 3. Administration. 

(a) General. The Plan shall be administered by the Committee. Subject to the terms of the Plan and applicable law, and in
addition to other express powers and authorizations conferred on the Committee by the Plan, the Committee shall have full power and authority to: (i) designate Participants; (ii) determine the type or types of Awards to be granted to a
Participant; (iii) determine the number of Units to be covered by Awards; (iv) determine the terms and conditions of any Award (including but not limited to performance requirements for such Award); (v) determine whether, to what
extent, and under what circumstances Awards may be 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, in its discretion, provide for the extension of the exercisability of an Award, accelerate the vesting or exercisability of an Award, eliminate or make less restrictive any
restrictions applicable to an Award, waive any restriction or other provision of this Plan or an Award or otherwise amend or modify an Award or Award Agreement in any manner that is compliant with or exempt from the requirements of Section 409A
of the Code and is either (i) not materially adverse to the Participant to whom such Award was granted or (ii) consented to by such Participant. 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 Company,
the Partnership, any Affiliate, any Participant, and any beneficiary of any Award. No member of the Committee or officer of the Company to whom the Committee has delegated authority in accordance with the provisions of Section 3(b) of this Plan
shall be liable for anything done or omitted to be done by him or her, by any member of the Committee or by any officer of the Company in connection with the performance of any duties under this Plan, except for his or her own willful misconduct.

 (b) Delegation. The Board or the Committee may authorize a committee of one or more members of the Board to grant
individual Awards pursuant to such conditions or limitations as the Board or the Committee may establish. The Committee may also delegate to the Chief Executive Officer and to other employees of the Company (i) the authority to grant individual

 4. Units. 

(a) Limits on Units Deliverable. Subject to adjustment as provided in Section 4(c), the maximum number of Units that may be
delivered or reserved for delivery or underlying Awards in the aggregate issued under the Plan is
                        . If any Award expires, is canceled, exercised, paid or otherwise terminates without the delivery
of Units, then the Units covered by such Award, to the extent of such expiration, cancellation, exercise, payment or termination, shall again be Units with respect to which Awards may be granted. Units that are delivered by a Participant in
satisfaction of the exercise or other purchase price of an Award or the tax withholding obligations associated with an Award, are withheld to satisfy the Company’s tax withholding obligations or are not otherwise delivered to a Participant
pursuant to the international mobility policy (or similar arrangement) of the Company or its Affiliates are available for delivery pursuant to other Awards. The Committee may from time to time adopt and observe such rules and procedures concerning
the counting of Units against the Plan maximum or any sublimit as it may deem appropriate, including rules more restrictive than those set forth above to the extent necessary to satisfy the requirements of any national stock exchange on which the
Units are listed or any applicable regulatory requirement. The Board, the Committee and the appropriate officers of the Company are authorized to take from time to time whatever actions are necessary, and to file any required documents with
governmental authorities, stock exchanges and transaction reporting systems to ensure that Units are available for issuance pursuant to Awards. 

(b) Sources of Units Deliverable Under Awards. Any Units delivered pursuant to an Award shall consist, in whole or in part, of
Units acquired in the open market, common units already owned by the Company, common units acquired by the Company directly from the Partnership or any other person or any combination of the foregoing.  

(c) Adjustments. In the event that any distribution (whether in the form of cash, Units, other securities, or other property),
recapitalization, split, reverse split, reorganization, merger, 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, then the Committee shall, in such manner as it may deem equitable, adjust any or all of (i) the number and type of Units (or other securities or property)
with respect to which Awards may be granted, (ii) the number and type of Units (or other securities or property) subject to outstanding Awards, and (iii) the grant or exercise price with respect to any Award, or 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. No adjustment pursuant to this Section 4(c) shall be made in a manner that results in noncompliance with the
requirements of Section 409A of the Code, to the extent applicable. 
 5. Eligibility. 

Any Employee, Consultant or Director shall be eligible to be designated a Participant and receive an Award under the Plan.

 6. Awards. 

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 Company or any Affiliate. No substitution shall be made in a manner that results in noncompliance with the requirements of Section 409A of the Code, to the extent
applicable. Awards granted in addition to or in tandem with other Awards or awards granted under any other plan of the Company or any Affiliate may be granted either at the same time as or at a different time from the grant of such other Awards or
awards. 
 (a) Unrestricted Units. The Committee shall have the discretion to determine the Employees, Consultants and
Directors to whom unrestricted Units shall be granted and the number of Units to be granted. All unrestricted Units granted shall be fully vested upon grant and shall not be subject to forfeiture. 

