 SECTION 4. Units. 
  
 (a) Limits on Units Deliverable. Subject to adjustment as provided in Section 4(c), the number of
Units that may be delivered with respect to Awards under the Plan is [             (        )]. Units withheld from an Award to either satisfy the
Company’s or its Affiliates’ tax withholding obligations with respect to the Award or pay the exercise price of an Award shall be counted against the number of Units that may be delivered under the Plan and shall not be available for
future grants of Awards. If any Award is forfeited, cancelled, exercised, paid, or otherwise terminates or expires without the actual delivery of Units pursuant to such Award (for the avoidance of doubt, the grant of Restricted Units is not a
delivery of Units for this purpose unless and until such Restricted Units vest and any restrictions placed upon them under the Plan lapse), the Units subject to such Award shall again be available for Awards under the Plan. To the extent permitted
by applicable law and securities exchange rules, Substitute Awards and Units issued in assumption of, or in substitution for, any outstanding awards of any entity acquired in any form of combination by the Partnership or any Affiliate thereof shall
not be counted against the Units available for issuance pursuant to the Plan. 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 Units acquired in the open market, from the Partnership, any Affiliate thereof or any other Person, or Units otherwise issuable by the Partnership, or any combination of the
foregoing, as determined by the Committee in its discretion. 
  
 (c) Anti-dilution Adjustments. 
  
 (i) Equity Restructuring. With respect to any “equity restructuring” event that could result in an additional compensation expense to the Company 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 Units 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. With respect to any other similar event that would not result in an ASC Topic 718 accounting charge 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. 

 
 (ii) Other Changes in Capitalization.
In the event of any non-cash distribution, Unit split, combination or exchange of Units, merger, consolidation or distribution (other than normal cash distributions) of Partnership assets to unitholders, or any other change affecting the Units of
the Partnership, other than an “equity restructuring,” the Committee may make equitable adjustments, if any, to reflect such change with respect to (A) the aggregate number and kind of Units that may be issued under the Plan;
(B) the number and kind of Units 

  
 -6-

 
(or other securities or property) subject to outstanding Awards; (C) the terms and conditions of any outstanding Awards (including, without limitation, any applicable performance targets or
criteria with respect thereto); and (D) the grant or exercise price per Unit for any outstanding Awards under the Plan. 
  

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 and/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. Options
which are intended to comply with Treasury Regulation Section 1.409A-1(b)(5)(i)(A) and UARs which are intended to comply with Treasury Regulation Section 1.409A-1(b)(5)(i)(B) or, in each case, any successor regulation, may be granted only
if the requirements of Treasury Regulation Section 1.409A-1(b)(5)(iii), or any successor regulation, are satisfied. Options and UARs that are otherwise exempt from or compliant with Section 409A may be granted to any eligible Employee,
Consultant or Director. 
  
 (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 a Substitute Award, may not be less than the
Fair Market Value of a Unit as of the date of grant of the Option or UAR. 
  
 (ii) Time and Method of Exercise. The Committee shall determine the exercise terms and any applicable Restricted Period with respect to an Option or UAR, which may include, without limitation,
provisions for accelerated vesting upon the achievement of specified performance goals and/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, without limitation, cash, check acceptable to the Company, withholding Units having a Fair Market Value on the exercise date equal to the relevant exercise price from the Award, a “cashless” exercise through procedures
approved by the Company, or any combination of the foregoing methods. 
  
 (iii) Exercise of Options and UARs on Termination of Service. Each Option and UAR Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the Option or
UAR following a termination of the Participant’s Service. Unless otherwise determined by the Committee, if the Participant’s Service is terminated for Cause, the Participant’s right to exercise the Option or UAR shall

  
 -7-

 
terminate as of the start of business on the effective date of the Participant’s termination. To the extent the Option or UAR is not vested and exercisable as of the termination of Service,
the Option or UAR shall terminate when the Participant’s Service terminates. Subject to the foregoing, such provisions shall be determined in the sole discretion of the Committee, need not be uniform among all Options and UARs issued pursuant
to the Plan, and may reflect distinctions based on the reasons for termination of Service. 
  

(iv) Term of Options and UARs. The term of each Option and UAR shall be stated in the Award Agreement,
provided, that the term shall be no more than ten (10) years from the date of grant thereof. 
  

(v) Prohibition on Repricing. Subject to Section 4(c) and Section 7(c), the Committee shall not, without
the approval of the unitholders of the Partnership, (i) reduce the per Unit exercise price of any outstanding Option or UAR, (ii) cancel any Option or UAR in exchange for cash or another Award when the Option or UAR price per Unit exceeds
the Fair Market Value of the underlying Units, or (iii) otherwise reprice any Option or UAR. Subject to Sections 4(c), 7 and 8(e) hereof, the Committee shall have the authority, without the approval of the unitholders of the Partnership, to
amend any outstanding Award, to increase the exercise price per Unit, or to cancel and replace an Award with the grant of an Award having an exercise price per Unit that is greater than or equal to the exercise price per Unit of the original Award.

  
 (b) Restricted Units and Phantom Units.
The Committee shall have the authority to determine the Employees, Consultants and Directors to whom Restricted Units and/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, including, without limitation, restrictions on transferability, as the Committee may
establish with respect to such Awards. 
  
 (i) Payment of Phantom Units. The Committee shall specify, or permit the Participant to elect in accordance with the requirements of Section 409A, the conditions and dates or events upon which
the cash or Units underlying an award of Phantom Units shall be issued, which dates or events shall not be earlier than the date on which the Phantom Units vest and become nonforfeitable and which conditions and dates or events shall be subject to
compliance with Section 409A (unless the Phantom Units are exempt therefrom). 
  
 (ii) Vesting of Restricted Units. Upon or as soon as reasonably practicable following the vesting of each Restricted Unit, subject to satisfying the tax withholding obligations of
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) so that the Participant then holds an unrestricted Unit. 

 
 (c) DERs. The Committee shall have the authority to
determine the Employees, Consultants and/or Directors to whom DERs are granted, whether such DERs are tandem or 

  
 -8-

 
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), 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 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 and/or Phantom Units by such formula and at such time 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
tandem Award, or be subject to such other provisions or restrictions as determined by the Committee in its discretion. Notwithstanding the foregoing, DERs shall only be paid in a manner that is either exempt from or in compliance with
Section 409A. 
  
 (d) Unit Awards. Unit
Awards may be granted under the Plan (i) to such Employees, Consultants and/or Directors and in such amounts as the Committee, in its discretion, may select, and (ii) subject to such other terms and conditions, including, without
limitation, restrictions on transferability, as the Committee may establish with respect to such Awards. 
  

(e) Profits Interest Units. Any Restricted Unit award or Unit Award consisting of Profits Interest Units may only be issued to a
Participant for the performance of services to or for the benefit of the Partnership (i) in the Participant’s capacity as a partner of the Partnership, (ii) in anticipation of the Participant becoming a partner of the Partnership, or
(iii) as otherwise determined by the Committee, provided that the Profits Interest Units would constitute “profits interests” within the meaning of the Code, Treasury Regulations promulgated thereunder and any published guidance by
the Internal Revenue Service with respect thereto. At the time of grant, the Committee shall specify the date or dates on which the Profits Interest Units shall vest and become nonforfeitable, and may specify such conditions to vesting as it deems
appropriate. Profits Interest Units shall be subject to such restrictions on transferability and other restrictions as the Committee may impose. 
  

(f) Other Unit-Based Awards. Other Unit-Based Awards may be granted under the Plan to such Employees, Consultants and/or 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. Upon vesting, an Other Unit-Based Award may be paid in cash, Units (including Restricted Units) or any combination thereof as provided in the Award Agreement. 
  
 (g) Substitute Awards. Awards may be granted under the Plan in substitution of similar awards held by
individuals who become Employees, Consultants or Directors as a result of a merger, consolidation or acquisition by the Partnership or an Affiliate of another entity or the assets of another entity. 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 if such substitution complies with Section 409A and other applicable laws and securities exchange rules. 

