MEMBERSHIP INTEREST PURCHASE AGREEMENT

MEMBERSHIP INTEREST PURCHASE AGREEMENT (this “Agreement”), dated as of October 31, 2012, between Rentech Nitrogen Partners, L.P., a Delaware limited partnership (“Buyer”), and Agrifos Holdings Inc., a Delaware corporation (“Seller”).

SUMMARY OF TRANSACTION

Seller owns all of the issued and outstanding limited liability company membership interests of Agrifos LLC (collectively, the “Interests”), a Delaware limited liability company (the “Company”). Buyer desires to purchase, and Seller desires to sell, all of the Interests upon the terms and subject to the satisfaction of the conditions set forth in this Agreement.

For U.S. federal and state income tax purposes, the parties intend to treat all consideration paid hereunder to Seller, including the Common Units and the Supplemental Unit, as received from Buyer in exchange for the assets of the Company Group in a transaction that is (a) part sale of such assets and (b) part contribution of such assets in exchange for the Common Units and the Supplemental Unit received in a non-taxable exchange pursuant to Section 721 of the Code at the Closing, even though the value of the Common Units to be delivered in substitution for the Supplemental Unit may not be finally determined until the occurrence of certain conditions and events after the Closing.

To effect such transactions and in consideration of the mutual covenants, representations, warranties and agreements hereinafter set forth, and intending to be legally bound hereby, the parties hereto agree as follows:

ARTICLE I

SALE OF INTERESTS AND TERMS OF PAYMENT

Section 1.01 Sale of the Interests. Upon the terms and subject to the satisfaction of the conditions contained in this Agreement, at the Closing Seller will sell, assign, transfer and deliver to Buyer, and Buyer will purchase and acquire from Seller, the Interests free and clear of all Encumbrances.

Section 1.02 Consideration. Upon the terms and subject to the satisfaction of the conditions contained in this Agreement, in consideration of the aforesaid sale, assignment, transfer and delivery of the Interests, Buyer will pay or cause to be paid: (a) the Initial Purchase Price to be paid at the Closing, plus the Post-Closing Addition or minus the Post-Closing Reduction to be paid after the Closing in an amount determined pursuant to Section 1.06; and (b) the Supplemental Purchase Price which shall be initially satisfied through the delivery of the Supplemental Unit at the Closing, and which shall be subject to the satisfaction of the performance conditions set forth in and subject to the adjustments in the manner contemplated by Section 1.08 (collectively, the “Purchase Price”). The “Initial Purchase Price” shall be an initial amount equal to the aggregate of the Initial Cash Purchase Price and the Initial Equity Purchase Price. The “Initial Cash Purchase Price” shall be an initial amount equal to (i) One Hundred Thirty Seven Million Nine Hundred Twenty Thousand Dollars ($137.92 million), less (ii) the amount of the Closing Reduction, if any, plus (iii) the amount of the Estimated Cash and Cash Equivalents, plus (iv) the amount of the Closing Addition, if any. The “Initial Equity Purchase

Price” shall be a number of Common Units equal to (A) Twenty Million Dollars ($20 million) divided by (B) the VWAP on the date hereof (such number of Common Units to be rounded up or down to the nearest whole Common Unit, with any 5 in the first decimal place being rounded up).

(the “Escrow Agent”), (i) Two Million Five Hundred Thousand Dollars ($2.5 million) in immediately available funds (the “Price Adjustment Escrow Amount”), (ii) a number of Common Units arrived at by dividing Six Million Dollars ($6 million) by the VWAP on the date hereof (such number of Common Units to be rounded up or down to the nearest whole Common Unit, with any 5 in the first decimal place being rounded up) (the “General Indemnity Escrow Amount”), (iii) the sum of (A) Four Million Dollars ($4 million) in immediately available funds (the “Initial Additional Indemnity Cash Amount”) and (B) a number of Common Units arrived at by dividing Six Million Dollars ($6 million) by the VWAP on the date hereof (such number of Common Units to be rounded up or down to the nearest whole Common Unit, with any 5 in the first decimal place being rounded up) (collectively, with the Initial Additional Indemnity Cash Amount, the “Additional Indemnity Escrow Amount”) and (iv) Seven Hundred Fifty Thousand Dollars ($750,000) in immediately available funds (the “Sales and Use Tax Indemnity Escrow Amount”), by wire transfer of such immediately available funds and delivery of such Common Units in book-entry form to the

(b) on behalf of the Company Group, to such account or accounts as designated by (i) if a Payoff Letter has been executed in respect of such Company Debt, the applicable lender or agent in each Payoff Letter, an amount in immediately available funds equal to that portion of the Payoff Amount for the Company Debt to which such Payoff Letter relates and (ii) if no Payoff Letter has been executed in respect of such Company Debt, the applicable creditor or counterparty, an amount equal to that portion of the Payoff Amount for such Company Debt as set forth in the Loan Pay-Off Statement;

(c) on behalf of the Company Group, to the account or accounts as Seller specifies to Buyer in the Estimated Transaction Expense Statement, the aggregate amount of the Estimated Transaction Expenses;

(d) on behalf of the Operating Subsidiary, to Buyer, the aggregate amount of the Estimated Pension and Retiree Liability, which Buyer shall retain for the account of the Operating Subsidiary;

(e) on behalf of the Company Group, to the account or accounts as specified by Buyer, an amount equal to the sum of (i) the Closing Date Bonus Payment which shall be paid in accordance with Section 8.06 and (ii) Closing Date Bonus FICA (the payments made under Sections 1.04(b) through (e) being referred to herein as the “Company Group Closing Payment”); and

Section 1.05 Characterization of Payments. The payments made pursuant to Sections 1.04(a) and 1.04(f) shall be considered payments from Buyer to Seller. The Company Group Closing Payment, as adjusted hereunder, shall be considered payments on behalf of the Company Group and in respect of obligations and liabilities of the Company Group.

Section 1.06 Adjustment of Initial Purchase Price.

(a) Adjustment at Closing. In accordance with Section 1.03, Seller shall deliver to Buyer the Estimated Closing Balance Sheet and a good faith calculation of the Estimated Net Working Capital based upon the Estimated Closing Balance Sheet, the Estimated Closing Date Indebtedness, the Estimated Transaction Expenses and the Estimated Cash and Cash Equivalents, together with reasonable supporting calculations and supporting documentation therefor. The Estimated Closing Balance Sheet shall be prepared in accordance with GAAP consistently applied using the Company Accounting Principles; provided, however, that in the event of a conflict between consistency with the Company Accounting Principles and compliance with GAAP, except for the Company Accounting Principles set forth in Schedule

1.06(a), compliance with GAAP shall control. Seller will consider in good faith any revisions to the calculations set forth in the Estimated Closing Balance Sheet proposed by Buyer and the Estimated Closing Balance Sheet shall be modified accordingly to reflect any revisions agreed upon by Buyer and Seller. At the Closing, as provided in Section 1.02, the Initial Cash Purchase Price shall be determined in part by (i) reducing it by the amount, if any, by which the Base-Line Net Working Capital exceeds the Estimated Net Working Capital, or (ii) increasing it by the amount, if any, by which the Estimated Net Working Capital exceeds the Base-Line Net Working Capital. The reduction in and addition to the Initial Cash Purchase Price referred to in the preceding sentence are hereafter collectively referred to as the “Closing Reduction” and “Closing Addition,” respectively. In addition, as provided in Sections 1.04(b) through (e), a portion of the Initial Cash Purchase Price shall be used to make the Company Group Closing Payment.

(b) Final Closing Balance Sheet. No later than one hundred twenty (120) days after the Closing Date, Buyer will deliver to Seller the final Closing Balance Sheet (the “Final Closing Balance Sheet”) and the calculations of the Final Net Working Capital based upon the Final Closing Balance Sheet, as well as the Final Closing Date Indebtedness, the Final Transaction Expenses, the Final Cash and Cash Equivalents and the Final Pension and Retiree Liability. The Final Closing Balance Sheet shall be prepared in accordance with GAAP consistently applied using the Company Accounting Principles; provided, however, that all accounts receivable amounts will reflect the most recent information available regarding the value of receivables subject to any provisional pricing arrangements; and provided, further, that in the event of a conflict between consistency with the Company Accounting Principles and compliance with GAAP, except for the Company Accounting Principles set forth on Schedule 1.06(a), compliance with GAAP shall control. The Final Closing Balance Sheet shall be accompanied by a statement (the “Final Sales Statement”) of each Final Sale of ammonium sulfate that was a Provisional Sale as of immediately prior to the Closing, including the tonnage and Final Sales Price thereof. Additionally, Seller shall direct Buck Consultants, LLC and PricewaterhouseCoopers LLP to prepare the calculation of the Final Pension and Retiree Liability as of the Closing Date by Buck Consultants, LLC updating the Pension Reports for the Pension Underfunding and PricewaterhouseCoopers LLP updating the Actuarial Valuation for the Retiree Obligation, in each case, as of the Closing Date using the same methodology as was used to prepare the Pension Reports and Actuarial Valuation. Seller shall direct such firms to deliver such calculation to Buyer and Seller no later than one hundred twenty (120) days after the Closing Date. The Final Pension and Retiree Liability, as determined by Buck Consultants, LLC and PricewaterhouseCoopers LLP, shall be final, conclusive and binding on the parties, absent manifest error. The cost of such updates prepared by Buck Consultants, LLC and PricewaterhouseCoopers LLP shall be paid by Seller.

(i) Following receipt of the Final Closing Balance Sheet, Seller will be afforded a period of sixty (60) days to review the Final Closing Balance Sheet and the Final Sales Statement and the calculations of the Final Net Working Capital, the Final Closing Date Indebtedness, the Final Transaction Expenses and the Final Cash and Cash Equivalents during which period Seller and its advisors shall have the right to inspect the work papers generated by Buyer in preparation of the Final Closing Balance Sheet and the Final Sales Statement and such

calculations and shall have reasonable access, during normal business hours, to the Company Group’s relevant personnel and to information, books and records of the Company Group reasonably requested by Seller and relevant to the Final Closing Balance Sheet, the Final Sales Statement and such calculations. At or before the end of such 60-day review period, Seller will either (A) accept the Final Closing Balance Sheet and the Final Sales Statement in their entirety, in which case Buyer’s calculations shall be final, conclusive and binding on the parties, or (B) deliver to Buyer written notice and a written explanation of those items in the Final Closing Balance Sheet or Final Sales Statement which Seller disputes and the proposed modification of such calculations, in which case only the items identified shall be deemed to be in dispute and the other items shall be deemed to be accepted; provided, however, that the only bases for objection with respect to the Final Net Working Capital calculation shall be (1) non-compliance with GAAP, the Company Accounting Principles or the provision regarding accounts receivable amounts in Section 1.06(b), as applicable and (2) computational errors. Seller shall be deemed to have accepted the Final Closing Balance Sheet and the Final Sales Statement in their entirety, and to have agreed with all items and amounts contained in the Final Closing Balance Sheet, the Final Sales Statement and Buyer’s calculations of the Final Net Working Capital, the Final Closing Date Indebtedness, the Final Transaction Expenses and the Final Cash and Cash Equivalents if it fails to deliver such notice and explanation of any items it disputes at or before the end of such 60-day review period. Within a further period of twenty (20) days from the end of the aforementioned review period, the parties and their accountants will attempt to resolve in good faith any disputed items.

