         Section 1.5 Reserved.

         Section 1.6 Adjustment to Purchase Price.

                           (a) As soon as possible following the Closing (but in
         any event within 15 days following the Closing), the Seller shall
         prepare and deliver to the Buyer a statement (the "Benchmark Working
         Capital Statement") setting forth the amount of Benchmark Working
         Capital (as defined below in Section 1.6(c)) and a statement (the
         "Final Working Capital Statement") setting forth the amount of Final
         Working Capital (as defined below in Section 1.6(c)). The Buyer shall
         have 15 days to review the Benchmark Working Capital Statement and the
         Final Working Capital Statement and supporting documentation and shall
         have reasonable access to the books, records and personnel of the
         Seller for purposes of verifying the accuracy of the calculation of
         Benchmark Working Capital and Final Working Capital. The Seller's
         calculation of Benchmark Working Capital and Final Working Capital
         shall be deemed final




                                       4
<PAGE>

         and binding unless the Buyer raises an objection in writing within 15
         days of its receipt thereof, specifying in reasonable detail the nature
         and extent of such objection. If the Buyer raises such an objection to
         the calculation of Benchmark Working Capital and Final Working Capital
         within such 15-day period, and if the Seller and the Buyer are unable
         to resolve such objection within 15 days of the date the Seller
         receives such objection, then the disputed matter shall be submitted
         for determination to PriceWaterhouseCoopers or such other accounting
         firm of national reputation mutually agreeable to the Seller and the
         Buyer, which shall have up to 10 days to render its determination with
         respect to such disputed matter. The determination of such accounting
         firm shall be final and binding for all purposes. The fees and expenses
         of such accounting firm shall be borne equally by the Seller and the
         Buyer.

                           (b) If Final Working Capital exceeds the Benchmark
         Working Capital, then the Buyer will pay the Seller the amount of such
         excess. If Final Working Capital is less than Benchmark Working
         Capital, then the Seller will pay the Buyer the amount of such
         shortfall. Any such payments will be made within 5 business days of the
         determination of the adjustment by wire transfer of immediately
         available funds and any such payments shall be deemed to be an
         adjustment to the Purchase Price.

                           (c) The following terms shall have the following
         meanings:

         "Benchmark Working Capital" shall mean the Working Capital on the close
of business on June 30, 2002 as determined pursuant to this Section 1.6 and in
accordance with the methodologies employed in the preparation of the balance
sheet attached hereto as Schedule 1.6.

         "Final Working Capital" shall mean the Working Capital on the close of
business on the Closing Date as determined pursuant to this Section 1.6 and in
accordance with the methodologies employed in the preparation of the balance
sheet attached hereto as Schedule 1.6.

         "Working Capital" shall mean the current assets minus current
liabilities of the Company and its Subsidiaries (on a pro forma consolidated
basis excluding the Excluded Subsidiaries, all intercompany accounts (except
trade receivables due to the Company or its Subsidiaries), and all income taxes
payable (or due under a tax sharing agreement) by the Company or its
Subsidiaries) determined in accordance with generally accepted accounting
principles as consistently applied by the Seller with respect to the businesses
contributed to the Company immediately prior to the date hereof.

                           (d) The Seller shall remit to the Buyer as soon as
         practicable after the receipt thereof any revenue received by the
         Seller or any affiliate of the Seller subsequent to the Closing that is
         attributable to the Assets.

                           (e) Notwithstanding anything herein to the contrary,
         the



                                       5
<PAGE>

         amounts payable to the Buyer pursuant to this Section 1.6 shall not be

         any Governmental Authority which would materially adversely affect the
         Company's or its Subsidiaries' use of such Real Property.

                  Section 2.12 Regulatory Matters.

                            (a) None of the Company or any of its Subsidiaries
         is a "Natural Gas Company" as that term is defined in Section 2 of the
         Natural Gas Act ("NGA"). None of the Company or its Subsidiaries is a
         "public utility company," "holding company" or "subsidiary" or
         "affiliate" of a holding company as such terms are defined in the
         Public Utility Holding Company Act of 1935 (the "1935 Act"). No
         approval of (i) the Securities and Exchange Commission under the 1935
         Act or (ii) FERC under the NGA, the Interstate Commerce Act ("ICA") or
         the Federal Power Act is required in connection with (x) the

         the ICA. MAPL is in material compliance with all applicable provisions
         of the ICA and all rules and regulations promulgated by FERC pursuant

         that pertain to terms and



                                       13

         conditions and rates charged for services.

