SECTION 4.05. Limitation on Ashland’s Ability To Exercise its Ashland Put Right. If prior to the Ashland Put Exercise Date, Marathon elects to Transfer all of its Membership Interests to a third party pursuant to Section 10.01(c) of the LLC Agreement, and in connection therewith delivers to Ashland the requisite Offer Notice pursuant to Section 10.04 of the LLC Agreement, Ashland shall not be permitted to exercise its Ashland Put Right for a period commencing on the date of Ashland’s receipt of such Offer Notice and ending on the earlier of (i) 120 days (270 days if a second request has been made under HSR) following such receipt, (ii) the closing of such Transfer, and (iii) the date such proposed Transfer by Marathon shall have been finally abandoned.

SECTION 6.01. Determination of Appraised Value of the Company. (a) Negotiation Period. If Marathon exercises its Special Termination Right or its Marathon Call Right or if Ashland exercises its Special Termination Right or its Ashland Put Right, then for a period of 60 days following the relevant Exercise Date, Marathon and Ashland shall negotiate in good faith to seek to reach agreement as to the Market Value of the Company. If Marathon and Ashland reach such an agreement, then the Market Value of the Company shall be deemed to be the amount so agreed upon by Marathon and Ashland.

(b) Appraisal Process. In the event Marathon and Ashland are unable to reach an agreement as to the Market Value of the Company within the 60-day period referred to in Section 6.01(a), then within five Business Days after the expiration of such 60-day period (such fifth Business Day being referred to herein as the “6.01 Appraisal Process Commencement Date”), Marathon and Ashland each shall select a nationally recognized investment banking firm to (i) prepare a report which (A) sets forth such investment banking firm’s determination of the Market Value of the Company (which shall be a single amount as opposed to a range) and (B) includes work papers which indicate the basis for and calculation of the Market Value of the Company (a “6.01 Appraisal Report”) and (ii) deliver to Marathon or Ashland, as the case may be, an oral and written opinion addressed to such party as to the Market Value of the Company. The fees and expenses of each investment banking firm shall be paid by the party selecting such investment banking firm. Each of Marathon and Ashland shall instruct its respective investment banking firm to (i) not consult with the other investment banking firm with respect to its view as to the Market Value of the Company prior to the time that both investment banking firms have delivered their respective opinions to Marathon or Ashland, as applicable, (ii) determine the Market Value of the Company in accordance with Section 6.01(c), (iii) deliver their respective 6.01 Appraisal Reports, together with their oral and written opinions as to the Market Value of the Company (the “6.01 Initial Opinion Values”), within 60 days after the 6.01 Appraisal Process Commencement Date, and (iv) deliver a copy of its written opinion and its 6.01 Appraisal Report to the Company, the other party and the other party’s investment banking firm at the time it delivers its oral and written opinion to Marathon or Ashland, as applicable.

If the 6.01 Initial Opinion Values differ and the lesser 6.01 Initial Opinion Value equals or exceeds 90% of the greater 6.01 Initial Opinion Value, the Market Value of the Company shall be deemed to be an amount equal to (i) the sum of the 6.01 Initial Opinion Values divided by (ii) two.

If the 6.01 Initial Opinion Values differ and the lesser 6.01 Initial Opinion Value is less than 90% of the greater 6.01 Initial Opinion Value, then:

(i) within two Business Days after both investment banking firms have delivered their respective opinions to Marathon or Ashland, as applicable, each investment banking firm shall, at a single meeting at which Marathon, Ashland, the Company and the other investment banking firm are present, make a presentation with respect to its 6.01 Initial Opinion Value. At such presentation, Marathon, Ashland, the Company and the other investment banking firm shall be entitled to ask questions as to the basis for and the calculation of such investment banking firm’s 6.01 Initial Opinion Value; and

(ii) Marathon and Ashland shall, within five Business Days after the date Marathon and Ashland receive the 6.01 Initial Opinion Values (such fifth Business Day being referred to herein as the “6.01 Subsequent Appraisal Process Commencement Date”), jointly select a third nationally recognized investment banking firm to (A) prepare a 6.01 Appraisal Report and (B) deliver an oral and written opinion addressed to Marathon and Ashland as to the Market Value of the Company. The fees and expenses of such third investment banking firm shall be paid 50% by Marathon and 50% by Ashland. Such third investment banking firm shall not be provided with the 6.01 Initial Opinion Values and shall not consult with the initial investment banking firms with respect thereto. During such five-Business Day period, Marathon and Ashland shall negotiate in good faith to independently reach an agreement as to the Market Value of the Company. If Marathon and Ashland reach such an agreement, then the Market Value of the Company shall be deemed to be the amount so agreed upon by Marathon and Ashland. If Marathon and Ashland are unable to reach such an agreement, then Marathon and Ashland shall instruct such third investment banking firm to (A) determine the Market Value of the Company in accordance with Section 6.01(c) and (B) deliver its 6.01 Appraisal Report, together with its oral and written opinion (the “6.01 Third Opinion Value”), within 60 days after the 6.01 Subsequent Appraisal Process Commencement Date. The Market Value of the Company in such circumstance shall

be deemed to be an amount equal to (A) the sum of (x) the 6.01 Third Opinion Value plus (y) whichever of the two 6.01 Initial Opinion Values is closer to the 6.01 Third Opinion Value (or, if the 6.01 Third Opinion Value is exactly halfway between the two 6.01 Initial Opinion Values, the 6.01 Third Opinion Value), divided by (B) two.

(c) Definition of Market Value of the Company. For purposes of this Agreement, the Market Value of the Company (the “Market Value of the Company”) means the fair market value of the combined common equity of the Company as of the relevant Exercise Date, (including, in the circumstance where Marathon has exercised its Marathon Call Right or its Special Termination Right or Ashland has exercised its Ashland Put Right, the Ashland LOOP/LOCAP Interest) assuming the consummation of a transaction designed to achieve the highest value of such combined common equity. In determining the Market Value of the Company, (i) consideration should be given as to (A) all possible transaction participants (other than Marathon or Ashland or their respective Affiliates) and categories of possible transactions; (B) a range of analytical methodologies, potentially including, but not limited to, the following: comparable trading analysis, comparable transaction analysis, discounted cash flow analysis, leveraged buyout analysis and break-up analysis; and (C) the value to the Company of all indemnification obligations of Marathon, USX and Ashland in favor of the Company pursuant to any Transaction Document (including, without limitation, Article IX of the Asset Transfer and Contribution Agreement), to the extent such indemnification obligations remain in effect after the Closing and (ii) no separate incremental value will be attributed to the Ashland LOOP/ LOCAP Interest. In determining the Market Value of the Company, no consideration should be given to the values that are initially assigned to assets of the Company for purchase accounting or tax accounting purposes. The Market Value of the Company as determined pursuant to this Section 6.01 is referred to herein as the “Appraised Value of the Company”, and the date on which the Market Value of the Company is so determined is referred to herein as the “Appraised Value Determination Date”.

SECTION 7.01. General. The fair market value of any Securities to be issued to Ashland on the Closing Date and on any subsequent Installment Payment Date, shall be determined pursuant to the following procedures (the fair market value of such Securities as so determined being the “Fair Market Value” of such Securities).

SECTION 7.02. Determination of Fair Market Value of Marathon Debt Securities. The Fair Market Value of any Marathon Debt Securities shall be deemed to be an amount equal to the aggregate stated principal amount of such Marathon Debt Securities.

SECTION 7.03. Determination of Fair Market Value of Actively Traded Marathon Equity Securities. (a) Fair Market Value Where There is No Holding Period. The Fair Market Value of any Actively Traded Marathon Equity Securities to be issued to Ashland on the Closing Date or applicable Installment Payment Date for which Marathon has not elected a Holding Period shall be deemed to be an amount equal to the product of (i) the aggregate number of such Actively Traded Marathon Equity Securities to be issued to Ashland multiplied by (ii) the Weighted Average Price (as defined below) of such Actively Traded Marathon Equity Securities on the National Market System of the NASDAQ or the relevant National Securities Exchange, as reported by The Wall Street Journal or, if not reported thereby, as reported by any other authoritative source, for the ten full Trading Days immediately preceding the Business Day immediately preceding the Closing Date or applicable Installment Payment Date; provided that at least five Trading Days prior to the commencement of such ten full Trading Day period (the “Required Disclosure Date”), Marathon shall have made appropriate public disclosure (including by issuing a press release and filing a copy of such press release with the Commission) of (A) the existence of the Transaction, (B) the Ashland Put Price and (C) the information required to be included in the Ashland Put Price Election Notice (each such public disclosure being a “Required Disclosure”). Marathon shall provide Ashland with a copy of each Required Disclosure prior to Marathon making such disclosure public. Any such Required Disclosure shall be in form and substance reasonably satisfactory to Ashland

and its counsel. For purposes of this Section 7.03(a), the “Weighted Average Price” means the quotient of (1) the product of (x) the number of shares in each trade in such Actively Traded Marathon Equity Securities that occurred during such ten full Trading Day period multiplied by (y) the price at which each such trade occurred, divided by (2) the total number of shares traded in such Actively Traded Marathon Equity Securities that occurred during such ten full Trading Day period. In the event of (i) any split, combination or reclassification of the class of Actively Traded Marathon Equity Securities to be issued to Ashland on the Closing Date or applicable Installment Payment Date, (ii) any issuance or the authorization of any issuance of any other securities in exchange or in substitution for the shares of such class of Actively Traded Marathon Equity Securities or (iii) any issuance or declaration of cash or stock dividends or other distributions with respect to such class of Actively Traded Marathon Equity Securities, in each case at any time during the ten full Trading Day period referred to above, Marathon and Ashland shall make such adjustment to the Fair Market Value of such Actively Traded Equity Securities determined pursuant to this Section 7.03(a) as Marathon and Ashland shall mutually agree so as to preserve the economic benefits to Ashland expected on the date of this Agreement as a result of the issuance to it of such Actively Traded Marathon Equity Securities as part of the Ashland Put Price.

