For the purposes of this Formation Agreement, the Capex Adjustment means the positive amount, if any, equal to (A) minus (B); where (A) shall be equal to the aggregate amount set forth on Section 2.6 of the Disclosure Schedules with respect to the period from and after January 1, 2010 and prior to the Effective Time and where (B) shall be equal to the actual amount incurred and paid by MPC and its Affiliates from and after January 1, 2010 and prior to the Effective Time with respect to capital expenditures related to the Businesses during such period. For the avoidance of doubt, the Capex Adjustment shall not be less than zero.

(b) MPC shall cause to be prepared and delivered to NTI a written statement within thirty (30) days following the Closing Date setting forth the amount of the Capex Adjustment, together with supporting calculations and information (the “Capex Adjustment Statement”) which notice shall be prepared in accordance with the definitions and provisions of this Formation Agreement.

Execution Copy

(c) On or prior to the thirtieth (30^th) Business Day following receipt by NTI of the Capex Adjustment Statement (the “Capex Objection Period”), NTI shall deliver to MPC either a Notice of Acceptance or a Notice of Disagreement. If NTI delivers to MPC a Notice of Acceptance, or NTI does not deliver a Notice of Disagreement on or prior to the last day of the Capex Objection Period, then effective as of the earlier of the date of delivery of such Notice of Acceptance or the last day of the Capex Objection Period, the Capex Adjustment Statement and the determination contained therein shall be final, binding and conclusive upon the Parties. If NTI timely delivers a Notice of Disagreement with respect to the Capex Adjustment Statement, only those matters specified in such Notice of Disagreement shall be deemed to be in dispute, and all other matters included in the Capex Adjustment Statement shall be final, binding and conclusive upon the Parties and not subject to any further challenge on any ground for any purpose, except for instances of fraud and/or manifest error.

Any distribution or contribution required hereunder shall be made on or before the fifteenth (15^th) Business Day after the final determination of the Capex Adjustment Statement in accordance with Section 2.6(c).

Section 2.7 Accounts Payable.

(a) At the Closing, NTE will create an accounts payable to MPC (the “Accounts Payable”) in an amount jointly determined by NTI and MPC (the “Accounts Payable Amount”). The guiding principles for determining the value of the Accounts Payable Amount shall be that if the total of the estimated values listed in (i) through (v) immediately below is $265 million, then the Accounts Payable Amount will be $106 million. If the total of such estimated values is more or less than $265 million, the Accounts Payable Amount will be increased or decreased, as applicable, by the amount of such difference and it being understood that MPC will receive cash payments at Closing attributable to inventory equal to the lesser of (x) $165,000,000 and (y) the total of the estimated values listed in (i) through (v) immediately below. In all cases the Accounts Payable Amount will be rounded to the nearest $1 million. In no event will the Accounts Payable Amount be greater than the sum of:

(i) the Estimated Refinery Inventory Price; plus

(ii) the Estimated Undelivered Refinery Inventory Price; plus

(iii) the Estimated Marketing Fuel Inventory; plus

(iv) the Estimated Merchandise Price; plus

Execution Copy

(v) the Estimated SuperMom’s Inventory Price; plus

(vi) $6,000,000, in respect of NTE’s allocated cost of the September 2010 Planned Unit Turnaround.

(b) The Accounts Payable will provide for the payment by NTE, or by the bank issuing the Letter of Credit, to MPC of the Accounts Payable Amount in equal installments commencing on the twelfth (12^th) day following the Closing and continuing each day through the ninetieth (90^th) day following the Closing. For each day on which a payment is due, but which is not a Business Day, the payment for that day will be made, along with the regularly scheduled payment, on the next Business Day.

(c) The first $106 million of the Accounts Payable Amount will be secured by a pledge of the Common Interests pursuant to a pledge and security agreement substantially in the form of Exhibit F to this Formation Agreement (the “Pledge Agreement”). If the Accounts Payable Amount is in excess of $106 million, the amount thereof in excess of $106 million will be secured by a commercial letter of credit (documentary) from a bank and in a form reasonably satisfactory to MPC (the “Letter of Credit”). The Pledge Agreement will remain in effect until the next Business Day following the first anniversary of the last payment made to MPC of the Accounts Payable Amount. The Letter of Credit will remain outstanding until the last payment by the bank pursuant to such Letter of Credit.

(d) Each of the applicable lenders to NT Holdco or its Subsidiaries will execute an authorization for the Accounts Payable and a release of any claim to the Common Interests secured by the Pledge Agreement in a form reasonably satisfactory to MPC (the “Release Agreement”).

Section 2.8 Margin Support.

(a) Within 90 days following (i) the last day of the twelve-month period commencing on the Closing Date (the “First Margin Support Period”) and (ii) the last day of twelve-month period commencing on the day after the First Margin Support Period (such period, the “Second Margin Support Period” and, together with the First Margin Support Period, the Margin Support Periods or a Margin Support Period), NTE shall deliver a written statement to MPC which shall set forth (i) the amount of EBITDA earned during such Margin Support Period and (ii) the Margin Support Payment (as defined in Section 2.8(d) below), if any, for such Margin Support Period (such statement, the “Margin Support Statement”). NTE shall include with the Margin Support Statement supporting documentation, which shall include a balance sheet, a statement of operations and a statement of cash flows, in each case as at the end of and for such Margin Support Period, prepared in accordance with GAAP.

(b) On or prior to the 30th Business Day following receipt by MPC of a Margin Support Statement (with respect to each Margin Support Period, the “Margin Support Objection Period”), MPC shall deliver to NTE either a notice indicating that MPC accepts such Margin Support Statement (a “Margin Support Acceptance Notice”) or a written statement

Execution Copy

specifying those items or amounts with which MPC disagrees in such Margin Support Statement (a “Margin Support Disagreement Notice”). During such Margin Support Objection Period, MPC shall have reasonable access upon reasonable notice to the applicable books, records and staff of NTE and its Subsidiaries for the purposes of verifying the Margin Support Statement. If MPC delivers to NTE a Margin Support Acceptance Notice, or if MPC does not deliver a Margin Support Disagreement Notice on or prior to the last day of a Margin Support Objection Period, then such Margin Support Statement shall be deemed to be a Final Margin Support Statement and the determination therein shall be final, binding and conclusive upon MPC and NTE. If MPC timely delivers a Margin Support Disagreement Notice with respect to a Margin Support Statement, only those matters specified in such Margin Support Disagreement Notice shall be deemed to be in dispute, and all other matters included in such Margin Support Statement shall be final, binding and conclusive upon MPC and NTE and not subject to further challenge on any ground for any purpose, except for instances of fraud or manifest error. The objections set forth in a Margin Support Disagreement Notice shall be resolved as follows:

(i) MPC and NTE shall consult in good faith and use commercially reasonable efforts to resolve such objections. Any such resolution shall be reduced to a written agreement executed by MPC and NTE and such written agreement shall be final, binding and conclusive upon the Parties, and not subject to any further challenge on any ground for any purpose, except for instances of fraud and/or manifest error.

(ii) If MPC and NTE do not resolve by written agreement all of the objections set forth on a Margin Support Disagreement Notice within 30 Business Days after delivery of such Margin Support Disagreement Notice, MPC and NTE shall submit the dispute to the Accounting Arbitrator for final resolution, which resolution shall be final, binding and conclusive upon the Parties, and not subject to any further challenge on any ground for any purpose, except for instances of fraud and/or manifest error. The fees and expenses of such accounting firm for its services in resolving such dispute shall be borne equally by MPC and NTE.