  
 -9-

 (h) General. 

 
 (i) Forfeitures. Except as otherwise
provided in the terms of an Award Agreement, upon termination of a Participant’s Service for any reason during an applicable Restricted Period, all outstanding, unvested Awards held by such Participant shall be automatically forfeited by the
Participant. The Committee may, in its discretion, waive in whole or in part such forfeiture with respect to any such Award; provided, that any such waiver shall be effective only to the extent that such waiver will not cause any Award
intended to satisfy the requirements of Section 409A to fail to satisfy such requirements. 
  

(ii) 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 Company or any Affiliate. 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. 

 
 (iii) Limits on Transfer of Awards.

  
 (A) Except as provided in
paragraph (C) below, 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
paragraph (C) below, 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 Company, the Partnership or any Affiliate. 

 
 (C) The Committee may provide in an Award
Agreement 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, as applicable, or any other transferee specifically approved by the Committee after taking into account any state, federal, local or foreign tax and securities laws applicable to
transferable Awards. In addition, vested Units may be transferred to the extent permitted by the Partnership Agreement and not otherwise prohibited by the Award Agreement or any other agreement restricting the transfer of such Units. 

 
 (iv) Term of Awards. Subject to
Section 6(a)(iv) above, the term of each Award, if any, shall be for such period as may be determined by the Committee. 

  
 -10-

 (v) Unit Certificates. Unless otherwise determined by the Committee
or required by any applicable law, rule or regulation, neither the Company nor the Partnership shall deliver to any Participant certificates evidencing Units issued in connection with any Award and instead such Units shall be recorded in the books
of the Partnership (or, as applicable, its transfer agent or equity plan administrator). All certificates for Units or other securities of the Partnership delivered under the Plan and all Units issued pursuant to book entry procedures 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/or other requirements of the SEC, any securities 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 inscribed on any such certificates or book entry to make appropriate reference to such
restrictions. 
  
 (vi)
Consideration for Grants. To the extent permitted by applicable Law, Awards may be granted for such consideration, including services, as the Committee shall determine. 

 
 (vii) Delivery of Units or other
Securities and Payment by Participant of Consideration. Notwithstanding anything in the Plan or any Award Agreement to the contrary, subject to compliance with Section 409A, the Company 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 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 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 Company 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, without limitation,
any exercise price or tax withholding) is received by the Company.

benefits of a Participant with respect to an Award without the consent of such Participant.

regulations affecting the Plan or Awards hereunder, or any change in accounting principles affecting the financial statements of the Company or the Partnership, the Committee, in its sole discretion, without the consent of any Participant or holder
of an Award, and on such terms and conditions as it deems appropriate, may take any one or more of the following actions: 
  

(i) provide for either (A) the termination of any Award in exchange for a payment in an amount, if any, equal to the
amount that would have been attained upon the exercise of such Award or realization of the Participant’s rights under such Award (and, for the avoidance of doubt, if as of the date of the occurrence of such transaction or event, the Committee
determines in good faith that no amount would have been payable upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the Company without payment) or (B) the replacement of such
Award with other rights or property selected by the Committee in its sole discretion having an aggregate value not exceeding the amount that could have been attained upon the exercise of such Award or realization of the Participant’s rights had
such Award been currently exercisable or payable or fully vested; 
  
 (ii) provide that such Award be assumed by the successor or survivor entity, or a parent or subsidiary thereof, or be exchanged for similar options, rights or awards covering the equity of the successor
or survivor, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of equity interests and prices; 
  

(iii) make adjustments in the number and type of Units (or other securities or property) subject to outstanding Awards,
the number and kind of outstanding Awards, the terms and conditions of (including the exercise price), and/or the vesting and performance criteria included in, outstanding Awards; and 
  
 (iv) provide that such Award shall vest or become exercisable or payable, notwithstanding
anything to the contrary in the Plan or the applicable Award Agreement. 

  
 -12-

 Notwithstanding the foregoing, (i) with respect to an above event that constitutes an
“equity restructuring” that would be subject to a compensation expense pursuant ASC Topic 718, the provisions in Section 4(c) above shall control to the extent they are in conflict with the discretionary provisions of this
Section 7, provided, however, that nothing in this Section 7(c) or Section 4(c) above shall be construed as providing any Participant or any beneficiary of an Award any rights with respect to the “time value,”
“economic opportunity” or “intrinsic value” of an Award or limiting in any manner the Committee’s actions that may be taken with respect to an Award as set forth in this Section 7 or in Section 4(c) above; and
(ii) no action shall be taken under this Section 7 which shall cause an Award to fail to comply with Section 409A, to the extent applicable to 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 Company, the Company or any Affiliate thereof is authorized to deduct or 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 or Units, including Units that would otherwise be issued pursuant to such Award, or other property) of any applicable taxes payable in respect of an Award, including its grant,
its exercise, the lapse of restrictions thereon, or any payment or transfer thereunder or under the Plan, and to take such other action as may be necessary in the opinion of the Company 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 which may be so withheld or surrendered shall be limited to the number of Units which have a
Fair Market Value (which, in the case of a broker-assisted transaction, shall be determined by the Committee, consistent with applicable provisions of the Code) 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 supplemental taxable income. 

 
 (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 in the employ of the Company, the Partnership or any of their Affiliates, continue consulting services or to remain on the Board, as applicable. Furthermore, the
Company, the Partnership and/or an Affiliate thereof may at any time dismiss a Participant from employment or consulting 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 the Participant. 
  
 (d) No Rights as Unitholder. Except as otherwise provided herein, a Participant shall have none of the rights of a unitholder with respect to Units covered by any Award unless and until the
Participant becomes the record owner of such Units. 

  
 -13-

 (e) Section 409A. To the extent that the Committee determines that any Award
granted under the Plan is subject to Section 409A, the Award Agreement evidencing such Award shall include the terms and conditions required by Section 409A. To the extent applicable, the Plan and Award Agreements shall be interpreted in
accordance with Section 409A. Notwithstanding any provision of the Plan to the contrary, in the event that following the Effective Date (as defined in Section 9 below), the Committee determines that any Award may be subject to
Section 409A, the Committee may adopt such amendments to the Plan and the applicable Award Agreement, adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), and/or take any other actions
that the Committee determines are necessary or appropriate to preserve the intended tax treatment of the Award, including without limitation, actions intended to (i) exempt the Award from Section 409A, or (ii) comply with the
requirements of Section 409A ; provided, however, that nothing herein shall create any obligation on the part of the Committee, the Partnership, the Company or any of their Affiliates to adopt any such amendment, policy or procedure or
take any such other action, nor shall the Committee, the Partnership, the Company or any of their Affiliates have any liability for failing to do so. Notwithstanding any provision in the Plan to the contrary, the time of payment with respect to any
Award that is subject to Section 409A shall not be accelerated, except as permitted under Treasury Regulation Section 1.409A-3(j)(4). 
  

(f) Lock-Up Agreement. Each Participant shall agree, if so requested by the Company or the Partnership and any underwriter in
connection with any public offering of securities of the Partnership or any Affiliate, not to directly or indirectly offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option,
right or warrant for the sale of or otherwise dispose of or transfer any Units held by it for such period, not to exceed one hundred eighty (180) days following the effective date of the relevant registration statement filed under the
Securities Act in connection with such public offering, as such underwriter shall specify reasonably and in good faith. The Company or the Partnership may impose stop-transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such 180-day period. Notwithstanding the foregoing, the 180-day period may be extended for up to such number of additional days as is deemed necessary by such underwriter or the Company or Partnership to continue
coverage by research analysts in accordance with FINRA Rule 2711 or any successor rule. 
  