(ii) Failing such resolution, either Seller or Buyer may refer the unresolved disputed items for final binding resolution to the Dispute Accountants to review this Agreement and the disputed items or amounts for the purpose of calculating the Final Net Working Capital, the Final Closing Date Indebtedness, the Final Transaction Expenses and/or the Final Cash and Cash Equivalents. In making such calculations, the Dispute Accountants shall consider only those items or amounts in the Final Closing Balance Sheet, the Final Sales Statement or the calculations of the Final Net Working Capital, the Final Closing Date Indebtedness, the Final Transaction Expenses and/or the Final Cash and Cash Equivalents as to which Buyer and Seller have disagreed and shall be instructed that it may not resolve any amounts in dispute such that the resolution is greater than the greatest amount proposed by the parties or less than the least amount proposed by the parties. The Dispute Accountants shall deliver to Buyer and Seller, within thirty (30) days of reference of the matter to the Dispute Accountants, a report setting forth its calculations, which shall be prepared in accordance with the standards set forth in Section 1.06(b). The decision of such Dispute Accountants will be nonappealable and incontestable by the parties and will not be subject to collateral attack for any reason. The cost of such review and report shall be paid half by Buyer and half by Seller.

(iii) In the event the Dispute Accountants refuse the engagement under this Section 1.06(c), Buyer and Seller shall mutually agree on another nationally recognized firm of certified public accountants having no material relationship with the Company Group, Buyer or Seller (the “Alternative Dispute Accountant”) to resolve any disputes according to Section 1.06(c). If within thirty (30) days, Buyer and Seller fail to mutually agree on an Alternative Dispute Accountant, Buyer and Seller shall thereafter promptly cause the American Arbitration Association to appoint the Alternative Dispute Accountant, and in making its determination with respect to such appointment, the American Arbitration Association shall take into account, and

attempt to avoid appointing an accounting firm with, any significant preexisting relationship with the Company Group, Buyer or Seller or their respective Affiliates. The fees and expenses of the Alternative Dispute Accountant shall be apportioned in the same manner as described in Section 1.06(c)(ii).

(d) Adjustment after Closing. After the Closing, the Initial Seller Cash Payment shall be (i) (A) reduced by the amount, if any, by which the Final Net Working Capital is less than the Estimated Net Working Capital, or (B) increased by the amount, if any, by which the Final Net Working Capital is greater than the Estimated Net Working Capital, (ii) (A) reduced by the amount, if any, by which the Estimated Cash and Cash Equivalents exceeds the Final Cash and Cash Equivalents, or (B) increased by the amount, if any, by which the Final Cash and Cash Equivalents exceeds the Estimated Cash and Cash Equivalents, (iii) (A) increased by the amount, if any, by which the Estimated Closing Date Indebtedness exceeds the Final Closing Date Indebtedness, or (B) reduced by the amount, if any, by which the Final Closing Date Indebtedness exceeds the Estimated Closing Date Indebtedness, (iv) (A) increased by the amount, if any, by which the Estimated Transaction Expenses exceed the Final Transaction Expenses, or (B) reduced by the amount, if any, by which the Final Transaction Expenses exceed the Estimated Transaction Expenses, and (v) (A) increased by the amount, if any, by which the Estimated Pension and Retiree Liability exceeds the Final Pension and Retiree Liability, or (B) reduced by the amount, if any, by which the Final Pension and Retiree Liability exceeds the Estimated Pension and Retiree Liability. The aggregate net reduction in or addition to the Initial Seller Cash Payment calculated pursuant to this Section 1.06(d) shall be referred to in this Agreement as the “Post-Closing Reduction” (in the case of an aggregate net reduction to the Initial Seller Cash Payment) or as the “Post-Closing Addition” (in the case of an aggregate net addition to the Initial Seller Cash Payment).

(e) Adjustment Payment. After the Final Closing Balance Sheet, the Final Sales Statement and the calculation of the Final Net Working Capital, the Final Closing Date Indebtedness, the Final Transaction Expenses and the Final Cash and Cash Equivalents become final, conclusive and binding upon the parties in accordance with the provisions of Section 1.06(c) and the Final Pension and Retiree Liability becomes final, conclusive and binding upon the parties in accordance with the provisions of Section 1.06(b), then:

(i) If any Post-Closing Addition is required, then Seller shall be entitled to receive a disbursement in accordance with the Escrow Agreement of all Escrow Funds in the Price Adjustment Escrow Account and Buyer will also pay Seller the amount of the Post-Closing Addition in immediately available funds by wire transfer made within ten (10) Business Days after the final determination of the amount of the Post-Closing Addition pursuant to Section 1.06(d).

(ii) If any Post-Closing Reduction is required, then Buyer shall be entitled to receive a disbursement in accordance with the Escrow Agreement from the Price Adjustment Escrow Account in an amount equal to the Post-Closing Reduction and, to the extent sufficient funds are not available therein, Seller will pay to Buyer the amount of such deficiency in immediately available funds by wire transfer made within ten (10) Business Days after the final determination of the amount of the Post-Closing Reduction pursuant to Section 1.06(d) (or, at Buyer’s election, Buyer shall be entitled to receive a disbursement in accordance with the

Escrow Agreement from the General Indemnity Escrow Account or Additional Indemnity Escrow Account in an amount equal to such deficiency); provided, however, that if the amount of the Escrow Funds in the Price Adjustment Escrow Account exceeds the amount of the Post-Closing Reduction, such excess after payment of the Post-Closing Reduction to Buyer shall be disbursed to Seller in accordance with the Escrow Agreement.

Section 1.07 Escrow. On the Closing Date, as provided in Section 1.04(a), Buyer shall deposit with the Escrow Agent the Price Adjustment Escrow Amount into an escrow account (the “Price Adjustment Escrow Account”), the General Indemnity Escrow Amount into an escrow account (the “General Indemnity Escrow Account”), the Additional Indemnity Escrow Amount into an escrow account (the “Additional Indemnity Escrow Account”) and the Sales and Use Tax Indemnity Escrow Amount in an escrow account (the “Sales and Use Tax Indemnity Escrow Account” and, together with the Price Adjustment Escrow Account, the General Indemnity Escrow Account and the Additional Indemnity Escrow Account, the “Escrow Accounts”). The Escrow Agent shall hold each Escrow Account separately from the other Escrow Accounts as provided in the Escrow Agreement. Upon completion of such deposits, Buyer shall have no further obligation to pay such amounts to Seller. The Escrow Funds shall be distributed by the Escrow Agent as provided in the Escrow Agreement. Buyer and Seller shall each pay half of all fees and expenses of the Escrow Agent. Seller shall be considered the owner of Escrow Income that constitutes taxable income for United States federal income and other Tax purposes.

Section 1.08 Supplemental Purchase Price. In addition to the Initial Purchase Price, as may be adjusted pursuant to Section 1.06, the supplemental purchase price (the “Supplemental Purchase Price”), if any, shall be calculated in accordance with this Section 1.08.

(a) Adjusted EBITDA Statement. Buyer shall prepare unaudited financial statements for the Operating Subsidiary attributable to its operations at the Facility for each of the years ending December 31, 2013 and 2014 (the “Financial Statements”) based on the consolidating financial statements Buyer uses to prepare its audited financial statements it files with the SEC, including any relevant audit adjustments therein. The Financial Statements shall be prepared in accordance with GAAP consistently applied using the Company Accounting Principles; provided, however, that (i) in the event of a conflict between consistency with the Company Accounting Principles and compliance with GAAP, except for the Company Accounting Principles set forth in Schedule 1.08(a), compliance with GAAP shall control, (ii) where an accounting or reporting matter may not be determined specifically by GAAP, such as the allocation of certain expenses within the category of “costs of products sold” or “cost of sales”, (A) in the event that the Operating Subsidiary applied a Company Accounting Principle prior to Closing with respect to such accounting or reporting matter, such Company Accounting Principle shall control if such Company Accounting Principle is not inconsistent with GAAP; and (B) in the event that the Operating Subsidiary did not apply a Company Accounting Principle with respect to such accounting or reporting matter, the Buyer Accounting Principles shall control if such Buyer Accounting Principles are not inconsistent with GAAP and (iii) notwithstanding anything to the contrary in this Agreement, any bonus payments to employees of the Operating Subsidiary during the Earn-out Period will be included in Actual SG&A Costs and not within any other category within operating income in the Financial Statements. By April 30, 2015, Buyer shall prepare and deliver to Seller the Financial Statements and a statement of the

cumulative Adjusted EBITDA (the “Adjusted EBITDA Statement”) for the Earn-out Period. An example of the calculation of Adjusted EBITDA is set forth in Exhibit M. The Adjusted EBITDA Statement also shall be accompanied by a calculation of the amount of the Supplemental Purchase Price, if any. Subject to Section 1.08(d), the amount of the Supplemental Purchase Price shall equal the product (which shall not be less than zero) of (1) (I) the cumulative amount of the Adjusted EBITDA for the Earn-out Period, less (II) Fifty Five Million Dollars ($55 million), multiplied by (2) two (2.0); provided, however, that the amount of the Supplemental Purchase Price shall not exceed Fifty Million Dollars ($50 million). As provided in Section 1.08(c), the Supplemental Unit shall entitle Seller to receive the number of Common Units corresponding to the Supplemental Purchase Price, if any.

(b) Dispute Resolution.

