This STOCK PURCHASE AGREEMENT dated as of September 15, 2000 is made and entered
into  by  and  between   Westmoreland  Coal  Company,  a  Delaware   corporation
("Purchaser"),  and Entech, Inc., a Montana corporation ("Seller").  Capitalized
terms not otherwise defined herein have the meanings set forth in Section 12.01.

WHEREAS,  Seller  owns all of the  outstanding  shares of common  stock,  no par
value, of Basin Resources, Inc., a Colorado corporation,  Horizon Coal Services,
Inc.,  a  Montana   corporation,   North  Central  Energy  Company,  a  Colorado
corporation,   Western  Energy  Company,  a  Montana  corporation  ("WECO")  and
Northwestern  Resources  Co., a Montana  corporation  ("NWR") (each, a "Company"
and, collectively, the "Companies"), such shares being referred to herein as the
"Shares"; and

WHEREAS,  Seller desires to sell, and Purchaser desires to purchase,  the Shares
on the terms and subject to the conditions set forth in this Agreement;

NOW,  THEREFORE,  in  consideration  of the mutual  covenants and agreements set
forth in this  Agreement,  and for other good and  valuable  consideration,  the
receipt and  sufficiency  of which are hereby  acknowledged,  the parties hereto
agree as follows:

                                   ARTICLE I
                           SALE OF SHARES AND CLOSING

1.01 Purchase and Sale. Seller agrees to sell to Purchaser, and Purchaser agrees
to purchase from Seller,  all of the right,  title and interest of Seller in and
to the Shares at the  Closing on the terms and  subject  to the  conditions  set
forth in this Agreement.

1.02 Purchase Price. The aggregate purchase price for the Shares is $138,000,000
(the  "Purchase  Price"),  subject to  adjustment  as provided in Section  1.04,
payable in  immediately  available  United  States  funds at the  Closing in the
manner provided in Section 1.03.

1.03  Closing.  The Closing  will take place at the  offices of Milbank,  Tweed,
Hadley & McCloy LLP, 1 Chase  Manhattan  Plaza,  New York, New York 10005, or at
such other place as Purchaser and Seller  mutually  agree,  at 10:00 A.M.  local
time, on the Closing Date. At the Closing, Purchaser will pay the Purchase Price
by wire transfer of  immediately  available  funds to such account as Seller may
reasonably  direct by written  notice  delivered to Purchaser by Seller at least
two (2)  Business  Days before the  Closing  Date.  Simultaneously,  Seller will
assign and transfer to Purchaser  all of Seller's  right,  title and interest in
and to the Shares by  delivering  to  Purchaser a  certificate  or  certificates
representing  the Shares,  in genuine and unaltered form, duly endorsed in blank
or accompanied by duly executed stock powers  endorsed in blank,  with requisite
stock transfer tax stamps, if any, attached. At the Closing, there shall also be
delivered  to Seller  and  Purchaser  the  certificates  to be  delivered  under
Articles VI and VII.

1.04     Purchase Price Adjustment.

     (a) Promptly  following the Closing Date,  representatives  of Seller shall
expeditiously  perform  such  procedures  with  respect to the  Companies as are
necessary and appropriate to prepare (on a basis consistent with the preparation
of  the  Interim   Financial   Statements)  a  certificate  (the  "Closing  Date
Certificate") setting forth Seller's calculation, as of the Closing Date, of (i)
the aggregate  value of the Net Assets of the Companies (the "Net Asset Value"),
and (ii) if the Closing Date occurs after December 31, 2000, the Net Revenues of
the  Companies  from January 1, 2001 up to and  including  the Closing Date (the
"Net Revenue  Amount").  Purchaser  shall provide Seller with full access at all
reasonable times to the Companies' books, records,  premises and other materials
and the Companies' workpapers and shall furnish Seller with such information and
assistance as Seller may reasonably  request in connection  with the preparation
of the Closing  Date  Certificate.  Seller shall make all of its work papers and
other relevant  documents in connection with the preparation of the Closing Date
Certificate  available  to Purchaser  and  Purchaser's  independent  accountants
("Purchaser's  Accountants"),  and  shall  make the  persons  in  charge  of the
preparation of the Closing Date Certificate  available for reasonable inquiry by
Purchaser  and  Purchaser's  Accountants.  Seller shall deliver the Closing Date
Certificate  to Purchaser  not later than sixty (60) days  following the Closing
Date.

     (b) Unless Purchaser provides written notice to Seller of an objection to a
material aspect of the Closing Date Certificate  before the thirtieth (30th) day
following receipt of the Closing Date Certificate,  the Closing Date Certificate
shall then become  binding upon Purchaser and Seller.  If Purchaser,  by written
notice to Seller  before  the close of  business  on the  thirtieth  (30th)  day
following  receipt of the  Closing  Date  Certificate,  objects to any  material
aspect of the  Closing  Date  Certificate,  then  those  aspects as to which the
objection was made shall not become binding.  Purchaser and Seller shall discuss
such  objection and, if they reach written  agreement  amending the Closing Date
Certificate,  then the  Closing  Date  Certificate,  as amended by such  written
agreement, shall then become binding upon Purchaser and Seller. If Purchaser and
Seller cannot reach  agreement  within fifteen (15) days after  Purchaser  gives
such notice of objection,  their  disagreements shall be promptly submitted to a
nationally recognized  independent  accountant (the "Independent  Accountants"),
which  shall  conduct  such  additional  review as is  necessary  to resolve the
specific  disagreements  referred to it and, based thereon,  shall determine the
final Closing Date Certificate.  The review of the Independent  Accountants will
be  restricted  as to scope to address only those matters as to which Seller and
Purchaser have not reached  agreement  pursuant to the preceding  sentence.  The
Independent  Accountants'  determination of the Closing Date Certificate,  which
shall be completed as promptly as practicable  but in no event later than thirty
(30)  days  following  its  selection,  shall be  confirmed  by the  Independent
Accountants  in writing  to, and shall be final and binding  on,  Purchaser  and
Seller for purposes of this Section 1.04.

     (c) In the  event  the  Net  Asset  Value  determined  in  accordance  with
subparagraph (a) or (b) of this Section 1.04, as the case may be (the "Final Net
Asset  Value"),  is (A) less than  $97,120,000  (such  difference  being  herein
referred  to as the "Net  Asset  Deficiency  Amount"),  Seller  shall,  promptly
following the date of determination of the Final Net Asset Value (the "Net Asset
Determination  Date"), pay to Purchaser an amount in immediately available funds
equal to the Net Asset  Deficiency  Amount or (B) more  than  $97,120,000  (such
difference  being  herein  referred  to as  the  "Net  Asset  Surplus  Amount"),
Purchaser shall,  promptly  following the Net Asset  Determination  Date, pay to
Seller an amount in immediately  available  funds equal to the Net Asset Surplus
Amount.

     (d) In the event the Closing occurs after December 31, 2000,  Seller shall,
promptly  following  the date of  determination  of the Net  Revenue  Amount  in
accordance with subparagraph (a) or (b) of this Section 1.04, as the case may be
(the "Final Net Revenue  Amount"),  pay to  Purchaser  an amount in  immediately
available funds equal to the Final Net Revenue Amount.

     (e) The fees and  expenses of the  Independent  Accountants  shall be split
equally between Seller, on the one hand, and Purchaser, on the other.

     (f)  Any  payment  pursuant  to this  Section  1.04  shall  be made by wire
transfer of immediately available funds to a single account designated by Seller
or  Purchaser,  as the case may be,  and shall be  accompanied  by payment of an
amount  determined by computing simple interest on the amount of that payment at
the "prime rate" (as such rate is reported in The Wall Street  Journal under the
heading,  "Money  Rates,"  or if such  rate is no longer  published  in the Wall
Street Journal,  as reported by Citibank NA as its prime rate) on the basis of a
365-day year and the actual  number of days elapsed from the Closing Date to the
date of payment.

1.05 Further Assurances;  Post-Closing Cooperation. (a) Subject to the terms and
conditions  of  this  Agreement,  at any  time or from  time to time  after  the
Closing,  each of the  parties  hereto  shall  execute  and  deliver  such other
documents and instruments,  provide such materials and information and take such
other actions as may reasonably be necessary, proper or advisable, to the extent
permitted by Law, to fulfill its obligations under this Agreement.

     (b)  Following  the Closing,  each party will afford the other  party,  its
counsel and its accountants,  during normal business hours, reasonable access to
the books,  records and other data  relating to the Business or Condition of the
Companies in its possession with respect to periods prior to the Closing and the
right to make copies and extracts therefrom,  to the extent that such access may
be  reasonably  required  by the  requesting  party in  connection  with (i) the
preparation of Tax Returns,  (ii) the determination or enforcement of the rights

representations and warranties of Seller contained in this Agreement,  as to any
other  information  relating to the Companies,  the Subsidiary or their business
furnished or to be furnished to Purchaser or its representatives by or on behalf

have visited the active  operations of the Companies and the Subsidiary and have
been  given  opportunities  to  examine  the Books and  Records  Seller has made
available relating to the Companies,  the Subsidiary and their business.  Except
as expressly provided in this Agreement,  neither Seller nor any Company nor the
Subsidiary  shall have any  liability to Purchaser  or its  Affiliates,  agents,
representatives or employees resulting from any use, authorized or unauthorized,

its Affiliates to violate any material  limitations or parameters  imposed in 43
C.F.R. Part 3400.

     (b) As of the execution and delivery  hereof and after giving effect to the
purchase of the Companies and the Subsidiary,  Purchaser and its Affiliates will

State of Montana pursuant to applicable laws and regulations.

notified (nor is there any pending or, to the knowledge of Purchaser, threatened
notification)  by the United States Office of Surface  Mining,  Reclamation  and
Enforcement  (OSMRE)  or  the  agency  of any  state  administering  SMCRA  that
Purchaser or any of its Affiliates is (i)  ineligible to receive  surface mining

unreasonably withheld.

     (b) Treatment of Scheduled Bonds. (i) Without limiting Section 5.03(a),  at
the Closing,  Purchaser shall post a replacement letter of credit or surety bond
or other  instrument  for the benefit of the  beneficiaries  thereof in form and
substance reasonably satisfactory to Seller and relevant regulators,  and issued
by a financial institution reasonably  satisfactory to Seller in respect of each
letter of credit,  surety bond and other obligation disclosed in Section 5.03(b)
of  the  Disclosure  Schedule,  as it  may  be  supplemented  prior  to  Closing
(collectively,  the "Scheduled Bonds"). At the Closing, Purchaser shall deliver,
or cause to be delivered,  to Seller,  such other documents as may reasonably be
requested  by Seller in order to permit  Seller to effect the full  release  and
discharge  of  Seller  and its  Affiliates  (other  than  the  Companies  or the
Subsidiary) as contemplated hereby; and (ii) with respect to all Scheduled Bonds
that remain  outstanding  following  the Closing  Date,  Purchaser  shall pay to
Seller a monthly fee during the applicable month, such fee to commence to accrue
as of the Closing  equal in amount to Seller's  actual  premium,  fee or similar
cost payable by Seller for such guarantee,  indemnity,  letter of credit, letter
of  comfort,  surety  bond,  self-bond,  performance  bond or  other  obligation
attributable to such month,  plus interest  thereon at the "prime rate" (as such
rate is reported in The Wall Street Journal under the heading, "Money Rates," or
if such rate is no longer  published in The Wall Street Journal,  as reported by
Citibank  NA as its prime  rate) on the basis of a 365-day  year and the  actual
number of days in such month (or  partial  month in the case of the first  month
such fee is payable commencing with the Closing Date and the last month such fee
is  payable  commencing  with the  Closing  Date and the last  month such fee is
payable ending on the date such obligation is replaced, released or discharged).
Any such fee payable by Purchaser  shall become due and payable on the first day
following  the month (or portion  thereof) in which such fee shall have  accrued
and shall be  computed on a per annum  basis  based on a 365-day  year,  and the
actual number of days elapsed from the Closing Date to the date of payment.  For
purpose of such calculation,  a Scheduled Bond shall be deemed to be outstanding
until such time as the  beneficiary  thereof has  provided  Seller with  written
documentation  sufficient  in the judgment of Seller to cause the Seller and any
Affiliates to be fully released and discharged  from the Scheduled Bond, and the
Scheduled Bond has been returned to Seller.

