or both) (i) violate any provision of any judgment, ruling, order, writ, injunction or decree applicable to such Purchaser; or (ii) violate any provision of any state, federal or local law, rule or regulation applicable to such Purchaser.
This Agreement, and the Related Agreements to which such Purchaser is a party, have been duly executed and delivered by such Purchaser. Assuming due execution and delivery thereof by the other parties hereto or thereto, this Agreement and the
Related Agreements will each be a valid and binding obligation of such Purchaser enforceable against such Purchaser in accordance with its terms, except as such enforceability may be limited by applicable laws relating to bankruptcy, insolvency,
reorganization, moratorium or other similar legal requirement relating to or affecting creditors’ rights generally and except as such enforceability is subject to general principles of equity (regardless of whether enforceability is considered
in a proceeding in equity or at law). 
 Section 3.3 Government Approvals. No consent, approval, license or authorization of, or
filing with, any Governmental Authority is required on the part of such Purchaser in connection with the execution, delivery and performance by such Purchaser of this Agreement and the Related Agreements to which it is a party, except for:

(a) Such Purchaser is an “accredited investor” as that term is defined in Rule 501(a) of Regulation D promulgated under the
Securities Act.

public offering and under similar exemptions under certain state securities laws, that this transaction has not been reviewed by, passed on or submitted to any federal or state agency or self-regulatory organization where an exemption is being
relied upon, and that the Company’s reliance thereon is based in part upon the representations made by such Purchaser in this Agreement and the Related Agreements. Such Purchaser acknowledges that it has been informed by the Company of, or is
otherwise familiar with, the nature of the limitations imposed by the Securities Act and the rules and regulations thereunder on the transfer of securities.

 (e) The Company
has provided to such Purchaser all documents and information that such Purchaser has requested relating to an investment in the Company. Such Purchaser recognizes that investing in the Company involves substantial risks, and has taken full
cognizance of and understands all of the risk factors related to the acquisition of the Purchased Shares. Such Purchaser has carefully considered and has, to the extent it believes such discussion necessary, discussed with the Purchaser’s
professional legal, tax and financial advisers the suitability of an investment in the Company, and such Purchaser has determined that the acquisition of the Purchased Shares is a suitable investment for the Purchaser. Such Purchaser has not relied
on the Company for any tax or legal advice in connection with the purchase of the Purchased Shares. In evaluating the suitability of an investment in the Company, such Purchaser has not relied upon any representations or other information (other

 ARTICLE IV 

COVENANTS OF THE PARTIES 

Section 4.1 Board of Directors. 

(a) The Purchasers collectively shall have the right to appoint up to two directors to the Board of Directors (each, a “Series E
Director”) to the extent provided in the Articles of Amendment. 

  
 -11- 








 (b) In addition to the right described in Section 4.1(a), for so long as the
Purchasers in the aggregate have record and beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of Conversion Shares that constitute at least 10% of the outstanding Common Stock of the Company, the Purchasers’
collectively shall have the right to nominate one person for election to the Board of Directors (a “Purchaser Nominee”) once every three years. For so long as the Purchasers in the aggregate have record and beneficial ownership
(within the meaning of Rule 13d-3 under the Exchange Act) of Conversion Shares that constitute more than 18% of the outstanding Common Stock and less than 42.5% of the Series E Preferred Stock issued on the date of this Agreement, the Purchasers
collectively shall be entitled to nominate a total of two Purchaser Nominees for election to the Board of Directors once every three years; provided that such nominations may not be made in the same year. If the Purchasers have the right to
so nominate one or more Purchaser Nominees in a given year, the Company shall, at the annual meeting of the shareholders of the Company during such year, nominate the Purchaser Nominee(s) for election to the Board of Directors and use reasonable
efforts to cause the Purchaser Nominee(s) to be elected to the Board of Directors; provided, however, that each Purchaser Nominee shall be reasonably acceptable to the Nominating and Corporate Governance Committee of the Board of
Directors and shall comply with the Corporate Governance Guidelines of the Company as in effect from time to time. If, following election to the Board of Directors, a Purchaser Nominee resigns, is removed, is not re-elected or is otherwise unable to
serve for any reason and the Purchasers still have the right to nominate such Purchaser Nominee, then, the Purchasers collectively shall be entitled to designate a replacement Purchaser Nominee, and the Board of Directors shall, subject to the
exercise of their fiduciary duties, elect such replacement Purchaser Nominee to the Board of Directors. In the event that the Purchasers in the aggregate cease to hold the minimum percentage of the outstanding Common Stock that entitles them to
nominate a Purchaser Nominee as provided above, if requested by the Board of Directors, the Purchasers shall use reasonable best efforts to have such Purchaser Nominee resign as a director. As a pre-condition to the nomination of a Purchaser
Nominee, such Purchaser Nominee shall execute and deliver to the Board of Directors an irrevocable letter of resignation to be deemed tendered at the time the Purchasers are required to use reasonable best efforts to have him or her so resign. For
the avoidance of doubt, only Conversion Shares shall be counted towards whether the Purchasers meet such minimum percentages and, in the event that the Purchasers’ holdings of Conversion Shares drop below such a minimum percentage, they will
not regain the right to nominate a Purchaser Nominee through the acquisition of other shares of Common Stock. 
 (c) If the Purchasers are
entitled to appoint two Series E Directors, or to appoint at least one Series E Director and to nominate at least one Purchaser Nominee, in accordance with Section 4.1(a) and (b), one such Series E Director or Purchaser Nominee
shall satisfy all independence and other requirements of membership on the Board of Directors imposed by the Nasdaq Stock Market Rules (other than the requirements of Rule 10A-3(b)(1)(ii) under the Exchange Act). 

