Such calculation shall be subject to verification pursuant to Section 2.7(a). Buyer shall then compare the Closing Working Capital to the

Reference Working Capital Amount. If the Reference Working Capital Amount exceeds the amount of Closing Working Capital calculated in accordance with the Working Capital Rules, then the Stock Payment shall be reduced by such amount. If the Closing Working Capital is greater than the Reference Working Capital Amount, then the Stock Payment shall be increased by such amount.

2.5. Net Debt Adjustment.

If the Net Debt is greater than negative $1,800,000, then the Stock Payment shall be increased by an amount equal to sixty-five percent (65%) of the increase in Net Debt, provided that the Stock Payment shall be limited to an amount that, together with all other adjustments pursuant to Section 2.4 and Section 2.6, would result in the delivery of shares of Parent Common Stock, and Parent Preferred Stock issued pursuant to this Agreement and the Plan in an amount such that the number of (i) shares of Parent Common Stock, plus (ii) the aggregate liquidation preference of the Parent Preferred Stock divided by the Closing Share Price, is no greater than 21,000,000. “Net Debt” is an amount equal to fifty percent (50%) of (x) all current assets of Point Lisas Nitrogen Limited (“Point Lisas”) minus (y) all current liabilities of Point Lisas (other than, to avoid double-counting, Indebtedness) minus (z) all Indebtedness of Point Lisas, in each case calculated in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”), applied in a manner consistent with the financial statements of Point Lisas for the period ended on June 30, 2003 as previously provided to Parent.

The sum of such net cash proceeds (excluding any proceeds from the sale of Transferred Subsidiaries or the assets thereof) and the Closing Senior Debt is the “Adjusted Closing Senior Debt.” For avoidance of doubt, material capital assets shall not include any asset that would have been included in Closing Working Capital for purposes of Section 2.4 had such asset not been sold. Such calculation shall be subject to verification pursuant to Section 2.7(a). Buyer shall then compare the Adjusted Closing Senior Debt amount to the Reference Senior Debt Amount. If the Reference Senior Debt Amount exceeds the amount of Adjusted Closing Senior Debt, then the Stock Payment shall be increased by such amount. If the Adjusted Closing Senior Debt is greater than the Reference Senior Debt Amount, then the Stock Payment shall be reduced by such amount. “Closing Senior Debt” means all amounts owed by the Company with respect to the Senior Debt plus the Claims and the Estimated Post Closing Expenses and Disputed Claims.

(a) If based on the calculations delivered by Buyer pursuant to Sections 2.4, 2.5 and 2.6, the Stock Payment exceeds the portion of the Stock Payment delivered to the Distributing Agent for distribution to the Company Creditors pursuant to Section 2.3(b), Buyer shall, within one (1) Business Day of delivering such calculations, deliver or cause the Adjustment Escrow Agent to deliver to the Distributing Agent for distribution to the Company Creditors such excess in Parent Common Stock or Parent Preferred Stock in accordance with Section 2.3(a)(iii).

Parent and Buyer agree to provide the Verifier with all information and materials in its possession as shall be necessary in connection therewith.

(c) by Buyer, if there shall be a breach by the Company of any representation or warranty, or any covenant or agreement contained in this Agreement which would result in a failure of a condition set forth in Section 10.3 and which breach cannot be cured or has not been cured by the earlier of (A) 20 Business Days after the giving of written notice by Buyer to the Company of such breach and (B) the Termination Date (a “Company Breach Termination Event”);

(d) by the Company, if there shall be a breach by Buyer or Parent of any representation or warranty, or any covenant or agreement contained in this Agreement which would result in a failure of a condition set forth in Section 10.2 and which breach cannot be cured or has not been cured by the earlier of (A) 20 Business Days after the giving of written notice by the Company to Buyer and Parent of such breach and (B) Termination Date (a “Buyer Breach Termination Event”);