(c) A Margin Support Statement with respect to a Margin Support Period shall become a Final Margin Support Statement on the earliest to occur of: (i) the expiration of the Margin Support Objection Period for such Margin Support Period if a Margin Support Disagreement Notice has not been timely delivered to NTE, (ii) the date that a Margin Support Acceptance Notice with respect to such Margin Support Period has been delivered to NTE, (iii) the date the agreement contemplated by Section 2.8(b)(i) is executed (with such Margin Support Statement being adjusted to reflect matters resolved pursuant to such written agreement), or (iv) the date the Accounting Arbitrator delivers its final determination of the Margin Support Payment pursuant to Section 2.8(b)(ii). The date on which a Margin Support Statement becomes a Final Margin Support Statement pursuant to the immediately foregoing sentence is referred to as a “Margin Support Final Determination Date”).

(d) If, for a Margin Support Period, the EBITDA is less than $145 million, then MPC will pay to NTE an amount equal to the difference between the EBITDA for such

Execution Copy

Margin Support Period and $145 million (the “Margin Support Payment”); provided, however, that the amount of such payment by MPC will not exceed $30 million for either 12-month period. Each payment, if any, will be made by MPC to NTE within five (5) Business Days of the Margin Support Final Determination Date for such Margin Support Period.

(e) The $145 million threshold level described in Section 2.8(b) will be reduced by:

(i) the amount of any rent accrued by any NT Entity with respect to such Margin Support Period pursuant to a Sale and Leaseback Transaction; and

(ii) an amount equal to the Earnout Threshold Adjustment, if any, for such Margin Support Period.

(f) For the purposes of calculating the Margin Support Payment, if any, due for the Margin Support Periods:

(i) charges to NTE’s combined net income for annual selling, general and administrative expenses shall be equal to the amount of such expenses as determined in accordance with GAAP and applicable regulations under the Securities Exchange Act of 1934; and

(ii) NTE’s expense allocation accounting principles in determining its selling, general and administrative expenses will, to the extent consistent with Section 2.8(f)(i), also be consistent with expense allocation accounting principles utilized by MPC in the historical preparation of financial statements for the Businesses.

(g) Any Margin Support Payment made by MPC to NTE shall be treated as an adjustment to the Purchase Price.

Section 2.9 Transfer of Funds.

All amounts due to any party under this Formation Agreement or any Related Agreement shall be made by wire transfer of immediately available funds (federal) to such account as designated by the receiving party no less than three (3) Business Days prior to the scheduled payment date.

The Debt Commitment Letters are in effect as of the Execution Date and neither NTI nor any of its Affiliates has agreed to any material amendment or modification to any of the Debt Commitment Letters that would adversely affect the ability of NTI to obtain the Debt Financing as contemplated thereby and neither NTI nor any of its Affiliates is in material breach or default thereunder.

Section 4.7 NTI Status; Investment.

(a) NTI understands that the Common Interests to be received pursuant to this Formation Agreement have not been registered under the 1933 Act, or under any applicable state securities laws, and neither MPC nor NT Holdco has any obligation to register the Common Interests under the 1933 Act or to register or qualify the offer or sale of the Common Interests with any state on the basis that the offering is exempt from registration under the 1933 Act and the rules and regulations promulgated thereunder. NTI further acknowledges that the Common Interests cannot be sold, assigned, or otherwise transferred unless subsequently registered under the 1933 Act and under applicable state securities laws or if an exemption from registration or qualification is then available. NTI understands that there is not, nor is there likely to be, a public market for the Common Interests and represents that it can afford to hold such Common Interests for an indefinite period of time.

(b) NTI is acquiring the Common Interests for its own account with the present intention of holding such securities for investment purposes and not with a view to, or for sale in connection with, any distribution of such securities in violation of any federal or state securities laws.

(a) From and after the Closing Date, MPC and SSA agree, jointly and severally, to indemnify, defend and hold harmless the NTI Indemnitees, from and against any and all Claims and Losses actually suffered or incurred by any of them to the extent arising out of, resulting from or relating to:

(i) the breach of any representation or warranty of MPC or SSA contained in this Formation Agreement;

(ii) the breach of any covenant or agreement of MPC or SSA contained in this Formation Agreement;

(iii) except as otherwise expressly provided under the Refining Contribution Agreement or the Marketing Contribution Agreement, the ownership or operation of the Acquired Entities prior to the Effective Time; or

(iv) in respect of any Claim for Taxes imposed on, or pertaining or attributable to, NT Holdco, the Acquired Entities and their respective assets and operations relating to any period (or portion thereof) ending on or prior to the Effective Time.

(b) Neither MPC nor SSA shall be liable for indemnification pursuant to Section 5.2(a)(i) with respect to Losses resulting from any breach by MPC or SSA or the representations and warranties in Section 3.5 or Section 3.6 unless the aggregate amount of all Representation and Warranty Losses, taken together, shall exceed the Indemnification Deductible after which point MPC and SSA will be obligated only to indemnify, defend and hold harmless the NTI Indemnitees from and against such Claims and Losses to the extent they, together with any and all Representation and Warranty Losses to be indemnified, exceed the Indemnification Deductible but are less than or equal to the Indemnification Ceiling. For the avoidance of doubt, the full amount of the Indemnification Ceiling shall be recoverable over and

Execution Copy

above the Indemnification Deductible. Notwithstanding the preceding, the limitations on MPC’s and SSA’s indemnification obligations set forth in the preceding sentences of this Section 5.2(b) shall not apply to Losses resulting from fraud by MPC or SSA in connection with this Formation Agreement.

Section 5.3 Indemnification by NTI.

From and after the Closing Date, NTI agrees to indemnify, defend and hold harmless the MPC Indemnitees from and against any and all Claims and Losses actually suffered or incurred by any of them to the extent arising out of, resulting from or relating to:

NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS FORMATION AGREEMENT, EXCEPT IN THE CASE OF FRAUD, NO PARTY SHALL BE ENTITLED TO RECOVER FROM ANY OTHER PARTY ANY AMOUNT IN RESPECT OF EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES EXCEPT TO THE EXTENT SUCH DAMAGES (A) ARE PAID OR OWNING TO A THIRD PERSON WITH RESPECT TO A THIRD-PARTY CLAIM OR (B) (1) CONSTITUTE CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS) OR DIMINUTION IN VALUE DAMAGES THAT WERE THE DIRECT AND REASONABLY FORESEEABLE CONSEQUENCES OF THE RELEVANT BREACH, (2) THE DAMAGES RESULTING FROM THE RELEVANT BREACH OF REPRESENTATIONS AND WARRANTIES IN ARTICLE 3 OR COVENANTS IN SECTION 7.1 EXCEED (X) $3,000,000 IF SUCH BREACH RELATED TO REPRESENTATIONS AND WARRANTIES CONCERNING THE MPC TRANSFERRED ASSETS OR THE REFINERY BUSINESS OR (Y) $1,000,000 IN ALL OTHER CASES AND (3) THE CLAIM ASSERTING THE RELEVANT BREACH IS DELIVERED ON OR PRIOR TO THE SECOND ANNIVERSARY OF THE CLOSING DATE. EXCEPT IN THE CASE OF FRAUD, ALL RELEASES, DISCLAIMERS, LIMITATIONS ON LIABILITY AND INDEMNITIES IN THIS FORMATION AGREEMENT, INCLUDING THOSE IN THIS ARTICLE 5, SHALL APPLY EVEN IN THE EVENT OF THE SOLE, JOINT, AND/OR CONCURRENT, ACTIVE OR PASSIVE NEGLIGENCE, STRICT LIABILITY OR FAULT OF THE PARTY WHOSE LIABILITY IS RELEASED, DISCLAIMED, LIMITED OR INDEMNIFIED (EXCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT).

Section 5.5 Indemnification Procedures.

(a) A MPC Indemnitee or NTI Indemnitee, as the case may be (for purposes of this Section 5.5, the “Indemnified Party”), shall give the indemnifying party under Section 5.2 and Section 5.3, as applicable (for purposes of this Section 5.5, the “Indemnifying Party”), prompt written notice of any matter which it has determined has given or could reasonably be expected to give rise to a right of indemnification under this Formation Agreement, containing a reference to the provisions of this Formation Agreement in respect of which such right of indemnification is claimed or arises; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from its obligations under this Article 5 except to the extent the Indemnifying Party is actually prejudiced by such failure. Notwithstanding anything to the contrary contained herein, the rights and remedies of the Indemnified Parties from and after the Closing shall not be limited by the fact that any Indemnified Party had knowledge of any breach, event or circumstance prior to the Closing or waived any condition to the Closing related thereto.