(i) Following receipt of the Adjusted EBITDA Statement, Seller will be afforded a period of sixty (60) days to review the Adjusted EBITDA Statement and the calculations of the Adjusted EBITDA, during which period Seller and its advisors shall have the right to inspect the work papers generated by Buyer in preparation of the Adjusted EBITDA Statement and such calculations and have reasonable access, during normal business hours, to the Company Group’s relevant personnel and to information, books and records of the Company Group reasonably requested by Seller and relevant to the Adjusted EBITDA Statement and such calculations. At or before the end of such 60-day review period, Seller will either (A) accept the Adjusted EBITDA Statement in its entirety, in which case Buyer’s calculations shall be final, conclusive and binding on the parties, or (B) deliver to Buyer written notice and a written explanation of those items in the Adjusted EBITDA Statement which Seller disputes and the proposed modification of such calculations, in which case only the items identified shall be deemed to be in dispute and the other items shall be deemed to be accepted; provided, however, that the only bases for objection with respect to the Adjusted EBITDA calculation shall be (1) non-compliance with GAAP or the Company Accounting Principles, as applicable, or the definition of “Adjusted EBITDA” or the related defined terms, (2) computational errors or (3) Buyer’s non-compliance with the last sentence of Section 1.08(f). Seller shall be deemed to have accepted the Adjusted EBITDA Statement in its entirety, and to have agreed with all items and amounts contained in the Adjusted EBITDA Statement and Buyer’s calculations of the Adjusted EBITDA, if it fails to deliver such notice and explanation of any items it disputes at or before the end of such 60-day review period. Within a further period of twenty (20) days from the end of the aforementioned review period, the parties and their accountants will attempt to resolve in good faith any disputed items.

(ii) Failing such resolution, either Seller or Buyer may refer the unresolved disputed items for final binding resolution to the Dispute Accountants to review this Agreement and the disputed items or amounts for the purpose of calculating the Adjusted EBITDA. In making such calculations, the Dispute Accountants shall consider only those items or amounts in the Adjusted EBITDA Statement or the calculations of the Adjusted EBITDA as to which Buyer and Seller have disagreed and shall be instructed that it may not resolve any amounts in dispute such that the resolution is greater than the greatest amount proposed by the parties or less than the least amount proposed by the parties. The Dispute Accountants shall deliver to Buyer and Seller, within thirty (30) days of reference of the matter to the Dispute Accountants, a report setting forth its calculations, which shall be prepared in accordance with

the standards set forth in Section 1.08(a). The decision of such Dispute Accountants will be final, conclusive and binding upon the parties and will not be subject to collateral attack for any reason. The cost of such review and report shall be paid half by Buyer and half by Seller.

(iii) In the event the Dispute Accountants refuse the engagement under this Section 1.08(b), Buyer and Seller shall mutually agree on an Alternative Dispute Accountant to resolve any disputes according to this Section 1.08(b). If within thirty (30) days, Buyer and Seller fail to mutually agree on an Alternative Dispute Accountant, Buyer and Seller shall thereafter promptly cause the American Arbitration Association to appoint the Alternative Dispute Accountant, and in making its determination with respect to such appointment, the American Arbitration Association shall take into account, and attempt to avoid appointing an accounting firm with, any significant preexisting relationship with the Company Group, Buyer or Seller or their respective Affiliates. The fees and expenses of the Alternative Dispute Accountant shall be apportioned in the same manner as described in Section 1.08(b)(ii).

(c) Payment of Supplemental Purchase Price. After the calculation of the Adjusted EBITDA becomes final, conclusive and binding upon the parties in accordance with the provisions of Section 1.08(b), and without any action on the part of Buyer or Seller, in accordance with the LPA the Supplemental Unit shall automatically convert into the number of Common Units set forth in this Section 1.08(c), which Common Units shall be delivered by Buyer in accordance with this Section 1.08(c) upon conversion of the Supplemental Unit. Within five (5) Business Days after the calculation of the Adjusted EBITDA becomes final, conclusive and binding upon the parties in accordance with the provisions of Section 1.08(b) subject to Buyer’s right to withhold, set-off and apply amounts in accordance with Section 9.04, Buyer shall deliver (i) to Seller ninety percent (90%) of the number of Common Units arrived at by dividing the Supplemental Purchase Price by the VWAP as of December 31, 2014 (rounded up or down to the nearest whole Common Unit, with any 5 in the first decimal place being rounded up), and (ii) to the Escrow Agent the remaining ten percent (10%) of the number of Common Units arrived at by dividing the Supplemental Purchase Price by the VWAP as of December 31, 2014 (rounded up or down to the nearest whole Common Unit, with any 5 in the first decimal place being rounded up), which ten percent (10%) amount shall be deposited into the Additional Indemnity Escrow Account to be held and disbursed in accordance with the terms governing such Additional Indemnity Escrow Account under the Escrow Agreement, provided, that, if the Supplemental Purchase Price is zero, in accordance with the LPA the Supplemental Unit shall be canceled and extinguished and Seller will not be entitled to receive any Common Units or other amount in substitution for the Supplemental Unit. The delivery of the Common Units shall be made by delivery of certificates representing such Common Units (in the case of Seller) and a statement of holdings of Common Units in book-entry form (in the case of the Escrow Agent). At the option of Buyer, all of such Common Units delivered to Seller or the Escrow Agent may be redeemed for cash in accordance with the LPA. Buyer may exercise such right of redemption by delivering written notice of such exercise to Seller within five (5) Business Days of the date that the calculation of the Adjusted EBITDA becoming final, conclusive and binding upon the parties in accordance with the provisions of Section 1.08(b). Seller agrees that the Supplemental Unit shall not be transferrable in whole or in part and the Common Units received in substitution for the Supplemental Unit shall be subject to the resale restrictions set forth in Section 8.02.

(d) Supplemental Option. Notwithstanding anything to the contrary set forth in this Agreement and prior to the delivery of Common Units upon conversion of the Supplemental Unit in accordance with Section 1.08(c), Buyer shall have the option (the “Supplemental Option”) to either (i) redeem the Supplemental Unit for an amount equal to Fifty Million Dollars ($50 million) (the “Supplemental Redemption Amount”) in immediately available funds or (ii) convert the Supplemental Unit into a number of Common Units arrived at by dividing the Supplemental Redemption Amount by the VWAP as of the date of the Supplemental Option Notice (rounded up or down to the nearest whole Common Unit, with any 5 in the first decimal place being rounded up) (in either case, the “Supplemental Payment”), in either case, in accordance with the terms of the LPA. If Buyer elects to exercise such option, it shall deliver written notice thereof (the “Supplemental Option Notice”) to Seller and the Supplemental Option shall be deemed to be exercised upon such delivery. Subject to Buyer’s right to withhold, set-off and apply amounts in accordance with Section 9.04, within five (5) Business Days of the date of the Supplemental Option Notice, Buyer shall deliver ninety percent (90%) of the Supplemental Payment to Seller and the remaining ten percent (10%) of the Supplemental Payment to the Escrow Agent, which ten percent (10%) amount shall be deposited into the Additional Indemnity Escrow Account to be held and disbursed in accordance with the terms governing such Additional Indemnity Escrow Account under the Escrow Agreement. The delivery of any Common Units comprising the Supplemental Payment shall be made by delivery of certificates representing such Common Units (in the case of Seller) and a statement of holdings of Common Units in book-entry form (in the case of the Escrow Agent). No fractional Common Units will be delivered to Seller or the Escrow Agent under this Section 1.08(d). Any such fractional Common Unit shall be rounded up or down to the nearest whole Common Unit, with any 5 in the first decimal place being rounded up. Upon the completion of the Supplemental Payment to Seller, Buyer shall have no further obligation to pay any further Supplemental Purchase Price.

(e) No Duplication of Payments. For the avoidance of doubt, in no circumstance shall Buyer be required to pay both the Supplemental Purchase Price and the Supplemental Payment. In the event that a Supplemental Option Notice is delivered, Buyer will be required to make the Supplemental Payment and will not be required to pay the Supplemental Purchase Price under any circumstances.

(f) Buyer Discretion. Seller understands and acknowledges that control of all business decisions regarding the Company Group (including, without limitation, sales and marketing, capital expenditures, product pricing, product development, product deployment, employee hiring and retention, subcontracting authority, facilities management and acquisitions or dispositions of assets (and the timing thereof)), from and after the Closing Date shall be the ultimate right of the board of directors of the General Partner, and that Buyer may operate its business and the business of its Subsidiaries (including the Company Group) in the manner it deems appropriate. Notwithstanding the foregoing, Buyer shall not take any action in bad faith with the intent of depriving Seller of the benefit of the Supplemental Purchase Price provided for herein.

(g) Securities Law Compliance. Notwithstanding anything to the contrary in this Agreement, Buyer shall not be required to issue Common Units to Seller under Section 1.08(c) or 1.08(d) unless, as reasonably requested by Buyer, prior to receiving such Common

Units, Seller executes and delivers to Buyer one or more documents representing as to certain matters in support of the exemption, acknowledging the restricted nature of such Common Units and representing that Seller is an “accredited investor” as defined in Rule 501(a) promulgated under the Securities Act.

(h) Mergers, Consolidations, etc.

(i) If (A) Buyer effects any merger or consolidation of Buyer with or into another entity, (B) Buyer effects any sale of all or substantially all of its assets in one or a series of related transactions, (C) any tender offer or exchange offer (whether by Buyer or another person or entity) is completed pursuant to which holders of Common Units are permitted to tender or exchange their units for other securities, cash or property, or (D) Buyer effects any reclassification of the Common Units or any compulsory unit exchange pursuant to which the Common Unit is effectively converted into or exchanged for other securities, cash or property (each, a “Fundamental Transaction”), then in lieu of any Common Units Seller may be entitled to receive under this Section 1.08 following the Fundamental Transaction, Seller shall have the right to receive (subject to the conditions to the issuance of such Common Units hereunder) the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been the holder of such Common Units immediately prior to the Fundamental Transaction; provided, however, that Buyer may not engage in any Fundamental Transaction unless the counterparty to any such Fundamental Transaction executes an agreement acknowledging the foregoing. Notwithstanding the foregoing, if the holders of Common Units in any such Fundamental Transaction are afforded an election or are otherwise permitted or required to exchange such Common Units for two or more alternate forms of consideration, then after such Fundamental Transaction Seller shall have the right to receive the same amount and kind of securities, cash or property for which a holder of Common Units would have been entitled to receive if it failed to exercise such rights of election (provided that, if the amount and kind of securities, cash or property receivable upon such Fundamental Transaction is not the same for each Common Unit in respect of which such rights of election shall not have been exercised (a “non-electing unit”), then for the purpose of this Section 1.08(h), the amount and kind of securities, cash or property receivable by Seller after such Fundamental Transaction shall be deemed to be the amount and kind so receivable per unit by a plurality of the holders of non-electing units).

(ii) In the event that, prior to December 31, 2014, Buyer or its Subsidiaries sells the Operating Subsidiary or all or substantially all of its assets (which shall, in any event, include the Facility) (whether such sale is structured as a sale of equity, a sale of assets, a merger or otherwise) to a third party purchaser that is not an Affiliate of Buyer (which shall not include Lender or any other lender of Buyer or any of its Affiliates) (a “Subsequent Purchaser”), Buyer will require the Subsequent Purchaser to assume, effective upon the closing of such sale, the obligations under this Agreement with respect to the payment of the Supplemental Purchase Price (replacing Buyer with the identity of the Subsequent Purchaser and making other reasonable modifications in light of the sale); provided, however, that such Subsequent Purchaser shall be required to pay the entire Supplemental Purchase Price in cash; and provided, further, that Buyer shall nonetheless remain liable for such obligations (which may be satisfied with Common Units) in the event they are not performed by the Subsequent Purchaser.