(b) Fair Market Value Where There is a Holding Period. In the event that Marathon elects pursuant to Section 4.04(a) or 4.04(b) to impose a Holding Period on any Actively Traded Marathon Equity Securities, the Fair Market Value of such Actively Traded Marathon Equity Securities shall be deemed to be an amount equal to (i) the Fair Market Value of such Actively Traded Marathon Equity Securities as determined pursuant to Section 7.03(a), minus (ii) a discount factor that takes into account such limitation on Ashland’s ability to freely trade such Actively Traded Marathon Equity Securities (a “7.03(b) Discount Amount”). The 7.03(b) Discount Amount with respect to the Fair Market Value of such Actively Traded Marathon Equity Securities shall be determined pursuant to the following procedures:

(i) Negotiation Period. For a period of 15 days following the applicable Ashland Put Price Election Date, Marathon and Ashland will negotiate in good faith to seek to reach an agreement as to the 7.03(b)

Discount Amount. If Marathon and Ashland reach such an agreement, then the 7.03(b) Discount Amount shall be deemed to be the amount so agreed upon by Marathon and Ashland.

(ii) Appraisal Process. In the event Marathon and Ashland are unable to reach an agreement as to the 7.03(b) Discount Amount within the 15-day period referred to in clause (i) above, then within five Business Days after the expiration of such 15-day period (such fifth Business Day being referred to herein as the “7.03(b) Appraisal Process Commencement Date”), Marathon and Ashland each shall select a nationally recognized investment banking firm to (A) prepare a report which (1) sets forth such investment banking firm’s determination of the 7.03(b) Discount Amount (which shall be a single amount as opposed to a range) and (2) includes work papers which indicate the basis for and the calculation of the 7.03(b) Discount Amount (a “7.03(b) Appraisal Report”) and (B) deliver to Marathon or Ashland, as the case may be, an oral and written opinion addressed to such party as to the 7.03(b) Discount Amount. The fees and expenses of each investment banking firm shall be paid by the party selecting such investment banking firm. Each of Marathon and Ashland shall instruct its respective investment banking firm to (i) not consult with the other investment banking firm with respect to its view as to the 7.03(b) Discount Amount prior to the time that both investment banking firms have delivered their respective opinions to Marathon and Ashland, as applicable, (ii) deliver their respective 7.03(b) Appraisal Reports, together with their oral and written opinions as to the 7.03(b) Discount Amount (the “7.03(b) Initial Opinion Values”), within 15 days after the 7.03(b) Appraisal Process Commencement Date, and (iii) deliver a copy of its written opinion and its 7.03(b) Appraisal Report to the Company, the other party and the other party’s investment banking firm at the time it delivers its oral and written opinion to Marathon or Ashland, as applicable.

If the 7.03(b) Initial Opinion Values differ and the lesser 7.03(b) Initial Opinion Value equals or exceeds 90% of the greater 7.03(b) Initial Opinion Value, the 7.03(b) Discount Amount shall be deemed to

be an amount equal to (1) the sum of the 7.03(b) Initial Opinion Values divided by (2) two.

If the 7.03(b) Initial Opinion Values differ and the lesser 7.03(b) Initial Opinion Value is less than 90% of the greater 7.03(b) Initial Opinion Value, then:

(i) within two Business Days after both investment banking firms have delivered their respective opinions to Marathon or Ashland, as applicable, each investment banking firm shall, at a single meeting at which Marathon, Ashland, the Company and the other investment banking firm are present, make a presentation with respect to its 7.03(b) Initial Opinion Value. At such presentation, Marathon, Ashland, the Company and the other investment banking firm shall be entitled to ask questions as to the basis for and the calculation of such investment banking firm’s 7.03(b) Initial Opinion Value; and

(ii) Marathon and Ashland shall, within five Business Days after the date Marathon and Ashland receive the 7.03(b) Initial Opinion Values (such fifth Business Day being referred to herein as the “7.03(b) Subsequent Appraisal Process Commencement Date”), jointly select a third nationally recognized investment banking firm to (i) prepare a 7.03(b) Appraisal Report and (ii) deliver an oral and written opinion addressed to Marathon and Ashland as to the 7.03(b) Discount Amount. The fees and expenses of such third investment banking firm shall be paid 50% by Marathon and 50% by Ashland. Such third investment banking firm shall not be provided with the 7.03(b) Initial Opinion Values and shall not consult with the initial investment banking firms with respect thereto. During such five-Business Day period, Marathon and Ashland shall negotiate in good faith to independently reach an agreement as to the 7.03(b) Discount Amount. If Marathon and Ashland reach such an agreement, then the 7.03(b) Discount Amount shall be deemed to be the amount so agreed upon by Marathon and Ashland. If Marathon and Ashland are unable to reach such an agreement, then Marathon and Ashland shall instruct such third investment banking firm to deliver its 7.03(b) Appraisal Report, together with its oral and written opinion as to the 7.03(b) Discount Amount (the “7.03(b) Third Opinion Value”),

within 15 days after the 7.03(b) Subsequent Appraisal Process Commencement Date. The 7.03(b) Discount Amount in such circumstance shall be deemed to be an amount equal to (1) the sum of (x) the 7.03(b) Third Opinion Value plus (y) whichever of the two 7.03(b) Initial Opinion Values is closer to the 7.03(b) Third Opinion Value (or, if the 7.03(b) Third Opinion Value is exactly halfway between the two 7.03(b) Initial Opinion Values, the 7.03(b) Third Opinion Value), divided by (2) two.

SECTION 7.04. Determination of Fair Market Value of Non-Actively Traded Marathon Equity Securities. (a) Negotiation Period. If Marathon proposes to issue (or to have issued) to Ashland Marathon Equity Securities that are not Actively Traded Marathon Equity Securities, then for a period of 15 days following the applicable Ashland Put Price Election Date, Marathon and Ashland will negotiate in good faith to seek to reach an agreement as to the Fair Market Value of such Marathon Equity Securities, taking into account, if there is a Holding Period, a discount factor that takes into account such limitation on Ashland’s ability to freely trade such Marathon Equity Securities (a “7.04 Discount Amount”). If Marathon and Ashland reach such an agreement, then the Fair Market Value of such Marathon Equity Securities shall be deemed to be the amount so agreed upon by Marathon and Ashland.

(b) Appraisal Process. In the event Marathon and Ashland are unable to reach an agreement as to such Fair Market Value of Marathon Equity Securities and such 7.04 Discount Amount, if any, within the 15-day period referred to in clause (a) above, then within five Business Days after the expiration of such 15-day period (such fifth Business Day being referred to herein as the “7.04 Appraisal Process Commencement Date”), Marathon and Ashland each shall select a nationally recognized investment banking firm to (i) prepare a report which (1) sets forth such investment banking firm’s determination of the Fair Market Value of such Marathon Equity Securities (which shall be a single amount as opposed to a range), taking into account, if there is a Holding Period, a 7.04 Discount Amount, which is determined by such investment banking firm, and (2) includes work papers which separately indicate the basis for and the calculation of the Fair Market Value of such Marathon Equity Securities and, if there is a Holding Period, the basis for and the calculation of the 7.04 Discount Amount (a “7.04

Appraisal Report”) and (ii) deliver to Marathon or Ashland, as the case may be, an oral and written opinion addressed to such party as to the Fair Market Value of such Marathon Equity Securities (which opinion shall take into account a 7.04 Discount Amount if there is a Holding Period with respect to such Marathon Equity Securities). The fees and expenses of each investment banking firm shall be paid by the party selecting such investment banking firm. Each of Marathon and Ashland shall instruct its respective investment banking firm to (i) not consult with the other investment banking firm with respect to its view as to the Fair Market Value of such Marathon Equity Securities and the 7.04 Discount Amount prior to the time that both investment banking firms have delivered their respective opinions to Marathon and Ashland, as applicable, (ii) deliver their respective 7.04 Appraisal Reports, together with their oral and written opinions as to the Fair Market Value of such Marathon Equity Securities (the “7.04 Initial Opinion Values”), within 15 days after the 7.04 Appraisal Process Commencement Date, and (iii) deliver a copy of its written opinion and its 7.04 Appraisal Report to the Company, the other party and the other party’s investment banking firm at the time it delivers its oral and written opinion to Marathon or Ashland, as applicable.

If the 7.04 Initial Opinion Values differ and the lesser 7.04 Initial Opinion Value equals or exceeds 90% of the greater 7.04 Initial Opinion Value, the Fair Market Value of such Marathon Equity Securities shall be deemed to be an amount equal to (1) the sum of the 7.04 Initial Opinion Values divided by (2) two.

If the 7.04 Initial Opinion Values differ and the lesser 7.04 Initial Opinion Value is less than 90% of the greater 7.04 Initial Opinion Value, then:

(i) within two Business Days after both investment banking firms have delivered their respective opinions to Marathon or Ashland, as applicable, each investment banking firm shall, at a single meeting at which Marathon, Ashland, the Company and the other investment banking firm are present, make a presentation with respect to its 7.04 Initial Opinion Value. At such presentation, Marathon, Ashland, the Company and the other investment banking firm shall be entitled to ask questions as to the basis for and the calculation of

(ii) Marathon and Ashland shall, within five Business Days after the date Marathon and Ashland receive the 7.04 Initial Opinion Values (such fifth Business Day being referred to herein as the “7.04 Subsequent Appraisal Process Commencement Date”), jointly select a third nationally recognized investment banking firm to (i) prepare a 7.04 Appraisal Report and (ii) deliver an oral and written opinion addressed to Marathon and Ashland as to the Fair Market Value of such Marathon Equity Securities (which opinion shall take into account a 7.04 Discount Amount if there is a Holding Period with respect to such Marathon Equity Securities). The fees and expenses of such third investment banking firm shall be paid 50% by Marathon and 50% by Ashland. Such third investment banking firm shall not be provided with the 7.04 Initial Opinion Values and shall not consult with the initial investment banking firms with respect thereto. During such five-Business Day period, Marathon and Ashland shall negotiate in good faith to independently reach an agreement as to the Fair Market Value of such Marathon Equity Securities. If Marathon and Ashland reach such an agreement, then the Fair Market Value of such Marathon Equity Securities shall be deemed to be the amount so agreed upon by Marathon and Ashland. If Marathon and Ashland are unable to reach such an agreement, then Marathon and Ashland shall instruct such third investment banking firm to deliver its 7.04 Appraisal Report, together with its oral and written opinion as to the Fair Market Value of such Marathon Equity Securities (the “7.04 Third Opinion Value”), within 15 days after the 7.04 Subsequent Appraisal Process Commencement Date. The Fair Market Value of such Marathon Equity Securities in such circumstance shall be deemed to be an amount equal to (i) the sum of (x) the 7.04 Third Opinion Value plus (y) whichever of the two 7.04 Initial Opinion Values is closer to the 7.04 Third Opinion Value (or, if the 7.04 Third Opinion Value is exactly halfway between the two 7.04 Initial Opinion Values, the 7.04 Third Opinion Value), divided by (ii) two.

