17th Street, Suite 720, Denver, CO 80202. RDC and RCR are
from time to time hereafter referred to individually as a “Party” and collectively as the “Parties.” 

W I T N E S S E T H: 

WHEREAS, RCR’s parent company, Royster-Clark, Inc. (“RCI”), formerly owned and operated, through its ownership of
Royster-Clark Nitrogen, Inc., a facility (the “Facility”) located in East Dubuque, Illinois at which it manufactured anhydrous ammonia, granular urea, nitric acid, UAN solutions and carbon dioxide (“Products”) for sale to its
industrial and agri-business customers; and 
 WHEREAS, on the date hereof, RDC acquired the Facility, through its purchase of
Royster-Clark Nitrogen, Inc. from RCI, with a view to converting the Facility over a period of approximately three (3) years to utilize alternative feedstock and to co-produce synthetic fuels with ammonia; and 

WHEREAS, RDC wishes to sell anhydrous ammonia, granular urea, UAN solutions and nitric acid and related nitrogen-based products
(“Facility Products”) manufactured at the Facility to 

 
RCR and to engage RCR as its exclusive distributor of the Facility Products for agricultural and industrial use within the United States; and 

WHEREAS, RCR wishes to purchase the Facility Products and to act as RDC’s exclusive distributor of the Facility Products under the
terms and conditions set forth herein; and 
 WHEREAS, RCR is a major distributor of nitrogen products and has historically
sourced up to 25% of its need from the Facility. 
 NOW, THEREFORE, in consideration of the premises and of the mutual covenants
and obligations contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties agree as follows: 
 ARTICLE I 
 APPOINTMENT AND TERMS OF DISTRIBUTORSHIP 

1.1 Appointment. RDC hereby appoints RCR as its exclusive distributor for the sale, purchase and resale of the Facility Products
for agricultural and industrial use throughout the United States subject to the terms and conditions of this Agreement. 
 1.2
Relationship of the Parties. The relationship between RDC and RCR is that of independent contractors and not that of employer-employee or principal-agent. RCR shall not be the agent or legal representative of RDC, nor shall RDC be the agent
or legal representative of RCR. Neither RDC nor RCR shall have the right, power or authority to assume or undertake any obligation whatsoever or make any representation on behalf of the other unless authorized to do so in writing. 

1.3 Commercially Reasonable Efforts. 
 Subject to the terms and conditions of this Agreement (including, without limitation, Sections 1.4, 1.5 and 2.1), (i) RCR agrees to use its commercially reasonable efforts to promote the

  
 2 

 
sale of, and to solicit and secure orders for the Facility Products from its customers, particularly its customers within the “truck market” area around the Facility, and to purchase
from RDC all Facility Products manufactured at the Facility, and (ii) RDC agrees to sell to RCR all of its requirements of the Facility Products. Notwithstanding the foregoing, in no event shall RDC be required to manufacture and deliver to RCR
more than that amount of Facility Product that RDC and RCR have agreed that RCR shall purchase from RDC pursuant to Section 2.1. It is expressly understood and agreed that RCR may purchase Facility Products hereunder for its own account as well
as for resale to its customers. In addition, RCR may accept deliveries of Facility Products from RDC on consignment in RCR’s terminals upon such terms and conditions as the Parties may agree, including but not limited to the terms set forth in
Article III. 
 1.4. Third Party Sales. In the event that RCR and RDC are not able to reach an agreement during the
Negotiation Period (as defined below) with respect to a transaction proposed under either of Sections 2.1(a) or 2.1(b), then RDC shall have the right to sell to third parties the same Facility Products that were the subject of such proposed
transaction; provided that any such sale to a third party (each, a “Third Party Sale”) must satisfy each of the following conditions: (a) such Facility Products shall only be sold and shipped on the same timetable and in
the same volume as were included in the terms of the last proposal in writing by RDC to RCR during the Negotiation Period with respect to such proposed transaction and (b) such Facility Products shall only be sold at a price (taking into
account rebates and similar items, if any) not less than the lowest price included in such proposal (the price at which such Facility Products are actually sold to a third party being the “Third Party Price” with respect thereto).
Notwithstanding the foregoing, RCR shall receive the Applicable Commission based on the Third Party Price of any Third Party Sale, except that in the case of Third Party Sales to New Customers (as defined below) RCR shall not receive

