Section 6.7 Consents.

(a) On the Closing Date, the Sellers shall assign to the Purchaser, and the Purchaser shall assume, the Assumed Contracts, the Existing Easements and the Licenses (including to the extent assignable the Environmental Permits and any pending applications for any Licenses or Environmental Permits) which are to be transferred to the Purchaser as provided in this Agreement by means of conveyance instruments in forms to be agreed. To the extent that the assignment of all or any portion of any Assumed Contract, Existing Easement or License (including any Environmental Permit or any pending application for any License or Environmental Permit) shall require the consent of the other party thereto or any other third party (including any Governmental Entity), this Agreement shall not constitute an agreement to assign any such Assumed Contract, Existing Easement or License if an attempted assignment without any such consent would constitute a breach or violation thereof; provided, however, that, if any such consent is required from any of the Sellers or any of their Affiliates, the Sellers agree to, and to cause their respective Affiliates to, consent to the assignment to the Purchaser of any such Assumed Contract, Existing Easement or License; provided further, however, that, with respect to any of the Easement Facilities (i.e., any pipeline or other facility considered in its entirety), 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 Closing such Easement Facility as well as the related Existing Easements. In such case, the Parties agree that on and after the Closing, they will use commercially reasonable efforts to do or

cause to be done all such things as shall be necessary and proper (i) with respect to the Assumed Contracts and Licenses not assigned at Closing (A) to assure that the rights of the Sellers under such Assumed Contracts and Licenses (including any Environmental Permits and any pending applications for any Licenses or Environmental Permits) shall be preserved for the benefit of the Purchaser (including any extension or renewal of any such Assumed Contracts or Licenses) and (B) to facilitate receipt of the consideration to be received by the Sellers in and under every such Assumed Contract and License (including any Environmental Permit and any pending application for any License or Environmental Permit), which consideration shall be held for the benefit of, and shall be delivered to, the Purchaser and (ii) with respect to each Easement Facility not conveyed at Closing, the Parties shall enter into a transportation agreement pursuant to which the Purchaser shall have all capacity rights (subject to the terms of any applicable Commercial Agreements) 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 Sellers against all such costs and risks. The Purchaser shall make all filings necessary to be named the operator of all the Easement Facilities (including with the Texas Railroad Commission) and to obtain and hold all Licenses relating to the Easement Facilities. The Parties shall share (50% by the Purchaser and 50% by the Sellers) the reasonable out-of-pocket costs of any title or related work required to obtain such consents. The Parties shall cooperate to seek and obtain all relevant consents as soon as practicable. Such transportation agreement shall be for nominal consideration, and when the 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 transportation agreement with respect to such Easement Facility and such Existing Easements shall terminate. Additionally, either Party may terminate such transportation agreement by giving two years notice, which notice may be given at any time on or after June 30, 2014. At the time of termination of the transportation agreement, the Sellers shall 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. With respect to any such Assumed Contract or License as to which the necessary approval or consent for the assignment or transfer to the Purchaser is obtained following the Closing, the Sellers shall transfer such Assumed Contract or License to the Purchaser by execution and delivery of an instrument of conveyance reasonably satisfactory to the Purchaser and the Sellers within ten days following receipt of such approval or consent.

(b) To the extent that the Licenses (including any Environmental Permits and any pending applications for any Licenses or Environmental Permits) necessary for the Purchaser’s operation of the Business as conducted as of the Closing Date have not been transferred to the Purchaser or otherwise obtained by the Purchaser as of the Closing, the Sellers shall allow, to the extent authorized by the terms of such Licenses (including any Environmental Permits and any pending applications for any Licenses or Environmental

Permits) and all Environmental Laws and other applicable Laws, the Purchaser to conduct the Business pursuant to the Sellers’ existing Licenses (including any Environmental Permits and any pending applications for any Licenses or Environmental Permits). Regarding each such License (including any Environmental Permit and any pending application for any License or Environmental Permit), the Sellers shall allow such use until the Purchaser obtains an equivalent License; provided, however, the Purchaser shall use commercially reasonable efforts to expeditiously obtain such equivalent License.

