(a)    Purchaser has delivered to Parent a true, complete and correct copy of the fully executed debt commitment letter, together with any related fee letters (in the case of the fee letters, as may be redacted solely for confidential provisions related to fees, “flex” terms and economically sensitive terms, none of which would (i) adversely affect the conditionality, enforceability or availability of the Debt Financing to be funded on the Closing Date or (ii) cause the aggregate principal amount of the Debt Financing to be funded on the Closing Date to be insufficient for the Financing Purposes (as defined below)), dated as of the date of this Agreement, by and among the Debt Financing Sources party thereto and Purchaser, providing for debt financing as described therein (together with all exhibits, schedules and annexes thereto, the “Debt

-47-

Commitment Letter”), pursuant to which, upon the terms and subject to the conditions set forth therein, the Debt Financing Sources party thereto have agreed to lend the amounts set forth therein (the “Debt Financing”).

(b)    Purchaser has delivered to Parent a true, complete and correct copy of the fully executed equity commitment letter dated as of the date of this Agreement (together with all exhibits, schedules and annexes thereto, the “Equity Commitment Letter” and, together with the Debt Commitment Letter, the “Commitment Letters”), by and between the Purchaser Sponsors and Purchaser, pursuant to which the Purchaser Sponsors have agreed, subject to the terms and conditions thereof, to invest in Purchaser the amounts set forth therein (the “Equity Financing” and, together with the Debt Financing, the “Financing”). The Equity Commitment Letter provides that Parent is an express third-party beneficiary of, and is entitled to enforce, the Equity Commitment Letter.

(c)    As of the date hereof, the Debt Commitment Letter is in full force and effect and constitutes the valid, binding and enforceable obligation of Purchaser, and, to the Knowledge of Purchaser, the other parties thereto, enforceable in accordance with the terms thereof, subject to the Enforceability Exceptions. As of the date hereof, the Equity Commitment Letter is in full force and effect and constitutes the valid, binding and enforceable obligation of Purchaser, and, to the Knowledge of Purchaser, each Purchaser Sponsor, enforceable in accordance with the terms thereof, subject to the Enforceability Exceptions. There are no conditions precedent related to the funding of the full amount of the Debt Financing or Equity Financing, as applicable, other than the conditions precedent expressly set forth in the applicable Commitment Letter. Except as expressly permitted under Section 6.16(b), as of the date hereof, the Commitment Letters have not been amended or modified in any manner and the respective commitments contained therein have not been terminated, reduced, withdrawn or rescinded in any respect, and, no such termination, reduction, withdrawal or rescission is contemplated by Purchaser or the Purchaser Sponsor or any other party thereto. As of the date hereof, Purchaser is not in default of or breach under the terms and conditions of any of the Commitment Letters, and as of the date hereof, no event has occurred that, with or without notice, lapse of time or both, would or would reasonably be expected to constitute a default or breach or a failure to satisfy a condition under the terms and conditions of any of the Commitment Letters.

(d)    Subject to the satisfaction of the conditions set forth in Section 9.1 and Section 9.2, Purchaser has no reason to believe that (i) any of the conditions precedent expressly set forth in the Commitment Letters will not be satisfied on or prior to the Closing Date or (ii) the Financing in the aggregate amounts necessary (together with other cash and cash equivalents of the Transferred Entities or otherwise available to the Purchaser) to satisfy the Financing Purposes (as defined below) will not be available to Purchaser on the Closing Date. Notwithstanding anything elsewhere in this Agreement to the contrary, Purchaser acknowledges that Purchaser’s obligations under this Agreement are not subject to any conditions regarding Purchaser’s, its Affiliates’, or any other Person’s (including, for the avoidance of doubt, Parent or any of its Subsidiaries) ability to obtain the Equity Financing, Debt Financing or any other financing transaction, or the availability or receipt of the proceeds of any of the foregoing, for the consummation of the transactions contemplated hereby.

-48-

(e)    There are no side letters, understandings or other agreements or arrangements of any kind relating to any of the Commitment Letters or the Financing that could adversely affect the conditionality, amount, timing, availability or termination of the Financing, other than as expressly set forth in the Commitment Letters. Purchaser or an Affiliate of Purchaser on its behalf has fully paid any and all commitments or other fees and amounts required by the Commitment Letters to be paid by Purchaser on or prior to the date of this Agreement.

(f)    The Financing, when funded in accordance with the Commitment Letters (including after given effect to any “flex” provisions) (together with other cash and cash equivalents of the Transferred Entities or otherwise available to the Purchaser), will provide Purchaser with cash proceeds on the Closing Date sufficient to enable Purchaser to perform all of its payment obligations in accordance with Section 2.3(b)(ii) and, if applicable, Section 2.7 (the “Financing Purposes”). Purchaser has no reason to believe that the representations and warranties contained in the immediately preceding sentence will not be true at and as of the Closing Date.

(g)    Assuming the accuracy of the representations and warranties of the Sellers and Transferred Entities set forth in Articles III and IV, immediately after giving effect to the consummation of the Sale, Purchaser and its Subsidiaries, taken as a whole, will be Solvent. For purposes of this Section 5.6(g), “Solvent” shall mean, with respect to Purchaser and its Subsidiaries, taken as a whole, that: (i) the fair saleable value (determined on a going concern basis) of the assets of Purchaser and its Subsidiaries, taken as a whole, shall be greater than the total amount of the Liabilities of Purchaser and its Subsidiaries, taken as a whole, (ii) Purchaser and its Subsidiaries, taken as a whole, shall be able to pay their debts and obligations in the Ordinary Course of Business as they become due, and (iii) Purchaser and its Subsidiaries, taken as a whole, shall have adequate capital to carry on their businesses and all businesses in which they are about to engage. Purchaser does not currently intend to engage in any transaction following the Closing that would negatively impact the solvency of the Transferred Entities, including any transaction to sell any material assets of the Business after the Closing.

Section 5.7    Guaranty. Concurrently with the execution of this Agreement, the Purchaser Sponsors have delivered to Parent a true, complete and correct copy of the executed Limited Guaranty. The Limited Guaranty is in full force and effect and constitutes the valid, binding and enforceable obligation of the Purchaser Sponsors in favor of Parent, enforceable by Parent in accordance with its terms, subject to the Enforceability Exceptions. The Purchaser Sponsors are not in default of or breach under any of the terms or conditions of the Limited Guaranty, and no event has occurred that, with or without notice, lapse of time or both, would or would reasonably be expected to constitute a default of or breach or a failure to satisfy a condition under the terms and conditions of the Limited Guaranty. The Purchaser Sponsors have access to sufficient capital to satisfy the full amount of the guaranteed obligations under the Limited Guaranty in full.

Section 5.8    Investment Decision. Purchaser is acquiring the Transferred Equity Interests for investment and not with a view toward or for the sale in connection with any distribution thereof, or with any present intention of distributing or selling such Transferred Equity Interests. Purchaser acknowledges that the Transferred Equity Interests have not been registered under the Securities Act or any other federal, state, foreign or local securities Law, and agrees that such Transferred Equity Interests may not be sold, transferred, offered for sale, pledged, distributed,

-49-

hypothecated or otherwise disposed of without registration under the Securities Act, except pursuant to an exemption from such registration available under the Securities Act, and in compliance with any other federal, state, foreign or local securities Law, in each case, to the extent applicable.

Section 5.9    Independent Investigation. Purchaser has conducted its own independent investigation, review and analysis of the business, operations, assets, liabilities, results of operations, financial condition, technology, management and prospects of the Transferred Entities and the Business, which investigation, review and analysis was done by Purchaser and its Representatives.

Purchaser further acknowledges that no representative of the Sellers, the Transferred Entities or their respective Affiliates has any authority, express or implied, to make any representations, warranties or agreements not specifically set forth in this Agreement, the Ancillary Agreements and certificates delivered hereunder and thereunder and subject to the limited remedies herein and therein provided. Purchaser acknowledges that, should the Closing occur, Purchaser shall acquire the Transferred Entities and the Business without any representation or warranty as to merchantability or fitness thereof for any particular purpose, in an “as is” condition and on a “where is” basis, except as otherwise expressly set forth in this Agreement.

For

-54-

the avoidance of doubt, nothing in this Section 6.2(b) or Section 6.6 shall (i) prohibit CCMP Capital Partners or INEOS Limited from making disclosures regarding the transactions contemplated hereby on a confidential basis to their respective equityholders, investors or prospective investors, and (ii) prohibit Parent from making disclosures in accordance with, and as contemplated by, Section 6.6 hereof.

Additionally, subject to the terms and conditions of this Agreement, each of Parent and Purchaser shall use reasonable best efforts to take, or cause to be taken, all actions, and do, or cause to be done, all things necessary, proper or advisable under any applicable Laws to fulfill all conditions precedent to this Agreement and shall use reasonable best efforts not to take any action after the date of this Agreement that would reasonably be expected to materially delay the obtaining of, or result in not obtaining, any consent, clearance, expiration or termination of a waiting period, authorization, Order or approval of, or any exemption by, any Governmental Entity necessary to be obtained at or prior to the Closing.

