Item 2.  Acquisition or Disposition of Significant Amount of Assets.

         On September 10, 1996, MAPCO Inc. (the "Company" or the
"Registrant") completed the disposition of the stock of its former subsidiary
companies, MAPCO Coal Inc. and MC Mining Inc. and their respective subsidiaries
(the "Coal segment").  The Company executed  a Stock Purchase Agreement dated
as of June 28, 1996 with The Beacon Group Energy Investment Fund., L.P., a
Delaware limited partnership; MPC Partners, L.P., a Delaware limited
partnership and Alliance Coal Corporation, a Delaware corporation (hereinafter,
collectively, "Beacon") (the "Stock Purchase Agreement").  The Company signed a
letter of intent with Beacon in January of 1996, which was previously reported
on Form 8-K filed with the Securities and Exchange Commission on January 17,
1996.

         The Company sold the Coal segment for approximately
$250,000,000 in cash based upon the fair market value of the assets included.
The cash payment was financed by Beacon through loans from Chase Manhattan
Bank, N.A.

         The assets acquired through the stock purchase include one
surface and six underground mining complexes located in Kentucky, Maryland,
Illinois and Virginia, as well as a coal terminal on the Ohio River near Mt.
Vernon, Indiana, used for the transloading of coal.

Item 7.  Financial Statements, Pro Forma Financial Information and Exhibits.

         (a)      Pro Forma Financial Information.

     Unaudited Pro Forma Combined Financial Statements:

         Balance Sheet as of June 30, 1996
         Statement of Income for the Six Months Ended June 30, 1996.
         Statement of Income for the Year Ended December 31, 1995.

         The unaudited pro forma balance sheet reflects the use of the
cash proceeds, net of expenses, as a reduction of variable rate debt and the
reclassification of income taxes from being deferred to being currently
payable.
<PAGE>   3
         The unaudited pro forma income statements reflect: the
elimination of the revenues and expenses of the Coal Segment sold including the
impairment allowance related thereto; the reduction in interest expense
resulting from the application of the proceeds from the sale; the annual fee
MAPCO will receive from the buyer of the Coal Segment; and the effect of the
sale of the Coal Segment and resulting adjustment on income tax expense of
MAPCO.

         (b)      Exhibits.

                  2.      Stock Purchase Agreement dated as of June 28,
                          1996 among MAPCO Inc., a Delaware
                          corporation, The Beacon Group Energy
                          Investment Fund, L.P., a Delaware limited
                          partnership, MPC Partners, L.P., a Delaware
                          limited partnership and Alliance Coal
                          Corporation, a Delaware corporation.*

Adjustment Statement shows an excess (shortfall) of the sum of (A), (B) and (C)
over (from) the targets for (A), (B) and (C) set forth in Section 1.5(b)(v),
then at the Closing, NewCo shall pay to MAPCO the amount of such excess over
$1,000,000 together with simple interest thereon at the rate of 9.5% from and
including August 1, 1996 to but not including the Closing Date, or MAPCO shall
credit against the amount payable at Closing by NewCo the amount of such
shortfall over $1,000,000 together with simple interest thereon at the rate of
9.5% from and including August 1, 1996 to but not including the Closing Date,
as the case may be. Any such payment or credit, together with the interest
thereon, shall be deemed to be an adjustment to the Purchase Price paid by
NewCo to MAPCO pursuant to Section 1.2, and shall be accounted for in
determining the amount of any final adjustment to the Purchase Price as
contemplated by Section 1.5(d).

                                   ARTICLE II

MAPCO, enforceable against MAPCO in accordance with their respective terms.

                 Section 2.2      No Conflicts, etc. Except as set forth in
Schedule 2.2:

of the transactions contemplated hereby and thereby will not result in (i) any
conflict with the charter documents or by-laws of MAPCO, MCI, MCMI or any of
the Coal Subs, or (ii) any material breach or violation of or default under, or
result in the creation or imposition of any liens, mortgages, security

promulgated thereunder (the "HSR Act") and (ii) filings, consents or approvals
which, if not made or obtained prior to Closing are not, individually or in the
aggregate, reasonably expected to have a Material Adverse Effect (as defined
below in Section 8.6).

                 Section 2.3      Corporate Status and Authority of MCI, MCMI
and the Coal Subs. Each of MCI, MCMI and the Coal Subs (i) is a corporation

                 Section 2.4      Ownership of MCI, MCMI and the Coal Subs.
With respect to the Shares and the capital stock issued by the Coal Subs (a)

capital stock have been duly authorized, validly issued and are fully paid and
nonassessable. There are no outstanding options, warrants, conversion or other
rights or agreements of any kind (except as contemplated hereby) for the
purchase or acquisition from, or the sale or issuance by, MAPCO, MCI, MCMI or

                          (b)     The Annual Financial Statements have been

                 Section 2.7      Absence of Undisclosed Liabilities. Except as
set forth on Schedule 2.7 or as disclosed in the other Schedules delivered
hereunder, to the knowledge of MAPCO, MCI, MCMI and the Coal Subs, there are no

Annual Financial Statements or disclosed in the notes thereto, and (c) contract
liabilities that, if incurred after the date hereof, would not result in a
breach of the covenants set forth in Section 5.2(a)(xii). For purposes of this
Section 2.7 only, a liability shall be material if it is (i) reasonably
expected to exceed $100,000 or (ii) related to another liability by virtue of
arising from the same facts and circumstances, and taken together with each
other such related liability is reasonably expected to exceed $100,000.

intended to be used for active mine openings when operations commence), air
shafts, mine slopes, coal preparation and processing plants, slurry and refuse
disposal areas, product silos and stockpile areas, electrical power substations
owned by MCI, MCMI or the Coal Subs, rail load outs, coal loading facilities,

subsurface support facilities associated therewith ("Operating





                                       9
<PAGE>   19
Facility Properties"); and (iv) all other material lands and interests in land
owned, leased, subleased or otherwise controlled by MCI, MCMI or the Coal Subs

Gibson County, Indiana, during the five year period beginning when mining
operations are to commence), as depicted on mine engineering map projections or
plans described on Schedule 2.8(b), copies of which have been provided to
Beacon Investors or their representatives; provided, however, that the "Five

on Schedule 2.8(b), a copy of which has been provided to Beacon Investors or
their representatives.