                            (c) The Company and its Subsidiaries have all
         licenses, permits and authorizations (other than licenses or permits
         for the use of land) issued or granted by Governmental Authorities that
         are necessary for the conduct of the Company's and its Subsidiaries'
         businesses, as they are presently conducted and as conducted
         immediately prior to the Contributions, except for such failures that,
         individually or in the aggregate, would not reasonably be expected to
         have a Material Adverse Effect.

                  Section 2.13 Intellectual Property.

                            (a) Except as set forth on Schedule 2.13(a), and as
         may be identified during development of the IT Migration Plan (as
         defined in Section 4.12 below), and for such matters as would not have
         a Material Adverse Effect, each of the Company and its Subsidiaries
         owns all right, title and interest in and to, or has a valid and
         enforceable license or other right to use, all the Intellectual
         Property (as defined below) used by the Company in connection with its
         business, which represents all Intellectual Property rights necessary
         for the Company to conduct its business as presently conducted.

                            (b) Neither the Company nor any of its Subsidiaries
         has materially violated, infringed upon or unlawfully or wrongfully
         used the intellectual property of others, and neither of the Company's
         nor any of its Subsidiaries' Intellectual Property or any related
         rights as used in the businesses now or heretofore conducted by the
         Company or any of its Subsidiaries, materially infringes upon or
         otherwise materially violates the rights of others, nor has any person
         or Governmental Authority asserted in writing a material claim of such
         infringement or misuse or initiated (or indicated in writing any
         present or future intention to initiate) any material proceeding with
         respect to such Intellectual Property.

                            (c) Except as set forth on Schedule 2.13(c), neither
         the Company nor any of its Subsidiaries will from and after the Closing
         be obligated to make any payments for royalties, fees or otherwise to
         any person in connection with any of the Company's or any of its
         Subsidiaries' Intellectual Property. None of the Seller, the Company or
         any of its Subsidiaries is aware of any infringement of the Company's
         or any of its Subsidiaries' Intellectual Property, and there are no
         pending infringement actions against another for infringement of the
         Company's or any of its Subsidiaries' Intellectual Property or theft of
         trade secrets.

                            (d) The only representations and warranties given in
         respect of Intellectual Property and matters and agreements relating
         thereto are those contained in this Section 2.13, and none of the other
         representations and warranties shall be deemed to constitute, directly
         or indirectly, a representation and warranty in respect of Intellectual
         Property and matters or agreements relating



                                       14

         thereto.

                            (e) As used in this Agreement, "Intellectual
         Property" shall mean the trademarks, service marks, trade names,
         inventions, trade secrets, copyrights and domain names used in
         connection with the Company's or its Subsidiaries' businesses.

the Company and any Subsidiary and their assets, properties and operations.
Except as relates to Tax matters (which are provided for in Section 2.9), NGA,
ICA and the 1935 Act matters (which are provided for in Section 2.12) or
environmental, health and safety matters (which are provided for in Section
2.21), none of the Seller, the Seller's affiliates, the Company or its
Subsidiaries has materially violated, been charged with materially violating or,
to the knowledge of Seller or any of its affiliates, been threatened with a
charge of materially violating of any such law, license, regulation, order or
other legal requirement, or are in material default with respect to any material
order, writ, judgment, award, injunction or decree of any Governmental
Authority, in each case, as applicable to the Company, its Subsidiaries or any
of the Company's and its Subsidiaries' assets, properties or operations.

                   Section 2.15 Litigation. Except as set forth on Schedule
2.15, there are no Legal Proceedings (as hereinafter defined) pending or, to the
knowledge of the Seller, the Seller's affiliates, the Company or its
Subsidiaries, threatened against or involving the Seller, any of the Seller's
affiliates, the Company or any of its Subsidiaries that, individually or in the
aggregate, are reasonably likely to:

                            (a) incur damages or costs to the Company or any of

         and documents described in subsections (a) through (o) are hereinafter
         referred to collectively as the "Commitments" and individually as a
         "Commitment").

