 * * * * * 

THIS RESTRICTED SECURITY UNIT AWARD AGREEMENT (this “Agreement”), dated as of the Grant Date specified above, is
entered into by and between Blue Mountain Midstream LLC, a Delaware limited liability company (the “Company”), and the Participant specified above, pursuant to the Blue Mountain Midstream LLC 2018 Omnibus Incentive Plan, as in
effect and as amended from time to time (the “Plan”), which is administered by the Committee; and 
 WHEREAS, it has
been determined that it would be in the best interests of the Company to grant the RSUs provided herein to the Participant, as permitted under Article IX of the Plan, subject to the terms and conditions contained herein and in the Plan. 

NOW, THEREFORE, in consideration of the mutual covenants and promises hereinafter set forth and for other good and valuable
consideration, the parties hereto hereby mutually covenant and agree as follows: 
 1. Incorporation By Reference; Plan Document
Receipt. This Agreement is subject in all respects to the terms and provisions of the Plan (including, without limitation, any amendments thereto adopted at any time and from time to time unless such amendments are expressly intended not to
apply to the Award provided hereunder), all of which terms and provisions are made a part of and incorporated in this Agreement as if they were each expressly set forth herein. Except as provided otherwise herein, any capitalized term not defined in
this Agreement shall have the same meaning as is ascribed thereto in the Plan. The Participant hereby acknowledges receipt of a true copy of the Plan and that the Participant has read the Plan carefully and fully understands its content. In the
event of any conflict between the terms of this Agreement and the terms of the Plan, the terms of this Agreement shall control. 
 2.
Grant of Restricted Security Unit Award. The Company hereby grants to the Participant, as of the Grant Date specified above, the number of RSUs specified above. Except as otherwise provided by the Plan, the Participant agrees and
understands that nothing contained in this Agreement provides, or is intended to provide, the Participant with any protection against potential future dilution of the Participant’s interest in the Company for any reason, and no adjustments
shall be made for dividends in cash or other property, distributions or other rights in respect of the Units underlying the RSUs, except as otherwise specifically provided for in the Plan or this Agreement. 













 3. Vesting; Forfeiture. 

(a) Vesting Generally. Subject to the provisions of Sections 3(b) to 3(d) hereof, the RSUs subject to this Award shall
vest in three substantially equal installments (33.3%, 33.3% and 33.4%, respectively) (each installment, a “Tranche”) on each of the first three anniversaries of the Participant’s commencement of employment with the Company on
April 2, 2018 (the “Start Date”) (each such anniversary, a “Vesting Date”), such that 100% of the RSUs subject to this Award shall be vested as of the third anniversary of the Start Date, provided that
the Participant has not incurred a Termination prior to each Vesting Date. There shall be no proportionate or partial vesting in the periods prior to each Vesting Date and all vesting shall occur only on the appropriate Vesting Date, subject to the
Participant not incurring a Termination prior to the applicable Vesting Date. The continuous employment or service of the Participant shall not be deemed interrupted, and the Participant shall not be deemed to have incurred a Termination, by reason
of the transfer of the Participant’s employment or service among the Company and/or its Subsidiaries and/or Affiliates. 
 (b) Good
Leaver Termination. In the event of the Participant’s Termination (i) due to the Participant’s death or Disability, (ii) by the Company or other employing Affiliate without Cause or (iii) by the Participant for Good
Reason (each, a “Good Leaver Termination”), in each case, prior to the earlier of the third Vesting Date or the consummation of a Change in Control, subject to the Participant’s (or the Participant’s estate’s)
execution and non-revocation of a general release of claims in favor of the Company (in the same form as the release attached to the Participant’s employment agreement, if any) within fifty-two (52) days of such Good Leaver Termination, the Participant shall vest, on the date of such Good Leaver Termination, in a pro-rata portion of the then-current
Tranche, with such pro-rata portion calculated by multiplying the number of RSUs subject to such Tranche by a fraction, (A) the numerator of which is the number of days that the Participant was employed
with the Company or any of its Subsidiaries from the Start Date or the most recent Vesting Date, as applicable, until the date of such Good Leaver Termination and (B) the denominator of which is three hundred and sixty-five (365). Any RSUs that
remain unvested after the foregoing acceleration (the “Contingent RSUs”) shall remain outstanding for the three (3) month period immediately following the Participant’s Good Leaver Termination (the “Tail
Period”), and in the event a Change in Control occurs during the Tail Period, all of the Contingent RSUs shall vest as of the date of such Change in Control. If a Change in Control does not occur during the Tail Period, all of the
Contingent RSUs shall be forfeited immediately as of the end of the Tail Period. 
 (c) Change in Control. All unvested RSUs shall
fully vest upon the consummation of a Change in Control, provided that the Participant has not incurred a Termination prior to such date. 