Marathon from the Company in accordance with the provisions of Section 5.01(a)(ii), together with interest on each such Exercise Period Distribution at a rate per annum equal to the Base Rate, with daily accrual of interest, from (but excluding) the date such amount was otherwise payable to Ashland (or, if earlier, the date such amount was paid to Marathon) to (and including) the date such amount is paid to Ashland in accordance with the provisions of this clause (iii); (iv) the Company shall immediately release to Ashland all amounts then held in the Escrow Account, including any income earned thereon; and (v) if the Closing shall not have occurred on or prior to the date that is 180 days after the Scheduled Closing Date, Ashland thereafter shall have the right, exercisable at any time prior to the Closing by written notice to Marathon, to revoke its Ashland Put Exercise Notice or Marathon’s Marathon Call Exercise Notice, as applicable.

(b) Adjustments to Ashland Put Price or Marathon Call Price. In addition, if the Closing of the Marathon Call Right or the Ashland Put Right does not occur on the Scheduled Closing Date, and (i) the delay is due to (x) a failure by Marathon or USX to timely perform in any material respect any of its respective covenants and agreements contained herein or (y) the fact that any of Marathon’s or USX’s respective representations and warranties contained herein have ceased to be true and correct in any material respect, and (ii) Ashland shall not have (x) failed to timely perform in any material respect any of its covenants and agreements contained herein or (y) breached any of its representations and warranties contained herein in any material respect, then Marathon shall be entitled to deduct from the Marathon Call Price or from the Ashland Put Price (or the first Installment Payment, as applicable) payable to Ashland on the Delayed Closing Date, an amount (the “9.04(b) Post-Scheduled Closing Date Distribution Amount”) equal to the amount of any Ashland Exercise Period Distributions that Ashland shall have received from the Company in Cash during the Delayed Closing Date Interest Period and, on the Delayed Closing Date, Marathon shall pay to Ashland in addition to the Marathon Call Price or the Ashland Put Price (or the first Installment Payment, as applicable) and related accrued interest payable pursuant to Section 3.01 or 4.01, as applicable, an amount in Cash equal to the amount of interest accrued during the Delayed Closing Interest Period on an amount equal to (1) the Marathon Call Price or the Ashland Put Price (or the first Installment Payment thereof,

as applicable) minus (2) the 9.04(b) Post-Scheduled Closing Date Distribution Amount, at a rate per annum equal to the 30-day LIBOR Rate multiplied by 1.5, with daily accrual of interest.

(c) Other Consequences. In the event that Ashland revokes its Ashland Put Exercise Notice or Marathon’s Marathon Call Exercise Notice pursuant to clause (v) of Section 9.03(a), each of Ashland and Marathon shall thereafter have the right to exercise their respective Ashland Put Right and Marathon Call Right in accordance with the terms of this Agreement. Any such revocation shall not operate as a release of Marathon or USX from any liability it may have to Ashland for any breach of its obligations under this Agreement and such revocation shall not in any way preclude Ashland from exercising any right or power hereunder or otherwise available to it at law or in equity as a result of any such breach.

SECTION 9.05. Consequences of a Delayed Closing of the Marathon Call Right or the Ashland Put Right Where No Party Is at Fault. If the Closing of the Marathon Call Right or the Ashland Put Right does not occur on the Scheduled Closing Date, and the delay is not due to a failure by any party hereto to timely perform in any material respect any of its respective covenants and agreements contained herein or to the fact that any party’s representations and warranties contained herein have ceased to be true and correct in any material respect, then Marathon shall pay to Ashland on the Delayed Closing Date, in addition to the Marathon Call Price or the Ashland Put Price (or the first Installment Payment, as applicable) and related accrued interest payable pursuant to Section 3.01 or 4.01, as applicable, an amount in Cash equal to the amount of interest accrued during the Delayed Closing Interest Period on the Marathon Call Price or the Ashland Put Price (or the first Installment Payment, as applicable), at a rate per annum equal to the Base Rate, with daily accrual of interest. If the Delayed Closing Date does not occur on or prior to the date that is 180 days after the Scheduled Closing Date and the delay is not due to an action or failure to act by any of Marathon, USX or Ashland, then (i) effective as of 12:01 a.m. on the day immediately following the last day of such 180-day period, all Ashland Representatives Revocable Proxies and the Ashland LOOP/LOCAP Revocable Proxy shall automatically be revoked; (ii) Marathon shall, and shall cause each of its

Representatives to, promptly take all such actions as are necessary to provide that the Company shall resume making distributions of Distributable Cash and Tax Liability Distributions directly to Ashland pursuant to Article V of the LLC Agreement; (iii) Marathon shall immediately pay to Ashland an amount equal to all Exercise Period Distributions received by Marathon from the Company in accordance with the provisions of Section 5.01(a)(ii), together with interest on each such Exercise Period Distribution at a rate per annum equal to the Base Rate, with daily accrual of interest, from (but excluding) the date such amount was otherwise payable to Ashland (or, if earlier, the date such amount was paid to Marathon) to (and including) the date such amount is paid to Ashland in accordance with the provisions of this clause (iii); (iv) the Company shall immediately release to Ashland all amounts then held in the Escrow Account, including any income earned thereon; and (v) the parties shall be restored to their rights as though the Ashland Put Right or the Marathon Call Right had never been exercised, without liability to any party and without any effect on the ability of Ashland to exercise its Ashland Put Right or Marathon to exercise its Marathon Call Right in accordance with the terms of this Agreement in the future.

SECTION 9.06. Consequences of Delayed Second or Third Scheduled Installment Payment. If Marathon shall fail to make an Installment Payment on the second or third Scheduled Installment Payment Date, if applicable, then on such later date on which the applicable Installment Payment is actually made (such later date being a “Delayed Installment Payment Date”), Marathon shall pay to Ashland, in addition to the applicable Installment Payment and related accrued interest payable pursuant to Section 3.01 or 4.01, as applicable, an amount in Cash equal to the amount of interest accrued during the period commencing on the day immediately following the Scheduled Installment Payment Date and ending on and including the date of the payment of the relevant Installment Payment (the “Delayed Installment Payment Date Interest Period”) on the applicable Installment Payment, at a rate per annum equal to the 30 day LIBOR Rate multiplied by 1.5, with daily accrual of interest.

SECTION 9.07. Consequences of a Delayed Closing of the Special Termination Right Where Terminating Member Is at Fault. (a) Continuation of Term of the Company; Right to Specific Performance. If the Closing of the Special Termination Right shall not have occurred on or prior to the

Scheduled Closing Date, and (i) the delay is due to (x) a failure by the Terminating Member (or, if Marathon is the Terminating Member, Marathon or USX) to timely perform in any material respect any of its covenants and agreements contained herein or (y) the fact that any of the Terminating Member’s (or, if Marathon is the Terminating Member, Marathon’s or USX’s) representations and warranties contained herein have ceased to be true and correct in any material respect, and (ii) the Non-Terminating Member (or, if Marathon is the Non- Terminating Member, Marathon or USX) shall not have (x) failed to timely perform in any material respect any of its covenants and agreements contained herein or (y) breached any of its representations and warranties contained herein in any material respect, then the Non-Terminating Member shall have the right to elect, by written notice to the Company and the Terminating Member, to either (i) terminate the Term of the Company at the end of the Initial Term or the then- current 10-year extension thereof, as applicable (in which case the Term of the Company shall automatically terminate upon the expiration of the Initial Term or the then-current 10-year extension thereof), or (ii) extend the Term of the Company for two additional years following the expiration of the Initial Term or the then-current 10-year extension thereof, as applicable (in which case the Term of the Company shall automatically be extended for such additional two-year period).

(b) Adjustment to Special Termination Price. If the Closing of the Special Termination Right does not occur on the Scheduled Closing Date, and (i) the delay is due to (x) a failure by the Terminating Member (or, if Marathon is the Terminating Member, Marathon or USX) to timely perform in any material respect any of its covenants and agreements contained herein or (y) the fact that any of the Terminating Member’s (or, if Marathon is the Terminating Member, Marathon’s or USX’s) representations and warranties contained herein have ceased to be true and correct in any material respect, and (ii) the Non-Terminating Member (or, if Marathon is the Terminating Member, Marathon or USX) shall not have (x) failed to timely perform in any material respect any of its covenants and agreements contained herein or (y) breached any of its representations and warranties contained herein in any material respect, then on the Delayed Closing Date the Non-Terminating Member shall deduct from the Special Termination Price payable to the Terminating Member on the Delayed Closing Date, an amount equal to the amount of interest accrued during the Delayed

Closing Date Interest Period on the Special Termination Price, at a rate per annum equal to the 30-day LIBOR Rate multiplied by 1.5, with daily accrual of interest.

