Notwithstanding the foregoing or any other provision of this Agreement, neither the Purchaser nor any of its Affiliates shall be required either to exclude, sell or otherwise dispose of, or agree to or permit the exclusion, sale or other disposition of, any of the Assets or any assets of the Purchaser or its Affiliates, or to take any action or agree to any limitation that limits its freedom of action in the operation of the Assets or any assets of the Purchaser or its Affiliates, whether, in either case, as a condition to obtaining any approval from a Governmental Entity or any other Person or for any other reason.

(d) The Sellers shall give all notices to third parties (after having provided the Purchaser the opportunity to review and comment on such notices), and the Parties shall use commercially reasonable efforts (in consultation with one another) to (i) obtain all third-party approvals, consents, ratifications, waivers or authorizations (A) necessary to validly assign or convey the Assets to the Purchaser or otherwise consummate the transactions contemplated hereby, or (B) required to avoid a breach of or default under any Assumed Contract or Existing Easement in connection with the consummation of the transactions contemplated hereby (the “Required Consents”); (ii) obtain all Licenses (including any Environmental Permits and any pending applications for any Licenses or Environmental Permits) necessary for the Sellers to transfer the Assets to the Purchaser (collectively, the “Transfer Licenses”); (iii) transfer to the Purchaser or one of its Affiliates all Licenses that are transferable, such Licenses being set forth on Schedule 6.4(d) (the “Transferable Licenses”); and (iv) obtain all Licenses (including any Environmental Permits and any pending applications for any Licenses or Environmental Permits) necessary for the Purchaser’s lawful operation of the Assets following the Closing in substantially the same manner as presently operated by the Sellers (collectively, the “New Licenses”). The Purchaser and the Sellers shall, prior to and after the Closing, share equally (50/50) any commercially reasonable filing, administrative and other fees required to obtain such Required Consents, Transfer Licenses or Transferable Licenses.

(e) The Sellers shall provide a list of and access to the JCO-Wide Contracts to the Purchaser as promptly as practicable after the date hereof.

Section 6.5 Restricted Assets and Consents.

(a) To the extent the Closing of the transactions contemplated by this Agreement occurs notwithstanding the failure to obtain any Required Consent, Transfer License, Transferable License or New License or any other consent then:

(i) nothing set forth in this Agreement, nor any Seller Ancillary Document, will constitute an assignment, transfer, sublease, or sublicense of any Assumed Contract, Existing Easement or License (including any Environmental Permit or any pending application for any License or Environmental Permit) that requires the consent of the other party thereto or any other third party (including any Governmental Entity) (each such Asset, a “Restricted Asset”);

(ii) the Sellers or their Affiliate shall retain such Restricted Asset;

(iii) if such Restricted Asset is a Transfer License, Transferable License or New License, then to the extent permitted under the terms thereof, the Sellers shall use commercially reasonable efforts to provide the Purchaser or its Affiliate with the benefits of such Restricted Asset, including (if applicable) sublicensing such Restricted Asset to the Purchaser or its Affiliate;

(iv) if such Restricted Asset is an Assumed Contract or any Existing Easement (other than a Special Restricted Asset or an Existing Easement addressed in Section 6.5(b)), the Sellers shall use commercially reasonable efforts to provide the Purchaser or its Affiliate with the benefits of such Restricted Asset, including (if applicable) subcontracting, sublicensing or subleasing to the Purchaser or its Affiliate, and shall enforce and perform, at the request and expense of the Purchaser and for the benefit of the Purchaser or its Affiliate, any and all rights of the Sellers or their Affiliate against a third party thereto; and

(v) if such Restricted Asset is set forth on Schedule 6.5(a)(v) (each such asset, a “Special Restricted Asset”), the Sellers shall, to the extent not in violation of applicable Law, provide the Purchaser or its Affiliate with the benefits of such Special Restricted Asset, including subcontracting, sublicensing or subleasing to the Purchaser or its Affiliate, and shall enforce and perform, at the request and expense of the Purchaser and for the benefit of the Purchaser or its Affiliate, any and all rights of the Sellers or their Affiliate against a third party thereto.

In connection with the foregoing, (A) the Purchaser or its Affiliate shall promptly pay the Sellers’ or their Affiliate’s costs of satisfying any obligations and responsibilities accruing under such Restricted Asset that the Purchaser or its Affiliate would have otherwise incurred if the Required Consents had been obtained, and (B) with respect to any Assumed Contract that is a Restricted Asset, the Sellers shall promptly pay to the Purchaser or its Affiliate when received all monies received by the Sellers or their Affiliates in connection with such Restricted Asset or any claim or right or any benefit arising thereunder.

(b) With respect to any of the Easement Facilities (i.e., any pipeline or other facility), if, under the terms of any of the Existing Easements related to such Easement Facility consent is required prior to the assignment of such Existing Easement to the Purchaser and such consent has not been obtained prior to Closing, this Agreement shall not constitute an agreement to convey at the Closing such Existing Easement or the

portions of such Easement Facility that are located upon or related to such Existing Easement. In such case, the Parties agree that with respect to the portions of each Easement Facility not conveyed at the Closing, the Parties shall enter into a capacity rights purchase agreement substantially in the form of Exhibit F (the “Capacity Rights Purchase Agreement”) for the portion of the Easement Facility and the related portion of the Existing Easement for which such consent is required and that the other portions of such Easement Facility and the related Existing Easement shall be conveyed to the Purchaser at the Closing. Pursuant to any such Capacity Rights Purchase Agreement, the Purchaser shall have all capacity rights and the Purchaser shall have all operational responsibility and shall bear all ownership, operation, maintenance and other costs and risks of such Easement Facility and, to the extent related to such Easement Facility, the related Existing Easements and the use thereof, and shall defend and indemnify the Seller Indemnified Parties against all such costs and risks (other than those resulting from the gross negligence or willful misconduct of the Sellers). The Purchaser shall make all filings necessary to be named the operator of all the Easement Facilities and to obtain and hold all Licenses relating to the Easement Facilities. With respect to any Easement Facility and related Existing Easements to which the Capacity Rights Purchase Agreement applies, when the applicable consents are obtained, the Sellers shall convey such Easement Facility and assign such Existing Easements to the Purchaser within ten days following receipt of such consents, and the Capacity Rights Purchase Agreement with respect to such Easement Facility shall terminate. During the term of any such Capacity Rights Purchase Agreement, the Sellers shall not convey, or allow any Liens by, through, or under the Sellers to attach to, the applicable Easement Facility or Easements covered by such Capacity Rights Purchase Agreement. Additionally, the Purchaser may terminate such Capacity Rights Purchase Agreement at any time by giving sixty (60) days’ notice. At the time of termination of the Capacity Rights Purchase Agreement, the applicable Sellers shall convey and shall cause their Affiliates to convey to the Purchaser or its nominee, directly or indirectly, without warranty, the remaining rights they may have in the Easement Facilities and, to the extent related to such Easement Facilities, the Existing Easements. At the Purchaser’s request, the Sellers and the Purchaser shall jointly evaluate the permissibility of (i) transferring to a newly formed special purpose corporation or limited liability company (the “Easement SPV”), any of the easements that are subject to the Capacity Rights Agreement; (ii) having the Purchaser purchase all of the equity interest in the Easement SPV for the payment of $1.00; and (iii) terminating the Capacity Rights Agreement with respect to the easements owned by the Easement SPV. If the Parties determine that the terms of any of the easements that are subject to the Capacity Rights Agreement permit such an arrangement, at Purchaser’s request, the Parties will implement such arrangements with respect to such easements on terms to be reasonably agreed to by the Parties.

(c) The Sellers shall continue after the Closing to use all commercially reasonable efforts to obtain any Required Consent, Transfer License, Transferable License or any other consent that was not obtained prior to the Closing. During the term of the Capacity Rights Purchase Agreement, with respect to any Easements and Easement Facilities covered thereby, the Purchaser shall not take any action to obtain any Required Consents without the prior written consent of the Sellers.

Section 6.6 Public Announcements. The Parties shall not issue any press release or public announcement concerning this Agreement or the transactions contemplated hereunder without obtaining the prior written approval of the other Party hereto, which approval will not be unreasonably withheld or delayed, unless, in the sole judgment of the Purchaser or the Sellers, as applicable, disclosure is otherwise required by (i) applicable Law, or (ii) by the applicable rules of any stock exchange on which the Purchaser or the Sellers lists securities, provided, that to the extent required by applicable Law, the Party intending to make such release shall use its commercially reasonable efforts consistent with such applicable Law to (a) consult in good faith with the other Party with respect to the timing and content thereof (including giving due consideration to all reasonable additions, deletions or changes suggested in connection therewith) and (b) provide a copy thereof to the other Party prior to such issuance.

Section 6.7 Employees.

(a) Transferred Employees. The Purchaser shall offer employment to each Business Employee set forth on Schedule 6.7(a)-1. The Purchaser shall have the option to offer employment to each Business Employee set forth on Schedule 6.7(a)-2. Business Employees who accept such offers are, as of the Closing Date, referred to herein as “Transferred Employees.” Subject to the provisions of any Labor Agreements, for a period of at least 12 months after the Closing Date, the Purchaser shall provide each Transferred Employee with base wages and/or salaries not less than those in effect immediately prior to the Closing Date and with benefits that are not less than those provided to similarly situated employees of the Purchaser.

(b) Employee Communications. Prior to the Closing, the Sellers shall share with the Purchaser any written communication the Sellers intend to distribute to a group of Business Employees regarding the transaction contemplated in this Agreement. The Sellers shall share these written communications with the Purchaser as soon as practicable before distribution to the Business Employees, and with sufficient time for the Purchaser to raise any issues it may have with the communication prior to distribution. Also, prior to the Closing, the Sellers and the Purchaser shall cooperate with one another in facilitating an orderly process for those Business Employees accepting offers of employment from the Purchaser so that their employment with the Purchaser will be effective as of the Effective Time if the Closing occurs. From the date of this Agreement until the Closing, the Sellers shall afford the Purchaser with reasonable access to the Business Employees in order to make and finalize its offers of employment; provided, however, that any such access or availability shall be provided during normal business hours upon reasonable advance notice to the Sellers, and in such a manner as to not unreasonably interfere with the normal operations of the Sellers.