5.04     Employee Matters.

     (a) Continuation of Compensation and Benefits. Except as otherwise provided
in Sections  5.04(f),  (g), (h) and (j), during the period from the Closing Date
until twenty-four months following the Closing Date,  Purchaser will maintain or
will cause to be  maintained,  or shall cause each Company and the Subsidiary to
maintain,   base  salary,   wages,   compensation  levels  (including,   without
limitation,  incentive  compensation)  and employee  pension and welfare benefit
plans and  programs  for the benefit of the  employees  of each  Company and the
Subsidiary,  which,  in the  aggregate,  are at least equal to, or equivalent in
value to, the wages,  compensation  levels,  and Benefit Plans listed in Section
2.12(a) of the Disclosure  Schedule provided to the employees of such Company or
the Subsidiary on the date of this Agreement,  plus any salary  adjustments made
in the ordinary  course of business  between the date of this  Agreement and the
Closing Date.  For purposes of this Section 5.04,  the employees of each Company
and the Subsidiary on the Closing Date shall be the employees  listed on Section
2.12(b) of the  Disclosure  Schedule,  as modified  through the Closing  Date to
reflect  employment  changes  due  to  additions,  dismissals,   retirements  or
transfers (all in accordance with Section 4.05).

     (b)  Service  Credit.  The  Purchaser  shall  provide,  or shall cause each
Company and the  Subsidiary  to provide,  each  employee of each Company and the
Subsidiary  with credit for all service with each Company,  the  Subsidiary  and
their Affiliates for all purposes under each employee benefit plan,  program, or
arrangement  of the  Purchaser  or its  Affiliates  in which  such  employee  is
eligible to  participate,  except to the extent that such  service  credit would
result in a duplication of benefits with respect to the same period of service.

     (c) Bonuses;  Incentive  Compensation.  The bonus plans and other incentive
compensation  plans  and  programs  maintained  by  Seller  and/or  any  of  its
Affiliates  in which  the  employees  of each  Company  and the  Subsidiary  are
eligible to participate  (including  terminated or retired  employees who remain
eligible to participate under the terms of such plans), as in effect on the date
of this  Agreement,  shall be terminated by Seller as of the Closing Date,  with
the bonuses and incentive  compensation  through such date to be paid thereunder
by Seller in the  amounts  determined  by Seller  within 90 days of the  Closing
Date.

     (d)  Severance  Policy  and  Other  Agreements.  If the  employment  of any
employee of any  Company or the  Subsidiary  is  terminated  within  twenty four
months  after the Closing  Date by (i) action of Purchaser or any Company or the
Subsidiary  other than for Cause, or (ii) action of an employee  following (A) a
reduction  in such  employee's  base  salary  equal to or greater  than  fifteen
percent  (15%) or (B) such  employee's  decision not to relocate more than fifty
(50) miles from his or her then current job location,  then Purchaser shall pay,
or shall cause such Company or the  Subsidiary to pay, each such employee a lump
sum  severance  benefit (less  required tax  withholding  and other  withholding
obligations  required  by  statute)  in an  amount  equal  to the sum of (x) the
product  of  ten  percent  (10%)  of  such  employee's  annualized  base  salary
multiplied by such employee's  "years of service" up to a maximum of one hundred
percent (100%) of such base salary, plus (y) six thousand dollars ($6,000).  For
purposes  of the  foregoing,  "years  of  service"  shall  mean  the  employee's
aggregate  total years of service  (pro-rated to the date of  termination)  with
such Company, the Subsidiary,  Purchaser and any of their respective Affiliates.
Notwithstanding  the  foregoing,  if the  employee  is a party to an  individual
change in control severance agreement with such Company or the Subsidiary or any
of its  Affiliates,  the  terms  of such  agreement  shall  apply in lieu of the
foregoing with respect to any termination of such employee, and the consummation
of the transaction contemplated by this Agreement will be deemed to constitute a
"Change in Control" for purposes of each such agreement.  Purchaser shall honor,
or cause such Company or the Subsidiary to honor, all such individual  change in
control  severance  agreements with such  employees,  and the Purchaser shall be
liable for any amount(s) or benefit(s) due thereunder.

     (e) Benefit Plan  Obligations.  Except for the matters disclosed in Section
5.04(e) of the  Disclosure  Schedule or as  otherwise  provided in this  Section
5.04,  Purchaser  shall be, or shall cause such Company or the Subsidiary to be,
responsible for all obligations existing on the Closing Date (including, without
limitation, any such obligations that have been incurred but not yet paid) under
any Benefit Plan (including,  without limitation,  all health and welfare,  life
insurance and disability plans and programs) applicable to the employees of such
Company or of the Subsidiary, and effective as of the Closing Date, MPC, Seller,
and their Affiliates  (other than such Company or the Subsidiary)  shall have no
liability or responsibility for any obligation under any Benefit Plan applicable
to the  employees  of such  Company or the  Subsidiary,  with  respect to claims
incurred by such employees or their covered dependents prior to the Closing Date
under each Benefit Plan.  Expenses and benefits with respect to claims  incurred
by employees of each Company or the Subsidiary or their covered dependents on or
after the Closing Date shall be the responsibility of Purchaser. For purposes of
this  paragraph,  a claim is  deemed  incurred  when the  services  that are the
subject  of the claim are  performed;  in the case of life  insurance,  when the
death occurs, and, in the case of short-term or long-term  disability  benefits,
when the disability occurs.  Purchaser shall, or shall cause each Company or the
Subsidiary  to,  (i)  waive  all  limitations  as  to  preexisting   conditions,
exclusions  and waiting  periods  with  respect to  participation  and  coverage
requirements  applicable to the employees of each Company or the Subsidiary (who
are  employees of such Company or the  Subsidiary on the Closing Date) under any
Benefit Plan that such  employees  may be eligible to  participate  in after the
Closing  Date;  provided that any  limitations  as to  pre-existing  conditions,
exclusions  and waiting  periods  which  apply  prior to the Closing  Date shall
continue to apply after the Closing Date and (ii) provide each  employee of each
Company or the Subsidiary  (who is an employee of such Company or the Subsidiary
on the Closing Date) with credit for any co-payments and deductibles  paid prior
to the Closing Date in satisfying  any  applicable  deductible or  out-of-pocket
requirements  under any  Benefit  Plan in which such  employee  is  eligible  to
participate after the Closing Date.

     (f) 401(k) Plan. Effective as of the Closing Date, Purchaser shall provide,
or shall cause each  Company and the  Subsidiary  to provide,  for the  eligible
employees of each Company or the  Subsidiary a plan  pursuant to Section  401(a)
and  Section  401(k) of the Code (the  "Purchaser's  401(k)  Plan")  which shall
provide for elective  deferral and loan  entitlements,  and which shall  further
provide  for  the   acceptance  of  a  trust  to  trust  transfer  and  rollover
distributions  from MPC's Qualified Plans and/or conduit  individual  retirement
accounts  established by any such  employees.  Purchaser  shall take all actions
required to obtain, and shall obtain, a favorable  determination letter from the
IRS on the tax qualified  status of Purchaser's  401(k) Plan.  Employees of each
Company and the Subsidiary  shall cease to accrue  benefits and service  credits
under The Montana Power Company and  Subsidiaries  Employee  Retirement  Savings
Plan (the "Seller's 401(k) Plan") as of the Closing Date.

     (g) Pension Plan. To the extent that Purchaser  maintains a defined benefit
pension plan pursuant to Section  401(a) of the Code (the  "Purchaser's  Pension
Plan") that provides  accrued  benefits to eligible  employees of any Company or
the Subsidiary at least equal to the accrued  benefits of those  employees as of
the Closing Date under The Montana  Power  Company  Pension Plan (the  "Seller's
Pension Plan"),  assets and/or cash, as determined by MPC, equal to such accrued
benefits shall be transferred from Seller's Pension Plan to Purchaser's  Pension
Plan. The assets and/or cash to be transferred to Purchaser's Pension Plan shall
equal the  aggregate  present  value of such accrued  benefits on a  termination
basis as of the Closing Date (within the meaning of Treasury  Regulation Section
1.414(l)-1(b)(5)  and based on the "expected  retirement age" as defined in PBGC
Regulations  and  the  PBGC  termination  interest  rate  for  annuity  purposes
(currently  such interest rate  effective for September 2000 as published by the
PBGC is 7.00% for the next 25 years and 6.25%  thereafter)  for pension plans as
of the Closing Date), as certified by Seller's  actuary.  The transfer of assets
and/or cash to  accomplish  the above  shall  occur as soon as  administratively
possible  after the Closing  Date.  As of the Closing  Date,  employees  of each
Company and the Subsidiary  shall cease to participate in Seller's Pension Plan,
and no further benefits shall be accrued under Seller's Pension Plan. The amount
of assets and/or cash to be so transferred shall bear interest at the above PBGC
interest rate from the Closing Date to the date of such transfer.

     (h) Continuing Obligation.  If Purchaser sells or otherwise disposes of all
or  substantially  all of the stock or assets of any  Company or the  Subsidiary
within  twenty-four months of the Closing Date, or such other longer time period
as may be applicable to any  individual  change in control  severance  agreement
between an  employee of any Company or the  Subsidiary  and such  Company or the
Subsidiary or any of its  Affiliates,  Purchaser  shall, in connection with such
disposition cause the transferee of such stock or assets to honor the provisions
of this Section 5.04 until  twenty-four  months after the Closing  Date, or such
other longer time period as may be  applicable  under any  individual  change in
control severance agreement.

     (i) Collective Bargaining  Agreements.  The wages,  compensation levels and
employee  pension  and welfare  benefit  plans and  programs  for the benefit of
employees of the  Companies and the  Subsidiary  who are covered by a collective
bargaining  agreement  shall  be  governed  by  the  terms  of  such  collective
bargaining agreement,  except (i) to the extent that an employee is eligible for
the benefits provided under Section 5.04(c) and (ii) Section 5.04(b) shall apply
with respect to all such  employees.  In no event shall Section 5.04(d) apply to
such employees.  To the extent of the terms or provisions of any such collective
bargaining  agreement  conflict  with  any of the  terms or  provisions  of this
Agreement,  the terms or provisions of the collective bargaining agreement shall
govern.

5.05 Fulfillment of Conditions.  Purchaser will take all commercially reasonable
steps necessary or desirable and proceed diligently and in good faith to satisfy
each condition to the obligations of Seller contained in this Agreement and will
not take or fail to take any action that would result in the  nonfulfillment  of
any such condition.

5.06 Communication  Between the Parties. If Purchaser develops information prior
to the Closing  Date that leads  Purchaser to believe that Seller has breached a
representation  or warranty under this Agreement,  Purchaser shall inform Seller
of such potential  breach as soon as possible,  but in any event, at or prior to
Closing.

5.07 Financing. Purchaser will use commercially reasonable efforts to obtain, on
or prior to the Closing Date,  senior debt  financing in an amount not more than
$110,400,000,  on terms  currently  prevailing  in the  market  for  acquisition
financings of this nature (the  "Financing"),  of use in funding  payment of the
amount due from Purchaser at Closing  pursuant to this Agreement.  Purchaser has
no reason to believe it will not obtain  such Debt  Financing  by Closing  Date.
Purchaser will use commercially reasonable efforts to obtain, on or prior to the
Closing Date, the Equity Financing.