                          (c)     (i)  Except as set forth in Schedule 2.8(a),
each of MCI, MCMI and the Coal Subs, as applicable, (x) has good and marketable
title to the Operating Facility Properties owned by MCI, MCMI or the Coal Subs,
free and clear of Liens other than Permitted Encumbrances, and (y) with respect
to those Operating Facility Properties leased, subleased or otherwise
controlled by MCI, MCMI or the Coal Subs, has good and marketable leasehold or
other title to same assuming that the lessor granting such leasehold interest
also has good and marketable title to, or a good and marketable leasehold
interest in, the applicable Operating Facility Property, free and clear of
Liens other than Permitted Encumbrances, and the lease, sublease or other
instrument pursuant to which such Operating Facility Property is held permits
the present and intended use or operation of the facility located thereon for a
period co-existent with MCI's, MCMI's or the Coal Sub's present and anticipated
need for such facilities subject to the terms, conditions, provisions and
limitations in such instruments.

                                  (ii)  Except as set forth in Schedule 2.8(a),

                          (d)  For purposes of this Agreement, the term
"Merchantable Title" shall mean, with respect to any Real Property Interest,
and subject to the terms, conditions, provisions and conditions contained in
the Realty Deeds and Leases (defined below) creating such Real Property
Interest, the ownership, rights, possession and title in the jurisdiction and
locale where the Real Property Interest is located which, is in each case
legally sufficient in all material respects to mine, remove, process and
transport coal by the mining methods currently utilized or contemplated by the
Five Year Plan applicable to the mining complex where the Real Property
Interest is located, excepting the "Permitted Encumbrances" (defined below) and
such title defects, imperfections, limitations, correlative rights, or
appurtenant rights or obligations contained in, arising from or created by the
instrument under which MCI, MCMI or the Coal Subs hold title to said Real
Property Interest, or contained in its chain of title thereto, which do not
materially and adversely affect current or intended use or operation of the
subject Real Property Interest as contemplated by the applicable Five Year Plan
or which are capable of being routinely addressed, cured, avoided or assumed in
the ordinary course of business and land management of MCI, MCMI or the Coal
Subs. For purposes of this Section 2.8, a title defect, imperfection or
limitation shall be deemed capable of being cured in the ordinary course of
business if the particular issue may be resolved at an expense of less than

with the current or intended use of the Real Property Interest(s) affected by
the easement or right-of-way in the execution of the Five Year Plan; provided,
however, electric power transmission lines and/or natural gas pipelines, and
easements associated therewith, which may require relocation at the MCMI No. 1
Mine, Pontiki Mine, the Martiki Mine and/or the Toptiki Mine, and
outconveyances of lands or interests in lands to utility companies to permit
the construction and installation of electric power substations and other
facilities necessary or desirable for current or future operation of the mines
or supporting facilities, shall be deemed Permitted Encumbrances regardless of
whether they, or any of them, may materially and adversely affect the current
or intended use of the Real Property Interests or mining or other operations
contemplated by the Five Year Plan(s); (ii) liens to secure the payment of real
estate taxes not yet due and payable or which are being contested in good faith
by appropriate proceedings; (iii) landlord's liens and statutory liens for
mechanics, materialmen or laborers for work and labor delivered to or performed
on the premises securing obligations of MCI, MCMI or the Coal Subs or their
contractors incurred in the ordinary course of business; (iv) specific
encumbrances and exceptions noted in Schedule 2.8(a); (v) conditions,
encumbrances and covenants of record and title exceptions, reservations,
limitations, defects and





                                       11

2.8(a), to the knowledge of MCI, MCMI and the Coal Subs, no material adverse
claims or disputes currently exist or have been threatened or asserted with
regard to the Real Property Interests which are reasonably expected to have a
material adverse effect upon the right, title or interest of MCI, MCMI or the
Coal Subs to the Real Property Interests or upon continuing mining operations
in the ordinary course of business at the affected mining complex as
contemplated by the applicable Five Year Plan.

                                  (ii)     True and complete copies of each
deed, lease, sublease, surface agreement, easement, reservation, wheelage
agreement and other agreements or instruments pursuant to which any of MCI,
MCMI or the Coal Subs acquired or leased the Real Property Interests, or
conveyed, subleased or otherwise granted to others any interest therein, (the
"Realty Deeds and Leases"), together with copies of any title opinions,
abstracts, surveys and appraisals in the possession of MCI, MCMI or the Coal
Subs or the law firm of Bowles, Rice, McDavid, Graff, Love & Getty and any
policies of title insurance currently in effect with respect to the Real
Property Interests have been made available to the Beacon Investors or their
representatives; provided, however, MAPCO makes no representation or warranty
as to the accuracy or completeness of any of said title opinions, abstracts,
surveys or appraisals.

                                  (iii)    Except as set forth in Schedule
2.8(a), each of the Realty Deeds and Leases is valid and enforceable against
MCI, MCMI and/or the Coal Subs, as applicable, and to the knowledge of MAPCO,
MCI, MCMI and the Coal Subs, each of the other parties thereto, is in full
force and effect, and none of MCI, MCMI and the Coal Subs is in material
default in the payment or performance or observance of any term, provision,
covenant or condition of the Realty Deeds and Leases to which any of them is a
party or by which any of them or their respective properties or assets may be
bound, nor are MAPCO, MCI, MCMI or the Coal Subs aware of facts or other
circumstances which with notice and passage of time would constitute a default,
except for such default or defaults as are not, individually or in the
aggregate, reasonably expected to have a material adverse effect on the
operation or use of any Operating Facility Property, or as contemplated by the
applicable Five Year Plan(s), upon the Operating Property or Active Operating
Reserve or future use of a Non-Operating Property in connection with the
Business.

                                  (iv)     Neither the whole or any part of a
Real Property Interest is subject to any pending suit for condemnation or other
taking by a public





                                       12

authority, and to their knowledge, no such condemnation or other taking is
threatened or contemplated.

                                  (v)      Except as set forth in Schedule
2.8(a), none of MCI, MCMI or the Coal Subs have wilfully and/or intentionally

notice of any claim asserting a wilful and/or intentional trespass on the land
or interests in land of a third party in connection with the operation of the
Business.

                                  (vi)     Schedule 2.8(a) discloses those
material Real Property Interests not yet owned, leased, subleased or otherwise
controlled by MCI, MCMI or the Coal Subs which are included on the tract maps
for each mine as described on Schedule 2.8(a), and which are anticipated to be
mined as contemplated by the current Five Year Plans. The tract maps for each
mine as described on Schedule 2.8(a) indicate those material Real Property
Interests not yet owned, leased or subleased or otherwise controlled by MCI,
MCMI or the Coal Subs and which are currently anticipated by MAPCO, MCI, MCMI
or the Coal Subs to be mined within the five-year period subsequent to the
applicable Five Year Plan. Except as set forth in Schedule 2.8(a), MAPCO, MCI,
MCMI and the Coal Subs are not aware of any fact or circumstance which would
prevent MCI, MCMI or the Coal Subs from acquiring the rights necessary to mine,
use or operate those properties anticipated to be mined as contemplated by the
current Five Year Plans, or currently anticipated by MAPCO, MCI, MCMI or the
Coal Subs to be mined within the five-year period subsequent to the applicable
Five Year Plan, on then customary terms and conditions, consistent with
industry norms for the applicable geographic region, and MCI's, MCMI's and the
Coal Subs' past experience.

