Section 2.2    Shipper’s Commitment. Subject to Section 2.3
through Section 2.5, Shipper exclusively dedicates and commits to deliver to Gatherer, as and when produced and purchased from Producer, all Dedicated Crude Oil into the Gathering System for the performance of the Services
under this Agreement. The Parties agree and acknowledge that the Crude Oil produced from the Excluded Wells is not subject to the dedication and commitment made by Shipper under this Agreement. 

Section 2.3    Conflicting Dedications. Producer and Shipper shall have the right to comply with each
of the Conflicting Dedications entered into by a non-Affiliated predecessor-in-interest to Producer that is applicable as of the
date of acquisition thereof to any Dedicated Property acquired after the Effective Date (but not any Conflicting Dedication entered into in connection with such acquisition); provided, however, that Producer and Shipper shall have the
right to comply with Conflicting Dedications only until the last Day of the Month in which the termination of such Conflicting Dedication occurs and neither Producer nor Shipper shall affirmatively extend the term of such Conflicting Dedication
beyond the minimum term provided for in the document evidencing such Conflicting Dedication or allow the term of such Conflicting Dedications to extend beyond its primary or initial term pursuant to the operation of an “evergreen” or other
similar provision if Producer or Shipper has the ability to terminate such Conflicting Dedication without incurring any costs, penalties or expenses. To Producer’s and Shipper’s knowledge, except for the Dedicated Crude Oil produced from
the Wells identified as “Wells Subject to Conflicting Dedications” on Exhibit D, the Dedicated Crude Oil is not, as of the Effective Date, subject to any Conflicting Dedication. If Dedicated Crude Oil produced from a Well on a Well
Pad is subject to a Conflicting Dedication that Producer and Shipper have the right to comply with under this Section 2.3, Producer and Shipper have the right, in complying with such Conflicting Dedication, to deliver the
Dedicated Crude Oil from such Well Pad in accordance with the Conflicting Dedication. 

Section 2.4    Producer’s and Shipper’s
Reservations. Producer and Shipper reserve the following rights with respect to Dedicated Crude Oil for themselves and for the operator of the relevant Dedicated Properties: (a) to operate Wells producing Dedicated Crude Oil as a reasonably
prudent operator in its sole discretion, including the right, but never the obligation, to drill New Wells, to repair and rework then-existing Wells, to renew or extend, in whole or in part, any Interest covering any of the Dedicated Properties, and
to cease production from or abandon any Well or surrender or release any such Interest, in whole or in part, whether or not capable of producing oil and gas under normal methods of operation; (b) to deliver or furnish to lessors and holders of
other existing similar burdens on production such Crude Oil as is required to satisfy the terms of the applicable leases or other applicable instruments; (c) to acquire Wells connected to existing gathering systems and to continue to deliver to
such gathering systems Crude Oil produced from such Wells; provided that, to the extent that Crude Oil from such Wells constitutes Dedicated Crude Oil and is not previously dedicated to a third party, then Producer or Shipper shall deliver a
Connection Notice to Gatherer with respect to any such Well not later than 30 Days after its acquisition, and thereafter shall deliver Crude Oil to such gathering system only until Gatherer has connected such Well to the Gathering System in
accordance with Section 3.3; (d) to pool, communitize or unitize Producer’s Interests with respect to Dedicated Crude Oil; provided that the Producer’s share of Crude Oil produced from such pooled,
communitized or unitized Interests shall be committed and dedicated to this Agreement; and (e) to deliver Dedicated Crude Oil that has been temporarily or permanently released from the dedication and

 commitment made by Producer and Shipper under this Agreement, including pursuant to
Section 3.3, Section 3.4, Section 3.5(c), Section 6.4(a), Section 6.5 or Section 9.2(d), to any Person other than Gatherer. 

Section 2.5    Covenant Running with the Land. The Parties intend that the dedication and commitment
made by Producer and Shipper under this Agreement be a covenant running with (a) the Dedicated Properties, as a burden on Producer’s title thereto and binding on
successors-in-interest in and to the Dedicated Properties, and (b) the Gathering System, as a benefit accruing to Gatherer’s title thereto and inuring to the
benefit of successors-in-interest to the Gathering System. Producer shall not Transfer any or all of its interest in any Dedicated Property unless (i) Producer
obtains and delivers to Gatherer a written acknowledgment by the Transferee in favor of Gatherer acknowledging that the Transferred Dedicated Property shall remain subject to this Agreement in all respects and (ii) each instrument of conveyance
expressly so states. Notwithstanding the foregoing, Producer shall be permitted to Transfer any Dedicated Property free of the dedication and commitment made by Producer and Shipper under this Agreement and without complying with the requirements of
this Section 2.5 in a Transfer in which a number of net acres of Dedicated Properties that, when added to the total of net acres of Dedicated Properties theretofore and, where applicable, simultaneously Transferred free and
clear of the dedication and commitment made by Producer and Shipper under this Agreement, does not exceed the aggregate number of net acres of Dedicated Properties acquired by Producer after the Effective Date, including in a transaction in which
Dedicated Properties are exchanged for other properties located in the Dedicated Acreage that would be subject to dedication hereunder; provided, however, that any such release of Dedicated Properties from such dedication and
commitment shall not include any Dedicated Crude Oil produced from any Well that is located on a Well Pad if the other Wells on such Well Pad are or have been connected to the Gathering System (whether producing,
shut-in, temporarily abandoned or which has been spud or as to which drilling, completion, reworking or other well operations have commenced) or that is located on a Well Pad if a Connection Notice has
previously been delivered by Producer for the CDP through which such Well Pad is produced. 

Section 2.6    Priority of Dedicated Crude Oil. Dedicated Crude Oil tendered at the Receipt Points on
the Gathering System on any Day shall be Firm Capacity Crude Oil. Shipper’s Crude Oil that is not Dedicated Crude Oil that is tendered at the Receipt Points on any Day shall be Interruptible Crude Oil unless otherwise agreed to by Gatherer.

Section 3.7, Section 3.8 and Section 3.9. 
 Gatherer shall
act as a Reasonable and Prudent Operator in performing the Services and any of its other obligations under this Agreement. 

Section 3.2    Development Plan; Gathering System Plan; Exchange and Review of
Information. 
 (a)    Producer has provided to Shipper and Gatherer, and shall provide to Shipper and Gatherer
prior to October 15 of each year, copies of a drilling plan for the following calendar year (each, a “Development Plan”), which shall describe the planned drilling and production activities relating to Producer’s
Interests in the Dedicated Acreage during such year, including good faith and reasonable forecasts of the volume of Dedicated Crude Oil expected to be produced through all CDPs during such year, and including the location of all Planned CDPs
expected to be connected to the Gathering System during such year, and the projected spud date, projected completion date and projected volumes for each New Well that is expected to be completed and to produce through each CDP during such year. Each
time Producer materially updates the Development Plan, it shall provide a copy of such updated Development Plan to Shipper and Gatherer, but not less frequently than on a calendar quarter basis. 

(b)    Gatherer has previously provided Producer and Shipper with a copy of its current Gathering System plan describing
and/or depicting the Gathering System, including all pipelines, all Receipt Points and Delivery Points, and all stabilization, blending and storage facilities and other major physical facilities, together with their locations, sizes and other
physical specifications, operating parameters, capacities, and other relevant specifications, and together with a schedule for completing the construction and installation of the planned portions thereof, in each case as currently in existence,
under construction, or planned (such plan, as updated as hereinafter provided, the “Gathering System Plan”). The Gathering System Plan

AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH BRACKETS AND THREE ASTERISKS [***] 

 
 shall state, for each planned pipeline, the estimated volume of Line Fill that will be
required in order to put such pipeline into operation. Based on the Development Plans and such other information about the expected development of the Dedicated Properties as shall be provided to Gatherer by Producer, as well as forecast Delivery
Point nominations received from Shipper from time to time, Gatherer shall periodically update the Gathering System Plan. Without limiting the generality of the foregoing, Gatherer shall ensure that the Gathering System Plan reflects all Planned CDPs
included in each Development Plan not later than 30 Days after such Development Plan is delivered to Gatherer. Gatherer shall provide a copy of the Gathering System Plan to Producer and Shipper and their respective representatives from time to time
and shall make representatives of Gatherer available to discuss the Gathering System Plan from time to time with Producer and Shipper and their respective representatives. Gatherer shall provide Producer and Shipper updates not less frequently than
monthly on the progress of work on all facilities necessary to connect Planned CDPs to the Gathering System and to provide the Services associated with such Crude Oil, as set forth in the then-current Gathering System Plan. 

(c)    The Parties recognize that all information provided by Producer to Gatherer or Shipper regarding its intentions
with respect to the development of the Dedicated Properties, is subject to change and revision at any time at the discretion of Producer, and that such changes may impact the timing, configuration and scope of the planned activities of Gatherer. The
exchange of such information and any changes thereto shall not give rise to any rights or liabilities as among the Parties except as expressly set forth in this Agreement, and Gatherer shall determine at its own risk the time at which it begins to
work on and incur costs in connection with particular Gathering System expansion projects, including the acquisition of rights of way, equipment and materials. Without limiting the generality of the foregoing, Producer has no obligation to Shipper
or Gatherer under this Agreement to develop or produce any Crude Oil from the Dedicated Properties or to pursue or complete any drilling or development on the Dedicated Properties other than the terms specifically stated in this Agreement. 

Section 3.3    Expansion of Gathering System; Connection of Wells; Delivery Points. 

(a)    Gatherer shall design and develop the Gathering System for the purpose of providing the Services as and when needed
to support the upstream development of the Planned CDPs, and Gatherer shall be obligated, at its sole cost and expense, subject to the provisions of this Agreement, to procure, construct, install, own and operate the Gathering System so as to timely
connect the Planned CDPs to the Gathering System, connect the Gathering System to the Delivery Points and timely commence providing the full scope of the Services with respect to all Dedicated Crude Oil produced from all CDPs, including the Planned
CDPs from and after their connection to the Gathering System, all in accordance with this Section 3.3; provided that the foregoing shall not preclude Gatherer from also designing and developing the Gathering System
to accommodate Third Party Crude Oil. 
 (b)    Producer shall from time to time give notice (a “Connection
Notice”) to Gatherer (with a copy to Shipper) of each CDP that Producer intends to construct and install (or a CDP that is subject to a Conflicting Dedication that has expired or will expire, or that Producer or Shipper has terminated
or will terminate, prior to the applicable Completion Deadline) through which Dedicated Crude Oil will be produced (each, a “Planned CDP”). Each

 Connection Notice shall set forth the target completion date for drilling and completion
of the initial Well to produce through such Planned CDP (the “Target Completion Date”). Following delivery of a Connection Notice with respect to a Planned CDP, Gatherer shall cause the necessary facilities to be constructed
to connect such CDP to the Gathering System and to commence the Services with respect to Dedicated Crude Oil produced from such Planned CDP by the date that is (i) in the case of a Planned CDP that (A) is located two miles or less from the
then-existing Gathering System at the time of such Connection Notice and (B) the Target Completion Date for which is during the months of May through October, 90 Days after the date of Producer’s delivery of such Connection Notice and
(ii) in the case of a Planned CDP that is (A) located greater than two miles from the then-existing Gathering System at the time of such Connection Notice or (B) the Target Completion Date for which is during the months of November
through April, 180 Days after the date of Producer’s delivery of such Connection Notice (such date, the “Completion Deadline”). Gatherer shall provide Producer and Shipper notice promptly upon Gatherer’s becoming
aware of any reason to believe that it may not be able to connect a Planned CDP to the Gathering System by the Completion Deadline therefor or to otherwise complete all facilities necessary to provide the full scope of the Services with respect to
all Dedicated Crude Oil produced through such Planned CDP by the Completion Deadline therefor. If and to the extent Gatherer is delayed in completing and making available such facilities by a Force Majeure event or any action of Producer that is
inconsistent with the cooperation requirements of Section 3.6, then the Completion Deadline for such connection shall be extended for a period of time equal to that during which Gatherer’s completion and making
available of such facilities was delayed by such events or actions. If such facilities are not completed and made available by the Completion Deadline (as may be extended in accordance with Section 3.5(b)), as Shipper’s and
Producer’s sole and exclusive remedies for such delay: 
 (i)    Gatherer shall truck the Dedicated
Crude Oil produced through such CDP subject to the requirements of Section 6.4 at Gatherer’s sole cost and expense from the Completion Deadline (but without giving any effect to any extension of the Completion Deadline
as a result of Force Majeure) until the Gathering System is connected to such CDP; and 
 (ii)    at
Producer’s option, the Dedicated Crude Oil produced from the CDP and any future Wells drilled within the same DSU shall be permanently released from the dedication and commitment made by Producer and Shipper under this Agreement. 

