NOW, THEREFORE, the parties hereto agree as follows:

ARTICLE I

Transactions and Closing

Upon the terms and subject to the conditions set forth herein, at the Closing (as defined in Section 1.05), the parties shall consummate the MAP Partial Redemption and each of the other Transactions set forth in Sections 1.02, 1.03 and 1.04 as follows.  Subject to Section 9.10, the parties hereto intend that none of the Transactions that this Article I contemplates will be effected on the Closing

3

Date (as defined in Section 1.05) shall be effective unless all of such Transactions are effected on the Closing Date.

SECTION 1.01.MAP Partial Redemption.  As part of the Transactions, but prior to consummating the other Transactions set forth in Sections 1.02, 1.03 and 1.04, MAP shall redeem a portion of the 38% Membership Interest (as defined in Section 14.02) owned by Ashland for a redemption price payable as follows:  (i) accounts receivable of MAP, each with a Federal income Tax basis no less than its face amount, selected in accordance with the protocol set forth in Exhibit A, with a total Value (as defined in Section 14.02) equal to the product of (x) the Estimated MAP Partial Redemption Amount (as defined in Section 14.02) and (y) the AR Fraction (as defined in Section 14.02) (such product, the “AR Amount”) (the “Distributed Receivables”) and (ii) cash in an amount equal to the Estimated MAP Partial Redemption Amount minus the AR Amount (such difference, the “Cash Amount”), by wire transfer of immediately available funds to an Ashland bank account which shall be designated in writing by Ashland at least two business days prior to the Closing Date (the “MAP Partial Redemption”).  MAP shall increase the MAP Partial Redemption Amount (as defined in Section 14.02) payable in the MAP Partial Redemption as directed by Marathon if Marathon determines, in its sole judgment after giving due consideration to the requirements of any potentially applicable fraudulent transfer or conveyance Law, that the aggregate amount of the MAP Partial Redemption Amount (before giving effect to such increase) and the Capital Contribution (as defined in Section 1.03(b)) is not reasonably equivalent to the aggregate value immediately prior to the consummation of the Transactions, as determined by Marathon in its sole discretion, of (i) Ashland’s Membership Interest, (ii) the Maleic Business and (iii) the VIOC Centers.  In the event that Marathon makes the determination contemplated by the immediately preceding sentence, any resulting increase in the MAP Partial Redemption Amount shall be payable in any combination of cash and accounts receivable of MAP as determined by Marathon.  If at any time Marathon determines that it is reasonably likely to direct MAP to increase the MAP Partial Redemption Amount pursuant to the second sentence of this Section 1.01, Marathon shall provide prompt notice of such determination to Ashland, including a good faith estimate of any such increase.

SECTION 1.03.HoldCo Borrowing; Capital Contribution; Conversion Merger.  Promptly following the consummation of the Maleic/VIOC Contribution, the MAP/LOOP/LOCAP Contribution and the Reorganization Merger pursuant to Section 1.02, the parties shall consummate each of the following Transactions:

(i)subject to Section 5.01(e), each issued and outstanding share of HoldCo Common Stock shall be converted into the right to receive (x) one duly issued, fully paid and nonassessable

15

share of New Ashland Inc. Common Stock and (y) a number of duly issued, fully paid and nonassessable shares of Marathon Common Stock equal to the Exchange Ratio (as defined in Section 4.03(b));

(ii)all of the limited liability company interests in Merger Sub issued and outstanding immediately prior to the Acquisition Merger Effective Time shall remain outstanding without change; and

(iii)each share of New Ashland Inc. Common Stock held by HoldCo immediately prior to the Acquisition Merger Effective Time shall automatically be canceled and retired and shall cease to exist, and no consideration shall be delivered or deliverable in exchange therefor.

(d)If, after the first trading day of the Averaging Period and prior to the Acquisition Merger Effective Time, the outstanding shares of Marathon Common Stock shall have been increased, decreased, changed into or exchanged for a different number of shares of Marathon Common Stock in any case as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, combination or exchange of shares or other similar change in capitalization, then an appropriate and proportionate adjustment shall be made to the Exchange Ratio.

SECTION 4.04.Limited Liability Company Agreement.  The limited liability company agreement of Merger Sub as in effect immediately prior to the Acquisition Merger Effective Time shall be the limited liability company agreement of the business entity surviving the Acquisition Merger, Merger Sub, until thereafter changed or amended as provided therein or by applicable Law.

(e)No Fractional Shares.  (i)No certificates or scrip representing fractional shares of Marathon Common Stock shall be issued upon the conversion of HoldCo Common Stock pursuant to Section 4.03, and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a holder of Marathon Common Stock.  For

22

purposes of this Section 5.01(e), all fractional shares to which a single record holder would be entitled shall be aggregated and calculations shall be rounded to three decimal places.  Notwithstanding any other provision of this Agreement, each holder of Certificates who otherwise would be entitled to receive a fraction of a share of Marathon Common Stock (determined after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount equal to the product of such fractional part of a share of Marathon Common Stock multiplied by the Fair Market Value.

Common Stock or Marathon Common Stock, as applicable, as contemplated by Section 5.01(c).

(g)Lost Certificates.  If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by New Ashland Inc., the execution of an indemnity

23

reasonably satisfactory to New Ashland Inc. (and, if required by New Ashland Inc., the posting by such person of a bond in such reasonable amount as New Ashland Inc. may direct, as indemnity) against any claim that may be made against it with respect to such Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the applicable Acquisition Merger Consideration with respect to the shares of HoldCo Common Stock formerly represented thereby, and any dividends or other distributions such holder has the right to receive in respect thereof, pursuant to this Agreement.

(h)Withholding Rights.  Each of New Ashland Inc. and Marathon shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Certificates and any holder of Dissenters’ Shares such amounts as may be required to be deducted and withheld by New Ashland Inc. or Marathon, as applicable, with respect to the making of such payment under the Code or under any provision of state, local or foreign Tax Law.  To the extent that amounts are so withheld and paid over to the appropriate Tax Authority (as defined in Section 14.02), New Ashland Inc. or Marathon, as applicable, will be treated as though it withheld an appropriate amount of the type of consideration otherwise payable pursuant to this Agreement to any holder of Certificates or Dissenters’ Shares, sold such consideration for an amount of cash equal to the fair market value of such consideration at the time of such deemed sale and paid such cash proceeds to the appropriate Tax Authority.  Such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares represented by the Certificates or Dissenters’ Shares, as the case may be, in respect of which such deduction and withholding was made.

(i)No Liability.  None of the Ashland Parties, the Marathon Parties or the Exchange Agent shall be liable to any person in respect of any shares of New Ashland Inc. Common Stock (or dividends or distributions with respect thereto), Marathon Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law.  If any Certificate has not been surrendered prior to five years after the Acquisition Merger Effective Time (or immediately prior to such earlier date on which Acquisition

SECTION 6.01.Organization, Standing and Power.  Ashland is duly organized, validly existing and in good standing under the Laws of the Commonwealth of Kentucky and has full corporate power and authority to own, lease and otherwise hold its properties and to conduct its businesses as presently conducted.  Each Significant Ashland Subsidiary (as defined in this Section 6.01) is duly organized, validly existing and, to the extent such concept or a similar concept exists in the relevant jurisdiction,

26

assumed by HoldCo pursuant to the Transaction Agreements or the Ancillary Agreements, and except as otherwise expressly contemplated by the Transaction Agreements or the Ancillary Agreements, immediately prior to the Acquisition Merger, HoldCo will not have any indebtedness for borrowed money or any other liabilities (whether accrued, absolute, liquidated, unliquidated, fixed, contingent, disputed, undisputed, legal or equitable).

(d)As of the Closing Date, Ashland, before consummation of the Transactions, and New Ashland Inc., after giving effect to the Transactions, will not be insolvent, as insolvency is defined under any of the Uniform Fraudulent Transfer Act, as approved by the National Conference of Commissioners on Uniform State Laws in 1984, as amended (the “UFTA”), the Uniform Fraudulent Conveyance Act, as approved by the National Conference of Commissioners on Uniform State Laws in 1918, as amended (the “UFCA”), and the U.S. Bankruptcy Code, Title 11 of the U.S.C., as amended (the “Bankruptcy Code”).  Without limiting the generality of the foregoing, as of the Closing Date, with respect to each of Ashland, before consummation of the Transactions, and New Ashland Inc., after giving effect to the Transactions:  (i) the sum of such entity’s debts will not be greater than all of such entity’s assets at a fair valuation (as such terms are defined in the UFTA), and the sum of such entity’s debts will not be greater than all of such entity’s property, at a fair valuation (as such terms are defined in the Bankruptcy Code); (ii) the present fair saleable value of such entity’s assets will not be less than the amount that will be required to pay such entity’s probable liability on its existing debts as they become absolute and matured (as such terms are defined in the UFCA); (iii) such entity will not intend to incur, or believe or reasonably should believe that it would incur, debts beyond its ability to pay as they become due (as such terms are defined in the UFTA), such entity will not intend or believe that it will incur debts beyond its ability to pay as they mature (as such terms are defined in the UFCA), and such entity will not intend to incur, or believe that it would incur, debts that would be beyond its ability to pay as such debts mature (as such terms are defined in the Bankruptcy Code); and (iv) such entity will not be engaged and will not be about to engage in a business or transaction for which the remaining assets of such entity are unreasonably small in relation to such business or transaction (as such terms are defined in

37

the UFTA), such entity will not be engaged and will not be about to engage in a business or transaction for which the property remaining in such entity’s hands is an unreasonably small capital (as such terms are defined in the UFCA), and such entity will not be engaged in business or a transaction, and will not be about to engage in business or a transaction, for which any property remaining with such entity is an unreasonably small capital (as such terms are defined in the Bankruptcy Code).