         Each Commitment is valid, binding and enforceable against the Company
and/or each Subsidiary of the Company that is a party thereto in accordance with
its terms, and in full force and effect on the date hereof (except to the extent
that its enforceability may be limited by applicable bankruptcy, insolvency,
reorganization or other similar law affecting the enforcement of creditors'
rights generally or by general equitable principles). The Company and each of
its Subsidiaries, as the case may be, have performed in all material respects
all obligations required to be performed by them under, and are not in material
default or breach of in respect of, any Commitment, and no event has occurred
which, with due notice or lapse of time or both, would constitute such a
default. To the knowledge of the Seller and the Company or any of its
Subsidiaries, no other party to any Commitment is in default in any material
respect thereof, and no event has occurred which, with due notice or lapse of
time or both, would constitute such a default. The Seller has made available to
the Buyer or its representatives true and complete originals or copies of all
the Commitments and a copy of every material default notice received by the
Seller or the Company or any of its Subsidiaries during the past one year with
respect to any of the Commitments.

                   Section 2.17 Books and Records of the Company. The books of
account, minute books, record books, and other records of the Company and its
Subsidiaries, all of which have been made available to the Buyer or its
representatives, are complete and correct in all material respects.

                   Section 2.18 Employee Plans.

                            (a) Except as set forth in Schedule 2.18(a), neither
         the Company nor any of its Subsidiaries' sponsors or maintains or has
         any liability or obligation with respect to, and at any time during the
         past five years or, if longer, for any period for which an applicable
         statute of limitations has not expired, has not sponsored, maintained
         or had any liability or obligation with respect to, any "employee
         benefit plan," as defined under Section 3(3) of the Employee Retirement
         Income Security Act of 1974, as amended ("ERISA"), or any other bonus,
         pension, stock option, stock purchase, benefit,

         welfare, profit-sharing, retirement, disability, vacation, severance,
         hospitalization, insurance, incentive, deferred compensation and other
         similar fringe or employee benefit plans, funds, programs or
         arrangements, whether written or oral ("Employee Plans"), in each of
         the foregoing cases which cover, are maintained for the benefit of, or
         relate to any or all current or former employees of the Company.
         Schedule 2.18(a) sets forth a true and complete list of all Employee
         Plans which cover, are maintained for the benefit of, or relate to any
         or all employees of the Seller or its affiliates who are assigned to or
         perform services primarily for the business of the Company or its
         Subsidiaries (including the business of operating the assets of
         Seminole) (the "Business Employees," and such Employee Plans
         hereinafter referred to as the "Seller Plans"). For purposes of
         determining Business Employees, a person shall be deemed to be
         performing services primarily for the business of the Company or any of
         its Subsidiaries if such person spends at least 50% of their working
         time in the conduct of the business of operations of the Company or its
         Subsidiaries.

                            (b) The Company and its Subsidiaries have no current
         or former employees. Schedule 2.18(b) sets forth a true and complete
         list showing the names of all Business Employees. Except as set forth
         on Schedule 2.18(b), there are no contracts, agreements, plans or
         arrangements covering any Business Employee with "change of control",
         severance or similar provisions that would be triggered as a result of
         the consummation of this Agreement or that could otherwise result in
         liability to the Company or its Subsidiaries. To the Seller's and the
         Company's knowledge, no Business Employee is obligated under any
         contract (including licenses, covenants or commitments of any nature)
         or other agreement, or subject to any judgment, decree or order of any
         court or administrative agency, that would interfere with the use of
         such employee's efforts to promote the interests of the Company or the
         Buyer or that would conflict with the Company's or its Subsidiaries'
         business as conducted or proposed to be conducted.

                            (c) None of the employees who provide services to
         the Company or its Subsidiaries are covered by collective bargaining
         agreements and, to the Seller's knowledge, there are no union or labor
         organization efforts respecting such employees.

                            (d) Neither the Company nor any of its Subsidiaries
         will have any liability to any person for compensation pursuant to
         employment or termination of employment as a result of consummating the
         transactions contemplated by this Agreement.

                  Section 2.19 Insurance.

