Effective on the date hereof, the SPA is hereby amended to add to the end of Article 4 as follows:

“4.12 Acknowledgement and Direction

Pursuant to Section 4.3 of the SPA, Atlanta acknowledges and confirms to Green Bay that it has reviewed and approved the final form of the CFL Purchase Agreement and hereby provides its consent and approval of the CFL Purchase Agreement and directs Green Bay to cause Target, upon the Acquisition of Control and the implementation of the amalgamation of Bidco and Target, to implement the terms of the CFL Purchase Agreement including the payment of the Purchase Price (as defined in the CFL Purchase Agreement) to Green Bay, as agent for Target. Atlanta and Green Bay agree that the Closing (as defined in the CFL Purchase Agreement) of the transaction contemplated by the CFL Purchase Agreement shall constitute the Asset Closing for the Wholesale Business for all purposes of the SPA.

4.13 CFL Purchase Price Direction

Within two Business Days (as defined in the CFL Purchase Agreement) prior to the expected Closing Date (as defined in the CFL Purchase Agreement) Atlanta shall confirm to Green Bay the amount of the Purchase Price (as defined in the CFL Purchase Agreement) and provide payment instructions for Atlanta to Green Bay. Immediately prior to Closing, Green Bay shall irrevocably direct CFI to pay the proceeds from the sale of the Wholesale Business to Atlanta in accordance with Section 4.14 and in accordance with the instructions provided by Atlanta.

Atlanta acknowledges that, as a consequence of directing Green Bay to enter into the CFL Purchase Agreement and complete the transactions contemplated therein, the Retail

2

Business will lose the benefit of the Member Nitrogen Agreement (as defined in the CFL Purchase Agreement) and Green Bay shall accept from time to time such replacement nitrogen in the operation of the Retail Business as Atlanta shall instruct in writing. The loss of such benefit, any replacement nitrogen and any direct or indirect consequences thereof shall not be considered in determining whether Article 8 – Covenants Regarding Interim Operation or any other representation, warranty or covenant of Green Bay under the SPA has been breached or whether any condition precedent has been satisfied.

4.17 Claim to be made under CF Environmental Indemnity before Atlanta Indemnity

Prior to a Green Bay Indemnified Party making a Claim under Section 13.2 for which indemnification is available to such Green Bay Indemnified Party under any environmental indemnification provided by the Third Party purchaser of the Wholesale Business pursuant to Section 4.3, such Green Bay Indemnified Party shall first make the Claim under such environmental indemnification.

4.18 Purchase Price Allocation

Atlanta and Green Bay hereby agree that the Purchase Price (as defined in the CFL Purchase Agreement) shall be allocated [redacted] to the transfer of the Member Nitrogen Agreement (as defined in the CFL Purchase Agreement) and the balance to the Wholesale Business other than the Member Nitrogen Agreement. Neither Atlanta nor Green Bay, nor any of their respective Affiliates, shall take any tax position on any tax return, audit or otherwise that is inconsistent with such allocation.”

ARTICLE 3

AMENDMENTS TO THE SUPPORT AND PURCHASE AGREEMENT

Effective on the date hereof, the SPA is hereby further amended as follows:

3.1 The definition of “Assumed Liabilities” in Schedule 1.1 – Definitions to the SPA is amended to add the following at the end of such definition:

3

Within 30 days of the filing by Target of its Canadian tax return under the Tax Act for the taxation year in which the disposition of the Member Nitrogen Agreement occurs, Green Bay shall provide to Atlanta a statement of the Tax Adjustment. If the Tax Adjustment is less than the Estimated Tax Adjustment, Bidco shall pay the difference to Atlanta. Any such amount owing by Green Bay or Bidco to Atlanta shall be paid by Green Bay within five Business Days of the delivery of the Tax Adjustment statement.