Any imputed interest shall be determined pursuant to applicable law. The parties agree to file (and to cause the Company to file) all Tax Returns consistent with the foregoing treatment and not to take any position inconsistent therewith in connection with any audit, examination, judicial or administrative proceeding or controversy with any applicable Tax authority, including the IRS, unless otherwise required by applicable

Law; provided, however, that, subject to Section 8.04(g), neither Party shall be required to litigate before any court any proposed deficiency, assessment or adjustment by any governmental entity challenging the foregoing treatment.

(b) Buyer, the Company Group, and Seller agree that the Purchase Price paid to Seller and the liabilities of the Company Group (plus other relevant items) will be allocated to the assets of the Company Group for all purposes (including Tax and financial accounting) as shown on the allocation schedule to be prepared by Buyer and submitted to Seller within one hundred twenty (120) days after the Closing Date (the “Allocation Schedule”). The Allocation Schedule shall be prepared in accordance with Section 1060 of the Code and the Treasury Regulations promulgated thereunder (and any similar provision of state, local or foreign law, as appropriate) and the principles set forth on Schedule 1.09(b). The Allocation Schedule shall be final and binding on the parties unless, within thirty (30) calendar days after delivery thereof to Seller, Seller delivers a written notice to Buyer of its objections to the Allocation Schedule, in which case Buyer and Seller shall attempt in good faith to resolve such dispute between them.

In the case of such dispute, the Dispute Accountants shall be directed to resolve any disputes consistent with this Section 1.09(b) and the principles set forth on Schedule 1.09(b). Buyer, the Company Group, and Seller shall file all Tax Returns (including IRS Form 8594 and amended returns and claims for refund) and information reports in a manner consistent with such allocation and shall not take any position inconsistent therewith in connection with any audit, examination, judicial or administrative proceeding or controversy with any applicable Tax authority, including the IRS, unless otherwise required by applicable law; provided, however, that, subject to Section 8.04(g), neither Party shall be required to litigate before any court any proposed deficiency, assessment or adjustment by any governmental entity challenging the Allocation Schedule.

(c) Buyer will elect the remedial method of Treasury Regulations section 1.704-3(d) as to all relevant assets of the Company; provided, however, Buyer will elect the depreciation methods for U.S. federal income and other applicable tax purposes with respect to all relevant assets of the Company (whether attributable to the Common Units received at Closing or the Common Units received upon conversion of the Supplemental Unit) as set forth in Schedule 1.09(b) and in accordance with the principles set forth thereon. All other determinations regarding the application of Section 704(c) of the Code, the determination and maintenance of capital accounts and other tax matters relating to such assets shall be made in the discretion of Buyer in accordance with the terms of the LPA, except that the parties shall agree that (i) the Percentage Interest with respect to the Supplemental Unit shall at all times be zero and (ii) the Percentage Interest of Seller with respect to Common Units received upon conversion of the Supplemental Unit shall be determined immediately upon receipt of such Common Units.

(d) In accordance with the terms of the LPA, Seller shall be treated as making a Capital Contribution to Buyer in an amount equal to the Net Agreed Value corresponding to the assets (or portions thereof) contributed to Buyer in exchange for the Common Units and the Supplemental Unit. The Net Agreed Value corresponding to the assets (or portions thereof) contributed to Buyer in exchange for the Common Units shall be equal to the aggregate dollar

value of the Initial Equity Purchase Price and the Net Agreed Value corresponding to the assets (or portions thereof) contributed to Buyer in exchange for the Supplemental Unit shall be One Hundred Thousand Dollars ($100,000). Provided that Seller is issued Common Units upon conversion of the Supplemental Unit in accordance with Section 1.08, Buyer covenants to use commercially reasonable efforts to revalue its property and make corresponding adjustments to the capital accounts in accordance with Treasury Regulations sections 1.704-1(b)(2)(iv)(f) and (g) and Section 5.3(d) of the LPA as soon as practicable following the issuance of such Common Units; provided, however, that nothing in the foregoing shall be deemed to restrict the manner in which Buyer may conduct its business.

(e) Buyer and Seller hereby agree (i) for the avoidance of doubt, the Closing Date Bonus Payment, the Final Pension and Retiree Liability, the ▇▇▇▇▇▇▇▇ Closing Payment, the ▇▇▇▇▇▇▇▇ Employment Release Payment and the ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ Amount are expressly assumed by Buyer (subject to Seller’s indemnification obligations set forth in Section 9.02(a)(vii) and except to the extent such amounts are repaid to Seller (if at all) in accordance with Section 8.06), (ii) Seller shall treat the Closing Date Bonus Payment, the Final Pension and Retiree Liability as amounts realized and attributable to the part-sale of assets in accordance with Section 1.09(a) above, and (iii) that Seller shall claim the Closing Date Bonus Payment, the Final Pension and Retiree Liability, the ▇▇▇▇▇▇▇▇ Closing Payment, the ▇▇▇▇▇▇▇▇ Employment Release Payment and the ▇▇▇▇▇▇▇ Severance Amount as deductible by Seller on its income Tax Return for the applicable tax year(s), to the extent permitted by the Code and the Treasury Regulations (including Treasury Regulation section 1.461-4(d)(5)) promulgated thereunder. Buyer hereby agrees not to claim deductions for the payment of the Closing Date Bonus Payment, the Final Pension and Retiree Liability, the ▇▇▇▇▇▇▇▇ Closing Payment, the ▇▇▇▇▇▇▇▇ Employment Release Payment or the ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ Amount, in each case, to the extent deductible by Seller in accordance with the previous sentence.

(f) The General Partner may adopt such conventions, make such allocations and make such amendments to the LPA as provided in Section 6.1(b)(x) of the LPA only if such conventions, allocations or amendments would not have a material adverse effect on Seller as the holder of the Common Units constituting the Initial Equity Purchase Price issued to it pursuant to this Agreement and if such allocations are consistent with the principles of Section 704 of the Code.

Section 1.10 Withholding. Buyer shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to Seller such amounts as Buyer is required to deduct and withhold under the Code, or any Tax law, with respect to the making of such payment. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding was made.

All of the Interests, Operating Subsidiary Interests and Agrifos SPA Interests have been duly authorized and validly issued, and are fully paid and non-assessable.

(a) Seller agrees that, other than transfers to Permitted Transferees and subject to Section 8.02(g), it shall not sell or otherwise transfer any of the Common Units included as part of the Initial Equity Purchase Price during the Lock-Up Period. Buyer may impose stop-transfer instructions and may stamp any certificate (or statement of holding in book-entry form) representing such Common Units issued as part of the Initial Equity Purchase Price with the following legend until the end of the Lock-Up Period:

(e) Notwithstanding the foregoing, Buyer shall take such action as Seller or any Permitted Transferee may reasonably request, including, without limitation, removing any stop transfer instructions and/or removing or causing to be removed any restrictive legend described herein and issuing or causing to be issued Common Unit certificates (or statements of holding in book-entry form) without a restrictive legend to Seller or a Permitted Transferee or their designees (including, in either case, Buyer causing its counsel to issue to its transfer agent any necessary legal opinions in connection therewith, subject to receipt of any customary representation letter required from Seller), all to the extent required from time to time to enable such Person to sell Common Units without registration under the Securities Act in accordance with Rule 144 under the Securities Act (“Rule 144”) and subject to any applicable limitations otherwise expressly provided in this Agreement. Upon the request of Seller or any Permitted Transferee in connection with such Person’s sale of Common Units pursuant to Rule 144, Buyer shall deliver to such person a written statement confirming its compliance with such requirements.

Notwithstanding the foregoing, Buyer’s obligations under this clause (f) with respect to any Common Units issued hereunder shall terminate one (1) year after such issuance.

(g) Notwithstanding the foregoing, the restrictions on Seller and its Permitted Transferees contained in this Section 8.02 shall terminate and become null and void upon the earlier to occur of: (i) the consummation by Buyer of a transaction or series of transactions with any Person or group other than Rentech, Inc. and its Affiliates involving a consolidation, amalgamation, merger, tender offer or similar transaction involving Buyer that would result in such Person or group beneficially owning more than fifty percent (50%) of the outstanding voting securities of Buyer; (ii) the acquisition by any Person or group other than Rentech, Inc. and its Affiliates by means of a tender offer, exchange offer or similar transaction of more than fifty percent (50%) of the outstanding voting securities of Buyer; or (iii) the consummation by Buyer or one or more of its Subsidiaries of a sale, lease or other conveyance of all or a majority of the assets of Buyer and its Subsidiaries, taken as a whole.

Section 8.04 Other Tax Matters.

(a) Tax Periods Ending on or before Closing Date. Seller shall prepare or cause to be prepared and file or cause to be filed all income Tax Returns for the Company Group for all periods ending on or prior to the Closing Date that are filed after the Closing Date.

The parties agree that the books of the Company Group shall close as of the end of the Closing Date.

(b) Straddle Tax Periods. Buyer shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Company relating to Straddle Periods that are filed after the Closing Date. With respect to Tax Returns that relate to a Straddle Period, Buyer shall permit Seller to review and comment on each such Tax Return prior to filing and shall make such revisions to such Tax Returns as are reasonably requested by Seller, subject to Buyer’s approval (which shall not be unreasonably withheld). Pursuant to its obligations in

Section 8.04(c), Seller shall remit, at least three (3) Business Days prior to the due date (with all extensions) for each such Tax Return, the amount allocable to Seller unless such amount was taken into account in the calculation of the Final Net Working Capital.

(c) Indemnification. Subject to Section 9.02(b)(i), Seller shall indemnify the Company and Buyer and hold them harmless from and against (i) all Taxes (or the non-payment thereof) of the Company Group for all taxable periods ending on or before the Closing Date; (ii) with respect to all Straddle Periods, all Taxes imposed on the Company Group that are allocable, pursuant to Section 8.04(d), to the portion of a Straddle Period ending on (and including) the Closing Date; (iii) all Taxes (or the non-payment thereof) of Seller for all taxable periods and (iv) any and all Taxes of any Person (other than the Company Group) imposed on the Company Group as a transferee or successor, by contract or pursuant to any Law, rule or regulation, which Taxes relate to an event or transaction occurring before the Closing Date; provided, however, that Seller shall not be required to indemnify Buyer for any Taxes that were accrued as part of the Final Net Working Capital or included with the Company Group Closing Payment. Buyer shall indemnify Seller and hold it harmless from and against (A) all Taxes (or the non-payment thereof) of the Company Group for all taxable periods beginning after the Closing Date; (B) with respect to all Straddle Periods, all Taxes imposed on the Company Group that are allocable, pursuant to Section 8.04(d), to the portion of a Straddle Period beginning after the Closing Date; and (C) any and all Taxes of any Person (other than the Company) imposed on the Company Group as a transferee or successor, by contract or pursuant to any Law, rule or regulation, which Taxes relate to an event or transaction occurring after the Closing Date. In the event of a conflict between a provision in this Section 8.04(c) and a provision in Section 9.02, the provision in this Section 8.04(c) shall control.