Section 6.8 Public Announcements. The Parties will consult with each other prior to any publication or press release of any nature with respect to this Agreement or the transactions contemplated hereby and shall not make or issue, or cause to be made or issued, any such publication or press release prior to such consultation and without the prior written consent of the other Parties hereto (which consent will not be unreasonably withheld or delayed) except to the extent, but only to such extent, that, in the opinion of the Party issuing such publication or press release, such announcement or statement may be required by Law, any order or regulation of a court or tribunal or Governmental Entity, any listing agreement with any securities exchange or any securities exchange regulation, in which case the Party proposing to issue such publication or press release shall make commercially reasonable efforts to (a) consult in good faith with the other Parties before issuing any such publication or press release and (b) provide a copy thereof to the other Parties prior to such issuance.

Section 6.9 Sellers’ Disclosure Schedules.

(a) From time to time up to the Closing, the Sellers shall promptly supplement or amend the Schedules that they have delivered with respect to any matter first existing or occurring following the date hereof that comes to the Sellers’ Knowledge or of which the Purchaser notifies the Sellers in writing and that (i) if existing or occurring at or prior to the date hereof, would have been required to be set forth or described in the Schedules, or (ii) is necessary to correct any information in the Schedules that has been rendered inaccurate thereby. Within five Business Days from receipt of notice of such supplement or amendment, the Purchaser shall notify the Sellers whether the Purchaser intends to pursue any or all of the remedies that may be available to the Purchaser for breach of the representation or warranty that relates to the Schedule that has been supplemented or amended. If the Purchaser notifies the Sellers that it intends to pursue any or all remedies that may be available to the Purchaser in accordance with the preceding sentence, such supplement or amendment shall have no effect for the purpose of determining satisfaction of the conditions set forth in Section 7.2 or the obligations of the Sellers under Section 10.1, and if the Purchaser does not notify the Sellers that is intends to pursue any or all of the remedies that may be available to the Purchaser in accordance with the preceding sentence, (i) the Purchaser shall be deemed to waive any and all such remedies arising from a breach of the relevant representation or warranty to the extent relating to such supplement or amendment, (ii) the relevant Schedule shall be deemed updated as supplemented or amended and (iii) the Schedule, as supplemented or amended, shall be used in determining whether the conditions set forth in Section 7.2 have been satisfied and whether the Sellers have any obligations under Section 10.1.

(b) The disclosure of any liability or obligation in the Schedules shall not create an Assumed Liability except to the extent that the disclosure of such liability or obligation has been expressly assumed by the Purchaser as an Assumed Liability as

provided in Section 2.3 of this Agreement.

(c) Any information, item or other disclosure set forth in any Schedule shall be deemed to have been set forth in any other Schedule, if the relevance of such disclosure to such other portion is readily apparent from the facts specified in such disclosure.

Contingent upon the full cooperation and compliance in the execution and delivery of all forms and authorizations that are part of the Purchaser’s hiring process, the Purchaser will offer employment to each Business Employee, except as provided in Sections 6.10(a)(i) and (ii).

(ii) The Purchaser shall not be required to offer employment to Business Employees who, between the date hereof and the Closing Date, begin to receive long-term disability benefits pursuant to a Seller Benefit Plan from either Seller or any of their Affiliates, except for any Business Employee who, at the time they began to receive such long-term disability benefits from either Seller or any of their Affiliates, was represented by any of the following unions under any of the CBAs with the Sellers: the Technical Control Union (the “TCU”), the United Brotherhood of Boilermakers, Iron Shipbuilders, Blacksmiths Forgers and Helpers (the “Boilermakers”), or the United Brotherhood of Carpenters and Joiners of America Carpenters (the “Carpenters”). For any Business Employee who (A) at the time he or she began to receive such long-term disability benefits from either Seller or any of their Affiliates, was represented by the TCU, the Boilermakers or xxx Xxxxxxxxxx under any of the CBAs with the Sellers, and (B) receives a medical release to return to work satisfactory to the Purchaser which, in the Purchaser’s reasonable discretion, substantiates the ability of such Business Employee to perform the functions of such Business Employee’s job immediately before the event that gave rise to the receipt of such long term disability benefits from either Seller or any of their Affiliates, within 12 months of the date on which such Business Employee began to receive such long-term disability benefits from either Seller or any of their Affiliates, the Purchaser shall offer employment to such Business Employee, subject to the same terms and conditions provided to the Transferred Employees, so long as such Business

Employee fully cooperates and complies in the execution and delivery of all forms and authorizations that are part of the Purchaser’s hiring process.