(d) Committee Discretion to Accelerate Vesting. In addition to the foregoing, the Committee may, in its sole discretion, accelerate
vesting of the RSUs at any time and for any reason. 
 (e) Forfeiture. Subject to the terms of this
Section 3, all unvested RSUs shall be forfeited immediately upon the Participant’s Termination for any reason or no reason.

 4. Delivery of Units. 

(a) General. Subject to Section 4(b) below, within sixty (60) days following the first to occur of
(i) the consummation of a Change in Control (provided that an event shall not be considered to be a Change in Control for purposes of this Section 4(a) unless such event is also a “change in
ownership,” a “change in effective control” or a “change in the ownership of a substantial portion of the assets” of the Company within the meaning of Section 409A of the Code), (ii) the Participant’s Termination
for any or no reason (provided that an event shall be considered a Termination for purposes of this Section 4(a) only to the extent the Termination also constitutes a “separation from service” under Code
Section 409A), and (iii) the third Vesting Date (each, a “Liquidity Event”), the Participant shall receive (A) the number of Units that corresponds to the number of RSUs that are vested as of the applicable Liquidity
Event (the “Vested RSUs”), (B) cash in an amount equal to the aggregate Fair Market Value of the Units underlying the Vested RSUs, or (C) some combination of the foregoing, as determined by the Committee in its sole discretion.

 (b) Blackout Periods. If the Participant is subject to any Company “blackout” policy or other trading restriction
imposed by the Company on the date a distribution of Units would otherwise be made pursuant to Section 4(a) hereof, such distribution shall be instead made on the earlier of (i) the date that the Participant is not
subject to any such policy or restriction and (ii) the later of (A) the end of the calendar year in which such distribution would otherwise have been made and (B) a date that is immediately prior to the expiration of two and one-half months following the date such distribution would otherwise have been made hereunder. 
 5.
Appraisal Right. If the Participant, in good faith, disagrees with the Board’s determination of the Fair Market Value of the Units (exclusively limited to the Board’s determination pursuant to clause (b) of the
definition of Fair Market Value in the Plan) (the “Unit FMV”), the Participant may request that the Board’s determination be reviewed by a mutually acceptable nationally recognized valuation firm (the
“Appraiser”), taking into account relevant factors in accordance with applicable law (including applicable tax rules) (the “Appraisal”). The Participant shall have sixty (60) calendar days from the date on
which the Company provides the Participant with the Board’s determination to provide the Company with written notice of such dispute (the “Dispute Notice”), which Dispute Notice shall include an acknowledgement of the
Participant’s potential responsibility for fees and expenses payable pursuant to this dispute provision. If the Participant provides the Company with a Dispute Notice, the Company and the Participant shall work together in good faith to resolve
the issues in dispute. If the Company and the Participant are unable to resolve all such disputed issues within ten (10) business days following the Company’s receipt of the Dispute Notice, the Participant may request the Appraisal. Any
determination of the Appraiser pursuant to the foregoing provisions shall be a final and binding determination of the Unit FMV on the Participant and the Company. If such Appraiser’s determination of the Unit FMV is less than or equal to 110%
of the Unit FMV determined by the Board, all costs and expenses associated with the Appraisal shall be borne by the Participant up to a maximum of $250,000 in the aggregate, with the remaining costs and expenses borne by the Company. If the
Appraiser’s determination of the Disputed Value is more than 110% of the Unit 

  
 3 














 
FMV determined by the Board, all costs and expenses associated with the Appraisal shall be borne by the Company. If the Appraisal with respect to the Unit FMV results in a greater cash amount
payable in respect of the Vested RSUs pursuant to Section 4(a)(B) or Section 4(a)(C) above, the additional cash amount shall be paid to the Participant within forty-five (45) days of the
Appraisal completion date. 
 6. Dividend Equivalent Rights; Rights as a Unitholder. Cash dividends on the number of Units
issuable hereunder shall be credited to a dividend book entry account on behalf of the Participant with respect to each RSU granted to the Participant, provided that such cash dividends shall not be deemed to be reinvested in Units and shall
be held uninvested and without interest and paid in cash at the same time that the Units underlying the RSUs are delivered to the Participant in accordance with Section 4 hereof. Equity or property dividends on Units shall
be credited to a dividend book entry account on behalf of the Participant with respect to each RSU granted to the Participant, provided that such equity or property dividends shall be paid in (i) Units, (ii) in the case of a spin-off, securities of the entity that is spun-off from the Company, or (iii) other property in the same form as is applicable to Unit holders, as applicable and in each
case, at the same time that the Units underlying the RSUs are delivered to the Participant in accordance with Section 4 hereof. Except as otherwise provided herein, the Participant shall have no rights as a unitholder with
respect to any Units covered by any RSU unless and until the Participant has become the holder of record of such Units. 
 7. Non-Transferability. No portion of the RSUs may be sold, assigned, transferred, encumbered, hypothecated or pledged by the Participant, other than to the Company as a result of forfeiture of the RSUs as
provided herein. 
 8. Governing Law. All questions concerning the construction, validity and interpretation of this Agreement
shall be governed by, and construed in accordance with, the laws of the State of Texas, without regard to the choice of law principles thereof. 

