 THIS WARRANT CERTIFIES THAT for
value received, Mercator Momentum Fund, LP, or its registered assigns (hereinafter called the “Holder”) is entitled to purchase from Rentech, Inc. (hereinafter called the “Company”), the above
referenced number of fully paid and nonassessable shares (the “Shares”) of common stock (the “Common Stock”), of Company, at the Warrant Price per Share referenced above; the number of shares
purchasable upon exercise of this Warrant referenced above being subject to adjustment from time to time as described herein. This Warrant is issued in connection with that certain Subscription Agreement dated as of April 8, 2005, by and between the
Company and Holder (the “Subscription Agreement”). The exercise of this Warrant shall be subject to the provisions, limitations and restrictions contained herein. 
  
 Term and Exercise. 
  
 Term. This Warrant is exercisable in whole or in part (but not as to any fractional share of Common Stock), at any time that is more than 91 days after the
date of this Warrant and from time to time thereafter prior to 6:00 p.m. on the Expiration Date set forth above. 
  
 Warrant Price. The Warrant shall be exercisable at the Warrant Price described above. 
  
 Maximum Number of Shares. The maximum number of Shares of Common Stock exercisable pursuant to this Warrant is as set forth
above, except for adjustments pursuant to Section 3 of this Warrant. However, notwithstanding anything herein to the contrary, in no event shall the Holder be permitted to exercise this Warrant for a number of Shares greater than the number that
would cause the aggregate beneficial ownership of the Company’s Common Stock (calculated pursuant to Rule 13d-3 of the Securities Exchange Act of 1934, as amended) of (a) the Holder and its affiliates or (b) M.A.G. Capital, LLC, and its
affiliates, to equal 9.99% of the Company’s Common Stock then outstanding.  
  
 Procedure for Exercise of Warrant. Holder may exercise this Warrant by delivering the following to the principal office of the Company in accordance with Section 5.1 hereof: (i) a duly executed Notice of Exercise in
substantially the form attached as Schedule A, (ii) payment of the Warrant Price then in effect for each of the Shares being purchased, as designated in the Notice of Exercise, and (iii) this Warrant. Payment of the Warrant Price may be in cash,
certified or official bank check payable to the order of the Company, or wire transfer of funds to the Company’s account (or any combination of any of the foregoing) in the amount of the Warrant Price for each share being purchased. 

  
 Delivery of Certificate and New Warrant. In the event of any
exercise of the rights represented by this Warrant, a certificate or certificates for the 

  

 Page 1 








 
shares of Common Stock so purchased, registered in the name of the Holder or such other name or names as may be designated by the Holder, together with any
other securities or other property which the Holder is entitled to receive upon exercise of this Warrant, shall be delivered to the Holder hereof, at the Company’s expense, within a reasonable time, not exceeding fifteen (15) calendar days,
after the rights represented by this Warrant shall have been so exercised; and, unless this Warrant has expired, a new Warrant representing the number of Shares (except a remaining fractional share), if any, with respect to which this Warrant shall
not then have been exercised shall also be issued to the Holder hereof within such time. The person in whose name any certificate for shares of Common Stock is issued upon exercise of this Warrant shall for all purposes be deemed to have become the
holder of record of such shares on the date on which the Warrant was surrendered and payment of the Warrant Price was received by the Company, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and
payment is on a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such Shares at the close of business on the next succeeding date on which the stock transfer books are
open. 
  
 Restrictive Legend. Each certificate for Shares
shall bear a restrictive legend in substantially the form as follows, together with any additional legend required by (i) any applicable state securities laws and (ii) any securities exchange upon which such Shares may, at the time of such exercise,
be listed: 
  
 The shares of stock evidenced by this
certificate have not been registered under the U.S. Securities Act of 1933, as amended, and may not be offered, sold, pledged or otherwise transferred (“transferred”) in the absence of such registration or an applicable exemption
therefrom. In the absence of such registration, such shares may not be transferred unless, if the Company requests, the Company has received a written opinion from counsel in form and substance satisfactory to the Company stating that such transfer
is being made in compliance with all applicable federal and state securities laws. 
  
 Any certificate issued at any time in exchange or substitution for any certificate bearing such legend shall also bear such legend unless, in the opinion of counsel for the Holder thereof (which counsel shall be reasonably satisfactory to
the Company), the securities represented thereby are not, at such time, required by law to bear such legend. 
  