(d) For so long as the Purchasers have the right to appoint or nominate at least one person to the Board of Directors in accordance with this
Section 4.1, the Purchasers collectively shall have the right to appoint one observer (the “Observer”) to the Board of Directors who shall be reasonably acceptable to the Company. The Observer shall be permitted to
attend and observe all meetings (other than executive sessions) of the Board of Directors. The Observer shall not have the right to vote on any matter that comes before the Board of Directors. The Observer shall receive copies of all written
materials distributed to the Board of Directors and shall receive notice of each meeting or action by written consent of the Board of Directors at the same time and in the same manner as notice is given to the Board of Directors. Notwithstanding the
foregoing, the Company shall be entitled to withhold any information from the Observer and exclude the Observer from any meeting, or any portion thereof, (i) if the Company reasonably determines that such withholding or exclusion is necessary
to preserve attorney-client privilege, to protect highly confidential competitively sensitive information or for other similar reasons, or (ii) if the Company believes in good faith that the Observer has a conflict of interest. The Observer
shall execute a confidentiality agreement in form and substance reasonably acceptable to the Company and such Observer with respect to the information and discussions to which the Observer will have access. 

  
 -12- 








 (e) Notwithstanding the foregoing provisions of this Section 4.1, the Purchasers
shall exercise any right to appoint or nominate the Purchaser Nominees and the Observer by and through the Purchasers’ Representative, and the Company shall be permitted to communicate with the Purchasers’ Representative regarding all such
matters. 
 Section 4.2 Restrictions on Transfer. 

(a) After the Closing, no Purchaser shall Transfer any of the Purchased Shares to any Person (other than pursuant to the Articles of Amendment
or a Put Option Agreement) without the prior written consent of the Company, which shall not be unreasonably withheld, delayed or conditioned; provided, however, that, without the prior written consent of the Company, a Purchaser may
Transfer Purchased Shares to a Permitted Transferee of the Purchaser that agrees to be bound by the terms of this Article IV pursuant to a written agreement in form and substance reasonably satisfactory to the Company (and upon such Transfer
the Permitted Transferee shall become a “Purchaser” for purposes of this Article IV). 
 (b) From and after the time that
the Tax Benefit Preservation Plan (or any replacement or successor plan thereto) is no longer in effect, and so long as the Company has at least $25,000,000 of NOLs which may be carried forward for Federal income Tax purposes (as reflected in the
Company’s most recent public reports filed with the SEC), without the prior written consent of the Company, which shall not be unreasonably withheld, delayed or conditioned, no Purchaser shall knowingly (after reasonable inquiry) Transfer any
Conversion Shares to any Person or “group” (within the meaning of Section 13(d)(3) of the Exchange Act) that, immediately following such Transfer, would beneficially own in the aggregate 5% or more of the outstanding Common Stock,
other than (i) to a Permitted Transferee that agrees to be bound by the terms of this Article IV pursuant to a written agreement in form and substance reasonably satisfactory to the Company (and upon such Transfer the Permitted Transfer
shall become a “Purchaser” for purposes of this Article IV), (ii) to an underwriter in connection with a bona fide public offering or (iii) pursuant to regular way brokerage transactions in which the purchaser is not
identified. 
 (c) In order to provide for the orderly sale of any Common Stock by the Purchasers, the Purchasers shall not sell on any day
an aggregate number of shares of Common Stock in excess of 25% of the average daily trading volume of the Common Stock for the preceding three months on the national securities exchange on which it is traded, except pursuant to an underwritten
offering of the Common Stock in a registration effected by the Company pursuant to Article II of the Registration Rights Agreement. 
 (d)
Any attempted Transfer in violation of this Section 4.2 shall be void ab initio. 