 (g) Compliance with Laws. The Plan, the granting and vesting of Awards under the Plan and the issuance and delivery of Units and the payment of money under the Plan or under Awards granted or
awarded hereunder are subject to compliance with all applicable federal, state, local and foreign laws, rules and regulations (including but not limited to state, federal and foreign securities law and margin requirements), the rules of any
securities exchange or automated quotation system on which the Units are listed, quoted or traded, and to such approvals by any listing, regulatory or governmental authority as may, in the opinion of counsel for the Company or the Partnership, be
necessary or advisable in connection therewith. Any securities delivered under the Plan shall be subject to such restrictions, and the Person acquiring such securities shall, if requested by the Company or the Partnership, provide such assurances
and representations to the Company or the Partnership as the Company or the Partnership may deem necessary or desirable to assure compliance with all applicable legal requirements. To the extent permitted by applicable law, the Plan and Awards
granted or awarded hereunder shall be 

  
 -14-

 
deemed amended to the extent necessary to conform to such laws, rules and regulations. In the event an Award is granted to or held by a Participant who is employed or providing services outside
the United States, the Committee may, in its sole discretion, modify the provisions of the Plan or of such Award as they pertain to such Participant to comply with applicable foreign law or to recognize differences in local law, currency or tax
policy. The Committee may also impose conditions on the grant, issuance, exercise, vesting, settlement or retention of Awards in order to comply with such foreign law and/or to minimize the Company’s or the Partnership’s obligations with
respect to tax equalization for Participants employed outside their home country. 
  
 (h) 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 conflicts of laws principles. 
  

(i) 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. 
  
 (j)
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. 
  
 (k) 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 Company, the Partnership or any of their Affiliates, on the one hand, and a Participant or any other Person on the other hand. To the extent that any Person acquires a right
to receive payments pursuant to an Award, such right shall be no greater than the right of any general unsecured creditor of the Partnership or any participating Affiliate of the Partnership. 
  
 (l) 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. 
  
 (m) 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. 

  
 -15-

 (n) No Guarantee of Tax Consequences. None of the Board, the Committee, the Company
or the Partnership 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 or local tax treatment will (or will not) apply or be available to
any Participant or other Person. 
  
 (o) Clawback;
Misconduct. To the extent required by applicable law or any applicable securities exchange listing standards, Awards and amounts paid or payable pursuant to or with respect to Awards shall be subject to clawback as determined by the Committee,
which clawback may include forfeiture, repurchase and/or recoupment of Awards and amounts paid or payable pursuant to or with respect to Awards. In addition, and without limiting the foregoing, except as otherwise provided by the Committee, if at
any time (including after a notice of exercise has been delivered or an award has vested) the Committee or any person designated by the Committee (each such person, an “Authorized Officer”) reasonably believes that a
Participant may have committed an Act of Misconduct as described in this Section 8(o), the Authorized Officer, the Committee or the Board may suspend the Participant’s rights to exercise or to vest in an Award, and/or to receive payment
for or receive Units in settlement of an Award pending a determination of whether an Act of Misconduct has been committed. 
  

If the Committee or an Authorized Officer determines that a Participant has committed an act of embezzlement, fraud, dishonesty,
nonpayment of any obligation owed to the Company or any Affiliate of the Company, breach of fiduciary duty, violation of ethics policy or code of conduct, or deliberate disregard of the Company’s or Affiliate of the Company’s rules
resulting in loss, damage or injury to the Company or any Affiliate of the Company, or if a Participant makes an unauthorized disclosure of any trade secret or confidential information, solicits any Employee or other service provider to leave the
employ or cease providing services to the Company or any Affiliate of the Company, breaches any intellectual property or assignment of inventions covenant, engages in any conduct constituting unfair competition, breaches any non-competition
agreement, induces any customer to breach a contract with the Company or any Affiliate of the Company or to cease doing business with the Company or any Affiliate of the Company, or induces any principal for whom the Company or any Affiliate of the
Company acts as agent to terminate such agency relationship (any of the foregoing acts, an “Act of Misconduct”), then except as otherwise provided by the Committee, (i) neither the Participant nor his or her estate nor
transferee shall be entitled to exercise any Option or Unit Appreciation Right whatsoever, vest in or have the restrictions on an Award lapse, or otherwise receive payment in respect of an Award, (ii) the Participant will forfeit all
outstanding Awards and (iii) the Participant may be required, at the Committee’s sole discretion, to return and/or repay to the Company or the Partnership any then vested Units previously granted under the Plan. In making such
determination, the Committee or an Authorized Officer may, in its discretion, give the Participant an opportunity to appear and present evidence on his or her behalf at a hearing before the Committee or its designee or an opportunity to submit
written comments, documents, information and arguments to be considered by the Committee. 
  
 (p) Facility Payment. Any amounts payable hereunder to any Person under legal disability or who, in the judgment of the Committee, is unable to manage properly his or her

  
 -16-

 
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 that the Committee may select, and the Partnership, the
Company and all of their Affiliates shall be relieved of any further liability for payment of such amounts. 
  

SECTION 9. Term of the Plan. 
  

The Plan shall be effective on the date on which the Plan is adopted by the Board (the “Effective
Date”) and shall continue until the earliest of (i) the date terminated by the Board, or (ii) the tenth (10th) anniversary of the date on which the Plan is adopted by the Board. However, any Award granted prior to such
termination, and the authority of the Board or 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. The Plan shall,
within twelve (12) months after the date of the Board’s initial adoption of the Plan, be submitted for approval by a majority of the outstanding Units of the Partnership entitled to vote.

 Exhibit 10.31 
 EMPLOYMENT AGREEMENT 
 This EMPLOYMENT AGREEMENT (this
“Agreement”), dated as of October 15, 2011, is entered into by and among Rentech Nitrogen GP, LLC, a Delaware limited liability company (the “Company”), and John A. Ambrose (“Executive”).

 RECITALS 
 A. Rentech Nitrogen Partners, L.P., a Delaware limited partnership (the “Partnership”), has filed a registration statement on Form S-1 (Registration No. 333-176065) (the
“Registration Statement”) relating to the offer and sale of common units representing limited partner interests in the Partnership (the “Common Units”); 

B. The Company is the general partner of the Partnership and, in connection with the Partnership’s initial public offering of the
Common Units pursuant to the Registration Statement (the “IPO”), Rentech Energy Midwest Corporation, a Delaware corporation (“REMC”), will become a wholly-owned subsidiary of the Partnership and the employees of
REMC will become employees of the Company and will cease to be employees of REMC; 
 C. Executive is currently employed by REMC
and is currently a party to that certain Change in Control Severance Benefits Agreement with REMC, dated August 1, 2010 (the “CIC Agreement”); 
 D. In connection with the Partnership’s IPO, the Company and Executive desire that the Company shall employ Executive and Executive shall accept such employment, beginning on the date of the first
closing (the “Closing”) of the sale of the Partnership’s Common Units pursuant to the Registration Statement (the “Effective Date”), subject to the terms and conditions set forth herein, and that this Agreement
shall supersede and replace in its entirety the CIC Agreement. 
 E. This Agreement shall become effective only if the Closing
occurs. 
 AGREEMENT 
 In consideration of the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

 1. Employment Period. Subject to the provisions for earlier termination herein, Executive’s employment under
this Agreement shall be for a period commencing on the Effective Date and ending on the second (2nd) anniversary of the Effective Date (the “Employment Period”), provided, however, that the Employment Period shall automatically renew for successive one (1)-year periods on
each anniversary of the Effective Date thereafter, unless either party provides the other party with written notice in accordance with Section 9 below of intent not to renew the Employment Period at least thirty (30) days prior to the end
of the initial Employment Period or any subsequent extension thereof. 
 2. Position and Duties. 

