Ladies and Gentlemen:

Reference is hereby made to the Credit Agreement, dated as of January 29, 2010 (as amended, amended and restated, supplemented or otherwise modified from time to time, the “Credit Agreement”), among Rentech Energy Midwest Corporation (the “Borrower”), Rentech, Inc. (“Holdings”), the banks, financial institutions and other entities party to the Credit Agreement as lenders (the “Lenders”), Credit Suisse AG, Cayman Islands Branch, as administrative agent (in such capacity, the “Administrative Agent”) and as collateral agent (in such capacity, the “Collateral Agent”). Unless otherwise defined herein, terms defined in the Credit Agreement and used herein shall have the meanings given to them in the Credit Agreement.

Each Lender (each, an “Incremental Lender”) party to this Second Incremental Loan Assumption Agreement (including Annex I hereto, this “Second Incremental Loan Assumption Agreement”) hereby severally agrees to provide the Incremental Loan Commitment set forth opposite its name on Annex I hereto (for each such Incremental Lender, its “Incremental Loan Commitment”). Each Incremental Loan Commitment provided pursuant to this Second Incremental Loan Assumption Agreement shall be subject to the terms and conditions set forth in the Credit Agreement, including Section 2.21 thereof.

This Second Incremental Loan Assumption Agreement constitutes the Borrower’s written request to the Administrative Agent for Incremental Loan Commitments pursuant to Section 2.21(a) of the Credit Agreement (the “Incremental Loan Commitment Request”) and, in connection therewith, the Borrower hereby notifies the Administrative Agent that: (i) the amount of the Incremental Loan Commitments being requested is $52,000,000, (ii) the date on which such Incremental Loan Commitments are requested to be effective is November 26, 2010, and (iii) such Incremental Loan Commitments are commitments to make Other Loans.

Each Incremental Lender acknowledges and agrees that the Incremental Loan Commitments provided pursuant to this Second Incremental Loan Assumption Agreement, in the aggregate amount set forth on Annex I hereto, shall constitute Commitments under the Credit Agreement for Other Loans increasing the amount of the Commitments in effect immediately prior to the effectiveness of this Second Incremental Loan Assumption Agreement.

Each of the parties to this Second Incremental Loan Assumption Agreement hereby agrees to the terms and conditions set forth in the second preceding paragraph and on Annex I hereto in respect of each Incremental Loan Commitment and the Other Loans provided pursuant to this Second Incremental Loan Assumption Agreement.

Each Incremental Lender party to this Second Incremental Loan Assumption Agreement (i) confirms that it has received a copy of the Credit Agreement and the other Loan Documents, together with copies of the financial statements referred to therein and such other documents and information as it has deemed appropriate to make its own credit analysis and decision to enter into this Second Incremental Loan Assumption Agreement and to become an Incremental Lender under the Credit Agreement, (ii) agrees that it will, independently and without reliance upon the Administrative Agent, the Collateral Agent, any Lender or any other Person and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under the Credit Agreement and the other Loan Documents, (iii) appoints and authorizes each of the Administrative Agent and the Collateral Agent to take such action as agent on its behalf and to exercise such powers under the Credit Agreement and the other Loan Documents as are delegated to the Administrative Agent and the Collateral Agent, as the case may be, by the terms thereof, together with such powers as are reasonably incidental thereto, (iv) agrees that it will perform, in accordance with their terms, all of the obligations which by the terms of the Credit Agreement are required to be performed by it as a Lender, and (v) in the case of each Incremental Lender (if any) that is a Foreign Lender, attaches the documentation required under Section 2.15(e) of the Credit Agreement.

This Second Incremental Loan Assumption Agreement, and the Incremental Loan Commitments provided hereunder, shall become effective on the date (the “Incremental Loan Closing Date”) upon which all of the conditions set forth in Section 3 of Annex I hereto are satisfied. Upon the Incremental Loan Closing Date, each Incremental Lender party hereto shall automatically become a Lender pursuant to the Credit Agreement and, except as otherwise expressly provided in Section 2 of Annex I hereto, shall have the rights and obligations of a Lender thereunder and under the other Loan Documents. The Administrative Agent shall promptly notify each Lender of the occurrence of the Incremental Loan Closing Date.

The Borrower hereby acknowledges and agrees that (i) it shall be liable for all Obligations with respect to the Incremental Loan Commitments provided pursuant to this Second Incremental Loan Assumption Agreement, including any Other Loans made pursuant to the Incremental Loan Commitments and (ii) all such Obligations shall be secured by the Collateral under, and be entitled to the benefits of, the Security Documents.

Each Guarantor hereby acknowledges and agrees that (i) its consent to this Second Incremental Loan Assumption Agreement is not required, but each Guarantor nevertheless hereby agrees and consents to this Second Incremental Loan Assumption Agreement and to the documents and agreements referred to herein, (ii) notwithstanding the effectiveness of this Second Incremental Loan Assumption Agreement, such Guarantor’s Guarantee shall remain in full force and effect without modification thereto, (iii) nothing herein shall in any way limit any of the terms or provisions of any Guarantor’s Guarantee or any other Loan Document executed by any Guarantor (as the same may be amended, amended and restated,

supplemented or otherwise modified from time to time), all of which are hereby ratified, confirmed and affirmed in all respects, (iv) all Obligations with respect to the Incremental Loan Commitments provided pursuant to this Second Incremental Loan Assumption Agreement and any Other Loans made pursuant to the Incremental Loan Commitments shall be (x) fully guaranteed pursuant to the Guarantee and Collateral Agreement in accordance with the terms and provisions thereof and (y) secured by the Collateral under, and be entitled to the benefits of, the Security Documents, (v) no other agreement, instrument, consent or document shall be required to give effect to this paragraph, and (vi) the Borrower, Holdings, the Agents and any Lender may from time to time enter into any further amendments, modifications, terminations and/or waivers of any provisions of the Loan Documents without notice to or consent from any Guarantor (other than, to the extent expressly required under Section 9.08 of the Credit Agreement, Holdings) and without affecting the validity or enforceability of any Guarantor’s Guarantee or Collateral or giving rise to any reduction, limitation, impairment, discharge or termination of any Guarantor’s Guarantee or Collateral.

This Second Incremental Loan Assumption Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Second Incremental Loan Assumption Agreement by telecopier or other electronic transmission shall be effective as delivery of a manually executed counterpart of this Second Incremental Loan Assumption Agreement.

After the execution and delivery to the Administrative Agent of a fully executed copy of this Second Incremental Loan Assumption Agreement by the parties hereto, this Second Incremental Loan Assumption Agreement may be changed, modified or varied only by written instrument in accordance with the requirements for the modification of any Loan Document pursuant to Section 9.08(b) of the Credit Agreement.

THIS SECOND INCREMENTAL LOAN ASSUMPTION AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAW OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES THAT WOULD REQUIRE THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

Neither the Borrower nor Holdings shall assign or delegate any of their respective rights or obligations under this Second Incremental Loan Assumption Agreement without the prior written consent of each of the other parties hereto (and any attempted assignment or delegation without such consent shall be null and void). This Second Incremental Loan Assumption Agreement is intended to be solely for the benefit of the parties hereto, and is not intended to confer any benefits upon, or create any rights in favor of, any Person other than the parties hereto.

The Borrower may accept this Second Incremental Loan Assumption Agreement by executing and delivering and returning a copy of this Second Incremental Loan Assumption Agreement to the Administrative Agent before 8:00 p.m. (New York City time) on November 24, 2010.
