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

 

 Section 2.2    Conflicting Dedications. Producer 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 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(e), 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.

 ARTICLE 3

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

 

 (e)    receive, or cause to be received, into the Gathering System, from
Producer, at each Receipt Point, all Interruptible Saltwater, if any, to the extent not curtailed in accordance with Section 6.3; 

(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 Required Connection 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 Required Connection CDPs to the Gathering System, connect the Gathering System to Disposal Wells and timely commence providing the full scope of the Services with respect to all Dedicated Saltwater produced from all CDPs,
including the Required Connection 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”). 

(c)    On or before the 30th Day after Producer’s delivery of a
Connection Notice for a Planned CDP, Gatherer shall, by notice to Producer, (i) (A) acknowledge that the Planned CDP covered by such Connection Notice is a Required Connection CDP or (B) acknowledge that such Planned CDP is not a Required
Connection CDP but nonetheless commit to connect such Planned CDP to the Gathering System and perform the Services in respect of Dedicated Saltwater produced from such Well(s) to be connected to the Planned CDP for the Fees, or (ii) state that
it has determined that such Planned CDP is not a Required Connection CDP and state the fee that Gatherer would charge to Producer in lieu of the Gathering Fee for connecting such Planned CDP to the Gathering System and performing the Services in
respect of Dedicated Saltwater produced through such Planned CDP. 
 (d)    If Gatherer delivers the notice referred to
in Section 3.3(c)(i)(B) with respect to a Connection Notice for a Planned CDP, such Planned CDP shall thereafter be a Required Connection CDP. If Gatherer delivers the notice referred to in Section 3.3(c)(ii) with respect to a
Connection Notice for a Planned CDP, Producer may, by notice to Gatherer, accept Gatherer’s proposed fee, in which case such Planned CDP shall be deemed a Required Connection CDP from and after the date of Producer’s notice, and the fee
proposed in Gatherer’s notice shall be charged for Dedicated Saltwater delivered to the Receipt Point at such Planned CDP in lieu of the Gathering Fee. 

(e)    If Gatherer delivers the notice referred to in Section 3.3(c)(ii) with respect to a Connection Notice for a
Planned CDP, and if Producer desires to have such Planned CDP connected to the Gathering System but does not agree to the proposed fee stated in such notice, the Parties shall negotiate in good faith for a period not to exceed 30 Days from the date
of such notice and use reasonable efforts to reach agreement on a fee that would be applicable to the Services performed in respect of Dedicated Saltwater produced through such Planned CDP. If the Parties agree in writing on such fee, such Planned
CDP shall be deemed a Required Connection CDP from and after the date of such agreement, and the fee agreed by the Parties shall be charged for Dedicated Saltwater delivered to the Receipt Point at such Planned CDP in lieu of the Gathering Fee. If
the Parties do not reach agreement within such 30 Day period,

Producer may, at its option by notice to Gatherer, (i) withdraw the Connection Notice with respect to such Planned CDP, in which case, at Producer’s option the entire DSU or any portion
thereof associated with the Wells connected to such CDP shall be permanently released from the dedication and commitment made by Producer under this Agreement, and may be connected to such third party gathering system as Producer may determine, or
(ii) agree to pay the incremental costs incurred by Gatherer to connect such Planned CDP to the Gathering System above the costs that would be incurred by Gatherer to connect such Planned CDP if it were located at the point within [***] miles
of the Gathering System, as of the date of Producer’s delivery of the Connection Notice for such Planned CDP, in which case such Planned CDP shall become a Required Connection CDP from and after the date of Producer’s notice, and the Fees
shall apply to the Services performed in respect to Dedicated Saltwater produced through such Planned CDP. 

(f)    Gatherer shall cause the necessary facilities to be constructed to connect each Required Connection CDP to the
Gathering System and to commence the Services with respect to Dedicated Saltwater produced from such Required Connection 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 Required Connection 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 Required Connection 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 remedy for such delay, 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. 

(g)    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 Required Connection 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

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

 

 
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 Required Connection 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 Required Connection 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. 
 (b)    OMS and MLP hereby agree
to the provisions set forth on Exhibit H.

 ARTICLE 4 

TERM 

Section 4.1    Term. This Agreement shall become effective on the Effective Date and, unless terminated
earlier by mutual agreement of the Parties, shall continue in effect until December 31, 2032 and from Contract Year to Contract Year thereafter until such time as this Agreement is terminated, by notice from any Party to the other Party,
effective at the end of the first Contract Year ending after the 270th Day after the delivery of such notice. 

