(i) Prior to Closing, Buyer and Sellers shall conduct a physical inventory of the Facilities for the purpose of determining the Inventory to be included in the calculation of Working Capital. At least three Business Days prior to the Closing Date, Sellers shall deliver to Buyer a certificate executed by Sellers (the “Initial Closing Date Statement”), setting forth a good faith estimate of the Working Capital (the “Estimated Working Capital”) as of the Closing Date. The Initial Closing Date Statement shall be prepared in accordance with Sellers’ historical accounting methods, policies, practices and procedures, with consistent classifications, judgments, thresholds and estimation methodology reflected or assumed therein.

(ii) At the Closing, Buyer shall pay to or for the account of Sellers (as directed by Sellers) (A) the sum of Four Hundred Eighty Million Euro (€480,000,000) (the “Base Amount”), plus the Estimated Working Capital Adjustment, minus (B) the total of the amounts outstanding as of the close of business on the day immediately preceding the Closing Date for

the items listed on Schedule 2(d)(ii) in cash, payable by wire transfer of immediately available funds in accordance with the written instructions of Sellers provided by Sellers to Buyer (the “Closing Payment”). The Closing Payment shall constitute the “Estimated Purchase Price.”

(iii) As soon as reasonably practicable, but not later than 90 calendar days after the Closing Date, Buyer shall (A) prepare a statement of the calculation of Working Capital as of the Closing Date, the Final Working Capital Adjustment and the Final Specified Deductions (the “Closing Date Statement”), and (B) deliver to Sellers the Closing Date Statement. The calculation of the items set forth in the Closing Date Statement shall be prepared in accordance with Sellers’ historical accounting methods, policies, practices and procedures, with consistent classifications, judgments, thresholds and estimation methodology, as were used in the preparation of the items set forth in the Initial Closing Date Statement.

(iv) In connection with the preparation of the Closing Date Statement, Sellers shall permit Buyer and their representatives reasonable access to books and records, personnel, and facilities of Sellers to permit them to prepare the Closing Date Statement. Sellers shall have the right to review the work papers of Buyer underlying or utilized in preparing the Closing Date Statement to the extent reasonably necessary to verify the accuracy and fairness of the presentation of the Closing Date Statement and calculation of the Final Working Capital Adjustment in conformity with this Agreement.

(v) Within 20 calendar days after its receipt of the Closing Date Statement, Sellers either shall inform Buyer in writing that the Closing Date Statement is acceptable or object thereto in writing, setting forth a specific description of each of its objections. If Sellers so object and the Parties do not resolve such objections on a mutually agreeable basis within 10 calendar days after Buyer’s receipt of Sellers’ objections, the remaining disputed items shall be resolved within an additional 20 calendar days by an internationally recognized independent accounting firm selected by Buyer and reasonably acceptable to Sellers (the “Referral Firm”). Upon (A) the agreement of the Parties, (B) the decision of the Referral Firm or (C) if Sellers fail to deliver an objection to Buyer within the first 20-day period referred to above, then the Closing Date Statement, as so adjusted (the “Final Closing Date Statement”), shall be final, conclusive and binding against the Parties hereto. The statement of Working Capital set forth in the Final Closing Statement shall be the “Final Working Capital” for all purposes hereunder. Sellers shall make available to Buyer (upon request following the giving of any objection to the Closing Date Statement) the workpapers of Sellers generated in connection with their review of the Closing Date Statement.

(vi) In resolving any disputed item, the Referral Firm (A) shall be bound by the provisions of this Section 2(d), (B) may not assign a value to any item greater than the greatest value claimed for such item or less than the smallest value for such item claimed by either Buyer or Sellers and (C) shall limit its decision to such items as are in dispute. The fees, costs and expenses of the Referral Firm shall be borne by Buyer, on the one hand, and by Sellers, on the other hand, in inverse proportion to their relative success in the resolution of such disputed items.

(vii) The “Final Purchase Price” shall mean (A) the sum of the Base Amount, plus the Final Working Capital Adjustment, minus (B) the total of the amounts outstanding as of the close of business on the day immediately preceding the Closing Date for the items listed on Schedule 2(d)(ii) as adjusted to take into account the Final Specified Deductions. Promptly after their receipt of the Final Closing Date Statement, Sellers and Buyer shall compute the difference, if any, between the Estimated Purchase Price and the Final Purchase Price. If the Estimated Purchase Price exceeds the Final Purchase Price, then Buyer shall be entitled to receive, promptly and in any event within five Business Days, from Sellers an amount in cash equal to such excess amount. If the Estimated Purchase Price is less than the Final Purchase Price, Sellers shall be entitled to receive, promptly and in any event within five Business Days, from Buyer an amount in cash equal to such deficiency. The amount of any payment to be made pursuant to this Section 2(d)(vii) shall bear simple interest from and including the Closing Date to but excluding the date of payment at a rate per annum equal to the rate of interest published by the Wall Street Journal (Eastern edition) on the Closing Date as the “prime rate” at large U.S. money center banks. Such interest shall be payable at the same time as the payment to which it relates.

(viii) Within 90 days of the Closing Date, Buyer shall pay Sellers an amount equal to the Excluded Accounts Payable as of the Closing Date.

(1a) German VAT Act or a comparable provision (transfer of business as a whole) and the Parties will file their respective tax returns and preliminary monthly tax returns (Voranmeldungen) on that basis. To the extent that it shall nevertheless be determined by means of a tax audit of the business of German Seller that the sale of the Oberhausen Assets under this Agreement shall be subject to VAT and should the tax office deny the application of Sec. 1 para.

German Seller will issue an invoice in line with applicable law especially fulfilling all requirements under Sec 14, 14a of the German VAT Act.

(B) The sale of assets other than those referred to under subsection (A) above that are exempt from VAT under Sec 4 of the German VAT Act remains tax free. German Seller will not exercise its option right under Sec 9 of the German VAT Act with respect to such assets.

(B) the purchase of Products from another Person (excluding any Affiliate of Parent or either Seller), the incorporation of Products into any material, and the manufacture, marketing, distribution, sale, supply or sale of such material by Parent, either Seller or any of their Affiliates;

(C) the ownership by Parent, either Seller or any of their Affiliates, individually or in the aggregate, of 8% or less of the outstanding voting securities of any Person engaged in the Restricted Activity, regardless of whether or not such securities are listed on a national or foreign securities exchange or on the NASDAQ National Market;

(D) the acquisition by Parent, either Seller or any of their Affiliates of any Person (whether through the purchase of stock or assets or by way of merger, consolidation or other transaction) engaged in the Restricted Activity (the “Acquired Person”) so long as the gross sales of the Restricted Activity of such Acquired Person do not exceed 8% of the total gross sales of such Acquired Person during the trailing 12-month period ended as of the last day of the calendar month that is at least 30 days but not more than 60 days prior to the date that the definitive documentation with respect to such acquisition is executed; or

(E) the engagement in the Restricted Activity by any Person (other than by or through Parent or either Seller) that acquires Control of Parent or either Seller (an “Acquiring Business”); provided, however, that such Person is not an Affiliate of Parent or either Seller as of the date hereof and was not an Affiliate of Parent or either Seller immediately prior to the transaction pursuant to which such Person acquired Control of Parent or such Seller.

(iii) Subject to the restrictions in the succeeding sentence, if Parent or either Seller, directly or through any of their Affiliates, acquires during the Restricted Period any interest in a Person conducting the Restricted Activity in accordance with Section 6(c)(ii)(D) above, Parent or such Seller shall give Buyer written notice of such acquisition promptly after such acquisition is completed and in such notice shall offer to sell to Buyer that portion of the business of the acquired entity engaged in the Restricted Activity (a “Restricted Business”) at a price equal to the Applicable Multiple and Metric of the Restricted Business. “Applicable Multiple and Metric” means the multiple and metric (including the time period over which such metric is measured) used to determine the price paid by Parent or such Seller to make such acquisition. Buyer shall have 60 days from the date such notice is deemed effective pursuant to Section 11(g) to determine whether to purchase the Restricted Business. During such 60-day period, Parent or such Seller shall make available to Buyer such books and records regarding the Restricted Business as Buyer shall reasonably request, subject to Buyer entering into a customary confidentiality agreement. If Buyer gives Parent or such Seller written notice of its acceptance

of such offer within such 60-day period, then such parties shall use commercially reasonable efforts to close such transaction as soon as reasonably practicable thereafter. If Buyer gives Parent or such Seller written notice that it rejects such offer or if Buyer fails to give Parent or such Seller written notice accepting such offer within such 60-day period, then Parent or such Seller shall have the right to operate such Restricted Business as it sees fit in its sole discretion, except that neither Parent nor either Seller nor any of their Affiliates shall, directly or indirectly, (A) disclose any confidential or proprietary information related to the Purchased Assets to the Restricted Business or (B) license or otherwise permit the Restricted Business to use any of the Transferred Intellectual Property (1) during the time that Parent, either Seller or any of their Affiliates own any interest in such Person (and such Person continues to engage in the Restricted Business), (2) in connection with the sale of such Person to any Person that is not an Affiliate of Parent or either Seller, or (3) thereafter.