 Fractional Shares. No fractional Shares shall be issuable upon exercise or conversion of the Warrant. In the event of a fractional interest, the number of Shares to be issued shall be rounded down to the
nearest whole Share.  
  
 Representations, Warranties and
Covenants. 
  
 Representations and Warranties. 

 
 The Company is a corporation duly organized, validly existing and in good standing under
the laws of its state of incorporation and has all necessary power and authority to perform its obligations under this Warrant; 
  
 The execution, delivery and performance of this Warrant has been duly authorized by all necessary actions on the part of the Company and constitutes the legal, valid and
binding obligation of the Company, enforceable against the Company in accordance with its terms; and 
  
 This Warrant does not violate and is not in conflict with any of the provisions of the Company’s Articles of Incorporation or Certificate of Determination, Bylaws and any resolutions of the Company’s Board
of Directors or stockholders, or any agreement of the Company, and no event has occurred and no condition or circumstance exists that might (with or without notice or lapse of time) constitute or result directly or indirectly in such a violation or
conflict. 
  
 Issuance of Shares. The Company covenants and agrees
that all shares of Common Stock that may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be validly issued, fully paid and nonassessable, and free from all

	  	Page 2









 
taxes, liens and charges with respect to the issue thereof. The Company further covenants and agrees that it will pay when due and payable any and all
federal and state taxes which may be payable in respect of the issue of this Warrant or any Common Stock or certificates therefor issuable upon the exercise of this Warrant. The Company further covenants and agrees that the Company will at all times
have authorized and reserved, free from preemptive rights, a sufficient number of shares of Common Stock to provide for the exercise in full of the rights represented by this Warrant. If at any time the number of authorized but unissued shares of
Common Stock of the Company shall not be sufficient to effect the exercise of the Warrant in full, subject to the limitations set forth in Section 1.3 hereto, then the Company will take all such corporate action as may, in the opinion of counsel to
the Company, be necessary or advisable to increase the number of its authorized shares of Common Stock as shall be sufficient to permit the exercise of the Warrant in full, subject to the limitations set forth in Section 1.3 hereto, including
without limitation, using its best efforts to obtain any necessary stockholder approval of such increase. The Company further covenants and agrees that if any shares of capital stock to be reserved for the purpose of the issuance of shares upon the
exercise of this Warrant require registration with or approval of any governmental authority under any federal or state law before such shares may be validly issued or delivered upon exercise, then the Company will in good faith and as expeditiously
as possible endeavor to secure such registration or approval, as the case may be. If and so long as the Common Stock issuable upon the exercise of this Warrant is listed on any national securities exchange or the Nasdaq Stock Market, the Company
will, if permitted by the rules of such exchange or market, list and keep listed on such exchange or market, upon official notice of issuance, all shares of such Common Stock issuable upon exercise of this Warrant. 
  
 Other Adjustments. 
  
 Subdivision or Combination of Shares. In case the Company shall at any time
subdivide its outstanding Common Stock into a greater number of shares, the Warrant Price in effect immediately prior to such subdivision shall be proportionately reduced, and the number of Shares subject to this Warrant shall be proportionately
increased, and conversely, in case the outstanding Common Stock of the Company shall be combined into a smaller number of shares, the Warrant Price in effect immediately prior to such combination shall be proportionately increased, and the number of
Shares subject to this Warrant shall be proportionately decreased. 
  
 Dividends in Common Stock, Other Stock or Property. If at any time or from time to time the holders of Common Stock (or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) shall
have received or become entitled to receive, without payment therefor: 
  
 Common
Stock, Options or any shares or other securities which are at any time directly or indirectly convertible into or exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of
dividend or other distribution; 
  
 any cash paid or payable otherwise than as a
regular cash dividend; or 
  
 Common Stock or additional shares or other
securities or property (including cash) by way of spin-off, split-up, reclassification, combination of shares or similar corporate rearrangement (other than Common Stock issued as a stock split or adjustments in respect of which shall be covered by
the terms of Section 3.1 above) and additional shares, other securities or property issued in connection with a Change (as defined below) (which shall be covered by the terms of Section 3.4 below), then and in each such case, the Holder hereof
shall, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and
property (including cash in the cases referred to in clause (b) above and this clause (c)) which such Holder would hold on the date of such exercise had

	  	Page 3









 
such Holder been the holder of record of such Common Stock as of the date on which holders of Common Stock received or became entitled to receive such shares
or all other additional stock and other securities and property. 
  
