without materially affecting the economic value to the Company so that the portion thereof pertaining to Marathon’s Business was segregated, Marathon and/or its Affiliates, if permitted by the terms of such Marathon Joint Contracts, shall continue such Marathon Joint Contracts in effect until their stated expiration without regard to any available renewal options. Each of Marathon and/or its Affiliates and the Company shall perform its respective obligations under such Marathon Joint Contracts so as to not create a default thereunder. Neither Marathon and/or its Affiliates nor the Company will be obligated to extend credit to the other party.

Marathon and/or its Affiliates and the Company shall cooperate to obtain promptly all required consents to effectively permit the assignment of all Marathon Permits that are not Marathon Joint Permits. With respect to Marathon Joint Permits, Marathon and/or its Affiliates and the Company shall cooperate in seeking to obtain separate Marathon Permits for the Company and Marathon and/or its Affiliates if, in Marathon’s reasonable judgment, such efforts have a reasonable probability of success without adverse consequences to Marathon or its Affiliates. Each party shall comply with all terms and conditions of the Marathon Joint Permits pertaining to its respective business and, with respect to Marathon Permits allowing a stipulated amount and/or type of emissions or waste products, the Company shall be allocated its share thereof as provided in Schedule 5.3 to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter or if no such allocation is provided in Schedule 5.3 to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter, based on the historic practice of Marathon and its Affiliates prior to the Closing Date. Marathon and the Company shall indemnify, defend and hold harmless the other party and its Affiliates from and against any violations of any Marathon Joint Permit resulting from the acts or omissions of such party or its Affiliates or resulting from its utilization of more than its respective allocated share of emissions or waste products permitted under such Marathon Joint Permit.

purchase Financed Properties, (iv) funds expended to purchase assets that are substantially the same type of assets as the Financed Properties that were not included in Marathon’s Target Capital Expenditures or in Ashland’s Target Capital Expenditures, as applicable, because Marathon or Ashland, as the case may be, had intended to finance such purchases, (v) funds expended in connection with a Special Environmental Project except to the extent such funds were intended to be expended as part of Ashland’s Target Capital Expenditures, or (vi) funds expended in connection with Marathon’s obligations under Section 7.1(j).

(c) Within 60 days following the Closing, (i) Marathon shall prepare and deliver to Ashland a closing statement setting forth the actual amount of capital expenditures incurred by Marathon from January 1, 1997 through December 31, 1997 and (ii) Ashland shall prepare and deliver to Marathon a closing statement setting forth (A) the actual amount of capital expenditures incurred by Ashland from January 1, 1997 through December 31, 1997 and (B) the actual amount of capital expenditures incurred by Ashland in connection with the cumene production capacity expansion project at the Catlettsburg refinery (the “Cumene Project”) from January 1, 1997 through December 31, 1997 (each of (i) and (ii) are hereinafter referred to as a “Capital Expenditure Statement”), in each case, together with a certificate of such party’s independent public accountants confirming that such amount is derived from the accounting records of such party and that such amount was calculated in accordance with this Section 4.4. The Ashland Capital Expenditure Statement shall also set forth (i) the amount of capital expenditures included in Ashland’s Target Capital Expenditures related to the Cumene Project for expenditures in calendar year 1997 (the “Cumene Project 1997 Budget Amount”), (ii) the arithmetic sum of (A) the actual amount of capital expenditures incurred by Ashland from January 1, 1997 through December 31, 1997, plus (B) the Cumene Project 1997 Budget Amount, minus (C) the actual amount of capital expenditures incurred by Ashland in connection with the Cumene Project from January 1, 1997 through December 31, 1997, minus (D) the amount, if any, by which Ashland’s capital expenditures in calendar year 1997 were reduced as a result of any material reduction in the scope of the Cumene Project during such period (such arithmetic sum being hereinafter referred to as “Ashland’s Adjusted Capital Expenditures”).

(d) During the 60-day period following the other party’s receipt of the Capital Expenditure Statement and accountant’s certificate from the submitting party, the other party and its independent public accountants shall be permitted to review the working papers of the submitting party relating to the Capital Expenditure Statement and the working papers of such submitting party’s independent public accountants prepared in connection with their certification of the Capital Expenditure Statement. The Capital Expenditure Statement of a party shall become final and binding upon the parties on the sixtieth (60th) day following delivery thereof, unless the other party gives written notice of its disagreement with such Capital Expenditure Statement (a “Notice of Capital Expenditure Disagreement”) to the submitting party prior to the close of business on such date. Any Notice of Capital Expenditure Disagreement shall (i) specify in reasonable detail the nature of any disagreement so asserted, (ii) only include disagreements based either on (A) whether the actual capital expenditures of the submitting party were calculated in the manner provided for in this Section 4.4, (B) the amount of the Cumene Project 1997 Budget Amount or (C) mathematical or computational errors and (iii) be accompanied by a certificate of the other party’s independent public accountants that they concur with each of the positions taken

by the other party in the Notice of Capital Expenditure Disagreement. If a Notice of Capital Expenditure Disagreement is received by the submitting party in a timely manner, then the Capital Expenditure Statement (as revised in accordance with clause (i) or (ii) below) shall become final and binding upon Marathon and Ashland on the earlier of (i) the date Marathon and Ashland resolve in writing any differences they have with respect to the matters specified in the Notice of Capital Expenditure Disagreement and (ii) the date any disputed matters are finally resolved in writing by the Capital Expenditure Accounting Firm (as defined below).

(e) During the 30-day period following the delivery of a Notice of Capital Expenditure Disagreement, Marathon and Ashland shall seek in good faith to resolve in writing any differences which they may have with respect to the matters specified in the Notice of Capital Expenditure Disagreement. During such period, the submitting party and its independent public accountants shall be permitted to review the working papers of the other party relating to the Notice of Capital Expenditure Disagreement and the working papers of such other party’s independent public accountants prepared in connection with their certification of the Notice of Capital Expenditure Disagreement. At the end of such 30-day period, Marathon and Ashland shall submit to an independent public accounting firm (the “Capital Expenditure Accounting Firm”) for review and resolution any and all matters which remain in dispute and which were properly included in the Notice of Capital Expenditure Disagreement, in the form of a written brief. The scope of the Capital Expenditure Accounting Firm’s review shall be limited to only those matters which remain in dispute and which were properly included in the Notice of Capital Expenditure Disagreement. The Capital Expenditure Accounting Firm shall be such nationally recognized independent public accounting firm as shall be agreed upon by Marathon and Ashland in writing. The Capital Expenditure Accounting Firm’s decision shall be accompanied by a certificate of the Capital Expenditure Accounting Firm that it reached its decision in accordance with the provisions of this Section 4.4(e). The parties agree to use commercially reasonable best efforts to cause the Capital Expenditure Accounting Firm to render a decision resolving the matters submitted to the Capital Expenditure Accounting Firm within 30 days following submission. The parties agree that judgment may be entered upon the determination of the Capital Expenditure Accounting Firm in the Court of Common Pleas of Franklin County, Ohio and the United States District Court for the Southern District of Ohio. The fees and expenses of the Capital Expenditure Accounting Firm shall be borne by Marathon and Ashland in inverse proportion as they may prevail on matters resolved by the Capital Expenditure Accounting Firm, which proportionate allocations shall also be determined by the Capital Expenditure Accounting Firm at the time the determination of the Capital Expenditure Accounting Firm is rendered on the merits of the matters submitted. Any fees and disbursements of Marathon’s and Ashland’s independent public accounting firms incurred in connection with their review of the Capital Expenditure Statement and certification of any Notice of Capital Expenditure Disagreement shall be borne by the party retaining such accounting firm.

(f) In the event that Marathon believes that Marathon’s actual 1997 capital expenditures will be less than Marathon’s Target Capital Expenditures, Marathon may at any time prior to the determination by the Capital Expenditure Accounting Firm of its decision pursuant to Section 4.4(e) pay to the Company all or any part of its estimate of such shortfall in immediately available funds, plus interest on such payment at the Prime Rate from the Closing Date to the date

of payment. In the event that Ashland believes that Ashland’s Adjusted Capital Expenditures will be less than Ashland’s Target Capital Expenditures, Ashland may at any time prior to the determination by the Capital Expenditure Accounting Firm of its decision pursuant to Section 4.4(e) pay to the Company all or any part of its estimate of such shortfall in immediately available funds, plus interest on such payment at the Prime Rate from the Closing Date to the date of payment.

(g) If, as finally determined pursuant to this Section 4.4, Marathon’s Target Capital Expenditures exceeds the actual amount of Marathon’s actual capital expenditures for the period from January 1, 1997 through December 31, 1997, Marathon shall pay to the Company the amount of such shortfall less any amount paid to the Company pursuant to Section 4.4(f) (excluding interest) in immediately available funds, plus interest on such net payment at the Prime Rate from the Closing Date to the date of payment. If, as finally determined pursuant to this Section 4.4, Ashland’s Target Capital Expenditures exceeds the actual amount of Ashland’s Adjusted Capital Expenditures for the period, Ashland shall pay to the Company the amount of such shortfall less any amount paid to the Company pursuant to Section 4.4(f) (excluding interest) in immediately available funds, plus interest on such net payment at the Prime Rate from the Closing Date to the date of payment. If Marathon has paid an amount (excluding interest thereon) pursuant to Section 4.4(f) that is greater than the amount of Marathon’s actual 1997 capital expenditures as determined pursuant to this Section 4.4, then the Company shall promptly pay to Marathon the amount of such excess payment, without interest. If Ashland has paid an amount (excluding interest thereon) pursuant to Section 4.4(f) that is greater than the amount of Ashland’s Adjusted Capital Expenditures as determined pursuant to this Section 4.4, then the Company shall promptly pay to Ashland the amount of such excess payment, without interest.

(e) Compliance with Applicable Laws. Each Ashland Benefit Plan and all related trusts, insurance contracts, and funds have been maintained, funded and administered in substantial compliance in all material respects with all Applicable Laws. No Claims with respect to Ashland Benefit Plans (other than routine claims for benefits) or with respect to any fiduciary or other person dealing with any Ashland Benefit Plan are pending or threatened, and neither Ashland nor any ERISA Affiliate of Ashland has any Knowledge of any facts which could give rise to or be expected to give rise to any such actions, suits, investigations or claims.

(h) Guarantees and Other Obligations. Marathon agrees to maintain in effect or to cause its subsidiaries to maintain in effect to support the Company each Guarantee and other obligation specified on Schedule 7.1(h) to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter as required to be maintained after the Closing until the earlier of (i) the termination or expiration of such Guarantee or other obligation in accordance with its terms and (ii) the date the beneficiary of such Guarantee or other obligation agrees to release such Guarantee or other obligation on terms which would not impose any unreasonable financial cost or other burden on the Company.

Marathon shall be responsible for and shall indemnify and hold harmless the Company, Ashland and their respective Affiliates from and against any Claim or Loss to the extent such Claim or Loss arises out of such Indebtedness or the failure of Marathon or any of its Affiliates to timely make principal, premium or interest payments on such Indebtedness.

(a) Provision of Ashland Records. On or as promptly as practicable after the Closing Date, Ashland shall, and shall cause its Affiliates to, deliver to the Company all Ashland Records; provided that Ashland shall be entitled to retain a copy of any Ashland Record. From and after the Closing Date, all such books and records shall be the property of the Company.

(b) Access to Retained Records. Ashland shall maintain or cause to be maintained at its offices, in accordance with its record retention policies, the related material records and other documents held by Ashland on the Closing Date with respect to (i) the Ashland

Transferred Assets, (ii) the Ashland Assumed Liabilities or (iii) the conduct of the business of Ashland’s Business prior to the Closing Date, in each case which are not included in the Ashland Transferred Assets, and will make such records and other documents reasonably available, without charge, to representatives of Marathon and the Company at a reasonable place and time, it being understood that such representatives shall be entitled to make copies thereof as they shall deem necessary for purposes of making such records and documents available to appropriate Governmental Authorities or for other proper corporate purposes. Notwithstanding the foregoing, Ashland shall not be obligated to make available any such records or documents that are privileged, that Ashland is prohibited from disclosing by Applicable Law or that are the subject of binding confidentiality agreements with non-Affiliates of Ashland restricting their conveyance or disclosure to the Company; provided, however, that Ashland shall use its commercially reasonable best efforts to obtain the right from such non-Affiliates either to disclose such records to the Company or to transfer such confidentiality agreements to the Company.

(c) Production of Witnesses. After the Closing Date, Ashland shall make available to the Company, upon written request, its and its Affiliates’ directors, officers, employees and agents as witnesses to the extent that any such Person may reasonably be required in connection with any administrative or other proceedings which the Company may from time to time be contesting, asserting or defending against any Person that is not a party hereto or an Affiliate of a party hereto and which relates to (i) any transaction contemplated by this Agreement or (ii) any act, omission, occurrence or transaction prior to the Closing Date involving any of Ashland’s Business, provided that the same shall not unreasonably interfere with the conduct of Ashland’s Business. The Company shall reimburse Ashland for all reasonable out-of-pocket expenses incurred by Ashland in complying with any such request.

(d) Forwarding of Payments. Ashland shall, and shall cause its Affiliates to, promptly and in good faith forward, or cause to be forwarded, to the Company, in the manner directed by the Company, any payment of monies to which the Company or any subsidiary of the Company is entitled but which is made instead to Ashland or any of its Affiliates for whatever reason.