(c) Seller Benefit Plans. The Sellers shall retain, and the Purchaser shall have no liability with respect to, the Seller Benefit Plans.

(d) Severance. The Purchaser shall establish and maintain for a period of not less than 12 months from the Closing Date (for the benefit of the Transferred Employees), a severance program providing to Transferred Employees who leave the employ of the Purchaser and its Affiliates at any time during the 12-month period after

the Closing for any reason other than through death, disability, discharge for cause (including, but not limited to, negative results on a drug test or background check administered after the Closing) or the employee’s voluntary act, severance benefits that are at least equal to those provided under the Sellers’ applicable severance programs, copies of which have been provided to the Purchaser. With respect to those Business Employees listed on Schedule 6.7(a)-2 who do not become Transferred Employees, the Purchaser and the Sellers agree that they will contribute equally to the payment of severance benefits (as provided under the Sellers’ applicable severance programs, copies of which have been provided to the Purchaser) that are payable to those Business Employees whose employment with the Sellers, or with any Affiliate of the Sellers, ends within six months after the Closing Date, provided, however, with respect to any such Business Employees who are re-employed by the Sellers or any Affiliate of the Sellers within six months of the end of his employment, the Sellers shall promptly return to the Purchaser the amount of severance paid to such Business Employee and borne by the Purchaser.

(e) COBRA Coverage. The Sellers shall be solely responsible for offering and providing any COBRA Coverage with respect to any of the Business Employees who is a “qualified beneficiary,” who is covered by a Seller Benefit Plan that is a “group health plan” and who experiences a “qualifying event” on or prior to the Closing Date for the transfer of such Business Employee. The Purchaser shall be solely responsible for offering and providing any COBRA Coverage required with respect to any Transferred Employee (or other qualified beneficiary), who becomes covered by a group health plan sponsored or contributed to by the Purchaser, and who experiences a qualifying event subsequent to the Closing Date for the transfer of such Transferred Employee. For purposes hereof, each of “qualified beneficiary”, “group health plan” and “qualifying event” shall have the meaning ascribed thereto in Section 4980B of the Code.

(f) Service Credit. For purposes of eligibility, vesting, and benefit accrual under the benefit plans of the Purchaser providing benefits to Transferred Employees, the Purchaser shall credit each such Transferred Employee with his or her years of service credited by the Sellers or their Affiliates (in accordance with the provisions of the Sellers’ or their Affiliates’ benefit plans and policies as they are in effect as of the date of this Agreement), to the same extent as the Transferred Employee was entitled immediately prior to the Closing to credit for such service under any similar benefit plan of the Sellers or their Affiliates; provided, however, that the applicable Purchaser defined benefit plan shall provide that the Transferred Employee’s accrued benefit thereunder shall be offset or reduced by such Transferred Employee’s accrued benefit under the Huntsman Defined Benefit Pension Plan (including any credit under any applicable Chevron/Texaco pension benefit) and the Huntsman Local No. 436 G-U.S.W.A.I.U. Hourly Rated Employees’ Pension Plan (as applicable) as of the Closing Date; but in no event shall a Transferred Employee’s accrued benefit under the applicable Purchaser’s plan be less than the amount determined under such plan’s benefit formula without consideration of service credited by the Sellers and their Affiliates (in accordance with the provisions of the Sellers’ or their Affiliates’ benefit plans and policies as they are in effect as of the date of this Agreement) prior to the Closing Date and without reduction for the Transferred Employee’s accrued benefit under the applicable Seller’s plan. The benefit plans of the

Purchaser shall not deny Transferred Employees coverage or benefits on the basis of pre-existing conditions and shall credit such Transferred Employees for any deductibles and out of pocket expenses paid in the year of initial participation in the benefit plans of the Purchaser, provided such Transferred Employees elect to participate in the benefit plans of the Purchaser when first eligible to do so. As soon as practicable, but in any event not later than 180 days after the Closing (and, with respect to any Transferred Employee who terminates employment with the Purchaser before such time, as soon as practicable following a request from the Purchaser), the Sellers shall provide the Purchaser with such information in the possession of the Sellers that the Purchaser may reasonably require to carry out its obligations under this Section 6.7(f), and shall otherwise cooperate with the Purchaser with respect to such obligations.

(g) Retiree Health Plan. The Sellers shall take or cause to be taken such actions with respect to its retiree health plan as necessary to provide that each Transferred Employee who (i) on the Closing Date is eligible to retire from the Sellers and receive coverage under the Sellers’ retiree health plan or (ii) would become so eligible prior to the “applicable date” if his continuous employment with the Purchaser following the Closing were deemed to be continued employment with the Sellers, shall, on his termination from the Purchaser, be eligible to elect, to the extent the Sellers then maintain a retiree health plan, to receive coverage under the Sellers’ retiree health plan as if he had retired directly from the Sellers. The “applicable date” shall mean (A) the end of the term of the collective bargaining period in effect on the Closing, if the Transferred Employee is covered by a Labor Agreement and (B) January 31, 2009, if the Transferred Employee is not covered by a Labor Agreement. However, nothing herein shall operate or be construed to prevent the Sellers from amending or terminating their retiree health plan at any time following the Closing, provided that (1) the Sellers, either through Sellers’ retiree health plan or otherwise, will ensure that the same coverage as described in this subsection is provided to each eligible Transferred Employee whose employment terminates by the “applicable date” at least through the “applicable date” and (2) the Sellers will not eliminate or materially adversely change, prior to the “applicable date,” the coverage provided for in the Sellers’ retiree health plan for any employees whose employment terminates prior to the Closing Date and had been covered by a Labor Agreement when employed by the Sellers. This paragraph is not intended to be, and shall not be construed as, an amendment to the Sellers’ retiree health plan.

(h) Information. The Sellers shall assist the Purchaser in connection with the transfer of employment of the Business Employees, including, to the extent permitted by Law, by providing all information relating to each Business Employee as the Purchaser may reasonably require (including initial employment dates, termination dates, reemployment dates, attendance records, personnel and status records, hours of service, compensation and tax withholding history). The Sellers shall exercise reasonable efforts to facilitate communication after the date hereof between the Purchaser and representatives of Union Employees.

(i) WARN. The Purchaser shall be liable for any liability under WARN or any similar state or local law for any terminations of Business Employees occurring on or after the Closing Date.

Section 6.8 Labor Matters. The Purchaser acknowledges that one or more of the Sellers is party to the Labor Agreements. From and after the Closing Date, the Purchaser shall recognize the applicable unions as the exclusive representative of applicable bargaining units, as defined in the Labor Agreements, and shall adopt the Labor Agreements, except as otherwise provided in any agreements between the Purchaser and the applicable unions. If requested by the applicable union, the Purchaser shall negotiate with the applicable union in good faith regarding the package of employee benefits it provides to Union Employees. In adopting the Labor Agreements, the Purchaser takes note of the applicable successorship provisions, which provide, subject to the union’s right to demand bargaining stated above, that a successor company shall not be required to continue the existing employee benefits provided by the Sellers, but shall be entitled to establish a package of benefits that are reasonably comparable in the aggregate, or to waive such commitment if certain provisions are met.

Section 6.9 Risk of Loss. The risk of loss shall remain with the Sellers until the Closing, at which time such risk shall pass to the Purchaser. In the event of any material loss, damage, impairment or confiscation of any of the Assets prior to the passage of risk of loss with respect to such Asset, the Sellers at their option shall either (i) repair, replace or restore such property as soon as practicable after such loss, damage, impairment or condemnation, or (ii) if insurance proceeds or any judgment or awards (together with any deductibles or self-retention amount paid by the Sellers) received by the Sellers would reasonably be expected to be sufficient to repair, replace or restore the property, pay such proceeds, judgment or award (together with the amount of any applicable deductibles or self-retention amount) to the Purchaser on the Closing Date for such Asset.

Section 6.10 Site Matters.

(a) The Sellers shall provide to the Purchaser copies of their title commitments, title policies and surveys listed on Schedule 6.10(a) (the “Existing Title Information”) relating to the Conveyed Sites. The Purchaser may obtain, at its cost, and for its and any of its lenders’ benefit, title policies (“Purchaser Title Policies”) and surveys (“Surveys”) with respect to any Conveyed Site. The Sellers shall reasonably cooperate with the Purchaser by providing access to the Conveyed Sites, the Easements, and the Sellers’ property records for the purpose of obtaining Purchaser Title Policies and Surveys but, subject to Section 6.2 and Section 6.10(b) below, shall not be obligated to undertake any cost or obligation in connection therewith.

(b) The Parties acknowledge and agree that (i) the Port Arthur Site will be conveyed to the Purchaser at the Closing with reservations of easements, leasehold rights, other surface use rights and rights-of-access in favor of the Sellers providing for the locating of and access to the pipelines, tanks, electrical transmission lines, other facilities and effluent streams that are described on Schedule 6.10(b)-1 as being retained by the Sellers from and after the Closing together with any pumps and other equipment associated therewith (the “Seller Retained Easements”) and (ii) the Sellers will convey, and as necessary cause their Affiliates to convey, to the Purchaser at the Closing easements to the extent necessary across lands owned by the Sellers providing for the locating of and access to the Easement Facilities described on Schedule 6.10(b)-2 (the “Additional Conveyed Easements”). From and after the date hereof until the Closing,

the Sellers and the Purchaser shall cooperate in and share the out-of-pocket third-party survey costs of identifying the property covered by the Seller Retained Easements and the Additional Conveyed Easements, together with the costs of the surveys. Such costs shall be borne 50% by the Purchaser and 50% by the Sellers.

Section 6.11 Post-Closing Access to Retained Books and Records.