ARTICLE 7

COVENANTS

7.1 Regulatory Covenants

(a) Purchaser will use commercially reasonable efforts to obtain Competition Act Compliance or cause Competition Act Compliance to be obtained and in doing so will cooperate and consult with Vendor. Without limiting the generality of the foregoing, Purchaser will as soon as practicable, and in any event within five (5) Business Days after the date of this Agreement, prepare and provide submissions to the Commissioner of Competition including an application for an Advance Ruling Certificate, and will promptly furnish any additional information requested under the Competition Act. In addition, unless Purchaser determines that such notifications need not be filed, Purchaser will prepare and file the requisite notifications on behalf of Purchaser and CFL pursuant to Part IX of the Competition Act as soon as practical.

(b) Purchaser will use commercially reasonable efforts to obtain Investment Canada Act Approval. Purchaser shall submit an application for review in connection therewith as soon as practicable, and in any event within five (5) Business Days after the date of this Agreement.

(c) Purchaser will keep Vendor reasonably informed of the status of the review process for obtaining Competition Act Compliance and Investment Canada Act Approval, will provide Vendor with copies of any submission or application in draft form (with any confidential information redacted therefrom, with a complete copy to Vendor’s external counsel), will incorporate Vendor’s reasonable comments in any such submission and will allow Vendor’s external counsel to participate in any substantive meetings or communications with the relevant Government Authority to the extent permitted by the relevant Government Authority, at all times providing reasonable notice thereof.

(d) Nothing in this Section 7.1 shall oblige Purchaser to disclose to Vendor any written communications or information which Purchaser, acting reasonably, considers to be confidential and sensitive in nature, provided that arrangements will be made among the Parties and their counsel as necessary for any such confidential written communications or information to be exchanged on an “external counsel only” basis.

10

(e) Notwithstanding anything to the contrary in this Agreement, in no event shall Purchaser be obligated to make proposals, agree or carry out agreements or submit to orders providing for (i) the sale, license or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets of Purchaser, any of its Affiliates or CFL, (ii) the imposition of any limitation or regulation on the ability of Purchaser, any of its Affiliates or CFL to freely conduct their business or own such assets, or (iii) the holding separate of the Purchased Interest or any limitation or regulation on the ability of Purchaser or any of its Affiliates to exercise full rights of ownership of the Purchased Interest.

Purchaser acknowledges that Viterra is currently working towards finalizing the Arrangement, including a pre-acquisition reorganization, which shall be prioritized by Viterra ahead of assisting Purchaser with the filings contemplated by this Section 7.2 and that Viterra is and will be assisting other purchasers of its assets so its available resources to assist Purchaser will be limited by these commitments; provided that Vendor agrees to cooperate with Purchaser in good faith to address any material delays resulting from the foregoing and Vendor further agrees to use commercially reasonable efforts to cause Viterra to promptly comply with any request from any Governmental Authority.

(b) Subject to obtaining an irrevocable and complete release and discharge from all claims and potential claims in respect of the period prior to the Closing Date from the Purchaser in favour of each of Viterra’s director nominees to the board of directors of CFL, Vendor shall cause each of Viterra’s director nominees to the board of directors of CFL to resign or be removed as a CFL director effective as of the Closing Time.

(▇) At any time prior to the Closing, this Agreement may be terminated and the Intended Transaction abandoned by authorized action taken by the terminating Party:

(i) by written consent of the Parties;

(ii) by any Party, if the conditions set forth in Section 9.3(c) or 9.3(d) are not satisfied by the applicable date or dates set forth therein (as such dates may be extended in accordance with such sections) where the failure to satisfy any such condition is not the result, directly or indirectly, of a breach of this Agreement by the Party seeking to terminate the Agreement;

(iv) by any Party, if the Arrangement Agreement is terminated or abandoned; or

(v) by Purchaser if the Closing shall not have occurred prior to the first anniversary of the date of this Agreement (where the failure to close is not the result, directly or indirectly, of a breach of this Agreement by Purchaser).