(c)    To the extent that the CDP connection is required sooner than the Completion Deadline determined as set forth
above, the Parties shall meet and discuss the issues and potential additional costs associated with acceleration of such connection, and shall use reasonable efforts mutually to agree upon an accelerated connection timing. If Producer is willing to
pay for the additional costs involved with accelerating a connection, Gatherer shall use reasonable efforts to complete the CDP connection within such accelerated timing. 

(d)    The Parties agree and acknowledge that Producer has as of the Effective Date delivered Connection Notices to
Gatherer with respect to certain Planned CDPs set forth in the Development Plan effective as of the Effective Date. Such Connection Notices shall be deemed to have been given for each such Planned CDP on the Effective Date.

 (e)    Gatherer shall design and construct the
initial Delivery Point at its sole cost and expense. Gatherer shall be obligated, at Gatherer’s cost, to provide connections to the Delivery Points set forth on Exhibit B or within the Development Plan. If Shipper specifies that
Dedicated Crude Oil is to be delivered to a Delivery Point not described on Exhibit B or within the Development Plan that is not at such time connected to the Gathering System, Gatherer shall, at Shipper’s sole actual cost, risk and
expense, provide a connection to such Delivery Point. Such costs shall be allocated pro rata with any third party shipper that requests utilization of such additional Delivery Point. Gatherer shall proceed with due diligence and in good faith to
obtain the necessary governmental authorizations and to enter into the necessary third party agreements (any such agreement to be on terms acceptable to Gatherer) to connect the Gathering System to each such new delivery point. All such Delivery
Points shall be provided with all interconnection facilities and other Delivery Point facilities (including any Measurement Facilities), and with sufficient capacities, necessary to permit Dedicated Crude Oil to be redelivered at such Delivery Point
in accordance with this Agreement (with all expansions of capacity at such new Delivery Points, not including the Delivery Points described on Exhibit B or within the Development Plan, being at Shipper’s sole actual cost, risk and
expense). Subject to the foregoing, Gatherer shall connect each CDP to the Gathering System such that Crude Oil from such CDP can be redelivered to the Delivery Points. Upon completion of the connection of the Gathering System to such new delivery
point pursuant to this Section 3.3(e) and such connection becoming operational, the point of interconnection between the Gathering System and such new delivery point shall thereafter be a Delivery Point under this Agreement. The Parties shall
discuss Shipper’s plans and timing for all new Delivery Point connections on a Monthly basis. 

Section 3.4    Timing for Completion and Placement into Service of Initial Gathering System. As of the
Effective Date, Gatherer has completed the initial design, engineering, construction and initial startup and operation of the Gathering System at Gatherer’s sole cost and expense. 

Section 3.5    Right of Way and Access. 

(a)    Gatherer is responsible for the acquisition of rights of way, crossing permits, licenses, use agreements, access
agreements, leases, fee parcels and other rights in land necessary to construct, own and operate the Gathering System, and all such rights in land shall be solely for use by Gatherer and shall not be shared with Producer, except as otherwise agreed
by Gatherer; provided that Producer agrees to grant, without warranty of title, either express or implied, to the extent that it has the right to do so without the incurrence of expense, an easement and right of way upon the lands covered by
the Dedicated Properties, for the sole purpose of installing, using, maintaining, servicing, inspecting, repairing, operating, replacing, disconnecting and removing all or any portion of the Gathering System, including any pipelines, meters and
other equipment necessary for the performance of this Agreement; provided, further, that the exercise of these rights by Gatherer shall not unreasonably interfere with Producer’s lease operations or with the rights of owners in
fee, and will be subject to Producer’s safety and other reasonable access requirements applicable to Producer’s personnel. Producer shall not have a duty to maintain the underlying agreements (such as leases, easements and surface use
agreements) that such grant of easement or right of way to Gatherer is based upon, and such grants of easement or right of way will terminate if Producer loses its rights to the property,

 REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY FILED WITH THE SECURITIES AND EXCHANGE COMMISSION, 

AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH BRACKETS AND THREE ASTERISKS [***] 

 
 regardless of the reason for such loss of rights. Notwithstanding the foregoing,
(i) Producer will assist Gatherer to secure replacements for such terminated grants of easement or right of way, in a manner consistent with the cooperation requirements of Section 3.6, (ii) to the extent that Producer
agrees that Gatherer’s Measurement Facilities may be located on Producer’s Well Pad sites, Producer shall be responsible for obtaining any necessary rights to locate such Measurement Facilities on such Well Pad sites and
(iii) Producer shall use reasonable efforts to involve Gatherer in Producer’s negotiations with the owners of lands covered by the Dedicated Properties so that Producer’s surface use agreements and Gatherer’s rights of way with
respect to such lands can be concurrently negotiated and obtained. 
 (b)    If Gatherer cannot obtain the rights of way
(on terms and conditions reasonably acceptable to Gatherer after diligent pursuit thereof) necessary to connect any Planned CDP within 45 Days of delivery of a Connection Notice, then Gatherer shall so notify Producer in writing (the
“Easement Notice”) within 45 Days of delivery of the Connection Notice. Producer shall have the right (but not the obligation) to obtain, at its sole cost and expense, such rights of way generally in the format of
Gatherer’s standard right of way agreement within 45 Days of delivery of such Easement Notice. Gatherer’s form of right of way agreement is attached as Exhibit C. The right of way agreement utilized by Producer can have
modifications to the Exhibit C format as long as it does not materially change or reduce the rights or obligations under such right of way agreement. If Producer obtains such rights of way in accordance with the immediately preceding
sentence, Producer shall assign such right of way to Gatherer, and Gatherer’s connection obligations for the applicable CDP shall continue in accordance with the terms of this Agreement; provided, however, that the time required
for Gatherer to connect the applicable CDP shall be extended by a number of days commencing on the date of delivery of the Easement Notice and ending on the date that Gatherer receives from Producer the assignment of all such rights of way so
obtained by Producer (together with executed originals of all such rights of way). In such event, Gatherer shall pay Producer for such rights of way an amount per rod equal to the average price per rod paid by Gatherer for the purchase of rights of
way in the Dedicated Acreage during the preceding 12 month period. If Gatherer has not purchased right of way within the Dedicated Acreage during the previous 12 months, then Gatherer shall pay Producer for such rights of way an amount per rod equal
to the amount per rod paid by Gatherer under its most recent purchase of rights of way in the Dedicated Acreage. 

(c)    In the event that Producer fails to obtain such rights of way during such 45 Day period, Gatherer shall be
responsible for trucking Crude Oil from such Planned CDP to the Delivery Points subject to and in accordance with Section 6.4, and Producer shall have the option, upon written notice to Gatherer, to permanently release the
entire DSU or any portion thereof associated with the Wells connected to such CDP from the dedication and commitment made by Producer and Shipper under this Agreement. 

Section 3.6    Cooperation. Because of the interrelated nature of the actions of Producer
and Gatherer required to obtain the necessary Permits from the appropriate Governmental Authorities and the necessary consents, rights of way and other authorizations from other Persons necessary to drill and complete each Well and construct the
required extensions of the Gathering System to each Planned CDP, Producer and Gatherer agree to work together in good faith to obtain such Permits, authorizations, consents and rights of way as expeditiously as

 reasonably practicable. Producer and Gatherer further agree to cooperate with each other
and to communicate regularly regarding their efforts to obtain such Permits, authorizations, consents and rights of way. 

Section 3.7    Central Processing Facility Trucked Volumes. Gatherer shall construct,
own, operate and maintain, at its sole cost and expense, four truck ACT (Automatic Custody Transfer Unit) offloading facilities with the design capacity to offload 20,000 Barrels of Crude Oil per Day at the Central Processing Facility for use
exclusively by Shipper to offload trucked Crude Oil primarily (but not exclusively) to provide blend stock to blend with the Crude Oil delivered to Gatherer at the Receipt Points in order to reduce the API Gravity of such Crude Oil. If the initial
four truck ACT offloading facilities provided by Gatherer are not capable of providing the offloading services requested by Shipper under this Agreement, then Gatherer shall install, at its sole cost and expense, up to an additional two ACT
offloading facilities to meet Shipper’s offloading service requests; provided that Gatherer shall not have an obligation to provide additional ACT offloading facilities at its sole cost and expense if such facilities are proven to have
an actual aggregate capacity in excess of 20,000 Barrels of Crude Oil per Day. Any Crude Oil delivered by truck pursuant to this Section 3.7 shall be received at the Central Processing Facility and shall not be subject to
the Gathering Fee or the Stabilization and Blending Fee. Gatherer shall provide the Services associated with such trucked volumes of Crude Oil in accordance with Shipper’s nomination for the applicable Month. 

Section 3.8    Stabilization. 

(a)    Gatherer shall construct, own, operate and maintain, at its sole cost and expense, the necessary stabilization
equipment and facilities at the Central Processing Facility to provide the stabilization services for both volumes received into the Gathering System at the Receipt Points and volumes received at the truck offloading facilities at the Central
Processing Facility in accordance with this Section 3.8. 
 (b)    Gatherer shall provide
Shipper with stabilization services with an inlet capacity of [***] Barrels of Crude Oil per Day in order to reduce the RVP of Shipper’s Crude Oil from the Maximum RVP to the RVP(s) specified in Shipper’s nomination applicable for the
Month; provided that Gatherer shall not be required to reduce the RVP to Shipper’s Crude Oil below [***] psig at the Delivery Points. It is understood by the Parties that reducing the RVP may increase the PLA volume; provided that
the foregoing shall not limit or in any way relieve Gatherer of its obligation to act as a Reasonable and Prudent Operator. Gatherer shall deliver any gas stabilizer overhead vapors to the inlet of the Natural Gas Processing Plant for Shipper’s
account at no charge to Producer or Shipper under this Agreement. All stabilization services pursuant to this Section 3.8 shall be provided at Shipper’s direction and in accordance with Shipper’s nomination for
the applicable Month. 
 Section 3.9    Storage and Blending Services. 