(e) Discharge of Liens. Ashland shall retain the responsibility to discharge, at its cost, any Liens on any Ashland Transferred Asset existing on the Closing Date unless such Lien is a Permitted Encumbrance.

(f) Tax Matters. (i) For any taxable period of any of the Ashland Subsidiaries that includes (but does not end on) the Closing Date, the Company shall timely prepare and file with the appropriate Governmental Authorities all returns required to be filed and shall pay all Taxes due with respect to such returns, except as otherwise agreed by Marathon, Ashland and the Company; provided that Ashland shall reimburse the Company for any amount owed by Ashland pursuant to Section 9.4(b) and paid by the Company with respect to the taxable periods covered by such returns. For any taxable period of any of the Ashland Subsidiaries that ends on or before the Closing Date, Ashland shall timely prepare and file with the appropriate Governmental Authorities all returns required to be filed, and shall pay all Taxes due with respect to such returns; provided that the Company shall reimburse Ashland for any amount assumed by the

Company pursuant to Section 3.3(i) and paid by Ashland or any of its Affiliates. The Company and Ashland agree to cause the Ashland Subsidiaries to file all returns for the period including the Closing Date on the basis that the relevant taxable period ended as of the close of business on the Closing Date or, if the Closing Date is between January 1, 1998 and January 10, 1998, ended as of the close of business on December 31, 1997, unless the relevant Governmental Authority will not accept a return filed on that basis.

(ii) Ashland shall cause the provisions of any Tax sharing agreement between Ashland or any of its Affiliates, on the one hand, and any Ashland Subsidiary, on the other hand, to be terminated on or before the Closing Date. After the Closing Date, no party shall have any rights or obligations under any such Tax sharing agreement.

(g) Accounting Treatment. From the date hereof until the date of the filing by USX of its Annual Report on Form 10-K with the Securities and Exchange Commission for (i) the fiscal year ending December 31, 1998 in the event that the Closing Date occurs in 1997, or (ii) the fiscal year ending December 31, 1999 in the event that the Closing Date occurs in 1998, Ashland will take all reasonable action requested by Marathon (a “Requested Action”) to ensure that the transactions contemplated by this Agreement will be accounted for on the purchase method by Marathon under the provisions of Accounting Principles Board Opinion No. 16. It is understood and agreed that the ability of Marathon to consolidate the Company’s Business in its financial statements is a prerequisite to Marathon’s ability to account for the transactions contemplated by this Agreement on the purchase method and Requested Action may include action related to consolidation accounting treatment necessary to achieve purchase accounting treatment. For purposes of this Section 7.2(g), a Requested Action will be deemed “reasonable” (a “Reasonable Requested Action”) only if (i) the Requested Action is reasonably related to the issue of Marathon’s ability to preserve purchase accounting treatment (based on the Relevant Accounting Factors); (ii) Marathon delivers to Ashland an opinion of its independent public accounting firm (based on the Relevant Accounting Factors) to the effect that (A) the Requested Action is necessary for Marathon to preserve purchase accounting treatment and (B) the Requested Action constitutes the least possible amendment of Ashland’s rights necessary for Marathon to preserve purchase accounting treatment; and (iii) the issue of Marathon’s ability to preserve purchase accounting treatment did not arise as a result of Marathon, USX or any of their respective Affiliates having taken any action unrelated to the Company or the Company’s Business. If Ashland agrees to take the Requested Action, then Marathon shall, and shall cause its Affiliates to, take all such actions as are necessary to reinstate the rights that Ashland forfeited in having taken the Requested Action as soon as reasonably possible consistent with the preservation by Marathon of purchase accounting treatment. In the event that the Requested Action would have a material adverse affect on Ashland’s rights under the LLC Agreement or the other Transaction Documents, Ashland shall negotiate in good faith with Marathon to determine whether and to what extent it will take the Requested Action; provided that Ashland shall have the right at any time to terminate its obligations under this Section 7.2(g) by paying Marathon an amount in liquidated damages equal to $10,000,000. Ashland shall be deemed to have negotiated in good faith if it is not willing to take the Requested Action on the basis of an opinion from its independent public accounting firm (based on the Relevant Accounting Factors) that the Requested Action is not a Reasonable Requested Action. If Ashland is not willing to take the

Requested Action, then such dispute shall be finally resolved by a third nationally-recognized independent public accounting firm jointly selected by Marathon and Ashland. The fees and expenses of such third accounting firm shall be paid 50% by Marathon and 50% by Ashland. If such third accounting firm determines (based on the Relevant Accounting Factors) that the Requested Action constitutes a Reasonable Requested Action, Ashland shall have the right to either (i) take such action or (ii) pay Marathon an amount in liquidated damages equal to $10,000,000. If such third accounting firm determines (based on the Relevant Accounting Factors) that the Requested Action does not constitute a Reasonable Requested Action, then Ashland shall not be required to take the Requested Action or pay Marathon any amount in damages in respect thereof. It is understood and agreed that, except as expressly provided in this Section 7.2(g), Ashland shall have no obligation or liability to Marathon in the event that Marathon is either (i) unable to account for the transactions contemplated by this Agreement on the purchase method under the provisions of Accounting Principles Board Opinion No. 16 as a purchase by Marathon of Ashland’s Business for accounting purposes or (ii) is unable to consolidate the Company’s Business in its financial statements.

(h) Guarantees and Other Obligations. Ashland agrees to maintain in effect or to cause its subsidiaries to maintain in effect to support the Company each Guarantee and other obligation specified on Schedule 7.2(h) to the Ashland Asset Transfer and Contribution Agreement Disclosure Letter as required to be maintained after the Closing until the earlier of (i) the termination or expiration of such Guarantee or other obligation in accordance with its terms and (ii) the date the beneficiary of such Guarantee or other obligation agrees to release such Guarantee or other obligation on terms which would not impose any unreasonable financial cost or other burden on the Company.

(i) LOOP/LOCAP. Ashland agrees that if after the Closing it receives any dividends or distributions from LOOP LLC or LOCAP Inc. in respect of the Ashland LOOP/LOCAP Interest, Ashland shall promptly forward to the Company an amount equal to such dividends or distributions net of any Taxes that are either imposed on Ashland with respect to such dividends or distributions or withheld from such dividends or distributions.

(j) Indebtedness. Ashland agrees to make, or cause its Affiliates to make, all principal, premium and interest payments on all Indebtedness assumed by the Company or its subsidiaries pursuant to Section 3.3(d) in accordance with the terms (including as to the amount and timing of all such payments) of such Indebtedness. In the event Ashland or its Affiliates fail to make any such payments as and when required under the terms of such Indebtedness and as a result thereof, the Company is required to make any such payment, Ashland agrees to reimburse the Company promptly for all amounts paid by the Company in respect of such Indebtedness. Ashland shall be responsible for and shall indemnify and hold harmless the Company, Marathon and their respective Affiliates from and against any Claim or Loss to the extent such Claim or Loss arises out of such Indebtedness or the failure of Ashland or any of its Affiliates to timely make principal, premium or interest payments on such Indebtedness.

(k) Ashland Special Environmental Projects. Ashland shall take, or cause to be taken, at its sole expense and as soon as reasonably practical, all Special Environmental Projects

set forth on Schedule 7.2(k) to the Ashland Asset Transfer and Contribution Agreement Disclosure Letter in accordance with the terms and provisions set forth thereon, with such immaterial changes (taken in the aggregate) to the Special Environmental Projects that are the subject of ongoing negotiations with the National Enforcement Investigation Center of the United States Environmental Protection Agency that are agreed to by the National Enforcement Investigation Center of the United States Environmental Protection Agency. The obligations of Ashland under this Section 7.2(k) with respect to a Special Environmental Project shall terminate upon the earlier to occur of the completion of such Special Environmental Project to the satisfaction of the appropriate Governmental Authority and the occurrence of a Termination Event with respect to such Special Environmental Project. It is expressly understood and agreed that neither the Company nor Marathon will be entitled to assert that the conditions that are the subject of a Special Environmental Project constitute a breach of any of Ashland’s representations and warranties contained in Article VI. To the extent that the Company manages the performance of such actions, it shall act with the same degree of diligence and care that it would exercise if performing such actions at its sole expense and shall use commercially reasonable best efforts to complete the project at the lowest overall obtainable cost consistent with the scope of the project. The Company shall not engage any independent contractors related to the performance of any Special Environmental Project without the prior written consent of Ashland, which shall not unreasonably be withheld. Ashland shall have the right to direct and control all discussions, negotiations and proceedings with Governmental Authorities, including the right, after notice to and consultation with the Company, to settle or otherwise resolve any Environmental Violation giving rise to or forming part of such Special Environmental Project; provided, that Ashland may not enter into any such settlement or resolution that would reasonably be expected to have a Material Adverse Effect on the Company’s Business without the prior written consent of the Company, which consent will not be unreasonably withheld. Ashland shall offer the Company the opportunity to participate in all discussions, negotiations or proceedings with or before Governmental Authorities or other persons related to such Special Environmental Project (other than the current negotiations with the National Enforcement Investigation Center of the United States Environmental Protection Agency in connection with its multi-media environmental inspection).

(l) Marine Preservation Association. Subject to Section 9.3(j) below, Ashland agrees that it will maintain its membership in the Marine Preservation Association in good standing after Closing and that, upon the request of the Company, it will either use its commercially reasonable best efforts to assign such membership to the Company or a subsidiary of the Company or resign its membership.

Section 7.3 Certain Covenants of the Company.

(a) Access to Records. The Company shall maintain or cause to be maintained at its offices, in accordance with its record retention policies, all the Marathon Records and the Ashland Records, and will make the Marathon Records and the Ashland Records reasonably available, without charge, to representatives of Marathon and Ashland, as the case may be, at a reasonable place and time, it being understood that such representatives shall be entitled to make copies thereof as they shall deem necessary for purposes of making such Records available to

appropriate Governmental Authorities or for other proper corporate purposes. The parties hereto agree that this right of access to Marathon Records and Ashland Records is in addition to the rights that Marathon and Ashland each have as Members of the Company to examine the books and records of the Company under the LLC Agreement.

(b) Future Sales Activity.

(c) Forwarding of Payments.

(e) Release of Guarantees. The Company shall use its commercially reasonable best efforts after Closing to cause each of USX, Marathon, Ashland and their respective Affiliates to be released as guarantors or obligors under the Guarantees and other obligations set forth on Schedule 3.5 to the Parent Agreement Disclosure Letter, Schedule 7.1(h) to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter and Schedule 7.2(h) to the Ashland Asset Transfer and Contribution Agreement Disclosure Letter, respectively; provided that the Company shall not be obligated to incur more than a reasonable cost in connection with such releases.

(f) Litigation. Upon the request of Marathon or Ashland, as applicable, the Company shall handle the administration of Third-Party Claims that are the subject of Marathon’s indemnity obligation contained in Section 9.1(d) or Ashland’s indemnity obligation contained in Section 9.2(d), respectively (including Claims that would be subject to such indemnity obligations

but for the application of the $100,000 threshold contained in Section 9.1(d) and Section 9.2(d)). The Company shall not be entitled to reimbursement from Marathon or Ashland for the administrative costs (other than out-of-pocket costs) in handling such Third-Party Claims, whether or not Marathon or Ashland ultimately is required to indemnify the Company pursuant thereto.

(g) Certain Expenses and Liabilities Related to Information Technology.

(b) Notice of Third Party Claim. If any Third Party Claim is asserted against an Indemnified Party and such Indemnified Party intends to seek indemnification hereunder from a party to this Agreement (the “Indemnifying Party”), then such Indemnified Party shall give notice of the Third Party Claim to the Indemnifying Party as soon as practicable after the Indemnified Party has reason to believe that the Indemnifying Party will have an indemnification obligation with respect to such Third Party Claim and shall provide the Indemnifying Party with all papers served with respect to such Third Party Claim. Such notice shall describe in reasonable detail the nature of the Third Party Claim, an estimate of the amount of damages attributable to the Third Party Claim and the basis of the Indemnified Party’s request for indemnification under this Agreement. The failure of the Indemnified Party to so notify the Indemnifying Party of the Third Party Claim shall not relieve the Indemnifying Party from any duty to indemnify hereunder unless and to the extent that the Indemnifying Party demonstrates that the failure of the Indemnified Party to promptly notify it of such Third Party Claim prejudiced its ability to defend such Third Party Claim; provided, that the failure of the Indemnified Party to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability which it may have to the Indemnified Party otherwise than under this Agreement. Thereafter, the Indemnified Party shall deliver to the Indemnifying Party, within five Business Days after the Indemnified Party’s receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Party relating to the Third Party Claim.