(b) If any Third Person shall notify an Indemnified Party with respect to a Third-Party Claim under this Article 5, then the Indemnified Party shall promptly notify the Indemnifying Party thereof in writing; provided, however, that the failure to provide such notice shall not release the Indemnifying Party from its obligations under this Article 5 except to the extent the Indemnifying Party is actually prejudiced by such failure.

(c) The Indemnifying Party will have the right to assume and thereafter conduct the defense of the Third-Party Claim with counsel of its choice reasonably satisfactory to the Indemnified Party; provided that (i) the Indemnifying Party must acknowledge in writing its obligation to indemnify the Indemnified Party in full without reservations with respect to such Third-Party Claim, (ii) the Third-Party Claim does not seek to impose any liability on the Indemnified Party other than money damages and (iii) the Third-Party Claim is not part of a larger claim or series of related claims that do not relate to Losses hereunder. The Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third-Party Claim without the prior written consent of the Indemnified Party (which consent may not be unreasonably withheld, conditioned or delayed) unless the judgment or proposed settlement involves only the payment of money damages by the Indemnifying Party, does not impose an injunction or other equitable relief or any other obligations upon the Indemnified Party, and provides for the full, final and unqualified release of the Indemnified Party in respect of such Third-Party Claim.

(d) Unless and until the Indemnifying Party assumes the defense of the Third-Party Claim as provided in Section 5.5(c), the Indemnified Party may defend against the Third-Party Claim in any manner it may reasonably deem appropriate. The Indemnifying Party shall be liable for the reasonable fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense thereof in accordance with this Formation Agreement or during the period in which the Indemnified Party’s legal counsel shall have advised the Indemnified Party that there exists one or more legal or

Execution Copy

equitable defenses available to them or that a conflict of interest exists that would make it inappropriate under applicable standards of professional conduct to have common counsel.

(e) If the Indemnifying Party assumes the defense of the Third-Party Claim as provided in Section 5.5(c), in no event will the Indemnified Party consent to the entry of any judgment or enter into any settlement with respect to the Third-Party Claim without the prior written consent of the Indemnifying Party (which consent may not be unreasonably withheld, conditioned or delayed).

ARTICLE 6

EMPLOYEE MATTERS

Section 6.1 Employment Offers.

(a) As soon as practicable after the execution of this Formation Agreement, NTI shall have the opportunity to make presentations regarding potential future employment with NTE, SPP Refining, NT Retail and NT Bakery to the Employees as a group as well as individually, all in accordance with a protocol to be agreed upon between MPC, SSA and NTI, and with respect to Active Represented Employees covered by the CBAs, in accordance with the CBAs and, in any case, with applicable federal and state labor law.

(b) As of the Closing Date, those Employees supplying operational services at the various Assets’ and Businesses’ locations will remain as employees of MPC, SSA or SuperMom’s, as applicable, pursuant to the Services Agreement, until the applicable Employee Transfer Date. Each “Employee Transfer Date” shall be determined in the following manner: an Employee Transfer Date shall be any date(s) on or after Closing on which NTI elects to transfer one of the designated group(s) of Acquired Employees to employment with an NT Entity, provided that the process described below with respect to any such group(s) of Acquired Employees (as defined below) has been completed. To ensure the integrity of MPC, SSA and SuperMom’s secure systems, NTI shall deliver a written notice to MPC or SSA, as applicable, at least twenty (20) Business Days prior to a proposed Employee Transfer Date setting forth its reasonable, good faith belief that the security-related and other conditions for such Acquired Employees’ transfer, as set forth in Schedule 6.1(b)(ii), have been satisfied (a “Security Completion Statement”). On or prior to the tenth Business Day following receipt of a Security Completion Statement by MPC or SSA, such entity shall deliver to NTI either a notice indicating that it accepts NTI’s Security Completion Statement or a written statement specifying those items with which it disagrees in such Security Completion Statement (a “Security Completion Objection Notice”). If MPC or SSA delivers a Security Completion Objection Notice or fails to timely agree to the Security Completion Statement, MPC, SSA and NTI shall consult in good faith and use Commercially Reasonable Efforts to resolve any objections contained therein. If such objections cannot be resolved pursuant to this paragraph, the Employee Transfer Date for the designated group(s) of Employees may occur either on the Employee Transfer Date initially proposed by NTI or a date thereafter that NTI selects; provided, that, if the applicable NT Entity proceeds with such transfer, MPC or SSA, as applicable, may without liability to NTE or its Subsidiaries, including any liability pursuant to the Services Agreement, terminate effective as of

Execution Copy

such Employee Transfer Date the Transition Services designated as being adversely effected in the Security Completion Objection Notice. For the avoidance of doubt, the Parties acknowledge that the Employee Transfer Date may be different for certain Employee groups, but not for Employees within the same Employee group provided, however, that the transfer of Employees in certain employee groups (including Employees in departments such as accounting, finance and procurement) may be delayed to assist in the maintenance of the integrity of MPC, SSA and SuperMom’s secure systems.

On or about forty-five (45) days prior to each of NTI’s proposed Employee Transfer Date(s), NTI will provide written notice of the proposed Employee Transfer Date to MPC, SSA and SuperMom’s. (The parties hereto understand and agree that such notice shall be without prejudice to the process described above for setting the actual Employee Transfer Date.) Within five (5) Business Days of receipt of such notice, MPC or SSA shall provide NTE with an updated list of Employees that includes the information, as of the date of delivery of such list, described in Section 4.22(a) of the Refining Contribution Agreement, Section 4.17(a) of the Marketing Contribution Agreement and Section 4.13(a) of the SuperMom’s Contribution Agreement.

In accordance with the CBAs and, in any case, with applicable federal and state labor law, no later than thirty (30) days prior to the applicable proposed Employee Transfer Date, NTE or its Subsidiaries shall offer employment, effective as of the applicable Employee Transfer Date, to all Active Represented Employees who are not on a leave approved by MPC, SSA or their Affiliates (a “Company-Approved Leave”) as of the date that NTE or its Subsidiaries makes such offers. Active Represented Employees who, as of the date offers are made, are on Company-Approved Leave that has or is expected to continue for at least one hundred eighty (180) days from the first day of such leave shall not become employees of NTE or its Subsidiaries. NTE or its Subsidiaries shall offer employment to each Active Represented Employee who, as of the date such offers are made, is on Company-Approved Leave that is expected to continue for less than one hundred and eighty (180) days from the first day of such leave, provided that MPC provides NTE with adequate assurance, as reasonably determined by NTE, that such employee will return from leave within one hundred eighty (180) days of the first day of such employee’s leave while employed by MPC, SSA or their Affiliates. With respect to any other Employees, no later than thirty (30) days prior to the applicable proposed Employee Transfer Date, NTE or its Subsidiaries shall offer employment to such Employees who meet NTE’s minimum hiring requirements and who are not on Company-Approved Leave as of the date that NTE or its Subsidiaries makes such offers. Such other Employees who, as of the date offers are made, are on Company-Approved Leave that has or is expected to continue for at least six (6) months from the first day of such leave shall not become employees of NTE or its Subsidiaries. NTE or its Subsidiaries shall offer employment to each such other Employee who meets NTE’s minimum hiring requirements and who, as of the date such offers are made, is on Company-Approved Leave that is expected to continue for less than six (6) months from the first day of such leave, provided that MPC provides NTE with adequate assurance, as reasonably determined by NTE, that such employee will return from leave within six months of the first day of such employee’s leave while employed by MPC, SSA or their Affiliates. For the avoidance of doubt, any Employee who does not receive an offer of employment pursuant to this Section

Execution Copy

6.1(b) or who declines an offer made pursuant to this Section 6.1(b) shall not become an employee of NTE or its Subsidiaries.

