      The Maximum  Award  Opportunity  is a percentage of the Base Salary of the

                 II                            80%
                III                            60%
                 IV                            40%
                 V                             25%
                 VI                            15%
       ------------------------------------------------------------

5.    AMOUNT/PAYMENT OF AWARD

      A  Participant's  Maximum  Award  under  this Plan shall be the sum of two
      parts:  (i) an  Individual  Performance  Portion  calculated  pursuant  to
      Section  5(A);  and (ii) a  Quantitative  Performance  Portion  calculated
      pursuant to Section 5(B).

      A Participant's level of participation in the Plan will determine how much
      of  his/her  Maximum  Award   Opportunity  will  be  based  on  individual
      performance  criteria  pursuant to Section 5(A) and how much will be based
      on quantitative  criteria  pursuant to Section 5(B). The chart below shows
      the weighting of each performance measure by Plan Level.
      These percentages are as follows:

      A.   Individual Performance Portion

           At the beginning of each Plan Year,  the Chief  Executive  Officer or
           the   Participant's   immediate   supervisor   will  meet  with  each
           Participant to establish  Performance  Goals for each Participant for
           the year.  These  goals  should be  signed by the  Participant  as an
           acknowledgment  of what is expected and approved by the Participant's
           immediate supervisor.

           The  performance  of the  Participant  for  each  Plan  Year  will be
           evaluated  with respect to achievement  of the  Performance  Goals. A
           Performance   Rating   Percentage  for  each   Participant   will  be
           determined. The Individual Performance Portion, if any, earned by the
           Participant  will be based on this final rating.  The evaluation of a
           Participant's   performance  in  achieving   his/her  goals  will  be
           subjective and the Individual  Performance  Portion deemed earned, as
           determined  by the CEO of the Company and approved by the  Committee,
           shall be conclusive.

           The  percentage of the  Individual  Performance  Portion of the Award
           earned will be based on the following chart:

            ---------------------------------------------------------
                Performance Rating            Percentage of
                    Percentage         Individual Performance
                                           Portion Earned

                       70-74                     30%
                       75-79                     44%
                       80-84                     58%

                       90-94                     86%
                   95 and above                 100%
            ---------------------------------------------------------

           A minimum  Performance  Rating Percentage of 70% will be required for
           any Award to be earned for a Plan Year

      B.   Quantitative Performance Portion

           The Quantitative  Performance  Portion of an Award will be determined
           upon  the  achievement  of  various   measurable   corporate   and/or
           operational  goals.  These goals will be established by the Committee
           prior to the  beginning of each Plan Year.  Awards will be based upon
           the  achievement  of different  goals and  performance  measurements,
           depending  on whether the  Participant  is a  Corporate  Participant,
           Group Participant,  Division Participant or Mine/Facility Participant
           and the specific position held.



           The  following  chart  shows  the  weighting  each  goal  has  in the
           determination   of   each   Participant's    potential   Quantitative
           Performance Portion:

                     i. The goals  established  under  Sections 5(A) and (B) for
                Group  Participants  who  possess  responsibility  for  multiple
                operations will equal the weighted average composite goal of the
                Divisions,   Mines   and/or   Facilities   for  which  they  are
                responsible. The goals for Division Participants shall equal the

                     ii. The Committee  shall approve any and all payments under
                this Plan and  reserves  the  discretionary  right to  increase,

                be payable under the Plan.

                    iii. Awards determined under this Plan may only be paid if:

                   -- They are approved by the Committee; and

                  -- The Participant continues to be employed by the Company and
                 continues to perform in a  satisfactory  manner through the day
                 the approved Awards are actually paid.


                     iv. Any rights a  Participant  may have to receive an Award
                will be forfeited if the Participant's  full-time  employment is
                terminated  prior to the actual  date of payment;  however,  the
                Committee shall determine to what extent, if any, an Award shall
                be  payable  under  the  Plan  and may  elect to make a pro rata
                payment (based on full months of  participation  during the year
                or otherwise) in its sole discretion.

6.    PAYMENT OF AWARD

      The Award,  if any,  earned in accordance  with Section 5 shall be paid in
      cash by the Company to the Participant within a reasonable  period,  which
      in most cases  will  usually be thirty  (30) days  after  approval  of the
      Awards by the Committee.

7.    DEATH OR DISABILITY

      In the event of a  Participant's  death or permanent and total  disability
      prior to  receiving  his or her  Award,  a pro rata  payment of such Award
      (based on full months of  participation)  shall be paid to the Participant
      or to the Participant's designated beneficiary (or to his or her estate in
      the event the  Participant  dies without  previously  having  designated a
      beneficiary in writing to the Company) pursuant to Section 6.

8.   AMENDMENT OR TERMINATION OF THE PLAN

      The Committee  reserves the right to terminate or amend the Plan, in whole
      or in part, at any time and from time to time,  provided that no amendment
      or termination  shall adversely  affect any Award  previously  earned by a
      Participant.

9.      EFFECTIVE DATE OF THE PLAN

     The Plan shall become  effective and Awards  hereunder may be earned on and
     after  January 1, 1998 and until such time as the Plan shall be  terminated
     by the Committee.

10.     LIMITATION ON AWARDS

     The maximum  aggregate  Awards  payable under the Plan during any Plan Year
     shall  not  exceed  7.5% of the  Company's  reported  net  income  for that
     calendar year.