(iv) Except to the extent otherwise permitted under Section 6(c)(ii), Parent and each Seller agrees that, during the Restricted Period, neither Parent nor any Seller nor any of their Affiliates shall: (A) cause, solicit, induce or encourage any Employees to leave such employment, provided, however, this prohibition shall not apply to any Employee who responds to a public solicitation not targeted directly at such Employee or the Business; or (B) cause, induce or encourage any material customer or supplier of the Business to terminate or modify any such relationship. Additionally, Parent and each Seller agree that, during the two-year period following the Closing Date, neither Parent nor any Seller nor any of their Affiliates shall hire, employ or otherwise engage the services of any of the Persons set forth on Schedule 6(c)(iv), unless Buyer has terminated such Person’s employment with Buyer or Buyer’s Affiliate prior thereto.

(v) From and after the date hereof, Parent and Sellers shall not and shall cause their Affiliates and their respective officers and directors not to, directly or indirectly, disclose, reveal, divulge or communicate to any Person other than authorized officers, directors and employees of Buyer or use or otherwise exploit for its own benefit or for the benefit of anyone other than the Buyer, any Confidential Information (as defined below). Sellers and their officers, directors and Affiliates shall not have any obligation to keep confidential any Confidential Information if and to the extent disclosure thereof is specifically required by law; provided, however, that in the event disclosure is required by applicable law, Sellers shall, to the extent reasonably possible, provide Buyer with prompt notice of such requirement prior to making any disclosure so that Buyer may seek an appropriate protective order. For purposes of this Section 6(c)(v), “Confidential Information” means any information with respect to the Business, including methods of operation, customers, customer lists, products, prices, fees, costs, Technology, inventions, trade secrets, Know-How, Software, marketing methods, plans, personnel, suppliers, competitors, markets or other specialized information or proprietary matters. Confidential Information does not include, and there shall be no obligation hereunder with respect to, information that (i) is generally available to the public on the date of this Agreement or (ii) becomes generally available to the public other than as a result of a disclosure not otherwise permissible thereunder.

(vi) The Parties acknowledge and agree that the time, scope, and other provisions of this Section 6(c) have been specifically negotiated by sophisticated commercial parties and specifically hereby agree that such time, scope and other provisions are reasonable under the circumstances. The Parties further agree that if, at any time, despite the express agreement of the Parties, a court of competent jurisdiction holds that any portion of this Section 6(c) is unenforceable because any of the restrictions therein are unreasonable, or for any other reason, such decision shall not affect the validity or enforceability of any of the other provisions of this Agreement, and the maximum restrictions of time or scope reasonable under the circumstances, as determined by such court, will be substituted for any such restrictions which are held unenforceable.

(d) Use of “Celanese” Name. As soon as practicable, and in any event within 180 days after the Closing Date, Buyer shall not use or display the name “Celanese” or variations thereof, trade names, logos or identifiers using such name or otherwise owned by or licensed to either Seller or its Affiliates, without the prior written consent of Sellers.

(e) Taxes; Prorations.

(i) Tax Indemnification. Except to the extent taken into account in determining the Final Working Capital, Sellers hereby agree, jointly and severally, to be liable for and to indemnify and hold Buyer and its Affiliates (including the Companies) and their respective stockholders, officers, directors, employees, agents and assigns (collectively, the “Buyer Indemnified Parties”) harmless from and against, and pay to the Buyer Indemnified Parties the amount of, any and all losses or damages resulting from, arising out of, or incurred with respect to, any claims that may be asserted by any party, based on, attributable to, or resulting from (i) all Taxes of or with respect to the Companies (or any predecessors thereof) or attributable to the Purchased Assets (A) for any taxable period ending on or before the Closing Date, (B) for the portion of any Straddle Tax Period ending at the close of business on the Closing Date (determined as provided in Section 6(e)(iv) and Section 6(e)(v)) and for the avoidance of doubt including any trade Tax (Gewerbesteuer) triggered on the level of Infraserv due to the transactions contemplated by this Agreement; and (C) for any taxable period ending after the Closing Date to the extent additional VAT is levied based upon Section 1 para. 1a 3rd sentence, Sections 15(a) or 17 of the German VAT Act and is related to supplies made or received prior to the Closing Date; (ii) the failure of any of the representations and warranties contained in Section 3(m) to be true and correct (determined without regard to any qualification related to materiality contained therein) or the failure to perform any covenant contained in this Agreement with respect to Taxes; (iii) any Seller Taxes; and (iv) any liability or obligation provided for under Section 75, 73 of the German General Tax Code (Abgabenordnung) or Section 1 (para. 1a of the German VAT Act) or any similar provision which relates to Taxes incurred by Sellers or the Companies in a taxable period or portion thereof ending on or prior to the Closing Date. By way of clarification, with respect to any losses or damages arising out of a matter that constitutes both a breach of a representation or warranty and an Excluded Liability, such losses and damages shall be treated as an Excluded Liability and Sellers’ indemnification obligation hereunder shall not require Sellers to indemnify the Buyer Indemnified Parties against the same losses and damages twice.

(ii) Sales and Transfer Taxes. All sales and transfer taxes other than VAT (including real property transfer taxes and including such taxes accrued at the level of Infraserv Oberhausen) arising in connection with the sale and transfer of the Purchased Assets will be shared equally between Buyer, on the one hand, and Sellers on the other hand, and Buyer or Sellers, as the case may be, will file, to the extent required by applicable law, all necessary Tax Returns required to be supplied to any Taxing Authority with respect to such sales and transfer Taxes.

(iii) Filing of Tax Returns; Payment of Taxes.

(A) Sellers shall cause each Company to timely file all Tax Returns required to be filed by it on or prior to the Closing Date and shall pay or cause to be paid all Taxes shown due thereon. All such Tax Returns shall be prepared in a manner consistent with prior practice. Sellers shall provide Buyer with copies of such completed Tax Returns at least twenty days prior to the due date for filing thereof, along with supporting workpapers, for Buyer’s review and approval, such approval not to be unreasonably withheld or delayed.

(B) Buyer will be responsible for the preparation and filing of all Tax Returns in respect of the Purchased Assets and the Companies which are due after the Closing Date (other than for Taxes with respect to periods for which the consolidated, unitary, and combined Tax Returns of Sellers will include the operations of any of the Companies or the Purchased Assets); provided, however, that, for any Tax Return for Taxes for which Buyer is to be indemnified under Section 6(e)(i), Buyer shall provide the Sellers with copies of such completed Tax Returns at least twenty days prior to the due date for filing thereof, along with supporting workpapers, for the Sellers’ review and approval, such approval not to be unreasonably withheld or delayed. Subject to the rights to payment from the Sellers under paragraph (C) below, Buyer will make all payments required with respect to any such Tax Return.

(C) In the event of any disagreement between the Sellers and Buyer with respect to any Tax Return for which the other party has the right of review and approval (as described in paragraphs (A) and (B) above), the Sellers and Buyer shall attempt in good faith to resolve any such disagreement regarding such Tax Return prior to the due date for filing. In the event that the Sellers and Buyer are unable to resolve any dispute with respect to such Tax Return at least ten days prior to the due date for filing, such dispute shall be resolved pursuant to Section 6(e)(xi), which resolution shall be binding on the parties.

(D) Not later than five days prior to the due date for the payment of Taxes on any Tax Returns which Buyer has the responsibility to cause to be filed pursuant to paragraph (B) above, the Sellers shall pay to Buyer the amount of Taxes as reasonably determined by Buyer, owed by the Sellers pursuant to the provisions of Section 6(e)(iv) and Section 6(e)(v). No payment pursuant to this paragraph (D) shall excuse the Sellers from their indemnification obligations pursuant to Section 6(e)(i) if the

amount of Taxes as ultimately determined (on audit or otherwise) for the periods covered by such Tax Returns exceeds the amount of the Sellers’ payment under this paragraph (D).

(iv) Straddle Period Tax Allocations. Each Company will, unless prohibited by applicable law, close the taxable period of such Company as of the close of business on the Closing Date. For the avoidance of doubt, no Company is obligated to change its fiscal year (other than as provided for in Section 5(i)) to end as of the Closing Date. If applicable law does not permit a Company to close its taxable year on the Closing Date, Taxes (other than property taxes which are subject to the provisions of Section 6(e)(v) below), if any, attributable to such Straddle Tax Period shall be allocated (i) to the Sellers for the period up to and including the close of business on the Closing Date, and (ii) to Buyer for the period subsequent to the Closing Date. Any allocation of income or deductions required to determine any Taxes attributable to a Straddle Tax Period shall be made by means of a closing of the books and records of each Company as of the close of the Closing Date, provided that exemptions, allowances or deductions that are calculated on an annual basis (including, but not limited to, depreciation and amortization deductions) shall be allocated between the period ending on the Closing Date and the period after the Closing Date in proportion to the number of days in each such period. Buyer shall be responsible for any Tax resulting from transactions occurring after the Closing and prior to the close of business of Closing Date outside of the Ordinary Course of Business and other than any transactions contemplated by this Agreement.

