NOW THEREFORE, for good and valuable consideration, the Parties hereby agree as
follows:
Section 1.Election and Waiver; Consideration Services Contract.
(a)    Election and Waiver. The Partnership hereby (i) elects not to exercise
its ROFR to provide the Proposed Services on the Proposed Services Acreage on
the terms described in the Services Notice and (ii) subject to Section 8, waives
any ROFR it may have or obtain after the Effective Date pursuant to Section
4.1(a) of the Omnibus Agreement solely with respect to the provision of any of
the Proposed Services on any leasehold acreage hereafter acquired by a Noble
Energy Group Member within the Proposed Services Acreage. For the avoidance of
doubt, from the Effective Date through the Rights Termination Date, the ROFR
granted by Noble (on behalf of itself and the Noble Energy Group Members) to the
Partnership pursuant to Section 4.1(a) of the Omnibus Agreement shall continue
to apply to all ROFR Acreage and all ROFR Services, subject to the limited
waiver set forth in clause (ii) of this Section 1(a).

-2-

--------------------------------------------------------------------------------

(b)    Consideration. As consideration for the Partnership’s express limited
waiver in clause (ii) of Section 1(a), Noble shall grant and deliver (or cause
to be granted and delivered) to the Partnership each of the following:
(i)    Infield Gas Gathering. On or before February 24, 2017, Noble will or will
cause appropriate Subsidiaries to execute and deliver to Blanco a gas gathering
agreement (the “Infield Gas Gathering Agreement”) (A) in a form that is mutually
acceptable to the Partnership and Noble, (B) that establishes a fee of no less
than $0.45 / Mcf for gas gathering, (C) pursuant to which Blanco will provide
gas gathering services similar to the services provided by Colorado River DevCo
LP with respect to the Wells Ranch IDP, but expressly excluding gas lift
services and (D) that sets forth a dedication area on leasehold acreage located
within the following (collectively, the “New NBLX Dedication Area”): (x) all
acreage currently held by any Noble Energy Group Member in Reeves County, Texas;
(y) all acreage (the “CWEI Acreage”) located in Reeves County, Texas that is, as
of the Effective Date, owned by Clayton Williams Energy Inc. or any of its
Subsidiaries (collectively and together with any entity surviving the merger
contemplated with Noble, “CWEI”), and (z) all acreage acquired in the future by
any Noble Energy Group Member in Reeves County, Texas.
(ii)    Oil Transportation.
(A)    In connection with the joint venture (the “NBLX JV”) with Plains All
American Pipeline, L.P. (“Plains”) that the Partnership announced on February
13, 2017, Noble and the Partnership have agreed that RROLP will dedicate to the
NBLX JV all of RROLP’s acreage within the Existing NBLX Dedication Area (the
“Initial Oil Transportation Arrangements”), with such dedication becoming
effective concurrently with the closing of the transactions required to
consummate the creation of the NBLX JV. The dedication contemplated by the
Initial Oil Transportation Arrangements excludes acreage owned by any Noble
Energy Group Member other than RROLP.
(B)    Within 30 days of request by the Partnership (and in no event later than
December 31, 2017), Noble will (or will cause the relevant Noble Energy Group
Member to) execute and deliver to the Partnership an oil transportation
agreement (the “Second Oil Transportation Agreement”) (1) in a form that is
mutually acceptable to the Partnership and Noble, (2) that establishes a fee of
no less than $0.75 / Bbl for transportation to a location that is within 85
miles of the Noble Energy Group’s core Permian position, (3) that establishes a
fee of no less than $1.00 / Bbl for transportation to a location that is within
135 miles of the Noble Energy Group’s core Permian position and (4) that
establishes the dedication area as the CWEI Acreage (or a larger area that is
mutually agreeable). Between the Effective Date and the date of execution of the
Second Oil Transportation Agreement, if any Noble Energy Group Member transports
crude oil produced from CWEI Acreage as a spot shipper on the pipeline that is
the subject of the Initial Oil Transportation Arrangements (the “JV Pipeline”),
then the Partnership will reimburse such Noble

