the Partnership Group for Losses under Section 2.1(a) or Section 2.1(b) to the extent that the aggregate amount of all such Losses are in excess of $10,000,000 (the “Cap Amount”). Additionally, Rentech shall

(c) NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, IN NO EVENT SHALL ANY PARTY’S INDEMNIFICATION OBLIGATION
HEREUNDER COVER OR INCLUDE CONSEQUENTIAL, INDIRECT, INCIDENTAL, PUNITIVE, EXEMPLARY, SPECIAL OR SIMILAR DAMAGES OR LOST PROFITS SUFFERED BY ANY OTHER PARTY ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT. 

Section 2.4 Indemnification Procedures. 

  
 6 

 (a) The Indemnified Party agrees that within a reasonable period of time
after it becomes aware of facts giving rise to a claim for indemnification under this Article II, it will provide notice thereof in writing to the Indemnifying Party, specifying the nature of and specific basis for such claim.

 (b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any
counterclaims with respect to) any claims brought against the Indemnified Party by any Person (other than a Party) that are covered by the indemnification under this Article II, including, without limitation, the selection of counsel,
determination of whether to appeal any decision of any court and the settling of any such claim or any matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent of the Indemnified
Party unless it includes a full release of the Indemnified Party from such claim. 
 (c) The Indemnified Party
agrees to cooperate in good faith and in a commercially reasonable manner with the Indemnifying Party, with respect to all aspects of the defense of any claims covered by the indemnification under this Article II, including, without
limitation, the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense,
the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party that the Indemnifying Party considers relevant to such defense, the making available to the Indemnifying Party of any employees of the
Indemnified Party and the granting to the Indemnifying Party of reasonable access rights to the properties and facilities of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable
efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records and other information furnished by the Indemnified Party pursuant to this
Section 2.4. In no event shall the obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the immediately preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire
and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article II; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for
counsel in connection with any such defense. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control
over such defense. 
 (d) In determining the amount of any Loss for which the Indemnified Party is entitled to
indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party, and such correlative insurance benefit shall be net of any incremental insurance
premium that becomes due and payable by the Indemnified Party as a result of such claim and (ii) all amounts recovered by the Indemnified Party under contractual indemnities from third Persons.

other members of the Partnership Group, acknowledge and agree that their use of the Rentech Marks shall not create any right, title or interest in or to any of the Rentech Marks, and all use of the Rentech Marks by the General Partner, the
Partnership or any other member of the Partnership Group, shall inure solely to the benefit of Rentech. The General Partner and the Partnership, on behalf of itself and the other members of the Partnership Group, acknowledge and agree that they

it has any ownership in the Rentech Marks or registrations thereof, except such right and license granted by Rentech in Section 3.1. 
 Section 3.3 Quality Control. The General Partner and the Partnership agree, and agree to cause the other members of the Partnership Group, to use the Rentech Marks in accordance with such quality
standards and instructions established and communicated by Rentech from time to time. The General Partner and the Partnership Group shall at all times indicate that the Rentech Marks are registered and/or unregistered trademarks or logos of Rentech
and are being used by the General Partner and the Partnership Group pursuant to a license granted by Rentech. The General Partner and the Partnership Group shall not use the Rentech Marks in any manner which disparages Rentech or its reputation, nor
take any action or fail to take any necessary action which may jeopardize the Rentech Marks or Rentech’s ownership or control thereof. Rentech shall have, at all reasonable times and upon five (5) business days written notice to any of the
General Partner or the Partnership Group, the right to inspect such party’s use of the Rentech Marks and the associated services, products, marketing materials, and/or advertising in order to carry out appropriate quality control. Should
Rentech ever notify any of the General Partner or the Partnership Group that any use by such party of the Rentech Marks fails to comply with Rentech’s quality standards or instructions, such party shall promptly correct such defects in
accordance with reasonable instructions from Rentech with respect thereto. 
 Section 3.4 Indemnification. Rentech shall,
to the fullest extent permitted by applicable law, defend, indemnify and hold harmless the Partnership Group and its successors and assigns authorized hereunder and any of their respective officers, directors, employees, agents and representatives
from and against any and all Losses arising out of or related in any way to their use of the Rentech Marks in a manner in accordance with this Article III to the extent such claims are attributable to any claim of infringement or ownership
asserted by a third

