Section 16(a) Beneficial Ownership Reporting
Compliance

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires Rentechs
executive officers and directors, and persons who own more than ten percent of a registered class of Rentechs equity securities (collectively, Insiders), to file initial reports of ownership and reports of changes in ownership with
the Securities and Exchange Commission (the SEC). Insiders are required by SEC regulations to furnish Rentech with copies of all Section 16(a) forms they file. To Rentechs knowledge, based solely on its review of the copies of
such reports furnished to Rentech or written representations from certain Insiders that they were not required to file a Form 5 to report previously unreported ownership or changes in ownership, we believe that, during our fiscal year ended
September 30, 2011, the Insiders complied with all such filing requirements except for a Form 4 filed one day late reporting the vesting of restricted stock units and performance units on April 1, 2011.

ITEM 11.EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Executive Summary

This Compensation Discussion and Analysis provides an overview and analysis of the executive compensation program for our
named executive officers identified below, or our NEOs. Our executive compensation program is designed to align executive pay with individual performance on both short and long-term bases; to link executive pay to specific, measurable
financial, technological and development achievements intended to create value for shareholders; and to utilize compensation as a tool to attract and retain the high-caliber executives that are critical to our long-term success.

The following table sets forth the key elements of our NEOs compensation, along with the primary objectives
associated with each element of compensation.

|Base salary                                    |  | To recognize performance of job responsibilities, provide stable income and attract and retain experienced individuals with superior talent.

|Retirement savings (401(k) plan)               |  | To provide an opportunity for tax-efficient savings and matching contributions by us.

To serve the foregoing objectives, our overall compensation program is generally designed
to be flexible rather than purely formulaic. In alignment with the objectives set forth above, the Compensation Committee of the Board of Directors of Rentech and the full Board of Directors, including during executive sessions without our
management team present, have generally determined the overall compensation of our NEOs and its allocation among the elements described above, relying on the analyses and advice provided by Rentechs compensation consultant as well as input
from our management team.

This discussion is intended to be read in conjunction with the executive
compensation tables and related disclosures that follow this Compensation Discussion and Analysis.

Compensation Program Objectives

The following discussion and analysis describes our compensation objectives and policies as applied
to D. Hunt Ramsbottom, our Chief Executive Officer, Dan J. Cohrs, our Chief Financial Officer, Tom Samson, our Executive Vice President and Chief Development Officer, Harold A. Wright, our Senior Vice President and Chief Technology Officer, Colin M.
Morris, our Senior Vice President, General Counsel and Secretary and Douglas M. Miller, our former Executive Vice President  Project Development, who served as our NEOs during fiscal year 2011. At the end of fiscal year 2011, Mr. Miller
no longer served as an executive officer of our Company and Mr. Samson will depart our Company effective February 3, 2012 to pursue other opportunities.

To succeed in achieving our key operational goals, we need to recruit and retain a highly talented and seasoned team of
executive, technical, sales, marketing, operations, financial and other business professionals. As such, our compensation packages are designed to incentivize the achievement of these goals, and to recruit, reward and retain our employees, including
our NEOs.

We have focused on building an experienced management team that is capable of managing the
Companys day-to-day operations during a period of growth while working to achieve our long-term operational goals. We believe it is important both to retain our key executives, including our NEOs, and to recruit the additional talent we need
to expand the Company. Accordingly, our policy is to hire executives who are not only highly qualified for their positions at our current size, but who also have the skills we believe are necessary to perform their roles at the same high standard if
we are successful in our commercial development, and our Company achieves significantly greater size and complexity.

Each of the key elements of our executive compensation program is discussed in more detail below under Core Components of Executive Compensation.

Compensation Consultant

During fiscal years 2010 and 2011, our Compensation Committee engaged Radford, an Aon Hewitt Company, as an independent
compensation consultant to assist in the continuing analysis of the executive compensation program for certain of our officers, including our NEOs. Services provided by Radford during fiscal year 2011 with respect to our NEOs included:



| |  | Analyzing and verifying our peer group companies and applicable benchmarks;
| | - | ---------------------------------------------------------------------------



| |  | Providing compensation survey data and assisting our Compensation Committee with the interpretation of this data; and
| | - | ---------------------------------------------------------------------------------------------------------------------



| |  | Advising on the reasonableness and effectiveness of our compensation components, levels and programs for our directors and officers, including our
NEOs.
| | - | --------------------------------------------------------------------------------------------------------------------------------------------------------

Our current peer group was established in 2010 based on discussions among the members
of our Compensation Committee, certain of our executive officers and Radford. The peer group consists of alternative energy companies and certain technology companies with a related focus, in each case, with (i) annual revenues ranging from $50
million to $550 million, (ii) market values ranging from $80 million to $750 million, (iii) revenues ranging from $50 million to $550 million (with a median of $316 million), and (iv) similar employee numbers. Following are the
companies that comprise our current peer group:

##### Table of Contents

In mid-2011, our Compensation Committee reviewed data points as a benchmark
for various elements of executive compensation, including base salaries, target incentive as a percentage of salary, total cash compensation, long-term incentives and total direct compensation, based on information gathered from the public filings
of our peer companies set forth above. Our Compensation Committee also reviewed aggregated published survey data from Radfords 2011 Global Technology Survey (using a data set comprised of public high-tech companies with revenue between $50
million and $500 million) in order to validate its benchmarks.

