HTIG, Rentech and the Company are sometimes referred to hereafter individually as a “Party” and collectively as “Parties.”

RECITALS:

          A.          The Company was formed on June 15, 2004 by the Members.  Each Member owns a fifty percent (50%) interest in the Company, and there are no other members in the Company.

          B.          HTIG and Rentech entered into an Operating Agreement for the Company dated as of June 15, 2004 (the “Operating Agreement”).  Capitalized terms used in this Agreement and not otherwise defined shall have the meanings specified in the Operating Agreement.

          C.          Pursuant to a license agreement dated June 15, 2004 (the “Rentech License”), Rentech licensed to the Company certain Intellectual Property (as defined in the Rentech License) (the “Rentech Technology”) on the terms and conditions of the Rentech License.

          D.          Pursuant to a license agreement dated June 15, 2004 (the “HTIG License”) HTIG licensed to the Company certain Intellectual Property (as defined in the HTIG License) (the “HTIG Technology”) on the terms and conditions of the HTIG License.

          E.          Pursuant to the Rentech License, the Company had the right to modify, adapt, update, develop upgrades for and otherwise create derivative works and improvements based on or related to the Rentech Technology (“Rentech Derivative Works”).  Pursuant to the HTIG License, the Company had the right to modify, adapt, update, develop upgrades for and otherwise create Derivative Works based on or related to the HTIG Technology (“HTIG Derivative Works”).

          F.          The Parties desire now to (i) terminate the Patent and Trademark License Agreements, the Contribution Agreement, the Services Agreement and the Operating Agreement (collectively, the “FTS Contracts”); (ii) dissolve the Company and distribute the Rentech Derivative Works and the HTIG Derivate Works (collectively, the “Derivative Works”) and all other assets of the Company to the Members on the terms and conditions of this Agreement; and (iii) release and discharge all claims among them with respect to the Company.

          NOW, THEREFORE, based on the foregoing facts, the Parties agree as follows:

          1.          Termination of FTS Contracts.  The Parties hereby agree that each of the Patent and Trademark License Agreements, the Operating Agreement, the Contribution Agreement and the Services Agreement are all terminated as of the Effective Date, provided, however, that the limitations on use and the requirements to return Confidential Information set forth in sections 10.1 and 10.2 of the Operating Agreement, sections 6.1 and 6.3 of the Services Agreement and section 5 of each of the Patent and Trademark License Agreements (collectively, the “Confidential Provisions”) shall survive such termination.

          2.          Distribution of Properties.  The Company does hereby convey, transfer, assign and distribute all of its assets as follows:

	
  
 
  	
  
          (a)          The   Company hereby assigns, transfers and conveys to Rentech all right, title and   interest in and to all Rentech Derivative Works, if any;
  
	
  
 
  	
  
 
  
	
  
 
  	
  
          (b)          The   Company hereby assigns, transfers and conveys to HTIG all right, title and   interest in and to all HTIG Derivative Works, if any; and
  
	
  
 
  	
  
 
  
	
  
 
  	
  
          (c)          The   Company hereby assigns, transfers and conveys to both Rentech and HTIG, as   co-owners, any and all other intellectual property rights (including, without   limitation, patents, copyrights, trademarks, service marks, applications for   the foregoing and trade secrets) (collectively, “Intellectual Property”), if   any, developed or owned by the Company which is not Rentech Technology, HTIG   Technology, Rentech Derivative Works or HTIG Derivative Works (collectively,   “Independent IP”).  The Parties   acknowledge and agree that there is no overlap or conflict between the   Independent IP and (i) the Rentech Technology and Rentech Derivative Works;   or (ii) the HTIG Technology and HTIG Derivative Works.  Rentech and HTIG agree to execute such   documents and take such other lawful acts as may be necessary to

permit   either Member to enforce, protect or otherwise use the Independent IP in any   jurisdiction where both co-owners must consent to the use of co-owned   intellectual property.
  
	
   
  	
  
 
  
	
  
 
  	
  
          (d)          Where   desirable or necessary to further effectuate sections 3(a)-(c) above, the   Company hereby agrees to execute, acknowledge and deliver to HTIG and/or   Rentech, as the case may be, such written instruments and perform such other   lawful acts as may be necessary, in the reasonable judgment of HTIG and/or   Rentech, to obtain, maintain and enforce letters patent, trademark   registrations, copyright registrations or similar governmental registrations   or designations on all such proprietary assets, and all reissues, renewals   and extensions thereof, to vest the entire right, title and interest thereto   in HTIG, Rentech or both, as the case may be.
  
	
  
 
  	
  
 
  
	
  
For the avoidance of doubt, any improvement (as   defined by the United States patent law) to a patent which is included in   either HTIG Technology or Rentech Technology shall be deemed an HTIG   Derivative Work or Rentech Derivative Work, respectively.  The categorization of Derivative Works as   Rentech Derivative Works or HTIG Derivative Works will depend solely the   underlying technology upon which it is based, and not upon any funding   provided to develop the applicable Derivative Works.  For example, the Parties acknowledge that   amounts spent with UOP to develop knowledge of producing fuels meeting ASTM   specifications from the intermediate products from the GTL reactor that were   specific to Rentech’s wax product will be deemed Rentech Derivative Works.   Alternatively, the knowledge gained from discussions between the parties on   product upgrading of any FT product is considered general know-how and can be   used by either
party.

             (e)          Amendment   of the Operating Agreement.    Rentech and HTIG agree that the Operating Agreement is hereby amended,   effective immediately prior to the Effective Date, to the extent necessary to   provide that the operating profit or loss, cash flow, and gain or loss from   the disposition of Company properties is specially allocated to them in   accordance with the allocations of ownership of Intellectual Property and   Derivative Works set forth in this Agreement.  The Members further agree that the Operating Agreement shall be   deemed amended immediately prior to the effective time to delete sections   4.1(c), 7.4, 9.4, 9.5 of the Operating Agreement. To the extent there is any   conflict between the terms of the FTS Contracts and this Agreement, the terms   of this Agreement shall prevail.

	
  
 
  	
  
 
  
	
  
 
  	
  
3.          Representations   and Warranties.  Each Party   represents, warrants and agrees that:

             (c)          EACH   PARTY ACKNOWLEDGES THAT IT HAS BEEN ADVISED BY ITS LEGAL COUNSEL AND IS   FAMILIAR WITH THE PROVISIONS OF CALIFORNIA CIVIL CODE SECTION 1542, WHICH   PROVIDES AS FOLLOWS:

             (e)          Each   Party further understands and agrees that the execution of this Agreement   shall not constitute or be construed as an admission of any liability   whatsoever on the part of any person or entity.
  
	
   
  	
  
 
  
	
  
 
  	
  
             (f)          Nothing   contained in the releases provided by this section of the Agreement shall be   deemed to release or discharge any Party’s obligations under this Agreement,   or under the Confidentiality Provisions.

             (c)          Amendments   in Writing.  Any amendment,   modification or waiver of any term or condition of this Agreement must be in   writing and signed by authorized representatives of all Parties.  No amendment, modification or waiver of   any term or condition of this Agreement shall be made orally or implied from   conduct or otherwise; and any such attempted amendment, modification or   waiver shall be null and void and of no force or effect.

comply as directed from such time forward.  All rights, remedies, undertakings,   obligations and agreements contained in this Agreement shall be cumulative   and not mutually exclusive.