(a)    Gatherer shall own, operate and maintain, at its sole cost and expense, three Crude Oil storage tanks capable of in-tank blending with a Tankage Shell Capacity of 60,000 Barrels, 60,000 Barrels and 120,000 Barrels and with a working storage capacity of 50,000 Barrels, 50,000 Barrels and 100,000 Barrels, respectively
(collectively, the “Storage

 Tanks”). Gatherer shall provide Shipper with dedicated storage and
blending services (the “Storage and Blending Services”) utilizing the maximum Tankage Shell Capacity of the Storage Tanks through December 31, [***], and
year-to-year thereafter; provided that Shipper may elect to discontinue the Storage and Blending Services at any time after December 31, [***] by giving 90
Days prior written notice to Gatherer and thereafter shall not be required to pay the Storage Fee associated therewith. Shipper shall continue to be provided the Storage and Blending Services to store any volumes of Crude Oil, whether or not such
Crude Oil is considered Dedicated Crude Oil under this Agreement. Shipper shall be entitled to deliver Crude Oil into the Storage Tanks directly from the Gathering System or from a truck offloading facilities at the Central Processing Facility
whether or not stabilization services have been provided in accordance with Section 3.8 for such volumes of Crude Oil. In addition to the foregoing and without prejudice to Section 3.9(d), upon Shipper’s
request, Gatherer shall communicate with Shipper regarding available storage capacity and Shipper and Gatherer shall use reasonable efforts to negotiate the terms and conditions applicable to such available storage capacity, including the storage
fees associated therewith. 
 (b)    Gatherer shall own, operate and maintain (including any Storage Tank cleaning
reasonably requested by Shipper) the Storage Tanks and accept Crude Oil into and deliver Crude Oil out of the Storage Tanks. All blending within the Storage Tanks and deliveries into and out of the Storage Tanks shall be provided at Shipper’s
direction and in accordance with Shipper’s nomination for the applicable Month. Gatherer shall use reasonable efforts to provide Shipper with daily readings of the volume, RVP and API Gravity of the Crude Oil in each of the Storage Tanks.
Shipper shall not be limited (except by storage capacity) on the number of turnovers or volumes of Crude Oil delivered into and out of the Storage Tanks on any Day. 

(c)    Upon termination or expiration of this Agreement or if Shipper discontinues the Storage and Blending Services
pursuant to Section 3.9(a), then Gatherer shall promptly remove and deliver all volumes of Crude Oil (if any), including any Line Fill or other tank heel, stored in any of the Storage Tanks to Shipper at the Delivery Points. 

(d)    At the request of Shipper at any time during the term of this Agreement, Gatherer shall construct additional
tankage and Shipper shall pay the Storage Fee associated with the requested Tankage Shell Capacity for a minimum term of five years for such additional tankage. Any additional tankage built by Gatherer pursuant to this Section 3.9(d) shall
thereafter be considered part of the Storage Tanks. 
 (e)    Gatherer shall have the right, at its sole option, at any
time and from time to time, to substitute any Storage Tank for one of the other Storage Tanks (any such tank, a “Substitute Tank”) by providing Shipper notice thereof no later than 30 days prior to the date on which such
substitution(s) are to take effect (unless due to an event of Force Majeure, emergency, or otherwise mutually agreed). Any Substitute Tank will be of equal or greater capacity (in the aggregate) to the Storage Tank(s) being substituted, with equal
or better connectivity and capabilities.

Gatherer each Month in accordance with the terms of this Agreement, for all Services provided by Gatherer during such Month, an amount equal to the sum of the fees (collectively, the “Fees”) set forth on Exhibit I.

 ARTICLE 6 
 CERTAIN
RIGHTS AND OBLIGATIONS OF PARTIES 
 Section 6.1    Operational Control of
Gatherer’s Facilities. Gatherer shall design, construct, own, operate and maintain the Gathering System at its sole cost and risk. Gatherer shall be entitled to full and complete operational control of its facilities and shall
be entitled to schedule deliveries and to operate and reconfigure its facilities in a manner consistent with its obligations under this Agreement. 

Section 6.2    Maintenance. Gatherer shall be entitled, without liability, to interrupt
its Gathering System performance hereunder to perform necessary or desirable inspections, pigging, maintenance, testing, alterations, modifications, expansions, connections, repairs or replacements to its facilities as Gatherer deems necessary
(“Maintenance”), with reasonable notice provided to Producer, except in cases of emergency where such notice is impracticable or in cases where the operations of Producer and Shipper will not be affected. Gatherer shall use
reasonable efforts to schedule any Maintenance to minimize the effect on providing the Services pursuant to this Agreement. Before the beginning of the calendar year, Gatherer shall provide Producer in writing with a projected schedule of the
Maintenance to be performed during the year and the anticipated date of such Maintenance. Gatherer shall truck Producer’s Dedicated Crude Oil subject to and in accordance with Section 6.4 during all times of
Maintenance on the Gathering System. 
 Section 6.3    Capacity Allocations on the
Gathering System. Subject to the capacity allocations set forth in this Section 6.3, Gatherer has the right to contract with other Persons for the delivery of Third Party Crude Oil to the Gathering System, including the
delivery of Firm Capacity Crude Oil. If the volume of Crude Oil available for delivery into any System Segment exceeds the capacity of such System Segment at any point relevant to Gatherer’s service to Producer hereunder, then Gatherer shall
interrupt or curtail receipts of Crude Oil in accordance with the following: 
 (a)    First, Gatherer shall
curtail all Interruptible Crude Oil prior to curtailing Firm Capacity Crude Oil. 
 (b)    Second, if additional
Gathering System curtailments are required beyond Section 6.3(a), Gatherer shall curtail Firm Capacity Crude Oil on the Gathering System. In the event Gatherer curtails some, but not all, Firm Capacity Crude Oil on a particular Day, Gatherer

 Gatherer in its sole discretion to include estimated volumes from New Wells that are
connected to a Receipt Point that were not producing during the previous Month, 
 provided that Gatherer shall truck Shipper’s
Dedicated Crude Oil subject to and in accordance with Section 6.4 during all times of curtailment on the Gathering System. 

Section 6.4    Trucking. 

(a)    If Gatherer is not able to receive volumes of Dedicated Crude Oil into the Gathering System up to the Maximum DSU
Volume at the Receipt Points on each DSU on any Day for any reason, including (i) Force Majeure, (ii) delays in construction of Planned CDPs under Section 3.3(b) and of the initial Gathering System under
Section 3.4, (iii) inability to obtain right of way under Section 3.5(c), (iv) Maintenance under Section 6.2, (v) curtailment under Section 6.3, (vi) insufficient
pressures at the Receipt Points under Section 7.1 or (vii) lack of electrical facilities under Section 7.4, then Gatherer shall truck such volumes to the Central Processing Facility, and
Shipper shall pay the Fees as if such volumes had been gathered by Gatherer into the Gathering System; provided, however, that the volumes that Gatherer must truck on any Day from any DSU shall not exceed the Maximum DSU Volume minus
actual Barrels received at the Receipt Points on the Gathering System on such DSU on such Day. Within 30 Days of commencing trucking operations pursuant to this Section 6.4(a), Gatherer shall provide Shipper with a written explanation
detailing the reason for its inability to receive volumes into the Gathering System, and its commitment to diligently pursue a plan to achieve delivery of all volumes of Crude Oil tendered by Shipper up to the Maximum DSU Volume for any DSU through
the Gathering System at each affected DSU. The Parties may mutually agree to review capacity in excess of the Maximum DSU Volume for any DSU. Notwithstanding the foregoing, in no event shall Gatherer be required to provide trucking services pursuant
to this Section 6.4(a) for a period in excess of [***] consecutive months per DSU; provided that if Gatherer is not able to receive volumes up to the Maximum DSU Volume at the Receipt Points on each DSU on any Day for any reason
other than Force Majeure and, as a result, Shipper has excess volume that is being curtailed on the Gathering System for a period in excess of [***] months, then Gatherer shall (at Shipper’s request and option) either (A) permanently
release the entire DSU or any portion thereof associated with the Wells connected to such CDP from the dedication and commitment made by Producer and Shipper under this Agreement or (B) continue to truck excess volumes up to the Maximum DSU
Volume beyond the aforementioned [***] month period and charge the actual third party invoiced costs to Shipper for such trucking in lieu of the Gathering Fee (but Gatherer shall continue to receive the other applicable Fees for all such Crude Oil).
For the avoidance of doubt, such actual third party invoiced costs to truck shall not be limited to the Gathering Fee. 

(b)    For volumes of Crude Oil that Gatherer is unable to receive into the Gathering System for any reason that Gatherer
is not obligated to pick up by truck pursuant to Section 6.4(a), Gatherer shall, if requested by Shipper, truck such volumes and charge actual third party invoiced costs to Shipper for such trucking in lieu of the Gathering Fee (but Gatherer
shall continue to receive the other applicable Fees for all such Crude Oil). For the avoidance of doubt, such actual third party invoiced costs to truck shall not be limited to the Gathering Fee.

 Section 6.5    Temporary
Releases. In addition to any other rights and remedies available to Producer or Shipper under this Agreement or at law or in equity, if Gatherer fails or is unable or unwilling for any reason (including Force Majeure) to accept all volumes of
Dedicated Crude Oil tendered by or on account of Shipper pursuant to this Agreement and provide the Services in accordance therewith, including any failure or inability to truck volumes of Crude Oil in accordance with
Section 6.4, then the volumes of Dedicated Crude Oil in excess of what Gatherer is willing and able to accept shall be temporarily released from the dedication and commitment made by Producer and Shipper under this
Agreement. Producer and Shipper may immediately deliver such volumes to any Person other than Gatherer, and Producer and Shipper shall have the right to enter into commitments to deliver such volumes of Dedicated Crude Oil to other third party
gatherers, such commitments to be for no longer than reasonably necessary under the circumstances, as determined by Producer and Shipper in their sole discretion. 

Section 6.6    Line Fill. 

(a)    Shipper shall be required to provide, or cause to be provided, without cost to Gatherer, its pro rata share of Line
Fill, based on the total volume of Crude Oil in Barrels received from or on account of Shipper divided by the total volume of Crude Oil in Barrels received from all shippers on the Gathering System. 

(b)    Gatherer shall calculate Shipper’s pro rata share of Line Fill Monthly and provide Shipper with a balance
statement substantially in the form of Exhibit F. Gatherer shall deliver this Monthly balance statement with its Monthly statement to be provided pursuant to Section 12.1 If Shipper’s pro rata share of the Line
Fill is increased as a result of such calculation, Shipper shall promptly provide, or cause to be provided, without cost to Gatherer, additional volumes of Crude Oil to meet such requirement. If Shipper’s pro rata share of the Line Fill is
reduced as a result of such calculation, Gatherer shall promptly deliver the excess amount of Crude Oil to Shipper, less PLA, at the applicable Delivery Points and Shipper shall pay the Gathering Fee in effect during such Month of delivery to the
Delivery Points on such excess Line Fill. 
 (c)    Shipper’s share of the Line Fill shall be held by Gatherer in
the Gathering System returned to Shipper following the termination of this Agreement. Within 60 Days following the termination or expiration of this Agreement, (a) Gatherer shall deliver and Shipper shall receive such Line Fill, less PLA, at
the applicable Delivery Points and (b) Shipper shall pay the Gathering Fee in effect on the termination of this Agreement on such Line Fill for the delivery of the same to the applicable Delivery Points. 