SECTION 9.08. Consequences of a Delayed Closing of the Special Termination Right Where Non-Terminating Member Is at Fault.(a) Revocation of Proxies; Payment of Distributions to Terminating Member; Right to Revoke Special Termination Exercise Notice. If the Closing of the Special Termination Right does not occur on the Scheduled Closing Date, and (i) the delay is due to a failure by the Non-Terminating Member (or, if Marathon is the Non-Terminating Member, Marathon or USX) to timely perform in any material respect any of its covenants and agreements contained herein or (y) the fact that any of the Non- Terminating Member’s (or, if Marathon is the Non-Terminating Member, Marathon’s or USX’s) representations and warranties contained herein have ceased to be true and correct in any material respect, and (ii) the Terminating Member (or, if Marathon is the Terminating Member, Marathon or USX) shall not have (x) failed to timely perform in any material respect any of its covenants and agreements contained herein or (y) breached any of its representations and warranties contained herein in any material respect, then (i) effective as of 12:01 a.m. on the day immediately following the Scheduled Closing Date, all Marathon Representative Revocable Proxies (in the circumstance where Marathon is the Terminating Member) or all Ashland Representative Revocable Proxies and the Ashland LOOP/LOCAP Revocable Proxy (in the circumstance where Ashland is the Terminating Member) shall automatically be revoked; (ii) the Non-Terminating Member shall, and shall cause each of its Representatives to, promptly take all such actions as are necessary to provide that the Company shall thereupon resume making distributions of Distributable Cash and Tax Liability Distributions directly to the Terminating Member pursuant to Article V of the LLC Agreement; (iii) the Non-Terminating Member shall immediately pay to the Terminating Member an amount equal to all Exercise Period Distributions received by the Non- Terminating Member from the Company in accordance with the provisions of Section 5.01(a)(ii) or Section 5.01(b)(ii), as applicable, together with interest on each such Exercise Period Distribution at a rate per annum equal to the Base Rate, with daily accrual of interest, from (but excluding) the date such amount was otherwise payable to the Terminating Member (or, if earlier, the date such amount was paid to the Non-Terminating Member) to (and including) the

date such amount is paid to the Terminating Member in accordance with the provisions of this clause (iii); (iv) the Company shall immediately release to the Terminating Member all amounts then held in the Escrow Account, including any income earned thereon; and (v) if the Closing shall not have occurred on or prior to the date that is 120 days before the expiration of the Initial Term or the then-current 10-year extension thereof, each of the Terminating Member and the Non-Terminating Member thereafter shall have the right, exercisable at any time prior to the Closing by written notice to the other party, to revoke the Non-Terminating Member’s Special Termination Exercise Notice, in which event the Term of the Company shall automatically terminate upon the expiration of the Initial Term or the then-current 10-year extension thereof.

(b) Adjustments to Special Termination Price. In addition, if the Closing of the Special Termination Right does not occur on the Scheduled Closing Date, and (i) the delay is due to (x) a failure by the Non-Terminating Member (or, if Marathon is the Non-Terminating Member, Marathon or USX) to timely perform in any material respect any of its covenants and agreements contained herein or (y) the fact that any of the Non-Terminating Member’s (or, if Marathon is the Non-Terminating Member, Marathon’s or USX’s) representations and warranties contained herein have ceased to be true and correct in any material respect, and (ii) the Terminating Member (or, if Marathon is the Terminating Member, Marathon or USX) shall not have (x) failed to timely perform in any material respect any of its covenants and agreements contained herein or (y) breached any of its representations and warranties contained herein in any material respect, then the Non-Terminating Member shall be entitled to deduct from the Special Termination Price payable to the Terminating Member on the Delayed Closing Date, an amount (the “9.08(b) Post-Scheduled Closing Date Distribution Amount”) equal to the amount of any Exercise Period Distributions that the Terminating Member shall have received from the Company in Cash during the Delayed Closing Date Interest Period and, on the Delayed Closing Date, the Non-Terminating Member shall pay to the Terminating Member in addition to the Special Termination Price and related accrued interest payable pursuant to Section 2.01, an amount in Cash equal to the amount of interest accrued during the Delayed Closing Interest Period on an amount equal to (1) the Special Termination Price minus (2) the 9.08(b) Post-Scheduled Closing Date Distribution Amount, at a rate

per annum equal to the 30-day LIBOR Rate multiplied by 1.5, with daily accrual of interest.

(c) Other Consequences. In the event that the Terminating Member revokes the Non-Terminating Member’s Special Termination Exercise Notice, then the Non-Terminating Member shall not thereafter have the right to exercise its Special Termination Right. Any such revocation shall not operate as a release of the Non-Terminating Member from any liability it may have to the Terminating Member for any breach of its obligations under this Agreement and such revocation shall not in any way preclude the Terminating Member from exercising any right or power hereunder or otherwise available to it at law or in equity as a result of any such breach.

SECTION 9.09. Consequences of Delayed Closing of Special Termination Right Where No Party Is at Fault. If the Closing of the Special Termination Right does not occur on the Scheduled Closing Date, and the delay is not due to a failure by any party hereto to timely perform in any material respect any of its respective covenants and agreements contained herein or to the fact that any party’s representations and warranties contained herein have ceased to be true and correct in any material respect, then the Non-Terminating Member shall pay to the Terminating Member on the Delayed Closing Date, in addition to the Special Termination Price and related accrued interest payable pursuant to Section 2.01, an amount in Cash equal to the amount of interest accrued during the Delayed Closing Interest Period on the Special Termination Price, at a rate per annum equal to the Base Rate, with daily accrual of interest. If the Delayed Closing Date does not occur on or prior to the date that is 120 days before the expiration of the Initial Term or the then-current 10-year extension thereof and the delay is not due to an action or failure to act by the Terminating Member or the Non-Terminating Member, then (i) effective as of 12:01 a.m. on the day immediately following such 120th day before the expiration of the Initial Term or the then-current 10-year extension thereof, all Marathon Representative Revocable Proxies (in the circumstance where Marathon is the Terminating Member) or all Ashland Representative Revocable Proxies and the Ashland LOOP/LOCAP Revocable Proxy (in the circumstance where Ashland is the Terminating Member) shall be revoked; (ii) the Non-Terminating Member shall, and shall cause each of its Representatives to, promptly take all such actions as

are necessary to provide that the Company shall resume making distributions of Distributable Cash and Tax Liability Distributions directly to the Terminating Member pursuant to Article V of the LLC Agreement; (iii) the Non-Terminating Member shall immediately pay to the Terminating Member an amount equal to all Exercise Period Distributions received by the Non-Terminating Member from the Company in accordance with the provisions of Section 5.01(a)(ii) or Section 5.01(b)(ii), as applicable, together with interest on each such Exercise Period Distribution at a rate per annum equal to the Base Rate, with daily accrual of interest, from (but excluding) the date such amount was otherwise payable to the Terminating Member (or, if earlier, the date such amount was paid to the Non- Terminating Member) to (and including) the date such amount is paid to the Terminating Member in accordance with the provisions of this clause (iii); (iv) the Company shall immediately release to the Terminating Member all amounts then held in the Escrow Account, including any income earned thereon; and (v) the Term of the Company shall automatically terminate upon the expiration of the Initial Term or the then-current 10-year extension thereof.

SECTION 10.01. Registration upon Request. (a) Ashland shall have the right to make a written demand upon the issuer or, in the case of any Marathon Debt Securities issued by Marathon and guaranteed by USX, issuers of any class of Securities delivered or to be delivered to Ashland as payment of any portion of the Ashland Put Price (both parties hereinafter referred to collectively as the “Issuer”), on not more than six separate occasions (subject to the provisions of this Section 10.01), to either, at Ashland’s option, (i) register under the Securities Act all or a portion of such Securities for purposes of a public offering by Ashland of such Securities or (ii) prepare an Offering Memorandum that covers all or a portion of such Securities for purposes of a private placement by Ashland of such Securities (either of such requests being referred to herein as a “Demand Registration”) that were not registered under the Securities Act at the time of issuance thereof to Ashland on the Closing Date or Installment Payment Date, as the case may be, and the Issuer shall use its best efforts

to file a Registration Statement and cause such Securities to be registered under the Securities Act (in the case of a Demand Registration for a public offering) or to prepare a final Offering Memorandum (in the case of a Demand Registration for a private placement) (i) in the case of any Securities to be delivered to Ashland on the Closing Date or any Installment Payment Date, not later than the Scheduled Closing Date or applicable Scheduled Installment Payment Date or (ii) in the case of any Securities that have been delivered to Ashland on the Closing Date or any Installment Payment Date, in each case not later than 60 days after such written demand by Ashland; provided that each Demand Registration shall cover Securities having an aggregate fair market value (based on the then-current market value of such Securities or, if such market value cannot be determined, based on the expected offering price of such Securities) equal to (i) in the case of a public offering, $100 million or more, unless Ashland shall hold less than $100 million of Securities, in which event, the remaining Securities held by Ashland and (ii) in the case of a private placement, $25 million or more, unless Ashland shall hold less than $25 million of Securities, in which event, the remaining Securities held by Ashland.

(b) Notwithstanding the provisions of Section 10.01(a), the Issuer (i) shall not be obligated to prepare or file more than one Registration Statement pursuant to this Section 10.01 during any six month period (measured from the effective date (or, in the case of a private placement, the closing date) of the most recently requested Demand Registration to the date of the demand by Ashland for a subsequent Demand Registration) and (ii) shall be entitled to postpone the filing of any Registration Statement otherwise required to be prepared and filed by it pursuant to Section 10.01(a), and to prevent Ashland from initially distributing any Offering Memorandum required to be prepared by the Issuer pursuant to Section 10.01(a), in each case (x) if the Issuer is actively pursuing an Underwritten Public Offering, for a period of up to 90 days following the closing of any Underwritten Public Offering; provided that the Issuer is advised by its managing underwriter or underwriters in writing (with a copy to Ashland), that the price at which securities would be offered in such offering would, in its or in their opinion, be materially adversely affected by the registration or the initial dissemination of the Offering Memorandum so requested, or (y) for a period of up to 90 days if the

Issuer determines in its reasonable judgment and in good faith that the registration and distribution of such Securities (or the private placement thereof, in the case of a sale by Ashland of such securities pursuant to Section 4(2) or Rule 144A of the Securities Act) would materially adversely impair or interfere with in any material respect any contemplated material financing, acquisition, disposition, corporate reorganization or other similar transaction involving the Issuer or any of its subsidiaries or Affiliates ((x) or (y) being hereinafter referred to as a “Blackout Period”), provided, however, that the aggregate number of days included in all Blackout Periods during any consecutive 12 months shall not exceed 180 days, and; provided further, however, that a period of at least 30 days shall elapse between the termination of any Blackout Period and the commencement of the immediately succeeding Blackout Period. In the event of such postponement, Ashland shall have the right to withdraw such request for registration or request for preparation of an Offering Memorandum by giving written notice to the Issuer within 20 days after receipt of notice of postponement and, in the event of such withdrawal, such request shall not be counted for purposes of determining the number of Demand Registrations to which Ashland is entitled pursuant to Section 10.01(a).

