Between
Rentech, Inc.
and
Tom Samson

THIS AGREEMENT is made effective as of October 5, 2010 between Rentech, Inc. (the “Company”) and Tom Samson (“Executive”).

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. The Company shall employ Executive, and Executive hereby agrees to accept employment with the Company, upon the terms and conditions set forth in this Agreement, for the period beginning on October 5, 2010 (the “Commencement Date”) and ending as provided in Section 4 hereof (the “Employment Period”).

2. Position and Duties.

(a) During the Employment Period, Executive shall serve as Executive Vice President and Chief Development Officer of the Company. During the Employment Period, Executive shall render such administrative, financial and other executive and managerial services to the Company and its affiliates (the “Company Group”) as are consistent with Executive’s position and the by-laws of the Company and as the Chief Executive Officer (“CEO”) may from time to time reasonably direct. Executive shall also serve for no additional compensation or remuneration as an officer or director of such subsidiaries of the Company as may from time to time be designated by the CEO or the Board of Directors of the Company (the “Board”).

(b) During the Employment Period, Executive shall report to the CEO 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 Board and shall support and cooperate with the Company’s efforts to operate in conformity with the business and strategic plans approved by the Board. 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. Executive may serve as an officer or director of or otherwise participate in purely educational, welfare, social, religious and civic organizations so long as such activities do not interfere with Executive’s regular performance of duties and responsibilities hereunder in any material respect. 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, so long as such activities do not interfere with Executive’s regular performance of duties and responsibilities hereunder; provided, that Executive shall not have any ownership interest (of record or beneficial) in any firm, corporation, partnership, proprietorship or other business that competes directly with the Company’s Fischer-Tropsch business except for (x) an investment of not more than 1.0% of the outstanding securities of a company traded on a public securities exchange or (y) investments made through public mutual funds.

3. Compensation and Benefits.

(a) Base Salary. The Company shall pay Executive an annual salary (the “Base Salary”) at the rate of $340,000 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) Bonuses and Incentive Compensation.

(i) 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 50% 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 100% 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 or the Board’s Compensation Committee. The Company shall pay the Annual Bonus for each fiscal year 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 day of the third 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.

(ii) Equity Grant. The Company shall grant to Executive no later than December 31, 2010 (subject to Executive’s not having been terminated for Cause or resigned without Good Reason prior to such grant date) 350,000 restricted stock units (“Restricted Stock Units”). Each Restricted Stock Unit shall entitle Executive to receive one share of common stock of the Company (“Common Stock”) (or its equivalent, as determined in the sole discretion of the Board), within thirty (30) days after the applicable vesting date. Such Restricted Stock Units will vest over a three-year period such that one-third of the Restricted Stock Units will vest and be settled within 30 days on each of (i) the one-year anniversary of the Commencement Date, (ii) the two-year anniversary of the Commencement Date, and (iii) the three-year anniversary of the Commencement Date, in each case, subject to Executive’s continued employment with the Company through the applicable vesting date. Such Restricted Stock Units shall be referred to as the “Executive LTIP”. The terms and conditions of the Executive LTIP shall be governed by and subject to the award agreement to be entered into between Executive and the Company, substantially in the form of Exhibit A (the “LTIP Award Agreement”). Executive shall be eligible to be granted additional equity compensation in the future, at such time or times as the Board may determine; provided, however, that the ultimate decision to grant any such award(s) to Executive and the amount of any such award(s) to Executive (if granted) shall be determined by the Board in its sole discretion.

(iii) Commencement Payment. Within 30 days of the Commencement Date, the Company shall make a one-time payment to Executive of $25,000 (the “Commencement Payment”).

(c) Expenses. During the Employment Period, the Company shall, subject to Section 19 below, (i) reimburse 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 with respect to travel, entertainment and other business expenses for senior executives and (ii) pay to Executive a monthly automobile allowance of $1,000, provided that the first twelve months of Executive’s automobile allowance will be paid in a single lump sum payment of $12,000 with Executive’s first ordinary payroll check (the “Auto Allowance Prepayment”).

