 Section 3. Administration. 

(a) Authority of the Committee. The Plan shall be administered by the Committee, subject to Section 3(b); provided,

(v) determine whether, to what extent, and under what circumstances Awards may be vested, settled, exercised, canceled, or forfeited; 

(vi) interpret and administer the Plan and any instrument or agreement relating to an Award made under the Plan; 

(vii) establish, amend, suspend, or waive such rules and regulations and appoint such agents as it shall deem appropriate for the proper
administration of the Plan; and 
 (viii) make any other determination and take any other action that the Committee deems necessary or
desirable for the administration of the Plan. 
 The Committee may correct any defect, supply any omission, or reconcile any inconsistency in the Plan, in
any Award or in any Award Agreement in such manner and to such extent as the Committee deems necessary or appropriate. Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations, and other decisions under or
with respect to the Plan or any Award shall be within the sole discretion of the Committee, may be made at any time, and shall be final, conclusive, and binding upon all Persons, including the General Partner, the Partnership, any of their
respective Affiliates, any Participant, and any beneficiary of any Award. 
 (b) Authority of a Subcommittee of the Committee. If the
Board is not functioning as the Committee, then at any time that a member of the Committee is not a Qualified Member, any action of the Committee relating to an Award granted or to be granted to a Participant who is then subject to Section 16
of the Exchange Act in respect of the Partnership may be taken either 

  
 5 

 
(i) by a subcommittee, designated by the Committee, composed solely of two or more Qualified Members, (ii) by the Committee but with each such member who is not a Qualified Member abstaining
or recusing himself or herself from such action; provided, however, that upon such abstention or recusal the Committee remains composed solely of two or more Qualified Members, or (iii) by the full Board. Any such action described in
clauses (i), (ii), or (iii) of the preceding sentence shall be deemed to be the action of the Committee for all purposes of the Plan. 

(c) Limitation of Liability. The Committee and each member thereof shall be entitled to, in good faith, rely or act upon any report or
other information furnished to him or her by any Employee, the General Partner’s or the Partnership’s legal counsel, independent auditors, consultants, or any other agents assisting in the administration of the Plan. Members of the
Committee and any Employee acting at the direction or on behalf of the Committee shall not be personally liable for any action or determination taken or made in good faith with respect to the Plan, and shall, to the fullest extent permitted by law,
be indemnified and held harmless by the General Partner with respect to any such action or determination. 
 Section 4.
Units. 
 (a) Limits on Units Deliverable. Subject to adjustment as provided in Section 4(c) and Section 7, the
number of Common Units and Subordinated Units, in the aggregate, that may be delivered with respect to Awards under the Plan is             . If any Award is forfeited, cancelled,
exercised, settled in cash, or otherwise terminates or expires without the actual delivery of Units pursuant to such Award (the grant of Restricted Units is not a delivery of Units for this purpose unless and until the Restricted Period for such
Restricted Units lapses), or if any Units under an Award are held back to cover the exercise price or tax withholding (including the withholding of Units with respect to an Award of Restricted Units), then, in either such case, the Units underlying
such Awards that are so forfeited, cancelled, exercised, settled in cash or that otherwise terminate or expire without the actual delivery of Units and Units so held back shall be available to satisfy future Awards under the Plan. Notwithstanding
any other provision of the Plan to the contrary, the aggregate grant date fair value (computed as of the date of grant in accordance with applicable financial accounting rules) of all Awards granted to any Director during any single calendar year
shall not exceed $500,000; provided, however, that such limitation shall be $600,000 in the first year a Person becomes a Director. There shall not be any limitation on the number of Awards that may be paid in cash. 

(b) Sources of Units Deliverable under Awards. Any Units delivered pursuant to an Award shall consist, in whole or in part, of
(i) Common Units acquired in the open market; (ii) Common Units or Subordinated Units acquired from the Partnership (including newly issued Common Units or Subordinated Units), any Affiliate of the Partnership, or any other Person; or
(iii) any combination of the foregoing, as determined by the Committee in its discretion. 
 (c) Adjustments. 

(i) Certain Restructurings. Upon the occurrence of any “equity restructuring” event that could result in an additional
compensation expense to the General Partner or the Partnership pursuant to the provisions of ASC Topic 718 if adjustments to Awards with respect to such event were discretionary, the Committee shall equitably adjust the number and type of

  
 6 

 
Units (or other securities or property) covered by each outstanding Award and the terms and conditions, including the exercise price and performance criteria (if any), of such Award to equitably
reflect such event and shall adjust the number and type of Units (or other securities or property) with respect to which Awards may be granted under the Plan after such event; provided, however, that no adjustment to any Award shall
materially reduce the benefit to a Participant immediately prior to such adjustment without the consent of such Participant. Upon the occurrence of any other similar event that would not result in an accounting charge under ASC Topic 718 if the
adjustment to Awards with respect to such event were subject to discretionary action, the Committee shall have complete discretion to adjust Awards and the number and type of Units (or other securities or property) with respect to which Awards may
be granted under the Plan in such manner as it deems appropriate with respect to such other event. In the event the Committee makes any adjustment pursuant to the foregoing provisions of this Section 4(c), the Committee shall make a
corresponding and proportionate adjustment with respect to the maximum number of Units that may be delivered with respect to Awards under the Plan as provided in Section 4(a) and the kind of Units or other securities available for grant under
the Plan. 
 (ii) Other Adjustments. Subject to, and without limiting the scope of, the provisions of Section 4(c)(i), in the
event that the Committee determines that any distribution (whether in the form of cash, Units, other securities, or other property), recapitalization, split, reverse split, reorganization, merger, Change of Control, consolidation, split-up,
spin-off, combination, repurchase, or exchange of Units or other securities of the Partnership, issuance of warrants or other rights to purchase Units or other securities of the Partnership, or other similar transaction or event affects the Units
such that an adjustment is determined by the Committee, in its sole discretion, to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, then the Committee
shall, in such manner as it may deem equitable, adjust any or all of (A) the number and type of Units (or other securities or property) with respect to which Awards may be granted, (B) the number and type of Units (or other securities or
property) subject to outstanding Awards, and (C) the grant or exercise price with respect to any Award or, if deemed appropriate, make provision for a cash payment to the holder of an outstanding Award; provided, that the number of Units
subject to any Award shall always be a whole number. Further, upon the occurrence of any event described in the preceding sentence, the Committee, acting in its sole discretion without the consent or approval of any holder, may effect one or more of
the following alternatives, which may vary among individual holders and which may vary among Awards: 
 (A) remove any
applicable forfeiture restrictions on any Award; 
 (B) accelerate the time of exercisability or the time at which the
Restricted Period shall lapse to a specific date specified by the Committee; 
 (C) require the mandatory surrender to the
General Partner or the Partnership by selected holders of some or all of the outstanding Awards held by such holders (irrespective of whether such Awards are then subject to a Restricted Period or other restrictions pursuant to the Plan) as of a
date specified by the Committee, in which event the Committee shall thereupon cancel such Awards and cause the General Partner, the Partnership or any of their respective Affiliates to pay to each holder an amount of cash per Unit equal to the per
Unit value as determined by the Committee as of the date 