38

SECTION 9.03.Reasonable Best Efforts; Notification.  (a)Upon the terms and subject to the conditions set forth in this Agreement, each of the parties shall use its reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Transactions, including (i) the obtaining of all necessary actions or nonactions, waivers, consents, orders, authorizations and approvals from Governmental Entities and the making of all necessary registrations, declarations and filings (including filings with Governmental Entities, if any) and the taking of all reasonable steps as may be necessary to obtain an approval or waiver from, or to avoid an action or proceeding by, any Governmental Entity, (ii) the obtaining of all necessary consents, approvals or waivers from third parties, (iii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or any other Transaction Agreement or the consummation of the Transactions, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed and (iv) the execution and delivery of any additional instruments necessary to consummate the Transactions and to fully carry out the purposes of the Transaction Agreements.  In connection with and without limiting the foregoing, the Ashland Parties and the Marathon Parties shall (i) take all action necessary to ensure that no state takeover statute or similar statute or regulation is or becomes applicable to any Transaction Agreement, any Ancillary Agreement or any Transaction and (ii) if any state takeover statute or similar statute or regulation becomes applicable to any Transaction Agreement, any Ancillary Agreement or any Transaction, take all action necessary to ensure that the Transactions may be consummated as promptly as practicable on the terms contemplated by the Transaction Agreements.  Notwithstanding the foregoing, Ashland and its Representatives shall not be prohibited under this Section 9.03(a) from taking any action permitted by Section 8.02.  Nothing in this Section 9.03(a) shall be deemed to require Marathon to waive any rights or agree to any limitation on the operations of Marathon or any of its subsidiaries or to dispose of any asset or collection of assets of any Marathon Party or any of their respective subsidiaries or affiliates, in each case that would have a

59

material adverse effect on the business, condition (financial or other) or results of operations of (i) MAP, the Maleic Business and the VIOC Centers, taken as a whole, or (ii) Marathon and its subsidiaries, taken as a whole.

(b)Upon the terms and subject to the conditions set forth in this Agreement, Ashland shall use its reasonable best efforts to cause the condition set forth in Section 10.02(c) (Specified Consents) to be satisfied.  The parties, together with their financial advisors, shall consult periodically regarding the scope of “reasonable best efforts,” which will not require Ashland to incur commercially unreasonable costs to satisfy such condition.  With respect to the Ashland Public Debt (as defined in this Section 9.03(b)), the parties acknowledge that Ashland may obtain consents through a tender offer or consent solicitation (or combination thereof), to be consummated on the Closing Date and to be commenced on a date mutually agreed by Ashland and Marathon but in any event no later than five business days after the satisfaction of the last to be satisfied of the conditions set forth in Sections 10.01(a) (Ashland Shareholder Approval), 10.01(c) (Antitrust) and 10.01(f) (Receipt of Private Letter Rulings; Tax Opinions) to expressly permit the Transactions and eliminate indenture covenants, certain events of default and other relevant provisions, all as reasonably deemed by Ashland necessary to consummate the Transactions (or, in the case of a combined tender offer and consent solicitation, otherwise desirable).  “Ashland Public Debt” means securities outstanding as of the last day of the month immediately preceding the month in which the tender offer and/or consent solicitation is commenced (the “Debt Consent Measurement Date”), issued under the Indenture dated as of August 15, 1989, between Ashland and Citibank, N.A. and the Amendment and Restatement thereof dated as of August 15, 1990 (the “Indentures”), other than any such securities issued after the date of this Agreement.  For purposes of this Section 9.03(b) and Section 10.02(c), receipt of consents from the holders of not less than 66-2/3% in principal amount of the Outstanding Securities (as defined in the Indentures) of any series constitutes a consent with respect to the entire principal amount as of the Debt Consent Measurement Date, of such series.  For the avoidance of doubt, receipt of consents from the holders of less than 66-2/3% in principal amount of the Outstanding Securities of any series shall not constitute a consent with respect to any portion of such series.

60

(c)The Marathon Parties shall use their reasonable best efforts (not including the payment of any consideration) to obtain, prior to the Closing, the written consent of Pilot Corporation, as contemplated by the Global Obligations Agreement among MAP, Speedway SuperAmerica LLC, USX Corporation, Pilot Corporation, Ashland, James A. Haslam II, James A. Haslam III, William E. Haslam and Pilot Travel Centers LLC, dated as of September 1, 2001, to the release of Ashland from its obligations contained in Article XIV of the Put/Call Agreement in accordance with Section 12.04 or, if such consent has not been obtained prior to the Closing, as promptly as possible thereafter.

(d)(i) The Ashland Parties and the Marathon Parties shall use their reasonable best efforts to cause AAA to deliver to Ashland and Marathon the Bring-Down AAA Opinions (as defined in Section 10.01(g)) and to cause HLHZ to deliver to Ashland and Marathon the Bring-Down HLHZ Opinion (as defined in Section 10.01(g)).  It is understood that (A) the Ashland Board may rely upon the Initial AAA Opinions and the Bring-Down AAA Opinions if the Ashland Board determines that such reliance is appropriate (subject to the indemnification and expense reimbursement arrangements previously agreed between Ashland and AAA) and (B) the Marathon Board may rely upon the Initial HLHZ Opinion and the Bring-Down HLHZ Opinion if the Marathon Board determines that such reliance is appropriate (subject to indemnification and expense reimbursement arrangements agreed between Marathon and HLHZ).

(ii)The Ashland Parties and the Marathon Parties acknowledge that the sole purpose of the Bring-Down Opinions is to update the Initial Opinions based on events occurring or facts being disclosed to AAA or HLHZ, as applicable, after the date of this Agreement and prior to the Closing.  Therefore, the parties intend that (A) each Bring-Down Opinion shall be based on the same valuation methodologies as the corresponding Initial Opinion, except for changes in methodology required as a result of events occurring or facts being disclosed to AAA or HLHZ, as applicable, after the date of this Agreement and prior to the Closing, and (B) events that are contemplated by AAA or HLHZ, as applicable, in the assumptions identified in its Initial Opinion should not be considered to

61

have occurred after the date of this Agreement in determining whether to deliver the corresponding Bring-Down Opinion.

(iii)Prior to the Closing, the Ashland Parties and MAP shall meet periodically with personnel of AAA and HLHZ and shall provide AAA and HLHZ access at all reasonable times upon reasonable prior request to their respective personnel, properties, books and records to the extent reasonably required for the purpose of delivering the Bring-Down Opinions.

(iv)At any time prior to the Closing, either Ashland or Marathon may request that AAA or HLHZ (A) update its Working Papers and analysis based on events occurring or facts disclosed to it after the date of this Agreement and prior to the date of such request and (B) based on such update, advise Ashland and Marathon of any facts or circumstances that are expected to result in it being unable to deliver its Bring-Down Opinion as of such date.  The Ashland Parties and the Marathon Parties shall be deemed to have jointly requested AAA or HLHZ to comply with any such request as promptly as practicable.

(v)In the event that AAA or HLHZ shall notify Ashland and Marathon of any facts or circumstances that are expected to result in it being unable to deliver its Bring-Down Opinion, Ashland or MAP, as applicable, shall have the right for a period of three months, or such shorter period as Ashland or MAP, as applicable, may elect, to meet and confer with, and provide additional information to, AAA or HLHZ, as applicable, for purposes of resolving any concerns relating to such facts and circumstances.  The Ashland Parties and the Marathon Parties shall use their reasonable best efforts to cause AAA or HLHZ, as applicable (based on such information and any efforts by Ashland or MAP, as applicable, to cure or otherwise address such facts and circumstances), to advise Ashland and Marathon as promptly as practicable after the expiration of such period

62

whether it would be able to deliver its Bring-Down Opinion as of such date.

(vi)The Working Papers of AAA and HLHZ relating to the Bring-Down Opinions, and any other Working Papers of AAA and HLHZ prepared pursuant to this Section 9.03(d) or otherwise relating to the Transactions, shall be made available to the Ashland Parties and the Marathon Parties upon request at any time prior to or after the Closing.  The Ashland Parties and the Marathon Parties shall use their reasonable best efforts to cause AAA and HLHZ to provide the Ashland Parties and the Marathon Parties reasonable access to the personnel of AAA and HLHZ involved in the Bring-Down Opinions, during normal business hours upon reasonable prior request, at any time prior to the Closing to discuss matters relating to such Working Papers.

(vii)At any time after August 1, 2004, or such earlier date as Ashland and Marathon may agree, and prior to the Closing, either Ashland or Marathon may request that AAA prepare a draft of the Bring-Down AAA Opinions or that HLHZ prepare a draft of the Bring-Down HLHZ Opinion, in each case marked to show any proposed changes from the applicable form included in Section 10.01(g) of the Marathon Disclosure Letter or in Section 10.01(g) of the Ashland Disclosure Letter, respectively, based on events occurring or facts disclosed to AAA or HLHZ after the date of this Agreement.  The Ashland Parties and the Marathon Parties shall be deemed to have jointly requested AAA or HLHZ to comply with any such request as promptly as practicable.  Ashland and Marathon may review and comment on any such proposed changes and may meet and confer with AAA and HLHZ for purposes of resolving any such comments prior to the Closing.