(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 of the Company as in effect from time to time, under the terms of such plans and to the same extent and under the same conditions such participation and coverages are provided generally to other senior executives of the Company;

(ii) coverage for services rendered to the Company, its subsidiaries and affiliates while Executive is a director or officer of the Company, or of any of its subsidiaries or affiliates, under director and officer liability insurance policy(ies) maintained by the Company from time to time; and

(iii) five weeks of vacation per year, provided, however, that Executive shall not at any time accrue vacation in excess of seven weeks’ total accrual, and Executive shall cease accruing vacation upon reaching such seven week accrual and shall not accrue any further vacation unless and until Executive’s vacation accrual is reduced below seven weeks.

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. The Employment Period shall end on the first anniversary of the Commencement Date; provided, however, that the Employment Period shall be automatically renewed for successive one-year terms thereafter on the terms and conditions of this Agreement in effect at the time of such renewal unless either party provides the other party with written notice that it has elected not to renew the Employment Period at least 90 days prior to the end of the initial Employment Period or any subsequent extension thereof. Notwithstanding the foregoing, (i) the Employment Period shall terminate immediately upon Executive’s resignation (with or without Good Reason, as defined herein), death or Disability (as defined herein) and (ii) the Employment Period may be terminated by the Company at any time prior to such date for Cause (as defined herein) or without Cause. Except as otherwise provided herein, any termination of the Employment Period by the Company shall be effective as specified in a written notice from the Company to Executive, but in no event more than 90 days from the date of such notice. The termination of the Employment Period shall not affect the respective rights and obligations of the parties which, pursuant to the terms of this Agreement, apply following the date of Executive’s termination of employment with the Company.

12. 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 Agreement, will be inoperative.

13. Complete Agreement. This Agreement and those documents expressly referred to herein (including without limitation the LTIP Award Agreement) embody the complete agreement and understanding among the parties and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way, including the employment agreement dated as of September 24, 2010.

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). The Company shall require any successor (whether direct or indirect, by purchase, merger, reorganization, consolidation, acquisition of property or stock, liquidation, or otherwise) to all or a majority of its assets, by agreement in form and substance satisfactory to Executive, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform this Agreement if no such succession had taken place. Executive may not assign his rights (except by will or the laws of descent and distribution or to a trust for the purpose of estate or tax planning for the benefit of Executive’s spouse and/or children) or delegate his duties or obligations hereunder. Except as provided by this Section 16, this Agreement is not assignable by any party and no payment to be made hereunder shall be subject to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or other charge.

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 (including, without limitation, the Company’s right to terminate 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 Commencement Date (“Section 409A”). Notwithstanding any provision of this Agreement to the contrary, in the event that following the Commencement 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 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 (i) preserve the intended tax treatment of the compensation and benefits payable hereunder, to preserve the economic benefits of such compensation and benefits, and/or to avoid less favorable accounting or tax consequences for the Company and/or (ii) to exempt the compensation and benefits payable hereunder from Section 409A or to comply with the requirements of Section 409A and thereby avoid the application of penalty taxes thereunder; provided, however, 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 5 above, shall be paid to Executive during the 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 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 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 6-month period, along with interest at the prime rate (as reported in the Wall Street Journal or such other source as the Company deems reliable) from the date such payments were otherwise due to the date of payment. 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.

(c) Reimbursements. To the extent that any reimbursements, including without limitation any reimbursements pursuant to Section 3(c) above or Section 23 below, are determined to constitute taxable compensation to Executive, then such reimbursements shall be paid to Executive promptly following proper substantiation in accordance with applicable Company policy, but in no event after December 31st of the year following the year in which the expense was incurred (and such reimbursements shall be contingent upon Executive’s timely submission of proper substantiation). The amount of any such expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year and Executive’s right to reimbursement of any such expenses shall not be subject to liquidation or exchange for any other benefit.

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.

22. Arbitration. Any dispute or controversy arising under or in connection with this Agreement or otherwise in connection with the Executive’s employment by the Company that cannot be mutually resolved by the parties to this Agreement and their respective advisors and representatives shall be settled exclusively by arbitration in Los Angeles, California in accordance with the rules of the American Arbitration Association before one arbitrator of exemplary qualifications and stature, who is a retired California Superior Court Judge, 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 two individuals cannot agree on the selection of the arbitrator, who 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, at his or her election, award attorneys’ fees to the prevailing party, if permitted by applicable law.