  
 7 

 
determined by the Committee to be the date of cancellation and surrender of such Awards less the exercise price, if any, applicable to such Awards; provided, however, that to the extent
the exercise price of an Option or UAR exceeds such per Unit value as determined by the Committee, no consideration will be paid with respect to that Award; 

(D) cancel Awards that remain subject to a Restricted Period as of a date specified by the Committee without payment of any
consideration to the Participant for such Awards; or 
 (E) make such adjustments to Awards then outstanding as the Committee
deems appropriate to reflect such event (including, without limitation, the substitution of new awards for Awards); provided, however, that the Committee may determine in its sole discretion that no adjustment is necessary to Awards then
outstanding. 
 Section 5. Eligibility. Any Employee, Consultant or Director shall be eligible to be designated a
Participant and receive an Award under the Plan. 
 Section 6. Awards. 

(a) Options and UARs. The Committee shall have the authority to determine the Employees, Consultants, and Directors to whom Options or
UARs shall be granted, the number of Units to be covered by each Option or UAR, the exercise price therefor, the Restricted Period and other conditions and limitations applicable to the exercise of the Option or UAR, including the following terms
and conditions and such additional terms and conditions, as the Committee shall determine, that are not inconsistent with the provisions of the Plan. 

(i) Exercise Price. The exercise price per Unit purchasable under an Option or subject to a UAR shall be determined by the Committee at
the time the Option or UAR is granted but, except with respect to substitute Awards pursuant to Section 6(f)(viii), may not be less than the Fair Market Value of a Unit as of the date of grant of such Option or UAR. 

(ii) Time and Method of Exercise. The Committee shall determine the exercise terms and the Restricted Period, if any, with respect to
an Option or UAR, which may include a provision for accelerated vesting upon the achievement of specified performance goals or other events and the method or methods by which payment of the exercise price with respect to an Option or UAR may be made
or deemed to have been made, which may include cash, check acceptable to the General Partner, withholding Units having a Fair Market Value on the exercise date equal to the relevant exercise price from the Award, a “cashless-broker”
exercise through procedures approved by the General Partner, other securities or other property, a note (in a form acceptable to the General Partner), or any combination of the foregoing methods. 

(iii) Forfeitures. Except as otherwise provided in the terms of the Award Agreement, upon termination of a Participant’s
employment with (or service to) the General Partner and its Affiliates or membership on the Board, whichever is applicable, for any reason during the applicable Restricted Period, all outstanding Options and UARs awarded to the Participant shall be
automatically forfeited on such termination. 

  
 8 

 (b) Restricted Units and Phantom Units. The Committee shall have the authority to
determine the Employees, Consultants, and Directors to whom Restricted Units or Phantom Units shall be granted, the number of Restricted Units or Phantom Units to be granted to each such Participant, the applicable Restricted Period, the conditions
under which the Restricted Units or Phantom Units may become vested or forfeited, and such other terms and conditions as the Committee may establish with respect to such Awards, including whether DERs are granted with respect to the Phantom Units.

 (i) UDRs. To the extent determined by the Committee, in its discretion, the Award Agreement for a grant of Restricted Units may
provide that distributions made by the Partnership with respect to the Restricted Units shall be subject to the same forfeiture and other restrictions as the Restricted Unit and, if restricted, such distributions shall be held, with or without
interest or other earnings credit (as determined by the Committee), until the Restricted Unit vests or is forfeited with the UDR being paid or forfeited at the same time, as the case may be. Absent such a restriction on the UDRs in the Award
Agreement, UDRs shall be paid to the holder of the Restricted Unit without restriction at the same time as cash distributions are paid by the Partnership to its unitholders. 

(ii) Forfeitures. Except as otherwise provided in the terms of the applicable Award Agreement, upon termination of a Participant’s
employment with (or service to) the General Partner and its Affiliates or membership on the Board, whichever is applicable, for any reason during the applicable Restricted Period, all outstanding, unvested Restricted Units and Phantom Units awarded
to the Participant shall be automatically forfeited on such termination. 
 (iii) Lapse of Restrictions. 

(A) Phantom Units. Unless otherwise provided in the applicable Award Agreement, upon or as soon as reasonably practical
following the vesting of each Phantom Unit, subject to Section 8(b), the Participant shall be entitled to settlement of such Phantom Unit and shall receive one Unit (or such greater or lesser number of Units as may be provided pursuant to the
applicable Award Agreement) or an amount in cash equal to the Fair Market Value (for purposes of this Section 6(b)(iii), as calculated on the last day of the Restricted Period) of a Unit (or such greater or lesser number of Units as may be
provided pursuant to the applicable Award Agreement) or a combination thereof, as determined by the Committee in its discretion and as provided in the applicable Award Agreement. 

(B) Restricted Units. Upon or as soon as reasonably practicable following the vesting of each Restricted Unit, subject
to Section 8(b), the Participant shall be entitled to have the restrictions removed from his or her Unit certificate (or book entry account, as applicable). 

(c) DERs. The Committee shall have the authority to determine the Employees, Consultants, and Directors to whom DERs are granted,
whether such DERs are tandem or separate Awards, whether such DERs shall be paid directly to the Participant, be credited to a bookkeeping account (with or without interest or other earnings credit), any vesting restrictions and payment provisions
applicable to the DERs, and such other provisions or restrictions as determined by the Committee in its discretion, all of which shall be specified in the applicable 

  
 9 

 
Award Agreements. Distributions in respect of DERs shall be credited as of the distribution dates during the period between the date an Award is granted to a Participant and the date such Award
vests, is exercised, is distributed or expires, as determined by the Committee. Such DERs shall be converted to cash, Units, Restricted Units, or Phantom Units by such formula and at such times and subject to such limitations as may be determined by
the Committee. Tandem DERs may be subject to the same or different vesting restrictions as the underlying Award, or be subject to such other provisions or restrictions as determined by the Committee in its discretion. 