(c) A registration requested pursuant to this Section 10.01 shall not be deemed to have been effected unless the Registration Statement relating thereto (i) has become effective under the Securities Act and (ii) has remained effective for a period of at least 90 days (or such shorter period in which all Securities included in such registration have actually been sold thereunder); provided, however, that if after any Registration Statement requested pursuant to this Section 10.01 becomes effective such Registration Statement is interfered with by any stop order, injunction or other order or requirement of the Commission or other Governmental Authority solely due to the actions or omissions to act of the Issuer prior to being effective for 90 days and less than 75% of the Securities have been sold thereunder, such Registration Statement shall be at the sole expense of the Issuer and shall not constitute a Demand Registration. In addition, a request for the preparation of an Offering Memorandum pursuant to this Section 10.01 shall not be deemed to have been effected unless the information contained in such Offering Memorandum has remained “reasonably current” (as such term is defined in Rule 144A

under the Securities Act) for a period of at least 90 days (or such shorter period in which all Securities covered by such Offering Memorandum have actually been sold thereunder); provided, however, that if such Offering Memorandum is interfered with by any stop order, injunction or other order or requirement of the Commission or other Governmental Authority solely due to the actions or omissions to act of the Issuer prior to such Offering Memorandum being made available to Ashland for 90 days and less than 75% of the Securities have been sold pursuant thereto, such Offering Memorandum shall be at the sole expense of the Issuer and shall not constitute a Demand Registration.

(d) On or after the date hereof, the Issuer shall not grant to any other holder of its securities, whether currently outstanding or issued in the future, any incidental or “piggy-back” registration rights with respect to any Registration Statement filed or Offering Memorandum prepared pursuant to a Demand Registration under this Section 10.01 and, without the prior consent of Ashland, will not permit any holder of its securities to participate in any offering or private placement made pursuant to a Demand Registration under this Section 10.01.

(e) If a Demand Registration involves an Underwritten Public Offering and the managing underwriter or underwriters shall advise the Issuer and Ashland in writing that, in its view, the number of securities requested to be included in such registration (including, without limitation, Securities requested to be included by Ashland, securities which the Issuer proposes to be included, and securities proposed to be included by other holders of securities entitled to include securities in such registration pursuant to incidental or “piggy-back” registration rights other than those pursuant to this Article X (the “Other Holders”)) exceeds the largest number of shares of securities which can be sold without having an adverse effect on such offering, including the price at which such securities can be sold (the “Maximum Offering Size”), the Issuer shall include in such registration, in the priority listed below, up to the Maximum Offering Size:

(ii) second, all securities requested to be included in such registration by any Other Holder (allocated, if necessary, for the offering not to exceed the Maximum Offering Size, pro rata among such Other Holders on the basis of the relative number of securities requested to be included in such registration); and

(iii) third, any securities proposed to be registered by the Issuer or by any Other Holders pursuant to incidental or “piggy-back” registration rights.

(f) Ashland may, at any time, prior to the effective date of the Registration Statement or the initial distribution of the Offering Memorandum relating to such request, revoke such request by providing a written notice to the Issuer, in which case such request, as so revoked, shall not constitute a Demand Registration.

SECTION 10.02. Covenants of the Issuer. (a) Registration Statement Covenants.

intended methods of disposition by Ashland set forth in such Registration Statement and (ii) the expiration of 90 days after the date such Registration Statement becomes effective; provided that before filing a Registration Statement or prospectus, or any amendments or supplements thereto, the Issuer shall furnish to Ashland and its counsel, copies of all documents proposed to be filed;

(7) otherwise use its best efforts to comply with all applicable rules and regulations of the Commission, and make available to Ashland, as soon as reasonably practicable (but not more than eighteen months) after the effective date of the Registration Statement, an earnings statement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations promulgated thereunder;

(8) use its best efforts to cause all such Securities that are Marathon Equity Securities to be listed on any securities exchange on which the securities of the Issuer are then listed, if such Securities are not already so listed and if such listing is then permitted under the rules of such exchange, and to provide a transfer agent and registrar for such Securities covered by such Registration Statement no later than the effective date of such Registration Statement;

(b) Offering Memorandum Covenants. In the event that any Securities are to be sold by Ashland by means of an Offering Memorandum prepared by the Issuer pursuant to Sections 10.01, the Issuer covenants and agrees that it shall (i) cooperate in the sale of the Securities and (ii) as expeditiously as possible:

(3) furnish to Ashland such number of copies of such Offering Memorandum and of each amendment and supplement thereto (in each case including all exhibits), and such other documents as Ashland may reasonably request in order to facilitate the disposition of the Securities by Ashland;

(4) use its best efforts to register or qualify such Securities covered by such Offering Memorandum under such other securities or blue sky laws of such jurisdictions as Ashland shall reasonably request, and do any and all other acts and things which may be reasonably necessary or advisable to enable Ashland to consummate the disposition in such jurisdictions of the Securities owned by Ashland, except that the Issuer shall not for any such purpose be required to (i) qualify generally to do business as a foreign corporation in any jurisdiction where, but for the requirements of this Section 10.02(b)(4), it would not be obligated to be so qualified, (ii) subject itself to

(7) otherwise use its best efforts to comply with all applicable rules and regulations of the Commission;

In the case of any offering registered pursuant to this Article X or any private placement pursuant to an Offering Memorandum prepared by the Issuer pursuant to this Article X, the Issuer agrees to indemnify and hold Ashland, each underwriter or initial purchaser, if any, of the Securities under such registration or covered by such Offering Memorandum and each person who controls any of the foregoing within the meaning of Section 15 of the Securities Act, and any director, officer, employee, stockholder, partner, agent or representative, of the foregoing, harmless against any and all losses, claims, damages or liabilities (including reasonable legal fees and other reasonable expenses incurred in the investigation and defense thereof) (collectively “Losses”) to which they or any of them may become subject under the Securities Act or otherwise, insofar as any such Losses shall arise out of or shall be based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (as amended if the Issuer shall have filed with the Commission any amendment thereof) or Offering Memorandum (as amended if the Issuer shall have prepared and delivered to Ashland for private distribution any amendment to such Offering Memorandum), or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in the prospectus relating to the sale of such Securities (as amended or supplemented if the Issuer shall have filed with the Commission any amendment

thereof or supplement thereto), or the omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided that the indemnification contained in this Section 10.04 shall not apply to such Losses which shall arise out of or shall be based upon any such untrue statement or alleged untrue statement, or any such omission or alleged omission, which shall have been made in reliance upon and in conformity with information furnished in writing to the Issuer by Ashland or such underwriter or initial purchaser, as the case may be, specifically for use in connection with the preparation of the Registration Statement, the prospectus contained in the Registration Statement or the Offering Memorandum, as applicable, or any such amendment thereof or supplement therein.

Notwithstanding the foregoing provisions of this Section 10.04, the Issuer shall not be liable to Ashland, any person who participates as an underwriter in the offering or sale of such Securities, any person who participates as an initial purchaser in the private placement of such Securities or any other person, if any, who controls Ashland or any underwriter or initial purchaser (within the meaning of the Securities Act), under the indemnity agreement in this Section 10.04 for any such Losses that arise out of Ashland’s or such other person’s failure to send or give a copy of the final prospectus or final Offering Memorandum to the person asserting an untrue statement or alleged untrue statement or omission or alleged omission at or prior to the written confirmation of the sale of the Securities to such person if such statement or omission was corrected in such final prospectus or final Offering Memorandum and the Issuer has previously furnished copies thereof in accordance with this Agreement.

In the case of each offering registered pursuant to this Article X and each private placement pursuant to this Article X, Ashland shall agree, and each underwriter or initial purchaser, if any, participating therein shall agree, substantially in the same manner and to the same extent as set forth in the preceding paragraph, severally to indemnify and hold harmless the Issuer and each person who controls the Issuer within the meaning of Section 15 of the Securities Act, and any director, officer, employee, stockholder, partner, agent or representative of the Issuer, with respect to any statement in or omission from such

Registration Statement (as amended or as supplemented, if amended or supplemented as aforesaid) or Offering Memorandum (as amended or as supplemented, if amended or supplemented as aforesaid), as applicable, if such statement or omission shall have been made in reliance upon and in conformity with information furnished in writing to the Issuer by Ashland or such underwriter or initial purchaser, as the case may be, specifically for use in connection with the Registration Statement, the prospectus contained in such Registration Statement or the Offering Memorandum, as applicable, or any such amendment thereof or supplement thereto.

Each party indemnified under this Section 10.04 shall, promptly after receipt of notice of the commencement of any claim against any such indemnified party in respect of which indemnity may be sought hereunder, notify the indemnifying party in writing of the commencement thereof. The failure of any indemnified party to so notify an indemnifying party of any action shall not relieve the indemnifying party from any liability in respect of such action which it may have to such indemnified party on account of the indemnity contained in this Section 10.04, unless (and only to the extent) the indemnifying party was prejudiced by such failure, and in no event shall such failure relieve the indemnifying party from any other liability which it may have to such indemnified party. In case any action in respect of which indemnification may be sought hereunder shall be brought against any indemnified party and it shall notify an indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it may desire, jointly with any other indemnifying party similarly notified, to assume the defense thereof through counsel reasonably satisfactory to the indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 10.04 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof, other than reasonable costs of investigation (unless (i) such indemnified party reasonably objects to such assumption on the grounds that there may be defenses available to it which are different from or in addition to those available to such indemnifying party, (ii) the indemnifying party and such indemnified party shall have mutually agreed to the retention of such counsel or (iii) in the reasonable opinion

of such indemnified party representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding, in which case the indemnified party shall be reimbursed by the indemnifying party for the reasonable expenses incurred in connection with retaining one firm of separate legal counsel; provided that (i) in circumstances where Ashland or an underwriter or initial purchaser is the indemnifying party, the indemnifying party shall not be liable for more than one firm of legal counsel for all indemnified parties and (ii) in circumstances where the Issuer is the indemnifying party, the indemnifying party shall not be liable for more than (A) one firm of legal counsel for Ashland, each person who controls Ashland within the meaning of Section 15 of the Securities Act, and any director, officer, employee, stockholder, partner, agent or representative of Ashland, and (B) one firm of legal counsel for the underwriters or initial purchasers, if any, indemnified under this Section 10.04, each person who controls such underwriters or initial purchasers within the meaning of Section 15 of the Securities Act, and any director, officer, employee, stockholder, partner, agent or representative of such underwriters or initial purchasers). No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any claim or pending or threatened proceeding in respect of which the indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability arising out of such claim or proceeding. If an indemnifying party shall have expressly acknowledged its indemnification obligations with respect to a claim or pending or threatened proceeding, then the indemnified party with respect to such claim or pending or threatened proceeding shall not, without the prior written consent of the indemnifying party, effect any settlement of such claim or pending or threatened proceeding.

