“If this Agreement is terminated pursuant to the terms and conditions of this Agreement on or after December 31, 2032, then Producer shall have the option (to be exercised by providing written notice to Gatherer prior to the termination of the Agreement) to continue to receive the Services or a portion of the Services, under a new agreement, for all or any portion of its volumes of Saltwater on a year-to-year basis on the same terms and conditions as the most favorable terms and conditions under a then-effective agreement with any third party pursuant to which Gatherer provides a basket of services for an initial term (excluding any renewals or extensions of any kind) of at least [***] for volumes of Saltwater utilizing any System Segment located within the Dedicated Acreage (other than any pipeline facilities physically connected with or independent of a System Segment after the Effective Date, in each case, in connection with an acquisition, joint venture, or partnership by and between Gatherer and a third party), that are the same or substantially similar in nature to the basket of Services during the term hereunder, unless and until such third party agreement is terminated. For avoidance of doubt, the Services Gatherer is to offer Producer in accordance with the proceeding sentence shall only apply to Services on the Gathering System.

If the option to extend the term of this Agreement on a year-to-year basis pursuant to this Section 4.2 is exercised, any obligation of Gatherer to continue to provide the Services pursuant to such option shall not extend beyond December 31, 2042. Gatherer shall provide copies to Producer of any such third party agreements applicable to volumes of Saltwater accessing the Disposal System upon any notice of termination of this Agreement (whether such notice is delivered by Gatherer or Producer); provided, however, that to the extent Gatherer is prohibited by an obligation of confidentiality from disclosing any such third party agreement to Producer, then (a) Gatherer shall not be obligated to disclose such agreement to Producer until Gatherer has obtained the right to disclose such agreement and (b) Gatherer shall exercise reasonable efforts to obtain the right to disclose such agreement to Producer.”

(iii) Effective as of the Effective Date, Section 7.3 of the Produced Water Agreement—Beartooth Area is hereby deleted in its entirety and replaced with the following:

“Subject to the rest of the provisions of this Section 7.3, Producer will (i) use reasonable efforts to obtain access to electrical power at each CDP and (ii) provide electrical power to Gatherer at each CDP at Producer’s sole cost and expense. In designing and constructing its electrical facilities at each CDP, Producer will cooperate with Gatherer and take into account the amount of electrical power that is reasonably necessary for Gatherer’s facilities to receive Producer’s Saltwater at each such CDP. If a generator is necessary for electrical power to be used by Producer and Gatherer, then Producer shall procure, install, operate, and maintain such generator to fulfill the power requirements of the Parties and Gatherer shall pay its prorated portion of the reasonable capital costs (including reasonable rental and installation costs) therefor; provided, however, that Producer will continue to use all reasonable efforts to obtain access to electrical power at such CDP, thereby minimizing the time such generator is needed (rather than a local electric utility) to provide electrical power at such CDP.”

If the Person to whom Producer intends to sell, assign or otherwise Transfer all or any portion of the Dedicated Properties has a credit rating worse than Producer’s credit rating as of the Effective Date, then, Producer shall have the right to assign its rights under this Agreement, in whole or in part, as applicable, without the consent of Gatherer, to such Person if, as a condition precedent to such assignment, at Producer’s option, either: (A) Producer and the assignee execute an amendment to this Agreement with Gatherer that sets forth creditworthiness requirements to which Gatherer agrees such assignee will be subject under this Agreement for the remainder of the term, or (B) Producer remains liable for its obligations under this Agreement to the extent of such assignment, or (C) the assignee agrees to provide a letter of credit from a major U.S. commercial bank for the benefit of Gatherer in an amount equal to 60 days of the aggregated Fees under this Agreement that are reasonably estimated to become due and payable by assignee upon the assignment; provided that, upon such assignment, in each case of (A) and (C), Producer shall be released from its obligations under this Agreement to the extent of such assignment.”