  
 3 

 
any commission under this Section 1.4. “New Customers” shall mean persons/entities (i) to which RCR shall not have sold any Facility Products during the five (5) year
period ending immediately prior to such Third Party Sale and (ii) having “ship-to points” that are different from the “ship-to point” of any person who would not be a New Customer under the foregoing clause (i).
Notwithstanding anything to the contrary herein, RDC shall have the exclusive right to market and sell Facility Products for agricultural or industrial end-use outside the United States. 

1.5 Inventory. Subject to Section 2.1, no specific minimum purchase obligations on the part of RCR shall be established in
connection with its inventory of Facility Products or otherwise, and no specific minimum production obligations on the part of RDC with respect to the Facility Products shall be established under this Agreement. 

1.6 Inspection. (a) RDC shall have the right, from time to time, upon at least fourteen (14) days’ prior written
notice to RCR, to inspect, during regular business hours, RCR’s books and records relating to sales of Facility Products to its customers, for the purpose of determining the accuracy of the “Applicable Commission,” as subsequently
defined in this Agreement, provided that RDC shall use its best efforts to minimize any disruption to RCR’s business resulting from such inspection. 
 (b) RCR shall have the right, from time to time, upon at least fourteen (14) days’ prior written notice to RDC, to inspect, during regular business hours, RDC’s books and records relating
to sales of Facility Products to third parties (including with respect to rebates and similar items, if any), for the purposes of determining whether Third Party Sales by RDC were made in compliance with Section 1.4 and whether the reporting
thereof was accurate. 
 1.7 Sales Forecasts. RCR and RDC shall cooperate and use their commercially reasonable efforts
to prepare and mutually agree upon, on or before September 1 of each year (or, 

  
 4 

 
during the first year of the Term, within 30 days after the date hereof, for the calendar year immediately following, a 12-month forecast of RCR’s Sales of Facility Products (“Sales
Forecast”) under a format to be mutually agreed upon by the parties. It is understood and agreed, however, that such forecasts shall be estimates only, and shall not constitute a commitment by RCR to purchase, nor RDC to produce, the amount of
Facility Products identified in the Sales Forecast. RCR and RDC shall cooperate and use their commercially reasonable efforts to mutually agree upon updates to the Sales Forecast prior to each calendar quarter. The parties intend to cooperatively
develop marketing and promotion plans to maximize sales of the Facility Products. RCR and RDC agree that they will in be in regular contact with one another such that RCR shall keep RDC reasonably well-apprised of the third-party market for Facility
Products and RDC shall keep RCR reasonably well-apprised of its levels of production and inventory of Facility Products. 
 1.8
RDC Sales. RDC shall not, directly or indirectly, sell any Facility Products for agricultural or industrial use within the United States other than to or through RCR or through Third Party Sales. Notwithstanding anything herein to the
contrary, RDC reserves the right to sell carbon dioxide, fuels, electricity and sulfur and any other product produced at the Facility other than Facility Products and RCR shall not be entitled to receive any commission or other compensation on, or
any other rights in respect of, any such sales pursuant to this Agreement. 
 ARTICLE II 

PURCHASE ORDERS, PRICE, PAYMENT AND DELIVERY TERMS 
 2.1 Placement of Orders and Shipping. (a) To the extent RCR desires to purchase Facility Products from RDC, RCR shall so notify RDC and include with such notice details as to the type and
quantity of Facility Products, the timing of delivery and the pricing terms with respect to which it desires to make such purchase. 

  
 5 

 (b) To the extent RDC desires to sell Facility Products to RCR, RDC shall so notify RCR and
include with such notice details as to the type and quantity of Facility Products, the timing of delivery and the pricing terms with respect to which it desires to make such sale. 