(c) Right of Indemnifying Party to Control Defense of Third Party Claims. The Indemnifying Party shall have the right to participate in, or assume control of, and the Indemnifying Party’s insurance carrier shall have the right to participate in, the defense of the Third Party Claim at its own expense by giving prompt written notice to the Indemnified Party, using counsel of its choice reasonably acceptable to the Indemnified Party. If it elects to assume control of the defense of such Third Party Claim, the Indemnifying Party shall defend such Third Party Claim by promptly and vigorously prosecuting all appropriate proceedings to a final conclusion or settlement. After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such Third Party Claim, the Indemnified Party shall have the right to participate in the defense of the Third Party Claim using counsel of its choice, but the Indemnifying Party shall not be liable to the Indemnified Party hereunder for any legal or other expenses subsequently incurred by the Indemnified Party in connection with its participation in the defense thereof unless (i) the employment thereof has been specifically authorized in writing by the Indemnifying Party, (ii) the Indemnifying Party fails to assume the defense or diligently prosecute the Third Party Claim or (iii) there shall exist or develop a conflict that would ethically prohibit counsel to the Indemnifying Party from representing the Indemnified Party. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim that the Indemnifying Party elects to contest, including the making of any related counterclaim against the Third Party asserting the Third Party Claim or any cross-complaint against any Person, in each case only if and to the extent that any such counterclaim or cross-complaint arises from the same actions or facts giving rise to the Third Party Claim. The Indemnifying Party shall have the right, acting in good faith and with due regard to the interests of the Indemnified Party, to control all decisions regarding the handling of the defense without the consent of the Indemnified Party, but shall not have the right to admit liability with respect to, or compromise, settle or discharge any Third Party Claim or consent to the entry of any judgment with respect to such Third Party Claim without the consent of the Indemnified Party, which consent shall not be unreasonably withheld, unless such settlement, compromise or consent includes an unconditional release of the Indemnified Party from all liability and obligations arising out of such Third Party Claim and which would not otherwise adversely affect the Indemnified Party

(d) Control of Third Party Claim by the Indemnified Party. If the Indemnifying Party fails to assume the defense of a Third Party Claim within thirty (30) days after receipt of written notice of the Third Party Claim, then the Indemnified Party shall have the right to defend the Third Party Claim by promptly and vigorously prosecuting all appropriate proceedings to a final conclusion or settlement. The Indemnifying Party shall have the right to participate in the defense of the Third Party Claim using counsel of its choice, but the Indemnified Party shall not be liable to the Indemnifying Party hereunder for any legal or other expenses incurred by the Indemnifying Party in connection with its participation in the defense thereof. If requested by the Indemnified Party, the Indemnifying Party agrees to cooperate with the Indemnified Party and its counsel in contesting any Third Party Claim that the Indemnified Party elects to contest, including the making of any related counterclaim against the Third Party asserting the Third Party Claim or any cross-complaint against any Person, in each case only if and to the extent that any such counterclaim or cross-complaint arises from the same actions or facts giving rise to the Third Party Claim. The Indemnified Party shall have the right, acting in good faith and with due regard

to the interests of the Indemnifying Party, to control all decisions regarding the handling of the defense without the consent of the Indemnifying Party, but shall not have the right to compromise or settle any Third Party Claim or consent to the entry of any judgment with respect to such Third Party Claim without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld, unless such settlement, compromise or consent includes an unconditional release of the Indemnifying Party from all liability and obligations arising out of such Third Party Claim.

The indemnification provisions contained in this Article IX, including the provisions of Section 9.11(b), Section 9.11(c) and Section 9.16 hereof and the provisions of Section 7.3(b) of the Master Formation Agreement, shall survive (subject to the provisions of Section 7.5(b), Section 7.6(b), Article VIII, Section 9.10 and Section 9.17 of the Master Formation Agreement and Section 9.14(b), Section 9.15(b), Section 11.8 and Section 11.15 hereof and subject to termination pursuant to Section 7.2 of the Master Formation Agreement and Section 9.6(e)(i) and Section 9.8(k) hereof) any Transfer by Marathon or Ashland of its Membership Interests to a third party or the other Member pursuant to Article X of the LLC Agreement.

To the extent that two or more of Marathon, Ashland and the Company are liable hereunder with respect to the same Claim, the Losses will be apportioned among Marathon, Ashland and the Company in proportion to the extent to which the activities of each contributed to the cause of the Claim or resulting Losses; provided that the apportionment of Environmental Loss shall be governed by Section 9.8(g). To the extent that a Transferred Employee has made a Claim in respect of sickness or death as a result of exposure, by reason of employment or otherwise, to any Hazardous Substances at his place of employment both before and after the Closing Date, the liability of Marathon or Ashland, on the one hand, and the Company, on the other hand, shall be prorated utilizing all pertinent factors, such as the length of employment of such Transferred Employee by Marathon or Ashland, as the case may be, and the Company, the nature and duration of the alleged exposure to Hazardous Substances, the length of time such Hazardous Substances were present in the workplace at Marathon, Ashland or the Company, as applicable, and, in the case of allegations of exposure to multiple Hazardous Substances, the relative toxicity of each such Hazardous Substance.

(i) Notwithstanding anything in this Agreement to the contrary, in order to provide for a uniform and expeditious resolution of all Claims for Environmental Losses, Section 7.2(k), Section 9.1(c), Section 9.1(e), Section 9.2(c), Section 9.2(e), Section 9.3(a), Section 9.3(e), Section 9.8 and Section 9.10 shall provide the sole and exclusive remedy for Marathon, Ashland or the Company, as applicable, with respect to any matter constituting, relating to or arising out of an Environmental Loss and as to which any other Article of this Agreement is also arguably applicable (other than the provisions of Section 9.1(b) and Section 9.2(b), which shall prevail in the event there is a conflict with such provisions). By way of example, to the extent that circumstances are discovered that could be alleged to constitute a breach of a representation or warranty relating to environmental matters which

circumstances also give rise to an indemnified Environmental Loss under the provisions of Section 7.2(k), Section 9.1(c), Section 9.1(e), Section 9.2(c), Section 9.2(e), Section 9.3(a), Section 9.3(e), Section 9.8 and Section 9.10 then all procedural and substantive requirements and qualifications of such enumerated sections, including application of the Individual Threshold Amounts in lieu of any other indemnity thresholds arguably applicable to the matter, shall govern resolution of any Claim arising from such breach, and no indemnity payments made pursuant to such enumerated sections shall be counted towards any thresholds, baskets or other financial terms or limitations otherwise applicable under this Agreement. In the event there is a conflict between the Claims procedures of Section 9.6 and the Claims procedures of Section 9.8 with respect to a Claim relating to an Environmental Loss, the provisions of Section 9.8 shall prevail.

(ii) NOTHING CONTAINED IN THIS AGREEMENT OR ANY OTHER TRANSACTION DOCUMENT (INCLUDING THE DISCLOSURE LETTERS HERETO AND THERETO AND ANY CERTIFICATE FURNISHED IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER TRANSACTION DOCUMENT) SHALL BE DEEMED OR CONSTRUED TO BE A REPRESENTATION, WARRANTY OR COVENANT BY MARATHON OR ASHLAND RELATING TO OR ARISING OUT OF ANY ENVIRONMENTAL CONTAMINATION, ENVIRONMENTAL LAW, ENVIRONMENTAL LOSS, ENVIRONMENTAL REQUIREMENT OR ENVIRONMENTAL VIOLATION, IT BEING UNDERSTOOD THAT SECTIONS 7.2(k), 9.1(c), 9.1(e), 9.2(c), 9.2(e), 9.3(a), 9.3(e), 9.8 AND 9.10 PROVIDE THE SOLE AND EXCLUSIVE REMEDY FOR MARATHON, ASHLAND OR THE COMPANY, AS APPLICABLE, WITH RESPECT TO ANY MATTER CONSTITUTING, RELATING TO OR ARISING OUT OF AN ENVIRONMENTAL LOSS, EXCEPT AS EXPRESSLY PROVIDED IN THE LEASE AGREEMENTS SUBSTANTIALLY IN THE FORMS ATTACHED AS EXHIBITS X-0, X-0, X-0, X-0, X-0 AND K-7 TO THIS AGREEMENT AND IN THE COMMERCIAL DOCUMENTS.

(iii) IN FURTHERANCE OF THE FOREGOING, EACH OF THE PARTIES HERETO HEREBY WAIVES, FROM AND AFTER THE CLOSING, ANY AND ALL RIGHTS, CLAIMS AND CAUSES OF ACTION RELATING TO THIS AGREEMENT, THE MASTER FORMATION AGREEMENT AND THE OTHER CONVEYANCE DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY WITH RESPECT TO ANY MATTER CONSTITUTING, RELATING TO OR ARISING OUT OF AN ENVIRONMENTAL LOSS (OTHER THAN CLAIMS OR CAUSES OF ACTION ARISING FROM FRAUD) IT MAY HAVE AGAINST THE OTHER PARTIES HERETO ARISING UNDER OR BASED UPON APPLICABLE LAW (EXCEPT PURSUANT TO THE PROVISIONS SET FORTH IN SECTIONS 7.2(k), 9.1(c), 9.1(e), 9.2(c), 9.2(e), 9.3(a), 9.3(e), 9.8 AND 9.10 AND THE PROVISIONS OF APPENDIX B AND EXCEPT AS EXPRESSLY PROVIDED IN THE LEASE AGREEMENTS SUBSTANTIALLY IN THE FORMS ATTACHED AS EXHIBITS X-0, X-0, X-0, X-0, X-0 AND K-7 TO THIS AGREEMENT AND IN THE COMMERCIAL DOCUMENTS).

(c) Procedures for Asserting a Claim for an Environmental Loss. In order to effect the intent of the parties that all Environmental Losses be handled in a manner that minimizes, to the greatest extent practical, the obligations of Marathon and Ashland, as applicable, consistent with the operational requirements of the Company, sound management practices and the requirements of Environmental Law, Marathon and Ashland shall establish the Claims Review Committee as soon as practicable after the Closing Date, and the Company shall follow the procedures outlined below in Asserting any Claim for indemnification for any Environmental Loss (other than an Environmental Loss that is reasonably expected to be less than or equal to fifty percent (50%) of the applicable Individual Threshold Amount). For the avoidance of doubt, if the Company reasonably expects an Environmental Loss to be less than or equal to fifty percent (50%) of the applicable Individual Threshold Amount and therefore does not follow the procedures outlined below, but subsequently reasonably expects such Environmental Loss to exceed fifty percent (50%) of the applicable Individual Threshold Amount, it shall thereafter be required to follow all of the procedures outlined below with respect to such Environmental Loss.

(i) As soon as the Company becomes aware of circumstances that could reasonably be expected to lead to an Environmental Loss, the Company shall define the nature and extent of the Environmental Loss in writing, using a degree of detail reasonably necessary to inform the Indemnifying Party of the nature and scope of, and the justification for, any Claim for any Environmental Loss.

(ii) The Company shall develop a detailed assessment of the facts, conditions and circumstances giving rise to the Environmental Contamination or Environmental Violation underlying the Environmental Loss, using recognized environmental auditing and/or site assessment practices, as applicable. Pursuant to the terms of the Joint Defense Agreement, attached hereto as Exhibit N, the Company shall provide the Indemnifying Party copies of, and access to, all pertinent data and materials. In addition, if the assessment of the Environmental Loss includes discussions or meetings with Governmental Authorities, the Company, consistent with Section 9.8(i) hereof, shall provide the Indemnifying Party with timely prior notice of, and the opportunity to participate in, all such discussions or meetings.

(iii) At the conclusion of the assessment process, if either the Company or the Indemnifying Party reasonably believes that the nature, scope or conduct of the Company’s response to the Environmental Violation or Environmental Loss may give rise to a Loss that is either outside the scope of the indemnity or beyond the agreed-upon obligations of the Indemnifying Party pursuant to this Article IX, such as selection of a remedial option that does not address Environmental Contamination for the Lowest Remediation Cost, either party may refer the matter to the Claims Review Committee for prompt consideration.

(iv) The Company may solicit bids from recognized environmental engineering and consulting firms to conduct any required Remediation Activities or to assist the Company in resolution of any Environmental Violation, as applicable.

(v) The Company shall develop a formal authorization request proposal to be submitted to the Indemnifying Party based on the Company’s review and selection of remedial, engineering and legal options available to address the Environmental Violation or to undertake the Remediation Activities. In making this submission, the Company shall clearly designate its proposal for effecting the Remediation Activities at the Lowest Remediation Cost.

(vi) Within 15 days of receipt of this submission, the Indemnifying Party shall either approve the submission as the Lowest Remediation Cost option or request a meeting of the Claims Review Committee, which shall be convened within 10 days of the Indemnifying Party’s request to review the Company’s submission.

(vii) The Claims Review Committee, in all cases acting in a timely and expeditious matter, shall either (A) reach a consensus that the Company’s chosen option is the Lowest Remediation Cost option in whole or in part, and return that portion of the Claim to the Indemnifying Party for payment in accordance with the provisions of Article IX, or if it is unable to make such a determination or to resolve the issues arising out of this submission, (B) return the submission to the Company and the Indemnifying Party who may then seek recourse, if appropriate, in accordance with the dispute resolution provisions attached as Appendix B to this Agreement.

(viii) In the case of any matter involving a Loss that could reasonably be anticipated to give rise to an Extraordinary Environmental Loss, the Indemnifying Party may elect to give notice to the Company that the Claims Review Committee procedure need not be followed and that the Indemnifying Party will compel the Company to proceed directly to formal dispute resolution under the procedures outlined in Appendix B attached hereto, to demonstrate that the Company’s chosen option represents the Lowest Remediation Cost to address any Environmental Contamination at issue.

The parties do not intend that the foregoing procedures obstruct or hinder the Company in any manner in the operation of its Business or its response to any actual or alleged Environmental Contamination or Environmental Violation, but rather intend that the foregoing procedures provide a mechanism and forum for discussion and resolution of disagreements relating to actual and potential Environmental Losses prior to the invocation of the dispute resolution mechanism or other remedies under this Agreement. Notwithstanding any limits on the indemnity obligations of an Indemnifying Party in this Section 9.8, nothing contained herein shall be construed to prevent the Company from pursuing Remediation Activities at other than the Lowest Remediation Cost.