Our Compensation Committee determined that the
compensation of our NEOs in totality, and with respect to individual components of compensation, was generally above the market median at that time (with the exception of Mr. Ramsbottoms base salary, which was slightly below the median),
yet within reasonable market practices and in line with our compensation philosophy and strategy. Specifically, our base salaries and target total cash compensation were on average higher than the median of the market data. A comparison of our
long-term incentives and total direct compensation (comprised of base salary, annual cash incentives and equity incentives) also revealed levels above the median of the market data for our NEOs. Based on this analysis, we concluded that the level of
our total compensation was well positioned to attract and retain the type of management team that we believe is necessary to successfully implement our commercialization strategy. We believe that these levels and types of compensation are also
consistent with our compensation philosophy and foster our compensation objectives.

Based on Radfords
2011 evaluation of our compensation, we believe that the total compensation package provided for fiscal year 2011 continued to pay our executives at median levels of the market for average performance, with compensation that would approximate the
75th percentile of the market for exceptional performance.

Radford serves at the discretion of Rentechs
Compensation Committee and may be terminated by that committee. Radfords total fee for services provided to our Compensation Committee for fiscal year 2011 was approximately $60,000.

Core Components of Executive Compensation

Through
our Compensation Committee, we design the principal components of our executive compensation program to fulfil one or more of the principles and objectives described above. Compensation of our NEOs consists of the following elements:



| |  |  | Cash compensation comprised of base salary and annual cash incentive compensation;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | Equity incentive compensation;
| | - |  | ------------------------------



| |  |  | Certain severance and change in control benefits;
| | - |  | -------------------------------------------------



| |  |  | Health and welfare benefits and certain limited perquisites and other personal benefits; and
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | Retirement savings (401(k)) plan.
| | - |  | ---------------------------------

We view each component of our executive compensation program as related but distinct, and we have historically reassessed the total compensation of our NEOs periodically to ensure that overall
compensation objectives are met. In addition, in determining the appropriate level for each compensation component, we have considered, but not exclusively relied on, our understanding of the competitive market based on the collective experience of
members of our Compensation Committee (and our Chief Executive Officer with regard to the other NEOs), our recruiting and retention goals, our view of internal equity and consistency, the length of service of our executives, our overall financial
and operational performance and other relevant considerations.

We have not adopted any formal or informal
policies or guidelines for allocating compensation between currently-paid and long-term compensation, between cash and non-cash compensation, or among different forms of non-cash compensation. Generally, we provide a competitive, but balanced, total
compensation package that provides the stability of a competitive, stable income while affording our executives the opportunity to be appropriately rewarded through cash and equity incentives if we attain our goals and perform well over time.

Each of the primary elements of our executive compensation program is discussed in more detail below. While
we have identified particular compensation objectives that each element of executive compensation serves, our compensation programs are intended to be flexible and complementary and to collectively serve all of the executive compensation objectives
described above. Accordingly, whether or not specifically mentioned below, we believe that, as a part of our overall executive compensation policy, each individual element, to a greater or lesser extent, serves each of our compensation objectives.

Cash Compensation

We provide our NEOs with cash compensation in the form of base salaries and annual cash incentive awards. Our cash
compensation is structured to provide a market-level base salary for our NEOs while creating an opportunity to exceed market levels for total cash compensation if short- and long-term performance exceeds expectations. We believe that this mix
appropriately combines the stability of non-variable compensation (in the form of base salary) with variable performance awards (in the form of annual cash incentives) that reward the performance of the Company and individual contributions to the
success of the business.

Base Salary

Base salaries for our NEOs were initially set in arms-length negotiations during the hiring processes for these
executives. These base salaries have historically been reviewed annually by our Compensation Committee (with input from our Chief Executive Officer with respect to the other NEOs) and were again reviewed at the end of 2010 for purposes of
determining 2011 salaries. Our NEOs are not entitled to any formulaic base salary increases.

Effective
January 2011, Mr. Ramsbottoms base salary increased by approximately 5% to $440,000 in recognition of his leadership of Rentech and to more closely align his salary to the median salary in our peer group. Mr. Cohrs base salary
also increased in January 2011 by approximately 4% to $377,500, effective as of January 2011, in recognition of his effective capital raising efforts on behalf of Rentech and his continued leadership as our Chief Financial Officer. Mr. Samson
was hired in fiscal year 2011 and neither his nor Mr. Millers salary changed in fiscal year 2011. Mr. Wrights salary was increased 3% to $278,000, effective January 2011, in recognition of the continuing improvements to
the Companys technologies. Mr. Morris salary was increased 5% to $248,300, effective January 2011, in recognition of his performance and to bring his base salary closer to the median of the Companys peer group.

The base salaries for our NEOs, both prior to and following their salary increases are set forth in the
following table:

In connection with the closing of the initial public offering (the IPO) of
Rentech Nitrogen Partners, L.P. (RNP), effective November 7, 2011, we increased the base salaries of Messrs. Ramsbottom, Cohrs and Morris by an additional 10% to compensate these executives for their expanded responsibilities,
duties and exposure to potential liabilities as senior officers of two publicly traded companies. These IPO-related base salary increases, which are not reflected in the table above (as they occurred after the end of our 2011 fiscal year), are
additional to any annual increases that our Compensation Committee may make to the base salaries of these individuals in connection with annual salary reviews during our fiscal year 2012.

