Section 3.1. Purchase Price. The aggregate purchase price for the Purchased Assets shall be equal to $227,658,000 in cash minus the amount of (i) the interest-bearing debt and capitalized leases on the books of Sellers (including amounts for buy-outs at the end of the lease term), if any, and (ii) remaining payments under operating leases of production equipment providing for annual lease payments in excess of $100,000 (including amounts for buy-outs at the end of the lease term), if any, which leases, in the case of (i) or (ii), are being assumed by Buyer pursuant to Section 2.3(a) (the "Closing Purchase Price"), subject to adjustment following the Closing in accordance with Section 3.2 (the "Final Purchase Price"). The Closing Purchase Price shall be paid by Buyer pursuant to Section 4.2 hereof. The Closing Purchase Price may also be adjusted pursuant to Section 3.5.

Section 3.2. Purchase Price Adjustment. (a) As soon as practicable, but in no event later than 60 days following the Valuation Date, Sellers shall prepare a statement of adjusted working capital of the Business as of the Valuation Date (including the notes thereto, the "Valuation Date Statement"). The Valuation Date Statement shall present the net amount of the current assets of the Business that are Purchased Assets less the current liabilities of the Business that are Assumed Liabilities plus, from the Financial Statements Date to the Valuation Date, the investment in fixed assets (other than investments resulting from the purchase of (A) assets subject to capitalized leases on the books of Sellers or (B) production equipment under operating leases) less (i) the net proceeds from the disposal of any fixed assets of the Business and (ii) the replacement cost of any fixed assets of the Business included in the Purchased Assets that, from the Financial Statements Date to the Valuation Date, are lost, damaged beyond repair or destroyed (the "Net Working Capital Amount") and shall be prepared with respect to such items on a basis consistent with the Financial Statements. Notwithstanding the foregoing, the Valuation Date Statement shall not include any interest-bearing debt, any capitalized lease on the books of Sellers or any operating lease of production equipment providing for annual lease payments in excess of $100,000.

(b) During the preparation of the Valuation Date Statement and the period of any dispute within the contemplation of this Section 3.2, Buyer shall (i) provide Sellers and Sellers' authorized representatives with access to the books, records, facilities, employees and accountants of the Business,

(ii) provide Sellers as promptly as practicable after the Closing Date (but in no event later than 30 days after the Closing Date) with normal month-end closing financial information for the period ending on the Valuation Date and (iii) cooperate with Sellers and Sellers' authorized representatives, including the provision on a timely basis of all information necessary or useful in connection with Sellers' preparation of the Valuation Date Statement.

(c) Sellers shall deliver a copy of the Valuation Date Statement, together with the work papers used in the preparation thereof, to Buyer promptly after it has been prepared and in no event later than 60 days after the Closing Date. After receipt of the Valuation Date Statement, Buyer shall have 60 days to review the Valuation Date Statement, together with the work papers used in the preparation thereof. Unless Buyer delivers written notice to Sellers on or prior to the 60th day after Buyer's receipt of the Valuation Date Statement specifying all disputed items and the basis therefor, Buyer shall be deemed to have accepted and agreed to the Valuation Date Statement. If Buyer so notifies Sellers of its objection to the Valuation Date Statement, Sellers and Buyer shall, within 30 days following such notice (the "Resolution Period"), attempt to resolve their differences and any resolution by them as to any disputed amounts shall be final, binding and conclusive.

(d) At the conclusion of the Resolution Period, all amounts remaining in dispute shall be submitted to Deloitte & Touche (the "Neutral Auditors"). In the event that Deloitte & Touche is unwilling to serve as the Neutral Auditor hereunder and Buyer and Sellers are unable to agree on a substitute therefor, Buyer or Sellers may request the American Arbitration Association to appoint a nationally recognized accounting firm to act as Neutral Auditor hereunder who shall not have had a material relationship with Sellers or Buyer or any of their Affiliates within the past two years. Each party agrees to execute, if requested by the Neutral Auditors, a reasonable engagement letter. All fees and expenses relating to the work, if any, to be performed by the Neutral Auditors shall be borne equally by Sellers and Buyer. The Neutral Auditors shall act as an arbitrator to determine, based solely on presentations by Sellers and Buyer, and not by independent review, only those issues still in dispute. The Neutral Auditors' determination shall be made within 30 days of their selection, whether or not such presentations by Sellers and Buyer have been made within such period, and shall be set forth in a written statement delivered to Sellers and Buyer and shall be final, binding and conclusive. The term "Adjusted Valuation Date Statement," as hereinafter used, shall mean the definitive Valuation Date Statement agreed to by Buyer and Sellers in accordance with Section 3.2(c) or the definitive Valuation Date Statement resulting from the determinations made by the Neutral Auditors in accordance with this Section 3.2(d) (in addition to those items theretofore agreed to by Sellers and Buyer), in each case prepared in the manner set forth in the Section 3.2(a) hereof. The Net Working Capital Amount reflected on the Adjusted Valuation Date Statement shall not be less than that specified by Buyer in its notice to Sellers pursuant to subsection (c) above nor more than that specified by Sellers on the Valuation Date Statement.

(e) The Closing Purchase Price shall be increased or decreased, as the case may be, dollar for dollar, to the extent the Net Working Capital Amount reflected in the Adjusted Valuation Date Statement is greater than or less than $7,304,000, as the case may be. The amount of any increase to or reduction of the Closing Purchase Price pursuant to this Section 3.2 shall bear interest from the Closing Date through the date of payment at the Agreed Rate in effect from time to time from the Closing Date to the date of such payment. The amount of any reduction of the Closing Purchase Price pursuant to this Section 3.2(e), together with interest thereon, shall be paid by wire transfer in immediately available funds by the Escrow Agent from the Escrow Account to the account specified by Buyer pursuant to the terms of the Escrow Agreement, and the balance of the Escrow Fund, if any, shall be paid by the Escrow Agent to the account specified by Sellers pursuant to the Escrow Agreement. If the Escrow Fund is insufficient to pay Buyer the amount of the reduction of the Closing Purchase Price pursuant to this Section 3.2(e), then the balance of such reduction of the Closing Purchase Price shall be paid by wire transfer in immediately available funds by Sellers to the account

specified by Buyer. The amount of any increase to the Closing Purchase Price pursuant to this Section 3.2(e), together with interest thereon, shall be paid by wire transfer in immediately available funds by Buyer to the account specified by Sellers. In the event of any increase in the Closing Purchase Price pursuant to this Section 3.2(e), then the Escrow Fund shall be paid by the Escrow Agent to the account specified by Sellers pursuant to the Escrow Agreement. Such payment or transfer, as the case may be, shall be made within five business days after the Adjusted Valuation Date Statement is agreed to by Buyer and Sellers or any remaining disputed items are ultimately determined by the Neutral Auditors.

Section 3.3. Allocation of Purchase Price. Prior to the date hereof, the parties have jointly prepared a schedule (the "Allocation Schedule") allocating the Closing Purchase Price as determined pursuant to Sections 3.1 (including, for purposes of this Section 3.3, any other consideration paid to Sellers, including the Assumed Liabilities) among the Purchased Assets. The Allocation Schedule has been prepared in accordance with Section 1060 of the Code and the regulations thereunder. Buyer and the Sellers each agree to file Internal Revenue Service ("IRS") Form 8594, and all federal, state, local and foreign Tax Returns, in accordance with the Allocation Schedule. Buyer and the Sellers each agree to provide the other promptly with any other information required to complete Form 8594.

Section 3.4. Escrow. At the Closing Date, an escrow account (the "Escrow Account") shall be established with the Norwest Bank Minnesota, N.A. (the "Escrow Agent") for the Escrow Amount in lieu of being paid directly to the Sellers. The Escrow Account shall be established pursuant to an agreement among the parties hereto and the Escrow Agent in substantially the form attached hereto as Exhibit I (the "Escrow Agreement"). At the Closing Date, the Sellers shall be deemed to have directed Buyer to wire transfer to the Escrow Agent an amount equal to the Escrow Amount. The Escrow Amount so delivered to the Escrow Agent and any other property or cash, and any income earned with respect thereto, from time to time held by the Escrow Agent pursuant to the terms of the Escrow Agreement is herein referred to as the "Escrow Fund." The Escrow Fund shall be held by the Escrow Agent in escrow subject to the terms and conditions of the Escrow Agreement and shall apply to the purchase price adjustment set forth in Section 3.2 hereof.