(d) Straddle Period. In the case of any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”), the amount of any Taxes for the pre-Closing and post-Closing portions of such Straddle Period shall be determined as follows: The portion of any Tax that is allocable to the taxable period that is deemed to end on the Closing Date will be: (i) in the case of real property Taxes, personal property Taxes and similar ad valorem Taxes, deemed to be the amount of such Taxes for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of calendar days of such Straddle Period in the portion of the Straddle Period ending on (and including) the Closing Date and the denominator of which is the number of calendar days in the entire Straddle Period, and (ii) in the case of all other Taxes, determined as though the taxable year of the Company terminated at the close of business on the Closing Date; and

(e) Refunds. Any Tax refunds that are received by Buyer or the Company that relate to a Tax that was either paid by the Company or any member of the Company Group on or before the Closing Date or accrued as part of the Final Net Working Capital or included with the Company Group Closing Payment shall be for the account of Seller, and Buyer shall pay over to Seller the amount of any such refund within fifteen (15) days after receipt thereof.

(f) Contests. In the case of an audit or administrative or judicial proceeding that relates to periods ending on or before the Closing Date or for which Buyer may seek indemnity from Seller, Seller shall have the right, at its expense, to participate in and control the conduct of such audit or proceeding but only to the extent that such audit or proceeding relates to

a potential adjustment for which Seller has acknowledged liability to Buyer under this Agreement. Seller shall keep Buyer fully informed of the progress of any such audit or proceeding, and Buyer may also participate in any such audit or proceeding at its expense. Notwithstanding the foregoing, Seller may not pay, discharge, settle, compromise or otherwise dispose of any audit or proceeding with respect to the Company Group without the prior written consent of Buyer (which consent shall not be unreasonably withheld or delayed); provided that no Buyer consent shall be required to settle or otherwise dispose of the Sales and Use Tax Audits in the event that Buyer and the Company Group are not financially liable and no wrongdoing on behalf of Buyer or the Company Group is admitted in connection with such settlement or disposition. If Seller does not assume the defense of any such audit or proceeding promptly, Buyer may defend and settle the same (for Seller’s account and at Seller’s expense) in such reasonable manner as it may deem appropriate. In the event that a potential adjustment as to which Seller would be liable is present in the same proceeding as another potential adjustment for which Buyer would be liable, Buyer shall have the right, at its expense, to control such audit or proceeding. With respect to a potential adjustment for which both Seller, on the one hand, and Buyer or the Company Group, on the other hand, could be liable, or which involves an issue that recurs or affects related tax items for any period ending after the Closing Date (whether or not the subject of audit as such time), (i) both Buyer and Seller may participate in the audit or proceeding, each at its own expense, and (ii) the audit or proceeding shall be controlled by Buyer. Notwithstanding the foregoing, Buyer may not pay, discharge, settle, compromise or otherwise dispose of any audit or proceeding with respect to a potential adjustment for which Seller could be liable without the prior written consent of Seller (which consent shall not be unreasonable withheld or delayed); provided that no Seller consent shall be required in the event that Seller is not financially liable and no wrongdoing on behalf of Seller is admitted. In the event of a conflict between a provision in this Section 8.04(f) and a provision in Section 9.07, the provision in this Section 8.04(f) shall control.

(g) Cooperation on Tax Matters. Buyer, the Company Group and Seller shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns and any audit, litigation or other Proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information reasonably relevant to any such audit, litigation, or other Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Buyer, the Company Group and Seller agree (i) to retain all books and records with respect to Tax matters pertinent to the Company Group relating to any taxable period beginning before the Closing Date until expiration of the statute of limitations (and, to the extent notified by Buyer or Seller, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (ii) to give the other party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, Buyer, the Company Group or Seller, as the case may be, shall allow the other party to take possession of such books and records. Buyer and Seller further agree, upon request, to use their best efforts to obtain any certificate or other document from any Governmental Entity or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including with respect to the transactions contemplated hereby).

Section 8.05 Confidentiality.

(a) All confidential information relating to the Company Group or the Business of which Seller is aware as a result of its involvement with the Company Group before Closing shall be treated as the sole property of the Company Group, and Seller shall use all reasonable efforts to keep confidential all of such information. The obligation to keep such information confidential shall not apply to: (i) any information which is or becomes known to the public through no fault of Seller; (ii) disclosures in accordance with applicable Law or an Order of a Governmental Entity; (iii) any disclosures to Representatives of Seller who have a need to know in connection with the transactions contemplated by this Agreement and that agree to maintain confidentiality of such information in accordance with this Agreement; or (iv) in connection with disputes relating hereto which arise between the parties.

(b) The parties agree to maintain, and to cause their Representatives to maintain, the confidentiality of the terms and conditions of this Agreement and the Related Agreements and all documents executed and delivered in connection with the transactions contemplated by this Agreement and the Related Agreements except to the extent disclosed in any press release permitted by Section 5.05 or any SEC filings required to be made by Buyer. The provisions of this Section 8.05(b) shall not apply to particular conditions or terms of the above referenced documents (i) if the party seeking to make such disclosure shall have obtained the prior written consent of the other party to the disclosure of such conditions or terms, (ii) that are required to be disclosed during the course of any Proceeding which may be brought by either party related to the provisions of any of the above referenced documents, (iii) that are or become generally available to the public other than as a result of actions taken by the party seeking to make such disclosure or its agents or Representatives in violation of this Agreement, or (iv) that are required to be disclosed pursuant to and in accordance with any Law or Order applicable to the party seeking to make such disclosure.

(c) Notwithstanding the foregoing, if a party is requested or required (by oral questions, interrogatories, requests for information or document subpoena, civil investigative demand or similar process) to disclose any of the above-referenced documents or confidential information, such party will promptly notify the other party of such request so that such other party may seek an appropriate protective order, at its sole expense, or waive compliance with the provisions hereof. If, in the absence of a protective order or the receipt of a waiver hereunder, a party is nonetheless, upon the advice of its counsel, under an obligation to disclose any terms or conditions of the above-referenced documents or any confidential information to any Governmental Entity or else stand liable for contempt or suffer other censure or penalty, such party may disclose such documents or information to such Governmental Entity without liability hereunder.

Section 8.06 Closing Date Bonus Payment; ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇▇ Payments.

(a) Schedule 8.06 sets forth a true and accurate list, for each individual eligible to receive any payment under the Bonus Plans, as applicable, such individual’s: name; salary or annual wage rate (including the date and amount of any 2012 adjustment thereto); 2012 or quarterly EBITDA target bonus (as a percentage of salary or annual wage rate) and projected percentage attainment thereof; 2012 or quarterly Safety/Environmental target bonus (as a

Buyer agrees that, on or prior to January 31, 2013, it shall pay (or cause to be paid) to the Company Group, for the benefit of the Company Group’s employees set forth on Schedule 8.06 (as such Schedule shall be updated by Seller in the event the Closing Date occurs after October 31, 2012), an amount equal, in the aggregate, to the Closing Date Bonus Payment. Each such employee shall be paid a portion of the Closing Date Bonus Payment equal to his or her Estimated Closing Date Bonus (net of applicable withholding taxes), provided, however, that notwithstanding the foregoing, to the extent that any employee ceases to be eligible to receive his/her respective Estimated Closing Date Bonus as of the payment date (as determined by Buyer), then any such portion of the Closing Date Bonus Payment that would otherwise have been paid to such employee shall instead be paid by Buyer to all other employees then-receiving payments under such quarterly or annual component of the Bonus Plans, as applicable, on a pro rata basis. Buyer and Seller agree that, except as set forth in Section 9.02(a)(viii), Seller shall have no other liability with respect to any amounts that may be owed under the Bonus Plans for calendar year 2012.

(b) At Closing, Seller shall provide Buyer with sufficient funds to pay each of the ▇▇▇▇▇▇▇▇ Closing Payment, the ▇▇▇▇▇▇▇▇ Employment Release Payment and the ▇▇▇▇▇▇▇ Severance Amount plus, in each case, the employer’s share of FICA and Medicare taxes and any comparable state and local taxes payable with respect thereto. Buyer agrees that it shall pay on behalf of Agrifos Fertilizer L.L.C. (or cause Agrifos Fertilizer L.L.C. to pay), in accordance with the terms and conditions of the ▇▇▇▇▇▇▇▇ Employment Agreement or the ▇▇▇▇▇▇▇ Agreement, as applicable, each of the ▇▇▇▇▇▇▇▇ Closing Payment, the ▇▇▇▇▇▇▇▇ Employment Release Payment and the ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ Amount, in each case, net of all applicable wage withholding and the employee’s share of FICA and Medicare taxes and any comparable state and local taxes. If any or all of the ▇▇▇▇▇▇▇▇ Closing Payment, the ▇▇▇▇▇▇▇▇ Employment Release Payment and/or the ▇▇▇▇▇▇▇ Severance Amount fails to become payable in accordance with the ▇▇▇▇▇▇▇▇ Employment Agreement or the ▇▇▇▇▇▇▇ Agreement, as applicable, Buyer shall promptly, but in any event within thirty (30) days after the date on which such amount or amounts are forfeited by the applicable executive, pay to Seller an amount equal to such forfeited amount plus the employer’s share of FICA and Medicare taxes and any comparable state and local taxes paid by Seller to Buyer with respect thereto. Buyer and Seller agree that, except as set forth in Section 9.02(a)(viii) or to the extent refunded to Seller in accordance with this Section 8.06(b), Seller shall have no other liability with respect to the ▇▇▇▇▇▇▇▇ Closing Payment, the ▇▇▇▇▇▇▇▇ Employment Release Payment or the ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ Amount.

