Owner hereby agrees to pay for, and Contractor hereby agrees to perform, Work in accordance with Section 4.2 and Section 4.3.

2.3 [Reserved.]

2.4 [Reserved.]

2.5 [Reserved.]

2.6 [Reserved.]

Section 3. Delivery of Lignite; Task Order Services

3.1 Delivery of Lignite

To the extent such delivery of lignite does not interfere with Contractor’s ability to perform the Post-Mining Reclamation, Owner hereby agrees to accept from Contractor and pay for, and Contractor hereby agrees to use commercially reasonable efforts to deliver to Owner, in accordance with the terms of this Agreement, lignite from the stockpile of the Mine utilizing the equipment at the rates set forth on Exhibit B. Owner shall notify Contractor in writing of the number of Tons of lignite that Owner shall require prior to any such delivery.

3.2 Task Order Services

In addition to receiving any lignite in accordance with Section 3.1, Owner hereby agrees to pay Contractor for any services other than the Work at the rates set forth on Exhibit B. The scope of any such services (“Task Order Services”) shall be agreed by the Parties on a task order in the form of Exhibit C. To the extent Owner requests that Contractor oversee the disassembly

and/or packing of the dragline, this work shall be completed pursuant to a task order, which shall include a profit element not to exceed [*] percent of the cost related to disassembly and/or packing of the dragline.

Section 4.The Work

4.1 Components of the Work

The Work performed pursuant to this Agreement shall consist of the Mine permit revision process and the Post-Mining Reclamation, which includes, but is not limited to, spoil leveling, pit and ramp backfill, final grading, clearing and grubbing, oxidized material removal and replacement, mine road reclamation, pond backfill and removal, the dragline walkway construction and the relocation of the dragline from the active pit to the facilities site, facilities disassembly and removal/disposal only to the extent retention of such facilities is not permitted in the Permit Revisions, revegetation, revegetation maintenance, water management/monitoring, site security, and all related and ancillary work associated with the foregoing (except to the extent such work is no longer necessary due to an Approved Permit Revision), as well as any Task Order Services.

4.2 Permit Revisions

(a)Contractor shall perform Mine permit revision work and Mine reclamation work allowed under the current permit. Contractor shall use commercially reasonable efforts to complete at least seventy-five percent (75%) of the dirt Work to be performed by the dragline and bulldozers permitted to be performed under the current Mine permit within twenty-one (21) Months of the Effective Date. At a time determined by Contractor after non-binding consultation with Owner, Contractor shall submit an application to the Railroad Commission of Texas (the “RRC”) requesting the below Mine permit revisions (the “Permit Revisions”), which the Parties anticipate will occur not more than 120 days after Effective Date. The Parties agree that the cost savings associated with each Permit Revision (“Cost Savings”), for purposes of allocating Cost Savings to Owner, is as set forth below, except as noted in Section 4.2(b). To the extent the RRC finally approves a Permit Revision and any applicable appeal period has lapsed without an appeal (such approved Permit Revision, the “Approved Permit Revision”), Owner shall receive [*] of the Cost Savings associated with that Permit Revision (the “Owner Cost Savings”); provided that the Owner Cost Savings shall not exceed $2,200,000 in the aggregate. Owner shall, at its cost, use commercially reasonable efforts to promptly take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to assist Contractor in preparing and submitting the Mine permit revision application and in obtaining RRC approval with respect to the Permit Revisions; provided that this shall not obligate Owner to engage or hire any third-party attorneys, accountants, experts, or consultants. To the extent that the RRC has not approved the Permit Revisions within [*] after the Effective Date, Contractor shall have an additional sixty (60) day period to pursue such revisions while also, if desired,

seeking Owner’s consent to continue efforts to secure such revisions. To the extent the RRC does not approve the Permit Revisions within this time period or the longer period, if any, agreed to in writing by Owner, the Permit Revision application shall be revised to remove the Permit Revision causing such delay or, to the extent the Permit Revision application cannot be severed, the Permit Revision application shall be withdrawn.

(b)To the extent the RRC partially approves any Permit Revision ([*]), Contractor shall re-calculate the applicable Cost Savings in an objective manner mutually acceptable to Contractor and Owner.