9. Withholding of Tax; Section 409A. 

(a) The Participant agrees and acknowledges that the Company shall have the power and the right to deduct or withhold, or require the
Participant to remit to the Company, an amount sufficient to satisfy any federal, state, local and foreign taxes of any kind (including, but not limited to, the Participant’s FICA and SDI obligations) which the Company, in its good faith
discretion, deems necessary to be withheld or remitted to comply with the Code and/or any other applicable law, rule or regulation with respect to the RSUs, and if the withholding requirement cannot be satisfied, the Company may otherwise refuse to
issue or transfer any Units otherwise required to be issued pursuant to this Agreement. Without limiting the foregoing, the Company, in its sole discretion, may withhold Units otherwise deliverable to the Participant hereunder with an aggregate Fair
Market Value equal up to the Participant’s total income and employment taxes imposed as a result of the vesting and/or settlement of the RSUs, but only to the extent permitted by applicable accounting rules so as not to affect accounting
treatment. 
 (b) The intent of the parties is that the RSUs granted hereunder comply with Code Section 409A, and accordingly, to the
maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. However, in no event whatsoever shall the Company be liable for any additional tax, interest or penalty that may be imposed on the Participant by Code
Section 409A or damages for failing to comply with Code Section 409A. 

  
 4 














 (c) As noted above, a termination of service shall not be deemed to have occurred for
purposes of this Agreement unless such termination is also a “separation from service” within the meaning of Code Section 409A, and for purposes of any such provision of this Agreement, references to a “termination,”
“termination of service” or like terms shall mean “separation from service.” Notwithstanding anything to the contrary in this Agreement, if the Participant is deemed on the date of termination to be a “specified
employee” within the meaning of that term under Code Section 409A(a)(2)(B), then payment of cash and/or delivery of Units in respect of the Vested RSUs pursuant to Section 4 shall not be made until the date which
is the earlier of (i) the expiration of the six (6)-month period measured from the date of such “separation from service” of the Participant, and (ii) the date of the Participant’s death, to the extent required under Code
Section 409A. Upon the expiration of the foregoing delay period, the payment of cash and/or delivery of Units in respect of the Vested RSUs delayed pursuant to this Section 9(c) shall be made in one installment. 

(d) Whenever a payment of cash and/or delivery of Units under this Agreement is to occur within a period of a number of days, the actual date
of payment of cash and/or delivery of Units within the specified period shall be within the sole discretion of the Company. 
 (e)
Notwithstanding any other provision of this Agreement to the contrary, in no event shall any payment of cash and/or delivery of Units under this Agreement that constitutes “nonqualified deferred compensation” for purposes of Code
Section 409A be subject to offset by any other amount unless otherwise permitted by Code Section 409A. 
 10.
Legend. The Company may at any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates, if any, representing Units issued pursuant to this Agreement. The Participant
shall, at the request of the Company, promptly present to the Company any and all certificates, if any, representing Units acquired pursuant to this Agreement in the possession of the Participant in order to carry out the provisions of this
Section 10. 
 11. Securities Representations. This Agreement is being entered into by
the Company in reliance upon the following express representations and warranties of the Participant. The Participant hereby acknowledges, represents and warrants that:

Act and in this connection the Company is relying in part on the Participant’s representations set forth in this Section 11. 

(b) If the Participant is deemed an affiliate within the meaning of Rule 144 of the Securities Act, the Units issuable hereunder must be held

and the Company is under no obligation to register such Units (or to file a “re-offer prospectus”). 

  
 5

is then available to the public, and (C) other terms and conditions of Rule 144 or any exemption therefrom are complied with, and (ii) any sale of the Units issuable hereunder may be made only in limited amounts in accordance with the

Affiliates to terminate the Participant’s employment or service at any time, for any reason and with or without Cause. 
 16.
Transfer of Personal Data. The Participant authorizes, agrees and unambiguously consents to the transmission by the Company (or any Subsidiary) of any personal data information related to the RSUs awarded under this Agreement for
legitimate business purposes (including, without limitation, the administration of the Plan). This authorization and consent is freely given by the Participant. 

17. Compliance with Laws. The grant of RSUs and the issuance of Units hereunder shall be subject to, and shall comply with, any
applicable requirements of any foreign and U.S. federal and state securities laws, rules and regulations (including, without limitation, the provisions of the Securities Act, the Exchange Act and in each case any respective rules and regulations
promulgated thereunder) and any other law, rule regulation or exchange requirement applicable thereto. The Company shall not be obligated to issue the RSUs or any Units pursuant to this Agreement if any such issuance would violate any such
requirements. As a condition to the settlement of the RSUs, the Company may require the Participant to satisfy any qualifications that may be necessary or appropriate to evidence compliance with any applicable law or regulation.