ARTICLE VIII
ADDITIONAL AGREEMENTS

Section 8.1. Use of Names. (a) Sellers are not conveying ownership rights or granting Buyer or its Affiliates (including Newco Brazil after the Closing) a license to use any of the tradenames or trademarks of Sellers or any Affiliate of Sellers, including the "Viskase" trademark (other than as provided in Section 8.1(b) and the Trademarks identified on Schedule 5.11(a)) and, after the Closing, Buyer and its Affiliates (including Newco Brazil after the Closing) shall not use in any manner such names or marks of Sellers or any Affiliate of Sellers or any word that is similar in sound or appearance to such names or marks. In the event Buyer or any Affiliate of Buyer violates any of its obligations under this Section 8.1, Sellers and their Affiliates may proceed against it in law or in equity for such damages or other relief as a court may deem appropriate. Buyer acknowledges that a violation of this Section 8.1 may cause Sellers and their Affiliates irreparable harm which may not be adequately compensated for by money damages. Buyer therefore agrees that in the event of any actual or threatened violation of this Section 8.1, Sellers and any of their Affiliates shall be entitled, in addition to other remedies that they may have, to a temporary restraining order and to preliminary and final injunctive relief against Buyer or such Affiliate of Buyer to prevent any violations of this Section 8.1, without the necessity of posting a bond.

(b) Sellers hereby grant to Buyer for 24 months following the Closing Date with respect to inventory and packaging material in stock as of the Closing Date and 60 days following the Closing Date with respect to signage and stationery and 180 days after the Closing Date with respect to promotional matters, each of which shall relate primarily to the Business, a non-exclusive, non-transferable, fully-paid and royalty-free license to use the "Viskase" name (the "Mark") in connection with the transition of the names used by the Business to new names. Notwithstanding the foregoing, Buyer and its Affiliates (including Newco Brazil after the Closing) shall use commercially reasonable efforts to change all references to the Mark as soon as practicable following the Closing Date, and shall make clear in all correspondence and communications made by Buyer that the Business is no longer owned by Sellers.

Section 8.2. Tax Matters. (a) Liability for Taxes. (i) Sellers shall be liable for and pay, and pursuant to Article XI (and subject to the limitations thereof) agree to indemnify and hold harmless each Buyer Group Member from and against any and all Taxes (A) imposed on Newco Brazil pursuant to Treas. Reg. § 1.1502-6 or similar provision of state, local or foreign law solely as a result of Newco Brazil having been a member of a Seller's Group, (B) imposed on Newco Brazil as a result of the Brazil Transactions, (C) imposed on Newco Brazil, or for which Newco Brazil may otherwise be liable, or (D) applicable to the Business and the Purchased Assets, in each case attributable to any taxable year or period that ends on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period ending on and including the Closing Date; provided, however, with respect to Taxes other than income or franchise Taxes of the Business, only to the extent that the amount of such other Taxes exceeds the amount of such other Taxes that have been provided for in the Valuation Date Statement, provided, further, that Sellers shall not be liable for or pay, and do not agree to indemnify and hold harmless each Buyer Group Member from and against, (I) any Taxes that result from any actual or deemed election under Section 338 of the Code or any similar provisions of state, local or foreign law as a result of the purchase of the Newco Brazil Shares or that result from Buyer, any Affiliate of Buyer, or Newco Brazil engaging in any activity or transaction that would cause the transactions contemplated by this Agreement to be treated as a purchase or sale of assets of Newco Brazil for federal, state, foreign or local Tax purposes and (II) any Taxes imposed on Newco Brazil, or for which Newco Brazil may otherwise be liable, as a result of transactions occurring on the Closing Date that are properly allocable (based on, among other relevant factors, factors set forth in Treas. Reg. § 1.1502-76(b)(1)(ii)(B)) to the portion of the Closing Date after the Closing (Taxes described in this proviso, hereinafter "Excluded Taxes"). Buyer and Sellers agree that, with respect to any transaction described in clause (II) of the preceding sentence, Newco Brazil and all persons related to Newco Brazil under Section 267(b) of the Code immediately after the Closing shall treat the transaction for all federal income Tax purposes (in accordance with Treas. Reg. § 1.1502-76(b)(1)(ii)(B)), and (to the extent permitted) for other income Tax purposes, as occurring at the beginning of the day following the Closing Date. Sellers shall be entitled to any refund of (or credit for) Taxes allocable to any taxable year or period that ends on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period ending on and including the Closing Date.

(ii) Buyer shall be liable for and pay, and pursuant to Article XI (and subject to the limitations thereof) agrees to indemnify and hold harmless each Seller Group Member from and against, (A) any and all Taxes imposed on Newco Brazil, or for which Newco Brazil may otherwise be liable and (B) all Taxes applicable to the Business or the Purchased Assets, in each case applicable to any taxable year or period that begins after the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period beginning after the Closing Date and (C) Excluded Taxes. Except as otherwise provided herein, Buyer shall be entitled to any refund of (or credit for) Taxes allocable to any taxable year or period that begins after the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period beginning after the Closing Date, to the extent the refund relates to any Taxes imposed on Buyer.

(iii) For purposes of paragraphs (a)(i) and (a)(ii), whenever it is necessary to determine the liability for Taxes of Newco Brazil or with respect to the Business and the Purchased Assets for a Straddle Period, the determination of the Taxes of Newco Brazil or with respect to the Business and the Purchased Assets for the portion of the Straddle Period ending on and including, and the portion of the Straddle Period beginning after, the Closing Date shall be determined by assuming that the Straddle Period consisted of two taxable years or periods, one which ended at the close of the Closing Date and the other which began at the beginning of the day following the Closing Date, and items of income, gain, deduction, loss or credit of Newco Brazil or with respect to the Business and the Purchased Assets for the Straddle Period shall be allocated between such two taxable years or periods on a "closing of the books basis" by assuming that the books of Newco Brazil or the Purchased Assets were closed at the close of the Closing Date, provided, however, that

(I) transactions occurring on the Closing Date that are properly allocable (based on, among other relevant factors, factors set forth in Treas. Reg. § 1.1502-76(b)(1)(ii)(B) with respect to federal law) to the portion of the Closing Date after the Closing shall be allocated to the taxable year or period that is deemed to begin at the beginning of the day following the Closing Date and (II) exemptions, allowances or deductions that are calculated on an annual basis, such as the deduction for depreciation, shall be apportioned between such two taxable years or periods on a daily basis. Notwithstanding the foregoing provisions of this paragraph (a)(iii), if the transactions contemplated by this Agreement result in the reassessment of the value of any property owned by Newco Brazil or of the Purchased Assets or assets of the Business for property Tax purposes, or the imposition of any property Taxes at a rate which is different than the rate that would have been imposed if such transactions had not occurred, then (y) the portion of such property Taxes for the portion of the Straddle Period ending on and including the Closing Date shall be determined on a daily basis, using the assessed value and Tax rate that would have applied had such transactions not occurred, and (z) the portion of such property Taxes for the portion of such Straddle Period beginning after the Closing Date shall be the total property Taxes for the Straddle Period minus the amount described in clause (y) of this sentence.

(iv) If, as a result of any action, suit, investigation, audit, claim, assessment or amended Tax Return, there is any change after the Closing Date in an item of income, gain, loss, deduction, credit or amount of Tax that results in an increase in a Tax liability for which Sellers would otherwise be liable pursuant to paragraph (a)(i) of this Section 8.2, and such change results in a decrease in the Tax liability of Newco Brazil, Buyer or any Affiliate or successor of any thereof for any taxable year or period beginning after the Closing Date or for the portion of any Straddle Period beginning after the Closing Date, Sellers shall not be liable pursuant to such paragraph (a)(i) with respect to such increase to the extent of such decrease (and, to the extent such increase in Tax liability is paid to a taxing authority by Sellers or any Affiliate thereof, Buyer shall pay Sellers an amount equal to such decrease).

(v) Except as provided in Section 4.5, notwithstanding anything herein to the contrary, Buyer shall pay, and agrees to indemnify and hold harmless each Seller Group Member from and against any and all real property transfer or gains Taxes, sales Taxes, use Taxes, stamp Taxes, stock transfer Taxes, asset transfer Taxes, or other similar Taxes imposed on the transactions contemplated by this Agreement on a purchaser under Requirements of Law; provided, however, that with respect to the sale of the Newco Brazil Shares, Buyer agrees to reimburse Sellers for one-half of any applicable withholding Taxes imposed on Sellers under Requirements of Law (it being understood that Buyer shall not pay more than $750,000 under this proviso). Buyer is agreeing to reimburse Sellers pursuant to the foregoing proviso, but is not hereby otherwise assuming any withholding Tax liability of Sellers.