                                  (vii)    Except as set forth in Schedule
2.8(a) or for Permitted Encumbrances, none of MCI, MCMI or the Coal Subs have
encumbered its Real Property Interests and each of MCI and the Coal Subs has,
or subject to the limitations and conditions set forth in the last sentence of
Section 2.8(f) (vi) above and Schedule 2.8(a), will be able to acquire Real
Property Interests necessary to execute the applicable Five Year Plans.

                          (g)     Personal Property. All equipment, machinery,
motor vehicles, furniture, supplies and other tangible personal property used
by each of MCI, MCMI and the Coal Subs (the "Personal Property"), is in
satisfactory working condition (normal wear and tear excepted) and suitable in
all material respects for the purposes for which it is currently being used,
except for such items of Personal Property currently being repaired or rebuilt,
or not currently in use and not intended to be returned to service. Except as
set forth in Schedule 2.8(g), each of MCI, MCMI or a Coal Sub, as the case may
be, has good and valid title to the Personal Property owned by it and good and
valid leasehold interests in all Personal Property leased by it, in each case
free and clear of any and all Liens other than Permitted Liens. True





                                       13

governmental charges not yet due or which are being contested in good faith and
by appropriate proceedings identified on Schedule 2.14(e), (b) statutory Liens

obligations, (d) Liens reflected in the Annual Financial Statements (defined
above), (e) Liens set forth on Schedule 2.8(a), (f) Liens arising from this
Agreement or any of the transactions contemplated hereby, and (g) Liens which
do not detract from the value or interfere with the current use, and the use
presently planned by MAPCO and its subsidiaries, of the assets and properties
of the Business in any material respect.

                          (h)  Intellectual Property. To the knowledge of
MAPCO, MCI, MCMI and the Coal Subs, the Business is not currently infringing
upon the intellectual property rights of any third party.

                          (i)     Mining Data. MAPCO has provided the Beacon
Investors and John T. Boyd Company ("Boyd") with access to all requested
material geological data, reserve data, mine maps, core hole logs and
associated data, coal measurements, coal samples, lithologic data, coal reserve
calculations or reports, washability analyses or reports, mine plans, mining
permit applications and supporting data, engineering studies and all other
information, maps, reports and data in the possession of MAPCO relating to or
affecting MCI's, MCMI's or the Coal Subs' coal reserves, coal ownership, coal
leases (whether any Coal Sub is a lessee, lessor, sublessee or sublessor),
mining conditions, mines and mining plans utilized by the Coal Subs in the
ordinary course of operations (collectively, the "Mining Data"). To the
knowledge of MAPCO, MCI, MCMI and the Coal Subs, the Mining Data provided to
Boyd and the Beacon Investors was as of its date free from any material
inaccuracies, taking into account any item of Mining Data that was corrected by
any other item of Mining Data dated subsequent thereto. Each of MAPCO, MCI,
MCMI and the Coal Subs have reviewed the final report delivered by Boyd dated
June 1996 (the "Boyd Report") prior to the Closing and referred to in Section
8.4(g) with respect to MCI's, MCMI's, or the Coal Subs' coal reserves
(including quantity and quality), coal ownership, coal leases (whether any Coal
Sub is a lessee, lessor, sublessee or sublessor), mining conditions, mines and
mining plans, and to the knowledge of each of MAPCO, MCI, MCMI and the Coal
Subs, the Boyd Report, including the conclusions therein, are free of any
material inaccuracies.

contracts and commitments of the following types to which MCI, MCMI or any of
the Coal Subs is a party and which are maintained or entered into for the
benefit of the employees of MCI, MCMI or any of the Coal Subs, including such
of MAPCO's plans for its employees in which employees of MCI, MCMI or any of
the Coal Subs participate:  (i) employment and consulting agreements (including
severance, retention and termination agreements); (ii) collective bargaining
agreements or memoranda of understanding; and (iii) profit sharing, pension,

                          (b)     Remuneration. Schedule 2.11(b) lists each
employee of MCI, MCMI or any of the Coal Subs whose current annual base salary
rate exceeds $125,000, together with such base salary rate for each such
employee.

                          (c)     ERISA. All employee benefit plans that are
required to be disclosed on Schedule 2.11(a) and are subject to the Employee
Retirement Income Security Act of 1974, as amended ("ERISA") (the "Plans")
comply in all respects and have been established, operated and administered in
accordance with their terms and the requirements of ERISA and the Internal
Revenue Code of 1986, as amended (the "Code"), except for any failures to
comply that are not, individually and in the aggregate, reasonably expected to
have a Material Adverse Effect. Each plan, program, arrangement, agreement,
contract or commitment which is required to be disclosed on Schedule 2.11(a)
and which is not a Plan (a "Benefit Arrangement") complies in all respects and
has been established, operated and administered in accordance with its terms
and the requirements of applicable law, except for any failures to comply that
are not, individually and in the aggregate, reasonably expected to have a
Material Adverse Effect. No material liability (other than for annual premiums)
to the Pension Benefit Guaranty Corporation has been, or is reasonably expected
to be, incurred by MCI, MCMI or any of the Coal Subs with respect to any Plan
or any other employee benefit plan which is maintained or contributed to by
MAPCO or by any member of the same controlled group of corporations as MAPCO
(an "ERISA Affiliate") within the meaning of section 4001(a)(3) of ERISA and
which is subject to Title IV of ERISA. None of MCI, MCMI or any of the Coal
Subs has incurred any material liability for any tax or penalty imposed by
section 4975 of the Code or section 502(i) of ERISA with respect to any Plan.
Except as described in Schedule 2.11(c), none of MCI, MCMI, any of the Coal
Subs, MAPCO or any ERISA Affiliate has withdrawn at any time within the
preceding six years from any multiemployer plan, as defined in section 3(37) of
ERISA, except for any such withdrawals which did not result in any material
withdrawal liability to MCI, MCMI, any Coal Sub, MAPCO or any ERISA Affiliate