                            (a) Schedule 2.19 sets forth a true and complete
         list of all policies of property and casualty insurance, including
         crime insurance, liability and casualty insurance, property insurance,
         business interruption insurance, workers' compensation, excess or
         umbrella liability insurance and any other type of property and
         casualty insurance insuring the properties, assets, employees and/or
         operations of the Company or its Subsidiaries (collectively, the
         "Policies"). Upon request, the Seller will make available to the Buyer
         certificates of insurance and insurance summaries from the insurance
         broker evidencing the existence of




                                       18
<PAGE>

         the Policies. Except as set forth on Schedule 2.19, all such polices
         are in full force and effect. All premiums payable under such Policies
         have been paid in a timely manner and the Seller, the Seller's
         affiliates, the Company and the Company's Subsidiaries have complied
         fully with the terms and conditions of all such Policies.

                            (b) Neither the Company nor any of its Subsidiaries
         is in default under any provisions of the Policies, and there is no
         claim by the Seller, the Seller's affiliates, the Company or any
         Subsidiary of the Company or any other person pending under any of the
         Policies as to which coverage has been questioned, denied or disputed
         by the underwriters or issuers of such Policies. Except as set forth on
         Schedule 2.19, none of the Seller, the Seller's affiliates, the Company
         or any Subsidiary of the Company has received written notice from an
         insurance carrier issuing any Policies that alteration of any equipment
         or any improvements located on Real Property, purchase of additional
         equipment, or modification of any of the methods of doing business of
         the Company or its Subsidiaries, will be required or suggested after
         the date hereof.

                  Section 2.20 Transactions with Directors, Officers and
Affiliates. Except as set forth on Schedule 2.20 and for intercompany
transactions in the ordinary course of business, since December 31, 2001, there
have been no transactions between the Company or its Subsidiaries and any
director, officer, employee, stockholder, member or other "affiliate" (as such
term is defined in Rule 405 under the Securities Act of 1933, as amended (the
"Securities Act")) of the Company, or any Subsidiary or the Seller, including,
without limitation, loans, guarantees or pledges to, by or for the Company or
Subsidiary from, to, by or for any of such persons. Except as set forth on
Schedule 2.11(d), neither the Seller nor any of their "affiliates" (as such term
is defined in Rule 405 under the Securities Act) (other than the Company or any
Subsidiary) owns or has any rights in or to any of the assets, properties or
rights used by the Company or its Subsidiaries in the ordinary course of their
business.

         with all applicable Environmental Laws, and have been in material
         compliance with Environmental Laws and, in the case of pipeline safety,
         prudent industry practices, except for non-compliance that would not
         reasonably be expected to result in the Company or its Subsidiaries
         incurring material liabilities under applicable Environmental Laws;

                                    (ii) none of the Seller, the Company or its
         Subsidiaries has received any written request for information, or has
         been notified that it is a potentially responsible party, under CERCLA
         (as hereinafter defined) or any similar state law with respect to any

         suits, proceedings or investigations pending or to their knowledge

         their compliance with any Environmental Law, or (B) the release,
         disposal, discharge, spill, treatment, storage or recycling of

                                    (iv) the Company and its Subsidiaries have
         obtained, currently maintain and are in material compliance with all
         material licenses which are required under Environmental Laws for the

         appeal nor any other action is pending to revoke any such material
         Environmental Permit;

                  Section 4.3 Employee Matters.

                            (a) The Buyer may offer to employ such Business
         Employees under such terms and conditions as the Buyer may determine,
         in its sole discretion, subject, however, to the terms and provisions
         of this Section 4.3. All Business Employees that accept the Buyer's
         offer of employment shall become the Buyer's employees as of the
         Transfer Date and all such Business Employees are hereinafter referred
         to as the "Transferred Employees." The "Transfer Date" for all
         Transferred Employees shall be the date upon which the Transition
         Services Agreement terminates pursuant to its terms.

                            (b) Transferred Employees shall be eligible to
         participate in employee benefit plans and programs of the Buyer on the
         same basis as other similarly situated employees of the Buyer.

                            (c) Each Transferred Employee shall, without
         duplication of benefits, be given credit for all service with the
         Sellers prior to the Transfer Date, using the same methodology used by
         the Sellers as of immediately prior to the Transfer Date for crediting
         service and determining levels of benefits under all employee benefit
         plans, programs and arrangements maintained by or contributed to by the
         Buyer or its affiliates (including, without limitation, the Company) in
         which the Transferred Employees become participants for purposes of
         eligibility to participate and vesting.