(b)    Prior to the Closing, to the extent not prohibited by applicable Law, Purchaser and Parent shall each keep the other reasonably apprised of the status of matters relating to the completion of the Sale and the other transactions contemplated by this Agreement and, subject to the terms and conditions of this Agreement, work cooperatively in connection with obtaining all required consents, clearances, expirations or terminations of waiting periods, authorizations, Orders or approvals of, or any exemptions by, any Governmental Entity. In that regard, prior to the Closing, subject to the Confidentiality Agreement and Section 6.2, to the extent not prohibited by applicable Law, each of Parent and Purchaser shall promptly consult with the other party to provide any reasonably necessary information with respect to (and, in the case of correspondence, provide the other party (or their counsel) copies of) all filings made by such party with any Governmental Entity or any other information supplied by such party to, or correspondence with, a Governmental Entity in connection with this Agreement, the Sale and the other transactions contemplated by this Agreement. Subject to the Confidentiality Agreement and Section 6.2, to the extent not prohibited by applicable Law, each party to this Agreement shall promptly inform the other party to this Agreement, and if in writing, furnish the other party with copies of (or, in the case of oral communications, advise the other party of) any material communication from any Governmental Entity or other such Person regarding the Sale or the other transactions contemplated by this Agreement, and permit the other party to review and discuss in advance, and consider in good faith the views of the other party in connection with, any proposed written or oral communication or submission with or to any such Governmental Entity or other such Person. If any party to this Agreement or any representative of such party receives a request for additional information or documentary material from any Governmental Entity with respect to the Sale or the other transactions contemplated by this Agreement, then such party will make, or cause to be made, promptly and after consultation with the other party to this Agreement, an appropriate response in compliance with such request. Purchaser, on one hand, and Parent, on the other hand, shall not participate in any meeting with any Governmental Entity in connection with this Agreement or the Sale, or with any other Person in connection with any Action by a private party relating to any Competition Laws in connection with this Agreement or the Sale, or make oral submissions at meetings or in telephone or other conversations, unless it consults with the other party in advance and, to the extent not prohibited by such Governmental Entity, gives the other party the opportunity to attend and participate thereat. Purchaser and Parent may, as each deems in good faith to be advisable and necessary, reasonably designate any competitively

sensitive material provided to the other party under this Agreement as “outside counsel only.” Such designated materials and any materials provided by Purchaser to Parent or by Parent to Purchaser pursuant to this Section 6.3, and the information contained therein, shall be given only to the outside legal counsel of the recipient and shall not be disclosed by such outside counsel and in-house counsel to employees (other than in-house counsel), officers or directors of the recipient unless express permission is obtained in advance from the source of the materials (Purchaser or Parent, as the case may be) or its legal counsel; it being understood that materials provided pursuant to this Agreement may be redacted (i) to remove references concerning the valuation of the Business, (ii) as necessary to comply with contractual confidentiality arrangements and (iii) as necessary to address reasonable privilege concerns.

(c)    Purchaser and Parent shall file or cause to be filed, as promptly as practicable, but in any event no later than five (5) Business Days after the date of this Agreement, notifications under the HSR Act, and Purchaser and Parent shall file or cause to be filed, no later than ten (10) Business Days after the date of this Agreement, any other filings and/or notifications (or where applicable, drafts thereof) required under applicable Competition Laws provided that Parent supplies the information required to be provided by it for the filings reasonably in advance of the filing deadline.

(d)    Subject to the terms and conditions of this Agreement, Purchaser shall use its reasonable best efforts to resolve such objections, if any, as may be asserted by any Governmental Entity with respect to the Sale and the other transactions contemplated by this Agreement under any Laws that are designed or intended to prohibit, restrict or regulate actions having the purpose or effect of monopolization or lessening of competition through merger or acquisition or restraint of trade. In connection therewith, if any Action is instituted challenging the Sale or the other transactions contemplated by this Agreement as violative of any applicable Competition Laws, Purchaser shall use its reasonable best efforts to initiate and/or participate in any Actions, whether judicial or administrative, to (i) oppose or defend against any Action by any Governmental Entity to prevent or enjoin the consummation of the Sale or the other transactions contemplated by this Agreement and/or (ii) take such action as necessary to overturn any regulatory Action by any Governmental Entity to block consummation of the Sale or the other transactions contemplated by this Agreement, including by defending any such Action brought by any Governmental Entity to avoid the entry of, or to have vacated, overturned or terminated, including by appeal if necessary, any Order that makes illegal or prohibits the consummation of the Sale or the other transactions contemplated by this Agreement resulting from any such Action.

(e)    Notwithstanding any other provision of this Agreement, Purchaser shall take all actions reasonably necessary to avoid or eliminate each and every impediment under any Competition Laws so as to enable the Closing to occur as promptly as practicable (and in any event no later than the Outside Date), including (i) agreeing to, committing to and effecting, by consent decree, hold separate Order, or otherwise, the sale, divestiture or disposition of any businesses, product lines or assets of the Transferred Entities, Purchaser, and their respective Subsidiaries, and (ii) otherwise taking or committing to take actions that after the Closing would limit Purchaser’s, the Transferred Entities’ or their respective Subsidiaries’ freedom of action with respect to, or its or their ability to retain, any businesses, product lines or assets of the Transferred Entities, Purchaser, and their respective Subsidiaries. In that regard Purchaser shall sell, dispose of, hold separate, or otherwise take or commit to take any action that limits its freedom of action with

-57-

respect to, or Purchaser’s Subsidiaries’ ability to retain, any of the businesses, product lines or assets of the Transferred Entities, Purchaser, or any of their respective Subsidiaries. No actions required to be taken pursuant to this Section 6.3(e) shall be considered for purposes of determining whether a Business Material Adverse Effect has occurred or may occur.

(f)    Whether or not the Sale is consummated, Purchaser shall be responsible for all filing fees to obtain any consent, clearance, expiration or termination of a waiting period, authorization, Order or approval pursuant to this Section 6.3.

(a)    From and after the Closing, Parent shall indemnify and hold harmless Purchaser and the Transferred Entities against any Liabilities that Purchaser or any of the Transferred Entities suffer, incur or are liable for by reason of or arising out of or in consequence of any Transferred Entity being a party to, any guarantee, indemnity, surety bond, letter of credit, letter of comfort, commitment or other similar obligation relating to the Retained Businesses that is listed on Section 6.9(a) of the Parent Disclosure Schedule (collectively, the “Guarantees”).

(b)    Without limiting Section 6.9(a) in any respect, Parent shall use commercially reasonable efforts, at its sole expense, to cause itself or its Affiliates to be substituted in all respects for any Transferred Entity, and for such Transferred Entity to be released, effective as of the Closing, in respect of, or otherwise terminate (and cause such Transferred Entity to be released in respect of), all obligations of the Transferred Entities under each Guarantee.

The members of the Parent Group may, to be effective at the Closing, amend any insurance policies and ancillary arrangements in the manner they deem appropriate to give effect to this Section 6.10; provided, that Parent shall not, and shall cause the Parent Group not to, take any action that would cause the Transferred Entities to no longer be eligible for coverage under the Retained Policies in respect of Pre-Closing Occurrences. Subject to the rest of this Section 6.10, from and after the Closing, Purchaser shall be responsible for securing all insurance it considers appropriate for the Transferred Entities and the Business. The parties acknowledge that the Transferred Entities may be entitled to the benefit of coverage under the insurance policies of the Parent Group (the “Retained Policies”) with respect to acts, facts, circumstances or omissions occurring prior to Closing (“Pre-Closing Occurrences”). For any Pre-Closing Occurrences, from and after the Closing, Parent will direct such carriers to provide the Transferred Entities with access to the Retained Policies and shall reasonably cooperate with Purchaser and the Transferred Entities and take commercially reasonable actions as may be necessary or advisable to assist the Transferred Entities in submitting, and to provide support with respect to, such claims to which such policies are responsive. Parent hereby authorizes Purchaser to report any and all Pre-Closing Occurrences arising in connection with the Transferred Entities to the applicable insurance providers of the Parent Group to the extent permitted under the applicable Retained Policy, and where not permitted, Parent agrees, upon receipt of a written request by Purchaser, to use commercially reasonable efforts to make such report on Purchaser’s behalf. With respect to claims for Pre-Closing Occurrences made pursuant to this Section 6.10 (or pending as of the date of this Agreement), (i) if reported to the applicable insurance provider by Purchaser, Purchaser shall promptly notify Parent’s corporate insurance department of such claims, (ii) whether such Pre-Closing Occurrence was reported to the applicable insurance provider by Purchaser or Parent or any of their respective Affiliates, (A) Parent shall provide Purchaser with a copy of the applicable Retained Policy and Purchaser shall, and shall cause its Affiliates to, comply with the terms of the applicable Retained Policy and (B) each party shall, and shall cause its Affiliates to, use commercially reasonable efforts to obtain the benefit of the applicable insurance coverage and pay such benefit, if any, to Purchaser.