(d) Access to Environmental Records. Consistent with the procedures outlined in the Joint Defense Agreement, Marathon and Ashland shall have the right to review all Company environmental, health and safety audit procedures, schedules, reports, protocols and findings, copies of which shall be provided by the Company to Marathon or Ashland, as the case may be, upon reasonable request.

(e) Reduction of Environmental Indemnity Obligation. If Marathon is obligated to indemnify an Indemnified Party for any Environmental Loss (other than Environmental Contamination that is the subject of a Marathon Consent Decree or a Marathon Ongoing Remediation or Marathon Designated UST Environmental Contamination) or if Ashland is obligated to indemnify an Indemnified Party for any Environmental Loss (other than Environmental Contamination that is the subject of an Ashland Consent Decree or an Ashland Ongoing Remediation or Ashland Designated UST Environmental Contamination), the amount of the indemnity obligation shall be equal to the amount of such indemnifiable Environmental Loss times a percentage determined by the date on which the Environmental Loss was first Asserted against the Indemnified Party as set forth below (such indemnity obligation, as so reduced by this Section 9.8(e), to survive the Closing without termination, except to the extent set forth in Section 9.8(k)):


	Column 1	Column 2
If Asserted Against the Indemnified Person During the Twelve-Month Period Ending on the Following Anniversary of the Closing Date:	Percentage of Indemnifiable Environmental Loss Payable by the Indemnifying Party (Excluding Certain New RCRA Environmental Losses)⁽¹⁾	Percentage of Indemnifiable Environmental Loss Payable by the Indemnifying Party (Certain New RCRA Environmental Losses)⁽¹⁾
First through Fifth	100%	100%
Sixth	80%	100%
Seventh	60%	100%
Eighth	40%	100%
Ninth	20%	100%
Tenth	0%	100%
Eleventh	0%	80%
Twelfth	0%	60%
Thirteenth	0%	40%
Fourteenth	0%	20%
Thereafter	0%	0%

⁽¹⁾

For purposes of this Section 9.8(e) and at all times subject to the obligations of the Company contained in Section 9.8(a), the amount of the indemnity obligation with respect to a New RCRA Environmental Loss arising in whole or in part from an act or omission of an employee, agent or independent contractor of the Company shall be reduced in accordance with column 1 above and the amount of the indemnity obligation with respect to a New RCRA Environmental Loss arising in any other manner shall be reduced in accordance with column 2 above.

(f) Closed or Abandoned Refineries. Notwithstanding any other provision of this Article IX, in the event any Marathon Refinery or Ashland Refinery is closed or abandoned, in whole or in part, by the Company during the eight-year period following the Closing Date, the costs of removing equipment and conducting any new Remediation Activities to the extent necessitated by such closure or abandonment, for the Lowest Remediation Cost and subject to Section 9.8(h), whenever incurred, will be shared equally by Marathon and Ashland, regardless of

whether or not minor operations are continued on the site or immediate cleanup is required. The process of any such closure and abandonment shall be supervised by the Company, in accordance with the terms of Section 9.8(c) and Section 9.8(i). If any Marathon Refinery or Ashland Refinery is closed or abandoned, in whole or in part, by the Company more than eight years after the Closing Date, any such costs will be borne in full by the Company.

(g) Apportionment of Liability for Environmental Losses. Without altering or affecting in any manner the provisions of Section 9.8(e), to the extent that two or more of Marathon, Ashland and the Company are liable hereunder with respect to the same Environmental Loss, the Environmental Loss will be apportioned among Marathon, Ashland and the Company in proportion to the extent to which the activities of each party contributed to the cause of the Environmental Loss, taking into consideration all pertinent factors, including the length of ownership by such parties of the affected property during the time of the act, event or occurrence giving rise to the Environmental Loss and the use made of such property by such parties.

(h) Governing Environmental Law. In the event that Marathon or Ashland becomes obligated to indemnify the Company pursuant to Section 9.1(c), Section 9.1(e), Section 9.2(c), Section 9.2(e) or Section 9.8(f), as the case may be, for Environmental Contamination, Marathon or Ashland, as the case may be, will be obligated to indemnify the Company for the Lowest Remediation Cost for Remediation Activities required under then-applicable Environmental Law and consistent with the then-current operations of the sites involved, and will also be obligated to indemnify the Company for the installation of new improvements and the making of repairs and alterations to prevent such Environmental Contamination from continuing, and in each case at the Lowest Remediation Cost and, in the case of Section 9.1(c) and Section 9.2(c), subject to reduction pursuant to Section 9.8(e). Notwithstanding the foregoing, in no event shall Marathon or Ashland have any indemnity obligation for Environmental Contamination for which a Termination Event has occurred prior to the time at which the Company first Asserts a Claim for indemnification. Marathon’s indemnity obligations under Section 9.1(c) and Ashland’s indemnity obligations under Section 9.2(c) with respect to Environmental Violations shall be limited to the liability arising under, and the minimum level of improvements, repairs, alterations or other action required under, Environmental Laws or Environmental Requirements in effect in the jurisdiction with authority over such Environmental Violation on the Closing Date, taking into account all available engineering or institutional controls consistent with the then-current operations of the sites involved.

(i) Control of Remediation and Related Activities. (i) Other than as provided in Section 7.2(k), notwithstanding the provisions of Section 9.6 and in accordance with the provisions of Section 9.8(c) hereof and without prejudice to its rights to indemnification hereunder, the Company shall have the right to direct and control (A) any Remediation Activities, whether or not indemnified by Marathon or Ashland pursuant to this Article IX, including determining the scope, extent, duration and cost of such Remediation Activities, whether or not the cost of such activities exceeds the Lowest Remediation Cost or is otherwise beyond the indemnification obligations of the Indemnifying Party, and (B) all discussions, negotiations and proceedings with Governmental Authorities and Third Parties in connection therewith, except as provided in

Section 9.8(i)(ii). Prior to undertaking significant, nonemergency Remediation Activities, the Company shall consult with the Indemnifying Party concerning their scope, extent, duration and cost and shall, in accordance with the provisions of the preceding sentence, consider employing a third party contractor recommended by the Indemnifying Party who has reasonably and in good faith estimated the cost of effecting such Remediation Activities at a materially lower cost than that estimated by the Company. In addition, the Company shall (x) serve notice of and schedule nonemergency activities in advance so that the Indemnifying Party will have the opportunity to be present during the conduct of such activities, (y) promptly provide the Indemnifying Party with copies of any reports, tests or studies, notices or filings regarding the Environmental Contamination or condition in question and reasonable access to the Company’s employees and facilities, contractors or consultants, to discuss and review the foregoing and (z) offer the Indemnifying Party the opportunity to participate in all discussions, negotiations or proceedings with or before Governmental Authorities or third parties related to such Environmental Losses.

(ii) With respect to a proceeding relating to an Extraordinary Environmental Loss, after timely notice to the Company, the Indemnifying Party may elect to assume the right to direct and control all discussions, negotiations and proceedings with Governmental Authorities, including the right, after notice to and consultation with the Company, to settle or otherwise resolve any Environmental Violation giving rise to or forming part of such Extraordinary Environmental Loss; provided, that the Indemnifying Party may not enter into any such settlement or resolution that would reasonably be expected to have a Material Adverse Effect on the Company’s Business without the prior written consent of the Company, which consent will not unreasonably be withheld. If the Indemnifying Party elects to control the proceedings relating to an Extraordinary Environmental Loss as set forth in the preceding sentence, the Indemnifying Party shall offer the Company the opportunity to participate in all discussions, negotiations or proceedings with or before Governmental Authorities or third parties related to such Extraordinary Environmental Loss.

(j) Environmental Losses Discovered as a Result of Construction Activities. Notwithstanding any other provisions of Section 9.8 to the contrary, but otherwise subject to the terms, conditions, restrictions and limitations of Section 9.8 and Section 9.16, the obligation of Marathon or Ashland, as applicable, to indemnify the Company Indemnified Persons for Environmental Losses arising from Remediation Activities required in connection with Environmental Contamination identified by the Company during the conduct of construction activities undertaken by the Company in the ordinary course at any of the facilities of the Company’s Business, shall be limited to the Lowest Remediation Cost consistent with, and taking into account the purposes and timing of, the construction in question. In the event that the Company, prior to the commencement of any construction activities at a construction site (other than at a Marathon Service Station) included in the Marathon Transferred Assets, knows of pre-Closing Environmental Contamination at the construction site or knows of specific facts from which it could reasonably be concluded that pre-Closing Environmental Contamination exists at the construction site, then Marathon will be obligated to indemnify the Company Indemnified Persons for 50% of the cost of all Remediation Activities relating to such pre-Closing

Environmental Contamination, subject to the applicable Individual Threshold Amount; provided, that in no event shall Marathon’s aggregate indemnity obligation with respect to all Claims made under this Section 9.8(j) exceed $4,000,000. In the event that the Company, prior to the commencement of any construction activities at a construction site (other than at an Ashland Service Station) included in the Ashland Transferred Assets, knows of pre-Closing Environmental Contamination at the construction site or knows of specific facts from which it could reasonably be concluded that pre-Closing Environmental Contamination exists at the construction site, then Ashland will be obligated to indemnify the Company Indemnified Persons for 50% of the cost of all Remediation Activities relating to such pre- Closing Environmental Contamination, subject to the applicable Individual Threshold Amount; provided, that in no event shall Ashland’s aggregate indemnity obligation with respect to all Claims made under this Section 9.8(j) exceed $2,500,000. Notwithstanding anything to the contrary contained in this Section 9.8(j), neither Marathon nor Ashland shall have any obligation under this Section 9.8(j) or under Section 9.8(n) for Environmental Losses arising from Remediation Activities required in connection with pre-Closing Environmental Contamination identified by the Company during the conduct of construction activities undertaken by the Company on any of the sites identified on Schedule 9.8(n) to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter and Schedule 9.8(n) to the Ashland Asset Transfer and Contribution Agreement Disclosure Letter.

(k) Survival of Environmental Indemnity. The indemnification obligations of Marathon contained in Section 9.1(c) with respect to Environmental Losses (other than Environmental Contamination that is the subject of a Marathon Consent Decree or a Marathon Ongoing Remediation and Marathon Designated UST Environmental Contamination) and the indemnification obligations of Ashland contained in Section 9.2(c) with respect to Environmental Losses (other than Environmental Contamination that is the subject of an Ashland Consent Decree or an Ashland Ongoing Remediation and Ashland Designated UST Environmental Contamination) shall survive for a period of nine years after the Closing (in the event of (i) an Environmental Loss other than a New RCRA Environmental Loss and (ii) a New RCRA Environmental Loss subject to reduction in accordance with column 1 of Section 9.8(e)) or fourteen years after the Closing (in the event of a New RCRA Environmental Loss subject to reduction in accordance with column 2 of Section 9.8(e)) or until the occurrence of a Termination Event with respect to such Environmental Loss, whichever first occurs, in either case reduced pursuant to Section 9.8(e); provided that such obligations shall survive and continue after such period with respect to any Environmental Loss that is Asserted in reasonable detail against Marathon or Ashland, as the case may be, prior to the expiration of such period until the occurrence of a Termination Event. Notwithstanding any other provision of this Article IX, the indemnification obligations of Marathon contained in Section 9.1(c) with respect to Environmental Contamination that is the subject of a Marathon Consent Decree or a Marathon Ongoing Remediation and Marathon Designated UST Environmental Contamination shall survive the Closing and not terminate until the occurrence of a Termination Event. Notwithstanding any other provision of this Article IX, the indemnification obligations of Ashland contained in Section 9.2(c) with respect to Environmental Contamination that is the subject of an Ashland Consent Decree or an Ashland Ongoing Remediation and Ashland Designated UST Environmental Contamination shall survive the Closing and not terminate until the occurrence of a Termination Event. Notwithstanding any other provision of this Article IX, the indemnification obligations of

Marathon or Ashland, as the case may be, contained in Section 9.8(f) and Section 9.8(n) shall survive the Closing and not terminate until the occurrence of a Termination Event. The indemnification obligations of the Company contained in Section 9.3(a) and Section 9.3(e) shall survive the Closing and not terminate. The indemnification obligations of Marathon and Ashland contained in Section 9.8(j) shall survive for a period of ten years after the Closing, reduced pursuant to Section 9.8(e).

(l) Burden of Proof with Respect to Multi-media Audits. Any Claim by the Company relating to a Marathon Environmental Loss or an Ashland Environmental Loss that was identified during the course of an audit conducted after the Closing Date by the National Enforcement Investigation Center of the United States Environmental Protection Agency or any other multi-media environmental inspection by a Governmental Authority and that is Asserted prior to the fifth anniversary of the Closing Date will be presumed to have arisen out of Marathon’s Business or Ashland’s Business, as the case may be, prior to the Closing Date and to be subject to the terms either of the Marathon indemnity under Section 9.1(c) or the Ashland indemnity under Section 9.2(c), as applicable, except to the extent that Marathon or Ashland, as applicable, demonstrates by a preponderance of the evidence that all or part of such Environmental Loss arose out of the Company’s Business on or after the Closing Date.

(m) Compliance with Consent Decrees. The Company shall perform, as necessary, and shall cause its subsidiaries to perform, as necessary, the obligations set forth in the Marathon Consent Decrees and the Ashland Consent Decrees in accordance with the terms thereof and shall cooperate with Marathon or Ashland, as the case may be, in ongoing negotiations related thereto and shall take reasonable action to facilitate the resolution of such negotiations. The Company shall not be entitled to reimbursement from Marathon or Ashland for indirect corporate and administrative overhead costs in performing such obligations. Nothing contained in this Section 9.8(m) is to be construed as in any way limiting the indemnity or other obligations of Marathon contained in Section 9.1(c), Section 9.1(e) or this Section 9.8 or the indemnity or other obligations of Ashland contained in Section 7.2(k), Section 9.2(c), Section 9.2(e) or this Section 9.8.