  
 -13- 








 (e) Notwithstanding the foregoing, the restrictions in Section 4.2(b) and
(c) shall terminate and be of no further force or effect when the Purchasers, in the aggregate, cease to have record or beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of more than 5% of the outstanding
shares of the Company’s Common Stock (which shall be determined assuming conversion of all of the shares of Series E Preferred Stock). 

Section 4.3 Restrictive Legends. 

(a) Each certificate representing the Purchased Shares or, book-entry representing the Conversion Shares (unless otherwise permitted by the
provisions of Section 4.3(d)) shall bear a legend in the following form (in addition to any legend required under applicable state securities laws): 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED OR THE SECURITIES LAWS OF ANY
STATE MAY NOT BE TRANSFERRED, SOLD, OR OTHERWISE DISPOSED OF EXCEPT WHILE A REGISTRATION STATEMENT RELATING THERE TO IS IN EFFECT UNDER SUCH ACT OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT OR SUCH LAWS.” 

(b) In addition, for so long as the Purchased Shares or the Conversion Shares are subject to the restrictions set forth in
Section 4.2, each certificate representing the Purchased Shares or book-entry representing Conversion Shares (as applicable) shall bear a legend in the following form: 

“THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A SUBSCRIPTION AGREEMENT. THE COMPANY WILL MAIL TO
THE HOLDER OF THIS CERTIFICATE A COPY OF SUCH SUBSCRIPTION AGREEMENT, AS IN EFFECT ON THE DATE OF MAILING, WITHOUT CHARGE, PROMPTLY AFTER RECEIPT OF A WRITTEN REQUEST THEREFOR.” 

(c) Each Purchaser consents to the Company making a notation on its records and giving instructions to any transfer agent of the Purchased
Shares or the Conversion Shares in order to implement the restrictions on transfer set forth in this Section 4.3. 

  
 -14- 








 (d) Prior to any proposed Transfer of any Restricted Securities, unless there is in effect a
registration statement under the Securities Act covering the proposed Transfer, a Purchaser shall give written notice to the Company of such Purchaser’s intention to effect such Transfer. Each such notice shall describe the manner and
circumstances of the proposed Transfer in sufficient detail, and shall be accompanied by either (i) an opinion of legal counsel reasonably satisfactory to the Company to the effect that the proposed Transfer of the Restricted Securities may be
effected without registration under the Securities Act, or (ii) any other evidence reasonably satisfactory to counsel to the Company, whereupon such Purchaser shall be entitled to Transfer such Restricted Securities in accordance with the terms
of the notice delivered by such Purchaser to the Company. Notwithstanding the foregoing, in the event a Purchaser shall give the Company a representation letter containing such representations as the Company shall reasonably request, the Company
will not require such legal opinion or such other evidence (A) in a routine sales transaction in compliance with Rule 144 under the Securities Act, (B) in any transaction in which a Purchaser that is a corporation distributes Restricted
Securities solely to its majority owned subsidiaries or Affiliates for no consideration, (C) in any transaction in which a Purchaser that is a partnership or limited liability company distributes Restricted Securities solely to its Affiliates
(including affiliated fund partnerships), or partners or members of such Purchaser or its Affiliates for no consideration or (D) in a Transfer of Purchased Shares or Conversion Shares in compliance with Section 4.2(a) or
4.2(b). Each certificate evidencing the Restricted Securities transferred shall bear the appropriate restrictive legend set forth in Section 4.3 above, except that such certificate shall not bear the first such restrictive legend
if such legend is not required in order to establish compliance with any provisions of the Securities Act. Upon the request of a Purchaser of a certificate bearing the first such restrictive legend and, if necessary, the appropriate evidence as
required by clause (i) or (ii) above, the Company shall remove the first such restrictive legend from such certificate and from the certificate to be issued to the applicable transferee if such legend is not required in order to establish
compliance with any provisions of the Securities Act and the Purchaser promptly Transfers the Purchased Shares or Conversion Shares. Upon the request of a Purchaser that holds a certificate bearing the second restrictive legend, the Company shall
remove such restrictive legend from such certificate when the provisions of Section 4.2 are no longer applicable to the applicable Purchased Shares or Conversion Shares. 