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. 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 purposes hereof, each of “qualified beneficiary”, “group health plan” and “qualifying event” shall have the meaning ascribed thereto in Section 4980B of the Code.

The Sellers shall assist the Purchaser in connection with its hiring process with respect to the Business Employees, including to the extent permitted by law by the provision of 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 all reasonable efforts to facilitate communication after the date hereof between the Purchaser and representatives of Union Employees including, without limitation, face-to-face meetings.

Section 6.11 Labor Matters.

(a) On or before the Closing Date, each Seller shall provide the Purchaser with a schedule of all layoffs and any other “employment losses” (as that term is defined in WARN) at each site that is the subject of the Business, by site of employment, implemented by such Seller during the 90-day period preceding the Closing.

(b) The Purchaser acknowledges that one or more of the Sellers is party to the CBAs. From and after the Closing Date, the Purchaser will concede a bargaining obligation to any labor organization representing a majority of hourly employees in an appropriate unit, and will comply with the terms of the applicable CBAs.

(c) The Sellers may continue with the JCO RIF; provided, however, the Sellers will keep the Purchaser informed on a timely basis of the progress thereof in such detail as the Purchaser may reasonably request. For those Business Employees who have already applied to participate in the JCO RIF and have (i) requested a resignation date that occurs after the Closing Date or (ii) indicated a range of acceptable resignation dates, which range extends beyond the Closing Date, the Sellers will use reasonable commercial efforts to secure agreement from those Business Employees or their representatives that, as a condition precedent to the Sellers’ acceptance of their applications to participate in the JCO RIF, their resignations would have to occur prior to the Closing Date. Notwithstanding the foregoing, the Sellers shall not make any commitments to terminate any Business Employees where the termination date would occur after the Closing Date.

Section 6.12 Transfer Taxes; Expenses.

Notwithstanding the foregoing, the Purchaser will bear all fees and expenses associated with its financing described in the Financing Commitment, including without limitation fees and expenses in connection with the preparation and filing of deeds of trust and other security instruments creating Liens for the benefit of its lenders.

Section 6.13 Risk of Loss. The risk of loss with respect to the Assets shall remain with the Sellers until the Closing, at which time such risk shall pass to the Purchaser. In the event prior to the Closing any Asset is lost, damaged or destroyed, if such loss, damage or destruction (a) is in excess of $5,000,000 and is either uninsured or within policy deductible or self-retention levels (and the Sellers shall not agree to be responsible for the amount of such loss, damage or destruction that exceeds $5,000,000), or (b) would likely result in a Material Adverse Effect, the Purchaser may terminate this Agreement in accordance with the provisions of Section 9.1(e). Otherwise, the Closing shall proceed and the Sellers shall assign to the Purchaser the proceeds of any insurance in respect of any such loss, damage or destruction.

Section 6.14 [Reserved]

Section 6.15 Collection of Receivables. Upon Closing, each of the Sellers shall, by letter prepared by the Purchaser and reasonably satisfactory to each of the Sellers (the “Letter”), irrevocably authorize, instruct and direct that the account parties of all Receivables (such parties,