(a) Position. During the Employment Period, Executive shall serve as Chief Operating Officer of the Company. During the
Employment Period, Executive shall render 

 
such executive and managerial services to the Company as are consistent with Executive’s position and the by-laws of the Company and as the Company may from time to time reasonably
direct. Executive shall also serve for no additional compensation or remuneration, if requested by the Company, as an officer or director of such subsidiaries of the Company as may from time to time be designated by the Board of Directors of
the Company (the “Board”). 
 (b) Duties and Responsibilities. During the Employment Period, Executive
shall report to the President of the Company and shall devote his best efforts and his full business time and attention (except for permitted vacation periods and reasonable periods of illness or other incapacity) to the business and affairs of the
Company. Executive shall perform his duties, responsibilities and functions to the Company hereunder to the best of his abilities in a diligent, trustworthy, professional and efficient manner and shall comply with the Company’s policies
and procedures in all material respects. In performing his duties and exercising his authority under this Agreement, Executive shall support and implement the business and strategic plans approved from time to time by the Company and shall
support and cooperate with the Company’s efforts to operate in conformity with the business and strategic plans approved by the Company. During the Employment Period, Executive shall not serve as an officer or director of, or otherwise
perform services for compensation for, any other entity without the prior written consent of the Company’s Board of Directors (the “Board”). Nothing contained herein shall preclude Executive from (i) engaging in charitable
and community activities, (ii) participating in industry and trade organization activities, and (iii) managing his and his family’s personal investments and affairs, to the extent such activities do not, individually or in the
aggregate, materially interfere with Executive’s performance of his duties hereunder. 
 3. Compensation and Benefits. 

(a) Base Salary. During the Employment Period, the Company shall pay Executive a base salary of $210,300 per year (the
“Base Salary”), payable in regular installments in accordance with the Company’s ordinary payroll practices (in effect from time to time), but in any event no less frequently than monthly. Executive shall be eligible for an
annual review of his Base Salary based on performance as determined by the Board in its sole discretion. 

(b) Annual Bonus. For each fiscal year ending during the Employment Period, Executive will be eligible to earn
an annual bonus based on achievement of performance criteria established by the Board as soon as administratively practicable following the beginning of each such fiscal year (the “Annual Bonus”). The target amount (the
“Target Bonus”) of Executive’s Annual Bonus shall equal forty percent (40%) of Executive’s Base Salary (at the annual rate in effect at the start of the fiscal year), with a maximum Annual Bonus in an amount equal to
eighty percent (80%) of Executive’s Base Salary (at the annual rate in effect at the start of the fiscal year). For the avoidance of doubt, the amount of any Annual Bonus may be less than the Target Bonus (and may equal zero), as
determined in the sole discretion of the Board. The Company shall pay the Annual Bonus for each fiscal year (if any) after the end of the Company’s fiscal year in accordance with procedures established by the Board, but in no event later than
the fifteenth (15th) day of the third (3rd) month following the end of such fiscal year. To be eligible
for an Annual Bonus pursuant to this Section 3(b), Executive must be an employee of the Company on the last day of the relevant fiscal year. 
 (c) Expenses. During the Employment Period, the Company shall reimburse 

  
 2 

 
Executive for all reasonable business expenses incurred by him in the course of performing his duties and responsibilities under this Agreement in accordance with the Company’s policies in
effect from time to time for similarly situated executives with respect to travel, entertainment and other business expenses. 

(d) Other Benefits. Executive shall also be entitled to the following benefits during the Employment Period: 

(i) participation in the Company’s retirement plans, health and welfare plans, disability insurance plans and other benefit plans,
as in effect from time to time, in accordance with the terms of such plans and to the same extent and under the same conditions such participation and coverage are provided generally to similarly situated executives of the Company; 

(ii) coverage for services rendered to the Company and its Affiliates (as defined below) while Executive is a director or officer of the
Company or of any of its Affiliates, under the director and officer liability insurance policy(ies) maintained by the Company from time to time; and 
 (iii) paid vacation in accordance with the plans, programs and policies of the Company generally applicable to similarly situated executives of the Company. 

Nothing contained in this Section 3(d) shall, or shall be construed so as to, obligate the Company to adopt or maintain any plan,
program or policy at any time. 
 4. Termination of Employment. If Executive’s employment with the Company terminates for any
reason, the Company shall pay or provide to Executive: (i) Executive’s earned but unpaid Base Salary through the date of termination, (ii) Executive’s accrued but unpaid vacation time through the date of termination,
(iii) reimbursement of any business expenses incurred by Executive on or prior to the date of termination that are reimbursable under Section 3(c) above, and (iv) any vested amounts due to Executive under any plan, program or policy
of the Company (together, the “Accrued Obligations”). The Accrued Obligations described in clauses (i) – (iii) of the preceding sentence shall be paid within thirty (30) days after the date of termination (or
such earlier date as may be required by applicable law); the Accrued Obligations described in clause (iv) of the preceding sentence shall be paid in accordance with the terms of the governing plan or program. 

(a) Termination Without Cause or for Good Reason. In the event that Executive incurs a “separation from service” (within
the meaning of Section 409A (as defined below) (a “Separation from Service”) due to a termination of employment (i) by the Company without Cause (as defined below), or (ii) by Executive for Good Reason (as defined
below), then, in addition to the Accrued Obligations, subject to Executive’s timely execution and non-revocation of a release substantially in the form attached as Exhibit A (the “Release”) , Executive shall be
entitled to the benefits set forth below in this Section 4(a). Each payment under this Section 4(a) shall be treated as a separate payment for purposes of Section 409A. 

(i) The Company shall pay Executive an amount equal to twelve (12) months of Executive’s Base Salary (as in
effect on the date of Executive’s termination), payable in substantially equal installments in accordance with the Company’s normal payroll procedures during the period commencing on the date of termination and ending on the twelve
(12)-month anniversary of the date of 

  
 3 

 
termination; provided, that no payments under this Section 4(a)(i) shall be made prior to the first payroll date occurring on or after the thirtieth (30th) day following the date of termination (such payroll date, the
“First Payroll Date”) (with amounts otherwise payable prior to the First Payroll Date paid on the First Payroll Date without interest thereon). 

(ii) The Company shall pay Executive an amount equal to Executive’s Target Bonus for the year in
which the date of termination occurs, payable in a single lump-sum payment on the date on which annual bonuses are paid to the Company’s senior executives generally for such fiscal year, but in no event prior to the First Payroll Date or later
than the fifteenth (15th) day of the third (3rd) month following the end of the fiscal year in which the date
of termination occurs. 
 (iii) Executive shall be entitled to receive benefits mandated under Section 4980B
of the Code, as amended (“COBRA”) or any replacement or successor provision of United States tax law, subject to Executive’s valid election to receive COBRA benefits, at the same levels as in effect for Executive and
Executive’s dependents immediately prior to Executive’s termination of employment, with the premium paid at the Company’s expense until the first to occur of (A) twelve (12) months from the date of termination, (B) the
expiration of the period of time during which Executive is entitled to continuation coverage under the Company’s group health plan under COBRA, or (C) such date that Executive becomes eligible for coverage under the group health plan of
another employer (in any case, the “Continuation Period”), provided, that if (I) any plan pursuant to which such benefits are provided is not, or ceases prior to the expiration of the Continuation Period to be, exempt
from the application of Section 409A under Treasury Regulation Section 1.409A-1(a)(5), (II) the Company cannot provide the benefit without violating applicable law (including, without limitation, Section 2716 of the Public Health
Service Act), or (III) the Company is otherwise unable to continue to cover Executive or Executive’s dependents under its group health plans, then, in any such case, an amount equal to each remaining premium payment shall thereafter be paid to
Executive as currently taxable compensation in substantially equal monthly installments over the Continuation Period (or the remaining portion thereof) . After the Continuation Period, any COBRA continuation (to the extent permitted under applicable
law) shall be at Executive’s sole expense. 
 (b) Non-Renewal. In the event that Executive incurs a Separation from
Service as a result of the Company electing not to renew the Agreement in accordance with Section 1 above on terms and conditions substantially similar to those contained herein and, at the time of such non-renewal, Executive is willing and
able to continue providing services on terms and conditions substantially similar to those contained in this Agreement, then, subject to Executive’s timely execution and non-revocation of a Release substantially in the form attached as
Exhibit A, (i) the Company shall pay Executive an amount equal to twelve (12) months of Executive’s Base Salary (as in effect on the date of Executive’s termination), which amount shall, subject to Section 19 below,
be paid in substantially equal installments over a period of twelve (12) months from Executive’s Separation from Service in accordance with the payroll practices of the Company in effect from time to time (with the first such payment
occurring on the First Payroll Date and any amounts otherwise payable prior to the First Payroll Date paid instead on the First Payroll Date without interest thereon), and (ii) if Executive has not already been awarded an Annual Bonus in
respect of the fiscal year 

  
 4 

 
immediately preceding such non-renewal, the Company may, in its sole discretion, award some portion of an Annual Bonus to Executive in respect of such fiscal year based on Executive’s
service and the attainment of applicable performance objectives during such fiscal year. Each payment under this Section 4(b) shall be treated as a separate payment for purposes of Section 409A. 