(n) Potential Future Remediation Activities or Corrective Actions. The Company shall use its commercially reasonable best efforts to (i) avoid taking actions that could reasonably be expected to result in the application or imposition of an Environmental Requirement at the sites set forth on Schedule 9.8(n) to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter or Schedule 9.8(n) to the Ashland Asset Transfer and Contribution Agreement Disclosure Letter, taking into consideration the potential consequences of such Remediation Activities or correction, the magnitude of the potential liability and the operating history of the facility, but not taking into consideration the existence of any indemnity obligation pursuant to this Article IX, and (ii) minimize the scope of any such Remediation Activities or application or imposition. Subject to Section 9.8(g) and the final sentence of Section 9.8(j), in the event that the Company is required by an Environmental Requirement to undertake Remediation Activities or to correct an Environmental Violation at the sites set forth on Schedule 9.8(n) to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter, then Marathon shall be obligated to indemnify the Company for any Marathon Environmental Losses incurred by the

Company in connection therewith to the same extent as if such action were a Marathon Ongoing Remediation. Subject to Section 9.8(g) and the final sentence of Section 9.8(j), in the event that the Company is required by an Environmental Requirement to undertake Remediation Activities or to correct an Environmental Violation at the sites set forth on Schedule 9.8(n) to the Ashland Asset Transfer and Contribution Agreement Disclosure Letter, then Ashland shall be obligated to indemnify the Company for any Ashland Environmental Losses incurred by the Company in connection therewith to the same extent as if such action were an Ashland Ongoing Remediation. Notwithstanding the foregoing, in the event the Company has not used commercially reasonable best efforts to avoid, or minimize the scope of, such Remediation Activities or correction, Marathon or Ashland, as the case may be, will not be obligated to indemnify the Company for any Environmental Losses incurred by the Company or its subsidiaries in connection therewith.

Section 9.9 Employee Matters Indemnification.

(a) Except as provided in the Shared Services Agreement, Marathon shall, from and after Closing, protect, defend, indemnify and hold harmless the Company, Ashland, and the officers, employees, plan administrators, third party administrators, and fiduciaries of the Company and Ashland from any and all Loss suffered as a result of, from, out of or related to:

(i) Actions by Marathon, either prior to or subsequent to Closing, which lead to challenges by the Internal Revenue Service in the form of plan disqualification, a closing agreement or a voluntary compliance resolution program filing on behalf of any Company Employee Benefit Plan.

(ii) Actions by Marathon, either prior to or subsequent to Closing, which lead to the imposition of sanctions on the Company and/or upon any Company Employee Benefit Plan by the Department of Labor, the PBGC, or any other governmental agency, federal or state, with regulatory authority over Employee Benefit Plans.

(iii) Actions by Marathon, either prior to or subsequent to Closing, which lead to the imposition of sanctions upon the Company by any Governmental Authority with regulatory authority over the Company’s payroll and employment practices due to employment practices Marathon pursued prior to the creation of the Company.

(iv) Any lawsuit brought by participants, beneficiaries or fiduciaries against the Company or any Employee Benefit Plan as a result of actions by Marathon affecting an Employee Benefit Plan, either prior to or subsequent to Closing, which results in the imposition of damages upon the Company or a Company Employee Benefit Plan or a plan fiduciary.

(b) Except as provided in the Shared Services Agreement, Ashland shall, from and after Closing, protect, defend, indemnify and hold harmless the Company, Marathon, and the officers, employees, plan administrators, third party administrators, and fiduciaries of the Company and Marathon from any and all Loss suffered as a result of, from, out of, or related to:

(i) Actions by Ashland, either prior to or subsequent to Closing, which lead to challenges by the Internal Revenue Service in the form of plan disqualification, a closing agreement or a voluntary compliance resolution program filing on behalf of any Company Employee Benefit Plan.

(ii) Actions by Ashland, either prior to or subsequent to Closing, which lead to the imposition of sanctions on the Company and/or upon any Company Benefit Plan by the Department of Labor, the PBGC, or any other governmental agency, federal or state, with regulatory authority over Employee Benefit Plans.

(iii) Actions by Ashland, either prior to or subsequent to Closing, which lead to the imposition of sanctions upon the Company by any Governmental Authority with regulatory authority over the Company’s payroll and employment practices due to employment practices Ashland pursued prior to the creation of the Company.

(iv) Any lawsuit brought by participants, beneficiaries or fiduciaries against the Company or any Employee Benefit Plan as a result of actions by Ashland affecting an Employee Benefit Plan, either prior to or subsequent to Closing, which results in the imposition of damages upon the Company or a Company Employee Benefit Plan or a plan fiduciary.

(c) The Company shall, from and after Closing, protect, defend, indemnify and hold harmless Ashland, its officers, employees, plan administrators, third party administrators, and fiduciaries from any and all Losses arising as a result of any action by the Company as part of its participation in any Ashland qualified benefit plan as an adopting employer.

(d) The Company shall, from and after Closing, protect, defend, indemnify and hold harmless Marathon, its officers, employees, plan administrators, third party administrators, and fiduciaries from any and all Losses arising as a result of any action taken by the Company as part of its participation in any Marathon qualified benefit plan as an adopting employer.

(e) For purposes of this Article IX, Loaned Employees shall be deemed to be employees of the Company during the period of their assignment to the Company or its subsidiaries.

Section 9.10 Special Refinery Shutdown Provisions Claims.

(a) The Company shall use its commercially reasonable best efforts to avoid a shutdown of a Marathon Refinery or an Ashland Refinery or a Major Unit thereof for which Marathon or Ashland is obligated to indemnify the Company pursuant to Section 9.1(e) or Section 9.2(e).

(b) In the event that the Company becomes aware of a problem that might reasonably be expected to lead to a shutdown of a Marathon Refinery or a Major Unit thereof for

which Marathon is obligated to indemnify the Company pursuant to Section 9.1(e), the Company shall (A) promptly provide written notice of such problem to Marathon and Ashland, (B) consult with Marathon as to how it intends to resolve such problem and (C) use its commercially reasonable best efforts to resolve such problem in the manner discussed with Marathon and Ashland as promptly as practical and in the most cost effective manner (as reasonably determined by the Company). In the event that the Company becomes aware of a problem that might reasonably be expected to lead to a shutdown of an Ashland Refinery or a Major Unit thereof for which Ashland is obligated to indemnify the Company pursuant to Section 9.2(e), the Company shall (i) promptly provide written notice of such problem to Ashland and Marathon, (ii) consult with Ashland as to how it intends to resolve such problem and (iii) use its commercially reasonable best efforts to resolve such problem in the manner discussed with Ashland as promptly as practical and in the most cost effective manner (as reasonably determined by the Company).

(c) In the event of a shutdown of a Marathon Refinery or Major Unit thereof for which Marathon is obligated to indemnify the Company pursuant to Section 9.1(e), the Company shall (i) immediately provide written notice of such event to Marathon and Ashland, (ii) consult with Marathon as to how it intends to resolve the problems identified by the Governmental Authority in its decision to shutdown the Marathon Refinery or Major Unit thereof, (iii) use its commercially reasonable best efforts to resolve such problems in the manner discussed with Marathon as promptly as practicable and in the most cost effective manner (as is reasonably determined by the Company) and (iv) use its commercially reasonable best efforts to mitigate the amount of Loss incurred by it as a result of such shutdown. In the event of a shutdown of an Ashland Refinery or Major Unit thereof for which Ashland is obligated to indemnify the Company pursuant to Section 9.2(e), the Company shall (A) immediately provide written notice of such event to Marathon and Ashland, (B) consult with Ashland as to how it intends to resolve the problems identified by the Governmental Authority in its decision to shut down the Ashland Refinery or Major Unit thereof, (C) use its commercially reasonable best efforts to resolve such problems in the manner discussed with Ashland as promptly as practicable and in the most cost effective manner (as is reasonably determined by the Company) and (D) use its commercially reasonable best efforts to mitigate the amount of Loss incurred by it as a result of such shutdown.

Section 9.11 Sole and Exclusive Remedy. (a) Each of the parties acknowledges and agrees that, should the Closing occur, the parties’ sole and exclusive remedies with respect to any and all Claims relating to this Agreement, the Master Formation Agreement and the other Conveyance Documents and the transactions contemplated hereby and thereby (other than Claims of, or causes of action arising from, (i) the covenants to be performed post-Closing related to this Agreement, the Master Formation Agreement and the other Conveyance Documents and the transactions contemplated hereby and thereby (other than covenants in the Sublease Agreements), (ii) the other Transaction Documents, (iii) the Commercial Documents or (iv) fraud) shall be pursuant to the indemnification provisions set forth in this Article IX. In furtherance of the foregoing, each of the parties hereto hereby waives, from and after the Closing, any and all rights, Claims and causes of action relating to this Agreement, the Master Formation Agreement and the other Conveyance Documents and the transactions contemplated hereby and thereby (other than Claims of, or causes of action arising from, (i) the covenants to be performed post-Closing related to this Agreement, the Master Formation Agreement and the other

Conveyance Documents and the transactions contemplated hereby and thereby (other than covenants in the Sublease Agreements), (ii) the other Transaction Documents, (iii) Commercial Documents or (iv) fraud) it may have against the other parties hereto arising under or based upon Applicable Law (except pursuant to the indemnification provisions set forth in Article IX and the provisions of Appendix B). In the event that the Closing does not occur, the parties each shall have all remedies available under Applicable Law, subject to the provisions of Section 7.5(a), Section 7.6(a), Article VIII, Section 9.10 and Section 9.17 of the Master Formation Agreement and subject to the provisions of Section 9.14(a), Section 9.15(a), Section 11.8 and Section 11.15.

(b) Each of the parties acknowledges and agrees that with respect to any and all Claims relating to (i) the covenants to be performed post-Closing related to this Agreement, the Master Formation Agreement and the other Conveyance Documents and the transactions contemplated hereby and thereby (other than covenants in the Sublease Agreements), (ii) the other Transaction Documents, (iii) the Commercial Documents and (iv) fraud, the parties each shall have all remedies available under Applicable Law, subject to the provisions of Section 11.8 and Section 11.15.

(c) Marathon and Ashland acknowledge that, while the Company is expected in most circumstances to be the primary beneficiary of indemnification Claims, each of them may also have a Claim against the other under Article IX. It is intended, however, that the Company shall have the primary Claim for indemnity in any matter related to the property, assets and liabilities of the Company and its subsidiaries and that Marathon and Ashland shall be entitled to indemnification compensation only to the extent either of them or any of their respective Affiliates (other than the Company or any of its subsidiaries) suffers a direct Loss or Claim, as opposed to indirect harm, as a result of Losses or Claims with respect to the Company’s Business.

Section 9.12 Losses Net of Insurance, Etc. The amount of any Loss shall be net of any amounts actually recovered by the Indemnified Party under the True Insurance Policies with respect to such Loss and shall be (i) increased to take account of any net Tax cost incurred by the Indemnified Party arising from the receipt or accrual of indemnity payments hereunder (grossed up for such increase) and (ii) reduced to take account of any net Tax Benefit realized by the Indemnified Party arising from the deductibility of any such Loss. In computing the amount of any such Tax cost or Tax Benefit, the Indemnified Party shall be deemed to recognize all other items of income, gain, loss, deduction or credit before recognizing any item arising from the receipt or accrual of any indemnity payment hereunder or the deductibility of any indemnified Loss. Any indemnification payment hereunder shall initially be made without regard to this Section 9.12 and shall be increased or reduced to reflect any such net Tax cost (including gross-up) or net Tax Benefit only after the Indemnified Party has actually realized such cost or benefit. For purposes of this Agreement, an Indemnified Party shall be deemed to have “actually realized” a net Tax cost or a net Tax Benefit to the extent that, and at such time as, the amount of Taxes payable by such Indemnified Party is increased above or reduced below, as the case may be, the amount of Taxes, that such Indemnified Party would be required to pay but for the receipt or accrual of the indemnity payment or the deductibility of such Loss, as the case may be. The amount of any increase or reduction hereunder shall be adjusted to reflect any final determination (which shall include the execution of Form 870- AD or successor form) with respect to the

Indemnified Party’s liability for Taxes, and payments between the Indemnified Party and the Indemnifying Party to reflect such adjustment shall be made if necessary.

Section 9.13 Additional Provisions. Notwithstanding any other provisions of this Article IX, but subject to Section 9.8(c) and Section 9.11, Marathon, Ashland and the Company and their respective Affiliates shall each be entitled, as a purchaser or seller of product or provider or recipient of services, to enforce its rights and remedies against the other pursuant to separate contractual arrangements, including the Commercial Documents.

Section 9.14 Waiver of Punitive and Consequential Damages.

(a) Pre-Closing Waiver. Notwithstanding anything to the contrary contained in any other provision of this Agreement, in the event that the Closing does not occur, neither Marathon nor Ashland shall be required to indemnify, or be liable to, the other party, the Company or any of their respective Affiliates for punitive damages.