the “Seller Account Parties”) make and deliver all payments relating thereto on or after the Closing Date to such location, bank and account (the “Lockbox Account”) as the Purchaser shall specify. If, notwithstanding such Letter, any of the Seller Account Parties remits any such payments on or after the Closing Date directly or indirectly to any of the Sellers instead of to the Lockbox Account, each Seller agrees that it shall promptly (and in any event no later than 15 days following receipt) deliver all such payments that it receives to the Purchaser. Effective upon the Closing, each of the Sellers hereby authorize the Purchaser (and all Persons designated by the Purchaser) to endorse for deposit, collection or negotiation to the Purchaser’s lenders checks or other payments forms (including negotiable and non-negotiable instruments) and proceeds received by the Purchaser via the Lockbox Account or from either Seller that relate to such Receivables. Each of the Sellers shall use its commercially reasonable efforts, at the Purchaser’s request, to assist the Purchaser in collecting in full from the Seller Account Parties all amounts owed pursuant to such Receivables. If, after Closing, a Seller Account Party is an additional 90 days delinquent in paying the Purchaser amounts owed with respect to a Receivable acquired by the Purchaser pursuant to this Agreement that was already 90 days delinquent at the time of the Closing (the “Delinquent Amount”), then the Sellers shall promptly (but in no event later than ten days after written request) pay the Purchaser an amount equal to the Delinquent Amount; provided, however, that concurrently with the payment of such amount to the Purchaser, the Purchaser shall (without recourse or warranty, except as to matters arising by, through or under it) reassign to the Sellers the related Receivable. The Purchaser shall use its commercially reasonable efforts, at a Seller’s request, to assist the Sellers in collecting amounts owing under accounts receivables that are the subject of clause (z) of the definition of Net Working Capital or that are reconveyed to a Seller pursuant to this Section 6.15.

Section 6.16 Key Customer and Key Supplier Visits. 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 with any Key Customer or Key Supplier that is listed on Schedule 6.16. Without the prior written 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 without limitation 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 meetings or discussions with any Key Customer or Key Supplier in respect of the Business shall not be a condition precedent to its obligations to close the transactions hereunder.

Section 6.17 Real Property Matters.

(a) The Sellers shall provide to the Purchaser copies of the title commitment, title policies and surveys listed on Schedule 6.17(a) (the “Existing Title Information”) relating to the Real Property, and shall reasonably cooperate with the Purchaser to the extent the Purchaser seeks to obtain for its and its lenders benefit TLTA title policies (“Purchaser Title Policies”) or surveys (“Surveys”) with respect to the Site, the

Combined Dock Real Property Interests and the JWWTP Conveyed Real Property Interest. The Purchaser shall bear the cost of any Purchaser Title Policies.

Such costs shall be borne 50% by the Purchaser and 50% by the Sellers.

(c) With respect to the Land Farm Site, the Parties shall use good faith efforts to finalize prior to Closing an ownership agreement that provides for an allocation of costs in accordance with the JWWTP Agreements and provides for a waiver of rights of partition, accounting and other similar rights inherent in a tenancy-in-common ownership arrangement.

Section 6.18 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 or otherwise be of interest to the Sellers and that the Parties should be provided access to such information.

(b) 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

Section 6.19 Litigation Support. In the event and for so long as any Party or any Affiliate thereof actively is contesting or defending any action, suit, grievance, proceeding, hearing, investigation, charge, complaint, claim or demand by a third party 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 Closing (or after Closing, if the Sellers are implicated) relating to or involving the Business, the Assets, the Business Employees, the Assumed Liabilities or the Retained Liabilities, 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 fair and 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 6.19 is in addition to, and does not in any way limit, the rights or obligations of any Party pursuant to Article X of this Agreement.

Section 6.20 Use of Names and Trademarks; Know-How. Following the Closing, neither the Purchaser nor any of its Affiliates shall, directly or indirectly, use or otherwise exploit the Huntsman name or any derivation thereof that would reasonably be expected to be confused therewith (the “Huntsman Name”), or any other tradenames, domain name, trademark or service xxxx confusingly similar thereto. Notwithstanding the foregoing, for a period of three (3) months following the Closing Date, the Purchaser and its Affiliates may, and the Sellers hereby grant to the Purchaser a non-exclusive non-transferable, royalty-free, irrevocable license to use, solely in connection with the operation of the Business, (a) pre-printed marketing materials, packaging materials, stationary, printed forms (other than MSDSs or similar documents) and office and shipping supplies on hand on the Closing Date containing the Huntsman Name thereon and (b) the Huntsman Name to the extent on any signs at the Facilities (other than the JWWTP) or other labels on any tanks, pipelines, railcars, vehicles or other equipment, assets or properties included in the Assets.

