                                     AWARDS

     Incentive awards for all participants in the 2002 Annual Management
     Incentive Program will be reviewed and approved by the Committee. For all
     participants, the annual incentive award par opportunity is the annualized
     salary in effect at the beginning of the calendar year (March 1, 2002 of
     the calendar year for the sixteen most senior executives) multiplied by the
     applicable position target incentive value percent. The individual maximum
     total incentive award for all segments of this Program is 200% of the par
     incentive opportunity.

     Incentive awards for 2002 will be based on a combination of the following
     elements:

I.   CONSOLIDATED EBITDAR:                                      40% OF INCENTIVE

     Consolidated EBITDAR will be based on the Corporation's year-end financial
     statements. For the top senior executives this portion of the award is
     based on Consolidated EBITDAR and represents 60% of the incentive par
     (except for the Vice President International & Technology, USG Corporation,
     the President and Chief Operating Officer, L&W Supply, the President CGC
     and the President USG Mexico who will be based 30% on Consolidated EBITDAR
     and 30% on business unit Operating Profit).


                                      (OR)
     OPERATING PROFIT:

     Profit Center specific goals (net sales less cost of sales and selling and
     administrative expenses) based on the Corporation's year-end financial
     statements at half of the total weighting on financial goals, with the
     other half on Consolidated EBITDAR. The top senior executives, except for
     those listed above, will not have business unit Operating Profit goals.

     Consolidated EBITDAR and business unit Operating Profit segment award
     amounts will be adjusted by a factor of up to two times the amount that
     actual results differ from goals according to the following schedule:



          Consolidated EBITDAR/               Adjustment Factor for Consolidated
         Business Unit Achievement                      or Business Unit
         -------------------------                      ----------------

                    80%                                        60%

                   110%                                       120%
                   120%                                       140%
                   140%                                       180%
                   150%                                       200%



                                       79







     Consolidated EBITDAR or business unit Operating Profit Achievement results
     and adjustment factors between the thresholds listed above are prorated.

     Other appropriate performance measures may be assigned as approved by the
     Committee.


II.  STRATEGIC FOCUS TARGETS:                                   40% OF INCENTIVE

     Strategic Focus Targets will be measurable, verifiable and derived from the
     formal strategic planning process (e.g., Customer Satisfaction, Cost
     Reduction, Overhead Reduction and Working Capital Reduction). The award
     adjustment factor for this segment will range from 1.0 (after achieving
     target performance levels) to 2.0 for maximum attainment. The participant's
     manager will assign specific Strategic Focus Target assignments and
     weightings to each participant. The weighting on an individual Strategic
     Focus Target will not be less than 10%. The weighting of all assigned
     Strategic Focus Targets will equal 40%.

III. PERSONAL PERFORMANCE:                                      20% OF INCENTIVE

     Participants (except as noted below) will have a third segment comprising
     20% of their incentive award based upon their individual Personal
     Performance Rating according to the following schedule:






         Personal                                           Personal Performance

         Partially Achieved Expectations                            0.8 -- 0.9
      ----------------------------------------------------------------------------------------
         Did Not Meet Expectations                          No Award will be paid under any
                                                            segment of this plan if the
                                                            Personal Performance rating is
                                                            "Did Not Meet Expectations"
      ----------------------------------------------------------------------------------------



- -    The top sixteen senior executives, and the Presidents of CGC and USG Mexico
     do not have Personal Performance as an element of their award. Awards for
     these participants are weighted 60% on financial targets (Consolidated
     EBITDAR or a combination of Consolidated EBITDAR and business unit
     Operating Profit) and 40% on Strategic Focus Targets.



                                       80




- -    To qualify for an award for Personal Performance, an award must be earned
     from Consolidated EBITDAR, the participant's business unit Operating
     Profit, or the participant's Strategic Focus Targets.

- -    A Personal Performance Rating of DNM (Did Not Meet Expectations)
     disqualifies the participant from any portion of an award under the
     Program.

6.       The awards made to employees shall become a liability of the

         after said awards have been approved by the Committee.


                            ADMINISTRATIVE GUIDELINES


1.       Award values will be based on annualized salary in effect for each
         qualifying participant at the beginning of the year (March 1, 2002 for
         the sixteen most senior executives). Any change in duties, dimensions
         or responsibilities of a current position resulting in an increase or
         decrease in salary range reference point or market rate will result in
         pro-rata incentive award. Respective reference points, target incentive
         values or goals will be applied based on the actual number of full
         months of service at each position.

2.       As provided by the Program, no award is to be paid any participant who
         is not a regular full-time employee, (or a part time employee as
         approved by the Vice President Human Resource, USG Corporation) in good
         standing at the end of the calendar year to which the award applies.
         However, in the event an eligible participant with three (3) or more
         months of active service in the Program year subsequently retires,
         becomes disabled, dies, is discharged from the employment of the
         Company without cause, or is on an approved unpaid leave, the
         participant (or beneficiary) may be recommended for an award which
         would otherwise be payable based on goal achievement, prorated for the
         actual months of active service during the year.

3.       Employees participating in any other incentive or bonus program of the
         Corporation or a Subsidiary who are transferred during the year to a
         position covered by the Annual Management Incentive Program will be
         eligible to receive a potential award prorated for actual full months
         of service in the two positions with the respective incentive program
         and target incentive values to apply. For example, a Marketing Manager
         promoted to Director, Marketing on August 1, will be eligible to
         receive a pro-rata award for seven months based on the Marketing
         Manager Plan provisions and values, and for five months under the
         Annual Management Incentive Program provisions and target incentive
         values.

4.       In the event of transfer of an employee from an assignment which does
         not qualify for participation in any incentive or bonus plan to a
         position covered by the Annual Management Incentive Program, the
         employee is eligible to participate in the Annual Management Incentive
         Program with any potential award prorated for the actual months of
         service in the position covered by the Program during the year. A
         minimum of three months of service in the eligible position is
         required.



                                       83







5.       Participation during the current Program year for individuals employed
         from outside the Corporation is possible with any award to be prorated
         for actual full months of service in the eligible position. A minimum
         of three full months of eligible service is required for award
         consideration.

6.       Exceptions to established administrative guidelines can only be made by
         the Committee