(vi) Except as provided in Section 4.5, notwithstanding anything herein to the contrary, Sellers shall pay, and agree to indemnify and hold harmless each Buyer Group Member from and against any and all real property transfer or gains Taxes, sales Taxes, use Taxes, stamp Taxes, stock transfer Taxes, asset transfer Taxes, or similar Taxes imposed on the transactions contemplated by this Agreement on a seller under Requirements of Law; provided, however, that with respect to the sale of the Newco Brazil Shares, Buyer agrees to make the payment as set forth in clause (v) above.

(b) Tax Returns. (i) Sellers shall timely file or cause to be timely filed when due (taking into account all extensions properly obtained) all Tax Returns that are (x) required to be filed by or with respect to Newco Brazil for taxable years or periods ending on or before the Closing Date (in the case of income, franchise and similar Tax Returns required to be filed by or with respect to Newco Brazil as well as Tax Returns required to be filed by or with respect to Newco Brazil on a combined, consolidated or unitary basis with Sellers or any Affiliate thereof) or (y) due on or before the Closing Date (with respect to other Tax Returns), and in each case Sellers shall remit or cause to be remitted

any Taxes due in respect of such Tax Returns, and Buyer shall timely file or cause to be timely filed when due (taking into account all extensions properly obtained) all other Tax Returns that are required to be filed by or with respect to Newco Brazil and Buyer shall remit or cause to be remitted any Taxes due in respect of such Tax Returns. With respect to Tax Returns to be filed by Buyer pursuant to the preceding sentence that relate to taxable years or periods ending on or before the Closing Date or that relate to any Straddle Period (I) such Tax Returns shall be filed in a manner consistent with past practice and no position shall be taken, election made or method adopted that is inconsistent with positions taken, elections made or methods used in prior periods in filing such Tax Returns (including, without limitation, any such position, election or method which would have the effect of accelerating income to periods for which Sellers are liable or deferring deductions to periods for which Buyer is liable) and (II) such Tax Returns shall be submitted to Sellers not later than 30 days prior to the due date for filing such Tax Returns (or, if such due date is within 45 days following the Closing Date, as promptly as practicable following the Closing Date) for review and approval by Sellers, which approval may not be unreasonably withheld, but may in all cases be withheld if such Tax Returns were not prepared in accordance with clause (I) of this sentence. Sellers or Buyer shall pay the other party for the Taxes for which Sellers or Buyer, respectively, is liable pursuant to paragraph (a) of this Section 8.2 but which are payable with any Tax Return to be filed by the other party pursuant to this paragraph (b) upon the written request of the party entitled to payment, setting forth in detail the computation of the amount owed by Sellers or Buyer, as the case may be, but in no event earlier than 10 business days prior to the due date for paying such Taxes.

(ii) None of Buyer or any Affiliate of Buyer shall (or shall cause or permit Newco Brazil to) amend, refile or otherwise modify (or grant an extension of any statute of limitation with respect to) any Tax Return relating in whole or in part to Newco Brazil or the Business or the Purchased Assets with respect to any taxable year or period ending on or before the Closing Date (or with respect to any Straddle Period) without the prior written consent of Sellers, which consent may not be unreasonably withheld.

(iii) Buyer shall promptly cause Newco Brazil to prepare and provide to Sellers a package of Tax information materials, including, without limitation, schedules and work papers (the "Tax Package") required by Sellers to enable Sellers to prepare and file all Tax Returns required to be prepared and filed by it pursuant to paragraph (b)(i). The Tax Package shall be completed in accordance with past practice, including past practice as to providing such information and as to the method of computation of separate taxable income or other relevant measure of income of Newco Brazil. Buyer shall cause the Tax Package to be delivered to Sellers within 90 days after the Closing Date.

(c) Contest Provisions. (i) Buyer shall promptly notify Sellers in writing upon receipt by Buyer, any of its Affiliates, or Newco Brazil of notice of any pending or threatened federal, state, local or foreign Tax audits, examinations or assessments which might affect the Tax liabilities for which Sellers may be liable pursuant to this Section 8.2.

(ii) Sellers shall have the sole right to represent Newco Brazil's interests in any Tax audit or administrative or court proceeding relating to taxable periods ending on or before the Closing Date or otherwise relating to Taxes for which Sellers may be liable pursuant to this Section 8.2, and to employ counsel of their choice at their expense. Buyer shall be entitled to participate at its expense in any such audit or proceeding. In the case of a Straddle Period, Sellers shall be entitled to participate at their expense in any Tax audit or administrative or court proceeding relating (in whole or in part) to Taxes attributable to the portion of such Straddle Period ending on and including the Closing Date and, with the written consent of Buyer, and at Sellers' sole expense, may assume the entire control of such audit or proceeding. None of Buyer, any of its Affiliates, or Newco Brazil may settle any Tax claim for any Taxes for which Sellers may be liable pursuant to paragraph (a) of this Section 8.2, without the prior written consent of Sellers, which consent may not be unreasonably withheld.

(d) Assistance and Cooperation. After the Closing Date, each of Sellers and Buyer shall (and cause their respective Affiliates to):

(i) assist the other party in preparing any Tax Returns which such other party is responsible for preparing and filing in accordance with paragraph (b) of this Section 8.2;

(e) Election Under Section 338. Sellers and Buyer agree that Buyer may, in its discretion, make any election under Section 338 of the Code or under any applicable similar provision of state or foreign law with respect to Newco Brazil.

Section 8.3. Employee Matters—Employees of Asset Sellers, Other Than UK. (a) Effective as of the Closing Date, each Asset Seller shall terminate the employment of, and Buyer shall offer employment to all of the employees working at the plants located at Pauls Valley, Oklahoma and Centerville, Iowa. In addition, effective as of the Closing Date, each Asset Seller shall terminate the employment of, and Buyer shall offer employment to, virtually all "Chicago" employees listed on Schedule 8.3(a) (any employees and individuals who accept such offers of employment from Buyer and actually commence work with Buyer shall be referred to herein as the "Affected Employees"). Buyer may offer employment to certain of the individuals listed on Schedule 8.3(a) for a transition period; provided, however, that with respect to any individual that Buyer offers employment for a transition period, Buyer may not condition the offer of employment for a transition period on the individual's relocation to any other job location (such individuals who accept employment for a transition period shall be referred to herein as "Transition Employees" and, unless otherwise specified, the term "Affected Employee" shall include each Transition Employee).

(b) For a period commencing on the Closing Date and ending no earlier than the first anniversary of the Closing Date, Buyer shall take any action necessary so that each Affected Employee who continues to be employed in the Business or otherwise by Buyer shall continue to receive a level of employee benefits and base wages or salary, and bonus, that, in the aggregate, is substantially similar to such employee than the level of employee benefits and base wages or salary, and bonus, paid or provided by the Asset Sellers to such Affected Employee on the date of this Agreement;provided, however, that Buyer shall in no event be required to offer retiree medical benefits to any employee of Sellers (whether such benefits relate to pre-Closing or post-Closing service). In addition, Buyer agrees to provide, as of the Closing Date, insurance and other similar benefits as are available to employees of

Buyer in similar jobs. Sellers shall be responsible for satisfying all requirements under Part 6 of Title I of ERISA and Section 4980B of the Code ("COBRA") for continuation of coverage under all plans of group health coverage maintained by Sellers that is required to be provided before, on or after the Closing Date to (i) any "qualified beneficiary" whose "qualifying event" (as such terms are defined in COBRA) occurred prior to the Closing Date, including any such individual whose period for electing COBRA coverage has not expired as of the Closing Date, and (ii) any Affected Employee or dependent of an Affected Employee whose "qualifying event" with respect to Sellers' plans occurs on the Closing Date.

(c) Sellers shall give notice to all Affected Employees employed by the Asset Sellers that the active participation of such employees in the Pension Plans and Welfare Plans of Sellers shall terminate on the Closing Date, as of which date such employees shall be eligible to participate in Buyer's benefit programs. Except as otherwise expressly provided in this Section 8.3, in no event shall any Affected Employee be entitled to accrue any benefits under the Pension or Welfare Plans of Sellers with respect to services rendered or compensation paid after the Closing.

(d) Sellers shall take all actions necessary to cause each Affected Employee to be 100 percent vested in said employee's benefit under the SAVE Program for Employees of Viskase Corporation (the "SAVE Program") as of the Closing Date, and shall make all contributions under the SAVE Program (including any matching or other employer contributions) for all periods prior to the Closing Date as soon as administratively feasible after the Closing Date. As soon as practicable after the Closing Date (but in no event later than six months after the Closing Date), Buyer shall take all necessary actions so that each Affected Employee has the opportunity to elect a direct rollover pursuant to Section 401(a)(31) of the Code of the employee's benefit under the SAVE Program to any qualified defined contribution plan maintained or established by Buyer in which the Affected Employee is a participant on the date the direct rollover is to occur (or to the plan designated by Buyer to accept the direct rollover in the event the employee is a participant in more than one such plan). Any such direct rollover shall be made in cash, except that the direct rollover may include any outstanding loan to the employee from the employee's accounts in the SAVE Program. Prior to any direct rollover under this subsection, Buyer shall provide to Sellers the certification required under the applicable IRS regulations relating to rollover contributions regarding the qualified status of the plan or plans of Buyer which will receive the direct rollovers, and Sellers shall provide to Buyer the corresponding certification regarding the qualified status of the SAVE Program.