Section 4.4 Standstill. 

(a) Each Purchaser agrees that until the first (1st) anniversary of the date of this Agreement (the “Restricted Period”),
without the prior written consent of the Company, it will not at any time, nor will it cause or permit any of its Affiliates to, make any public proposal to acquire or acquire, directly or indirectly, by purchase or otherwise, record or beneficial
ownership (within the meaning of Rule 13d-3 under the Exchange Act), of any additional shares of the Company’s Common Stock (other than Conversion Shares and any other shares directly issued by the Company); provided, however,
that if, at any time, the Purchasers, in the aggregate, have record or beneficial ownership of less than 10% of the outstanding shares of the Company’s Common Stock determined on a fully diluted basis, then the Purchasers, in the aggregate, may
acquire record or beneficial ownership of additional shares of the Company’s Common Stock, so long as the Purchasers, in the aggregate, do not have record or beneficial ownership of 10% or more of the outstanding shares of the Company’s
Common Stock determined on a fully diluted basis. Notwithstanding the foregoing, if the Company takes any direct or indirect action that results in the number of shares of Common Stock outstanding being reduced (e.g. stock repurchases), no Purchaser
shall be deemed to have breached this Section 4.4(a) as a result of such action. 

  
 -15- 








 (b) During the Restricted Period without the prior written consent of the Company, each Purchaser
agrees not to, directly or indirectly: 
 (i) publicly propose to enter into, directly or indirectly, any merger,
consolidation, business combination or other similar transaction involving the Company; 
 (ii) make, or in any way
participate in, any solicitation of proxies to vote any securities of the Company under any circumstances in connection with a merger or acquisition of the Company, or deposit any securities of the Company in a voting trust or subject them to a
voting agreement or other agreement of similar effect (it is understood and agreed that this clause (ii) shall not prohibit any Purchaser from voting any securities of the Company in its sole discretion); 

(iii) form, join or in any way participate in a “group” (within the meaning of Section 13(d)(3) of the Exchange
Act) with respect to any of securities of the Company, other than a group including solely the Purchasers and their Affiliates; 

(iv) disclose any intention, plan or arrangement to change any of the members of the Board of Directors (other than pursuant to
its rights hereunder or pursuant to the Articles of Amendment), any of the executive officers of the Company or the Articles of Incorporation or Bylaws of the Company, other than to the Company, directors of the Company or the Purchasers’
representatives and advisors (it is understood and agreed that this clause (iv) shall not prohibit any Purchaser from voting any securities of the Company in its sole discretion); 

(v) call, request the calling of, or otherwise seek the calling of a special meeting of the shareholders of the Company; 

(vi) publicly disclose any intention, plan or arrangement inconsistent with the foregoing, or 

(vii) advise, assist or encourage any other Persons in connection with any of the foregoing; 

it being understood that nothing in this Section 4.4(b) shall restrict or prohibit the Series E Directors, or any other representative of the
Purchasers who is a director of the Company, from taking any action, or refraining from taking any action, which he or she determines, in his or her reasonable discretion, is necessary to fulfill his or her fiduciary duties as a member of the Board
of Directors. 
 Section 4.5 Hedging Transactions. Each Purchaser agrees that it will not enter into any Hedging Transactions;
provided, however, that (a) if the Trading Price is more than two times the Conversion Price for at least 30 consecutive Trading Days immediately prior to a Hedging Transaction, then such Purchaser may enter into such Hedging
Transaction (other than any Short Sale) and (b) the restrictions in this Section 4.5 shall terminate and be of no further force or effect when the Purchasers, in the aggregate, cease to have record and beneficial ownership (within
the meaning of Rule 13d-3 under the Exchange Act) of more than 5% of the outstanding shares of the Company’s Common Stock (which shall be determined assuming conversion of all of the shares of Series E Preferred Stock). 

  
 -16- 








 Section 4.6 Use of Proceeds. The Company shall use the proceeds from the sale of the
Purchased Shares (together with the proceeds from the related term loan) (a) to pay off the indebtedness under and terminate the Credit Agreement, dated as of September 23, 2013, among Rentech Nitrogen Holdings, Inc., Credit Suisse AG,
Cayman Islands Branch, as administrative agent, and each other lender from time to time party thereto, (b) to fund the development or acquisition by the Company of wood pellet and wood fibre projects and associated expenses of the
Company’s wood fibre business, (c) to pay for the fees and expenses incurred by the Company in connection with the transactions contemplated by this Agreement and the Related Agreements and (d) general corporate purposes. The Company
shall not use such proceeds for any purpose that would result in the applicability of the federal margin stock rules in connection with the Purchased Shares. 