ARTICLE 7 
 PRESSURES;
PRODUCER’S FACILITIES; ELECTRICITY 
 Section 7.1    Pressures at Receipt
Points. Shipper shall deliver or cause to be delivered Crude Oil to each Receipt Point on the Gathering System from atmospheric tanks or from low pressure separation at sufficient pressure to enter Gatherer’s Receipt Point pump on the
Gathering System against its operating pressure, except that Gatherer shall not be obligated to gather Crude Oil at pressures in excess of the maximum allowable operating pressure of the

 Gathering System at such Receipt Point, as determined by Gatherer in its sole
discretion. Gatherer shall operate its measurement and Receipt Point pump at a pressure that allows Producer to deliver Crude Oil directly from its atmospheric tanks or low pressure separation into the Gathering System without additional pumps;
provided that such atmospheric tanks have a minimum of four feet of hydrostatic head or low pressure separation at the low liquid level to allow Gatherer’s pumps to attain proper suction pressure. 

Section 7.2    Pressures at Delivery Points. The Gathering System shall be designed for
and shall be operated by Gatherer at a discharge pressure sufficient to effect delivery of all of Shipper’s Dedicated Crude Oil to the Delivery Point(s). 

Section 7.3    Producer Facilities. 

(a)    Producer, at its own expense, shall construct, equip, maintain and operate all facilities necessary to deliver
Dedicated Crude Oil to Gatherer at the Receipt Points. Producer shall install and maintain sufficient pressure regulating equipment upstream of the Receipt Points on the Gathering System in order to keep the pressure of the Crude Oil delivered to
Gatherer at such Receipt Points from exceeding the maximum allowable operating pressure of the Gathering System at the applicable Receipt Point, as determined by Gatherer in its sole discretion and stated in the Gathering System Plan. Such equipment
shall include low pressure separation facilities and atmospheric tankage upstream of the Receipt Points. 

(b)    Producer shall have the right to install facilities and flow volumes attributable to Producer’s interests in
operated and non-operated wells outside, but on DSUs that are contiguous with, the Dedicated Acreage, allowing such wells to flow into existing CDPs or to new CDPs mutually agreed among Producer, Shipper and
Gatherer where Gatherer shall provide a meter and tap at Gatherer’s sole cost and expense. Producer shall provide a list of wells from outside, but on DSUs that are contiguous with, the Dedicated Acreage that will be connected to existing CDPs
or to new CDPs in accordance with this Section 7.3(b). 
 Section 7.4    Electrical
Facilities. To the extent that Producer has electrical power available at a CDP in excess of Producer’s own uses, as Producer determines in its reasonable discretion, Producer will supply electrical power without cost to Gatherer at each
such CDP for Gatherer’s Measurement Facilities and pumps. If Gatherer requires additional electrical power at such site, then Gatherer shall either install, own, operate and maintain a generator at its sole cost and expense or shall truck such
volumes from such CDP at its sole cost and expense subject to and in accordance with Section 6.4. 
 ARTICLE 8

 NOMINATIONS, BALANCING AND PLA ALLOCATION 

Section 8.1    Gatherer Notifications. On or before the 17th Day prior to the end of each
Month, Gatherer shall provide written notice to Shipper of Gatherer’s good faith estimate of any capacity allocations or curtailments for any System Segment, if any, that, based on then currently available information, Gatherer anticipates will
be required or necessary during the next Month, including as a result of any Maintenance. Gatherer shall use all reasonable efforts to provide 48 hours advance notice of any actual event requiring allocation or curtailment, including

 Maintenance. No later than 17 Business Days prior to the end of each Month,
Gatherer shall notify Producer of the estimated PLA and Line Fill expected to be used in the Gathering System for the following Month of Crude Oil delivered at the Receipt Points, after taking into consideration the anticipated operational
efficiencies and operational mode of the Gathering System. 
 Section 8.2    Nominations. On or
before the fifteenth Day prior to the end of each Month, Shipper shall provide to Gatherer nominations for (a) deliveries of Dedicated Crude Oil to the Receipt Points, (b) deliveries of Crude Oil to the specified Delivery Points to be
delivered during the next Month, (c) any anticipated stabilization and blending services needed with respect to such Crude Oil, including the level of RVP reduction that Shipper requires at the Delivery Points and (d) deliveries into and
out of the Storage Tanks. Shipper shall have the right to change such nominations at any time subject to the requirements of the Persons receiving Crude Oil at or downstream of the Delivery Points and subject to changes in wellhead volumes being
delivered into the Gathering System. Gatherer shall use reasonable efforts to accommodate any changes made to Shipper’s Monthly nominations. 

Section 8.3    Balancing. Gatherer will maintain records of any Daily and Monthly
variances (“Imbalances”) between the volume of Dedicated Crude Oil received at the Receipt Points and the volumes of Crude Oil delivered at the Delivery Points (after PLA and Line Fill allocated to Shipper in accordance with
Section 6.6 and Section 8.4). Shipper shall make such changes in its nominations as Gatherer may from time to time reasonably request to maintain Daily and Monthly balances or to correct an
Imbalance. Shipper shall reimburse Gatherer for any cost, penalty or fee arising from any Imbalance assessed against Gatherer by any Person receiving Dedicated Crude Oil downstream of the Delivery Points, except to the extent such Imbalance was
caused by Gatherer. Upon the termination of this Agreement or at such other time as Shipper and Gatherer agree, Shipper and Gatherer shall volumetrically balance any cumulative Imbalance. 

Section 8.4    Allocation of PLA. PLA shall be allocated to Shipper based on its pro rata share of such
PLA, with such allocation calculated based on the total volume of Crude Oil in Barrels received from or on account of Shipper at the Receipt Points divided by the total volume of Crude Oil in Barrels received from all shippers’ receipt points
on the Gathering System. Gatherer trucked volumes from a Receipt Point shall be considered Receipt Point volumes and any losses that occur while the Crude Oil is on the truck shall be included in the above PLA calculation. Shipper or third party
trucked volumes delivered to the truck offloading facilities at the Central Processing Facility shall be considered a Receipt Point at such truck offloading facilities with the upstream losses incurred on the truck not included in the above PLA
calculation. 
 ARTICLE 9

 Section 10.2    Notice
of Measurement Facilities Inspection and Calibration. Each of Shipper and Gatherer shall give two days’ notice to the other in order that the other may, at its option, have representatives present to observe any reading, inspecting,
testing, calibrating, proving or adjusting of Measurement Facilities used in measuring or checking the measurement of receipts of Crude Oil under this Agreement. Gatherer shall provide at least two Days advance notice to Shipper of all provings and
related calibration activities for any LACT meter unit. The data from such Measurement Facilities shall remain the property of the Measurement Facilities’ owner, but copies of such records shall, upon written request, be submitted to the
requesting Party for inspection and verification. 
 Section 10.3    Measurement Accuracy
Verification. 
 (a)    Gatherer shall calibrate meters as often as required, as determined by Gatherer in accordance
with standard industry practices and applicable regulatory standards to reasonably assure accurate measurement, but at least once per month for any Receipt Point with a LACT meter unit. 

(b)    If, during any test of the Measuring Facilities, an adjustment or meter proving error is found which results in an
incremental adjustment to the calculated flow rate through each meter in excess of 0.25% of the adjusted flow rate (whether positive or negative and using the adjusted flow rate as the percent error equation denominator), then any previous
recordings of such equipment shall be corrected to zero error for any period during which the error existed (and which is either known definitely or agreed to by Shipper and Gatherer) and the total flow for the period redetermined in accordance with
the provisions of Section 10.5. If the period of error condition cannot be determined or agreed upon between Shipper and Gatherer, such correction shall be made over a period extending over the last one half of the time
elapsed since the date of the prior test revealing the 0.25% error. 
 (c)    If, during any test of any Measurement
Facilities, an adjustment or meter proving error is found which results in an incremental adjustment to the calculated flow rate which does not exceed 0.25% of the adjusted flow rate, all prior recordings and data shall be considered to be accurate
for quantity determination purpose. 
 Section 10.4    Special Tests. If Shipper or
Gatherer desires a test of any Measurement Facilities not scheduled by a Party under the provisions of Section 10.3, two days advance notice shall be given to the other and both Shipper and Gatherer shall cooperate to
secure a prompt test of the accuracy of such equipment. If the Measurement Facilities tested are found to be within the range of accuracy set forth in Section 10.3(b), then the Party that requested the test shall pay the costs of such test
including any labor and transportation costs pertaining thereto. If the Measurement Facilities tested are found to be outside the range of accuracy set forth in Section 10.3(b), then the Party that owns such Measurement Facilities shall pay
such costs and perform the corrections according to Section 10.5.

 Section 10.5    Metered
Flow Rates in Error. If, for any reason, any Measurement Facilities are (i) out of adjustment, (ii) out of service or (iii) out of repair and the total calculated flow rate through each meter is found to be in error by an amount
of the magnitude described in Section 10.3, the total quantity of Crude Oil delivered shall be determined in accordance with the first of the following methods which is feasible: 

(a)    by using the registration of any mutually agreeable check metering facility, if installed and accurately
registering (subject to testing as provided for in Section 10.3); 
 (b)    where multiple
meters exist in series, by calculation using the registration of such meter equipment; provided that they are measuring Crude Oil from upstream and downstream headers in common with the faulty metering equipment, are not controlled by
separate regulators and are accurately registering; 
 (c)    by correcting the error by
re-reading of the official meter, or by straightforward application of a meter factor to the quantities recorded for the period (if the net percentage of error is ascertainable by calibration, tests or
mathematical calculation); or 
 (d)    by estimating the quantity, based upon deliveries made during periods of similar
conditions when the meter was registering accurately. 
 Section 10.6    Record
Retention. The Party owning the Measurement Facilities shall retain and preserve all test data, meter recordings and similar records for any calendar year for a period of at least 24 months following the end of such calendar year unless
Applicable Law requires a longer time period or the Party has received written notification of a dispute involving such records, in which case records shall be retained until the related issue is resolved.

supporting documentation that is not available on such twentieth Business Day as soon as it becomes available). Shipper shall make payment to Gatherer by the later of: (a) the last Business Day of the Month in which such invoice is received or
(b) 30 Days after receipt of the invoice. Such payment shall be made by wire transfer pursuant to wire transfer instructions delivered by Gatherer to Shipper in writing from time to time or other means as mutually agreeable by the Parties. If any

determination thereof; provided, however, that no retroactive adjustment will be made beyond a period of 24 Months from the date of a statement hereunder. 