(c)Upon Owner’s request, not to exceed an administratively reasonable number of times per year, Contractor shall file with the RRC in the appropriate manner and form necessary to effectuate such request (along with any required supporting documentation) for a reduction in the Owner’s reclamation bond obligation under the Mine Permit (the “Reclamation Bond Reduction Work”). Contractor in performing the Reclamation Bond Reduction Work will submit to the RRC the [*] bond calculation to Owner allowed under current laws and regulations and shall consult with Owner prior to any submittal to the RRC regarding the calculation and the potential bond reduction.

4.3 Post-Mining Reclamation Work

Contractor shall perform all Work necessary to complete the Post-Mining Reclamation in accordance with the Mine permit as amended by the Approved Permit Revisions.

Section 5.[Reserved.]

Section 6.Mine Financial Arrangements

6.1 Certain Owner Responsibilities

Owner shall provide to Contractor, free of any rent or other usage payment but exclusive of operation and maintenance costs other than as provided in Section 7.2(a), all permits, bonds, the insurance required under Section 8.5, the equipment currently located at the Mine that is identified on Exhibit D (“Owner Equipment”), existing Infrastructure and electric power (until Owner’s termination of the existing Panola ▇▇▇▇▇▇▇▇ electrical service agreement, which Owner anticipates will be [*] months after the Effective Date) required for the Work to be completed pursuant to this Agreement in accordance with the terms hereof; provided that Owner shall have

no obligation to maintain the existing Infrastructure except to the extent that such Infrastructure is damaged by an event of Force Majeure and Contractor requires such Infrastructure to be repaired to its pre-Force Majeure condition or a lesser condition specified by Contractor to enable Contractor to perform the Work, in which case Owner shall pay the cost of such repair. To the extent any piece of Owner Equipment is no longer available to perform the Work, the Parties shall meet and discuss in good faith whether (i) Owner shall provide a replacement piece of equipment reasonably acceptable to Contractor, which shall be of a similar type and in substantially the same condition as the underlying Owner Equipment or (ii) Contractor shall rent or otherwise acquire such replacement piece of equipment.

Owner shall reimburse Contractor for all of the Direct Costs set forth in Section 7.2(e). For the avoidance of doubt Contractor shall have no obligation to provide any payment to Owner of any other funding or security, or incur or guaranty any indebtedness, lease or similar obligation, related to Owner’s obligations under this Section 6.

6.2 Certain Contractor Responsibilities

Except as otherwise provided herein, Contractor shall, for the Compensation set forth herein but otherwise at its expense, provide all Contractor Equipment, supplies and personnel (including any contractors, subcontractors, consultants, attorneys, or agents subject to Section 7.2(e)) necessary to perform the Work as well as the insurance required under Section 8.

6.3 Working Capital

Contractor shall provide all working capital required for Contractor to perform all Work pursuant to this Agreement.

6.4 Electric Power

Contractor shall bear all electricity costs, including demand charges and energy charges, associated with the operation of the dragline at the Mine and metered facilities at the Mine. Upon Contractor’s suspension of its dragline operations at the Mine, Owner shall pay all electricity costs, including demand charges and energy charges, associated with the Mine, including all unpaid demand charges and other amounts owed due to early termination of Owner’s contract with Panola-▇▇▇▇▇▇▇▇ Electric Cooperative, Inc. which shall include, but not be limited to, upon the suspension of the dragline operations, the “Minimum Monthly ▇▇▇▇” set forth in paragraph No. 5(c) and Appendix B of that certain Electric Service Agreement, dated as of October 31, 2014, by and between Panola-▇▇▇▇▇▇▇▇ Electric Cooperative, Inc. and Owner; provided that Contractor shall bear any costs to remove the mine substation and the dragline powerline attached to the [*] substation; provided further that Contractor shall provide a credit to Owner in each Monthly invoice to cover a proportionate usage/energy charge of electricity consumed by the operation of any pumps by Contractor at the Mine. Such usage will be determined by Contractor’s usage meters. For the avoidance of doubt, Owner’s obligation to pay all electricity costs shall expire upon the effective termination of Owner’s contract with the Panola-▇▇▇▇▇▇▇▇ Electric Cooperative and Owner’s payment of all amounts owed thereunder.