(e) Buyer shall recognize all unused vacation of the Affected Employees as of the Closing Date as shown on the Valuation Date Statement, and Buyer shall provide such paid vacation. Buyer shall recognize the bonus programs for Affected Employees existing as of the Closing Date and shall pay to the Affected Employees the bonuses they have accrued under such programs at the end of the bonus determination period as shown on the Valuation Date Statement, or earlier if so determined by Buyer.

(f) Affected Employees shall be credited for their length of service with the Companies for all purposes (other than for determining pension benefit accruals) under Buyer's benefit plans as if such service had been rendered to Buyer.

(g) Buyer shall (i) waive all limitations as to preexisting conditions, exclusions and waiting periods with respect to the Affected Employees under any welfare or fringe benefit plan (including, but not limited to, medical, dental and disability coverage) in which such employees may be eligible to participate after the Closing Date, and (ii) use its commercially reasonable efforts to credit Affected Employees with any amounts paid under Sellers' Welfare Plans prior to the Closing Date toward satisfaction of the applicable deductible amounts, copayment minimums, coinsurance amounts and out of pocket maximums under the corresponding Welfare Plans of Buyer to the extent such amounts would be taken into account under the Welfare Plans maintained by Buyer with respect to similarly situated employees.

(h) Sellers shall remain responsible for all claims under the applicable Welfare Plans of Sellers for health, accident and sickness benefits that are deemed incurred by Affected Employees prior to the Closing Date. Buyer shall be liable and responsible for all claims incurred for health, accident and sickness benefits that are deemed incurred by Affected Employees on or after the Closing Date. For all purposes under such Welfare Plans, Affected Employees will be deemed to have terminated employment with Sellers as of the Closing Date. For purposes of this Agreement: (i) a claim for health benefits (including, without limitation, claims for medical, prescription drug, dental, and vision care expenses) will be deemed to have been incurred on the date that health benefits services giving rise to such claim are provided, (ii) a claim for short-term or long-term disability benefits shall be deemed to have been incurred on the date the claim for such benefits is made (subject to the terms of Section 8.3(i)) and (iii) in the case of any claim for any other accident benefits, a claim will be deemed to have been incurred upon the occurrence of the event giving rise to such claims. Notwithstanding the foregoing provisions of this paragraph, Buyer shall have no liability for any such claim incurred by an Affected Employee or a dependent of an Affected Employee on or after the Closing Date if (i) such Affected Employee or dependent elected COBRA coverage under Sellers' Welfare Plans before, on or after the Closing Date and (ii) such claim is covered under that COBRA coverage.

(i) Sellers shall continue to be responsible for payment of all short-term disability claims for any Covered Employee who is on short-term disability at the Closing Date ("Disabled Employees"), unless and until such Covered Employee actually commences work for Buyer, at which time Buyer will be responsible for providing any future short-term disability coverage. Buyer will offer employment to persons on short-term disability at Pauls Valley, Oklahoma and Centerville, Iowa and to those persons listed in Schedule 8.3(a) when such persons are able to return to work. Such persons will become "Affected Employees" for purposes of this Agreement once they are employed by Buyer. Buyer will be responsible for providing long-term disability coverage to any Covered Employee who commences work for Buyer after Closing (to the same extent such coverage is available to Buyer's other employees), except for Disabled Employees who move directly to long-term disability coverage without reporting to work with Buyer, and Sellers will be responsible for providing such long-term disability coverage to such Disabled Employees.

(j) Attached hereto as Schedule 8.3(j) are copies of Sellers' Severance Pay Policy, Severance Allowance Plan (Salaried) and Severance Layoff Allowance Plan (Hourly) (the "Policies"). With respect to any person listed on Schedule 8.3(a) who is not offered employment by Buyer (or who is offered employment with Buyer at a lower salary than that in effect as of the Closing Date), Buyer agrees to reimburse Sellers for any amounts paid by Sellers under the Policies to any such person, as well as for any other costs incurred by Sellers in satisfying all obligations under the Policies. Except as otherwise provided herein, Sellers shall be liable for all severance pay obligations (under the Policies or otherwise) to any persons listed on Schedule 8.3(a) who are offered employment by Buyer (under terms described in the first two sentences of Section 8.3(b)), but who do not accept such offer or do not actually commence work for Buyer. Any person offered permanent employment by Buyer may accept a temporary position with Buyer in which case any severance owed to such employee shall not be payable until such temporary position with Buyer has ended (which severance shall be payable by Sellers); provided, however, that if any such person then accepts a permanent position with Buyer, Buyer will then become responsible for severance obligations to such persons under the Policies. After the Closing Date and for a period of twenty-four months thereafter, Buyer will be responsible for, and pay, any severance liability of Sellers to any Affected Employee whose employment with Buyer is terminated, provided such persons are entitled to severance under the Severance Pay Policy as a result of the occurrence of a "Change of Control" (as defined in such Policy).

(k) Except as provided in the preceding paragraphs of this Section or in the following sentence, Buyer shall be solely responsible for (i) all liabilities, obligations and commitments relating to all wages, salaries, bonuses and other forms of compensation (including vacation pay) and related expenses

incurred or accrued on or after the Closing Date with respect to Affected Employees, (ii) all employee benefits accrued after the Closing Date under any and all plans, programs or arrangements maintained or contributed to by Buyer for the benefit of Affected Employees and (iii) all medical, dental and other health benefits or claims incurred after the Closing Date (other than benefits or claims payable under Sellers' Welfare Plans due to a COBRA election made by an Affected Employee or a dependent of an Affected Employee). Sellers shall remain liable for providing retiree welfare benefits to all Affected Employees who, as of the Closing Date, satisfy the eligibility requirements for retiree welfare benefits under the applicable terms and conditions of Sellers' Welfare Plans as in effect on the Closing Date and shall provide such benefits in accordance with the terms of such plans. In no event shall Sellers be obligated to provide retiree welfare benefits to Affected Employees who do not, as of the Closing Date, satisfy the applicable eligibility requirements for retiree welfare benefits under Sellers' Welfare Plans as in effect on the Closing Date.

(l) Sellers shall be responsible for all liabilities or obligations under the Worker Adjustment and Retraining Notification Act and similar state, foreign and local rules, statutes and ordinances resulting from Sellers' actions prior to the Closing. Buyer shall be responsible for all liabilities or obligations under the Worker Adjustment and Retraining Notification Act and similar state, foreign and local rules, statutes and ordinances resulting from the Closing or from Buyer's actions following the Closing.

(m) Except as otherwise provided in this Section or as required by law, nothing in this Agreement shall be interpreted as limiting the power of Buyer to amend or terminate any particular plan maintained by Buyer or as requiring Buyer to continue the employment of any specific person for any particular time; provided, however, that no such termination or amendment may take away benefits or any other payments already accrued as of the time of termination or amendment without the consent of such person, except as allowed by law.

(n) After the date hereof, Sellers shall not amend any of the Policies to provide greater benefits to any persons for whom Buyer is or may be obligated to provide severance under this Section 8.3.

(o) Buyer shall be responsible for, and shall indemnify and hold harmless Sellers from and against, any and all Losses and Expenses relating to or arising out of the liabilities assumed by Buyer under this Section 8.3 or any failure by Buyer to comply with the provisions of this Section 8.3.

Section 8.4. Employee Matters—Employees of Brazil and Employees Employed at Swansea. (a) Buyer shall take any action necessary so that each person who immediately prior to the Closing Date is an employee of Newco Brazil consisting solely of former employees of Viskase Brazil listed on Schedule 8.4(a) who immediately prior to the Closing Date are primarily engaged in the Business (including each such employee who is on vacation, temporary layoff, approved leave of absence, military leave, sick leave or short-term disability) shall remain an employee of Newco Brazil, as the case may be, immediately following the Closing Date. In addition, effective as of the Closing Date, each Asset Seller shall terminate the employment of, and Buyer shall offer employment to employees of UK listed on Schedule 5.18(g)(i).