(a) It is acknowledged by the Parties that the Retained Books and Records and the books and records included in the Assets may include information relating to the business of, or otherwise be of interest to, the Party not in possession of such items and that the respective Parties should be provided reasonable access to such information after the Closing. Accordingly, for a period of seven years after the Closing Date, each Party shall (and shall cause its Affiliates to) maintain and allow the other Party and its authorized representatives reasonable access to all Retained Books and Records relating to the Business and the books and records included in the Assets, as applicable, upon prior written notice and during normal working hours at the location where such Retained Books and Records or books and records included in the Assets, as applicable, are stored, and such other Party shall have the right, at its own expense, to make copies of such materials; provided, however, that any such access or copying shall be had or done in such a manner so as not to unreasonably interfere with the normal conduct of the Party’s business. Notwithstanding the foregoing, the Parties may destroy the Retained Books and Records and the books and records included in the Assets in a manner consistent with their respective document retention policies.

(b) Without limiting the Sellers’ obligations under Section 2.2, it is further acknowledged by the Parties that data or information relating to the Business, or copies thereof, may be retained in the Sellers’ paper files, electronic storage media or otherwise. From and after the Closing Date, the Sellers will safeguard the confidentiality of any such data and information to the same extent as the Sellers safeguard the confidentiality of the Retained Books and Records.

(c) It is further acknowledged that information technology transition matters, including the timing of, formatting for and other specifics regarding delivery of books and records included in the Assets shall be governed by the terms and provisions of the Transition Services Agreement to the extent the Transition Services Agreement specifically addresses such matters in lieu of this Section 6.11.

Section 6.12 Litigation Support. In the event and for so long as any Party or any Affiliate thereof (or any person or entity indemnifying the Party or Affiliate) actively is contesting or defending any action, suit, proceeding, hearing, investigation, charge, complaint, claim, demand or grievance by a third party (other than a criminal action or investigation brought by a Governmental Entity) in connection with (a) any transaction contemplated under this Agreement or (b) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act or transaction on or prior to the Closing (or after the Closing, if the Sellers are implicated) relating to or involving the Business, the Assets, the Business Employees, the Assumed Liabilities or the Retained Liabilities, then the other Party will reasonably cooperate with such contest or defense and will make reasonably available its

personnel, records and information applicable to such matter as may be necessary in connection with prudent handling of such contest or defense; provided, however, that, unless otherwise entitled to indemnification therefor pursuant to this Agreement, the contesting or defending Party shall reimburse the other Party for the reasonable out-of-pocket costs of such efforts; provided further, however, that such other Party shall have notified the contesting or defending Party in writing prior to incurring any material amount of such costs. This Section 6.12 is in addition to, and does not in any way limit, the rights or obligations of any Party pursuant to Article XII of this Agreement.

Section 6.13 Use of Names and Trademarks.

(a) Except as set forth in Section 6.13(b) below, after the Closing, neither the Purchaser nor any of its Affiliates shall use or otherwise exploit any name incorporating “Huntsman” or any derivation thereof that would reasonably be expected to be confused therewith (the “Huntsman Name”), or any other tradenames, domain name, trade dress, trademark or service mark confusingly similar thereto.

(b) As promptly as practicable but in no event later than six (6) months following the Closing Date (the “Phaseout Period”), the Purchaser shall remove or otherwise obliterate the Huntsman Name from all materials owned by the Purchaser or its Affiliates, including any buildings, vehicles, equipment, business cards, schedules, stationery, packaging materials, displays, signs, promotional materials, advertising, manuals, forms, computer software and other materials or fixed assets; provided, that the Purchaser (i) shall not be obligated to remove or otherwise obliterate the Huntsman Name (A) prior to the end of the Phaseout Period, (B) with respect to displays of the Huntsman Name on equipment (but not buildings, vehicles, signs and storage tanks) that is not reasonably likely to be seen by the public or cannot be seen by the public without unlawful entry on the applicable location of such equipment and if it is commercially unreasonable to remove or otherwise obliterate, or (C) from all books and records (but not stationery, promotional materials and advertising) and all archived materials, technical drawings, invoices and manuals; (ii) shall have the right to sell existing Inventory (on hand or in transit as of the Closing Date) and to use existing packaging, labeling, containers, supplies, advertising materials, technical data sheets and any similar materials bearing the Huntsman Name until the earlier of (A) the expiration of the Phaseout Period, and (B) the date existing stocks are exhausted; and (iii) shall have the right to use the Huntsman Name in connection with the transition of email services of the Business until three (3) months after the Closing Date. The Purchaser shall comply with all applicable Laws and regulations and policies of the Sellers in any use of the Huntsman Name. Compliance with the terms of this Section 6.13(b) shall be deemed compliance with the covenant not to use the Huntsman Name pursuant to Section 6.13(a) with respect to the Huntsman Name used on the Assets as of the Closing. During any period that the Purchaser is using the Huntsman Name as provided in this Section 6.13(b), it shall take commercially reasonable steps to inform customers, suppliers and contractors that it is not part of the Sellers and is using the Huntsman Name with permission solely to facilitate the transition of the Business. Notwithstanding anything to the contrary, the Purchaser and its Affiliates shall have no right to create any new materials containing the Huntsman Name.

(c) For a 180-day period following the Closing, each Seller will, and will cause its Affiliates to refer all customer and supplier inquiries relating to the Business to the Purchaser, except to the extent the Sellers or their Affiliates otherwise have access to products requested by customers.

Nothing contained in this Section 6.17(b) shall prohibit the Sellers or the Purchaser from employing any person as a result of a general solicitation to the public or general advertising.

(c) From and after the Closing Date, except as permitted by the Cross License Agreement, the Sellers shall not and shall cause their Affiliates and their respective officers, and directors not to, directly or indirectly, disclose, reveal, divulge or communicate to any Person other than authorized officers, directors and employees of the Purchaser or use or otherwise exploit for its own benefit or for the benefit of anyone other than the Purchaser, any Business Intellectual Property that comprises trade secrets or confidential information owned by the Sellers. The Sellers and their officers, directors and Affiliates shall not have any obligation to keep confidential any such Business Intellectual Property that comprises trade secrets or confidential information owned by the Sellers if and to the extent disclosure thereof is specifically required by Law; provided, however, that in the event disclosure is required by applicable Law, the Sellers shall, to the extent reasonably possible, provide the Purchaser with prompt notice of such requirement prior to making any disclosure so that the Purchaser may seek an appropriate protective order.

(d) The covenants and undertakings contained in this Section 6.17 relate to matters which are of a special, unique and extraordinary character and a violation of any

of the terms of this Section 6.17 will cause irreparable injury to each non-defaulting Party, the amount of which will be impossible to estimate or determine and which cannot be adequately compensated. Accordingly, the remedy at law for any breach of this Section 6.17 will be inadequate. Therefore, any Party will be entitled to an injunction, restraining order or other equitable relief from any court of competent jurisdiction in the event of any breach of this Section 6.17 without the necessity of proving actual damages or posting any bond whatsoever. The rights and remedies provided by this Section 6.17 are cumulative and in addition to any other rights and remedies which the Parties may have hereunder or at Law or in equity.

Section 6.18 Receivables and Payables. After the Closing, the Sellers shall use commercially reasonable efforts to timely pay all Payables as they become due. In the event that there is a dispute as to the amount, time of payment, or any other issue in connection with a Receivable or Payable after the Closing, the Sellers shall notify the Purchaser of such dispute in a timely manner and prior to the commencement of any collection proceeding by the Sellers and the Purchaser shall use its commercially reasonable efforts to cooperate with the Sellers to resolve such dispute to the Sellers’ reasonable satisfaction.

Section 6.19 Customer Access. During the period commencing on the date hereof and ending on the Closing Date, the Sellers shall use commercially reasonable efforts to arrange for the Purchaser to meet or otherwise communicate with any customer of the Business. Without the prior consent of the Sellers, the Purchaser shall not arrange any such meetings itself or make any contact with such Persons for the purpose of discussing the Business or any Assumed Contract; provided, however, nothing herein shall preclude the Purchaser from having contact of any nature with any such Person for any other purpose, including to discuss existing business that the Purchaser may have with any such Person or potential future business not related to the Business. One or more employees or representatives of the Sellers may accompany the Purchaser’s representative to such meetings (other than those described in the proviso to the preceding sentence) and may participate with the Purchaser’s representative in any related discussions. Satisfaction by the Purchaser with the results of any such meeting or discussions with any such Person in respect of the Business shall not be a condition precedent to its obligations to close the transactions contemplated hereunder. Notwithstanding the foregoing provisions, the foregoing activities shall only be permitted to the extent permitted by applicable Law.

Section 6.20 Fenceline Monitoring at Port Arthur Site. Huntsman Petrochemical is subject to an Agreed Final Judgment (“Agreed Judgment”) in the case of State of Texas v. Huntsman Petrochemical Corporation, No. GV301473 (D.Ct. Travis County, Texas), pursuant to which Huntsman Petrochemical, under the terms of a Supplemental Environmental Project, is obligated to monitor and report airborne concentrations of certain chemicals along the fenceline of the Port Arthur Site. If Huntsman Petrochemical has not completed its obligations pursuant to the Agreed Judgment prior to the Closing Date, the Purchaser shall cooperate with Huntsman Petrochemical in arranging for completion of those activities required by the Agreed Judgment that have not been completed to the satisfaction of the State of Texas. Without limiting the foregoing, the Purchaser shall (a) provide electricity to and security for the fenceline monitoring system, (b) provide Huntsman Petrochemical and its contractor with access to the fenceline monitoring system and restrict the access of other Persons to the fenceline monitoring system,

(c) notify Huntsman Petrochemical of any tampering the Purchaser discovers or becomes aware of with respect to the fenceline monitoring system, including any unauthorized attempts to access any part of the fenceline monitoring system by anyone other than personnel authorized in writing by Huntsman Petrochemical, (d) respond to all reasonable requests from Huntsman Petrochemical or the Texas Commission on Environmental Quality for information relating to the fenceline monitoring program or the Agreed Judgment, and (e) not take any action that would interfere with, damage, or disturb the fenceline monitoring system or otherwise take any action to impair its functionality during the period that the Agreed Judgment is in effect. Following completion of the actions required by the Agreed Judgment, whether such actions are completed before or after Closing, Huntsman Petrochemical shall, at the later of (i) the Closing or (ii) the date such actions are completed, convey title to and responsibility for the equipment to the Purchaser (at no cost to the Purchaser), or, at the Purchaser’s election, Huntsman Petrochemical shall remove any or all equipment used in connection with the monitoring program.