(v) Property Taxes. Real and personal property Taxes relating to the Purchased Assets and the Companies’ assets for the taxable period in which the Closing Date occurs will be equitably prorated (in the event that final assessed Tax amounts are not available for the Closing, the proration will be based upon the Tax bill for the last full finally assessed Tax year) between Buyer and Sellers, as follows: Sellers shall be responsible for all such Taxes assessed for any period up to and including the Closing Date, and Buyer shall be responsible for all such Taxes for the period commencing with the day after the Closing. All Taxes will be prorated on the assumption that an equal amount of Taxes applies to each day of the year, regardless of how any installment payments are billed or made. Within 30 Business Days after any such Taxes prorated on an estimated basis are finally assessed, Sellers shall pay to Buyer or Buyer shall pay to Sellers, as the case may be, its proportionate share of any difference between the estimated and assessed Taxes.

(vi) Abatements, Refunds and Credits. Sellers shall be entitled to any abatements, refunds or credits of Taxes relating to the Purchased Assets or the Companies for the period prior to and including the Closing Date, net of any costs incurred or Taxes payable in respect of the receipt of such abatements, refunds or credits. Buyer will promptly notify and forward to Sellers the amounts of any such abatements, refunds or credits received by Buyer within 15 days after receipt thereof. Any abatements, refunds and credits of Taxes relating to a Straddle Tax Period shall be shared, net of any costs incurred or Taxes payable in respect of the receipt of such abatements, refunds or credits, proportionately between Sellers and Buyer based on the portion of the taxable period in question that each owned the Purchased Assets or the

Companies. Buyer shall not amend any Tax Return of a Company covering any taxable period that ends on or prior to the Closing Date unless required by law.

(vii) Tax Audits. After the Closing, Buyer will notify Sellers in writing, within fifteen (15) days after its receipt of any correspondence, notice or other communications from a Taxing Authority or any representative thereof, of any pending or threatened Tax audit, or any pending or threatened judicial or administrative proceedings that involves Taxes relating to the Purchased Assets or the Companies for the period prior to and including the Closing, and furnish Sellers with copies of all correspondence received from any such Taxing Authority in connection with any audit or information request with respect to any such Taxes relating to the Purchased Assets or the Companies for the period prior to and including the Closing to the extent such correspondence relates to an amount that is subject to indemnification by the Sellers pursuant to Section 6(e)(i).

(viii) Tax Claims. Notwithstanding any provision of this Agreement to the contrary, with respect to any Claim for abatement, refund, audit examination, notice of deficiency or assessment or any judicial or administrative proceeding that involves Taxes relating to the Purchased Assets or the Companies, (collectively, a “Tax Claim”), Buyer shall have the right, at the expense of the Sellers to the extent such Tax Claim is subject to indemnification by the Sellers pursuant to Section 6(e)(i) hereof, to represent the interests of the Companies in any such Tax Claim (or to otherwise prosecute or contest such Tax Claim relating to the Purchased Assets); provided, that with respect to a Tax Claim that is subject to indemnification by the Sellers pursuant to Section 6(e)(i), (A) Buyer shall keep the Sellers reasonably informed of the progress of such Tax Claim and consult seriously and in good faith with the Sellers and their tax advisors with respect to any issue relating to such Tax Claim; (B) Buyer shall provide the Sellers with copies of all correspondence, notice or other written materials received from any Taxing Authorities and shall otherwise keep the Sellers and their tax advisors advised of significant developments in the Tax Claim and of significant communications involving representations of the Taxing Authorities; (C) Buyer shall provide the Sellers with a copy of any written submission to be sent to a Taxing Authority prior to the submission thereof and shall give serious and good faith consideration to any comments or suggested revisions that the Sellers or their tax advisors may have with respect thereto; and (D) there will be no settlement, resolution, or closing or other agreement with respect thereto without the consent of the Sellers, which consent will not be unreasonably withheld.

(ix) Proration of Certain Expenses. Except as set forth in Sections 6(e)(i) through 6(e)(viii), all expenses relating to the business operations of the Facilities and Purchased Assets and the Companies that are normally pro-rated, including water and sewer use charges, other charges in the nature of utility services, rents, permit, license, registration, compliance or other fees for Permits, for the period prior to and including the Closing Date will be for the account of Sellers, and all such expenses for the period after the Closing Date will be for the account of Buyer, all as determined by the accrual method of accounting. All prorations will be made on the basis of the actual number of days of the month or year, as applicable, which will have elapsed as of the Closing Date and based upon a 365-day year. Sellers shall prepare a good-faith estimate of each Party’s respective pro-rated share of such expenses as of the Closing

Date. At the Closing, such estimate shall be compared to the actual expenses that have been paid as of the Closing by Sellers, and the Parties shall make such payments to each other as may be required in order to cause the Sellers’ actual expenses paid as of the Closing conform to Sellers’ estimated pro-rata portion of such expenses. Within 90 days following the Closing, Sellers shall calculate the actual expenses relating to the business operations of the Facilities and the Purchased Assets and the Companies and the pro-rata portion of same for each of Sellers and Buyer as of the Closing Date and the difference, if any, between such actual pro-rata portions of such expenses for each of Sellers and Buyer and the estimated pro-rata portions of such expenses for each of Sellers and Buyer prepared by Sellers in accordance with this Section 6(e)(ix), which difference, if any, shall be set forth in writing by Sellers. Payment of the difference (which difference shall be adjusted to account for any actual payment made between the Parties on the Closing Date as contemplated by this Section 6(e)(ix) shall be made within 10 business days following delivery of such written statement by wire transfer in US dollars in immediately available funds to the account designated by the recipient Party and delivered to the paying Party.

(x) Costs and Expenses. Except to the extent specifically provided herein, whether or not the transactions contemplated hereby are consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be borne by the Party incurring such costs and expenses. Notwithstanding anything to the contrary herein, Buyer will be responsible for (A) all costs and expenses associated with the obtaining of any title insurance policy and all endorsements thereto that Buyer elects to obtain, (B) all fees and expenses of any nature whatsoever incurred in obtaining the approval of any Governmental Entity for the payment by Buyer of the Estimated or Final Purchase Price hereunder, and (C) all costs and fees in connection with the assignment of the registered Transferred Intellectual Property and the Real Property to Buyer before any Governmental Entity (except any costs incurred to clear Sellers’ title prior to such assignment). Sellers and Buyer each represent and warrant to the other, respectively, that, except as set forth on Schedule 6(e)(x), no broker, finder or other person is entitled to any brokerage fees, commissions or finder’s fees in connection with the transaction contemplated hereby by reason of any action taken by the party making such representation. Each of Sellers and Buyer will pay to the other, or otherwise discharge, and will indemnify and hold the other harmless from and against, any and all Claims for all brokerage fees, commissions, and finders’ fees (other than as described above) incurred by reason of any action taken by the indemnifying party.

(xi) Disputes. Any dispute as to any matter covered hereby shall be resolved by an independent accounting firm mutually acceptable to Sellers and Buyer. The fees and expenses of such accounting firm shall be borne equally by Sellers, on the one hand, and Buyer on the other. If any dispute with respect to a Tax Return is not resolved prior to the due date of such Tax Return, such Tax Return shall be filed in the manner which the party responsible for preparing such Tax Return deems correct.

(xii) Time Limits. Any claim for indemnity under this Section 6(e) may be made at any time prior to 60 days after the expiration of the applicable Tax statute of limitations

with respect to the relevant taxable period (including all periods of extension, whether automatic or permissive).

(xiii) Exclusive Tax Remedy. The indemnification provided for in this Section 6(e) shall be the sole remedy for any claim in respect of Taxes, including any claim arising out of or relating to a breach of Section 3(m). In the event of a conflict between the provisions of this Section 6(e), on the one hand, and the provisions of Section 8, on the other, the provisions of this Section 6(e) shall control. For the avoidance of doubt, the indemnity for Taxes provided for in this Section 6(e) shall not be subject to the “Indemnification Threshold” or “Indemnification Cap” as set forth in Section 8(e) or the minimum €20,000 threshold described in the last sentence of Section 8(e).

(xiv) U.S. Entity Classification Election. Parent shall make or cause to be made a U.S. entity classification election pursuant to Treasury regulation § 301.7701-3(c) (“U.S. Election”) with respect to the Entire Eoxo Interest after acquiring the Degussa Interest and prior to the Closing Date. The effect of such U.S. Election shall be to treat Eoxo as a disregarded entity for U.S. federal income tax purposes prior to the Closing Date.

(f) Post Closing Cooperation by Buyer. The Parties recognize that, notwithstanding the transfer of the Purchased Assets to Buyer, following the Closing, Sellers will need access to certain information, records and assistance with respect to the Purchased Assets and the Companies’ assets relating to the period prior to Closing. Accordingly, the Parties agree as follows:

(i) Information and Administrative Support. For a period of seven years after the Closing Date (or, if requested in writing by Sellers within seven years after the Closing Date, until the closing of the examination of Sellers’ federal and state income Tax Returns for all periods prior to and including the Closing Date, if later), Buyer agrees that it will, promptly following the request of any Seller and at Sellers’ expense, provide such information and administrative support as will be reasonably requested by any Seller to enable Sellers to comply with its obligations with respect to the issuance of Forms W-2, 1099 and other Tax reports, reports and notices relating to pension, profit sharing, health and other plans, income Tax Returns, preparation of financial statements and completion of Sellers’ audit for the two fiscal years ended December 31 following the Closing Date, and other similar matters.

