Seller hereby represents and warrants to Purchaser that, except as set forth in the Disclosure Schedules dated as of the date hereof and delivered by Seller to Purchaser (the “Seller Disclosure Schedules”):

Section 5.1. Organization and Good Standing. Each of Seller and Eastman EPC are duly organized, validly existing and in good standing under the laws of the jurisdiction in which it was incorporated and has all requisite power and authority to own, lease and operate its properties and assets and to carry on, in all material respects, the Business. Seller and Eastman EPC are each duly qualified, authorized or licensed to conduct business under the laws of each jurisdiction in which the conduct of the Business or the ownership or lease of the assets owned or leased by it in respect of the Business requires such qualification, authorization or license, except where the failure to be so qualified, authorized or licensed would not reasonably be expected to have a Material Adverse Effect on the Business.

Section 5.2. Authorization of Agreement. Each of Seller and Eastman EPC has all requisite power and authority to execute and deliver this Agreement and each other agreement, document, instrument or certificate contemplated hereby to be executed and delivered by it in connection with the consummation of the transactions contemplated hereby (all such other agreements, documents, instruments and certificates required to be executed by Seller or Eastman EPC being hereinafter referred to, collectively, as the “Seller Documents”) and to perform its obligations contemplated hereby and thereby. The execution, delivery and

performance by Seller of this Agreement and each Seller Document to which it is a party, and the execution, delivery and performance by Eastman EPC of each of the Seller Documents to which it is a party, have been duly authorized by all necessary corporate action on the part of Seller and Eastman EPC. This Agreement has been duly executed and delivered by Seller and (assuming the due authorization, execution and delivery hereof by Purchaser) constitutes a legal, valid and binding obligation of Seller, enforceable against Seller in accordance with its terms, except that (i) the enforceability hereof may be limited by bankruptcy, insolvency, moratorium or other similar laws affecting the enforcement of creditors’ rights generally, and (ii) the availability of equitable remedies may be limited by equitable principles of general applicability. Each of the Seller Documents will be, on or prior to the Closing Date, duly executed and delivered by, as applicable, Seller and/or Eastman EPC and (assuming the due authorization, execution and delivery thereof by Purchaser) each of the Seller Documents when so executed and delivered will constitute a legal, valid and binding obligation of, as applicable, Seller and/or Eastman EPC, enforceable against them in accordance with their respective terms, except that (A) the enforceability thereof may be limited by bankruptcy, insolvency, moratorium or other similar laws affecting the enforcement of creditors’ rights generally, and (B) the availability of equitable remedies may be limited by equitable principles of general applicability.

No consent, waiver, approval, Permit or authorization of, or declaration or filing with, or notification to, any Person or Governmental Body is required on the part of Seller or Eastman EPC in connection with the execution and delivery of this Agreement or the Seller Documents, the consummation of the transactions contemplated hereby and thereby or the compliance by Seller and Eastman EPC with any of the provisions hereof or thereof, except (y) for such consents, waivers, approvals, Permits or authorizations of, or declarations or filings with, or notifications to, any Person or Governmental Body, the failure to receive or make is not reasonably likely to have a Material Adverse Effect on the Business, and (z) for compliance with the applicable requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the rules and regulations promulgated thereunder (the “HSR Act”).

Section 5.4. Capitalization; Equity Interests. Schedule 5.4 of the Seller Disclosure Schedules sets forth the authorized and outstanding capital stock of Eastman EPC. All of the issued and outstanding shares of the capital stock of Eastman EPC have been duly authorized

and validly issued and are fully paid and nonassessable and are owned of record by Seller. Seller is the sole record and beneficial holder of the Purchased Shares. Seller owns the Purchased Shares free and clear of all Liens and Restrictions and such shares represent all of the issued and outstanding capital stock of Eastman EPC. There are no outstanding (a) securities of Eastman EPC convertible into or exchangeable for shares of capital stock or voting securities of Eastman EPC, or (b) options or other rights in favor of third parties to acquire from Eastman EPC, and no obligation of Eastman EPC to issue, any capital stock, voting securities, or securities convertible into or exchangeable for capital stock or voting securities.