23. Moving Expenses. The Company agrees that in connection with the commencement of Executive’s employment hereunder it will reimburse Executive for the following costs of relocating to the Los Angeles area:

(a) The reasonable, documented, out-of-pocket costs of up to two house hunting trips for the Executive and his spouse, up to a maximum cost of $3,000 per trip;

(b) Moving expenses including: (i) the reasonable, documented, out-of-pocket costs to transport the Executive’s household goods from Atlanta, Georgia to the Los Angeles, California area, up to a maximum cost of $20,000 (ii) transportation (one-way ground and coach air travel, consistent with the Company’s reimbursement policies) for Executive’s immediate family from Atlanta to Los Angeles; and (iii) up to two weeks of reasonable, documented, out-of-pocket costs of temporary living support for Executive’s immediate family when they move from Atlanta to Los Angeles, up to a maximum cost of $5,000;

(c) The reasonable, documented, out-of-pocket costs of temporary living support for up to nine (9) months while the Executive’s household is closing in Atlanta and the Executive is working in Los Angeles, consistent with the Company’s Transient Employee Per Diem Policy, it being understood that this Section 23(c) shall terminate upon the occurrence of the Permanent Housing Date;

(d) A miscellaneous relocation expense allowance to cover other reasonable documented out of pocket expenses incurred as part of the Executive’s relocation (and incurred no later than thirty (30) days after such relocation), up to $40,000 (the “Allowance”); and

(e) Commencing with the date of the closing of the Executive’s home purchase or, in the alternative, the date he first occupies non-transitional rental housing, in either case, in the Los Angeles, California area (such date, the “Permanent Housing Date”), a housing allowance (the “Housing Allowance”) of (i) $60,000 per year for the period of one year after the Permanent Housing Date, (ii) 40,000 per year for the period of the second year after the Permanent Housing Date and (iii) $20,000 per year for the third year after the Permanent Housing Date, such allowance to be paid on a periodic basis at the same time, and in addition to the Base Salary and payable so long as the Employment Period has not been terminated; provided, however, that in the event of Executive’s termination of employment with the Company (1) by the Company without Cause, (2) by reason of the Company electing not to offer to renew the Agreement on terms and conditions substantially similar to those contained herein, if, 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, or (3) by Executive for Good Reason, the Housing Allowance shall (subject to any limitations as to timing imposed by Section 19 hereof) continue to be paid in accordance with this Section 23(e) until the first to occur of (w) one year from the date of such termination, (x) the third anniversary of the Permanent Housing Date, (y) the date that Executive accepts substitute employment or (z) the date such home is sold or, if leased, the lease obligation is terminated; provided, further, however, that from and after the termination of employment Executive shall use his reasonable efforts in good faith to satisfy either clause (y) or (z) so as to mitigate the Company’s obligations under this Section 23(e).

(f) During the period commencing on the Permanent Housing Date, should Executive and his family move into Executive’s new home in the Los Angeles area prior to selling his home in Atlanta, the Company will reimburse Executive for up to $3,000 per month of reasonable, documented, out-of-pocket duplicate housing expenses (the “Duplicate Housing Allowance”) for up to a maximum of six months, contingent upon Executive providing documentation of making mortgage or lease payments on both homes during this period. The Duplicate Housing Allowance shall be paid on a periodic basis at the same time, and in addition to the Base Salary and payable so long as the Employment Period has not been terminated; provided, however, that in the event of Executive’s termination of employment with the Company (1) by the Company without Cause, (2) by reason of the Company electing not to offer to renew the Agreement on terms and conditions substantially similar to those contained herein, if, 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, or (3) by Executive for Good Reason, the Duplicate Housing Allowance shall (subject to any limitations as to timing imposed by Section 19 hereof) continue to be paid in accordance with this Section 23(f) until the first to occur of (x) the six month anniversary of the Permanent Housing Date, (y) the date that Executive accepts substitute employment or (z) the date Executive ceases making mortgage or lease payments on either of his homes; provided, further, however, that from and after the termination of employment Executive shall use his reasonable efforts in good faith to satisfy either clause (y) or (z) so as to mitigate the Company’s obligations under this Section 23(f).