(b) Upon the termination of this Agreement in accordance with the terms contained herein, this Agreement shall be of no further force or effect; provided, however, that: (i) this Article 10, Section 1.5, Section 2.4, Section 2.9, the provisos in

ARTICLE 11

INDEMNIFICATION

11.1 Indemnification by Vendor

Subject to Section 11.3, from and after the Closing, Vendor agrees to indemnify and save harmless the Purchaser Indemnified Parties from all Losses suffered or incurred by any of them as a result of or arising out of or in connection with:

(a) any breach by Vendor or any inaccuracy of any representation or warranty of Vendor contained in this Agreement; and

(b) any breach or non-performance by Vendor of any covenant to be performed by Vendor which is contained in this Agreement.

11.2 Indemnification by Purchaser

Subject to Section 11.3, from and after the Closing, Purchaser agrees to indemnify and save harmless the Vendor Indemnified Parties from all Losses suffered or incurred by any of them as a result of or arising out of or in connection with:

(a) any breach by Purchaser or any inaccuracy of any representation or warranty of Purchaser contained in this Agreement;

15

(b) any breach or non-performance by Purchaser of any covenant to be performed by Purchaser which is contained in this Agreement; and

(c) the Assumed Liabilities.

11.3 Limitations on Claims

The aggregate Liability of any Party hereunder with respect to Losses arising from or arising out of matters relating to this Agreement shall not exceed an amount equal to the Purchase Price.

11.4 Notice of Claim

If a Party (the “Indemnified Party”) shall become aware of any Claim in respect of which the other Party (the “Indemnifying Party”) agreed to indemnify the Indemnified Party pursuant to this Agreement, the Indemnified Party shall promptly give written notice thereof (a “Notice of Claim”) to the Indemnifying Party. Such notice shall specify whether the Claim arises as a result of a Claim by a Third Party against the Indemnified Party (a “Third Party Claim”) or whether the Claim does not so arise (a “Direct Claim”), and shall also specify with reasonable particularity (to the extent that the information is available) the factual basis for the Claim and the amount of the Claim, if known. If the Indemnified Party fails to give such notice, such failure shall not preclude the Indemnified Party from obtaining such indemnification, but its right to indemnification may be reduced to the extent such delay prejudices the defense of such Claim, increases the amount of the liability or cost of defense, or prejudices Indemnifying Party’s ability to recover any sums under applicable insurance coverage.

11.5 Direct Claims

With respect to any Direct Claim, following receipt of notice from the Indemnified Party of the Claim, the Indemnifying Party shall have sixty (60) days to make such investigation of the Claim as is considered necessary or desirable. For the purpose of such investigation, the Indemnified Party shall make available to the Indemnifying Party the information relied upon by the Indemnified Party to substantiate the Claim, together with all such other information as the Indemnifying Party may reasonably request. If both Parties agree at or prior to the expiration of such sixty (60) day period (or any mutually agreed upon extension thereof) to the validity and amount of such Claim, the Indemnifying Party shall immediately pay to the Indemnified Party the full agreed upon amount of the Claim, failing which the matter shall be submitted to arbitration pursuant to Article 13.

11.6 Third Party Claims

With respect to any Third Party Claim, the Indemnifying Party shall have the right by notice to the Indemnified Party not later than 30 days after receipt of the notice described in Section 11.4, at its expense, to participate in or assume control of the negotiation, settlement or defence of the Claim:

(a) If the Indemnifying Party elects to assume control, the Indemnifying Party shall reimburse the Indemnified Party for all the Indemnified Party’s reasonable out of pocket expenses (including reasonable legal fees) as a result of such participation or assumption as such expenses are incurred. If the Indemnifying

16

Party elects to assume such control, the Indemnified Party shall continue to have the right to participate in the negotiation, settlement or defence of such Third Party Claim and to retain counsel to act on its behalf, provided that the fees and disbursements of such counsel shall be paid by the Indemnified Party unless (i) the Indemnifying Party consents to the retention of such counsel at its expense or (ii) the named parties to any action or proceeding include both the Indemnifying Party and the Indemnified Party and the representation of both the Indemnifying Party and the Indemnified Party by the same counsel would be inappropriate due to the actual or potential differing interests between them (such as the availability of different defences) in which case the fees and disbursements of such counsel shall be paid by the Indemnifying Party; and