(b)    Notwithstanding anything to the contrary in this Agreement, Parent shall, and shall cause its Representatives to, cooperate with Purchaser and its Representatives and use their respective reasonable best efforts to secure for the Business, effective as of the Closing Date, separate policies with substantially similar terms (including the same level of coverage and no less favorable deductibles) as the following policies (which policies will be retained by the Retained Businesses): (i) Premises Pollution Liability (US), dated July 18, 2019 to July 18, 2022, by Illinois Union Insurance Company, no.

(a)    Purchaser shall use its reasonable best efforts to take, or cause to be taken, all actions and do, or cause to be done, all things necessary or advisable to obtain funds sufficient (when taken together the unrestricted cash and cash equivalents of the Transferred Entities) to fund the Financing Purposes, in each case, on or prior to the Closing Date, including, without limitation (i) maintaining in effect the Commitment Letters and any Definitive Debt Financing Agreements and complying with its obligations thereunder, (ii) satisfying on a timely basis, and in a manner that will not impede the ability of the parties hereto to consummate the Sale promptly upon the Closing Date, all conditions to the funding of the Financing set forth in the Commitment Letters and the Definitive Debt Financing Agreements that are within its control or the control of any Affiliate of the Purchaser, (iii) using reasonable best efforts to negotiate and enter into at or prior to the Closing definitive debt financing agreements on the terms and conditions contemplated by the Debt Commitment Letter (including, if necessary, any “flex” provisions) (the “Definitive Debt Financing Agreements”), and (iv) consummate the Debt Financing at or prior to the Closing.

(b)    Prior to the Closing, Purchaser shall not, and shall cause its Affiliates not to, agree to or permit any termination, amendment, replacement, supplement or other modification of, or waive any of its rights under, the Commitment Letters or Definitive Debt Financing Agreements without Parent’s prior written consent; provided that Purchaser may, without Parent’s prior written consent: (i) enter into any amendment, replacement, supplement, termination or other modification to or waiver of any provision of the Debt Commitment Letter or Definitive Debt Financing Agreements that would not, and would not reasonably be expected to, (A) reduce the amount of the Debt Financing contemplated by the Debt Commitment Letter (including by increasing the amount of fees to be paid or original issue discount beyond what is contemplated by the “flex” provisions of the fee letter related to the Debt Commitment Letter) to an amount that is not sufficient for the Financing Purposes unless such amount is replaced by any Alternative Financing, (B) adversely affect the ability of Purchaser to enforce its rights against any other party to the Debt Commitment Letter or the Definitive Debt Financing Agreements, in each case, as so amended, replaced, supplemented or otherwise modified, relative to the ability of Purchaser to enforce its rights against the other parties to the Debt Commitment Letter as in effect on the date hereof, (C) prevent, materially delay or impede the consummation of the Sale, the Debt Financing on the Closing Date or the other transactions contemplated by this Agreement or delay the Closing, or (D) impose any new or additional conditions, or otherwise expands any of the conditions, to the availability and funding of Debt Financing as contemplated by the Debt Commitment Letter, and (ii) amend, replace, supplement or otherwise modify the Debt Commitment Letter solely to add lenders, lead arrangers, book runners, syndication agents or similar entities that have not executed the Debt Commitment Letter as of the date of this Agreement, with any other amendment, replacement, supplement or modification related thereto subject to provisions of the foregoing

-74-

clauses (A) through (D). Upon any such amendment, replacement, supplement, modification or waiver, the terms “Debt Commitment Letter” and “Definitive Debt Financing Agreement” shall mean the Debt Commitment Letter or Definitive Debt Financing Agreement, as applicable, as so amended, replaced, supplemented or modified. Purchaser shall promptly deliver to Parent copies of any such amendment, replacement, supplement or other modification of the Debt Commitment Letter and/or any such waiver of a provision of the Debt Commitment Letter.

(c)    If all or any portion of the Debt Financing becomes unavailable, or the Debt Commitment Letter or any of the Definitive Debt Financing Agreements shall be withdrawn, repudiated, terminated or rescinded, regardless of the reason therefor, then Purchaser shall (i) use reasonable best efforts to arrange and obtain, as promptly as practicable, from the same and/or alternative financing sources, alternative financing in an amount sufficient (when taken together the unrestricted cash and cash equivalents of the Transferred Entities and any remaining portion of the Debt Financing available) to fund the Financing Purposes upon terms and conditions not materially less favorable, taken as a whole, to Purchaser than those in the Debt Commitment Letter (including, for the avoidance of doubt, any related “flex” provisions), and (ii) promptly notify Parent of such unavailability and the reason therefor. In the event any alternative financing is obtained in accordance with this Section 6.16(c) (“Alternative Financing”), references in this Agreement to the “Debt Financing” shall also be deemed to refer to such Alternative Financing, and if one or more commitment letters or definitive financing agreements are entered into or proposed to be entered into in connection with such Alternative Financing, references in this Agreement to the “Debt Commitment Letter” and the “Definitive Debt Financing Agreements” shall also be deemed to refer to such commitment letters and definitive financing agreements relating to such Alternative Financing, and all obligations of Purchaser pursuant to this Section 6.16 shall be applicable thereto to the same extent as Purchaser’s obligations with respect to the Debt Financing.

(b)    Effective as of the Closing Date, or such later date as set forth in the Transition Services Agreement, and except as may be expressly contemplated by the Transition Services Agreement or as otherwise agreed to between Sellers and the Purchaser, Parent shall or shall cause its Affiliates to take such action necessary so that the Transferred Entities shall cease being participating employers in, and any Transferred Business Employee shall cease being an active participant in or accruing any benefit or compensation under, each Retained Benefit Plan; provided that the Seller and the Purchaser hereby agree that any Transferred Business Employee who became disabled prior to the Closing shall be eligible to receive long-term disability benefits under the long-term disability policy (in accordance with such policy’s terms) covering such employee immediately prior to the Closing. With respect to any Retained Benefit Plans, Purchaser shall be solely responsible for any and all obligations under Section 4980B of the Code with respect to all “M&A qualified beneficiaries” as defined in Treasury Regulation Section 54.4980B-9.

-85-

(c)    Purchaser shall not assume any obligations under, or Liabilities with respect to, or receive any right or interest in any trusts relating to, any assets of or any insurance, administration or other contracts, or related obligations pertaining to, any Retained Benefit Plan.

Section 7.7    Work Visas. Parent shall, or shall cause its Affiliates to, use commercially reasonable efforts to ensure that any Transferred Entity Employee who is a foreign national who requires a visa in order to work for the Transferred Entities or the Business in his or her current position may continue to work in such position as a Transferred Business Employee on the Closing Date.

Section 7.8    No Third-Party Beneficiaries.

ARTICLE VIII

TAX MATTERS

Section 8.1    Purchase Price Allocation.

(a)    For all U.S. federal (and applicable state and local) and non-U.S. Tax purposes, Parent and Purchaser agree to (and agree to cause their respective Affiliates to) allocate the Final Purchase Price and any other amounts treated as consideration for Tax purposes among the Transferred Entities and/or the assets of the Transferred Entities in accordance with the principles set forth on Exhibit E attached hereto (the “Purchase Price Allocation Schedule”).

(b)    No later than one hundred and twenty (120) days after the date on which the Final Purchase Price is finally determined pursuant to Section 2.7, Purchaser shall deliver to Parent a proposed allocation of the portion of the Final Purchase Price and any other items that are treated as additional consideration for Tax purposes that is allocated to the U.S. Transferred Entities among the assets of the U.S. Transferred Entities in accordance with Section 1060 of the Code and

-86-

the Treasury Regulations promulgated thereunder (“Purchaser’s Allocation”). If Parent disagrees with Purchaser’s Allocation, Parent may, within thirty (30) days after delivery of Purchaser’s Allocation, deliver a notice (“Allocation Notice”) to Purchaser to such effect, specifying those items as to which Parent disagrees and setting forth Parent’s proposed allocation. If the Allocation Notice is duly and timely delivered, the parties shall negotiate in good faith to resolve any such dispute. If within twenty (20) days, Parent and Purchaser are unable to resolve any disagreement regarding the Allocation Notice, neither the Purchaser nor Parent shall be bound by Purchaser’s Allocation and each party shall be entitled to file all Tax Returns, including IRS Form 8594, without regard to Purchaser’s Allocation or the Allocation Notice, provided, however, that in all cases, for the avoidance of doubt, the parties shall be bound to the terms of Section 8.1(a) and the Purchase Price Allocation Schedule. The allocation, (i) as prepared by Purchaser if no Parent’s Allocation Notice has been timely given with respect thereto or (ii) if Purchaser and Parent have reached an agreement within the applicable twenty (20) day period regarding the disputed item(s) in an Allocation Notice, as adjusted and finally resolved by the parties pursuant to this Section 8.1(b) (the “Allocation”), shall be conclusive and binding on the parties. The Allocation, if any, shall be adjusted, as necessary, to reflect any subsequent payments treated as adjustments to the Final Purchase Price or with respect to any other adjustments to the purchase price for Tax purposes in accordance with the procedures set forth in this Section 8.1(b). Any such adjustment shall be allocated, consistent with this Section 8.1(b) and the Purchase Price Allocation Schedule, to the Transferred Entities and/or assets of the Transferred Entities to which such adjustment is attributable.