The Full Year Financial Statements and the Interim Financial Statements have not been prepared in accordance with GAAP standards for presentation on a standalone basis, and both include certain items that are eliminated in consolidation as described therein and exclude certain items that may customarily be included in consolidations as described therein. The Full Year Financial Statements and the Interim Financial Statements have been derived from, and prepared in accordance with, the books and records of Seller and its Affiliates.

each promptly provide counsel for the other party with copies of all filings made by such party, and all correspondence between such party (and its advisors) and any Governmental Body and any other information supplied by such party and such party’s Affiliates to a Governmental Body in connection herewith and the transactions contemplated hereby; provided, however, that Purchaser and Seller may, as each deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other as for “outside counsel only,” and materials may be redacted (i) to remove references concerning the valuation of the Business and (ii) as necessary to comply with contractual arrangements. Materials designated as for “outside counsel only” and the information contained therein shall be given only to the outside legal counsel of the recipient and will not be disclosed by such outside counsel to employees, officers or directors of the recipient unless express permission is obtained in advance from the source of the materials (Purchaser or Seller, as the case may be) or its legal counsel.

The cost and expense of preparing such additional financial statements (including the costs of Seller’s auditors) shall be borne solely by Purchaser.

COVENANTS OF PURCHASER

From and after the date hereof and until the Closing (except with respect to Section 8.1, Section 8.4 and Section 8.6, which shall survive the Closing in accordance with their terms), Purchaser hereby covenants and agrees that:

Section 8.1. Confidentiality. As of the Closing Date, the Confidentiality Agreement shall terminate and cease to be of effect to the extent information and materials relate to the Business. From and after the Closing, none of Purchaser or any of its Affiliates shall use or

disclose any non-public or proprietary information of Seller and its Affiliates that do not relate to the Business except as permitted under the Technology Transfer Agreement (“Seller Proprietary Information”). This Section 8.1 shall not apply to any Seller Proprietary Information which (a) through no fault of Purchaser or any of its Affiliates is or becomes generally known in the relevant industry, (b) is received after the Closing from a third party free of any limitations on its use or disclosure and not, to Purchaser’s knowledge, through violation of any confidentiality agreement or (c) is independently developed after the Closing without any reference to any Seller Proprietary Information. Purchaser may make any legally required disclosure of the Seller Proprietary Information, but Purchaser shall notify Seller before making any such legally required disclosure and use its commercially reasonable efforts to limit the amount of Seller Proprietary Information so disclosed to protect its confidentiality to the extent possible.

Section 8.2. Public Statements. Before Purchaser shall issue any press release or otherwise make any public statement concerning this Agreement or the transactions contemplated hereby, Purchaser shall so advise and cooperate with Seller and shall not release such information without Seller’s consent (which consent shall not be unreasonably withheld, conditioned or delayed), unless (a) such information is otherwise publicly available other than as a result of a disclosure by Purchaser made in breach of this Section 8.2 or (b) the release thereof is, in the reasonable judgment of Purchaser, required by any Law (including any rule of any securities exchange on which Purchaser’s securities are traded) or Order to which Purchaser is bound or subject; provided, however, in the case of this clause (b), that Purchaser shall take all reasonable endeavors to notify Seller prior to making any such disclosure and shall restrict such disclosure to the minimum required by Law (in the reasonable judgment of Purchaser).

Section 8.3. Consents and Conditions.

(a) Purchaser shall use all commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with Seller in doing, all things necessary, proper or advisable to consummate and make effective the transactions contemplated hereby as promptly as practicable, including, but not limited to: (i) obtaining all necessary consents, approvals or waivers from, and giving any necessary notifications to, third parties; (ii) making all registrations and filings as promptly as practicable with, and obtaining all necessary actions or non-actions, waivers, consents and approvals from, all Governmental Bodies (including those in connection with the HSR Act as further provided below and any other applicable Law) and using all commercially reasonable efforts to obtain an approval or waiver from, or to avoid an action or proceeding by, a Governmental Body; (iii) responding to any information requests from Governmental Bodies as soon as reasonably practicable; and (iv) defending any Proceedings challenging this Agreement or the consummation of the transactions contemplated hereby, including seeking to have any stay or temporary restraining order or preliminary or permanent injunction entered by any Governmental Body vacated or reversed.