Annual Incentive Compensation

We maintain an annual incentive program to reward executive officers, including our NEOs, based on our financial and
operational performance, achievement of specific milestones related to technology, financing and project development work associated with our business, operation and expansion of our nitrogen fertilizer business, and the individual NEOs
relative contribution to that performance during the year (referred to below as the our annual incentive program). We recognize that successful completion of short-term objectives is critical in achieving our planned level of growth and attaining
our long-term business objectives. Accordingly, our annual incentive program is designed to reward executives for successfully taking the immediate steps necessary to implement our long-term business strategy.

##### Table of Contents

Annual Incentive Program.During 2011, each of our NEOs was eligible
to receive an incentive payment pursuant to our annual incentive program, under which cash incentives are determined and paid by reference to (i) the achievement of certain pre-established financial and other performance criteria, and
(ii) target bonus amounts (as set forth in the NEOs respective employment agreements). In the beginning of each fiscal year (including 2011), our CEO and other senior officers develop a series of broad objectives, which are then reviewed
and revised by our Compensation Committee and Board of Directors. Following that review, our Board of Directors sets the performance goals for the year, but retains discretion based on input from the Compensation Committee (and our Chief Executive
Officer with respect to the other NEOs who participate in the annual incentive program) to increase or decrease annual incentive awards to levels as high as 200% of the NEOs target bonus and as low as zero, in each case, based on performance
during the relevant period.

For fiscal year 2011, the annual incentive awards are targeted (i) for
Messrs. Ramsbottom and Cohrs at 100% and 60% of their respective base salaries and (ii) for Messrs. Samson, Wright and Morris at 50% of their respective base salaries, in each case, in accordance with their respective employment agreements.
Payment of annual incentive awards to our NEOs is based on the achievement of specific financial targets, as well as certain technology, financial and development milestones relating to the development of our alternative energy business, the
performance of RNP and the performance of the individual executive.

Performance Goals Applicable to Our
NEOs

The performance goals applicable to our NEOs for fiscal year 2011 are set forth below, along with
determinations as to the attainment of these goals (parentheticals following the description of each goal provide guidelines indicating the approximate weight given to the attainment of each goal by our Compensation Committee).



| | 1. | Goal: A continued strong safety record at Rentechs and RNPs facilities, with an OSHA recordable rate at or below 4.0 (failure to
attain this goal would reduce the final bonus pool by 20%).
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Result: Goal
attained. Rentech and RNP completed the fiscal year ended September 30, 2011 with an OSHA recordable rate of approximately 2.6 recordable incidents for every 200,000 hours worked at Rentechs and RNPs facilities, which is well below
the industry average for comparable operations.



| | 2. | Goal: Total ammonia production ranging from approximately 230,000 tons to 280,000 tons, targeted at approximately 270,000 tons (2.5% weight).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------

Result: Goal attained above target level. Total ammonia production at our
facility in East Dubuque, Illinois for the fiscal year ending September 30, 2011 was approximately 273,000 tons.



| | 3. | Goal: Performance expectations including:
| | -- | -----------------------------------------



| |  |  | Consolidated EBITDA targeted at approximately $15.0 million (15% weight).
| | - |  | -------------------------------------------------------------------------

Result: Goal attained above target level. Consolidated EBITDA for the fiscal year ended September 30,
2011 was approximately $27.7 million.



| |  |  | RNP EBITDA targeted at approximately $63 million (5% weight).
| | - |  | -------------------------------------------------------------

Result: Goal attained above target level. RNP EBITDA for the fiscal year ended September 30, 2011 was
approximately $81.7 million.



| |  |  | Consolidated capital expenditures limit of approximately $49 million (2.5% weight).
| | - |  | -----------------------------------------------------------------------------------

Result: Goal attained better than target level. Consolidated capital expenditures for fiscal year ended
September 30, 2011 were approximately $42.4 million.



| | 4. | Goal: Raise capital proceeds, targeted at $50 million, sufficient to fund Rentechs budgeted activities and provide a year-end cash
cushion (10% weight).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------

Result: Goal partially attained. Rentech received a
distribution including approximately $47 million of new loan proceeds upon the closing of RNPs June 10, 2011 five year $150 million secured term loan facility.

| | 5. | Goal: Successful operation of Rentechs Product Demonstration Unit during 2011 that meets or exceeds performance criteria aimed at
improving the economic efficiency of the Rentech Process, targeted at operation for more than 30 days with acceptable catalyst usage levels (5% weight).
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Result:Goal partially attained. Rentech operated the Product Demonstration Unit for more than 30 days
during 2011; however, catalyst usage objectives and overall efficiency did not fully meet targets.



| | 6. | Goal: Construction and integration of the ClearFuels Gasifier at Rentechs Product Demonstration Unit on schedule, targeted at 75%
operational completion (5% weight).
| | -- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------

Result: Goal attained above target level.
Rentech had completed approximately 80% of this project as of September 30, 2011.



| | 7. | Goal: Close construction financing for Rentechs project in Rialto, California or an alternate project (25% weight) and secure funding
commitment and development milestones for an additional project (5% weight).
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Result: Goals not attained. Construction financing was not obtained for Rentechs Rialto project (or an
alternate project), nor was a funding commitment secured or development milestones established for an additional project.



| | 8. | Goal: Complete design of catalyst recipe that meets catalyst cost targets (5% weight).
| | -- | --------------------------------------------------------------------------------------

Result: Goal partially attained.



| | 9. | Goal: Other factors which contribute to the success of Rentech as determined by our Board of Directors, including the Boards subjective
assessment of the executives contributions to attaining the objective goals specified above (20% weight).
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Result: Determined on a case-by-case basis.