                            (d) The Buyer will, or will cause the Company to,
         (i) waive all limitations as to preexisting conditions exclusions and
         waiting periods with respect to participation and coverage requirements
         applicable to the Transferred Employees under any welfare benefit plans
         that such employees may be eligible to participate in after the
         Transfer Date, other than limitations or waiting periods that are
         already in effect with respect to such employees and that have not been
         satisfied as of the Transfer Date under any welfare plan maintained for
         the Transferred Employees immediately prior to the Transfer Date, and
         (ii) provide each Transferred Employee with credit for any co-payments
         and deductibles paid prior to the Transfer Date in satisfying any
         applicable deductible or out-of-pocket requirements under any welfare
         plans that such employees are eligible to participate in after the
         Transfer Date.

                            (e) Effective as of the Transfer Date, Transferred
         Employees shall become fully vested in their accrued benefits under the
         401(k) plan maintained by the Seller on behalf of such Transferred
         Employees (the



                                       24
<PAGE>

         "Seller Savings Plan") and distributions of such account balances shall
         be made available to such Transferred Employees as soon as reasonably
         practicable following the Transfer Date, in accordance with, the
         provisions of the Seller Savings Plan and applicable law. Thereafter,
         the Buyer shall accept rollover contributions from the Seller Savings
         Plan into a defined contribution or 401(k) plan maintained by the Buyer
         (the "Buyer Savings Plan") in accordance with the terms of such plan of
         the account balances distributed to the Transferred Employees from the
         Seller Savings Plan.

                            (f) The Buyer and the Seller shall cooperate as
         necessary to effectuate the provisions of this Section 4.3, including
         such steps as may reasonably be required to ensure an orderly
         transition of benefits coverage with respect to the Transferred
         Employees from the Seller Plans to the Buyer's plans.

                            (g) Each Transferred Employee shall, without
         duplication of benefits, be given credit for all accrued but unused
         paid-time-off under the Seller's paid-time-off program as of the
         Transfer Date, using the same methodology used by the Seller
         immediately prior to the Transfer Date for crediting service and
         determining the amount of such paid-time-off benefits.

                            (h) Except as specifically provided in this Section
         4.3, the Buyer and its affiliates (including the Company and its
         Subsidiaries) are not assuming any liability or obligations of the
         Seller or its affiliates with respect to any employee or former
         employee of the Seller or any of its affiliates with respect to any
         Seller Plans.

                  Section 4.4 Reserved.

                  Section 4.5 Further Assurances. Upon the request of the Buyer
at any time after the Closing Date, the Seller will promptly execute and deliver
such further instruments of assignment, transfer, conveyance, endorsement,
direction or authorization and other documents as the requesting party or
parties or its or their counsel may reasonably request in order to perfect title
of the Buyer and its successors and assigns to the Subject Membership Interest
or otherwise to effectuate the purposes of this Agreement. If it is determined
following the Closing that record and/or beneficial title to any of the Assets,
are not held by the Company or its Subsidiaries but rather is held by Seller or
any of its affiliates, Seller agrees to and to cause its affiliates to execute
such documents, agreements and instruments and take such action as may be
reasonably required to cause such title to be effectively transferred and
conveyed from Seller or its affiliates to the Company or its Subsidiaries free
and clear of any Encumbrances.

                  Section 4.9 Non-Solicitation of Employees. During the period
commencing on the date of this Agreement and ending on the second anniversary of
the Closing Date hereunder, neither the Seller nor any affiliate thereof shall
for themselves or on behalf of or in conjunction with any person, directly or
indirectly, solicit, endeavor to entice away from the Buyer or its affiliates
(including the Company or its Subsidiaries), or otherwise directly or indirectly
interfere with the relationship of the Buyer or its affiliates (including the
Company or its Subsidiaries) with any person who, to the knowledge of the
Seller, is employed by the Buyer or its affiliates (including the Company or its
Subsidiaries) and, directly or indirectly, involved with the business or
operations of the Company and its Subsidiaries; provided, however, neither the
Seller nor any affiliates thereof shall be precluded from soliciting or hiring
any such employee:

                            (a) who initiates discussions regarding such
         employment without any direct or indirect solicitation by the Seller or
         its affiliates;

                            (b) whose employment with the Company or its
         Subsidiaries has been terminated prior to commencement of employment
         with the Seller or its affiliates; or

                            (c) who responds to a general solicitation of
         employment not specifically addressed to such employees.