(b) If the Indemnifying Party assumes the defence of any Third Party Claim, the Indemnified Party shall not settle such Third Party Claim unless the Indemnifying Party consents in writing (such consent not to be unreasonably withheld or delayed). If the Indemnifying Party assumes the defence of any Third Party Claim, the Indemnifying Party shall not, without the prior written consent of the Indemnified Party (which may be withheld in the Indemnified Party’s sole discretion), enter into any settlement or compromise or consent to the entry of any judgment with respect to such Third Party Claim if such settlement, compromise or judgment (x) involves a finding or admission of wrongdoing by the Indemnified Party or any of its Affiliates, (y) does not include an unconditional written release by the claimant or plaintiff of the Indemnified Party and its Affiliates from all liability in respect of such Third Party Claim or (z) imposes equitable remedies or any obligation on the Indemnified Party or any of its Affiliates other than solely the payment of money damages for which the Indemnified Party will be indemnified hereunder. If the Indemnified Party assumes the defence of any Third Party Claim, the Indemnified Party shall not settle such Third Party Claim without the prior written consent of the Indemnifying Party (such consent not to be unreasonably withheld or delayed).

11.7 Cooperation

The Indemnified Party and the Indemnifying Party shall cooperate fully with each other with respect to Third Party Claims, and shall keep each other fully advised with respect thereto (including supplying copies of all relevant documentation promptly as it becomes available).

11.8 Remedies

The Parties acknowledge and agree that from and after the Closing, except in the case of fraud or intentional misrepresentation, the indemnification provisions of this Article 11 shall be the sole and exclusive remedy for any Claim for breach of any covenant, representation, warranty or other provision of this Agreement; provided, however, that the provisions contained in this Article 11 shall not limit or otherwise apply in any way to any Claim for specific performance, or any other similar remedy, or injunctive relief, or any other similar remedy.

11.9 Mitigation

Nothing contained in this Article 11 shall eliminate or reduce an Indemnified Party’s obligations to mitigate its Losses.

17

11.10 No Consequential Damages

No Party will be liable for consequential, incidental, aggravated, exemplary or punitive damages pursuant to this Agreement but, for certainty, such exclusion does not include Losses resulting from diminution in value or loss of profit (including for future earnings to be derived from the Purchased Interest attributable to any Direct Claim).

11.11 Indemnity Payment

If any payment made by any Party pursuant to this Article 11 is deemed by the Excise Tax Act (Canada) to include harmonized sales tax, GST or is deemed by any applicable provincial or territorial legislation to include a similar value added or multi-staged tax, the amount of such payment shall be increased accordingly.

ARTICLE 12

SURVIVAL; TIME LIMITATIONS

12.1 Survival of Representations, Warranties, Covenants and Indemnities

All provisions of this Agreement shall not merge upon Closing, but shall survive the execution, delivery and performance of this Agreement, Closing and the execution and delivery of any transfer documents or other documents of title to the Purchased Interest and all other agreements, certificates and instruments delivered pursuant to this Agreement and the payment of the consideration for the Purchased Interest without limitation as to time unless such provision specifies a term, in which case it shall survive for such specified term.

ARTICLE 13

DISPUTE RESOLUTION

13.1 Agreement to Arbitrate

The receiving Party shall respond promptly in writing with the name of one of its senior officers empowered to engage in negotiations to resolve the Dispute. The senior officers shall meet promptly thereafter. If, for any reason, the Dispute has not been resolved within twenty (20) Business Days of receipt by a Party of Notice, either Party may proceed to arbitration pursuant to this Article 13(b). The sending of Notice pursuant to this Section 13.1(a) shall toll any statute of limitations applicable to any Dispute until ten (10) days after the expiration of the twenty (20) Business day period set forth above.

(b) Any Dispute that has not been timely resolved in accordance with Section 13.1(a), shall on the request of any Party be resolved by final and binding arbitration proceedings to be conducted before a panel of three arbitrators in accordance with the Rules of Arbitration of the International Chamber of Commerce (“ICC”) Court of Arbitration then in effect (the “Rules”) except as

18

modified herein. Any order or judgment by the arbitral tribunal may be enforced by any court having jurisdiction over any of the Parties or any of their assets.