(ii) Books and Records. For a period of seven years after the Closing Date (or, if requested in writing by Sellers within seven years after the Closing Date, until the closing of the examination of Sellers’ federal and state income Tax Returns for all periods prior to and including the Closing Date, if later), Buyer will not dispose of any Records relating to any of the Purchased Assets or the Companies’ assets delivered to it by Sellers without first giving notice to Sellers of its intent to so dispose of such Records, and permitting Sellers to retain or copy such Records at Sellers’ expense as Sellers may select. During such period, Buyer will permit Sellers to examine and make copies, at Sellers’ expense, of such Records for any reasonable purpose, including any litigation now pending or hereafter commenced against any Seller, or the preparation of Tax Returns.

(iii) Employees. For a period of six years after the Closing Date, Buyer will make available to Sellers on a reasonable basis and as requested from time to time by Sellers after the Closing Date at Sellers’ expense, those of Buyer’s employees with knowledge of, or relevant to, the matters described in this Section 6(f) for the purpose of consultation, investigation or testimony in connection therewith.

(iv) Return of Records. After the Closing Date, Buyer shall deliver to Sellers any records of Sellers transferred to Buyer pursuant to this Agreement if such records (A) were transferred to Buyer by mistake, (B) are unrelated to the Purchased Assets or the Companies’ assets or (C) were not otherwise contemplated to be transferred to Buyer pursuant to this Agreement. Buyer shall be obligated to immediately deliver to Sellers the above-referenced records upon Sellers’ request therefor or upon Buyer’s becoming aware of any such records.

(g) Further Assurances.

(i) From and after the Closing Date, Sellers shall pay and discharge, in accordance with past practice but not less than on a commercially reasonable timely basis, all accounts payable incurred by Sellers or the Companies on or prior to the Closing Date in respect of the Business and included in the Excluded Liabilities.

(ii) Sellers and Buyer agree that after the Closing Date they will hold in trust and will promptly transfer and deliver to the proper recipient thereto, from time to time as and when received by them, any cash, checks with appropriate endorsements (using their commercially reasonable efforts not to convert such checks into cash), or other property that they may receive on or after the Closing which properly belongs to the other party, including without limitation, any insurance proceeds, and will account to the other for all such receipts.

(h) Notification of Transfer. At all times following the Closing, Buyer will notify promptly (with a copy of such notice to Sellers) all relevant Governmental Entities and third Persons of the change in ownership of the Purchased Assets resulting from the transactions contemplated herein, to the extent required by applicable law or any Material Contract.

(i) Special Indemnification. Unless expressly stated otherwise in this Agreement, Buyer shall indemnify each Seller and any Affiliate of any Seller if and to the extent:

(A) a Seller and/or any Affiliate of any Seller is held liable for any Liabilities arising out of or in connection with (i) the conduct of the business of, or any action taken by a Seller and/or any Affiliate of any Seller with respect to, any Company, European Pipeline, Neu-Oberhausen GmbH or Studiengesellschaft mbH or (ii) a Seller and/or any Affiliate of any Seller being directly or indirectly a partner or shareholder of such Company, European Pipeline, Neu-Oberhausen GmbH or Studiengesellschaft mbH, in each case, to the extent any Claim is made against a Seller and/or any Affiliate of any Seller or a Seller and/or any Affiliate of any Seller is held liable by a third party (including any Governmental Entity), or a Company, European Pipeline, Neu-Oberhausen GmbH or Studiengesellschaft mbH, and such Seller would not be liable to Buyer under this Agreement for such Claim; or

(B) a Seller and/or any Affiliate of any Seller is held liable by any third party or a Company (1) as former unlimited partner of Infraserv Oberhausen under Sections 161 para. 2, Section 160 para. 1 German Commercial Code (Handelsgesetzbuch) or (2) as former limited partner of Infraserv Oberhausen under Section 172 para. 4 German Commercial Code (Handelsgesetzbuch), provided that such Seller would not be liable to Buyer under this Agreement for such liability.

This Section shall constitute with respect to Sellers and their Affiliates a contract for the benefit of a third party.

(j) Environmental Matters.

(i) Transfer of Environmental Permits. Prior to and following the Closing, the Parties agree to cooperate and take all actions reasonably necessary to effectuate the transfer of Permits issued pursuant to Environmental Laws or, if the transfer of such Permits is not allowed under Environmental Laws, the Parties agree to cooperate and take all actions reasonably necessary to obtain new Permits required pursuant to Environmental Laws. To this end and without limiting the generality of the foregoing, Sellers shall (a) transfer the existing Title V air permit at Bay City to Purchaser and shall independently apply for any air permits required for the Sellers retained operations, (b) use commercially best efforts to cause the Texas Commission on Environmental Quality to separate the obligations under the Bay City Resource Conservation and Recovery Act (“RCRA”) hazardous waste permit so that (A) the permit issued to Buyer shall be limited to the two active RCRA units (the hazardous waste burning boilers and the container storage area) and (B) Sellers obtain a permit or RCRA order to address all corrective action obligations, including, but not limited to those associated with the RCRA closed units and the RCRA Corrective Action Unit Landfill F-2/F-3.

(ii) Until such time as the Governmental Entities have transferred the RCRA permit to Buyer, separated the obligation the obligation thereunder as set forth in subsection (j)(i) above and approved the form of financial assurances that Buyer must post to continue to operate the two active RCRA waste management units, Sellers shall maintain its financial assurances. Once the Governmental Entities have accepted Buyer’s form of financial assurances and those assurances have been put in place, Sellers shall be obligated only to maintain the financial assurances necessary to satisfy the Governmental Entities with respect to the on-going RCRA investigation and Remediation.

(iii) Single Site Petition. The Parties agree to join in filing single site petitions pursuant to 30 TAC 101.2(b) for each of their Bishop and Bay City operations.

(k) Marl Demolitions. Sellers shall reimburse the Buyers Indemnified Parties for all necessary and reasonable third-party costs and expenses incurred after the Closing and required by law or by the contracts with Degussa Immobilien GmbH and Co. KG for the demolition and removal of the butanol distillation and MD-hydrogeneration units, for which there was a decision to close prior to Closing and which are either closed or will subsequently be closed, at the Company Facility in Marl, Germany.

(l) License of Retained Intellectual Property. The assignment of the Transferred Intellectual Property to Buyer is hereby subject to retention by Sellers of an irrevocable, worldwide, perpetual, non-exclusive, nontransferable, royalty-free license, with the right to sublicense without consent, under U.S. Patent No. ###-###-####, Rhodium Recovery from Hydroformylation (Seller Docket No. 7060) (the “Licensed Patent”) and all Know-How primarily used or held for use in connection with the Business or the Products (the “Licensed Know-How”), to make, have made, use, copy, display, perform, import, sell, offer to sell, create derivative works and modifications, distribute or otherwise dispose of products and services that incorporate or otherwise use the Licensed Patent and/or Licensed Know-How, provided that the foregoing license shall not include any right to use or otherwise exploit the Licensed Patent or Licensed Know-How in the oxo chemicals field. Sellers hereby grant Buyers an irrevocable, worldwide, perpetual, royalty-free license, with the right to sublicense without consent, under the Retained Know-How. Said license of Retained Know-How shall be sole and exclusive within the oxo chemicals field. To facilitate Buyer’s commercial use of the Retained Know-How, Sellers further agree to transfer to Buyer a copy of any Retained Know-How at a cost no greater than the cost to Sellers for such transfer.

(m) Seller Guarantees.

(i) Buyer acknowledges that Sellers have the outstanding guarantees listed on Schedule 6(m) (collectively, the “Seller Guarantees”). Buyer and Sellers agree that, promptly following the date hereof, they shall contact the beneficiaries of such Seller Guarantees, and Sellers and Buyer shall use commercially reasonable efforts and cooperate (including arranging meetings or telephone conferences with such beneficiaries) to obtain from the beneficiaries the release of Sellers from the Seller Guarantees effective as of the Closing Date, and to obtain a consent of such beneficiaries to accept replacement guarantees, letters of credit or other financial assurances from the Lenders or other financial institutions. Sellers agree that following the Closing they shall continue any remaining Seller Guarantees in an aggregate amount not to exceed €40,000,000 (the “Continuing Guarantees”), and Buyer acknowledges that Sellers may terminate prior to Closing any Seller Guarantees in excess of the Continuing Guarantees; provided, however, that Sellers shall only be required to keep (A) the Continuing Guarantees remaining outstanding for up to (and not more than) 30 days following the Closing Date, and (B) Continuing Guarantees equal to not more than €10,000,000 in the aggregate outstanding for 60 days following Closing. After the 60^th day following Closing, Sellers shall not be obligated to maintain any Seller Guarantees. Sellers’ termination of Seller Guarantees in accordance with this Section 6(m) shall not constitute a breach of this Agreement and Sellers shall have no Liability to Buyer by reason thereof, including without limitation any Liability relating to termination of any Contract in accordance with its terms, the performance of which is subject to such Seller Guarantees.