(c)    Parent and the Purchaser shall (and shall cause their respective Affiliates to) (i) prepare and file all Tax Returns, in a manner consistent with the Purchase Price Allocation Schedule and the Allocation, if any (and any adjustments thereto) and (ii) not take any position inconsistent therewith on any Tax Return or in connection with any Tax Proceeding, in each case, except to the extent otherwise required pursuant to a “determination” (within the meaning of Section 1313(a) of the Code or any similar provision of state, local or non-U.S. Law). In the event that the Purchase Price Allocation Schedule or the Allocation, if any, is disputed by any Taxing Authority, the party receiving notice of such dispute shall promptly notify the other party in writing of such notice and resolution of the dispute. For the avoidance of doubt, the parties shall not be bound by the Purchase Price Allocation Schedule or the Allocation, if any, for any non-Tax purposes.

Section 8.2    Tax Indemnification.

(a)    From and after the Closing, solely to the extent any such amount of Tax or Loss was not included in the calculation of the Final Purchase Price (as an item included in Working Capital, the Closing Indebtedness Amount, or the Closing Transaction Expenses Amount), Parent shall indemnify and hold harmless the Purchaser Indemnitees with respect to any Losses incurred or sustained by, or imposed upon any such Purchaser Indemnitee or any of its beneficial owners as a result of, arising out of or relating to, without duplication, the amount of (A) Taxes incurred by, or imposed on any of the Transferred Entities (or with respect to a Transferred Entity, to the extent any such Tax by operation of Law is payable by another Transferred Entity including as a result of being a flowthrough or partnership for applicable Tax purposes) in a taxable period (or portion thereof) ending on or prior to the Closing Date that resulted directly from (and that would not have been incurred but for) (i) the consummation of the steps constituting the Pre-Closing

-87-

Restructuring, including, for the avoidance of doubt, any sales, use, transfer, real property transfer, registration, documentary, conveyance, franchise, goods and services, stamp, value added or similar Taxes and related fees and costs imposed on or payable in connection with the Pre-Closing Restructuring, (ii) any “de-grouping” or similar charges payable as a result of the transactions contemplated by this Agreement and any ancillary agreement (including the Pre-Closing Restructuring), and (iii) settling, eliminating or cancelling any intercompany accounts or arrangements as required by Section 6.7 or Section 6.8 and (B) any Income Taxes of Purchaser (or any of the Purchaser Indemnitees or their beneficial owners) pursuant to Section 951 or 951A of the Code relating to a Transferred Entity to the extent allocable to a Pre-Closing Tax Period applying the principles of Section 8.2(e) (and taking into account Section 250 of the Code and assuming, for this purpose, and for purposes of determining offsetting Tax Benefits pursuant to Section 8.2(c) with respect thereto that the taxable year of any Transferred Entity that is a “controlled foreign corporation” within the meaning of Section 957 of the Code shall be deemed to terminate as of the Closing), but only to the extent such Income Taxes arise from and would not have been incurred but for the consummation of the steps constituting the Pre-Closing Restructuring. For the avoidance of doubt, Parent shall not be required to indemnify any Purchaser Indemnitee in respect of any Taxes incurred by Purchaser’s beneficial owners pursuant to Section 951 or 951A of the Code, except in connection with Section 8.2(a)(B).

(b)    Without duplication of the amounts described in Section 8.2(a), from and after the Closing, through the sixth (6th) year anniversary of the Closing Date, Parent shall indemnify and hold harmless the Purchaser Indemnities with respect to any Losses incurred or sustained by, or imposed upon any such Purchaser Indemnitee as a result of, arising out of or relating to, without duplication, the amount of (i) any Income Taxes of the Transferred Entities (or with respect to a Transferred Entity, to the extent any such Tax by operation of Law is payable by another Transferred Entity including as a result of being a flowthrough or partnership for applicable Tax purposes) for a Pre-Closing Tax Period, (ii) any Income Taxes of any Person (other than any of the Transferred Entities) for which any of the Transferred Entities is or becomes liable (x) pursuant to Treasury Regulation 1.1502-6 (or any analogous provision under state, local, or non-U.S. Law) resulting from being a member of a combined, affiliated, consolidated, unitary, integration or similar Tax group with such Person prior to the Closing, (y) as transferee or successor to such Person under Law as a result of an event or a transaction occurring prior to the Closing Date, and (z) by Contract entered into prior to the Closing (including the agreement on Section 6.21(a) of the Parent Disclosure Schedule), other than any leasing, employment, credit or commercial Contracts entered into in the Ordinary Course of Business, and (iii) any Transfer Taxes that are the obligation of the Seller pursuant to Section 8.9, in each case, only to the extent any such amount was not included in the calculation of the Final Purchase Price (as an item included in Working Capital, the Closing Indebtedness Amount, or the Closing Transaction Expenses Amount). The delivery of a written notice of any indemnification claim submitted in good faith including in respect of a potential liability in connection with an ongoing but unresolved Action or other assertion of liability by a Governmental Entity or other third party in respect of Taxes under this Section 8.2(b) prior to the sixth (6th) anniversary of the Closing Date will extend the survival period of with respect to such claim through the date such claim is conclusively resolved.

(c)    Notwithstanding the foregoing or anything to the contrary in this Agreement, any amounts paid or indemnified by Parent pursuant to this Agreement shall be net of any Tax benefits actually realized with respect to such Losses (in the year of the Loss or the

-88-

succeeding two (2) years (a “Tax Benefit”)). Any such Tax Benefit shall, if applicable, be calculated (X) on a “with and without” basis, (Y) on a stand-alone basis assuming the operations of Purchaser and the Transferred Entities are the only relevant operations, and excluding the effect of any investments, activities, or operations of (x) any additional Subsidiaries of Purchaser or any Affiliates of Purchaser (in each case, other than the Transferred Entities) or (y) any Purchaser Indemnitee (or any of their Affiliates), provided, in each case, that the effect of any indebtedness actually incurred by Purchaser (or its Affiliates) to consummate the purchase of the Transferred Companies hereunder shall be taken into account and (Z) netting the effect of any actual Tax cost or detriment resulting therefrom in the year of the Loss or the succeeding two (2) years. For the avoidance of doubt, to the extent that any payment under this Section 8.2 is treated as an adjustment to the purchase price for Tax purposes, the portion of any such payment so treated shall not be treated as a “Tax Benefit.”

(d)    Notwithstanding the foregoing, or anything to the contrary in this Agreement, Parent and its Affiliates shall have no Liability under this Agreement in favor of any of the Purchaser Indemnitees solely to the extent such Liability arose from or in connection with any breach by Purchaser or any of its Affiliates of the obligations set forth in this Agreement (including Section 8.8 of this Agreement) and would not have arisen but for such breach. In addition, notwithstanding anything to the contrary in this Agreement, any indemnification obligations of Parent to the Purchaser Indemnitees shall be subject to the limitation set forth in Section 8.2(d) of the Parent Disclosure Schedules.

(e)    For purposes of this Section 8.2, any “Losses” and any “Income Taxes” of any Purchaser Indemnitee or any of its owners shall be calculated (a) on a stand-alone basis assuming the operations of Purchaser and the Transferred Entities are the only relevant operations, and excluding the effect of any other investments, activities, or operations of (x) any additional Subsidiaries of Purchaser or any Affiliates of Purchaser (in each case, other than the Transferred Entities) or (y) any Purchaser Indemnitee (or any of their Affiliates), and (b) assuming that the percentage of any income required to be included by Purchaser’s beneficial owners pursuant to Section 951 or 951A of the Code as shown on Section 8.2(e) of the Parent Disclosure Schedule, as such schedule may be reasonably updated by Purchaser prior to the Closing Date is allocable to Persons that are each treated as a “United States shareholder” within the meaning of Section 951(b) of the Code and are each classified as a corporation for U.S. federal income tax purposes. For the avoidance of doubt, a Tax shall be considered a Loss incurred or sustained at the time that it has been assessed (notwithstanding that it may be subject to objection or appeal), to the extent that a Governmental Authority is permitted to take collection action in respect of such Tax or an amount has been garnished and applied towards such Tax, as applicable. Notwithstanding the foregoing or anything to the contrary in this Agreement, any Losses in respect of Taxes or Tax Returns indemnified by Parent pursuant to this Agreement shall be calculated net of any amounts recovered by a Purchaser Indemnitee from a Governmental Entity or other third party (including an insurer) in respect of such Loss net of costs, expenses or Taxes incurred by the Purchaser Indemnitee in connection therewith (and to the extent such recovery is received by a Purchaser Indemnitee after Parent has satisfied any Loss, such Purchaser Indemnitee shall promptly pay (or cause to be paid) over to the Parent the amount of any such recovery.