                                       17

behalf of any Plan or by any employee involving any Plan or Benefit Arrangement
(other than routine claims for benefits). Except as described in Schedule
2.11(c), all material contributions required to have been made by MCI, MCMI or
any of the Coal Subs to any Plan or under any Benefit Arrangement have been
made timely. There does not exist any accumulated funding deficiency within the
meaning of either Section 412 of the Code or Section 302 of ERISA as to any
Plan or any other employee benefit plan which is maintained or contributed to
by MAPCO or any ERISA Affiliate. Each Plan which is intended to qualify under
Section 401(a) of the Code has received a determination letter concluding that
such Plan so qualifies, and no amendment has been adopted or action has been
taken by MAPCO, MCI, MCMI or any Coal Sub that, to the knowledge of MAPCO,
would cause such Plan to lose its qualified status.  Except as set forth in
Schedule 2.11(c) and as provided under any Plan, none of MAPCO, MCI, MCMI or
any Coal Sub provides post-retirement medical or life insurance benefits or
coverage to any of its current or former employees or to any dependent of any
such current or former employee, except as may be required under Section 4980B
of the Code or Section 601 of ERISA. Except as provided under any Plan or any
Benefit Arrangement, the consummation of the transactions contemplated by this
Agreement will not result in a "change of control" under any Plan or any
Benefit Arrangement and will not result in any increase in the amount of
compensation or benefits or, except as specifically provided herein, accelerate
the vesting or timing of payment of any compensation or benefits payable to or
in respect of any current or former employee of MCI, MCMI or any of the Coal
Subs or the beneficiary or dependent of any such current or former employee.
All representations and warranties in this Section 2.11(c) are made to the
knowledge of MAPCO to the extent related to any multiemployer plan.

with wage, hour and collective bargaining laws and the payment of social
security and similar taxes, and (viii) no person has asserted that MCI or any

or any taxes or penalties for failure to comply with any of the foregoing.

                          (e)     MCMI Labor Matters. Schedule 2.11(e)

operations that were initially conducted by MCMI's own employees and since
August 23, 1994, have been conducted by several independent contractors and

MAPCO, MCI, MCMI nor the Coal Subs have any knowledge or information as of the
date of this Agreement reasonably indicating that any of the above events will
be forthcoming.

                          (g)     Except as set forth in Schedule 2.16, and

MCI, MCMI and the Coal Subs, or obligations relating to workers' compensation
benefits or federal or state occupational disease benefits which may have been

not result in any material breach of or default under, or result in the
forfeiture, termination, or impairment of any material rights under any of the
contracts, agreements and commitments and Real Property Deeds and Leases listed

of any filing with, any other person.

                 (b)      After the Closing, each Permit and Permit application
will continue in full force and effect, in each case without breaching the
terms thereof or resulting in the forfeiture or impairment of any rights

granting such Permits and shall have obtained reasonable assurances that the
operations of the Business may continue unimpaired while such approvals are
pending from and after Closing.

                 Section 2.23     No Material Adverse Effect. The aggregate
effect of all inaccuracies in the representations and warranties set forth in
this Article II other than this Section 2.23, assuming for purposes of this

                                  (iii)    refrain from taking any actions
which, or fail to take any actions the omission of which, would cause any of

books and records and other information related to the Business of MCI, MCMI,
and the Coal Subs and furnish such information and documents in its or their
possession relating to MCI, MCMI, and the Coal Subs as the Beacon Investors may
reasonably request. All such information and documents obtained by the Beacon
Investors shall be subject to the terms of the Confidentiality Agreement, dated
September 18, 1995 (the "Confidentiality Agreement"), between MAPCO and the
Fund.

                 Section 5.3      Publicity. All press releases, filings and
other public announcements concerning the transactions contemplated hereby will
be subject to review and approval by each of MAPCO and the Beacon Investors,
such approval not to be unreasonably withheld. Such approval shall not be
required if the person issuing such release, filing or public announcement
reasonably believes, based on advice of counsel, that it is required by law to
do so, but in any such case, all reasonable efforts shall be made to consult
with the other party in advance of such release, filing or announcement.

                 Section 5.4      Exclusivity. Until the termination of this
Agreement pursuant to Section 9.5, MAPCO will not, directly or indirectly,
through any officer, director, agent or otherwise, initiate, maintain, solicit,
permit or encourage or respond to any other inquiries or proposals regarding,
or negotiate or discuss with any third party (including by way of furnishing
information concerning the Business), or take any other action to facilitate
any inquiries with respect to or the making of, any proposal that constitutes
or may reasonably be expected to lead to a Competing Transaction. For purposes
hereof, the term "Competing Transaction" shall mean any proposal with respect
to the acquisition of any part of or interest in the Business other than as
contemplated by this Agreement. In the event MAPCO or any of its Affiliates
receives any unsolicited proposal regarding a Competing Transaction,





                                       36
<PAGE>   46
MAPCO agrees promptly to advise the Beacon Investors of the existence and terms
of any such proposal.

                 Section 5.5      Notification of Certain Matters. MAPCO shall
give prompt notice to the Beacon Investors, and the Beacon Investors shall give
prompt notice to MAPCO, of (a) the occurrence, or non-occurrence, of any event
the occurrence or non-occurrence of which would be reasonably likely to cause
(i) any representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect or (ii) any covenant, condition or agreement
contained in this Agreement not to be complied with or satisfied in any
material respect and (b) any failure of MAPCO or the Beacon Investors, as the
case may be, to comply with or satisfy any covenant, condition or agreement to
be complied with or satisfied by it hereunder in any material respect;
provided, however, that the delivery of such notice pursuant to this Section
5.5 shall not limit or otherwise affect the remedies available hereunder to the
party receiving such notice.

                 Section 5.6      Insurance. MAPCO will continue to carry and
maintain or cause to be carried and maintained, in full force and effect, the
insurance policies listed on Schedule 2.18, or policies with comparable
coverage, to the Closing Date, and will reasonably assist NewCo in its efforts
to obtain insurance coverage for the business of MCI, MCMI and the Coal Subs
from and after the Closing.

                 Section 5.7      Disclosure Schedules; Updates. MAPCO, the
Beacon Investors and NewCo shall promptly review in good faith the Schedules
submitted by MCI on June 21, 1996. The Beacon Investors and NewCo shall
identify to MAPCO and MCI in writing any disagreements or concerns they may
have with respect to any items disclosed on such Schedules, and shall be deemed
to have accepted all other items disclosed thereon and not so identified.
MAPCO, the Beacon Investors and NewCo shall use all reasonable efforts to
resolve in good faith any such disagreement or concern.  No later than five
business days prior to the scheduled Closing Date, MAPCO shall amend or
supplement the Schedules with respect to any matter coming to its attention or
arising which, if known to it or existing prior to the date of this Agreement,
would have been required to be set forth therein or which is necessary or
desirable to complete or correct any information contained therein or in any
representation or warranty rendered inaccurate thereby. Notwithstanding the
foregoing, for the purposes of determining the satisfaction of the conditions
to Closing set forth in Article VIII, the Schedules shall not be deemed to have
been amended or supplemented from the form in which they were delivered on the
date of this Agreement, but if the Closing shall occur shall be deemed to have
been amended for all purposes from and after the Closing.