(b) Purchaser shall keep Seller reasonably apprised of the status of matters relating to the completion of the transactions contemplated hereby, including promptly furnishing Seller with copies of notices or other communications received by Purchaser or by any of its Affiliates from any third party and/or any Governmental Body with respect to the transactions contemplated hereby. Purchaser and Seller shall each promptly furnish to the other such

necessary information and reasonable assistance as the other party may request in connection with the foregoing and shall each promptly provide counsel for the other party with copies of all filings made by such party, and all correspondence between such party (and its advisors) and any Governmental Body and any other information supplied by such party and such party’s Affiliates to a Governmental Body in connection herewith and the transactions contemplated hereby; provided, however, that Purchaser and Seller may, as each deems advisable and necessary, reasonably designate any competitively sensitive material provided to the other as for “outside counsel only,” and materials may be redacted (i) to remove references concerning the valuation of the Business and (ii) as necessary to comply with contractual arrangements. Materials designated as for “outside counsel only” and the information contained therein shall be given only to the outside legal counsel of the recipient and will not be disclosed by such outside counsel to employees, officers or directors of the recipient unless express permission is obtained in advance from the source of the materials (Purchaser or Seller, as the case may be) or its legal counsel. Each party shall, subject to applicable Law, permit counsel for the other party reasonable opportunity to review in advance, and consider in good faith, the views of the other party in connection with, any proposed written communication to any Governmental Body. Purchaser and Seller agree not to participate, or to permit their affiliates to participate, in any substantive meeting or discussion, either in person or by telephone, with any Governmental Body in connection herewith and the transactions contemplated hereby unless it consults with the other party in advance and, to the extent not prohibited by such Governmental Body, gives the other party the opportunity to attend and participate; provided, however, that Purchaser shall not be deemed to have breached this covenant if (x) Purchaser uses efforts reasonable under the circumstances to contact Seller or its representatives, but is nonetheless unable to reach any such designated representatives prior to the time at which such Governmental Body proposes to conduct such meeting or discussion, or (y) any such designated representatives are unable to participate in such meeting or discussion at the proposed time.

(c) In furtherance and not in limitation of the covenants of the Purchaser contained in Section 8.3(a) and Section 8.3(b), Purchaser shall use all commercially reasonable efforts to cause the expiration or termination of the applicable waiting periods under the HSR Act and not to extend any waiting period under the HSR Act (except with the prior written consent of Seller, which shall not be unreasonably withheld or delayed) or enter into any agreement with the Federal Trade Commission or the Department of Justice not to consummate the transactions contemplated hereby. Purchaser shall offer to take (and if such offer is accepted, commit to take) all steps that it is capable of taking to avoid or eliminate impediments under any antitrust, competition or trade regulation Law that may be asserted or threatened by any Governmental Body with respect to the transactions contemplated hereby (or by any private party) so as to enable the Effective Time to occur no later than the expiration of the time period set forth in Section 14.1(c) (the “Termination Date”), and shall defend through litigation on the merits any claim asserted in any court by any party, including appeals. In addition to and without limiting the foregoing, Purchaser shall cooperate in all respects with Seller and use all its best efforts to propose, negotiate, offer to commit and effect (and if such offer is accepted, commit to and effect), by consent decree, hold separate order, or otherwise, the sale, divestiture or disposition of such assets or businesses of Purchaser or its Affiliates, or otherwise offer to take or offer to commit to take any action which it is capable of taking and if the offer is accepted, take or commit to take such action, that limits its freedom of action with respect to, or its ability to retain, any of Business as a whole, in order to avoid the filing of any suit or proceeding or the

entry of, or to effect the dissolution of, any Order, which would otherwise have the effect of preventing or delaying the Effective Time beyond the Termination Date, or which may be necessary to allow the Effective Time to occur prior to the Termination Date. Notwithstanding the foregoing or any other provision of this Agreement, nothing in this Section 8.3(c) shall limit a party’s right to terminate this Agreement pursuant to ARTICLE XIV so long as such party has complied with its obligations under this Section 8.3(c) immediately prior to any termination.

Section 8.4. Seller’s Access to Documents. Purchaser shall, and shall cause its Affiliates to, afford to Seller’s representatives, upon reasonable notice and without undue interruption to Purchaser’s business, access during normal business hours to the books and records of the Business pertaining to the operations of the Business prior to the Closing Date for a period of five (5) years (or such longer period as may necessary to enable Seller to comply with provisions of applicable Law) following the Closing Date for the purposes of (a) allowing Seller to comply with SEC reporting obligations, and (b) other reasonable business purposes; provided, however, that nothing in this Section 8.4 shall affect either party’s discovery rights in the event of a dispute between them. Purchaser agrees to hold all of the books and records of the Business existing on the Closing Date in accordance with Purchaser’s standard record retention policies provided that Purchaser shall not destroy, alter or dispose of any of such books and records for a period of ten (10) years from the Closing Date or such longer time as may be required by Law without first offering in writing at least sixty (60) calendar days prior to such destruction or disposition to surrender them to Seller.