(c) Other Terminations. In the event that Executive’s employment with the Company is terminated for any reason not described
in Section 4(a) or Section 4(b) above (including, but not limited to, a termination due to Executive’s death or disability, a termination for Cause or due to Executive’s resignation without Good Reason or Executive’s
election not to renew the Employment Period, in any case), the Company shall pay to Executive the Accrued Obligations in accordance with Section 4(a) above. 
 (d) No Other Payments. Except as expressly provided in Sections 4(a) and (b) above, upon Executive’s termination of employment with the Company, Executive shall have no rights to any
payments or benefits in connection with Executive’s employment with the Company or the termination thereof, including without limitation, rights to any salary, bonuses, employee benefits or other compensation which would have accrued or become
payable after the termination or expiration of the Employment Period, other than those expressly required under applicable law (e.g., COBRA). In the event of a termination of Executive’s employment with the Company, Executive’s sole and
exclusive remedy shall be to receive the payments and benefits described in this Section 4. 
 (e) Resignation as
Director and Officer. Effective as of the date of termination of Executive’s employment with the Company for any reason, Executive shall be deemed to have resigned from all offices and directorships, if any, then held with the Company or
any of its Affiliates. At the Company’s request, Executive shall execute and deliver such documentation as the Company may prescribe in order to effectuate such resignation(s). 

(f) Return of Company Property. Executive hereby agrees to return to the Company, no later than the date of termination, all
Company files, Company confidential or proprietary information (in any form contained, including any copies thereof), access keys, desk keys, identity badges, computers, electronic devices, telephones and credit cards, and such other property of the
Company as may be in Executive’s possession.

shall have the following meanings:

more intermediaries controls, is controlled by or is under common control with, the Person in question. As used herein, the term “control” means the possession, direct or indirect, of the power to direct or cause the direction of the
management and policies of a Person, whether through ownership of voting securities, by contract or otherwise. 
 (ii)
“Cause” shall mean one or more of the following: 
 (A) any material failure by Executive to

(B) any act of fraud, embezzlement, theft or misappropriation by Executive relating to the Company or its business or
assets; 
 (C) Executive’s commission of a felony or a crime involving moral turpitude; 

(D) any gross negligence or intentional misconduct on the part of Executive in the conduct of Executive’s duties and
responsibilities with the Company or which adversely affects the image, reputation or business of the Company or its Affiliates; or 
 (E) any material breach by Executive of any agreement between the Company and Executive. 
 (iii) “Good Reason” shall mean Executive’s resignation from employment with the Company as a result of one or more of the following: 

(A) a material reduction in Executive’s Base Salary, unless such reduction in Base Salary is part of a general
decrease in the base salary of similarly affected employees as part of a general cost reduction exercise; 
 (B)
a material reduction in Executive’s job duties and responsibilities or the assignment to Executive of any duties inconsistent in any material respect with Executive’s position with the Company; or 

(C) a material change in the geographic location at which Executive must perform services to the Company; provided,
that in no event will a relocation to a location within a fifty (50) mile radius of Executive’s principal work location as of the Effective Date be deemed material for purposes of this clause. 

For the avoidance of doubt, Executive’s voluntary resignation or retirement shall not constitute Good Reason. Notwithstanding the
foregoing, Executive’s resignation for Good Reason shall not be effective unless and until (i) Executive has first provided the Company with written notice specifically identifying the acts or omissions constituting the grounds for Good
Reason within thirty (30) days after the occurrence thereof, (ii) the Company has not cured such acts or omissions within thirty (30) days of its actual receipt of such notice, and (iii) the effective date of Executive’s
termination for Good Reason occurs no later than ninety (90) days after the initial existence of the facts or circumstances constituting Good Reason. 
 5. Confidentiality; Non-Competition; Non-Solicitation; Non-Disparagement. The Company and Executive acknowledge and agree that Executive’s agreement to enter into and adhere to the
confidentiality, non-competition, non-solicitation and non-disparagement provisions contained in this Section 5 constitutes a material inducement for the Company to enter into this Agreement, and is necessary to protect the goodwill of the
Company and its Affiliates, which include, without limitation, the Partnership and Rentech Inc., a Delaware corporation (“Rentech”). 

  
 6 

 (a) Confidentiality. Executive acknowledges and agrees that Executive is bound by the
terms of an Employee Agreement Regarding Ownership of Ideas and Nondisclosure entered into for the benefit of Rentech and its Affiliates (together with any other agreements protecting the confidential information of Rentech, REMC and/or their
Affiliates, the “Confidentiality Agreement”) and that nothing contained herein shall limit in any way Executive’s obligations under the Confidentiality Agreement. 

(b) Non-Competition. Executive acknowledges that: (i) the Company currently sells products and/or otherwise conducts business
in each of the States of Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Nebraska, Ohio, South Dakota and Wisconsin; and (ii) Executive has access to the trade secrets and other Confidential Information of the Company, Rentech, the
Partnership and their Affiliates. In order to protect the interests of the Company and its Affiliates in the goodwill of the Company and the trade secrets and Confidential Information of the Company and its Affiliates, during the Employment Period
and for a period of one (1) year after Executive’s termination of employment with the Company and its Affiliates for any reason (the “Restricted Period”), Executive shall not, anywhere in the States of Illinois, Indiana,
Iowa, Michigan, Minnesota, Missouri, Nebraska, Ohio, South Dakota and Wisconsin, or any other location in which the Company conducts business during Executive’s employment with the Company (such locations, together, the “Restricted
Territory”), directly or indirectly, without the prior written consent of the Company, perform services for, with or without pay, or have a financial interest of any kind in, any business, individual, partner, firm, corporation, or other
entity, whether as an employee, officer, director, consultant, owner, manager, operator, stockholder, member, partner, lender or otherwise, that is then a Competitor. For purposes of this Agreement, a “Competitor” is any person or
entity engaged in or planning to engage in the Business. For purposes of this Agreement, the “Business” means the business of producing, selling, distributing and/or marketing nitrogen-based products and by-products, including,
without limitation, ammonia, urea ammonium nitrate solution, liquid or granular urea, nitric acid, carbon dioxide and diesel-exhaust fluid. Executive and the Company acknowledge and agree that the terms set forth in this Section 5(b) shall
apply in each county of the State of Illinois and in the entire Restricted Territory. 
 Notwithstanding the foregoing, the
“beneficial ownership” by Executive, either individually or as a member of a “group,” as such terms are used in Regulation 13D of the General Rules and Regulations under the Exchange Act, of not more than one percent
(1%) of the voting stock of any publicly-held corporation shall not alone constitute a violation of this Agreement. 
 (c)
Non-Solicitation of Customers, Suppliers and Service Providers. During the Restricted Period, Executive shall not, directly or indirectly, solicit or influence or attempt to solicit or influence any customers, suppliers or service providers
of the Company and/or its Affiliates to terminate or limit their relationship with the Company and/or its Affiliates as customers, suppliers or service providers to the Company or to divert their purchases, sales, supplies or other activities with
respect to the Business to any Competitor. 
 (d) Non-Solicitation of Employees. Executive recognizes that Executive
possesses and will possess Confidential Information about the employees of the Company and its Affiliates relating to their education, experience, skills, abilities, compensation and benefits, and inter-personal relationships with customers of the
Company or its Affiliates. Executive recognizes that the information that Executive possesses and will possess about 