(e)Prior to the Closing, Ashland shall give prompt notice to Marathon of:  (i) any representation or warranty made by the Ashland Parties contained in the Transaction Agreements becoming untrue or incorrect, other than such failures to be true and correct that, in the aggregate, have not had and would not reasonably be expected to have an Ashland Material Adverse Effect;

63

provided that, for purposes of determining whether notice is required under this clause (i), the representations and warranties of the Ashland Parties shall be deemed not qualified by any references therein to (A) materiality generally or (B) whether or not any breach, circumstance or other item has resulted or would reasonably be expected to result in an Ashland Material Adverse Effect; (ii) the failure by any of the Ashland Parties to perform in all material respects their respective obligations under the Transaction Agreements; (iii) any notice or other communication any Ashland Party receives from any Governmental Entity or other person alleging, to the knowledge of Ashland, with reasonable specificity, that a Consent of, or registration, declaration or filing with, or permit from, such Governmental Entity or other person is or may be required in connection with the execution and delivery of or performance under any Transaction Agreement or the consummation of the Transactions, or that any such action would violate any applicable Law or breach or otherwise conflict with any material agreement to which any of the Ashland Parties are parties or are otherwise bound; or (iv) any action, suit, claim, investigation or proceeding commenced or, to its knowledge, threatened, in each case seeking to restrain or prohibit or otherwise materially affecting the Transactions; provided, however, that no such notification shall affect the representations, warranties or obligations of the Ashland Parties or the conditions to the obligations of the Ashland Parties or the Marathon Parties under the Transaction Agreements.

(f)Prior to the Closing, Marathon shall give prompt notice to Ashland of:  (i) any representation or warranty made by the Marathon Parties contained in the Transaction Agreements becoming untrue or incorrect, other than such failures to be true and correct that, in the aggregate, have not had and would not reasonably be expected to have a Marathon Material Adverse Effect; provided that, for purposes of determining whether notice is required under this clause (i), the representations and warranties of the Marathon Parties shall be deemed not qualified by any references therein to (A) materiality generally or (B) whether or not any breach, circumstance or other item has resulted or would reasonably be expected to result in a Marathon Material Adverse Effect; (ii) the failure by any of the Marathon Parties to perform in all material respects their respective obligations under the Transaction Agreements; (iii) any notice or other

64

communication any Marathon Party receives from any Governmental Entity or other person alleging, to the knowledge of Marathon, with reasonable specificity, that a Consent of, or registration, declaration or filing with, or permit from, such Governmental Entity or other person is or may be required in connection with the execution and delivery of or performance under any Transaction Agreement or the consummation of the Transactions, or that any such action would violate any applicable Law or breach or otherwise conflict with any material agreement to which any of the Marathon Parties are parties or are otherwise bound; or (iv) any action, suit, claim, investigation or proceeding commenced or, to its knowledge, threatened, in each case seeking to restrain or prohibit or otherwise materially affecting the Transactions; provided, however, that no such notification shall affect the representations, warranties or obligations of the Marathon Parties or the conditions to the obligations of the Ashland Parties or the Marathon Parties under the Transaction Agreements.  Marathon shall give prompt notice to Ashland of:  (i) any commitment referred to in the definition of Market MAC Event contained in Section 14.02 ceasing to be in full force and effect or (ii) any assertion by one or more Third Party Lenders who have provided such commitment with respect to the HoldCo Borrowing that a market disruption or other similar event has occurred that would result in the non-satisfaction of the Market MAC Condition to the HoldCo Borrowing.

(g)The Ashland Parties and the Marathon Parties shall comply with the obligations set forth in Sections 11.03(a) and 11.03(b) of the Put/Call Agreement with respect to the transfer of the Ashland LOOP/LOCAP Interest as if Marathon Company had exercised the Marathon Call Right (as defined in the Put/Call Agreement) thereunder on the date of this Agreement.  The Ashland Parties and the Marathon Parties shall use their reasonable best efforts (not including the payment of any consideration) to obtain (i) any consents or approvals (in addition to those contemplated by Sections 11.03(a) and 11.03(b) of the Put/Call Agreement) required for the transfer of the Ashland LOOP/LOCAP Interest to HoldCo and the acquisition of the Ashland LOOP/LOCAP Interest by Merger Sub in the Acquisition Merger as contemplated by this Agreement and (ii) express releases of Ashland, executed and delivered by all parties to the LOOP T&D Agreement or the LOCAP T&D Agreement, as applicable,

SECTION 9.10.Consequences of Inability To Transfer the Ashland LOOP/LOCAP Interest on the Closing Date.  The parties acknowledge that, pursuant to the MAP Governing Documents, Ashland is obligated to pay to MAP an amount equal to any dividends or distributions that Ashland receives in respect of the Ashland LOOP/LOCAP Interest net of certain Taxes imposed on Ashland or withheld from such dividends or distributions, and accordingly, the economic benefits of the foregoing have already been effectively transferred to MAP.  Accordingly, notwithstanding anything to the contrary contained herein, it shall not be a condition to the Closing or the effectiveness of any of the

71

Transactions that Ashland shall have contributed the Ashland LOOP/LOCAP Interest to HoldCo in accordance with Section 1.02(b) and the MAP/LOOP/LOCAP Contribution Agreements.  In the event that any consents or approvals required for the transfer of the Ashland LOOP/LOCAP Interest are not obtained prior to the Closing, and as a consequence Ashland is not able to contribute the Ashland LOOP/LOCAP Interest to HoldCo on the Closing Date, the provisions set forth in Sections 9.02(e), 13.03 and 13.04 of the Put/Call Agreement shall apply; provided, however, that, from and after the Closing, any payments described in the first sentence of this Section 9.10 shall be made by New Ashland Inc. to Merger Sub for the benefit of MAP.

SECTION 9.11.Consents Under Assigned Contracts.  Ashland and Marathon shall use their reasonable best efforts (not including the payment of any consideration) to obtain any Consents of third parties necessary to effect the assignment to and assumption by HoldCo of, and the release of Ashland from, the Assigned Contracts (as defined in each of the Maleic Agreement and the VIOC Agreement), including in the case of the Marathon Parties by providing such assurances regarding performance by Merger Sub (as successor to HoldCo) after the Closing as may be reasonably required to obtain such Consents.

SECTION 9.12.Administrative Proceedings.  After the Closing, if the Marathon Parties receive notice or become aware of any consent decree or order, notice of violation, administrative enforcement action or similar administrative action (each, an “Administrative Proceeding”) relating to MAP and naming Ashland as a responsible party, the Marathon Parties shall promptly notify Ashland of such Administrative Proceeding.  Ashland may take, and MAP shall provide Ashland with such cooperation as Ashland may reasonably request in connection with, any reasonable action to remove Ashland’s name from such Administrative Proceeding, so long as such removal is appropriate under the circumstances (taking into consideration the applicable provisions of the Transaction Agreements, the Ancillary Agreements, the MAP Governing Documents and applicable Law).  Nothing in this Section 9.12 is intended to affect MAP’s right to control its defense of such Administrative Proceedings.

SECTION 9.13.Replacement of Distributed Receivables.  To the extent any Distributed Receivable is reduced or canceled (other than as a result of a breach by

72

the obligor thereof of its payment obligation), or to the extent Ashland makes any payment in respect of proceeds of any Distributed Receivable to the holder of any Lien referred to in clause (iv) below after the collection of such Distributed Receivable in order to satisfy such Lien, including as a result of (i) defective or rejected goods or services, any cash discount or governmental or regulatory action, (ii) a setoff in respect of any claim by the obligor thereof, (iii) an obligation of MAP to pay the obligor thereof any rebate or refund or (iv) any Lien with respect to such Distributed Receivable, other than any Lien arising from actions or inactions of any of the Ashland Parties or their affiliates (and not any of the Marathon Parties or their affiliates), then MAP shall promptly assign to Ashland accounts receivable of MAP, selected in accordance with the protocol set forth in Exhibit A, with a total Value equal to, in the case of a reduction, the Value of such reduction, in the case of a payment, the amount of such payment, or, in the case of a cancelation, the Value of such Distributed Receivable.  Ashland shall assign back to MAP any Distributed Receivables that have been replaced pursuant to this Section 9.13.

SECTION 9.15.MAP Partial Redemption Amount. 

(a)Ashland shall use its reasonable best efforts to cause

73

Deloitte & Touche LLP (“D&T”) to provide Ashland and Marathon, on or prior to August 15, 2004, (i) a preliminary report prepared by D&T setting forth D&T’s good faith estimate as to the respective amounts of accounts receivable and cash to be distributed by MAP in the MAP Partial Redemption and (ii) any supporting schedules and other information prepared by D&T in connection with such report as Marathon may reasonably request.  Ashland shall use its reasonable best efforts to cause D&T to provide Ashland and Marathon any updates to such report, schedules and other information from time to time as Marathon may reasonably request.

(b)The Marathon Parties shall cause MAP to have available for distribution at Closing in the MAP Partial Redemption cash in an amount, and accounts receivable with a Value, which in the aggregate equal the Estimated MAP Partial Redemption Amount.  The Ashland Parties and the Marathon Parties shall use their reasonable best efforts to cause MAP to have available for distribution at Closing in the MAP Partial Redemption cash in an amount equal to the Cash Amount and accounts receivable with a total Value equal to the AR Amount.  Notwithstanding the provisions of Section 8.01(c) or any provision of the MAP LLC Agreement (as amended by the MAP LLC Agreement Amendment or otherwise amended hereafter), and without requiring a vote pursuant to Section 8.07(b) of the MAP LLC Agreement (as amended by the MAP LLC Agreement Amendment or otherwise amended hereafter), in the event Marathon reasonably expects that MAP will not have sufficient cash and accounts receivable available for distribution to Ashland to fund the payment of the Estimated MAP Partial Redemption Amount (after taking into account MAP’s reasonably anticipated working capital requirements) on the expected Closing Date, MAP shall be permitted to sell or otherwise dispose of assets, or enter into sale/leaseback arrangements, in each case in arm’s-length transactions with unaffiliated third parties, that are treated for Federal income Tax purposes as dispositions, not borrowings, in order to raise funds to satisfy such funding requirement.