(c) In each circumstance in which Section 2.1(a) or Section 2.1(b) is implicated, RCR or RDC, as the case may be, shall have
two (2) business days to respond to the other (the “Offer Period”). In the case of Section 2.1(a), if RDC shall not have responded within the Offer Period, it shall be deemed to have rejected the terms of the purchase proposed by
RCR. In the case of Section 2.1(b), if RCR shall not have responded within the Offer Period, it shall be deemed to have rejected the terms of the sale proposed by RDC. In the event that RCR fails to respond during the Offer Period or either RCR
or RDC, as the case may be, responds that it will not agree to the proposed transaction, then the two shall negotiate in good faith, for a period not to exceed two (2) business days (the “Negotiation Period”), seeking to reach
agreement on the terms of the proposed transaction. During the Negotiation Period and with respect to pricing terms, the parties shall take into consideration (among other factors) the preceding two weeks FOB Midwest Market Prices for the particular
product as published by Fertilizer Week America (FOB Midwest) and Green Markets (Mid Cornbelt). If RCR and RDC shall agree on the terms of the proposed transaction during the Offer Period or the Negotiation Period, the agreed price with respect to
that transaction (the “Sales Price”), less the Applicable Commission, shall be payable with respect thereto under Section 2.4. 
 (d) If RDC is unable to ship on a timely basis the Facility Products that are required by an agreed transaction, it will so notify RCR and inform it of the anticipated shipping date, and if shipment is
not made within five (5) days after the shipping date specified with respect to such agreed transaction, RCR shall have the right to cancel such agreed transaction without prejudice to any other right or remedy of RCR.

 2.2 Delivery of Facility Products. Except as set forth in Article III, delivery of
the Facility Products to RCR or its customer shall be FOB the Facility in East Dubuque, Illinois, and title to and risk of loss of Facility Products shall pass upon delivery to RCR or its customer when the Facility Products pass the flange into
RCR’s or its customer’s barge, truck or railcar. RCR shall arrange and pay for shipping of Facility Products hereunder. Collection of freight from its customers shall be RCR’s responsibility. However, RDC acknowledges that RCR may
wish to have RDC (at RCR’s sole cost and expense) ship Facility Products to RCR or its customers from time to time. Purchases of anhydrous ammonia made by RCR out of the NIOTA Facility (as defined below) shall be made at the same price as
though such purchases were FOB the Facility in East Dubuque plus the actual freight costs incurred in moving such Facility Products from East Dubuque to the NIOTA Facility. 
 2.3 Applicable Commission. As used herein, the “Applicable Commission” shall mean with respect to transactions for which the Sales Price or the Third Party Price is agreed during the
following periods: (a) from the date of this Agreement until the date that is one year from the date hereof, 2.00% of the applicable Sales Price or Third Party Price, (b) for the second year of the Term, 3.0% of the applicable Sales Price
or Third Party Price, (c) for the third year of the Term, 4.0% of the applicable Sales Price or Third Party Price, (d) for the fourth year of the Term and each year of the Term thereafter through the tenth year of the Term, 5.0% of the
applicable Sales Price or Third Party Price and (e) for each subsequent one (1) year renewal period, such percentage of the applicable Sales Price or Third Party Price as RDC and RCR shall negotiate and agree in good faith at least thirty
(30) days before the commencement of such twelve (12) month period. Notwithstanding the foregoing, the maximum amount of the Applicable Commission payable by RDC to RCR hereunder shall not exceed $5,000,000 with

  
 7 

 
respect to any of the ten (10) twelve-month periods ending on the first ten (10) anniversaries of the date hereof. 