Section 4.2    Post-Termination. If Gatherer or Producer provides notice of termination of this
Agreement at any time for any reason pursuant to the terms and conditions of this Agreement, Producer shall have the option (to be exercised by providing written notice to Gatherer prior to the termination of the Agreement) to continue to receive
the Services or a portion of the Services for all or any portion of its volumes of Saltwater on a year-to-year basis on the same terms and conditions as the most
favorable terms and conditions that Gatherer continues to provide services that are the same as or similar to the Services or any portion of the Services for volumes of Saltwater on the Disposal System under an agreement with any third party unless
and until terminated by Producer; provided, however, that if the option to extend the term of this Agreement on a year-to-year basis pursuant to this
Section 4.2 is exercised, any obligation of Gatherer to continue to provide the Services pursuant to such option shall not extend beyond December 31, 2042. Gatherer shall provide copies to Producer of any such third
party agreements applicable to volumes of Saltwater accessing the Disposal System upon any notice of termination of this Agreement (whether such notice is delivered by Gatherer or Producer). 

Section 4.3    Survival. Article 1, this Article 4,
Section 9.6, Article 10, Article 11, Article 13, Article 14, Article 15 and Article 16 shall survive termination or expiration of this Agreement.

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 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 Saltwater subject to and in accordance with Section 6.4 during all times of Maintenance on the Disposal System. 

Section 6.3    Capacity Allocations on the Disposal 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 Saltwater to the Disposal System, including the delivery of Firm Capacity Saltwater. If the volume of
Saltwater 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 Saltwater in accordance
with the following: 
 (a)    First, Gatherer shall curtail all Interruptible Saltwater prior to curtailing Firm
Capacity Saltwater. 
 (b)    Second, if additional Disposal System curtailments are required beyond Section
6.3(a), Gatherer shall curtail Firm Capacity Saltwater on the Disposal System. In the event Gatherer curtails some, but not all, Firm Capacity Saltwater on a particular Day, Gatherer shall allocate the capacity of the applicable point on the
relevant System Segment available to each Person entitled to deliver Firm Capacity Saltwater, including Dedicated Saltwater, on a pro rata basis based on the most recent previous Month’s Receipt Point volumes and allowing 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 Producer’s Dedicated Saltwater subject to and in accordance with
Section 6.4 during all times of curtailment on the Disposal System. 

Section 6.4    Trucking. 

(a)    If Gatherer is not able to receive volumes of Dedicated Saltwater 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 Required Connection CDPs under Section 3.3(f), (iii) inability to obtain right of way under Section
3.4(c), (iv) Maintenance under Section 6.2, (v) curtailment under Section 6.3, (vi) insufficient pressure at the Receipt Points under Section 7.1 or (vii) lack of
electrical facilities under Section 7.3, then Gatherer shall truck such volumes to a Disposal Well; 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. 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.

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

 

 
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. 
 ARTICLE 7 

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. 
 ARTICLE 8 

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.

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 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

(“MLP”, and collectively with OMS, “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

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.

on and under said lands and the right to farm, graze and otherwise fully use and enjoy said lands; provided that Owner agrees not to construct or create any obstruction, structure, or engineering work on the herein granted right 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 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
is
                                         
                    (“Owner”), Oasis Midstream Services LLC, whose address is 1001 Fannin, Suite 1500, Houston, Texas 77002, its successors or
assigns (“OMS”), and Oasis Midstream Partners LP, whose address is 1001 Fannin, Suite 1500, Houston, Texas 77002, its successors or assigns (“MLP”, and collectively with OMS, “Grantee”). 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: 

Township              North, Range
             West, 5th P.M. 

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.

a copy of such updated drilling plan to Seller, but not less frequently than on a calendar quarter basis. 
 Section 3.3 CDP
Connections. 
 (a) Seller shall design and develop the Freshwater System for the purpose of providing the Services as and when needed
by Producer to support the upstream development of the Properties, and Seller shall be obligated, at its sole cost and expense, subject to the provisions of this Agreement, to procure, construct, install, own and operate the Freshwater System so as
to timely connect the Required Connection CDPs to the Freshwater System, connect the Freshwater System to a Freshwater supply source, and timely commence providing the full scope of the Services with respect to Freshwater requested by Producer to be
delivered to all Delivery Points located at the CDPs, including the Required Connection CDPs from and after their connection to the Freshwater System, all in accordance with this Section 3.3; provided that the foregoing shall not
preclude Seller from also designing and developing the Freshwater System to accommodate Third Party Freshwater. 
 (b) At Producers option,
Producer may from time to time give notice (a “Connection Notice”) to Seller of each CDP that Producer intends to construct and install that will utilize Freshwater that Producer desires to purchase from Seller pursuant to
this Agreement (each such CDP, a “Planned CDP”). Each Connection Notice shall set forth the target date for the initial utilization of Freshwater at such Planned CDP (the “Target Completion Date”).