(b) Post-Closing Waiver. Notwithstanding anything to the contrary contained in any other provision of this Agreement, in the event that the Closing occurs, neither Marathon nor Ashland shall be required to indemnify the other party hereunder, the Company or any of their respective Affiliates for any indirect, consequential, special, exemplary or punitive damages except for (i) loss of profit to the extent provided in Section 9.1(e) and Section 9.2(e), (ii) consequential damages arising out of a breach by the Company of its covenants in Section 7.3(d) or in any of the Marathon Sublease Agreements or Ashland Sublease Agreements, as applicable, and (iii) indirect, consequential, special, exemplary or punitive damages actually paid to any third party by the Indemnified Party seeking indemnity hereunder.

Section 9.15 Dispute Resolution. (a) Resolution of Disputes Pre-Closing. All Disputes arising prior to the Closing that relate to this Agreement shall be resolved solely pursuant to Sections 1, 2 and 3 of Appendix B.

(b) Resolution of Disputes Post-Closing. In the event that the Closing occurs, all Disputes relating to this Agreement (and, unless otherwise provided therein, in the Commercial Documents) shall be resolved solely pursuant to Appendix B (other than Section 3 thereof); provided, however, that disputes under Section 4.3, Section 4.4 and Section 7.2(g) shall be governed by the dispute resolution procedures contained therein. The parties recognize that the Company may be deemed to be an Affiliate of Ashland and Marathon. Accordingly, in any dispute between the Company and Marathon, Ashland may elect to represent the Company’s interest and in any dispute between the Company and Ashland, Marathon may elect to represent the Company’s interest.

Section 9.16 Good Faith Pursuit of Claims and Fair Treatment. In pursuing Claims for indemnification hereunder, the Company shall act in good faith and shall treat Marathon and Ashland fairly (including decisions with respect to whether to pursue a Claim and the pursuit of such Claim) with respect to all such Claims. The Company shall also use best efforts that are (i) consistent with reasonable commercial practices and (ii) prudently protective of

human health and the environment in light of all known and reasonably suspected facts and conditions to assure the fair and equitable treatment of Marathon and Ashland with respect to all matters that are the subject of this Article IX.

ARTICLE X

EMPLOYEE MATTERS

Section 10.1 Loan of Employees.

(a) Designation. On or before the day prior to the Closing Date, Marathon and Ashland will designate which employees or employee groups will be loaned to the Company or its subsidiaries (such employees or employee groups, together with any other employees or employee groups thereafter designated by Marathon and Ashland as employees or employee groups to be loaned to the Company or its subsidiaries, the “Loaned Employees”). Except as otherwise required pursuant to any collective bargaining agreement, employees who are on any type of leave on the day prior to the Closing Date, except ordinary sick leave reasonably expected to be of a duration not to exceed 30 days or a leave under the Family and Medical Leave Act, shall not be eligible for loan until they have returned from such leave to resume their regular work duties. After it is determined which of their employees will be loaned to the Company, Marathon and Ashland shall make available to the Company such information as they shall from time to time agree to provide.

(b) Effective Date and Effect of Loan. Employees or employee groups who are designated as Loaned Employees by the day prior to the Closing Date under Section 10.1(a) shall be loaned to the Company effective on the Closing Date for such period as identified under Section 10.1(c). Additional employees who are designated as Loaned Employees after the day prior to the Closing Date under Section 10.1(a) shall be loaned to the Company effective on the date they first perform services for the Company. For purposes of this Article X, “Employer Company” shall mean Marathon or Ashland, depending on who designated an employee as a Loaned Employee. Subject to overall direction of the Company’s management, the Employer Company shall retain control over the time, manner and method of employment of its Loaned Employees who shall be considered common-law employees of the respective Employer Companies.

(c) Period of Loan. Unless agreed otherwise by Marathon and Ashland, the period for which the Loaned Employees are assigned to the Company shall end:

(i) No later than April 1, 1998 for non-retail segments of the Company except for shared service and certain administrative employees who may be loaned longer; and

(ii) No later than December 31, 1998 for retail employees.

At the end of the Loaned Employee’s period of loan which in no event shall extend beyond December 31, 1998, such Loaned Employee shall, if not transferred to employment with the Company, remain subject to his/her Employer Company’s employment policies as from time to time in effect. Loaned employees who are transferred to the employment with the Company from Marathon are hereinafter referred to as “Marathon Transferred Employees”. Loaned employees who are transferred to employment with the Company from Ashland are hereinafter referred to as “Ashland Transferred Employees”. The date of a Loaned Employee’s transfer to employment with the Company is referred to as “Employment Transfer Date.”

(d) Costs of Loaned Employees. Marathon and Ashland shall charge to the Company their respective costs for their respective Loaned Employees. Each Employer Company shall determine the amount for this charge based on the method it ordinarily employs for allocating costs for salary, wages and employee benefit plans and related administrative expenses to its divisions, business units and subsidiaries. The Company and each Employer Company will be entitled, upon request, to receive a reasonable explanation of the methodology a particular Employer Company employs to charge the costs related to its Loaned Employees to the Company. Amounts determined pursuant to this Section 10.1(d) shall be charged to the Company at such times and using such procedures as Marathon, Ashland and the Company shall agree upon. The time, manner and method of allocating costs under this Section 10.1(d) may be changed, from time to time, upon the agreement of Marathon, Ashland and the Company.

(e) Xxxxxxxx Permian Canadian Employees. The employees of Xxxxxxxx Permian, a subsidiary of Ashland, who are in Canada shall be included in the group of employees who are loaned pursuant to the provisions of this Section 10.1 and shall be subject to all the other provisions hereto that apply to them. Effective as of the date the period of loan ends for these employees pursuant to the provisions of Section 10.1(c), these employees shall go out of coverage under the plans in Canada then covering them. Whatever pension and other retirement benefits earned through the Employment Transfer Date shall be retained by the Canadian plans of Ashland and these employees shall then be eligible to participate in the benefit plans offered to them by the Company.

Section 10.2 Certain Employee Positions and Shared Services.

(a) Position Offers. (i) Marathon and Ashland agree that initial offers of positions in the Company will be made to Persons as set forth in Schedule 10.2(a) to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter.

(ii) Following the date of this Agreement and until an organizational structure for all operations of the Company other than retail operations is finalized, the Company Best Practices Committee, which has been constituted prior to the date of this Agreement, will continue to recommend an organizational structure for the Company and report to and recommend staffing for such operations to the Board of Managers. All such reports and recommendations will be premised upon the most effective operation of the Company as a whole, and the initial offers of positions to remaining management and staff of the Company, excluding non-exempt and hourly employees, will be allocated between

former Marathon and Ashland employees in approximate proportion to the respective ownership interests in the Company of Marathon and Ashland to the extent qualified candidiates are available, taking into account employees who have turned down positions offered and employees who have been transferred since May 15, 1997 by Ashland or Marathon or their respective Affiliates out of the Ashland Business or the Marathon Business, respectively, prior to receiving an offer of employment.

(iii) Following the date of this Agreement and until an organizational structure for retail operations is finalized, the Retail Operations Best Practices Committee, which has been constituted prior to the date of this Agreement, will report to the Board of Managers through the Company President and will continue to recommend staffing for the retail business of the Company. All such reports and recommendations will be premised upon the most effective operation of the Company as a whole, and the initial offers of positions to remaining management and staff located at Enon, Ohio and Lexington, Kentucky, excluding non-exempt and hourly staffing, will be allocated between former Marathon and Ashland employees in approximate proportion to the respective ownership interests in the Company of Marathon and Ashland to the extent qualified candidates are available, taking into account employees who have turned down positions offered and employees who have been transferred since May 15, 1997 by Ashland or Marathon or their respective Affiliates out of the Ashland Business or the Marathon Business, respectively, prior to receiving an offer of employment. All other retail operations staffing above store level will be determined through the Retail Operations Best Practices Committee process described above, subject to the mutual agreement of Marathon and Ashland.

(b) Initial Locations of Management and Staff. Marathon and Ashland agree that:

(i) Headquarters of the Company will be in Findlay, Ohio, and all persons filling senior management positions of the Company except retail senior management positions, will be relocated as necessary to Findlay, Ohio, during the period of integration of operations of the Company following the Closing Date.

(ii) Lower level management and staff of the Company (except retail management and staff) will initially be located at both Findlay, Ohio and Ashland, Kentucky. In this connection, the initial expected level of staffing in Ashland, Kentucky is set forth on Schedule 10.2(b) to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter. Subject to changes in staffing approved by the Board of Managers, the Company intends to maintain a significant employment presence in Ashland, Kentucky, having due regard for Ashland’s sensitivity to this matter. The Company shall give reasonable notice, and in any event not less than sixty (60) days’ prior written notice, to each Member, of any decision to terminate ten (10) or more employees located in Ashland, Kentucky or to relocate ten (10) or more employees located in Ashland, Kentucky to other Company locations, treating a series of related decisions (whether to terminate or relocate or both) as one decision.

(c) Relocation Costs. During the period of integration of the Company’s operation, certain Loaned Employees and Company employees will need to be relocated. Marathon and Ashland agree that all costs of relocation incurred for any Loaned Employee or employee of the Company designated for relocation during such period of integration not to extend beyond June 30, 1999 shall be borne 50% by Marathon and 50% by Ashland and that in the event any such costs are actually paid by the Company shall be promptly reimbursed 50% by Marathon and 50% by Ashland.

(d) Severance Arrangements.

(i) Marathon and Ashland agree that they will each establish severance arrangements or special severance plans for employees whose employment has been identified as redundant or otherwise not required during and after the integration phase of operations of the Company, with the understanding that former employees of Marathon and Ashland will be treated as nearly equal as possible, considering salary and service differences. The Company will adopt a special severance plan substantially similar to the severance arrangements or plans of Marathon and Emro for employees of Marathon Ashland Pipe Line LLC, Speedway SuperAmerica LLC and Speedway Beverage LLC. Such severance plans or arrangements shall cover employees at least down to, but not necessarily including, non-exempt employees. Marathon, Ashland and the Company agree that the severance plans set forth on Schedule 10.2(d) to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter and on Schedule 10.2(d) to the Ashland Asset Transfer and Contribution Agreement Disclosure Letter are deemed to be substantially similar to such severance arrangements or plans of Marathon and Ashland, respectively, for purposes of this Agreement.

(ii) Persons who have formerly been employed in connection with Marathon’s Business and Ashland’s Business, including Loaned Employees, and who have been identified as redundant will not be offered employment with the Company (except employees of Marathon Pipe Line and Emro). Any Person who becomes an employee of the Company (other than employees of Marathon Pipe Line and Emro) will not be eligible for the severance arrangements described in this Section 10.2(d) and the Company will assume responsibility for any severance of its employees (other than employees of Marathon Pipe Line and Emro).

(iii) Each of Marathon and Ashland shall be responsible for all severance costs (which may include arbitration and/or litigation) with respect to the former employees of Marathon’s Business and Ashland’s Business, respectively, for any employees who are terminated during the integration phase of the Company’s Business. Any such severance costs for employees of Marathon Pipe Line and Emro will be reimbursed to the Company by Marathon.

(e) Shared Services. Marathon and Ashland agree that certain administrative staff functions will be supplied to the Company on a shared service basis by Marathon or Ashland

(and not by Loaned Employees) as set forth on Schedule 10.2(e) to the Marathon Asset Transfer and Contribution Agreement Disclosure Letter or Schedule 10.2(e) to the Ashland Asset Transfer and Contribution Agreement Disclosure Letter, as the case may be, upon the completion of the integration process within each such function. In addition, certain of these shared services and certain other shared services may be supplied by Marathon or Ashland to the Company during the period of integration of the Company’s operations as provided in the Shared Services Agreement. The provision of such services will be supplied pursuant to the Shared Services Agreement. From the Closing through March 31, 1998, or until such later time as the Company and the applicable shared service provider shall agree, the cost of such services and any additional corporate and administrative services provided to the Company will be consistent with the costing methodologies Marathon and Ashland used in establishing Historical EBITDA (as defined in the LLC Agreement). Beginning April 1, 1998, or until such later time as the Company and the applicable shared service provider shall agree, the costing methodologies to be used by Marathon and Ashland for providing such services will be mutually agreed upon after Closing and set forth in the schedules to the Shared Services Agreement. In the event of any conflict between the provisions of this Agreement and the LLC Agreement, on the one hand, and the provisions of Schedule 10.2(e), on the other hand, the provisions of this Agreement and the LLC Agreement shall control.

Section 10.3 General. The Company shall establish such benefit plans and practices for the benefit of Marathon Transferred Employees and Ashland Transferred Employees as it shall determine; provided, however, such plans and practices established by the Company shall be consistent with the terms of this Agreement and such other agreements, collective bargaining or otherwise, as may be applicable to the Company. Except as otherwise provided in this Agreement, it is understood that the Company will have full authority to amend, merge with another plan, modify, terminate or take any other action it deems appropriate or desirable with respect to all plans its sponsors and all employment practices it adopts.

Section 10.4 Collective Bargaining Agreements. Marathon, Ashland and the Company agree to use good faith reasonable efforts to obtain the consent of all appropriate Marathon and Ashland OCAW locals as well as Teamsters Local 120 at the Northwestern Refinery and any other Teamsters Local not participating in the Teamsters Pension Plan to the benefit plan package and other relevant matters to be applicable to the members thereof including, where applicable, the disabled, inactive or retired employees who were members of such bargaining unit. Marathon, Ashland and the Company agree to cooperate with each other to obtain such consents on conditions and understandings that are acceptable to Marathon, Ashland and the Company. In the case of any Teamsters Local covered by the Teamsters Pension Plan, Marathon, Ashland and the Company agree to use good faith reasonable efforts to obtain any consents deemed by the Company to be appropriate.

