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.

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 Xxxxx 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.

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 Xxxxx 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.

(j) 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 Xxxxx 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 Xxxxx from any other third party sources.

COMMISSION, 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 Xxxxx or the Freshwater System, Seller shall provide copies of such reports to Producer upon Producer’s request.

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 0000 Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000, its successors or assigns (“OMS”), and Oasis Midstream Partners LP, whose address is 0000 Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000, 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:

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.