If the indemnification provided for in this Section 10.04 is unavailable to an indemnified party or is insufficient to hold such indemnified party harmless from any Losses in respect of which this Section 10.04 would otherwise apply by its terms (other than by reason of exceptions provide herein), then each applicable

indemnifying party, in lieu of indemnifying such indemnified party, shall have a joint and several obligation to contribute to the amount paid or payable by such indemnified party as a result of such Losses, in such proportion as is appropriate to reflect the relative benefits received by and fault of the indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the offering or private placement to which such contribution relates as well as any other relevant equitable considerations. The relative benefit shall be determined by reference to, among other things, the amount of proceeds received by each party from the offering or private placement to which such contribution relates. The relative fault shall be determined by reference to, among other things, each party’s relative knowledge and access to information concerning the matter with respect to which the claim was asserted, and the opportunity to correct and prevent any statement or omission. The amount paid or payable by a party as a result of any Losses shall be deemed to include any legal or other fees or expenses incurred by such party in connection with any investigation or proceeding, to the extent such party would have been indemnified for such expenses if the indemnification provided for in this Section 10.04 was available to such party.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 10.04 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the immediately preceding paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

SECTION 10.05. Underwriting Agreement; Purchase Agreement. In connection with any underwritten offering or private placement of Securities pursuant to a Demand Registration under Section 10.01, the Issuer and Ashland shall enter into an underwriting agreement with the underwriters for such offering or a purchase agreement with the initial purchasers for such private placement, such underwriting agreement or purchase agreement to contain such representations and warranties by the Issuer and Ashland and such other terms and provisions as are customarily contained

in underwriting agreements with respect to secondary distributions or purchase agreements with respect to private placements, including, without limitation, indemnities and contribution to the effect and to the extent provided in Section 10.04 (and customary provisions with respect to indemnities and contribution by such underwriters or initial purchasers).

SECTION 10.06. Undertaking To File Reports. For as long as Ashland holds Securities, the Issuer shall use its best efforts to file, on a timely basis, all annual, quarterly and other reports required to be filed by it under Sections 13 and 15(d) of the Exchange Act and the rules and regulations of the Commission thereunder, as amended from time to time, or any successor statute or provisions.

SECTION 14.01. Competitive Businesses. (a) Subject to Sections 14.01(b), 14.01(d) and 14.03(c), and except to the extent otherwise provided in Schedule 14.01(a), each of Marathon, USX and Ashland hereby agrees that during the Term of the Company, it shall not, and it shall cause its Affiliates not to, engage in any business within North America which is substantially in competition with (i) the Company’s Business conducted on the date hereof or (ii) any new line of business of the Company that the Board of Managers has approved in accordance with Section 8.07(b) of the LLC Agreement (but only if and to the extent that the Board of Managers specifically determined pursuant to Section 8.07(b) of the LLC Agreement that such new line of business should also constitute a Company Competitive Business) (each such business in clauses (i) and (ii), a “Company Competitive Business”); provided, however, that nothing in this Section 14.01 shall be deemed or interpreted to prohibit Ashland or any of its Affiliates from engaging in the Valvoline Business.

(b) Notwithstanding any limitation contained in Section 14.01(a), Marathon, USX and Ashland and their respective Affiliates shall be permitted to engage in a Company Competitive Business if: (i) Marathon or Ashland, as applicable, shall have first presented the Company, at a meeting of the Board of Managers at which at least one of the Representatives of the other Member was present, with the opportunity to pursue or engage in such Company Competitive Business and (ii) one or more of the Representatives of the other Member on the Board of Managers shall have voted against the Company pursuing such Company Competitive Business.

(c) If Marathon, USX or Ashland or any of their respective Affiliates is permitted pursuant to Section 14.01(b) to engage in a Company Competitive Business and, in connection therewith, wishes to use any of the properties, facilities or other assets of the Company or any of its subsidiaries, Marathon or Ashland and their respective Representatives will negotiate in good faith with the Company to reach a reasonable agreement as to the nature and scope of any agreement between the Company or any such subsidiary and such Member with respect to the use of such property, facility or other assets. Any transaction relating to such property, facility or assets shall be deemed for purposes of the LLC Agreement to constitute an Affiliate Transaction that was entered into outside the ordinary course of the Company’s business.

(d) Notwithstanding any limitation contained in Section 14.01(a), Marathon, USX and Ashland and their respective Affiliates shall be permitted to purchase: (i) less than an aggregate of 10% of any class of stock of a person engaged, directly or indirectly, in one or more Competitive Businesses (a “Company Competitive Third Party”); provided that such stock is listed on a national securities exchange or is quoted on the National Market System of NASDAQ; (ii) less than 10% in value of any instrument of Indebtedness of a Company Competitive Third Party; (iii) a Company Competitive Third Party (whether by merger or purchase of all or substantially all of such Company Competitive Third Party’s assets) which engages, directly or indirectly, in one or more Company Competitive Businesses which accounted for less than 20% of such Company Competitive Third Party’s consolidated revenues for the most recently completed fiscal quarter; and (iv) a Company Competitive Third Party (whether by merger or purchase of

all or substantially all of such Company Competitive Third Party’s assets or otherwise) which engages, directly or indirectly, in one or more Company Competitive Businesses which accounted for greater than 20% of such Company Competitive Third Party’s consolidated revenues for the most recently completed fiscal quarter; provided that a purchase by Marathon, USX or Ashland or any of their respective Affiliates of a Company Competitive Third Party pursuant to this clause (iv) shall only be permitted if within 30 Business Days after the earlier to occur of (A) the execution of definitive agreements with respect to such purchase or (B) the closing of such purchase, Marathon, USX, Ashland or such Affiliate, as applicable, shall present the Company with the opportunity to purchase the portion of such Company Competitive Third Party’s business that is in substantial competition with the Company in North America (the “Company Competitive Business Assets”) at a purchase price determined in accordance with Section 14.04, at a special or regular meeting of the Board of Managers (such meeting, a “14.01(d) Presentation Meeting”).

(e) If the Board of Managers determines at the 14.01(d) Presentation Meeting (by a vote of a majority of the Representatives of the Member not purchasing such Company Competitive Third Party’s business at a special or regular meeting of the Board of Managers (which majority shall constitute a quorum for purposes of the transaction of business)) to purchase the Company Competitive Business Assets, the closing date with respect to such purchase shall not be later than 60 days after the date of the determination of the Purchase Price pursuant to Section 14.04 or, if later, 30 days after the Company has received any antitrust clearance or other Governmental Approval required in connection with such purchase (the “14.01(d) Scheduled Closing Date”). If the Company breaches its obligation to purchase the Company Competitive Business Assets on the 14.01(d) Scheduled Closing Date after the Board of Managers shall have determined to make such purchase as provided in the immediately preceding sentence (other than where such breach is due to circumstances beyond the Company’s reasonable control), then Marathon, USX, Ashland or such Affiliate, as applicable, shall be permitted to retain such Company Competitive Business Assets and the Company shall cease to have the right to purchase such Company Competitive Business Assets. If the Company breaches its obligation to purchase the Company Competitive Business Assets on the 14.01(d) Scheduled Closing Date after

the Board of Managers shall have determined to make such purchase as provided in the first sentence of this Section 14.01(e)and such breach is due to circumstances beyond the Company’s reasonable control, then, if the closing of the purchase by the Company of the Company Competitive Business Assets does not occur within 270 days after the Scheduled Closing Date, Marathon, USX, Ashland or such Affiliate, as applicable, shall be permitted to retain such Company Competitive Business Assets and the Company shall cease to have the right to purchase such Company Competitive Business Assets. If the Board of Managers determines at the 14.01(d) Presentation Meeting not to purchase such Company Competitive Business Assets, then Marathon, USX, Ashland or such Affiliate, as applicable, shall be permitted to retain such Company Competitive Business Assets and the Company shall cease to have the right to purchase such Company Competitive Business Assets.

(f) It is the intention of each of the parties hereto that if any of the restrictions or covenants contained in this Section 14.01 is held by a court of competent jurisdiction to cover a geographic area or to be for a length of time that is not permitted by Applicable Law, or is in any way construed by a court of competent jurisdiction to be too broad or to any extent invalid, such provision shall not be construed to be null, void and of no effect, but to the extent such provision would be valid or enforceable under Applicable Law, a court of competent jurisdiction shall construe and interpret or reform this Section 14.01 to provide for a covenant having the maximum enforceable geographic area, time period and other provisions (not greater than those contained in this Section 14.01) as shall be valid and enforceable under such Applicable Law. Each of the parties hereto acknowledges that any breach of the terms, conditions or covenants set forth in this Section 14.01 shall be competitively unfair and may cause irreparable damage to the Company because of the special, unique, unusual, extraordinary and intellectual character of the Company’s business, and the Company’s recovery of damages at law will not be an adequate remedy. Accordingly, each of the parties hereto agrees that for any breach of the terms, covenants or agreements of this Section 14.01, a restraining order or an injunction or both may be issued against such person, in addition to any other rights or remedies the Company or the other parties hereto may have.