 (c) On or before the 30th Day after Producer’s delivery of a Connection Notice
for a Planned CDP, Seller shall, by notice to Producer, (i) agree to connect the Planned CDP covered by such Connection Notice and provide the Services in connection with such CDP, or (ii) state that Seller will not connect the Planned CDP
and perform the Services for the Fees and state the fees that Seller would charge to Producer in lieu of the Fees for connecting such Planned CDP to the Freshwater System and performing the Services in respect of Freshwater delivered to such Planned
CDP in lieu of the Fees. 
 (d) If Seller delivers the notice referred to in Section 3.3(c)(i) with respect to a Connection
Notice for a Planned CDP, such Planned CDP shall thereafter be a Required Connection CDP. If Seller delivers the notice referred to in Section 3.3(c)(ii) with respect to a Connection Notice for a Planned CDP, Producer may, by notice to
Seller, accept Seller’s proposed fees, in which case such Planned CDP shall be deemed a Required Connection CDP from and after the date of Producer’s notice, and the fees proposed in Seller’s notice shall be charged for Freshwater
delivered to the Delivery Point at the Well Pad on which such Planned CDP is located.

 (e) If Seller delivers the notice referred to in
Section 3.3(c)(ii) with respect to a Connection Notice for a Planned CDP, and if Producer desires to have such Planned CDP connected to the Freshwater System but does not agree to the proposed fee stated in such notice, the Parties shall
negotiate in good faith for a period not to exceed 30 Days from the date of such notice and use reasonable efforts to reach agreement on a fee that would be applicable to the Services performed in respect of Freshwater delivered to such Planned CDP.
If the Parties agree in writing on such fee, such Planned CDP shall be deemed a Required Connection CDP from and after the date of such agreement, and the fee agreed by the Parties shall be charged for Freshwater delivered to the Delivery Point at
such Planned CDP in lieu of the Fees. If the Parties do not reach agreement within such 30-Day period, Producer may, at its option by notice to Seller, (i) withdraw the Connection Notice with respect to such Planned CDP, in which case at
Producer’s option, the entire DSU or any portion thereof associated with the Wells connected to such CDP shall be released from the commitment made by Producer under this Agreement. 

(f) Seller shall cause the necessary facilities to be constructed to connect each Required Connection CDP to the Freshwater System and to
commence the Services with respect to Freshwater to be delivered to such Required Connection 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 Freshwater 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 Freshwater 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”). Seller shall provide Producer notice promptly upon Seller’s becoming aware of any reason to believe that it may not be able to
connect a Required Connection CDP to the Freshwater 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 Freshwater to be delivered to such
Required Connection CDP by the Completion Deadline therefor. If and to the extent Seller 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 Seller’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 remedy for such delay, upon mutual agreement
between the Parties, Seller shall truck the Freshwater to such CDP in accordance with Section 6.4 until the Freshwater System is connected to such CDP. 

(g) 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, Seller shall use reasonable efforts to complete the CDP connection within such accelerated timing.

 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 [***] 

 
 (a) Seller 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 Freshwater System, and all such rights in land shall be solely for use by Seller and shall not be shared
with Producer, except as otherwise agreed by Seller; 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 Properties, for the sole purpose of installing, using, maintaining, servicing, inspecting, repairing, operating, replacing, disconnecting and removing all or any portion of the Freshwater System, including
any pipelines, meters and other equipment necessary for the performance of this Agreement; provided, further, that the exercise of these rights by Seller 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 Seller 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 Seller 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 Seller’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 Seller in Producer’s negotiations with the owners of lands covered by the Properties so that Producer’s surface use agreements and Seller’s rights of way
with respect to such lands can be concurrently negotiated and obtained. 
 (b) If Seller cannot obtain the rights of way (on terms and
conditions reasonably acceptable to Seller after diligent pursuit thereof) necessary to connect any Required Connection CDP within 45 Days of delivery of a Connection Notice, then Seller 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 Seller’s standard right of
way agreement within 45 Days of delivery of such Easement Notice. Seller’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
Seller, and Seller’s connection obligations for the applicable CDP shall continue in accordance with the terms of this Agreement; provided, however, that the time required for Seller 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 Seller 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, Seller shall pay Producer for such rights of way an amount per rod equal to the average price per rod paid by Seller for the purchase of rights of way in the Production Area during the preceding 12 month period. If
Seller has not purchased right of way within the Production Area during the previous 12 months, then Seller shall pay Producer for such rights of way an amount per rod equal to the amount per rod paid by Seller under its most recent purchase of
rights of way in the Production Area.

 (c) In the event that Producer fails to obtain such rights of way during
such 45 Day period, Seller shall be released from its obligation under this Agreement to connect such Required Connection CDP to the Freshwater System subject to and in accordance with Section 6.4, and Producer shall have the option to
release the entire DSU or any portion thereof associated with the Wells connected to each CDP from the commitment made by Producer under this Agreement. 

Section 3.5 Cooperation. Because of the interrelated nature of the actions of Producer and Seller 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 Freshwater
System to each Required Connection CDP, Producer and Seller agree to work together in good faith to obtain such Permits, authorizations, consents and rights of way as expeditiously as reasonably practicable. Producer and Seller 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 Seller Obligations. 

(a) OMS and MLP shall be jointly and severally liable for obligations of Seller under this Agreement; provided that
(i) (A) OMS shall be severally, and not jointly, liable for the obligations of Seller to expand or add additional capacity to the Freshwater 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 Seller 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 Seller to expand or add additional capacity to
the Freshwater 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 Seller 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. 
 (b) OMS and MLP hereby agree to the provisions set
forth on Exhibit G.

 replacements to its facilities as Seller 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 will not be affected. Seller shall use reasonable
efforts to schedule any Maintenance to minimize the effect on providing the Services pursuant to this Agreement. Before the beginning of each calendar year, Seller 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. 
 Section 6.3 Capacity Allocations on the Freshwater
System. Subject to the capacity allocations set forth in this Section 6.3, Seller has the right to contract with other Persons for the sales and/or deliveries of Third Party Freshwater, including the sale and/or delivery of Firm
Freshwater. If the volume of Freshwater available for sale and/or delivery out of any System Segment exceeds the capacity of such System Segment at any point relevant to Seller’s service to Producer hereunder, then Seller shall interrupt or
curtail deliveries of Freshwater in accordance with the following: 
 (a) First, Seller shall curtail all Interruptible Freshwater
prior to curtailing Firm Freshwater. 
 (b) Second, if additional Freshwater System curtailments are required beyond
Section 6.3(a) above, Seller shall curtail Firm Freshwater on the Freshwater System. In the event Seller curtails some, but not all, Firm Freshwater on a particular Day, Seller shall (a) allocate the capacity of the applicable point
on the relevant System Segment available to all customers (including Producer) of Firm Freshwater to be used as Flushwater on a pro rata basis based on the most recent previous Month’s Delivery Point volumes and allowing Seller in its sole
discretion to include estimated volumes to be utilized in connection with any New Wells that are connected to a Delivery Point that were not receiving volumes in the previous Month and (b) curtail any volumes of Firm Freshwater requested by all
customers (including Producer) of Firm Freshwater to be used as Fracwater on a pro rata basis based on the reasonably estimated Fracwater volumes nominated or requested by each customer before curtailing any volumes of Firm Freshwater requested by
all customers to be used as Flushwater in the foregoing clause (a), unless otherwise agreed between the Parties; 
 provided
that Seller and Producer may mutually agree to truck Freshwater to the affected Delivery Point(s) subject to and in accordance with Section 6.4 during all times of curtailment on the Freshwater System. 

Section 6.4 Trucking. If Seller is not able to deliver any volumes of Freshwater that Producer requested for delivery
pursuant to Section 7.2 to any CDP on the Freshwater System for any reason, including (a) Force Majeure, (b) delays in construction of Required Connection CDPs under Section 3.3(f), (c) inability to obtain
right of way under Section 3.4(c), (d) Maintenance under Section 6.2, (e) curtailment under Section 6.3, (f) insufficient pressure at the Delivery Points under Section 7.1 or
(g) lack of electrical facilities under Section 7.4, then upon mutual agreement between the Parties, Seller may deliver such volumes by truck to such CDPs, and Producer shall pay the Fees as if such volumes had been delivered by
Seller from the Freshwater System. Within 30 days of commencing trucking operations, Seller shall provide Producer with a written explanation detailing the reason for its inability to deliver volumes from the Freshwater System to the affected CDPs.
The Parties may mutually agree to review capacity expansions of the Freshwater System.

 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 Seller fails or is unable or unwilling for any reason (including Force Majeure) to deliver all volumes of Freshwater that Producer requested for delivery
under this Agreement and provide the Services in accordance therewith, including any failure or inability to truck volumes of Freshwater in accordance with Section 6.4, then the volumes of Freshwater in excess of what Seller is willing
and able to deliver shall be temporarily released from the commitment made by Producer under this Agreement. Producer may immediately purchase such volumes from any Person other than Seller, and Producer shall have the right to enter into
commitments to purchase such volumes of Freshwater from Persons other than Seller, such commitments to be for no longer than reasonably necessary under the circumstances, as determined by Producer in its sole discretion. 

ARTICLE 7 
 PRESSURES;
NOMINATIONS; PRODUCER’S FACILITIES; ELECTRICITY 
 Section 7.1 Pressures at Delivery Points. Seller shall
deliver or cause to be delivered Freshwater to each Delivery Point on the Freshwater System at sufficient pressure for such Freshwater to flow into Producer’s atmospheric tanks at or near the CDPs. Seller shall operate its Measurement
Facilities and the Delivery Points on the Freshwater System at a pressure that allows Producer to receive Freshwater directly into such atmospheric tanks without additional pumps. 

Section 7.2 Freshwater Delivery Nominations. 

(a) Producer shall regularly communicate to Seller the dates on which Producer plans to carry out hydraulic fracturing operations on each Well
Pad and the requested peak and average volumes of Freshwater to be utilized therewith as Fracwater. Producer shall deliver notice to Seller, not less than 30 Days in advance, specifying the dates on which Seller is to commence deliveries of
Freshwater under this Agreement at the Delivery Points at the CDPs to which such Wells are aggregated. Within seven days of receipt of Producer’s notice, Seller shall provide an estimate of the volumes of Freshwater available to be delivered to
the Delivery Points. 
 (b) The Parties agree and acknowledge that Producer may (a) use automated valves to allow volumes of Freshwater
to be used as Flushwater to enter into Producer’s tanks directly from the Freshwater System and/or (b) nominate or request volumes of Freshwater to be used as Flushwater for delivery by Seller under this Agreement. Producer shall have the
right to change its nominations or request for Flushwater at any time and Seller shall use reasonable efforts to accommodate any changes made to Producer’s nominations. 

Section 7.3 Producer Facilities. 

(a) Producer, at its own expense, shall construct, equip, maintain and operate all facilities necessary to receive Freshwater from Seller at
the Delivery Points. Producer shall install and maintain sufficient pressure regulating equipment downstream of the Delivery Points

 in order to keep the pressure of the Freshwater delivered by Seller at the Delivery
Points from exceeding the maximum allowable operating pressure at and downstream of the applicable Delivery Point, as determined by Producer in its sole discretion. Seller shall be responsible for regulating the pressure on the Freshwater System
upstream of the Delivery Points. 
 (b) Producer shall have the right to install facilities and flow Freshwater volumes to operated and
non-operated wells on DSUs located outside, but contiguous with, the Production Area, allowing such wells to utilize Freshwater from the existing Delivery Points or to new Delivery Points mutually agreed between Producer and Seller. Producer shall
provide a list of wells from outside, but on DSUs that are contiguous with, the Producer Area that will utilize Freshwater from such Delivery Points 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 Seller at each such CDP for Seller’s Measurement Facilities. If Seller requires additional electrical power at
such site, then Seller may (at its option) either install, own, operate and maintain a generator at its sole cost and expense or truck such volumes to such CDP at its sole cost and expense subject to and in accordance with Section 6.4.

 ARTICLE 8

 (l) suitable for utilization by Producer as Fracwater and Flushwater and
free of hazardous wastes and other substances that may not be legally transported to or injected in the Wells in accordance with Applicable Laws and Permits and Producer’s operational standards. 

Section 8.2 Non-Spec Freshwater. 