6.5 Owner’s Failure To Provide Mine Financial Arrangements

If Owner fails to provide any of the Owner Equipment at the Mine or Infrastructure contemplated by this Section 6 or if Owner fails to perform Owner’s other obligations hereunder and as a consequence, Contractor is unable to perform the Work as required by this Agreement, Contractor shall be deemed to have fulfilled its obligations under this Agreement if it produces the Work that Contractor can reasonably produce from time to time and no Contractor Default under Section 15.1.1(a) shall be deemed to occur to the extent caused by such Owner’s failure.

6.6 Inventory

Owner shall provide the supplies inventory acquired pursuant to the Acquisition for the Work to be performed hereunder; provided that Owner shall have no obligation to supplement such inventory acquired pursuant to the Acquisition over the term of the Agreement. Except as set forth below, Contractor shall use such inventory as needed for the Work and Contractor shall provide a credit to Owner in the applicable Monthly invoice for Contractor’s proportionate usage of any such inventory part based on the value as reflected in Exhibit E of this Agreement; provided that Contractor shall have the discretion to use its own inventory to Contractor or inventory provided by third-parties to the extent such inventory is, in Contractor’s opinion, likely to have a lower all-in cost to Contractor; provided further that Contractor shall provide advanced notice to Owner of Contractor’s intention to obtain any inventory set forth on Exhibit E from a third-party in order to provide Owner with the opportunity to provide such inventory at a price equal to, or less than, such third-party’s offer.

Section 7.Compensation

7.1 Compensation Prior to the Effective Date

Contractor agrees that Cabot is the primary payor of Compensation payable to Contractor for performance under the Amended and Restated LMA prior to the Effective Date, including the Demobilization Costs set out in Section 7.2(e)(vi).

7.2 Compensation to Contractor

Owner shall pay all costs associated with the items it is obligated to provide under Section 6.1. Commencing on the Effective Date, Owner shall pay Contractor in accordance with Section 11 an amount that equals the sum of (a) the Mobilization Fee (Section 7.2(a)), (b) the Progress Payments (Section 7.2(b)), (c) the Quarterly Fees (Section 7.2(c)), (d) the Per Diem Payments (Section 7.2(d)), (e) the Direct Costs (Section 7.2(e)) and the rates associated with any Task Order Services (Section 3.2). All amounts payable by Owner during the term of the Agreement under this Section 7.2 shall constitute the “Compensation.” Compensation paid to Contractor during the term of the Agreement shall not be adjusted to account for inflation or deflation of any kind. For the avoidance of doubt, if the Work continues, for any reason, past the last Quarterly Fee payment, the only Compensation payable to Contractor will be Direct Costs and, if applicable, any remaining Progress Payments. For the further avoidance of doubt, while the initial amount of Compensation under Section 7.2(a), Section 7.2(b), and Section 7.2(c) equals the Fixed Fee, the Parties agree and acknowledge that other provisions in this Agreement may change the ultimate amount of Compensation due and payable to Contractor, including, but

not limited to, Per Diem Payments, Direct Costs, Task Order Services, and Approved Permit Revisions.

(a)Mobilization Fee

Owner shall pay to Contractor a mobilization fee (the “Mobilization Fee”) in an aggregate amount of [*] to be payable in four quarterly installments of [*]; provided that if the Permit Revisions are not classified or processed by the RRC as a significant revision to the Mine permit, then the Mobilization Fee shall be reduced by [*] which reduction shall be pro-rated on the remaining quarterly installments (or in the event all quarterly installments of the Mobilization Fee have been paid as a [*] credit on Owner’s next [*] invoices). Owner shall pay the first $[*] installment of the Mobilization Fee within seven (7) days of the Effective Date and the remaining three (3) installments of the Mobilization Fee shall be included in the Monthly invoice of the first month of the next three successive calendar quarters after the Effective Date.