(c) The arbitration shall be seated at ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇, conducted in English, and its procedures shall be governed by the Ontario International Arbitration Act and the United Nations Convention on the Recognition and Enforcement of Foreign Arbitral Awards.

(d) Each Party shall nominate an arbitrator in accordance with the Rules. If the arbitrators so nominated cannot agree on the third arbitrator within fifteen (15) Business Days after the confirmation by the ICC Court of Arbitration (“ICC Court”) of the appointment of the second arbitrator, either Party may request that the ICC Court appoint the third arbitrator, who shall serve as chair of the arbitral tribunal. No arbitrator shall have been a director, officer or employee of, or contractor or service provider to, or director, officer, beneficial owner or close relative of a beneficial owner of any contractor or service provider to, any Party during a period of 5 years preceding his or her appointment as an arbitrator.

(e) The Party that, in the opinion of the arbitrators, does not prevail in any arbitration shall pay the costs of the arbitration (including reasonable attorneys’ fees and expenses and the fees expenses of the arbitral tribunal and the ICC) of the Party which prevails, unless otherwise awarded by the arbitrators.

(f) The arbitral tribunal shall deliver its final award on the merits within thirty (30) Business Days after close of the hearing on the merits.

(g) Except for decisions relating to discovery, which may, at the discretion of the arbitral tribunal, be made by the chair alone, no decision of the arbitrators shall be valid unless a quorum of the arbitrators is present at a meeting to consider such decision. A quorum of the arbitrators shall be no less than 3. The arbitrators may meet to consider a decision in person, by telephone or by teleconference and it shall be within their discretion to determine the appropriate method of meeting in respect of any particular decision that is required. Provided that a quorum of arbitrators is present, any majority in number of the arbitral tribunal shall have the power to make any findings of fact, law or mixed fact and law necessary or incidental to the determination of the Dispute, make any ruling or order on procedural or substantive matters arising out of or related to the Dispute including as to costs, and to grant any remedy or relief that could be granted by a Justice of the Court of Queen’s Bench of Alberta at a trial of the Dispute, including final, interim, interlocutory and partial awards covering damages and/or temporary or permanent injunctive relief.

(h) All matters relating to any Dispute which is the subject matter of arbitration hereunder, including all submissions made to the arbitrators and the decision of the arbitrators, shall be treated as confidential by the Parties and the Parties shall, and shall cause any witnesses, counsel or professional advisers retained in connection with such an arbitration, to maintain all such matters in strict

19

confidence, except as may be required by law or regulatory authority or as may be required to enforce any award rendered by the arbitral tribunal.

(i) By agreeing to arbitration, the Parties do not intend to deprive any court of its jurisdiction to issue a pre-arbitral injunction, pre-arbitral attachment or other order in aid of arbitration proceedings and the enforcement of any award. Without prejudice to such provisional remedies as may be available under the jurisdiction of a national court, the arbitral tribunal shall have full authority to grant provisional remedies or order the Parties to request that a court modify or vacate any temporary or preliminary relief issued by a such court, and to award damages for the failure of any Party to respect the arbitral tribunal’s orders to that effect. The Parties hereby submit to the exclusive jurisdiction of the courts of applicable jurisdiction in Toronto Ontario for any action or proceeding to compel arbitration and for provisional relief in aid of arbitration, and to the non-exclusive jurisdiction of such courts for entry and enforcement of any arbitral award. Each Party unconditionally and irrevocably waives any objections which they may have now or in the future to the jurisdiction of such courts, including without limitation objections by reason of lack of personal jurisdiction, improper venue, or inconvenient forum.