Section 12.2    Right to Suspend on Failure to Pay. If any undisputed amount due
hereunder remains unpaid for 60 Days after the due date, Gatherer shall have the right to suspend or discontinue the Services hereunder until any such past due amount is paid.

to the other, shall have the right, at its expense, at reasonable times during normal business hours, but in no event more than twice in any period of 12 consecutive Months, to audit the books and records of the other to the extent necessary to
verify the accuracy of any statement, allocation, measurement, computation, charge, payment made under, or obligation or right pursuant to this Agreement. The scope of any audit shall be limited to transactions affecting Crude Oil tendered by or on
account of Shipper hereunder or the Services provided hereunder and shall be limited to the 24 Month period immediately prior to the Month in which the notice requesting an audit was given. All statements, allocations, measurements, computations,
charges or payments made in any period prior to the 24 Month period immediately prior to the Month in which the audit is requested shall be conclusively deemed true and correct and shall be final for all purposes. 

Section 12.4    Payment Disputes. In the event of any dispute with respect to any payment
hereunder, Shipper shall make timely payment of all undisputed amounts, and Gatherer and Shipper will use good faith efforts to resolve the disputed amounts within 60 Days following the original due date. Any amounts subsequently resolved shall be

 (b)    a Party is the subject of an involuntary
petition of bankruptcy under any chapter of the United States Bankruptcy Code, and such involuntary petition has not been settled or otherwise dismissed within 90 Days of such filing; or 

(c)    a Party otherwise becomes insolvent, whether by an inability to meet its debts as they come due in the ordinary
course of business or because its liabilities exceed its assets on a balance sheet test; and/or however such insolvency may otherwise be evidenced. 

ARTICLE 13 
 FORCE
MAJEURE 
 Section 13.1    Suspension of Obligations. In the event a Party is
rendered unable, wholly or in part, by Force Majeure to carry out its obligations under this Agreement, other than the obligation to make payments then or thereafter due hereunder, and such Party promptly gives notice and reasonably full particulars
of such Force Majeure in writing to the other Parties promptly after the occurrence of the cause relied on, then the obligations of the Party giving such notice, so far as and to the extent that they are affected by such Force Majeure, shall be
suspended during the continuance of any inability so caused, but for no longer period, and such cause shall so far as reasonably possible be remedied with all reasonable dispatch by the Party claiming Force Majeure. 

Section 13.2    Definition of Force Majeure. The term “Force
Majeure” as used in this Agreement shall mean any cause or causes not reasonably within the control of the Party claiming relief and which, by the exercise of reasonable diligence, such Party is unable to prevent or overcome, including
acts of God; strikes, lockouts or other industrial disturbances; acts of the public enemy, acts of terror, sabotage, wars, blockades, military action, insurrections or riots; epidemics; landslides, subsidence, lightning, earthquakes, fires, storms
or storm warnings; crevasses, floods or washouts; civil disturbances; explosions, breakage or accident to wells, machinery, equipment or lines of pipe; the necessity for testing or making repairs or alterations to wells, machinery, equipment or
lines of pipe; freezing of wells, equipment or lines of pipe; inability of any Party hereto to obtain, after the exercise of reasonable diligence, necessary materials, supplies, rights of way or Permits; or any action or restraint by any
Governmental Authority (so long as the Party claiming relief has not applied for or assisted in the application for, and has opposed where and to the extent reasonable, such action or restraint, and as long as such action or restraint is not the
result of a failure by the claiming Party to comply with Applicable Law). 

Section 13.3    Settlement of Strikes and Lockouts. It is understood and agreed that the
settlement of strikes or lockouts shall be entirely within the discretion of the Party affected thereby, and that the above requirement that any Force Majeure shall be remedied with all reasonable dispatch shall not require the settlement of strikes
or lockouts by acceding to the demands of the opposing party when such course is inadvisable in the sole discretion of the Party affected thereby. 

Section 13.4    Payments for Services Performed. Notwithstanding the foregoing, it is
specifically understood and agreed by the Parties that an event of Force Majeure will in no way affect or terminate Shipper’s obligation to make payment for the Services performed prior to such event of Force Majeure.

More particularly shown on Plat marked Exhibit “A”, and by this reference made a part hereof. 

In addition to the ROW described above, during any period of time that Grantee is installing or maintaining the Pipelines, Owner does HEREBY
GRANT, BARGAIN, SELL, CONVEY AND WARRANT unto Grantee a temporary easement of Seventy-Five feet (75’) in width, except that such easement shall be to a width of One Hundred feet (100’) at all road, ditch, and waterway crossings and any
areas of severely uneven ground.

for restricted rights of ingress and egress to, from and along said pipeline(s) and facilities of Grantee on, over and across said lands and adjacent lands of Owner, and Grantee shall have all privileges necessary or convenient for the full use and
enjoyment of the rights herein granted. 
 2.    Grantee may record this Right of Way Agreement attaching a plat as Exhibit
“A” (incorporated herein by reference) of the actual route of the facilities constructed hereunder and/or of the ingress/egress easement to further identify the locations thereof. 

3.    Grantee shall bury the top of its pipelines at or below Four feet (4’) in depth. Grantee shall restore the land as soon as
practicable after the pipelines are completed. Restoration shall be made as near as practicable to the condition when Grantee first entered onto the land. Grantee’s agreement to bury all pipelines shall in no way restrict Grantee from
installing above ground appurtenant facilities (markers, risers, headers, block valves, monitors, cathodic protection equipment, electrical power lines, etc.) necessary for the operations of said pipelines; however Grantee agrees to reasonably
attempt to locate said appurtenant facilities so as to minimize the impact of same to Owner’s use of the land covered herein.

of way that will interfere with rights and interests of Grantee herein granted, and provided further that Grantee shall have the right hereafter to keep clear obstructions from the herein granted right of way and ingress/egress easement. Grantee
agrees to pay Owner or any tenant, as their interest may appear, for actual damages to crops, pasture, timber, livestock, fences and other improvements on said premises which may arise from exercise of the rights herein granted, provided Grantee

wells, production facilities and/or compressor stations. This additional grant includes the pipelines needed to transport oil, gas, fresh water, production water, kindred substances and vapors. Owner will be paid for the additional lateral right of
ways and perpetual easements based on the same terms agreed upon in the Payment Agreement of even date herewith. Grantee will have the right to amend this Right of Way and Easement Agreement by filing an amendment, executed solely by Grantee, with

below regarding that certain Right of Way and Easement Agreement from Owner to Grantee (“ROW Agreement”) covering the following described lands located in
                     County, North Dakota:

 Grantor acknowledges
receipt of $500.00 as a down payment. The pipeline payment of $             per rod is to be paid per pipeline for up to four (4) pipelines. The down payment will be
deducted from the calculation of the total payment. The balance of the consideration due, if any, will be paid within thirty (30) days of the completion of a final survey of the pipelines as installed. In the event it is necessary to place an
additional line or lines, not to exceed four (4) lines, in a new lateral Right of Way, then Grantee agrees to pay Owner $             per rod for the placement of each
additional pipeline that is placed in the lateral Right of Way. 
 Grantee agrees to pay, in addition to the aforementioned payment, either (i) One
Thousand Dollars and no/100 ($1,000.00) per mile, or (ii) the established yield as determined by the Farm Service Agency office per mile of growing or planted crops, or hay land, where applicable, within the right of way under the ROW Agreement
which were destroyed as a direct result of the initial construction and installation of the Facilities. 
 If said Grantor owns less interest in the above
described land than the entire and undivided fee simple estate therein, then the payments herein provided for shall be paid the said Grantor only in the proportion which Grantor’s interest bears to the whole and undivided fee. 

It is expressly understood and agreed that the above specified payment for the ROW Agreement is contingent upon construction.

AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH BRACKETS AND THREE ASTERISKS [***] 

 
 Producer that is applicable as of the date of acquisition thereof to any Dedicated
Property acquired after the Effective Date (but not any Conflicting Dedication entered into in connection with such acquisition); provided, however, that Producer shall have the right to comply with Conflicting Dedications only until
the last Day of the Month in which the termination of such Conflicting Dedication occurs and Producer shall not affirmatively extend the term of such Conflicting Dedication beyond the minimum term provided for in the document evidencing such
Conflicting Dedication or allow the term of such Conflicting Dedications to extend beyond its primary or initial term pursuant to the operation of an “evergreen” or other similar provision if Producer has the ability to terminate such
Conflicting Dedication without incurring any costs, penalties or expenses. To Producer’s knowledge, the Dedicated Saltwater is not, as of the Effective Date, subject to any Conflicting Dedication. If Dedicated Saltwater produced from a Well on
a Well Pad is subject to a Conflicting Dedication that Producer has the right to comply with under this Section 2.2, Producer has the right, in complying with such Conflicting Dedication, to deliver all Dedicated Saltwater from such Well
Pad in accordance with the Conflicting Dedication. 
 Section 2.3 Producer’s Reservations. Producer
reserves the following rights with respect to Dedicated Saltwater for itself and for the operator of the relevant Dedicated Properties: (a) to operate Wells producing oil, gas and Dedicated Saltwater as a reasonable and prudent operator in its
sole discretion, including the right, but never the obligation, to drill New Wells, to repair and rework then-existing Wells, to renew or extend, in whole or in part, any Interest covering any of the Dedicated Properties, and to cease production
from or abandon any Well or surrender or release any such Interest, in whole or in part, whether or not capable of producing oil and gas and Saltwater under normal methods of operation; (b) to deliver Dedicated Saltwater that has been
temporarily or permanently released from the dedication and commitment made by Producer under this Agreement, including pursuant to Section 3.3(b), Section 3.4(c), Section 6.4(a), Section 6.5 or Section
8.2(d), to any Person other than Gatherer; (c) to separate, process or otherwise remove any constituents, contaminants or skim oil in the Dedicated Saltwater prior to delivery to Gatherer at the Receipt Points; and (d) to acquire Wells
connected to existing gathering systems and to continue to deliver to such gathering systems Saltwater produced from such Wells; provided that, to the extent that Saltwater from such Wells constitutes Dedicated Saltwater and Saltwater from
such Wells is not previously dedicated to a third party, then Producer shall deliver a Connection Notice to Gatherer with respect to any such Well not later than 30 Days after its acquisition, and thereafter shall deliver Saltwater to such gathering
system only until Gatherer has connected such Well to the Gathering System in accordance with Section 3.3. 