(b) Restricted Units. The Committee shall have the authority to determine the Employees, Consultants and Directors to whom
Restricted Units shall be granted, the number of Restricted Units to be granted to each such Participant, the Restricted Period, the conditions under which the Restricted Units may become vested or forfeited, and such other terms and conditions as
the Committee may establish with respect to such Awards. To the extent provided by the Committee, in its discretion, 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, without interest, until the Restricted Unit vests or is forfeited with the accumulated distributions being paid or
forfeited at the same time, as the case may be. Absent such a restriction on the distributions in the Award Agreement, distributions during the Restricted Period shall be paid to the holder of the Restricted Unit without restriction. 

(c) Phantom Units. The Committee shall have the authority to determine the Employees, Consultants and Directors to whom Phantom
Units shall be granted, the number of Phantom Units to be granted to each such Participant, the Restricted Period, the time or conditions under which the Phantom Units may become vested or forfeited, which may include, without limitation, the
accelerated vesting upon the achievement of specified performance goals, and such other terms and conditions as the Committee may establish with respect to such Awards, including whether DERs are granted with respect to such Phantom Units. 

 (d) Options. The Committee shall have the authority to determine the Employees, Consultants and Directors to whom
Options shall be granted, the number of Units to be covered by each Option, whether DERs are granted with respect to such Option, the purchase price therefor and the conditions and limitations applicable to the exercise of the Option as the
Committee shall determine, that are not inconsistent with the provisions of the Plan. The term of an Option may not exceed 10 years. The purchase price per Unit purchasable under an Option shall be determined by the Committee at the time the
Option is granted, provided such purchase price may not be less than 100% of the Fair Market Value of a Unit as of the date of grant. The Committee shall determine the time or times at which an Option may be exercised in whole or in part, which may
include, without limitation, accelerated vesting upon the achievement of specified performance goals, and the method or methods by which payment of the exercise price  

  
 5 







 
with respect thereto may be made or deemed to have been made, which may include, without limitation, cash, check acceptable to the Company, a broker-assisted cashless exercise through procedures
approved by the Committee, delivery of previously owned Units having a Fair Market Value on the exercise date equal to the relevant exercise price, or any combination thereof. 

(e) Unit Appreciation Rights. The Committee shall have the authority to determine the Employees, Consultants and Directors to
whom Unit Appreciation Rights shall be granted, the number of Units to be covered by each grant and the conditions and limitations applicable to the exercise of the Unit Appreciation Right as the Committee shall determine, that are not inconsistent
with the provisions of the Plan. The exercise price per Unit Appreciation Right shall be not less than 100% of the Fair Market Value of a Unit as of the date of grant. The term of a Unit Appreciation Right may not exceed 10 years. 

(f) Distribution Equivalent Rights. 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 the DERs shall be paid directly to the Participant, be credited to a bookkeeping account (with or without interest in the discretion of the Committee) the vesting
restrictions and payment provisions applicable to the Award, and such other provisions or restrictions as determined by the Committee in its discretion all of which shall be specified in the Award Agreements. 

7. Limits on Transfer of Awards. 
 Each
Award shall be exercisable or payable only to the Participant during the Participant’s lifetime, or to the person to whom the Participant’s rights shall pass by will or the laws of descent and distribution. No Award and no right under any
such Award may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered by a Participant and any such purported assignment, alienation, pledge, attachment, sale, transfer or encumbrance shall be void and unenforceable
against the Company or any Affiliate. Notwithstanding the foregoing, to the extent specifically provided by the Committee with respect to an Award, an Award may be transferred by a Participant without consideration to immediate family members or
related family trusts, limited partnerships or similar entities or on such terms and conditions as the Committee may from time to time establish. 
 8.
Securities Restrictions. 
 (a) All certificates for Units or other securities of the Partnership delivered under the Plan pursuant to
any Award or the exercise thereof 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 stock exchange upon which
such Units or other securities are then listed, and any applicable federal or state laws, and the Committee may cause a legend or legends to be put on any such certificates to make appropriate reference to such restrictions. 

  
 6 







 (b) Notwithstanding anything in the Plan or any Award Agreement to the contrary, 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 Company is not reasonably able to obtain Units to deliver, or to otherwise deliver Units,
pursuant to such Award without violating the rules or regulations of any applicable law 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, without limitation, any exercise price or tax withholding) is received by the Company. 
 9.
Change of Control. 
 The effect, if any, of a change of control on outstanding Awards shall be set forth in the applicable Award
Agreement. 
 10. Amendment and Termination. 

Except as required by applicable law or the rules of the principal securities exchange on which the Units are traded, the Board 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 Participant, any other holder or beneficiary of an Award or any other Person.
Further, any amendment to the Plan must not violate the requirements of Section 409A of the Code (to the extent applicable) and must be (i) not materially adverse to any affected Participant or (ii) consented to by such Participant.

 11. 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. The Company or any Affiliate is authorized to withhold 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, other securities, or other property) of any applicable taxes payable at the minimum statutory rate in respect of
the grant of an Award, its exercise, the lapse of restrictions thereon, or any 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 Company or such Affiliate to satisfy its
withholding obligations for the payment of such taxes. If applicable, the Company or any Affiliate may also reduce any Award delivery by the amount of any hypothetical tax and/or social security tax consistent with the international mobility policy
(or similar arrangement) of the Company or its Affiliates. 
 (c) No Right to Employment or Services. The grant of an
Award shall not be construed as giving a Participant the right to be retained as an Employee, Consultant or Director, as applicable. Further, the Company or an Affiliate may at any time dismiss a Participant from employment or service at any time.
 
 (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.  

  
 7 







 (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 a\Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to
conform to the applicable laws, 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, the rules of the principal securities exchange on which the Units are then traded, or entitle the Partnership or an Affiliate to recover the same under Section 16(b) of the Exchange Act, and any payment tendered to the Company 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 Partnership, Company or any participating Affiliate and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Partnership, Company or any
Affiliate pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the Partnership, Company or any participating 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 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. 

 (i) Facility of Payment. Any amounts payable hereunder to any person under legal disability or who, in the judgment of
the Committee, is unable to properly manage his financial affairs, may be paid to the legal representative of such person, or may be applied for the benefit of such person in any manner which the Committee may select, and the Partnership, Company
and its Affiliates shall be relieved of any further liability for payment of such amounts. 
 (j) 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.  

(k) No Guarantee of Tax Consequences. None of the Board, the Partnership, the Company, any Affiliate nor the Committee makes any
commitment or guarantee that any federal, state or local tax treatment will apply or be available to any person participating or eligible to participate hereunder. 

(l) No Benefit Rights Conferred. Compensation received by a Participant pursuant to this Plan or any Award Agreement shall not
be taken into account in determining benefits under any pension, retirement, profit-sharing or welfare benefit plan. In addition, such compensation shall not be added to base pay or base salary for future salary purposes or be taken into
consideration when calculating any incentive compensation.

 12. Section 409A of the Code. 

(a) Awards made under this Plan are intended to comply with or be exempt from Section 409A of the Code, and ambiguous provisions hereof,
if any, shall be construed and interpreted in a manner consistent with such intent. No payment, benefit or consideration shall be substituted for an Award if such action would result in the imposition of taxes under Section 409A of the Code.
Notwithstanding anything in this Plan to the contrary, if any Plan provision or Award under this Plan would result in the imposition of an additional tax under Section 409A of the Code, that Plan provision or Award shall be reformed, to the
extent permissible under Section 409A of the Code, to avoid imposition of the additional tax, and no such action shall be deemed to adversely affect the Participant’s rights to an Award. 

(b) Unless the Committee provides otherwise in an Award Agreement, each DER, Restricted Unit or Phantom Unit (or portion thereof if the Award
is subject to a vesting schedule) shall be settled no later than the 15th day of the third month after the end of the first calendar year in which the Award (or such portion thereof) is no longer subject to a “substantial risk of
forfeiture” within the meaning of Section 409A of the Code. If the Committee determines that a DER, Restricted Unit or Phantom Unit is intended to be subject to Section 409A of the Code, the applicable Award Agreement shall include
terms that are designed to satisfy the requirements of Section 409A of the Code. 
 (c) If the Participant is identified by the Company
as a “specified employee” (as defined by the Company) on the date on which the Participant has a “separation from service” (as defined by the Company) other than due to death, any Award payable or settled on account of a
separation from service that is deferred compensation subject to Section 409A of the Code shall be paid or settled on the earliest of (1) the first business day following the expiration of six months from the Participant’s separation
from service, (2) the date of the Participant’s death, or (3) such earlier date as complies with the requirements of Section 409A of the Code. 

13. Clawback; Malus. 
 Notwithstanding any
other provisions in this Plan, any Award shall be subject to recovery or clawback by the Company under any clawback or malus policy adopted by the Company or its Affiliates or required by applicable law, whether before or after the date of grant of
the Award. 
 14. Term of the Plan. 

The Plan has been approved by the Board and the limited partners of the Partnership effective as of
                    , 20    . The Plan shall terminate on, and no Awards may be granted after, the earliest of the
date established by the Board or the Committee,                     , 20     (or such earlier date, if any,
required by the rules of the exchange on which Units are traded) or the date Units are no longer available for delivery pursuant to Awards under the Plan. 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 Committee 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.