(c)If the Closing occurs, all Tax Items (as defined in the Tax Matters Agreement) from any sale, disposition or sale/leaseback arrangement effected pursuant to Section 9.15(b) that is not effected in the ordinary course of MAP’s business and is not reflected in MAP’s “Business/Tactical Plan & Budget 2004-2006” dated

74

December 16, 2003 shall be allocated to Marathon Company.  The Marathon Parties shall (i) promptly notify Ashland of any written proposal made or received by any of the Marathon Parties relating to such a sale, disposition or sale/leaseback arrangement, and in any event shall notify Ashland of any such proposed sale, disposition or sale/leaseback arrangement not less than five days prior to entering into an agreement to effect any such sale, disposition or sale/leaseback arrangement; (ii) in connection with any such proposal, advise Ashland in writing of the assets to be transferred, the identity of the proposed transferee and the material terms and conditions of the proposed sale, disposition or sale/leaseback arrangement; (iii) keep Ashland reasonably informed on a timely basis of the status and details of such proposed sale, disposition or sale/leaseback arrangement, prior to and after entering into an agreement to effect any such sale, disposition or sale/leaseback arrangement, including any details that may affect the timing of the Transactions, and provide Ashland with copies of all material documents related to such proposed sale, disposition or sale/leaseback arrangement; and (iv) use its reasonable best efforts to effect the closing of any such sale, disposition or sale/leaseback arrangement substantially concurrently with the Closing.

(d)Ashland shall provide Marathon not less than 90 days notice if Ashland intends to waive the condition set forth in Section 10.02(f), in which case the Marathon Parties shall cause MAP to have available for distribution at Closing in the MAP Partial Redemption such additional cash as may be required to comply with the first sentence of Section 9.15(b).

SECTION 9.16.Ashland Debt Obligation Amount.  No later than August 1, 2004, Ashland shall provide to Marathon a schedule setting forth estimates, prepared in good faith by Ashland in light of any communications with the Internal Revenue Service (the “IRS”), written or otherwise, of the Ashland Debt Obligation Amounts based on assumed Closing Dates occurring on the last day of each month from August of 2004 through June of 2005.  Ashland shall update such schedule promptly following any communication with the IRS, written or otherwise, that would materially affect the Ashland Debt Obligation Amount for any assumed Closing Date.  Within five business days of

75

Ashland’s receipt of the Private Letter Rulings, Ashland shall provide to Marathon a schedule setting forth the Ashland Debt Obligation Amount for each such assumed Closing Date after the date of such schedule.  Ashland shall not, without the prior written consent of Marathon, effect any repurchase, repayment or defeasance prior to the Closing Date of any debt outstanding as of the date of this Agreement (and any refinancings of such debt by Ashland or any of its affiliates) that would reduce the Ashland Debt Obligation Amount (taking into consideration any refinancing of such debt by Ashland or any of its affiliates), except to the extent required by the terms of such debt (including, with respect to obligations other than (i) the Ashland Public Debt, (ii) any other debt issued after the date of this Agreement to refinance any portion of the Ashland Debt Obligation Amount and (iii) Ashland’s industrial revenue bonds, as a result of any notice of Ashland’s intent to repurchase, repay or defease such obligations on an expected Closing Date; provided, that such notice is delivered by Ashland after the satisfaction of the last to be satisfied of the conditions set forth in Sections 10.01(a) (Ashland Shareholder Approval), 10.01(c) (Antitrust) and 10.01(f) (Receipt of Private Letter Rulings; Tax Opinions)).

Termination, Amendment and Waiver

SECTION 11.01.Termination.  This Agreement may be terminated at any time prior to the Closing, whether before or after receipt of the Ashland Shareholder Approval:

(a)by mutual written consent of Ashland and Marathon;

(b)by either Ashland or Marathon:

(i)if the Transactions are not consummated during the period ending on June 30, 2005 (such date, as extended in accordance with this Section 11.01(b)(i), the “Outside Date”), unless the failure to consummate the Transactions is the result of a material breach of the Transaction Agreements by the party seeking to terminate this Agreement; provided, however, that the passage of such period shall be tolled for any period (not to exceed three months):

(A)during which any party shall be subject to a nonfinal order, decree, ruling or action of any court of competent jurisdiction or other Governmental Entity restraining, enjoining or otherwise prohibiting the consummation of the Transactions;

(B)referred to in Section 9.03(d)(v); and

(C)referred to in the final proviso to Section 11.01(e); and

(D)beginning on June 30, 2005 if, on such date, all conditions set forth in Article X have been satisfied (or, to the extent permitted by Law, waived by the parties entitled to the benefit thereof) other than the condition set forth in Section 10.02(f) (and other than those conditions that by their nature are to be

81

satisfied on the Closing Date) unless, at any time during the three month period from June 30, 2005 through September 30, 2005, Ashland determines, after consultation with Marathon, that the condition set forth in Section 10.02(f) is not reasonably expected to be satisfied during such three month period;

provided further however, that in no event will the Outside Date be extended beyond September 30, 2005;

(ii)if any Governmental Entity issues an order, decree, ruling or judgment or takes any other action permanently enjoining, restraining or otherwise prohibiting any of the Transactions and such order, decree, ruling, judgment or other action becomes final and nonappealable;

(iii)if, upon a vote at the Ashland Shareholder Meeting (or any adjournment or postponement thereof), the Ashland Shareholder Approval is not obtained; or

(iv)if the party seeking to terminate this Agreement reasonably determines that the condition set forth in Section 10.01(f) has become incapable of satisfaction based on either: (A) amendments or modifications to Federal income Tax Law effective after the date of this Agreement, (B) a private letter ruling received by Ashland and Marathon from the IRS or (C) an official, written communication from the IRS regarding the matters set forth in Exhibit D;

(c)by Marathon, if any one or more of the Ashland Parties breach or fail to perform their representations, warranties or covenants contained in the Transaction Agreements, which breach or breaches or failure or failures to perform (i) would, individually or in the aggregate, give rise to the failure of a condition set forth in Section 10.03(a) or 10.03(b) and (ii) cannot be cured or, if curable, is not or are not cured within 60 days after written notice from Marathon (provided that the Marathon Parties are not then in breach of their representations, warranties or covenants contained in the Transaction Agreements, which breaches would give rise to

82

the failure of a condition set forth in Section 10.02(a) or 10.02(b));

(d)by Marathon, prior to the Cutoff Date, if:

(i)the Ashland Board withdraws or modifies, in a manner adverse to Marathon, or proposes publicly to withdraw or modify, in a manner adverse to Marathon, its approval or recommendation of the Transaction Agreements or the Transactions, fails to recommend to Ashland’s shareholders that they give the Ashland Shareholder Approval or adopts, approves or recommends, or proposes publicly to adopt, approve or recommend, any Competing Ashland Proposal; or

(e)by Ashland, if any one or more of the Marathon Parties breach or fail to perform their representations, warranties or covenants contained in the Transaction Agreements which breach or breaches or failure or failures to perform (i) would, individually or in the aggregate, give rise to the failure of a condition set forth in Section 10.02(a) or 10.02(b) and (ii) cannot be cured or, if curable, is not or are not cured within 60 days after written notice from Ashland (provided that the Ashland Parties are not then in breach of their representations, warranties or covenants contained in the Transaction Agreements, which breaches would give rise to the failure of a condition set forth in Section 10.03(a) or 10.03(b)); provided, however, for purposes of this Section 11.01(e), the Marathon Parties shall be deemed not to have breached or failed to perform their covenant to cause the HoldCo Borrowing to be advanced to HoldCo in accordance with Section 1.03(a) for up to three months following the day on which the Closing Date would otherwise occur but for the failure of the Marathon Parties to cause the HoldCo Borrowing to be advanced to HoldCo if (A) such failure results from a Market MAC Event and (B) the

83

Marathon Parties use their reasonable best efforts to cause the HoldCo Borrowing to be advanced to HoldCo as soon as practicable thereafter, including, to the extent necessary, by providing guarantees or other credit support from the Marathon Parties (to the extent they have not otherwise agreed to do so), agreeing to modifications in the pricing, terms or structure of the HoldCo Borrowing (reasonably acceptable to Ashland) or arranging alternative Third Party Lenders; or

(f)by Ashland in accordance with Section 11.05(b); provided, however, that Ashland shall have complied with all provisions thereof, including the notice provisions therein.

SECTION 11.02.Effect of Termination.  In the event of termination of this Agreement by either Ashland or Marathon as provided in Section 11.01, this Agreement shall forthwith become void and have no effect, without any liability or obligation on the part of any party hereto, other than Section 6.09 (Brokers), Section 7.09 (Brokers), the last sentence of Section 9.02 (Access to Information; Confidentiality), Section 9.04 (Fees and Expenses), this Section 11.02 and Article XIV (General Provisions), which provisions shall survive such termination, and except to the extent that such termination results from the material breach by a party of its representations, warranties or covenants set forth in the Transaction Agreements.  Without limiting the generality of the foregoing, in the event of termination of this Agreement by either Ashland or Marathon as provided in Section 11.01, none of the MAP Governing Documents shall be terminated, amended or modified as specified in the Transaction Agreements.

SECTION 11.03.Amendment.  This Agreement may be amended by the parties at any time before or after receipt of the Ashland Shareholder Approval; provided, however, that after receipt of the Ashland Shareholder Approval, there shall be made no amendment that by Law requires further approval by the shareholders of Ashland without the further approval of such shareholders.  This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto.