Section 6.21 Port Arthur Performance Test; LOU Facility. The Sellers will use commercially reasonable efforts to complete the rebuild work on the LOU Facility and satisfy the Performance Test as promptly as practicable. If the Purchaser demonstrates (as validated by an independent engineer) that the LOU Facility is not capable of operating on a sustained basis at rates that are 99% or more of its average production rates during the 2004 calendar year and such failure is as a result of any defect in the engineering or in the workmanship or materials with respect to the rebuild of the LOU Facility that has appeared within one year of the Closing Date, then the Sellers shall reimburse the Purchaser or its Affiliates for all payments made to contractors to repair such defect, whether such repairs are covered by third party warranties or not. The reimbursement obligation in the foregoing sentence shall be limited by the following: (i) the Purchaser shall first pursue, and shall cause its Affiliates to pursue, by all commercially reasonable means short of litigation, all claims and rights with respect to any warranty claims under the Rebuild Agreements; and, (ii) the Sellers’ aggregate reimbursement obligation shall be limited to $15,000,000 and shall be reduced by any amounts recovered by the Purchaser from contractors under the Rebuild Agreements. The Purchaser agrees not to amend any of the terms of the Rebuild Agreements in any manner that reduces the scope of the warranties available under such Rebuild Agreements. The Purchaser agrees to assign all its rights and claims against contractors with respect to amounts paid or reimbursed by the Sellers. The Sellers shall make reimbursement required under this Section 6.21 within thirty (30) days of invoice by the Purchaser or its Affiliates.

Section 6.22 Other Property.

(a) Notwithstanding anything to the contrary contained in this Agreement, the Purchaser shall have the option to exclude the Longview Owned Site from the Assets, in which case the Longview Owned Site shall be an Excluded Asset for all purposes set forth herein. The Purchaser’s option to exclude the Longview Owned Site shall expire on the date which is thirty (30) days from the date hereof and may be exercised by providing notice to the Sellers before the end of such 30-day period.

(b) The Purchaser shall have the option to purchase the real property identified on the map attached as Schedule 6.22(b). The Purchaser’s option shall expire on the date which is thirty (30) days from the date hereof and may be exercised by

providing notice to the Sellers before the end of such 30-day period. If the Purchaser exercises such option, at the Closing the applicable Seller shall convey all of its right, title and interest in and to such real property pursuant to a deed containing a special warranty of title and without representation, warranty or indemnity under this Agreement except for the representation and warranty set forth in Section 4.4(e).

ARTICLE VII

TAX MATTERS

Section 7.1 Allocation of Purchase Price. Attached as Schedule 7.1 is an allocation of the Purchase Price and the Assumed Liabilities among the Assets. Schedule 7.1 is intended to be consistent with the requirements of Sections 1060 and regulations promulgated thereunder (the “Allocation Statement”). The Purchaser and the Sellers shall cooperate with one another in good faith to make any needed modifications to the Allocation Statement to reflect any adjustments to or final determination of the amount of the Assumed Liabilities or the value of the Inventory, and subject to such modifications the Sellers and the Purchaser agree to file all Tax Returns (including filing Internal Revenue Service Form 8594) consistent with the Allocation Statement.

Section 7.2 Transfer Taxes. Any sales, use or transfer Taxes or recording fees payable as a result of the transactions contemplated by this Agreement shall be borne equally by the Purchaser and the Sellers. The Parties shall cooperate in the preparation, execution and filing of all returns, questionnaires, applications and other documents regarding transfer Taxes and all transfer, recording, registration and other fees that become payable in connection with the transactions contemplated hereby that are required or permitted to be filed at or prior to the Closing. The Sellers and the Purchaser shall use their commercially reasonable efforts to obtain any certificate or other document from any Governmental Entity or any other Person as may be necessary to mitigate, reduce or eliminate any sales, use or transfer Taxes with respect to the transactions contemplated by this Agreement.

Section 7.3 Certificate of Non-Foreign Status. At the Closing, each Seller (other than Huntsman Canada) shall deliver to the Purchaser a certificate of non-foreign status of such Seller which meets the requirements of Treasury Regulation Section 1.1445-2(b)(2).

ARTICLE VIII

ENVIRONMENTAL MATTERS

Section 8.1 Environmental Indemnification by the Sellers.

(a) Subject to the provisions of this Article VIII, from and after the Closing Date the Sellers shall, jointly and severally, indemnify and hold harmless the Purchaser Indemnified Parties from and against, and shall reimburse the Purchaser Indemnified Parties for, all Losses that the Purchaser Indemnified Parties incur resulting from or arising out of the following (collectively, “Seller Environmental Liabilities”):

(i) any Indemnifiable Assumed Liabilities;

(ii) any Longview Environmental Contamination;

(iii) any Peru Environmental Contamination;

(iv) any Off-Site Disposal Activities;

(v) any breach of the Sellers’ representations and warranties set forth in Section 4.17 (“Environmental Rep Breaches”); and

(vi) any breach of the Sellers’ obligations in this Article VIII.

(b) In the event that a Purchaser Indemnified Party becomes aware of any claim, suit, action, litigation, arbitration, audit, hearing, investigation, inquiry or other proceeding by a Governmental Entity or other Person or other occurrence that may potentially result in indemnification for any Seller Environmental Liabilities or in Losses in excess of $25,000 that would count towards the Environmental Deductible, the Purchaser Indemnified Party shall, as soon as reasonably practicable after becoming aware of such occurrence, notify the Sellers in writing of such occurrence (a “Purchaser Environmental Indemnity Claim”). The failure by the Purchaser to timely provide such notice shall not affect the right of the Purchaser to indemnification pursuant to this Article VIII, except to the extent the Sellers are prejudiced by any failure by the Purchaser to provide sufficient and timely notice of the occurrence and the Purchaser’s proposed response.

(c) In the event of an indemnity claim by either Party involving Remediation, for which either Party is entitled to indemnification pursuant to this Article VIII, the Managing Party shall have the right, but not the obligation, to manage all matters arising out of, and perform all Remediation and other corrective actions, resulting from or relating to such Remediation as follows:

(i) The Managing Party shall manage all matters, and perform all Remediation and other corrective actions, arising out of, resulting from or relating to, such Remediation, but shall provide Meaningful Participation Rights to the other Party. Such management may include the conduct of and final decision-making regarding all studies, monitoring, and remedial activities, and any and all other activities for the purpose of investigating, remedying, settling or otherwise addressing the Remediation, and shall include the right and responsibility for dealing with all Governmental Entities concerning the Remediation.

(ii) In the event that any Seller is the Managing Party conducting Remediation on a Site, Easement, or Facility owned or operated by the Purchaser, such Seller shall use all commercially reasonable measures to minimize interference with the Purchaser’s operation of the Business in connection with its management of or other activities associated with the Remediation, and shall not interfere with the Purchaser’s operation of the Business without the Purchaser’s prior written consent (which shall not be unreasonably withheld, conditioned or delayed). The Sellers also shall take all commercially reasonable measures to ensure that the Sellers and their respective agents and representatives follow the

Purchaser’s reasonable safety and operational procedures, and do not create or increase an enforcement risk for the Purchaser associated with its operations. The Sellers’ activities with regard to the Remediation shall be subject to reasonable limitations on access to the Sites or Easements, giving due consideration for the nature of the activity, the urgency of or immediate need for action, site security requirements, standard site operating procedures, and any specific requirements of a Governmental Entity.

(iii) The Managing Party, upon the request of the other Party, shall retain counsel chosen by the other Party to represent the other Party in connection with the Remediation, and the Managing Party shall pay the fees and expenses of any such counsel, provided, that counsel selected by the other Party shall be reasonably acceptable to the Managing Party, such acceptance not to be unreasonably withheld, conditioned or delayed.

(iv) The Party that is not the Managing Party will cooperate with and assist, and shall not interfere with, the Managing Party’s management, performance, decision-making or negotiations with respect to the Remediation, subject to the Meaningful Participation Rights of the Party that is not the Managing Party. Notwithstanding the foregoing, nothing in this Section 8.1(c) shall limit or restrict either Party’s ability to report or disclose information to Governmental Entities or other third parties that such Party reasonably believes is required to be disclosed under applicable Laws, or to take such actions as may be necessary to comply with applicable Laws.

(v) The Managing Party shall be responsible for securing at its own cost and expense all Environmental Permits and other Licenses (including any that may be in the other Party’s name) required in connection with the Remediation, and the Party that is not the Managing Party shall cooperate and join with the Managing Party to procure such approvals, including joining in and executing any necessary permit applications and supplying documentation or witnesses reasonably required therefor.

(vi) The Managing Party’s obligations with respect to the Remediation shall include all actions necessary or appropriate to resolve such claims in a manner sufficient to (1) obtain a “no further action” letter or similar document, or other evidence of approval from the relevant Governmental Entity, or (2) if the relevant Governmental Entity does not issue a “no further action” letter or similar document or approval, or the claim is not of the character that would result in the issuance of such a letter, document or approval, then bring the operation or condition that is the subject of the Remediation into compliance with all applicable Environmental Laws.