24. 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 Group 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 the Employment Period); provided, however, that any such request by the Company shall not be unduly burdensome or 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 24, 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 reasonable documentation. In the event that the obligations under this Section 24 require more than 20 hours of the Executive’s time after the termination of the Employment Period, the Company shall thereafter also pay to Executive compensation at an hourly rate equal to the result of (a) the Base Salary applicable on the date of the termination of Executive’s employment, divided by (b) 1,750.

7. Tax Withholding.

The Committee may, in its sole discretion and in satisfaction of the foregoing requirement, allow the Executive to elect to have the Company withhold shares of Stock otherwise issuable under this Agreement (or allow the return of shares of Stock) having a Fair Market Value equal to the sums required to be withheld, provided, that the number of shares of Stock which may be so withheld with respect to a taxable event arising in connection with the RSUs shall be limited to the number of shares which have a Fair Market Value on the date of withholding equal to the aggregate amount of such liabilities based on the minimum statutory withholding rates for federal, state and local income tax and payroll tax purposes that are applicable to such supplemental taxable income.

Neither the Executive nor any person claiming under or through the Executive will have any of the rights or privileges of a stockholder of the Company in respect of any shares of Stock deliverable hereunder unless and until certificates representing such shares of Stock will have been issued, recorded on the records of the Company or its transfer agents or registrars, and delivered to the Executive or any person claiming under or through the Executive.

9. Non-Transferability. The rights and privileges conferred hereby shall not be transferred, assigned, pledged or hypothecated by the Executive in any way in favor of any party other than the Company or a Subsidiary (whether by operation of law or otherwise) other than to a trust for the purpose of estate or tax planning for the benefit of Executive’s spouse and/or children, and shall not be subjected to any lien, obligation or liability of the Executive to any party other than the Company or a Subsidiary, other than by the laws of descent and distribution. Upon any attempt by the Executive to transfer, assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale by the Executive under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby shall immediately become null and void. Notwithstanding the foregoing, the Company may assign any of its rights under this Agreement to single or multiple assignees, in which case any such assignee shall perform this Agreement in the same manner and to the same extent that the Company would be required to perform this Agreement if no such assignment had taken place, and this Agreement shall inure to the benefit of the successors and assigns of the Company.

10. Distribution of Stock. Notwithstanding anything herein to the contrary, the Company shall not be required to issue or deliver any certificates evidencing shares of Stock pursuant to this Agreement unless and until the Committee has determined, with advice of counsel, that the issuance and delivery of such certificates is in compliance with all applicable laws, regulations of governmental authorities and, if applicable, the requirements of any exchange on which the shares of Stock are listed or traded. All Stock certificates delivered pursuant to this Agreement shall be subject to any stop-transfer orders and other restrictions as the Committee deems necessary or advisable to comply with federal, state, or foreign jurisdiction, securities or other laws, rules and regulations and the rules of any national securities exchange or automated quotation system on which the Stock is listed, quoted, or traded. The Committee may place legends on any Stock certificate to reference restrictions applicable to the Stock. In addition to the terms and conditions provided herein, the Committee may require that the Executive make such reasonable covenants, agreements, and representations as the Committee, in its discretion, deems advisable in order to comply with any such laws, regulations, or requirements. The Committee shall have the right to require the Executive to comply with any timing or other restrictions with respect to the settlement of any RSUs, including a window-period limitation, as may be imposed in the discretion of the Committee. Notwithstanding any other provision of this Agreement, unless otherwise determined by the Committee or required by any applicable law, rule or regulation, the Company shall not deliver to the Executive any certificates evidencing shares of Stock issued upon settlement of any RSUs under this Agreement and instead such shares of Stock shall be recorded in the books of the Company (or, as applicable, its transfer agent or stock plan administrator).

11. Adjustments in Capitalization.

a. In the event of any stock dividend, stock split, combination or exchange of shares, merger, consolidation, spin-off, recapitalization or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other change affecting the shares of Stock or the share price of the Stock, the Committee shall make proportionate adjustments to any or all of the following in order to reflect such change: (a) the aggregate number and kind of shares that may be issued under this Agreement; and (b) the terms and conditions of the RSUs. Any adjustment affecting an Award intended as Qualified Performance-Based Compensation shall be made consistent with the requirements of Section 162(m) of the Code.

b. In the event of any transaction or event described in Section 11(a) above or any unusual or nonrecurring transactions or events affecting the Company, any affiliate of the Company, or the financial statements of the Company or any affiliate, or of changes in applicable laws, regulations or accounting principles, the Committee, in its sole discretion and on such terms and conditions as it deems appropriate, either by the terms of this Agreement or by action taken prior to the occurrence of such transaction or event and either automatically or upon the Executive’s request, is hereby authorized to take any one or more of the following actions whenever the Committee determines that such action is appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under this Agreement, to facilitate such transactions or events or to give effect to such changes in laws, regulations or principles:

i.