SECTION 11.04.Extension; Waiver.  At any time prior to the Closing, Ashland or Marathon may, to the extent permitted by Law, (a) extend the time for the performance of any of the obligations or other acts of the

84

Marathon Parties (in the case of an extension granted by Ashland) or the Ashland Parties (in the case of an extension granted by Marathon), (b) waive any inaccuracies in the representations and warranties contained in the Transaction Agreements or in any document delivered pursuant to the Transaction Agreements, (c) waive compliance with any of the agreements of the Marathon Parties (in the case of a waiver granted by Ashland) or the Ashland Parties (in the case of a waiver granted by Marathon) or (d) waive any condition to the obligations of the Ashland Parties (in the case of a waiver granted by Ashland) or the Marathon Parties (in the case of a waiver granted by Marathon); provided, however, that after receipt of the Ashland Shareholder Approval, there shall be made no extension or waiver that by Law requires further approval by the shareholders of Ashland without the further approval of such shareholders.  Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party.

SECTION 11.05.Procedure for Termination, Amendment, Extension or Waiver.  (a)  A termination of this Agreement pursuant to Section 11.01, an amendment pursuant to Section 11.03 or an extension or waiver pursuant to Section 11.04 shall, in order to be effective, require action by the Ashland Board or the Marathon Board, as applicable, or the duly authorized designee of the Ashland Board or the Marathon Board, as applicable.

(b)Ashland may terminate this Agreement pursuant to Section 11.01(f) only if, prior to the Cutoff Date, (i) the Ashland Board (or, if applicable, a majority of the disinterested members thereof) has received a Superior Proposal, (ii) in light of such Superior Proposal the Ashland Board shall have determined in good faith, after consultation with inside and outside counsel, that the failure to take such action would be reasonably likely to result in a breach of its fiduciary obligations under applicable Law, (iii) Ashland has notified Marathon in writing of the determination described in clause (ii) above, (iv) at least five business days have elapsed following receipt by Marathon of the notice referred to in clause (iii) above, (v) Ashland is in compliance in all material respects with Section 8.02 (No Solicitation) and (vi) Marathon is not at such time entitled to terminate this Agreement pursuant to Section 11.01(c).  Written

85

confirmation by an executive officer of Marathon that expressly states that Marathon accepts the fees due and paid by Ashland under Section 9.04 shall constitute acceptance by Marathon of the validity of any termination of this Agreement under Section 11.01(f) and this Section 11.05(b); provided that, if such written confirmation is not provided within five business days after Marathon’s receipt of payment of such fees, Marathon shall promptly refund such payment to Ashland without setoff.  It is understood and agreed that a valid termination of this Agreement in compliance with the provisions of this Section 11.05(b) shall not constitute a breach of any provision of this Agreement.

ARTICLE XII

Amendment of Existing MAP Agreements

SECTION 12.01.Asset Transfer and Contribution Agreement.  (a)  Environmental Indemnity.  After the Closing, subject to and in accordance with all terms, conditions, restrictions and limitations contained in Section 9.8 of the Asset Transfer and Contribution Agreement among Marathon Company, Ashland and MAP dated as of December 12, 1997, as amended (the “ATCA”), MAP shall direct and control all Remediation Activities (as defined in the ATCA) undertaken in connection with any Ashland Environmental Loss associated with the Ashland Transferred Assets (as such terms are defined in the ATCA).  The Ashland Parties and the Marathon Parties shall cooperate in transferring the direction and control of such Remediation Activities to MAP.  In addition, notwithstanding anything to the contrary contained in the ATCA, if the Closing occurs, New Ashland Inc. shall not have any liabilities or obligations:

(i)in excess of $50,000,000 in the aggregate for Ashland Environmental Losses under Section 9.2(c) of the ATCA incurred on or after January 1, 2004, except as otherwise provided in the last sentence of this Section 12.01(a);

(ii)arising out of the St. Paul Park QQQ Project to the extent incurred on or after January 1, 2003 other than the amounts to be paid pursuant to Section 9.09(b);

86

(iii)arising out of the Plains Settlement (as defined in Section 14.02) regardless of when incurred; or

(iv)under Section 9.8(f) of the ATCA.

From and after the Closing, MAP shall continue to treat and process any and all impacted groundwater associated with Remediation Activities undertaken in connection with any Ashland Environmental Loss (as defined in the ATCA) relating to the Catlettsburg, Canton and St. Paul Park refineries.  Notwithstanding anything to the contrary contained in this Section 12.01(a), such treatment and processing shall be at MAP’s sole cost and expense.  MAP shall have title to any and all hydrocarbons recovered during the treatment and processing of such impacted groundwater.  Ashland shall retain all Ashland Excluded Liabilities (as defined in the ATCA) as well as all liabilities and obligations associated with the Scharbauer and Holt Ranch S-P project and the S-P projects described on Schedule 9.2(c) to the Ashland Asset Transfer and Contribution Agreement Disclosure Letter (as defined in the ATCA).

(b)Other Indemnification.  After the Closing, the Ashland Parties shall not have any liabilities or obligations for breaches of representations or warranties under Section 9.2(a) of the ATCA, including the Claims (as defined in the ATCA) identified in Section 12.01(b) of the Ashland Disclosure Letter, regardless of whether any Claim thereunder has been asserted on or prior to the Closing Date.

(c)Department of Defense Claim.  Notwithstanding anything to the contrary contained in the ATCA or the other MAP Governing Documents, (i) MAP shall pursue the claims that MAP has asserted against the U.S. Department of Defense (the “DOD”) relating to alleged illegal price adjustments for jet fuel and other aviation fuel sold to the DOD by Ashland Petroleum Company from 1980 through 1990 (the “DOD Claims”) and (ii) New Ashland Inc. shall have the right to participate in the pursuit of the DOD Claims and to employ counsel, at its own expense, separate from the counsel employed by MAP, it being understood that MAP shall control, in consultation with New Ashland Inc., the pursuit of the DOD Claims.  MAP shall use its reasonable best efforts to prosecute the DOD Claims in accordance with this Section 12.01(c) until the DOD Claims

87

are finally determined pursuant to one or more final and nonappealable orders, decrees or judgments by a court of competent jurisdiction or by one or more settlement agreements approved by New Ashland Inc. (such approval not to be unreasonably withheld or delayed).  If MAP shall receive any recovery under the DOD Claims, whether by judgment, settlement or otherwise, Marathon or Merger Sub shall promptly pay to New Ashland Inc. an amount equal to (A) 38% of such recovery minus (B) 38% of MAP’s reasonable out-of-pocket costs and expenses in pursuing the DOD Claims.  If and to the extent MAP’s reasonable out-of-pocket costs and expenses incurred in the pursuit of the DOD Claims exceeds the ultimate recovery under the DOD Claims, New Ashland Inc. shall pay to Marathon an amount equal to 38% of such excess.

(d)Employee Benefit Matters.  (i)As of the Closing, except as expressly modified herein, the terms and conditions of Article X of the ATCA shall continue to apply with respect to all employees and former employees of MAP and its subsidiaries who were Ashland Transferred Employees (as defined in the ATCA) (the “Transferred MAP Employees”).

(ii)Without limiting the generality of Section 12.01(d)(i), from and after the Closing, MAP and its successors shall be solely responsible for all liabilities, obligations and commitments (including any costs and expenses) in connection with the provision of retiree medical and retiree life insurance benefits to the Transferred MAP Employees.  Such benefits shall be determined taking into account the combined service of each Transferred MAP Employee with Ashland and its subsidiaries and MAP and its subsidiaries.  For the avoidance of doubt, Ashland shall not have any liability, obligation or commitment in respect of retiree medical or retiree life insurance benefits for MAP employees, including Transferred MAP Employees, from and after the Closing.

(iii)Ashland shall remain solely responsible for any benefits under the Ashland & Affiliates Pension Plan (the “Ashland Pension Plan”) and for any benefits under the Ashland Leveraged Employee Stock Ownership Plan (the “Ashland LESOP”) accrued by each Transferred MAP Employee as of immediately prior to such employee’s Employment

88

Transfer Date (as defined in the ATCA).  Solely for purposes of qualifying for distributions and early retirement benefits pursuant to the Ashland Pension Plan and the Ashland LESOP, Ashland will continue to treat the Transferred MAP Employees as employed by an affiliated employer for so long as they remain actively employed by MAP or its successors or their affiliates.

(iv)In accordance with the terms of the Ashland Employee Savings Plan, as of the Closing, Ashland agrees to facilitate the ability of each Transferred MAP Employee who is currently employed by MAP and its subsidiaries immediately prior to the Closing to effect a “direct rollover” (within the meaning of Section 401(a)(31) of the Code) of his or her account balances under the Ashland Employee Savings Plan if such rollover is elected in accordance with applicable Law by such Transferred MAP Employee.  Marathon agrees to cause the Marathon Thrift Plan to accept a “direct rollover” to the Marathon Thrift Plan of such Transferred MAP Employees’ account balances (including promissory notes evidencing all outstanding loans) under the Ashland Employee Savings Plan.

(v)Except as provided in this Section 12.01(d), Ashland shall remain solely responsible for any individual contractual obligations with any Transferred MAP Employees (including any obligations to such employees pursuant to the Ashland Stock Plans, the Ashland Salary Continuation Plan and any other severance, change in control or incentive compensation plan or arrangement) to the extent that Ashland was liable for such obligations immediately prior to the Closing.

(vi)Subject to applicable Law, Ashland shall reasonably cooperate in providing MAP with complete data for any Transferred MAP Employees.