(d) The Sellers shall not be obligated to indemnify and hold harmless the Purchaser Indemnified Parties from and against Losses resulting from, based upon or arising out of Seller Environmental Liabilities of the type described in Sections 8.1(a)(i)–(iii) and (v) involving Remediation, except to the extent that such Remediation is:

(x) undertaken (A) to satisfy the terms of an official order or directive issued by a Governmental Entity pursuant to any Environmental Law, or (B) to satisfy a payment obligation to a third party for Remediation; and (y) not incurred by the Purchaser Indemnified Parties as a result of any instigation, encouragement, action, failure or change of the types set forth in items (1)–(8) set forth below:

(1) any investigation, claim or proceeding initiated or instituted by any Governmental Entity or any other Person that is instigated or encouraged, directly or indirectly, by a Purchaser Indemnified Party, unless such claim or proceeding arose out of the submission of a report to a Governmental Entity that was required by applicable Law;

(2) any sampling or other investigation of environmental conditions at any of the Sites or the Easements, except for those investigations required to be performed pursuant to applicable Environmental Laws or pursuant to the order or directive of any Governmental Entity and except to the extent provided in subsection 8.1(e);

(3) any demolition of existing structures or development of new structures at the Sites or the Easements requiring removal or disturbance of soil beneath the ground surface, except to the extent provided in subsection 8.1(e);

(4) any post-Closing change in use of any of the Sites or Facilities to anything other than industrial, manufacturing, or chemical industry uses (provided, however, that the shutdown of use of a Facility shall not be deemed a change of use hereunder so long as public access to the Site or Facility remains restricted in a manner consistent with ongoing industrial, manufacturing or chemical industry uses);

(5) the failure of any Purchaser Indemnified Party to cooperate with the Sellers in a commercially reasonable manner in addressing such Losses, to the extent such failure to cooperate in a commercially reasonable manner is the proximate cause of any increase in or exacerbation of such Losses;

(6) any of the activities set forth in items (1), (2), (3) and (5) above by any Purchaser Indemnified Party on any property adjacent to the Sites or Easements, whether before or after the Closing;

(7) any change in Environmental Laws after the Closing;

(8) any failure of the Purchaser to comply with any environmental restrictions, limitations, or requirements set forth on Schedule 8.1(d).

With respect to Losses incurred in connection with or arising out of any Remediation requirement, the Sellers shall be obligated to indemnify and hold harmless the Purchaser Indemnified Parties only to the extent of the least cost remedy allowed under Environmental Laws applicable to the Sites and Facilities that is consistent with the ongoing use of the Sites and Facilities for chemical manufacturing purposes, such as (for example only) recording deed notices or restrictive covenants in lieu of performing soil or groundwater remediation.

(e) Unknown On-Site Environmental Contamination discovered by the Purchaser Indemnified Parties during any of the following activities shall constitute the sole exceptions to the limitations set forth in subsections 8.1(d)(2) and (3) above:

(i) The voluntary installation of perimeter monitoring wells near the outside boundaries of any of the Odessa Site, the Marysville Site or the Longview Owned Site in a manner consistent with subsection 8.1(f);

(ii) routine maintenance of existing facilities;

(iii) demolition of all or any portion of the existing facilities and related utilities down to ground surface (but not below ground surface unless necessary to properly isolate the underground structure from the operating portions of the facility) in a manner consistent with subsection 8.1(f);

(iv) construction of new facilities or modification of existing facilities (but not environmental sampling facilities other than the perimeter monitoring wells covered by subsection 8.1(e)(i)) in a manner consistent with subsection 8.1(f); and

(v) activities required by applicable Laws or by a Governmental Entity pursuant to Environmental Laws in effect at Closing.

(f) The exceptions set forth in subsections 8.1(e)(i), (iii) and (iv) above shall be effective only if the Purchaser Indemnified Parties satisfy the following conditions:

(i) the Purchaser shall provide written notice to the Sellers at least forty-five (45) days prior to initiation of any installation, demolition or construction activities;

(ii) the written notice shall specify in reasonable detail the nature and extent of the proposed activity and its location on the Site, with information sufficient to enable the Sellers reasonably to evaluate the extent and nature of the contemplated disturbance of the property;.

(iii) the Sellers shall have thirty (30) days in which to provide the Purchaser with comments and suggestions on the proposed activity;

(iv) the Purchaser shall take into account and, where commercially reasonable, accommodate the Sellers’ comments and suggestions regarding the project.

(g) Any Release of Hazardous Material, or other contamination or environmental condition, at, on, or under the Sites that is confirmed or discovered by the Purchaser within one (1) year after the Closing Date shall be presumed to be Unknown On-Site Environmental Contamination covered by the Sellers’ indemnification obligations in Section 8.1; provided, however, such presumption shall be a rebuttable presumption which may be challenged by the Sellers through the introduction of evidence of any post-Closing Releases of Hazardous Material or other post-Closing activities that may have caused or contributed to the Environmental Contamination. A Release of Hazardous Material or other contamination or environmental condition that is confirmed or discovered by the Purchaser more than one (1) year after the Closing Date also may be Unknown On-Site Environmental Contamination but there shall be no presumption and the burden of proof with respect to any such matter shall be established by applicable Law.

(h) To the extent there is an Environmental Rep Breach that results in Losses (other than Losses associated with Remediation) with respect to which the Sellers are obligated to indemnify and hold harmless the Purchaser Indemnified Parties pursuant to this Article VIII, the Purchaser shall have the right to manage and control any and all contact with any Governmental Entity arising out of such Environmental Rep Breach, and any such Purchaser Environmental Indemnity Claim shall not be subject to the limitations set forth in Sections 8.1(c) – (g); provided, however, the Sellers shall be obligated to indemnify and hold harmless the Purchaser Indemnified Parties only to the extent of the least cost remedy allowed under Environmental Laws applicable to the Sites and Facilities that is consistent with the ongoing use of the Sites and Facilities for industrial or chemical manufacturing purposes.

Section 8.2 Environmental Indemnification by the Purchaser.

(a) Subject to the provisions of this Article VIII, from and after the Closing Date the Purchaser shall indemnify and hold harmless the Seller Indemnified Parties from and against, and shall reimburse the Seller Indemnified Parties for all Losses that the Seller Indemnified Parties incur resulting from or arising out of (i) Remediation of any and all Known On-Site Environmental Contamination and all Known Off-Site Migrated Environmental Contamination, except to the extent that there is a Material Increase in Known On-Site Environmental Contamination, and (ii) Indemnifiable Assumed Liabilities or any Environmental Rep Breaches to the extent the Sellers are not liable for such matters based upon the limitations set forth in Section 8.6.

(b) In the event that a Seller Indemnified Party becomes aware of any claim, suit, action, litigation, arbitration, audit, hearing, investigation, inquiry or other proceeding by a Governmental Entity or other Person or other occurrence that may potentially result in indemnification pursuant to this Section 8.2 (a “Seller Environmental Indemnity Claim”), the Seller Indemnified Party shall, as soon as reasonably practicable after becoming aware of such occurrence, notify the Purchaser in writing of such Seller Environmental Indemnity Claim. The failure by any Seller to timely provide such notice shall not affect the right of the Sellers to indemnification pursuant to this Article VIII, except to the extent the Purchaser is prejudiced by such delay or omission.

(c) In the event that a Seller Indemnified Party makes a Seller Environmental Indemnity Claim for which it is entitled to indemnification pursuant to this Section 8.2, the Purchaser shall have the right, but not the obligation, to manage all matters arising out of, resulting from or relating to such Seller Environmental Indemnity Claim. To this end, the Purchaser shall, within thirty (30) days after the notice described in Section 8.2(b) has been given, notify the Sellers of its intent to manage such Seller Environmental Indemnity Claim. In the event the Purchaser exercises this management option and provides such notice to the Sellers, then the Purchaser shall manage such claim in accordance with the provisions of Section 8.1(h), and shall provide Meaningful Participation Rights to the Sellers at all times. In the event the Purchaser fails or refuses to exercise this management option and provide such notice to the Sellers, then the Sellers shall manage such claim in accordance with the provisions of Section 8.1(c), and shall provide Meaningful Participation Rights to the Purchaser at all times.

Section 8.3 Environmental Covenants of the Sellers.

(a) The Sellers will, and will cause their Affiliates to, (i) prepare complete and accurate notices and reports required under Environmental Laws and Environmental Permits with regard to the Assets and the Business to the extent such notices and reports relate to periods during which the Assets and the Business were owned or operated by the Sellers; (ii) provide copies of all such notices and reports to the Purchaser as soon as practical; (iii) sign and, if required by applicable Law, certify all such notices and reports, in each case after a reasonable inquiry with regard to the information contained in such notices and reports; and (iv) file all such notices and reports with the appropriate Governmental Entity or other third party no later than the date on which such reports or notices are required to be filed. The Sellers will use commercially reasonable efforts to complete all of the foregoing actions prior to the Closing Date, but if such actions are not required to be completed prior to the Closing Date, then the Sellers shall complete after the Closing Date any actions that are not required to be completed prior to the Closing Date and the Purchaser shall provide to the Sellers access to any records or other information reasonably requested to enable the Sellers to prepare such notices and reports.

(b) The Sellers will, between the date of this Agreement and Closing, prepare updated surveys for asbestos containing materials at each of the Facilities, and shall provide such updated surveys to the Purchaser on or prior to the Closing Date. The Sellers shall also cause the data described in Section 4.17(l) to be transferred to the Purchaser as of the Closing Date.

Section 8.4 Environmental Covenants of the Purchaser.

(a) The Purchaser shall perform Remediation of all Known On-Site Environmental Contamination and all Known Off-Site Migrated Environmental Contamination as may be required by Environmental Law.

(b) The Purchaser shall pay the costs associated with the Indemnifiable Assumed Liabilities and Environmental Rep Breaches to the extent such costs fall outside

the scope of the Sellers’ indemnity obligations for the Indemnifiable Assumed Liabilities and Environmental Rep Breaches based upon the limitations set forth in Section 8.6.

Section 8.5 Other Environmental Matters. Notwithstanding the limitations set forth in Section 6.2, the Purchaser and its agents and representatives shall have the right, during the period commencing on the date hereof through the Closing Date, to contact relevant Governmental Entities and discuss the environmental performance of and other environmental matters with regard to the Business and the Assets, as part of the Purchaser’s diligence activities. In connection with the foregoing, the Sellers shall be notified in advance of any such contacts by the Purchaser and shall be provided with an unrestricted right to participate in all such discussions with Governmental Entities unless either (i) the Sellers do not make themselves available for such discussions in a reasonably timely manner; or (ii) a Governmental Entity requests an ex parte meeting with the Purchaser.

Section 8.6 Limitations on Liability of the Sellers.

(a) Subject to Section 8.6(d) below, the Sellers shall have no liability under this Article VIII arising out of or relating to any Losses incurred by the Purchaser Indemnified Parties for any Indemnifiable Assumed Liabilities or any Environmental Rep Breaches except if the aggregate Losses incurred by the Purchaser Indemnified Parties hereunder with respect thereto exceed $15,000,000 (the “Environmental Deductible”) (and then, only to the extent such aggregate Losses exceed $15,000,000).