(d) Bonus Units and Awards in Lieu of Obligations. The Committee is authorized to grant Units as a bonus or to grant Units in lieu of
obligations to pay cash or deliver other property under the Plan or under other plans or compensatory arrangements to such Employees, Consultants and Directors and in such amounts as the Committee, in its discretion, may select. Bonus Units or
Awards granted hereunder shall be subject to such other terms and conditions as shall be determined by the Committee. 
 (e) Other
Unit-Based Awards; Cash Awards. Other Unit-Based Awards may be granted under the Plan to such Employees, Consultants, and Directors as the Committee, in its discretion, may select. An Other Unit-Based Award shall be an award denominated or
payable in, valued in or otherwise based on or related to Units, in whole or in part. The Committee shall determine the terms and conditions of any Other Unit-Based Award, including whether such Other Unit-Based Award (or any portion thereof) is
fully vested when granted and, if such Other Unit-Based Award (or any portion thereof) is not fully vested when granted, the conditions under which such Other Unit-Based Award (or the unvested portion thereof) may become vested or forfeited. Other Unit-Based Awards may be paid in cash, Units (including Restricted Units) or any combination thereof as provided in the applicable Award Agreement. Cash Awards, as an element of or supplement to, or independent of
any other Award under the Plan, may also be granted pursuant to this Section 6(e). 
 (f) Certain Provisions Applicable to
Awards. 
 (i) Awards May Be Granted Separately or Together. Awards may, in the discretion of the Committee, be granted either
alone or in addition to, in tandem with, or in substitution for any other Award granted under the Plan or any award granted under any other plan of the General Partner or any Affiliate of the General Partner. Awards granted in addition to or in
tandem with other Awards or awards granted under any other plan of the General Partner, the Partnership or any of their respective Affiliates may be granted either at the same time as or at a different time from the grant of such other Awards or
awards. 
 (ii) Limits on Transfer of Awards. 

(A) Except as provided in Section 6(f)(ii)(C), each Option and UAR shall be exercisable only by the Participant during the
Participant’s lifetime, or by the Person to whom the Participant’s rights shall pass by will or the laws of descent and distribution. 

(B) Except as provided in Section 6(f)(ii)(C), no Award and no right under any such Award may be assigned, alienated,
pledged, attached, sold or otherwise transferred or encumbered by a Participant other than by will or the laws of descent and distribution and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void
and unenforceable against the General Partner, the Partnership or any of their respective Affiliates. 
 (C) The Committee
may provide in an Award Agreement or in its discretion that an Award may, on such terms and conditions as the Committee may from time to time establish, be transferred by a Participant without consideration to any “family member” of the
Participant, as defined in the instructions to use of the Form S-8 Registration Statement under the Securities Act of 1933, as amended, or any related family trust, limited partnership or other transferee specifically approved by the Committee. 

  
 10 

 (iii) Term of Awards. The term of each Award shall be for such period as may be determined
by the Committee. 
 (iv) Issuance of Units. The Units or other securities of the Partnership delivered pursuant to an Award may be
evidenced in any manner deemed appropriate by the Committee in its sole discretion, including, without limitation, in the form of a certificate issued in the name of the Participant or by book entry, electronic or otherwise and shall be subject to
such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any securities exchange upon which such Units or other securities are then listed, and
any applicable laws, and the Committee may cause a legend or legends to be inscribed on any certificates, if applicable, to make appropriate reference to such restrictions. 

(v) Consideration for Grants. To the extent permitted by applicable law, Awards may be granted for such consideration, including
services, as the Committee shall determine. 
 (vi) Delivery of Units or other Securities and Payment by Participant of
Consideration. Notwithstanding anything in the Plan or any Award Agreement to the contrary, the Partnership shall not be required to issue or deliver any certificates or make any book entries evidencing Units pursuant to the exercise or vesting
of any Award unless and until the Board or the Committee has determined, with advice of counsel, that (A) the issuance of such Units is in compliance with all applicable laws, regulations of governmental authorities, and, if applicable, the
requirements of any securities exchange on which the Units are listed or traded, and (B) the Units are covered by an effective registration statement or applicable exemption from registration. In addition to the terms and conditions provided
herein, the Board or the Committee may require that a Participant make such reasonable covenants, agreements, and representations as the Board or the Committee, in its discretion, deems advisable in order to comply with any such laws, regulations,
or requirements. Without limiting the generality of the foregoing, the delivery of Units pursuant to the exercise or vesting of an Award may be deferred for any period during which, in the good faith determination of the Committee, the Partnership
is not reasonably able to obtain or deliver Units pursuant to such Award without violating applicable law or the applicable rules or regulations of any governmental agency or authority or securities exchange. No Units or other securities shall be
delivered pursuant to any Award until payment in full of any amount required to be paid pursuant to the Plan or the applicable Award Agreement (including any exercise price or tax withholding) is received by the General Partner. Such payment may be
made by such method or methods and in such form or forms as the Committee shall determine, 

  
 11 

 
including cash, other Awards, withholding of Units, cashless broker exercises with simultaneous sale, or any combination thereof; provided that the combined value, as determined by the
Committee, of all cash and cash equivalents and the Fair Market Value of any such Units or other property so tendered to the General Partner, as of the date of such tender, is at least equal to the full amount required to be paid to the General
Partner pursuant to the Plan or the applicable Award Agreement. 
 (vii) Change of Control. If specifically provided in an Award
Agreement, upon a Change of Control the Award may automatically vest and be payable or become exercisable in full, as the case may be. 