-3-

--------------------------------------------------------------------------------

Energy Group Member (x) with respect to oil transported to Crane, Texas, for the
difference between the rate actually paid by such Noble Energy Group Member on
the JV Pipeline and $0.75 / Bbl and (y) with respect to oil transported to
Midland, Texas, for the difference between the rate actually paid by such Noble
Energy Group Member on the JV Pipeline plus the rate actually paid by such Noble
Energy Group Member on the Plains pipeline to Midland and $1.00 / Bbl.
(iii)    Infield Oil Gathering.
(A)    Within 60 days of consummating the acquisition of the CWEI Acreage, Noble
will terminate or will cause to be terminated any contract for the provision of
crude oil gathering within the New NBLX Dedication Area if (and only if) (x) the
only parties to such contract are CWEI and its Subsidiaries, (y) the effect of
such termination is that the midstream services covered by such contract shall
be dedicated (from and after the termination) to the Partnership Group and
(z) no default that cannot be waived unilaterally by the Noble Energy Group
shall result.
(B)    Within 60 days of consummating the acquisition of the CWEI Acreage, Noble
will assign or will cause the assignment from CWEI (or its applicable
Subsidiary), in its capacity as the midstream service provider, to Blanco of any
contract for the provision of crude oil gathering to a third party producer
within the New NBLX Dedication Area so long as CWEI has the right to assign
contracts to Affiliates (for purposes of clarity, if counterparty consent is
required for any such assignment, Noble will only be deemed to not have the
right to assign if it seeks such counterparty consent in good faith and is
unable (notwithstanding the exercise of commercially reasonable efforts) to
obtain it).
(C)    Within 60 days of the Effective Date, Noble will cause RROLP to execute
and deliver to Blanco an amendment to Infield Oil Gathering Agreement that (y)
amends the definition of “Dedication Area” (as defined in the Infield Oil
Gathering Agreement) to include the New NBLX Dedication Area and (z) updates
Section 16.2(b)(ii) of the Infield Oil Gathering Agreement to reflect two core
areas within the “Dedication Area”.
(iv)    Produced Water Services. Within 60 days of the Effective Date, Noble
will cause RROLP to execute and deliver to Blanco an amendment to the PW
Agreement that (y) amends the “Dedication Area” (as defined in the PW Agreement)
to include the New NBLX Dedication Area and (z) updates Section 16.2(b)(ii) of
the PW Agreement to reflect two core areas within the “Dedication Area”.
(c)    Release of Wells Prior to Partnership’s On-Line Date. The Parties
acknowledge that the New NBLX Dedication Area has a number of producing wells
and, upon acquisition of the CWEI Acreage, additional producing properties will
be located within the New NBLX Dedication Area. The Partnership is in the
process of designing and constructing a system to service the New NBLX
Dedication Area. To accommodate the unimpeded development of Noble’s producing
properties within the New NBLX Dedication Area and to allow the Partnership an
opportunity to

-4-

--------------------------------------------------------------------------------

build out to the planned development of the Noble Energy Group, the Partnership
hereby agrees that the wells listed on Exhibit B are hereby released from the PW
Agreement and the Infield Oil Gathering Agreement and shall not be included in
the dedication under the Infield Gas Gathering Agreement. The wells listed on
Exhibit B are intended to be the wells that are producing as of March 1, 2017 or
that Noble Energy Group has indicated will be producing prior to July 1, 2017
(the “Anticipated In-Service Date”) or that Noble and the Partnership have
agreed to release due to their production date occurring prior to any planned
infrastructure. The release described in this clause (c) pertains to the
particular wellbores and all production produced from such wellbores and shall
not constitute a release of any acreage. Exhibit B may be supplemented from time
to time prior to the Anticipated In-Service Date, including within 60 days of
the consummation of the acquisition of CWEI, to reflect the updated drilling
plans of the Noble Energy Group, with such updates being made in good faith to
reflect actual plans and not to undermine the dedications agreed to herein. From
time to time (and within 60 days of the applicable request) the Parties shall
execute, acknowledge, and deliver, or cause to be executed, acknowledged, and
delivered, such further documents and instruments, and take such other and
further actions, as may be reasonably requested by the Noble or the Partnership
in order to effectuate the releases described in this Section 1(c).
(d)    Adjustment to Value if CWEI Transaction Not Consummated. The Parties
acknowledge that the arrangements specified herein are negotiated with the
expectation of the consummation of the acquisition of CWEI by Noble prior to
July 17, 2017 (the “Outside Date”). In the event that the acquisition of CWEI is
not consummated prior to the Outside Date, the foregoing covenants shall be
modified as follows:
(i)    The consideration described in Section 1(b)(i) shall be granted and
delivered as and when described therein, and on or prior to the Outside Date,
the applicable Noble Energy Group Members and the applicable Partnership Group
Members shall assign the agreement from Blanco to Trinity and amend the
agreement to adjust the fee to not less than $0.52 / Mcf for gas gathering, with
such fee being effective as of the first day of the month in which such
amendment is effective.
(ii)    The consideration set forth in Section 1(b)(ii)(A) and Section
1(b)(ii)(B) shall be granted and delivered as described.
(iii)    The consideration set forth in Section 1(b)(iii)(A) and Section
1(b)(iii)(B) shall not be delivered. The consideration set forth in Section
1(b)(iii)(C) shall be granted and delivered.
(iv)    The consideration set forth in Section 1(b)(iv) shall be granted and
delivered as described.
(v)    The consideration set forth in Section 1(b)(v) shall be granted and
delivered as described.
