 6. New Article 18. The following new Article 18 shall be inserted immediately
following the conclusion of Article 17 of the Agreement Terms and Conditions: 
 Article 18 

Pipeline Unavailability 

Section 18.1 Effectiveness; Pipeline Unavailability. The Parties agree that this Article 18 shall be effective as
of the Trucked Water Services Commencement Date. 
 (a) It is the intention of the Parties to use the Individual System for
all Dedicated Production. To accommodate operational upsets and periods of increased flow (such as the occurrence of Pre-Connection Water during the Pre-Connection Period), the Parties have agreed under Section 2.3(b) that, during
Pipeline Unavailability, Producer shall elect to either (i) exercise the Trucking Election or (ii) cease producing Dedicated Production until the end of the Pipeline Unavailability, as provided in Section 18.2. To the extent
Producer exercises its Trucking Election, this Article 18 shall govern with respect to the Trucked Volumes and the other matters set forth herein, rather than Articles 4, 7 (other than Section 7.3 as it applies to
Trucked Volumes delivered to a SWD Trucking Facility that fail to meet the quality requirements of Section 18.3(d)) and 9 and Sections 5.1, 5.2, 5.3, 5.4, and 5.6. 

(b) The Parties agree that during Pipeline Unavailability, Producer shall not have the right to temporary services under
Sections 3.3(a) and 3.3(b) of the Agreement or to a temporary release under Section 2.4(b)(ii) of the Agreement except to the extent that Midstream Co fails to provide Trucked Water Services. 

(c) If Midstream Co fails to connect a Well or a Separator Facility to the Individual System by the On-Line Deadline, Producer
may exercise its Trucking Election for the duration of the resulting Pipeline Unavailability, rather than exercising its right to a permanent release under Section 2.4(a)(i) and Section 2.4(a)(ii). If Midstream Co fails to
connect a Well or Separator Facility to the Individual System by the On-Line Deadline, but prior to such On-Line Deadline, the Parties have agreed that the connection of the Well or Separator Facility did not need to occur until after Pre-Connection
Water has started flowing, then the resulting Pipeline Unavailability shall not entitle Producer to a permanent release under Section 2.4(a)(i) and Section 2.4(a)(ii) until such time as the agreed upon connection date has
passed. 
 Section 18.2 Exercise of Trucking Election. 

(a) If Producer expects a Well or Separator Facility to be completed prior to its connection to the Individual System,
resulting in a Pipeline Unavailability, Producer shall give Midstream Co at least 72 hours’ advance notice that Dedicated Production is expected to be produced from the applicable Well or available at the applicable Separator Facility. After
the applicable Well or 

  
 Amendment 01 –
Page 6 
 Second Amended and Restated Produced Water Services Agreement 

Green River Produced Water Agreement 

GRMU03-PW 

 
Separator Facility is connected to the Individual System, following the Trucked Water Services Commencement Date, Midstream Co shall deliver notice to Producer of any Pipeline Unavailability
pursuant to Section 5.5. 
 (b) Once Producer or Midstream Co, as applicable, has delivered notice to the other
Party that a Pipeline Unavailability is expected (or has occurred), Producer will inform Midstream Co whether Producer elects to exercise its Trucking Election or to cease producing Dedicated Production until the end of the Pipeline Unavailability.
If Producer exercises the Trucking Election during the Pre-Connection Period, Producer shall coordinate with the water hauling trucks and arrange for transportation of the Dedicated Production to the SWD Trucking Facility at its sole cost and
expense until the end of the Pre-Connection Period. At all other times during a Pipeline Unavailability, including when Pre-Connection Water is occurring after the expiration of the Pre-Connection Period, Midstream Co shall coordinate with the water
hauling trucks and arrange for transportation of the Dedicated Production to the SWD Trucking Facility as part of the Trucked Water Services unless Producer has elected to cease producing Dedicated Production. 

Section 18.3 Delivery of and Title to Trucked Volumes. 

(a) Trucked Water Services Obligation. Upon the exercise of a Trucking Election, Midstream Co shall cause an Approved
SWD Vendor to accept delivery of, take title to, store, handle and dispose of Dedicated Production that is delivered by truck to a SWD Trucking Facility. Upon the exercise of a Trucking Election, Midstream Co may, in its sole discretion, also accept
delivery of, take title to, store, handle and dispose of other Product delivered by truck to a SWD Trucking Facility. The volumes that are actually delivered by truck shall be referred to as “Trucked Volumes”. 