Section 8.5. Further Actions. Purchaser shall use all commercially reasonable efforts to satisfy or cause to be satisfied as promptly as practicable its obligations hereunder and the conditions precedent to Closing.

Section 8.6. Use of Seller’s Names and Marks. Purchaser agrees that: (a) effective as of the Closing Date, Purchaser shall change the name of Eastman Ethylene Polymers Company, to a name that is not confusingly similar to the foregoing name, and specifically removing the name “Eastman” from the entity’s name; (b) as of the Closing date, Purchaser agrees that it will not further use, distribute or display, and/or will cease to further use, distribute or display, any article or instrument of any kind, including signs, invoices, labels, letterhead, or business cards, that reflects or includes any logo, trademark, trade name, trade dress, or those confusingly similar thereto to the extent depicting or suggesting an Erlenmeyer flask, or similar designation of Seller that was not specifically assigned to Purchaser under the Technology Transfer Agreement or the Trademark Assignment Agreement; (c) Purchaser agrees, within a reasonable time following the Closing date (not to exceed sixty (60) days and not to exceed three (3) months in the case of exhausting preprinted materials on finished products), to destroy any and all such articles or instruments in its possession, and to modify any web site or web page regarding the Business to remove any such logo, trademark, trade name, trade dress, font type or similar designation of Seller that was not specifically assigned to Purchaser; (d) and as soon as reasonably practicable after the Closing, Purchaser shall mark products and other property acquired hereunder, both internally and externally, with Purchaser’s name and mark; and (e) it shall not advertise or hold itself out as Seller or an Affiliate thereof.

Section 8.7. Solicitation of Customers by Purchaser Prior to Closing. Prior to the Closing Date, Purchaser will not, and will not permit any of its Affiliates, to utilize confidential

information of Seller or its Affiliates or the transactions contemplated hereby in connection with the solicitation of customers of the Business to discontinue or limit their relationships with Seller or to conduct any marketing or other customer solicitation activities outside of the ordinary course of business of Purchaser, consistent with past practice, which are targeted to induce any such customers to discontinue or limit any such relationships, it being understood and agreed that the foregoing is not intended to prohibit general advertising or solicitations directed to the public generally or other similar activities conducted in the ordinary course of business of Purchaser consistent with past practice and without making reference to this Agreement or the transactions contemplated hereby.

(b) Except for actions based on fraud, fraudulent inducement or fraudulent misrepresentation, the parties hereto acknowledge and agree that in the event the Closing occurs, the indemnification provided for in this ARTICLE XII shall be the sole and exclusive remedy for monetary damages of the parties for any breach of this Agreement or the representations, warranties, covenants or agreements herein by either party hereto.

(c) In calculating any amount of Losses recoverable pursuant to Section 12.2 or Section 12.3, the amount of such Losses shall be (i) reduced by (A) any insurance proceeds actually received relating to such Loss, net of any related deductible and any expenses to obtain such proceeds, (B) any recoveries from third parties pursuant to indemnification (or otherwise) with respect thereto, net of any expenses incurred by the Indemnified Party in obtaining such third party payment and (C) the amount of any net Tax benefit resulting from the incurrence or

(b) Except with respect to those matters addressed in Section 12.3(b) (which shall be exclusively governed thereby), Purchaser hereby agrees to indemnify and hold the Seller Indemnified Group harmless from and against any and all Losses actually incurred by any of them to the extent arising out of or resulting from:

(i) any breach as of the Closing Date of a representation or warranty made by Purchaser herein;

(ii) any breach of any covenant or agreement of Purchaser herein;

(iii) any Purchaser’s Pipeline Indemnities; and

(iv) the ownership and operation of the Business from and after the Closing Date.

Section 12.3. Allocation of Environmental Liabilities; Environmental Indemnification.