To provide for either (A) termination of this Agreement in exchange for an amount of cash, if any, equal to the amount that would have been attained upon the vesting and payment of RSUs under this Agreement as of the date of such termination (and, for the avoidance of doubt, if, as of the date of the occurrence of the transaction or event described in this Section 11(b), the Committee determines in good faith that no amount would have been attained upon the realization of the Executive’s rights, then the RSUs may be terminated by the Company without payment), or (B) the replacement of such RSUs with other rights or property selected by the Committee in its sole discretion;

ii.

To provide that the RSUs be (A) assumed by a successor or survivor corporation, or a parent or subsidiary thereof, or (B) substituted for by a similar award covering the stock of a successor or survivor corporation, or a parent or subsidiary thereof, in either case, with appropriate adjustments as to the number and kind of shares and prices;

iii.

To make adjustments in the number and type of shares of Stock (or other securities or property) subject to the RSUs and/or in the terms and conditions of the RSUs;

iv.

To provide that RSUs subject to this Agreement shall be payable or fully vested with respect to all shares covered thereby, notwithstanding anything to the contrary in this Agreement; and

v.

To provide that the RSUs cannot vest or become payable after such event.

12. Authority. The Committee or the Board, as applicable, shall have the power to interpret this Agreement and to adopt and interpret such rules for its administration, interpretation and application as are consistent with the terms hereof (including, but not limited to, the determination of whether or not any RSUs have vested and become payable). All actions taken and all interpretations and determinations made by the Committee or the Board in good faith will be final and binding upon the Executive, the Company and any and all other interested persons. No member of the Committee or the Board will be personally liable for any action, determination or interpretation made in good faith with respect to this Agreement and, to the greatest extent allowable pursuant to applicable law, each member of the Committee and the Board shall be fully indemnified and held harmless by the Company from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by such member in connection with such administration of this Agreement.

13. No Effect on Service Relationship. Nothing in this Agreement shall confer upon the Executive any right to serve or continue to serve as an employee, consultant or director of the Company or its affiliates.

14. Severablility. In the event that any provision in this Agreement is held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of this Agreement, which shall remain in full force and effect.

15. Tax Consultation. The Executive understands that he may suffer adverse tax consequences in connection with the RSUs granted pursuant to this Agreement. The Executive represents that the Executive has consulted with any tax consultants that he deems advisable in connection with the RSUs and that the Executive is not relying on the Company for tax advice.

16. Amendment. Subject to Section 12 above and Section 18 below, this Agreement may only be amended, modified or terminated by a writing executed by the Executive and by a duly authorized representative of the Company.

17. Relationship to other Benefits. Neither the RSUs nor payment in respect thereof shall be taken into account in determining any benefits pursuant to any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary.

18. Code Section 409A.

a. General. To the extent that the Committee determines that any RSUs may not be exempt from or compliant with Code Section 409A, the Committee may amend this Agreement in a manner intended to comply with the requirements of Code Section 409A or an exemption therefrom (including amendments with retroactive effect), or take any other actions as it deems necessary or appropriate to (i) exempt the RSUs from Code Section 409A and/or preserve the intended tax treatment of the benefits provided with respect to the RSUs, or (ii) comply with the requirements of Code Section 409A. To the extent applicable, this Agreement shall be interpreted in accordance with the provisions of Code Section 409A. Notwithstanding anything herein to the contrary, the Executive expressly agrees and acknowledges that in the event that any taxes are imposed under Code Section 409A in respect of any compensation or benefits payable to the Executive, then (A) the payment of such taxes shall be solely the Executive’s responsibility, (B) neither the Company nor any of its past or present directors, officers, employees or agents shall have any liability for any such taxes and (C) the Executive shall indemnify and hold harmless, to the greatest extent permitted under law, each of the foregoing from and against any claims or liabilities that may arise in respect of any such taxes.