At the
end of each year (including fiscal year 2011), our Chief Executive Officer develops a scorecard based on his own assessment and input from other members of our senior management team that summarizes performance for each of his direct reports
(including the other NEOs) compared to the pre-established goals, taking into consideration any key accomplishments outside of the goals for the year. Satisfaction of each goal is evaluated on a scale ranging from zero (did not meet) to two
(exceptional performance) and the scorecard is then reviewed by our Compensation Committee and modified as appropriate in its discretion. Final incentive payments for our NEOs participating in the annual incentive program are determined based on a
combination of performance compared to the goals and the individuals contributions to our overall success during the year. Messrs. Ramsbottom, Cohrs, Samson, Wright and Morris received 2011 annual incentive payments equal to 50%, 50%, 40%, 40%
and 50% of their respective target bonuses based on the performance results described above. Mr. Miller left the Company in 2011 and received payment of his target bonus with respect to fiscal year 2011 pursuant to the terms of his employment
agreement. The actual 2011 annual incentive payments for our NEOs are set forth below under Summary Compensation Table.

Long-Term Equity Incentive Awards

The Compensation Committee and the Board of Directors believe that senior executives, including our NEOs, should have an ongoing stake in the success of their employer to closely align their interests
with those of its shareholders. Accordingly, long-term incentive equity awards covering shares of our common stock have historically been a key component of our compensation program, including during 2011, as these awards create an ownership stake
for management that aligns the interests of our NEOs with those of our shareholders and incentivize our NEOs to work toward increasing value for our shareholders. Our equity awards typically are issued under our 2006 and 2009 Incentive Award Plans
which are intended to provide incentives for a broad group of people including employees (both NEOs and rank-and-file), directors, consultants who are critical to the success of the Company and the creation of shareholder value.

During 2011, we granted awards of stock options and restricted stock units (RSUs) to our NEOs. RSUs create an
ownership stake aligned with the interests of shareholders. Stock options provide additional incentive to increase shareholder value. All of the equity-based awards vest over time or upon achievement of specific performance targets, creating both
retention and performance incentives.



14

##### Table of Contents

Our option awards are generally in the form of incentive stock options
(ISOs), which offer tax benefits if our NEOs satisfy statutory holding period requirements for the ISO shares after exercise (and certain other conditions are met), thereby providing an incentive for our NEOs to hold such shares and
further align their interests with those of our shareholders. However, a portion of the stock options granted to Messrs. Ramsbottom and Cohrs were granted as nonqualified stock options to comply with statutory ISO limits. We believe that this mix of
awards furthers our compensation objectives by incentivizing our NEOs to remain employed with us, to increase shareholder value and to hold our shares for an extended duration.

No annual equity awards were granted in fiscal year 2009 and more than 50% of the annual equity awards granted to our
NEOs in fiscal year 2010 were performance-based RSUs. All of our 2011 stock option and RSU grants vest in annual installments over a three-year period following the grant date, subject to the recipients continued employment with the Company,
except that a recipients award may vest on an accelerated basis upon certain qualifying terminations of employment or in connection with a change in control (as described under Potential Payments upon Termination or
Change-in-Control below). We believe that this vesting period provides an appropriate retention incentive, while accelerated vesting (where appropriate) protects executives against forfeiture of their awards in circumstances that are beyond
their control, and aligns managements incentives more closely with the interests of our shareholders.

In addition to these stock options and RSUs, Messrs. Ramsbottom, Cohrs and Morris received grants of phantom units, which
include distribution equivalent rights, from RNP, our subsidiary, in connection with their work on RNPs initial public offering. RNP phantom units were granted by RNP to reward these executives for their efforts in implementing RNPs
initial public offering, to compensate these executives for their services as officers of RNP following the offering, and to create incentives aligned with the interests of the unit holders of RNP. These phantom units vest in annual installments
over a three-year period and, like our equity awards, are intended to provide retention incentives linked to equity value and to encourage equity ownership in order to align the interests of these executives with those of RNPs unit holders
(including Rentech). For more information on these phantom unit grants, please see RNPs Annual Report on Form 10-K for the fiscal year ended September 30, 2011, filed with the SEC on December 14, 2011.

During fiscal year 2011, the Company issued a total of approximately 1,975,000 RSUs and 3,197,000 stock options to
members of management, including the NEOs. In determining appropriate levels of equity grants, our Compensation Committee considered, among other things, the role and responsibility of each NEO and the perceived need to reward and retain the NEO.
There were no shares allocated to our management stock purchase program in conjunction with the awards granted in the fiscal year ended September 30, 2011.

The table below sets forth the equity incentive awards that we granted to our NEOs during fiscal year 2011:

Employment Contracts; Severance Benefits

We believe that vulnerability to termination of employment at the senior executive level creates uncertainty for our NEOs
that is appropriately addressed by providing severance protections which enable and encourage these executives to focus their attention on their work duties and responsibilities in all situations. We operate in a volatile and acquisitive industry
that heightens this vulnerability in the change-in-control context. Accordingly, in order to attract and retain our key managerial talent, we enter into employment agreements with our NEOs which provide for specified severance payments and benefits
in connection with certain qualifying terminations of employment. We believe that terminations of employment, both within and outside of the change in control context, are causes of great concern and uncertainty for senior executives and that
providing protections to our named executives in these contexts is therefore appropriate in order to alleviate these concerns, and to enable and encourage the executives to focus their attention on their duties and responsibilities to the Company in
all situations. In addition, we believe that change in control and severance benefits are essential in order to fulfill our objective of attracting and retaining key managerial talent. As of September 30, 2011, Rentech was party to employment
agreements with Messrs. Ramsbottom, Cohrs, Samson, Wright and Morris. Mr. Miller did

not serve as an executive officer as of that date, but he received severance payments under the terms of his employment agreement upon his termination of employment on May 31, 2011. For a
description of the specific terms and conditions of each agreement, see Narrative Disclosure to Summary Compensation Table and Grants of Plan-Based Awards Table and Potential Payments upon Termination or
Change-in-Control below.