Section 2.4 Covenant Running with the Land. The Parties intend that the dedication and commitment made by
Producer under this Agreement be a covenant running with (a) the Dedicated Properties, as a burden on Producer’s title thereto and binding on
successors-in-interest in and to the Dedicated Properties, and (b) the Disposal System, as a benefit accruing to Gatherer’s title thereto and inuring to the
benefit of successors-in-interest to the Disposal System. Producer shall not Transfer any or all of its interest in any Dedicated Property unless (i) Producer
obtains and delivers to Gatherer a written acknowledgment by the Transferee in favor of Gatherer acknowledging that the Transferred Dedicated Property shall remain subject to this Agreement in all respects and (ii) each instrument of conveyance
expressly so states. Notwithstanding the foregoing, Producer shall be permitted to Transfer any Dedicated Property

 free of the dedication and commitment made by Producer under this Agreement and without
complying with the requirements of this Section 2.4 in a Transfer in which a number of net acres of Dedicated Properties that, when added to the total of net acres of Dedicated Properties theretofore and, where applicable, simultaneously
Transferred free and clear of the dedication and commitment made by Producer under this Agreement, does not exceed the aggregate number of net acres of Dedicated Properties acquired by Producer after the Effective Date, including in a transaction in
which Dedicated Properties are exchanged for other properties located in the Dedicated Acreage that would be subject to dedication hereunder; provided, however, that any such release of Dedicated Properties from such dedication and
commitment shall not include any Dedicated Saltwater produced from any Well that is located on a Well Pad if the other Wells on such Well Pad are or have been connected to the Gathering System (whether producing,
shut-in, temporarily abandoned or which has been spud or as to which drilling, completion, reworking or other well operations have commenced) or that is located on a Well Pad if a Connection Notice has
previously been delivered by Producer for the CDP through which such Well Pad is produced. 
 Section 2.5
Priority of Dedicated Saltwater. Dedicated Saltwater tendered at the Receipt Points on the Gathering System on any Day shall be Firm Capacity Saltwater. Producer’s Saltwater that is not Dedicated Saltwater that is tendered at the
Receipt Points on any Day shall be Interruptible Saltwater unless otherwise agreed to by Gatherer.

AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH BRACKETS AND THREE ASTERISKS [***] 

 
 (f) provide, maintain and operate adequate pumps and equipment to create
sufficient pressure in the Disposal System to transfer all Saltwater up to the Maximum DSU Volume per Day received into the Gathering System from Producer at the Receipt Points and to dispose of all such Saltwater into the Disposal Wells; 

(g) dispose of all Saltwater received into the Gathering System or picked up by truck in accordance with this Agreement into the Disposal
Wells; and 
 (h) upon request of Producer, gather and dispose of Excluded Water, if Gatherer agrees to do so in its sole discretion. 

Gatherer shall act as a Reasonable and Prudent Operator in performing the Services and any of its other obligations under this Agreement. 

Section 3.2 Exchange and Review of Information. 

(a) The Parties recognize that all information provided by Producer to Gatherer regarding its intentions with respect to the development of
the Dedicated Properties is subject to change and revision at any time at the discretion of Producer, and that such changes may impact the timing, configuration and scope of the planned activities of Gatherer. The exchange of such information and
any changes thereto shall not give rise to any rights or liabilities as among the Parties except as expressly set forth in this Agreement, and Gatherer shall determine at its own risk the time at which it begins to work on and incur costs in
connection with particular Gathering System expansion projects, including the acquisition of rights of way, equipment and materials. Without limiting the generality of the foregoing, Producer has no obligation to Gatherer under this Agreement to
develop or produce any Saltwater from the Dedicated Properties or to pursue or complete any drilling or development on the Dedicated Properties other than the terms specifically stated in this Agreement. 

(b) Producer agrees to provide to Gatherer, prior to October 15 of each year, copies of a drilling plan for the following calendar year,
which shall describe the planned drilling and production activities relating to Producer’s Interests in the Dedicated Acreage during such year, including good faith and reasonable forecasts of the volume of Dedicated Saltwater expected to be
produced through all CDPs during such year, and including the location of all Planned CDPs expected to be connected to the Gathering System during such year, and the projected spud date, projected completion date and projected volumes for each New
Well that is expected to be completed and to produce through each CDP during such year. Each time Producer materially updates such drilling plan, it shall provide a copy of such updated drilling plan to Gatherer, but not less frequently than on a
calendar quarter basis. 
 Section 3.3 CDP Connections. 

(a) Gatherer shall design and develop the Disposal System for the purpose of providing the Services as and when needed to support the upstream
development of the Dedicated Acreage, and Gatherer shall be obligated, at its sole cost and expense, subject to the provisions of this Agreement, to procure, construct, install, own and operate the Disposal System so as to timely connect the Planned
CDPs to the Gathering System, connect the Gathering System to Disposal Wells and timely commence providing the full scope of the Services with

 REQUESTED. THE REDACTED MATERIAL HAS BEEN SEPARATELY FILED WITH THE SECURITIES AND EXCHANGE COMMISSION, 

AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH BRACKETS AND THREE ASTERISKS [***] 

 
 respect to all Dedicated Saltwater produced from all CDPs, including the Planned CDPs
from and after their connection to the Gathering System, all in accordance with this Section 3.3; provided that the foregoing shall not preclude Gatherer from also designing and developing the Gathering System to accommodate Third
Party Saltwater. 
 (b) Producer shall from time to time give notice (a “Connection Notice”) to Gatherer of each CDP
that Producer intends to construct and install (or a CDP that is subject to a Conflicting Dedication that has expired or will expire, or that Producer has terminated or will terminate, prior to the applicable Completion Deadline) through which
Dedicated Saltwater will be produced (each, a “Planned CDP”). Each Connection Notice shall set forth the target completion date for drilling and completion of the initial Well to produce through such Planned CDP (the
“Target Completion Date”). Following delivery of a Connection Notice with respect to a Planned CDP, Gatherer shall cause the necessary facilities to be constructed to connect such Planned CDP to the Gathering System and to
commence the Services with respect to Dedicated Saltwater produced from such Planned CDP by the date that is (i) in the case of a Planned CDP that (A) is located two miles or less from the then-existing Gathering System at the time of such
Connection Notice and (B) the Target Completion Date for which is during the months of May through October, 90 Days after the date of Producer’s delivery of such Connection Notice and (ii) in the case of a Planned CDP that is
(A) located greater than two miles from the then-existing Gathering System at the time of such Connection Notice or (B) the Target Completion Date for which is during the months of November through April, 180 Days after the date of
Producer’s delivery of such Connection Notice (such date, the “Completion Deadline”). Gatherer shall provide Producer notice promptly upon Gatherer’s becoming aware of any reason to believe that it may not be able
to connect a Planned CDP to the Gathering System by the Completion Deadline therefor or to otherwise complete all facilities necessary to provide the full scope of the Services with respect to all Dedicated Saltwater produced through such Planned
CDP by the Completion Deadline therefor. If and to the extent Gatherer is delayed in completing and making available such facilities by a Force Majeure event or any action of Producer that is inconsistent with the cooperation requirements of
Section 3.5, then the Completion Deadline for such connection shall be extended for a period of time equal to that during which Gatherer’s completion and making available of such facilities was delayed by such events or actions. If
such facilities are not completed and made available by the Completion Deadline (as may be extended in accordance with Section 3.4(b)), as Producer’s sole and exclusive remedies for such delay: 

(i) Gatherer shall truck the Dedicated Saltwater produced through such CDP in accordance with Section 6.4 at
Gatherer’s sole cost and expense from the Completion Deadline (but without giving any effect to any extension of the Completion Deadline as a result of Force Majeure) until the Gathering System is connected to such CDP; and 

(ii) at Producer’s option, the Dedicated Saltwater produced from the CDP and any future Wells drilled within the same DSU
or any portion thereof shall be permanently released from the dedication and commitment made by Producer under this Agreement.

AND THE TERMS HAVE BEEN MARKED AT THE APPROPRIATE PLACE WITH BRACKETS AND THREE ASTERISKS [***] 

 
 (c) To the extent that the CDP connection is required sooner than the
Completion Deadline determined as set forth above, the Parties shall meet and discuss the issues and potential additional costs associated with acceleration of such connection, and shall use reasonable efforts mutually to agree upon an accelerated
connection timing. If Producer is willing to pay for the additional costs involved with accelerating a connection, Gatherer shall use reasonable efforts to complete the CDP connection within such accelerated timing. 

Section 3.4 Right of Way and Access. 

(a) Gatherer is responsible for the acquisition of rights of way, crossing permits, licenses, use agreements, access agreements, leases, fee
parcels and other rights in land necessary to construct, own and operate the Gathering System, and all such rights in land shall be solely for use by Gatherer and shall not be shared with Producer, except as otherwise agreed by Gatherer;
provided that Producer agrees to grant, without warranty of title, either express or implied, to the extent that it has the right to do so without the incurrence of expense, an easement and right of way upon the lands covered by the Dedicated
Properties, for the sole purpose of installing, using, maintaining, servicing, inspecting, repairing, operating, replacing, disconnecting and removing all or any portion of the Gathering System, including any pipelines, meters and other equipment
necessary for the performance of this Agreement; provided, further, that the exercise of these rights by Gatherer shall not unreasonably interfere with Producer’s lease operations or with the rights of owners in fee, and will be
subject to Producer’s safety and other reasonable access requirements applicable to Producer’s personnel. Producer shall not have a duty to maintain the underlying agreements (such as leases, easements and surface use agreements) that such
grant of easement or right of way to Gatherer is based upon, and such grants of easement or right of way will terminate if Producer loses its rights to the property, regardless of the reason for such loss of rights. Notwithstanding the foregoing,
(i) Producer will assist Gatherer to secure replacements for such terminated grants of easement or right of way, in a manner consistent with the cooperation requirements of Section 3.5, (ii) to the extent that Producer agrees that
Gatherer’s Measurement Facilities may be located on Producer’s Well Pad sites, Producer shall be responsible for obtaining any necessary rights to locate such Measurement Facilities on such Well Pad sites and (iii) Producer shall use
reasonable efforts to involve Gatherer in Producer’s negotiations with the owners of lands covered by the Dedicated Properties so that Producer’s surface use agreements and Gatherer’s rights of way with respect to such lands can be
concurrently negotiated and obtained. 
 (b) If Gatherer cannot obtain the rights of way (on terms and conditions reasonably acceptable to
Gatherer after diligent pursuit thereof) necessary to connect any Planned CDP within 45 Days of delivery of a Connection Notice, then Gatherer shall so notify Producer in writing (the “Easement Notice”) within 45 Days of
delivery of the Connection Notice. Producer shall have the right (but not the obligation) to obtain, at its sole cost and expense, such rights of way generally in the format of Gatherer’s standard right of way agreement within 45 Days of
delivery of such Easement Notice. Gatherer’s form of right of way agreement is attached as Exhibit C. The right of way agreement utilized by Producer can have modifications to the Exhibit C format as long as it does not materially
change or reduce the rights or obligations under such right of way agreement. If Producer obtains such rights of way in accordance with the immediately preceding sentence, Producer shall assign such right of way to Gatherer, and Gatherer’s
connection obligations for the applicable CDP shall continue in

 accordance with the terms of this Agreement; provided, however, that the
time required for Gatherer to connect the applicable CDP shall be extended by a number of days commencing on the date of delivery of the Easement Notice and ending on the date that Gatherer receives from Producer the assignment of all such rights of
way so obtained by Producer (together with executed originals of all such rights of way). In such event, Gatherer shall pay Producer for such rights of way an amount per rod equal to the average price per rod paid by Gatherer for the purchase of
rights of way in the Dedicated Acreage during the preceding 12 month period. If Gatherer has not purchased right of way within the Dedicated Acreage during the previous 12 months, then Gatherer shall pay Producer for such rights of way an amount per
rod equal to the amount per rod paid by Gatherer under its most recent purchase of rights of way in the Dedicated Acreage. 
 (c) In the
event that Producer fails to obtain such rights of way during such 45 Day period, Gatherer shall be responsible for trucking Saltwater from such Planned CDP to a Disposal Well subject to and in accordance with Section 6.4, and Producer
shall have the option, upon written notice to Gatherer, to permanently release the entire DSU or any portion thereof associated with the Wells connected to such CDP from the dedication and commitment made by Producer under this Agreement. 