13.2 Certain Specific Waivers; Equitable Relief

Each of the Parties irrevocably and unconditionally waives any rights and defences it may have to resist an application for specific performance, or any other similar remedy, requiring it to perform its covenants under this Agreement (including its covenant to complete Closing or pay the Purchase Price at Closing or, (a) in the case of Vendor, its covenant to make those deliveries required by Section 3.3 and (b) in the case of Purchaser, its covenant to make those deliveries required by Section 3.4) and any rights it may have to commence an application for an injunction, or any other similar remedy, to prevent or delay Closing (or any part of it) from occurring. Without limitation to the foregoing, the Parties agree that monetary damages would not alone be sufficient to remedy any breach by a Party of its covenant to complete Closing and that each Party will be entitled to equitable relief, including by injunction and specific performance, in the event of any breach by the other Party of its covenant to complete Closing, in addition to any other remedy available pursuant to this Agreement or by Applicable Law. The Parties further waive any requirement for the deposit of security or posting of any bond in connection with the application for or granting of any equitable remedy.

The Escrow Agent may resign as escrow agent at any time, by giving at least thirty (30) Business Days’ prior written notice of such resignation to Glencore and the Purchaser. Such removal or resignation shall take effect upon the appointment of a successor escrow agent as provided below in this Section 4.2. In either event, Glencore and the Purchaser will jointly and promptly select a successor escrow agent, and Glencore and the Purchaser will enter into an agreement with such successor escrow agent in substantially the form of this Escrow Agreement. The removal or resignation of the Escrow Agent shall relieve the Escrow Agent of any responsibility or duty thereafter arising hereunder, but shall not relieve the Escrow Agent of responsibility to account to Glencore and the Purchaser for funds received by the Escrow Agent prior to the effective date of such removal or resignation. If a substitute for the Escrow Agent hereunder shall not have been selected prior to the expiration of sixty (60) days following the date of the notice of removal or resignation, the Escrow Agent shall be entitled to petition any court of competent jurisdiction for the appointment of a substitute for it hereunder or, in the alternative, it may (i) transfer and deliver the funds deposited in the escrow account to or upon the order of such court or (ii) keep safely all funds in the escrow account until it receives joint notice from Glencore and the Purchaser of a substitute appointment. The Escrow Agent shall be discharged from all further duties hereunder upon acceptance by the substitute escrow agent of the Escrow Agent’s duties hereunder or upon transfer and delivery of the funds in the escrow account to or upon the order of any court.

Section 4.3 Indemnification of the Escrow Agent. Glencore and the Purchaser agree to jointly and severally hold the Escrow Agent harmless from and to indemnify the Escrow Agent against, any loss, liability, claim or demand arising out of or in connection with the performance of its obligations in accordance with the provisions of this Escrow Agreement, except to the extent such loss, liability, claim or demand is finally adjudicated to have been primarily caused by the bad faith, gross negligence or willful misconduct of the Escrow Agent. The provisions of this Section 4.3 shall survive the termination of this Escrow Agreement or the resignation or removal of the Escrow Agent.

Section 4.4 Fees. The Escrow Agent’s annual fees are set forth on Exhibit C. The Escrow Agent’s annual fee shall be payable upon execution of this Escrow Agreement and thereafter on each anniversary date of this Escrow Agreement. All such annual fees payable to the Escrow Agent hereunder shall be paid 50% by Glencore and 50% by the Purchaser. The Escrow Agent shall be entitled to receive all reasonable, out-of-pocket expenses, disbursements and advances incurred or made by the Escrow Agent in connection with this Escrow Agreement. All such expenses, disbursements and advances payable to the Escrow Agent hereunder shall be paid to the Escrow Agent 50% by Glencore and 50% by the Purchaser. The Escrow Agent shall

5

provide Glencore and the Purchaser with prompt written notice of all payments made to the Escrow Agent from the Escrow Fund pursuant to this Section 4.4. The Escrow Agent shall have, and is hereby granted, a prior lien upon the Escrow Fund with respect to its unpaid fees, non-reimbursed expenses and unsatisfied indemnification rights, superior to the interests of any other persons or entities and is hereby granted the right to set off and deduct any unpaid fees, non-reimbursed expenses and unsatisfied indemnification rights from the Escrow Fund.