Section 10.5 The Non-Retail DB Plan. Marathon shall cause a plan to be spun off from the Retirement Plan of Marathon Oil Company (the “Marathon Retirement Plan”) which spun off plan will be amended and restated by the Company and become the primary defined benefit plan for non-retail Company employees not participating in other Company defined benefit plans (the “Non-Retail DB Plan”). The “Non-Retail DB Plan” shall be tax qualified under

Section 401(a) of the Code and its trust shall be exempt from tax under Section 501(a) of the Code. Unless otherwise agreed by Marathon and Ashland, the initial spin-off of assets and liabilities shall be implemented as soon as administratively feasible after April 1, 1998.

(a) Transfer of Assets and Liabilities to the Non-Retail DB Plan. As soon as practicable after the Employment Transfer Date for Marathon Transferred Employees (the “Marathon Pension Transfer Date”), but no earlier than 30 days following the filing of Form 5310-A with the Internal Revenue Service, Marathon shall cause to be transferred: (i) from the Marathon Retirement Plan to the Non-Retail DB Plan, the accrued benefits liability as of the Marathon Pension Transfer Date of each of the former employees of Marathon who are hired by the Company (“Former Marathon Plan Participants”) who participated in the Marathon Retirement Plan prior to the Marathon Pension Transfer Date, and (ii) from the trust relating to the Marathon Retirement Plan to the trust of the Non-Retail DB Plan, an undivided interest in the master trust currently holding Marathon Retirement Plan assets as mutually agreed upon by Marathon and Ashland (which agreement shall not be unreasonably withheld by either party) equal to a fraction of the total actual assets of the Marathon Retirement Plan as of the Marathon Pension Transfer Date. The numerator of such fraction is the projected benefit obligation (“PBO”) of the Former Marathon Plan Participants as of the Marathon Pension Transfer Date, and the denominator is the PBO of all participants in the Marathon Retirement Plan as of the Marathon Pension Transfer Date. For purposes of the preceding sentence, the PBO shall be determined on the basis of each employee’s age, service and compensation, and the terms of the Marathon Retirement Plan in effect on the Marathon Pension Transfer Date, using:

(i) the 30-year Treasury rate plus 100 basis points rounded to the nearest one-half (½) percent for the discount rate;

(ii) the lump sum rate shall be 200 basis points less than the discount rate used;

(iii) the salary scale used in determining the accrued benefits liability shall be an average annual rate that approximates 5%; and

(iv) for all other actuarial assumptions and methods the same as are used for SFAS No. 87 disclosures for the year ended December 31, 1997.

The amount of assets to be transferred pursuant to the preceding sentence shall be increased or decreased by the actual return on the market value of assets from the Marathon Pension Transfer Date to the date of transfer and decreased by the amount of any benefit payments to Former Marathon Plan Participants occurring subsequent to the Marathon Pension Transfer Date and prior to the date of transfer. After completion of the transfer of all liabilities and assets for the applicable Transferred Marathon Employees moved from the Marathon Retirement Plan to the Non-Retail DB Plan, the Marathon Retirement Plan shall have no further obligation for the payment of pension benefits to these individuals. In no event will the amount to be transferred be less than is required under Sections 401(a)(12) and 414(l) of the Code. The parties have mutually

agreed that the United States Steel and Carnegie Pension Fund shall initially be the trustee for the Non-Retail DB Plan.

(b) Additional Transfers of Marathon Employees or Employee Groups. Additional spinoffs from the Marathon Retirement Plan may take place during the 1998 plan year if other Marathon employees who participated in the Marathon Retirement Plan become employees of the Company after January 1, 1998 but prior to January 1, 1999. Such spinoffs shall follow the provisions of Section 10.5(a).

(i) The Non-Retail DB Plan shall provide that in calculating the benefit payable to a participant in the Non-Retail DB Plan who was an Ashland Transferred Employee participating in the Ashland Inc. and Affiliates Pension Plan (“Ashland Pension Plan”), the Non-Retail DB Plan shall include such Ashland Transferred Employee’s benefit accrual service as of his/her Transfer Date under the Ashland Pension Plan. The benefit thus determined under the Non-Retail DB Plan, (in a single life annuity form using such Plan’s discounts for commencement of benefits before the normal retirement age under such Plan), shall be reduced by the Ashland Transferred Employee’s benefit under the Ashland Pension Plan (the benefit payable under the Ashland Pension Plan shall be determined at the particular date after the Transfer Date in a single life annuity form and recognizing benefit accrual service under the Non-Retail DB Plan on or after the date of transfer to the Non- Retail DB Plan for the purposes of determining eligibility and vesting but not for the purpose of accrual of benefits under the Ashland Pension Plan, also assuming that the Ashland LESOP did not exist and that any other offsets provided under the Ashland Pension Plan relating to benefits payable from predecessor or foreign plans be ignored); provided, however, the net benefit payable under the Non-Retail DB Plan shall not be less than what the Ashland Transferred Employee would have earned under the Non-Retail DB Plan using only benefit accrual service thereunder from such Employee’s Transfer Date. In the event that an employee commences a benefit under the Non-Retail DB Plan prior to age 55 and if such employee is not eligible for the early retirement discounts under the Ashland Pension Plan, the offset will be based on the Ashland Pension Plan’s age 55 single life annuity deferred vested factor adjusted actuarially for an earlier age of benefit commencement. The operation of this paragraph is illustrated in Appendix C.

(ii) Ashland, in its own Ashland Pension Plan, will retain the ABO benefits (accumulated benefit obligations as defined under Statement of Financial Accounting Standards No. 87) for the Ashland Transferred Employees at the Ashland Employee Transfer Date, and will continue to recognize service with the Company for purposes of determining eligibility for benefits and vesting service, but not for purposes of accrual of benefits, for the Ashland Transferred Employees.

100

(iii) In the event that an Ashland employee transfers to the Company after December 31, 1998, such individual’s benefit under the Non-Retail DB Plan will take into account prior service with Ashland, with the offset for benefits accrued under the Ashland Pension Plan determined at the time of their transfer to the Company and calculated as provided in paragraphs (i) and (ii) above.

(iv) In the event that a Marathon employee transfers to the Company after December 31, 1998, such individual’s benefit under the Non-Retail DB Plan will take into account prior service with Marathon, with the offset for benefits accrued under the Marathon Plan determined at the time of their transfer to the Company and calculated in a manner similar to paragraphs (i) and (ii) above taking into account the provisions of the Marathon Plan. The operation of this paragraph is illustrated in Appendix C.

(d) The dollar amount of assets transferred from the Marathon Retirement Plan to the Non-Retail DB Plan shall be determined and certified to by Marathon’s actuaries. This determination shall be subject to review and confirmation by Ashland’s actuaries. Marathon shall cause its independent public accountants to certify that they have tested the data provided to its actuaries and have concluded that such data is correct and complete, with the scope of the audit mutually agreed upon by Marathon, Ashland and the Company. Marathon shall provide audited data to Ashland’s actuaries within a reasonable time after the former Marathon Retirement Plan participants have been designated. Marathon and Ashland shall reasonably cooperate in the gathering of necessary data to be used by their respective actuaries. Substantially the same procedure shall be used in the event additional spin offs of assets and liabilities occur during 1998.

(e) In all other respects, the Non-Retail DB Plan shall be designed, implemented and subject to such terms as the Company shall from time to time institute through properly enacted provisions.

Section 10.6 Assumption of Petroleum Marketing Retirement Plan and Benefit Calculation for Retail Employees Who Formerly Participated in the Ashland Pension Plan.

(a) Assumption of Plan. Speedway SuperAmerica LLC shall assume, as the new plan sponsor and administrator, the responsibilities of the operation, administration and funding of the Petroleum Marketing Retirement Plan (the “PMRP”). In connection with such assumption, Marathon represents and warrants that the PMRP is tax qualified under Section 401(a) of the Code and is and has been operating in substantial compliance with all applicable requirements of the Code and ERISA through the date on which Speedway SuperAmerica LLC assumes the duties of plan sponsor and administrator thereof. Unless otherwise agreed by Marathon and Ashland, such assumption shall occur as of the Closing Date.

(b) Ashland Transferred Employees who are assigned to the retail operations of the Company and who are participants in the Ashland Pension Plan will be given credit for past service with Ashland for all purposes (including benefit accrual) regarding the determination of retirement benefits under any defined benefit plan which is established by the Company or its

101

subsidiaries for retail employees subject to an offset for benefits accrued under the Ashland Pension Plan up to the Transferred Employees’ Employment Transfer Date.

Section 10.7 Spinoff of Freedom Refinery Participants and Assumption of Ashland Retirement Plan.

(a) Spinoff of Assets and Liabilities in Respect of Freedom Refinery Participants from the Retirement Plan of Ashland (“Ashland Retirement Plan”) to a New Defined Benefit Plan to be Retained by Ashland. As soon as practicable after the Employment Transfer Date for the Ashland Transferred Employees (the “Retirement Pension Transfer Date”), but no earlier than 30 days following the filing of Form 5310-A with the Internal Revenue Service, Ashland shall cause to be transferred (i) from the Ashland Retirement Plan to a new defined benefit plan (the “Freedom Pension Plan”) the accrued benefits liability as of the Retirement Pension Transfer Date of each of the union employees (including terminated and retired employees with vested benefits under the Ashland Retirement Plan) of Ashland who are (or were) employed at Ashland’s Freedom, Pennsylvania facility who participated in the Ashland Retirement Plan on the Retirement Pension Transfer Date (“Freedom Employees”) and (ii) from the trust relating to the Ashland Retirement Plan to the new trust relating to the new Freedom Pension Plan an amount equal to a fraction of the total actual market value of assets of the Ashland Retirement Plan determined as of the Retirement Pension Transfer Date. The numerator of such fraction is the PBO of the Freedom Employees as of the Retirement Pension Transfer Date and the denominator is the PBO of all participants in the Ashland Retirement Plan as of the Retirement Pension Transfer Date. For purposes of the preceding sentence, the PBO shall be determined on the basis of each employee’s age, service and compensation, and the terms of the Ashland Retirement Plan in effect on the Retirement Pension Transfer Date using:

(i) the 30-year Treasury rate plus 100 basis points rounded to the nearest one-half (½) percent for the discount rate;

(ii) to the extent applicable, the lump sum rate shall be 200 basis points less than the discount rate used;

(iii) the salary scale used in determining the accrued benefits liability shall be 5%; and

(iv) for all other actuarial assumptions and methods the same as are used for SFAS No. 87 disclosures for the year ended September 30, 1997.

The dollar amount determined in the preceding sentence shall be increased or decreased by the actual return on the market value of assets, and decreased by the amount of benefit payments for the participants in the new Freedom Pension Plan occurring subsequent to Retirement Pension Transfer Date and prior to the date of transfer. In no event shall the amount to be transferred be other than the amount required under Sections 401(a)(12) and 414(l) of the Code.

102

(b) The dollar amount of assets transferred from the Ashland Retirement Plan to the new Freedom Pension Plan shall be determined and certified by Ashland’s actuaries. This determination shall be subject to review and confirmation by Marathon’s actuaries. Ashland shall cause its independent public accountants to certify that they have tested the data provided to its actuaries and have concluded that such data is correct and complete, with the scope of the audit mutually agreed upon by Marathon, Ashland and the Company. Ashland shall provide audited data to Marathon’s actuaries within a reasonable time after the Retirement Pension Transfer Date. Marathon and Ashland shall reasonably cooperate in the gathering of necessary data to be used by their respective actuaries.

(c) Assumption of Plan after Spinoff. Following the spinoff referred to in Section 10.7(a), the Company shall assume, as the new plan sponsor and administrator, the responsibilities of the operation, administration and funding of the Ashland Retirement Plan. In connection with such assumption, Ashland represents and warrants that the Ashland Retirement Plan is tax qualified under Section 401(a) of the Code and is and has been operating in substantial compliance with the applicable requirements of the Code and ERISA through the date on which the Company assumes the duties of plan sponsor and administrator thereof. Unless otherwise agreed by Marathon and Ashland, such assumption shall occur upon the Employment Transfer Date or upon a reasonable date thereafter.

(d) Within a reasonable time following the Employment Transfer Date for Ashland Transferred Employees participating in the Ashland Retirement Plan, the Company shall appoint a successor trustee to the assumed Ashland Retirement Plan and Ashland shall cause the present trustee to transfer to such successor trustee (and the Company shall cause such successor trustee to accept) in cash or other property mutually agreed upon by Marathon and Ashland the assets of the Ashland Retirement Plan.

Section 10.8 Assumption of Northwestern Refinery Pension Plan.

(a) Assumption of Plan. The Company shall assume, as the new plan sponsor and administrator, the responsibilities of the operation, administration and funding of the Northwestern Refinery Pension Plan.

Unless otherwise agreed by Marathon and Ashland, such assumption shall occur upon the Employment Transfer Date or upon a reasonable date thereafter.

(b) Within a reasonable time following the Employment Transfer Date for Ashland Transferred Employees participating in the Northwestern Refinery Pension Plan, the Company shall appoint a successor trustee to the assumed Northwestern Refinery Pension Plan and Ashland shall cause the present trustee to transfer to such successor trustee (and the Company shall cause such successor trustee to accept) in cash or other property mutually agreed upon by Marathon and Ashland the assets of the Northwestern Refinery Pension Plan.