(a) Seller shall test and monitor the Freshwater to be delivered to Producer at the Delivery Points as a Reasonable and Prudent Operator to
ensure that it meets the Freshwater Quality Specifications. If Seller determines or otherwise becomes aware at any time prior to delivery that any Freshwater that will be delivered to Producer at any Delivery Point will not meet the Freshwater
Quality Specifications, then Seller shall provide written notice to Producer. Seller shall be liable for any claims or losses arising out of or related to delivery of Non-Spec Freshwater, including any damages or losses downstream of the applicable
Delivery Point(s); provided that Seller shall not be liable for any such claims or losses if Seller delivers notice to Producer pursuant to this Section 8.2(a) or if Producer otherwise becomes aware that such Freshwater did not
meet the Freshwater Quality Specifications and, in either case, Producer nevertheless accepts such Freshwater. 
 (b) If any Freshwater
sample taken pursuant to Section 8.2(a) fails to meet the Freshwater Quality Specifications (a “Quality Failure”), then Seller shall immediately, but in any event within not more than one Business Day,
(i) notify Producer of such Quality Failure; (ii) provide a lab analysis of the failed Freshwater sample to Producer; and (iii) if directed to do so by Producer, shut down the applicable Delivery Point until such time as the
Freshwater satisfies the Freshwater Quality Specifications. 
 (c) Following any Quality Failure, Seller shall obtain additional Freshwater
samples on a continuous basis until a lab’s analysis confirms that the Freshwater satisfies the Freshwater Quality Specifications. Promptly after a lab’s analysis confirms that the Freshwater satisfies the Freshwater Quality Specifications
(a “Water Correction”), Seller shall (i) notify Producer of the Water Correction and the date that Seller will restart deliveries to the Delivery Point (the “Restart Date”); (ii) provide to
Producer a lab’s analysis of the Freshwater sample confirming such Water Correction; and (iii) restart deliveries to the Delivery Point on the Restart Date. If the Restart Date does not occur within 60 days of the Quality Failure and the
Quality Failure is sufficiently material to prevent Producer from utilizing the Freshwater for its Flushwater operations, then Producer shall have the right to permanently release the affected Delivery Point upon written notice to Seller. 

(d) Any Freshwater that is delivered to Producer that Producer refuses to accept pursuant to this Section 8.2 shall be released
from the commitment made by Producer under this Agreement so that Producer may purchase Freshwater for the affected Wells from any other third party sources. 

ARTICLE 9 
 MEASUREMENT
EQUIPMENT AND PROCEDURES 
 Section 9.1 Measurement Facilities. Seller shall install, own, operate and maintain
Measurement Facilities to measure Freshwater at all the Delivery Points located on the

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

 
 Freshwater System. Measurement Facilities at such Delivery Points shall meet current
industry standards for custody transfer measurement. Each CDP at which Fracwater is utilized will have a separate Delivery Point with separate Measurement Facilities for Fracwater and Flushwater. Producer shall have the right to install check
Measurement Facilities downstream of each such Delivery Point. 
 Section 9.2 Notice of Measurement Facilities Inspection and
Calibration. Each of Producer and Seller shall give two days’ notice to the other in order that the other may, at its option, to 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 Freshwater 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) Seller shall calibrate meters as often as required, as determined by Seller in
accordance with standard industry practices to reasonably assure accurate measurement, but at least twice 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 Seller) 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 Seller, 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 Seller desires a test of any Measurement Facilities not scheduled by a Party
under the provisions of Section 9.3, two days’ advanced notice shall be given to the other and both Producer and Seller 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 Freshwater 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 Freshwater 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
Freshwater Delivered by Truck. Freshwater delivered to the Delivery Points by truck shall be measured 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 Seller develops summary measurement reports for
Producer’s Wells or the Freshwater System, Seller shall provide copies of such reports to Producer upon Producer’s request.

successors and assigns (“MLP”, and collectively with OMS, “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

 In addition to the ROW described above, during any period of time

 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

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

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.

 PAYMENT AGREEMENT FOR RIGHT OF WAY AND EASEMENT AGREEMENT 

This agreement entered into this             day of
                    , 2017 between
                        , husband and wife whose address is
                                        
(“Owner”), Oasis Midstream Services LLC, whose address is 1001 Fannin, Suite 1500, Houston, Texas 77002, its successors or assigns (“OMS”), and Oasis Midstream Partners LP, whose address is 1001 Fannin, Suite 1500, Houston, Texas
77002, its successors or assigns (“MLP”, and collectively with OMS, “Grantee”). 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: 

Township             North, Range
            West, 5th P.M. 

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.