Benefits and Perquisites

We maintain a standard complement of health and retirement benefit plans for our employees, including our NEOs, that
provide medical, dental, and vision benefits, flexible spending accounts, a 401(k) savings plan (including an employer-match component), short-term and long-term disability insurance, accidental death and dismemberment insurance and life insurance
coverage. These benefits are generally provided to our NEOs on the same terms and conditions as they are provided to our other employees.

We believe that these health and retirement benefits comprise key elements of a comprehensive compensation program. Our health benefits help provide stability and peace of mind to our NEOs, thus enabling
them to better focus on their work responsibilities, while our 401(k) plan provides a vehicle for tax-preferred retirement savings with additional compensation in the form of an employer match that adds to the overall desirability of our executive
compensation package. Our employee benefits programs are designed to be affordable and competitive in relation to the market, as well as compliant with applicable laws and practices. We periodically review and adjust these employee benefits programs
as needed based upon regular monitoring of applicable laws and practices in the competitive market.

As part
of the compensation package, we also provide our NEOs with a monthly car allowance and these executives (other than Mr. Wright) also receive reimbursement of certain financial advisor costs. Mr. Samson received a one-time commencement
bonus in fiscal year 2011 as an incentive to join our company, as well as certain temporary living costs. We also provided our NEOs with supplemental group term life insurance coverage and life insurance during 2011. The Compensation Committee does
not believe that perquisites should play an important role in the compensation of our executives, but also believes that the limited benefits identified here are not a material component of our executive compensation program and are reasonable and
in line with those provided to similarly-situated executives in our field.

Tax and Accounting Considerations

Section 162(m) of the Internal Revenue Code

Generally, Section 162(m) of the Internal Revenue Code disallows a tax deduction to any publicly-held corporation for any individual remuneration in excess of $1 million paid in any taxable year to
its chief executive officer and each of its other named executive officers, other than its chief financial officer. However, remuneration in excess of $1 million may be deducted if it qualifies as performance-based compensation within
the meaning of the Internal Revenue Code.

Where reasonably practicable, to the extent that the
Section 162(m) deduction disallowance becomes applicable to our named executive officers, the compensation committee may seek to qualify the variable compensation paid to our named executive officers for an exemption from such deductibility
limitations. As such, in approving the amount and form of compensation for our named executive officers, the compensation committee will consider all elements of the cost to us of providing such compensation, including the potential impact of
Section 162(m) of the Internal Revenue Code. The compensation committee may, in its judgment, authorize compensation payments that do not comply with an exemption from the deductibility limit in Section 162(m) of the Internal Revenue Code
when it believes that such payments are appropriate to attract and retain executive talent.

Section 280G of the Internal Revenue Code

Section 280G of the Internal Revenue Code disallows a tax deduction with respect to excess parachute
payments to certain executives of companies which undergo a change in control. In addition, Section 4999 of the Internal Revenue Code imposes a 20% excise tax on the individual with respect to the excess parachute payment. Parachute payments
are compensation linked to or triggered by a change in control and may include, but are not limited to, bonus payments, severance payments, certain fringe benefits, and payments and acceleration of vesting from long-term incentive plans including
stock options and other equity-based compensation. Excess parachute payments are parachute payments that exceed a threshold determined under Section 280G of the Internal Revenue Code based on the executives prior compensation. In
approving compensation arrangements for our NEOs in the future, we expect to consider all elements of the cost of providing such compensation, including the potential impact of Section 280G of the Internal



16

##### Table of Contents

Revenue Code. However, we may authorize compensation arrangements that could give rise to loss of deductibility under Section 280G of the Internal Revenue Code and the imposition of excise
taxes under Section 4999 of the Internal Revenue Code if we feel that such arrangements are appropriate to attract and retain executive talent.

Under their employment agreements with us, our NEOs are entitled to gross-up payments in the event that any excise taxes are imposed on them. We have historically provided these protections to these
senior executives to ensure that they will be properly incentivized in the event of a potential change in control of Rentech to maximize shareholder value in a transaction while minimizing concern for potential consequences of the transaction to
these executives.

Section 409A of the Internal Revenue Code

Section 409A of the Internal Revenue Code requires that nonqualified deferred compensation be deferred
and paid under plans or arrangements that satisfy the requirements of the statute with respect to the timing of deferral elections, timing of payments and certain other matters. Failure to satisfy these requirements can expose employees and other
service providers to accelerated income tax liabilities, substantial additional taxes and interest on their vested compensation under such plans. Accordingly, as a general matter, it is our intention to design and administer our compensation and
benefit plans and arrangements for all of our employees and other service providers, including our NEOs, so that they are either exempt from, or satisfy the requirements of, Section 409A of the Internal Revenue Code.