Marathon, Ashland and the Company agree to all of the following with respect to the Central States Southeast and Southwest Areas Pension Fund (the “Teamster Pension Fund”) and the employees who are members of Teamsters Locals 236, 135 and 114 who are eligible for participation in the Teamster Pension Fund (the “Teamster Member Employees”):

(i) Contribution. The Company shall contribute to the Teamster Pension Fund for substantially the same number of contribution base units for which Ashland has an obligation to contribute to the Teamster Pension Fund for the employees who are members of Teamster Locals 236, 135 and 114 on the day prior to Closing.

(ii) Bond. The Company shall provide to the Teamster Pension Fund for a period of five plan years commencing with the first plan year for the Teamster Pension Fund beginning after the Transfer Date for Teamster Member Employees a bond issued by a corporate surety company acceptable for surety purposes under Section 412 of ERISA or an amount held in escrow by a bank or similar financial institution satisfactory to the Teamster Pension Fund in an amount equal to the greater of (i) the average annual contribution required to be made by Ashland for the three plan years preceding the plan year in which the Closing Date occurs, or (ii) the annual contribution Ashland was required to make to the Teamster Pension Fund for the last plan year before the plan year in which the Closing Date occurred, and the bond or escrow relating to the Teamster Pension Fund shall be paid thereto if the Company withdraws from the Teamster Pension Fund or fails to make a contribution thereto when due at any time during the first five plan years beginning after the plan year in which the Employment Transfer Date for Teamster Member Employees occurs.

(iii) Consequence of Withdrawal. If the Company withdraws in a complete or partial withdrawal from the Teamster Pension Fund during the first five plan years beginning after the plan year in which the Employment Transfer Date for Teamster Member Employees occurs, Ashland agrees to be secondarily liable for any withdrawal liability it would have had to the Pension Fund, but for the operation of this provision, if the withdrawal liability of the Company is not paid.

(iv) The Company and Ashland shall take all other action which may be required under Section 4204 of ERISA.

(b) Marathon Employees. The Company will assume Marathon’s obligations under the multiemployer Teamsters Pension Fund for members of Teamsters Local 283 at the Detroit Refinery, Local 283 at the Detroit Terminal and Local 89 at the Louisville Terminal.

(a) Adoption. Marathon agrees it shall take all actions necessary and convenient to designate the Company as a participating employer under the Marathon Oil Company Thrift Plan (the “Marathon Thrift Plan”) for non-Retail employees effective as of April 1, 1998. In connection with such designation of the Company as a participating employer, Marathon represents and warrants that the Marathon Thrift Plan is tax qualified under Section 401(a) of the Code and is and has been operating in substantial compliance with all the applicable requirements of the Code and ERISA as of the date hereof.

(b) Transfers from Ashland Savings Plan. Marathon and the Company agree that the provisions of the Marathon Thrift Plan shall allow each Ashland Transferred Employee who becomes eligible to participate in the Marathon Thrift Plan to transfer the entirety of his or her account balance in the Ashland Inc. Employee Savings Plan, if any, by means of a voluntary elective transfer, as described in Treas. Reg. §1.411(d)-4( Q&A 3(b)), as provided under the applicable terms of the Ashland Inc. Employee Savings Plan, or to transfer all or any part of such account balance, pursuant to terms in the Ashland Inc. Employee Savings Plan, which constitutes an eligible rollover distribution, as defined in Section 402(c) of the Code provided such rollover meets the terms of the Marathon Thrift Plan.

(i) Notwithstanding anything to the contrary contained in the foregoing, the Marathon Thrift Plan will not accept any in-kind transfers of any investment option which is not offered by the Marathon Thrift Plan as part of any such elective transfer or eligible rollover. The Marathon Thrift Plan may impose such other restrictions on such transfers or rollovers as are consistent with requirements for the same under the Code and applicable regulations.

(ii) Such transfers (but not rollovers) will include the amount of any loan to the Ashland Transferred Employee and its related promissory note under the Ashland Inc. Employee Savings Plan that remains outstanding at the time of such transfer, provided that the loan has a term of five years or less and is in good standing. The Marathon Thrift Plan shall allow the remaining amount due to be repaid by the end of the original repayment period pursuant to applicable plan terms and consistent with applicable law.

(iii) It is understood that Marathon retains full authority to amend, merge with another plan, modify, terminate or take any other action it deems appropriate or desirable with respect to the Marathon Oil Company Thrift Plan. It is also understood that the Company may elect to spin off accounts attributable to its employees who are participants therein to a separate defined contribution plan.

Section 10.11 Assumption of Emro Marketing Company Retirement Savings Plan. The Company, or a subsidiary or affiliate of the Company, shall assume, as the new plan sponsor and administrator, the responsibilities of the operation, administration and funding of the Emro Marketing Company Retirement Savings Plan (the “Emro Savings Plan”). In connection with such assumption, Marathon represents and warrants that the Emro Savings Plan is tax qualified under Section 401(a) of the Code and is and has been operating in substantial

105

compliance with all applicable requirements of the Code and ERISA through the date on which the Company assumes the duties of plan sponsor and administrator thereof. Such assumption shall occur as of the Closing Date or such other date as may be agreed upon by Marathon and Ashland.

Section 10.12 Assumption of Permian Corporation Retirement and Savings Plans. The Company, or a subsidiary or Affiliate of the Company, shall assume from Ashland, as the new plan sponsor and administrator, the responsibilities of the operation and administration of the frozen Permian Corporation Retirement Plan and the frozen Permian Corporation Savings Plan (the “Permian Plans”). In connection with such assumption, Ashland represents and warrants that the Permian Plans are tax qualified under Code § 401(a) and are and have been operating in substantial compliance with all applicable requirements of the Code and ERISA through the date on which the Company assumes the duties of plan sponsor and administrator thereof. Such assumption shall occur as of April 1, 1998 or such other date as may be agreed upon by Marathon and Ashland.

Section 10.13 Non-Qualified and Deferred Compensation Plans. The Company shall establish and maintain non-qualified and deferred compensation plans as follows.

(a) Excess Plans. The Company shall establish excess benefit plans designed to provide benefits in excess of the limits imposed by Code §§ 415 and 401(a)(17) for defined benefit plans. For Ashland Transferred Employees, such excess plan shall coordinate benefits with any equivalent excess benefit plan of Ashland for Ashland Transferred Employees in a manner comparable to the coordination of qualified defined benefit plan benefits, subject to the procedure outlined in Appendix C entitled “the Description of Benefit Calculations and Offsets for the Marathon Ashland Petroleum LLC Retirement Plan and Non-Qualified Benefit Plans.” For Marathon Transferred Employees, the Company-established excess benefit plans shall be exclusively responsible for payment of appropriate benefits. For Marathon or Ashland individuals who transfer to the Company after December 31, 1998, the Company-established excess plans shall coordinate benefits with any equivalent excess benefit plan of Ashland or Marathon in a manner comparable to the coordination of qualified defined benefit plan benefits, as described in paragraphs (iii) and (iv) of Section 10.5(c) hereof.

(b) Emro Marketing Company Excess Benefit Plan. The Emro Marketing Company Excess Benefit Plan, in existence at Emro Marketing Company immediately prior to the time Marathon’s interest in Emro Marketing Company or its successor is transferred to the Company, shall continue in existence and will be sponsored by Speedway SuperAmerica LLC.

(c) Emro Marketing Company Deferred Compensation Plan. The Emro Marketing Company Deferred Compensation Plan (a non qualified deferred compensation plan), in existence at Emro Marketing Company immediately prior to the time Marathon’s interest in Emro Marketing Company or its successor is transferred to the Company, shall continue in existence and will be sponsored by Speedway SuperAmerica LLC. Marathon shall reimburse the Company for the amount of any benefits paid under the Deferred Compensation Plan relating to a participant’s period of service prior to the time Marathon’s interest in Emro Marketing Company

106

or its successor was transferred to the Company. Such reimbursement shall occur at the time a benefit is paid from this Deferred Compensation Plan and shall include the amount attributable to the benefit accumulated for each participant at the date of such transfer and the applicable amount of interest, income or other earnings associated with and credited to such benefit from the date of such transfer to the date of such reimbursement. Marathon shall be entitled to the tax deduction related to any such reimbursement.

Xxxxxxx 00.00 Xxxxxxx XXXX.

(a) Division. Ashland agrees to make good faith reasonable efforts to cooperate with the Company in securing the consent of the Oil, Chemical & Atomic Workers International Union Locals 3-214 and 0-000 (xxxxxxxx to as “Catlettsburg”), 0-000 (xxxxxxxx to as “Canton”) and 0-000 (xxxxxxxx to as “Freedom”) to divide the assets attributable to Ashland and the employees and retirees in these locals that are in the Ashland Inc. Welfare Benefit Plans Trust (the “Ashland VEBA”) among these three locals. This division shall be based upon the employee contributions history for group term life insurance coverage that Ashland has regarding these three locals from January 1, 1982 through December 31, 1997. Based upon this employee contributions history, the amount in the Ashland VEBA shall be apportioned, effective as of the Closing Date, among members of the Catlettsburg, Canton, and Freedom bargaining units in the proportion that their respective employee contributions histories bear to the total employee contributions. Once the amounts are so apportioned among the three locals, the amount allocated to Canton shall be further divided. This division shall be between the active Canton employees who become employees of the Company after their period of loan is completed and the retirees related to Canton at that time. The amount of the Ashland VEBA allocated to Canton, as a whole, shall be further divided between the said active employee group and the said retiree group in the proportion that the total amount of each such group’s in force group term life insurance bears to the total amount attributable to Canton. Such division shall be effective as of the Closing Date and the respective portions shall be separately accounted for from that date forward. Benefits payment and contributions made by employees with respect to each portion shall be charged to the respective portions.

(b) Transfer. The amounts allocated to Catlettsburg and Canton active employees referred to in Section 10.14(a) shall be transferred to separate trust(s) sponsored by the Company which are determined by the Internal Revenue Service to be qualified under Sections 501(a)(9) and 505 of the Code. The Company shall be responsible for obtaining the required ruling from the Internal Revenue Service on the tax exempt status of such trust(s). Until such qualification has been obtained, Ashland shall continue to administer and separately account for all VEBA assets and liabilities. Ashland shall retain in its Ashland VEBA the assets allocated to the Canton retirees and Freedom.

(c) Alternative. If the three locals identified in this Section 10.14 fail to agree to divide the Ashland VEBA in the manner contemplated by Section 10.14(a), Marathon, Ashland and the Company agree to cooperate and use their reasonable best efforts, in good faith, to arrive at an alternative equitable division of the Ashland VEBA to which the relevant parties and the three locals will mutually agree.

107

Section 10.15 Welfare Plans.

(a) General. Consistent with the terms of this Agreement, the Company shall institute such welfare plans and such other employment policies and practices as it may, from time to time, determine.

Ashland and Marathon shall also each be responsible for issuing any required Certificates of Creditable Coverage under the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) to its transferred or terminated employees. All transferred employees will be immediately eligible to participate in the Company’s health or medical plans, provided they were eligible for coverage under an Ashland, SuperAmerica, Marathon or Emro plan immediately prior to transfer.

(i) Marathon shall, with the exception of members of the Teamsters at the Detroit Refinery, Detroit Terminal and Louisville Terminal, and all Emro employees, retain all medical insurance, life insurance and other liabilities for employees who are retired or inactive as of the Effective Date of the Company.

(X) retiree medical, dental and life coverage for individuals who retired as members of OCAW Locals 3-214 and 3-305 (Catlettsburg), and

(C) as may otherwise be agreed to with these locals in respect of disabled or inactive employees who are members of the union and eligible for Part I Long Term Disability benefits whether or not they

108

have satisfied the initial waiting period as of the date they would have otherwise been transferred ( specifically excluding any Ashland LTD Part II recipients),

retain all medical, dental, life insurance and other liabilities for employees who are retired or inactive as of the Employment Transfer Date. Ashland shall also retain responsibility for all medical, dental and life insurance and other liabilities for employees who are not transferred to the Company.

(iv) The Company will assume Ashland’s medical, dental and life insurance and other obligations for individuals who are members of Teamsters Local 975 at Bloomington and Teamsters Local 120 at St. Xxxx Park, and OCAW Locals 3-214 in Catlettsburg and Kenova and 3-505 in Catlettsburg or who are retired as members of those locals and, if required by agreements with those locals, disabled or inactive employees who are members of those locals. Marathon, Ashland and the Company will make good faith reasonable efforts to secure the agreement of the unions, but in the event no agreement can be reached a mutually agreed upon method for assessing costs of disabled or inactive employees to Ashland will be established. Additionally, the Company shall assume Ashland’s medical, dental and life insurance and other obligations under the multiemployer Teamster plan for Teamster members at Teamster Locals 114 at Cincinnati, 236 at Kuttawa and 135 at Richmond. Finally, the Company shall also assume Ashland’s medical, dental and life insurance and other obligations with regard to active employees who are transferred to the Company and who are members of the Refinery Workers Union Local 84 at Louisville and who are members of OCAW Local 7-450 at Canton.

(v) Except as required pursuant to a collective bargaining agreement as described in clause (iv) above, the Company shall not assume responsibility for any long- term disability benefit due to any injury incurred prior to the date of an employee’s transfer to the Company.

(vi) Marathon, Ashland and the Company each agrees to maintain workers’ compensation coverage for the Loaned Employees as required by the jurisdiction in which the individual will be performing services.

(vii) Obligations of Marathon and Ashland that are not expressly assumed by the Company in this Agreement shall remain with Marathon and Ashland, as the case may be.