At Closing, Buyer will deliver counter guarantees in form and substance reasonably satisfactory to Sellers to be issued by the Lenders or such other financial institutions as are reasonably satisfactory to Sellers in favor of Sellers in respect of any Seller Guarantees not terminated as of the Closing, and Buyer shall cause such counter guarantees to remain in place until such Seller Guarantees are released. Sellers agree that, following the Closing, Sellers will

not modify (except for the termination of such Seller Guarantees in accordance with this Section 6(m)(i)) any such Seller Guarantees while they remain outstanding without Buyer’s prior written consent, which shall not be unreasonably withheld or delayed.

(ii) With respect to the RWE Contract, (A) the Parties shall use their commercially reasonable efforts to obtain prior to the Closing RWE Energie AG’s consent to the assignment of the RWE Contract to Buyer, (B) to the extent that RWE Energie AG conditions the grant of its consent on Buyer obtaining a guarantee or other form of financial assurance, from and after the date of this Agreement Buyer will use its commercially reasonable efforts to obtain such guarantee or form of financial assurance, and (C) if Buyer is unable to obtain RWE Energie AG’s consent, Buyer and Sellers shall enter a lawful arrangement reasonably satisfactory to Buyer and Sellers that enables Buyer to obtain the benefits of and assume the obligations under the RWE Contract as provided in Section 2(a)(v).

(n) Transition Services. From and after the Closing Date until the first anniversary of the Closing Date, each Party shall provide to the other Party such transition services as the other Party reasonably may request, taking into account the services set forth on Schedule 6(n), in a manner and at a level consistent with the historical practices of the Business. During the first six-month period following the Closing, the Party receiving the service shall pay to the Party providing such service on a monthly basis a fee for such service equal to the cost incurred by such Party to provide the service. During the second six-month period following the Closing, the Party receiving the service shall pay to the Party providing such service on a monthly basis a fee for such service equal to 120% of the cost incurred by such Party to provide the service.

With respect to the Company Real Property, Sellers shall take all reasonable actions, at their cost, to terminate that certain hereditary building right in favor of Synthese Gasanlage Ruhr GmbH, Oberhausen, encumbering the Company Real Property (in particular the Company Real Property registered in the land registers of Holten, folio 0071, plot 6, parcels 621 and 622 and land register of Holten, folio 0051, plot 6, parcels 624, 625, 629, 631, 632, 633, 634, 635, 636 and 637) and shall bear all costs or obligations deriving from such termination.

8. Remedies for Breaches of this Agreement.

(a) Survival of Representations and Warranties. The representations and warranties of the Parties made or provided for in this Agreement shall survive the Closing for a period of 30 days following the completion of audited financial statements for the Business for the fiscal period ended December 31, 2007, but in no event later than July 31, 2008; provided, however, that the representations and warranties in Sections 3(a), 3(b), 3(k)(i), 3(k)(ii), 3(n), 4(a) and 4(b) shall survive indefinitely, and the representations and warranties in Section 3(m) shall survive for the period provided in Section 6(e)(xii). The covenants contained in this Agreement shall survive until fully discharged. No Claim for indemnification for breaches of any representation, warranty or covenant may be asserted after the expiration of the applicable survival period set

forth in this Section 8(a). So long as an Indemnified Party asserts a Claim for indemnification under and in accordance with this Section 8 for a breach by another Party of any of its representations, warranties or covenants contained in this Agreement prior to the expiration of the applicable survival period set forth in this Section 8(a), such Indemnified Party shall be deemed to have preserved its rights to indemnification under this Section 8 regardless of when such Claim is ultimately liquidated or resolved. Claims by Sellers relating to Assumed Liabilities may be brought at any time following the Closing.

(b) Indemnification by Sellers. Subject to the provisions of this Section 8, Sellers agree to indemnify, defend and hold harmless the Buyer Indemnified Parties from and after the Closing, against any and all Claims to the extent such Claims are based upon, arise out of or are related to (i) a breach of any representation or warranty of either Seller set forth in this Agreement or any agreement, document or instrument delivered pursuant to this Agreement, (ii) any failure to perform or comply with any of the covenants, conditions or agreements of either Seller set forth in this Agreement or any agreement, document or instrument delivered pursuant to this Agreement; or (iii) any Excluded Liability.

(c) Indemnification by Buyer. Subject to the provisions of this Section 8, Buyer agrees to indemnify, defend and hold harmless each Seller, their respective Affiliates and their respective officers, directors, representatives, agents and employees (the “Seller Indemnified Parties”), from and after the Closing, against any and all Claims to the extent such Claims are based upon, arise out of or are related to (i) a breach of any representation or warranty of Buyer set forth in this Agreement or any agreement, document or instrument delivered pursuant to this Agreement, (ii) any failure to perform or comply with any of the covenants, conditions or agreements of Buyer set forth in this Agreement or any agreement, document or instrument delivered pursuant to this Agreement, or (iii) any Assumed Liabilities.

(d) Indemnification Procedures.

(i) If any third party shall notify any Party (the “Indemnified Party”) with respect to any matter (a “Third Party Claim”) which may give rise to a Claim for indemnification against any other Party (the “Indemnifying Party”) then the Indemnified Party shall promptly (and in any event within ten Business Days after receiving notice of the Third Party Claim) notify each Indemnifying Party thereof in writing. The failure to notify the Indemnifying Party promptly of a Third Party Claim shall not relieve the Indemnifying Party from its indemnification obligation hereunder, except to the extent that the Indemnifying Party is materially prejudiced thereby.

(ii) Any Indemnifying Party will have the right at any time to assume and thereafter conduct the defense of the Third Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Party; provided, however, that the Indemnifying Party shall not waive any defense, cause of action or counterclaim or consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (not to be withheld unreasonably). In the event that the Indemnifying Party assumes the defense as provided in this Section 8(d), the Indemnified Party shall have the

right to participate in such defense (including with counsel of its choice), at its own expense, and the Indemnifying Party shall reasonably cooperate with the Indemnified Party in connection with such participation. In the event that the Indemnified Party shall in good faith determine that the Indemnified Party may have available to it one or more defenses or counterclaims that are inconsistent with one or more of those that may be available to the Indemnifying Party in respect of any Third Party Claim or any litigation relating thereto, the Indemnified Party shall have the right at all times to take over and assume control over the defense, settlement, negotiations or litigation relating to any such Third Party Claim at the sole cost of the Indemnifying Party; provided, however, that if the Indemnified Party does so take over and assume control, the Indemnified Party shall not consent to the entry of any judgment or enter into a settlement with respect to such Third Party Claim without the prior written consent of the Indemnifying Party (not to be withheld unreasonably).

(iii) Unless and until an Indemnifying Party assumes the defense of the Third Party Claim as provided in Section 8(d)(ii) above, however, the Indemnified Party may defend against the Third Party Claim in any manner it reasonably may deem appropriate, on behalf of and for the risk of the Indemnifying Party and the Indemnifying Party shall be liable for the reasonable fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense thereof.

(iv) In no event will the Indemnified Party consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (not to be withheld unreasonably).

(v) The Party assuming the defense under this Section 8(d) shall keep the appropriate Parties reasonably informed regarding the progress and status thereof.

(vi) In the event any Indemnified Party should have a Claim against any Indemnifying Party hereunder which does not involve a Third Party Claim, the Indemnified Party shall promptly transmit to the Indemnifying Party a written notice (the “Indemnity Notice”) describing in reasonable detail the nature of the Claim and the basis of the Indemnified Party’s request for indemnification under this Agreement, provided, however, that failure of the Indemnified Party to give the Indemnity Notice will not relieve the Indemnifying Party from liability hereunder unless and solely to the extent that the Indemnifying Party did not otherwise learn of such Claim and such failure results in the forfeiture by the Indemnifying Party of substantial rights and defenses, and will not in any event relieve the Indemnifying Party from any obligations to the Indemnified Party other than the indemnification obligation provided herein. In the event that the Indemnifying Party disputes the validity or scope of the Claim set forth in the Indemnity Notice, the parties will use their good faith efforts to resolve such matter within 30 days of receipt of the Indemnity Notice. If the dispute is not resolved during such 30-day period, such matter shall be resolved in accordance with Section 11(h).