(a) any breach or inaccuracy of any representation or warranty made by either Seller in this Agreement or in any conveyance document to be executed by one or both of the Sellers in connection herewith, other than any representation or warranty contained in the second sentence of Section 4.4(a), the second sentence of Section 4.4(d) and the third sentence of Section 4.5(a);

(g) any Seller Benefit Plan, any ERISA Affiliate Plan or the employment of any employee or former employee by either Seller at any time.

The claims, liabilities, obligations, losses, damages, costs, expenses, penalties, fines and judgments of the Purchaser Indemnified Parties described in this Section 10.1 as to which the Purchaser Indemnified Parties are entitled to indemnification are collectively referred to as “Purchaser Losses.”

(a) any breach or inaccuracy of any representation or warranty made by the Purchaser in this Agreement;

Section 10.3 Indemnification Procedure.

(a) Promptly following receipt by an Indemnified Party of notice by a third party (including any Governmental Entity) of any complaint or the commencement of any audit, investigation, action or proceeding (in each case, a “Claim”) with respect to which such Indemnified Party may be entitled to receive payment from the other Party for any Purchaser Loss or any Seller Loss (as the case may be), such Indemnified Party shall notify the Purchaser or the Sellers, as the case may be (the “Indemnifying Party”), promptly following the Indemnified Party’s receipt of notice of such Claim; provided, however, that the failure to so notify the Indemnifying Party shall relieve the Indemnifying Party from liability hereunder with respect to such Claim only if, and only to the extent that, such failure to so notify the Indemnifying Party results in the loss by the Indemnifying Party of (or other limitations to) rights and defenses otherwise available to the Indemnifying Party or the Indemnified Party with respect to such Claim. The Indemnifying Party shall have the right, upon written notice delivered to the Indemnified Party within ten days thereafter, to assume the defense of such Claim (which may be with a reservation of rights to deny liability under an indemnity), including the employment of counsel hired in consultation with the Indemnified Party (“Litigation Counsel”) and the payment of the fees and disbursements of such Litigation Counsel and other costs of such defense. In the event, however, that the Indemnifying Party declines or fails to assume the defense of such Claim provided above or to employ Litigation Counsel, in either case within such ten-day period, then such Indemnified Party may employ counsel hired in connection with the Indemnifying Party to represent or defend the Indemnified Party in any such Claim, and the Indemnifying Party shall promptly reimburse the Indemnified Party for all reasonable fees and disbursements of such counsel and other reasonable costs of such defense (which reimbursement obligation shall accrue from the first dollar of such costs as incurred by the Indemnified Party, and which, for the avoidance of doubt, shall not be subject to the prior satisfaction of the Purchaser Deductible). In any event, the Indemnifying Party shall not be required to pay the fees and disbursements of more than one counsel for all Indemnified Parties in any jurisdiction in connection with such Claim, unless Litigation Counsel determines that continued representation of the Indemnified Party is inappropriate due to a conflict of interest under applicable ethical rules resulting from its representation of both the Indemnifying Party and such Indemnified Party, in which case, the Indemnifying Party shall have the option of (i) appointing substitute counsel that does not believe it is subject to such a conflict of interest or (ii) employing and paying the fees and disbursements of different counsel to represent such Indemnified Party. Notwithstanding the Indemnifying Party’s election to assume the defense of any third party Claim, the Indemnified Party shall have the right at its cost to employ separate counsel (including local counsel) to monitor (but not control) such defense. The Indemnifying Party or the Indemnified Party (as the case may be) shall at all times use commercially reasonable efforts to keep the Indemnifying Party or Indemnified Party (as the case may be) reasonably apprised of the status of the defense of any matter the defense of which it is maintaining and to cooperate in good faith with each other with respect to the defense of any such matter.