Offers of employment for Employees other than Active Represented Employees shall reflect (1) base salaries or base wages that shall be at least equal to those provided by MPC, SSA or SuperMom’s, as applicable, immediately prior to such offers, and (2) benefits (excluding incentive compensation), that are comparable in the aggregate, to those provided by MPC, SSA or SuperMom’s, as applicable, immediately prior to such offers. For purposes of the preceding sentence, comparability shall be determined with respect to the selected Refinery Employees, the selected SSA Employees and the selected SuperMom’s Employees as separate groups (rather than on an individual Employee basis or on the basis of all Employees as a single group). NTE or its Subsidiaries shall employ each Employee who accepts such offer of employment, provided that nothing herein shall require the continued employment of any Employee after the applicable Employee Transfer Date or shall limit the right of NTE or its Subsidiaries from changing any such Employee’s rate of base salary or base wages or benefits (except that neither NTE nor its Subsidiaries shall lower any Acquired Employee’s base salary or base wages for ninety (90) days following the applicable Employee Transfer Date). All Employees who accept employment with NTE or its Subsidiaries pursuant to the offers described in this Section 6.1 are sometimes referred to herein as “Acquired Employees,” Acquired Employees who are Active Represented Employees are sometimes referred to herein as “Acquired Represented Employees,” and Acquired Employees who are not Active Represented Employees are sometimes referred to herein as “Acquired Non-Represented Employees.” All employment offers made in accordance with this Section 6.1 by NTE or its Subsidiaries to Employees (other than Active Represented Employees) shall be made with sufficient time to give the Employees to whom such offers are made reasonable time to evaluate the offers (and in no event less than thirty (30) days prior to the applicable Employee Transfer Date). NTE shall also notify MPC, SSA and SuperMom’s, at least thirty (30) days prior to the applicable Employee Transfer Date, of the names of any Employees, including Active Represented Employees, to whom NTE or its Subsidiaries will not extend an offer of employment. Notwithstanding anything to the contrary in this Formation Agreement, prior to the applicable Employee Transfer Date, MPC shall have the right to offer continued employment with MPC, SSA or any of their Affiliates to any of the Employees identified in Schedule 6.1.

Section 6.2 Union Recognition.

(a) SPP Refining (or the Affiliate thereof that employs the Acquired Represented Refinery Employees) will recognize the Union as the exclusive representative of the Acquired Represented Refinery Employees and will assume on the applicable Employee Transfer Date of any Acquired Represented Refinery Employee the CBA governing the terms and conditions of employment of the Acquired Represented Refinery Employees. NT Bakery (or the Affiliate thereof that employs the Acquired Represented SuperMom’s Employees) will recognize the Union as the exclusive representative of the Acquired Represented SuperMom’s Employees and will assume on the applicable Employee Transfer Date of any Acquired Represented SuperMom’s Employee the CBA governing the terms and conditions of employment of the Acquired Represented SuperMom’s Employees.

Execution Copy

(b) On the Execution Date, the Parties will jointly notify the Unions of the execution of this Formation Agreement and the Related Agreements, which notification shall state that MPC and SuperMom’s are willing to bargain over the effects of the Contemplated Transactions on the Active Represented Employees.

Section 6.3 Benefits Plans, Employment Practices and Pay Practices.

(a) Unless otherwise provided by the terms of the MPC/SSA Benefit Plans or this Formation Agreement, participation as an active employee in MPC/SSA Benefit Plans, employment policies and employment practices shall end as of the applicable Employee Transfer Date for Employees whose employment with MPC, SSA or SuperMom’s ends as a result of the Contemplated Transactions. As of the applicable Employee Transfer Date, SuperMom’s shall no longer be a participating employer in SSA’s employee benefit plans, employment policies and pay practices. MPC or SSA shall be responsible for and shall continue to pay all hospital, medical, disability and other welfare plan benefits and expenses under each MPC/SSA Benefit Plan with respect to claims incurred prior to the applicable Employee Transfer Date, including any incurred but unreported claims incurred under any medical plan maintained by MPC or SSA. For purposes of this Section 6.3(a), a claim is deemed to have been incurred when services for the claim occurred, and all claims incurred during a continuous period of hospitalization shall be deemed to have occurred upon the commencement of such period. For the avoidance of doubt, neither NT Holdco nor any of its Affiliates shall assume sponsorship of, maintain or contribute to or assume any liability under or related to any Benefit Plan sponsored, maintained or contributed to by MPC, SSA or their ERISA Affiliates or other Affiliates as a result of the Contemplated Transactions. Effective as of the applicable Employee Transfer Date, NTE or its Affiliates shall offer the Acquired Employees participation in their Benefit Plans based on the terms and conditions of such plans and such Acquired Employees will be covered by NTE’s or its Affiliates employment policies and pay practices. On the applicable Employee Transfer Date, NTE and its Affiliates will recognize each Acquired Employee’s recognized service for eligibility and vesting purposes only, and with respect to vacation only, for benefit accrual purposes, under its qualified and welfare Benefit Plans and employment practices, and will maintain, for the remainder of the calendar year in which the applicable Employee Transfer Date occurs, the accrual rate for vacation in effect immediately prior to the offers. The existing vacation policies of MPC and SSA shall be observed for the balance of the year in which the applicable Employee Transfer Date occurs for Acquired Employees. MPC, SSA or SuperMom’s, as applicable, shall provide or cause to be provided, within ten (10) days after the applicable Employee Transfer Date, adequate data as NTE may reasonably request to implement the provisions of the preceding two sentences. To the extent that an Acquired Employee is entitled under any applicable Law or any policy of MPC, SSA or SuperMom’s to be paid for any vacation days accrued or earned but not yet taken by such Acquired Employee as of the applicable Employee Transfer Date, MPC, SSA or SuperMom’s shall discharge the liability for such vacation days. Without limiting the scope of the foregoing, if the applicable Employee Transfer Date occurs during an Acquired Employee’s participation in any MPC Benefit Plan or SSA Benefit Plan that provides for tuition reimbursement, any liability or obligation thereunder with respect to such Acquired Employee shall remain the obligation of MPC or SSA, as applicable. For purposes of an Acquired Employee who is participating in any MPC Benefit

Execution Copy

Plan or SSA Benefit Plan that provides for tuition reimbursement immediately prior to the applicable Employee Transfer Date, MPC or SSA, as applicable, shall continue to pay, in accordance with such plan, the reimbursements for the then current covered class(es). MPC and SSA shall not be responsible for tuition reimbursement for classes or programs which commence on or after the applicable Employee Transfer Date. NTE and its Affiliates shall not be responsible for tuition reimbursement or any liability or obligation under any MPC Benefit Plan or SSA Benefit Plan that provides for tuition reimbursement.

(b) NTE or its Affiliates shall (i) waive all limitations as to preexisting conditions, exclusions and waiting periods and actively-at-work requirements with respect to participation and coverage requirements applicable to the Acquired Employees and their dependents under its Benefit Plans to the extent satisfied or waived under the applicable corresponding MPC or SSA Benefit Plan immediately prior to the applicable Employee Transfer Date and (ii) provide each Acquired Employee and his or her eligible dependents with either pro-rated deductibles and co-payments for the balance of the calendar year or credit for any co-payments and deductibles paid prior to the applicable Employee Transfer Date in the calendar year in which the applicable Employee Transfer Date occurs for purposes of satisfying any applicable deductible or out-of-pocket requirements under any Benefit Plans in which the Acquired Employees participate. If credit for deductibles and co-payments is provided, MPC or SSA, as applicable, shall use Commercially Reasonable Efforts to provide or cause to be provided within fifteen (15) Business Days following the applicable Employee Transfer Date, adequate data to implement that credit as NTE may reasonably request.