(vii)The parties agree that, in the event that MAP and its subsidiaries make any contributions to, or payments in respect of, any pension plans, post-retirement health and life

89

insurance plans or any other post-employment benefit arrangements, other than the Permitted Payments (as defined below), then MAP shall make a special non-pro rata distribution to Ashland in an amount equal to 38% of the amount by which any such contributions or payments exceed the Permitted Payments.  Any such distribution to Ashland pursuant to this Section 12.01(d)(vii) shall be effected through an increase in the MAP Partial Redemption Amount or through such other means as Ashland and MAP may mutually agree.  For purposes of this Section 12.01(d)(vii), “Permitted Payments” means:

(A) any benefit payments made in the ordinary course of business consistent with past practice to beneficiaries of such pension plans, post-retirement health and life insurance plans or post-employment benefit arrangements;

(B) contributions to the MAP Retirement Plan (the “MAP Qualified Pension Plan”) in an amount not in excess of the minimum amount necessary to avoid the required filing of information with the Pension Benefit Guaranty Corporation (“PBGC”) pursuant to Section 4010 of ERISA with respect to the 2003 information year, which filing would otherwise be due on April 15, 2004 (which amounts shall be contributed at the latest possible time to avoid such required filing);

(C) in the case of the MAP Qualified Pension Plan (1) if the pension funding relief (including relief related to the determination of the PBGC variable-rate premium (within the meaning of 29 C.F.R. 4006.3)) contemplated by H.R. 3108 (or any substantially similar legislation) (the “Pension Funding Relief”) is enacted into law on or prior to September 15, 2004, contributions in calendar year 2004 in an amount not in excess of the minimum amount necessary to avoid payment of the variable-rate premium for such plan for the 2004 plan year (taking into account any amounts

90

previously contributed to the MAP Qualified Pension Plan, including pursuant to the immediately preceding clause (B) and clause (C)(3) below), provided that such contributions shall not be made before the latest possible time that such contributions may be made and still be taken into account in determining whether any variable-rate premium is due for the 2004 plan year, using the method that produces the lowest variable-rate premium and reflects any exemptions and special rules under 29 C.F.R. 4006.5 and the highest discount rate permitted for the calculation of such variable-rate premium and such other actuarial assumptions as set forth in 29 C.F.R. 4006 or otherwise required under PBGC regulations and (2) if the Pension Funding Relief is enacted into law on or prior to September 15, 2005, contributions in calendar year 2005 in an amount not in excess of the minimum amount necessary to avoid payment of the variable-rate premium for such plan for the 2005 plan year (taking into account any amounts previously contributed to the MAP Qualified Pension Plan, including pursuant to the immediately preceding clauses (B) and (C)(1) and clause (C)(3) below), provided that such contributions shall not be made before the latest possible time that such contributions may be made and still be taken into account in determining whether any variable-rate premium is due for the 2005 plan year, using the method that produces the lowest variable-rate premium and reflects any exemptions and special rules under 29 C.F.R. 4006.5 and the highest discount rate permitted for the calculation of such variable-rate premium and such other actuarial assumptions as set forth in 29 C.F.R. 4006 or otherwise required under PBGC regulations and (3) until the Pension Funding Relief is enacted into law, contributions (made in amounts and at such times consistent with past practice) not in

91

excess of $120,000,000 in each of calendar year 2004 and 2005; and

(D) in the case of the MAP Qualified Pension Plan, contributions not in excess of the minimum additional amounts required (which amounts shall be contributed at the latest possible time) for such plan to satisfy the minimum funding requirements of Section 412 of the Code;

it being understood that any amounts previously contributed to the MAP Qualified Pension Plan (including under the immediately preceding clause (B), (C) (1)-(3) or (D)) shall be taken into account in determining any subsequent amounts permitted to be contributed under the immediately preceding clause (B), (C)(1)-(3) or (D) so as to avoid duplication of contributions.  Notwithstanding the foregoing, in no event may Permitted Payments under the immediately preceding clauses (B), (C)(1)-(3) and (D) in the aggregate exceed, for each of calendar years 2004 and 2005, an amount (the “Maximum Annual Permitted Payment”) equal to the greater of (x) the minimum contributions required to be paid in such year to satisfy the minimum funding requirements of Section 412 of the Code (based on the required due dates for such contributions) and (y) $120,000,000.  With respect to the 2005 calendar year, the Maximum Annual Permitted Payment shall be pro-rated by multiplying the Maximum Annual Permitted Payment by a fraction, the numerator of which is the number of months elapsed in such year through and including the Closing Date, and the denominator of which is 12.  At least 30 days in advance of any Permitted Payment described under clauses (B), (C)(1)-(3) or (D) of the definition thereof to be contributed by MAP or its subsidiaries to the MAP Qualified Pension Plan, MAP and/or its actuary shall provide Ashland with a good-faith estimate of such Permitted Payment, and with all information reasonably requested by Ashland (and any actuary designated by Ashland) to review and independently verify such Permitted Payment.

92

(e)Other Provisions.  After the Closing, the Ashland Parties and their affiliates shall not have any liabilities or obligations under Section 7.2(h) (Guarantees) or 7.2(l) (Marine Preservation Association) of the ATCA.  For the avoidance of doubt, the other liabilities and obligations of the Ashland Parties and their affiliates, and the liabilities and obligations of Marathon Company, MAP and MAP’s subsidiaries, under the ATCA, including those under Article IX thereof, shall continue in full force and effect after the Closing, except as provided in the Transaction Agreements.  After the Closing, Ashland shall not have any liabilities or obligations under the Parent Company Guarantee dated May 28, 2003 relating to a Crude Oil Sales Agreement with Saudi Arabian Oil Company effective June 1, 2003, as amended; provided, however, that nothing in the Transaction Agreements or the Ancillary Agreements shall prohibit Marathon from continuing to be a guarantor thereunder.

SECTION 12.02.Designated Subleases.  (a)  With respect to the Goldman Sachs Master Sublease Agreement dated as of January 1, 1998, between Ashland Oil, Inc. and Speedway SuperAmerica LLC and the Pitney Bowes Credit Corporation Master Subcharter Agreement, dated as of January 1, 1998, between Ashland and MAP (each, a “Designated Sublease”), Ashland shall use its reasonable best efforts to (i) purchase or otherwise acquire the property then leased under the Original Lease (as defined in the MAP LLC Agreement) and subleased to MAP pursuant to each Designated Sublease (the “Leased Property”) on or prior to the Closing and (ii) upon such purchase or other acquisition, contribute its interest in such Leased Property to MAP or one of its subsidiaries at no cost to MAP or such subsidiary on or prior to the Closing; provided, however, that (A) with respect to any such Original Lease, Ashland shall not be obligated to pay more than a reasonable amount as consideration to, or make more than a reasonable financial accommodation in favor of, or commence litigation against, any person (including in order to obtain any agreement, consent or cooperation of or from such person) in order to purchase or otherwise acquire the related Leased Property as contemplated by, and in accordance with, this Section 12.02(a) and (B) any additional cost associated with exercising an option under any such Original Lease to purchase the related Leased Property as described above shall be deemed not to

93

constitute an obligation to pay more than a reasonable amount.

(b)In the event that Ashland is unable to purchase or otherwise acquire the Leased Property related to a Designated Sublease in accordance with Section 12.02(a), then the Ashland Parties and the Marathon Parties shall use their reasonable best efforts (including entering into customary documentation reasonably acceptable in form and substance to the Ashland Parties and the Marathon Parties) to cause (i) all Ashland’s existing rights under such Original Lease and, as applicable, either the SuperAmerica Transaction Documents (as defined below) or Pitney Bowes Transaction Documents (as defined below), to be assigned to MAP, effective as of the Closing Date, (ii) MAP to assume, effective as of the Closing Date, all liabilities and obligations required to be performed or discharged after the Closing under such Original Lease (including the obligation to pay rent and any additional cost associated with exercising an option under such Original Lease to purchase the related Leased Property) and, as applicable, either the SuperAmerica Transaction Documents or Pitney Bowes Transaction Documents and (iii) the Ashland Parties and their affiliates to be released, effective as of the Closing Date, from all liabilities and obligations required to be performed or discharged after the Closing under such Original Lease and, as applicable, either the SuperAmerica Transaction Documents or Pitney Bowes Transaction Documents.  If the Ashland Parties and the Marathon Parties are able to effect the assignment, assumption and release in accordance with this Section 12.02(b) in connection with an Original Lease related to a Designated Sublease, on the Closing Date, New Ashland Inc. shall pay to MAP cash, by wire transfer of immediately available funds to a MAP bank account designated in writing by MAP at least two business days prior to the Closing Date, in an amount equal to the present value, discounted at a rate equal to the yield to average life of Marathon public debt having an average life similar to the remaining average life of such Original Lease, and based on such other assumptions as the parties shall reasonably agree upon, of the lowest cost alternative of (x) the payment of all rent required to be paid thereafter under such Original Lease (including for all renewal periods available under the terms of such Original Lease) or (y) the payment of all rent required to be paid thereafter under such Original Lease until the date of any

94

available option under such Original Lease to purchase the related Leased Property and the cost associated with exercising any such option.  Ashland shall reimburse Marathon for any reasonable out-of-pocket expenses incurred by Marathon relating to such assignment, assumption and release; provided, however, that, with respect to any Original Lease, Ashland shall not be obligated to pay more than a reasonable amount as consideration to, or make more than a reasonable financial accommodation in favor of, or commence litigation against, any person (including in order to obtain any agreement, consent or cooperation of or from such person) in order to effect the assignment, assumption, and release contemplated by, and in accordance with, this Section 12.02(b) with respect to such Original Lease and, as applicable, either the SuperAmerica Transaction Documents or Pitney Bowes Transaction Documents.  If the Ashland Parties and the Marathon Parties are able to effect the assignment, assumption and release in accordance with this Section 12.02(b) with respect to any Original Lease related to a Designated Sublease, such Designated Sublease shall thereupon terminate and none of the Ashland Parties or the Marathon Parties shall have any liabilities or obligations thereunder other than liabilities and obligations required to be performed or discharged before the Closing.