-89-

Section 8.3    Cooperation and Exchange of Information. Each party to this Agreement shall, and shall cause its Affiliates to, provide to the other party to this Agreement such cooperation, documentation and information as either of them reasonably may request (and at the reasonable expense of the requesting party) in (a) filing any Tax Return, amended Tax Return or claim for refund, (b) determining a Liability for Taxes or a right to refund of Taxes or (c) conducting any Tax Proceeding. Such cooperation and information shall include providing copies of all relevant portions of relevant Tax Returns, together with all relevant portions of relevant accompanying schedules and relevant work papers, relevant documents relating to rulings or other determinations by taxing authorities and relevant records concerning the ownership and Tax basis of property and other information, which any such party may possess. Each party shall make its employees reasonably available on a mutually convenient basis at the requesting party’s reasonable cost to provide an explanation of any documents or information so provided. Notwithstanding anything in this Agreement, none of the parties to this Agreement or any of their respective Affiliates shall be required to provide any document pursuant to this Section 8.3 that such party reasonably believes is entitled to legal or accounting privilege that could be waived by such provisions and notwithstanding anything to the contrary in this Agreement, (x) neither Parent nor any of the Sellers shall be required to provide any Person with any Tax Return or copy of any Tax Return of (i) Parent or a member of the Parent Group or (ii) a consolidated, combined, affiliated or unitary group that includes any member of the Parent Group and (y) none of Purchaser or any of its Affiliates shall be required to provide any Person with any Tax Return or copy of any Tax Return of (i) Purchaser or any member a consolidated, combined, affiliated or unitary group that includes Purchaser (other than any of the Transferred Entities) or (ii) a consolidated, combined, affiliated or unitary group that includes any of the Transferred Entities that relates to any taxable period beginning after the Closing. Each party shall use commercially reasonable efforts to retain all material Tax Returns, schedules and work papers, and all material records and other documents relating to Tax matters, of the relevant entities for their respective Tax periods ending on or prior to the Closing Date until the expiration of the statute of limitations for the Tax periods to which the Tax Returns and other documents relate.

Section 8.4    Preparation and Filing of Returns. Parent shall prepare (or cause to be prepared) all Income Tax Tax Returns of the Transferred Entities for (A) any Tax period ending on or prior to the Closing Date or (B) Straddle Period to the extent such Straddle Period Tax Return is described on Section 8.4 of the Parent Disclosure Schedule (as may be reasonably updated by Parent prior to the Closing Date to reflect Tax Returns that would reasonably be expected to materially affect Parent’s (or its Affiliates’) U.S. federal Income Tax position as a result of the Pre-Closing Restructuring and the Post-Closing Restructuring), provided that all such Tax Returns shall be prepared in a manner consistent with (1) the Pre-Closing Restructuring (and, unless otherwise required by applicable Law, the Tax treatment outlined in Exhibit A), the Post-Closing Restructuring and the Post-Closing Restructuring Schedule, and the Purchase Price Allocation Schedule, and (2) to the extent not inconsistent with clause (1) or applicable Law, past practice (“Parent Tax Returns” which Parent Tax Returns shall include, for the avoidance of doubt, IRS Forms 5471). Not later than thirty (30) days prior to the due date (including applicable extensions) of any such Parent Tax Return, Parent shall provide Purchaser with a copy of each such Parent Tax Return for its review and shall incorporate any reasonable written comments provided by

-90-

Purchaser within fifteen (15) days of Purchaser’s receipt of such Parent Tax Return so long as such comments would not be expected to (1) have the effect of increasing Parent’s (and its Affiliates’) indemnification obligations pursuant to this Agreement, or (2) result in any non-de minimis unreimbursed cost for or non-de minimis adverse effect on Parent or any of its Affiliates except, in each case, to the extent Parent’s position is not permitted by applicable Law. Purchaser shall prepare (or cause to be prepared) all Income Tax Tax Returns of the Transferred Entities for any Straddle Period other than any Parent Tax Return (“Purchaser Tax Returns”, which Purchaser Tax Returns shall include, for the avoidance of doubt, IRS Forms 5471). Not later than thirty (30) days prior to the due date (including any applicable extensions) of any such Purchaser Tax Return, Purchaser shall provide Parent with a copy of each such Purchaser Tax Return for its review and shall incorporate any reasonable written comments provided by Parent within fifteen (15) days of Parent’s receipt of such Purchaser Tax Return so long as such comments would not reasonably be expected to result in any non-de minimis unreimbursed cost for or non-de minimis adverse effect on Purchaser or any of its Affiliates except to the extent Purchaser’s position is not permitted by applicable Law. Purchaser shall timely file or cause to be filed any such Tax Returns as finalized pursuant to the terms of this Section 8.4. The parties agree that, upon the request of Purchaser, in filing any Pass-Through Tax Return that would be governed by this Section 8.4 for the taxable year of any U.S. Transferred Entity that is a partnership for U.S. federal income Tax purposes that includes the Closing Date, the party preparing or causing to be prepared such Tax Return shall cause the relevant Transferred Entity to make an election under Code Section 754 (and the corresponding provisions of U.S. state, local or non-U.S. Tax Law) if such Transferred Entity does not already have a valid election under Code Section 754 in place. Notwithstanding the foregoing and for the avoidance of doubt, as between Parent and its Affiliates, on the one hand, and Purchaser and its Affiliates on the other, Parent shall have sole responsibility for all Tax Returns (and any Taxes thereon) and any other Tax matters with respect to the Contracts listed in Section 8.4 of the Parent Disclosure Schedule. For the avoidance of doubt, Purchaser agrees to file any Tax Returns that are not Parent Tax Returns for any Transferred Entity with respect to any Pre-Closing Tax Period in a manner that is consistent with (A) the Pre-Closing Restructuring (and, unless otherwise required by applicable Law, the Tax treatment outlined in Exhibit A), the Post-Closing Restructuring and the Post-Closing Restructuring Schedule, and the Purchase Price Allocation Schedule, and (B) to the extent not inconsistent with clause (A) or applicable Law, past practice. Notwithstanding the foregoing or anything to the contrary in this Agreement, as between Parent and its Affiliates, on the one hand, and Purchaser and its Affiliates on the other, Parent shall retain all rights and obligations over Tax matters (including any Tax Actions) with respect to the Contracts listed in Section 8.4 of the Parent Disclosure Schedule, provided that Parent and its Affiliates covenant and agree not to knowingly after due inquiry take any actions with the specific intent to breach of any of the obligations set forth in such Contracts with respect to Taxes or Tax Returns.

Section 8.5    Tax Audit. If Purchaser (which, for purposes of this first sentence of this Section 8.5, shall be deemed to include any of its Affiliates or any of the Transferred Entities) or Parent (which, for purposes of this first sentence of this Section 8.5, shall be deemed to include any of its Affiliates (other than the Transferred Entities)) receives notice of any Action in respect of any Taxes or any Tax Return of the Transferred Entities for any taxable period ending on or before the Closing Date or any Straddle Period, then such party will promptly give written notice along with copies of any assessment, notice or other document received from any Governmental Entity to the other party; provided, that the failure of such party to give such prompt notice shall

-91-

not relieve the other party of any of its obligations under this Article VIII. To the extent that portion of any such audit, investigation, or other Action is reasonably expected to relate to a Parent Tax Return or the validity of the Tax treatment of the steps contemplated by Exhibit A (the portion of each Action, a “Parent Tax Audit”), Parent will have the right, at its own expense, to control the defense of the Parent Tax Audit, provided that (A) Parent gives written notice to the Purchaser within fifteen (15) days after the Parent receives notice of the Parent Tax Audit from the Purchaser (or any of its Affiliates) or the applicable Governmental Entity, (B) Parent keeps the Purchaser reasonably informed of all material matters that come to its attention in respect of the Parent Tax Audit, (C) Parent offers Purchaser an opportunity to comment before submitting any written materials prepared or furnished in connection with such Parent Tax Audit, (D) Parent defends such Parent Tax Audit diligently and in good faith as if it were the only party in interest in connection with such Parent Tax Audit, and (E) Parent does not settle, compromise or abandon any such Parent Tax Audit without obtaining the prior written consent of the Purchaser, which consent shall not be unreasonably withheld, conditioned or delayed. The Purchaser will be entitled to participate in the defense of any Parent Tax Audit, at its own expense. Where Parent does not elect to control the defense of the Parent Tax Audit, Purchaser shall be entitled to control such Parent Tax Audit and to settle or compromise such Parent Tax Audit, without the consent of Parent. Notwithstanding the foregoing, to the extent that any audit, investigation, or other Action is reasonably expected to relate to the validity of the Tax treatment of the steps contemplated by or the Post-Closing Restructuring Schedule, Purchaser shall not settle or compromise any such audit, investigation, or other Action without the prior written consent of Parent, which consent shall not be unreasonably withheld, conditioned or delayed. In addition, with respect to any U.S. Transferred Entity that is or was a partnership for U.S. federal income Tax purposes, (i) the parties agree that an election under Section 6226 of the Code with respect to such Transferred Entity for any Tax period ending on or before the Closing Date or any Straddle Period shall be made, and (ii) at the request of the Purchaser, subject to the terms of this Section 8.5, the Parent shall (and, if applicable, shall cause its Affiliates, any Person appointed as the “partnership representative” of any of the Transferred Entities, and any Person appointed as the “designated individual” of any of the Transferred Entities to) promptly revoke the appointment, or cause the resignation, of any Person previously appointed as the “partnership representative” or the “designated individual” of any of the Transferred Entities (in each case, pursuant to Treasury Regulations Section 301.6223-1) for any Pre-Closing Tax Period (including any Straddle Period) in accordance with the procedures described in Treasury Regulations Section 301.6223-1 in connection with any Tax Proceeding with respect to any of the Transferred Entities under the Partnership Tax Audit Rules.