(c) Effective as of the applicable Employee Transfer Date, NTE or its Affiliates shall be solely responsible for compliance with the requirements of COBRA for all Acquired Employees and their eligible dependents. MPC or SSA shall continue to be solely responsible for compliance with the requirements of COBRA for all persons who are not Acquired Employees or their eligible dependents for whom a qualifying event has occurred on or before the applicable Employee Transfer Date. For purposes of this Section 6.3(c), the terms “continuation coverage” and “qualifying event” shall have the meanings ascribed to them in COBRA.

(d) MPC and SSA shall retain and shall remain liable for the provision of retiree health and welfare benefits under the MPC/SSA Benefit Plans that provide such benefits to Employees (and their covered dependents) who retire effective prior to the applicable Employee Transfer Date.

(e) MPC and SSA agree to pay to all eligible Acquired Employees any bonuses or other amounts earned and due and payable under the MPC and SSA Annual Cash Bonus plan and the Success Through People plan for the calendar year in which the Closing occurs. NT Holdco shall reimburse, or cause its Affiliates to reimburse, MPC, SSA and SuperMom’s for the pro-rata portion of such bonus payments or other amounts attributable to the portion of the calendar year of the Closing following the Effective Time to the extent such reimbursement is not duplicative of amounts payable for the Operations Services under the Services Agreement.

Execution Copy

(f) During the period beginning on the Execution Date and ending on the last Employee Transfer Date, MPC and SSA shall provide NTE with copies of all amendments to the MPC/SSA Benefit Plans.

Section 6.4 Administration.

MPC, SSA and NTE shall take all actions which may be reasonably necessary in order to effectuate the transactions contemplated by this Article 6, including exchanging information and data relating to workers’ compensation, employee benefits and employee benefit plan coverages (except to the extent prohibited by applicable Law), and making all necessary filings and submissions to appropriate governmental agencies.

Section 6.5 WARN Act.

NT Holdco, NTE, SPP Refining, NT Retail and NT Bakery shall indemnify, defend and hold harmless the MPC/SSA Indemnitees against all liabilities arising out of the notification or other requirements under the WARN Act with respect to the Acquired Employees in connection with actions taken by NT Holdco, NTE, SPP Refining, NT Retail or NT Bakery on or after the applicable Employee Transfer Date or any other events that occur on or after the applicable Employee Transfer Date that give rise to any notification or other requirements under the WARN Act, except for any actions taken to effectuate the transactions contemplated herein or the events contemplated hereby on the Employee Transfer Date(s). MPC and SSA shall indemnify, defend and hold harmless the NT Holdco Indemnitees against all liabilities arising out of the notification or other requirements of the WARN Act with respect to the Acquired Employees in connection with actions taken by MPC, SSA or their Affiliates that occur prior to the applicable Employee Transfer Date that give rise to any notification or other requirements under the WARN Act or any other events that occur prior to the applicable Employee Transfer Date that give rise to any notification or other requirements under the WARN Act, except for any actions taken to effectuate the transactions contemplated herein or the events contemplated hereby on the Employee Transfer Date(s).

Section 6.6 Workers’ Compensation.

MPC and SSA shall maintain coverage for and be responsible for all liabilities arising out of Workers’ Compensation Matters involving the Acquired Employees to the extent the incident or alleged incident giving rise to the Worker’s Compensation Matter occurred prior to the applicable Employee Transfer Date and shall indemnify NTE and its Affiliates for any liabilities associated with such incidents. NTE or its Affiliates shall provide coverage for Workers’ Compensation Matters involving the Acquired Employees to the extent the incident or alleged incident giving rise to the Worker’s Compensation Matter occurred on or after the applicable Employee Transfer Date and shall indemnify MPC, SSA and their Affiliates for any liabilities associated with such incidents. MPC and SSA and NT Holdco, NTE, SPP Refining, NT Retail or NT Bakery shall provide each other reasonable access to all information reasonably necessary to adjudicate, process and administer Claims relating to any Workers’ Compensation Matters. In the event of doubt as to the date of the occurrence of the incident or alleged incident, NTE or its

Execution Copy

Affiliates shall process the Claim; provided, however, the processing of such Worker’s Compensation Matter shall not alter the allocation of responsibility for the Claim provided in the preceding sentences. In such case, NT Holdco, NTE, SPP Refining, NT Retail or NT Bakery and MPC or SSA, as the case may be, will agree on an equitable manner to allocate the actual liability.

Section 6.7 Post-Closing Non-Solicitation.

(a) Each of MPC and SSA agrees that, during the period from the Closing Date through the third anniversary thereof, it will not (and they will cause their Affiliates not to) solicit any Acquired Employee or any other employee of NTI and its Subsidiaries for employment with MPC, SSA or any of their Affiliates; provided, however, that the foregoing shall not prohibit (i) MPC, SSA or any one or more of their Affiliates from soliciting for employment any such person whose employment with NTI and its Subsidiaries has been terminated or has otherwise ended; or (ii) solicitations made by MPC, SSA or any one or more of their Affiliates to the public or to employees in any or all of the refining, terminaling, pipeline transportation or retail marketing segments of the petroleum refining and marketing industry generally.

(b) NTI agrees that, during the period from the Closing Date through the third anniversary thereof, it will not (and it will cause its Subsidiaries not to) solicit any employees of MPC or SSA for employment with NTI or any of its Subsidiaries; provided, however, that the foregoing shall not prohibit (i) the solicitation and hiring of Employees as contemplated by this Article 6, (ii) NTI or any one or more of its Subsidiaries from soliciting for employment or hiring any such person whose employment with MPC or SSA has been terminated or has otherwise ended; or (iii) solicitations made by NTI or any one or more of its Subsidiaries to the public or to employees in any or all of the refining, terminaling, pipeline transportation or retail marketing segments of the petroleum refining and marketing industry generally.

Section 6.8 Certain Post-Closing Matters Relating to Employees.

Except (a) as set forth on Section 6.8 of the Disclosure Schedules, (b) as otherwise expressly contemplated by this Formation Agreement or (c) as otherwise consented to by NTI in writing, such consent not to be unreasonably withheld, conditioned or delayed, during the period beginning on the Closing Date and ending on the applicable Employee Transfer Date, MPC and SSA shall not, and shall cause their Affiliates, to not:

(i) enter into any new CBAs or other collective bargaining agreements, memorandums of understanding or any other labor agreements relating to the Employees; provided that MPC, SSA and SuperMom’s may enter into grievance settlements that only entail the payment of money by MPC, SSA or SuperMom’s and which would not establish any precedent or any agreement with any union;

Execution Copy

(ii) except in the ordinary course of business consistent with past practice, increase in any manner the base compensation or other fringe, incentive, equity incentive, pension, retirement allowance, welfare or other employee benefits payable or to become payable to, or enter into any new employee benefits agreement or arrangement with, any Employee or promise to commit to undertake any of the foregoing in the future; and

(iii) except in the ordinary course of business consistent with past practice, take any action to cause or which could reasonably be expected to cause, any Employee who would otherwise be an Acquired Employee not to be such an employee (other than termination for cause).

Section 6.9 No Third-Party Beneficiaries.

Nothing expressed or implied in this Formation Agreement is intended to confer upon or deny any employee of the Refinery Business, SuperMom’s or the Marketing Business any rights or remedies, including any rights of employment for any specified period of time. Nothing express or implied in this Formation Agreement amends, or is intended to amend, any Benefit Plan.

Section 7.4 Access to Information.

During the Interim Period, NTI and its Representatives (including its legal advisors and accountants) and Debt Financing Sources shall be entitled to make such reasonable investigation and examination of MPC, SSA, Minnesota Pipe Line Company, MPL Investments, SuperMom’s and SAF’s business, operations and properties as NTI reasonably requests in connection with the Contemplated Transactions. The investigation shall include reasonable access to the properties, personnel, documents and books and records related to the Businesses, the Minnesota Pipe Line Interests and the Acquired Entities. MPC shall, and shall cause its Affiliates and Subsidiaries to, furnish such information about MPC, SSA, the Acquired Entities, Minnesota Pipe Line Company, MPL Investments, the Assets and the Businesses as NTI and its Representatives shall reasonably request, including financial, operating, employee (including books, records, files and other documentation with respect to the Employees), and other data and information and copies of documents with respect to the Businesses, the Acquired Entities, the Minnesota Pipe Line Interests or Assets or any of the transactions contemplated by this Formation Agreement as NTI and its Representatives shall from time to time reasonably request.