                 Section 5.8      Non-Competition.

                          (a)  During the period commencing on the Closing Date
and ending on the second anniversary thereof (the "Non-Compete Period"), MAPCO
shall not, and it shall cause each of its subsidiaries, Affiliates and officers
not to (i) import, market, sell, produce, distribute, provide, promote or
develop coal or coal mine properties in any manner whatsoever, on either a
wholesale or retail basis anywhere in the world (a "Competitive Business"), or
(ii) own an interest in, manage, operate, join, control or participate in or be
connected with as a partner, member, stockholder, co-venturer, consultant or
otherwise, any corporation, company, partnership, firm, association,
enterprise, or other entity that engages in a Competitive Business; provided
however that nothing in clauses (i) or (ii) of this Section 5.8(a) shall
prohibit or restrain MAPCO or any of its subsidiaries, Affiliates or officers
from (v) engaging in any of the businesses or projects contemplated by the
Indonesian Projects Agreement whether as a partial owner or direct participant
as contemplated thereby, (w) maintaining and continuing in accordance with
current and past practices of the operations of the Retiki Mine and the other
Excluded Assets and Excluded Liabilities, (x) acquiring ownership of, control
of or investing in, being acquired by or merging with, any person or entity
that, prior to such acquisition, investment or merger, was engaged in a
Competitive Business, (y) acquiring shares of capital stock, a partnership or
other entity where such shares or interest represent a minority interest of
five percent of less of such person's or entity's outstanding capital stock or
equity interests, or (z) acquiring the indebtedness of any person or entity.

                          (b)  Notwithstanding the provisions of Section
5.8(a), with respect to MAPCO, its subsidiaries, Affiliates and officers (i)
activities with respect to coal mine properties that relate to products other
than coal (e.g., coal bed methane or minerals other than coal) shall not be
considered a Competitive Business, (ii) activities that relate solely to the
transportation of coal (including coal-slurry pipelines) shall not be
considered a Competitive Business, and (iii) engaging in activities that would
constitute a Competitive Business shall not be considered a breach of this
Section 5.8 if such engagement results from any transaction contemplated by
clause (x) in Section 5.8(a).

                          (c)  The invalidity or unenforceability of any
provision of this Section 5.8, in whole or by virtue of the following sentence
in part, shall not affect the validity or enforceability of any other provision
of this Section 5.8 or of any other provision of this Agreement, all of which
shall to the full extent consistent with applicable law continue in full force
and effect. In addition, if any provision of Section 5.8 shall be adjudged to
be excessively broad as to duration, geographical scope, activity or subject,
the parties hereto intend such provision shall be deemed modified to the
minimum degree necessary to make such provision valid and enforceable under
applicable law and that such modified provision shall thereafter be enforced to
the fullest extent possible.

                 Section 5.9      Indonesian Projects Agreement. Immediately
upon the execution and delivery hereof, MAPCO, the Beacon Investors and NewCo
shall negotiate in good faith and with all deliberate speed an Indonesian
Projects Agreement containing the terms set forth in Exhibit D, which Agreement
shall be signed by the parties thereto immediately prior to or at the Closing
hereunder.

                 Section 5.10     Joint Action. For purposes of this Agreement,
the Fund shall act on behalf of the Beacon Investors, all of which shall act as
a group and not singly. MAPCO shall be entitled to rely on any consent or
approval given by the Fund as binding on the other Beacon Investors.

                 Section 5.11     Section 338(h)(10) Election. At NewCo's
option, MAPCO will join with NewCo in making an election under Section
338(h)(10) of the Code (and any corresponding elections under state, local, or
foreign tax law) (collectively, a "Section 338(h)(10 Election") with respect to
the purchase and sale of the stock of MCI and MCMI hereunder. MAPCO will pay
any Tax attributable to the making of the Section 338(h)(10) Election and will

purchase and sale of the stock of MCI and MCMI hereunder.

                 Section 5.12     Subsequent Transaction(s). If, pursuant to
any transaction or series of transactions entered into (or if agreements with
respect thereto are entered into or distributions or dividends are declared)
within eighteen months of the Closing Date pursuant to which the Beacon
Investors receive cash, cash equivalents, short term notes which are not
restricted from transfer by their terms and which are payable within one year,
or marketable securities (collectively, "Distributed Cash") from NewCo, MCI,
MCMI or the Coal Subs, or NewCo, MCI, MCMI or the Coal Subs receive proceeds
from any public offering of equity securities registered under the Securities
Act of 1933 (the "Proceeds"), and the sum of such Distributed Cash and Proceeds
exceeds the amount that would constitute a full return of the Beacon Investors'
total investment in the transaction contemplated by this Agreement plus a 40%
annually compounded return on such investment, then the Beacon Investors and/or
NewCo jointly shall pay to MAPCO 25% of the excess of such amount.

                 Section 5.13     Key Customer Visits. Immediately following

<PAGE>   49

that all such visits and interviews be completed within 25 days of the date
hereof. The Beacon Investors shall report promptly to MAPCO any concerns or
facts which they learn of during such visits and interviews which if not
remedied could lead to the failure of any condition precedent to Closing set
forth in Section 8.2 or 8.4 herein. Promptly upon completion of such visits and
interviews, the Beacon Investors shall inform MAPCO in writing, with a copy to
MCI, whether or not the condition precedent set forth in Section 8.4(g) has
been satisfied.

                          (a)     MAPCO shall have the right to file all Tax
Returns and control the audit and subsequent contest with respect to any Taxes
relating to the operation of the Business prior to and including the Closing
Date. Subject to the last sentence of Section 5.14(b), any refunds of any Taxes
relating to the operation of the Business prior to and including the Closing
Date shall be for the account of MAPCO.