Section 8.6    Tax Sharing Agreements. On or before the Closing Date, the rights and obligations of the Transferred Entities pursuant to all Tax sharing agreements or arrangements (other than this Agreement), if any, to which any of the Transferred Entities, on the one hand, and any member of the Parent Group, on the other hand, are parties (provided that there are no other parties to such agreements or arrangements), shall terminate, and neither any member of the Parent Group, on the one hand, nor any of the Transferred Entities, on the other hand, shall have any rights or obligations to each other after the Closing in respect of such agreements or arrangements.

Section 8.7    Tax Treatment of Payments. Except to the extent otherwise required pursuant to a “determination” (within the meaning of Section 1313(a) of the Code or any similar provision of state, local or non-U.S. Law), Parent, Purchaser, the Transferred Entities and their respective Affiliates shall treat any and all payments under Section 2.7, Section 6.21, Section 8.2 and Section 8.10 as an adjustment to the purchase price for Tax purposes.

-92-

Section 8.8    Post-Closing Tax Covenant. The Parties agree to comply with the provisions set forth in Section 8.8 of the Parent Disclosure Schedule.

Section 8.9    Transfer Taxes. Notwithstanding anything to the contrary in this Agreement, Purchaser, on the one hand, and Sellers on the other hand, shall each pay, when due, and be responsible for, fifty (50%) percent of any, any sales, use, transfer, real property transfer, registration, documentary, conveyance, franchise, goods and services, stamp, value added or similar Taxes and related fees and costs imposed on or payable in connection with the transactions contemplated by this Agreement, excluding the Pre-Closing Restructuring (“Transfer Taxes”). The party responsible under applicable Law for filing the Tax Returns with respect to any such Transfer Taxes shall prepare and timely file such Tax Returns and promptly provide a copy of such Tax Return to the other party. Parent and Purchaser shall, and shall cause their respective Affiliates to, cooperate to timely prepare and file any Tax Returns or other filings relating to such Transfer Taxes, including any claim for exemption or exclusion from the application or imposition of any Transfer Taxes; provided that, notwithstanding any of the foregoing, neither parent nor any of their respective Affiliates shall be required to file any claim for exemption or exclusion from the application or imposition of any Transfer Taxes, or any claim for any reduction thereof, if such party reasonably determines in its sole discretion that the filing of such claim or any related action would have an adverse effect on Parent or any of its Affiliates. For the avoidance of doubt, the Closing Purchase Price set forth in this Agreement is exclusive of Transfer Taxes.

Section 8.10    Refunds. Parent shall be entitled to retain (on behalf of the Sellers), or receive prompt payment from Purchaser of, any Tax refund or credit in lieu thereof (including refunds and credits arising by reason of amended Tax Returns filed after the Closing Date or otherwise) actually realized in cash or as an amount credited against Taxes otherwise payable by any Transferred Entity with respect to any Tax period ending on or before the Closing Date, except to the extent: (i) attributable to the carryback of a net operating loss or other Tax attribute from a taxable period (or portion thereof) beginning after (or in the case of Transferred Entities that are residents of Canada for purposes of the Income Tax Act (Canada), on) the Closing Date, (ii) specifically identified and taken into account in the calculation of Working Capital or Indebtedness, (iii) received by Purchaser or any of the Transferred Entities more than eighteen (18) months after the Closing Date, or (iv) required to be paid by any of the Transferred Entities, or any of their respective Affiliates to any other Person pursuant to a Contract entered into prior to the Closing (other than this Agreement). Any amount that Parent is entitled to under this Section 8.10 shall be net of any costs, expenses or Taxes incurred by Purchaser, any Transferred Entity or any of their respective Affiliates in connection with the obtaining, receiving, or paying over any Tax refunds or credits. If Parent determines that any Transferred Entity is entitled to file or make a claim for refund or to file an amended Tax Return providing for a refund with respect to a taxable period ending on or before the Closing Date, then Purchaser will, if Parent so reasonably requests in writing within six (6) months after the Closing Date and at Parent’s upfront expense, cause the relevant Transferred Entity to file or make such claim or amended Tax Return unless doing so could reasonably be expected to have a non-de minimis adverse effect on Purchaser, any Transferred Entity, or any of their respective Affiliates.

Section 10.3    Effect of Termination.

(a)    In the event of termination of this Agreement by either or both of Parent and Purchaser pursuant to Section 10.1, but subject in all cases to the terms of this Section 10.3, this Agreement shall terminate and become void and have no effect, and there shall be no Liability on the part of any party to this Agreement, except as set forth in Section 10.3(b), as well as the Reimbursement Obligations set forth in Section 6.16(d); provided that, subject to Section 10.3(b), termination of this Agreement shall not relieve any party hereto from Liability for willful or material breach of this Agreement or willful or material failure to perform its obligations under this Agreement. Notwithstanding anything to the contrary contained herein, the Reimbursement Obligations set forth in Section 6.16(d) (Parent Cooperation) and the provisions of Section 10.1 (Termination), Section 10.2 (Notice of Termination), this Section 10.3 (Effect of Termination) and Article XI shall survive any termination of this Agreement and Purchaser and Parent shall, in all events, remain bound by and continue to be subject to the Confidentiality Agreement and nothing in this Section 10.3 shall limit the right of either party hereto to bring or maintain any Action arising out of or in connection with any breach of the Confidentiality Agreement pursuant to the terms thereof.

(b)    If this Agreement is validly terminated by Parent pursuant to Section 10.1(e) or Section 10.1(f), then Purchaser shall pay to Parent or its designee a cash amount equal to $66,000,000 (the “Termination Fee”) as set forth in this Section 10.3. In the event that the Termination Fee is payable, Purchaser (or its designee) will pay the Termination Fee to Parent by wire transfer of immediately available funds within two (2) Business Days after the date that this Agreement is so validly terminated and receipt of wire transfer instructions from Parent.

(c)    Each of the parties hereto acknowledges that (i) the agreements contained in this Section 10.3 are an integral part of the transactions contemplated by this Agreement and (ii) without these agreements, the parties hereto would not enter into this Agreement. The parties hereto acknowledge and hereby agree that the Termination Fee, if, as and when required to be paid pursuant to this Section 10.3, shall not constitute a penalty, but will be liquidated damages in a reasonable amount that will compensate Parent for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Sale, which amount would otherwise be impossible to calculate with precision. Notwithstanding anything to the contrary set forth in this Agreement, the parties hereto agree that in no event shall Purchaser be required to pay the Termination Fee on more than one occasion.