party as to the Rentech Marks used in such manner. The Partnership Group shall, to the fullest extent permitted by applicable law, indemnify and hold harmless Rentech and its successors and
assigns authorized hereunder and any of their respective officers, directors, employees, agents and representatives from and against any and all Losses arising out of or related in any way to the Partnership Group’s use of the Rentech Marks in
a manner not in accordance with this Article III to the extent such claims are attributable to any claim of infringement or ownership asserted by a third party as to the Rentech Marks used in such manner. Rentech shall have the right to
control all aspects of the defense of (and any counterclaims with respect to) any claims asserted by a third party that are covered by the indemnification under this Section 3.4, including, without limitation, the selection of counsel,
determination of whether to appeal any decision of any court and the settling of any such claim or any matter or any issues relating thereto; provided, however, that where such claim is against the Partnership Group, no such settlement shall be
entered into without the consent of the Partnership Group unless it includes a full release of the Partnership Group from such claim. 
 Section 3.5 Termination. The provisions of this Article III may be terminated by Rentech upon a Partnership Change of Control, and concurrently with such termination the General Partner and
the Partnership shall (a) cease all use of the Rentech Marks and shall adopt new trademarks, service marks, and trade names that are not confusingly similar to the Rentech Marks and (b) no later than ninety (90) days following the
termination of this Article III, the General Partner shall have caused each member of the Partnership Group to change its legal name so that there is no longer any reference therein to the name “Rentech” or any variation, derivation
or abbreviation thereof, and in connection therewith, the General Partner shall cause each member of the Partnership Group to make all necessary filings of certificates to amend its Organizational Documents or otherwise change its legal name by such
date.

 Section 4.2 Effect of Waiver or Consent. Except as otherwise provided in this Agreement, a waiver or consent, express
or implied, to or of any breach or default by any Party in the performance by that Party of its obligations under this Agreement is not a consent or waiver to or of any other breach or default in the performance by that Party of the same or any
other obligations of that Party under this Agreement. Except as otherwise provided in this Agreement, failure on the part of a Party to complain of any act of another Party or to declare another Party in default under this Agreement, irrespective of
how long that failure continues, does not constitute a waiver by that Party of its rights with respect to that default until the applicable statute-of-limitations period has run. 

Section 4.3 Headings; References; Interpretation. All Article and Section headings in this Agreement are for convenience only and
will not be deemed to control or affect the meaning or construction of any of the provisions hereof. The words “hereof,” “herein” and “hereunder” and words of similar import, when used in this Agreement, will refer to
this Agreement as a whole, and not to any particular provision of this Agreement. All references herein to Articles and Sections will, unless the context requires a different construction, be deemed to be references to the Articles and Sections of
this Agreement, respectively. All personal pronouns used in this Agreement, whether used in the masculine, feminine or neuter gender, will include all other genders, and the singular will include the plural and vice versa. The terms
“include,” “includes,” “including” or words of like import will be deemed to be followed by the words “without limitation.” 
 Section 4.4 Assignment. Except as expressly provided herein, no Party shall have the right to assign its rights or obligations under this Agreement without the consent of the other Parties hereto.

 Section 4.5 Successors and Assigns. This Agreement will be binding upon and inure to the benefit of the Parties and
their respective successors and permitted assigns. 
 Section 4.6 Third Party Rights. Each Indemnified Party that is not
a Party shall be entitled to assert rights and remedies hereunder as a third-party beneficiary hereto with respect to the provisions of this Agreement affording a right, benefit or privilege to such Indemnified Party. Except as provided in the
preceding sentence, the provisions of this Agreement are intended to bind the Parties signatory hereto as to each other and are not intended to and do not create rights in any other Person or confer upon any other Person any benefits, rights or
remedies, and no Person is or is intended to be a third party beneficiary of any of the provisions of this Agreement. Without limiting the foregoing, no limited partner of the Partnership shall have the right, separate

  
 10 

 
and apart from the Partnership, to enforce any provision of this Agreement or to compel any Party to this Agreement to comply with the terms of this Agreement. 