                       TAX MATTERS AND POST-CLOSING TAXES

8.01 Income Taxes.  (a) Seller shall prepare or cause to be prepared and file or
cause to be filed all Income Tax Returns for the  Companies  and the  Subsidiary
for all periods ending on or prior to the Closing Date which are filed after the
Closing Date.  Each Company and the Subsidiary  will furnish Tax  information to
Seller and MPC for  inclusion in the relevant  Income Tax Returns in  accordance
with the past custom and practice of the Companies. Seller shall pay all amounts
shown as owing on such Income Tax Returns,  and shall be liable for Income Taxes
of each Company and the Subsidiary for periods ending on or prior to the Closing
Date.

     (b) Seller  shall  prepare or cause to be prepared and Seller shall file or
cause to be filed any Income Tax Returns of the Companies and the Subsidiary for
Tax periods  which begin before the Closing Date and end after the Closing Date,
provided that Seller is obligated to file such returns only following review and
approval by Purchaser,  which  approval  shall not  unreasonably  be withheld or
delayed.  Each Company and the Subsidiary will furnish Tax information to Seller
and MPC for inclusion in the relevant  Income Tax Returns in accordance with the
past custom and practice of the Companies and the  Subsidiary.  Seller shall pay
to Purchaser  within fifteen  business days after the date on which Income Taxes
are paid with  respect  to such  periods an amount  equal to the  portion of the
amounts  shown as owing on such Tax Returns which relates to the portion of such
Tax  period  ending on the  Closing  Date to the  extent  such  amounts  are not
reflected in a reserve for tax liability on such  Company's or the  Subsidiary's
financial statements made available to Purchaser pursuant to Section 2.08(a)(ii)
or Section  4.06  hereof.  The portion of such  Income Tax which  relates to the
portion of such Tax period  ending on the Closing  Date shall be deemed equal to
the  amount  which  would be  payable if the  relevant  Tax period  ended on the
Closing Date.  Any credits  relating to a Tax period that begins before and ends
after the Closing  Date shall be taken into  account as though the  relevant Tax
period ended on the Closing Date. All determinations necessary to give effect to
the foregoing  allocations  shall be made by Seller in a manner  consistent with
prior practice of the Companies and the  Subsidiary.  Seller shall be liable for
Income  Taxes of each  Company  and the  Subsidiary  which are  attributable  to
periods ending on or prior to the Closing Date pursuant to this Section  8.01(b)
to the extent such Taxes are not  reflected  in a reserve for tax  liability  on
such Company's or the  Subsidiary's  financial  statements made available to the
Purchaser  pursuant to Section  2.08(a)(ii)  or Section 4.06  hereof.  Purchaser
shall be liable for Income  Taxes of each Company and the  Subsidiary  which are
attributable to periods after the Closing Date pursuant to this Section 8.01(b).

8.02 Taxes Other Than Income  Taxes.  (a) Seller shall  prepare and file for the
Companies and the  Subsidiary  all Tax Returns for Taxes other than Income Taxes
required to be filed on or prior to the Closing Date.  Seller shall prepare such
Tax Returns in a manner consistent with the prior practices of the Companies and
the Subsidiary and shall pay all amounts shown as due on such Tax Returns.

     (b) Purchaser  shall prepare and file for the Companies and the  Subsidiary
all Tax Returns for Taxes other than Income Taxes required to be filed after the
Closing  Date,  even if such Tax Returns  relate to periods prior to the Closing
Date. Purchaser shall pay all amounts shown as due on such Tax Returns and shall
be liable for all Taxes other than Income  Taxes  properly  attributable  to the
periods covered by such returns.

8.03 Tax Adjustments.  (a) Any Income Tax refunds that are received by Purchaser
or any Company or the Subsidiary that relate to Tax periods or portions  thereof
ending on or before the  Closing  Date shall be for the  account of Seller,  and
Purchaser  shall pay over to Seller  any such  refund or the  amount of any such
credit within fifteen days after receipt or entitlement thereto. In addition, to
the  extent  that a claim for refund or a  proceeding  results in a payment by a
taxing  authority to Purchaser  or any Company or the  Subsidiary  of any amount
accrued  on  such  Company's  or  the  Subsidiary's  financial  statements  made
available to Purchaser  pursuant to Section  2.08(a)(ii) or Section 4.06 hereof,
Purchaser  shall pay such amount to Seller within  fifteen days after receipt or
entitlement thereto.

     (b) Any increase in Income Tax  liability of any Company or the  Subsidiary
which is the responsibility of Seller under the provisions of Section 4.01(a) or
Section  4.01(b)  shall  be paid by  Seller  to the  Purchaser  or the  relevant
Governmental  or Regulatory  Authority as  appropriate,  provided Seller has the
right to control  the  handling  and  disposition  of the audit and any  related
administrative  or court  proceeding  which might gave rise to such  increase in
Income Tax  liability of any Company or the  Subsidiary.  Purchaser  shall,  and
shall cause such Company or the Subsidiary to,  cooperate fully with Seller with
respect  to  the  handling  and   disposition  of  any  such  audit  or  related
administrative or court proceeding.

     (c) Any  increase  or  decrease  in Taxes  other than  Income  Taxes of any
Company or the Subsidiary resulting from adjustments made after the Closing Date
shall be for the account of Purchaser.

8.04 Tax Sharing  Agreements.  All tax sharing  agreements or similar agreements
with respect to or involving any Company or the  Subsidiary  shall be terminated
as of the  Closing  Date  and,  after  the  Closing  Date,  no  Company  nor the
Subsidiary shall be bound thereby or have any liability thereunder.

8.05 Transfer Taxes. All transfer, documentary, sales, use, stamp, registration,
and other such Taxes and fees (including any penalties and interest) incurred in
connection with this Agreement shall be split equally between Seller, on the one
hand,  and  Purchaser on the other,  when due, and  Purchaser  will,  at its own
expense,  file all necessary Tax Returns and other documentation with respect to
all such transfer,  documentary, sales, use, stamp, registration and other Taxes
and fees, and, Seller will, if necessary,  join in the execution of any such Tax
Returns and other documentation.

8.06 Post-Closing Elections. At MPC's or Seller's request,  Purchaser will cause
any  Company and the  Subsidiary  to make and/or join with MPC in making any tax
election  if the making of such  election,  together  with the cost of all other
elections made pursuant to this Section, does not exceed $250,000.

8.07 Post-Closing  Transactions not in the Ordinary Course. Purchaser and Seller
agree  to  report  all  transactions  not in the  ordinary  course  of  business
occurring  on the Closing  Date after  Purchaser's  purchase of the stock of the
Companies on Purchaser's  federal  income tax return to the extent  permitted by
Treas. Reg. section 1.1502-76(b)(1)(B).

8.08  Allocation of Purchase Price. To the extent that Purchaser and Seller make
a Code  Section  338(h)(10)  election  as  provided  in  Section  8.09  of  this
Agreement,  Purchaser  and Seller shall  cooperate  fully with each other in the
making of such election. In particular, and not by way of limitation,  Purchaser
and Seller  shall,  within 90 days of the  Closing  Date,  jointly  prepare  and
execute  Internal  Revenue Service Forms 8023 and 8594 and any attachments to be
filed therewith,  in accordance with applicable law.  Purchaser,  the Companies,
the Subsidiary and MPC will file all Tax Returns  (including all amended returns
and claims for refund) and information  reports in a manner consistent with such
allocation.

8.09  Section  338(h)(10)  Election.  MPC will join with  Purchaser in making an
election under Code Section  338(h)(10) (and any  corresponding  elections under
state,  local,  or foreign tax law) with respect to the purchase and sale of the
stock of the Companies hereunder.

                                   ARTICLE IX

                       SURVIVAL; NO OTHER REPRESENTATIONS

9.01  Survival  of  Representations  and  Warranties.  The  representations  and
warranties  contained in this  Agreement  will survive the Closing until six (6)
months after the Closing Date, except that any  representation and warranty that
would  otherwise  terminate  will  continue  to  survive  if a Claim  Notice  or
Indemnity  Notice (as  applicable)  shall have been  timely  given in good faith
based on facts reasonably expected to establish a valid claim under Article X on
or prior to such termination  date, until the related claim for  indemnification
has been satisfied or otherwise resolved as provided in Article X.

9.02  No  Other  Representations.   Notwithstanding  anything  to  the  contrary
contained in this Agreement, it is the explicit intent of each party hereto that
neither Seller nor anyone on its behalf,  including its advisor Goldman, Sachs &
Co., is making any  representation or warranty  whatsoever,  express or implied,
except those  representations  and  warranties  made by Seller and  contained in
Article  II and in any  certificate  delivered  pursuant  to  Section  6.03.  In
particular, Seller makes no representation or warranty to Purchaser with respect
to (i) the information set forth in the confidential offering memorandum or (ii)
any financial  projection  or forecast  relating to the Business or Condition of
the  Companies.  With respect to any  projection or forecast  delivered by or on

                     (B) (i) With respect to all Adverse Consequences other than

         of $1,750,000 in the aggregate; or

                  (ii) Solely with respect to Section  2.19,  unless,  until and

                     (D) unless the Indemnified Party has given the Indemnifying
         Party a Claim Notice or Indemnity Notice,  as applicable,  with respect
         to such claim,  setting forth in reasonable  detail the specific  facts
         and  circumstances   pertaining  thereto,  (A)  as  soon  as  practical
         following  the  time at  which  the  Indemnified  Party  discovered  or
         reasonably should have discovered such claim and (B) in any event prior
         to the applicable Cut-off Date; or

                  (ii) to the extent that the Indemnified Party had a reasonable
opportunity,  but failed,  in good faith to mitigate  the Adverse  Consequences,
including but not limited to the failure to use commercially  reasonable efforts
to recover under a policy of insurance or under a  contractual  right of set-off
or indemnity.

10.02  Method  of  Asserting  Claims.  All  claims  for  indemnification  by any
Indemnified Party under Section 10.01 will be asserted and resolved as follows:

     (a) In the event any claim or  demand in  respect  of which an  Indemnified
Party might seek indemnity under Section 10.01 is asserted  against or sought to
be collected  from such  Indemnified  Party by a Person other than Seller or any
Affiliate of Seller or of Purchaser (a "Third  Party  Claim"),  the  Indemnified
Party  shall  deliver  a  Claim  Notice  with   reasonable   promptness  to  the
Indemnifying  Party. The Indemnifying Party will notify the Indemnified Party as
soon as practicable  within the Dispute Period  whether the  Indemnifying  Party
disputes its liability to the Indemnified  Party under Section 10.01 and whether
the  Indemnifying  Party  desires,  at its sole cost and expense,  to defend the
Indemnified Party against such Third Party Claim.