(viii) Substitute Awards. Awards may be granted under the Plan in substitution of similar awards held by individuals who are or who
become Employees, Consultants or Directors in connection with a merger, consolidation or acquisition by the Partnership or one of its Affiliates of another entity or the securities or assets of another entity (including in connection with the
acquisition by the Partnership or one of its Affiliates of additional securities of an entity that is an existing Affiliate of the Partnership). To the extent permitted by Section 409A, such substitute Awards that are Options or UARs may have
exercise prices less than the Fair Market Value of a Unit on the date of the substitution. 
 (ix) Prohibition on Repricing of Options
and UARs. Subject to the provisions of Section 4(c) and Section 7(c), the terms of outstanding Award Agreements may not be amended without the approval of the Partnership’s unitholders so as to: 

(A) reduce the Unit exercise price of any outstanding Options or UARs, 

(B) grant a new Option, UAR or other Award in substitution for, or upon the cancellation of, any previously granted Option or UAR that has the
effect of reducing the exercise price thereof, 
 (C) exchange any Option or UAR for Units, cash, or other consideration when the exercise
price per Unit under such Option or UAR exceeds the Fair Market Value of the underlying Units, or 
 (D) take any other action that
would be considered a “repricing” of an Option or UAR under the listing standards of the New York Stock Exchange or, if the Units are not then-listed on such exchange, to the extent applicable, on any other national securities exchange on
which the Units are listed. 
 Subject to Section 4(c), Section 7(c) and Section 8(n), the Committee shall have the
authority, without the approval of the Partnership’s unitholders, to amend any outstanding Award to increase the per Unit exercise price of any outstanding Options or UARs or to cancel and replace any outstanding Options or UARs with the grant
of Options or UARs having a per Unit exercise price that is equal to or greater than the per Unit exercise price of the original Options or UARs.

 Section 7. Amendment and Termination. Except to the extent prohibited by
applicable law: 
 (a) Amendments to the Plan. Except as required by applicable law or the rules of the principal securities exchange
on which the Units are traded and subject to Section 7(b) below, the Board or the Committee may amend, alter, suspend, discontinue, or terminate the Plan in any manner, including increasing the number of Units available for Awards under the
Plan, without the consent of any partner, Participant, other holder or beneficiary of an Award, or other Person. 
 (b) Amendments to
Awards. Subject to Section 7(a), the Committee may waive any conditions or rights under, amend any terms of, or alter any Award theretofore granted (including, without limitation, requiring or allowing for an election to settle an Award in
cash), provided no change in any Award shall materially reduce the benefit to a Participant immediately prior to such change without the consent of such Participant. 

(c) Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. The Committee is hereby authorized to make
adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including the events described in Section 4(c)) affecting the Partnership or the financial statements of the
Partnership, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended
to be made available under the Plan or such Award. 
 Section 8. General Provisions. 

(a) No Rights to Award. No Person shall have any claim to be granted any Award under the Plan, and there is no obligation for
uniformity of treatment of Participants. The terms and conditions of Awards need not be the same with respect to each recipient. 

(b) Tax Withholding. Unless other arrangements have been made that are acceptable to the General Partner or any of its
Affiliates, the General Partner or any Affiliate of the General Partner is authorized to deduct, withhold, or cause to be deducted or withheld, from any Award, from any payment due or transfer made under any Award, or from any compensation or other
amount owing to a Participant the amount (in cash, Units, including Units that would otherwise be issued pursuant to such Award, or other property) of any applicable taxes payable in respect of the grant or settlement of an Award, its exercise, the
lapse of restrictions thereon, or any other payment or transfer under an Award or under the Plan and to take such other action as may be necessary in the opinion of the General Partner or any Affiliate of the General Partner to satisfy its
withholding obligations for the payment of such taxes. In the event that Units that would otherwise be issued pursuant to an Award are used to satisfy such withholding obligations, the number of Units that may be withheld or surrendered shall be
limited to the number of Units that have a Fair Market Value on the date of withholding equal to the aggregate amount of such liabilities based on the minimum statutory withholding rates for federal, state, local and foreign income tax and payroll
tax purposes that are applicable to such taxable income; provided, however, that such withholding may be based on rates in excess of the minimum statutory withholding rates if (x) the Committee (i) determines that such withholding
would not result in adverse accounting, tax or other consequences to the General Partner or any of its Affiliates (other than immaterial administrative, reporting or similar consequences) and (ii) authorizes such withholding at such greater
rates and (y) the holder of such Award consents to such withholding at such greater rates. 

  
 13 

 (c) No Right to Employment or Service Relationship. The grant of an Award shall not be
construed as giving a Participant the right to be retained in the employ of the General Partner or any of its Affiliates, to continue providing consulting services, or to remain on the Board, as applicable. Furthermore, the General Partner or an
Affiliate of the General Partner may at any time dismiss a Participant from employment or his or her service relationship, free from any liability or any claim under the Plan, unless otherwise expressly provided in the Plan, any Award Agreement or
other written agreement between any such entity and a Participant. 
 (d) Governing Law. The validity, construction, and effect of
the Plan and any rules and regulations relating to the Plan shall be determined in accordance with the laws of the State of Delaware without regard to its conflict of laws principles. 

(e) Severability. If any provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal, or unenforceable in any
jurisdiction or as to any Person or Award, or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to the applicable law or, if it cannot be construed
or deemed amended without, in the determination of the Committee, materially altering the intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction, Person, or Award, and the remainder of the Plan and any such Award
shall remain in full force and effect. 
 (f) Other Laws. The Committee may refuse to issue or transfer any Units or other
consideration under an Award if, in its sole discretion, it determines that the issuance or transfer of such Units or such other consideration might violate any applicable law or regulation or the rules of the principal securities exchange on which
the Units are then traded, or entitle the Partnership or an Affiliate of the Partnership to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the General Partner by a Participant, other holder, or beneficiary
in connection with the exercise of such Award shall be promptly refunded to the relevant Participant, holder or beneficiary. 
 (g) No
Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the General Partner or any Affiliate of the General Partner and a Participant
or any other Person. To the extent that any Person acquires a right to receive payments from the General Partner or any Affiliate of the General Partner pursuant to an Award, such right shall be no greater than the right of any general unsecured
creditor of the General Partner or such Affiliate. 
 (h) No Fractional Units. No fractional Units shall be issued or delivered
pursuant to the Plan or any Award, and the Committee shall determine in its sole discretion whether cash, other securities, or other property shall be paid or transferred in lieu of any fractional Units or whether such fractional Units or any rights
thereto shall be canceled, terminated, or otherwise eliminated with or without consideration. 
 (i) Headings. Headings are given to
the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision hereof. 