(b) Consistent Volumes. The Trucked Volumes delivered to the applicable SWD Trucking Facility shall be at a rate of
delivery that is as uniform as reasonably possible in accordance with Producer’s drilling, completion, and frac schedule. 

(c) Title and Custody. Title to and risk of loss to the Trucked Volumes and all contents thereof shall pass from
Producer to Approved SWD Vendor when delivered into Approved SWD Vendor’s storage tanks at the SWD Trucking Facility, unless the Parties otherwise agree in writing. 

(d) Quality. Producer represents and warrants that all Trucked Volumes delivered to an Approved SWD Vendor may lawfully
be disposed of in Class II disposal wells. Midstream Co’s performance of Trucked Water Services for any Trucked Volumes that do not meet such requirement shall not relieve Producer from any liability for Producer’s breach of the foregoing
representation and warranty nor serve as a waiver of any rights or remedies available to Midstream Co therefor. 

  
 Amendment 01 –

GRMU03-PW 

 (e) Prohibition on Skimming. The Party that coordinates the water hauling
trucks shall direct the Transporter not to skim, transfer, sell, or otherwise remove hydrocarbons or Trucked Volumes from trucks after receipt by such Transporter and prior to such Trucked Volumes being received by the Approved SWD Vendor. If the
Approved SWD Vendor alleges that the Trucked Volumes delivered appear to have been handled in a manner inconsistent with the foregoing sentence, Producer shall corporate with Midstream Co and the Approved SWD Vendor in a review and analysis and, if
required by the Approved SWD Vendor, take corrective action in a timely manner. If Transporters engaged by Producer fail to comply with the directions received, then Midstream Co may direct Producer to use a different Transporter. 

Section 18.4 Unavailability of a SWD Trucking Facility. If for any reason there is a disruption of receipts at the
SWD Trucking Facility, the Parties shall work in good faith to find a mutually agreeable resolution. If for any reason Midstream Co receives reimbursements in respect of trucking as a result of an originally scheduled SWD Trucking Facility being
unable to accept deliveries, Midstream Co shall disclose such reimbursements on the applicable invoice and pass through such reimbursements to Producer if Producer paid the costs of the applicable Transporter directly. 

Section 18.5 Testing; Non-Conforming Product. If requested by Midstream Co, Producer shall obtain water samples for
analyses and retain appropriate qualified personnel to conduct analyses following methodologies considered appropriate in the industry or shall permit Midstream Co to obtain such samples. 

Section 18.6 Producer’s Grant of Access. Producer hereby grants to Midstream Co, and shall grant to each
Transporter, without warranty of title, either express or implied, to the extent that it may lawfully and is contractually permitted to do so without the incurrence of additional expense, the rights of ingress and egress with respect to, and the
right to access, all lands constituting Dedicated Properties for the purposes of (a) transporting Trucked Volumes, and (b) obtaining water samples as described in Section 18.5. 

Section 18.7 Information. Producer agrees that information it supplies to Midstream Co regarding anticipated
volumes of Dedicated Production and Trucked Volumes may be shared with an Approved SWD Vendor to the extent required by the applicable Approved SWD Vendor to assist in planning and operations, and Producer agrees to provide additional information
regarding anticipated volumes of Dedicated Production and Trucked Volumes to the extent requested by Midstream Co in response to inquiries from an Approved SWD Vendor (so long as Midstream Co is required to deliver the requested information in order
to comply with Midstream Co’s contractual arrangements with such Approved SWD Vendor). Under Section 3.1, Midstream Co has the right to hold certain meetings with Producer, and at the request of Midstream Co, one of such meetings
per year may be held in conjunction with the Approved SWD Vendor to discuss confer regarding planned activities. 