(iii) any Liabilities arising (regardless of when arising) out of, based upon, resulting from or incident to (A) the ownership or operation of the Spin-Off Assets on, prior to or after the Closing or (B) the spin-off of the Spin-Off Assets pursuant to Section 5.08;

(iv) any and all Company Debt to the extent not included in the Final Closing Date Indebtedness;

(v) any and all Transaction Expenses to the extent not included in the Final Transaction Expenses;

(vi) subject to Schedule 9.02, (A) any Environmental Claim or obligation under any Environmental Law concerning (1) any Facility or (2) the Handling of Substances by the Company Group or in connection with the Business, in the case of each of clauses (1) or (2), accruing or arising out of, based upon, resulting from or incident to events or circumstances in existence on or prior to the Closing; (B) the Gyp Stack Closing Liability; and (C) the removal of any NORM existing on or in any Existing Gypsum Stacks as of the Closing Date, except for Losses to the extent arising out of, based upon, resulting from or incident to any Environmental Claim concerning actions taken by Buyer or the Company Group after the Closing;

(vii) the Sales and Use Tax Liability; provided, however, that Seller shall not be required to indemnify the Buyer Indemnified Parties for any such amounts that were accrued as part of the Final Net Working Capital or included within the Company Group Closing Payment; and

(viii) any Third-Party Claim brought by an employee of the Company Group asserting that the Estimated Closing Date Bonus set forth on Schedule 8.06 with respect to such employee is less than the portion of the Plant Bonus Liability attributable to such employee; provided, however, that Seller shall not be required to indemnify the Buyer Indemnified Parties for any portion of (A) the Plant Bonus Liability to the extent it was included as part the Closing Date Bonus Payment or (B) any claim brought by (1) ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ asserting that he has been paid less than the amount of the ▇▇▇▇▇▇▇▇ Closing Payment or the ▇▇▇▇▇▇▇▇ Employment Release Payment or (2) ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ asserting that he has been paid less than the amount of the ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ Amount, in the case of payments described in clause (B) of this Section 9.02(a)(viii), to the extent payable in accordance with the ▇▇▇▇▇▇▇▇ Employment Agreement or the ▇▇▇▇▇▇▇ Agreement, as applicable, and net of applicable wage withholding and the employee’s share of FICA and Medicare taxes and any comparable state and local taxes.

(b) Notwithstanding anything to the contrary in this Agreement, the rights to indemnification under this Article IX and Section 8.04 are subject to the following limitations; provided, however, that the following limitations described in clauses (i), (ii) and (iii) below shall not apply to Losses arising out of fraud or intentional misrepresentation:

(i) Seller shall not have any obligation to indemnify any Buyer Indemnified Party from and against any Losses arising (A) out of breaches or inaccuracies indemnified under Section 9.02(a)(i) (other than as a result of a breach of or inaccuracy in a Fundamental Representation or any of the representations and warranties in Section 3.16 (Employee Benefit Plans) or Section 3.19 (Taxes)) or (B) from Environmental Claims and obligations under Section 9.02(a)(vi) until the Buyer Indemnified Parties have suffered aggregate Losses in excess of Two Million Dollars ($2 million) (the “Deductible”), in which event the Buyer Indemnified Party shall be entitled to indemnification for only the amount of Losses that

exceed the Deductible. Seller shall not have any obligation to indemnify any Buyer Indemnified Party from and against any Losses arising out of breaches of or inaccuracies in the representations and warranties set forth in Section 3.16 (Employee Benefit Plans) until the Buyer Indemnified Parties have suffered aggregate Losses in excess of Fifty Thousand Dollars ($50,000) (the “ERISA Deductible”), in which event the Buyer Indemnified Party shall be entitled to indemnification for only the amount of Losses that exceed the ERISA Deductible. Seller shall not have any obligation to indemnify any Buyer Indemnified Party from and against any Losses arising out of breaches of or inaccuracies in the representations and warranties set forth in Section 3.19 (Taxes) or any Losses indemnified under Section 8.04 (Other Tax Matters) (in each case, other than with respect to income Taxes or the Sales and Use Tax Liability) until the Buyer Indemnified Parties have suffered aggregate Losses in excess of Fifty Thousand Dollars ($50,000) (the “Tax Deductible”), in which event the Buyer Indemnified Party shall be entitled to indemnification for only the amount of Losses that exceed the Tax Deductible. For the avoidance of doubt, the rights of Buyer Indemnified Parties to indemnification with respect to the following shall not be subject to the Deductible, ERISA Deductible or Tax Deductible: (1) Section 9.02(a)(i) as a result of a breach of or inaccuracy in a Fundamental Representation or with respect to income Taxes or the Sales and Use Tax Liability, (2) Section 9.02(a)(vii) with respect to the Sales and Use Tax Liability, (3) Section 9.02(a)(viii) with respect to the Plant Bonus Liability, and (4) Section 8.04 with respect to income Taxes or the Sales and Use Tax Liability.

(ii) The maximum amount which the Buyer Indemnified Parties may recover arising (A) (1) out of breaches or inaccuracies described in Section 9.02(a)(i) (other than as a result of a breach of or inaccuracy in a Fundamental Representation or any of the representations and warranties in Section 3.16 (Employee Benefit Plans) or Section 3.19 (Taxes)) and (2) from Environmental Claims and obligations under Section 9.02(a)(vi) shall be an aggregate of Twenty Nine Million Dollars ($29 million) (the “Cap”); provided, however, that upon the occurrence of a Triggering Event, the Cap shall be reduced to an amount equal to (I) Nineteen Million Dollars ($19 million), plus (II) the amount of any Losses (up to a maximum of Ten Million Dollars ($10 million)) subject to indemnification under Section 9.02(a)(vi)(B) or (C) incurred prior to, or arising out of, based upon, resulting from or incident to a Claim made by ExxonMobil or a Governmental Authority prior to, the occurrence of the Triggering Event (such amount, the “Reduced Cap”). For the avoidance of doubt, any Losses subject to the Cap under this Section 9.02(b)(ii) incurred prior to the occurrence of the Triggering Event shall be applied to the Reduced Cap under this Section 9.02(b)(ii). For the avoidance of doubt, the Buyer Indemnified Parties’ right to indemnification under Section 9.02(a)(i) as a result of a breach of or inaccuracy in a Fundamental Representation and the representations and warranties in Section 3.16 (Employee Benefit Plans) and Section 3.19 (Taxes) shall not be subject to the Cap or the Reduced Cap in this Section 9.02(b)(ii).

(iii) Subject to the other limitations contained herein, the Buyer Indemnified Parties shall satisfy any finally determined claim for indemnification under this Section 9.02 (A) first, from the Escrow Accounts in accordance with the terms set forth in this Agreement and the Escrow Agreement (and to the extent the Escrow Funds in such Escrow Accounts may be used to satisfy such claim), (B) second, if the Escrow Funds in the Escrow Accounts that may be used to satisfy such claim have been exhausted, by set off against the Supplemental Purchase Price Amounts pursuant to Section 9.04(a), and (C) third, if the Escrow

Funds in such Escrow Accounts and the Supplemental Purchase Price Amounts are insufficient to satisfy all such indemnification claims, then from Seller directly. For the avoidance of doubt, nothing in this Section 9.02(b)(iii) shall restrict the Buyer Indemnified Parties’ right to withhold the amount of an Unresolved Indemnification Claim against the Supplemental Purchase Price Amounts under Section 9.04(b).

Section 9.03 Indemnification by Buyer.

(a) After the Closing, Buyer will save, defend and indemnify Seller and its Affiliates and each of their respective employees, directors, officers, representatives, agents, successors and assigns (collectively, the “Seller Indemnified Parties”) from and against, and hold each of them harmless from, any and all Losses arising out of, based upon, resulting from or incident to:

(i) any breach of or inaccuracy in any representation or warranty made by Buyer under this Agreement or any certificate delivered pursuant to Section 6.02(i)(ii);

(ii) any breach of covenant or agreement made by Buyer under this Agreement;

(iii) any Liabilities (including those of the Operating Subsidiary or Agrifos SPA) arising out of, based upon, resulting from or incident to the ownership, operation or disposal of the Phosphate Assets after the Closing; provided, however, that the Losses subject to indemnification under this Section 9.03(a)(iii) shall exclude any Losses subject to indemnification under Section 9.02(a)(i) or (vi) (other than the cost of disposal of the Phosphate Assets, including the cost of disposal of any asbestos, NORM or other Substances included in or on the Phosphate Assets); and

(iv) any Environmental Claim or obligation under any Environmental Law concerning (A) any Facility or (B) the Handling of Substances by Buyer or the Company Group or in connection with the Business to the extent arising out of, based upon, resulting from or incident to actions taken by Buyer or the Company Group after the Closing; provided, however, that the Losses subject to indemnification under this Section 9.03(a)(iv) shall exclude any Losses subject to indemnification under Section 9.02(a)(i) or (vi), except as otherwise set forth in Schedule 9.02 and except to the extent that any such Losses are attributable to both this Section 9.03(a)(iv) and Sections 9.02(a)(i) or (vi), in which event such Losses shall be apportioned between the parties based upon the pre-Closing contribution to the Loss (which shall be borne by Seller) and the post-Closing contribution to the Loss (which shall be borne by Buyer).

(b) Notwithstanding anything to the contrary in this Agreement, the right to indemnification under this Article IX is subject to the following limitations; provided, however, that the following limitations described in clauses (i) and (ii) below shall not apply to Losses arising out of fraud or intentional misrepresentation:

(i) Buyer shall not have any obligation to indemnify any Seller Indemnified Party from and against any Losses arising out of breaches or inaccuracies described in Section 9.03(a)(i) (other than as a result of a breach of or inaccuracy in a Fundamental

Representation) or for Losses subject to indemnification under Section 9.03(a)(iv) until the Seller Indemnified Parties have suffered aggregate Losses by reason of such breaches or inaccuracies (including as a result of breaches of or inaccuracies in Fundamental Representations) in excess of the Deductible, in which event the Seller Indemnified Party shall be entitled to indemnification for only the amount Losses that exceed the Deductible. For the avoidance of doubt, the Seller Indemnified Parties right to indemnification under Section 9.03(a)(i) as a result of a breach of or inaccuracy in a Fundamental Representation shall not be subject to the Deductible.

(ii) The maximum amount which the Seller Indemnified Parties may recover arising out of breaches or inaccuracies described in Section 9.03(a)(i) (other than as a result of a breach of or inaccuracy in a Fundamental Representation), or for Losses subject to indemnification under Section 9.03(a)(iii) and Section 9.03(a)(iv), shall be the Cap; provided, however, that upon the occurrence of a Triggering Event, the Cap shall be reduced to the Reduced Cap. For the avoidance of doubt, any Losses subject to the Cap under this Section 9.03(b)(ii) incurred prior to the occurrence of the Triggering Event shall be applied to the Reduced Cap under this Section 9.03(b)(ii). For the further avoidance of doubt, the Seller Indemnified Parties right to indemnification under Section 9.03(a)(i) as a result of a breach of or inaccuracy in a Fundamental Representation shall not be subject to the Cap or the Reduced Cap in this Section 9.03(b)(ii).

Section 9.04 Set-Off.