                  (i) If the Indemnifying  Party notifies the Indemnified  Party
         within the Dispute Period that the Indemnifying Party desires to defend
         the Indemnified Party with respect to the Third Party Claim pursuant to
         this Section 10.02(a),  then the Indemnifying Party will have the right
         to defend, at the sole cost and expense of the Indemnifying Party, such
         Third Party Claim by all  appropriate  proceedings,  which  proceedings
         will be vigorously and diligently  prosecuted by the Indemnifying Party
         to a final  conclusion  or will be  settled  at the  discretion  of the
         Indemnifying Party (but only with the consent of the Indemnified Party,
         which  consent will not be  unreasonably  withheld,  in the case of any
         settlement  that  provides  for any relief  other  than the  payment of
         monetary damages as to which the Indemnified  Party will be indemnified
         in full). The Indemnifying Party will have full control of such defense
         and  proceedings,  including  (except as  provided  in the  immediately
         preceding sentence) any settlement thereof; provided,  however, that if
         requested by the Indemnifying Party, the Indemnified Party will, at the
         sole cost and expense of the  Indemnifying  Party,  cooperate  with the
         Indemnifying  Party and its counsel in contesting any Third Party Claim
         that the Indemnifying  Party elects to contest,  or, if appropriate and
         related  to  the  Third  Party  Claim  in   question,   in  making  any
         counterclaim against the Person asserting the Third Party Claim, or any
         cross-complaint against any Person (other than the Indemnified Party or
         any of its  Affiliates).  The  Indemnified  Party may  retain  separate
         counsel to represent it in, but not control,  any defense or settlement
         of any Third Party Claim controlled by the Indemnifying  Party pursuant
         to this clause (i), and the  Indemnified  Party will bear its own costs
         and expenses with respect to such separate  counsel  except as provided
         in the preceding  sentence and except that the Indemnifying  Party will
         pay the costs  and  expenses  of such  separate  counsel  if (x) in the
         Indemnified  Party's good faith  judgment,  it is  advisable,  based on
         advice of  counsel,  for the  Indemnified  Party to be  represented  by
         separate  counsel  because a  conflict  or  potential  conflict  exists
         between the  Indemnifying  Party and the  Indemnified  Party or (y) the
         named parties to such Third Party Claim  include both the  Indemnifying
         Party and the Indemnified Party and the Indemnified Party determines in
         good faith, based on advice of counsel,  that defenses are available to
         it that are unavailable to the Indemnifying Party.  Notwithstanding the
         foregoing, the Indemnified Party may retain or take over the control of
         the defense or settlement of any Third Party Claim the defense of which
         the Indemnifying  Party has elected to control if the Indemnified Party
         irrevocably  waives its right to  indemnity  under  Section  10.01 with
         respect to such Third Party Claim.

                  (ii) If the Indemnifying Party fails to notify the Indemnified
         Party within the Dispute Period that the Indemnifying  Party desires to
         defend the Third Party Claim  pursuant  to Section  10.02(a),  then the
         Indemnified  Party will have the right to defend,  at the sole cost and
         expense  of the  Indemnifying  Party,  the  Third  Party  Claim  by all
         appropriate  proceedings,  which  proceedings  will be  vigorously  and
         diligently prosecuted by the Indemnified Party to a final conclusion or
         will be settled at the  discretion of the  Indemnified  Party (with the
         consent  of  the  Indemnifying   Party,   which  consent  will  not  be
         unreasonably withheld). The Indemnified Party will have full control of
         such  defense  and  proceedings,  including  (except as provided in the
         immediately  preceding  sentence)  any  settlement  thereof;  provided,
         however,  that if requested by the Indemnified  Party, the Indemnifying
         Party  will,  at the sole cost and expense of the  Indemnifying  Party,
         cooperate with the Indemnified  Party and its counsel in contesting any
         Third Party Claim which the  Indemnified  Party is  contesting,  or, if
         appropriate and related to the Third Party Claim in question, in making
         any counterclaim against the Person asserting the Third Party Claim, or
         any  cross-complaint  against any Person  (other than the  Indemnifying
         Party  or  any  of  its  Affiliates).   Notwithstanding  the  foregoing
         provisions of this clause (ii), if the Indemnifying  Party has notified
         the Indemnified  Party within the Dispute Period that the  Indemnifying
         Party disputes its liability  hereunder to the  Indemnified  Party with
         respect to such Third  Party  Claim and if such  dispute is resolved in
         favor of the Indemnifying  Party in the manner provided in clause (iii)
         below,  the  Indemnifying  Party will not be required to bear the costs
         and expenses of the Indemnified Party's defense pursuant to this clause
         (ii)  or of  the  Indemnifying  Party's  participation  therein  at the
         Indemnified  Party's request,  and the Indemnified Party will reimburse
         the  Indemnifying  Party in full for all reasonable  costs and expenses
         incurred by the Indemnifying  Party in connection with such litigation.
         The Indemnifying  Party may retain separate counsel to represent it in,
         but  not  control,   any  defense  or  settlement   controlled  by  the
         Indemnified  Party pursuant to this clause (ii),  and the  Indemnifying
         Party  will  bear its own  costs  and  expenses  with  respect  to such
         participation.

            (iii) If the Indemnifying  Party notifies the Indemnified Party that
         it does not dispute its liability to the Indemnified Party with respect
         to the Third  Party Claim  under  Section  10.01 or fails to notify the
         Indemnified  Party within the Dispute Period  whether the  Indemnifying
         Party disputes its liability to the  Indemnified  Party with respect to
         such Third Party  Claim,  the Adverse  Consequences  arising  from such
         Third  Party  Claim  will be  conclusively  deemed a  liability  of the
         Indemnifying Party under Section 10.01 and the Indemnifying Party shall
         pay the amount of such Adverse Consequences to the Indemnified Party on
         demand following the final  determination  thereof. If the Indemnifying
         Party has timely disputed its liability with respect to such claim, the
         Indemnifying Party and the Indemnified Party will proceed in good faith
         to negotiate a resolution of such dispute,  and if not resolved through
         negotiations  within  the  Resolution  Period,  such  dispute  shall be
         resolved by litigation in a court of competent jurisdiction.

     (b) In the event any  Indemnified  Party should have a claim under  Section
10.01 against any Indemnifying  Party that does not involve a Third Party Claim,
the  Indemnified  Party  shall  deliver  an  Indemnity  Notice  with  reasonable
promptness to the  Indemnifying  Party. If the  Indemnifying  Party notifies the
Indemnified Party that it does not dispute the claim described in such Indemnity
Notice or fails to notify  the  Indemnified  Party  within  the  Dispute  Period
whether the  Indemnifying  Party disputes the claim  described in such Indemnity
Notice,  the  Adverse  Consequences  arising  from the claim  specified  in such
Indemnity  Notice will be  conclusively  deemed a liability of the  Indemnifying
Party under  Section  10.01 and the  Indemnifying  Party shall pay the amount of
such Adverse Consequences to the Indemnified Party on demand following the final
determination  thereof.  If the  Indemnifying  Party  has  timely  disputed  its
liability with respect to such claim, the Indemnifying Party and the Indemnified
Party will proceed in good faith to negotiate a resolution of such dispute,  and
if not resolved through  negotiations within the Resolution Period, such dispute
shall be resolved by litigation in a court of competent jurisdiction.

     (c) In the event of any claim for indemnity under this Article X, Purchaser
agrees to give Seller and its Representatives reasonable access to the Books and
Records and employees of each Company and the Subsidiary in connection  with the
matters  for which  indemnification  is sought to the extent  Seller  reasonably
deems necessary in connection with its rights and obligations under this Article
X.

10.03  Exclusivity.  After the  Closing,  to the extent  permitted  by Law,  the
indemnities  set forth in this  Article  X shall be the  exclusive  remedies  of
Purchaser and Seller and their respective officers, directors, employees, agents
and Affiliates for any  misrepresentation,  breach of warranty or nonfulfillment
or failure to be performed of any  representation or warranty  contained in this
Agreement,  and the  parties  shall  not be  entitled  to a  rescission  of this
Agreement  or to any  further  indemnification  rights or  claims of any  nature
whatsoever in respect thereof, all of which the parties hereto hereby waive.

                                   ARTICLE XI

                                   TERMINATION

prohibiting  or  making  illegal  the  consummation  of any of the  transactions
contemplated by this Agreement,  upon notification of the non-terminating  party
by the terminating party;

Agreement on the part of the other party,  which breach  either (i) is not cured
with fifteen (15) days following  written notice by the terminating party to the
party  committing such breach,  or (ii) by its nature,  cannot be cured prior to
April 30, 2001; or

     (d)  at any  time  after  April  30,  2001  by  Seller  or  Purchaser  upon
notification  of the  non-terminating  party  by the  terminating  party  if the
Closing  shall not have  occurred  on or before  such date and such  failure  to
consummate is not caused by a breach of this Agreement by the terminating party.

11.02 Effect of Termination. If this Agreement is validly terminated pursuant to
Section 11.01,  this  Agreement  will forthwith  become null and void, and there
will be no liability or obligation on the part of Seller or Purchaser (or any of
their respective officers, directors, employees, agents or other representatives
or  Affiliates),  except (i) that the  provisions  with  respect to  expenses in
Section  13.03 and  confidentiality  in  Section  13.05 will  continue  to apply
following any such  termination,  and (ii) that nothing  contained  herein shall
relieve  any  party   hereto   from   liability   for  willful   breach  of  its
representations,   warranties,   covenants  or  agreements   contained  in  this
Agreement.

     business for periods ending on or prior to the Closing Date.

     Assumed Liabilities. On the Closing Date, Buyer shall deliver to Seller the

          (b) all  liabilities  in  respect  of Taxes for which  Buyer is liable
     pursuant to Section 7.10;

          (c) all ongoing  reclamation under existing surface mining permits and

          (e) accounts  payable,  in an amount not to exceed  $25,000  (unless a
     greater  amount is approved by Buyer),  incurred in the Ordinary  Course of
     Business for  personal  property  that is not covered by the Balance  Sheet
     item "Materials and Supplies" ordered for the Business prior to Closing but
     not received until after the Closing.

          All of the  foregoing  liabilities  and  obligations  to be assumed by
     Buyer hereunder (excluding any Excluded Liabilities) are referred to herein
     as the "Assumed Liabilities."

     Excluded  Liabilities.  Buyer  shall  not  assume or be  obligated  to pay,
perform, or otherwise discharge any liability or obligation of Seller, direct or
indirect,  known or unknown,  absolute or contingent,  not expressly  assumed by
Buyer  pursuant  to the  Instrument  of  Assumption  (all such  liabilities  and
obligations  not being assumed  being herein called the "Excluded  Liabilities")
and, none of the  following  shall be Assumed  Liabilities  for purposes of this
Agreement,  and Seller shall pay,  perform,  or otherwise  discharge  all of the
following:

     (a) any  liabilities or  obligations,  recorded or unrecorded,  related to,
associated  with,  or arising out of the period prior to the Closing Date (other
than the  liabilities  and  obligations of Seller  incurred prior to the Closing
Date to perform those  obligations  under the Purchased  Contracts to be paid or
performed  after  the  Closing  Date,  except in each  case to the  extent  such
liabilities and obligations,  but for a breach or default by Seller,  would have
been paid, performed, or otherwise discharged on or prior to the Closing Date or
to the extent the same arise out of any such breach or default);

     (b) all  liabilities  and  obligations  under Section 15.6  ("Extended  Job
Opportunities")  of the IUOE  Agreement  and under Section 4.12  ("Extended  Job
Opportunities") of the UMWA Agreement;

     (c) any liabilities in respect of Taxes for which Seller is liable pursuant
to Section 7.10;

     (d) any  intercompany  payables and other  liabilities  or  obligations  of
Seller or any of its  Affiliates  (and for this purpose the Coal Sale  Contracts
and any CCB Disposal  Agreements  with or pertaining to the Coyote,  Heskett and
Lewis & Clark plants, shall not be deemed to be intercompany obligations);

     (e) any costs and expenses  incurred by Seller  incident to its negotiation
and  preparation of this Agreement and its  performance  and compliance with the
agreements and conditions contained herein,  including audit and accounting fees
and the fees of RMG;

     (f) any liabilities or obligations in respect of any Excluded Assets; and

     (g) any  liabilities or obligations in respect of the claims or proceedings

     2.5  Nonassignable   Contracts,   Permits,  and  Leases.  If  any  permits,
contracts,  or leases set forth on the  Schedules and required by Section 2.1 to
be transferred to Buyer are not by their  respective  terms  assignable,  Seller
agrees to use commercially reasonable efforts promptly to obtain, or cause to be
obtained,  any  written  consents  necessary  to convey to the Buyer the benefit
thereof, it being understood that such commercially reasonable efforts shall not
include any  requirement to remain  secondarily  liable with respect to any such
permits, contracts, or leases. Buyer shall cooperate with Seller, in such manner
as may  be  reasonably  requested  in  connection  therewith,  including  active
participation in visits to and meetings,  discussions, and negotiations with all
persons or entities  with the  authority  to grant or withhold  consent.  To the
extent  that any such  consents  cannot be  obtained,  Seller and Buyer will use
commercially  reasonable efforts to take such actions as may be possible without
violation or breach of any such nonassignable permits,  contracts,  or leases to
effectively  grant the Buyer the economic benefits of, and impose upon the Buyer
the economic burdens of such permits, contracts, and leases.