(b) Buyer shall also take any necessary action so that each employee benefit plan maintained by, or required to be contributed to by, Brazil or UK for Foreign Affected Employees shall be continued immediately following the Closing Date and all service recognized under each such plan shall continue to be recognized after the Closing Date. Notwithstanding anything contained herein to the contrary, on and after the Closing Date, Buyer shall continue to be bound to the extent required by law by the provisions of each prior offer of employment by Sellers to Foreign Affected Employees and by the employment agreements, collective bargaining agreements, collective employee agreements, customary practices and other employment-related obligations applicable and relevant to Foreign Affected Employees, to the extent required by local law or the provisions of those agreements. Nothing herein

shall prevent Buyer from modifying the Foreign Affected Employees' terms and conditions of employment or establishing new terms and conditions of employment to the extent such actions are permitted by local law and the provisions of such agreements; provided, however, that Buyer shall be responsible for all claims, obligations and liabilities of any kind arising out of changes made by Buyer after the Closing Date to employment agreements, collective bargaining agreements, collective employee agreements, customary practices and other employment-related obligations applicable and related to Foreign Affected Employees.

(c) To the extent that Buyer is not obligated by any prior offer of employment, any agreement, any customary practice or otherwise by law to provide a specific level of compensation or employee benefits to any Foreign Affected Employee, Buyer shall, for a period commencing on the Closing Date and ending no earlier than the first anniversary of the Closing Date, take any action necessary so that each such Foreign Affected Employee who continues to be employed in the Business or otherwise by Buyer shall continue to receive a level of employee benefits and base wages or salary that, in the aggregate, is no less favorable to such employee than the level of employee benefits and base wages or salary paid or provided by the Companies to such Foreign Affected Employee on the date of this Agreement.

(d) Buyer shall be solely liable and responsible for all obligations and commitments incurred after the Closing Date relating to Affected Employees and Foreign Affected Employees who become employed by Buyer.

(i) Buyer may, upon becoming aware of any such contract, terminate it forthwith; and

(ii) Sellers shall indemnify and keep indemnified Buyer against any costs, claims, liabilities and expenses of any nature arising out of such termination and against sums payable to or on behalf of such employee in respect of his employment whether arising before or after the Closing Date.

To the extent that after the Closing any party hereto requires any information regarding claim data, payroll or other information in order to make filing with insurance carriers or self insurance regulators from another party hereto, the other party or parties will promptly supply such information.

Section 8.7. Collection; Post-Closing Remittances. (a) For a period of 180 days after the Closing Date (the "Collection Period"), at no cost to Sellers, Buyer shall use its commercially reasonable efforts to collect the accounts and notes receivable of UK, Ireland, Viskase Brazil and Chile (the "Receivables") generally in accordance with the billing and collection practices presently applied by such Companies in the collection of their accounts and notes receivable, except that with respect to any particular Receivable, Buyer shall be under no obligation to commence or not to commence litigation to effect collection. Buyer shall use at least the same standard of care for the collection of the Receivables that it uses in its own business. In connection with the collections by Buyer, if a payment is received from an account debtor who has not designated the invoice being paid thereby, Buyer shall contact such account debtor to determine the invoice being paid thereby and, if no invoice is designated, then such payment shall be applied to a Receivable relating to a sale prior to the Closing Date. Buyer agrees not to knowingly take actions that are reasonably likely to diminish the collectibility of the Receivables.

(b) Buyer shall remit all cash collections from the Receivables to a bank account designated by Sellers on a weekly basis on each Tuesday during the Collection Period.

(c) Buyer shall, on a weekly basis on each Tuesday during the Collection Period, deliver to Sellers a written report ("Collection Report") of the following information with respect to the Receivables:

(i) The aggregate amount of the Receivables (and the number of accounts comprising such Receivables);

(ii) The amount of cash collections of the Receivables during the period relating to such Collection Report; and

(iii) Any material problems relating to the collection of Receivables.

(d) During the period that Buyer is collecting Receivables on behalf of Sellers, Buyer shall have the right and authority to endorse, without recourse, the name of Sellers on any check or other evidences of indebtedness received by Buyer on account of any Receivable and shall promptly remit the amount of such Receivable to Sellers in accordance with this Section 8.7. Without limiting the foregoing provisions of this Section 8.7, if, at any other time after the Closing Date, Buyer or its Affiliates shall receive any remittance from any account debtors with respect to any accounts or notes receivables included in the Excluded Assets, then Buyer or its Affiliates, as applicable, shall endorse such remittance to the order of the appropriate Seller and forward it to such Seller promptly following receipt thereof.

Section 8.8. Post-Closing Assistance. Following the Closing:

(a) Buyer shall provide to Sellers and their representatives and agents reasonable assistance in connection with the ANC Litigation and Newsome Litigation (as those terms are defined in the

Licensed Patents License Agreement) and any Excluded Liabilities, including those matters described in Schedule 2.4, upon reasonable notice (subject to reimbursement of costs and expenses), including providing reasonable access to facilities for inspections or obtaining information, reasonable access to documents for production or use in the litigation, and/or reasonable access to employees and officers, as necessary, for testimony at depositions and/or trial, and reasonable assistance with the conduct of the litigation. Following assignment of the Licensed Patents to Buyer, Seller agrees to provide the same assistance to Buyer in connection with the Newsome Litigation. The obligation to provide assistance pursuant to this Section 8.8 shall continue notwithstanding any termination of the Licensed Patents License Agreement.

(b) For a period of two (2) years following the Closing Date, Buyer shall make available to Sellers former employees of Sellers identified on Schedule 8.8 for consultation in connection with Sellers' NUCEL® technology. Such consultation shall be at times mutually agreed to by the parties and shall not unreasonably interfere with the principal duties of such employees.

(c) Sellers shall provide to Buyer and its representatives and agents reasonable access to Seller's facilities, records and documents and employees and officers, as reasonably requested by Buyer from time to time in connection with any Assumed Liabilities, including those matters described in Schedule 2.3(d).

(d) Each party hereto agrees to hold, and to cause its Affiliates, employees, agents and representatives to hold, in strict confidence all information (whether written or oral) obtained pursuant to this Section 8.8 and such information shall not be disclosed or released without the prior written consent of the party hereto that has provided access to such confidential information.

(e) Sellers or Buyer, as the case may be, will provide reasonable advance notice to such other party of any request for assistance pursuant to this Section 8.8. In addition, Sellers or Buyer, as the case may be, will reimburse such other party for any reasonable direct out-of-pocket expenses (including 130% of any per diem salary) incurred by such other party pursuant to this Section 8.8.

Section 8.9. Non-Competition. (a) Sellers and their Affiliates agree that they will not (directly or indirectly) enter into, engage in, invest in or consult with any entity in the business of manufacturing, selling or distributing specialty plastic films ("Competing Films Products") for a five year period after the Closing Date anywhere in the world. For a 30 month period after the Closing Date, Sellers shall not recruit or otherwise solicit or induce any Affected Employee or Foreign Affected Employee to terminate his or her employment or other relationship with Buyer or its Affiliates. Notwithstanding anything contained herein to the contrary, nothing in this Agreement shall prevent Sellers or any of their Affiliates from owning, directly or indirectly, up to 2% of any class of securities of any entity traded on any securities exchange regardless of whether or not such entity manufactures, distributes or sells Competing Films Products or products which compete with the Competing Films Products. In addition, notwithstanding anything contained herein to the contrary, this Section 8.9(a) shall not prevent (i) the continued operation by Sellers and their Affiliates of those products included in the Excluded Business or (ii) the acquisition of any Seller or Affiliates of any Seller by any entity engaged in the manufacture, sale and distribution of Competing Films Products, and the subsequent manufacture, sale or distribution of Competing Films Products by such acquiring company and its Affiliates (other than Sellers).

(b) Buyer and its Affiliates agree that they will not (directly or indirectly) enter into, engage in, invest in or consult with any entity in the business of manufacturing, selling or distributing nylon casings ("Competing Casings Products") for a five year period after the Closing Date anywhere in the world. For a 30 month period after the Closing Date, Buyer shall not recruit or otherwise solicit or induce any person who is an employee of the Sellers or their Affiliates to terminate his or her employment or other relationship with the Sellers or their Affiliates. Notwithstanding anything contained herein to the contrary, nothing in this Agreement shall prevent Buyer or any of its Affiliates

from owning, directly or indirectly, up to 2% of any class of securities of any entity traded on any securities exchange regardless of whether or not such entity manufactures, distributes or sells Competing Casings Products or products which compete with the Competing Casings Products. In addition, notwithstanding anything contained herein to the contrary, this Section 8.9(b) shall not prevent the acquisition of Buyer or its Affiliates by any entity engaged in the manufacture, sale and distribution of Competing Casings Products, and the subsequent manufacture, sale or distribution of Competing Casings Products by such acquiring company and its Affiliates (other than Buyer or its Affiliates).