SECTION 14.02. Detrimental Activities. (a) Solicitation, Recruiting or Hiring of Employees. Each of Marathon, USX and Ashland hereby agrees that during the Term of the Company, without the consent of each of the Members, it shall not, and it shall cause its Affiliates not to, solicit, recruit or hire any employee of the Company or any of its subsidiaries (other than solicitations that are directed at the public in general in publications available to the public in general) if:

(i) such employee is an Executive Officer or the officer principally in charge of environmental health and safety and human resources, unless, subject to clauses (iii) and (iv) below, such solicitation, recruitment or hiring is consented to in advance by Ashland (in the case of a solicitation, recruitment or hiring by Marathon, USX or any of their respective Affiliates) or by Marathon (in the case of a solicitation, recruitment or hiring by Ashland or any of its Affiliates), which consent shall not be unreasonably withheld;

(ii) such employee reports directly to (A) an Executive Officer or the officer principally in charge of environmental health and safety and human resources(a “Senior Employee”) or (B) a Senior Employee (a “Mid-Level Employee”), unless, subject to clauses (iii) and (iv) below, at the time of such solicitation, recruitment or hiring, the total number of Senior Employees and Mid-Level Employees that have been hired by Marathon, USX, Ashland and their respective Affiliates during the then preceding twenty- four months is less than 10% of the total number of Senior Employees and Mid-Level Employees employed by the Company at the time Marathon, USX, Ashland or an Affiliate thereof wishes to solicit, recruit or hire such Senior Employee or Mid-Level Employee (based on the average number of Senior Employees and Mid-Level Employees employed by the Company during such twenty-four-month period);

(iii) the hiring of such employee, when considered together with all other employees hired by Marathon, USX, Ashland and their respective Affiliates during the then preceding twenty-four months, would have or would reasonably be expected to have, a significant

detrimental impact on the department of the Company in which such employee is then working; or

(iv) such employee is being solicited, recruited or hired for a position in a Competitive Business of such person or such person’s Affiliates.

Notwithstanding the foregoing, the employees of the Company shall not be required to accept any job offer by Marathon, USX, Ashland or any of their respective Affiliates and a refusal to accept such a job offer shall not negatively affect an employee’s career opportunities at the Company.

(b) Disclosure of Confidential Information. Each of Marathon, USX and Ashland (each, a “Disclosing Party”) hereby agrees that during the Term of the Company, it shall not, and it shall cause its Affiliates not to, disclose or furnish to anyone any confidential information relating to the Company and its subsidiaries (“Confidential Information”) except pursuant to a confidentiality agreement in form and substance reasonably satisfactory to the other parties hereto which expressly provides that the other parties hereto shall be a beneficiary thereof (a “Confidentiality Agreement”). The foregoing restriction on disclosure of Confidential Information shall not apply to (i) information which is or becomes part of the public domain through no fault or breach of the Disclosing Party; (ii) information which at the time of disclosure is already in the possession of the Disclosing Party in written form and was not received directly or indirectly from the Company or any of its subsidiaries under a requirement of confidentiality; (iii) information received by the Disclosing Party from a third party; provided that the Disclosing Party, after reasonable inquiry, has no reason to believe that the third party obtained the information directly or indirectly from the Company or any of its subsidiaries under a requirement of confidentiality; (iv) information required to be disclosed under subpoena or other mandatory legal process; provided, that the Disclosing Party shall give the Company timely notice of the service of the subpoena or other process so that the Company may seek a protective order or other legal remedy to prevent such disclosure; (v) information which has been subsequently and independently acquired or developed by the Disclosing Party without violating any of its obligations under this Section 14.02(b) or under any Confidentiality Agreement; and (vi) information which is required or advisable to be disclosed

under the Securities Act or the Exchange Act. Notwithstanding the foregoing, a Disclosing Party shall be permitted to disclose Confidential Information to its directors, officers, employees, auditors, agents, advisors and representatives (such persons being collectively referred as its “Representatives”) if the Disclosing Party informs its Representatives of the confidential nature of the Confidential Information and obtains their agreement to be bound by this Section 14.02(b) and not to disclose such Confidential Information to any other person. Each Disclosing Party shall be responsible for any breach of this Section 14.02 by its Representatives.

SECTION 14.03. Limitations on the Company Entering into the Valvoline Business. (a) Subject to Sections 14.03(b) and 14.03(d), the Company hereby agrees that it shall not, and it shall cause its Affiliates (other than Marathon, Ashland and their respective subsidiaries (other than the Company and its subsidiaries)) not to, engage in any business worldwide which is substantially in competition with the Valvoline Business. Notwithstanding the foregoing, the provisions of this Section 14.03(a) shall terminate on the first date on which Ashland and its Affiliates shall own (beneficially or otherwise) less than 20% of the Valvoline Business.

(b)(i) Notwithstanding any limitation contained in Section 14.03(a), if in any two consecutive calendar years, (A) Valvoline shall not have purchased from the Company and its subsidiaries a quantity of lube oil at least equal to the Minimum Lube Oil Purchase Amount and (B)(1) such failure to purchase was due to the fact that the Company and Valvoline could not in good faith agree to mutually acceptable terms and conditions for the sale by the Company and its subsidiaries to Valvoline of at least such quantity of lube oil and (2) such failure was not due, in whole or in part, to the failure of the Company and its subsidiaries to produce and offer for sale to Valvoline the Minimum Lube Oil Purchase Amount during either such calendar year, the failure of the Company and its subsidiaries to produce and offer for sale to Valvoline lube oil satisfying contractual specifications or any other failure of the Company or its subsidiaries to satisfy in any material respect any of its then existing material contractual obligations to Valvoline, then the Company and its subsidiaries shall be permitted to

engage in a business which is substantially in competition with Valvoline’s Bulk Motor Oil Business and/or Valvoline’s Packaged Motor Oil Business (but, except as expressly permitted in Section 14.03(a), no other business that constitutes part of the Valvoline Business); provided that, notwithstanding the foregoing, the Company and its subsidiaries shall not be permitted to enter into or engage in any such business if the Company and its subsidiaries shall have substantially ceased production at the Catlettsburg, Kentucky refinery of lube oil for sale to third parties (other than due to a force majeure or an inability to find a willing buyer for its lube oil) for any period of 90 consecutive days or more prior to the time the Company and its subsidiaries shall first enter or propose to enter into such business.

(ii) Notwithstanding any limitation contained in Section 14.03(a), if in each of the four calendar years following the consecutive two-year period provided for in Section 14.03(b)(i), (A) Valvoline shall not have purchased from the Company and its subsidiaries a quantity of lube oil at least equal to the Minimum Lube Oil Purchase Amount and (B)(1) such failure to purchase was due to the fact that the Company and Valvoline could not in good faith agree to mutually acceptable terms and conditions for the sale by the Company and its subsidiaries to Valvoline of at least such quantity of lube oil and (2) such failure was not due, in whole or in part, to the failure of the Company and its subsidiaries to produce and offer for sale to Valvoline the Minimum Lube Oil Purchase Amount during any such calendar year, the failure of the Company and its subsidiaries to produce and offer for sale to Valvoline lube oil satisfying contractual specifications or any other failure of the Company or its subsidiaries to satisfy in any material respect any of its existing material contractual obligations to Valvoline, then at any time after the conclusion of such consecutive four-year period, the Company and its subsidiaries shall be permitted to engage in a business which is substantially in competition with Valvoline’s Private Label Packaged Motor Oil Business and/or Valvoline’s Quick Lube Business; provided that, notwithstanding the foregoing, the Company and its subsidiaries shall not be permitted to enter into or engage in any such business if the Company and its subsidiaries shall have

substantially ceased production at the Catlettsburg, Kentucky refinery of lube oil for sale to third parties (other than due to a force majeure or an inability to find a willing buyer for its lube oil) for any period of 90 consecutive days or more prior to the time the Company and its subsidiaries shall first enter or propose to enter into such business.

(iii) The provisions set forth in this Section 14.03(b) permitting the Company and its subsidiaries to engage in a new business in competition with the Valvoline Business if certain conditions are satisfied shall be an exception only to the super majority vote requirement in Section 8.08(a) of the LLC Agreement, and shall not be an exception to any other supermajority vote requirements of Section 8.08 of the LLC Agreement.

(c) Notwithstanding any limitation contained in Section 14.01(a), if at any time the Company or any of its subsidiaries enters into, other than as expressly permitted in Section 14.03(d), either the Bulk Motor Oil Business, the Packaged Motor Oil Business, the Private Label Packaged Motor Oil Business or the Quick Lube Business, Ashland and its subsidiaries thereafter shall be permitted to enter into a business which is substantially in competition with the Company’s lube oil production business.

(d) Notwithstanding any limitation contained in Section 14.03(a), subject to Section 8.08 of the LLC Agreement, the Company and its subsidiaries shall be permitted to (i) engage, directly or through its own dealers, jobbers or jobber dealers, in the business currently conducted under the brand name “Maralube Express” (the “Maralube Express Business”); (ii) engage, directly or through its own dealers, jobbers or jobber dealers, in the truck stop oil change business; (iii) engage, directly or through its own dealers, jobbers, or jobber dealers, in the oil, lubricants, antifreeze and other, in each case automotive fluid change business and auto and light truck maintenance service, in each case incidental to operating their service stations or other retail units; (iv) engage, directly or through its own dealers, jobbers, or jobber dealers, in the sale of lubricants to farm, government, school and other similar commercial accounts; (v) engage, directly or through its own dealers, jobbers, or jobber dealers, in the sale of car care products and chemicals,

(e) Ashland shall have 90 days from receipt of the 14.03(d) Offer Notice to elect, by notice to the Company (a “14.3(d) Purchase Election Notice”), to purchase such Valvoline Competitive Business Assets. If Ashland makes such election, the notice of election shall state a closing date not later than 60 days after the date of the Section 14.03(d) Purchase Election Notice or, if later, 30 days after Ashland has received any antitrust clearance or other

Governmental Approval required in connection with such purchase (a “14.03(d) Scheduled Closing Date”). If Ashland breaches its obligation to purchase the Valvoline Competitive Business Assets on the 14.03(d) Scheduled Closing Date after giving notice of its election to make such purchase (other than where such breach is due to circumstances beyond Ashland’s reasonable control), then the Company shall be permitted to retain such Valvoline Competitive Business Assets. If Ashland breaches its obligation to purchase the Valvoline Competitive Business Assets on the 14.03(d) Scheduled Closing Date after giving notice of its election to make such purchase and such breach is due to circumstances beyond Ashland’s reasonable control, then, if the closing of the purchase by Ashland of the Valvoline Competitive Business Assets does not occur within 270 days after the Scheduled Closing Date, the Company shall be permitted to retain such Valvoline Competitive Business Assets. If Ashland elects not to purchase such Valvoline Competitive Business Assets, then the Company shall be permitted to retain such Valvoline Competitive Business Assets.