-97-

(d)    Subject to and without limiting Section 10.3(e), following any termination of this Agreement in accordance with Section 10.1, the right of Parent to collect the Termination Fee pursuant to Section 10.3(b) (if payable pursuant to the terms thereof) shall be the sole and exclusive remedy (whether at law, in equity, in contract, in tort or otherwise) of Parent or any of its Subsidiaries (including any Transferred Entity), CCMP Capital Partners or INEOS Limited or any of their respective Affiliates, Representatives, former, current and future shareholders, members, managers, general or limited partners, management companies, investment vehicles, officers, directors, employees, agents and representatives, and each of their respective successors and assigns (collectively, the “Parent Related Parties”) against Purchaser, the Purchaser Sponsors, the Debt Financing Sources and any of their respective former, current and future direct or indirect Affiliates, Representatives, shareholders, members, managers, general or limited partners, management companies, investment vehicles, officers, directors, employees, agents and representatives, and each of their respective successors and assigns (collectively, the “Purchaser Related Parties”) for any and all breaches (whether knowing, willful, intentional, unintentional or otherwise), Losses, damages or Liabilities, including, but not limited to, special, indirect or punitive damages, suffered or incurred by any Parent Related Party or any other Person in connection with this Agreement, the Debt Commitment Letter, the transactions contemplated hereby or thereby (and the abandonment or termination thereof) or any matter forming the basis for such termination, and no Parent Related Party, nor any other Person, shall be entitled to assert, bring or maintain, and Parent on behalf of itself and each of the other Parent Related Parties hereby waives any right to assert, bring or maintain, any Action against Purchaser or any other Purchaser Related Party arising out of or in connection with this Agreement, the Debt Commitment Letter, the transactions contemplated hereby or thereby (and the abandonment or termination thereof) or any matter forming the basis for such termination, whether by or through (a) attempted piercing of the corporate veil, (b) a claim by or on behalf of Purchaser or one of its Affiliates against another Purchaser Related Party or (c) any legal or equitable proceeding whether at law, in equity, in contract, in tort or otherwise; provided that nothing in this Section 10.3(d) shall limit the right of Parent to, subject to Section 10.3(e), seek an injunction, specific performance or other equitable relief pursuant to Section 11.11 prior to termination of this Agreement. For the avoidance of doubt, under no circumstances will Parent or any other Parent Related Party (or the Parent Related Parties in the aggregate) be entitled to, and Parent shall not, and shall cause the other Parent Related Parties not to, accept aggregate monetary damages or other monetary remedies in excess of the amount of the Termination Fee for any and all breaches (whether knowing, willful, intentional, unintentional or otherwise), Losses, damages or Liabilities, including special, indirect or punitive damages, suffered or incurred by any Parent Related Party or any other Person in connection with this Agreement, the Debt Commitment Letter, the transactions contemplated hereby or thereby (and the abandonment or termination thereof) or any matter forming the basis for such termination, and including in connection with the Reimbursement Obligations set forth in Section 6.16(d).

(e)    For the avoidance of doubt, while Parent may pursue both a grant of specific performance pursuant to Section 11.11, on the one hand, and the payment of the Termination Fee pursuant to Section 10.3(b), on the other hand, under no circumstances may Parent or any other Parent Related Party be permitted or entitled to receive both a grant of specific performance and any money damages, including all or any portion of the Termination Fee. In addition,

-98-

notwithstanding anything in this Agreement to the contrary, Parent, on behalf of itself and the other Parent Related Parties, hereby waives any claims against the Debt Financing Sources and hereby agrees that in no event shall the Debt Financing Sources have any liability or obligation to Parent or any other Parent Related Party relating to or arising out of this Agreement, the Debt Financing, the Debt Commitment Letter or the transactions contemplated hereby or thereby; provided that, notwithstanding the foregoing, nothing in this Section 10.3(e) shall in any way limit or modify the rights and obligations of Purchaser under the Debt Commitment Letter.

Section 10.4    Extension; Waiver. At any time prior to the Closing, either Parent, on the one hand, or Purchaser, on the other hand, may (a) extend the time for performance of any of the obligations or other acts of the other, (b) waive any inaccuracies in the representations and warranties of the other contained in this Agreement or in any document delivered pursuant to this Agreement or (c) waive compliance with any of the agreements or conditions of the other contained in this Agreement. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the party granting such extension or waiver.

Section 11.8    Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties to this Agreement and their respective successors and assigns; provided that no party to this Agreement may directly or indirectly assign any or all of its rights or delegate any or all of its obligations under this Agreement without the express prior written consent of each other party to this Agreement, except that (a) Parent may transfer or assign, in whole or from time to time in part, its rights under this Agreement to any Affiliate of Parent, but any such transfer or assignment will not relieve Parent of any of its obligations hereunder and (b) Purchaser may transfer or assign, its rights, interests or obligations under this Agreement, in whole or from time to time in part, to one or more of its Affiliates (including, following the Closing, the Transferred Entities) or to any of its Debt Financing Sources for purposes of creating a security interest herein or otherwise assigning as collateral in respect of the Debt Financing and any refinancings, extensions, refundings or renewals thereof, but any such transfer or assignment will not relieve Purchaser of any of its obligations hereunder.

Section 11.9    Amendments and Waivers. This Agreement may not be modified or amended except by an instrument or instruments in writing signed by the party against whom enforcement of any such modification or amendment is sought; provided however that, Section 10.3(d), Section 10.3(e), Section 11.5, Section 11.8(b) (with respect to the Debt Financing Sources), the first sentence of this Section 11.9, Section 11.12 and the definitions of “Debt Commitment Letter,” “Debt Financing,” “Debt Financing Sources,” “Marketing Period” and “Purchaser Related Parties” (and any other provisions of this Agreement to the extent a modification thereof would adversely modify the substance of any of the foregoing as it affects

-103-

the Debt Financing Sources) may not be amended or modified in a manner that is materially adverse to any Debt Financing Source without the written consent of the related Debt Financing Sources party to the Debt Commitment Letter. Any party to this Agreement may, only by an instrument in writing, waive compliance by the other party to this Agreement with any term or provision of this Agreement on the part of such other party to this Agreement to be performed or complied with. The waiver by any party to this Agreement of a breach of any term or provision of this Agreement shall not be construed as a waiver of any subsequent breach. No failure or delay by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

Section 11.10    Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

Section 11.11    Specific Performance.

(a)    The parties hereto agree that irreparable damage, for which monetary damages (even if available) would not be an adequate remedy, would occur in the event that the parties hereto do not perform any provision of this Agreement in accordance with its specified terms or otherwise breach such provisions. Accordingly, subject to Section 11.11(b), the parties hereto acknowledge and agree that the parties hereto shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches or threatened breaches of this Agreement and to enforce specifically the terms and provisions hereof, in addition to any other remedy to which they are entitled in Law or in equity. Each of the parties hereto agrees that it will not oppose, and irrevocably waives its right to object to, the granting of an injunction, specific performance or other equitable relief on the basis that any other party has an adequate remedy at Law or that any award of specific performance is not an appropriate remedy for any reason at Law or in equity. Any party hereto seeking an injunction or injunctions to prevent breaches or threatened breaches of this Agreement or to enforce specifically the terms and provisions of this Agreement shall not be required to provide any bond or other security in connection with such order or injunction. Without limiting the generality of the foregoing, the parties agree that Parent shall be entitled to specific performance against Purchaser of Purchaser’s obligations under Section 6.16.

(b)    Notwithstanding anything to the contrary in this Agreement or otherwise, it is acknowledged and agreed that the right of Parent to specific performance in connection with enforcing the obligations of Purchaser hereunder to cause the Equity Financing to be funded and to consummate the Closing shall be subject to the requirements that: (i) the Marketing Period has ended and all of the conditions in Section 9.1 and Section 9.2 (other than those conditions that by their nature are to be satisfied by the taking of actions or delivery of documents, or waived, at the

-104-

Closing, each of which is then capable of being satisfied at the Closing) have been satisfied and remain satisfied or have been irrevocably waived by Purchaser (to the extent such waiver is permitted under applicable Law), (ii) the Debt Financing (or any Alternative Financing in accordance with Section 6.16) has been funded or is reasonably capable of being, or is available to be funded, in full at the Closing if the Equity Financing is funded at the Closing (or, if the Debt Financing (or any such Alternative Financing) has been funded into escrow, such funds have been or would be released from escrow), (iii) Parent has irrevocably notified Purchaser in writing that all of the conditions set forth in Section 9.1 and Section 9.3 (other than those conditions that by their nature are to be satisfied by the taking of actions or delivery of documents, or waived, at the Closing, each of which is then capable of being satisfied at the Closing) have been satisfied and remain satisfied and Parent has confirmed by irrevocable written notice delivered to Purchaser that Parent is willing to waive any unsatisfied conditions in Section 9.1 and Section 9.3 (if applicable, and to the extent such waiver is permitted under applicable Law) and is otherwise ready, willing and able to consummate the Closing and that if specific performance is granted and the Equity Financing and Debt Financing (or any Alternative Financing in accordance with Section 6.16) were funded, and Purchaser otherwise complies with its obligations hereunder, then the Closing will occur, and (iv) Purchaser has failed to consummate the Closing on the date the Closing is required to occur under Section 2.3(a).

Section 11.13    No Admission. Nothing herein shall be deemed an admission by Purchaser, Parent or any of their respective Affiliates, in any Action or Action by or on behalf of a third party, that Purchaser, Parent or any of their respective Affiliates, or that such third party or any of its Affiliates, is or is not in breach or violation of, or in default in, the performance or observance of any term or provisions of any Contract.

Section 11.14    No Survival of Representations, Warranties, Covenants and Agreements.