                          (b)     All Taxes accrued or required to be paid by
MAPCO or any Non-Company Affiliate with respect to operations of the Business
during the period from and after July 31, 1996 through the Closing Date (the
"Interim Period") determined pursuant to this Section 5.14(b) (the "Interim
Taxes"), shall be advanced to or for the benefit of MAPCO or such Non-Company
Affiliate no sooner than three business days prior to the date on which such
Interim Taxes are required to be paid by MAPCO or such Non-Company Affiliate,
except that any Interim Taxes not advanced prior to the Closing Date shall be
advanced on the Closing Date immediately prior to the Closing. The calculation
of Interim Taxes shall be made by determining the difference between the
aggregate of MAPCO's and the Non-Company Affiliates' liability for Taxes
calculated with and without the inclusion of the results of the operation of
the Business for the Interim Period. To the extent that the aggregate of
MAPCO's and the Non-Company Affiliates' liability for Taxes is increased as a
result of such inclusion, such increase shall be the amount of Interim Taxes.
To the extent that the aggregate of MAPCO's and the Non-Company Affiliates'
liability for Taxes is reduced as a result of such inclusion, the amount of
Interim Taxes shall be zero and the amount of such reduction, together with all
prior advances to or for the benefit of MAPCO on account of Interim Taxes shall
be paid by MAPCO to NewCo. The determination of the amount of Interim Taxes
shall be made (i) during the Interim Period whenever MAPCO determines that it
may be required to pay Taxes that are interim Taxes, (ii) two days prior to the
Closing Date, and (iii) by no later than October 15, 1997 based upon any Return
in respect of Interim Taxes filed by MAPCO or a Non-Company Affiliate, which
Returns NewCo shall be entitled to examine upon request. Whenever the amount of
Interim Taxes is calculated or recalculated to be an amount that is lower or
greater than the previous determination of Interim Taxes, MAPCO shall
immediately return to NewCo





                                       40
<PAGE>   50
the amount of such reduction, or NewCo shall immediately pay to MAPCO the
amount of such increase, as the case may be.

                          (c)     NewCo, MCI, MCMI and the Coal Subs shall pay
(or shall cause their Affiliates to pay) all Taxes other than Interim Taxes
with respect to the operations of the Business for the periods beginning after
the Effective Date.

cause MCI, MCMI or one of the Coal Subs, as applicable, to honor, pay, perform
and be solely responsible for, and to indemnify and hold harmless MAPCO from
and against, and pay or reimburse MAPCO for, any and all liabilities,

<PAGE>   51
                          (c)     Notwithstanding any provision of Section
6.1(a) or 6.1(b) to the contrary, MAPCO shall assume and be solely responsible

pension plans known as the Retirement Plan for the Employees of South Atlantic
Coal Company, Inc. (the "SAC Pension Plan") and the MAPCO Inc. and Subsidiaries
Pension Plan (the "MAPCO Pension Plan"). Prior to the Closing, MAPCO shall take
all necessary and appropriate action to either (A) cause each NewCo Employee to
be fully vested under the MAPCO Pension Plan (if such NewCo Employee is a
participant in the MAPCO Pension Plan), or under the SAC Pension Plan (if such
NewCo Employee is a participant in the SAC Pension Plan), or (B) permit each
NewCo Employee to withdraw a lump sum distribution of the net present value of
their accrued benefits under the MAPCO Pension Plan or the SAC Pension Plan, as
the case may be, as





                                       42

permitted under the terms of the applicable Plan and applicable law. MAPCO
shall upon the request of NewCo and at a mutually agreeable cost to be funded

judgment or decision thereon.

                          (f)     Claim Notice. The term "Claim Notice" shall

                 Section 7.5      Notification of Claims. In no case shall any
Indemnitor under this Agreement be liable with respect to any Loss or Third
Party Claim against any Indemnitee unless the Indemnitee shall have delivered
to the Indemnitor a Claim Notice and the following conditions are satisfied:

                          (a)     Timely Delivery of Claim Notice. Except as
provided in Section 7.5(b) or 7.5(c), no right to indemnification under this
Article VII shall be available to an Indemnitee with respect to a Third Party
Claim unless the Indemnitee shall have delivered to the Indemnitor within the
Notice Period a notice describing in reasonable detail the facts giving rise to
such Third Party Claim (a "Claim Notice") and stating that the Indemnitee
intends to seek indemnification for such Third Party Claim from the Indemnitor
pursuant to this Article VII.

                          (b)     Late Delivery of Claim Notice. If, in the
case of a Third Party Claim, a Claim Notice is not given by the Indemnitee
within the Notice Period as set forth in Section 7.5(a), the Indemnitee shall
nevertheless be entitled to be indemnified under this Article VII:

                                  (i)      if the Indemnitee can establish that
the time elapsed between the end of the Notice Period and the giving of the
Claim Notice is reasonable; and

                                  (ii)     to the extent that the Indemnitee
can establish that the Indemnitor has not been prejudiced by such time elapsed.

                          (c)     Paid or Settled Claims. If a Claim Notice is
not given by the Indemnitee prior to the payment or settlement of a Third Party
Claim, the Indemnitee shall be entitled to be indemnified under this Article
VII only to the extent that the Indemnitee can establish that the Indemnitor
has not been prejudiced by such payment or settlement.

                 Section 7.6      Defense of Claims. Upon receipt of a Claim
Notice from an Indemnitee with respect to any Third Party Claim, the Indemnitor
shall have the right to assume and control the defense thereof (and any related
settlement negotiations) with counsel reasonably satisfactory to such
Indemnitee and the Indemnitee shall cooperate in all reasonable respects in
such defense. The Indemnitee shall have the right to employ separate counsel at
such Indemnitee's expense in any action or claim and to participate in the
defense thereof, provided, however, that the fees and expenses of counsel
employed by the Indemnitee shall be





                                       47
<PAGE>   57
at the expense of the Indemnitor if such counsel is retained pursuant to either
of the following two sentences or if the employment of such counsel has been
specifically authorized in writing by the Indemnitor. If the Indemnitor does
not notify the Indemnitee within sixty days after receipt of the Claim Notice
the Indemnitee shall have the right to defend the claim with counsel of its
choosing reasonably satisfactory to the Indemnitor, subject to the right of the
Indemnitor to assume the defense of any claim at any time prior to settlement
or final determination thereof. Notwithstanding anything to the contrary
contained in this Section 7.6, the Indemnitee shall have the right to employ
separate counsel if there shall be available one or more defenses or one or
more counterclaims available to the Indemnitee which conflicts with one or more
defenses or one or more counterclaims available to the Indemnitor. The
Indemnitee shall send a written notice to the Indemnitor of any proposed
settlement of any claim, which settlement the Indemnitor may reject, in its
reasonable judgment, within thirty days of receipt of such notice. Failure to
reject such notice within such thirty day period shall be deemed an acceptance
of such notice.

                 Section 7.7      Access and Cooperation. After the Closing
Date, the Beacon Investors and NewCo, on the one hand, and MAPCO, on the other
hand, shall (i) each cooperate fully with the others as to all Third Party
Claims, shall make available to the others, as reasonably requested, all
information, records and documents relating to all Third Party Claims and shall
preserve all such information, records and documents until the termination of
any Third Party Claim and (ii) make available to the others, as reasonably
requested, personnel (including technical and scientific), agents and other
representatives who are responsible for preparing or maintaining information,
records or other documents, or who may have particular knowledge with respect
to any Third Party Claim.