 Reorganization, Reclassification, Consolidation, Merger or Sale. If any recapitalization, reclassification or reorganization of the share capital of the Company, or any consolidation or merger of the Company with another
corporation, or the sale of all or substantially all of its shares and/or assets or other transaction (including, without limitation, a sale of substantially all of its assets followed by a liquidation) shall be effected in such a way that holders
of Common Stock shall be entitled to receive shares, securities or other assets or property (a “Change”), then, as a condition of such Change, lawful and adequate provisions shall be made by the Company whereby the Holder hereof
shall thereafter have the right to purchase and receive (in lieu of the Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such shares, securities or other assets or
property as may be issued or payable with respect to or in exchange for the number of outstanding Common Stock which such Holder would have been entitled to receive had such Holder exercised this Warrant immediately prior to the consummation of such
Change. The Company or its successor shall promptly issue to Holder a new Warrant for such new securities or other property. The new Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to give effect to
the adjustments provided for in this Section 3 including, without limitation, adjustments to the Warrant Price and to the number of securities or property issuable upon exercise of the new Warrant. The provisions of this Section 3.3 shall similarly
apply to successive Changes. 
  
 Notwithstanding the previous provisions of this
Section, if the Company is a party to a merger with another entity, and if, immediately after the merger, the persons who were shareholders of the Company immediately before the transaction will not own a majority of the outstanding voting
securities of the surviving entity in substantially the same proportions as they owned the outstanding voting securities of the Company before the transaction, then the holder shall receive for this Warrant in the merger, in complete satisfaction of
all rights hereunder, the amount and kind of securities, cash or other property that such Holder would have received in the merger if this Warrant had been exercised in full immediately before the merger, less a portion thereof having a fair market
value, as determined in good faith by the Board of Directors of the Company, equal to the Warrant Price that would have been payable upon such exercise. 
  
 Ownership and Transfer. 
  
 Ownership of This Warrant. The Company may deem and treat the person in whose name this Warrant is registered as the holder and owner hereof
(notwithstanding any notations of ownership or writing hereon made by anyone other than the Company) for all purposes and shall not be affected by any notice to the contrary until presentation of this Warrant for registration of transfer as provided
in this Section 4. 
  
 Transfer and Replacement. This Warrant and
all rights hereunder are transferable in whole or in part upon the books of the Company by the Holder hereof in person or by duly authorized attorney, and a new Warrant or Warrants, of the same tenor as this Warrant but registered in the name of the
transferee or transferees (and in the name of the Holder, if a partial transfer is effected) shall be made and delivered by the Company upon surrender of this Warrant duly endorsed, at the office of the Company in accordance with Section 5.1 hereof.
Upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft or destruction, and, in such case, of indemnity or security reasonably satisfactory to it, and upon surrender of this Warrant if mutilated, the Company will
make and deliver a new Warrant of like tenor, in lieu of this Warrant; provided that if the Holder hereof is an instrumentality of a state or local government or an institutional holder or a nominee for such an instrumentality or institutional
holder an irrevocable agreement of indemnity by such Holder shall be sufficient for all purposes of this Warrant, and no evidence of loss or theft or destruction shall be necessary. This Warrant shall be promptly

	  	Page 4









 
cancelled by the Company upon the surrender hereof in connection with any transfer or replacement. Except as otherwise provided above, in the case of the
loss, theft or destruction of a Warrant, the Company shall pay all expenses, taxes and other charges payable in connection with any transfer or replacement of this Warrant, other than income taxes and stock transfer taxes (if any) payable in
connection with a transfer of this Warrant, which shall be payable by the Holder. Holder will not transfer this Warrant and the rights hereunder except in compliance with federal and state securities laws and except after providing evidence of such
compliance reasonably satisfactory to the Company.

shareholder of the Company except upon exercise in accordance with the terms hereof. No provision hereof, in the absence of affirmative action by the Holder to purchase shares of Common Stock, and no mere enumeration herein of the rights or
privileges of the Holder, shall give rise to any liability of the Holder for the Warrant Price hereunder or as a shareholder of the Company, whether such liability is asserted by the Company or by creditors of the Company. 
  
 Governing Law. This Warrant shall be governed by and construed in accordance
with the laws of the State of California as applied to agreements among California residents made and to be performed entirely within the State of California, without giving effect to the conflict of law principles thereof.

party to serve process in any other manner permitted by law. Each of the parties agrees that a final non-appealable judgment in any such suit or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on such judgment or in
any other lawful manner.