(b)Progress Payments

(i)During the term of the Agreement, Owner shall pay to Contractor progress payments (each such payment, a “Progress Payment”) in an aggregate amount up to [*] (such total amount, the “Total Progress Payment”); provided that at the time of any Approved Permit Revision the Total Progress Payment shall be reduced by the Owner Cost Savings for any applicable Approved Permit Revision, provided that the aggregate amount of reductions to the Total Progress Payment shall not exceed $2,200,000.

(ii)Within five (5) Business Days of the Effective Date, Contractor shall conduct an initial drone survey of the Mine (the “Baseline Survey”). Owner shall have the right to have a representative present to observe the Baseline Survey.

Within thirty (30) days after the Baseline Survey is completed, Contractor shall deliver to Owner the final Mine reclamation design topography map (the “Final Topo”). The Final Topo shall be compared to the Baseline Survey to determine, in accordance with good mine engineering practice, the total cubic yards of material to be moved (the “Aggregate Cubic Yards”) in connection with the Work. For the avoidance of doubt, the Aggregate Cubic Yards shall exclude any materials that are moved that do not reduce the Aggregate Cubic Yards.

On the last working day of each month (or, in the sole discretion of Contractor, towards the last working day of each month in the event of inclement weather), Contractor shall perform a drone survey (the “Monthly Survey”), which Owner shall have the right to observe. Contractor shall compare each Monthly Survey to the prior Month’s Monthly Survey, the Baseline Survey, and Final Topo to determine the percentage completion of work during each Month, which shall be measured in cubic yards.

(iii)With respect to each Month, Owner shall pay the earned percentage of the Total Progress Payment in accordance with the following formula:

Monthly Progress Payment = (A/B) multiplied by the Total Progress Payment ([*])

Where:

A = the total cubic yards handled that reduce the Aggregate Cubic Yards remaining in the particular Month, and

B = the Aggregate Cubic Yards.

In respect of any Month in which Contractor implements a change in Work plan (not included in the Permit Revisions) that reduces the Aggregate Cubic Yards, the total amount of cubic yards eliminated to achieve Final Topo will be removed from the denominator “B” above, resulting in an increased Monthly payment to Contractor for such Month; provided that if such change in Work plan is not approved by the RRC, at the time when the RRC would customarily approve such a change in the Work plan, and Post-Mining Reclamation Work is delayed more than 60 days due to Work necessary to correct such change in Work plan (or any order, recommendation, or advice opinion or letter by the RRC to suspend or cease work until such change is corrected), Contractor will be responsible for Owner’s actual out-of-pocket expenses due to such delay including, but not limited to, reclamation bond premiums and costs (such as capital reserve costs) as well other land holding costs in an aggregate amount not to exceed [*].

Contractor shall provide to Owner copies of the Baseline Survey, the Final Topo and each Monthly Survey, as well as any Work plan that is relied upon pursuant to the paragraph above.

To the extent an Approved Permit Revision is obtained, Contractor shall adjust the Aggregate Cubic Yards based on comparing the recent Monthly Survey to the Final Topo, incorporating the updated Aggregate Cubic Yards as the denominator “B” above for such Progress Payment calculations. To the extent an Approved Permit Revision is obtained, Contractor shall adjust the Aggregate Cubic Yards based on comparing the recent Monthly Survey to the Final Topo, incorporating the updated Aggregate Cubic Yards (the “Adjusted Aggregate Cubic Yards”) as the denominator “B” above for such Progress Payment calculations. Further, Contractor shall adjust the Total Progress Payment to reflect the remaining balance after deducting all prior Monthly Progress Payments and Owner Cost Savings (the “Adjusted Total Progress Payment”). With respect to each Month after the Approved Permit Revisions are obtained, Owner shall pay the earned percentage of the Adjusted Total Progress Payment in accordance with the following formula:

Monthly Progress Payment = (A/B) multiplied by the Adjusted Total Progress Payment ([*] subtracted by all prior Monthly Progress Payments and Owner Cost Savings)

Where:

A = the total cubic yards handled that reduce the Adjusted Aggregate Cubic Yards remaining in the particular Month, and

B = the Adjusted Aggregate Cubic Yards.