(e) Limitations. The amount of any Claim indemnifiable by an Indemnifying Party pursuant to this Section 8 shall be reduced by the amount of any insurance proceeds resulting from the subject matter of such Claim actually received by the Indemnified Party in respect of

such Claim (net of any resulting increase in insurance premiums and any expenditures made in connection with obtaining such insurance recovery). Sellers shall not be required to indemnify Buyer under Section 8(b)(i) with respect to any Claims, and Buyer shall not be required to indemnify Sellers under Section 8(c)(i) with respect to any Claims, until the aggregate amount of all such Claims against Seller, or against Buyer, as the case may be, exceeds an amount equal to €5,000,000 (the “Indemnification Threshold”), in which case the Indemnifying Party shall only be liable for the amount of all Claims in excess of the Indemnification Threshold. Sellers’ aggregate liability to Buyer, and Buyer’s aggregate liability to Sellers, for Claims arising from this Agreement under Section 8(b)(i) or Section 8(c)(i) each shall be limited to an amount equal to €50,000,000 (the “Indemnification Cap”). Notwithstanding anything to the contrary in this Section 8, in no event shall Buyer or Sellers be entitled to indemnification under Section 8(b)(i) or Section 8(c)(i) with respect to any individual Claim arising out of a breach of any representation or warranty other than the representations and warranties set forth in Section 3(o) unless the amount of the individual Claim for which indemnification is being sought by such Party exceeds €20,000 (without regard to any materiality qualifiers in such representation or warranty), but any such otherwise indemnifiable Claim that does not exceed €20,000 shall not be taken into account in calculating whether the Indemnification Threshold has been satisfied. Notwithstanding the foregoing, breaches of representations and warranties in Sections 3(a), 3(b), 3(k)(i), 3(k)(ii), 3(m), 3(n), 4(a) and 4(b) shall not be subject to the Indemnification Threshold or Indemnification Cap. By way of clarification, with respect to any Claims arising out of a matter that constitutes both a breach of a representation or warranty and an Excluded Liability, such Claims shall be treated as an Excluded Liability and Sellers’ indemnification obligation hereunder shall not require Sellers to indemnify the Buyer Indemnified Parties against the same Claims twice.

(f) Duty to Mitigate. The Indemnified Party will use commercially reasonable efforts to mitigate all Claims, including availing itself of any defenses, limitations, and other rights at law or equity to the extent the Indemnified Party is in control of such defense, but the Indemnified Party shall not be required to commence litigation against any third party or incur any unreasonable expenses to mitigate such Claim. Should the Indemnified Party incur expenses in connection with such mitigation, the Indemnifying Party shall reimburse the Indemnified Party for the Indemnified Party’s reasonable expenditures in undertaking the mitigation.

(g) Exclusive Remedy. After the Closing, the remedies provided for in this Section 8 shall be exclusive and shall be in lieu of all remedies for any other matters arising in connection with or relating to the transactions contemplated by this Agreement, including, but not limited to, any breach of any representation, warranty, covenant or other provision of this Agreement (other than any breach that was fraudulent or intentional); provided, however, that this sentence shall not be deemed a waiver by any Party of any right to specific performance or injunctive relief under Section 11(m). Without limiting the generality of the foregoing, to the extent the transfer, conveyance, assignment and delivery of Purchased Assets to Buyer as provided in this Agreement is accomplished by deeds, assignments, easements, leases, licenses, bills of sale or other instruments of transfer and conveyance, whether executed at the Closing or thereafter, these instruments are made without representation or warranty by, or recourse against, Sellers, except as expressly provided in this Agreement or in any such instrument.

9. Environmental Indemnity.

(a) Indemnification by Sellers. Notwithstanding anything to the contrary herein, Sellers agree to indemnify, defend and hold harmless the Buyer Indemnified Parties from and after the Closing, against any and all Claims or Liabilities to the extent and in the proportion based upon, arising out of or related to:

(i) Environmental Conditions which (a) are known as of the Closing, or (b) are associated with Hazardous Substances present or Released at the Facilities prior to the Closing but no longer used by the Business as of the Closing, including the Hazardous Substances being investigated and/or remediated as of the Closing (collectively “Historic Use Contamination”), including any third-party claim for loss of life, or injury to persons or property to the extent caused (or allegedly caused) by the Historic Use Contamination;

(ii) Environmental Conditions which are unknown as of the Closing and relate to Hazardous Substances present or Released at the Facilities on or prior to the Closing, and still used by the Business as of the Closing (“Pre-Closing Business Related Contamination”), including any third-party claim for loss of life, or injury to persons or property to the extent caused (or allegedly caused) by the Pre-Closing Business Related Contamination, but only to the extent of Sellers’ applicable cost-sharing percentage as described in Section 9(e); and

(iii) Environmental Conditions at any real property not included in the Facilities, which was either (x) owned, operated, leased or used by the Companies or Sellers for the Business (“Former Sites”) or (y) used by the Companies or Sellers with respect to the Business for the off-site disposal or treatment of Hazardous Substances (“Disposal Sites”) on or prior to the Closing Date (collectively “Excluded Environmental Liabilities”), including any third-party claim for loss of life, or injury to persons or property to the extent caused (or allegedly caused) by Excluded Environmental Liabilities; and

(b) Indemnification by Buyer. Notwithstanding anything to the contrary herein, Buyer agrees to indemnify, defend and hold harmless the Seller Indemnified Parties from and after the Closing, against any and all Claims or Liabilities to the extent and in the proportion based upon, arising out of or related to:

(i) Pre-Closing Business Related Contamination, but only to the extent of Buyer’s applicable cost-sharing percentage as described in Section 9(e);

(ii) Environmental Conditions associated with Hazardous Substances Released at the Facilities after the Closing, including any third-party claim for loss of life, or injury to persons or property to the extent caused (or allegedly caused) by such Environmental Conditions or Release; and

(iii) Any violation of the terms and conditions of any Environmental Permit or any portion thereof applicable to the Purchased Assets until such Environmental Permits are transferred or reissued to Buyer or Buyer Indemnified Party.

(c) Survival. Sellers shall be liable for any claim for indemnification for Liabilities or Claims hereunder only to the extent written notice of a claim is given on or before (x) the 15th anniversary of the Closing in the case of relating to Pre-Closing Business-Related Contamination at any Facility, and (y) indefinitely with respect to Excluded Environmental Liabilities and Historic Use Contamination. So long as a Buyer Indemnified Party asserts a Claim for indemnification under and in accordance with this Section 9(c) prior to the expiration of the applicable survival period set forth in this Section, such Indemnified Party shall be deemed to have preserved its rights to indemnification under this Section 9(c) regardless of when such Claim is ultimately liquidated or resolved.

(d) Limitations on Duty to Indemnify.

(i) To the extent acceptable to the Governmental Entities with jurisdiction over the investigation or remediation of any Historic Use Contamination or Pre-Closing Business Related Contamination, Buyer Indemnified Parties shall agree to the Sellers’ use of risk-based cleanup standards appropriate for commercial and industrial sites to conduct Remediation and achieve closure, including where appropriate deed restrictions and engineering controls, provided such standards and restrictions do not unreasonably interfere with the operations of the Business or impose any material undertakings or obligations on the Business or require the Business to obtain any new Permits. Without limiting the foregoing, Sellers may elect to perform or have performed the least costly Remediation allowed by Environmental Law and acceptable to the relevant Governmental Entity, which is also reasonable in terms of the protection of the environment, health and safety.

(ii) With respect to any Historic Use Contamination or Pre-Closing Business Related Contamination, Sellers shall have no obligation to indemnify Buyer Indemnified Parties hereunder for any Liabilities or Claims that result from: (A) any Buyer Indemnified Party undertaking any testing, drilling or sampling of the Environment other than (1) as required by or necessary to achieve compliance with applicable Environmental Law or as required by an order or directive of a Governmental Entity or by an applicable Permit, or (2) as may be determined by Buyer in the exercise of its commercially reasonable judgment to be necessary to (x) avoid or eliminate a serious and current risk to human health or safety or the Environment or (y) respond to a pending or threatened claim; (3) to carry out and in conjunction with a bona fide construction, renovation or demolition project or emergency repair; or (4) with Sellers approval; or (B) any notification, report, admission or disclosure of any pre-closing condition by Buyer to any Governmental Entities except to the extent (1) required by Environmental Laws, Permits or any Order of a Governmental Entity or (2) agreed to in writing by Sellers or (3) made in response to an emergency incident or other exigent circumstance at a Facility, or (c) any Buyer Indemnified Party voluntarily undertakes Remediation not required by or necessary to achieve compliance with Environmental Law other than in conjunction with a bona fide construction, renovation or demolition project or emergency repair or in response to an emergency incident or other exigent circumstances at a Facility.

(iii) With respect to the Historic Use Contamination or Pre-Closing Business Related Contamination, Sellers shall have no obligation to indemnify Buyer Indemnified Parties

hereunder for any of the increased Liabilities or Claims that arise directly from the gross negligence or willful misconduct of any Buyer Indemnified Party or any successor in title to the Business or the Companies or the related assets; provided, this is limited to the increased costs caused by such conduct.

(iv) By way of clarification, with respect to any Claims or Liabilities arising out of a matter that constitutes both a breach of a representation or warranty and an Excluded Environmental Liability, such Claims or Liabilities shall be treated as an Excluded Environmental Liability and Sellers’ indemnification obligation hereunder shall not require Sellers to indemnify the Buyer against the same Claims and Liabilities twice.