(b) Once the Purchaser Indemnified Parties have suffered total Losses for Indemnifiable Assumed Liabilities and Environmental Rep Breaches in excess of the amount specified in Section 8.6(a), the Sellers shall have no liability under this Article VIII arising out of or relating to any Indemnifiable Assumed Liability or any Environmental Rep Breach that results in Losses of less than $25,000.

(c) In no event shall the Sellers’ aggregate liability arising out of or relating to Losses for Indemnifiable Assumed Liabilities and Environmental Rep Breaches incurred by the Purchaser Indemnified Parties exceed $150,000,000 (the “Environmental Cap”).

(d) At the time that any Purchaser Indemnified Party makes any Purchaser Environmental Indemnity Claim that arises out of or is related to Losses incurred by the Purchaser Indemnified Parties for any Indemnifiable Assumed Liabilities or any Environmental Rep Breaches that may reasonably be expected to be covered by Novacor’s indemnification obligations under the Novacor Agreement, the Sellers agree that at the Purchaser’s sole cost and expense, the Sellers shall bring a claim for indemnification against Novacor with respect to such Purchaser Environmental Indemnity Claim and pursue such claim against Novacor in good faith. If the Sellers receive any proceeds from Novacor as a result of pursuing such claim, the Sellers shall deliver such proceeds to the Purchaser, and no Losses will be attributed to the Environmental Deductible to the extent of such proceeds. If the Sellers do not receive any proceeds from Novacor as a result of such claim, the Losses incurred by the Purchaser Indemnified Parties associated with such Purchaser Environmental Indemnity Claim shall apply to the Environmental Deductible.

(e) Any Losses incurred by the Purchaser Indemnified Parties related to Off-Site Disposal Activities shall be subject to the limitations set forth in Section 12.2(c) related to Other Retained Liabilities.

(f) The Sellers shall have no liability under this Article VIII resulting from or arising out of any Losses incurred by the Purchaser Indemnified Parties for any Indemnifiable Assumed Liabilities for which a Purchaser Environmental Indemnity Claim is made by any Purchaser Indemnified Party after the tenth (10th) anniversary of the Closing Date.

Section 8.7 Mitigation. Notwithstanding anything to the contrary herein, the Parties shall have a duty to use commercially reasonable efforts to mitigate any prospective or actual Losses arising out of or relating to this Agreement or the transactions contemplated hereby. In futherance, and not in limitation of the foregoing, the Purchaser agrees that whenever it brings a Purchaser Environmental Indemnity Claim with respect to Longview Environmental Contamination or Environmental Rep Breaches (with respect to remediation) against the Sellers, it will also bring a claim against Eastman Chemical Company pursuant to the Longview Lease and whenever it brings a Purchaser Environmental Indemnity Claim with respect to any Assumed Environmental Liabilities or any Environmental Rep Breaches (with respect to remediation) relating to the Port Arthur Site, it will also bring a claim against the Texaco Parties pursuant to the Assigned Indemnity.

(a) Subject to the provisions of this Article XII, from and after the Closing Date, the Sellers shall jointly and severally indemnify and hold harmless the Purchaser Indemnified Parties from and against any and all claims, liabilities, obligations, damages, losses, costs, expenses, penalties, fines and judgments (at equity or at law, including statutory and common) and damages whenever arising or incurred (including amounts paid in settlement, costs of investigation and reasonable attorneys’ fees and expenses) (collectively, “Losses”) that the Purchaser Indemnified Parties incur resulting from or arising out of (i) any breach of any representations and warranties of the Sellers in Article IV (except for breaches of the representations and warranties set forth in Section 4.17, which are subject to the terms of Article VIII), including any inaccuracy of any representation or warranty resulting from such representation or warranty being treated as if it were brought down and remade effective on and as of the Closing Date (except where such representation and warranty is specifically limited by its terms to a specified date, in which case such representation shall not be treated as having been so brought down and remade); (ii) any breach of any obligation of the Sellers in this Agreement (except for any breaches of any obligation of the Sellers set forth in Article VIII, which are addressed therein); or (iii) any Retained Liabilities (except for Longview Environmental Contamination, Peru Environmental Contamination and Off-Site Disposal Activities, which are subject to the terms of Article VIII).

(b) Subject to the provisions of this Article XII, from and after the Closing Date, the Purchaser shall indemnify and hold harmless the Seller Indemnified Parties from and against all Losses that the Seller Indemnified Parties incur resulting from or arising out of (i) any breach of any representations and warranties of the Purchaser in this Agreement, (ii) any breach of any obligation of the Purchaser in this Agreement, or (iii) the Purchaser’s ownership or operation of the Assets or the Business from and after the Closing Date or relating to the Assumed Liabilities, in each case to the extent such Losses do not result from or arise out of a matter to which the Purchaser is otherwise entitled to indemnification pursuant to Section 12.2(a) or Article VIII.

(c) Notwithstanding Section 12.2(a)(iii), the Purchaser shall pay to (or on behalf of) the Seller Indemnified Parties one hundred percent (100%) of the first Five Million Dollars ($5,000,000) of any Losses resulting from or arising out of any Other Retained Liabilities incurred by the Seller Indemnified Parties in each twelve month

period measured from the Closing Date (without carryover to any subsequent twelve month period), subject to the following:

(i) the Purchaser shall not pay or reimburse the Seller Indemnified Parties for Losses resulting from or arising out of Other Retained Liabilities (A) in an amount in excess of Fifty Million Dollars ($50,000,000) in the aggregate or (B) for which a claim is made by the Seller Indemnified Parties after the twentieth (20th) anniversary of the Closing Date;

(ii) in no event shall the Purchaser be required to pay or reimburse the Seller Indemnified Parties for any Losses resulting from or arising out of Other Retained Liabilities incurred by the Seller Indemnified Parties that are recovered by the Seller Indemnified Parties from either Novacor pursuant to Novacor’s indemnification obligations under the Novacor Agreement or the Texaco Parties pursuant to the Texaco Parties’ indemnification obligations under the Texaco Agreement;

(iii) in no event shall the Purchaser be required to pay or reimburse the Seller Indemnified Parties for any Losses resulting from or arising out of any Other Retained Liabilities that result in Losses of less than $25,000; and

(iv) in no event shall the Purchaser be required to pay or reimburse the Seller Indemnified Parties for any Losses resulting from or arising out of a matter to which the Purchaser is entitled to indemnification pursuant to Section 12.2(f).

(d) For the purposes of determining when a claim is made by a Seller Indemnified Party for the Purchaser to pay or reimburse the Seller Indemnified Parties for Losses resulting from or arising out of any Other Retained Liabilities pursuant to Section 12.2(c) to which the mitigation requirements of Section 12.3(f) apply, the date on which the Purchaser receives a notice from a Seller Indemnified Party which states, if applicable, that the Seller Indemnified Parties are seeking to first recover such Losses from Novacor and/or the Texaco Parties as required pursuant to Section 12.3(f) shall be deemed to be the date on which such claim is made by the Sellers.

(e) For purposes of determining the amount of Losses suffered by a Party for breach of any representation and warranty, any qualifiers regarding “materiality,” “material adverse effect” or “Material Adverse Effect” contained in such representations and warranties shall be disregarded.

(f) The Sellers shall indemnify and hold harmless the Purchaser Indemnified Parties for all Losses resulting from or arising out of (i) any suit, action, claim or proceeding brought by any third party based upon the arrangements set forth in Section 6.5(a)(v) or 6.5(b); or (ii) the items set forth on Schedule 12.2(f).

Section 12.3 Indemnification Procedures. Except as otherwise provided for under Article VIII, claims for indemnification under this Agreement shall be asserted and resolved as follows:

(a) Any Indemnified Party claiming indemnification under this Agreement with respect to any claim asserted against the Indemnified Party by a third party (“Third Party Claim”) in respect of any matter that is subject to indemnification under Section 12.2 (without regard to the limitations in Section 12.4(a) or (b), as applicable) shall promptly (i) notify the other Party (the “Indemnifying Party”) of the Third Party Claim and (ii) transmit to the Indemnifying Party a written notice (“Claim Notice”) describing in reasonable detail the nature of the Third Party Claim, a copy of all papers served with respect to such claim (if any), the Indemnified Party’s best estimate of the amount of Losses attributable to the Third Party Claim and the basis of the Indemnified Party’s request for indemnification under this Agreement. Failure to timely provide such Claim Notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is prejudiced by such delay or omission.

(b) The Indemnifying Party shall have the right to defend the Indemnified Party against a Third Party Claim, except when (i) a Third Party Claim is made by a Governmental Entity, in which case the Indemnified Party shall have the right to control such claim solely to the extent it pertains to such Indemnified Party or (ii) the Purchaser is the Indemnified Party and the amount of Losses attributable to the Third Party Claim is in excess of the Cap, in which case the Purchaser shall have the right to control such claim. If the Indemnifying Party notifies the Indemnified Party that the Indemnifying Party elects to assume the defense of the Third Party Claim, then the Indemnifying Party shall have the right to defend such Third Party Claim with counsel selected by the Indemnifying Party (who shall be reasonably satisfactory to the Indemnified Party), by all appropriate proceedings, to a final conclusion or settled at the discretion of the Indemnifying Party in accordance with this Section 12.3(b). The Indemnifying Party shall defend any such Third Party Claim in good faith and have full control of such defense and proceedings, including any compromise or settlement thereof; provided, that the Indemnifying Party shall not enter into any settlement agreement without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed); provided further, that such consent shall not be required if (a) the settlement agreement contains a complete and unconditional general release by the third party asserting the claim to all Indemnified Parties affected by the claim, (b) the settlement agreement does not contain any sanction or restriction upon the conduct of any business by the Indemnified Party or its Affiliates, and (c) the Indemnifying Party actually pays any and all amounts required pursuant to such settlement and is not disputing its indemnification obligation with respect to such claim. If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim which the Indemnifying Party elects to contest, including the making of any related counterclaim against the Person asserting the Third Party Claim or any cross complaint against any Person. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 12.3(b), and the Indemnified Party shall bear its own costs and expenses with respect to such participation. If in connection with any Third Party Claim related to any breach of a representation or warranty of the Sellers in this Agreement, which the Indemnifying Party has elected to assume the defense of, the third party making such claim offers a

settlement to the Indemnifying Party, the Indemnifying Party must notify the Indemnified Party of such settlement offer. If such settlement offer is less than or equal to the Cap and the Indemnified Party notifies the Indemnifying Party that it believes that it is advisable for the Indemnifying Party to accept such settlement offer, but the Indemnifying Party rejects such settlement offer and the Third Party Claim proceeds to a judgment, and such judgment exceeds the Cap, the Indemnifying Party shall be obligated to pay the entire amount of such judgment notwithstanding the fact that such amount exceeds the Cap. If such settlement offer is more than the Cap and the Indemnified Party notifies the Indemnifying Party that it believes that it is advisable for the Indemnifying Party to accept such settlement offer, but the Indemnifying Party rejects such settlement offer and the Third Party Claim proceeds to a judgment, and such judgment exceeds the settlement offer, the Indemnifying Party shall be obligated to pay the entire amount of such judgment less the amount which the Indemnified Party would have been required to pay had the settlement offer been accepted, notwithstanding the fact that such amount exceeds the Cap.