(j) Facility Payment. Any amounts payable hereunder to any individual under legal disability or who, in the judgment of the Committee,
is unable to properly manage his financial 

  
 14 

 
affairs, may be paid to the legal representative of such individual, or may be applied for the benefit of such individual in any manner that the Committee may select, and the General Partner, the
Partnership and their respective Affiliates shall be relieved of any further liability for payment of such amounts. 
 (k) Participation
by Affiliates. In making Awards to Employees employed by, or Consultants providing services to, an Affiliate of the General Partner, the Committee shall be acting on behalf of the Affiliate of the General Partner, and to the extent the
Partnership has an obligation to reimburse the General Partner for compensation paid to Employees or Consultants for services rendered for the benefit of the Partnership, such reimbursement payments may be made by the Partnership directly to the
Affiliate of the General Partner, and, if made to the General Partner, shall be received by the General Partner as agent for the Affiliate of the General Partner. 

(l) Allocation of Costs. Nothing herein shall be deemed to override, amend, or modify any cost sharing arrangement, omnibus agreement,
or other arrangement between the General Partner, the Partnership, and any of their respective Affiliates regarding the sharing of costs between such entities. 

(m) Gender and Number. Words in the masculine gender shall include the feminine gender, the plural shall include the singular and the
singular shall include the plural. 
 (n) Compliance with Section 409A. Nothing in the Plan or any Award Agreement shall operate
or be construed to cause the Plan or an Award that is subject to Section 409A to fail to comply with the requirements of Section 409A. The applicable provisions of Section 409A are hereby incorporated by reference and shall control
over any Plan or Award Agreement provision in conflict therewith or that would cause a failure of compliance thereunder, to the extent necessary to resolve such conflict or obviate such failure. Subject to any other restrictions or limitations
contained herein, in the event that a “specified employee” (as defined under Section 409A) becomes entitled to a payment under an Award that constitutes a “deferral of compensation” (as defined under Section 409A) on
account of a “separation from service” (as defined under Section 409A), to the extent required by the Code, such payment shall not occur until the date that is six months plus one day from the date of such separation from service. Any
amount that is otherwise payable within the six-month period described herein will be aggregated and paid in a lump sum without interest. Notwithstanding any provision herein to the contrary, none of the Board, the Committee, the Partnership, the
General Partner or any of their respective Affiliates makes any representations that any Awards (or payments with respect to any Awards) are exempt from or compliant with Section 409A and in no event shall the Board, the Committee, the
Partnership, the General Partner or any of their respective Affiliates be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by any Participant on account of non-compliance with Section 409A.

 (o) No Guarantee of Tax Consequences. None of the Board, the Committee, the Partnership, the General Partner, or any of their
respective Affiliates (i) provides or has provided any tax advice to any Participant or any other Person or makes or has made any assurance, commitment or guarantee that any federal, state, local or other tax treatment will (or will not) apply
or be available to any Participant or other Person or (ii) assumes any liability with respect to any tax or associated liabilities to which any Participant or other Person may be subject. 

  
 15 

 (p) Clawback. To the extent required by applicable law or any applicable securities
exchange listing standards, or as otherwise determined by the Committee, Awards and amounts paid or payable pursuant to or with respect to Awards shall be subject to the provisions of any applicable clawback policies or procedures adopted by the
General Partner or the Partnership, which clawback policies or procedures may provide for forfeiture, repurchase, or recoupment of Awards and amounts paid or payable pursuant to or with respect to Awards. Notwithstanding any provision of the Plan or
any Award Agreement to the contrary, the General Partner and the Partnership reserve the right, without the consent of any Participant or beneficiary of any Award, to adopt any such clawback policies and procedures, including such policies and
procedures applicable to the Plan or any Award Agreement with retroactive effect. 
 Section 9. Term of the Plan. The
Plan shall be effective on the date on which it is adopted by the Board and shall continue until the earliest of (i) the date terminated by the Board or the Committee, (ii) the date that all Units available under the Plan have been
delivered to Participants, or (iii) the 10th anniversary of the date on which the Plan is adopted by the Board. However, unless otherwise expressly provided in the Plan or in an applicable Award Agreement, any Award granted prior to such
termination, and the authority of the Board or the Committee under the Plan or an Award Agreement to amend, alter, adjust, suspend, discontinue, or terminate any such Award or to waive any conditions or rights under such Award, shall extend beyond
such termination date.

IPO AWARD GRANT NOTICE 

 EXHIBIT A 

IPO AWARD AGREEMENT 
 This
IPO Award Agreement (this “Agreement”) is made as of the Date of Grant set forth in the Grant Notice to which this Agreement is attached (the “Date of Grant”) by and between Black Stone Minerals GP, L.L.C., a
Delaware limited liability company (the “General Partner”), and              (“Employee”). Capitalized terms used but not specifically defined herein shall
have the meanings specified in the Plan or the Grant Notice. 
 1. Award. Effective as of the Date of Grant, the General
Partner hereby grants to Employee the number of Restricted Units (all of which shall consist of Common Units) set forth in the Grant Notice (the “Restricted Units”) on the terms and conditions set forth in the Grant Notice, this
Agreement and the Plan, which is incorporated herein by reference as a part of this Agreement. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan shall control. 

2. Issuance Mechanics. The General Partner shall (a) cause a certificate or certificates representing such Common Units to
be registered in the name of Employee, or (b) cause such Common Units to be held in book-entry form. If a certificate is issued, it shall be delivered to and held in custody by the General Partner and shall bear such legend or legends as
the Committee deems appropriate in order to reflect the Forfeiture Restrictions (as defined below) and to ensure compliance with the terms and provisions of this Agreement, the rules, regulations and other requirements of the United States
Securities and Exchange Commission, any applicable federal or state securities laws or any securities exchange on which the Common Units are then listed or quoted. If the Common Units are held in book-entry form, then such entry will reflect that
the Common Units are subject to the restrictions of this Agreement. 
 3. Forfeiture Restrictions. 