                                    ARTICLE 3

                                 PURCHASE PRICE

     Purchase Price. Subject to the terms and conditions of this Agreement,  and
in reliance on the representations,  warranties, undertakings, and agreements of
Seller made hereunder, and in consideration of such sale, conveyance,  transfer,
assignment, and delivery, Buyer agrees (a) to pay to Seller $28,830,000, subject
to adjustment pursuant to Section 3.3 (as adjusted,  the "Purchase Price"),  and
to undertake,  assume,  and agree to perform and  otherwise  pay,  satisfy,  and
discharge in accordance with their  respective  terms, and to indemnify and hold
Seller  harmless  with  respect  to,  and only  with  respect  to,  the  Assumed
Liabilities.  On the Closing Date, Buyer shall pay Seller  $28,830,000 minus the
Estimated  Employee Benefit  Adjustment Amount (the amount so paid, the "Closing
Date  Payment") in immediately  available  funds by wire transfer to the account
specified in Schedule  4.2. The Estimated  Employee  Benefit  Adjustment  Amount
shall be $2,300,000, which is an amount that has been estimated in good faith by
the parties based on a preliminary  report from Towers,  Perrin  estimating  the
Employee Benefit Adjustment Amount.

     3.2   Allocation  of  Purchase   Price.   Within  60  days   following  the
determination  of the  Purchase  Price  pursuant  to Section  3.3,  Buyer  shall
allocate the Purchase Price (together with the liabilities assumed hereunder and
other relevant items) among the Purchased  Assets based on the fair market value
of such assets, as determined by an independent  appraisal thereof.  Buyer shall
pay for such appraisal. Buyer shall notify Seller of its allocation.  Seller and
Buyer each agrees that, to the extent permitted by applicable law, it will adopt
and utilize the amounts  allocated to each asset or class of assets for purposes
of all  federal,  state,  and other  income Tax returns or reports of any nature
filed by it and  that it will not  voluntarily  take any  position  inconsistent
therewith upon examination of any such Tax returns or reports,  in any claim for
refund,  in any  litigation,  or  otherwise  with respect to such Tax returns or
reports.  Notwithstanding any other provisions of this Agreement,  the foregoing
agreement shall survive the Closing Date.

     3.3  Post-Closing  Adjustment.   (a)  Preparation  of  Preliminary  Closing
Statement.  (1) As soon as reasonably  possible  after the Closing Date (but not
later  than  120  days   thereafter),   Buyer  will  prepare  a  statement  (the
"Preliminary  Closing  Statement"),  which shall show (A) the  Employee  Benefit
Adjustment  Amount and (B) for the Business as of the Closing Date,  the Balance
Sheet Adjustment  Items.  Buyer shall deliver the Preliminary  Closing Statement
and a copy of the Towers,  Perrin  Report to Seller no later than 125 days after
the Closing Date.

               (2) The Balance Sheet  Adjustment Items shall consist of (and the
          term "Balance Sheet Adjustment  Items" shall mean) the following:  (A)
          Current Assets:  Inventories:  Coal, and (B) Current Assets: Materials
          and Supplies and (C) Current Assets: Deferred Costs: Mine Stripping.

               (3) With respect to the Employee Benefit Adjustment Amount,  such
          amount  shall be  determined  as  specified  in Section  7.3(c).  With
          respect to the Balance Sheet Adjustment Items, the Preliminary Closing
          Statement and the Final Closing  Statement shall,  except as set forth
          on  Exhibit C, be  prepared  in  accordance  with  generally  accepted
          accounting  principles ("GAAP") on a basis consistent with the Balance
          Sheet and shall set forth the value of each such item (the "Net  Asset
          Value").

          (b) Review of Preliminary  Closing Statement.  The Preliminary Closing
     Statement  shall be binding and conclusive  upon,  and deemed  accepted by,
     Seller unless Seller shall have notified Buyer in writing of any objections
     thereto  consistent  with the provisions of this Section 3.3 within 30 days
     after  receipt  thereof.  The written  notice  under this Section 3.3 shall
     specify in reasonable detail each item on the Preliminary Closing Statement
     that Seller disputes and a summary of Seller's reasons for such dispute.

          (c)  Disputes.  Disputes  between  Buyer and  Seller  relating  to the
     Preliminary  Closing  Statement  that  cannot be resolved by them within 30
     days after receipt by Buyer of the notice referred to in Section 3.3(b) may
     be  referred no later than 45 days after such  receipt for  decision at the
     insistence   of  either   party  to   Pricewaterhouse   Coopers   LLP.   If
     Pricewaterhouse  Coopers  LLP is  unavailable,  then,  within 60 days after
     receipt by Buyer of the notice  referred  to in Section  3.3(b),  Buyer and
     Seller  shall  select at random a "Big 5"  accounting  firm other than KPMG
     LLP, Arthur Andersen LLP, and Pricewaterhouse Coopers LLP.  Pricewaterhouse
     Coopers  LLP  or the  independent  accounting  firm  randomly  selected  is
     referred to herein as the  "Auditor."  Prior to referring the matter to the
     Auditor,  the parties  shall agree on the  procedures to be followed by the
     Auditor  (including  procedures  with regard to  presentation of evidence).
     Such procedures shall not alter the accounting practices,  principles,  and
     policies to be applied to the Preliminary Closing Statement, which shall be
     those  required  by Section  3.3(a)(3).  If the parties are unable to agree
     upon procedures  before the end of 30 days after referral of the dispute to
     the Auditor,  the Auditor shall establish such procedures giving due regard
     to  the   intention  of  the  parties  to  resolve   disputes  as  quickly,
     efficiently,  and  inexpensively as possible,  which procedures may be, but
     need not be, those proposed by either party.  The parties shall then submit
     evidence in accordance  with the  procedures  established,  and the Auditor
     shall decide the dispute in accordance therewith. The Auditor's decision on
     any matter  referred  to it shall be final and binding on Seller and Buyer.
     The fee of the  Auditor  shall  be  borne  by  Seller  and  Buyer  in equal
     portions.

          (d) Final Closing Statement.  The Preliminary  Closing Statement shall
     become  final and  binding  upon the  parties  upon the  earlier of (1) the
     failure  by Seller to object  thereto  within the  period  permitted  under
     Section  3.3(b),  (2) the  agreement  between Buyer and Seller with respect
     thereto,  or (3) the  decision by the Auditor  with respect to any disputes
     under  Section  3.3(c).  The  Preliminary  Closing  Statement,  as adjusted
     pursuant to the  agreement of the parties or decision of the Auditor,  when
     final and binding is referred to herein as the "Final Closing Statement."

          (e) Adjustment to the Purchase Price. As soon as practicable  (but not
     more than five Business Days) after the  determination  and delivery of the
     Final  Closing  Statement  in  accordance  with this  Section  3.3: (1) the
     Purchase Price shall be reduced by the Employee Benefit  Adjustment Amount,
     (2) the Purchase Price shall be adjusted as  contemplated in Section 7.2(b)
     to reflect Seller's capital  expenditures in 2000, and (3) if the Net Asset
     Value of the Balance Sheet Adjustment  Items, as of the Closing Date and as
     reflected on the Final Closing  Statement,  exceeds the  Reference  Amount,
     then the  Purchase  Price shall be  increased by the amount of such excess,
     and (4) if the Reference  Amount exceeds the Net Asset Value of the Balance
     Sheet  Adjustment  Items,  as of the Closing  Date and as  reflected on the
     Final Closing  Statement,  then the Purchase  Price shall be reduced by the
     amount of such excess.  If the Purchase  Price, as determined in accordance
     with the immediately preceding sentence,  exceeds the Closing Date Payment,
     then Buyer shall pay Seller the amount of such  excess,  and if the Closing
     Date Payment  exceeds the Purchase  Price, as determined in accordance with
     the immediately preceding sentence,  then Seller shall pay Buyer the amount
     of such excess.  Buyer and Seller  shall ensure that all such  payments are
     made  via  wire   transfer   within  ten  (10)   Business  Days  after  the
     determination  and delivery of the Final  Closing  Statement in  accordance
     with this Section 3.3.

          (f)  Interest.  All  payments  required  to be made  pursuant  to this
     Section  3.3 shall be made with simple  interest  thereon at the prime rate
     plus one percentage point on the Closing Date (the  "Applicable  Rate") and
     accruing from the Closing Date to the date of payment.

     Seller represents and warrants to Buyer that, and agrees as follows:

     Organization. Seller is a corporation duly organized, validly existing, and

power and  authority to carry on its business as now being  conducted and to own
its  properties.  Seller is duly licensed or qualified and in good standing as a

Business  as now  conducted.  Seller  has  heretofore  made  available  to Buyer
complete and correct copies of its certificate of  incorporation  and by-laws as
currently in effect.


     5.2 Corporate  Authority.  Seller has full corporate power and authority to
enter into this Agreement and the Seller Ancillary  Agreements and to consummate
the transactions  contemplated hereby and thereby.  Upon receipt of the approval
of Seller's  Board of Directors,  this Agreement will be, and each of the Seller
Ancillary Agreements will be as of the Closing Date, duly executed and delivered

Buyer)  this  Agreement  will  constitute,  and  each  of the  Seller  Ancillary
Agreements  when executed and delivered by Seller will  constitute,  a valid and
binding obligation of Seller,  enforceable in accordance with its terms,  except
as such enforceability may be limited by bankruptcy, insolvency, reorganization,
or similar laws affecting  creditors'  rights generally or by general  equitable
principles.

     Subsidiaries and  Investments.  Seller does not operate the Business or any
portion thereof through  Subsidiaries,  is not a member of any limited liability
company  relevant  to  the  Business,  and  is  not a  general  partner  in  any

          (a) any Requirement of Laws,

          (b) any certificate of incorporation or by-laws,

          (c) any mortgage, deed of trust, lease, note, contract,  shareholders'
     agreement, bond, indenture, other instrument or agreement, license, permit,

          (d) any judgment,  order,  writ,  injunction,  or decree of any court,
     Governmental Body, or arbitrator,

that would prevent or be violated by or that would result in the creation of any
Encumbrance  as a result of, or under which there would be a default or right of
termination as a result of, the execution,  delivery,  and performance by Seller
of this Agreement and the Seller  Ancillary  Agreements and the  consummation of
the  transactions  contemplated  hereby  and  thereby.  Except as  disclosed  in
Schedule 5.4, no consent, approval, or authorization of or declaration or filing
with any Person is required for the valid execution,  delivery,  and performance
by Seller of this Agreement and by Seller of the Seller Ancillary Agreements and
the consummation of the transactions contemplated hereby and thereby.

     Litigation.  (a)  Except as  disclosed  in  Schedule  5.5,  there is (1) no
outstanding consent, order, judgment, injunction, award, or decree of any court,
Governmental Body, or arbitration  tribunal against or involving Seller relating
to the Business or this  Agreement,  or against or involving the Business or any
of the assets or properties of the Business,  and (2) no action,  suit, dispute,
or  governmental,  administrative,  arbitration,  or  regulatory  proceeding  or
investigation  pending or, to the  Knowledge  of Seller,  threatened  against or
involving  Seller relating to the Business or this Agreement,  or pending or, to
the Knowledge of Seller,  threatened against or involving the Business or any of
the assets or properties of the Business (collectively, "Proceedings").