(c) If the Indemnifying Party fails to notify the Indemnified Party within 30 days after receipt of any Claim Notice that the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 12.3(b), or to the extent an Indemnified Party is controlling a claim pursuant to the parenthetical in the first sentence of Section 12.3(b), then the Indemnified Party shall defend any such Third Party Claim with counsel selected by the Indemnified Party, by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnified Party to a final conclusion or settled. In such circumstances, the Indemnified Party shall defend any such Third Party Claim in good faith and have full control of such defense and proceedings; provided however, that the Indemnified Party may not enter into any compromise or settlement of such Third Party Claim (except when a Third Party Claim is made by a Governmental Entity and solely to the extent it pertains to the Indemnified Party) if indemnification is to be sought hereunder, without the Indemnifying Party’s consent (which consent shall not be unreasonably withheld, conditioned or delayed). If requested by the Indemnified Party, the Indemnifying Party agrees, at its sole cost and expense, to cooperate with the Indemnified Party and its counsel in contesting any Third Party Claim which the Indemnified Party elects to contest. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 12.3(c), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation; provided, that if at any time the Indemnifying Party acknowledges in writing such Third Party Claim is a Loss subject to this Article XII, the Indemnifying Party shall be entitled to assume the defense of such Third Party Claim in accordance with Section 12.3(b) (except when a Third Party Claim is made by a Governmental Entity, in which case the Indemnified Party shall have the right to control such defense or settlement solely to the extent it pertains to such Indemnified Party).

(d) A claim for indemnification for any matter not involving a Third Party Claim may be asserted by notice to the Party from whom indemnification is sought.

(e) In the event an Indemnified Party shall recover Losses in respect of a claim of indemnification under this Article XII, no other Indemnified Party shall be entitled to recover the same Losses in respect of a claim for indemnification.

(f) Notwithstanding anything to the contrary herein, the Parties shall have a duty to use commercially reasonable efforts to mitigate any prospective or actual Losses arising out of or relating to this Agreement or the transactions contemplated hereby. In furtherance and not in limitation of the foregoing, the Sellers agree that whenever any Seller Indemnified Party seeks reimbursement from the Purchaser for any Other Retained Liability pursuant to Section 12.2(c), such Seller Indemnified Party will also bring, to the extent applicable, a claim against Novacor pursuant to the Novacor Agreement or the Texaco Parties pursuant to the Texaco Agreement as the case may be.

(g) The right to indemnification based on representations and warranties in this Agreement shall not be affected by any knowledge of the Indemnified Party that may have been acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of any such representation and warranty. The waiver of any condition based on the accuracy of any representation and warranty, or on the performance of or compliance with any covenant or agreement in this Agreement, will not affect any of the remedies set forth in clauses (i), (ii) and (iv) of the first sentence of Section 12.5(a) that may be available.

Section 12.4 Limitations on Liability of the Sellers.

(a) The Sellers shall have no liability arising out of or relating to any Losses incurred by the Purchaser Indemnified Parties resulting from any breach of a representation or warranty of the Sellers in this Agreement (other than breaches of the representations and warranties of the Sellers in Sections 4.1, 4.2, 4.12, 4.17 (which shall be subject to the Environmental Deductible pursuant to Section 8.6(a)) and 4.20, which shall not be subject to the limitation on liability contained in this Section 12.4(a)) except if the aggregate Losses incurred by the Purchaser Indemnified Parties hereunder exceed $10,000,000 (and then, only to the extent such aggregate Losses exceed $10,000,000).

(b) Once the Purchaser has suffered total Losses in excess of the amount specified in Section 12.4(a), a breach of representation and warranty that results in Losses of less than $25,000 shall be deemed not to be a breach of such representation and warranty.

(c) Except as otherwise provided in Section 12.3(b), in no event shall the Sellers’ aggregate liability arising out of or relating to Losses incurred by the Purchaser Indemnified Parties and resulting from any breach of a representation or warranty of the Sellers in this Agreement (other than breaches of the representations and warranties of the Sellers in Sections 4.1, 4.2, 4.12, 4.17 (which shall be subject to the Environmental Cap pursuant to Section 8.6(c)) and 4.20 of this Agreement, which shall not be subject to the limitation on liability contained in this Section 12.4(c)) exceed $150,000,000 (the “Cap”).

(d) The Purchaser shall not be entitled to seek indemnification pursuant to any provision of this Agreement as a result of any payments required to be made by the Purchaser pursuant to Section 12.2(c).

Section 12.5 Waiver of Remedies.

(a) From and after the Closing, notwithstanding anything to the contrary herein, the Parties hereby agree that, except for (i) the indemnity obligations expressly provided in Sections 6.2, 6.5(b), 6.16(c), 12.2 and Article VIII (the “Indemnity Obligations”), (ii) the reimbursement obligations expressly provided in Sections 6.4(b), 6.4(d), 6.5(a), 6.7(d), 6.10(b), 6.11, 6.12, 6.14(b) and 6.21 (the “Reimbursement Obligations”), (iii) the rights and obligations of the Parties relating to the Ancillary Documents and (iv) any claims based on fraud, no Party shall have any liability, and no Party shall make any claim, for any Losses or other matter, under, arising out of or relating to this Agreement, any other document, agreement, certificate or other matter delivered pursuant hereto or the transactions contemplated hereby whether based on contract, tort, strict liability, other Laws or otherwise. The Parties acknowledge and agree that the remedies set forth in clauses (i), (ii) and (iv) of the previous sentence are the sole and exclusive remedies of the Parties for any breaches of this Agreement from and after the Closing.

(b) Notwithstanding anything to the contrary in this Agreement, except for (i) the Indemnity Obligations, (ii) claims made under the Reimbursement Obligations, (iii) the rights and obligations of the Parties relating to the Ancillary Documents, (iv) any claims based on fraud, and (v) any claims against a Party not related to this Agreement or the transactions contemplated hereby, the Purchaser on behalf of the Purchaser Indemnified Parties and the Sellers on behalf of the Seller Indemnified Parties shall be deemed to have waived, to the fullest extent permitted under applicable Law, any right of contribution against the Sellers or the Purchaser, or any of their Affiliates, as the case may be, and any and all rights, claims and causes of action it may have against the Sellers or any of their Affiliates or the Purchaser or its Affiliates, as the case may be, arising under or based on any Law or otherwise.

(c) NOTWITHSTANDING ANYTHING IN THIS AGREEMENT TO THE CONTRARY, (1) EXCEPT FOR CLAIMS BASED ON FRAUD OR SECTION 12.2(f)(ii), NO PARTY SHALL BE LIABLE TO ANY OTHER PARTY UNDER THIS AGREEMENT FOR SPECIAL, CONSEQUENTIAL OR INDIRECT DAMAGES OR LOST REVENUES OR LOST PROFITS, AND (2) EXCEPT FOR CLAIMS BASED ON FRAUD, NO PARTY SHALL BE LIABLE TO ANY OTHER PARTY UNDER THIS AGREEMENT FOR PUNITIVE, EXEMPLARY OR INCIDENTAL DAMAGES, IN EACH CASE WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM THE OTHER PARTY’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT, AND IN EACH CASE UNLESS SUCH PARTY IS THE INDEMNIFYING PARTY HEREUNDER AND SUCH DAMAGES ARE PAYABLE BY AN INDEMNIFIED PARTY PURSUANT TO A THIRD PARTY CLAIM.

Section 12.6 Treatment of Payments. Any payments made pursuant to Article VIII or this Article XII shall be treated by the Parties as an adjustment to the Purchase Price.

Section 12.7 No Other Representations. NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, IT IS THE EXPLICIT INTENT OF EACH PARTY HERETO, AND THE PARTIES HEREBY AGREE, THAT NONE OF THE SELLERS, THE PURCHASER OR ANY OF THEIR RESPECTIVE AFFILIATES OR REPRESENTATIVES HAS MADE OR IS MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, WRITTEN OR ORAL, WITH RESPECT TO THE TRANSACTIONS, EXCEPT THOSE REPRESENTATIONS AND WARRANTIES EXPRESSLY CONTAINED IN THIS AGREEMENT.

Section 12.8 Assumption of Mansonville Business Transition Risk. The Purchaser acknowledges that it is not acquiring the Mansonville Site and intends to transition the manufacturing business currently conducted at the Mansonville Site (including any related sales or marketing of product) (the “Existing Mansonville Business”) to the Peru Site (the “Mansonville Business Transition”) on or before the end of the EPS Exchange and Licensing Agreement to be entered into at the Closing (the “EPS Exchange and Licensing Agreement”), and agrees, subject to the Sellers’ (a) compliance with the EPS Exchange and Licensing Agreement; (b) compliance with their obligations under Sections 2.1, 6.4 and 9.2(j) with respect to the Assets of the Existing Mansonville Business being conveyed under this Agreement; and (c) conduct of the Existing Mansonville Business during the period from the date hereof through the Closing Date in a manner that complies with Section 6.1, but only to the extent such compliance is necessary for and consistent with the performance by the Sellers of their obligations under the EPS Exchange and Licensing Agreement, that (i) for purposes of determining whether a Material Adverse Effect has occurred, any adverse change, event, effect, circumstance or occurrence on (A) the Existing Mansonville Business resulting from the announcement of this Agreement or the Mansonville Business Transition, (B) the likelihood of successful implementation of the Mansonville Business Transition or (C) the contracts or customer relationships associated with the Existing Mansonville Business (the matters described in clauses (A), (B) and (C) above being referred to as the “Mansonville Transition Risks”) shall be disregarded; and (ii) the Purchaser waives any claim it might otherwise have under this Agreement based upon or arising out of the Mansonville Transition Risk. Notwithstanding the foregoing, nothing in this Section 12.8 shall create any liability of the Purchaser or any of its Affiliates to the Sellers for any liabilities or obligations incurred by the Sellers resulting out of or related to the Mansonville Facility or the Mansonville Site after the EPS Exchange and Licensing Agreement has terminated or otherwise expired.