                 Section 7.8      Assessment of Claims. In the event that any
of the Losses for which an Indemnitor is or allegedly responsible pursuant to
Sections 7.2, 7.3 or 7.4 are recoverable or potentially recoverable against any
third party at the time when payment is due hereunder, following payment by the
Indemnitor to the Indemnitee for such Losses the Indemnitee shall assign any
and all rights that it may have to recover such Losses to the Indemnitor, or,
if such rights are not assignable under applicable law or otherwise, the
Indemnitee shall attempt in good faith to collect any and all Losses on account
thereof from such third party for the benefit of, and at the expense and
direction of, the Indemnitor. Each Indemnitee shall use reasonable efforts to
mitigate any Loss for which an Indemnitor may have an indemnification
obligation pursuant to this Article VII.

                 Section 7.9      Limits on Indemnification.

                          (a)     Procedure for Payments. The Beacon Investors,
NewCo and the other Indemnitees under Section 7.2 shall not be entitled to seek
payment, and MAPCO and the other Indemnitees under Sections 7.3 and 7.4 shall
not be





                                       48
<PAGE>   58
entitled to seek payment, in respect of any indemnified Loss or Third Party
Claim more frequently than once each quarter in any calendar year, and then and
only then if the total of such indemnified Losses or Third Party Claims for
which payment is sought is at least $50,000 and then the Indemnitee shall be
entitled to seek payment, subject to Section 7.9(b) and 7.9(c) below, to the
full extent of such Losses or Third Party Claims; provided, however, that
during the final quarter in which payment for an indemnified Loss or Third
Party Claim may be sought as contemplated by Section 7.10, any Indemnitee may
seek payment to the full extent of such Losses or Third Party Claims subject to
Section 7.9(b) and 7.9(c) below. Notwithstanding the foregoing an Indemnitor
may make payment to an Indemnitee for an indemnified Loss or Third Party Claim
at any time so long as the Indemnitor pays all other Indemnitees for similar
Losses or Third Party Claims with similar dispatch.

                          (b)     Indemnity Threshold for Certain Items.
Notwithstanding anything to the contrary contained in Section 7.9(a), MAPCO
shall only be obligated to indemnify the Beacon Investors and the other
Indemnitees under Sections 7.2(b)(ii)(B)(I) and 7.2(c)(i) to the extent that
the aggregate amount of all Losses under Sections 7.2(b)(ii)(B)(I) and
7.2(c)(i), except for Losses resulting from breach of the representations and
warranties contained in Section 2.14, as to which this Section 7.9(b) is
inapplicable, exceeds $3,000,000 and then only to the extent such indemnifiable
Losses exceed $3,000,000; the Beacon Investors shall only be obligated to
indemnify MAPCO and the other Indemnitees under Sections 7.3(a)(i) and
7.3(b)(i) to the extent that the aggregate amount of all Losses under Sections
7.3(a)(i) and 7.3(b)(i) exceeds $3,000,000 and then only to the extent such
indemnifiable Losses exceed $3,000,000; and NewCo shall only be obligated to
indemnify MAPCO and the other Indemnitees under Sections 7.4(a)(i) and
7.4(b)(i) to the extent that the aggregate amount of all Losses under Sections
7.4(a)(i) and 7.4(b)(i) exceeds $3,000,000 and then only to the extent such
indemnifiable Losses exceed $3,000,000.

                          (c)     Limits of Indemnification Liability for
Certain Items.

                                  (i)      Notwithstanding anything contained
in this Article VII to the contrary, MAPCO shall have no indemnification
obligation under Sections 7.2(b)(ii)(B)(I) or 7.2(c)(i) in respect of Losses
(other than Losses resulting from a breach of the representations and
warranties set forth in Section 2.14 (which are not subject to any limitation),
to the extent such Losses are not indemnifiable under Section 7.2(b) or 7.2(c)
(other than Section 7.2(b)(ii)(B)(I) and Section 7.2(c)(i))  and (after giving
effect to the application of Section 7.9(b)) exceed $50,000,000 in the
aggregate.

                                  (ii)     Notwithstanding anything contained
in this Article VII to the contrary, the Beacon Investors shall have no
indemnification obligation





                                       49
<PAGE>   59
under Sections 7.3(a)(i) or 7.3(b)(i) to the extent such Losses (after giving
effect to the application of Section 7.9(b)) exceed $10,000,000.

                                  (iii)    Notwithstanding anything in this
Article VII to the contrary, NewCo shall have no indemnification obligation
under Sections 7.4(a)(i) or 7.4(b)(i) to the extent such Losses (after giving
effect to the application of Section 7.9(b)) exceed $10,000,000.

                 Section 7.10     Survival of Representations and Warranties.
All representations and warranties of the parties contained in this Agreement,
the MAPCO Agreements or the NewCo Agreements, each and every one of which
representations and warranties is strictly relied upon by the parties to whom
they are made, shall survive the Closing hereunder and continue in full force
and effect thereafter, regardless of any investigation made or to be made by or
on behalf of any party hereto, for a period ending on the date five (5) years
after the Closing Date, except for the representations and warranties of MAPCO,
provided for in Section 2.14 (which shall survive the Closing hereunder and
continue in full force and effect thereafter, regardless of any investigation
made or to be made by or on behalf of any party hereto, for a period ending
sixty days after the expiration of the relevant statutes of limitations
including any extension or waiver thereof regarding the filing of Returns and
the payment of Taxes). Except as set forth in this Section 7.10, after the end
of such period, an Indemnitor's obligation to an Indemnitee under this Article
VII with respect to such representations and warranties shall expire except
with respect to a matter set forth in a Claim Notice theretofore delivered by
an Indemnitee; provided, that the expiration of any indemnification obligations
pursuant to this Section 7.10 shall in no way constitute an assumption by any
of the Beacon Investors, NewCo or any of their respective successors or related
Indemnitees of any liabilities of MAPCO or a waiver by any of the Beacon
Investors, NewCo or any of their respective successors of any other legal
remedies they may have to seek from MAPCO or its successor reimbursement or
contribution for amounts paid or payable in respect of Excluded Liabilities. It
is further agreed that each of the Beacon Investors' and NewCo's rights to
indemnification set forth in Sections 7.2(a) and 7.2(b), and MAPCO's rights to
indemnification set forth in Sections 7.3(a) and 7.4(a), shall remain in full
force and effect indefinitely.