The receiving Party shall have the right to use or disclose to third parties such proprietary and/or confidential data only, in its sole best judgment, for the purposes of licensing, construction, operation or maintenance as is required by Applicable Laws and does not have the right to publish or otherwise disclose it to third parties for any reason without written approval of the disclosing Party. If a dispute arises between the Parties with respect to any work, either Party may disclose the other’s proprietary and/or confidential data on a confidential basis to any expert provided that such expert sign a statement agreeing not to further disclose such proprietary and/or confidential data.

22.1.3 Notwithstanding anything in this Section 22.1 to the contrary, either Party shall have the right to disclose such proprietary and/or confidential data to any governmental authorities when required by same but shall exert reasonable effort to secure confidential treatment of such data to be so disclosed.

22.2 Public Disclosures

Neither Party shall publish or release any photographs, make any announcement or release any information relating to the other Party or any of its Affiliates, this Agreement or any discussions between the Parties to any member of the public or press unless prior written consent is obtained from the other Party, which consent shall not be unreasonably withheld; provided, however, that either Party may disclose this Agreement and its related documents (a) to its employees, directors, shareholders, members, Affiliates, accountants, attorneys, auditors, insurers, potential investors and potential lenders, and/or (b) to any governmental authority having jurisdiction over such Party to the extent necessary for such Party to comply with its obligations to the governmental authority in which event such Party shall notify the other Party as far in advance as reasonably possible of the anticipated disclosure to such governmental authority; provided, further, however, that a Party that has, or has an Affiliate that has, securities that are publicly traded may issue a press release or make a public disclosure without the consent of the other Party to the extent that the release or disclosure is required by applicable securities laws.

Section 23.Waivers, Remedies and Amendments

23.1 Exclusive Remedies; Limitations on Damages

23.1.1 The remedies provided for in this Agreement are the exclusive remedies of the Parties for violation of the terms and conditions of this Agreement. No Party shall seek, and each Party hereby waives the right to seek, and agrees to prevent its Affiliates from seeking, any other remedies, whether available at law, in equity or otherwise, except where expressly provided for by the terms of this Agreement. Except as set forth in this Section 23.1.1 and Section 23.1.2, each Party hereby agrees that only the actual damages suffered by a Party shall be sought and may be recovered, and that none of the following types of damages shall be sought or recovered: consequential, indirect, exemplary and punitive damages, lost profits or revenues, and all similar types of damages and remedies.

23.1.2 If this Agreement prematurely terminates prior to the completion of the Work for any reason other than a Contractor Default, Owner, in addition to the amounts payable under Section 15.5, shall pay promptly to Contractor the Agreed Damages. “Agreed Damages” shall

mean if this Agreement terminates (i) on or prior to December 31, 2021, [*] of the remaining Progress Payments outstanding and [*] of all then-remaining Quarterly Fees not yet paid under the Agreement, (ii) on or prior to December 31, 2022, [*] of the remaining Progress Payments outstanding and [*] of all then-remaining Quarterly Fees not yet paid under the Agreement and (iii) on January 1, 2023 or thereafter, [*] of the remaining Progress Payments and [*] of all then remaining Quarterly Fees not yet paid under the Agreement. Owner agrees that the Agreed Damages are a reasonable measure of the damages suffered by Contractor in the event this Agreement terminates prior to the end of the primary term of this Agreement. As such, the Agreed Damages constitute reasonable liquidated damages and not a penalty.

23.2 Amendments

Any modification or amendment of the terms and provisions of this Agreement shall be valid and effective only if and when made in writing and duly executed by the Parties.

Section 24.Governing Law

This Agreement shall be governed by, and construed and interpreted in accordance with the laws of the State of Texas without regard to its conflicts of laws principles.

Section 25.Relationship of the Parties

25.1 Owner and Contractor agree that Contractor, in performing its obligations hereunder, shall be an independent contractor, and not the agent, servant or employee of Owner. Nothing contained in this Agreement shall be construed to constitute or create a joint venture, trust, mining partnership, commercial partnership, fiduciary relationship or other relationship between Owner and Contractor whereby either Party would be liable for the acts and deeds of the other Party hereto, except as specifically set forth herein.

25.2 Contractor shall be responsible for all acts and omissions of subcontractors, its and their suppliers and of personnel employed in the performance of Contractor’s obligations under this Agreement and shall be specifically responsible for sufficient and competent supervision and inspection to assure compliance in every respect with the requirements of this Agreement.