  
 7 

 
these employees is not generally known, is of substantial value to the Company and its Affiliates in developing their business and in securing and retaining customers, and has been and will be
acquired by Executive because of Executive’s position with the Company and its Affiliates. Executive agrees that, during the Restricted Period, Executive will not solicit, directly or indirectly, any employees or independent contractors of the
Company and its Affiliates to terminate or limit their relationship as employees or independent contractors of the Company or its Affiliates, or to become employed by or provide services to any person or entity other than the Company or its
Affiliates for any reason and/or to perform services for a Competitor (as an employee, independent contractor or otherwise). 

(e) Non-Disparagement. Executive agrees that during the Employment Period and thereafter, Executive will not make any statement,
publicly or privately, to any individual or entity, including, without limitation, clients, customers, employees, financial or credit institutions, which could reasonably be expected to disparage the Company, any of its Affiliates or any of their
respective employees, officers or directors. 
 (f) Injunctive Relief. It is expressly agreed that the Company and its
Affiliates will or would suffer irreparable injury if Executive were to breach any of the provisions of this Section 5 and that the Company and its Affiliates would by reason of any such breach be entitled to injunctive relief in a court of
competent jurisdiction without the need to post a bond or other security and without the need to demonstrate special damages. The aforementioned injunctive relief is and shall be in addition to any other remedies that may be available to the Company
and its Affiliates under this Agreement or otherwise. 
 (g) Survival of Provisions. The obligations contained in this
Section 5 shall survive the termination or expiration of Executive’s employment with the Company, and shall be fully enforceable thereafter. If it is determined by a court of competent jurisdiction in any state that any restriction in this
Section 5 is excessive in duration or scope or is unreasonable or unenforceable under the laws of that state, it is the intention of the parties that such restriction may be modified or amended by the court to render it enforceable to the
maximum extent permitted by the law of that state. 
 (h) No Additional Obligations of Executive Excused. All of the
provisions of this Section 5 are in addition to any other written agreements on the subjects covered herein that Executive may have with the Company and its Affiliates, and are not meant to and do not excuse any additional obligations that
Executive may have under such agreements. 
 (i) Tolling for Periods of Breach. The Restricted Period shall be extended
for a period equal to any period during which Executive is in breach of this Section 5. 
 (j) Third-Party
Beneficiaries. The Company’s Affiliates, including, without limitation, the Partnership and Rentech, shall be third-party beneficiaries of this Section 5, and shall be entitled to enforce the provisions of this Section 5 against
Executive. 
 6. Transitional Inquiries. For a reasonable period of time following the date of Executive’s termination with the
Company, but in no event less than three (3) months following the date of termination, Executive agrees to be available to the Company to answer telephone inquiries related to the transition of Executive’s duties without payment of
additional compensation. Executive’s obligations pursuant to this Section 6 are a material inducement to the Company’s entering into this Agreement with Executive. 

  
 8 

 7. Executive’s Representations. Executive represents and agrees that Executive fully
understands Executive’s right to discuss all aspects of this Agreement with Executive’s private attorney, has been advised to do so by the Company, and that to the extent, if any, that Executive desired, Executive availed himself of such
right. Executive further represents that Executive has carefully read and fully understands all of the provisions of this Agreement, that Executive is competent to execute this Agreement, that Executive’s agreement to execute this Agreement has
not been obtained by any duress and that Executive freely and voluntarily enters into it, and that Executive has read this document in its entirety and fully understands the meaning, intent and consequences of this document. 

8. Employment At-Will. Subject to the termination and severance obligations provided for in Section 4 of this Agreement, Executive hereby
agrees that the Company may dismiss Executive and terminate Executive’s employment with the Company, with or without advance notice and without regard to (i) any general or specific policies (whether written or oral) of the Company
relating to the employment or termination of its employees, or (ii) any statements made to Executive, whether made orally or contained in any document, pertaining to Executive’s relationship with the Company, or (iii) the existence or
non-existence of Cause. Executive’s participation in any benefit plan or compensation arrangement will not give Executive any right or claim to any benefit hereunder except to the extent such right has become fixed under the express terms of
this Agreement. 
 9. Notices. All notices or communications hereunder shall be in writing, addressed as follows: 

To the Company: 
 General Counsel 
 Rentech, Inc. 

10877 Wilshire Blvd., Suite 600 
 Los Angeles, CA 90024 
 To Executive: 

To the address on file in the permanent records of the Company at the time of the notice. 

In the event the Company relocates its executive offices, the then-effective address shall be substituted for that set forth above. All
notices hereunder shall be conclusively deemed to be received and shall be effective (i) if sent by hand delivery, upon receipt; or (ii) if sent by electronic mail or facsimile, upon confirmation of receipt by the sender of such
transmission. 
 10. Effectiveness. This Agreement shall become effective on the Effective Date without further action by any party;
provided, that if the Closing does not occur within one hundred eighty (180) days of the date of this Agreement, then this Agreement shall be null and void and of no force or effect. 

11. Severability. In the event any provision or part of this Agreement is found to be invalid or unenforceable, only that particular provision or
part so found, and not the entire 

  
 9 

 
Agreement, will be inoperative. 
 12. Enforcement. Without in any way limiting any
light or remedy otherwise available to the Company, if Executive materially violates any provision of this Agreement or any other confidentiality, nondisclosure, noncompetition or similar agreement with the Company to which Executive is a party, and
such violation, if unintentional on the part of Executive, continues for a period of ten (10) days following receipt of written notice from the Company, any severance payments then or thereafter payable by the Company to Executive under
Section 4(a) or Section 4(b) above may be terminated forthwith and upon such election by the Company, the Company’s obligation to pay and Executive’s right to receive such amounts shall terminate and be of no further force or
effect. Executive’s obligations under this Agreement shall not be limited or affected by, and such obligations shall remain in full force and effect notwithstanding, the termination of any severance payments by the Company in accordance with
this Section 12. The Company’s exercise of its right to terminate such payments shall not be deemed to be an election of remedies by the Company and shall not in any manner modify, limit or preclude the Company from exercising any other
rights or seeking any other remedies available to it at law or in equity. 
 13. Complete Agreement. This Agreement, the Confidentiality
Agreement and any other documents expressly referred to herein embody the complete agreement and understanding among the parties hereto and supersede and preempt any prior understandings, agreements or representations by or among Executive and the
Company or any successor thereto, whether written or oral, which may have related to the subject matter hereof in any way (including, without limitation, the CIC Agreement). 
 14. No Strict Construction. The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction
shall be applied against any party. 
 15. Counterparts. This Agreement may be executed in separate counterparts, each of which is deemed
to be an original and all of which taken together constitute one and the same agreement. 
 16. Successors and Assigns. This Agreement
shall be binding upon and inure to the benefit of the beneficiaries, heirs and representatives of Executive and the successors and assigns of the Company (including without limitation, any successor due to reincorporation of the Company or formation
of a holding company). Executive may not assign Executive’s rights (except by will or the laws of descent and distribution) or delegate Executive’s duties or obligations hereunder. No payment to be made hereunder shall be subject to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or other charge. 
 17. Choice of Law. All issues and questions
concerning the construction, validity, enforcement and interpretation of this Agreement and the exhibits hereto shall be governed by, and construed in accordance with, the laws of the State of Illinois, without regard to the principles of conflicts
of laws thereof. 
 18. Amendment and Waiver. Except as provided in Section 19 below, the provisions of this Agreement may be
amended, modified or waived only with the prior written consent of the Company and Executive, and no course of conduct or course of dealing or failure or delay by any party hereto in enforcing or exercising any of the provisions of this Agreement