(v) Buyer shall promptly notify Sellers following Buyer obtaining actual knowledge of any intent by a Governmental Entity to amend, modify or otherwise require terms and conditions in an Environmental Permit which contains or may reasonably lead to such Permit containing a requirement for Remediation for which Sellers would be solely liable and, to the extent reasonably practical, allow and cause each affiliated Buyer to allow Sellers and their representatives to attend and participate in any discussions, site visits or meetings and to comment in advance (and to have comments reasonably taken into account) on any material filings with respect to such Environmental Permits; provided that Buyer shall have no obligation to take any position that would in Buyer’s reasonable opinion would be expected to impose materially greater obligations on Buyer than would be imposed without taking into account Sellers indemnity obligations hereunder. Neither Buyer nor any Buyer Indemnified Party shall knowingly or intentionally offer or suggest that an Environmental Permit contain any condition or provision requiring Remediation for which Sellers would be liable under Section 9, in any correspondence or discussions with any Governmental Entity except with the consent of Sellers, which consent shall not be unreasonably withheld; provided, however, that nothing herein shall prevent Buyer Indemnified Parties from agreeing to such a condition if raised or imposed by the Governmental Entity.

(vi) Remediation Derived Wastewater. With respect to sites on which Buyer or any Buyer Indemnified Party operates a wastewater treatment plant, which plant has excess capacity, Buyer agrees to accept at no charge to Sellers, any water or recovered groundwater produced in the course of a Seller-controlled Remediation, to the extent accepting such waters is allowed by Environmental Laws, including Buyer’s willingness to use commercially reasonable efforts to seek modification or amendments to any relevant Permit so that it can accept such waters; provided, Buyer shall not be required to modify or make any capital improvements to its wastewater treatment plant; provided, further, Buyer shall have the right to impose a reasonable fee for such services (such fee to be consistent with the methodology in the applicable U.S. or German Site Services Agreement); if the costs are more than incidental to Buyer’s operations or otherwise raises capacity issues for Buyer. Sellers shall indemnify Buyer Indemnified Parties for costs associated with any disposal of waters, which are incompatible with Buyer’s wastewater treatment plant. Should Buyer-controlled Remediation occur at Sellers’ Bishop, Texas site, the provisions of this Section 9(d)(vi) shall apply with the term “Buyer” replaced by “Sellers” and the term “Seller” or “Sellers” replaced by “Buyer.”

*** The confidential portions of this exhibit have been filed separately with the Securities and Exchange Commission pursuant to a confidential treatment request in accordance with Rule 24b-2 of the Securities and Exchange Act of 1934, as amended. The location of each omitted portion is indicated by a series of three asterisks in brackets (“[***]”).

(vii) Remediation Derived-Soil Disposal. Where nonhazardous contaminated soil or nonhazardous waste are generated in the course of Sellers-controlled Remediation, Buyer agrees that Sellers shall have the right to construct new landfills on-site to accept such wastes, which landfills shall be constructed in an area approved by Buyer, which approval shall not be unreasonably withheld, denied or conditioned, and in compliance with applicable laws, including Environmental Laws. Buyer agrees that Buyer and Buyer Indemnified Parties shall cooperate with Sellers in the construction of the landfill, including, if required by Environmental Laws obtaining new Permits in the name of Buyer or the relevant Buyer Indemnified Party to construct new on-site landfills to accept such wastes. Sellers shall indemnify the Buyer Indemnified Parties for (a) reasonable, third-party costs, expenses or capital expenditures incurred in the implementation of this paragraph and (b) any Claims or Liabilities asserted against or imposed on Buyer Indemnified Parties as a result of such Seller-controlled landfills. Should Buyer-controlled Remediation occur at Sellers’ Bishop, Texas site, the provisions of this Section 9(d)(vii) shall apply with the term “Buyer” replaced by “Seller” and the term “Seller” or “Sellers” replaced by “Buyer.”

(viii) With respect only to [***] [***] [***] [***] [***] [***], prior to seeking recovery of a claim against Sellers under this Article 9, Buyer shall use commercially reasonable efforts to pursue such matter against [***] [***] [***] [***] [***] [***] [***] [***] [***] [***], including pursuing claims pursuant to [***] [***] [***] [***] [***] [***] [***] [***] [***] [***], provided Buyer shall not be required to commence litigation against [***], except as provided in the penultimate sentence of this paragraph 9(d)(viii). While pursuing a claim against [***] [***] [***] [***], Buyer shall keep Sellers reasonably informed of the progress of such claim and consult in good faith with Sellers. Prior to settling or compromising such a claim, Buyers shall seek Sellers’ approval, which shall not be unreasonably withheld. Should Buyer’s efforts fail to enforce such a claim, Buyer shall, to the extent legally permissible, assign its relevant rights pursuant to such contract between [***] [***] [***] to Sellers or, if not legally permissible, shall exercise such rights at Sellers’ direction, benefit and cost. Sellers shall reimburse Buyer for (a) all reasonable out-of-pocket costs and expenses incurred in enforcing such rights unless such costs are recovered from [***] [***] [***] and (b) the shortfall in any settlement or compromise reached with [***] [***] [***] under this paragraph.

(e) Cost-Sharing. With respect to Pre-Closing Business-Related Contamination or breaches of Section 3(i), the Parties agree to allocate the Claims and Liabilities based on the following formula:


For Claims Made:	Sellers’ Percentage			Buyer’s Percentage

On or before the First Anniversary of the Closing		100	%		0	%

After the Third Anniversary of the Closing but on or before the Fourth Anniversary of the Closing		80	%		20	%

After the Fourth Anniversary of the Closing but on or before the Fifth Anniversary of the Closing		73	%		27	%

After the Twelfth Anniversary of the Closing but on or before the Thirteenth Anniversary of the Closing		20	%		80	%

After the Thirteenth Anniversary of the Closing but on or before the Fourteenth Anniversary of the Closing		13	%		87	%

After the Fourteenth Anniversary of the Closing but on or before the Fifteenth Anniversary of the Closing		6	%		94	%

After the Fifteenth Anniversary of the Closing		0	%		100	%

For the sake of clarity, this Cost-Sharing Formula shall not apply to Excluded Environmental Liabilities or Historic Use Contamination.

(f) Procedures.

(i) Remediation. Sellers shall control any Remediation governed by this Section 9; provided, that with respect to Pre-Closing Business Related Contamination, the Party with the higher cost-sharing percentage at the time the Claim for such Pre-Closing Business Related Contamination is filed shall control the Remediation with respect to such Claim; provided, further, that with respect to any Remediation of any Environmental Condition at the Facilities, the Party that is not controlling the Remediation may monitor and participate in discussions with respect to such Remediation at its sole cost and expense; and provided, further, that prior to commencing any Remediation at a Buyer Facility, Sellers shall notify Buyer of its intent to undertake Remediation and shall provide Buyer with a reasonable opportunity to review and comment on any proposed plans or reports, work plans or other reports or documents associated with Remediation and shall make a reasonable effort to incorporate any reasonable comments by Buyer on such plans, reports or other documents. Buyer shall use commercially reasonable efforts to assist Sellers in its obligations hereunder, including providing reasonable access to the Facilities and Sellers agree to (i) not allow its activities to unreasonably interfere with the operation of the Business, except to the extent required in order to comply with applicable law, (ii) use environmental professionals reasonably acceptable to Buyer, possessing

reasonable levels of insurance, taking into account the nature of the project, and which name Buyer Indemnified Parties as additional insureds, (iii) coordinate access with Buyer and to provide reasonable advance notice when Seller or its consultants will be undertaking work at a Buyer Facility.

(ii) Third-Party Claims for Damages. Claims made pursuant to this Section 9 not involving Remediation at a Buyer Facility shall be governed by the procedures set forth in Section 8(d).

(g) Assignment. Notwithstanding anything to the contrary herein, Buyer shall have the right, upon the sale of any Facilities, to assign with the specific indemnity the rights and benefits provided in Section 9(a) with respect to that specific Facility to the new owner and, with Sellers’ approval, which approval shall not be unreasonably withheld, delayed or conditioned, shall have the right to assign its obligations with respect to the Facility being transferred to the new owner.

(h) Exclusive Remedy. After the Closing, the remedies provided for in this Section 9 shall be exclusive and shall be in lieu of all other remedies for any matters to which this Section 9 applies; provided, however, that this sentence shall not be deemed a waiver by any Party of any right to specific performance or injunctive relief under Section 11(m).

10. Termination.

(a) Termination of Agreement. The Parties may terminate this Agreement as provided below:

(i) Buyer and Sellers may terminate this Agreement by mutual written consent at any time prior to the Closing;

(ii) Buyer or Sellers may terminate this Agreement if any Governmental Entity shall have enacted, promulgated or issued any statute, rule, regulation, ruling, writ or injunction, or taken any other action, restraining, enjoining or otherwise prohibiting the transactions contemplated hereby and all appeals and means of appeal therefrom have been exhausted;

(iii) Buyer may terminate this Agreement by giving written notice to Sellers at any time prior to the Closing (A) if any Seller has breached any representation, warranty or covenant contained in this Agreement, such breach would result in the Closing condition set forth in Section 7(a)(i) or (ii) not being met, Buyer has notified Sellers of the breach in writing, and the breach has continued without cure for a period of 30 days after written notice of breach or is incapable of being cured, or (B) if the Closing shall not have occurred on or before June 30, 2007, by reason of the failure of any condition precedent under Section 7(a) hereof (unless the failure results primarily from Buyer itself materially breaching any representation, warranty or covenant contained in this Agreement); and

(iv) Sellers may terminate this Agreement by giving written notice to Buyer at any time prior to the Closing (A) if Buyer has breached any representation, warranty or covenant contained in this Agreement, such breach would result in the Closing condition set forth in Section 7(b)(i) or (ii) not being met, Sellers have notified Buyer of the breach in writing, and the breach has continued without cure for a period of 30 days after written notice of breach or is incapable of being cured, or (B) if the Closing shall not have occurred on or before June 30, 2007, by reason of the failure of any condition precedent under Section 7(b) hereof (unless the failure results primarily from either Seller materially breaching any representation, warranty or covenant contained in this Agreement).