(a) Seller Indemnification. Subject to the limitations set forth in Section 12.2(a), Seller shall indemnify and hold the Purchaser Indemnified Group harmless from any Losses asserted against or incurred by any of these under Environmental Laws to the extent arising out of or resulting from (i) any breach of a representation or warranty of Seller made in Section 5.17 of this Agreement, provided, however, that in the event of a breach of the warranty in Section 5.17(a), Seller shall only be liable to the Purchaser Indemnified Group for Penalties assessed against Purchaser as a result or as a consequence of that breach, (ii) any off-site liability arising under CERCLA (or state law based on CERCLA) as the result of the arrangement for disposal of Hazardous Substances by the Business prior to the Closing Date, (iii) subject to the requirements of Sections 12.3(c) and (e) hereof, any Order issued by an Environmental Authority regarding noncompliance with Environmental Laws by the Business or by the Seller prior to the Closing Date, provided, however, that Seller’s liability under this clause (iii) shall be limited to paying (x) all Penalties imposed or assessed, and (y) 50% of any capital costs required to comply with such Order, and (iv) subject to the requirements of Sections 12.3(d), (e), (f) and (g) hereof, any Release of Hazardous Substances by Seller (A) originating prior to the Closing Date on, in or from the Eastman EPC Leased Real Property or (B) migrating onto or under or from the Eastman EPC Leased Real Property as a result of any Releases by Seller or any of its Affiliates prior to or after the Closing Date (hereinafter collectively referred to as, “Seller’s Release”), including any migration that continues to occur after the Closing.

(b) Purchaser Indemnification. Purchaser shall indemnify and hold the Seller Indemnified Group harmless from any Losses asserted against or incurred by any of these under Environmental Laws to the extent arising out of or resulting from (i) any noncompliance with Environmental Laws by the Business or by Purchaser in connection with the operation of the Business after the Closing Date, (ii) any off-site liability arising under CERCLA (or state law based on CERCLA) as the result of the arrangement for disposal of Hazardous Substances by the Business after the Closing Date, and (iii) subject to the requirements of Sections 12.3(d), (e) and (f) hereof, any Release of Hazardous Substances after the Closing Date by the Business or the Purchaser, or their agents, contractors, employees or invitees, at the Eastman EPC Leased Real Property or at Seller’s Longview, Texas facility (including, but not limited to, any Release by the Business or the Purchaser that aggravates a Seller’s Release) (“Purchaser’s Release”).

(c) Reservoir Projects. Notwithstanding anything to the contrary in this Section 12.3, responsibility for Losses arising directly out of the use or operation by the Business of the Cooling Water Reservoirs 1 and 2 before or after the Closing Date shall be allocated and managed in accordance with the provisions of Section 11(i) of the Ground Lease as set forth in Exhibit D hereto.

(d) Cleanup of Seller’s Release; Cleanup of Purchaser’s Release.

(i) Where required by Environmental Law or where subject to indemnification by Seller hereunder, Seller shall design and conduct the Response to a Seller’s Release. Seller’s Response shall comply with the applicable standards of Environmental Law and shall conform with prudent and generally accepted industry practices to address a potential risk to human health or the Environment. Seller’s Response may incorporate risk-based corrective action, where applicable. Prior to the implementation of any material phase of the Response that will occur on or directly impact the Eastman EPC Leased Real Property, Seller shall provide Purchaser with written proposed plans, workplans, sampling location maps and schedules for Purchaser’s review and approval, such approval not to be unreasonably withheld. Seller shall design and conduct any Response to a Seller’s Release (including the continuation of any Response initiated before Closing) in a manner that minimizes, to the maximum extent feasible, any material disruption of or interference with the operations of the Business or the Eastman EPC Leased Real Property. Without in any way limiting the scope of the preceding sentence, Seller covenants that it will continue to timely and fully perform and be financially responsible for the investigation and remediation of the soil and groundwater contamination that is currently being performed by Seller pursuant to the requirements of Compliance Plan No. 50043, which is incorporated into Seller’s Hazardous Waste Facility Permit No. 50043 as issued

by the TCEQ. Seller also covenants that it will timely and fully perform and be financially responsible for any expanded or modified investigation or remediation that may be required by the TCEQ or the U.S. Environmental Protection Agency to the extent that such modification or expansion is designed to address contamination existing at Seller’s Longview, Texas facility as of the Closing Date.