          (b) Except as  disclosed  in  Schedule  5.5,  Seller has not  received
     written notice of any actions, suits, or legal, administrative, or arbitral
     proceedings  pending to which Seller is a party,  or written  notice of any
     threatened   actions,   suits,  or  legal,   administrative,   or  arbitral
     proceedings  against Seller that questions the validity of this  Agreement,
     or of the transactions contemplated hereby, or of any action taken or to be
     taken by Seller in connection with this Agreement.

convey to buyer at the Closing all of the assets of the Business (other than the
Excluded Assets), all of properties,  assets, and other rights of Seller used in
the  Business,  and all of the  Purchased  Assets,  including  such  title as is
specified in Sections 5.8 and 5.9.

     5.7 Purchased Assets.  Except for Seller's Bismarck office and the Excluded

(showing the grantor, legal description,  and recording  information).  Schedule
2.1(b) sets forth a list and a brief  description  of each In Lease (showing the
current  lessor and lessee,  execution  date,  annual rental,  expiration  date,
renewal and  purchase  options,  if any, and the legal  description  of the Real
Property  covered by each such In Lease).  Schedule  2.1(d) sets forth a list of
each Out Lease  showing  the names of the  lessor and lessee and the date of the
execution of each such lease.  Seller shall provide such additional  information
regarding  the Out  Leases  as Buyer may  reasonably  request.  Seller  has made
available  to  Buyer  complete  and  correct  copies  of each  and  every of the
following,  if any,  in the  possession  of  Seller:  (1) title  reports,  title
binders,  survey  documents,  and data  affording  information  or opinions with
respect to,  certifying  to, or  evidencing  the extent,  current  title,  title
history, title marketability,  use, possession,  restriction,  or regulation, if
any  (governmental  or otherwise),  and compliance with applicable  laws, of the
Real Property;  (2) deed or  title-holding  or trust  agreements,  if any, under
which any of the Real  Property may have been  conveyed to Seller or under which
the same may be held for the  benefit of  Seller;  and (3)  leases  included  as
Purchased Assets and all documents  relating  thereto,  including any amendments
thereto and any assignment thereof.

          (b) With  respect to Real  Property  which is a part of the  Purchased
     Assets,  the Seller has good and valid fee or leasehold  title, as the case
     may be,  to all such  Real  Property,  in each  case  free and clear of all
     liens,  claims,  charges,  options,  encumbrances,  mortgages,  pledges  or
     security interests ("Liens"),  except for Permitted  Encumbrances,  and has
     the exclusive right to mine all coal therein.

          (c)  Seller  has  not  received  any  notice  of  any   appropriation,
     condemnation,  or like  proceeding,  or of any violation of any  applicable
     zoning law,  regulation,  or other law, order,  regulation,  or requirement
     relating to or affecting the Real Property, and no such proceeding has been
     threatened or commenced.

          (d) All of the In Leases  which are part of the  Purchased  Assets are

                              additional agreements

     7.1  Earn-out.  In addition to the Purchase  Price,  Buyer shall pay Seller
$0.5190 per ton, adjusted October 1, 2001 and annually thereafter for changes in
the Gross Domestic  Product-Implicit  Price Deflator  ("GDP-IPD"),  on the first
2,535,700  tons of coal  mined  and  shipped  by Buyer  (a) to the  Holly  Sugar
refinery at Sidney,  Montana after August 31, 2003; and (b) to the Lewis & Clark
power plant at Sidney, Montana after December 31, 2002; provided,  however, that
these  amounts  shall be  payable by Buyer only upon and in the event of payment
for the related coal by the customer. These earn-out amounts shall be calculated
and paid as described  in Schedule  7.1.  Buyer shall pay all earn-out  sums due
Seller on a quarterly  basis.  In the event that the GDP-IPD  index ceases to be
published,  the inflation index most similar to the GDP-IPD shall be substituted
in its place. For the avoidance of doubt, under no circumstances shall Buyer pay
Seller more than  $1,316,028.30  (as such sum may be adjusted for changes in the
GDP-IDP) pursuant to this Section 7.1.

     7.2 Conduct of Business  Prior to the Closing  Date.  Seller  agrees  that,
between  the date  hereof and the  earlier of the  Terminal  Date or the Closing
Date:

          (a) Except as  contemplated  by this Agreement or permitted by written
     consent of Buyer,  Seller shall  operate the Business  only in the Ordinary
     Course of Business and shall not:

               (1) take any action of the nature  referred  to in Section  5.20,
          except as permitted therein;

               (2) change the Business's banking or safe deposit arrangements;

               (3) change Seller's  certificate of  incorporation  or by-laws in
          any manner that would impair this transaction;

               (4) make or  agree  to any  purchase  or  other  commitment  with
          respect to the Business exceeding $50,000 in value;

               (5)  assume  any  obligation  that is more than a  month-to-month
          commitment or extend or modify any Coal Sale Contract except the Holly
          Sugar Coal Agreement; or

               (6)  deposit  or allow to be  deposited  in any pit at the Savage
          Mine  any  material,  that  would  interfere  with the  resumption  or
          continuation of the mining of coal from any such pit.

     (b) The phrase  "Ordinary  Course of  Business"  shall  have its  customary
meaning,  including without limitation and as modified by the following:  Seller
shall, between the date hereof and the Closing Date: (1) continue to operate the
Mines consistent with good business  practices in compliance with all applicable
contracts and other  obligations,  and all Requirements of Laws,  incurring only
ordinary and necessary  business  expenses  consistent  with past  practices for
Mines,  (2)  maintain  and  preserve  the  goodwill,   business   relationships,
Governmental  Permits,  and  other  rights  of the  Business,  (3)  keep all the
Purchased  Assets in good  working  order and repair  (reasonable  wear and tear
excepted), (4) continue to make capital expenditures until the Closing Date such
that as of the Closing  Date Seller  shall have spent a pro rata  portion of its
total  year  2000  capital  budget of  $2,464,000  (with  any  difference  to be
reconciled by means of a purchase price adjustment),  (5) not transfer,  sell or
dispose of, or contract to transfer,  sell or dispose of, any Purchased  Assets,
except in the ordinary course of business,  consistent with past practices,  and
(6) not accelerate the collection of or sell or assign any accounts  receivable,
or decelerate the payment of accounts  payable,  except in order to conform with
past practices.

     (c) Seller shall preserve the organization of the Business intact and shall
use its  reasonable  efforts  to keep  available  to Buyer the  services  of the
present  employees of the Business and to preserve for Buyer the goodwill of the
Business's  suppliers,  customers,  distributors,  coal transporters,  and sales
representatives, if any, and others having relations with the Business.

     (d) Seller shall  maintain in force the insurance  policies  referred to in
Schedule 5.22 or insurance policies providing the same or substantially  similar
coverage;  provided,  however,  that  Seller  will  notify  Buyer  prior  to the
expiration of any of such insurance policies.

     (e) Except as  contemplated by this Agreement  (including  Sections 7.3 and
7.4) or permitted by written  consent of Buyer,  no plan,  fund, or  arrangement
disclosed or required to be  disclosed in Schedule  5.16(a) as it relates to the
Business and Transferred Employees has been or will be:

          (1) terminated by Seller or any member of the Controlled Group;

          (2) amended (except as expressly  required by law) in any manner which
     would directly or indirectly increase the benefits accrued, or which may be
     accrued, by any participant thereunder; or

          (3) amended in any manner which would materially  increase the cost to
     Buyer of maintaining such plan, fund, or arrangement.

          (f) Seller shall  continue to reclaim the Bravo pit at the Beulah Mine
     in the Ordinary  Course of Business,  and Seller's  personnel and equipment
     shall  continue to be deployed in support of  reclamation  of the Bravo pit
     when such  personnel and  equipment are not necessary to support  mining or
     reclamation  at the active pits. At the Closing Date,  all Seller's  active
     pits  shall  be in  contemporaneous  reclamation,  within  the  meaning  of
     applicable Requirements of Laws.

     7.3 Employee Matters. Buyer shall offer employment to those individuals set
forth on Schedule 7.3  commencing as of the Closing Date.  All such  individuals
who accept offers of  employment  with Buyer as of the Closing shall be referred
to herein as "Transferred Employees".  However, as to employees who are disabled
or on sick leave on the  Closing  Date,  Seller  shall  indemnify  Buyer for all
Losses Buyer incurs in excess of $50,000 in the aggregate  attributable  to such
employees  until such  employees  return to work.  Seller  shall assist Buyer in
effecting the Transferred Employees' change of employment as of the Closing Date
in an orderly fashion.

          (b) Buyer shall provide to the  Transferred  Employees who are covered
     by the UMWA  Agreement  or the IUOE  Agreement  a  post-retirement  medical
     benefit  substantially  comparable to the  post-retirement  medical benefit
     Seller  provides to such Persons as of the date hereof until the expiration
     date of such Agreements.  As to the Transferred Employees who are salaried,
     Buyer for two years from the Closing  Date,  shall  provide such  employees
     with medical, post-retirement medical, dental, vacation, severance, defined
     contribution   plan,  and  other  benefits  that  are,  in  the  aggregate,
     substantially comparable to the benefits Seller provides to such Persons at
     the date hereof.

          (c) To compensate Buyer for the cost of providing any benefits accrued
     by Transferred  Employees prior to the Closing Date, Seller shall pay Buyer
     the present value or actuarial  value,  as applicable,  of vested  benefits
     accrued as of the Closing  Date for  vacation,  bonus,  medical  (including
     post-retirement  medical or other nonqualified retirement benefit) or other
     compensation or benefit arrangement, plan, or policy of Seller. The present
     actuarial value of such benefits,  other than accrued vacation and bonuses,
     shall be determined by the firm of Towers,  Perrin, Forster & Crosby, which
     shall compute the present  value of such  benefits in accordance  with GAAP
     (using a  discount  rate of 7.75%  (or such  other  rate as  agreed by Bill
     Williamson of Towers, Perrin,  Forster, & Crosby,  Philadelphia office, and
     Thomas Holm of Towers, Perrin, Forster & Crosby,  Minneapolis office, based
     on the change in the  Moody's Aa  Corporate  Bond  Yield  between  the date
     hereof and the  Closing  Date))  equal to the  accumulated  post-retirement
     benefit  obligation  on the  Closing  Date,  and  shall be set  forth in an
     actuarial report of such firm (the "Towers,  Perrin  Report").  Buyer shall
     thereafter  be liable for providing  such benefits and for all  liabilities
     associated  with such  benefits.  The value of such benefits is referred to
     elsewhere in this Agreement as the "Employee Benefit Adjustment Amount." As
     provided in Section 3.3(e), the Employee Benefit Adjustment Amount shall be
     deducted from the Purchase Price payable pursuant to Section 3.1. Except as
     provided in this Section 7.3 and in Section 7.4, Buyer shall not assume any
     assets or liabilities or any other obligation with respect to any vacation,
     bonus,  medical  (including  post-retirement  medical or other nonqualified
     retirement  benefit)  or other  compensation  or benefit  arrangement  with
     respect to any current,  former,  or retired employee of Seller,  including
     any Transferred  Employee,  and Seller retains all liabilities with respect
     to all such benefits.

          (d) Each Transferred Employee shall become fully vested in his accrued
     benefit in each tax qualified  plan  maintained by Seller or the Controlled
     Group  ("Seller's  Qualified  Plans")  calculated  as of the Closing  Date.
     Seller  agrees that it will take such steps as are  necessary  to carry out
     the obligations of the first sentence of this paragraph and, as promptly as
     practicable, shall supply to Buyer evidence of the actions taken and copies
     of the operative  documents.  Buyer agrees that it shall confirm, as of the
     Closing Date, the names of all Transferred Employees.