Section 4.7 [Intentionally Omitted.]  

Section 4.8 Blackstone. 

(a) Notwithstanding anything to the contrary set forth in this Agreement, none of the terms or provisions of this Agreement shall in any way
limit the activities of The Blackstone Group L.P. or any of its business units other than those within its credit business segment (collectively, the “Blackstone Group”), so long as (a) no member of the Blackstone Group is
acting on behalf of or in concert with any Purchaser with respect to any matter that otherwise would violate any term or provision of this Agreement, (b) no member of the Blackstone Group (other than any member of a Blackstone Group legal or
compliance team) has received any Confidential Information from a Purchaser, a Series E Director or a Purchaser Nominee, and (c) the Company’s securities are included on the Blackstone Group’s restricted securities or watch securities
list. 
 (b) The Company recognizes that the Purchasers are investment funds and managed accounts and that the Purchasers, their partners or

“Purchaser Group Member”) invest in, serve on the board of directors and other governing boards of, serve as officers of, provide services to and have minority and controlling ownership interests in existing and future operating or
portfolio companies. Nothing in this Agreement or the nature of the existing or any future relationship between the Purchaser Group or any Purchaser Group Member, on the one hand, and the Company or any of its Affiliates, on the other hand, will
prohibit the Purchaser Group or any Purchaser Group Member from engaging in any activity or business opportunity, including any activity or business opportunity that competes with or relates to the business conducted by the Company, that is
independently developed by such Purchaser Group or Purchaser Group Member without information obtained from, or the participation of, the Company or its Subsidiaries. Nothing in this Section 4.8(b) shall limit or qualify the fiduciary
duties of the Series E Directors or Purchaser Nominees to the Company or its shareholders.

 (b) If, after the Closing Date, the Company intends to issue New Securities for cash to any
Person, then, at least 10 Business Days prior to the issuance of the New Securities, the Company shall deliver to the Purchasers an offer (the “Offer”) to issue the New Securities to them upon the terms set forth in this
Section 4.11; provided, however, that the Company shall have no obligation to make an Offer unless at such time (i) the Purchasers, in the aggregate, have record and beneficial ownership (within the meaning of Rule
13d-3 under the Exchange Act) of more than 5% of the outstanding shares of the Company’s Common Stock (which shall be determined assuming conversion of all of the shares of Series E Preferred Stock), and (ii) the Trading Price has not
exceeded the Closing Price for the thirty Trading Days ending on the last day of the month immediately preceding the month in which the contemplated closing of the issuance of New Securities occurs. Notwithstanding the foregoing, the Company in its
discretion may voluntarily provide an Offer to the Purchasers even if the foregoing conditions have not been satisfied. The Offer shall state that the Company proposes to issue the New Securities and shall specify their number and terms (including
purchase price). Any Offer may contemplate market flex terms for the issuance of the New Securities. The Offer shall remain open and irrevocable for a period of 10 Business Days (the “Offer Period”) from the date of its delivery.

 (c) The Purchasers collectively shall have the right to purchase all but not less than all of the New Securities on the terms and
conditions set forth in the Offer by delivering written notice of acceptance thereof to the Company during the Offer Period. The closing of the purchase of New Securities by the Purchasers shall be held at the principal office of the Company at
11:00 a.m. local time on the closing date set forth in the Offer or at such other time and place as the parties to the transaction may agree. At such closing, the Company shall deliver the New Securities to the Purchasers against payment of the
purchase price therefor by the Purchasers. At such closing, all of the parties to the transaction shall execute such additional documents as are otherwise necessary or appropriate to consummate such transactions. 

(d) If the Purchasers do not elect to purchase all of the New Securities pursuant to Section 4.11(c), the Company may sell the New
Securities on terms and conditions that are no more favorable in the aggregate to the applicable purchaser than those set forth in the Offer. If such sale is not consummated within 120 days of the date upon which the Offer is given, then no issuance
of New Securities may be made thereafter by the Company without again offering the same to the Purchasers in accordance with this Section 4.11. 

(e) The rights granted in this Section 4.11 are personal to the Purchasers and their Permitted Transferees and do not constitute a
right of holders of any securities of the Company, including, without limitation, the Series E Preferred Stock, as such.