(a)    The representations, warranties, covenants and agreements in this Agreement shall terminate at the Closing or upon the termination of this Agreement pursuant to Article X, except that: (i) the covenants and agreements set forth in Section 6.4, Section 6.5, Section 6.6, Section 6.7, Section 6.8, Section 6.10(b), Section 6.17, Section 6.19, Section 6.20, Section 6.22, Section 7.1, Section 7.6(a), Section 7.7, Section 8.1(a) and Section 8.6, in each case, solely to the extent such covenants and agreements contemplate performance, in whole or in part, prior to the Closing shall survive the Closing for a period of three months from the Closing Date; and (ii) the covenants and agreements in this Agreement that explicitly contemplate performance, in whole or in part, at or after the Closing shall survive the Closing until fully performed in accordance with their respective terms. The parties hereto acknowledge and agree that, other than in connection with any Fraud, from and after the Closing they shall not be permitted to make, and no party shall have any liability or obligation with respect to, any claims for any breach of any representation or warranty set forth herein or any covenant or agreement herein that is to have been performed by another party on or prior to the Closing. In furtherance of the foregoing, other than in connection with any Fraud, from and after the Closing, each party hereto hereby waives (on behalf of itself, each of its Affiliates and each of its Representatives), to the fullest extent permitted under Law, any and all rights, claims and causes of action (including any statutory rights to contribution or indemnification) to the extent arising under or based upon this Agreement or any

-106-

document or certificate delivered in connection herewith (including for any breach of any representation or warranty or covenant or obligation to have been performed prior to the Closing set forth herein or otherwise relating to any of Purchaser, the Sellers or the Transferred Entities or the subject matter of this Agreement that such party may have against the other parties or any of their Affiliates or any of their respective Representatives arising under or based upon any theory whatsoever, under any Law, contract, tort or otherwise).

(b)    Purchaser hereby acknowledges and agrees that, except as expressly provided in Section 2.7, the foregoing Section 11.14(a) or in connection with any Fraud or as provided in any Ancillary Agreement, from and after Closing none of Parent, its Representatives or any of their respective Affiliates, officers, managers, employees or agents, shall have any liability, responsibility or obligation arising under this Agreement or any exhibit or Schedule hereto, or any certificate or other document entered into, made, delivered, or made available in connection herewith, or as a result of any of the transactions contemplated hereby, such provisions and other documents being the sole and exclusive remedy (as between the Purchaser and its Affiliates, on the one hand, and the Parent and its Affiliates, on the other hand) for all claims, disputes and losses arising hereunder or thereunder or in connection herewith or therewith, whether purporting to sound in contract or tort, or at Law or in equity, or otherwise.

Section 11.15    Privilege. Purchaser hereby agrees, on its own behalf and on behalf of its Affiliates (including the Transferred Entities after the Closing), that, following the Closing, Ropes & Gray LLP and Babst, Calland, Clements and Zomnir, P.C. (“Parent Group’s Counsel”) may serve as counsel to the Parent Group and their Affiliates in connection with any matters related to this Agreement or the transactions contemplated hereby, including any litigation, claim or obligation arising out of or relating to this Agreement or the Ancillary Agreements, the negotiation, performance or subject matter hereof or thereof, or the Sale, notwithstanding any representation by Parent Group’s Counsel prior to the Closing Date of the Transferred Entities. Purchaser hereby agrees, on its own behalf and on behalf of its Affiliates (including the Transferred Entities after the Closing), (i) to waive any claim they have or may have that Parent Group’s Counsel has a conflict of interest or is otherwise prohibited from engaging in such representation and (ii) that, in the event that a dispute arises after the Closing between Purchaser or any of its Affiliates (including any Transferred Entity), on the one hand, and the Parent Group or any of their Affiliates, on the other hand, Parent Group’s Counsel may represent the Parent Group and/or any of its Affiliates in such dispute even though the interests of such Person(s) may be directly adverse to Purchaser or any of its Affiliates (including any Transferred Entity) and even though Parent Group’s Counsel may have represented any Transferred Entity in a matter substantially related to such dispute. Purchaser, on behalf of itself and its Affiliates (including the Transferred Entities after the Closing) also further agree that, as to all communications to or from Parent Group’s Counsel, on the one hand, and any or all of the Transferred Entities, the Parent Group or their Affiliates and their respective Representatives, on the other hand, that relate in any way to this Agreement or any Ancillary Agreement, the negotiation, performance or subject matter hereof or thereof, or the transactions contemplated hereby, the attorney-client privilege and the expectation of client confidence belongs and will belong solely to the Parent Group and will not pass to or be claimed by Purchaser or its Affiliates (including any Transferred Entity after the Closing). Without limitation of the foregoing, none of Purchaser or any of its Affiliates (including any Transferred Entity after the Closing) may use or rely upon any communications described in the immediately preceding sentence in any dispute against or involving the Parent Group. Notwithstanding the

-107-

foregoing, in the event that a dispute arises after the Closing between Purchaser or any of its Affiliates (including any Transferred Entity), on the one hand, and a third party other than (and not an Affiliate of) a party to this Agreement, on the other hand, a Transferred Entity may assert the attorney-client privilege to prevent disclosure of confidential communications by Parent Group’s Counsel to such third party; provided, however, that such Transferred Entity may not waive such privilege without the prior written consent of Parent. Purchaser acknowledges that it has consulted with independent counsel of its own choosing with respect to the meaning and effect of this Section 11.15. Parent Group’s Counsel is an express intended third party beneficiary of this Agreement for purposes of this Section 11.15, and may enforce the same. This Section 11.15 will survive the Closing and will remain in effect indefinitely.

Section 11.16    Counterparts. This Agreement may be executed in one or more counterparts, and by the different parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile or other electronic method shall be as effective as delivery of a manually executed counterpart of this Agreement.

Section 11.17    Sale or Transfer of Catalyst Business. If Parent at any time determines to sell or otherwise transfer to a third party (including by way of stock sale, asset sale, merger or otherwise) (a) all or substantially all of the Catalyst Business (it being understood that “substantially all” for this purpose shall mean more than either of the following on their own (1) the portions of the Catalyst Business described in clauses (a) and (b) of the definition of Catalyst Business, or (2) the portion of the Catalyst Business described in clause (c) of the definition of Catalyst Business), then in connection with such sale or transfer, Parent shall, and shall cause the other members of the Parent Group to, require that the purchaser of the Catalyst Business assume all of the Parent Group’s obligations and Liabilities under Section 6.1(c), Section 6.1(d), Section 6.1(g), Section 6.1(h), Section 6.2, Section 6.5, Section 6.6, Section 6.9, Section 6.10, Section 6.11, Section 6.12, Section 6.13, Section 6.14(d), Section 6.15, Section 6.18, Section 6.22, Article VII, Article VIII and this Section 11.17 and all of the Parent Group’s obligations under all Ancillary Agreements, other than the Transition Services Agreement and in each case only to the extent that such obligations or Liabilities have not yet been fully performed or satisfied in accordance with their respective terms at the time of such sale or transfer (collectively, the “Transferred Catalyst Obligations”), and Purchaser shall extend the benefit of Section 6.14(e) to any such purchaser, (b) the portions of the Catalyst Business described in clauses (a) and (b) of the definition of Catalyst Business, then in connection with such sale or transfer, Parent shall, and shall cause the other members of the Parent Group to, require that the purchaser of such portions of the Catalyst Business assumes the applicable portion of the Transferred Catalyst Obligations (and Purchaser shall extend the benefit of Section 6.14(e) to any such purchaser), or (c) the portion of the Catalyst Business described in clause (c) of the definition of Catalyst Business, then in connection with such sale or transfer, Parent shall, and shall cause the other members of the Parent Group to, require that the purchaser of such portion of the Catalyst Business assumes the applicable portion of the Transferred Catalyst Obligations (and Purchaser shall extend the benefit of Section 6.14(e) to any such purchaser). In connection with the consummation of any such sale or transfer, Parent shall ensure that Purchaser and its Affiliates shall, to the extent not directly a party thereto, be third party beneficiaries of the provisions pursuant to which the applicable purchaser assumes the obligations and Liabilities contemplated by the foregoing sentence so as to ensure its ability to enforce the terms hereof.

All Actions, obligations, Losses, damages, claims or causes of action (whether in contract, in tort, in law or in equity, or granted by statute whether by or through attempted piercing of the corporate, limited partnership or limited liability company veil or otherwise) that may be based upon, arise under, out or by reason of, be connected with, or relate in any manner to (a) this Agreement or any Ancillary Agreement or any of the other agreements or documents contemplated hereby or thereby, (b) the negotiation, execution or performance of this Agreement or any Ancillary Agreement or any of the documents contemplated hereby or thereby (including any representation or warranty made in connection with, or as an inducement to, this Agreement or any of the other agreements or documents contemplated hereby), (c) any breach or violation of this Agreement or any Ancillary Agreement (including the failure of any representation and warranty to be true or accurate) or any of the other agreements or documents contemplated hereby or thereby, and (d) any failure of the transactions contemplated by this Agreement or any Ancillary Agreement or the other agreements, transactions or documents contemplated hereby or thereby to be consummated, in each case, may be made only against (and are those solely of) the Persons that are expressly named as parties to this Agreement, the Equity Commitment Letter, the Limited Guarantee, the Confidentiality Agreement and any other Ancillary Agreements, and then only to the extent of the specific obligations of such Persons set forth in this Agreement, the Equity Commitment Letter, the Limited Guarantee, the Confidentiality Agreement or such other Ancillary Agreement, as applicable.