Accounting for Stock-Based Compensation

We follow Financial Accounting Standards Board Accounting Standards Codification Topic 718, or ASC Topic 718, for stock-based compensation awards. ASC Topic 718 requires companies to calculate the grant
date fair value of their stock-based awards using a variety of assumptions. ASC Topic 718 also requires companies to recognize the compensation cost of their stock-based awards in their income statements over the period that an employee
is required to render service in exchange for the award. Grants of stock options, restricted stock, RSUs and other equity-based awards under equity incentive award plans have been and will be accounted for under ASC Topic 718. We expect that we will
regularly consider the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our equity incentive award plans and programs. As accounting standards change, we may revise certain
programs to appropriately align accounting expenses of our equity awards with our overall executive compensation philosophy and objectives.

The Role of Shareholder Say-on-Pay Votes

At our annual meeting of shareholders held in May 2011, we provided our shareholders with the opportunity to cast an advisory vote on our executive compensation program (a say-on-pay
proposal). A majority of the votes cast on our say-on-pay proposal at that meeting were voted in favor of the proposal. The Compensation Committee of the Board of Directors believes this affirms our shareholders support of our approach
to executive compensation, and, accordingly, did not change its approach to executive compensation in 2011 in connection with the say-on-pay proposal. The Compensation Committee expects to take into consideration the outcome of our
shareholders future say-on-pay proposal votes when making future compensation decisions for our NEOs. We expect that our next say-on-pay proposal will be submitted to shareholders for an advisory vote at our annual meeting of stockholders in
2014.

The Compensation Committee of the Board of Directors reviews our executive compensation program
annually to ensure that our NEOs compensation remains tied to the Companys long-term and short-term performance. The Company lists its goals and its performance with respect to such goals each year in its proxy statement and determines
any cash bonuses payable to its NEOs based on its assessment of the Companys performance against those goals, as described in more detail above under Annual Incentive Compensation. In 2011, the Company met some, but not all,
of its stated goals and as a result, all of the Companys current NEOs received 2011 annual bonuses equal to 50% or less of their target bonuses and their overall cash compensation decreased. In addition, the Companys long-term incentive
awards have historically been subject to performance based vesting requirements. No annual equity awards were granted to the Companys NEOs in fiscal year 2009 and over 60% (70% in the case of Mr. Ramsbottom) of the NEOs equity
awards in 2010 were performance-based awards tied directly to the achievement of milestones related to commercializing the Companys alternative energy technologies and building shareholder value. Each of these factors demonstrates a strong
alignment between performance and compensation for the Companys NEOs.

|(2) | Amounts reflect the aggregate grant date fair value of the stock and option awards, calculated in accordance with ASC Topic 718. We provide
information regarding the assumptions used to calculate the value of all of our stock awards made to executive officers in Note 15 to our consolidated financial statements included in the Original 10-K. There can be no assurance that awards will
vest or will be exercised, as applicable (in which case no value will be realized by the individual), or that the value upon vesting or exercise, as applicable, will approximate the aggregate grant date fair value determined under ASC
Topic 718. The amounts reported for fiscal year 2009 do not match the amounts reported in our 2009 compensation disclosure due to rule amendments which now require that we show the aggregate grant date fair value of these awards for all years.

|(3) | Each of our NEOs participates in our annual incentive program and received an annual incentive award based on the achievement of certain
pre-established financial and other performance criteria and determined by reference to target bonuses set forth in their respective employment agreements. The non-equity incentive amounts that were awarded in December 2011 and 2010 were paid 100%
in cash.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The non-equity incentive amounts that were awarded in December 2009 were payable
90% in cash, with the remaining 10% awarded in the form of RSUs which were issued in December 2009. The value of the RSUs awarded with the allocated portion of the 2009 non-equity incentive amounts is included in the Stock Awards column. The Company
made matching grants of RSUs to each named executive officer with a value equal to 10% of the NEOs 2009 non-equity incentive amounts in December 2009, which are also included in the Stock Awards column above.

|(1) | All equity grants to NEOs other than Mr. Ramsbottom were made under Rentechs 2009 Amended and Restated Incentive Award Plan.
Mr. Ramsbottoms RSU award and his two option awards covering 120,289 and 384,211 shares, respectively, were granted under Rentechs Amended and Restated 2006 Incentive Award Plan, as amended. Mr. Ramsbottoms option
covering 195,500 shares was granted under Rentechs 2005 Stock Option Plan. Amounts reflect the full grant date fair value of Rentech stock options or RSUs, as applicable, granted during the fiscal year ending September 30, 2011, computed
in accordance with ASC Topic 718, rather than the amounts paid to or realized by the named individual. We provide information regarding the assumptions used to calculate the fair value of all compensatory equity awards made to executive
officers in Note 15 to our consolidated financial statements included in the Original 10-K. There can be no assurance that awards will vest or will be exercised, as applicable (in which case no value will be realized by the individual), or that
the value upon vesting or exercise, as applicable, will approximate the aggregate grant date fair value determined under ASC Topic 718.

|(2) | These RSUs vest in three substantially equal installments on October 4, 2011, 2012 and 2013, subject to the executives continued
employment through the applicable vesting date and accelerated vesting in connection with (i) the executives termination of employment by the employer without cause or by the executive for good reason in connection with a change in
control of Rentech or (ii) the executives death or disability.

control of Rentech or (ii) the executives death or disability.