  
 10 

 
(including, without limitation, the Company’s right to terminate Executive’s employment and the Employment Period for Cause) shall affect the validity, binding effect or enforceability
of this Agreement or be deemed to be an implied waiver of any provision of this Agreement. 
 19. Internal Revenue Code
Section 409A. 
 (a) General. To the extent applicable, this Agreement shall be interpreted in accordance with
Section 409A of the Code and Department of Treasury regulations and other interpretative guidance issued thereunder, including without limitation any such regulations or other such guidance that may be issued after the Effective Date
(“Section 409A”). Notwithstanding any provision of this Agreement to the contrary, in the event that following the Effective Date, the Company determines in good faith that any compensation or benefits payable under this Agreement
may not be either exempt from or compliant with Section 409A, the Company shall consult with Executive and may adopt such amendments to this Agreement or adopt other policies or procedures (including amendments, policies and procedures with
retroactive effect), or take any other commercially reasonable actions necessary or appropriate to preserve the intended tax treatment of the compensation and benefits payable hereunder and/or to preserve the economic benefits of such compensation
and benefits, including actions intended to (i) exempt the compensation and benefits payable under this Agreement from Section 409A, and/or (ii) comply with the requirements of Section 409A; provided, that this
Section 19(a) does not, and shall not be construed so as to, create any obligation on the part of the Company to adopt any such amendments, policies or procedures or to take any other such actions or to indemnify the Executive for any failure
to do so. 
 (b) Specified Employee. Notwithstanding anything to the contrary in this Agreement, no compensation or
benefits, including without limitation any severance payment under Section 4 above, shall be paid to Executive during the six (6)-month period following his Separation from Service to the extent that the Company determines that Executive is a
“specified employee” at the time of such Separation from Service (within the meaning of Section 409A) and that paying such amounts at the time or times indicated in this Agreement would be a prohibited distribution under
Section 409A(a)(2)(b)(i) of the Code. If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such six (6)-month period (or such earlier date upon which such amount
can be paid under Section 409A without being subject to such additional taxes, including as a result of Executive’s death), the Company shall pay to Executive a lump-sum amount equal to the cumulative amount that would have otherwise been
payable to Executive during such six (6)-month period. The Company’s determination as to whether such six-month delay is required by this sub-paragraph shall be made in good faith by the Company after consultation between the Company and
Executive. 
 20. Insurance. The Company may, at its discretion, apply for and procure in its own name and for its own benefit life
and/or disability insurance on Executive in any amount or amounts considered advisable. Executive agrees to cooperate in any medical or other examination, supply any information and execute and deliver any applications or other instruments in
writing as may be reasonably necessary to obtain and constitute such insurance. 
 21. Withholding. Any payments made or benefits
provided to Executive under this Agreement shall be reduced by any applicable withholding taxes or other amounts required to be withheld by law or contract, except that to the extent that any such benefits are not paid to

  
 11 

 
Executive in cash or concurrently with cash payment sufficient to satisfy applicable withholding obligations, Executive shall remit to the Company the amount of any applicable withholding taxes
concurrently with the provision of such benefits. To the extent that any taxes may be payable by Executive for the benefits provided to Executive by this Agreement beyond those required to be withheld by the Company, Executive agrees to pay them
directly to the taxing authority and to indemnify and hold the Company and its Affiliates harmless for any tax claims or penalties, and associated attorneys’ fees and costs, resulting from any failure by Executive to make required payments.

 22. Arbitration. Except as provided in Section 5 above, any dispute or controversy arising under or in connection with this
Agreement (excluding any dispute or controversy arising under or in connection with Section 5 hereof) or otherwise in connection with Executive’s employment by the Company or the termination thereof that cannot be mutually resolved by the
parties to this Agreement and their respective advisors and representatives shall be settled exclusively by arbitration in Chicago, Illinois in accordance with the rules of the American Arbitration Association before one arbitrator of exemplary
qualifications and stature, who shall be selected jointly by an individual to be designated by the Company and an individual to be selected by Executive, or if such parties cannot agree on the selection of the arbitrator, such arbitrator shall be
selected by the American Arbitration Association. The Company will pay the direct costs and expenses of any such arbitration, including the fees and costs of the arbitrator; provided, however, that the arbitrator may award attorneys’ fees to
the prevailing party, if permitted by applicable law. For the avoidance of doubt, this Section 22 shall not apply to any dispute or controversy arising under or in connection with Section 5 of this Agreement, which disputes and
controversies shall be resolved in accordance with the terms set forth in Section 5. 
 23. Executive’s Cooperation. During the
Employment Period and thereafter, Executive shall cooperate with the Company and its Affiliates, upon the Company’s reasonable request, with respect to any internal investigation or administrative, regulatory or judicial proceeding involving
matters within the scope of Executive’s duties and responsibilities to the Company and its Affiliates during the Employment Period (including, without limitation, Executive being available to the Company upon reasonable notice for interviews
and factual investigations, appearing at the Company’s reasonable request to give testimony without requiring service of a subpoena or other legal process, and turning over to the Company all relevant Company documents which are or may come
into Executive’s possession during Executive’s employment with the Company); provided, that any such request by the Company shall not be unduly burdensome or unreasonably interfere with Executive’s personal schedule or ability
to engage in gainful employment. In the event the Company requires Executive’s cooperation in accordance with this Section 23, the Company shall reimburse Executive for reasonable out-of-pocket expenses (including travel, lodging and
meals) incurred by Executive in connection with such cooperation, subject to substantiation in accordance with applicable Company policy. In the event that the obligations under this Section 23 require more than twenty (20) hours of
Executive’s time after the termination of the Employment Period, the Company shall thereafter pay to Executive compensation at an hourly rate equal to the quotient of (a) the Base Salary applicable on the date of the termination of
Executive’s employment, divided by (b) 1,750. 
 24. Headings. The section headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. 

  
 12 

 25. No Third Party Beneficiaries. Except as expressly set forth in Section 5 above, nothing in
this Agreement, expressed or implied, is intended to or shall confer on any person, other than the parties and their respective successors and permitted assigns, any rights or remedies under or by reason of this Agreement.

 EXHIBIT A 

FORM OF RELEASE 
 In
further consideration of the promises and mutual obligations set forth in the Employment Agreement between John A. Ambrose (“Executive”) and Rentech Nitrogen GP, LLC (the “Company”), dated as of
                    , 2011 (the “Employment Agreement”), Executive hereby agrees as follows: 