(a) The Restricted Units may not be sold, assigned, pledged, exchanged, hypothecated or otherwise transferred, encumbered or disposed of
except as provided in this Agreement or the Plan. In the event of the termination of Employee’s employment with the Employer, except as otherwise expressly provided in this Agreement, Employee shall immediately and without any further action by
the General Partner, forfeit and surrender for no consideration all of the Restricted Units with respect to which the Forfeiture Restrictions have not lapsed as of the date of such termination. The prohibition against transfer and the obligation to
forfeit and surrender the Restricted Units upon termination of Employee’s employment as provided in this Section 3(a) are referred to herein as the “Forfeiture Restrictions.” The Forfeiture Restrictions shall be binding
upon and enforceable against any transferee of the Restricted Units. 
 (b) In the event of a Qualifying Termination (as defined in
Section 3(d)) prior to the vesting of all of the Restricted Units, subject to Employee’s compliance with the release requirement described in Section 3(f), the Forfeiture Restrictions on the Applicable Restricted Units (as defined in
Section 3(d)) shall automatically lapse and the Applicable Restricted Units 

  
 Exhibit A-1 

 
shall immediately thereafter become Earned Units so long as Employee has remained continuously employed by the Employer from the Date of Grant through the date of such Qualifying Termination;
provided, however, that if such Qualifying Termination occurs within 24 months following a Change of Control, the Forfeiture Restrictions on all unvested Restricted Units will lapse automatically in accordance with Section 3(e) without any
further action by the General Partner or the Partnership and such Restricted Units shall immediately thereafter become Earned Units so long as Employee has remained continuously employed by the Employer from the Date of Grant through the date of
such Qualifying Termination. 
 (c) In the event of a termination of Employee’s employment due to Employee’s Disability (as
defined in Section 3(d)) or death prior to the vesting of all of the Restricted Units, the Forfeiture Restrictions on all unvested Restricted Units will lapse automatically in accordance with Section 3(e) without any further action by the
General Partner or the Partnership and such Restricted Units shall immediately thereafter become Earned Units so long as Employee has remained continuously employed by the Employer from the Date of Grant through the date of such termination. 

(d) As used herein: 
 (i)
“Applicable Restricted Units” means the number of Restricted Units equal to A minus B, where “A” is the product of (x) is the number of Restricted Units granted hereunder and (y) a fraction, the numerator
of which is the number of days during the period beginning on the Vesting Commencement Date and ending on the date of Employee’s Qualifying Termination, and the denominator of which is the number of days during the period beginning on the
Vesting Commencement Date and ending on the fourth anniversary of the Vesting Commencement Date; and “B” is the cumulative number of Restricted Units that became vested prior to the date of Employee’s Qualifying Termination. 

(ii) “Cause” has the meaning assigned to such term in Employee’s severance agreement with the General Partner or one of
its Affiliates; provided, however, that if Employee does not have a severance agreement with the General Partner or one of its Affiliates or if such agreement does not define the term “Cause,” then “Cause” means a
determination by two-thirds of the Board that Employee: 
 (1) willfully and continually failed to substantially perform
Employee’s duties to the Partnership and its Affiliates (other than a failure resulting from Employee’s Disability); 

(2) willfully engaged in conduct that is demonstrably and materially injurious to the Partnership, the General Partner or any
of their respective Affiliates, monetarily or otherwise; 
 (3) has been convicted of, or has plead guilty or nolo
contendere to, a misdemeanor involving moral turpitude or a felony; 
 (4) has committed an act of fraud, or material
embezzlement or material theft, in each case, in the course of Employee’s employment relationship with the Employer or one of its Affiliates, or 

(5) has materially breached any obligations of Employee under any written agreement (including any non-compete,
non-solicitation or confidentiality covenants) entered into between Employee and the Partnership, the General Partner or any of their respective Affiliates. 

  
 Exhibit A-2 

 Notwithstanding the foregoing, except for a failure, breach or refusal that, by its nature, cannot reasonably be
expected to be cured, Employee shall have 30 days following the delivery of written notice by the Employer or one of its Affiliates within which to cure any actions or omissions described in clauses (1), (2), (4) or (5) constituting Cause;
provided however, that, if the Employer reasonably expects irreparable injury from a delay of 30 days, the Employer or one of its Affiliates may give Employee notice of such shorter period within which to cure as is reasonable under the
circumstances, which may include the termination of Employee’s employment without notice and with immediate effect. 
 (iii)
“Disability” means Employee’s incapacity, due to accident, sickness or another circumstance, that renders Employee unable to perform the essential functions of Employee’s job function, with reasonable accommodation, for a
period of at least 90 consecutive days or 120 days in any 12-month period. 
 (iv) “Good Reason” has the meaning assigned
to such term in Employee’s severance agreement with the General Partner or one of its Affiliates; provided, however, that if Employee does not have a severance agreement with the General Partner or one of its Affiliates or if such
agreement does not define the term “Good Reason,” then “Good Reason” means the occurrence of any of the following events without Employee’s written consent: 

(1) a reduction in Employee’s total compensation other than a general reduction in compensation that affects all
similarly situated employees in substantially the same proportions; 
 (2) a relocation of Employee’s principal place
of employment by more than 50 miles from the location of Employee’s principal place of employment as of the Date of Grant; 

(3) any material breach by the Partnership or the General Partner of any material provision of this Agreement; 

(4) a material, adverse change in Employee’s title, authority, duties or responsibilities (other than while Employee has
a Disability); 
 (5) a material adverse change in the reporting structure applicable to Employee; or 

(6) following a Change of Control, either (x) a failure of the General Partner or one of its Affiliates to continue in
effect any benefit plan or compensation arrangement in which Employee was participating immediately prior to such Change of Control or (y) the taking of any action by the General Partner or one of its Affiliates that adversely affects
Employee’s participation in, 

  
 Exhibit A-3 

 
or materially reduces Employee’s benefits or compensation under, any such benefit plan or compensation arrangement, unless, in the case of either clause (x) or (y), there is substituted
a comparable benefit plan or compensation arrangement that is at least economically equivalent to the benefit plan or compensation arrangement being terminated or in which Employee’s participation is being adversely affected or Employee’s
benefits or compensation are being materially reduced. 
 Notwithstanding the foregoing provisions of this definition or any other provision of the
Agreement to the contrary, any assertion by Employee of a termination for Good Reason shall not be effective unless all of the following conditions are satisfied: (A) Employee must provide written notice to the General Partner of the existence
of the condition(s) providing grounds for termination for Good Reason within 30 days of the initial existence of such grounds; (B) the condition(s) specified in such notice must remain uncorrected for 30 days following the General
Partner’s receipt of such written notice; and (C) the date of Employee’s termination of employment must occur within 60 days after the initial existence of the condition(s) specified in such notice. 