(f) by either Buyer or the Company, immediately upon an Order becoming final and non-appealable that declares this Agreement, the Deposit Escrow Agreement,

the Holdback Escrow Agreement or the Adjustment Escrow Agreement invalid or unenforceable in any material respect or that prevents the consummation of the transactions contemplated hereby or thereby (a “Termination Order”); provided, however, that neither the Company nor Buyer shall have the right to terminate this Agreement pursuant to this Section 11.2(f) if such party or any of its Affiliates has sought entry of, or has failed to use all commercially reasonable efforts to oppose entry of, such Termination Order;

(g) by Buyer if the Company has not obtained the Order of the Bankruptcy Court contemplated by Section 8.1 hereof approving the Pre-Confirmation Protections within forty-five (45) Business Days after the date hereof; or

(h) by the Company, in order to enter into any agreement concerning or to consummate a Superior Proposal.

(a) If this Agreement is terminated by the Company pursuant to Section 11.2(d) as a result of a Buyer Breach Termination Event, then the Company shall as an exclusive remedy be entitled to retain the Deposit or draw the full amount under the Letter of Credit as liquidated damages and, notwithstanding any provision in this Agreement to the contrary, shall not be entitled to seek any other remedies conferred hereby, or by law or equity upon such party, and none of the Company, its Subsidiaries and Non-Controlled Subsidiaries, Buyer or any of its respective Related Persons shall have any liability or obligation arising under or in connection with this Agreement.

(b) If this Agreement is terminated for any reason other than a Buyer Breach Termination Event: (i) the Deposit, together with any interest accrued thereon less any fees and expenses of the Escrow Agent, shall be returned to Buyer or the Letter of Credit shall be released, as applicable, (ii) this Agreement shall become null and void and have no effect (other than Article 11 and Article 12, which shall survive termination), and (iii) except as provided in this Section 11.3, none of the Company or its Subsidiaries, nor Buyer or any of its respective Related Persons shall have any liability or obligation arising under or in connection with this Agreement.

(c) If this Agreement is terminated by (i) Buyer pursuant to Section 11.2(c) as a result of a Company Breach Termination Event (other than under Section 8.1) resulting from a Material Adverse Effect or by the Company pursuant to Section 11.2(h) in connection with a Superior Proposal, then the Company will promptly pay to Buyer in immediately available funds a cash fee equal to $8,400,000 (the “Break-Up Fee”).

(d) If this Agreement is terminated by Buyer pursuant to Section 11.2(c) as a result of a Company Breach Termination Event (other than Section 8.1), then, subject to Section 11.3(j), the Company will promptly reimburse Buyer for all Transaction Expenses up to $2,000,000. If this Agreement is terminated by the Company pursuant to Section 11.2(h) in connection with a Superior Proposal, then Section 11.3(j), the Company will promptly reimburse Buyer for all Transaction Expenses up to $4,000,000.

(e) Notwithstanding anything in this Agreement to the contrary, in the event the Agreement is terminated pursuant to Section 11.2(b), and at the time of such termination there did not exist a failure by the Company to fulfill its obligations under Section 6.1, then the Company shall have no obligation to pay a Break-Up Fee to Parent or Buyer or reimburse any Transaction Expenses.

(f) In the event the Agreement is terminated by Buyer pursuant to Section 11.2(c) as a result of a failure by the Company to satisfy the condition specified in Section 10.3(c) despite the Company’s commercially reasonable efforts, then the Company shall have no obligation to pay a Break-Up Fee to Parent or Buyer or reimburse any Transaction Expenses.

(g) Notwithstanding anything herein to the contrary, in the event Buyer or Parent shall become obligated to pay or has paid any fees or expenses to any financing source that shall fail to provide such financing for any reason other than the Company’s breach of this Agreement, the Company shall have no obligation hereunder to reimburse Buyer or Parent, and the term “Transaction Expenses” shall not be read to include such fees and/or expenses.

(h) In the event the Closing does not occur and the Company pays the Transaction Expenses pursuant to Section 11.3(d), and the Break-Up Fee pursuant to Section 11.3(c), if applicable, the availability of such remedy shall serve as the exclusive remedy available to Parent and Buyer for breach of this Agreement by the Company and, notwithstanding any provision in this Agreement to the contrary, Buyer and Parent shall not be entitled to seek any other remedies conferred hereby, or by law or equity upon such party, and none of the Company or its Subsidiaries shall have any liability or obligation arising under or in connection with this Agreement.