1. Return of Property. Executive has complied in all respects with Section 4(f) (“Return of Property”) of the Employment Agreement
(as defined below). 
 2. General Release and Waiver of Claims. 
 (a) Release. In consideration of the payments and benefits provided to Executive under the Employment Agreement and after consultation with counsel, Executive, personally and on behalf of each of
Executive’s respective heirs, executors, administrators, representatives, agents, successors and assigns (collectively, the “Releasors”) hereby irrevocably and unconditionally releases and forever discharges the Company and its
subsidiaries and affiliates and each of their respective officers, employees, directors, and agents and all persons acting in concert with them or any of them (“Releasees”) from any and all claims, actions, causes of action, rights,
judgments, obligations, damages, demands, accountings or liabilities of whatever kind or character (collectively, “Claims”), including, without limitation, any Claims under any federal, state, local or foreign law, including without
limitation, the Age Discrimination in Employment Act, as amended, 29 U.S.C. § 621, et seq.; Title VII of the Civil Rights Act of 1964, as amended by the Civil Rights Act of 1991, 42 U.S.C. § 2000 et seq.; Equal Pay Act, as amended, 29
U.S.C. § 206(d); the Civil Rights Act of 1866, 42 U.S.C. § 1981; the Family and Medical Leave Act of 1993, 29 U.S.C. § 2601 et seq.; the Americans with Disabilities Act of 1990, 42 U.S.C. § 12101 et seq.; the False Claims Act ,
31 U.S.C. § 3729 et seq.; the Employee Retirement Income Security Act, as amended, 29 U.S.C. § 1001 et seq.; the Worker Adjustment and Retraining Notification Act, as amended, 29 U.S.C. § 2101 et seq. the Fair Labor Standards Act, 29
U.S.C. § 215 et seq., the Sarbanes-Oxley Act of 2002, that the Releasors had, have, may have, or in the future may possess, arising out of (i) Executive’s employment relationship with and service as an employee, officer or director of
the Company and/or its affiliates, and the termination of such relationship(s) or service, and (ii) any event, condition, circumstance or obligation that occurred, existed or arose on or prior to the date hereof; provided,
however, that Executive does not release, discharge or waive any rights to payments and benefits provided under Section 4(a) or 4(b) of the Employment Agreement, as applicable, that are contingent upon the execution by Executive of this
Agreement, any vested benefits, any rights to indemnification, or any rights as a shareholder of the Company. 
 THE EXECUTIVE
ACKNOWLEDGES THAT HE HAS BEEN ADVISED OF AND IS FAMILIAR WITH THE PROVISIONS OF CALIFORNIA CIVIL CODE SECTION 1542, WHICH PROVIDES AS FOLLOWS: 
 “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR 

 
AT THE TIME OF EXECUTING THE RELEASE, WHICH, IF KNOWN BY HIM OR HER, MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.” 

BEING AWARE OF SAID CODE SECTION, THE EXECUTIVE HEREBY EXPRESSLY WAIVES ANY RIGHTS HE MAY HAVE THEREUNDER, AS WELL AS UNDER ANY OTHER
STATUTES OR COMMON LAW PRINCIPLES OF SIMILAR EFFECT. 
 (b) Specific Release of ADEA Claims. In further consideration of
the payments and benefits provided to Executive under the Employment Agreement, the Releasors hereby unconditionally release and forever discharge the Releasees from any and all Claims that the Releasors may have as of the date Executive signs this
Agreement arising under the Federal Age Discrimination in Employment Act of 1967, as amended, and the applicable rules and regulations promulgated thereunder (“ADEA”). By signing this Agreement, Executive hereby acknowledges and
confirms the following: 
 (i) Executive was, and is hereby, advised by the Company in connection with his termination to consult with an
attorney of his choice prior to signing this Agreement and to have such attorney explain to Executive the terms of this Agreement, including, without limitation, the terms relating to Executive’s release of claims arising under ADEA, and
Executive has in fact consulted with an attorney; 
 (ii) Executive was given a period of not fewer than twenty-one (21) days to
consider the terms of this Agreement and to consult with an attorney of his choosing with respect thereto; 
 (iii) Executive knowingly
and voluntarily accepts the terms of this Agreement; 
 (iv) the payments and benefits provided to Executive in consideration of this
release are in addition to any amounts otherwise owed to Executive; and 
 (v) this Agreement is written in a manner designed to be
understood by Executive and he understands it. Executive also understands that he has seven (7) days following the date on which he signs this Agreement within which to revoke the release contained in this paragraph, by providing the Company a
written notice of his revocation of the release and waiver contained in this paragraph. 
 (c) No Assignment.
Executive represents and warrants that he has not assigned any of the Claims being released under this Agreement. 
 3. Proceedings.
Executive has not filed, and agrees not to initiate or cause to be initiated on his behalf, any complaint, charge, claim or proceeding against the Releasees before any local, state or federal agency, court or other body relating to any Claims
released under this Agreement, including without limitation, any Claims relating to his employment or the termination of his employment, (each, individually, a “Proceeding”), and agrees not to participate voluntarily in any
Proceeding. Notwithstanding the foregoing, Executive may bring to the attention of the United States Equal Employment Opportunity Commission (the “EEOC”) claims of discrimination. Executive waives any right he may have to benefit in
any manner from any relief (whether monetary or otherwise) arising out of any Proceeding. 

  
 A-2

 4. Remedies. In the event Executive initiates or voluntarily participates in any Proceeding, or if he
fails to abide by any of the terms of this Agreement or his post-termination obligations contained in the Employment Agreement, or if he revokes the ADEA release contained in Paragraph 2(b) of this Agreement within the seven (7)-day period provided
under Paragraph 2(b), the Company may, in addition to any other remedies it may have, reclaim any amounts paid to him under the severance provisions of the Employment Agreement or terminate any benefits or payments that are subsequently due under
the Employment Agreement, without waiving the release granted herein. The foregoing shall not apply to Executive’s bringing to the attention of the EEOC any claims of discrimination. Executive acknowledges and agrees that the remedy at law
available to the Company for breach of any of his post-termination obligations under the Employment Agreement or his obligations under Paragraphs 2 and 3 of this Agreement would be inadequate and that damages flowing from such a breach may not
readily be susceptible to being measured in monetary terms. Accordingly, Executive acknowledges, consents and agrees that, in addition to any other rights or remedies that the Company may have at law or in equity, the Company shall be entitled to
seek a temporary restraining order or a preliminary or permanent injunction, or both, without bond or other security, restraining Executive from breaching his post-termination obligations under the Employment Agreement or his obligations under
Paragraphs 2 and 3 of this Agreement. Such injunctive relief in any court shall be available to the Company, in lieu of, or prior to or pending determination in, any arbitration proceeding. 

Executive understands that by entering into this Agreement he will be limiting the availability of certain remedies that he may have
against the Company and limiting also his ability to pursue certain claims against the Company. 
 5. Severability Clause. In the event
any provision or part of this Agreement is found to be invalid or unenforceable, only that particular provision or part so found, and not the entire Agreement, will be inoperative. 
 6. Non-admission. Nothing contained in this Agreement will be deemed or construed as an admission of wrongdoing or liability on the part of the Company or any of its affiliates. 

7. Governing Law. All matters affecting this Agreement, including the validity thereof, are to be governed by, and interpreted and construed in
accordance with, the laws of the State of Illinois regardless of the law that might be applied under principles of conflicts of laws. 
 8.
Arbitration. Except as otherwise provided in Section 5 (“Confidentiality; Non-Competition; Non-Solicitation; Non-Disparagement”) or Section 22 (“Arbitration”) of the Employment Agreement, any dispute or
controversy arising under or in connection with this Agreement or otherwise in connection with Executive’s employment by the Company or the termination thereof that cannot be mutually resolved by the parties to this Agreement and their
respective advisors and representatives shall be settled exclusively by arbitration in Chicago, Illinois in accordance with the rules of the American Arbitration Association before one arbitrator of exemplary qualifications and stature, who shall be
selected jointly by an individual to be designated by the Company and an individual to be selected by Executive or, if such parties cannot agree on the selection of the arbitrator, the arbitrator shall be selected by the American Arbitration
Association. The Company will pay the direct costs and expenses of any such arbitration, including the fees and costs of the arbitrator; provided, however, that the arbitrator may award attorneys’ fees to the prevailing party, if
permitted by 

  
 A-3

 
applicable law. 
 9. Notices. All notices or communications hereunder shall be in
writing, addressed as follows: 
 To the Company: 

General Counsel 

Rentech, Inc.

CONTENTS, AND THAT HE HEREBY EXECUTES THE SAME AND MAKES THIS AGREEMENT AND THE RELEASE AND AGREEMENTS PROVIDED FOR HEREIN VOLUNTARILY AND OF HIS OWN FREE WILL. 
 IN WITNESS WHEREOF, Executive has executed this Release this      day of
                    20    .