MPC shall cause the officers, employees, consultants, agents, accountants, attorneys and other Representatives of MPC and its Affiliates and its and their Subsidiaries to cooperate with NTI and its Representatives and Debt Financing Sources in connection with such access and examination, and contacting third parties. NTI and its Representatives and Debt Financing Sources shall cooperate with MPC and SSA and their Affiliates and its and their Subsidiaries and shall use their Commercially Reasonable Efforts to minimize any disruption to the Businesses. Neither NTI nor any of the Debt Financing Sources shall conduct any Environmental Testing in connection with such confirmatory due diligence.

Section 7.5 Repairs.

(a) If during the Interim Period there shall have been any damage to or destruction of any of the Physical Assets (a “Pre-Closing Adverse Change”) and the cost to repair or replace such Physical Assets resulting from such Pre-Closing Adverse Change (the “Repair Estimate”) is estimated, as determined by the Parties in good faith and without regard to any insurance or other third party reimbursements, to be, individually or in the aggregate, $25,000,000 or less, then MPC or SSA, as applicable, shall repair or replace such Physical Assets with similar grade, quality and condition or as otherwise required by applicable Laws (the “Asset Repair”) and with reasonable promptness prior to the anticipated Closing Date at its sole

Execution Copy

cost. If MPC or SSA, as applicable, are unable to complete the Asset Repair prior to the anticipated Closing Date, (i) NTI, at its sole discretion, may elect to consummate the Closing prior to the completion of the Asset Repair, and MPC or SSA, as applicable, shall retain the obligation to complete the Asset Repair with reasonable promptness following the Closing Date and shall be obligated to pay all costs incurred in connection with the completion of, or related to, the Asset Repair, or (ii) NTI may consent, in its sole discretion, to an extension of the Termination Date (and thereby the Closing Date) by up to a maximum of sixty (60) days after the date that the Repair Estimate or estimated time required is agreed or determined to the extent necessary to complete such Asset Repair.

(b) In the event the Repair Estimate exceeds, individually or in the aggregate, $25,000,000, NTI shall have the option to terminate this Formation Agreement pursuant to Section 10.1(e), and in the event the Repair Estimate exceeds, individually or in the aggregate, $100,000,000, MPC shall also have the option to terminate this Formation Agreement pursuant to Section 10.1(e). If this Formation Agreement is not terminated pursuant to the foregoing sentence, MPC, SSA and NTI shall negotiate in good faith an adjustment to the Purchase Price (and Estimated Purchase Price) to compensate NTI for the losses resulting from the Pre-Closing Adverse Change. In the event the Parties are unable to agree on the amount of such adjustment within ten (10) days of the determination of the amount of the Repair Estimate, then the Parties will resolve such dispute in accordance with the procedure set forth in Appendix C.

(c) MPC, SSA and NTI shall negotiate in good faith the estimated amount and timing of any such Asset Repairs. In the event the Parties are unable to agree on the amount of the Repair Estimate or the estimated time to complete the Asset Repairs within ten (10) days of the occurrence of the damage or destruction, then the Parties will resolve such dispute in accordance with the procedures set forth in Appendix C.

Section 7.6 Taking of Purchased Assets.

In the event that prior to Closing there shall be instituted or threatened in writing any Proceeding or other governmental action, including eminent domain, condemnation or other governmental proceeding, that there is a reasonable probability of MPC, SSA, or NTI or its Affiliates after Closing, losing any portion of or interest in any of the Assets or the Minnesota Pipe Line Interests, MPC or SSA, as applicable, shall promptly notify NTI. NTI shall have the right to terminate this Formation Agreement pursuant to Section 10.1 within thirty (30) days from the date of such notice, by giving notice to MPC of its election to terminate this Formation Agreement if such Proceeding or other action has or there is a reasonable probability of a taking of a property or properties with an estimated fair market value, individually or in the aggregate, of $25,000,000 or more as reasonably determined by NTI and agreed to by MPC. If NTI is not entitled to or, if entitled, does not timely terminate this Formation Agreement, then MPC or SSA shall assign to NTE, or its Subsidiaries as applicable, at Closing any rights MPC or SSA may have to receive any payments, other than payments for losses incurred prior to Closing (such as payments for loss of Store revenues in the period before Closing), net of any reasonable, out-of-pocket third-party expenses, as a result of any such proceeding or other action. In the event the Parties are unable to agree on the fair market value of such property or properties within ten (10)

Execution Copy

days after MPC or SSA gives notice to NTI, then the Parties will resolve such dispute in accordance with the procedures set forth in Appendix C.

Section 7.7 Condition of Assets.

In consummating the purchase and the sale of the Assets contemplated hereunder, NTI acknowledges that it will become the owner of all of the common membership interests of NT Holdco, which will wholly own NTE and its subsidiaries and that these entities will own the Assets and that NTI shall accept such ownership of NT Holdco with its Assets (subject to the Obligations of MPC and SSA pursuant to Section 7.5 and Section 7.6) in their AS-IS, WHERE-IS CONDITION WITH ALL FAULTS (EXCEPT AS SET FORTH IN THE DEEDS AND ANY OTHER INSTRUMENT OF CONVEYANCE OR ASSIGNMENT), WITHOUT ANY EXPRESS OR IMPLIED COVENANT, WARRANTY AS TO TITLE, CONDITION (INCLUDING ANY ENVIRONMENTAL CONDITION), MERCHANTABILITY, PERFORMANCE, FITNESS (BOTH GENERALLY AND FOR ANY PARTICULAR PURPOSE) OR OTHERWISE (WHICH WARRANTIES MPC AND SSA HEREBY EXPRESSLY DISCLAIM), OR RECOURSE, OTHER THAN AS EXPRESSLY SET FORTH HEREIN OR IN THE RELATED AGREEMENTS. Without limiting the generality of the preceding sentence, the provisions of this Section 7.7 shall not alter, limit, modify or impair the representations and warranties of MPC and/or SSA contained in this Formation Agreement or the Related Agreements or any claims for fraud in connection with the Contemplated Transactions or this Formation Agreement or any of the Related Agreements.

Section 7.8 Independent Investigation.

EXCEPT FOR THE REPRESENTATIONS EXPRESSLY MADE IN OR PURSUANT TO THIS FORMATION AGREEMENT, ANY DEEDS OR OTHER ASSIGNMENT OR CONVEYANCE INSTRUMENT OR ANY OTHER RELATED AGREEMENTS, NTI ACKNOWLEDGES AND AGREES THAT: (i) THERE ARE NO REPRESENTATIONS, WARRANTIES, STATEMENTS, ASSURANCES OR GUARANTEES MADE BY OR ON BEHALF OF MPC, SSA OR ANY OF THEIR AFFILIATES, EXPRESS OR IMPLIED, AS TO (A) THE ASSETS, THE SUPERMOM’S ASSETS OR THE SAF ASSETS OR (B) THE OBLIGATIONS, BUSINESS, RESULTS OF OPERATIONS, CONDITION (FINANCIAL, ENVIRONMENTAL OR OTHERWISE) OR PROSPECTS RELATING TO THE BUSINESSES, AND THAT IN MAKING ITS DECISION TO ENTER INTO THIS FORMATION AGREEMENT AND TO CONSUMMATE THE PURCHASE OF THE INTERESTS AND SPP REFINING’S ASSUMPTION OF THE SPP REFINING ASSUMED MPC OBLIGATIONS AND NT RETAIL’S ASSUMPTION OF THE NT RETAIL ASSUMED SSA OBLIGATIONS, NTI HAS RELIED AND WILL RELY SOLELY UPON ITS OWN INDEPENDENT INVESTIGATION, VERIFICATION, ANALYSIS AND EVALUATION; (ii) EACH OF MPC AND SSA DISCLAIM ALL LIABILITY AND RESPONSIBILITY FOR ANY REPRESENTATION, WARRANTY, STATEMENT OR INFORMATION ORALLY OR IN WRITING MADE OR COMMUNICATED TO NTI INCLUDING ANY OPINION, INFORMATION OR ADVICE WHICH MAY HAVE BEEN PROVIDED TO NTI BY MPC, SSA OR ANY OF THEIR AFFILIATES OR REPRESENTATIVES (INCLUDING ANY