(ii) Where required by Environmental Law or where subject to indemnification by Purchaser hereunder, Purchaser shall design and conduct the Response to a Purchaser’s Release. Purchaser’s Response shall comply with the applicable standards of Environmental Law and shall conform with prudent and generally accepted industry practices to address a potential risk to human health or the Environment. Purchaser’s Response may incorporate risk-based corrective action, where applicable. Prior to the implementation of any material phase of the Response, Purchaser shall provide Seller with written proposed plans, workplans, sampling location maps and schedules for Seller’s review and approval, such approval not to be unreasonably withheld. Purchaser shall design and conduct any Response to a Purchaser’s Release in a manner that minimizes, to the maximum extent feasible, any material disruption of or interference with the operations of the Seller’s business.

(iii) Purchaser and Seller shall consult, and otherwise cooperate, with each other in good faith to assure that any Response conducted by either party is conducted as required by the provisions of this Section 12.3 and in a manner consistent with the requirements of Environmental Law.

(e) Negotiations with Governmental Agencies. The party performing a Response hereunder (the “Responsible Party”) shall have the right to negotiate and reach agreement with Environmental Authorities as to the nature, timing and scope of that Response provided that: (i) the Responsible Party shall share with the other party in a timely matter all material correspondence received from or submitted to an Environmental Authority relating to any Response hereunder; (ii) the Responsible Party shall afford the other party timely access to any non-privileged, material final studies, reports, protocols, drawings, charts, workplans, reports, risk assessments, schedules or other documentation relating to any Response; (iii) the Responsible Party shall provide the other party with timely notice of and an opportunity to attend and participate in any material meetings or in any hearings with Environmental Authorities (including, without limitation, material telephonic conferences) relating to any Response; and (iv) the Responsible Party shall consult with, and consider in good faith any comments of, the other party in preparing all material strategies and plans concerning a Response as contemplated hereunder. When planning or performing a Response to a Release, the Responsible Party shall not reach agreement with an Environmental Authority on a material element of that Response without the other party’s prior consent, which shall not be unreasonably withheld.

(f) Conduct of Response Actions. During any Response in or on the Eastman EPC Leased Property, the Responsible Party shall be solely responsible for compliance by that Party’s employees, contractors and subcontractors with all laws and professional standards applicable to its work.

(g) Investigations and Assessments.

(i) Without Seller’s prior written consent (to be granted at Seller’s sole discretion), Purchaser shall not conduct or arrange to have conducted a Voluntary or Discretionary Assessment of the Eastman EPC Leased Property or any property on or adjacent to Seller’s Longview, Texas facility. If Purchaser receives an Order from an Environmental Authority to conduct any type of assessment of the Environment at or around the Eastman EPC Leased Property or if Purchaser reasonably determines that it is required by Environmental Law to conduct such assessment, Purchaser shall notify Seller of the Order or of its determination within 48 hours after receiving the Order or making such a determination. Purchaser shall cooperate in good faith with Seller to minimize the scope of the assessment required by the Environmental Authority or Environmental Law.

(ii) In the event that Purchaser conducts a Voluntary or Discretionary Assessment of the Eastman EPC Leased Property or any property on or adjacent to Seller’s Longview, Texas facility without Seller’s prior written consent, Purchaser shall not be entitled to seek indemnification under Section 12.3(a)(iv) for Losses incurred (a) in the particular area that was investigated or assessed or (b) in any area subsequently investigated or remediated as a result of the Voluntary or Discretionary Assessment. Purchaser shall indemnify Seller for any Losses incurred by it as a result of any Voluntary or Discretionary Assessment performed in violation of this Section 12.3(g).

(h) Releases. Purchaser shall notify Seller immediately, and in no case more than 24 hours, after becoming aware of any Release of Hazardous Substances by Purchaser into the Environment, or the discovery by Purchaser of the presence of Hazardous Substances in the Environment in, on, around or emanating from the Eastman EPC Leased Property in such quantity, nature or condition that could reasonably be expected to (i) require a report to an Environmental Authority, (ii) require a Response under Environmental Law, or (iii) adversely affect human health (including but not limited to the safety of workers at the Eastman EPC Leased Real Property) or the Environment. Seller shall promptly notify Purchaser upon becoming aware of any Release that could reasonably be expected to adversely affect human health (including but not limited to the safety of on-site workers) at the Eastman EPC Leased Property.