         Notwithstanding the foregoing, the Seller may continue to employ each
Business Employee until such time as such Business Employee becomes a
Transferred Employee.

                  Section 4.10 Reserved.

                  Section 4.11 Tax Covenants.

                            (a) Except to the extent such Taxes are reflected in
         the Final Working Capital Statement, the Seller shall be liable for,
         and shall indemnify and hold the Buyer and its affiliates harmless from
         (i) all liability for Taxes of each of the Company, its Subsidiaries
         and any predecessors thereto (including MAPCO) for all taxable periods
         ending on or before the Closing Date; (ii) the portion, determined as
         described below, of any Taxes which are incurred by the Company, its
         Subsidiaries or any predecessors thereto (including MAPCO) for any
         taxable period which begins before and ends after the Closing Date (a
         "Straddle Period") which is allocable to the portion of the Straddle
         Period occurring on or before the Closing Date (the "Pre-Closing
         Period"); (iii) all liability imposed upon the Company or any of its
         Subsidiaries on account of the inclusion of the Company, its
         Subsidiaries or any predecessors thereto (including MAPCO) in a
         consolidated, combined, unitary or similar group, for any period or
         portion of a period prior to Closing and (iv) any Taxes resulting from
         the Contributions. The portion of the Taxes for a Straddle Period which
         are allocable to a Pre-Closing Period shall be determined, in the case
         of property, ad valorem or franchise Taxes (which are not measured by,
         or based upon, net income), on a per



                                       26
<PAGE>

         diem basis and, in the case of other Taxes, by assuming that the
         Pre-Closing Period is a separate taxable period and by taking into
         account the taxable events during such period.

                            (b) The Seller shall prepare and timely file (or
         cause to be prepared and timely filed), on a basis consistent with
         prior Tax Returns, all Tax Returns with the appropriate Federal, state,
         local and foreign governmental agencies relating to the Company, its
         Subsidiaries and any predecessors thereto (including MAPCO) for taxable
         periods ending on or prior to the Closing Date and shall timely pay all
         Taxes required to be paid with respect to such Tax Returns. The Buyer
         shall prepare and timely file (or cause to be prepared and timely
         filed), on a basis consistent with prior Tax Returns, all Tax Returns
         for Straddle Periods required to be filed by the Company or any of its
         Subsidiaries and shall timely pay all Taxes required to be paid with
         respect to such Straddle Tax Returns, provided, however, that the
         Sellers shall promptly reimburse the Buyer for the portion of such Tax
         that relates to the Pre-Closing Period. The Seller shall furnish to the
         Buyer all information and records reasonably requested by the Buyer for
         use in preparation of any Tax Returns. The Buyer and the Seller agree
         to cause the Company and each of its Subsidiaries after the Closing
         Date to file all Tax Returns for any Straddle Period on the basis that
         the relevant taxable period ended as of the close of business on the
         Closing Date, to the extent permitted by applicable law. The Seller's
         covenants in respect of responsibility for Taxes as set forth above in
         this Section 4.11(b) are in no way intended to be duplicative of the
         adjustments reflected in the Purchase Price pursuant to Section 1.6.

                            (c) The Seller shall cause any tax sharing agreement
         or similar arrangement with respect to Taxes involving the Company, its
         Subsidiaries or any predecessors thereto (including MAPCO) to be
         terminated on or before the Closing, to the extent any such agreement
         or arrangement relates to the Company or its Subsidiaries or any
         predecessors thereto (including MAPCO), and after the Closing Date
         neither the Company nor any of its Subsidiaries shall have any
         obligation to make any payment under any such agreement or arrangement.

                            (d) Notwithstanding anything to the contrary in this
         Section 4.11, all excise, sales, use, transfer (including real property
         transfer or gains), stamp, documentary, filing, recordation and other
         similar taxes, together with any interest, additions or penalties with
         respect thereto and any interest in respect of such additions or
         penalties, resulting directly from the transactions contemplated by
         this Agreement (the "Transfer Taxes"), shall be borne by the party on
         which such Transfer Taxes are imposed by applicable law.
         Notwithstanding anything to the contrary in this Section 4.11, any Tax
         Returns that must be filed in connection with Transfer Taxes shall be
         prepared and filed when due by the party primarily or customarily
         responsible under the applicable local law for filing such Tax Returns,
         and such party shall use reasonable commercial efforts to provide such
         Tax Returns to the other party at least 10 days



                                       27
<PAGE>

         prior to the due date for such Tax Returns.