(c)In the event that, on or prior to the Closing, (x) Ashland is unable to purchase and contribute the Leased Property related to a Designated Sublease as contemplated by, and in accordance with, Section 12.02(a), and (y) the Ashland Parties and the Marathon Parties are unable to effect the assignment, assumption and release as contemplated by, and in accordance with, Section 12.02(b) with respect to such Original Lease and, as applicable, either the SuperAmerica Transaction Documents or Pitney Bowes Transaction Documents, then (i) MAP shall be entitled to continue to sublease the Leased Property pursuant to such Designated Sublease until the term of such Original Lease expires, (ii) Ashland shall use its reasonable best efforts to purchase or otherwise acquire the related Leased Property under such Original Lease and convey title to such Leased Property to MAP or one of its subsidiaries; provided, however, that (A) with respect to any such Original Lease, Ashland shall not be obligated to pay more than a reasonable amount as consideration therefor to, or make more than a reasonable financial accommodation in favor of, or commence litigation against, any person

95

(including in order to obtain any agreement, consent or cooperation of or from such person) in order to purchase or otherwise acquire the related Leased Property and (B) any additional cost associated with exercising an option under any Original Lease to purchase related Leased Property shall be deemed not to constitute an obligation to pay more than a reasonable amount and (iii) if Ashland subsequently acquires such Leased Property, Ashland shall convey title to such Leased Property to MAP or one of its subsidiaries at no cost (including transfer Tax expense) to MAP or such subsidiary at such time.

107

asserted in writing within three years after the Closing Date, failing which such claim shall be waived and extinguished;

(viii)under clauses (i), (ii), (iii), (iv) and (v) of Section 13.02(a) for any individual items where the Loss or alleged Loss relating

108

thereto is less than $100,000 and such items shall not be aggregated for purposes of clause (vii) of this Section 13.02(b);

(ix)under clauses (i), (ii), (iii), (iv) and (v) of Section 13.02(a) in the aggregate in excess of the amount equal to the sum of (A) the MAP Partial Redemption Amount, (B) the Capital Contribution and (C) $315,000,000; and

(x)under clauses (i), (ii), (iii) and (iv)(A) of Section 13.02(a) for breaches of representations, warranties or covenants referred to therein that are contained in this Agreement to the extent they result in indemnification payments hereunder in excess of $400,000,000 in the aggregate;

provided, however, that in determining the scope of Marathon’s indemnification obligations under this Section 13.02(a), any qualification as to materiality or references to Marathon Material Adverse Effect in any of the representations or warranties referred to in Section 13.02(a) shall be disregarded (it being understood that such qualifications as to materiality or Marathon Material Adverse Effect shall apply for purposes of determining whether there has been a breach in the first place).  Solely for purposes of this Article XIII, any Loss to the extent arising out of any event or occurrence on or prior to, or circumstance existing on or prior to, the Closing Date (and not to the extent arising out of any event, occurrence or circumstance existing after the Closing Date, other than the discovery of a pre-closing condition or the making or commencement of any claim, demand, suit, action, proceeding or investigation after the Closing Date to the extent relating to any event, occurrence or circumstance existing on or prior to the Closing Date) shall be considered in determining whether there shall have occurred (or there was reasonably expected to occur) a Marathon Material Adverse Effect as of the Closing Date.  The parties acknowledge that (x) the indemnification obligations referred to in clauses (vi) through (x) of Section 13.02(a) shall not be subject to any time limitations and (y) none of the indemnification obligations referred to in clauses (vi) through (x) of Section 13.02(a) shall be subject to any dollar limitations.  The preceding sentence is not intended to eliminate or amend any limitations on the indemnification

109

obligations of any Marathon Party under the ATCA or any other agreement that is not a Transaction Agreement or an Ancillary Agreement.

(c)Except as otherwise expressly contemplated or provided in the Transaction Agreements and the Ancillary Agreements, the Marathon Parties make no representations or warranties of any kind, either express or implied.  Except as otherwise contemplated or provided in the Tax Matters Agreement, any of the other Transaction Agreements or any of the Ancillary Agreements, the Ashland Parties acknowledge that their sole and exclusive remedy after the Closing with respect to any and all claims (other than (i) claims arising from covenants to the extent such covenants are to be performed after the Closing and (ii) claims of fraud) relating to the Transaction Agreements, the Ancillary Agreements and the Transactions shall be pursuant to the indemnification provisions set forth in this Article XIII.  In furtherance of the foregoing, except as otherwise contemplated or provided in the Tax Matters Agreement, any of the other Transaction Agreements or any of the Ancillary Agreements, the Ashland Parties hereby waive, from and after the Closing, any and all rights, claims and causes of action under any applicable Law (other than claims of, or causes of action arising from, (i) covenants to the extent such covenants are to be performed after the Closing and (ii) fraud) they may have against the Marathon Parties arising under or based upon the Transaction Agreements, the Ancillary Agreements and the Transactions (except pursuant to the indemnification provisions set forth in this Section 13.02).  The Ashland Parties shall take reasonable actions to mitigate Losses for which indemnification may be sought under this Section 13.02, as and to the extent a party is required to mitigate damages for breach of contract under the Laws of the State of New York.

SECTION 13.03.Calculation of Losses.  (a)  The amount of any Loss for which indemnification is provided in clause (i), (ii), (iii), (iv) or (v)(A) of Section 13.01(a) of this Agreement or clause (i), (ii), (iii), (iv) or (v)(A) of Section 13.02(a) of this Agreement shall be net of any amounts actually recovered by the indemnified party under the True Insurance Policies (as such term is defined in the ATCA) with respect to such Loss; provided, however, that the indemnified party shall not have any obligation to seek any such recovery under any

110

True Insurance Policy.  The amount of any Loss for which indemnification is provided pursuant to Section 13.01(a) or Section 13.02(a) of this Agreement 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 (as defined in the ATCA) 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 clauses (i) and (ii) in the second sentence of this Section 13.03, 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.

(b)No indemnified party shall be entitled to indemnification pursuant to Section 13.01(a) with respect to any Loss that has been taken account of in any adjustment pursuant to Section 1.05 of the Maleic Agreement.  If the amount of any Loss, at any time subsequent to the making of any payment for indemnification pursuant to Section 13.01(a) or 13.02(a), is reduced by recovery, settlement or otherwise under or pursuant to any claim, recovery, settlement or payment by or against any other person that is not an affiliate of the indemnified party, the amount of such reduction, less any costs,

111

expenses, premiums or other offsets incurred in connection therewith, shall promptly be repaid by the indemnified party to the indemnifying party.  Upon making any payment for indemnification pursuant to Section 13.01(a) or 13.02(a), the indemnifying party shall, to the extent of such payment, be subrogated to all rights of the indemnified party (other than any rights of such indemnified party under any insurance policies) against any third party that is not an affiliate of the indemnified party in respect of the indemnifiable Loss to which such payment relates.  Each such indemnified party shall duly execute upon request all instruments reasonably necessary to evidence and perfect the above described subrogation rights.

SECTION 13.04.Procedures.  (a)  Notice of Third Party Claims.  If any claim is asserted by any person not a party, or an affiliate or a Representative of a party, to this Agreement against an indemnified party under this Agreement (any such claim being a “Third Party Claim”) and such indemnified party intends to seek indemnification hereunder from a party to this Agreement, 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, accompanied by copies of all papers that have been served on the indemnified party 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 (if reasonably attainable) 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 only 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

112

indemnified party’s receipt thereof, copies of all written notices and documents (including court papers but excluding any materials that are subject to any applicable privilege or that constitute attorney work product) received by the indemnified party relating to the Third Party Claim.

(b)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, the defense of the Third Party Claim at its own expense using counsel of its choice reasonably acceptable to the indemnified party, by giving prompt written notice 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 in accordance with the first sentence of this Section 13.04(b) or diligently prosecute the defense of 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.  The indemnified party agrees to provide such reasonable cooperation to the indemnifying party and its counsel as the indemnifying party may reasonably request 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 who is not an affiliate or Representative of the indemnified party, 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

113

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 would not otherwise adversely affect the indemnified party.

(c)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 in accordance with the provisions of Section 13.04(b), 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 provide such reasonable cooperation to the indemnified party and its counsel as the indemnified party may reasonably request 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 who is not an affiliate or Representative of the indemnifying party, 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

114

settlement, compromise or consent includes an unconditional release of the indemnifying party from all liability and obligations arising out of such Third Party Claim.

(d)Other Claims.  In the event any indemnified party should have a claim against any indemnifying party under Section 13.01 or 13.02 that does not involve a Third Party Claim being asserted against or sought to be collected from such indemnified party, the indemnified party shall deliver notice of such claim with reasonable promptness to the indemnifying party.  Subject to Sections 13.01(b) and 13.02(b), the failure by any indemnified party so to notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to such indemnified party under Section 13.01 or 13.02, except to the extent that the indemnifying party demonstrates that it has been prejudiced by such failure.  The indemnifying party shall have 60 calendar days following its receipt of such notice to dispute its liability to the indemnified party under Section 13.01 or 13.02.  The indemnified party shall reasonably cooperate with and assist the indemnifying party in determining the validity of any claim for indemnity by the indemnified party and in otherwise resolving such matters.  Such cooperation and assistance shall include retention and (upon the indemnifying party’s request) the provision to the indemnifying party of records that are reasonably relevant to such matters, making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and providing such reasonable cooperation and assistance in the investigation and resolution of such matters as the indemnifying party may reasonably request.  If the indemnifying party does not notify the indemnified party within 60 days from its receipt of a notice pursuant to the first sentence of this Section 13.04(d) that the indemnifying party disputes the claim specified by the indemnified party in such notice, that claim shall be deemed a liability of the indemnifying party hereunder.  If the indemnifying party has timely disputed that claim, as provided above, that dispute may be resolved by proceedings in an appropriate court of competent jurisdiction in accordance with Section 14.10 if the parties do not reach a settlement of that dispute within 30 days after notice of that dispute is given.  Payment of the amount set forth in a notice of a claim pursuant to the first sentence of this Section 13.04(d) that has not been disputed shall be made

115

within 30 days after the expiration of the applicable 60 day notice period.  If the payment obligation has been disputed, payment shall be made 30 days after the expiration of the period for appeal of a final adjudication of the indemnifying party’s liability under this Agreement to the indemnified party with respect to such payment obligation.