(v) “Qualifying Termination” means a termination of Employee’s employment by reason of (1) a termination of
Employee’s employment by the Employer without Cause, or (2) Employee’s resignation for Good Reason. 
 (e) The Restricted
Units shall be released from the Forfeiture Restrictions in accordance with the vesting schedule set forth in the Grant Notice. The Restricted Units with respect to which the Forfeiture Restrictions lapse without forfeiture are referred to
herein as the “Earned Units.” As soon as administratively practicable following the release of any Restricted Units from the Forfeiture Restrictions, the General Partner shall, as applicable, either deliver to Employee the
certificate or certificates representing such Common Units in the General Partner’s possession belonging to Employee, or, if the Common Units are held in book-entry form, then the General Partner shall remove the notations indicating that the
Common Units are subject to the restrictions of this Agreement. Employee (or the beneficiary or personal representative of Employee in the event of Employee’s death or disability, as the case may be) shall deliver to the General Partner
any representations or other documents or assurances as the General Partner or its representatives deem necessary or advisable in connection with any such delivery. 

(f) As a condition to any accelerated vesting described herein, Employee must first execute within the time provided to do so (and not revoke
in any time provided to do so), a release, in a form acceptable to the General Partner, releasing the Committee, the Employer, the Partnership, the General Partner, their respective Affiliates, and their respective shareholders, members, partners,
officers, managers, directors, fiduciaries, employees, representatives, agents and benefit plans (and fiduciaries of such plans) from any and all claims, including any and all causes of action arising out of Employee’s employment with the
Employer and any of its Affiliates or the termination of such employment, but excluding all claims to payments under the Plan and this Agreement. 

4. Distributions. Distributions that are paid or distributed with respect to a Restricted Unit (whether in the form of Units or
other property (including cash)) shall be paid 

  
 Exhibit A-4 

 
and distributed to Employee at the same time distributions are made to the unitholders of the Partnership, regardless of whether the Restricted Units have become vested. Distributions paid or
distributed in the form of securities with respect to Restricted Units shall bear such legends, if any, as may be determined by the Committee from time to time to reflect the terms and conditions of this Agreement and to comply with applicable
securities laws. 
 5. Rights as Unitholder. Except as otherwise provided herein, upon issuance of the Restricted Units,
Employee shall have all the rights of a holder of Common Units with respect to such Restricted Units subject to the restrictions herein, including the right to vote the Common Units. 

6. Tax Withholding. Upon any taxable event arising in connection with the Restricted Units, the General Partner shall have the
authority and the right to deduct or withhold (or cause the Employer or one of its Affiliates to deduct or withhold), or to require Employee to remit to the General Partner (or the Employer or one of its Affiliates), an amount sufficient to satisfy
all applicable federal, state and local taxes required by law to be withheld with respect to such event. In satisfaction of the foregoing requirement, unless otherwise determined by the Committee, the General Partner or the Employer or one of its
Affiliates shall withhold, or cause to be surrendered, from any cash or equity remuneration (including any of the Common Units issued under this Agreement) then or thereafter payable to Employee an amount equal to the aggregate amount of taxes
required to be withheld with respect to such event. The amount of such withholding shall be limited to the aggregate amount of taxes required to be withheld based on the minimum statutory withholding rates for federal, state, local and foreign
income tax and payroll tax purposes that are applicable to such taxable income; provided, however, that such withholding may be based on rates in excess of the minimum statutory withholding rates if (x) the Committee (i) determines
that such withholding would not result in adverse accounting, tax or other consequences to the General Partner or any of its Affiliates (other than immaterial administrative, reporting or similar consequences) and (ii) authorizes such
withholding at such greater rates and (y) Employee consents to such withholding at such greater rates. Employee acknowledges and agrees that none of the Board, the Committee, the General Partner, the Partnership, the Employer or any of their
respective Affiliates has made any representation or warranty as to the tax consequences to Employee as a result of the receipt of the Restricted Units, the lapse of any Forfeiture Restrictions or the forfeiture of any of the Restricted Units
pursuant to the Forfeiture Restrictions. Employee represents that he is in no manner relying on the Board, the Committee, the Partnership, General Partner, the Employer or any of their respective Affiliates or any of their respective managers,
directors, officers, employees or authorized representatives (including, without limitation, attorneys, accountants, consultants, bankers, lenders, prospective lenders and financial representatives) for tax advice or an assessment of such tax
consequences. Employee represents that he has consulted with any tax consultants that Employee deems advisable in connection with the Restricted Units. 

7. Refusal to Transfer; Stop-Transfer Notices. The Partnership shall not be required (a) to transfer on its books any
Common Units that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (b) to treat as owner of such Common Units or to accord the right to vote or pay distributions to any purchaser or other
transferee to whom such Common Units shall have been so transferred. Employee agrees that, in order to ensure compliance with the restrictions referred to herein, the Partnership or the General 

  
 Exhibit A-5 

 
Partner may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Partnership transfers its own securities, it may make appropriate notations to
the same effect in its own records. 
 8. Restricted Units Not Transferable. Prior to becoming Earned Units, the
Restricted Units may not be (a) sold, pledged, assigned or transferred in any manner during the lifetime of Employee other than by will or the laws of descent and distribution, unless and until the Forfeiture Restrictions have lapsed, or
(b) liable for the debts, contracts or engagements of Employee or his or her successors in interest. Except to the extent expressly permitted by the preceding sentence, any purported sale, pledge, assignment, transfer, attachment or encumbrance
of the Restricted Units or any interest or right therein shall be null, void and unenforceable against the Partnership, the General Partner, the Employer and their respective Affiliates. 

9. Section 83(b) Election. If Employee makes an election under Section 83(b) of the Code to be taxed with respect to
the Restricted Units as of the Date of Grant rather than as of the date or dates upon which Employee would otherwise be taxable under Section 83(a) of the Code, Employee hereby agrees to (a) use the election form provided in Exhibit
B for such purpose and (b) deliver a copy of such election to the General Partner promptly after filing such election with the Internal Revenue Service. 