25.3 There shall be no contractual relationship between any subcontractor or supplier and Owner arising out of or by virtue of this Agreement.

25.4 No provision of this Agreement is intended to be, or is to be construed to be, for the benefit of any third party.

25.5 (a) Contractor shall indemnify, hold harmless and defend Owner, its successors and assigns and Affiliates of Owner, from and against any demand, claim, action or cause of action, liability, damage and loss including, without limitation, interest, penalties and attorney’s fees and expenses, asserted against, relating to, imposed upon or incurred by Owner or its Affiliates by reason of or resulting from claims by any third party for (i) bodily injury (including death), (ii) property damage (including, but not limited to, loss of use thereof), or (iii) damage to the environment, in each case, caused by or resulting from Contractor’s breach of this Agreement, the willful misconduct of Contractor or any of its subcontractors, or the failure

of Contractor or any of its subcontractors to perform in a manner consistent with commercially reasonable surface lignite mining practices or mine reclamation practices. For the purposes of clause of the preceding sentence, “third party” shall include employees of Owner and Owner’s Affiliates.

(b) Owner agrees, however, that Contractor shall not be obligated to so indemnify, hold harmless or defend Owner or its respective successors and assigns to the extent (1) any loss or liability with respect to which Contractor is not covered by insurance, unless the absence of insurance results from the failure of Contractor to provide the insurance that Owner required Contractor to provide in accordance with the terms of this Agreement, or (2) any loss or liability in excess of the amount which is covered by insurance, including the amount of any deductible, unless such deductible is higher or the insurance limits are lower than the deductible or limits that Owner required Contractor to maintain in accordance with this Agreement. Notwithstanding anything to the contrary in Section 25.5(a) or Section 25.5(b), to the extent Contractor breaches this Agreement, Contractor shall indemnify, hold harmless or defend Owner or its respective successors and assigns for losses and liabilities out-of-pocket in an aggregate amount not to exceed [*] in addition to any amounts covered by insurance pursuant to the preceding sentence.

25.6 (a) Owner shall indemnify, hold harmless and defend Contractor, its successors and assigns and Affiliates of Contractor, from and against any demand, claim, action or cause of action, liability, damage and loss including, without limitation, interest, penalties and attorney’s fees and expenses, asserted against, relating to, imposed upon or incurred by Contractor or its Affiliates by reason of or resulting from claims by any third party for (i) bodily injury (including death), (ii) property damage (including, but not limited to, loss of use thereof), or (iii) damage to the environment, in each case, caused by or resulting from Owner’s breach of this Agreement, or the willful misconduct of Owner or its subcontractors. As used in the preceding sentence, “third party” shall include employees of Contractor and Contractor’s Affiliates.

(b) Any disputes arising under this Section 25.6 shall not be subject to Section 17 of this Agreement.

25.7 Notwithstanding anything in this Agreement, to the contrary, the Parties agree that the indemnity provisions set forth in Section 25.5 and 25.6 above are not intended to, nor shall they be construed to operate as, a limitation of any insurance coverages acquired by either Owner or by Contractor which cover and affect the operation of the Mine by Contractor.

Section 26.Limitations of Contractor’s Functions

During the term of this Agreement, Contractor shall have the right to cooperate with and permit its personnel to perform any work or services for Affiliates of Contractor, provided such activities do not interfere with Contractor’s ability to perform its obligations hereunder. Subject to the immediately preceding sentence, until this Agreement expires or is terminated, and Contractor has fully completed all of its obligations under this Agreement, Contractor shall not perform any work or services, enter into any employment contracts or any agreements with third-

parties, undertake any obligations or liabilities or expend any funds or engage in any activities except those which are directly related to the performance of Contractor’s obligations under this Agreement.

In the event Owner in any such proceeding is the prevailing Party and any of such costs, damages and expenses of Owner expended or incurred in connection with any such proceeding is required to be paid by Contractor to Owner, then in such event those costs of Owner, together with the costs, damages and expenses of Contractor, including attorney’s fees, expended or incurred by Contractor in connection with such proceeding shall be borne or paid solely by Contractor.