Section 4.5 Merger or Consolidation. Any corporation or association into which the Escrow Agent may be converted or merged, or with which it may be consolidated, or to which it may sell or transfer all or substantially all of its corporate trust business and assets as a whole or substantially as a whole, or any corporation or association resulting from any such conversion, sale, merger, consolidation or transfer to which the Escrow Agent is a party, shall be and become the successor escrow agent under this Escrow Agreement and shall have and succeed to the rights, powers, duties, immunities and privileges as its predecessor, without the execution or filing of any instrument or paper or the performance of any further act.

Section 4.6 Attachment of Escrow Funds; Compliance with Legal Orders. In the event that any Escrow Funds shall be attached, garnished or levied upon by any court order, or the delivery thereof shall be stayed or enjoined by an order of a court, or any order, judgment or decree shall be made or entered by any court order affecting the Escrow Funds, the Escrow Agent is hereby expressly authorized, in its sole discretion, to respond as it deems appropriate or to comply with all writs, orders or decrees so entered or issued, or which it is advised by legal counsel of its own choosing is binding upon it, whether with or without jurisdiction. In the event that the Escrow Agent obeys or complies with any such writ, order or decree it shall not be liable to any parties hereto or to any other person, firm or corporation, should, by reason of such compliance notwithstanding, such writ, order or decree be subsequently reversed, modified, annulled, set aside or vacated.

Section 5.2 Severability. If any term or other provision of this Escrow Agreement is invalid, illegal or incapable of being enforced by any Applicable Law, all other terms and provisions of this Escrow Agreement shall nevertheless remain in full force and effect for so long as the economic and legal substance of the transactions contemplated by this Escrow Agreement are not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Escrow Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated by this Escrow Agreement are consummated as originally contemplated to the greatest extent possible.

Section 5.3 Amendment. This Escrow Agreement may not be amended or modified except (a) by an instrument in writing signed by, or on behalf of, all the parties hereto or (b) by a waiver in accordance with Section 5.4.

Section 5.4 Waiver. Any party to this Escrow Agreement may (a) extend the time for the performance of any of the obligations or other acts of another party, (b) waive any inaccuracies in the representations and warranties of another party contained herein or in any document delivered by another party pursuant hereto or (c) waive compliance with any of the agreements of another party or conditions to such party’s obligations contained herein. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party to be bound thereby. Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Escrow Agreement. The failure of any party hereto to assert any of its rights hereunder shall not constitute a waiver of any of such rights. All rights and remedies existing under this Escrow Agreement are cumulative to, and not exclusive of, any rights or remedies otherwise available.

Section 5.5 Counterparts. This Escrow Agreement may be executed and delivered (including by facsimile or electronic transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original, but all of which taken together shall constitute one and the same agreement.

Section 5.6 Headings. The subject headings of Articles and Sections of this Escrow Agreement are included for purposes of convenience only and shall not affect the construction or interpretation of any of its provisions.

Section 5.7 Assignment. Neither this Escrow Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of law or otherwise) without the prior written consent of the other parties. Subject to

8

the preceding sentence, this Escrow Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective permitted successors and assigns.

Section 5.8 Entire Agreement. This Agreement and the Purchase Agreement (including, for certainty, all documents being delivered or to be delivered by the parties thereto or entered in connection herewith) constitute the entire agreement of the parties hereto with respect to the subject matter hereof and thereof and supersede all prior agreements and undertakings, both written and oral, between Glencore and the Purchaser with respect to the subject matter hereof and thereof.

Section 5.9 Interpretation. The parties have participated jointly in the negotiation and drafting of this Escrow Agreement. In the event an ambiguity or question of intent or interpretation arises, this Escrow Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Escrow Agreement.

Section 5.10 Jurisdiction. This Escrow Agreement shall be governed by and construed, interpreted and enforced in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein, excluding any rule or principle of conflicts of law that may provide otherwise. The parties hereby irrevocably (a) attorn to the non-exclusive jurisdiction of the courts of the Province of Ontario with respect to any matter arising under or related to this Escrow Agreement, (b) waive any objection to such jurisdiction on the grounds of venue or forum non conveniens, the absence of any person or subject matter jurisdiction and any similar grounds, (c) consent to service of process by mail (in accordance with Section 5.1 or any other manner permitted by law) and (d) agree to be bound by any judgment rendered thereby in connection with this Escrow Agreement. The foregoing consents to jurisdiction by the parties shall not be deemed to confer rights on any person other than the parties.