10. [Additional Restrictions. By accepting this Award, Employee expressly intends and agrees to be legally bound by the
Restrictive Covenants set forth in Articles III, IV and V of the Severance Agreement, the provisions of which are hereby incorporated by reference into this Agreement and shall be deemed a part of this Agreement for all purposes. Employee expressly
acknowledges and affirms that this Award further aligns Employee’s interests with the Employer’s long-term business interests and this Award would not be granted to Employee hereunder if Employee had not agreed to be bound by the
Restrictive Covenants. If Employee is deemed by the Committee to have breached any of the Restrictive Covenants, whether before or after the termination of Employee’s employment with the Employer, then notwithstanding any provision in this
Agreement, the Plan or the Grant Notice to the contrary, as of the date that such breach is deemed to have occurred, as determined by the Committee (the “Breach Date”): 

(a) If, as of the Breach Date, any of the Restricted Units remain unvested, Employee shall, for no consideration, immediately forfeit and
surrender to the Partnership 100% of such unvested Restricted Units held by Employee and all rights arising from such Restricted Units and from being a holder thereof; and 

(b) If, as of the Breach Date, any of the Restricted Units have become vested, Employee shall, for no consideration, immediately forfeit and
surrender to the Partnership 50% of such vested Common Units and all rights arising from such Restricted Units and from being a holder thereof (or, if such Common Units are no longer held by Employee, Employee shall immediately pay to the
Partnership an amount of cash equal to the Fair Market Value of such Common Units as of the date they became vested); provided, however, that except as otherwise determined by the Committee, Employee shall not be required to surrender or otherwise
repay any cash distributions previously paid to Employee with respect to the Restricted Units or Common Units issued to Employee hereunder.]1

 Exhibit A-6 

 11. No Right to Continued Employment or Awards. 

(a) For purposes of this Agreement, Employee shall be considered to be employed by the Employer as long as Employee remains an
“Employee” (as such term is defined in the Plan), or an employee of a corporation or other entity (or a parent or subsidiary of such corporation or other entity) assuming or substituting a new award for this Award. Without limiting the
scope of the preceding sentence, it is specifically provided that Employee shall be considered to have terminated employment at the time of the termination of the status of the entity or other organization that employs Employee as an
“Affiliate” of the General Partner. Nothing in the adoption of the Plan, nor the grant of the Restricted Units pursuant to the Grant Notice and this Agreement, shall confer upon Employee the right to continued employment by, or a continued
service relationship with, the Employer or any of its Affiliates, or any other entity, or affect in any way the right of the Employer or any such Affiliate, or any other entity to terminate such employment at any time. Unless otherwise provided in a
written employment agreement or by applicable law, Employee’s employment by the Employer, or any such Affiliate, or any other entity shall be on an at-will basis, and the employment relationship may be terminated at any time by either Employee
or the Employer, or any such Affiliate, or other entity for any reason whatsoever, with or without cause or notice. Any question as to whether and when there has been a termination of such employment, and the cause of such termination, shall be
determined by the Committee or its delegate, and such determination shall be final, conclusive and binding for all purposes. 
 (b) The
grant of the Restricted Units is a one-time Award and does not create any contractual or other right to receive a grant of Awards or benefits in lieu of Awards in the future. Future Awards will be at the sole discretion of the Committee. 

12. Notices. Any notices or other communications provided for in this Agreement shall be sufficient if in writing. In the case
of Employee, such notices or communications shall be effectively delivered if hand delivered to Employee at Employee’s principal place of employment or if sent by registered or certified mail to Employee at the last address Employee has filed
with the Employer. In the case of the Partnership or General Partner, such notices or communications shall be effectively delivered if sent by registered or certified mail to the General Partner at its principal executive offices. 

13. Agreement to Furnish Information. Employee agrees to furnish to the General Partner all information requested by the General
Partner to enable the General Partner or any of its Affiliates to comply with any reporting or other requirement imposed upon the General Partner or any of its Affiliates by or under any applicable statute or regulation. 

14. Entire Agreement; Amendment. This Agreement constitutes the entire agreement of the parties with regard to the subject
matter hereof, and contains all the covenants, 

  
 Exhibit A-7 

 
promises, representations, warranties and agreements between the parties with respect to the Restricted Units granted hereunder; provided, however, that the terms of this Agreement shall
not modify and shall be subject to the terms and conditions of [for Senior VPs: the Severance Agreement and any other] [for all others: any] employment and/or severance agreement between the Partnership, the General Partner, the
Employer or any of their respective Affiliates and Employee in effect as of the date a determination is to be made under this Agreement. Without limiting the scope of the preceding sentence, except as provided therein, all prior understandings and
agreements, if any, among the parties hereto relating to the subject matter hereof are hereby null and void and of no further force and effect. The Committee may, in its sole discretion, amend this Agreement from time to time in any manner that is
not inconsistent with the Plan; provided, however, that except as otherwise provided in the Plan or this Agreement, any such amendment that materially reduces the rights of Employee shall be effective only if it is in writing and
signed by both Employee and an authorized officer of the General Partner. 
 15. Governing Law. This Agreement shall be
governed by, and construed in accordance with, the laws of the State of Delaware, without regard to conflicts of law principles thereof. 

16. Successors and Assigns. The General Partner may assign any of its rights under this Agreement without Employee’s
consent. This Agreement will be binding upon and inure to the benefit of the successors and assigns of the General Partner. Subject to the restrictions on transfer set forth herein and in the Plan, this Agreement will be binding upon Employee and
Employee’s beneficiaries, executors, administrators and the person(s) to whom the Restricted Units may be transferred by will or the laws of descent or distribution. 

17. Clawback. Notwithstanding any provision in this Agreement or the Grant Notice to the contrary, to the extent required by
(a) applicable law, including, without limitation, the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, any Securities and Exchange Commission rule or any applicable securities exchange listing standards
and/or (b) any policy that may be adopted or amended by the Board from time to time, all Restricted Units granted hereunder shall be subject to forfeiture, repurchase, recoupment and/or cancellation to the extent necessary to comply with such
law(s) and/or policy. 
 18. Counterparts. The Grant Notice may be executed in one or more counterparts, each of which
shall be deemed an original and all of which together shall constitute one instrument. Delivery of an executed counterpart of the Grant Notice by facsimile or pdf attachment to electronic mail shall be effective as delivery of a manually executed
counterpart of the Grant Notice. 
 19. Severability. If a court of competent jurisdiction determines that any provision of
this Agreement is invalid or unenforceable, then the invalidity or unenforceability of such provision shall not affect the validity or enforceability of any other provision of this Agreement, and all other provisions shall remain in full force and
effect.