     7.4 Certain Employee Benefit Plan Matters.  Seller  represents and warrants
(a) that it maintains  two defined  benefit  plans,  one for salaried  employees
("Existing  Salaried  Employees' Plan") and one for hourly employees  ("Existing
Hourly Employees' Plan"); and (b) that each of the Existing Salaried  Employees'
Plan and the Existing Hourly Employees' Plan is fully funded. After the Closing,
Buyer shall create two new plans, one for the hourly employees Buyer is required
to hire pursuant to Section 7.3 ("New Hourly  Employees'  Plan") and one for the
salaried  employees  Buyer is  required  to hire  pursuant  to Section 7.3 ("New
Salaried  Employees' Plan"),  and Seller shall spin off the benefit  liabilities
for the relevant  employees to each such plan.  Seller shall transfer to the New
Hourly  Employees'  Plan  assets  equal to the  aggregate  present  value of the
accrued benefits under the Existing Hourly  Employees' Plan  attributable to the
hourly  employees Buyer is required to hire pursuant to Section 7.3,  determined
on a  termination  basis as of the Closing  Date (within the meaning of Treasury
Regulation Section  1.414(l)-1(b)(5)  and based on the "expected retirement age"
as  defined  in PBGC  regulations  and the PBGC  termination  interest  rate for
annuity  purposes  (currently such interest rate effective for September 2000 as
published by the PBGC is 7.00% for the next 25 years and 6.25%  thereafter)  for
pension  plans as of the  Closing  Date),  as  certified  by the firm of Towers,
Perrin,  Forster, & Crosby (and taking into account a fifty percent cost sharing
of any changes in benefits  (except  those  related to a mine shutdown or twenty
and out  provision)  effected or to be effected by the  Assumption  Agreements).
Seller shall  transfer to the New Salaried  Employees'  Plan assets equal to the
aggregate  present  value of the accrued  benefits  under the Existing  Salaried
Employees' Plan attributable to the salaried employees Buyer is required to hire
pursuant to Section 7.3,  determined  on a  termination  basis as of the Closing
Date (within the meaning of Treasury  Regulation  Section  1.414(l)-1(b)(5)  and
based on the "expected  retirement  age" as defined in PBGC  regulations and the
PBGC  termination  interest rate for annuity  purposes  (currently such interest
rate effective for September 2000 as published by the PBGC is 7.00% for the next
25 years and 6.25%  thereafter)  for pension plans as of the Closing  Date),  as
certified by the firm of Towers, Perrin, Forster, & Crosby.

     7.5  Expenses.  Buyer and Seller shall bear its own expenses in  connection
with this Agreement and its performance thereof.

     7.6 Access to Information and Confidentiality. Seller agrees that Buyer may
conduct such  reasonable  investigation  with respect to the business,  business
prospects, assets, liabilities (contingent or otherwise), results of operations,
employees,  and  financial  condition  of the  Business as will permit  Buyer to
evaluate its interest in the transactions  contemplated by this Agreement.  Each
of Seller and Buyer will hold and will cause their respective representatives to
hold  in  strict  confidence,  unless  compelled  to  disclose  by  judicial  or
administrative process, or, in the opinion of its counsel, by other Requirements
of Laws,  all  documents  and  information  concerning  Seller  or the  Business
furnished to Buyer and all documents and information  concerning Buyer furnished
to Seller in connection  with the  transactions  contemplated  by this Agreement
(except  to the  extent  that  such  information  can be shown to have  been (a)
previously  known  by Buyer  prior to its  disclosure  to Buyer by  Seller,  (b)
previously  known by Seller prior to its  disclosure to Seller by Buyer,  (c) in
the  public  domain  through  no fault of either  Seller or Buyer,  or (d) later
lawfully  acquired  by either  Seller or Buyer from other  sources  that are not
under an  obligation of  confidentiality)  and will not release or disclose such
information to any other Person, except in connection with this Agreement to its
lenders,  auditors,  attorneys,  financial  advisors and other  consultants  and
advisors.

     7.7 No Solicitation. Unless and until termination occurs in accordance with
Article 12, Seller shall not, and shall direct each of its affiliates, officers,
employees,  representatives or agents not to, directly or indirectly, encourage,
solicit, initiate, or engage in discussions or negotiations with, or provide any
non-public   information  to,  any  Person  concerning  any  merger,   sales  of
substantial  assets,  sales of shares of capital stock, or similar  transactions
involving the Business or enter into any agreement with respect thereto.  Seller
will  promptly  communicate  to Buyer  the  terms of any  proposal  which it may
receive in respect of all such transactions prohibited by the foregoing.

     7.8 Press Releases. Except as required by law or stock exchange regulation,
any public announcements regarding the transactions contemplated hereby shall be
made only with the  mutual  consent of Seller and  Buyer.  This  covenant  shall
terminate on the Termination Date or the Closing Date, whichever first occurs.

     7.9  Transitional  Assistance.  For a period of up to 90 days following the
Closing  Date,  Seller  shall  cooperate  with and assist  Buyer in the  orderly
transfer of the Business after the Closing Date. Such cooperation and assistance
shall  include  but not be limited to (a) the  physical  transfer  of any books,
records, and computer software of the Business with shipping costs to be paid by
Buyer;  (b) reasonable  access to and assistance  from  designated  employees of
Seller as approved by Nancy  Christenson;  and (c) such  transition  services as
Buyer may reasonably request.  At Buyer's request,  Seller shall assign Seller's
personnel to provide contract administration  services,  payroll services, human
relations  ("HR")  services,  and  information  technology  services  (all  such
services,  collectively,  the  "Transition  Services")  to Buyer for ninety days
following the Closing.  Buyer shall not be required to pay any additional fee or
charge for such  Transition  Services.  Seller is providing  these  transitional
services solely as an accommodation to Buyer. Buyer acknowledges and agrees that
these transitional services are for "processing" functions only, and it shall be
Buyer's sole  responsibility  to assure itself that all documents sent to Seller
for processing have had the  appropriate  levels of review and approval by Buyer
prior to receipt of Seller's  Bismarck office.  Should  processing errors occur,
Buyer shall have no legal recourse against Seller.

     7.10 Taxes. (a) Seller shall be liable for and shall pay all Taxes (whether
assessed or unassessed)  applicable to the Business and the Purchased Assets, in
each case  attributable  to periods (or portions  thereof) ending on or prior to
the Closing  Date.  Buyer  shall be liable for and shall pay all Taxes  (whether
assessed or unassessed)  applicable to the Business and the Purchased Assets, in
each case  attributable  to periods (or portions  thereof)  beginning  after the
Closing Date. For purposes of this paragraph  (a), any period  beginning  before
and ending after the Closing Date shall be treated as two partial  periods,  one
ending on the Closing Date and the other beginning after the Closing Date except
that  Taxes  (such as  property  Taxes)  imposed on a  periodic  basis  shall be
allocated on a daily basis.

          (b)  Notwithstanding  Section  7.10(a),  any sales Tax, use Tax,  real
     property  transfer  or gains Tax,  documentary  stamp Tax,  or similar  Tax
     attributable  to the sale or  transfer  of the  Purchased  Assets  shall be
     divided  equally  between  Seller and Buyer.  Buyer and Seller shall timely
     sign  and  deliver  such  certificates  or  forms  as may be  necessary  or
     appropriate to establish an exemption from (or otherwise reduce), or make a
     report with respect to, such Taxes.

          (c) Seller or Buyer,  as the case may be, shall provide  reimbursement
     for  any  Tax  paid  by  one  party  all  or a  portion  of  which  is  the
     responsibility  of the  other  party in  accordance  with the terms of this
     Section  7.10.  Within a  reasonable  time prior to the payment of any said
     Tax,  the party paying such Tax shall give notice to the other party of the
     Tax payable and the portion that is the  liability of each party,  although
     failure  to do so will not  relieve  the  other  party  from its  liability
     hereunder.

     7.11 Gascoyne. (a) If at any time prior to December 31, 2010 Seller intends
at any time to sell or  otherwise  transfer all or a portion of its coal reserve
interest in the  Gascoyne  mine  previously  operated by Seller  (including  all
related reserves,  facilities,  and real property  interests directly related to
the coal reserves)  ("Gascoyne") to any Person other than in connection with the
Development  Option,  Seller  shall comply with the  provisions  of this Section
7.11(a).  In the event Seller intends to accept a bona fide offer to purchase or
otherwise  transfer all or a portion of its  interest in Gascoyne,  Seller shall
give written notice (a "Sale Notice") to Buyer of such bona fide offer,  setting
forth the terms thereof.  Within thirty (30) days from the date Buyer receives a
Sale  Notice  from  Seller,  Buyer  shall  give to Seller a notice in writing (a
"Purchase  Notice")  irrevocably  committing  Buyer  to  acquire  or cause to be
acquired  from  Seller all (but not less than all) of the  interest  in Gascoyne
listed in the Sale  Notice on  substantially  the  terms  contained  in the Sale
Notice.  Seller shall be obligated to sell or otherwise transfer and Buyer shall
be  obligated  to acquire  such  interest in Gascoyne  pursuant to the terms set
forth in the Sale Notice.  If Buyer fails to provide a Purchase Notice to Seller
within such 30-day period,  Buyer's right of first refusal shall  terminate with
respect to the  interest  in  Gascoyne  specified  in the Sale Notice and Seller
shall be free to sell  such  interest  to the  person(s)  specified  in the Sale
Notice on terms and at a price not more  favorable to such  person(s)  than were
stated in such notice.

          (b) If, at any time prior to December 31, 2010, either Seller or Buyer
     determines that it wishes to develop the Gascoyne reserves, then that party
     (the  "Gascoyne  Initiator")  shall give written  notice to the other party
     (the  "Gascoyne  Responder").  If the  Gascoyne  Initiator  is Seller,  the
     Gascoyne  Initiator  shall offer the Gascoyne  Responder the opportunity to
     co-develop  the Gascoyne  reserves and shall share  equally in the monetary
     costs and benefits of doing so (the "Development  Option"). If the Gascoyne
     Initiator is Buyer,  then the Gascoyne  Initiator  shall offer the Gascoyne
     Responder  either (1) a 2% royalty override on the price of coal mined less
     production taxes at Gascoyne (the "Royalty  Option") or (2) the opportunity
     to co-develop the Gascoyne reserves and share equally in the monetary costs
     and benefits of doing so. The Gascoyne  Responder  may accept or reject any
     option  proposed  by the  Gascoyne  Initiator.  If the  Gascoyne  Responder
     selects either the Royalty  Option or the  Development  Option,  the option
     selected  by the  Gascoyne  Responder  shall be final and  binding  on both
     parties.  If the  Royalty  Option is  selected  and  Buyer is the  Gascoyne
     Initiator,   Seller  shall  take  all  commercially   reasonable  steps  to
     facilitate  Buyer's  development  of the Gascoyne site, and Buyer shall pay
     Seller  the  2%  royalty  override  in  consideration   therefor.   If  the
     Development  Option  is  selected,  the  parties  shall  take  commercially
     reasonable  steps to develop the Gascoyne  site and shall share  equally in
     the  monetary  costs and  benefits  of doing  so. If Buyer is the  Gascoyne
     Initiator and Seller  rejects both the Royalty  Option and the  Development
     Option,  Seller  shall  transfer  the  Gascoyne  reserves  to  Buyer  for a
     consideration of $1. If Seller is the Gascoyne  Initiator and Buyer rejects
     the Development Option, Buyer's rights under this Subsection (b) of Section
     7.11  shall  terminate.  The  right  to any  royalty  override  under  this
     Subsection  (b) of Section 7.11 shall survive the  termination or amendment
     of any lease for any of the Gascoyne reserves.