Section 4.7 Counterparts. This Agreement may be executed in any number of counterparts, all of which together will constitute one
agreement binding on the Parties. 
 Section 4.8 Governing Law. THIS AGREEMENT IS GOVERNED BY AND SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES. 
 Section 4.9 Submission
to Jurisdiction; Waiver of Jury Trial. Each of the Parties hereby irrevocably acknowledges and consents that any legal action or proceeding brought with respect to any of the obligations arising under or relating to this Agreement may be brought
in the courts of the State of New York, or in the United States District Court for the Southern District of New York and each of the Parties hereby irrevocably submits to and accepts with regard to any such action or proceeding, for itself and in
respect of its property, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts. Each Party hereby further irrevocably waives any claim that any such courts lack jurisdiction over such Party, and agrees not to plead or
claim, in any legal action or proceeding with respect to this Agreement or the transactions contemplated hereby brought in any of the aforesaid courts, that any such court lacks jurisdiction over such Party. Each Party irrevocably consents to the
service of process in any such action or proceeding by the mailing of copies thereof by registered or certified mail, postage prepaid, to such Party, at its address for notices set forth in this Agreement, such service to become effective ten
(10) days after such mailing. Each Party hereby irrevocably waives any objection to such service of process and further irrevocably waives and agrees not to plead or claim in any action or proceeding commenced hereunder or under any other
documents contemplated hereby that service of process was in any way invalid or ineffective. The foregoing shall not limit the rights of any Party to serve process in any other manner permitted by applicable law. The foregoing consents to
jurisdiction shall not constitute general consents to service of process in the State of New York for any purpose except as provided above and shall not be deemed to confer rights on any Person other than the respective Parties. Each of the Parties
hereby waives any right it may have under the laws of any jurisdiction to commence by publication any legal action or proceeding with respect this Agreement. To the fullest extent permitted by applicable law, each of the Parties hereby irrevocably
waives the objection which it may now or hereafter have to the laying of the venue of any suit, action or proceeding arising out of or relating to this Agreement in any of the courts referred to in this Section 4.9 and hereby further
irrevocably waives and agrees not to plead or claim that any such court is not a convenient forum for any such suit, action or proceeding. The Parties agree that any judgment obtained by any Party or its successors or assigns in any action, suit or
proceeding referred to above may, in the discretion of such Party (or its successors or assigns), be enforced in any jurisdiction, to the extent permitted by applicable law. The Parties agree that the remedy at law for any breach of this Agreement
may be inadequate and that should any dispute arise concerning any matter hereunder, this Agreement shall be enforceable in a court of equity by an injunction or a decree of specific performance. Such remedies shall, however, be cumulative and
nonexclusive, and shall be in addition to any other remedies which the Parties may have. Each Party hereby waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in respect of any litigation as between
the Parties directly or indirectly arising out of, 

  
 11 

 
under or in connection with this Agreement or the transactions contemplated hereby or disputes relating hereto. Each Party (a) certifies that no representative, agent or attorney of any
other Party has represented, expressly or otherwise, that such other Party would not, in the event of litigation, seek to enforce the foregoing waiver and (b) acknowledges that it and the other Parties have been induced to enter into this
Agreement by, among other things, the mutual waivers and certifications in this Section 4.9. 
 Section 4.10
Remedies to Prevailing Party. If any action at law or equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to reasonable attorneys’ fees, costs, and necessary disbursements in
addition to any other relief to which such party may be entitled. 
 Section 4.11 Severability. If any provision of this
Agreement or the application thereof to any Person or any circumstance is held invalid or unenforceable to any extent, the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected

 Exhibit A 

In October 2009, the EPA Region 5 issued a Notice and Finding of Violation pursuant to the Clean Air Act (“CAA”) related
to the number 1 nitric acid plant at the Operating Company’s facility in East Dubuque, Illinois. The notice alleges violations of the CAA’s New Source Performance Standard for nitric acid plants, Prevention of Significant Deterioration
requirements and Title V Permit Program requirements. The notice appears to be part of the Environmental Protection Agency’s Clean Air Act National Enforcement Priority for New Source Review/Prevention of Significant Deterioration related to
acid plants, which seeks to reduce emissions from acid plants through proceedings that result in the installation of new pollution control technology.