(a) Subject to Section 9.02(b)(iii), the Buyer Indemnified Parties shall be entitled to withhold and set off against the Supplemental Purchase Price Amounts payable to Seller hereunder any amount finally resolved (and not subject to further appeal) to be due from Seller to satisfy a finally determined indemnification claim hereunder (after taking into consideration the applicable limitations contained in Section 9.02(b)). If Common Units are to be issued upon conversion of the Supplemental Unit, such finally resolved amount shall be applied to reduce the Supplemental Purchase Price Amounts that are used to determine the number of the Common Units that may be received by Seller upon conversion of the Supplemental Unit in accordance with Section 1.08(c) or Section 1.08(d).

(b) To the extent that any indemnification claim hereunder of a Buyer Indemnified Party against Seller remains outstanding or unresolved (an “Unresolved Indemnification Claim”) on the date that a Supplemental Purchase Price Amount is required to be paid hereunder, regardless of whether any Escrow Funds in the Escrow Accounts are available at such time to satisfy such Unresolved Indemnification Claim or whether any claim has been made by the Buyer Indemnified Parties with respect thereto, Buyer may withhold from the Supplemental Purchase Price Amount the amount of such Unresolved Indemnification Claim that may be owed or may become payable in the future (after taking into consideration the applicable limitations contained in Section 9.02(b)(i) and (ii)) until such Unresolved Indemnification Claim is ultimately resolved (and not subject to further appeal), although the amount of such Unresolved Indemnification Claim may be contingent or unmatured. In the event that the Buyer Indemnified Party has exercised its right to withhold from the Supplemental Purchase Price Amount the amount of an Unresolved Indemnification Claim, it may not simultaneously request the Escrow Agent to withhold Escrow Funds from Seller for the amount of the same Unresolved Indemnification Claim pursuant to the Escrow Agreement.

(c) Upon ultimate resolution of an Unresolved Indemnification Claim, any amounts withheld in excess of the amount required to satisfy such indemnification claim (the “Released Amount”) shall be promptly released as provided in this Section 9.04(c). Buyer shall deliver ninety percent (90%) of the Released Amount to Seller and the remaining ten percent (10%) of the Released Amount to the Escrow Agent, which ten percent (10%) amount shall be deposited into the Additional Indemnity Escrow Account to be held and disbursed in accordance with the terms governing such Additional Indemnity Escrow Account under the Escrow Agreement. In the event that the Released Amount is comprised of Common Units, no fractional Common Units will be delivered to Seller or the Escrow Agent under the preceding sentence. Any such fractional Common Unit shall be rounded up or down to the nearest whole Common Unit, with any 5 in the first decimal place being rounded up. At the option of Buyer, all of the Common Units delivered to Seller or the Escrow Agent may be redeemed for cash in accordance with the LPA for an amount based on the VWAP as of the date of the ultimate resolution of the Unresolved Indemnification Claim. Buyer may exercise such option by delivering written notice to Seller and the Escrow Agent of Buyer’s election to redeem such Common Units for cash. Seller agrees that such Common Units shall be subject to the resale restrictions set forth in Section 8.02.

Section 9.05 Exclusive Remedy. From and after the Closing Date, the Buyer Indemnified Parties’ and the Seller Indemnified Parties’ sole and exclusive remedy for any Claim with respect to the breach of any representation, warranty, covenant or agreement or other express indemnification obligation set forth in this Agreement shall be those remedies set forth in this Article IX; provided, however, that nothing herein shall preclude any party hereto from (a) enforcing its rights to an injunction or specific performance with respect to the performance of post-Closing agreements or obligations pursuant to Section 11.11 or (b) seeking any remedy based upon fraud or intentional misrepresentation by any other party hereto (including, without limitation, any fraud or intentional misrepresentation committed by any officer, director, member, employee or agent of Seller, the Company Group or any Affiliate thereof in connection with the transactions contemplated by this Agreement).

Section 9.06 Additional Provisions Regarding Indemnification.

(a) Notwithstanding any other provision of this Article IX, the right to indemnification pursuant to this Article IX is subject to the following limitations; provided, however, that the following limitations described in (i), (ii), (iii) and (iv) below shall not apply to Losses arising out of fraud or intentional misrepresentation:

(i) in no event will any party to this Agreement be liable under this Agreement (for indemnification) to any other party or other Person for punitive damages in connection with any Losses, except where such damages are received by a third party from an Indemnified Party in connection with Losses indemnified hereunder;

(ii) the amount of Loss for which any party to this Agreement may be entitled to seek indemnification under this Agreement will be reduced by the amount of any third-party insurance (and not self-insurance) proceeds or other payment from a third party that is actually received by such party (or its Affiliates) with respect to such Loss (net of any out-of-pocket

expenses incurred in obtaining such amounts, any co-payment, retrospective premium adjustment and increased premiums resulting from such Loss (“Reduction Amounts”));

(iii) if an Indemnified Party, after having received any indemnification payment pursuant to this Agreement with respect to a Loss, subsequently actually receives any third-party insurance proceeds or other payment from a third party for which it was actually indemnified pursuant to this Article IX, such Indemnified Party will promptly refund and pay to the Indemnifying Party an amount equal to such insurance proceeds or payment (net of applicable Reduction Amounts); and

(iv) each party to this Agreement (and the Company Group) will use its commercially reasonable efforts to mitigate any Losses with respect to which it may be entitled to seek indemnification pursuant to this Agreement; provided, however, that (A) this clause (iv) shall not require any party to take any action to recover Losses from any third party unless doing so is commercially reasonable; and (b) the taking of any such action shall not be a condition to indemnification rights hereunder.

(b) All indemnification payments pursuant to this Article IX or Article VIII shall be deemed to be adjustments to the Purchase Price for U.S. federal income Tax purposes, except as otherwise required by Law.

Section 9.07 Indemnification Procedures.

(a) Should any Claim or Proceeding by or involving a third party (including any Governmental Entity) not party to this Agreement (or an Affiliate thereof) arise after the Closing Date for which a party (“Indemnifying Party”) has an indemnification obligation under the terms of this Agreement (a “Third-Party Claim”), the other party (“Indemnified Party”) shall notify the Indemnifying Party in writing (a “Third-Party Claim Notice”) within a reasonable time after such Claim or Proceeding arises and is known to the Indemnified Party; provided, however, that no delay on the part of the Indemnified Party to provide the Indemnifying Party a Third-Party Claim Notice shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is actually prejudiced as a result thereof.

(b) If the Indemnifying Party wishes to assume the defense of any Third-Party Claim, the Indemnifying Party shall give written notice to Indemnified Party that it intends to assume such defense within fifteen (15) days after notice from Indemnified Party of such Third-Party Claim, the expenses of which such defense shall be paid, as incurred, by the Indemnifying Party; provided that, as a condition precedent to the Indemnifying Party’s right to assume the defense of such Third-Party Claim, the Indemnifying Party must first acknowledge in writing to the Indemnified Party that the Indemnifying Party will indemnify the Indemnified Party from and against any Losses based upon, arising out of or resulting from such Third-Party Claim. The Indemnifying Party shall thereafter assume the defense of such Third-Party Claim, through counsel reasonably satisfactory to Indemnified Party; provided that Indemnified Party may participate in such defense at its own expense but, in any event, Indemnifying Party shall have the right, as long as it is actively defending any Claim or Proceeding, to control such defense. Notwithstanding the foregoing, if the Indemnified Party reasonably determines based on the advice of counsel that the representation by counsel chosen by the Indemnifying Party creates a

conflict of interest and notifies the Indemnifying Party thereof, the Indemnified Party shall be entitled to participate in the defense of such claim with counsel of its choice for such purpose and the Indemnifying Party shall pay the reasonable fees and expenses of such counsel, as incurred (provided that the Indemnifying Party shall not be required to pay the fees and expenses for more than one such counsel and one local counsel in each relevant jurisdiction for all Indemnified Parties). The Indemnified Party shall reasonably cooperate with Indemnifying Party, its counsel and its other authorized Representatives in connection with the exercise of the rights of Indemnifying Party pursuant to this Section 9.07.

(c) The Indemnifying Party shall be entitled to settle, compromise or consent to the entry of any judgment with respect to any such Third-Party Claim, with the written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed); provided, however, that the prior written consent of the Indemnified Party may be withheld in its sole discretion if such settlement, compromise or consent: (i) involves the payment of money damages (other than money damages constituting the Deductible) that will be paid by the Indemnified Party under this Agreement in connection therewith; (ii) imposes any injunctive or other equitable relief against the Indemnified Party; (iii) requires the finding or admission of any wrongdoing by the Indemnified Party or (iv) does not include an express, unconditional release of the Indemnified Party from any liability or obligation with respect to such Third-Party Claim. If (A) the Indemnifying Party has not assumed the defense of a Third-Party Claim in accordance with Section 9.07(b), (B) the Indemnifying Party fails to appropriately prosecute the defense of any Third-Party Claim that it has previously assumed or fails to pay the reasonable costs and expenses of the defense of any such Third-Party Claim (including fees of counsel), as incurred, or (C) the Third-Party Claim seeks an order, injunction or other equitable relief for other than monetary damages against the Indemnified Party, the Indemnified Party may, by written notice to the Indemnifying Party, assume the exclusive right to defend, compromise or settle such Third-Party Claim with counsel of the Indemnified Party’s selection, but the Indemnifying Party shall have no liability with respect to any compromise, settlement or consent to entry of any judgment with respect to such Third-Party Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed).

(d) If the Indemnifying Party assumes the defense of any Third-Party Claim in accordance with the preceding provisions, the Indemnifying Party will keep the Indemnified Party informed of all material developments relating to or in connection with such Third-Party Claim. If the Indemnifying Party assumes the defense of a Third-Party Claim in accordance with the preceding provisions, the parties hereto will reasonably cooperate in the defense thereof (with the Indemnifying Party being responsible for all reasonable out-of-pocket expenses of the Indemnified Party in connection with such cooperation). If the Indemnifying Party elects not to assume the defense of a Third-Party Claim, the Indemnifying Party’s obligations under this Section 9.07(d) shall apply to the Indemnified Party.

(e) Any claim on account of Losses for which indemnification is provided under this Agreement which does not involve a Third-Party Claim shall be asserted by reasonably prompt written notice (a “Notice of Claim”), stating, in reasonable detail, and to the extent known, the nature and basis of such claim and a good faith, non-binding, preliminary estimate of the aggregate dollar amount of actual Losses that have arisen and are expected to arise as a result of such breach or other matter as set forth on such Notice of Claim, given by the

Indemnified Party to the Indemnifying Party; provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is actually prejudiced as a result thereof.