          (c) This  Agreement  does not obligate  Seller to continue to lease or
     maintain any coal  reserves at Gascoyne.  Seller shall provide Buyer with a
     list  showing the  expiration  date for each of the leases  relating to the
     Gascoyne  site,  and Seller and Buyer shall  update that list as  necessary
     from the Closing Date through December 31, 2010.

     7.12 Covenant Not to Compete.  From and after the Closing Date, and so long
as Buyer is party to a  contract  with  the  International  Union,  United  Mine
Workers of America,  neither Seller nor any affiliate of Seller will at any time
compete, directly or indirectly, with Buyer in the mining or sale of coal at any
location  within the  States of North  Dakota or  Montana  including  having any
direct or indirect  financial  interest in any enterprise  which engages in such
business or entering  into or seeking to enter into any  commitment to engage in
such business; provided, however, that this covenant shall not prohibit or limit
Seller's rights and obligations under Section 7.11.


     7.13 Phase I Environmental  Study. Seller shall arrange and pay for a Phase
I  environmental  study  conducted  according  to ASTM  standards  (the "Phase I
Environmental  Study")  of the  Business  and the Real  Property.  Seller  shall
deliver a copy of that study to Buyer.

     7.14  Further  Assurances.  At the  Closing and from time to time after the
Closing, (a) at the request of Buyer and without further  consideration,  Seller
shall  promptly  execute  and  deliver  to Buyer  such  certificates  and  other
instruments of sale, conveyance,  assignment,  and transfer, and take such other
action, as Buyer may reasonably request to sell, convey, assign, and transfer to
and vest in Buyer or to put Buyer in possession of the Purchased Assets, and (b)
at the request of Seller and without further consideration, Buyer shall promptly
execute  and  deliver  to Seller  such  certificates  and other  instruments  of
assumption, and take such other action, as may reasonably be requested by Seller
more  effectively  to  confirm  and  carry  out the  assumption  by Buyer of the
obligations of Seller assumed by Buyer pursuant to the Instrument of Assumption.

     7.15 Tax Free Exchange. It is the intent of Seller that this transaction be
part of a Tax Deferred Exchange  according to Section 1031 of the Code and Buyer
agrees  to  cooperate  in  executing   documentation  provided  by  an  exchange
accommodator  at no  expense to Buyer so long as it does not impair or limit any
of Seller's warranties,  representations, and agreements contained herein. Buyer
makes no  representations  or  warranties  as to whether this  transaction  will
constitute a tax free  exchange  under  Section 1031 of the Code nor shall Buyer
bear any liability if the IRS determines that this transaction is not a tax free
exchange.

          except that the indemnification by Buyer shall continue as to:

                    (1) the representations and warranties set forth in Sections
               6.1, 6.2, and 6.5, and the covenants and  agreements of Buyer set
               forth in Sections  10.2(a)(3) and 10.2(a)(4),  as to all of which

               such Loss and Expense in accordance with this Section 10.2.

     10.3 Notice of Indemnity Claims. (a) Any Buyer Group Member or Seller Group
Member (the "Indemnified Party") seeking indemnification hereunder shall give to
the party obligated to provide  indemnification  to such Indemnified  Party (the
"Indemnitor")  a notice (a "Claim Notice")  describing in reasonable  detail the
facts giving rise to any claim for  indemnification  hereunder and shall include
in such Claim Notice (if then known) the amount or the method of  computation of
the amount of such claim,  and a reference to the provision of this Agreement or
any other agreement,  document or instrument executed hereunder or in connection
herewith  upon  which  such  claim is based;  provided,  that a Claim  Notice in
respect of any  action at law or suit in equity by or against a third  Person as
to which indemnification will be sought shall be given promptly after the action
or suit is commenced;  and provided,  further,  that failure to give such notice
shall not relieve the  Indemnitor  of its  obligations  hereunder  except to the
extent it shall have been prejudiced by such failure.


          (b) After the giving of any Claim Notice pursuant  hereto,  the amount
     of  indemnification  to which an Indemnified  Party shall be entitled under
     this Article 10 shall be determined:  (1) by the written  agreement between
     the Indemnified Party and the Indemnitor; (2) by a final judgment or decree
     of any court of competent jurisdiction;  or (3) by any other means to which
     the  Indemnified  Party and the  Indemnitor  shall  agree.  The judgment or
     decree of a court shall be deemed  final when the time for appeal,  if any,
     shall have  expired and no appeal shall have been taken or when all appeals
     taken shall have been finally determined.  The Indemnified Party shall have
     the burden of proof in establishing the amount of Loss and Expense suffered
     by it.

     10.4 Third Person Claims.  (a) Subject to Section 10.4(b),  the Indemnified
Party  shall  have the right to  conduct  and  control,  through  counsel of its
choosing,  the defense,  compromise,  or  settlement  of any third Person claim,
action, or suit against such Indemnified Party as to which  indemnification will
be sought by any  Indemnified  Party from any Indemnitor  hereunder,  and in any
such case the  Indemnitor  shall  cooperate in  connection  therewith  and shall
furnish such records,  information,  and testimony and attend such  conferences,
discovery  proceedings,  hearings,  trials,  and  appeals  as may be  reasonably
requested by the Indemnified Party in connection therewith;  provided,  that the
Indemnitor may participate, through counsel chosen by it and at its own expense,
in the defense of any such claim,  action,  or suit as to which the  Indemnified
Party has so elected to conduct and control the defense  thereof;  and provided,
further,  that the Indemnified  Party shall not,  without the written consent of
the Indemnitor (which written consent shall not be unreasonably withheld),  pay,
compromise,  or settle any such  claim,  action,  or suit,  except  that no such
consent shall be required if,  following a written  request from the Indemnified
Party,  the  Indemnitor  shall  fail,  within 14 days  after the  making of such
request,  to acknowledge  and agree in writing that, if such claim,  action,  or
suit shall be adversely determined, such Indemnitor has an obligation to provide
indemnification hereunder to such Indemnified Party.

          (b) If any third Person claim, action, or suit against any Indemnified
     Party is solely for money damages or, where Seller is the Indemnitor,  will
     have no continuing effect in any material respects on the Purchased Assets,
     then the  Indemnitor  shall have the right to conduct and control,  through
     counsel of its choosing, the defense, compromise, or settlement of any such
     third Person claim,  action,  or suit against such Indemnified  Party as to
     which  indemnification  will be sought by any  Indemnified  Party  from any
     Indemnitor  hereunder  if the  Indemnitor  has  acknowledged  and agreed in
     writing that, if the same is adversely  determined,  the  Indemnitor has an
     obligation to provide  indemnification  to the Indemnified Party in respect
     thereof,  and in any such case the  Indemnified  Party shall  cooperate  in
     connection  therewith  and shall  furnish such  records,  information,  and
     testimony and attend such  conferences,  discovery  proceedings,  hearings,
     trials,  and appeals as may be  reasonably  requested by the  Indemnitor in
     connection therewith; provided, that the Indemnified Party may participate,
     through counsel chosen by it and at its own expense,  in the defense of any
     such claim,  action,  or suit as to which the  Indemnitor has so elected to
     conduct and control the defense thereof. Notwithstanding the foregoing, the
     Indemnified  Party shall have the right to pay,  settle,  or compromise any
     such claim, action, or suit;  provided,  that in such event the Indemnified
     Party shall waive any right to indemnity therefor hereunder.

     10.5 Environmental Indemnification and Limitation Thereof. (a) Seller shall
indemnify and hold harmless each Buyer Group Member from and against any and all
Loss or  Expense  incurred  by such  Buyer  Group  Member  as a  result  of,  in
connection with, or arising from:

          (1) any breach of any warranty or the inaccuracy of any representation
     of Seller set forth in Subsection (c) of Section 5.21, or any breach of any
     warranty or the inaccuracy of any representation in a certificate delivered
     by or on behalf of Seller that  repeats a  representation  or warranty  set
     forth in Subsection (c) of Section 5.21;

          (2) loss of life, injury to persons or property,  or damage to natural
     resources  caused by the  Release,  storage,  transportation,  treatment or
     generation of Contaminants  generated,  stored, used, disposed of, treated,
     handled,  or  shipped by Seller or any of its  Affiliates  on or before the
     Closing Date;

          (3) any Contaminants requiring Remedial Action to the extent released:
     (x) on or beneath the Real Property  prior to or on the Closing Date or (y)
     at any other location if such  substances were  generated,  used,  treated,
     transported, or Released by or on behalf of Seller or any of its Affiliates
     prior to or on the Closing Date; and

          (4) installation of pollution  control equipment or other equipment to
     bring any Real  Improvements  into compliance with any Environmental Law if
     such  equipment  is  installed  as a result  of the  failure  of such  Real
     Improvements  to be in  compliance  with  any  Environmental  Law as of the
     Closing Date.

               (b) Notwithstanding any other provision of this Agreement, Seller
          shall be  obligated  to  indemnify  and hold  harmless any Buyer Group
          Member for Loss or Expense  pursuant  to Section  10.5(a)  only if the
          aggregate  amount  of such  Loss and  Expense  exceeds  $200,000  (the
          "Environmental Threshold"),  and then only for the amount of such Loss
          and Expense that exceeds the Environmental Threshold.

               (c) Seller shall not be obligated to pay more than  $6,000,000 in
          the aggregate in respect of Loss and Expense based upon,  attributable
          to,  or  resulting  from a claim  for  indemnification  under  Section
          10.5(a).

               (d) The  indemnification  provided for in this Section 10.5 shall
          terminate  five years after the Closing  Date (and no claims  shall be
          made by any Buyer Group Member  under this  Section 10.5  thereafter),
          except that the  indemnification  by Seller  shall  continue as to any
          Loss or Expense of which any Buyer Group Member has notified Seller in
          accordance  with the  requirements  of Section 10.3 on or prior to the
          date such indemnification would otherwise terminate in accordance with
          this Section 10.5, as to which the obligation of Seller shall continue
          until the  liability of Seller shall have been  determined  and Seller
          shall have  reimbursed  all Buyer Group Members for the full amount of
          such Loss and Expense.

               (e) Buyer shall not voluntarily undertake any Cleanup at any Real
          Property unless doing so is (x) required by Environmental  Laws or (y)
          prudent and reasonable to mitigate Loss or Expense  otherwise  covered
          by  Section  10.5(a).  Any  Cleanup  at any  Real  Property  shall  be
          undertaken,  to the best of Buyer's  abilities,  in a  reasonable  and
          cost-effective  manner,  consistent  with  the use of  such  property.
          Except for Cleanup undertaken on an emergency basis to protect against
          an  imminent  risk to human  health or the  environment,  prior to the
          commencement  of any  Cleanup  for  which  Seller  may have  indemnity
          obligations  subject  to  indemnification   hereunder,   at  any  Real
          Property,  a representative  of Buyer shall provide Seller with a plan
          as to Buyer's  intended  course of action,  the projected  costs to be
          incurred in connection  therewith,  and the anticipated time frame for
          completion.  Seller  shall  have the  right to  review  such plan with
          Buyer,  to consult with Buyer  regarding  the proposed plan of action,
          and to provide comments and suggestions, which reasonable comments and
          suggestions Buyer will make good faith efforts to incorporate into the
          work plan.  Seller shall receive  periodically  written status reports
          with regard to the Cleanup efforts subject to the indemnification.

     10.6  Indemnification  Exclusive Remedy for Breach of  Representations  and
Warranties.  Should the Closing  occur,  the sole and  exclusive  remedy of each
party  against  the other  with  respect  to any and all  claims  arising  under
Sections  10.1(a)(2),  10.2(a)(2),  and  10.5(a)(1)  shall  be  pursuant  to the
indemnification provisions set forth in this Article 10.

This  Agreement  shall be  governed  by and  construed  in  accordance  with the