                            (e) WNGL will cause the MAPL Conversion and the
         Excluded Subsidiaries Distribution to be treated for Federal income tax
         purposes as distributions of the assets and liabilities of MAPCO to
         WNGL pursuant to Section 332 of the Code. The parties agree to treat
         the purchase of the Subject Membership Interest hereunder for Federal
         income tax purposes as a purchase by the Buyer from the Seller of an
         undivided 98% interest in the assets and liabilities of the Company and
         the Subsidiaries (other than the membership interests in the
         Subsidiaries) followed immediately by a contribution by the Buyer and
         the Seller to the Company of their respective undivided 98% and 2%
         interests in such assets and liabilities. The parties agree to treat
         the amount paid by the Buyer to Prudential pursuant to Section 1.4(b)
         for income Tax purposes as additional consideration paid by the Buyer
         to the Seller for such assets.

                            (f) The Buyer and the Seller shall cooperate in good
         faith to agree within 90 days after the Closing to an allocation of the
         Purchase Price and the amount paid pursuant to Section 1.4(b), any
         assumed liabilities and any other relevant items among the assets of
         the Company and its Subsidiaries, in accordance with Section 1060 of
         the Code and Treasury Regulations thereunder and any similar provisions
         of state, local, or foreign law. The Seller and the Buyer agree to

         detail the facts and circumstances with respect to the subject matter
         of such claim or action on or prior to the date on which the

         ceases to survive as set forth in Section 8.1 (it being agreed and
         understood that if a claim for a breach of a representation or warranty
         is timely made, the representation or warranty shall survive until the
         date on which such claim is finally liquidated or otherwise resolved),
         or (B) against the Buyer for breach or inaccuracy of any representation
         or breach of a warranty, unless written notice of such claim or action
         is received by the Buyer describing in reasonable detail the facts and
         circumstances with respect to the subject matter of such claim or
         action on or prior to the date on which the representation or warranty

                            (d) Notwithstanding anything in this Agreement to
         the contrary (including, without limitation, the provisions of Section
         8.2(c)(i) and (ii)), Seller hereby indemnifies and agrees to defend,

         Seller or any affiliate of the Seller.

<PAGE>

Indemnifying Party shall not relieve the Indemnifying Party of any liability
that it may have to any Indemnified Party, except to the extent that the
Indemnifying Party demonstrates that it has been materially prejudiced by the
Indemnified Party's failure to give such notice, in which case the Indemnifying
Party shall be relieved from its obligations hereunder to the extent and only to
the extent of such material prejudice. The Indemnifying Party shall defend,
contest or otherwise protect the Indemnified Party against any such claim or
action by counsel of the Indemnifying Party's choice at its sole cost and
expense; provided, however, that the Indemnifying Party shall not make any
settlement or compromise without the prior written consent of the Indemnified
Party (which consent shall not be unreasonably withheld or delayed) unless the
sole relief provided is monetary damages that are paid in full by the
Indemnifying Party. The Indemnified Party shall have the right, but not the
obligation, to participate at its own expense in the defense thereof by counsel
of the Indemnified Party's choice and shall in any event use its reasonable best
efforts to cooperate with and assist the Indemnifying Party. If the Indemnifying
Party fails timely to defend, contest or otherwise protect against such suit,
action, investigation, claim or proceeding, the Indemnified Party shall have the
right to do so, including, without limitation, the right to make any compromise
or settlement thereof, and the Indemnified Party shall be entitled to recover
the entire cost thereof from the Indemnifying Party, including, without
limitation, reasonable attorneys' fees, disbursements and amounts paid as the
result of such suit, action, investigation, claim or proceeding.

equitable relief, from and after the Closing the sole remedy of a party in
connection with (i) a breach or inaccuracy of the representations, or breach of
warranties, in this Agreement or any certificates or other documents delivered

or observe any term, provision, covenant, or agreement on the part of such party
to be performed or observed under this Agreement, shall, in each case, be as set
forth in this Article VIII.