(i) The Company’s obligation to pay the Break-Up Fee and Transaction Expenses shall survive termination of this Agreement and shall constitute an administrative expense of the Company under section 364(c)(1) of the Bankruptcy Code with priority over any and all administrative expenses of the kind specified in Section 503(b) or 507(b) of the Bankruptcy Code.

(j) For avoidance of doubt, the parties agree that the Company, Buyer and Parent shall have no liability to the others if the Agreement is terminated by Buyer because the Company shall not have obtained an Order approving the Pre-Confirmation Protections from the Bankruptcy Court.

12.1. Successors and Assigns. This Agreement shall inure to the benefit of and shall be binding upon the successors and permitted assigns of the parties hereto. Except as otherwise provided in this Agreement, no party hereto shall assign this Agreement or any rights or obligations hereunder without the prior written consent of the other party hereto, and any such attempted assignment without such prior written consent shall be void and of no force and effect;

provided, however, Buyer may assign its rights (but not its or Parent’s obligations) under this Agreement to a Permitted Assignee and Buyer or any Permitted Assignee may assign its rights hereunder to Buyer’s financing sources for purposes of collateral security. This Agreement shall inure to the benefit of and shall be binding upon the successors and permitted assigns of the parties hereto.

12.2. Governing Law; Jurisdiction. This Agreement shall be construed, performed and enforced in accordance with, and governed by, the Laws of the State of Delaware (without giving effect to the principles of conflicts of Laws thereof), except to the extent that the Laws of such State are superseded by the Bankruptcy Code. For so long as the Company is subject to the jurisdiction of the Bankruptcy Court, the parties hereto irrevocably elect as the sole judicial forum for the adjudication of any matters arising under or in connection with the Agreement, and consent to the exclusive jurisdiction of, the Bankruptcy Court. After the Company is no longer subject to the jurisdiction of the Bankruptcy Court, any legal action or proceeding with respect to this Agreement or the transactions contemplated hereby may be brought in the courts of the State of Delaware sitting in Delaware or of the United States for the State of Delaware, and by execution and delivery of this Agreement, each of the parties consents to the non-exclusive jurisdiction of those courts. Each of the parties irrevocably waives any objection, including any objection to the laying of venue or based on the grounds of forum non conveniens, which it may now or hereafter have to the bringing of any action or proceeding in such jurisdiction in respect of this Agreement or the transactions contemplated hereby.

12.3. Indemnification. Subject to Section 12.4, at the end of the Holdback Period, Buyer will calculate the amount of any actual or reasonably anticipated out-of-pocket losses, Liabilities, obligations, damages, costs and expenses arising or resulting from any breach by the Company of its representations, warranties or covenants in this Agreement and all actions, suits, proceedings, claims, demands, assessments, judgments, costs and expenses, including reasonable attorneys’ fees, incident to the foregoing (individually, a “Post-Closing Loss” and collectively, “Post-Closing Losses”). Within five (5) Business Days after the last day of the Holdback Period, Buyer shall (i) provide to the OCC a detailed schedule of such Post-Closing Losses and a description of the facts and circumstances pursuant to which Buyer asserts that it is entitled to recourse from the Holdback Amount pursuant to this Agreement and (ii) direct the Holdback Escrow Agent to release to Distribution Agent for distribution to the Company Creditors the Parent Common Stock and Parent Preferred Stock (or redemption proceeds) which is in excess of the amount which would have an aggregate value, determined in the manner specified in Section 2.3(a)(iii), equal to such estimated Post-Closing Losses based on the liquidation preference of the Parent Preferred Stock and the Closing Share Price of Parent Common Stock. Buyer shall also provide any reasonable supporting documentation requested by the OCC to facilitate its review of such schedule. The OCC shall have twenty (20) business days to review such schedule, description and supporting documentation and provide written notice of any objections to any Post-Closing Loss (or the basis therefore or calculation thereof) set forth therein. If Buyer and the OCC cannot agree on the amount of any such Post-Closing Loss, the calculation thereof shall be subject to arbitration in accordance with the Arbitration Procedures. Within five (5) Business Days of such determination of the Post-Closing Losses, Buyer shall advise the Holdback Escrow Agent of the amount of Post-Closing Losses and the Holdback Escrow Agent shall release to Buyer such amount of Parent Preferred Stock (or redemption proceeds), and to the extent necessary, Parent Common Stock in the manner specified in

Section 2.3(a)(iii), with an aggregate value equal to such Post-Closing Losses based on the liquidation preference of the Parent Preferred Stock and the Closing Share Price of Parent Common Stock. The remainder of the Holdback Amount, if any, shall simultaneously be released to the Distributing Agent for the Company Creditors in accordance with the Holdback Escrow Agreement.

12.4. Limitation on Indemnification. Buyer shall not claim any Post-Closing Losses pursuant to Section 12.3 unless and to the extent the aggregate amount of such Post-Closing Losses exceeds $2,000,000 in the aggregate; provided that the foregoing limitation shall not apply to any Post-Closing Loss arising from, or related to, a breach of any covenant of the Company. Whether or not the Closing shall occur, other than against the Holdback Amount pursuant to Section 12.3 hereof, neither Parent nor Buyer shall have any recourse against any stockholder, creditor, employee, agent, officer or director of the Company or against the OCC or its members or agents. In the event the Closing shall occur, Buyer’s sole and exclusive remedy for any breach of this Agreement shall be by recourse to the Holdback Amount pursuant to Section 12.3.

12.5. Notification of Certain Matters. Each of the Company and Buyer and Parent shall give reasonably prompt notice to the other party of (i) the occurrence or non-occurrence, of any event the occurrence or non-occurrence, of which would be likely to cause (x) any representation or warranty contained in this Agreement to be untrue or inaccurate, in any material respect, or (y) any covenant, condition or agreement contained in this Agreement not be complied with or satisfied, in any material respect; and (ii) any failure or inability of such party to comply, in any material respect, with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder.

12.6. Mutual Drafting. This Agreement is the result of the joint efforts of Buyer, Parent and the Company, and each provision hereof has been subject to the mutual consultation, negotiation and agreement of the parties and there is to be no construction against either party based on any presumption of that party’s involvement in the drafting thereof.

12.7. Expenses. Except as otherwise provided herein, each of the parties hereto shall pay its own expenses in connection with this Agreement and the transactions contemplated hereby, including any legal and accounting fees, whether or not the transactions contemplated hereby are consummated.

12.8. Broker’s and Finder’s Fees. Each of the parties represents and warrants that no broker or finder in connection with any of the transactions contemplated by this Agreement shall be entitled to receive any fees or expenses from any other party, the fees and expenses of whom shall, as between the parties hereto, be the responsibility of the other party.

12.9. Further Assurances. Parent, Buyer and the Company shall cooperate in effecting the closing of the transactions contemplated by this Agreement. In furtherance of the foregoing, upon the Buyer or Parent’s request, the Company shall, at the Closing, execute and deliver such documents as are necessary or desirable to effect the transfer of one or more assets of the Company directly to Buyer, Parent or any of Parent’s subsidiaries; provided, however, that such transfers shall not result in any adjustments to the Purchase Price, whether under Sections 2.4, 2.5, 2.6 or otherwise.

12.10. Severability. In the event that any part of this Agreement is declared by any court or other judicial or administrative body to be null, void or unenforceable, said provision shall survive to the extent it is not so declared, and all of the other provisions of this Agreement shall remain in full force and effect only if, after excluding the portion deemed to be unenforceable, the remaining terms shall provide for the consummation of the transactions contemplated hereby in substantially the same manner as originally set forth at the later of the date this Agreement was executed or last amended.

12.11. Notices. All notices, requests, demands and other communications under this Agreement shall be in writing and shall be deemed to have been duly given: (a) on the date of service if served personally on the party to whom notice is to be given; (b) on the day of transmission if sent via facsimile transmission to the facsimile number given below, and telephonic confirmation of receipt is obtained promptly after completion of transmission; (c) on the day after delivery to Federal Express or similar overnight courier or the Express Mail service maintained by the United States Postal Service; or (d) on the fifth day after mailing, if mailed to the party to whom notice is to be given, by first class mail, registered or certified, postage prepaid and properly addressed, to the party as follows:

A copy of each notice or other communication delivered under this Agreement, shall be provided to the OCC by the party giving such notice to the following address:

Any party may change its address for the purpose of this Section 12.11 by giving the other party written notice of its new address in the manner set forth above.

12.12. Amendments; Waivers. This Agreement may be amended or modified, and any of the terms, covenants, representations, warranties or conditions hereof may be waived, only by a written instrument executed by the parties hereto, or in the case of a waiver, by the party waiving compliance. Any waiver by any party of any condition, or of the breach of any provision, term, covenant, representation or warranty contained in this Agreement, in any one or more instances, shall not be deemed to be nor construed as a furthering or continuing waiver of any such condition, or of the breach of any other provision, term, covenant, representation or warranty of this Agreement. Notwithstanding the foregoing, no amendment of any provision and no waiver by the Company of any provision shall be effective without the consent of the OCC.

12.13. Public Announcements. No party shall make any press release or public announcement (including announcements to employees, customers or suppliers) concerning the transactions contemplated by this Agreement without the prior written approval of the other parties, unless a press release or public announcement is required by Law or Order of the Bankruptcy Court. If any such announcement or other disclosure is required by Law or Order of the Bankruptcy Court, the disclosing party shall give the nondisclosing party or parties prior notice of, and an opportunity to comment on, the proposed disclosure. The parties acknowledge that the Company shall file this Agreement and other related pleadings with the Bankruptcy Court in connection with obtaining the Confirmation Order and the Order approving the Pre-Confirmation Protections.

12.14. Employee and Customer Announcements. The Company and Buyer shall agree on a communications plan prior to any announcement of this Agreement to any of the Company’s customers or employees (other than those employees involved in the sale process).

12.15. Entire Agreement. This Agreement, the Confidentiality Agreement, the Deposit Escrow Agreement, the Holdback Escrow Agreement and the Adjustment Escrow Agreement contain the entire understanding among the parties hereto with respect to the transactions contemplated hereby and supersede and replace all prior and contemporaneous agreements and understandings, oral or written, with regard to such transactions. All schedules and exhibits hereto and any documents and instruments delivered pursuant to any provision hereof are expressly made a part of this Agreement as fully as though completely set forth herein.

12.16. Parties in Interest. Nothing in this Agreement is intended to confer any rights or remedies under or by reason of this Agreement on any Persons other than the Company, on the one hand, and Buyer and Parent on the other hand, and their respective successors and permitted assigns and in case of any provision naming the OCC or the Company Creditors, the OCC and the members thereof. Nothing in this Agreement is intended to relieve or discharge the obligations or liability of any third Persons to the Company, Buyer or Parent. No provision of this Agreement shall give any third Persons any right of subrogation or action over or against the Company, Buyer or Parent. Without limiting the foregoing, the parties agree that the OCC and its members are third party beneficiaries to Sections 2.1, 2.3 through 2.7, 3.2, 3.3, 5.1 through 5.12, 7.1 through 7.8, 8.3, 8.4, 8.12, 11.1 through 11.3, 12.3, 12.4, 12.11, 12.12 and this Section 12.16.

12.17. Headings. The article and section headings in this Agreement are for reference purposes only and shall not affect the meaning or interpretation of this Agreement.

12.18. Construction. Unless the context of this Agreement otherwise requires, (i) words of any gender include the other gender, (ii) words using the singular or plural number also include the plural or singular number, respectively, (iii) the terms “hereof,” “herein,” “hereby,” and derivative or similar words refer to this entire Agreement as a whole and not to any other particular Article, Section or other subdivision, (iv) the words “include,” “includes” and “including” shall be deemed to be followed by the phrase “without limitation,” (v) “shall,” “will,” or “agrees” are mandatory, and “may” is permissive, and (vi) “or” is not exclusive.

12.19. Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which shall constitute the same agreement.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their respective officers thereunto duly authorized as of the date first above written.