(b) No Indemnified Party may settle or compromise any Claim or consent to the entry of any judgment with respect to which indemnification is being sought

hereunder without the prior written consent of the Indemnifying Party, unless (i) the Indemnifying Party fails to assume and maintain the defense of such Claim pursuant to Section 10.3(a), (ii) such settlement, compromise or consent does not contain any admission or statement suggesting any wrongdoing or liability on behalf of the Indemnifying Party and (iii) such settlement, compromise or consent includes an unconditional release of the Indemnifying Party and its shareholders, partners, officers, directors, employees, agents, representatives and Affiliates from all liability arising out of such Claim. An Indemnifying Party may not, without the prior written consent of the Indemnified Party, settle or compromise any claim or consent to the entry of any judgment with respect to which indemnification is being sought hereunder unless such settlement, compromise or consent (x) includes an unconditional release of the Indemnified Party and its shareholders, partners, officers, directors, employees, agents, representatives and Affiliates from all liability arising out of such Claim, (y) does not contain any admission or statement suggesting any wrongdoing or liability on behalf of the Indemnified Party and (z) does not contain any equitable order, judgment or term that in any material manner affects, restrains or interferes with the business of the Indemnified Party or any of the Indemnified Party’s Affiliates.

(c) In the event an Indemnified Party claims a right to payment pursuant hereto, such Indemnified Party shall send written notice of such Claim to the appropriate Indemnifying Party. Such notice shall specify the basis for such Claim. The failure by any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it may have to such Indemnified Party with respect to any Claim made pursuant to this Section 10.3(c), it being understood that notices for Claims in respect of a breach of a representation or warranty must be delivered prior to the expiration of the Claims Period for such representation or warranty under Section 10.4. If the Indemnifying Party agrees it is liable for such Claim, it shall pay the amount of such liability to the Indemnified Party within 30 days, or, in the case of any notice in which the amount of the Claim (or any portion of the Claim) is estimated, within 30 days after such later date when the amount of such Claim (or such portion of such Claim) becomes finally determined. In the event the Indemnifying Party does not respond to such Claim or disputes its liability with respect to such Claim, such Indemnified Party and the appropriate Indemnifying Party shall, as promptly as possible, establish the merits and amount of such Claim by making good faith efforts to come to an agreement or, failing mutual agreement, by the exercise of such legal remedies as may be available, subject to Sections 10.4, 10.5, 10.7 and 10.9.

Section 10.4 Claims Period. The Claims Periods hereunder shall begin on the date hereof and terminate as follows:

(k) with respect to Seller Losses arising under Section 10.2(a) with respect to (i) any breach of Section 5.5 (Brokers, Finders and Investment Bankers), the Claims Period shall terminate upon the expiration of the applicable statute of limitations and (ii) any other breach of Article V, the Claims Period will expire on the date that is two years following the Closing Date; and

(l) with respect to Seller Losses arising under Sections 10.2(b), (d), (e) or (f), the Claims Period shall continue indefinitely.

Notwithstanding the foregoing, if, prior to the close of business on the last day of the applicable Claims Period, an Indemnifying Party shall have been properly notified of a claim for indemnity hereunder and such claim shall not have been finally resolved or disposed of at such date, such

claim shall continue to survive and shall remain a basis for indemnity hereunder until such claim is finally resolved or disposed of in accordance with the terms hereof.

Section 10.5 Liability Limits. Except as expressly provided in the third sentence of Section 10.3(a), notwithstanding anything to the contrary set forth herein, (a) the Purchaser Indemnified Parties shall not make a claim against the Sellers in respect of Purchaser Losses unless and until the aggregate amount of such Purchaser Losses exceeds $5,000,000 (the “Purchaser Deductible”), in which event the Purchaser Indemnified Parties may claim indemnification for all Purchaser Losses in excess of the initial $5,000,000; and (b) in no event shall the aggregate joint and several liability of the Sellers in respect of Purchaser Losses exceed $137,500,000 (the “Aggregate Cap”), except with respect to any Seller MTBE Liability, which shall not be subject the Aggregate Cap; provided, however, the amount of any Purchaser Loss for Seller MTBE Liability, if and when paid by the Sellers, shall apply against the Aggregate Cap with respect to all other Purchaser Losses.

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.

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.