(f) (i) If the Company and its subsidiaries are permitted under Section 14.03(d) to retain any Valvoline Competitive Business Assets and, at any time thereafter, the Company or any such subsidiary shall determine to sell such Valvoline Competitive Business Assets (or any portion thereof), then the Company shall give notice (a “14.03(f) Valvoline Offer Notice”) to Ashland, identifying the proposed purchaser from whom it has received a bona fide offer and setting forth the proposed sale price (which shall be payable only in cash or purchase money obligations secured solely by such Valvoline Competitive Business Assets (or portion thereof) being sold) and the other material terms and conditions upon which the Company is proposing to sell such Valvoline Competitive Business Assets to such identified purchaser (or portion thereof). No such sale shall encompass or be conditioned upon the sale or purchase of any property other than such Valvoline Competitive Business Assets (or portion thereof). Ashland shall have 90 days from receipt of the Valvoline Offer Notice to elect, by notice to the Company (a “14.03(f) Valvoline Purchase Election Notice”), to purchase such Valvoline Competitive Business Assets (or portion thereof) on the terms and conditions set forth in the 14.03(f) Valvoline Offer Notice.

(ii) If Ashland makes such election, the notice of election shall state a closing date not later than 60 days after the date of the 14.03(f) Valvoline Purchase Election Notice. If Ashland breaches its obligation to purchase such Valvoline Competitive Business Assets (or portion thereof) on the same terms and conditions as those contained in the 14.03(f) Valvoline Offer Notice after giving notice of its election to make such purchase (other than where such breach is due to circumstances beyond Ashland’s reasonable control), then the Company may, at any time for a period of 270 days after such default, sell such Valvoline Competitive Business Assets (or portion thereof) to any person at any price and upon any other terms without further compliance with the procedures set forth in this Section 14.03(f).

(iii) If Ashland gives notice within the 90-day period following the 14.03(f) Valvoline Offer Notice from the Company that it elects not to purchase such Valvoline Competitive Business Assets (or portion thereof), the Company may, within 120 days after the end of such 90-day period (or 270 days in the case where such parties have received a second request under HSR), sell such Valvoline Competitive Business Assets to the identified purchaser on terms and conditions no less favorable to the Company than the terms and conditions set forth in such 14.03(f) Valvoline Offer Notice. In the event the Company shall desire to offer such Valvoline Competitive Business Assets (or portion thereof) for sale to such identified purchaser or to any other person on terms and conditions less favorable to it than those previously set forth in a 14.03(f) Valvoline Offer Notice, the procedures set forth in this Section 14.03(f) must again be initiated and applied with respect to the terms and conditions as modified.

(g) It is the intention of each of the parties hereto that if any of the restrictions or covenants contained in this Section 14.03 is held by a court of competent jurisdiction to cover a geographic area or to be for a length of time that is not permitted by Applicable Law, or is in any way construed by a court of competent jurisdiction to be too broad or to any extent invalid, such provision shall not be construed to be null, void and of no effect, but to the extent such provision would be valid or enforceable under Applicable Law, a court of competent jurisdiction shall construe and interpret or reform this Section 14.03 to provide for a covenant having the maximum enforceable geographic area, time period and other

provisions (not greater than those contained in this Section 14.03) as shall be valid and enforceable under such Applicable Law. Each of the parties hereto acknowledges that any breach of the terms, conditions or covenants set forth in this Section 14.03 shall be competitively unfair and may cause irreparable damage because of the special, unique, unusual, extraordinary and intellectual character of the applicable business, and recovery of damages at law will not be an adequate remedy. Accordingly, each of the parties hereto agrees that for any breach of the terms, covenants or agreements of this Section 14.03, a restraining order or an injunction or both may be issued against such person, in addition to any other rights or remedies the aggrieved party may have.

(h) For purposes of this Agreement, the following terms shall have the following meanings:

(i) “Bulk Motor Oil Business” means sales of blended (finished) motor oil in tanker truck, barge and tanker railcar quantities.

(ii) “Minimum Lube Oil Purchase Amount” means a quantity of lube oil at least equal to 70% of the quantity of lube oil that Valvoline purchased from the Catlettsburg, Kentucky refinery in the 1997 calendar year.

(iii) “Packaged Motor Oil Business” means the ownership, use and/or operation (including toll processing through a third party’s plant) of packaging facilities for the sale of packaged motor oil under third party brandnames or trademarks.

(v) “Quick Lube Business” means the provision of services for changing oil, lubricants, antifreeze and other automotive fluids for passenger car and light commercial trucks and the provision of maintenance checks and related services.

(vii) “Valvoline Business” means the business currently engaged in by Valvoline, including (A) the production and marketing of automotive and industrial oils, automotive car care products and chemicals, antifreeze, rust preventives, (B) automotive services and (C) environmental recycling services (including collection of used oil, filters and related items). For the avoidance of doubt, the Valvoline Business includes the Bulk Motor Oil Business, the Packaged Motor Oil Business, the Private Label Packaged Motor Oil Business and the Quick Lube Business.

SECTION 14.04. Purchase Price of Competitive Business Assets. In the event that (x) the Company elects to purchase any Company Competitive Business Assets pursuant to the proviso to Section 14.01(d)(iv) or (y) Ashland elects to purchase any Valvoline Competitive Business Assets pursuant to the second proviso to Section 14.03(d)(viii), the purchase price of such Company Competitive Business Assets or Valvoline Competitive Business Assets (the “Competitive Business Purchase Price”) shall be determined pursuant to the following procedures:

(a) Negotiation Period. For a period of 15 days following the date the Board of Managers approves such purchase, Marathon and Ashland will negotiate in good faith to seek to reach an agreement as to the Competitive Business Purchase Price. If Marathon and Ashland reach such an agreement, then the Competitive Business Purchase Price shall be deemed to be the amount so agreed upon by Marathon and Ashland.

(b) Appraisal Process. (i) In the event Marathon and Ashland are unable to reach an agreement as to the Competitive Business Purchase Price within the 15 day period referred to in clause (a) above, then within five Business Days after the expiration of such 15-day period (such fifth Business Day being referred to herein as the “14.04 Appraisal Process Commencement Date”), Marathon and Ashland each shall select a nationally recognized investment banking firm to (A) prepare a report which (1) sets forth such investment banking firm’s determination of the Competitive Business Purchase Price (which shall be a single amount as opposed to a range) and (2) includes work papers which indicate the basis for the calculations of the Competitive Business Purchase Price

(a “14.04 Appraisal Report”) and (B) deliver to Marathon or Ashland, as the case may be, an oral and written opinion addressed to such party as to the Competitive Business Purchase Price.

(ii) The fees and expenses of each investment banking firm shall be paid by the party selecting such investment banking firm.

(iii) Each of Marathon and Ashland shall instruct its respective investment banking firm to (A) not consult with the other investment banking firm with respect to its view as to the Competitive Business Purchase Price prior to the time that both investment banking firms have delivered their respective opinions to Marathon and Ashland, as applicable, (B) deliver their respective 14.04 Appraisal Reports, together with their oral and written opinions as to the Competitive Business Purchase Price (the “14.04 Initial Opinion Values”), within 15 days after the 14.04 Appraisal Process Commencement Date, and (C) deliver a copy of its written opinion and its 14.04 Appraisal Report to the Company, the other party and the other party’s investment banking firm at the time it delivers its oral and written opinion to Marathon or Ashland, as applicable.

(iv) If the 14.04 Initial Opinion Values differ and the lesser 14.04 Initial Opinion Value equals or exceeds 90% of the greater 14.04 Initial Opinion Value, the Competitive Business Purchase Price shall be deemed to be an amount equal to (A) the sum of the 14.04 Initial Opinion Values divided by (B) two.

(v) If the 14.04 Initial Opinion Values differ and the lesser 14.04 Initial Opinion Value is less than 90% of the greater 14.04 Initial Opinion Value then:

(A) within two Business Days after both investment banking firms have delivered their respective opinions to Marathon or Ashland, as applicable, each investment banking firm shall, at a single meeting at which Marathon, Ashland, the Company and the other investment banking firm are present, make a presentation with respect to its 14.04 Initial Opinion Value. At such presentation, Marathon, Ashland, the Company and the other

investment banking firm shall be entitled to ask questions as to the basis for and the calculation of such investment banking firm’s 14.04 Initial Opinion Value; and

(B) Marathon and Ashland shall, within five Business Days after the date Marathon and Ashland receive the 14.04 Initial Opinion Values (such fifth Business Day being referred to herein as the “14.04 Subsequent Appraisal Process Commencement Date”), jointly select a third nationally recognized investment banking firm to (1) prepare a 14.04 Appraisal Report and (2) deliver an oral and written opinion addressed to Marathon and Ashland as to the Competitive Business Purchase Price. The fees and expenses of such third investment banking firm shall be paid 50% by Marathon and 50% by Ashland. Such third investment banking firm shall not be provided with the 14.04 Initial Opinion Values and shall not consult with the initial investment banking firms with respect thereto. During such five- Business Day period, Marathon and Ashland shall negotiate in good faith to independently reach an agreement as to the Competitive Business Purchase Price. If Marathon and Ashland reach such an agreement, then the Competitive Business Purchase Price shall be deemed to be the amount so agreed upon by Marathon and Ashland. If Marathon and Ashland are unable to reach such an agreement, then Marathon and Ashland shall instruct such third investment banking firm to deliver its 14.04 Appraisal Report, together with its oral and written opinion as to the Competitive Business Purchase Price (the “14.04 Third Opinion Value”), within 15 days after the 14.04 Subsequent Appraisal Process Commencement Date. The Competitive Business Purchase Price in such circumstances shall be deemed to be an amount equal to (I) the sum of (x) the 14.04 Third Opinion Value plus (y) which ever of the two 14.04 Initial Opinion Values is closer to the 14.04 Third Opinion Value (or, if the 14.04 Third Opinion Value is exactly halfway between the two 14.04 Initial Opinion Values, the 14.04 Third Opinion Value), divided by (II) two.

SECTION 15.01. Survival and Assignment re: Marathon and USX. (a) General.