(b) Effect of Termination. If any Party terminates this Agreement pursuant to Section 10(a) above, all rights and obligations of the Parties hereunder shall terminate without any liability of any Party to any other Party (except for any liability of a Party then in breach); provided, however, that the Confidentiality Agreement and the provisions of this Section 10(b) and Section 10 shall survive any termination of this Agreement in accordance with their terms.

11. Miscellaneous.

(a) Press Releases and Public Announcements. Except as required by applicable law or the rules of any applicable stock exchange, in each case as set forth in a reasonable written opinion of legal counsel to a Party, no Party shall issue any press release or make any public announcement relating to the subject matter of this Agreement prior to the Closing without the prior written approval of the other Parties.

(b) No Third-Party Beneficiaries. Except as provided in Sections 8(b), 8(c), and 9(a), this Agreement shall not confer any rights or remedies upon any Person other than the Parties and their respective successors and permitted assigns, and nothing contained herein, express or implied, is intended to or shall confer upon any other Person any third-party beneficiary right or any other legal or equitable rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement other than any Person entitled to indemnification under Section 8(b), Section 8(c) or Section 9.

(c) Entire Agreement.

(d) Succession and Assignment. This Agreement shall be binding upon and inure to the benefit of the Parties named herein and their respective successors and permitted assigns. No Party may assign either this Agreement or any of its rights, interest or obligations hereunder without the prior written approval of the other Parties; provided, however, that a Party may assign any of its rights or obligations under this Agreement to any of its Affiliates upon written notice to the other Parties, but such assignment shall not constitute a release of the assigning Party, which shall remain responsible for performing any assigned obligation in the event the assignee fails to perform such obligation. Buyer, Parent and Sellers also may assign this

Agreement in whole or part by way of security to any bank or other financial institution on behalf of itself or other creditors for the purpose of securing any obligations under banking or other financings made or proposed to be made available to Buyer, Parent, any Seller or any Affiliate thereof. Any purported assignment or delegation in violation of this Section 11(d) shall be null and void.

(e) Counterparts. This Agreement may be executed in one or more counterparts (including by means of facsimile), each of which shall be deemed an original but all of which together will constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by facsimile shall be effective as delivery of an originally executed counterpart to this Agreement.

(f) Headings. The section headings contained in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement.

(g) Notices.

(h) Governing Law; Arbitration.

(i) This Agreement shall be governed by and construed and interpreted in accordance with the substantive laws of the State of New York, without giving effect to any choice of law or conflicts of law provision that would cause the application of the laws of a jurisdiction other than New York; provided that the transfer of shares, partnership interests, real estate and other assets shall be governed by the law that mandatorily applies thereto.

(ii) Any disputes, controversies or Claims arising out of or in connection with this Agreement, including any question regarding its existence, validity or expiration but

excluding specific performance or injunctive relief sought under Section 11(m), shall be finally and completely resolved without appeal by arbitration under the International Arbitration Rules of the American Arbitration Association (“AAA Rules”) in force at the date of the request for arbitration, which AAA Rules are deemed to be incorporated by reference into this clause; provided, however, that in the event of any conflict between such rules and the other provisions of this Agreement, such other provisions of this Agreement shall control. The arbitral tribunal shall consist of three arbitrators, each of which shall be fluent in English. Each of Buyer, on the one hand, and Sellers, on the other hand, shall appoint one arbitrator. If either Buyer or Sellers fails to appoint an arbitrator within 30 days of receiving notice of an appointment of an arbitrator by the other Party, such arbitrator shall at the request of either Buyer or Sellers be appointed by the President of the American Arbitration Association. The two arbitrators so appointed shall, within 30 days of the date of the appointment of the second arbitrator, appoint a third arbitrator who shall act as the chairman of the tribunal. If the two arbitrators to be appointed fail to agree upon a third arbitrator within 30 days of the appointment of the second arbitrator, then the third arbitrator shall be appointed by the President of the American Arbitration Association at the written request of either Buyer or Sellers. The arbitration proceedings shall take place in New York, New York and the language of such proceedings, including arguments and briefs, shall be English. Each party shall be entitled to reasonable discovery rights, and issues as to discovery shall be determined by the arbitral panel applying to the laws of New York without regard to principles of conflicts of laws. The award of the arbitrators shall be by majority vote and shall be in writing, shall set forth the facts found by the arbitrators to exist, their determination and the basis of their determination. Any award shall be made in US dollars. Notwithstanding any provision of this Agreement which may be interpreted to the contrary, the arbitral tribunal shall not have the authority to award consequential or punitive damages. Each Party shall bear its own attorneys’ fees and expenses. The fees and expenses for the arbitral panel shall be borne on a 50/50 basis by Buyer and Sellers. The award of the arbitral tribunal shall be final and not subject to appeal and judgment upon the award may be entered in any competent court.

(i) Amendments and Waivers. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by each Buyer and Sellers, and appropriately notarized to the extent required by applicable law. No waiver by any Party of any provision of this Agreement or any default, misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, shall be valid unless the same shall be in writing and signed by the Party making such waiver, nor shall such waiver be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence.

(j) Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.

(k) Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the Parties and no presumption or burden of

proof shall arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement. Any reference to any federal, state or local or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated thereunder, unless the context requires otherwise. The word “including” shall mean including without limitation. The words “historical accounting methods” means the accounting methods and practices historically used by the applicable Seller or Company, which (i) in the case of Sellers, Titan GmbH and Infraserv Oberhausen, are in accordance with accounting principles generally accepted in the United States, and (ii) in the case of Eoxo, are in accordance with accounting principles generally accepted in Germany.

(l) Incorporation of Exhibits, Annexes, and Schedules. The Exhibits and Schedules identified in this Agreement are incorporated herein by reference and made a part hereof.

(m) Specific Performance. Each Party acknowledges and agrees that the other Parties would be irreparably injured if any of the provisions of this Agreement are not performed in accordance with their specific terms and that money damages may not or would not be an adequate remedy in such event. Therefore, the non-breaching Party may be entitled to specific performance of this Agreement and injunctive or other equitable relief to prevent breaches of this Agreement and to specifically enforce the provisions hereof. Each Party agrees to waive any requirement for the securing or posting of any bond in connection with any such remedy. For purposes of any action for specific performance of this Agreement or other injunctive or equitable relief, each Party irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the U.S. federal courts situated in the Southern District of New York, and the Parties hereto hereby irrevocably submit to the exclusive jurisdiction of such courts in such event. Each Party, to the extent permitted by applicable law, hereby waives and agrees not to assert, by way of motion, as a defense or otherwise, in any such suit, action or proceeding brought in such courts, any claim that it is not subject personally to the jurisdiction of such courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court. Each Party consents to the service of process in any suit, action or proceeding by the mailing of copies thereof to such Party at any time at its address to which notices are to be given pursuant to Section 11(g). Each Party agrees that its submission to jurisdiction and consent to service of process by mail is made for the express benefit of the other Parties. Final judgment against any Party in any such suit, action or proceeding shall be conclusive, and may be enforced in any other jurisdiction (i) by suit, action or proceeding on the judgment, a certified or true copy of which shall be conclusive evidence of the fact and the amount of liability of the party therein described or (ii) in any other manner provided by or pursuant to the laws of such other jurisdiction.

(n) Limitation on Damages. Absent fraud, no Party shall be liable to another Party for any consequential, incidental, special, punitive or exemplary damages or lost profits suffered by such other Party due to a Party’s breach of any of its representations, warranties or covenants hereunder.

(o) Bulk Transfer Laws. Without admitting the applicability of the bulk transfer laws of any jurisdiction, the Parties agree that they will not comply with any applicable bulk transfer or similar law in connection with the transactions contemplated by this Agreement; provided, however, that the applicable Seller agrees (i) to pay and discharge when due or to contest or litigate all claims of creditors which are asserted against Buyer or the Purchased Assets by reason of such noncompliance, and (ii) to indemnify, defend and hold harmless Buyer from and against any and all such claims.

(p) Parent Guarantee. Parent hereby agrees to guarantee, and be jointly and severally liable for, the due and punctual performance of each and every obligation of each Seller and its successors and assigns under this Agreement, including ensuring that German Seller will transfer the Seller Real Property, Acquired Share Interests and Ancillary Shares and all other Purchased Assets to be transferred hereunder.

IN WITNESS WHEREOF, the Parties have executed this Agreement as of the date first above written.