BACKCAST DATA OR MODELS PROVIDED BY MPC OR SSA, WHICH HAVE BEEN PROVIDED FOR ILLUSTRATION PURPOSES ONLY, ANY OTHER INFORMATION PROVIDED TO THE DATE OF THIS FORMATION AGREEMENT, ANY CORRESPONDENCE FROM MPC, SSA OR ANY OF THEIR AFFILIATES OR FROM ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & CO. INCORPORATED, AS ADVISORS TO MPC, SSA OR THEIR AFFILIATES, ANY PRESENTATION BY THE MANAGEMENT OF MPC, SSA OR ANY OF THEIR AFFILIATES AND ANY INFORMATION, DOCUMENT OR MATERIAL PROVIDED OR MADE AVAILABLE TO NTI, OR STATEMENTS MADE TO NTI DURING SITE OR OFFICE VISITS, IN ANY DATAROOMS OR MANAGEMENT PRESENTATIONS) OTHER THAN THOSE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS FORMATION AGREEMENT, ANY DEEDS OR OTHER ASSIGNMENT OR CONVEYANCE INSTRUMENT OR ANY OF THE OTHER RELATED AGREEMENTS; (iii) NEITHER MPC, SSA NOR ANY OF THEIR AFFILIATES HAVE MADE, AND EACH OF MPC AND SSA HEREBY EXPRESSLY DISCLAIM AND NEGATE, ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, FITNESS (BOTH GENERALLY AND FOR A PARTICULAR PURPOSE), OR CONFORMITY TO MODELS OR SAMPLES AND ANY OTHER REPRESENTATION OR WARRANTY, EXPRESS, STATUTORY OR IMPLIED, RELATING TO THE ASSETS OR THE BUSINESSES OTHER THAN THOSE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS FORMATION AGREEMENT AND THE RELATED AGREEMENTS; AND (iv) EACH OF MPC AND SSA MAKES NO REPRESENTATIONS OR WARRANTIES WITH RESPECT TO THE USE OR CONDITION (INCLUDING ENVIRONMENTAL USE OR CONDITION), THE PRESENCE OR ABSENCE OF HAZARDOUS SUBSTANCES AT, ON, UNDER OR ADJACENT TO ANY PORTION OF THE REFINERY ASSETS, THE MARKETING ASSETS OR THE SUPERMOM’S ASSETS, COMPLIANCE WITH APPLICABLE LAWS AND AUTHORIZATIONS OTHER THAN THOSE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS FORMATION AGREEMENT AND THE RELATED AGREEMENTS. The provisions of this Section 7.8 shall not alter, limit, modify or impair the representations and warranties of MPC and/or SSA contained in this Formation Agreement or the Related Agreements and shall not limit, alter or waive any claims for fraud in connection with this Formation Agreement or any of the Related Agreements and the Contemplated Transactions.

Section 7.9 Supplement to Disclosure Schedules.

Each of MPC and SSA may, from time to time prior to the Effective Time, by written notice to NTI, supplement or amend the Disclosure Schedules. If either MPC or SSA so supplements or amends the Disclosure Schedules, the Parties shall negotiate in good faith to agree upon an appropriate adjustment to the Purchase Price (and Estimated Purchase Price) or other reasonable remedy to reflect the information provided in the supplement or amendment (any such adjustment, a “Disclosure Adjustment”). If the Parties agree on a Disclosure Adjustment pursuant to this Section 7.9, NTI shall be deemed to waive any further right to make a Claim with respect to such supplement or amendment to the Disclosure Schedules. If the Parties fail to agree on a Disclosure Adjustment pursuant to this Section 7.9, such supplement or amendment to the Disclosure Schedules shall not affect or be deemed to modify any

Execution Copy

representation or warranty of MPC or SSA set forth in this Formation Agreement or any of the Related Agreements, any of the conditions to the obligations of NTI to consummate the Contemplated Transactions, or any of the remedies available to NTI or the NTI Indemnitees under this Formation Agreement or any of the Related Agreements, including any of their rights to indemnification hereunder or thereunder. For the avoidance of doubt, MPC or SSA may supplement or amend Sections 4.10(a)(iii) or 4.12(c) of the Refining Contribution Disclosure Schedules and Sections 4.10 or 4.12(c) Marketing Contribution Disclosure Schedules, to identify new Environmental Conditions that occur as a result of an incident occurring following the Execution Date but prior to the Effective Time, pursuant to the process described above (any such amendment, an “Environmental Disclosure Update”). If the Parties agree to a Disclosure Adjustment with respect to an Environmental Disclosure Update, the Environmental Condition described in such Environmental Disclosure Update shall be deemed to be a Known Marketing Environmental Condition or Known Refinery Environmental Condition for the purposes of the Related Agreements. If the Parties do not agree to a Disclosure Adjustment with respect to Environmental Disclosure Update, the information contained therein shall have the effect described in the fourth sentence of this paragraph.

Section 7.10 Title and Surveys.

(a) Title Commitments. MPC and SSA has caused the Title Company to issue (i) a current title commitment with respect to the Refinery Real Property (together with any updates thereto, the “Refinery Title Commitment”) and (ii) current title commitments with respect to each Marketing Site (collectively, together with any updates thereto, the “Marketing Title Commitments”). Each of the Refinery Title Commitment and the Marketing Title Commitments shall set forth the state of title to the applicable real property fee or leasehold interest, together with all exceptions or conditions to such title which are of record or otherwise known to the Title Company, including all easements, restrictions, rights-of-way, covenants, reservations and all other encumbrances affecting the applicable real property interests, which may appear in the Refinery Title Policy or the applicable Marketing Title Policy, as applicable, if issued. Each of the Refinery Title Commitment and the Marketing Title Commitments when issued shall be accompanied by the most legible copies available of all such exceptions and conditions shown therein (the “Title Exception Documents”). The Refinery Title Commitment shall contain the express commitment of the Title Company to issue the Refinery Title Policy, and the Marketing Title Commitments shall each contain the express commitment of the Title Company to issue the applicable Marketing Title Policy (including a corresponding Sale-Leaseback Leasehold Title Policy, if applicable), in each case in a minimum amount as set forth on Section 7.10(a) of the Disclosure Schedules, subject to customary conditions of Title Company in issuing such Title Policies, and also subject to any modifications or changes to any Survey, Refinery Title Commitment or Marketing Title Commitment made in accordance with this Formation Agreement. Notwithstanding anything to the contrary herein or in Appendix D, NTI may elect to obtain any Refinery Title Policy or any Marketing Title Policy, including any Sale-Leaseback Leasehold Title Policy, in an amount greater than the applicable amount set forth on Section 7.10(a) of the Disclosure Schedules; provided, however, that NTI shall pay the increased cost for any incremental title premiums incurred in excess of the premiums that would

Execution Copy

have been paid if NTI obtained Title Policies (including endorsements) in the amounts set forth on Section 7.10(a) of the Disclosure Schedules.