(e)The foregoing provisions of this Article XIII shall not be applicable to any Tax Matters, it being understood that the indemnification obligations of New Ashland Inc. and Marathon with respect to all Tax Matters are set forth in the Tax Matters Agreement.

(f)The foregoing provisions of this Article XIII shall not be applicable to any Losses to the extent indemnification for such Losses is provided under the Franchise Agreements (as defined in the VIOC Agreement).

SECTION 14.03.Interpretation; Disclosure Letters.  When a reference is made in this Agreement to a Section or Article, such reference shall be to a Section or Article of this Agreement unless otherwise indicated.  The

123

table of contents and headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.  Whenever the words “include”, “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation”.  No item contained in any section of either the Ashland Disclosure Letter or the Marathon Disclosure Letter shall be deemed adequate to disclose an exception to a representation or warranty made in this Agreement, unless (i) such item is included (or expressly incorporated by reference) in a section of the applicable disclosure letter that is numbered to correspond to the section number assigned to such representation or warranty in this Agreement or (ii) it is readily apparent from a reading of such item that it discloses an exception to such representation or warranty.

SECTION 14.04.Severability.  If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule or Law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto.  Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible to the end that the transactions contemplated hereby are fulfilled to the greatest extent possible.

SECTION 14.05.Counterparts.  This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties.

SECTION 14.06.Entire Agreement; No Third-Party Beneficiaries.  The Transaction Agreements, taken together with the exhibits hereto and thereto, the Ashland Disclosure Letter and the Marathon Disclosure Letter, the Confidentiality Agreement, and the other agreements and instruments of the parties hereto delivered in connection herewith, (a) constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the

124

Transactions and (b) except for the provisions of Section 2.05, Article V, Section 12.06(b) and Article XIII (the “Third Party Provisions”), are not intended to confer upon any person other than the parties hereto any rights or remedies.  The Third Party Provisions may be enforced by the beneficiaries thereof; provided, however, that the shareholders of Ashland in their capacities as such shall not have any rights or remedies under this Agreement, and shall not be entitled to enforce the Third Party Provisions or make any Claims with respect thereto, unless and until the Closing shall have occurred.  For avoidance of doubt, (i) the shareholders of Marathon in their capacities as such shall not have any rights or remedies under this Agreement, (ii) after the Closing, holders of Dissenters’ Shares shall have the rights and remedies specified in Section 2.05 only and (iii) after the Closing, the holders entitled to receive HoldCo Common Stock in the Reorganization Merger shall have the rights and remedies specified in Article V only.  Notwithstanding the foregoing, the Confidentiality Agreement shall remain in effect in accordance with its terms and, except as expressly amended hereby, the MAP Governing Documents are ratified and affirmed and shall remain in full force and effect.

SECTION 14.07.Exercise of Rights and Remedies.  Except as this Agreement otherwise provides, no delay or omission in the exercise of, or failure to assert, any right, power or remedy accruing to any party hereto as a result of any breach or default hereunder by any other party hereto will impair any such right, power or remedy, nor will it be construed, deemed or interpreted as a waiver of or acquiescence in any such breach or default, or of any similar breach or default occurring later; nor will any waiver of any single breach or default be construed, deemed or interpreted as a waiver of any other breach or default hereunder occurring before or after that waiver.  The failure of any party to this Agreement to assert any of its rights under the Transaction Agreements or otherwise shall not constitute a waiver of such rights.

SECTION 14.08.Governing Law.  This Agreement shall be governed by, and construed in accordance with, the Laws of the State of New York, regardless of the Laws that might otherwise govern under applicable principles of conflicts of Laws thereof, except to the extent the Laws of Kentucky are mandatorily applicable to the Reorganization

125

Merger and the Conversion Merger and to the extent the Laws of Delaware are mandatorily applicable to the Acquisition Merger.

SECTION 14.09.Assignment.  Neither the Transaction Agreements nor any of the rights, interests or obligations under the Transaction Agreements shall be assigned, in whole or in part, by any of the parties without the prior written consent of the other parties, except that the rights, interests and obligations of any party under this Agreement or any of the other Transaction Agreements may be assigned by operation of law pursuant to a merger, consolidation or other business combination involving such party that would not reasonably expected to prevent or materially delay the consummation of the Transactions; provided, however, that any assignment pursuant to the exception set forth in this sentence shall not operate to release any party from its obligations under this Agreement or any of the other Transaction Agreements.  Subject to the preceding sentences, the Transaction Agreements will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

SECTION 14.10.Enforcement.  The parties agree that irreparable damage would occur in the event that any of the provisions of the Transaction Agreements were not performed in accordance with their specific terms or were otherwise breached.  It is accordingly agreed that, subject to Sections 13.01(c) and 13.02(c), the parties shall be entitled to an injunction or injunctions to prevent breaches of the Transaction Agreements and to enforce specifically the terms and provisions of the Transaction Agreements in any New York state court or any Federal court located in the Borough of Manhattan, The City of New York in the State of New York, this being in addition to any other remedy to which they are entitled at law or in equity.  In addition, each of the parties hereto (a) consents to submit itself to the personal jurisdiction of any New York state court or any Federal court located in the Borough of Manhattan, The City of New York in the State of New York in the event any dispute arises out of the Transaction Agreements or any Transaction, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (c) agrees that it will not bring any action relating to any Transaction Agreement or any Transaction in

126

any court other than any New York state court or any Federal court sitting in the Borough of Manhattan, The City of New York in the State of New York (provided, however, that this clause (c) shall not limit the ability of any party hereto to (i) file a proof of claim or bring any action in any court in which a bankruptcy or reorganization proceeding involving another party hereto is pending, (ii) file a counter-claim or cross-claim against another party hereto in any court in which a proceeding involving both such parties is pending or (iii) implead another party hereto in respect of a Third Party Claim in any court in which a proceeding relating to such Third Party Claim is then pending) and (d) waives any right to trial by jury with respect to any action related to or arising out of any Transaction Agreement or any Transaction.

2.The IRS issues a Ruling holding that the Capital Contribution described in Section 1.03(b) and the Conversion Merger described in Section 1.03(c), taken together with the Acquisition Merger described in Section 1.04(a) or the distribution by HoldCo of shares of New Ashland Inc. Common Stock described in Section 1.04(b), as the case may be, qualify as a reorganization under Section 368(a)(1)(D) of the Code.

3.The IRS issues a Ruling holding that the Acquisition Merger described in Section 1.04(a) or the distribution by HoldCo of shares of New Ashland Inc. Common Stock described in Section 1.04(b), as the case may be, qualifies as a distribution described in Section 355(a) of the Code and, accordingly, no gain or loss will be recognized by (and no amount will otherwise be included in the income of) the shareholders of HoldCo upon the receipt of such New Ashland Inc. Common Stock.

4.Either:

(a)The IRS issues a Ruling holding that the Acquisition Merger described in Section 1.04(a) will qualify as a reorganization under Section 368(a)(1)(A) of the Code; or

(b)If the IRS refuses to issue the Ruling described in paragraph 4(a) above, Cravath, Swaine & Moore LLP delivers a written opinion to Ashland, in form and substance reasonably satisfactory to the Ashland Board, concluding that the Acquisition Merger described in Section 1.04(a) will qualify as a reorganization under Section 368(a)(1)(A) of the Code; and Miller & Chevalier Chartered delivers a written opinion to Marathon, in form and substance reasonably satisfactory to the Marathon Board,

that such Acquisition Merger qualifies as a reorganization under Section 368(a)(1)(A) of the Code.

5.The IRS issues a Ruling holding that the shares of New Ashland Inc. Common Stock distributed to shareholders of HoldCo in the Acquisition Merger described in Section 1.04(a) or the distribution described in Section 1.04(b), as the case may be, will not be treated as “other property”, within the meaning of Section 356(a) of the Code, received in exchange for HoldCo stock in the Acquisition Merger.

Common Stock in the hands of HoldCo will be determined under Section 358(h)(1) of the Code, or will be excluded from such application solely by reason of Section 358(h)(2) of the Code; or

(b)(i) The IRS issues a Ruling holding that the effect of such assumption on such basis will be determined under Section 358(d)(1) of the Code; (ii) such Ruling sets forth with specificity a method of determining the amount of the resulting reduction to basis under Section 358(d)(1) of the Code; and (iii) based on such method, on representations as to the basis of the New Ashland Inc. Common Stock before such reduction, and on representations as to the value of the New Ashland Inc. Common Stock to be distributed by HoldCo as of the date of such distribution (and on any other date that might be relevant), Cravath, Swaine & Moore LLP delivers a written opinion to Ashland, in form and substance reasonably satisfactory to the Ashland Board, that the distribution of the New Ashland Inc. Common Stock by HoldCo will not result in the recognition of gain by HoldCo under Section 355(e) of the Code in an amount greater than would be so recognized if the effect on such basis had been determined under Section 358(h)(1) of the Code rather than Section 358(d)(1) of the Code; and Miller & Chevalier Chartered delivers a written opinion to Marathon, in form and substance reasonably satisfactory to the Marathon Board, concluding that the distribution of the New Ashland Inc. Common Stock by HoldCo does not result in the recognition of gain by HoldCo under Section 355(e) of the Code in an amount greater than would be so recognized if the effect on such basis had been determined under Section 358(h)(1) of the Code rather than Section 358(d)(1) of the Code.