b. Potential Six-Month Delay. Notwithstanding anything to the contrary in this Agreement, no shares of Stock (or other amounts) shall be paid to the Executive during the 6-month period following the Executive’s “separation from service” (within the meaning of Section 409A(a)(2)(A)(i) of the Code, and Treasury Regulation Section 1.409A-1(h)) (“Separation from Service”) to the extent that the Company determines that the Executive is a “specified employee” (within the meaning of Code Section 409A) at the time of such Separation from Service and that paying such amounts at the time or times indicated in this Agreement would be a prohibited distribution under Code Section 409A(a)(2)(b)(i). 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 6-month period (or such earlier date upon which such amount can be paid under Code Section 409A without being subject to such additional taxes), the Company shall pay to the Executive in a lump-sum all shares of Stock that would have otherwise been payable to the Executive during such 6-month period under this Agreement.

19. Governing Law. The laws of the State of California shall govern the interpretation, validity, administration, enforcement and performance of the terms of this Agreement regardless of the law that might be applied under principles of conflicts of laws.

20. Captions. Captions provided herein are for convenience only and are not to serve as a basis for interpretation or construction of this Agreement.

21. Fractional Shares. No fractional shares of Stock shall be issued under this Agreement and the Committee shall determine, in its discretion, whether cash shall be given in lieu of fractional shares or whether such fractional shares shall be eliminated by rounding up or down as appropriate.

22. Section 16 Limitations. Notwithstanding any other provision of this Agreement, if the Executive is subject to Section 16 of the Exchange Act, then this Agreement shall be subject to any additional limitations set forth in any applicable exemptive rule under Section 16 of the Exchange Act (including any amendment to Rule 16b-3 under the Exchange Act) that are requirements for the application of such exemptive rule. To the extent permitted by applicable law, this Agreement shall be deemed amended to the extent necessary to conform to such applicable exemptive rule.

FORM OF RELEASE

This General Release of all Claims (this “Agreement”) is entered into by Tom Samson (“Executive”) and Rentech, Inc. (the “Company”), effective as of [______].

In further consideration of the promises and mutual obligations set forth in the Employment Agreement between Executive and the Company, dated _____, 2010 (the “Employment Agreement”), Executive and the Company agree as follows:

1. Return of Property. All Company files, access keys, desk keys, ID badges, computers, electronic devices, telephones and credit cards, and such other property of the Company as the Company may reasonably request, in Executive’s possession must be returned no later than the date of Executive’s termination from the Company.

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; the California Fair Employment and Housing Act, as amended, Cal. Lab. Code § 12940 et seq.; the California Equal Pay Law, as amended, Cal. Lab. Code §§ 1197.5(a),1199.5; the Moore-Brown-Roberti Family Rights Act of 1991, as amended, Cal. Gov’t Code §§12945.2, 19702.3; California Labor Code §§ 1101, 1102, 69 Ops. Cal. Atty. Gen. 80 (1986); California Labor Code §§ 1102.5(a), (b); the California WARN Act, Cal. Lab. Code § 1400 et seq.; the California False Claims Act, Cal. Gov’t Code § 12650 et seq.; the California Corporate Criminal Liability Act, Cal. Penal Code § 387; and the California Labor Code, 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 the termination of such relationship 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 the Employment Agreement 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 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 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”) or the California Department of Fair Employment and Housing (“DFEH”) 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.

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-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 or the DFEH 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.

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 California regardless of the law that might be applied under principles of conflicts of laws.

8. Arbitration. Any dispute or controversy arising under or in connection with this Agreement or otherwise in connection with Executive’s employment by the Company that cannot be mutually resolved by the parties to this Agreement and their respective advisors and representatives shall be settled exclusively by arbitration in Los Angeles, California in accordance with the rules of the American Arbitration Association before one arbitrator of exemplary qualifications and stature, who shall be a retired California Superior Court Judge and 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 two individuals cannot agree on the selection of the arbitrator, who 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, at his or her election, award attorneys’ fees to the prevailing party, if permitted by applicable law.

9. Notices. All notices or communications hereunder shall be in writing, addressed as follows:
