The aggregate amount payable by Buyer to Seller in respect of the Shares (the “Purchase Consideration”) shall consist of cash (the “Aggregate Cash Consideration”) in an aggregate amount equal to the sum of (a) $50,000,000, plus (b) the Estimated Working Capital subject to adjustment as provided in Section 2.6.

Section 2.5. Deposit. Buyer shall engage an escrow agent and Buyer and Seller shall enter into the Escrow Agreement as soon as practicable after the date of this Agreement (and in any case no later than November 11, 2005). Buyer shall deposit $2,500,000 (the “Deposit”) in immediately available funds with the escrow agent within two (2) Business Days after the date the Escrow Agreement is fully executed. The Deposit will be held pursuant to the terms of the Escrow Agreement, such Deposit to be applied towards the Aggregate Cash Consideration or otherwise applied or paid in the manner provided for by Article VIII.

Section 2.6. Adjustment of Aggregate Cash Consideration.

(a) Not later than 10 Business Days before the Closing Date, Seller will provide Buyer with Seller’s good faith estimate of the Company’s Closing Working Capital, based upon the accounting books and records of the Company (the “Estimated Working Capital”), and all underlying documentation supporting the Estimated Working Capital. The determination of the Estimated Working Capital will be binding on Seller and Buyer for purposes of this Section 2.6(a) and will be used to determine the amount of the Aggregate Cash Consideration payable to Seller at the Closing. The Estimated Working Capital Amount must be equal to or greater than zero. In the event that the Estimated Working Capital Amount is less than zero, Seller shall contribute an amount of cash to the Company necessary to cause the Estimated Working Capital Amount to equal zero.

(b) As promptly as practicable, but no later than 45 days after the Closing Date, Seller shall cause to be prepared and delivered to Buyer the Closing Statement (as defined below) and a certificate based on such Closing Statement setting forth Seller’s calculation of Closing Working Capital. The closing statement (the “Closing Statement”) shall present the Net Working Capital as of the end of business on the Closing Date (“Closing Working Capital”).

“Net Working Capital” means the amount equal to the Company’s cash, plus inventory (including, without limitation, supplies, parts, unamortized catalyst expenditures and recovered precious metals), plus trade receivables (other than trade receivables owing from Seller or its Affiliates), minus the accounts payable minus accrued liabilities (excluding all current and deferred Taxes based on the Company’s income) of the Company, in each case as determined in accordance with the Applicable Accounting Principles. A sample calculation of Net Working Capital is attached hereto as Annex A.

(c) If Buyer disagrees with Seller’s calculation of Closing Working Capital delivered pursuant to Section 2.6(b), Buyer may, within 30 days after delivery of the Closing Statement, deliver a notice to Seller disagreeing with such calculation and setting forth Buyer’s calculation of such amount. Any such notice of disagreement shall (i) specify those items or amounts as to which Buyer disagrees, and Buyer shall be deemed to have agreed with all other items and amounts contained in the Closing Statement and the calculation of Closing Working Capital delivered pursuant to Section 2.6(b) and (ii) only include disagreements based on mathematical errors or Seller’s failure to follow Applicable Accounting Principles in its calculation of Closing Working Capital.

(d) If a notice of disagreement shall be duly delivered pursuant to Section 2.6(c), Buyer and Seller shall, during the 15 days following such delivery, use their commercially reasonable efforts to reach agreement on the disputed items or amounts in order to determine the amount of Closing Working Capital, which amount shall not be less than the amount thereof shown in Seller’s calculation delivered pursuant to Section 2.6(b) nor more than the amount thereof shown in Buyer’s calculation delivered pursuant to Section 2.6(c). If during such period, Buyer and Seller are unable to reach such agreement, they shall promptly thereafter cause PricewaterhouseCoopers (the “Accounting Referee”) to review this Agreement and the disputed items or amounts for the purpose of calculating Closing Working Capital. In making such calculation, the Accounting Referee shall consider only (i) those items or amounts in the Closing Statement and Buyer’s calculation of Closing Working Capital as to which Buyer has disagreed and (ii) disagreements based on mathematical errors or Seller’s failure to follow Applicable Accounting Principles in its calculation of Closing Working Capital. The Accounting Referee shall deliver to Buyer and Seller, as promptly as practicable (but in any case no later than 30 days from the date of engagement of the Accounting Referee), a report setting forth such calculation. Such report shall be final and binding upon Buyer and Seller. The cost of such review and report shall be borne equally by Buyer and Seller.

(e) Buyer and Seller shall, and shall cause their respective representatives, and Buyer shall cause the Company, to cooperate and assist in the preparation of the Closing Statement and the calculation of Closing Working Capital and in the conduct of the review referred to in this Section 2.6, including, without limitation, the making available to the extent necessary of books, records, work papers and personnel.

(f) If Final Working Capital exceeds Estimated Working Capital, Buyer shall pay to Seller, in the manner as provided in Section 2.6(g), the amount by which Final Working Capital so exceeds Estimated Working Capital as an adjustment to the Purchase Consideration and, if Estimated Working Capital exceeds Final Working Capital, Seller shall pay to Buyer the amount by which Estimated Working Capital so exceeds Final Working Capital as an adjustment to the Purchase Consideration.

“Final Working Capital” means Closing Working Capital (i) as shown in Buyer’s calculation delivered pursuant to Section 2.6(b) if no notice of disagreement with respect thereto is duly delivered pursuant to Section 2.6(c); or (ii) if such a notice of disagreement is delivered, (A) as agreed by Buyer and Seller pursuant to Section 2.6(d) or (B) in the absence of such agreement, as shown in the Accounting Referee’s calculation delivered pursuant to Section 2.6(d).

(g) Any payment pursuant to Section 2.6(f) shall be made at a mutually convenient time and place within 3 Business Days after Final Working Capital has been determined by wire transfer by Buyer or Seller, as the case may be, of immediately available funds to the account of such other party as may be designated in writing by such other party.

Section 5.7. Tax Matters.

(a) 338(h)(10) Election. Seller and Buyer shall jointly make (or cause to be made), and will take any and all action necessary to effect, a timely election under section 338(h)(10) of the Code (and any comparable elections under state and local income Tax law) with respect to the Company (the “Election”). Buyer and Seller shall execute and submit Internal Revenue Service Form 8023 at Closing pursuant to Section 6.2 of this Agreement.

	(i) Within 120 days following the Closing Date, the Seller shall prepare and deliver to the Buyer Internal Revenue Service Form 8883, and any similar forms required by state or local law (together with Internal Revenue Service Form 8023 and any equivalent state or local law forms, the “Forms”), together with a proposed allocation of the consideration deemed paid for the assets of the Company. The Forms shall be prepared in accordance with Section 338 of the Code and any applicable Treasury Regulations (or, if applicable, comparable provisions of state and local income tax law). The Buyer shall have 30 days following the receipt of the Forms from the Seller to notify the Seller in writing whether or not the Buyer accepts the Forms as prepared by the Seller. If the Buyer notifies the Seller that it does not accept any of the Forms, it shall set out in reasonable detail in the written notice its reasons for non-acceptance and specify the adjustments, which, in its opinion, should be made. The Seller and the Buyer shall use all reasonable efforts to reach agreement on the adjustments, if any, to be made to the Forms. If the Seller and the Buyer do not reach agreement within 25 days after the Seller receives the Buyer’s notice of non-acceptance, the matter shall be referred to and determined by the Accounting Referee as promptly as feasible and the determination shall be binding on both the Buyer and the Seller.

	(ii) The Forms, as prepared and agreed to pursuant to this Section 5.7, shall be final, conclusive and binding on the Buyer and the Seller. Neither the Seller nor the Buyer shall, or shall permit any of their Affiliates to, take any action to modify any of the Forms or reports (including any corrections, amendments, or supplements thereto) that are required for the making of the Election after its execution or to modify or revoke the Election following the filing of the Forms without the prior written consent of the other party. Each of the Seller and the Buyer will be responsible for timely filing Form 8883 in a manner consistent with the Forms. Each of the Buyer and Seller shall be responsible for filing all Forms required by any state or local jurisdiction.

	(iii) In the event that any of the Forms is disputed by any Governmental Authority, the party receiving notice of such dispute shall promptly notify and consult with the other party hereto concerning resolution of such dispute.

(b) Pre-Closing Taxes; Straddle Periods. Seller shall be responsible for paying “Pre-Closing Taxes,” which shall be defined as all Taxes due with respect to any Tax period that ends on or before the Closing Date and Taxes attributable to the Pre-Closing Tax Period of a Straddle Period, as determined in accordance with this Section 5.7(b), except to the extent that such Taxes are reflected in Net Working Capital. Unless prohibited by applicable law, Buyer, Seller and the Company shall cause the taxable year of the Company to close on the Closing Date. 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 based on or measured by income, receipts or expenditures of the Company for the Pre-Closing Tax Period shall be determined based on an interim closing of the books as of the close of business on the Closing Date and the amount of other Taxes of the Company for a Straddle

Period which relate to the Pre-Closing Tax Period shall be deemed to be the amount of such Tax for the entire taxable period in which the Straddle Period occurs multiplied by a fraction the numerator of which is the number of days in the Taxable period ending on the Closing Date and the denominator of which is the total number of days in the Straddle Period. For avoidance of doubt, any Taxes realized on or before the Closing as a result of the Election (the “338 Taxes”) or other Taxes on income or gain realized on or before the Closing as a result of the Company’s departure from the Group shall be Pre-Closing Taxes.

(c) Preparation of Pre-Closing Period Returns. The Company shall continue to be included for all taxable periods ending on or before the Closing in the consolidated federal income Tax Return for the affiliated group of which Seller is the common parent (the “Group”) and any required state or local consolidated, combined or unitary income or franchise Tax Returns that include the Company (all such Tax Returns including taxable periods of the Company ending on or before the Closing Date are hereinafter referred to as “Pre-Closing Consolidated Returns”). Seller shall prepare and file all Pre-Closing Consolidated Returns and all other Tax Returns for a period that ends on or before the Closing Date (collectively, “Pre-Closing Period Returns”). Seller shall pay all Taxes and be entitled to all refunds and credits attributable to all Pre-Closing Period Returns.

(d) Preparation of Straddle Period Returns. Buyer shall prepare or cause to be prepared and file or cause to be filed all Returns of the Company for any Straddle Period (each a “Straddle Period Return”). Buyer shall provide a copy of each such Straddle Period Return to Seller for its approval not later than 45 days prior to the deadline for filing each such Tax Return. Concurrently with the provision to the Seller of any Straddle Period Return (including any draft Straddle Period Return), Buyer shall provide a computation of the Pre-Closing Taxes reflected in any such Straddle Period Return (such computation, the “Statement”). If Seller disagrees with the allocation in the Statement or with such Straddle Period Return, Seller shall notify Buyer in writing of such disagreement within 15 days of receipt of the Statement, and Seller and Buyer shall consult and attempt to resolve in good faith the disagreement. In the event that Seller and Buyer are unable to resolve the disagreement within 10 days, Seller and Buyer shall submit the matter to the Accounting Referee to resolve the dispute as promptly as possible.

(e) Tax Cooperation. After the Closing Date, Seller shall submit to Buyer blank tax return workpaper packages reasonably necessary for Seller to prepare any Pre-Closing Consolidated Returns. Buyer shall prepare or cause to be prepared completely and accurately all information that Seller shall reasonably request in such workpaper packages and shall submit to Seller such packages within the later of 60 days after Buyer’s receipt thereof or 45 days after the close of the taxable period to which a workpaper package relates. Each party shall cooperate with the other in connection with any Tax filing, investigation, audit or other proceeding. Buyer and Seller shall (i) preserve and cause to be preserved all information, returns, books, records and documents relating to any liabilities for Taxes of the Company with respect to a taxable period until the later of sixty 60 days after the expiration of all applicable statutes of limitation and extensions thereof, or the conclusion of all litigation with respect to Taxes for such period and (ii) give reasonable written notice to the other party prior to transferring, destroying or discarding any such information, returns, books, records or documents and, if the other party so requests, allow party to take possession of such information, returns, books, records or documents. Buyer shall make available to Seller (and to Seller’s accountants and attorneys) any and all books and records and other documents and information in its possession or control related to the Company reasonably requested by Seller to prepare Pre-Closing Consolidated Returns or to deal with audits related to pre-Closing periods.

(f) Carrybacks. To the extent permitted by law, Buyer shall not, and shall cause the Company or any of its Subsidiaries not to, carry back any tax attribute to a period ending on or before the Closing Date.

(g) Buyer shall not cause or permit Company to take any extraordinary action on the Closing Date (other than the Election), and if it does, Buyer shall be responsible for any Tax costs resulting from such action.

Section 5.8. Employee Matters.

(a) At the Closing, Buyer shall cause the Company to offer continued employment to all employees employed by the Company immediately prior to the Closing Date (collectively, “Employees”), provided that subject to the terms of any applicable collective bargaining agreement the Company shall have the same right to terminate the employment of any Employee following the Closing and to adopt such compensation, incentive and benefit programs as it shall determine in its sole judgment as it has on the date hereof.

(b) From and after the Closing Date, Buyer shall maintain for all Employees credit for any service with the Company earned prior to the Closing Date:

	(i)	for eligibility and vesting (but not benefit accrual) purposes and

	(ii)	for purposes of vacation accrual and severance benefits

under any employee benefit plan, program or arrangement that is established or maintained by the Company on or after the Closing Date (the “Buyer Benefit Plans”). In addition, Buyer shall (i) waive all pre-existing condition exclusion and actively-at-work requirements and similar limitations, eligibility waiting periods and evidence of insurability requirements under any Buyer Benefit Plans to the extent required by the Health Insurance Portability and Accountability Act of 1996, and (ii) take into account any covered expenses incurred on or before the Closing Date by any Employee (or covered dependent thereof) for purposes of satisfying applicable deductible provisions after the Closing Date under any applicable Buyer Benefit Plan. Buyer will, or will cause the Company to, maintain Buyer Benefit Plans for the benefit of Non-Union Employees and their dependents that are, in the aggregate, substantially similar to the employee benefit plans, programs or arrangements that the Buyer provides to its similarly situated employees, provided that, for the avoidance of doubt, collective bargaining agreements are deemed to not be substantially similar plans, programs or arrangements for the benefit of Non-Union Employees and their dependants. Subject to Section 5.8(h), Buyer’s health benefit plan shall be responsible for all benefits incurred on and after the Closing Date by eligible Employees and their covered dependents. Seller’s health plan shall be responsible for all benefits incurred prior to the Closing Date by eligible Employees and their covered dependants as determined under the terms of Seller’s plan. Notwithstanding the foregoing, costs and expenses (be they administrative, direct payment of expenses or otherwise) of Seller under or in connection with the operation of the preceding sentence for benefits rendered on or after the Closing Date for eligible Employees and their covered dependents as of the Closing Date shall be for the account of Buyer, which shall reimburse Seller therefor up to an amount no greater than $325,000. Such reimbursement shall occur within twenty (20) days after receipt of a reasonably detailed notice thereof, provided that the date that the underlying benefits were rendered is reasonably ascertainable.

(c) Notwithstanding any limitation in Sections 5.8(a) or 5.8(b) above, Buyer shall, and shall cause the Company to, honor any collective bargaining agreements, including without limitation any amendments, addenda or memoranda of understanding relating or entered into in connection therewith, by which the Company is bound on the date hereof, with such changes therein as may be agreed to in the Ordinary Course of Business, or with Buyer’s consent (which shall not be unreasonably withheld), between the date hereof and Closing. Employees whose terms and conditions of employment are subject to any such collective bargaining agreements are hereinafter referred to as “Union Employees.” All other Employees are referred to as “Non-Union Employees.”

(d) 401(k)/Savings Plans.

Non-Union Employees

	(i) As soon as practicable, but in any event within 90 days, following Closing, Buyer will establish, or designate, a savings plan qualified under Code Section 401(a) and including a cash or deferred feature under Code Section 401(k) and a related trust thereunder which shall be exempt under Code Section 501(a) (collectively “Buyer’s Savings Plan”) for the benefit of Non-Union Employees. Buyer’s Savings Plan may be sponsored by Buyer or any other entity controlled, within the meaning of Code Section 414, by Buyer.

	(ii) Buyer shall allow Non-Union Employees to participate in the Buyer’s Savings Plan on terms and conditions substantially similar to its similarly situated employees, with service credit as provided under Section 5.8(b) above.

	(iii) All Non-Union Employees will fully vest in their accounts held under Seller’s savings plan qualified under Code Section 401(a) and including a cash or deferred feature under Code Section 401(k) (“Seller’s 401(k) Plan”) as of the Closing Date. Buyer will cause the Buyer’s Savings Plan to accept the rollover, by direct or indirect rollover, as selected by each Non-Union Employee, of that portion of the Non-Union Employee’s accounts in Seller’s 401(k) Plan that constitutes an “eligible rollover distribution” as that term is defined by Section 402(c)(4) of the Code, provided that at the time a Non-Union Employee elects such a rollover that Non-Union Employee is employed by the Buyer or an employer under Buyer’s control within the meaning of Section 414 of the Code. Any such rollover will be effected in cash and, as applicable, any notes evidencing loans from the Seller’s 401(k) Plan to the Non-Union Employee electing such rollover. Buyer and Seller will, and will cause the trustees of their respective 401(k) plans to, cooperate with each other with respect to the rollover of the eligible rollover distribution portions of the Non-Union Employees’ account balances in the Seller’s 401(k) Plan to the Buyer’s Savings Plan.

	Union Employees

	(i) Buyer will, or will cause the Company to, assume and continue in effect the 401(k) plan maintained for the benefit of Union Employees on the date hereof, in accordance with the terms of the applicable plan documents and collective bargaining agreement.

(e) Vacation and Sick Leave. Buyer will, and will cause the Company to honor all vacation pay and sick leave accrued by any Employee of the Company as of the Closing Date to the extent reflected in the Closing Working Capital.

(f) Severance Benefits. Buyer will, and will cause the Company to pay severance benefits to any Employee terminated with the one year period following closing, that are at least equal to the severance benefits to which such Employee would be entitled under the terms of the applicable severance plan on the date hereof.

(g) WARN Act. The Buyer shall be solely responsible for any Claim arising under the Worker Adjustment Retraining Notification Act, or any equivalent state or local statute or ordinance requiring the provision of notices to Employees affected by a plant closing, mass layoff, or the like (collectively, the “WARN Act”), relating to or arising from the failure to retain in employment, or the termination or layoff of any Employees or any other employment decision made by Buyer on or after the Closing Date.

(h) COBRA and Disability Benefits. Following the Closing Date, Seller shall continue to maintain a group health plan and disability plans. Therefore, Seller agrees and covenants that it shall be responsible for providing (i) continuing short-term and long-term disability benefits under the terms of its plans for any employee or former employee of the Company who is entitled to payments of such benefits as of the Closing Date and (ii) continuation coverage as required by COBRA to those employees of the Company and any other qualified beneficiaries under COBRA with respect to such employees who have a COBRA qualifying event prior to or as of the Closing Date. Notwithstanding the foregoing sentence, all costs and expenses (be they administrative, direct payment of expenses or otherwise) incurred by Seller under or in connection with the provision of short-term disability benefits pursuant to the operation of this Section 5.8(h) on and after the Closing Date to eligible Employees entitled to short-term disability payments prior to the Closing Date shall be for the account of Buyer, which shall reimburse Seller therefor up to an amount no greater than $325,000. Such reimbursement shall occur within twenty (20) days after receipt of a reasonably detailed notice thereof. Seller shall indemnify and hold Buyer and the Company harmless from any and all damages, liabilities, claims or expenses incurred by Buyer and the Company as a result of the failure of Seller to comply with the terms of its disability plans or any of the requirements of COBRA, including applicable notice requirements.

Section 5.9. Termination of Affiliate Relations; Indebtedness; Release of Liens.

(d) Payment in full of any amount due under Section 7.2(a)(iii) shall be made to the Buyer in immediately available funds at least five Business Days before the date for payment of the Taxes to which such payment relates is due. The Tax indemnities contained in Section 7.2(a)(iii) shall not be subject to any threshold or other limitations contained in this Agreement.

Section 7.3. Method of Asserting Claims, Etc. The obligations and Liabilities of any party hereto against which indemnification is sought hereunder with respect to claims resulting from the assertion of liability by third parties shall be subject to this Section 7.3.

(a) Promptly after receipt by any Indemnified Party of notice of any demand or claim or the commencement of any action, proceeding or investigation (an “Asserted Liability”) that could reasonably be expected to result in Losses, the Indemnified Party shall promptly give written notice thereof (a “Claims Notice”) to the party obligated to provide indemnification pursuant to Section 7.2(a) or Section 7.2(b). Each Claims Notice shall describe the Asserted Liability in reasonable detail and shall, to the extent reasonably possible, indicate the amount (estimated, if necessary) of the Losses that have been or may be suffered by the Indemnified Party. The rights of any Indemnified Party to be indemnified hereunder shall not be adversely affected by its failure to give, or its failure to timely give, a Claims Notice with respect thereto unless, and if so, only to the extent that, the Indemnifying Party is prejudiced thereby.

(b) The Indemnifying Party shall have the right, exercisable by written notice to the Indemnified Party within 30 days of receipt of a Claims Notice from the Indemnified Party to assume the defense of such Asserted Liability, using counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party. If the Indemnifying Party elects not to defend against, negotiate or settle with any Asserted Liability which relates to any Losses indemnified against hereunder, fails to notify the Indemnified Party of its election as herein provided or contests its obligation to indemnify the Indemnified Party for such Losses under this Agreement, the Indemnified Party may defend against, negotiate, settle or otherwise deal with such Asserted Liability. If the Indemnified Party defends any Asserted Liability, then the Indemnifying Party shall reimburse the Indemnified Party for the Losses of defending such Asserted Liability upon submission of periodic bills. If the Indemnifying Party shall assume the defense of any Asserted Liability, the Indemnified Party may participate, at his or its own expense, in the defense of such Asserted Liability; provided, however, that such Indemnified Party shall be entitled to participate in any such defense with separate counsel at the expense of the Indemnifying Party if (i) so requested by the Indemnifying Party to participate or (ii) in the written opinion of counsel to the Indemnified Party, a conflict or potential conflict exists between the Indemnified Party and the Indemnifying Party that would make such separate representation required under applicable standards of professional responsibility; and provided, further, that the Indemnifying Party shall not be required to pay for more than one such counsel for all indemnified parties in connection therewith. The parties hereto agree to cooperate fully with each other in connection with the defense, negotiation or settlement of any such Asserted Liability. Subject to the foregoing, if the Indemnifying Party elects to compromise or defend such Asserted Liability, the Indemnified Party shall, subject to clause (c) below, cooperate, at the expense of the Indemnifying Party, in the compromise of, or defense against, such Asserted Liability. If the Indemnifying Party chooses to defend any claim, the Indemnified Party shall, make available to the Indemnifying Party any books, records or other documents within its control, and the reasonable assistance of its employees, for which the Indemnifying Party shall be obliged to reimburse the Indemnified Party the reasonable out-of-pocket expenses of making them available.

(c) If any Indemnifying Party has assumed the defense of an Asserted Liability in accordance with the terms hereof, he, she or it shall have the right to consent to the entry of judgment with respect to, or otherwise settle such Asserted Liability without the consent of the Indemnified Party if (i) the settlement involves solely monetary damages, (ii) the Indemnifying Party expressly agrees in writing to the Indemnified Party that, as between the two, the Indemnifying Party is solely obligated to satisfy and discharge the claim and (iii) the Indemnified Party receives an unconditional release of liability. If the foregoing conditions are not satisfied, the Indemnifying Party shall have the right to consent to the entry of judgment with respect to, or otherwise settle such Asserted Liability only upon receipt of the written consent of the Indemnified Party, which consent shall not be unreasonably withheld. If the Indemnified Party does not give such consent, the Indemnifying Party shall resume the diligent defense of the Asserted Liability. Regardless of whether the Indemnifying Party elects to assume the defense of the Asserted Liability in accordance with the terms hereof, the Indemnified Party shall not admit any liability with respect to, consent to the entry of judgment with respect to, or otherwise settle such Asserted Liability without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld or delayed.

(d) After any final decision, judgment or award shall have been rendered by a Governmental Authority of competent jurisdiction and the expiration of the time in which to appeal therefrom, or a settlement shall have been consummated, or the Indemnified Party and the Indemnifying Party shall have arrived at a mutually binding agreement with respect to an Asserted Liability hereunder, the Indemnified Party shall forward to the Indemnifying Party notice of any sums due and owing by the Indemnifying Party pursuant to this Agreement with respect to such matter and the Indemnifying Party shall be required to pay all of the sums so due and owing to the Indemnified Party by wire transfer of immediately available funds within 10 Business Days after the date of such notice.

Section 7.4. Environmental Procedures. Notwithstanding any other provisions contained in this Agreement, Seller shall have the right to direct, manage and control, and take such actions as are reasonably necessary in connection with, any Remediation or defense or other resolution of any claim, event or condition subject to indemnification under or arising from the breaches of Seller’s representations and warranties set forth in under Section 3.18, and Buyer shall provide Seller with access to the Company property reasonably necessary for Seller to exercise their rights under this Section 7.4. Seller’s obligations to indemnify for any Environmental Liability pursuant to this Article VII or to conduct any Remediation shall be deemed satisfied so long as the remedy (i) complies with the minimum and least stringent standards enforceable under applicable Environmental Laws, and (ii) is approved or authorized by Governmental Authorities with jurisdiction over such matters, where such approval or authorization is required by applicable Environmental Laws (the “Remediation Standard”). Seller may use the most commercially reasonable and cost-effective method of achieving the Remediation Standard, including the use of commercial, industrial and/or other forms of non-residential cleanup criteria and the use of environmental land use restrictions or similar institutional controls. Buyer agrees that, if such environmental land use restrictions or similar institutional controls are approved or authorized by Governmental Authorities or Environmental Laws, as applicable, Buyer will execute any required documents and will cooperate with Seller in the recording, on the applicable land records, of such environmental land use restrictions or similar controls; provided, however, such land use restrictions or similar institutional controls do not render the Company Properties unsuitable for use as such Company Properties were used immediately prior to and up to the Closing.

Section 7.5. Indemnification Amounts/Seller. Except for Losses arising from breach of Sections 3.2, 3.3, 3.15 and 3.22, Seller shall not have liability for Seller’s breach of representations and warranties under Section 7.2(a)(i) and for breach of any of the Interim Covenants until the aggregate amount of Buyer’s Losses attributable to indemnification claims under such section exceeds $625,000 (the “Basket Amount”); provided, however, that Seller shall be liable only for the amount by which all Losses exceed the Basket Amount; provided, further, that no individual claim for a breach of a representation or warranty under Section 7.2(a)(i) or a breach of any of the Interim Covenants may be made under Section 7.2 unless such claim is in an amount of $25,000 or greater.

The maximum liability of Seller for Losses as a result of breaches of representations and warranties under Section 7.2(a)(i) and for breach of any of the Interim Covenants shall not exceed $6,125,000; provided that this limitation shall not apply to Losses arising from a breach of the representations made in Sections 3.2, 3.3, 3.15 and 3.22 and will not apply to breaches of any covenant or agreement (other than the Interim Covenants), including any covenant or agreement in Article II or V (other than the Interim Covenants).

Section 7.6. Indemnification Amounts/Buyer. Except for Losses arising from breach of Sections 4.1, 4.2 and 4.4, Buyer shall not have liability for Buyer’s breach of representations and warranties under Section 7.2(b)(i) and for breach of any of the Interim Covenants until the aggregate amount of Seller’s Losses attributable to indemnification claims under such section exceeds the Basket Amount; provided, however, that the Buyer shall be liable only for the amount by which all Losses exceed the Basket Amount.

Section 7.7. Losses Net of Insurance, Etc. The amount of any Loss for which indemnification is provided under Section 7.2 shall be net of (i) any amounts recovered by the Indemnified Party pursuant to any indemnification by or indemnification agreement with any third party, (ii) any insurance proceeds or other cash receipts or sources of reimbursement actually recovered in respect of such Loss (each source named in clauses (i) and (ii), a “Collateral Source”), (iii) an amount equal to the actual Tax benefit realized with respect to such Loss and (iv) any specific accruals or reserves (or overstatement of liabilities in respect of actual liability) included in the Closing Statement. Subject to the foregoing, the parties shall take and shall cause their Affiliates to take all commercially reasonable steps to (i) mitigate any Loss upon becoming aware of any event that would reasonably be expected to, or does, give rise thereto and (ii) seek recovery from all Collateral Sources. If the amount to be netted hereunder from any payment required under Section 7.2 is determined after payment by the Indemnifying Party of any amount otherwise required to be paid to an Indemnified Party pursuant to this Article VII, the Indemnified Party shall repay to the Indemnifying Party, promptly after such determination, any amount that the Indemnifying Party would not have had to pay pursuant to this Article VII had such determination been made at the time of such payment.

Section 7.8. Sole Remedy/Waiver.

(a) Buyer acknowledges and agrees that the remedies provided for in this Agreement shall be Buyer’s sole and exclusive remedy vis-à-vis Seller with respect to the subject matter of this Agreement. In furtherance of the foregoing, except as aforesaid, Buyer hereby waives and releases, to the fullest extent permitted by applicable law, any and all other rights, claims and causes of action (including rights of contributions, if any) known or unknown, foreseen or unforeseen, which exist or may arise in the future, that it may have against Seller or any of its Affiliates, with respect to the subject matter of this Agreement and the transactions contemplated hereby arising under or based upon any Applicable Law (including Environmental Laws).

(b) Seller acknowledges and agrees that the remedies provided for in this Agreement shall be its sole and exclusive remedy vis-à-vis Buyer with respect to the subject matter of this Agreement and further acknowledges that it shall have no claim against the Company for any Liability or any other matters whatsoever arising prior to or relating to any period before Closing.

In furtherance of the foregoing, except as aforesaid, Seller hereby waives and releases, to the fullest extent permitted by Applicable Law, any and all other rights, claims and causes of action (including rights of contributions, if any) known or unknown, foreseen or unforeseen, which exist or may arise in the future, that it may have against Buyer or any of its Affiliates, with respect to the subject matter of this Agreement and the transactions contemplated hereby arising under or based upon any Applicable Law (including Environmental Laws).

Section 7.9. No Consequential Damages. Notwithstanding anything to the contrary contained herein, no Indemnifying Party shall be liable to or otherwise responsible to any Indemnified Party for consequential, incidental, special, unforeseen, exemplary or punitive damages, lost profits or for diminution in value that arise out of or relate to this Agreement or the performance or breach thereof or any liability retained or assumed hereunder.

ARTICLE VIII

TERMINATION

Section 8.1. Termination.

(a) Notwithstanding anything herein or elsewhere to the contrary, this Agreement may be terminated and the transactions contemplated herein may be abandoned at any time prior to the Closing as follows:

	(1) by the mutual written consent of Buyer and Seller;

	(2) by either Seller or Buyer if an Order of a competent Governmental Authority enjoining Seller or Buyer from consummating the transactions contemplated by this Agreement shall have been entered; provided that such Order shall have become final and nonappealable; provided further that a party may not terminate this Agreement pursuant to Section 8.1(a)(2) if it or its Affiliates’ failure to perform its obligations under this Agreement resulted in or substantially contributed to the issuance of such Order;

	(3) by Seller, on the one hand, or by Buyer, on the other hand, if there shall have been a material breach of any of the covenants or agreements set forth in this Agreement on the part of Buyer (in the case of termination by Seller) or in this Agreement on the part of Seller (in the case of termination by Buyer), which breach shall not have been cured within 30 days following receipt by the breaching party of written notice of such breach from the other;

	(4) at the election of Buyer or Seller, if the Closing Date shall not occur on or before the earlier of (A) forty-five (45) days after the definitive Proxy Statement can properly be mailed to the stockholders of Rentech, Inc. in accordance with the rules and regulations of the SEC without further review by the SEC pursuant to Section 5.19 or (B) April 1, 2006 plus any Tolling Days, provided that, if the Closing Date shall not have occurred by the earlier of such dates in Subsection (A) or (B) above because Rentech, Inc. (i) was not able to mail the definitive Proxy Statement to its stockholders at least forty-five (45) days in advance of April 1, 2006 plus any Tolling Days in accordance with the rules and regulations of the SEC without further review by the SEC, (ii) was not able to complete its stockholders meeting and take a vote because such meeting had to be adjourned so that (x) Rentech, Inc. could solicit enough additional proxies to establish a quorum for a vote or (y) Rentech could respond to a restraining order blocking such stockholders meeting or (iii) was not able to issue shares of its capital stock to investors pursuant to the terms of the Financing Arrangements solely because the American Stock Exchange had not yet approved Rentech, Inc.’s listing application, then so long as Buyer is causing Rentech, Inc. to continue to use its commercially reasonable efforts to mail the definitive Proxy Statement in accordance with the rules and regulations of the SEC without further review by the SEC, take the required vote at the stockholders meeting and/or obtain American Stock Exchange approval of Rentech, Inc.’s listing application, in each case as promptly as practicable, Buyer may extend the later of such dates by up to ninety (90) calendar days in exchange for the payment of the Extension Fee for each calendar day of such extension (such date as it may be extended as provided for herein, the “Drop Dead Date”).

Notwithstanding Sections 8.1(a)(2)-(4) hereof, a party who is in material breach of any of its obligations or representations and warranties hereunder shall not have the right to terminate this Agreement pursuant to Sections 8.1(a)(2)-(4).

(b) The termination of this Agreement shall be effectuated by the delivery by the party terminating this Agreement to the other party of a written notice of such termination. If this Agreement so terminates, it shall become null and void and have no further force or effect, except as provided in Section 8.2.

Section 8.2. Effect of Termination. In the event of termination of this Agreement as provided in Section 8.1:

(a) This Agreement (other than Sections 5.4, 5.6, 8.1, 8.2 and Article IX, which provisions shall continue in full force and effect) shall forthwith become void and have no effect, except that Buyer, the Company or Seller, as the case may be, may have liability to the other parties if the basis of the termination is a willful and material breach by such party of any of its representations, warranties, covenants or agreements set forth in this Agreement, and all rights and remedies, at law or in equity, of the nonbreaching parties under this Agreement shall in that instance be preserved.

(b) The Deposit shall be returned to the Buyer, provided that, if (i) the Seller shall be eligible to terminate this Agreement in accordance with the final sentence of Section 8.1(a) and (ii) either the Seller or the Buyer shall have terminated this Agreement pursuant to Section 8.1(a)(4) in circumstances where the Buyer shall have failed to obtain Financing Arrangements sufficient to consummate the transactions contemplated herein on the Drop Dead Date, the listing approval required to satisfy Section 6.1(j) by the Drop Dead Date or the stockholder approval required to satisfy Section 6.1(k) by the Drop Dead Date, the Buyer shall receive the Deposit as a break fee, which shall be paid by release of the Deposit to Seller pursuant to the terms of the Escrow Agreement, and Seller will take all action thereunder necessary to ensure such payment is promptly made.

Buyer acknowledges and agrees that the delivery of the Deposit shall also be the sole remedy for any breaches by Buyer under this Agreement related to the failure of Buyer to obtain such Financing Arrangements or stockholder approval. Receipt of the Deposit by the Seller shall not limit any other right or remedy existing in the Seller’s favor with respect breaches by Buyer under this Agreement that are unrelated to the failure by Buyer to obtain the Financing Arrangements or stockholder approval. For purposes of this Section 8.2(b), the Buyer shall be deemed to have obtained Financing Arrangements sufficient to consummate the transactions contemplated herein if the Buyer or Rentech, Inc. shall have entered into definitive agreements with debt and/or equity investors to provide sufficient financing for the consummation of the transactions contemplated herein and the conditions to the obligations of such investors to fund under such definitive agreements could reasonably be satisfied (assuming the closing of the transactions contemplated herein) on the Drop Dead Date.

ARTICLE IX

MISCELLANEOUS

Section 9.1. Amendments; Extension; Waiver. (a) Subject to compliance with Applicable Law, this Agreement may be amended, altered, modified or waived by written instrument executed by each of the parties hereto, or in the case of waiver, by the party against whom the waiver is to be effective.

(b) No failure or delay by any party in exercising any right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

(c) To the maximum extent permitted by Law, (i) no waiver that may be given by a party shall be applicable except in the specific instance for which it was given and (ii) no notice to or demand on one party shall be deemed to be a waiver of any obligation of such party or the right of the party giving such notice or demand to take further action without notice or demand.

Section 9.2. Entire Agreement.

(a) The schedules and exhibits to this Agreement are hereby incorporated and made a part hereof and are an integral part of this Agreement.

Any capitalized terms used in any schedule or any exhibit but not otherwise defined therein shall be defined as set forth in this Agreement.

(b) This Agreement (including the schedules and exhibits hereto), together with the Confidentiality Agreement, constitutes the entire understanding and agreement of the parties hereto, except as provided herein, and supersedes all prior agreements and understandings, written and oral, among the parties with respect to the subject matter hereof.

Section 9.3. Interpretation. When a reference is made in this Agreement to a Section, Exhibit or Schedule, such reference shall be to a Section of or Exhibit or Schedule to this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 9.4. Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, the provision shall be interpreted to be only so broad as is enforceable.

	If to Seller:		▇▇▇▇▇▇▇-▇▇▇▇▇, Inc. ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇ ▇^▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ Attention: G. ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, President Facsimile: (▇▇▇) ▇▇▇-▇▇▇▇

	With a copy to:		Torys LLP ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇-▇▇▇▇ Attention: ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇▇▇ Facsimile: (▇▇▇) ▇▇▇-▇▇▇▇

	If to Buyer:		Rentech Development Corporation ▇▇▇▇ ▇▇^▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ Attention: ▇▇▇▇▇▇ ▇▇▇▇▇ Facsimile: (▇▇▇) ▇▇▇-▇▇▇▇

	With a copy to:		▇▇▇▇▇▇ & ▇▇▇▇▇▇▇ LLP ▇▇▇ ▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ Attention: ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇▇ Facsimile: (▇▇▇) ▇▇▇-▇▇▇▇

Section 9.6. Binding Effect; Persons Benefiting; No Assignment. This Agreement shall inure to the benefit of and be binding upon the parties hereto and the respective successors and permitted assigns of the parties. Except as set forth in the preceding sentence, nothing in this Agreement is intended or shall be construed to confer upon any Person other than the parties hereto and their successors and permitted assigns any right, remedy or claim under or by reason of this Agreement or any part hereof. Without the prior written consent of each of the other parties hereto, this Agreement and the rights hereunder may not be assigned by any of the parties hereto; provided, however, that Buyer may collaterally assign this Agreement and any or all rights hereunder to any lender to Buyer providing financing in connection with the transactions contemplated hereby; provided, further, that Buyer may assign this Agreement and any or all rights hereunder to a wholly-owned subsidiary of Buyer; provided, further, that Buyer shall in each such case remain liable for its obligations under this Agreement. Upon any such permitted assignment, the references in this Agreement to Buyer shall also apply to such assignee unless the context otherwise requires.

Section 9.7. Disclosure Schedules. Seller may provide information to Buyer with respect to any matter hereafter arising or discovered which, if existing or known at date of this Agreement, would have been required to be set forth in the Company Disclosure Schedule; provided, that no such information shall constitute an amendment of the Company Disclosure Schedule or of any statement, representation or warranty in this Agreement; provided, further, that if Buyer elects to proceed with the Closing, the Company Disclosure Schedule shall be deemed amended to include such information effective upon the Closing and Buyer shall be precluded from making any claim for damages under Article VII hereof based on the Company Disclosure Schedule or any representation or warranty of Seller that has been so supplemented. Inclusion of information or references to dollar amounts in the Company Disclosure Schedule shall not be construed as an admission that such information is material to Seller or the Buyer. To the extent applicable, any matter set forth in the Company Disclosure Schedule which could, based solely on the substance of the disclosure itself, reasonably be determined to be applicable to another schedule on its face shall be deemed to be set forth in each other schedule to which it is applicable. For the avoidance of doubt, if the Seller provides any information to Buyer pursuant to this Section 9.7 that would cause the failure of any condition precedent to Buyer’s obligations set forth in Sections 6.1(a) through 6.1(c) then the Buyer may terminate this Agreement pursuant to Section 8.1(a)(3) without liability and the Deposit shall be returned to Buyer.

Section 9.8. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which taken together shall constitute one and the same agreement, it being understood that all of the parties need not sign the same counterpart.

Section 9.9. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of The State of New York without reference to the choice of law principles thereof. To the fullest extent permitted by applicable law, Seller and Buyer hereby unconditionally and irrevocably waive any claim to assert that the law of any other jurisdiction governs this Agreement. Seller and Buyer hereby agree and consent to be subject to the exclusive jurisdiction of the United States District Court for the Southern District of New York, and in the absence of such Federal jurisdiction, Seller and Buyer consent to be subject to the exclusive jurisdiction of a court of The State of New York located in such district and hereby waive the right to assert the lack of personal or subject matter jurisdiction or improper venue in connection with any such suit, action or other proceeding. In furtherance of the foregoing, each of Seller and Buyer (i) waives the defense of inconvenient forum, (ii) agrees not to commence any suit, action or other proceeding arising out of this Agreement or any transactions contemplated hereby other than in any such court, and (iii) agrees that a final judgment in any such suit, action or other proceeding shall be conclusive and may be enforced in other jurisdictions by suit or judgment or in any other manner provided by law. THE PARTIES HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT SUCH PARTIES MAY HAVE TO A TRIAL BY JURY WITH RESPECT TO ANY SUIT OR ACTION ARISING OUT OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. BUYER HEREBY CERTIFIES THAT NONE OF SELLER, SENIOR MANAGEMENT OR THEIR REPRESENTATIVES HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SELLER WOULD NOT SEEK TO ENFORCE THIS WAIVER OF RIGHT TO JURY TRIAL. FURTHER, BUYER ACKNOWLEDGES THAT SELLER RELIED ON THIS WAIVER OF RIGHT TO JURY TRIAL AS A MATERIAL INDUCEMENT TO SELLER TO ENTER INTO THIS AGREEMENT.

Section 9.10. Mutual Drafting. The parties hereto have been represented by counsel who have carefully negotiated the provisions hereof. As a consequence, the parties do not intend that the presumptions of any laws or rules relating to the interpretation of contracts against the drafter of any particular clause should be applied to this Agreement and therefore waive their effects.

Section 9.11. Certain Understandings. Each of the parties is a sophisticated legal entity or person that was advised by experienced counsel and, to the extent it deemed necessary, other advisors in connection with this Agreement. Accordingly, each of the parties hereby acknowledges that (i) no party has relied or will rely in respect of this Agreement or the transactions contemplated hereby upon any document or written or oral information previously furnished to or discovered by it or its representatives, other than this Agreement (including the Company Disclosure Schedule), (ii) there are no representations or warranties by or on behalf of any party hereto or any of its respective affiliates or representatives other than those expressly set forth in this Agreement, and (iii) the parties’ respective rights and obligations with respect to this Agreement and the events giving rise thereto will be solely as set forth in this Agreement.

Section 9.12. Specific Performance. Buyer and Seller each agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by them in accordance with the terms hereof and that each party shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed as of the date first above written.