Section 8.10. Casings License. From and after the Closing Date, Buyer hereby grants, without representation or warranty, to Sellers and their Affiliates a fully paid-up, royalty-free, non-exclusive, perpetual right and license to make, have made, use or sell any products the use, manufacture or sale of which is covered by the patents set forth in Schedule 8.10 (the "Casing Patents"). Sellers and any successor in interest of any Seller may sell, assign or sublicense the Sellers' license under the Casing Patents granted hereby, on the terms of and subject to the license granted hereunder, only to any subsequent owner, lessee or operator of the Excluded Business, provided that (i) such subsequent owner, lessee or operator agrees in writing to be bound by the terms of this Section 8.10 and (ii) written notice of the identity and address for notices of such subsequent owner, lessee or operator is delivered to Buyer prior to such sale, assignment or sublicense.

Section 8.11. Covenant Not to Sue. With respect to the patents listed on Schedule 8.11, Sellers agree not to assert against Buyer or its Affiliates any claims for infringement based upon Buyer's use, manufacture or sale of the products of the Business using the same formulation used by Sellers on or before the Closing Date as shown by the Product Standards and Procedures Specifications for such products in existence on or before the Closing Date. Sellers will agree to notify any subsequent purchaser or licensee of the patents listed on Schedule 8.11 of the existence and terms of this covenant and any such purchaser or licensee shall take whatever rights are granted to it by Sellers subject to the terms of this Section 8.11.

(i) any breach of any warranty or the inaccuracy of any representation of Sellers contained or referred to in this Agreement or the certificate delivered by or on behalf of Sellers pursuant to Section 9.1;

(ii) any breach by Sellers of, or failure by Sellers to perform, any of its covenants or obligations contained in this Agreement (excluding matters described in clauses (iii) and (iv) below);

(x) the aggregate amount of such Losses and Expenses exceeds $2,500,000 ($250,000 in regard to the representations and warranties contained in section 5.17) (it being understood that such one percent of the Final Purchase Price (and $250,000) shall be deductibles for which Sellers shall bear no indemnification responsibility); and

(y) the aggregate amount required to be paid by Sellers pursuant to Section 11.1(a)(i) shall not exceed $50,000,000; and

provided, further, that Sellers shall be required to indemnify and hold harmless under Section 11.1(a)(iv) with respect to Losses and Expenses incurred by Buyer Group Members only to the extent that the amount of Loss and Expense suffered by Buyer Group Members related to each

individual claim exceeds $10,000 (it being understood that such $10,000 shall be a deductible for which Sellers shall bear no indemnification responsibility); provided, further, that such $10,000 deductible shall cease to apply when all indemnified Losses and Expenses suffered by Buyer Group Members as to all such claims under this proviso exceed $100,000.

(b) The indemnification provided for in Section 11.1(a) shall terminate one year after the Closing Date (two years in regard to the representations and warranties contained in Section 5.17) (and no claims shall be made by any Buyer Group Member under Section 11.1(a) thereafter), except that the indemnification by Sellers shall continue as to:

(i) the obligations of Sellers with respect to Section 11.1(a)(iv), which shall survive until the expiration of the applicable statute of limitations for the underlying claim;

(ii) the covenants of Sellers set forth in Section 13.6, which shall survive for the period of time set forth therein;

(iii) the covenants of Sellers set forth in Article VIII and the obligations of Sellers with respect to Section 11.1(a)(iii), which shall survive indefinitely; and

(iv) any Losses or Expenses of which any Buyer Group Member has validly given a Claim Notice to Sellers in accordance with the requirements of Section 11.3 on or prior to the date such indemnification would otherwise terminate in accordance with this Section 11.1, as to which the obligation of Sellers shall continue solely with respect to the specific matters in such Claim Notice until the liability of Sellers shall have been determined pursuant to this Article XI, and Sellers shall have reimbursed all Buyer Group Members for the full amount of such Losses and Expenses that are payable with respect to such Claim Notice in accordance with this Article XI.

Section 11.2. Indemnification by Buyer. (a) Buyer agrees to indemnify and hold harmless each Seller Group Member from and against any and all Losses and Expenses incurred by such Seller Group Member in connection with or arising from:

(i) any breach of any warranty or the inaccuracy of any representation of Buyer contained or referred to in this Agreement or the certificate delivered by or on behalf of Buyer pursuant to Section 10.1;

(ii) the covenants of Buyer set forth in Section 13.6 which shall survive for the period of time set forth therein;

(iv) any Losses or Expenses of which any Seller Group Member has validly given a Claim Notice to Buyer in accordance with the requirements of Section 11.3 on or prior to the date such indemnification would otherwise terminate in accordance with this Section 11.2, as to which the

obligation of Buyer shall continue solely with respect to the specific matters in such Claim Notice until the liability of Buyer shall have been determined pursuant to this Article XI, and Buyer shall have reimbursed all Seller Group Members for the full amount of such Losses and Expenses that are payable with respect to such Claim Notice in accordance with this Article XI.

Section 11.3. Notice of Claims. Any Buyer Group Member or Seller Group Member seeking indemnification hereunder (the "Indemnified Party") shall give promptly to the party obligated to provide indemnification to such Indemnified Party (the "Indemnitor") a notice (a "Claim Notice") describing in reasonable detail the facts giving rise to the claim for indemnification hereunder and shall include in such Claim Notice (if then known) the amount or the method of computation of the amount of such claim, and a reference to the provision of this Agreement or any other agreement, document or instrument executed hereunder or in connection herewith upon which such claim is based; provided, however, that a Claim Notice in respect of any action at law or suit in equity by or against a third Person as to which indemnification will be sought shall be given promptly after the action or suit is commenced; provided, however, that failure to give notice as provided in this Section 11.3 shall not relieve the Indemnitor of its obligations hereunder except to the extent it shall have been prejudiced by such failure.

Section 11.4. Determination of Amount. (a) In calculating any Loss or Expense there shall be deducted any insurance recovery (excluding recoveries to the extent they are self-insured) in respect thereof (and no right of subrogation shall accrue hereunder to any insurer). Buyer and Sellers agree that, for purposes of computing the amount of any indemnification payment under this Article XI, any such indemnification payment shall be treated as an adjustment to the Final Purchase Price for all Tax purposes. Any such indemnification payment hereunder with respect to any Loss or Expense shall be an amount which is sufficient to compensate the Indemnified Party for the amount of such Loss or Expense, after taking into account (i) any Tax benefit which has been, or will be, provided to such Indemnified Party as a result of such Loss or Expense (such Indemnified Party shall use commercially reasonable efforts to obtain such Tax benefit, including filing amended Tax Returns if necessary) and (ii) all increases in federal, state, local, foreign or other Taxes payable by the Indemnified Party as a result of the receipt of such payment (by reason of such payment being included in income, resulting in a reduction of tax basis, or otherwise increasing such Taxes payable by the Indemnified Party at any time).

(b) After the giving of any Claim Notice pursuant to Section 11.3, the amount of indemnification to which an Indemnified Party shall be entitled under this Article XI shall be determined: (i) by the written agreement between the Indemnified Party and the Indemnitor; (ii) by a final judgment or decree of any court of competent jurisdiction; or (iii) by any other means to which the Indemnified Party and the Indemnitor shall agree. The judgment or decree of a court shall be deemed final when the time for appeal, if any, shall have expired and no appeal shall have been taken or when all appeals taken shall have been finally determined. The Indemnified Party shall have the burden of proof in establishing the amount of Losses and Expenses suffered by it.

Section 11.5. Third Person Claims. (a) Any party seeking indemnification provided for under this Agreement in respect of, arising out of or involving a claim or demand made by any third Person against the Indemnified Party shall notify the Indemnitor in writing, and in reasonable detail, of the third Person claim within 10 days after receipt by such Indemnified Party of written notice of the third Person claim. Thereafter, the Indemnified Party shall deliver to the Indemnitor, within five business days after the Indemnified Party's receipt thereof, copies of all notices and documents (including court papers) received by the Indemnitor relating to the third Person claim. Notwithstanding the foregoing, should a party be physically served with a complaint with regard to a third Person claim, the Indemnified Party shall notify the Indemnitor with a copy of the complaint within five business days after receipt thereof and shall deliver to the Indemnitor within seven business days after the receipt of such complaint copies of notices and documents (including court papers) received by the Indemnified

Party relating to the third Person claim. The failure to give notice as provided in this Section 11.5 shall not relieve the Indemnitor of its obligations hereunder except to the extent it shall have been prejudiced by such failure.