2.4 Payment. (a) RDC shall, on a weekly basis, deliver to RCR a written statement (hereinafter referred to as the
“Shipping Statement”) showing all Facility Products shipped to RCR or its customers during the preceding one week period. RCR shall remit to RDC within thirty (30) days from the date of Shipping Statement, by wire transfer, an amount
equal to such amount indicated on the Shipping Statement. The Shipping Statement amount will be based on the applicable Sales Prices less the Applicable Commission. No Shipping Statement need be delivered if during the applicable week no Facility
Products were shipped as described above. 
 (b) RCR shall on a weekly basis deliver to RDC a statement (hereinafter referred to
as the “Sales Statement”) for all sales of Facility Product that RDC has placed on consignment in RCR’s terminals for the preceding one week period. The Sales Statement shall list all sales based on the terms and conditions agreed to
at the time Facility Product was placed on consignment with RCR. RCR shall remit to RDC within thirty (30) days from the date of Sales Statement, by wire transfer, an amount equal to such amount indicated on the Sales Statement. No Sales
Statement need be delivered if during the applicable week no Facility Products were placed on consignment as described above. 

(c) RDC shall, on a weekly basis, deliver to RCR a written statement (hereinafter referred to as the “Third Party Sales
Statement”) showing all Facility Products shipped through Third Party Sales during the preceding one week period. RDC shall remit to RCR within thirty (30) days from the date of Third Party Sales Statement, by wire transfer, an amount
equal to such amount indicated on the Third Party Sales Statement. The Third Party Sales Statement amount will be the Applicable Commission based on the applicable Third Party Prices. No Third Party Sales

  
 8 

 
Statement need be delivered if during the applicable week no Third Party Sales were made. 
 (d) It is understood and agreed that RCR shall bear the credit risk on all resales of Facility Products to its customers, and that the purchase price payable by RCR to RDC for Facility Products hereunder
shall be based upon the Sales Price, less the Applicable Commission, regardless of whether or when such amounts are actually collected by RCR. Notwithstanding anything herein to the contrary, RDC shall bear the credit risk on all Third Party Sales.

 2.6 Use of Facility. RDC covenants and agrees that during any period in which RDC shall have shut-down or ceased the
production of Facility Products at the Facility for a period of thirty (30) or more consecutive days, either (i) the Facility shall be used for some purpose(s) other than the provision of customary fertilizer terminal services or
(ii) if the Facility is not so put to use during such period, RDC shall commence negotiations with RCR in good faith so as to provide RCR with a reasonable opportunity to utilize the Facility on an exclusive basis as a terminal (including,
without limitation, RDC providing customary fertilizer terminal services to RCR at such fee-rate and on such other terms as are reasonably negotiated by the parties based upon then prevailing industry standards). In no event shall RDC allow a third
party to utilize the Facility as a fertilizer terminal on terms less favorable to RDC than the least favorable terms made available in writing to RCR. 
 ARTICLE III 
 TERMINAL SERVICES 

3.1 Terminal Services. (a) During the Storage Term (as defined in Section 3.2) RDC shall purchase and pay for, and RCR
shall provide, Terminal Services (as defined below) on the terms and conditions set forth herein. 
 (i) The Maximum Storage
Quantity with respect to any one July 1 to June 30 period during the Storage Term (“Maximum SQ”) shall be: 30 kst; provided, that, the maximum 

  
 9 

 
storage quantity that RCR shall have any obligation to provide hereunder at any given time (the “Current Limit”) shall be 15 kst minus the volume of anhydrous ammonia then
being stored at the NIOTA Facility (x) which is then owned by RDC or any of its affiliates or (y) which was sold to RCR within the prior 60 days. 
 (ii) The Minimum Storage Quantity with respect to any one July 1 to June 30 period during the Storage Term (“Minimum SQ”) shall be: 30 kst. 

“Terminal Services” shall consist of the facility as set forth on Exhibit A (the “NIOTA Facility”) for the receipt of
anhydrous ammonia up to the Maximum SQ at the Receipt Point (as defined on Exhibit A), the storage of the anhydrous ammonia and the delivery of an equivalent quantity of anhydrous ammonia at the Point of Delivery (as defined on Exhibit
A) on a firm basis, in each case, subject to and in accordance with the terms and conditions set forth herein. 
 (b) RDC
shall notify RCR in writing (including by facsimile or electronic mail) (the “Storage Notice”) at least ten (10) business days prior to the date on which RDC desires the transport to the NIOTA Facility for storage to begin with
respect to an amount of anhydrous ammonia, which amount shall be specified by RDC in the Storage Notice. Transportation shall be arranged pursuant to Section 3.4. Load-in at the NIOTA Facility of such anhydrous ammonia shall be based upon
available load-in capacity of the NIOTA Facility determined pro rata on the basis of the volume of storage space occupied by RDC’s anhydrous ammonia as compared to the aggregate storage space then occupied. 