Section 13.2 Schedules and Exhibits. The Schedules and Exhibits hereto are hereby incorporated into this Agreement and are hereby made a part hereof as if set out in full herein.

Section 13.3 Assignment; Successors in Interest.

(a) Except as provided in this Section 13.3, no assignment or transfer by any Party of such Party’s rights and obligations hereunder shall be made without the prior written consent of the other Parties.

(b) The Purchaser may, without the obligation to obtain the prior written consent of the Sellers, but with the obligation to provide contemporaneous or prior notice to the Sellers, assign this Agreement or all or any part of its rights or obligations hereunder to one or more Persons, provided, that any assignment under this Section 13.3(b) (whether by the Purchaser or any Qualified Transferee) shall be permitted only to a Person in which the Purchaser or Koch Industries, Inc. owns, directly or indirectly, 50% or more of such Person’s outstanding equity interests (a “Qualified Transferee”); and the Purchaser (or any such Qualified Transferee, if applicable) may pledge, assign and grant to the Purchaser’s (or such Qualified Transferee’s) lenders, for the benefit of such lenders, a continuing security interest on all of the Purchaser’s or Qualified Transferee’s right, title and interest in and to this Agreement and any and all related agreements, as security for the payment and performance of all obligations of the Purchaser or such Qualified Transferee to such lenders by reason of borrowings or the guarantee of borrowings, or otherwise; provided, however, that any foreclosure or assignment in lieu thereof by any such lenders shall be subject to the restrictions on assignment or transfer set forth herein. No such assignment to a Qualified Transferee or pledge, grant or assignment of a security interest shall release or discharge the Purchaser from any of its obligations as the “Purchaser” under this Agreement or the Purchaser Ancillary Documents and the transactions contemplated by this Agreement or any Purchaser Ancillary Documents (including from the obligations the Purchaser otherwise would have had under any such Ancillary Document if the Purchaser had not assigned the obligation to enter into any such Ancillary Document to a Qualified Transferee), and any such Qualified Transferee shall, as a condition to assignment hereunder, expressly agree to be subject to the terms set forth in this Section 13.3 and assume the obligations set forth in Section 8.1(d)(8) (with respect to the Assets received by such Qualified Transferee).

(c) The Sellers may, without the obligation to obtain the prior written consent of the Purchaser, but with the obligation to provide contemporaneous or prior notice to the Purchaser, assign this Agreement or all or any part of the Business or Assets, or the Sellers’ rights or obligations hereunder to one or more Persons. No such assignment to a Person shall release or discharge the Sellers from any of their obligations as the “Sellers” under this Agreement or the Seller Ancillary Documents and the transactions contemplated by this Agreement or any Seller Ancillary Documents. For the avoidance of doubt, the Sellers may convey any of the Excluded Assets without any notice to or consent of the Purchaser, except as may otherwise be required under any applicable Commercial Agreement.

(d) Subject to Section 13.3(e) below, the Purchaser (or a Qualified Transferee) shall have the right to assign its rights of indemnification pursuant to Article VIII and Article XII to one or more subsequent owners of all or any portion of the Assets, subject to (i) the approval of the Sellers, which approval shall not be unreasonably withheld, conditioned or delayed and (ii) the requirement that, as a condition to assignment hereunder, such assignee expressly agrees to be subject to the terms set forth in this

Section 13.3 and assumes the obligations set forth in Section 8.1(d)(8) (with respect to the Assets received by such assignee); provided, however, that for purposes of this Section 13.3, any Change of Control of the Purchaser or a Qualified Transferee shall be deemed an assignment pursuant to this Section 13.3(d) of the rights to indemnification with respect to the Assets owned by the Purchaser or such Qualified Transferee at the time of such Change of Control; provided, however, that any change in the ownership of Koch Industries, Inc. shall not be considered a Change of Control of the Purchaser or any Qualified Transferee.

(e) Once the Purchaser (or a Qualified Transferee) has assigned its rights of indemnification with respect to all or any portion of an Asset pursuant to Section 13.3(d), but not Section 13.3(b), the subsequent beneficiary of such indemnity shall have no further right to assign such indemnity again without the prior written consent of the Sellers, which the Sellers may withhold in their sole discretion. Further, if there is a Change of Control of the subsequent beneficiary without such prior written consent, the indemnification rights assigned to such subsequent beneficiary shall thereafter cease to be enforceable by such subsequent beneficiary, but such subsequent beneficiary shall continue to be bound by the obligations set forth in Section 8.1(d)(8) (with respect to the Assets received by such subsequent beneficiary).

(f) This Agreement shall be binding upon and shall inure to the benefit of the Parties and their respective successors and permitted assigns, and any reference to a Party shall also be a reference to the successors and permitted assigns thereof.

Section 13.4 Captions. The titles, captions and table of contents contained herein are inserted herein only as a matter of convenience and for reference and in no way define, limit, extend or describe the scope of this Agreement or the intent of any provision hereof.

Section 13.5 Controlling Law. This Agreement shall be governed by and construed and enforced in accordance with the internal Laws of the State of Texas without reference to its choice of law rules.

Section 13.6 Consent to Jurisdiction, Etc.; Waiver of Jury Trial. Each Party hereby irrevocably agrees that any Legal Dispute shall be brought only to the exclusive jurisdiction of the courts of the State of Texas in Harris County, Texas or the federal courts located in the Southern District of Texas, and each Party hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and except for the right of removal to a federal court located in the Southern District of Texas, irrevocably waives, to the fullest extent permitted by Law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that they any such suit, action or proceeding that is brought in any such court has been brought in an inconvenient forum. During the period a Legal Dispute that is filed in accordance with this Section 13.6 is pending before a court, all actions, suits or proceedings with respect to such Legal Dispute or any other Legal Dispute, including any counterclaim, cross-claim or interpleader, shall be subject to the exclusive jurisdiction of such court. Each Party hereby waives, and shall not assert as a defense in any Legal Dispute, that (a) such Party is not subject thereto, (b) such action, suit or proceeding may not be brought or is not maintainable in such

court, (c) such Party’s property is exempt or immune from execution, (d) such action, suit or proceeding is brought in an inconvenient forum or (e) the venue of such action, suit or proceeding is improper. A final judgment in any action, suit or proceeding described in this Section 13.6 following the expiration of any period permitted for appeal and subject to any stay during appeal shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Laws. THE PARTIES HEREBY WAIVE IRREVOCABLY ANY AND ALL RIGHTS TO DEMAND A TRIAL BY JURY IN CONNECTION WITH ANY LEGAL DISPUTE.

Section 13.7 Severability. Any provision hereof that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by Law, each Party hereby waives any provision of Law that renders any such provision prohibited or unenforceable in any respect. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the Parties agree that the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration, or area of the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified after the expiration of the time within which the judgment may be appealed.

Section 13.8 Counterparts. This Agreement may be executed in two or more counterparts, no one of which need be executed by all Parties but all of which shall constitute but one and the same contract, and each of which shall be deemed an original. It shall not be necessary in making proof of this Agreement or the terms hereof to produce or account for more than one of such counterparts.

Section 13.9 No Third-Party Beneficiaries. Except to the extent specified in Article VIII and Article XII, which are also intended to benefit and to be enforceable by any Indemnified Party, the rights, duties, and obligations under this Agreement are for the sole benefit of the Parties and their respective successors and permitted assigns, and are for the benefit of no other Person or Persons, and no rights will accrue to or arise for any other Person or Persons as a result of the express or implied terms, conditions, rights, duties, or obligations of, or set forth in, this Agreement. The obligations of the Sellers set forth in this Agreement are joint and several and the Sellers agree to be jointly and severally liable for the respective obligations of one another set forth in this Agreement, and HI agrees to be jointly and severally liable for any obligations of any Seller or any Affiliate of any Seller set forth in any Ancillary Agreement.

Section 13.10 Amendment; Waivers; Extensions. No amendment, modification, waiver, replacement, termination or cancellation of any provision of this Agreement will be valid, unless the same is in writing and signed by the Parties. Each waiver of a right hereunder does not extend beyond the specific event or circumstance giving rise to the right. No waiver by any Party of any default, misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default,

misrepresentation or breach of warranty or covenant hereunder or affect in any way any rights arising because of any prior or subsequent such occurrence. Neither the failure nor any delay on the part of any Party to exercise any right or remedy under this Agreement will operate as a waiver thereof, nor does any single or partial exercise of any right or remedy preclude any other or further exercise of the same or of any other right or remedy.

Section 13.11 Integration. This Agreement and the documents executed pursuant hereto supersede all negotiations, agreements and understandings among the Parties with respect to the subject matter hereof (except for the Confidentiality Agreement), and constitute the entire agreement among the Parties with respect thereto.

Section 13.12 Transaction Costs. Except as provided for in Sections 6.4(b), 6.4(d), 6.5(a), 6.5(b), 6.10(b) and Articles VII, VIII and XII, (a) the Purchaser shall pay its own fees, costs and expenses incurred in connection herewith and the transactions contemplated hereby, including the fees, costs and expenses of its financial advisors, environmental consultants, accountants and counsel, and (b) the Sellers shall pay their own fees, costs and expenses incurred in connection herewith and the transactions contemplated hereby, including the fees, costs and expenses of their financial advisors, accountants and counsel.