Employment Agreements

The employment agreements for
Messrs. Ramsbottom, Cohrs, Samson, Wright and Morris continue through December 31, 2012, October 22, 2012, October 5, 2012, November 3, 2012, and November 3, 2012, respectively, subject in each case to
automatic one-year renewals absent 90-days advance notice from either party to the contrary. Under these employment agreements, Messrs. Ramsbottom, Cohrs, Samson, Wright and Morris are entitled, respectively, to (i) current base
salaries, effective January 1, 2012, of $497,200, $426,575, $350,200, $286,350, and $288,030, and (ii) annual incentive bonuses targeted at 100%, 60%, 50%, 50% and 50% of applicable base salary (with actual bonus eligibility for each
executive ranging from zero to twice the applicable target). Mr. Samsons agreement entitles him to certain costs associated with Mr. Samsons relocation to Los Angeles, California, including transportation and moving expenses,
temporary housing expenses and a housing allowance payable during the first three years following his relocation. Mr. Millers employment agreement, which terminated on May 31, 2011, provided for a base salary of $351,500 per year and
an annual incentive bonus targeted at 50% of base salary.

The employment agreements entitle each executive to
a gross-up payment from the Company equal to any excise taxes that the executive incurs under Internal Revenue Code Section 280G (and any taxes on such gross-up payment) in connection with a change in control of the Company. In
addition, the employment agreements provide for monthly auto allowances, as well as customary indemnification, health, welfare, retirement and vacation benefits. The agreements also contain customary confidentiality and other restrictive covenants.
Each of the executives covered by an employment agreement has also executed a corporate confidentiality and proprietary rights agreement. Though not addressed in the employment agreements, each of the NEOs is entitled to accelerated vesting of
certain equity awards in the event of a change in control of Rentech. For a discussion of the severance and change-in-control benefits for which our NEOs are eligible under their employment agreements, see Potential Payments upon
Termination or Change-in-Control below.

Potential Payments upon Termination or Change-in-Control

The employment agreements of Messrs. Ramsbottom, Cohrs, Samson, Wright and Morris provide for severance payments upon
termination without cause, non-renewal of the executives employment agreement and the executives resignation for good reason. The employment agreements also provide for payments upon a termination without cause and executives
resignation for good reason in connection with a change in control at the Company. In addition, certain of the performance share and RSU agreements of Messrs. Ramsbottom, Cohrs, Samson, Wright and Morris identified in the tables below provide for
accelerated vesting upon the occurrence of certain of these same events, as described in detail below. In the event that any severance payments to Messrs. Ramsbottom, Cohrs, Samson, Wright and Morris are subject to federal excise taxes under the
golden parachute provisions of the Internal Revenue Code, Rentech is required to pay the executives a gross-up for any such excise taxes plus any excise, income or payroll taxes owed on the payment of the gross-up for the excise taxes.
No severance payments or accelerated vesting events are provided if an NEO is terminated for cause or resigns without good reason.

Termination Not in Connection with a Change in Control

Under the NEOs employment agreements, upon termination of the executives employment by Rentech without cause, by the executive with good reason or, in the case of Mr. Ramsbottom only, due
to a non-renewal of his employment term by Rentech (each as defined in the employment agreements), the executive is entitled to receive: (i) an amount equal to three times (in the case of Mr. Ramsbottom) or one times (in the case of the
remaining NEOs) base salary, payable in substantially equal installments over a two-year period (for Mr. Ramsbottom) or a one-year period (for the remaining NEOs), plus (ii) in the case of the remaining NEOs, payment of each
executives target annual bonus on the date that annual bonuses are paid generally for the year in which termination occurs, and (iii) company-paid continuation health benefits for up to eighteen months following the date of termination.
Upon termination of the remaining NEOs employment in connection with Rentechs non-renewal of their respective employment terms, they will be entitled to receive an amount equal to one times base salary, payable over the one-year period
following termination, and will be eligible to receive an annual bonus for the year of termination.

In
addition, the NEOs will be entitled to the following enhanced vesting provisions with respect to qualifying terminations occurring outside of the context of a change in control of Rentech:



| |  |  | The 2010 Options, 2010 RSUs, the 2009 Time-Vest RSUs and the Management Stock Purchase Plan RSUs held by the executive will accelerate and vest in
full upon a termination of employment due to the applicable executives death or disability.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The 2009 Performance-Vest RSUs held by the executive will, following the executives termination due to his death or disability, remain
outstanding and eligible to vest for a period of six months following such termination and will vest if and to the extent that applicable vesting milestones are attained during such period.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | The Cohrs Inducement RSU will vest upon Mr. Cohrs termination (i) without cause or for good reason, as to the number of shares for
which the RSU would have vested over the twelve-month period immediately following such termination had Mr. Cohrs remained employed, and (ii) due to Mr. Cohrs death or disability, on an accelerated basis with respect to all
shares subject to the RSU.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Samson Inducement RSU will, upon Mr. Samsons termination due to death or disability, vest on an accelerated basis with respect to all
shares subject to the RSU.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

Change in Control (No Termination)

The NEOs are not entitled to any cash payments based solely on the occurrence of a change in control of Rentech (absent
any qualifying termination), however, the following enhanced vesting provisions will apply: the NEOs will be entitled to full accelerated vesting upon such change in control with respect to their Management Stock Purchase Plan RSUs. The 2010
Options, 2010 RSUs, 2009 Time-Vest RSUs, 2009 Performance-Vest RSUs and Samson Inducement RSU are not impacted by a change in control of Rentech (absent a qualifying termination in connection with such change in control).