Section 18.8 Indemnification in Respect of Trucked Volumes. Without in any way limiting any indemnification
obligation otherwise set forth in the Agreement, the Parties agree that the indemnification obligations of Producer set forth in Section 7.3 and Section 15.2(b) apply to Trucked Volumes delivered to a SWD Trucking Facility.

engages the Transporter shall take all reasonable measures to ensure that the invoicing procedures that Midstream Co has negotiated with the Approved SWD Vendor are used, including notation of the geographic area to which the services pertain.
Midstream Co shall provide a written copy of such procedures to Producer upon request.

the Agreement Terms and Conditions: 
 Article 18 

Pipeline Unavailability 

Section 18.1 Effectiveness; Pipeline Unavailability. The Parties agree that this Article 18 shall be effective as
of the Trucked Water Services Commencement Date. 
 (a) It is the intention of the Parties to use the Individual System for
all Dedicated Production. To accommodate operational upsets and periods of increased flow (such as the occurrence of Pre-Connection Water during the Pre-Connection Period), the Parties have agreed under Section 2.3(b) that, during
Pipeline Unavailability, Producer shall elect to either (i) exercise the Trucking Election or (ii) cease producing Dedicated Production until the end of the Pipeline Unavailability, as provided in Section 18.2. To the extent
Producer exercises its Trucking Election, this Article 18 shall govern with respect to the Trucked Volumes and the other matters set forth herein, rather than Articles 4, 7 (other than Section 7.3 as it applies to
Trucked Volumes delivered to a SWD Trucking Facility that fail to meet the quality requirements of Section 18.3(d)) and 9 and Sections 5.1, 5.2, 5.3, 5.4, and 5.6. 

(b) The Parties agree that during Pipeline Unavailability, Producer shall not have the right to temporary services under
Sections 3.3(a) and 3.3(b) of the Agreement or to a temporary release under Section 2.4(b)(ii) of the Agreement except to the extent that Midstream Co fails to provide Trucked Water Services. 

(c) If Midstream Co fails to connect a Well or a Separator Facility to the Individual System by the On-Line Deadline, Producer
may exercise its Trucking Election for the duration of the resulting Pipeline Unavailability, rather than exercising its right to a permanent release under Section 2.4(a)(i) and Section 2.4(a)(ii). If Midstream Co fails to
connect a Well or Separator Facility to the Individual System by the On-Line Deadline, but prior to such On-Line Deadline, the Parties have agreed that the connection of the Well or Separator Facility did not need to occur until after Pre-Connection
Water has started flowing, then the resulting Pipeline Unavailability shall not entitle Producer to a permanent release under Section 2.4(a)(i) and Section 2.4(a)(ii) until such time as the agreed upon connection date has
passed. 
 Section 18.2 Exercise of Trucking Election. 

(a) If Producer expects a Well or Separator Facility to be completed prior to its connection to the Individual System,
resulting in a Pipeline 

  
 Amendment 01 –
Page 6 
 Second Amended and Restated Produced Water Services Agreement 

Gunnison River Produced Water Agreement 

GUBR04-PW 

 
Unavailability, Producer shall give Midstream Co at least 72 hours’ advance notice that Dedicated Production is expected to be produced from the applicable Well or available at the
applicable Separator Facility. After the applicable Well or Separator Facility is connected to the Individual System, following the Trucked Water Services Commencement Date, Midstream Co shall deliver notice to Producer of any Pipeline
Unavailability pursuant to Section 5.5. 
 (b) Once Producer or Midstream Co, as applicable, has delivered notice
to the other Party that a Pipeline Unavailability is expected (or has occurred), Producer will inform Midstream Co whether Producer elects to exercise its Trucking Election or to cease producing Dedicated Production until the end of the Pipeline
Unavailability. If Producer exercises the Trucking Election during the Pre-Connection Period, Producer shall coordinate with the water hauling trucks and arrange for transportation of the Dedicated Production to the SWD Trucking Facility at its sole
cost and expense until the end of the Pre-Connection Period. At all other times during a Pipeline Unavailability, including when Pre-Connection Water is occurring after the expiration of the Pre-Connection Period, Midstream Co shall coordinate with
the water hauling trucks and arrange for transportation of the Dedicated Production to the SWD Trucking Facility as part of the Trucked Water Services unless Producer has elected to cease producing Dedicated Production. 

Section 18.3 Delivery of and Title to Trucked Volumes. 

(a) Trucked Water Services Obligation. Upon the exercise of a Trucking Election, Midstream Co shall cause an Approved
SWD Vendor to accept delivery of, take title to, store, handle and dispose of Dedicated Production that is delivered by truck to a SWD Trucking Facility. Upon the exercise of a Trucking Election, Midstream Co may, in its sole discretion, also accept
delivery of, take title to, store, handle and dispose of other Product delivered by truck to a SWD Trucking Facility. The volumes that are actually delivered by truck shall be referred to as “Trucked Volumes”. 