(i) Exclusive Remedy. Except as otherwise provided in this Agreement and Exhibits hereto (including, but not limited to, the Ground Lease, the Other Agreements and the Services Agreement), the remedies provided under this Section 12.3 shall be the sole and exclusive remedies of the parties with respect to Losses arising under, related to or associated with, Environmental Laws and involving the Business, the Eastman EPC Leased Real Property and Seller’s Longview, Texas facility.

(j) Cost Sharing for Dallas/ Fort Worth SIP Compliance.

(i) Purchaser and Seller will work together to develop and agree upon the most cost-effective compliance strategy for the Business in meeting requirements associated with the forthcoming proposed amendments to 30 TAC Part 1 Chapter 117 as they relate to the implementation of certain nitrogen oxide emissions specifications for certain stationary,

gas-fired, reciprocating internal combustion engines in the forty-county area of east Texas (hereinafter referred to as the “Amendments”). Purchaser and Seller will work together to submit comments on the Amendments during the comment period in an attempt to mitigate the financial impact of the Amendments on both the Purchaser and Seller in light of the cost sharing agreement provided for in paragraph (ii) of this Section 12.3(j). In the event the Parties jointly retain a third party to assist them in commenting on the proposed Amendments or contesting any final Amendments, the Parties shall equally split the costs of retaining such third party.

(ii) Notwithstanding the provisions of paragraph (i) of this Section 12.3(j), in the event that Purchaser is required to incur capital costs (for example, costs to replace or modify any of the existing gas-fired engines used in the Business as of the Closing Date) in order to comply with the Amendments when and if they become effective, these capital costs, including but not limited to, the costs of replacing or modifying any engines (and the costs of any upgrading of any utilities to provide electric service to any of the newly installed electric engines) shall be allocated fifty percent (50%) to Seller and fifty percent (50%) to Purchaser.

(iii) Costs subject to the cost sharing agreement under paragraph (ii) of this Section 12.3(j) will be set forth in one of Purchaser’s Authorization for Expenditure (“AFE”) forms or comparable form (a copy of which is set forth in Exhibit M) that has been approved by Seller and Purchaser on or prior to December 31, 2008. The approval by Seller or Purchaser of an AFE will not be unreasonably withheld or unreasonably delayed. The parties acknowledge that it may be necessary to approve an AFE in advance of December 31, 2008 in order for a particular project to be installed to comply with deadlines required by the Amendments, but the parties agree that no AFE shall be issued or approved before the effective date of the Amendments. The cost sharing agreement under paragraph (ii) of this Section 12.3(j) will terminate on January 1, 2009 provided, however, that any funds set forth in an AFE that was approved prior to or on December 31, 2008 will be subject to the cost sharing agreement under paragraph (ii) of this Section 12.3(j) until such funds have been expended. In the event that the Amendments become effective but are subsequently stayed as a result of a challenge in litigation or in another applicable administrative proceeding, the term of the cost sharing agreement shall be tolled during that period of the stay and shall resume on the date that the stay is terminated and shall continue for the amount of time remaining in the term of the cost sharing agreement as of the start of the stay. Costs expended by Westlake during the tolling period to meet deadlines that are not stayed by any judicial or adminstrative challenge of the Amendments will be eligible for retroactive approval as part of an AFE. Once the cost sharing agreement under paragraph (ii) of this Section 12.3(j) is terminated, the responsibility for compliance by the Business with the Amendments shall be borne solely by Purchaser.

(iv) During the term of the cost sharing agreement under paragraph (ii) of this Section 12.3(j), the Parties shall attempt to resolve through informal negotiations any disputes between them involving the Dallas/Fort Worth Ozone Plan, including but not limited to what constitutes the most cost-effective strategy for complying with the Amendments, whether a particular cost should be included in an AFE, and whether a Party has unreasonably withheld or delayed its approval of an AFE . In the event the Parties cannot resolve such a dispute by informal negotiation, the dispute shall be governed by Article 7 of the Operating Agreement.

(v) This Section 12.3(j) and the cost sharing agreement provided herein shall terminate automatically and be deemed null and void in the event that Purchaser contracts to sell or sells or otherwise transfers the Business or assigns the Ground Lease between the parties to an unaffiliated third party, in which case, upon contracting to sell or otherwise transferring the Business or assigning the Ground Lease, the Purchaser shall immediately bear the full cost of complying with the Amendments and the Dallas/Fort Worth Ozone Plan as they affect the Business, and upon closing on such sale, transfer or assignment, the unaffiliated third party shall bear all such costs.

