 RECITALS: 

WHEREAS, CONSOL and CTH are party to that certain Water Supply and Services Agreement dated as of July 7, 2015 (the

AGREEMENTS: 
 NOW,
THEREFORE, in consideration of the mutual agreements, covenants, and conditions herein contained, CONSOL and CTH hereby agree as follows: 

ARTICLE 1 
 AMENDMENT

 1.1 Appendix I - Defined Terms. 

(a) Appendix I of the Water Agreement is hereby amended by deleting the following defined terms and their associated definitions:
(i) Operational Services; (ii) Treatment Fee; (iii) Treatment Services; (iv) Treatment Water; (v) Receipt Points; and (vi) Capital Expenses; 

(b) Appendix I of the Water Agreement is hereby amended by modifying the definition of “Water Services” to read as follows: 

“Water Services” means the Supply Services. 

1.2 Deletion of Sections 2.2 and 2.3. Sections 2.2 and 2.3 of the Water Agreement are hereby deleted from the Water Agreement in their
entirety and shall be replaced with the following: 
 2.2 [intentionally omitted] 

2.3 [intentionally omitted] 

1.3 Section 2.7(a) – Payment Terms; Disputed Charges. Section 2.7(a) of the Water Agreement is hereby deleted in its entirety
and replaced with the following: 
 (a) No later than 30 days after the end of each calendar month, CONSOL shall prepare and deliver to CTH,
an invoice for the Supply Fee incurred during such calendar month (or, in the case of the Shortfall Fee, the applicable quarter). 







 1.4 Section 2.9 – Arbitrator. Section 2.9 of the Water Agreement is hereby
deleted in its entirety and replaced with the following: 
 2.9 Arbitrator. In the event that the Parties
cannot reach agreement regarding any disputes regarding (i) amounts invoiced hereunder pursuant to Section 2.7 or Section 2.8 or (ii) the Water Sales Credit applicable to any Water Sales Agreement during each succeeding Term Year
following the initial Term Year, either Party may refer the remaining matters in dispute to the Philadelphia, Pennsylvania office of a mutually agreeable nationally recognized accounting firm (the “Arbitrator”) for review and final
determination by arbitration. Should such selected firm fail or refuse to agree to serve as Arbitrator within ten Business Days after receipt of a written request from any Party to serve, and should the Parties fail to agree in writing on another
replacement Arbitrator within five Business Days after the end of that ten-day period, or should no replacement Arbitrator agree to serve within 30 days after the original written request pursuant to this
Section 2.9, the Arbitrator shall be a nationally recognized accounting firm appointed by the Philadelphia office of the American Arbitration Association. The Arbitrator’s determination shall be made within 30 days after submission of the
matters in dispute and shall be final and binding on the Parties, without right of appeal. The Arbitrator shall act as an expert for the limited purpose of determining the specific disputed matters submitted by the Parties and may not award damages
or penalties to the Parties with respect to any matter. Each Party shall each bear its own legal fees and other costs of presenting its case. The fees, costs and expenses of the Arbitrator, shall be allocated between the Parties based upon the
percentage which the portion of the disputed matters not awarded to such Party bears to the amount actually contested by such Party. The provisions of this Section 2.9 shall survive the expiration or termination of this Agreement. 

1.5 Section 2.11 – Notices. Section 2.11 of the Water Agreement is hereby deleted in its entirety and replaced with the
following: 
 2.11 Notices. In the event either Party receives (a) a notice of non-compliance with, or violation of, any permit related to the Water Services or (b) any other notice or information related to the Water Services or terms of this Agreement (collectively,
“Notices”), the receiving Party shall, as soon as reasonably practical, forward such Notice to the other Party.