(b) Consistent Volumes. The Trucked Volumes delivered to the applicable SWD Trucking Facility shall be at a rate of
delivery that is as uniform as reasonably possible in accordance with Producer’s drilling, completion, and frac schedule. 

(c) Title and Custody. Title to and risk of loss to the Trucked Volumes and all contents thereof shall pass from
Producer to Approved SWD Vendor when delivered into Approved SWD Vendor’s storage tanks at the SWD Trucking Facility, unless the Parties otherwise agree in writing. 

(d) Quality. Producer represents and warrants that all Trucked Volumes delivered to an Approved SWD Vendor may lawfully
be disposed of in Class II disposal wells. Midstream Co’s performance of Trucked Water Services for any Trucked Volumes that do not meet such requirement shall not relieve Producer from any liability for Producer’s breach of the foregoing
representation and warranty nor serve as a waiver of any rights or remedies available to Midstream Co therefor. 

  
 Amendment 01 –

GUBR04-PW 

 (e) Prohibition on Skimming. The Party that coordinates the water hauling
trucks shall direct the Transporter not to skim, transfer, sell, or otherwise remove hydrocarbons or Trucked Volumes from trucks after receipt by such Transporter and prior to such Trucked Volumes being received by the Approved SWD Vendor. If the
Approved SWD Vendor alleges that the Trucked Volumes delivered appear to have been handled in a manner inconsistent with the foregoing sentence, Producer shall corporate with Midstream Co and the Approved SWD Vendor in a review and analysis and, if
required by the Approved SWD Vendor, take corrective action in a timely manner. If Transporters engaged by Producer fail to comply with the directions received, then Midstream Co may direct Producer to use a different Transporter. 

Section 18.4 Unavailability of a SWD Trucking Facility. If for any reason there is a disruption of receipts at the
SWD Trucking Facility, the Parties shall work in good faith to find a mutually agreeable resolution. If for any reason Midstream Co receives reimbursements in respect of trucking as a result of an originally scheduled SWD Trucking Facility being
unable to accept deliveries, Midstream Co shall disclose such reimbursements on the applicable invoice and pass through such reimbursements to Producer if Producer paid the costs of the applicable Transporter directly. 

Section 18.5 Testing; Non-Conforming Product. If requested by Midstream Co, Producer shall obtain water samples for
analyses and retain appropriate qualified personnel to conduct analyses following methodologies considered appropriate in the industry or shall permit Midstream Co to obtain such samples. 

Section 18.6 Producer’s Grant of Access. Producer hereby grants to Midstream Co, and shall grant to each
Transporter, without warranty of title, either express or implied, to the extent that it may lawfully and is contractually permitted to do so without the incurrence of additional expense, the rights of ingress and egress with respect to, and the
right to access, all lands constituting Dedicated Properties for the purposes of (a) transporting Trucked Volumes, and (b) obtaining water samples as described in Section 18.5. 

Section 18.7 Information. Producer agrees that information it supplies to Midstream Co regarding anticipated
volumes of Dedicated Production and Trucked Volumes may be shared with an Approved SWD Vendor to the extent required by the applicable Approved SWD Vendor to assist in planning and operations, and Producer agrees to provide additional information
regarding anticipated volumes of Dedicated Production and Trucked Volumes to the extent requested by Midstream Co in response to inquiries from an Approved SWD Vendor (so long as Midstream Co is required to deliver the requested information in order
to comply with Midstream Co’s contractual arrangements with such Approved SWD Vendor). Under Section 3.1, Midstream Co has the right to hold certain meetings with Producer, and at the request of Midstream Co, one of such meetings
per year may be held in conjunction with the Approved SWD Vendor to discuss confer regarding planned activities.

 Section 18.8 Indemnification in Respect of Trucked Volumes. Without
in any way limiting any indemnification obligation otherwise set forth in the Agreement, the Parties agree that the indemnification obligations of Producer set forth in Section 7.3 and Section 15.2(b) apply to Trucked Volumes
delivered to a SWD Trucking Facility. 
 Section 18.9 Invoices from Approved SWD Vendor. The Party that engages
the Transporter shall take all reasonable measures to ensure that the invoicing procedures that Midstream Co has negotiated with the Approved SWD Vendor are used, including notation of the geographic area to which the services pertain. Midstream Co
shall provide a written copy of such procedures to Producer upon request.