Section 12.4. Procedures for Indemnification. Whenever a claim shall arise for indemnification under Section 12.2 or Section 12.3, with the exception of claims under Section 12.3(a) and 12.3(b), which are governed by the terms of that Section, and with the exception of claims for litigation expenses in respect of litigation as to which a notice of claim, as provided in this Section 12.4, has previously been given, which expenses shall be funded on an ongoing basis, the Person entitled to indemnification (the “Indemnified Party”) shall promptly notify the party from which indemnification is sought (the “Indemnifying Party”) of such claim and, when known, the facts constituting the basis for such claim. In the event of any claim for indemnification hereunder resulting from or in connection with any claim or Proceeding by a third party, the Indemnified Party shall give such notice thereof to the Indemnifying Party not later than ten (10) Business Days prior to the time any response to the asserted claim is required, if possible, and in any event within fifteen (15) Business Days following receipt of notice thereof (provided that failure to notify the Indemnifying Party shall not relieve the Indemnifying Party of any liability it may have to the Indemnified Party, except to the extent that the Indemnifying Party has been actually prejudiced by such failure). Following receipt of notice of a claim or Proceeding by a third party, and unless counsel to the Indemnified Party shall have reasonably determined in good faith that the assumption of such defense by the Indemnifying Party would be inappropriate due to a conflict of interest, the Indemnifying Party shall have the option, at its cost and expense, to assume the defense of such matter and to retain counsel (not reasonably objected to by the Indemnified Party) to defend any such claim or Proceeding, and the Indemnifying Party shall not be liable to the Indemnified Party for any fees of other counsel or any other expenses (except as expressly provided to the contrary herein) with respect to the defense of such claim or litigation, other than reasonable fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense thereof. The Indemnified Party shall have the option of joining the defense of such claim or Proceeding (which shall be at the sole cost and expense of the Indemnified Party) with counsel not reasonably objected to by the Indemnifying Party and counsel for each party shall, to the extent consistent with such counsel’s professional responsibilities, cooperate with the other party and any counsel designated by that party. In effecting the settlement or compromise of, or consenting to the entry of any judgment with respect to, any such claim or Proceeding, the Indemnifying Party, or the Indemnified Party, as the case may be, shall act in good faith, shall consult with the other party and shall enter into only such settlement or compromise or consent to the entry of any judgment as the other party shall consent, such consent not to be unreasonably withheld, conditioned or delayed. An Indemnifying Party shall not be liable for any settlement, compromise or judgment not made in accordance with the preceding sentence.

ARTICLE XIV

TERMINATION

Section 14.1. Termination. This Agreement may be terminated and the transactions contemplated hereby abandoned any time prior to the Closing:

(a) upon the written agreement of Purchaser and Seller;

(b) by Purchaser or Seller if the other party shall have breached any representation, warranty, covenant or agreement contained herein that would result in the failure of the closing conditions set forth in Section 9.1 or Section 9.2, or Section 10.1 or Section 10.2, respectively, and such breach cannot be or has not been cured within thirty (30) calendar days after the giving of a written notice by the terminating party to the other party of such breach; and

(c) by Purchaser or by Seller if the Closing has not occurred on or prior to November 30, 2006 (subject to any extension of such date to accommodate the cure period under Section 14.1(b)); provided, however, that the right to terminate this Agreement under this Section 14.1(c) shall not be available to any party hereto whose failure to perform any covenant or obligation hereunder has caused or resulted in the failure of the Closing to occur on or before such date; provided, further, that in the event that all of the conditions of Articles IX and X have been satisfied or are capable of being satisfied, other than Sections 9.3 and 10.4, then neither party may terminate this Agreement under this Section 14.1(c) before January 31, 2007.

Section 14.2. Procedure and Effect of Termination. In the event of termination by either party under Section 14.1(b) or Section 14.1(c), written notice thereof shall be given to the other party and this Agreement shall terminate and the transactions contemplated hereby shall be abandoned, without further action by either party, upon delivery of such notice, except that the Confidentiality Agreement shall survive in accordance with its terms and Section 14.2, Section 15.2, Section 15.3, Section 15.4 and Section 15.7 shall also survive such termination. Upon any termination hereof pursuant to ARTICLE XIV, no party hereto shall thereafter have any further liability or obligation hereunder; provided, however, that no such termination shall relieve any party hereto of any liability for any willful breach of any term hereof prior to the date of such termination.