(f) Upon receipt of a Notice of Claim, the Indemnifying Party and the Indemnified Party shall consult with each other in an attempt to agree upon the matters set forth in the Notice of Claim and reach a written agreement with respect to such matters (a “Claim Settlement Agreement”). If the Indemnifying Party and the Indemnified Party fail to agree upon the matters contained in such Notice of Claim within thirty (30) days after the date the Notice of Claim is delivered to the Indemnified Party, then, at the request of any party, the Indemnifying Party and the Indemnified Party shall meet in an attempt to resolve the objection described in such Notice of Claim and reach a Claim Settlement Agreement. If the Indemnifying Party and the Indemnified Party enter into a Claim Settlement Agreement, the objections contained in such Notice of Claim shall be deemed to be as resolved as provided therein. If the Indemnifying Party and the Indemnified Party are unable to resolve the objection described in such Notice of Claim within sixty (60) days after delivery by the Indemnified Party of such Notice of Claim, then either party may submit the objections contained in such Notice of Claim for resolution in a proceeding commenced as contemplated by Section 11.07.

Section 9.08 Calculation of Loss Amount. For purposes of determining the amount of any Losses with respect to any claim for indemnification under Section 9.02 or Section 9.03 (but not for purposes of determining whether any representation or warranty in this Agreement has been breached), any qualifiers as to materiality (including Company ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ Adverse Effect, Buyer Material Adverse Effect or similar terms), contained in an applicable representation and warranty shall be deemed to be deleted and shall be given no force or effect.

Section 9.09 Easements. If Buyer or the Operating Subsidiary determines and gives notice to Seller, during the applicable survival period, that Seller’s representations and warranties set forth in the second or third sentence of Section 3.11 are inaccurate in any respect, then Seller shall cooperate with Buyer and the Company Group to grant, or cause to be granted, to the Operating Subsidiary, within thirty (30) days of written notice from the Buyer or the Operating Subsidiary, at no cost or expense to Buyer or the Operating Subsidiary, such easements (in recordable form) as are reasonably necessary to provide the Operating Subsidiary with access to and from and ability to use, operate, maintain, repair and replace all of the properties and assets of the Company Group located on the ▇▇▇▇▇ Property as of the date hereof to the extent that the easements reserved to the Operating Subsidiary in the Special Warranty Deed attached hereto as Exhibit Q are insufficient to allow the Operating Subsidiary to use, operate, maintain, repair and replace all of the properties and assets of the Company Group located on the ▇▇▇▇▇ Property as of the date hereof.

Section 11.11 Specific Performance.

(a) Each of the parties to this Agreement acknowledges and agrees that the other party to this Agreement would be irreparably damaged in the event that any of the terms or provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached. Therefore, notwithstanding anything to the contrary set forth in this Agreement, each of the parties to this Agreement hereby agrees that the other parties to this Agreement shall be entitled to an injunction or injunctions to prevent breaches of any of the terms or provisions of this Agreement, and to enforce specifically the performance by the other party under this Agreement, and each party to this Agreement hereby agrees to waive the defense in any such suit that the other parties to this Agreement have an adequate remedy at law, and hereby agrees to waive any requirement to post any bond in connection with obtaining such relief.

(b) Notwithstanding the foregoing or any other provision of this Agreement, including Section 11.11(a) above, the parties hereto acknowledge and agree that Seller shall not be entitled to injunctive relief or to enforce specifically the obligations of Buyer to consummate the transactions contemplated by this Agreement unless (i) all of the conditions set forth in Section 6.01 have been satisfied (other than those conditions that by their nature are to be satisfied by actions taken at Closing, but each of which is more likely than not to be satisfied by actions taken on the Closing Date), (ii) Buyer fails to complete the Closing by November 30, 2012, and (iii) Seller has irrevocably confirmed to Buyer in writing that if the New Financing were funded then Seller would, assuming all of the conditions set forth in Section 6.02 are satisfied, take such actions that are within its control to cause the Closing to occur. For the avoidance of doubt, while Seller may pursue (and plead in the alternative) both a grant of specific performance as expressly permitted by this Section 11.11 and payment of the Termination Fee (only to the extent expressly permitted by Section 11.13(b)), under no circumstances shall Buyer be obligated to both specifically perform the terms of this Agreement and pay the Termination Fee.

Section 11.12 Financing Parties.

federal and New York state courts located in the Borough of Manhattan within New York City; (b) agrees that, except as specifically set forth in the Credit Agreement or the documents evidencing the financings contemplated by the Credit Agreement, all claims or causes of action (whether at law, in equity, in contract, in tort or otherwise) against any of the Financing Parties in any way relating to the Credit Agreement or the performance thereof or the financings contemplated thereby, shall be exclusively governed by, and construed in accordance with, the internal laws of the State of New York, without giving effect to principles or rules or conflict of laws to the extent such principles or rules would require or permit the application of laws of another jurisdiction; and (c) hereby irrevocably and unconditionally waives any right such party may have to a trial by jury in respect of any litigation (whether in law or in equity, whether in contract or in tort or otherwise) directly or indirectly arising out of or relating in any way to the Credit Agreement or the performance thereof or the financings contemplated thereby. Notwithstanding anything to the contrary contained in this Agreement, (i) Seller, its stockholders, their Representatives and their respective subsidiaries, Affiliates, directors, officers, employees, agents partners, managers or members shall not have any rights or claims against any Financing Parties, in any way relating to this Agreement or any of the transactions contemplated by this Agreement, or in respect of any, or in respect of any oral representations made or alleged to have been made in connection herewith or therewith, including any dispute arising out of or relating in any way to the Credit Agreement or the performance thereof or the financings contemplated thereby, whether at law or equity, in contract, or in tort or otherwise and (ii) no Financing Parties shall have any liability (whether in contract, in tort or otherwise) to any of Seller, its stockholders, their Representatives their respective subsidiaries, Affiliates, directors, officers, employees, agents partners, managers or members for any obligations or liabilities of any party hereto under this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby or in respect of any oral representations made or alleged to have been made in connection herewith or therewith, including any dispute arising out of or relating in any way to the Credit Agreement or the performance thereof or the financings contemplated thereby, whether at law or equity, in contract, in tort or otherwise. Notwithstanding anything to the contrary contained in this Agreement, after the Closing, the Financing Parties shall be third-party beneficiaries of, and shall be entitled to, the protections of this provision.

Section 11.13 Fees and Expenses.

(a) Except as otherwise expressly provided herein, Seller and Buyer shall each bear their own costs and expenses incurred in connection with this Agreement, the Related Agreements and the transactions contemplated hereby and thereby. Prior to the Closing Date, the Operating Subsidiary may pay from its available cash any Transaction Expenses. Buyer shall be responsible for fees, commissions, expenses and reimbursements incurred by or required to be paid to its professional advisors and investment bankers, including those payable to Buyer’s Bankers; and at or after the Closing, Seller (not the Company Group) shall bear (from the Purchase Price payments) and be responsible for the fees, commissions, costs, charges, expenses and reimbursements incurred by or required to be paid to the Company Group’s and Seller’s professional advisors and investment bankers, including those payable to Macquarie.

(b) In the event that this Agreement is terminated by Buyer pursuant to Section 10.01(b)(iii) or Seller pursuant to Section 10.01(c)(iii) due to the failure of the condition

set forth in Section 6.01(l) and (i) at the date of such termination all of the conditions set forth in Section 6.01 (other than Section 6.01(l)) have been satisfied or are capable of being satisfied and (ii) upon the request of Buyer, Seller has irrevocably confirmed to Buyer in writing that if the New Financing were funded then Seller would, assuming all of the conditions set forth in Section 6.02 are satisfied, take such actions that are within its control to cause the Closing to occur, then concurrently with such termination, Buyer shall pay Seller by wire transfer of immediately available funds a fee equal to Five Million One Hundred Thousand Dollars ($5.1 million) (the “Termination Fee”).

(c) Buyer and Seller acknowledge and agree that the agreements contained in Section 11.13(b) are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Seller would not enter into this Agreement. Accordingly, if Buyer fails promptly to pay the amount due pursuant to Section 11.13(b), and, in order to obtain such payment, Seller commences a suit that results in a judgment against Buyer for the Termination Fee, Buyer shall pay to Seller its reasonable documented out-of-pocket costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such suit, together with interest on the amount of the Termination Fee, as the case may be, from the date such payment was required to be made until the date of payment at the prime rate of Citibank N.A. in effect on the date such payment was required to be made.

(d) Notwithstanding anything to the contrary in this Agreement, Buyer and Seller expressly acknowledge and agree that, with respect to any termination of this Agreement in circumstances where the Termination Fee is payable in accordance with Section 11.13, the payment of the Termination Fee shall constitute liquidated damages with respect to any claim for damages or any other claim which Seller would otherwise be entitled to assert against Buyer or its Affiliates with respect to this Agreement and the transactions contemplated hereby and shall constitute the sole and exclusive remedy available to Seller. Buyer and Seller expressly acknowledge and agree that, in light of the difficulty of accurately determining actual damages with respect to the foregoing upon any termination of this Agreement in circumstances where the Termination Fee is payable in accordance with Section 11.13, the rights to payment under Section 11.13: (i) constitute a reasonable estimate of the damages that will be suffered by reason of any such proposed or actual termination of this Agreement, and (ii) shall be in full and complete satisfaction of any and all damages arising as a result of the foregoing.

Section 11.14 Certain Conflicts and Waivers. It is acknowledged by each of the parties hereto that Seller, on behalf of itself and the Company Group, has retained various professional advisors (“Seller’s Advisors”), including but not limited to counsel, accountants, actuaries, engineers and environmental consultants to act on behalf of the Company Group in connection with the operations of the Company Group prior to the Closing and/or in connection with the transactions contemplated under this Agreement; provided, however, that Buck Consultants, LLC and PricewaterhouseCoopers LLP shall not be considered “Seller’s Advisors” with respect to the calculation of the Final Pension and Retiree Liability as of the Closing Date pursuant to Section 1.06(b). Buyer hereby agrees that, in the event that a dispute arises after the Closing between the parties hereto, Seller’s Advisors may represent and provide services to Seller in such dispute even though the interests of Seller may be directly adverse to Buyer and the Company Group, and even though Seller’s Advisors may have represented the Company Group in a matter substantially related to such dispute, or may be handling ongoing matters for

the Company Group. Buyer further agrees that, as to all communications prior to Closing among Seller and/or the Company Group on the one hand and any of Seller’s counsel on the other hand, the attorney-client privilege and the expectation of client confidence as the same relate or apply to any such communications belongs to Seller and the same may be controlled by Seller and shall not pass to or be claimed by Buyer or the Company Group. Notwithstanding the foregoing, in the event that a dispute arises between Buyer or the Company Group on the one hand and a third party other than Seller, on the other hand, Buyer or the Company Group may assert the attorney-client privilege to prevent disclosure of confidential communications to such third party.