(c) For all inventory-related purposes contemplated by this Article III, the amount of anhydrous ammonia placed in storage from barges
shall be determined by a destination certified independent shore tank survey. The amount of anhydrous ammonia delivered out of storage shall be determined from certified scale weights when delivered into

  
 10 

 
tanker trucks or by a destination certified independent shore tank survey when delivered into barges. 
 3.2 Storage Term. (a) Unless this Agreement is earlier terminated pursuant to Section 5.1, RCR shall provide and RDC shall pay for the Terminal Services from July 1, 2006 until
June 30, 2011 or such other end date as may be provided under Section 3.2(b) (the “Storage Term,” and each period from July 1 to June 30 of any year during the Storage Term, a “Storage Year”). 

(b) Unless cancelled by RDC by giving RCR three (3) months written notice of such cancellation prior to June 30, 2011, RCR
shall continue to provide and RDC shall pay for the Terminal Services for the five (5) year period after June 30, 2011 (unless this Agreement is terminated pursuant to Section 5.1). Subsequently, unless cancelled by RDC by giving RCR
three (3) months of written notice of such cancellation prior to the expiration of each successive June 30, the Storage Term shall renew until the termination of this Agreement pursuant to Section 5.1. Notwithstanding anything else
set forth herein, the Storage Term shall terminate no later than the termination of this Agreement in accordance with Section 5.1. If the Agreement shall terminate on a date other than June 30 of any given year, then all calculations and
requirements with respect to the Storage Year during which the Agreement is terminated shall be reduced proportionally based on the quotient obtained by dividing the actual number of days elapsed in that Storage Year by 365. 

3.3 Terminal Services Fees. (a) In consideration for Terminal Services up to the Maximum SQ, RCR shall invoice RDC monthly as
described in Section 3.3(c) below for (i) RDC’s Pro Rata Share of the direct on-site, full operating costs (whether fixed and/or variable) for that month plus (ii) a $25,000 per month fixed fee, provided that, at the end of each
Storage 

  
 11 

 
Year in the event RDC has not used the Minimum SQ for such Storage Year, RDC shall pay RCR for the difference between (x) the Pro Rata Share of the costs for Terminal Services assuming RDC
had used Terminal Services with respect to the full Minimum SQ less (y) the Pro Rata Share of the costs of Terminal Services actually paid by RDC under Section 3.3(a) (such calculation is referred to herein as the
“Reconciliation”). By way of illustration, Schedule 3.3 hereto sets forth the items included in a calculation of direct on-site, full operating costs (whether fixed or variable). 

(b) RDC and RCR shall negotiate in good faith to determine the Terminal Service Fees for the storage of any amounts of anhydrous ammonia
in excess of the Maximum SQ; provided, that the provision of Terminal Services hereunder by RCR in excess of the Maximum SQ with respect to any Storage Year shall be at the sole and absolute discretion of RCR. 

“Pro Rata Share” shall mean the ratio, expressed as a percentage, the numerator of which shall be the aggregate amount of
anhydrous ammonia stored at the NIOTA Facility by RDC during the prior month (or the prior Storage Year for purposes of calculating the Reconciliation) and the denominator of which shall be the total throughput for the NIOTA Facility during the
prior month (or the prior Storage Year for purposes of calculating the Reconciliation). 
 (c) RCR shall, on a monthly basis,
deliver to RDC a written statement (the “Storage Invoice”) showing (i) the total throughput of all anhydrous ammonia stored at the NIOTA Facility in the prior month with line items for the amount of anhydrous ammonia stored on behalf
of RDC and the amount of anhydrous ammonia stored on behalf of all other parties, including RCR and (ii) RDC’s Pro Rata Share of the total anhydrous ammonia stored that month at the NIOTA Facility and (iii) the amount owed by RDC for
the Terminal Services used as calculated pursuant to Section 3.3(a), which amount shall be due and payable within thirty (30)

