shall cause Pinnacle West to enter into a letter agreement (the “Side Letter”) with Purchaser, in form reasonably satisfactory to Pinnacle West and Purchaser, to the effect that if, at the end of life of the Plant, Pinnacle West determines that the Pension and OPEB Liabilities allocable to the Facilities are underfunded, then Pinnacle West shall pay and indemnify Purchaser for its share thereof attributable to the EPE Interest.

7.1    Indemnification by Seller.

(a)    Purchaser Claims. From and after the Closing, Seller will indemnify, defend and hold harmless Purchaser and its Affiliates, and each of their officers, directors, employees, attorneys, agents and successors and assigns (collectively, the “Purchaser Group”), from and against any and all demands, suits, penalties, obligations, damages, claims, losses, liabilities, payments, costs and expenses (including reasonable legal, accounting and other expenses in connection therewith) (collectively, “Damages”), and including costs and expenses incurred in connection with investigations, and settlement proceedings arising out of, with respect to or by reason of, the following (collectively, “Purchaser Claims”):

(i)    any breach or violation of any covenant or agreement of Seller set forth in this Agreement;

(ii)    any breach or inaccuracy of the representations or warranties made by Seller contained in this Agreement in Article 4;

(iii)    the Excluded Liabilities; and

(iv)    any loss or damages resulting from or arising out of Seller’s ownership of the Assets prior to Closing, except for any loss or damage resulting from or arising out of (x) Assumed Liabilities or (y) any Taxes payable by Purchaser pursuant to this Agreement.

(b)    SELLER LIMITATIONS. IF THE CLOSING OCCURS, THE PURCHASER GROUP WILL NOT BE ENTITLED TO ANY PUNITIVE, INCIDENTAL, INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES RESULTING FROM OR ARISING OUT OF ANY PURCHASER CLAIMS, INCLUDING DAMAGES FOR LOST REVENUES, INCOME, PROFITS OR TAX BENEFITS, DIMINUTION IN VALUE OF THE FACILITIES, OR ANY OTHER DAMAGE OR LOSS RESULTING FROM THE DISRUPTION TO OR LOSS OF OPERATION OF THE ASSETS, EXCEPT TO THE EXTENT DUE ON ANY THIRD PARTY CLAIM.

7.2    Indemnification by Purchaser.

(a)    Seller Claims. From and after the Closing, Purchaser will indemnify, defend and hold harmless Seller and its Affiliates and each of their officers, directors, employees, attorneys, agents and successors and assigns (collectively, the “Seller Group”), from and against any and all Damages, and including costs and expenses incurred in connection with, investigations and settlement proceedings arising out of, with respect to or by reason of the following (collectively, “Seller Claims”):

(i)    any breach or violation of any covenant or agreement of Purchaser set forth in this Agreement;

(ii)    any breach or inaccuracy of any of the representations or warranties made by Purchaser contained in this Agreement in Article 5;

(iii)    the Assumed Liabilities; and

(iv)    any loss or damages resulting from or arising out of Purchaser’s ownership or operation of the Assets from and after the Closing, except for any loss or damage resulting from or arising out of (x) Excluded Liabilities or (y) any Taxes payable by Seller pursuant to this Agreement.

(b)    PURCHASER LIMITATIONS. IF THE CLOSING OCCURS, THE SELLER GROUP WILL NOT BE ENTITLED TO ANY PUNITIVE, INCIDENTAL, INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES RESULTING FROM OR ARISING OUT OF ANY SELLER CLAIM, INCLUDING DAMAGES FOR LOST REVENUES, INCOME, PROFITS OR TAX BENEFITS, DIMINUTION IN THE VALUE OF THE FACILITIES OR ANY OTHER DAMAGE OR LOSS RESULTING FROM THE DISRUPTION TO OR LOSS OF OPERATION OF THE ASSETS, EXCEPT TO THE EXTENT DUE ON ANY THIRD PARTY CLAIM.

7.3    Notice of Claim. Subject to the terms of this Agreement and upon a Party’s receipt of notice of the assertion of a claim or of the commencement of any suit, action or proceeding made or brought by any Person who is not a Party to this Agreement or an Affiliate, the Party seeking indemnification hereunder (the “Indemnitee”) will promptly notify the Party against whom indemnification is sought (the “Indemnitor”) in writing of any damage, claim, loss, liability or expense which the Indemnitee has determined has given or could give rise to a claim under Section 7.1 or Section 7.2. (The written notice is referred to as a “Notice of Claim.”) A Notice of Claim will specify, in reasonable detail, the facts known to the Indemnitee regarding the claim. Subject to the terms of this Agreement, the failure to provide (or timely provide) a Notice of Claim will not affect the Indemnitee’s rights to indemnification except to the extent such failure shall have materially and adversely prejudiced Indemnitor.

7.4    Defense of Third Party Claims. The Indemnitor will defend, in good faith and at its expense, any claim or demand set forth in a Notice of Claim relating to a Third Party Claim and the Indemnitee, at its expense, may participate in the defense and employ, at its expense, separate counsel of its choice for such purpose. The Indemnitee cannot settle or compromise any Third Party Claim so long as the Indemnitor is defending it in good faith. If the Indemnitor elects not to contest a Third Party Claim, the Indemnitee may undertake its defense, and the Indemnitor will be bound by the result obtained by the Indemnitee. The Indemnitor may at any time request the Indemnitee to agree to the abandonment of the contest of the Third Party Claim or to the payment or compromise by the Indemnitor of the asserted claim or demand. If the Indemnitee does not object in writing within fifteen (15) days of the Indemnitor’s request, the Indemnitor may proceed with the action stated in the request. If within that fifteen (15) day period the Indemnitee notifies the Indemnitor in writing that it has determined that the contest should be continued, the Indemnitor will be liable under this Article 7 only for an amount up to the amount which the third party to the contested Third Party Claim had agreed to accept in payment or compromise as of the time the Indemnitor made its request. This Section 7.4 is subject to the rights of any Indemnitee’s insurance carrier that is defending the Third Party Claim.

7.5    Control of Litigation.

(a)    The Parties acknowledge and agree that, from and after the Effective Date, as between Seller and Purchaser, Seller shall be entitled exclusively to control, defend and settle any suit, action, proceeding or investigation arising out of or related to any Excluded Assets, Excluded Liabilities or Taxes for Pre-Closing Tax Periods, in each case, not involving claims against the Operating Agent or the other Facilities Owners, and Purchaser agrees to cooperate reasonably in connection therewith, it being understood that Purchaser shall not be required to incur any cost in connection with any such settlement but may be required to provide a release to a third party claimant in respect of the specific matters involved in such suit, action, proceeding or investigation; provided, however, that Seller shall reimburse Purchaser for all reasonable costs and expenses incurred in providing such cooperation to Seller.

(b)    The Parties acknowledge and agree that, from and after the Effective Date, as between Seller and Purchaser, Purchaser shall be entitled exclusively to control, defend and settle any suit, action, proceeding or investigation arising out of or related to any Assets or Assumed Liabilities, in each case, not involving Excluded Assets, Excluded Liabilities or Taxes for Pre-Closing Tax Periods, and Seller agrees to cooperate reasonably in connection therewith, it being understood that Seller shall not be required to incur any cost in connection with any such settlement but may be required to provide a release to a third party claimant in respect of the specific matters involved in such suit, action, proceeding, or investigation; provided, however, that Purchaser shall reimburse Seller for all reasonable costs and expenses incurred in providing such cooperation to Purchaser and shall not unreasonably interfere with Seller’s operations. The foregoing provisions of this Section 7.5(b) shall not apply to the Arbitration.