(b) In the event any legal proceeding shall be threatened in writing or instituted or any claim or demand shall be asserted in writing by any Person in respect of which payment may be sought by one party hereto from the other party under the provisions of this Article XI, the Indemnified Party shall promptly cause written notice of the assertion of any such claim of which it has knowledge which is covered by this indemnity to be forwarded to the Indemnitor. Any notice of a claim by reason of any of the representations, warranties or covenants contained in this Agreement shall contain a reference to the provision of this Agreement or any other agreement, document or instrument executed hereunder or in connection herewith upon which such claim is based, the facts giving rise to an alleged basis for the claim and the amount of the liability asserted against the Indemnitor by reason of the claim. In the event of the initiation of any legal proceeding against the Indemnified Party by a third Person, the Indemnitor shall have the sole and absolute right after the receipt of notice, at its option and at its own expense, to be represented by counsel of its choice (reasonably acceptable to the Indemnified Party) and to control, defend against, negotiate, settle or otherwise deal with any proceeding, claim, or demand which relates to any loss, liability or damage indemnified against hereunder; provided, however, that the Indemnified Party may participate in any such proceeding with counsel of its choice and at its expense. The parties hereto agree to cooperate fully with each other in connection with the defense, negotiation or settlement of any such legal proceeding, claim or demand. To the extent the Indemnitor elects not to defend such proceeding, claim or demand, and the Indemnified Party defends against or otherwise deals with any such proceeding, claim or demand, the Indemnified Party may retain counsel, at the expense of the Indemnitor, and control the defense of such proceeding. Neither the Indemnitor nor the Indemnified Party may settle any such proceeding which settlement obligates the other party to pay money, to perform obligations or to admit liability without the consent of the other party. After any final judgment or award shall have been rendered by a court, arbitration board or administrative agency of competent jurisdiction and the time in which to appeal therefrom has expired, or a settlement shall have been consummated, or the Indemnified Party and the Indemnitor shall arrive at a mutually binding agreement with respect to each separate matter alleged to be indemnified by the Indemnitor hereunder, the Indemnified Party shall forward to the Indemnitor notice of any sums due and owing by it with respect to such matter and the Indemnitor shall pay all of the sums so owing to the Indemnified Party by wire transfer, certified or bank cashier's check within 30 days after the date of such notice.

(c) Notwithstanding anything contained herein to the contrary, Sellers shall have the exclusive right to assume the defense of, or otherwise contest or settle any claim, action, suit, investigation or proceeding which is an Excluded Liability. Buyer agrees to cooperate and assist Sellers with all reasonable requests (including, without limitation, making employees available for interviews, depositions and trials) and to afford Sellers access to any records, reports or other documents reasonably requested by Sellers in connection with such claims, actions, suits or proceedings.

(d) To the extent of any inconsistency between this Section 11.5 and Section 8.2(c) (relating to Tax contests), the provisions of Section 8.2(c) shall control with respect to Tax contests.

Section 11.6. Limitations. (a) In any case where an Indemnified Party recovers from third Persons any amount in respect of a matter with respect to which an Indemnitor has indemnified it pursuant to this Article XI, such Indemnified Party shall promptly pay over to the Indemnitor the amount so recovered (after deducting therefrom the full amount of the expenses incurred by it in procuring such recovery), but not in excess of the sum of (i) any amount previously so paid by the Indemnitor to or on behalf of the Indemnified Party in respect of such matter and (ii) any amount expended by the Indemnitor in pursuing or defending any claim arising out of such matter.

(b) Sellers shall not be required to indemnify and hold harmless any Buyer Group Member pursuant to Section 11.1(a) to the extent the matter in question was taken into account in the computation of the Final Purchase Price pursuant to Section 3.2.

(c) In the event that Sellers are conducting any defense against a third Person claim for which a Buyer Group Member has sought indemnification pursuant to Section 11.1(a), expenses incurred by Sellers in connection therewith, including legal costs and expenses, shall constitute Expenses for purposes of determining the maximum aggregate amount to be paid by Sellers pursuant to Section 11.1(a).

(d) No party shall have any liability for any inaccuracy in or breach of any representation, warranty or agreement by such party if the other party or any of its officers, employees, counsel or other representatives had actual knowledge on or before the Closing Date of the facts as a result of which such representation, warranty or agreement was inaccurate or breached.

(e) Except for remedies that cannot be waived as a matter of law and injunctive and provisional relief (including, but not limited to, specific performance), if the Closing occurs, this Article XI shall be the exclusive remedy for breaches of this Agreement (including any covenant, obligation, representation or warranty contained in this Agreement or in any certificate delivered pursuant to this Agreement) or otherwise in respect of the sale of the Purchased Assets contemplated hereby. The parties agree that their respective rights and obligations in respect of Environmental Matters as provided in this Agreement shall supersede any such rights and obligations they may have under any existing or future law. Except for any Losses or Expenses for which Sellers are required to indemnify and hold harmless the Buyer Group members in accordance with Section 11.1(a)(i), Buyer releases Sellers from any and all liability for Losses and Expenses relating to Environmental Matters arising in connection with the Business or the Purchased Assets.

(f) Notwithstanding any other provision of this Agreement, Sellers shall have no indemnification obligations with respect to any breach of any representation or warranty contained in Section 5.17 to the extent that such breach was discovered or otherwise identified through any voluntary investigation undertaken by Buyer or its Affiliates, including any soil or groundwater sampling. Sellers and Buyer agree that any demand or request by any governmental agency or court (or by any third party asserting a claim against Buyer or alleging liability on the part of Buyer) for any investigation or remediation of any property, including any soil or groundwater sampling, shall be deemed to be an involuntary investigation and therefore not governed by the provisions of the preceding sentence unless initiated by a voluntary request or disclosure by Buyer.

Section 11.7. Mitigation. Each of the parties agrees to take all reasonable steps to mitigate their respective Losses and Expenses upon and after becoming aware of any event or condition which could reasonably be expected to give rise to any Losses and Expenses that are indemnifiable hereunder; provided, however, that no party shall be obligated to expend money, commence or participate in any litigation or offer or grant any accommodation (financial or otherwise) to any third party.

ARTICLE XII

(d) by Buyer or Sellers if any court of competent jurisdiction in the United States or other United States Governmental Body shall have issued a final and non-appealable order, decree or ruling permanently restraining, enjoining or otherwise prohibiting the consummation of the transactions contemplated hereby; or

(e) by Buyer or Sellers if the Closing shall not have occurred on or before September 30, 2000 (or such later date as may be agreed in writing to by Buyer and Sellers), unless the failure of such consummation shall be due to the failure of the party seeking to terminate this Agreement to comply in all material respects with the agreements and covenants contained herein to be performed by such party on or before the Closing Date.

Section 12.2. Notice of Termination. Any party desiring to terminate this Agreement pursuant to Section 12.1 shall give written notice of such termination to the other party to this Agreement.

Section 12.4. Non-Solicitation.

Without limiting the rights of Sellers to pursue all other legal and equitable rights available for a violation of this Section 12.4 by Buyer or its Affiliates, it is agreed that other remedies cannot fully compensate Sellers for such a violation and that Sellers shall be entitled to injunctive relief to prevent a violation or continuing violation hereof.

Section 13.5. Successors and Assigns. (a) The rights of any party under this Agreement shall not be assignable by such party hereto prior to the Closing without the written consent of the other parties except that the rights of Buyer hereunder may be assigned in whole or in part prior to the Closing, without the consent of Sellers, to one or more corporations or limited liability companies all of the outstanding capital stock or equity interests of which is owned or controlled by Buyer; provided that (i) such assignment shall not result in Buyer or Sellers having to amend their respective Notification and Report Form filed under the HSR Act in connection with the transactions contemplated hereunder, (ii) the assignee shall assume in writing all of Buyer's obligations to Sellers hereunder in

proportion to the extent of such assignment by Buyer of its rights hereunder and (iii) Buyer shall not be released from any of its obligations hereunder by reason of such assignment.

(b) Following the Closing, no party may assign any of its rights hereunder to any third Person without the written consent of the other parties, except that a party may assign its rights hereunder to an Affiliate. Any assignment hereunder (whether before or after the Closing) shall not relieve the assigning party of its obligations hereunder. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their successors and permitted assigns. Nothing in this Agreement, expressed or implied, is intended or shall be construed to confer upon any Person other than the parties and successors and assigns permitted by this Section 13.5 any right, remedy or claim under or by reason of this Agreement.