                 Section 7.11     After-Tax Nature of Indemnity Payments. Any
payment or indemnity required to be made pursuant to Sections 7.2, 7.3 and 7.4
hereof shall include any amount necessary to hold the indemnitee harmless on an
after-tax basis from all Taxes required to be paid with respect to the receipt
of such payment or indemnity (after taking into account any reduction in Taxes
realized by the indemnitee as a result of the Loss giving rise to the payment
or indemnity). In determining the amount necessary to be added to any payment
or indemnity in order to accomplish the foregoing, the parties hereto agree (a)
to treat all Taxes required to be paid by, and all reductions in Tax realized
by any indemnitee, as if such





                                       50
<PAGE>   60
indemnitee were subject to tax at the highest marginal tax rates applicable to
such indemnitee and (b) to treat any indemnification payments made to the NewCo
pursuant to this Agreement as an adjustment to the purchase price paid or by
MAPCO unless either party or NewCo receives a written opinion, reasonably
satisfactory in form and substance to the other party, of a law firm of
national recognized standing to the effect that it is not or is not likely to
be permissible to treat such payments in that manner on a federal, state or
local income tax return.

                                  ARTICLE VIII

any injunction or other order issued by a court of competent jurisdiction or
Governmental Authority restraining, enjoining or prohibiting, and no such
action or proceeding by any Governmental Authority shall be pending before any
court of competent jurisdiction or threatened in writing to restrain, enjoin or
prohibit the consummation of, or challenge the validity or legality of, the
transactions contemplated by this Agreement, any MAPCO Agreement or any NewCo
Agreement.

                 Section 9.6      Mediation.

                          (a)     Generally. In the event that any dispute
arises between or among the parties to this Agreement, arising out of, relating
to or in connection with this Agreement, and the parties to the dispute are
unable to resolve such dispute within a reasonable time through negotiations,
such dispute may be resolved by mediation. Any party to the dispute may request
that the matter be submitted to mediation by written notice to that effect.
Within 10 days after receipt of said notice, the other parties shall give
written notice stating whether or not they consent to mediation, provided that
no party shall be required to submit to mediation unless it consents, which
consent is in its sole discretion, and provided further that a request for
mediation shall not in any way interfere, compromise, limit or restrict a
party's right to seek any judicial remedies whatsoever.

                          (b)     Selection of Mediator. If all parties
consent, mediation shall be initiated in accordance with the Center for Public
Resources Model Procedure for Mediation of Business Disputes attached as
Exhibit K; provided, however, that the mediation shall take place in the
Borough of Manhattan in The City of New York, New York.

                          (c)     Mediation Award. Any settlement agreement
mutually reached in the course of the mediation shall be recorded in a
definitive agreement, which shall be binding and conclusive upon the parties.

                 Section 9.7      Expenses, Taxes. Except as expressly provided
herein, whether or not the transactions contemplated herein shall be
consummated, each party shall pay its own expenses incident to the preparation
and performance of this Agreement, including but not limited to the fees and
expenses of its counsel, financial advisors and accounting advisors; provided,
however, that if the Closing shall not occur and MAPCO shall not have breached
any of its obligations hereunder, 100% of the fees and expenses of Dames &
Moore and of Boyd (collectively, the "Third Party Consultants' Fees") shall be
paid by the Beacon Investors. If the Closing shall occur, the Third Party
Consultants' Fees and, whether or not the Closing shall occur, the fees and
expenses in connection with the Senior Credit Agreement shall be borne by





                                       56
<PAGE>   66
NewCo. MAPCO shall bear any transfer, documentary, sales, use, stamp,
registration, conveyance and similar taxes and fees incurred in connection with
the transactions contemplated by this Agreement other than the filing fees
required to be paid by the "acquiring party" under the HSR Act, which shall be
paid by NewCo. As between MAPCO on the one side, and NewCo, on the other side,
liability for property and ad valorem taxes relating to the assets acquired by
NewCo from MAPCO and other such Taxes payable on a periodic basis shall be
apportioned between the periods before and after the Closing Date in a manner
consistent with the principles of Section 164(d) of the Code. Fees and expenses
of Crowell & Moring incurred on or after May 1, 1996, incident to the
preparation of this Agreement and the MAPCO Agreements shall be borne equally
by MAPCO and the Beacon Investors.

                 Section 9.8      Further Actions. (a) From time to time after
the Closing, each party shall execute and deliver such certificates and other
documents and take such other actions as may reasonably be requested by the
other party in order to consummate or implement the transactions contemplated
hereby.

                          (b)     Within 90 days after the Closing, MAPCO shall
provide to the Beacon Investors and NewCo a report or reports, prepared by a
firm of independent appraisers of nationally recognized reputation, setting
forth a proposed allocation of the Total Value among the assets acquired by
NewCo from MAPCO. The parties shall cooperate in determining the final
allocation of the Total Value among such assets (the "Final Allocation"). Any
dispute with respect thereto shall be referred for resolution to a firm of
independent public accountants of national standing chosen by agreement of the
parties. The decision of such accounting firm with respect to such dispute
shall be final and binding. In connection with the preparation of the foregoing
report, reports and the Final Allocation, the parties shall cooperate with each
other and provide such information as any of them shall reasonably request. All
fees and expenses paid to third parties in connection with determining the
Final Allocation shall be divided evenly between MAPCO and the Beacon
Investors. Each of the parties and NewCo shall report the federal, state and
local and other tax consequences of the contributions contemplated hereby in a
manner consistent with the Final Allocation.

                 Section 9.9      Post-Closing Access. In connection with any
matter relating to any period prior to, or any period ending on, the Closing
Date, each of MAPCO and NewCo shall, upon the request and at the expense of the
other, permit NewCo and MAPCO, respectively, and their representatives full
access at all reasonable times to the books and records of MCI, MCMI or any of
the Coal Subs or any of their predecessors which shall have been retained by
MAPCO or NewCo (it being understood that all books and records of the Business
relating to pre-Closing periods will be jointly retained as tenants in common),
as the case may be, or transferred to NewCo, and each of NewCo and MAPCO shall
execute (and shall cause MCI, MCMI or any of the Coal Subs to execute) such
documents as MAPCO or NewCo may





                                       57
<PAGE>   67
reasonably request to enable MAPCO or NewCo to file any required reports or tax
returns relating to MCI, MCMI or any of the Coal Subs. Neither MAPCO nor NewCo
shall dispose of such books and records during the seven-year period beginning
with the Closing Date without the prior written consent of the other. Following
the expiration of such seven-year period, NewCo or MAPCO may dispose of such
books and records at any time upon giving 60 days' prior written notice to
MAPCO or NewCo, as the case may be, unless MAPCO or NewCo agrees to take
possession of such books and records within 60 days at no expense to NewCo or
MAPCO, respectively.

                 Section 9.10     Notices. All notices, requests, demands and