Termination in Connection with a Change in Control

If the NEOs terminate employment without cause, for good reason or due a non-renewal of his employment term by Rentech,
in any case, within three months before or two years after a change in control of Rentech, then the terminated executive will receive the severance described above, except that (i) the base salary component of the executives severance
will be paid in a lump sum and (ii) if the executives actual annual bonus for the year immediately preceding the change in control exceeds his target bonus for the year in which the termination occurs, (A) in the case of
Mr. Ramsbottom, he will receive two times base salary plus the amount of such prior-year bonus (instead of three times his base salary) and (B) in the case of the remaining NEOs, each NEO will receive one times base salary plus the amount
of such prior-year bonus (instead of base salary plus target annual bonus). The NEOs employment agreements entitle each of these executives to a gross-up payment from Rentech covering all taxes, penalties and interest associated
with any golden parachute excise taxes that are imposed on the executives by reason of Internal Revenue Code Section 280G in connection with a change in control of Rentech.

In addition, the NEOs will be entitled to the following enhanced vesting provisions with respect to qualifying
terminations occurring in connection with a change in control of Rentech:



| |  |  | The 2010 Options, the 2010 RSUs and the 2009 Time-Vest RSUs will vest in full if the executive terminates employment without cause or for good
reason, in either case, within sixty days prior to or one year after the change in control.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | As noted above, the Management Stock Purchase Plan RSUs held by the executive will vest in full upon the change in control (without regard to
whether the executive terminates employment).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The 2009 Performance-Vest RSUs held by the executive will remain outstanding and eligible to vest for a period of six months following the
executives termination without cause or for good reason, in either case, occurring within sixty days prior to or one year after the change in control, and these RSUs will vest if and to the extent that applicable vesting milestones are
attained during such period.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Cohrs Inducement RSU will vest in full if a change in control occurs within two months after Mr. Cohrs termination of employment
without cause or for good reason (in addition to vesting in full if the change in control occurs while Mr. Cohrs remains employed).
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The Samson Inducement RSU will vest in full following his termination without cause or for good reason, in either case, occurring within sixty days
prior to or one year after the change in control.

Directors who are employees of Rentech do not receive
additional compensation for their services on the Board. The compensation plan for nonemployee directors provides for an annual retainer of $30,000 to be paid in $7,500 quarterly increments to each outside director. The Chairman of the Board
receives an additional fee of $25,000 per year. Additional cash compensation is provided for participation in committees of the Board, up to a maximum of $15,000 per year for all committee work. The Chairman of the Audit Committee receives $15,000
per year; the Chairman of the Compensation and the Chairman of the Nominating Committee receive $7,500 per year; and regular committee members receive $5,000 per year. Directors are reimbursed for reasonable out-of-pocket expenses incurred in their
capacity as directors. No additional cash fees are paid to directors for attendance at Board or committee meetings.

Each newly elected non-employee member of the Board is granted a five-year, fully-vested option to purchase 20,000 shares of the Companys common stock at the fair market value of the Companys
common stock on the date of grant. Each non-employee director serving immediately following the Companys annual meeting of shareholders also is granted the number of shares of fully vested Company common stock obtained by dividing $50,000 by
the fair market value of the Companys common stock on the date of grant, rounded up to the nearest 100 shares. Each non-employee director serving immediately following the Companys annual meeting of shareholders also is granted a RSU
with a vesting period of one year equal in value to $25,000 based on the Black-Scholes option-pricing model at an exercise price equal to the fair market value of a share of the Companys common stock on the date of grant, determined in
accordance with our Incentive Plan. The stock option will vest in a single installment on the earlier of the one year anniversary of the date of grant and the Companys annual meeting of shareholders, subject to the directors continued
Board service through such date.

Compensation Committee Interlocks and Insider Participation

During fiscal year 2011, the following individuals served as members of the Compensation Committee: Michael S. Burke,
Halbert S. Washburn, and Edward M. Stern. None of these individuals has ever served as an officer or employee of the Company or any of its subsidiaries. No executive officer of the Company has served as a director or member of the compensation
committee of another entity at which an executive officer of such entity is also a director of the Company.

Mr. Williams was a greater than 10% stockholder of SilvaGas when it was
acquired by the Company in June of 2009 pursuant to the terms of an Agreement and Plan of Merger (the Merger Agreement). In addition to the consideration paid at the closing, the former SilvaGas stockholders were entitled to receive
additional shares of the Companys common stock as earn-out consideration. In addition, approximately 6,800,000 of the shares of our common stock issuable at closing were be deposited with an escrow agent to support certain indemnification
obligations of the SilvaGas stockholders. Fifty percent of the escrow shares were to be released after two years if no claims were made against them and the remaining fifty percent were to be released after three years. No claims have been made to
date and fifty percent of the escrow shares were released in December 2010 in exchange for extending the survival date of certain of the SilvaGas stockholders representations, warranties and covenants by an additional six months.

On December 28, 2011 the Company entered into Amendment No. 2 (the Amendment) to the Merger
Agreement with Milton Farris, as Stockholder Representative, John A. Williams and certain other former stockholders of SilvaGas. Pursuant to the terms of the Amendment, the parties agreed to amend the Merger Agreement to: (a) release the
remaining 3,409,092 shares of Company common stock held in escrow pursuant to the terms of the Merger Agreement and its associated escrow agreement, on or prior to December 31, 2011; (b) provide for the payment of 2.0 million shares
of Company common stock by March 31, 2012 to the former stockholders of SilvaGas in satisfaction of all potential earn-out payments provided for in the Merger Agreement; and (c) provide for a release of the Company by the former
stockholders of SilvaGas from all claims they may have related to the Merger Agreement and its associated transactions and documents.