(c)    For suits, actions, proceedings, or investigations arising out of or related to both Excluded Assets and/or Excluded Liabilities (other than Taxes), and Assets and/or Assumed Liabilities, the Parties agree to coordinate with each other with respect to the defense thereof. Without limiting the foregoing, for suits, actions, proceedings or investigations in which Seller and Purchaser are named parties, Seller and Purchaser shall discuss the feasibility of having one counsel represent Seller and Purchaser.

7.6    Direct Claim Procedures. In the event Indemnitee has a claim for indemnity under Section 7.1 or 7.2 against Indemnitor that does not involve a Third Party Claim, Indemnitee agrees to promptly deliver a Notice of Claim to Indemnitor. The Notice of Claim will specify, in reasonable detail, the facts known to the Indemnitee regarding the claim. Subject to the terms of this Agreement, the failure to provide (or timely provide) a Notice of Claim will not affect the Indemnitee’s rights to indemnification except to the extent such failure shall have materially and adversely prejudiced Indemnitor. If the Indemnitor does not notify the Indemnitee within thirty (30) days following the receipt of a Notice of Claim that the Indemnitor disputes its indemnity obligation to the Indemnitee with respect to such claim, such claim shall be conclusively deemed a liability of the Indemnitor and the Indemnitor shall promptly pay to the Indemnitee any and all damages arising out of such claim. If the Indemnitor has timely disputed its indemnity obligation with respect to such claim, the Parties shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved pursuant to Section 11.10.

7.7    Cooperation. The Party defending the Third Party Claim will (a) consult with the other Party throughout the pendency of the Third Party Claim regarding the investigation, defense, settlement, trial, appeal or other resolution of the Third Party Claim; and (b) afford the other Party the opportunity to be associated in the defense of the Third Party Claim. The Parties will cooperate in the defense of the Third Party Claim. The Indemnitee will make available to the Indemnitor or its representatives all records and other materials reasonably required by them for use in contesting any Third Party Claim (subject to obtaining an agreement to maintain the confidentiality of confidential or proprietary materials in a form reasonably acceptable to Indemnitor and Indemnitee). If requested by the Indemnitor, the Indemnitee will cooperate with the Indemnitor and its counsel in contesting any Third Party Claim that the Indemnitor elects to contest or, if appropriate, in making any counterclaim against the Person asserting the claim or demand, or any cross-complaint against any Person. The Indemnitor will reimburse the Indemnitee for any expenses incurred by Indemnitee in cooperating with or acting at the request of the Indemnitor.

7.8    Mitigation and Limitation on Claims. As used in this Agreement, the term “Indemnifiable Claim” means any Purchaser Claims or Seller Claims. Notwithstanding anything to the contrary contained herein:

(a)    Reasonable Steps to Mitigate. The Indemnitee will take all reasonable steps to mitigate all losses, damages and the like relating to an Indemnifiable Claim, including availing itself of any defenses, limitations, rights of contribution, claims against third Persons and other rights at law or equity, and will provide such evidence and documentation of the nature and extent of the Indemnifiable Claim as may be reasonably requested by the Indemnitor. The Indemnitee’s reasonable steps include the reasonable expenditure of money to mitigate or otherwise reduce or eliminate any loss or expense for which indemnification would otherwise be due under this Article 7, and the Indemnitor will reimburse the Indemnitee for the Indemnitee’s reasonable expenditures in undertaking the mitigation, together with, interest thereon from the date of payment to the date of repayment at the “prime rate” as published in The Wall Street Journal, Eastern Edition.

(b)    Actual Damages. Any Indemnifiable Claim is limited to the amount of actual damages sustained by the Indemnitee by reason of such breach or nonperformance.

(c)    Minimum Claim. No Party shall have any liability or obligation to indemnify under Section 7.1(a)(ii) or Section 7.2(a)(ii), as the case may be, unless the aggregate amount for which such Party would be liable thereunder, but for this provision, exceeds One Hundred Fifty Thousand Dollars ($150,000), and recovery shall be limited only to such amounts as exceed One Hundred Fifty Thousand Dollars ($150,000). For purposes of the foregoing, individual claims of Fifteen Thousand Dollars ($15,000) or less shall not be aggregated for purposes of calculating such deductible threshold amount or for calculating damages in excess of such amount. Nothing in this Section 7.8 is intended to modify or limit a Party’s liability or obligation hereunder for other Indemnifiable Claims or to constitute an assumption by Purchaser of any Excluded Liability or an assumption by Seller of any Assumed Liability.

7.9    Exclusivity. Except as specifically set forth in this Agreement, and except for intentional fraud, following the Closing, the rights and remedies of Seller Group, on the one hand, and Purchaser Group, on the other hand, for money damages under this Article 7 are, solely as

between Seller Group on the one hand and Purchaser Group on the other hand, exclusive and in lieu of any and all other rights and remedies for money damages which each of Seller on the one hand, and Purchaser on the other hand, may have under this Agreement under applicable Law with respect to any Indemnifiable Claim, whether at common law or in equity.

The obligations of Purchaser under this Agreement to complete the purchase of the Assets and assume the Assumed Liabilities are subject to the satisfaction or waiver, or deemed satisfaction or waiver, on or prior to the Closing, of each of the following conditions precedent:

11.6    Severability. If any provision hereof is held invalid or unenforceable by any arbitrator or as a result of future legislative action, this holding or action will be strictly construed and will not affect the validity or effect of any other provision hereof, so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such a determination, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible. To the extent permitted by law, the Parties waive, to the maximum extent permissible, any provision of law that renders any provision hereof prohibited or unenforceable in any respect.

11.7    Assignability. This Agreement is not assignable by either Party without the prior written consent of the other Party, which may be provided or denied in the sole discretion of the non-assigning party, and no assignment shall relieve the assigning Party of any of its obligations

hereunder. This Agreement is binding upon and inures to the benefit of the successors and permitted assigns of the Parties.

The Parties agree to try to resolve any disputes through negotiations. If the matter is not resolved through such negotiations, the matter shall be submitted to binding arbitration, as set forth below.

(c)    Binding Arbitration. In the event negotiations between the Parties do not result in resolution of the Parties’ dispute(s), the Parties shall submit to binding arbitration conducted pursuant to the American Arbitration Association’s (“AAA”) Commercial Arbitration Rules and the Delaware Uniform Arbitration Act, with substantive resolution of disputes governed by the contract and commercial laws of the State of Delaware, subject to and conditioned by the following:

(i)    Arbitration Notice. The demanding Party (the “Claimant”) shall provide a notice of arbitration (the “Arbitration Notice”) to the other Party to the dispute (the “Respondent”), which shall include: (A) the designation of such Party’s arbitrator; and (B) a reasonably detailed statement of the facts and theories supporting that Party’s claims. Within this same period, the Claimant shall provide a copy of the Arbitration Notice to the Respondent in accordance with the notice provisions of Section 11.11 of this Agreement.

(ii)    Response to Arbitration Notice.

In the event the two (2) Party arbitrators cannot agree on a third arbitrator, the AAA shall select a third arbitrator from its National Roster, who shall be free of any association of any kind with either Party and whose participation as an arbitrator shall not otherwise constitute a conflict of interest or give rise to an appearance of impropriety. The arbitrators shall be bound by, and strictly adhere to the AAA’s Code of Ethics for Arbitration in Commercial Disputes, with particular attention to Canon IX.

(iv)    Expenses of Arbitration. Each Party shall pay the costs, fees and expenses of its appointed arbitrator, and the Parties shall each pay one-half of the third arbitrator’s costs, fees, and expenses, to conduct the arbitral hearing or proceeding.

(v)    Arbitration Panel and Arbitrator Authority to Issue Interim Exigent Equitable Relief. Unless agreed to otherwise, the Parties shall request that the arbitrators commence the final arbitration hearing concerning all claims asserted in the Arbitration Notice, any amendments thereto and any counterclaims asserted in the Response thereto, within one hundred eighty (180) days of the date of the service of the Arbitration Notice, unless the arbitration panel determines that additional time is appropriate to ensure a fair hearing. The arbitration panel shall have authority to issue interim/equitable relief prior to the final hearing, including the authority to direct discovery (and, in that regard, the Parties agree that written discovery and depositions of fact and expert witnesses shall be permitted), specific performance and injunctive relief during the pendency of the dispute resolution proceedings provided by this Agreement.

(vi)    Location. The arbitration shall be conducted at a mutually-agreed-upon location, which shall be any of the following cities: Shiprock, Navajo Nation; Farmington, New Mexico; Albuquerque, New Mexico; or Phoenix, Arizona.

(vii)    Award and Enforcement.

The arbitration panel is authorized to award monetary damages and equitable relief (specific performance and injunctive (preliminary and permanent) and declaratory relief), if such relief, in their opinion, is appropriate. In any arbitration, each Party shall bear its own costs, expenses, and attorneys’ fees, unless the arbitration panel orders otherwise.

(d)    Actions to Compel Arbitration, for Equitable Relief, and for Enforcement of Arbitration Provisions or an Arbitral Award

(i)    Forum. The Judicial District Court of the State of New Mexico, or if the First Judicial District Court lacks proper jurisdiction pursuant to a change in law or the First Judicial District Court is otherwise unavailable to the Parties, then the Delaware Courts of Chancery, shall have exclusive jurisdiction to compel the Parties’ participation in binding arbitration pursuant to this Agreement, enforce an arbitral award, and grant any exigent equitable relief necessary to maintain the status quo, during the pendency of the arbitration.

(ii)    Limitations on Judicial Review. The Parties’ enforcement of an arbitral award shall be limited to the remedy/award issued by the arbitration panel, and shall only be enforceable by the First Judicial District Court of the State of New Mexico, or where the First Judicial District Court lacks proper jurisdiction as a result of a change in law, or the First Judicial District Court is otherwise unavailable to the Parties, then the Delaware Courts of Chancery. Neither Party shall petition, move, or otherwise request the First Judicial District Court of the State of New Mexico or the Delaware Courts of Chancery to conduct a de novo review of the matter in dispute, issues in dispute, evidence presented by the Parties or considered by the arbitration panel, or the remedy/award issued by the arbitration panel. Neither the First Judicial District Court of the State of New Mexico nor the Delaware Courts of Chancery may conduct a de novo review of any matter in dispute, any issues, any evidence, or any remedy/award issued by the arbitration panel. Rather, any judicial review of an arbitral award shall be strictly limited in the manner prescribed by the Delaware Uniform Arbitration Act. The Parties understand and acknowledge that the First Judicial District Court of New Mexico, or if the First Judicial District Court lacks proper jurisdiction pursuant to a change in law, or the First Judicial District Court is otherwise unavailable to the Parties, then the Delaware Courts of Chancery also have the authority to compel arbitration, hear and decide challenges of arbitral awards, and enforce arbitral awards.

(iii)    Choice of Law. Without regard to any choice of law or conflicts of laws principles or provisions prohibiting application of the law of the State of Delaware whether in the context of an arbitral proceeding provided by this Agreement, or as a result of any judicial action to compel arbitration, challenge an arbitral award, or to enforce an arbitral award, the Delaware Uniform Arbitration Act, the laws of the State of Delaware, and the AAA’s Commercial Arbitration Rules shall govern the resolution of any dispute(s) between the Parties arising out of, pursuant to, or in connection with this Agreement.

(d)    The “Coal Purchase Test” will be satisfied if the aggregate coal purchases made by all parties under the CSA for the three full calendar months immediately prior to the month for which the Monthly Installment is due cumulatively equal or exceed 900,000 tons.

(e)    By way of example, with respect to the Monthly Installment due February 15, 2019, if the aggregate coal purchases made by all parties under the CSA from November 1, 2018 through January 31, 2019 are less than 900,000 tons, then that Monthly Installment is deferred until, and shall be paid (together with interest at the Base Rate from February 15, 2019), July 24, 2019.

2.3    Interest.

(a)    The Note shall bear interest on the unpaid principal amount thereof (including, to the extent permitted by law, on interest thereon not paid when due) from the date made until paid in full in cash at the rate of 3.9% per annum, compounded monthly (the “Base Rate”). All interest charges shall be computed on the basis of a year of three hundred sixty (360) days.

(b)    If any Default or Event of Default occurs and is continuing, then, while any such Default or Event of Default is continuing, the entire unpaid principal balance and accrued interest under the Note shall bear interest to the extent permitted by law at the Base Rate plus 8% per annum (the “Default Rate”). Interest at the Default Rate shall be payable monthly on the first day of each month until all amounts due under the Note have been paid in full.

2.4    Maturity Date; Prepayments. Borrower shall repay all remaining outstanding Obligations on the Stated Maturity Date. Borrower may prepay any amounts due to Lender hereunder at any time or from time to time without premium or penalty upon five (5) days’ advance notice to Lender.

2.5    Payments by Borrower.

(a)    All payments to be made by Borrower shall be made without set-off, recoupment or counterclaim of any kind. Except as otherwise expressly provided in this Agreement, all payments by Borrower shall be made to Lender at the account designated by Lender and shall be made in United States dollars and in immediately available funds, no later than 12:00 noon (Phoenix, Arizona time) on the date specified herein. Any payment received by Lender later than 12:00 noon (Phoenix, Arizona time) shall be deemed to have been received on the following Business Day and any applicable interest shall continue to accrue.

(b)    Whenever any payment is due on a day other than a Business Day, such payment may be made on the next ensuing Business Day with effect as though payment were made on the due date, and, if such payment is made, no additional interest shall accrue from and after such due date.

2.6    Indemnity for Returned Payments. If after receipt of any payment which is applied to the payment of all or any part of the Obligations, Lender is for any reason compelled to surrender

such payment or proceeds to any Person because such payment or application of proceeds is invalidated, declared fraudulent, set aside, determined to be void or voidable as a preference, impermissible set-off, or a diversion of trust funds, or for any other reason, then the Obligations or part thereof intended to be satisfied shall be revived and continued and this Agreement shall continue in full force as if such payment or proceeds had not been received by Lender, and Borrower shall be liable to pay to Lender, and hereby does indemnify Lender and hold Lender harmless for the amount of such payment or proceeds surrendered. The provisions of this Section 2.6 shall be and remain effective notwithstanding any contrary action which may have been taken by Lender in reliance upon such payment or application of proceeds, and any such contrary action so taken shall be without prejudice to Lender’s rights under this Agreement and shall be deemed to have been conditioned upon such payment or application of proceeds having become final and irrevocable. The provisions of this Section 2.6 shall survive the termination of this Agreement.

Borrower makes the following representations and warranties to Lender:

3.1    Organization; Qualification. Borrower is a limited liability company, duly organized, validly existing and in good standing under the laws of the Navajo Nation and has all requisite limited liability company power and authority to own, lease and operate its properties and to carry on its business as is now being conducted.

3.2    Authorization; Enforceability. Borrower has full limited liability company power to enter into, and carry out its obligations under, this Agreement and the other Loan Documents and to consummate the transactions contemplated hereby and thereby. The execution, delivery and performance of this Agreement and the other Loan Documents, and the consummation of the transactions contemplated hereby and thereby, have been duly and validly authorized by all necessary limited liability company action required on the part of Borrower and no other limited liability company proceedings on the part of Borrower are necessary to authorize this Agreement and the other Loan Documents or to consummate the transactions contemplated hereby and thereby. Assuming Lender’s due authorization, execution and delivery of this Agreement and the other Loan Documents when executed by Lender, this Agreement does and the other Loan Documents when executed by Borrower, will constitute the valid and legally binding obligations of Borrower, enforceable against Borrower in accordance with its and their terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws of general application relating to or affecting the enforcement of creditors’ rights and by general equitable principles.

3.3    No Violation of Laws or Agreements; Consents. Neither the execution and delivery of this Agreement or any of the other Loan Documents, nor the compliance with any provision hereof or thereof, nor the consummation of the transactions contemplated hereby or thereby will:

(a)    violate, or conflict with, or result in a breach of any provisions of the Operating Agreement or the other organizational documents of Borrower;

(b)    result in a default (or give rise to any right of termination, cancellation or acceleration) under or conflict with any of the terms, conditions or provisions of any material note, bond, mortgage, indenture, license, or agreement or other instrument or obligation to which Borrower is a party or by which Borrower may be bound, except for such defaults (or rights of termination or acceleration) as to which requisite waivers or consents have been, or prior to the Closing Date will have been, obtained;

(c)    violate any law, rule, regulation, order, writ, injunction, or decree, applicable to Borrower or any of its assets, except where such violations, individually or in the aggregate will not affect the validity or enforceability of this Agreement or the other Loan Documents or the validity of the transactions contemplated hereby or thereby; or

(d)    require consent or approval of, filing with, or notice to any Person which, if not obtained would prevent Borrower from performing its obligations hereunder.

Borrower covenants and agrees that, so long as the Loan remains outstanding and until the Note has been paid in full and all of Borrower’s Obligations under the Loan Documents have been fully discharged, unless Lender shall otherwise consent in writing:

4.1    Existence and Good Standing. Borrower shall maintain its limited liability company existence and its qualifications and good standing in all jurisdictions wherein the character of the properties owned or leased by it or the nature of the activities conducted by it makes such qualifications and good standing necessary.

4.2    Compliance with Law and Agreements; Maintenance of Licenses. Borrower shall comply in all respects with all requirements of Law of any Governmental Authority having jurisdiction over it or its Business. Borrower shall obtain and maintain all licenses, permits, franchises, and governmental authorizations necessary to own its property and to conduct its Business as conducted on the Closing Date or as proposed to be conducted.

4.3    Maintenance of Property; Insurance. Borrower shall maintain all of its property necessary and useful in the conduct of its Business, in good operating condition and repair, ordinary wear and tear excepted, and shall continue in full force and effect all existing insurance policies.

4.4    Books and Records. Borrower shall maintain, in a safe place, proper and accurate books, ledgers, correspondence and other records relating to its operations and Business. Lender shall have the right, from time to time, and upon reasonable notice during normal business hours, to examine and audit and to make abstracts from and photocopies of Borrower’s books, ledgers, correspondence and other records.

4.5    Taxes and Other Obligations. Borrower shall pay all of its current obligations before they become delinquent, including all tribal, federal, state and local taxes, assessments, levies and governmental charges and all other payments required under any Law; provided, however, that Borrower need not pay any tax, assessment, governmental charge or other obligation that (a) it is

contesting in good faith by appropriate proceedings diligently pursued, and (b) it has established proper reserves for such non-payment as provided in GAAP.

4.6    Mergers, Consolidations or Sales. Borrower shall not enter into any merger, consolidation or other reorganization, with the exception of conversion to a corporation pursuant to the Act of June 18, 1934 (48 Stat. 984), as amended, 25 U.S.C. § 5124, or cease or suspend its Business, or take any steps in contemplation of dissolution, or sell, lease, transfer, assign or dispose of all or substantially all of its assets, or enter into any transaction except in the ordinary course of Borrower’s Business.

4.7    Limitations on Liens. Borrower will not create or incur, or suffer to be incurred or to exist, any Lien on the Collateral except: (a) Liens for property taxes, assessments or other governmental charges or levies, and Liens securing claims or demands of mechanics and materialmen, provided that payment thereof is not at the time required by Section 4.5; or (b) Liens created pursuant to this Agreement.

4.8    Business Conducted. Borrower shall not engage directly or indirectly in any line of business other than related to the production, generation, storage and transmission of energy resources and the exploration, production, and extraction of energy fuels and hydrocarbon byproducts as permitted by Borrower’s organizational documents.

4.9    Further Assurances. Borrower shall execute and deliver to Lender such documents and agreements, and shall take or cause to be taken such actions, as Lender may, from time to time, reasonably request to carry out the terms and conditions of this Agreement and the other Loan Documents.

4.10    Waiver of Sovereign Immunity.

(a)    General. The Parties agree that this Agreement is fully enforceable between them. Borrower agrees to waive and hereby waives its sovereign immunity, to the extent necessary to make this Agreement and the Loan Documents enforceable as to Lender. Therefore, Borrower clearly, expressly, unequivocally, and irrevocably, waives its sovereign immunity for purposes of this Agreement, and in accordance with and as limited by, the terms of this Agreement.

(b)    Limited Waiver of Borrower’s Sovereign Immunity. Borrower limitedly waives its sovereign immunity from suit in accordance with and for the limited purposes described in this Section 4.10, namely for litigation or to enforce an order or judgment in litigation pursuant to the terms and provisions of this Agreement, including Section 8.9 hereof, or for exigent or emergency equitable relief. Borrower represents and agrees that Borrower expressly, unequivocally, and irrevocably waives its immunity from suit and consents to the dispute resolution mechanisms stated in this Agreement in accordance with the clear and express terms of this Agreement, to permit enforcement of the terms and conditions of this Agreement.

(i)    To the extent litigation must be compelled, challenged, or sought to be enforced by a Party, Borrower consents to such judicial proceedings in a New Mexico state

court of competent jurisdiction as necessary to compel a Party’s participation in litigation, a Party’s challenge of an order or judgment, or a Party’s enforcement of a judgment.

(ii)    Lender may seek and obtain specific performance, money damages, injunctive relief, and any other remedies or relief from Borrower, pursuant to and in accordance with the terms of this Agreement, and Lender may seek recourse and enforcement against any and all of the assets of Borrower.

(iii)    Borrower waives any benefits, rights, immunities, privileges, or limitations in applicable Navajo Nation Law that would otherwise foreclose specific performance, injunctive relief, money damages, or any other remedies or relief from Borrower pursuant to this Agreement.

(iv)    Borrower waives any otherwise existing right or claim of right to require exhaustion of tribal administrative or judicial remedies prior to exercise of the dispute resolution provisions of the Agreement, including with respect to litigation proceedings or to enforce any order or judgment award in a New Mexico state court of competent jurisdiction. Borrower’s consent to the jurisdiction of a New Mexico state court of competent jurisdiction as provided in this Agreement is irrevocable. Borrower waives any rights to have any dispute heard in a Navajo Nation tribunal, in any Navajo Nation administrative or judicial body whatsoever.

(v)    Borrower agrees and expressly, unequivocally, and irrevocably waives its sovereign immunity, but only to Lender and its successors and assigns, and exclusively for the purposes of this Agreement, to have litigation conducted pursuant to and in accordance with the provisions of Section 8.9 of this Agreement.

(vi)    To the extent litigation must be compelled, a Party challenges a litigation order or judgment, or a Party seeks to enforce a litigation order or judgment, pursuant to the terms of this Agreement, Borrower clearly, expressly, unequivocally, and irrevocably consents to such judicial proceedings in a New Mexico state court of competent jurisdiction.

(vii)    Borrower agrees and expressly, unequivocally, and irrevocably waives its sovereign immunity and any right otherwise existing, but only to Lender, and exclusively for the purposes of this Agreement, to have a dispute between the Parties pursuant to this Agreement heard in any Navajo Nation adjudicatory tribunal, forum, or other bodies that may otherwise have exclusive or concurrent jurisdiction over any such dispute, whether or not the same now exist or are hereinafter created.

(viii)    Borrower agrees and expressly, unequivocally, and irrevocably waives its sovereign immunity, but only to Lender, and exclusively for the purposes of this Agreement, for recourse and enforcement against any and all of the assets of Borrower only. Borrower’s agreement and express, unequivocal, and irrevocable waiver of its sovereign immunity shall not be asserted, interpreted, or applied to permit or authorize the sale or transfer of any property held by the Navajo Nation apart from the Borrower’s property, or any other property held by any other Navajo Nation instrumentality or entity other than Borrower, whether such property is held in trust by the United States, or otherwise.

(ix)    Borrower’s agreement and express, unequivocal, and irrevocable waiver of its sovereign immunity shall not apply, redound, or inure to any other third-party (or non-Party) person or entity other than Lender and Lender’s successors and assigns, and authorizes only the remedies provided by this Agreement against Borrower pursuant to only a claim, dispute, or cause of action brought by Lender against Borrower to enforce Lender’s rights, and Borrower’s obligations created and existing pursuant to this Agreement.

(x)    Borrower clearly, expressly, unequivocally, and irrevocably waives its sovereign immunity for Lender’s disputes with Borrower, Lender’s claims against Borrower, or Lender’s causes of action against Borrower, and only for Lender to enforce the rights of Lender and the obligations of Borrower created and existing pursuant to this Agreement.

(xi)    Borrower clearly, expressly, unequivocally, and irrevocably waives its sovereign immunity for Lender to seek to obtain, and where deemed appropriate by a judge of a New Mexico state court of competent jurisdiction, for Lender to obtain one or more of the following: (A) interpretation of this Agreement; (B) to make Borrower perform a specific action Borrower is obligated to perform pursuant to this Agreement, or to make Borrower discontinue some specific action Borrower is precluded from performing pursuant to this Agreement; or (C) to require Borrower to comply with the duties and obligations clearly and expressly agreed to by Borrower within this Agreement.

(xii)    Borrower clearly, expressly, unequivocally, and irrevocably waives its sovereign immunity solely with respect to actions by Lender in accordance with the terms of this Agreement, and Borrower’s limited waiver shall survive the termination or expiration of this Agreement and remain effective until any applicable statute of limitations runs.

(xiii)    Borrower represents and warrants that all of the persons creating and executing this Agreement, and any related agreements necessary to effectuate this Agreement, are actually, fully, properly, apparently, and impliedly authorized to vest all of the persons creating and executing this Agreement with all authorities necessary to bind and obligate Borrower to the terms of this Agreement.

(xiv)    Borrower clearly, expressly, unequivocally, and irrevocably agrees that, to the extent Borrower changes its company, corporate, or organizational form, any resulting company, corporation, or organization will, by Navajo Nation Council resolution, provide all of the same limited waivers of sovereign immunity to Lender as those set forth in this Section 4.10.

(xv)    Borrower agrees that to the extent any provisions of this Agreement are rendered ineffective by any later changes in Navajo Nation Law, any such change shall constitute a breach of the agreement(s) and be actionable under the dispute resolution terms of this Agreement.

(c)    No Waiver of Navajo Nation Sovereign Immunity. The Parties agree that nothing in this Agreement shall be asserted, interpreted, or otherwise understood to constitute any waiver of the Navajo Nation’s sovereign immunity, nor any waiver of any of the Navajo Nation’s rights, powers, or authorities as a sovereign governmental institution, whether express or implied.

(i)    The Parties agree that although Borrower is a wholly-owned instrumentality of the Navajo Nation that otherwise possesses sovereign immunity, by virtue of its relationship to and with the Navajo Nation, Borrower is a company with its own particular assets, liabilities, rights, and obligations.

(ii)    Borrower’s limited waiver of sovereign immunity in this Agreement extends only to Lender, and only as described in this Agreement, and shall not be asserted, interpreted, implied or applied to permit or authorize the sale or transfer of any property held by the Navajo Nation apart from Borrower’s property, whether such Navajo Nation property is held in trust for the Navajo Nation by the United States, or otherwise.

(iii)    Borrower’s limited waiver of sovereign immunity shall not be asserted, interpreted, implied or applied to permit or authorize the sale or transfer of any property held by any Navajo Nation instrumentality, entity or enterprise other than Borrower.

(iv)    Borrower agrees that the Navajo Nation’s independent covenant not to regulate any aspects of the Facilities pursuant to the Facilities Lease remains unchanged and unaffected. Because the Navajo Nation is not a party to this Agreement, this Agreement has no impact upon any existing contractual obligations of the Navajo Nation whatsoever.

5.1    Grant of Security Interest. Borrower hereby grants to Lender a continuing security interest in all presently existing and hereafter arising Collateral to secure prompt repayment of the Obligations and to secure prompt performance by Borrower of each and all of its covenants and obligations under this Agreement and the other Loan Documents; provided that the Collateral shall also secure Borrower’s obligations to Pinnacle West Capital Corporation under the Agreement to Provide Financial Assurance. The security interest granted herein shall at all times be and remain a first priority Lien. Lender’s security interest in the Collateral shall attach to all Collateral without further act on the part of Lender or Borrower.

5.2    No Other Liens. Borrower’s obligations to Pinnacle West Capital Corporation pursuant to the Agreement to Provide Financial Assurance shall not be subordinated, but shall be pari passu with Borrower’s obligations hereunder. As of the Effective Date, the Senior Lender shall have released all liens on the Collateral granted in connection with the Senior Loan Agreement for the benefit of the Senior Lender and the other lenders party thereto. For the avoidance of doubt, with respect to the Collateral, Borrower shall not assign, pledge or otherwise encumber the Collateral except as provided in Section 5.3 hereof. Contemporaneous with execution of this Agreement, Borrower and the other parties thereto will enter into the Intercreditor Agreement.

5.3    Delivery of Agreements. Concurrently with Borrower’s execution of this Agreement, and at any time or times hereafter at the request of Lender, Borrower shall (a) execute and deliver to Lender security agreements, assignments, affidavits, reports, notices, letters of authority and all other documents that Lender may reasonably request, in form satisfactory to Lender, to perfect and maintain perfected Lender’s security interests in the Collateral and in order to fully

consummate all of the transactions contemplated under this Agreement, including the Collateral Assignment and Security Agreement in the form attached hereto as Exhibit B (the “Collateral Assignment”) and related UCC financing statements, and (b) join with Lender in notifying APS of Lender’s security interest in the Collateral obtaining an acknowledgment from APS that it is holding the Collateral for the benefit of Lender. By authenticating or becoming bound by this Agreement, Borrower authorizes the filing of initial financing statement(s), and any amendment(s) covering the Collateral to perfect and maintain perfected Lender’s security interest in the Collateral. Upon the occurrence of an Event of Default, Borrower hereby irrevocably makes, constitutes and appoints Lender (and any of Lender’s officers, employees or agents designated by Lender) as Borrower’s true and lawful attorney-in-fact with power to sign the name of Borrower on any security agreement, mortgage, assignment, certificate of title, affidavit, letter of authority, notice of other similar documents which must be executed and/or filed in order to perfect or continue perfected Lender’s security interest in the Collateral.

5.4    Discharge of Liens. To protect or perfect the security interest which Lender is granted hereunder, Lender may, in its sole discretion, discharge any lien or encumbrance or bond the same, pay any insurance, or obtain any records, and all costs for the same shall be added to the Obligations and shall be payable to Lender on demand.

6.1    Events of Default. It shall constitute an event of default (“Event of Default”) if any one or more of the following shall occur:

(b)    Any representation or warranty made by Borrower in this Agreement or the other Loan Documents, or made or furnished to Lender by or on behalf of Borrower in connection herewith, shall prove to be untrue in any material respect and such default is not cured within fifteen (15) days of Borrower’s receipt of written notice thereof from Lender;

(c)    If any default shall occur in the observance or performance of any of the covenants and agreements contained in the Senior Loan, the Agreement to Provide Financial Assurance, this Agreement or the other Loan Documents, and such default is not cured within thirty (30) days of Borrower’s receipt of written notice thereof from Lender;

(d)    Final judgment or judgments is/are granted against Borrower for the payment of money aggregating in excess of $2,000,000 (net of any insurance proceeds) which remain unpaid for thirty (30) days;

(e)    Borrower shall (i) file a voluntary petition in bankruptcy or file a voluntary petition or an answer or otherwise commence any action or proceeding seeking reorganization, arrangement or readjustment of its debts or for any other relief under the federal Bankruptcy Code,

as amended, or under any other bankruptcy or insolvency Law now or hereafter existing, or consent to, approve of, or acquiesce in, any such petition, action or proceeding; (ii) apply for or acquiesce in the appointment of a receiver, assignee, liquidator, sequestrator, custodian, monitor, trustee or similar officer for it or for all or any part of its property; (iii) make an assignment for the benefit of creditors; or (iv) be unable generally to pay its debts as they become due;

(f)    An involuntary petition or proposal shall be filed or an action or proceeding otherwise commenced seeking reorganization, arrangement, consolidation or readjustment of the debts of Borrower or for any other relief under the federal Bankruptcy Code, as amended, or under any other bankruptcy or insolvency Law, now or hereafter existing and any of the following events occur: (i) Borrower consents to the institution of such action or proceeding; (ii) the petition commencing such action or proceeding is not timely controverted; (iii) the petition commencing such action or proceeding is not dismissed within ninety (90) days of the date of the filing thereof; or (iv) an order for relief shall have been issued or entered;

(h)    Borrower shall file a certificate or articles of dissolution under applicable Law or shall be liquidated, dissolved or wound-up or shall commence or have commenced against it any action or proceeding for dissolution, winding up or liquidation, or shall take any action in furtherance thereof.

6.2    Remedies. If an Event of Default has occurred and is continuing, Lender may, at its option, declare the whole of the Obligations immediately due and payable, without notice or demand, and Lender may, additionally or alternatively, avail itself of any other relief to which Lender may be legally or equitably entitled, under the Collateral Assignment or otherwise, and may exercise the rights of enforcement contained in the Uniform Commercial Code.

7.1    Term and Termination. The term of this Agreement shall end on the Termination Date. Lender may terminate this Agreement without notice upon the occurrence of an Event of Default. Upon the effective date of termination of this Agreement for any reason whatsoever, all Obligations (including all unpaid principal, accrued and unpaid interest due under the Notes) shall become immediately due and payable. Notwithstanding the termination of this Agreement, until all Obligations are paid and performed in full, Borrower shall remain bound by the terms of this Agreement and shall not be relieved of any of its Obligations hereunder, and Lender shall retain all its rights and remedies hereunder and under the other Loan Documents. A termination of this Agreement shall not terminate the Collateral Assignment or any other documents or instruments securing Borrower’s obligations to Pinnacle West Capital Corporation under the Agreement to Provide Financial Assurance.

FOR VALUE RECEIVED, Navajo Transitional Energy Company, LLC, a Navajo Nation limited liability company (“Borrower”), promises to pay to the order of 4C Acquisition, LLC, a Delaware limited liability company (“Lender”), the principal sum of $68,907,000.00, subject to any principal adjustments described below and together with interest at the rate of 3.9% per annum, compounded monthly (the “Base Rate”), on the outstanding principal as provided in this Senior Secured Promissory Note (the “Note”). Capitalized terms used in this Note that are not otherwise defined shall have the meanings set forth in the Credit Agreement between Borrower and Lender, dated concurrently herewith (the “Credit Agreement”).

1.Principal. The principal amount of this Note may be adjusted from time to time as provided in Section 2.1 of the Credit Agreement. Any amounts so added as principal or subtracted from principal shall be noted by Lender on Exhibit A hereto, and such notations shall be conclusive as between Lender and Borrower absent manifest error.

  

2.    Payment.

(b)    All interest charges shall be computed on the basis of a year of 360 days. Principal and interest at the Base Rate shall be due and payable in equal Monthly Installments beginning on July 15, 2018 and continuing on the same day of each month thereafter until this Note is paid in full. Notwithstanding the foregoing, Monthly Installments are subject to deferral as provided in Section 2.2 of the Credit Agreement.

(c)    Notwithstanding any other term, condition or provision hereof to the contrary, the entire unpaid principal balance, all accrued but unpaid interest and all other sums payable hereunder shall be repaid in full on the Stated Maturity Date.

3.    Event of Default. If a Default or an Event of Default has occurred and is continuing within the meaning of and under the Credit Agreement, after notice of such Default and failure to cure within the applicable period stated therein, if any, then the entire principal of this Note, together with accrued interest, shall, at the election of Lender, and without notice of such election, become immediately due and payable, and while any such Default or Event of Default is continuing, the entire unpaid principal balance and accrued interest shall bear interest to the extent permitted by

law at the Default Rate. Interest at the Default Rate shall be payable monthly on the first day of each month until all amounts due under the Note have been paid in full.

4.    Prepayment. Borrower shall have the option to prepay this Note, in full or in part, at any time without premium or penalty upon five (5) days’ advance notice to Lender.

5.    Application of Payments. All payments by Borrower shall be applied first to the payment of late charges and other costs of collection due hereunder, if any, second to the payment of accrued but unpaid interest, and third to the reduction of the then outstanding principal balance.

 

6.    Security. This Note is secured by a first priority lien on the Collateral pursuant to and as provided in the Credit Agreement and the Collateral Assignment and Security Agreement executed and delivered pursuant thereto.

7.    Representations of Borrower. Borrower represents and warrants that the indebtedness evidenced by this Note is required for business or commercial purposes, and that the funds obtained from Lender are not intended to be used, and will not be used, for family, household, agricultural or personal purposes. Borrower further represents that Borrower has full power, authority and legal right to execute and deliver this Note and that the indebtedness evidenced hereby constitutes a valid and binding obligation of Borrower, enforceable in accordance with its terms.

8.    Rights and Remedies of Lender. The rights or remedies of Lender, as provided in this Note, shall be cumulative and concurrent and may, at the sole discretion of Lender, be pursued singly, successively, or together against Borrower. The failure to exercise any such right or remedy shall in no event be construed as a waiver or release of such right or remedy or of the right to exercise such right or remedy at any later time.

9.    Waiver by Borrower. Borrower and all endorsers, guarantors, sureties, accommodation parties hereof, and all other persons who are or may become liable for repayment of the indebtedness evidenced by this Note, jointly and severally (a) waive all applicable exemption rights, whether under the state constitution, homestead laws or otherwise, (b) waive diligence, presentment, protest and demand, and also notice of protest, of demand, of nonpayment, of dishonor and of maturity, (c) waive recourse to suretyship defenses generally, (d) consent to any and all renewals, extensions or modifications of the terms hereof (including time of payment), and (e) agree that any renewal, extension or modification of the terms hereof, or any other indulgences, shall not affect the liability of any of such parties for repayment of the indebtedness evidenced by this Note. Any renewals, extensions or modifications of the terms hereof may be made without notice to any of the parties referred to above.

10.    Amendment; No Waiver by Lender. This Note may not be amended, modified or changed, nor shall any waiver of any provision hereof be effective, except only by an instrument in writing signed by the party against whom enforcement of such amendment, modification, change or waiver is sought; provided, however, that this Section 10 shall in no way be a limitation on the consents and waivers set forth in Section 9. Failure of Lender to exercise any right hereunder or under the Credit Agreement or Collateral Assignment shall not constitute a waiver of the right to

exercise the same in the event of any subsequent default, or in the event of continuance of any existing default after demand for strict performance hereof.

11.    Payment of Collection Costs. Borrower and all endorsers, guarantors, sureties, accommodation parties hereof, and all other persons who are or may become liable for repayment of the indebtedness evidenced by this Note, agree, jointly and severally, to pay all costs of collection, including reasonable attorneys’ fees and all costs of suit, in the event the unpaid principal amount of this Note, or any payment of interest or principal and interest thereon, is not paid when due. Such parties shall pay all such costs whether suit is brought or not, and whether any such suits or proceedings are maintained in courts of original jurisdiction or courts of appellate jurisdiction, or in a bankruptcy court or through other legal proceedings. In any suit, the amount of reasonable attorneys’ fees shall be determined by the judge of the court and not the jury.

12.    Compliance with Usury Laws. Borrower hereby agrees to pay an effective rate of interest that is the sum of the interest rate provided for herein, together with any additional rate of interest resulting from any other charges of interest or in the nature of interest paid or to be paid in connection with the credit evidenced by this Note. Notwithstanding anything to the contrary contained in this Note or the Credit Agreement, the total liability for payments in the nature of interest shall not exceed the limits imposed by the usury laws of the State of New Mexico. If Lender receives as interest an amount which would exceed such limits, such amount which would be excessive interest shall be applied to the reduction of the unpaid principal balance and not to the payment of interest; and if a surplus remains after full payment of principal and lawful interest, such surplus shall be remitted to Borrower by Lender, and Borrower hereby agrees to accept such remittance. If this Section 12 becomes operative, the entire principal balance and accrued interest outstanding hereunder shall at the option of Lender become immediately due and payable and shall bear interest at the maximum rate then permitted by the usury laws of the State of New Mexico until all the then outstanding obligations of this Note, as modified by this Section 12, are paid and performed in full. The acceleration provided in this Section 12 may be avoided by Borrower and all parties liable to Lender by then waiving any and all usury claims and defenses they then have.

13.    Assignment. Borrower shall not assign this Note without Lender’s prior written consent which may be granted or withheld in Lender’s sole and absolute discretion.

14.    Governing Law. This Note shall be governed by, and construed and enforced in accordance with, the laws of the State of New Mexico, without regard to the application of conflicts of law principles.

15.    Credit Agreement. This Note evidences indebtedness incurred under the Credit Agreement, the terms and conditions of which, including all waivers of sovereign immunity, are incorporated herein by reference.

IN WITNESS WHEREOF, Borrower has executed this Note as of the date first written above.

Navajo Transitional Energy Company, LLC, a Navajo Nation limited liability company

By:                     _____

Name: Clark Moseley

Title: Chief Executive Officer

This Collateral Assignment and Security Agreement (this “Assignment”) is dated as of June 29, 2018, but made effective as of July 3, 2018 by and between Navajo Transitional Energy Company, LLC, a Navajo Nation limited liability company (“Assignor”), 4C Acquisition, LLC, a Delaware limited liability company (“Lender”), and Pinnacle West Capital Corporation, an Arizona corporation (“PNW” and, together with Lender, the “Assignees”).

A.Assignor and Lender are parties to that certain Purchase and Sale Agreement, dated as of June 29, 2018 (the “PSA”), pursuant to which, among other things, Assignor is acquiring from Lender certain Assets.

B.Lender agreed in the PSA to finance the Purchase Price payable by Assignor for the Assets. Concurrently with the execution of this Assignment, Assignor and Lender are entering into a Credit Agreement and Note. This Assignment is the Collateral Assignment referred to in the PSA given to secure payment of the Note.

C.In the PSA, it is a condition to Closing that Assignor be in compliance as of the Closing Date with the Four Corners Financial Assurance Policy. PNW has agreed to provide the financial assurances on behalf of Assignor required under the Four Corners Financial Assurance Policy pursuant to that certain Agreement to Provide Financial Assurances, dated as of June 29, 2018, but made effective July 3, 2018 (the “Financial Assurances Agreement”), between PNW, Lender and Assignor. This Assignment is the Collateral Assignment referred to in the Financial Assurances Agreement given to secure the repayment obligations of Assignor thereunder.

D.In order to induce Lender to enter into the PSA and the Credit Agreement, and in order to induce PNW to enter into the Financial Assurances Agreement, Assignor has agreed to secure its obligations to Lender and PNW as provided in this Assignment.

NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements contained in this Assignment, Assignor and Assignees, intending to be legally bound, hereby agree as follows:

1.Definitions. Capitalized terms used in this Assignment have the meanings set forth in Section 24.

2.Security Interest. As security for the full and prompt payment and performance by Assignor of (a) all present and future Obligations to Lender under the Credit Agreement to, among other things, pay the principal amount of and interest under the Note, and (b) all present and future obligations of Assignor under the Financial Assurances Agreement to repay PNW for, among other things, amounts paid or advanced by PNW in order for Assignor to satisfy its obligations under the

Four Corners Financial Assurance Policy (the obligations described in clauses (a) and (b) collectively, the “Secured Obligations”), Assignor hereby absolutely, unconditionally and irrevocably assigns, transfers, grants a security interest in and sets over to Assignees an aggregate of twenty-five percent (25%) of all present and future coal accounts receivable and any proceeds thereof due to Assignor from APS under the CSA, provided that once any amounts have been paid to Assignor by APS such paid amounts shall no longer be included as collateral of the Assignees (the collateral of the Assignees being hereafter referred to as the “25% Coal Accounts Receivable Interest”) until such time as all Secured Obligations are satisfied in full. The Lien granted by this Assignment is a first priority Lien on the 25% Coal Accounts Receivable Interest.

3.Remedies upon Default. If Assignor is in Default of any of the Secured Obligations in accordance with the terms thereof, Lender or PNW, as the case may be, shall have the right to direct APS in writing to pay the 25% Coal Accounts Receivable Interest directly to Lender or PNW, as the case may be, until such time as the Default has been cured or until the Secured Obligations are satisfied in full. If there is a Default with respect to Secured Obligations owed to both Lender and PNW, then they shall issue a joint written direction to APS, and the 25% Coal Accounts Receivable Interest shall be paid by APS to Assignees in the proportion set forth in the joint written direction. APS shall be entitled to rely on any direction issued by Lender pursuant to this Section 3 without liability to Assignor, and Assignor hereby irrevocably authorizes APS to rely upon and comply with any written direction or demand by Lender or PNW for payment of the 25% Coal Accounts Receivable Interest to either or both of them. Assignees shall not be required to prove or otherwise establish for the benefit of APS the existence of a Default giving rise to rights under this Assignment, and APS is hereby authorized to rely upon the written statement of Lender and/or PNW with respect to the existence of such a Default. Without in any way limiting the effectiveness of the aforesaid authorization, if, during the existence of a Default giving rise to rights under this Assignment, Assignor shall receive all or any portion of the 25% Coal Accounts Receivable Interest that is receivable by Lender and/or PNW under this Assignment, Assignor will hold the same in trust and will remit the same immediately to Lender and/or PNW, as applicable. So long as any such Default is continuing, Assignees shall have, in addition, all of the rights of a secured creditor after Default respecting the 25% Coal Accounts Receivable Interest.

4.No Obligation. Assignees shall have no responsibility to enforce collection of the 25% Coal Accounts Receivable Interest and shall have no other responsibility in connection therewith, except the responsibility to account for funds actually received. Except as provided by Law, neither this Assignment nor any action or inaction on the part of Assignees shall constitute an assumption on the part of either Lender or PNW of any duty or obligation with respect to APS or the 25% Coal Accounts Receivable Interest, nor shall Assignees have any duty or obligation to make any payment to be made by Assignor, or to present or file any claim, or to take any other action to collect or enforce the payment of any amounts or the performance of any obligations that have been assigned to Assignees or to which Assignees may be entitled hereunder at any time or times. No action or inaction on the part of Lender or PNW shall adversely affect or limit in any way the rights of either Lender or PNW hereunder, except for Lender’s or PNW’s gross negligence or willful misconduct. For the avoidance of doubt, the rights of Lender hereunder shall not be impacted in any way by any gross negligence or willful misconduct on the part of PNW, and the

rights of PNW hereunder shall not be impacted in any way by any gross negligence or willful misconduct on the part of Lender.

5.Indemnification. Assignor shall indemnify and hold Lender, PNW and APS harmless from and against any and all harm, liabilities, losses, damages, costs, and expenses that either Lender, PNW or APS may incur by reason of this Assignment, except to the extent such harm, liability, loss, damage, cost or expense is the result of the gross negligence or willful misconduct of Lender, PNW or APS, respectively. The amount thereof, including reasonable attorneys’ fees, together with interest on such amount from the date such amount or amounts were incurred by such Lender, PNW or APS to the date of payment thereof to Lender, PNW or APS by Assignor, shall be secured hereby, and Assignor shall reimburse Lender, PNW and APS therefor immediately upon demand.

6.Representations and Warranties of Assignor. Assignor represents and warrants to Assignees that (a) it has full right, power and authority to assign the 25% Coal Accounts Receivable Interest pursuant to the CSA, (b) the 25% Coal Accounts Receivable Interest is free and clear of all Liens, and has not been assigned, pledged or encumbered by Assignor, except pursuant to this Assignment, (c) Assignor is not in default under the CSA, and this Assignment complies with and does not cause Assignor to be so in default, (d) Assignor will receive value as a result of the Credit Agreement, Note, Financial Assurances Agreement and CSA sufficient to provide legal consideration to support the validity of this Assignment; and (e) this Assignment is the valid and binding obligation of Assignor, enforceable against Assignor in accordance with its terms. Without limiting the generality of the foregoing, Assignor represents that the Senior Lender has been provided with this Assignment, has consented hereto and has agreed that the Lien described herein shall be a first Lien on the 25% Coal Accounts Receivable Interest, free and clear of any Liens of the Senior Lender. The foregoing representations and warranties shall survive the execution and delivery of this Assignment.

7.Further Assurances. Assignor, at its expense, shall execute and deliver all such instruments and take all such action as Lender and/or PNW from time to time may reasonably request in order to obtain the full benefits of this Assignment and of the rights and powers herein created.

8.Termination. The Assignment shall terminate only upon payment in full of each of the Secured Obligations in accordance with the terms and conditions thereof. Assignees, at Assignor’s sole cost and expense, will execute and deliver such instruments as Assignor may reasonably request to evidence such termination.

9.Binding Nature. The provisions of this Assignment shall be binding upon Assignor, its successors and assigns, and all Persons claiming under or through Assignor or any such Person, and shall inure to the benefit of and be enforceable by Lender, PNW, APS and their respective successors and assigns.

10.Perfection of Security Interest. This Assignment shall constitute a security agreement for all purposes under the Uniform Commercial Code and shall be construed in accordance with and governed by the Laws of the State of Arizona. Concurrently with execution and delivery of this Assignment, Assignor shall file a UCC financing statement with the Arizona Corporation

Commission, the New Mexico Secretary of State and the Navajo Nation Commerce Department within the Division of Economic Development evidencing the first priority Lien granted herein. Assignor will from time to time execute and file or record, at its own cost and expense, all additional financing statements, amendments or supplements thereto, continuation statements with respect thereto and all other instruments that may be necessary or that Lender or PNW may from time to time reasonably request, in order to perfect, protect and maintain the security interest hereby granted and its priority. Assignor will promptly deliver to Lender and PNW a copy of each such instrument and evidence of its filing or recording in the manner required. Assignor further agrees that a carbon, photographic, photostatic or other reproduction of this Assignment or of a financing statement is sufficient as a financing statement. Assignor hereby irrevocably appoints each of Lender and PNW as its attorney-in-fact, coupled with an interest, to file with the appropriate public office on its behalf, if necessary, any financing statements or other statements signed only by Lender or PNW, as secured party, in connection with the security interest hereby granted.

11.Amendment and Waiver. No waiver and no modification or amendment of any provision of this Assignment is effective unless made in writing and duly signed, in the case of an amendment, by each Party to this Assignment, or in the case of a waiver, by the Party against whom the waiver is to be effective, referring specifically to this Assignment, and then only to the specific purpose, extent and interest so provided. No failure or delay by Lender or PNW in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude or estop any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided to Lender and PNW shall be cumulative and not exclusive of any rights or remedies provided by Law.

12.Counterparts. This Assignment may be executed in one or more counterparts, each of which is an original, but all of which together constitute one and the same instrument. This Assignment shall become effective when each Party hereto shall have received a counterpart hereof signed by the other Parties hereto.

13.Severability. If any provision hereof is held invalid or unenforceable by any court or as a result of future legislative action, this holding or action will be strictly construed and will not affect the validity or effect of any other provision hereof, so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such a determination, the parties shall negotiate in good faith to modify this Assignment so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible. To the extent permitted by Law, the Parties waive, to the maximum extent permissible, any provision of Law that renders any provision hereof prohibited or unenforceable in any respect.

14.Assignability. This Assignment is not assignable by Assignor without the prior written consent of Assignees, which may be provided or denied in the sole discretion of Lender and PNW, and no assignment shall relieve Assignor of any of its obligations hereunder. This Assignment is binding upon and inures to the benefit of the successors and permitted assigns of the Parties.