Section 5.11 Termination of this Escrow Agreement. This Escrow Agreement shall terminate on the date on which the entire Escrow Fund has been distributed or upon the written agreement of Glencore and the Purchaser. In the event that the Escrow Agreement terminates prior to the distribution of all of the entire Escrow Fund, Glencore and the Purchaser, jointly, shall deliver written instructions, signed by both Glencore and the Purchaser, to the Escrow Agent regarding the disposition of any remaining amounts in the Escrow Funds.

ASSIGNMENT AND ASSUMPTION AGREEMENT

This Assignment and Assumption Agreement (this “Assignment”), dated as [·], 2012, is made by and between Viterra Inc., a corporation existing under the laws of Canada

(“Viterra”), and [·], a corporation existing under the laws of Delaware (“CF Affiliate” and, together with Viterra, the “Parties”, and each, individually, a “Party”). Capitalized terms used but not defined herein have the meanings ascribed to such terms in the Purchase and Sale Agreement (as defined below).

WHEREAS, Glencore International plc, a corporation existing under the laws of Jersey (“Glencore”), and CF Industries Holdings, Inc., a corporation existing under the laws of Delaware, are parties to that certain Purchase and Sale Agreement, dated as of [·], 2012 (as amended from time to time according to its terms, the “Purchase and Sale Agreement”); and

WHEREAS, pursuant to the Purchase and Sale Agreement and for the consideration described therein, Glencore has agreed to cause Viterra to assign, transfer, deliver and convey to CF Affiliate the Member Nitrogen Agreement and all of Viterra’s right, title, and interest in and to the Member Nitrogen Agreement, and CF Affiliate has agreed to assume, pay, perform and discharge as they become due the Assumed Liabilities.

NOW, THEREFORE, in consideration of the foregoing premises and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the Parties hereby agree as follows:

1. Upon the terms and subject to the conditions set forth in the Purchase and Sale Agreement, Viterra hereby assigns, transfers, delivers and conveys to CF Affiliate all of its right, title, and interest in and to the Member Nitrogen Agreement.

2. Upon the terms and subject to the conditions set forth in the Purchase and Sale Agreement, CF Affiliate hereby assumes and agrees to pay, perform and discharge as they become due the Assumed Liabilities. For greater clarity, CF Affiliate does not assume any liability or obligation of Viterra other than the Assumed Liabilities.

3. The validity, interpretation and effect of this Assignment shall be construed, performed and enforced in accordance with, and governed by, the Province of Alberta and the federal laws of Canada applicable in that province.

4. This Assignment shall bind and shall enure to the benefit of the respective Parties hereto and to their respective successors and permitted assigns. Nothing in this Assignment, express or implied, is intended or shall be construed to confer upon, or give to, any Person other than the Parties and their respective permitted successors and assigns, any remedy or claim under or by reason of this Assignment or any terms, covenants or condition hereof, and all the terms, covenants and conditions, promises and agreements contained in this Assignment shall be for the sole and exclusive benefit of the Parties and their respective permitted successors and assigns.

5. Nothing in this Assignment shall be construed to be a modification of, or limitation on, any provision of the Purchase and Sale Agreement. If there is any inconsistency between the terms of this Assignment and those in the Purchase and Sale Agreement, the terms of the

Purchase and Sale Agreement will prevail. The Parties shall take any necessary steps to conform the inconsistent provisions to the terms of the Purchase and Sale Agreement.

6. This Assignment may be executed in one or more counterparts, which may be delivered by facsimile transmission or electronically scanned form, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

7. If any provision of this Assignment is invalid, illegal or incapable of being enforced by any role of law or public policy, all other provisions of this Assignment shall nevertheless remain in full force and effect.