(b) Surveys. MPC and SSA shall obtain the Surveys of the Refinery Real Property and the Marketing Sites, as applicable. All Surveys shall be prepared by a licensed surveyor or professional engineer qualified to conduct surveys in the state where the property being surveyed is located. The Survey of the Refinery Real Property shall distinguish and clearly label each separate parcel that comprises Refinery Real Property owned by MPC, including any buffer properties; each separate parcel that comprises any Refinery Leased Real Property, including labeling such parcels as being leased; the parcel(s) of real property on which the SuperMom’s Facility is located; the boundaries of the Park Penta Site, including labeling such area as the Park Penta Site; and the location of the “marketing building” associated with the ▇▇▇▇▇▇ Products Plume. All Surveys will be subject to changes to any Survey, Refinery Title Commitment or Marketing Title Commitment made in accordance with this Formation Agreement, and will be acceptable to NTE and the Title Company for purposes of any permitted deletions or modifications to any exception for survey matters in the Refinery Title Policies or Marketing Title Policies (including a corresponding Sale-Leaseback Leasehold Title Policy, if applicable), and any loan policies. There will be a separate Survey for the Refinery Real Property and each of the Marketing Sites. The cost of the Surveys shall be paid in accordance with Appendix D to this Formation Agreement.

(c) NTI’s Title Objections. As to each of the Refinery Real Property and each of the Marketing Sites, MPC shall deliver, or cause the Title Company and any surveyor to deliver, to NTI the relevant Title Commitment, Title Exception Documents, and Survey (collectively, the “Title and Survey Documents”) as soon as reasonably practicable and promptly after the Title and Survey Documents has been prepared. NTI has furnished MPC a written notice with respect to each Marketing Real Property and the SuperMom’s Real Property setting forth all title defects, encumbrances, Liens or other matters (excluding the failure to obtain any third-party consent required under any Marketing Real Property Lease, which consents are addressed under other provisions of this Agreement) for which NTI, in its reasonable opinion, does not believe qualify as Permitted Liens (“Title Defects”), such notice being a “Title Objection Notice”. NTI shall have until October 8, 2010 to make any Title Objection Notice with respect to stores 4241 and 4317. Those title or survey objections identified by the Third Party to the Sale and Leaseback Transaction contained within the written notice from NTI described above, and with respect to stores 4241 and 4317, delivered on or prior to October 8, 2010, shall be deemed to have been made by NTI as Title Objection Notices hereunder. With respect to any Refinery Real Property (excluding the SuperMom’s Real Property), NTI shall deliver a Title Objection Notice for any title defects, encumbrances, Liens or other matters (excluding the failure to obtain any third-party consent required under any Marketing Real Property Lease, which consents are addressed under other provisions of this Agreement) no later than twenty (20) days after NTI’s receipt of all Survey and Title Documents related to any major segment of the Refinery Real Property (the major segments being the Cottage Grove Tank Farm, the refinery proper and the buffer properties). Notwithstanding anything to the contrary herein, without limiting the generality of the foregoing and in addition to any other Title Defects on the Refinery Real Property that NTI identifies, the following matter shall be deemed to be Title

Execution Copy

Defects: the failure to have recorded in the real property or other official records evidence of any city, village or other municipality vacating any road or alley on which any portion of the Refinery Real Property (other than any buffer properties) is situated. Except as expressly provided for herein, matters shown on the Surveys to which NTI does not object in its Title Objection Notices and other matters contained in the Title Commitments to which NTI does not timely object shall be deemed to be Permitted Liens.

(d) MPC and SSA Rights to Cure. MPC and SSA shall have until any time on or prior to Closing, at their cost and expense, if they so elect, but without Obligation, to cure all or a portion of such asserted Title Defects. Any asserted Title Defects which are waived (in writing) by NTI or cured within such time to NTI’s satisfaction shall be deemed Permitted Liens.

(e) Uncured Title Defects. If MPC or SSA is either unwilling or unable to cure any Title Defect, NTI may elect, on a property-by-property basis, to receive a credit against, or reduction of, the Purchase Price (and Estimated Purchase Price), as applicable, in an amount equal to the lesser of (i) the amount necessary to cure such Title Defect or (ii) the reduction in the fair market value of the property or properties caused by any such Title Defect, as reasonably determined by MPC and agreed to by NTI; provided, however, that if the Title Defects with respect to: (x) any property identified in Section 7.10(e) of the Disclosure Schedules, exceeds, either individually or collectively, 100% of the dollar value assigned to such property in Section 7.10(e) of the Disclosure Schedules, or if such Title Defects could prohibit the current use of or access to the subject property, then NTI may elect to exclude such property from the Contemplated Transactions, in which case such property will not be conveyed to NT Retail or the Third-Party to the Sale and Leaseback Transaction, as applicable, MPC or SSA, as applicable, will continue to own or hold the subject property, and the Purchase Price (and Estimated Purchase Price) will be reduced by the dollar value assigned to such property in Section 7.10(e) of the Disclosure Schedules; or (y) any other property, if such Title Defects could prohibit the current use of or access to the subject property, then NTI may elect to exclude such property from the Contemplated Transactions, in which case such property will not be conveyed to SPP Refining and MPC or SSA, as applicable, will continue to own or hold the subject property, and the Purchase Price will be reduced appropriately to reflect (i) for any property that is utilized to generate EBITDA for the Businesses, the reduction in the value of the Businesses being acquired based on the EBITDA generated by the Businesses attributable to the operations of the subject property, or (ii) for any property that is not utilized to generate EBITDA for the Businesses (by way of example but not limitation, buffer property), the assessed value for ad valorem tax purposes of such property. If NTI disagrees with MPC’s determination of the amount to cure any Title Defect with respect to any parcel of property, the reduction in market value attributable to any Title Defect of the subject property, or the reduction in the value of the Businesses attributable to the exclusion of the operations of the subject property, NTI shall use Commercially Reasonable Efforts to so advise MPC in writing within ten (10) Business Days after receipt of such written determination of such cost to cure and/or such reduction in fair market value, provided, however that if NTI has not responded within twenty (20) Business Days, it shall be deemed to have agreed to the estimate, and provided, further that during such twenty (20) Business Day period, MPC shall cooperate in good faith with NTI in its analysis of MPC’s determination of the amounts described in the immediately preceding sentence. In the

Execution Copy

event the Parties disagree over the amount of any such credit against the Purchase Price with respect to any such parcel of property, or as to whether any given matter is a valid Title Defect, then the Parties will resolve such disputes in accordance with the procedures set forth in Appendix C. To the extent the foregoing resolution of any such credit against the Purchase Price with respect to a property cannot be accomplished prior to Closing, the Parties shall resolve such issue post-Closing and MPC shall make a contribution to NT Holdco in an amount equal to the amount of such credit. In the event the determination of the credit against the Purchase Price attributable to Title Defects exceeds, individually or in the aggregate, $25,000,000, NTI shall have the option to terminate this Formation Agreement pursuant to Section 10.1(e) or waive this right and proceed with Closing. Notwithstanding anything to the contrary in this Section 7.10, NTI shall be permitted at any time prior to and after Closing to work with the Title Company and/or any surveyor to remove, insure around, revise or otherwise modify any matter shown on any Title Commitment or Survey, regardless of whether such matter is a Permitted Lien, an uncured Title Defect, or any other matter affecting the subject property.

Section 7.11 Franchise Arrangements.

review, and MPC shall provide, or cause to be provided, reasonable access to, such books and records to verify the accuracy of such amounts. Each such review shall be conducted at NTI’s sole expense and during normal business hours in a manner that does not unreasonably interfere with the operations of MPC or its Affiliates.

From and after the Closing, NTI agrees to cause NTE to defend, indemnify and hold harmless the MPC Indemnitees from and against any and all Losses caused by, arising out of, or in connection with, the performance by the MPC Indemnitees of the Interim Services, except to the extent such Losses result from the gross negligence or willful misconduct of any of the MPC Indemnitees and except for Claims and Losses for which MPC and SSA are obligated to provide indemnity pursuant to this Formation Agreement.

Section 11.8 Severability.

If any term or other provision of this Formation Agreement is invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Formation Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the Contemplated Transactions is not affected in any manner materially adverse to any Party.