  
 12 

 
days from the date of the Storage Invoice. 
 3.4 Freight Costs.
RCR shall use commercially reasonable efforts to arrange for (with RDC’s approval), and RDC shall pay for the cost of delivery of the anhydrous ammonia to the NIOTA Facility for storage on RDC’s behalf pursuant to this Article III. The
cost of deliveries of anhydrous ammonia from the NIOTA Facility shall be borne by the owners of such product. 
 3.5 Level of
Service. In providing the Terminal Services, RCR agrees to operate and maintain the NIOTA Facility in accordance with: (a) this Agreement and applicable law; and (b) Prudent Industry Practice. As used herein, the term “Prudent
Industry Practice” shall mean practices, methods, standards and acts customarily employed by skilled and experienced owners, operators or maintainers of terminals for storing anhydrous ammonia in North America and which are similar in size and
operational characteristics to the NIOTA Facility, exercising that degree of skill, diligence, prudence and foresight which would reasonably and ordinarily be expected from such owners, operators and maintainers and complying with all applicable
laws and customary industry practices. 
 3.6 Failure to Receive Anhydrous Ammonia. RCR shall use commercially reasonable
efforts to provide the Terminal Services. In the event that RCR is unable to receive any anhydrous ammonia that RDC proposes to store at the NIOTA Facility pursuant to a Storage Notice because of technical or mechanical problems, to the extent that
(x) such amount when aggregated with all other anhydrous ammonia stored by RDC at the NIOTA Facility in the then current Storage Year does not exceed the Maximum SQ and (y) storage of such amount would not cause the Current Limit to be
exceeded, such amount shall be credited towards the Minimum SQ for that Storage Year. 

  
 13 

 3.7 Risk of Loss; Title. RDC shall bear the risk of loss for and retain title to its
anhydrous ammonia with respect to which RCR is providing Terminal Services, provided that, if any portion of RDC’s anhydrous ammonia is lost or damaged due to the negligence, willful misconduct or breach of this Agreement by RCR or any persons
acting on RCR’s behalf, then RCR shall be responsible for the entire cost of repairing or replacing any such loss or damage. For the avoidance of doubt, RCR shall bear the risk of loss for and retain title to any anhydrous ammonia stored at the
NIOTA Facility at such time as RCR agrees to purchase such product. 
 3.8 Access. RCR shall provide RDC, its agents and
it customers with reasonable access to the NIOTA Facility. RDC shall have the right to remove its stored anhydrous ammonia at the Point of Delivery based upon available load-out capacity of the NIOTA Facility determined pro rata on the basis of the
volume of storage space occupied by RDC’s anhydrous ammonia as compared to the aggregate storage space then occupied 
 3.9
Shrinkage. In connection with the actions contemplated by this Article III, RCR will be entitled up to one percent (1.0%) shrinkage allowance (the “Shrinkage Allowance”) of the volume of anhydrous ammonia received during a
Storage Year against any shortage, loss or damage occurring during that Storage Year. The Shrinkage Allowance shall be deducted from the agreed receipts by RCR of anhydrous ammonia. At the end of each Storage Year, RCR shall promptly pay RDC for any
such shortage, loss or damage that is in excess of the Shrinkage Allowance; it being understood that under no circumstances will RCR be allowed to carry over any portion of the credit not used in any given Storage Year. The value or price of the
anhydrous ammonia to be used in arriving at any sum due under this Section 3.9 shall be RDC’s published wholesale price FOB East Dubuque Illinois of the anhydrous ammonia involved at the end of such Storage Year. 

  
 14 

 ARTICLE IV

Section 11 below to the contrary, the amendment of the term “Pro Rata Share” as contemplated in Section 10(a) above shall become effective concurrently with the execution of this Amendment.