Section 13.6. Access to Records after Closing. (a) For a period of six years after the Closing Date, Sellers and their representatives shall have reasonable access to all of the books and records of the Business to the extent that such access may reasonably be required by Sellers in connection with matters relating to or affected by the operations of the Business prior to the Closing Date. Such access shall be afforded by Buyer upon receipt of reasonable advance notice and during normal business hours. Sellers shall be solely responsible for any costs or expenses incurred by it pursuant to this Section 13.6(a). If Buyer or its Affiliates (including Newco Brazil after the Closing) shall desire to dispose of any of such books and records prior to the expiration of such six-year period, Buyer shall, prior to such disposition, give Sellers a reasonable opportunity, at Sellers' expense, to segregate and remove such books and records as Sellers may select.

(b) For a period of six years after the Closing Date, Buyer and its representatives shall have reasonable access to all of the books and records relating to the Business which Sellers or any of their Affiliates may retain after the Closing Date. Such access shall be afforded by Sellers and their Affiliates upon receipt of reasonable advance notice and during normal business hours. Buyer shall be solely responsible for any costs and expenses incurred by it pursuant to this Section 13.6(b). If Sellers or any of its Affiliates shall desire to dispose of any of such books and records prior to the expiration of such six-year period, Sellers shall, prior to such disposition, give Buyer a reasonable opportunity, at Buyer's expense, to segregate and remove such books and records as Buyer may select.

Section 13.7. Entire Agreement; Amendments. This Agreement, the Exhibits and Schedules referred to herein, the documents delivered pursuant hereto and the Confidentiality Agreement contain the entire understanding of the parties hereto with regard to the subject matter contained herein or therein, and supersede all other prior representations, warranties, agreements, understandings or letters of intent between or among any of the parties hereto. This Agreement shall not be amended, modified or supplemented except by a written instrument signed by an authorized representative of each of the parties hereto.

Section 13.8. Interpretation. Articles, titles and headings to sections herein are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement. The Schedules and Exhibits referred to herein shall be construed with and as an integral part of this Agreement to the same extent as if they were set forth verbatim herein. The Schedules referred to herein are attached to that certain letter of even date herewith from Sellers to Buyer (the "Disclosure Letter"). Disclosure of any fact or item in any Schedule hereto referenced by a particular section in this Agreement shall be deemed to have been disclosed with respect to every other section in this Agreement if a reasonable person would reasonably ascertain that such disclosure should reasonably apply to other sections in this Agreement. Neither the specification of any dollar amount in any representation or warranty contained in this Agreement nor the inclusion of any specific item in any Schedule hereto is intended to imply that such amount, or higher or lower amounts, or the item so included or other items, are or are not material, and no party shall use the fact of the setting forth of any such amount or the inclusion of any such item in any dispute or controversy between the

parties as to whether any obligation, item or matter not described herein or included in any Schedule is or is not material for purposes of this Agreement. Unless this Agreement specifically provides otherwise, neither the specification of any item or matter in any representation or warranty contained in this Agreement nor the inclusion of any specific item in any Schedule hereto is intended to imply that such item or matter, or other items or matters, are or are not in the ordinary course of business, and no party shall use the fact of the setting forth or the inclusion of any such item or matter in any dispute or controversy between the parties as to whether any obligation, item or matter not described herein or included in any Schedule is or is not in the ordinary course of business for purposes of this Agreement. Sellers may, from time to time prior to or at the Closing, by notice in accordance with the terms of this Agreement, supplement, amend or create any Schedule, in order to add information or correct previously supplied information. No such amendment shall be evidence, in and of itself, that the representations and warranties in the corresponding section are no longer true and correct in all material respects. It is specifically agreed that such Schedules may be amended to add immaterial, as well as material, items thereto. No such supplemental, amended or additional Schedule shall be deemed to cure any breach for purposes of Section 9.1, unless Buyer does not object to such supplemental, amended or additional Schedule within five business days after receipt thereof. If, however, the Closing occurs, any such supplement, amendment or addition will be effective to cure and correct for all other purposes any breach of any representation, warranty or covenant which would have existed if Sellers had not made such supplement, amendment or addition, and all references to any Schedule hereto which is supplemented or amended as provided in this Section 13.8 shall for all purposes after the Closing be deemed to be a reference to such Schedule as so supplemented or amended.

Section 13.9. Waivers. Any term or provision of this Agreement may be waived, or the time for its performance may be extended, by the party or parties entitled to the benefit thereof. Any such waiver shall be validly and sufficiently authorized for the purposes of this Agreement if, as to any party, it is authorized in writing by an authorized representative of such party. The failure of any party hereto to enforce at any time any provision of this Agreement shall not be construed to be a waiver of such provision, nor in any way to affect the validity of this Agreement or any part hereof or the right of any party thereafter to enforce each and every such provision. No waiver of any breach of this Agreement shall be held to constitute a waiver of any other or subsequent breach.

Section 13.10. Expenses. Except as expressly set forth herein, each party hereto will pay all costs and expenses incident to its negotiation and preparation of this Agreement and to its performance and compliance with all agreements and conditions contained herein on its part to be performed or complied with, including the fees, expenses and disbursements of its counsel and independent public accountants.

Section 13.11. Partial Invalidity. Wherever possible, each provision hereof shall be interpreted in such manner as to be effective and valid under applicable law, but in case any one or more of the provisions contained herein shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such provision shall be ineffective to the extent, but only to the extent, of such invalidity, illegality or unenforceability without invalidating the remainder of such invalid, illegal or unenforceable provision or provisions or any other provisions hereof, unless such a construction would be unreasonable.

Section 13.12. Execution in Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be considered an original instrument, but all of which shall be considered one and the same agreement, and shall become binding when one or more counterparts have been signed by each of the parties hereto and delivered to Sellers and Buyer.

Section 13.13. Further Assurances. On and after the Closing Date each party hereto shall take such other actions and execute such other documents and instruments of conveyance and transfer as

may be reasonably requested by the other party hereto from time to time to effectuate or confirm the transfer of the Purchased Assets to Buyer in accordance with the terms of this Agreement. Notwithstanding anything in this Agreement to the contrary, this Agreement shall not constitute an agreement to assign any license, certificate, approval, authorization, agreement, contract, lease, easement or other commitment included in the Purchased Assets if an attempted assignment thereof without the consent of a third party thereto would constitute a breach thereof giving the third party a right of termination. If any such consent shall not be obtained or if any attempted assignment would be ineffective or would impair Buyer's rights under the Purchased Asset in question so that Buyer would not in effect acquire the benefit of all such rights, Sellers, to the maximum extent permitted by law and the Purchased Asset (but excluding any obligation of Sellers to offer or pay any consideration therefor), shall act after the Closing Date as Buyer's agent in order to obtain for it the benefits thereunder. Buyer and Sellers shall cooperate, to the maximum extent permitted by law and the Purchased Asset (but excluding any obligation of Sellers to offer or pay any consideration therefor), with each other in any legal and reasonable arrangement designed to provide such benefits to Buyer and to relieve Sellers from any obligation, liability or burden associated therewith.

Section 13.14. Disclaimer of Warranties. Sellers make no representations or warranties with respect to any projections, forecasts or forward-looking information provided to Buyer. There is no assurance that any projected or forecasted results will be achieved. EXCEPT AS TO THOSE MATTERS EXPRESSLY COVERED BY THE REPRESENTATIONS AND WARRANTIES IN THIS AGREEMENT AND THE CERTIFICATE DELIVERED BY SELLERS PURSUANT TO SECTION 4.4(d), SELLERS ARE SELLING THE SHARES (AND THE BUSINESS AND ASSETS OF THE COMPANIES REPRESENTED THEREBY) AND THE OTHER PURCHASED ASSETS ON AN "AS IS, WHERE IS" BASIS AND SELLERS DISCLAIM ALL OTHER WARRANTIES, REPRESENTATIONS AND GUARANTIES WHETHER EXPRESS OR IMPLIED. EXCEPT AS TO THOSE MATTERS EXPRESSLY COVERED BY THE REPRESENTATIONS AND WARRANTIES IN THIS AGREEMENT AND THE CERTIFICATE DELIVERED BY SELLERS PURSUANT TO SECTION 4.4(d), SELLERS MAKE NO REPRESENTATION OR WARRANTY AS TO MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE AND NO IMPLIED WARRANTIES WHATSOEVER. Buyer acknowledges that neither Sellers nor any of its representatives or any other Person has made any representation or warranty, express or implied, as to the accuracy or completeness of any memoranda, charts or summaries heretofore made available by Sellers or their representatives to Buyer or any other information which is not included in this Agreement or the Schedules hereto, and neither Sellers nor any of its representatives or any other Person will have or be subject to any liability to Buyer, any Affiliate of Buyer or any other Person resulting from the distribution of any such information to, or use of any such information by, Buyer, any Affiliate of Buyer or any of their agents, consultants, accountants, counsel or other representatives.

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