Section 3.5 Cooperation. Because of the interrelated nature of the actions of Producer and Gatherer required
to obtain the necessary Permits from the appropriate Governmental Authorities and the necessary consents, rights of way and other authorizations from other Persons necessary to drill and complete each Well and construct the required extensions of
the Gathering System to each Planned CDP, Producer and Gatherer agree to work together in good faith to obtain such Permits, authorizations, consents and rights of way as expeditiously as reasonably practicable. Producer and Gatherer further agree
to cooperate with each other and to communicate regularly regarding their efforts to obtain such Permits, authorizations, consents and rights of way. 

Section 3.6 Allocation of Gatherer Obligations. 

(a) OMS and MLP shall be jointly and severally liable for obligations of Gatherer under this Agreement; provided that (i) (A) OMS
shall be severally, and not jointly, liable for the obligations of Gatherer to expand or add additional capacity to the Disposal System, and in the case of any such expansion or addition, OMS’s liability shall be limited to a percentage of such
liability equal to its percentage ownership interest (but not including any of OMS’s indirect ownership interest through MLP), at the time such liability is incurred, in the DevCo that owns or will own such expansion or addition (which
percentage may be zero) and (B) OMS shall not have any liability for the obligations of Gatherer that are solely related to assets owned by, or Services performed by, a DevCo or DevCos in which OMS does not hold any ownership interest (other
than an indirect ownership interest through MLP) at the time the applicable obligation arose and (ii) (A) MLP shall be severally, and not jointly, liable for the obligations of Gatherer to expand or add additional capacity to the Disposal
System, and in the case of any such expansion or addition, MLP’s liability shall be limited to a percentage of such liability equal to its percentage ownership interest, at the time such liability is incurred, in the DevCo that owns or will own
such expansion or addition (which percentage may be zero) and (B) MLP shall not have any liability for the obligations of Gatherer that are solely related to assets owned by, or Services performed by, a DevCo or DevCos in which MLP does not
hold any ownership interest at the time the applicable obligation arose.

Barrels received at the Receipt Points on the Gathering System on such DSU on such Day. For all volumes of Saltwater picked up by Gatherer by truck in accordance with this Section 6.4(a), Gatherer shall be entitled to receive the sum of
(1) the actual third party invoiced cost for trucking such Saltwater not to exceed the Gathering Fee and (2) the Disposal Fee. Gatherer shall use reasonable efforts to minimize trucking costs by bidding out the required trucking services
on an annual basis or more frequently as requested by Producer, but not to exceed two times per Contract Year. Gatherer shall provide the results of each such bid process to Producer. Within 30 Days of commencing trucking operations pursuant to this
Section 6.4(a), Gatherer shall provide Producer with a written explanation detailing the reason for its inability to receive volumes into the Gathering System, and its commitment to diligently pursue a plan to achieve delivery of all volumes
of Saltwater tendered by Producer up to the Maximum DSU Volume for any DSU through the Gathering System at each affected DSU. The Parties may mutually agree to review capacity in excess of the Maximum DSU Volume for any DSU. Notwithstanding the
foregoing, in no event shall Gatherer be required to provide trucking services pursuant to this Section 6.4(a) for a period in excess of [***] consecutive months per DSU; provided that if Gatherer is not able to receive volumes up to
the Maximum DSU Volume at the Receipt Points on each DSU on any Day for any reason other than Force Majeure and, as a result, Producer has excess volume that is being curtailed on the Gathering System for a period in excess of [***] months, then
Gatherer shall (at Producer’s request and option) either (A) permanently release the entire DSU or any portion thereof associated with the Wells connected to such CDP from the dedication and commitment made by Producer under this Agreement
or (B) continue to truck excess volumes up to the Maximum DSU Volume beyond the aforementioned [***] month period and receive the Fees for such volumes. 

(b) For volumes of Saltwater that Gatherer is unable to receive into the Gathering System for any reason that Gatherer is not obligated to
pick up by truck pursuant to Section 6.4(a), Gatherer shall, if requested by Producer, truck such volumes and charge actual third party invoiced costs to Producer for such trucking in lieu of the Gathering Fee (but Gatherer shall continue to
receive the applicable Disposal Fee for all such Saltwater). For the avoidance of doubt, such actual third party invoiced costs to truck shall not be limited to the Gathering Fee. 

Section 6.5 Temporary Releases. In addition to any other rights and remedies available to Producer under this
Agreement or at law or in equity, if Gatherer fails or is unable or unwilling for any reason (including Force Majeure) to accept all volumes of Dedicated Saltwater tendered by or on behalf of Producer pursuant to this Agreement and provide the
Services in accordance therewith, including any failure or inability to truck volumes of Saltwater in accordance with Section 6.4, then the volumes of Dedicated Saltwater in excess of what Gatherer is willing and able to accept shall be
temporarily released from the dedication and commitment made by Producer under this Agreement. Producer may immediately deliver such volumes to any Person other than Gatherer, and Producer shall have the right to enter into commitments to deliver
such volumes of Dedicated Saltwater to other third party gatherers, such commitments to be for no longer than reasonably necessary under the circumstances, as determined by Producer in its sole discretion.

PRESSURES; PRODUCER’S FACILITIES; ELECTRICITY 

Section 7.1 Pressures at Receipt Points. Producer shall deliver or cause to be delivered Saltwater to each
Receipt Point on the Gathering System from atmospheric tanks or from low pressure separation at sufficient pressure to enter Gatherer’s Receipt Point pump on the Gathering System against its operating pressure, except that Gatherer shall not be
obligated to gather Saltwater at pressures in excess of the maximum allowable operating pressure of the Gathering System at such Receipt Point, as determined by Gatherer in its sole discretion. Gatherer shall operate its measurement and Receipt
Point pump at a pressure that allows Producer to deliver Saltwater directly from its atmospheric tanks or low pressure separation into the Gathering System without additional pumps; provided that such atmospheric tanks have a minimum of four
feet of hydrostatic head or low pressure separation at the low liquid level to allow Gatherer’s pumps to attain proper suction pressure. 

Section 7.2 Producer Facilities. 

(a) Producer, at its own expense, shall construct, equip, maintain and operate all facilities necessary to deliver Dedicated Saltwater to
Gatherer at the Receipt Points. Producer shall install and maintain sufficient pressure regulating equipment upstream of the Receipt Points on the Gathering System in order to keep the pressure of the Saltwater delivered to Gatherer at such Receipt
Points from exceeding the maximum allowable operating pressure of the Gathering System at the applicable Receipt Point, as determined by Gatherer in its sole discretion. Such equipment shall include low pressure separation facilities and atmospheric
tankage upstream of the Receipt Points. 
 (b) Producer shall have the right to install facilities and flow volumes attributable to
Producer’s interests in operated and non-operated wells outside, but on DSUs that are contiguous with, the Dedicated Acreage, allowing such wells to flow into existing CDPs or to new CDPs mutually agreed
between Producer and Gatherer where Gatherer shall provide a meter and tap at Gatherer’s sole cost and expense. Producer shall provide a list of wells from outside, but on DSUs that are contiguous with, the Dedicated Acreage that will be
connected to existing CDPs or to new CDPs in accordance with this Section 7.2(b). 
 Section 7.3
Electrical Facilities. To the extent that Producer has electrical power available at a CDP in excess of Producer’s own uses, as Producer determines in its reasonable discretion, Producer will supply electrical power without cost to
Gatherer at each such CDP for Gatherer’s Measurement Facilities and pumps. If Gatherer requires additional electrical power at such site, then Gatherer shall either install, own, operate and maintain a generator at its sole cost and expense or
shall truck such volumes from such CDP at its sole cost and expense subject to and in accordance with Section 6.4.

QUALITY 

Section 8.1 Receipt Point Saltwater Quality Specifications. Saltwater delivered by Producer to each Receipt
Point shall meet the following specifications (collectively, the “Saltwater Quality Specifications”): 
 (a)
temperature of not more than [***] degrees Fahrenheit at the Receipt Point; 
 (b) total suspended solids of not more than [***] percent;
and 
 (c) free of hazardous wastes and other substances that may not be received into or transferred through the Gathering System,
transported by truck or disposed of into the Disposal Wells in accordance with Applicable Laws and Permits and Gatherer’s operational standards. 

Section 8.2 Non-Spec Saltwater. 

(a) Gatherer shall test and monitor the Saltwater tendered by Producer at the Receipt Points as a Reasonable and Prudent Operator to ensure
that it meets the Saltwater Quality Specifications. If Gatherer determines at any time that any Saltwater tendered by Producer at any Receipt Point does not meet the Saltwater Quality Specifications, then Gatherer shall have the right, at its sole
option and effective immediately upon notice to Producer, to refuse to accept such Saltwater. 
 (b) If Producer determines or otherwise
becomes aware at any time prior to delivery that any Saltwater that will be tendered by Producer at any Receipt Point will not meet the Saltwater Quality Specifications, then Producer shall provide written notice to Gatherer. Upon receipt of such
notice, if Gatherer nevertheless accepts such Saltwater, then Producer shall not be liable for any claims or losses arising out of or related to delivery of such Saltwater, including any damages or losses downstream of the applicable Receipt
Point(s). 
 (c) Producer shall not be liable for any claims or losses arising out of or related to delivery of Saltwater that does not meet
the Saltwater Quality Specifications, including any damages or losses downstream of the applicable Receipt Point(s); provided that Producer shall be liable for such claims or losses if Producer determines or otherwise becomes aware at any
time prior to delivery that any Saltwater that will be tendered by Producer at any Receipt Point will not meet the Saltwater Quality Specifications and Producer fails to deliver written notice to Gatherer pursuant to Section 8.2(b). 

(d) Any Saltwater that is tendered by Producer that Gatherer refuses to accept pursuant to this Section 8.2 shall be temporarily
released from the dedication and commitment made by Producer under this Agreement so that Producer may dispose of any such Saltwater.

MEASUREMENT EQUIPMENT AND PROCEDURES 

Section 9.1 Measurement Facilities. Gatherer shall install, own, operate and maintain Measurement Facilities
to measure Saltwater at all the Receipt Points located on the Gathering System. Measurement Facilities at such Receipt Points shall meet current industry standards for custody transfer measurement. Producer shall have the right to install check
Measurement Facilities upstream of each such Receipt Point. 
 Section 9.2 Notice of Measurement Facilities
Inspection and Calibration. Each of Producer and Gatherer shall give two days’ notice to the other in order that the other may, at its option, have representatives present to observe any reading, inspecting, testing, calibrating or
adjusting of Measurement Facilities used in measuring or checking the measurement of receipts of Saltwater under this Agreement. The data from such Measurement Facilities shall remain the property of the Measurement Facilities’ owner, but
copies of such records shall, upon written request, be submitted to the requesting Party for inspection and verification. 

Section 9.3 Measurement Accuracy Verification. 

(a) Gatherer shall calibrate meters as often as required, as determined by Gatherer in accordance with standard industry practices to
reasonably assure accurate measurement, but at least once per year. 
 (b) If, during any test of the Measuring Facilities, an adjustment or
calibration error is found which results in an incremental adjustment to the calculated flow rate through each meter in excess of two percent of the adjusted flow rate (whether positive or negative and using the adjusted flow rate as the percent
error equation denominator), then any previous recordings of such equipment shall be corrected to zero error for any period during which the error existed (and which is either known definitely or agreed to by Producer and Gatherer) and the total
flow for the period redetermined in accordance with the provisions of Section 9.5. If the period of error condition cannot be determined or agreed upon between Producer and Gatherer, such correction shall be made over a period extending
over the last one half of the time elapsed since the date of the prior test revealing the two percent error. 
 (c) If, during any test of
any Measurement Facilities, an adjustment or calibration error is found which results in an incremental adjustment to the calculated flow rate which does not exceed two percent of the adjusted flow rate, all prior recordings and data shall be
considered to be accurate for quantity determination purpose. 
 Section 9.4 Special Tests. If Producer or
Gatherer desires a test of any Measurement Facilities not scheduled by a Party under the provisions of Section 9.3, two days advance notice shall be given to the other and both Producer and Gatherer shall cooperate to secure a prompt
test of the accuracy of such equipment. If the Measurement Facilities tested are found to be within the range of accuracy set forth in Section 9.3(b), then the Party that requested the test shall pay the costs of such test including any labor
and transportation costs pertaining thereto. If the Measurement Facilities tested are found to be outside the range of accuracy set forth in Section 9.3(b), then the Party that owns such Measurement Facilities shall pay such costs and perform
the corrections according to Section 9.5.

 Section 9.5 Metered Flow Rates in
Error. If, for any reason, any Measurement Facilities are (i) out of adjustment, (ii) out of service or (iii) out of repair and the total calculated flow rate through each meter is found to be in error by an amount of the
magnitude described in Section 9.3, the total quantity of Saltwater delivered shall be determined in accordance with the first of the following methods which is feasible: 

(a) by using the registration of any mutually agreeable check metering facility, if installed and accurately registering (subject to testing as
provided for in Section 9.3); 
 (b) where multiple meters exist in series, by calculation using the registration of such meter
equipment; provided that they are measuring Saltwater from upstream and downstream headers in common with the faulty metering equipment, are not controlled by separate regulators and are accurately registering; 

(c) by correcting the error by re-reading of the official meter, or by straightforward application of
a correcting factor to the quantities recorded for the period (if the net percentage of error is ascertainable by calibration, tests or mathematical calculation); or 

(d) by estimating the quantity, based upon deliveries made during periods of similar conditions when the meter was registering accurately.

 Section 9.6 Record Retention. The Party owning the Measurement Facilities shall retain and preserve all
test data, meter recordings and similar records for any calendar year for a period of at least 24 months following the end of such calendar year unless Applicable Law requires a longer time period or the Party has received written notification of a
dispute involving such records, in which case records shall be retained until the related issue is resolved. 

Section 9.7 Measurement of Saltwater Collected by Truck. Saltwater collected by truck shall be measured
either by the Measurement Facilities into which such Saltwater is delivered or by gauging the water level in Producer’s tanks into which such water is delivered or by such other method as shall be mutually agreed to by the Parties. 

Section 9.8 Summary Measurement Reports. If Gatherer develops summary measurement reports for Producer’s
Wells or the Gathering System, Gatherer shall provide copies of such reports to Producer upon Producer’s request.

 FORCE
MAJEURE 
 Section 12.1 Suspension of Obligations. In the event a Party is rendered unable, wholly or
in part, by Force Majeure to carry out its obligations under this Agreement, other than the obligation to make payments then or thereafter due hereunder, and such Party promptly gives notice and reasonably full particulars of such Force Majeure in
writing to the other Parties promptly after the occurrence of the cause relied on, then the obligations of the Party giving such notice, so far as and to the extent that they are affected by such Force Majeure, shall be suspended during the
continuance of any inability so caused, but for no longer period, and such cause shall so far as reasonably possible be remedied with all reasonable dispatch by the Party claiming Force Majeure. 

Section 12.2 Definition of Force Majeure. The term “Force Majeure” as used in this
Agreement shall mean any cause or causes not reasonably within the control of the Party claiming relief and which, by the exercise of reasonable diligence, such Party is unable to prevent or overcome, including acts of God; strikes, lockouts or

equipment or lines of pipe; inability of any Party hereto to obtain, after the exercise of reasonable diligence, necessary materials, supplies, rights of way or Permits; or any action or restraint by any Governmental Authority (so long as the Party
claiming relief has not applied for or assisted in the application for, and has opposed where and to the extent reasonable, such action or restraint, and as long as such action or restraint is not the result of a failure by the claiming Party to
comply with Applicable Law). 
 Section 12.3 Settlement of Strikes and Lockouts. It is understood and
agreed that the settlement of strikes or lockouts shall be entirely within the discretion of the Party affected thereby, and that the above requirement that any Force Majeure shall be remedied with all reasonable dispatch shall not require the
settlement of strikes or lockouts by acceding to the demands of the opposing party when such course is inadvisable in the sole discretion of the Party affected thereby. 

Section 12.4 Payments for Services Performed. Notwithstanding the foregoing, it is specifically understood
and agreed by the Parties that an event of Force Majeure will in no way affect or terminate Producer’s obligation to make payment for the Services performed prior to such event of Force Majeure.

“Grantee”) a perpetual and permanent right-of-way and easement (the “ROW”) of Fifty feet (50’) in width for the placement of up to four
(4) Pipelines (as defined herein). The ROW is granted for the purpose of laying, constructing, maintaining, operating, inspecting, repairing, replacing, protecting, changing the size of and removing pipelines and appurtenances thereto for the
transportation of oil, gas, fresh water, production water, kindred substances and vapors or the products thereof (the “Pipelines”) upon and along a route to be selected by Grantee in consultation with Owner on, under and across lands of
Owner, situated in the County of                 , State of                 ,
described as follows: 
 Township         
                    , Range         
                     
 Section
    :                      

More particularly shown on Plat marked Exhibit “A”, and by this reference made a part hereof. 

In addition to the ROW described above, during any period of time that Grantee is installing or maintaining the Pipelines, Owner does HEREBY
GRANT, BARGAIN, SELL, CONVEY AND WARRANT unto Grantee a temporary easement of Seventy-Five feet (75’) in width, except that such easement shall be to a width of One Hundred feet (100’) at all road, ditch, and waterway crossings and any
areas of severely uneven ground. 
 The aforesaid rights and the ROW are granted as and from the date hereof, and shall be perpetual, on the
following terms and conditions, which are hereby mutually agreed to by and between Owner and Grantee. 
 1. Together with an easement for restricted rights
of ingress and egress to, from and along said pipeline(s) and facilities of Grantee on, over and across said lands and adjacent lands of Owner, and Grantee shall have all privileges necessary or convenient for the full use and enjoyment of the
rights herein granted. 
 2. Grantee may record this Right of Way Agreement attaching a plat as Exhibit “A” (incorporated herein by reference) of
the actual route of the facilities constructed hereunder and/or of the ingress/egress easement to further identify the locations thereof. 
 3. Grantee
shall bury the top of its pipelines at or below Four feet (4’) in depth. Grantee shall restore the land as soon as practicable after the pipelines are completed. Restoration shall be made as near as practicable to the condition when Grantee
first entered onto the land. Grantee’s agreement to bury all pipelines shall in no way restrict Grantee from installing above ground appurtenant facilities (markers, risers, headers, block valves, monitors, cathodic protection equipment,
electrical power lines, etc.) necessary for the operations of said pipelines; however Grantee agrees to reasonably attempt to locate said appurtenant facilities so as to minimize the impact of same to Owner’s use of the land covered herein.

or any tenant, as their interest may appear, for actual damages to crops, pasture, timber, livestock, fences and other improvements on said premises which may arise from exercise of the rights herein granted, provided Grantee shall not be liable for
damages for future clearing of the right of way and ingress/egress easement in exercise of the rights herein granted. 
 5. Grantee shall be liable for
reclamation and damages resulting from a breach or spill. 
 6. Grantee agrees to comply with all applicable state and local regulations. 

7. This Agreement may be executed in several counterparts, each of which shall be an original of this Agreement but all of which, taken together, shall
constitute one and the same Agreement and be binding upon the parties who executed any counterpart, regardless of whether it is executed by all parties named herein. 

8. Owner agrees to grant additional lateral right of ways and perpetual easements that Grantee may need to connect to any well or wells, production facilities
and/or compressor stations. This additional grant includes the pipelines needed to transport oil, gas, fresh water, production water, kindred substances and vapors. Owner will be paid for the additional lateral right of ways and perpetual easements
based on the same terms agreed upon in the Payment Agreement of even date herewith. Grantee will have the right to amend this Right of Way and Easement Agreement by filing an amendment, executed solely by Grantee, with new plats showing the location
of the additional lateral right of ways and perpetual easements. 
 9. This instrument together with the Payment Agreement for Right of Way and Easement
dated                      constitutes the entire agreement and understanding of the parties and supersedes all prior understandings, negotiations
and agreements of the parties related to the subject matter hereof. Each party agrees to give the other a 30 day right to cure after notice of any default before seeking termination or exercising any other remedy. 

TO HAVE AND TO HOLD said right of way and easement unto said Grantee, its successors and assigns for so long as same are used for the purposes herein granted.
All provisions hereof are appurtenant to, run with and burden the above described land, and are binding upon and inure to the benefit of the successors, assigns, heirs, executors, administrators and other legal representatives of each of the
parties.

 PAYMENT AGREEMENT FOR RIGHT OF WAY AND EASEMENT AGREEMENT 

This agreement entered into this             day
of                    , 2017 between
                    , husband and wife whose address

In consideration of Twenty Five Dollars ($25.00) and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Owner hereby consents and agrees to the payment arrangement set out below regarding that certain
Right of Way and Easement Agreement from Owner to Grantee (“ROW Agreement”) covering the following described lands located in
                     County, North Dakota:

Section     :
                     
 Grantor acknowledges receipt of
$500.00 as a down payment. The pipeline payment of $             per rod is to be paid per pipeline for up to four (4) pipelines. The down payment will be deducted from
the calculation of the total payment. The balance of the consideration due, if any, will be paid within thirty (30) days of the completion of a final survey of the pipelines as installed. In the event it is necessary to place an additional line
or lines, not to exceed four (4) lines, in a new lateral Right of Way, then Grantee agrees to pay Owner $             per rod for the placement of each additional pipeline that
is placed in the lateral Right of Way. 
 Grantee agrees to pay, in addition to the aforementioned payment, either (i) One Thousand Dollars and no/100
($1,000.00) per mile, or (ii) the established yield as determined by the Farm Service Agency office per mile of growing or planted crops, or hay land, where applicable, within the right of way under the ROW Agreement which were destroyed as a
direct result of the initial construction and installation of the Facilities. 
 If said Grantor owns less interest in the above described land than the
entire and undivided fee simple estate therein, then the payments herein provided for shall be paid the said Grantor only in the proportion which Grantor’s interest bears to the whole and undivided fee. 

It is expressly understood and agreed that the above specified payment for the ROW Agreement is contingent upon construction.
