                       ANNUAL MANAGEMENT INCENTIVE PROGRAM


                                 USG CORPORATION



                                     PURPOSE


     To enhance  USG  Corporation's  ability to  attract,  motivate,  reward and
retain key employees of the  Corporation and its operating  subsidiaries  and to
strengthen the existing mutuality of interest between such key employees and the
Corporation's  stockholders by offering such key employees,  who discharge their
accountabilities  in a  manner  which  makes a  measurable  contribution  to the
Corporation's earnings, incentive award opportunities.



                                  INTRODUCTION


This  Annual  Management  Incentive  Program is in effect  from  January 1, 1996
through December 31, 1996.



                                   ELIGIBILITY


Individuals  eligible for  participation  in this Program are those officers and
other key employees occupying  management positions having 775 or more points as
determined  by the  Corporation's  position  evaluation  system.  Employees  who
participate in any other annual  incentive  program of the Corporation or any of
its subsidiaries are not eligible to participate in this Program.



                                      GOALS

For the 1996 Annual Management  Incentive  Program,  goal income targets for USG
Corporation,   Subsidiaries  and  Profit  Centers  will  be  determined  by  the
Compensation  and  Organization  Committee  after  considering   recommendations
submitted  from USG  Corporation,  Operating  Subsidiaries  and  Profit  Centers
respectively.   Additionally,   Working  Capital   Management  Targets  will  be
established.  Profit Center goals will be established  which are consistent with
Corporate  and  Operating  Subsidiary  goals.  Except  in the  case  of a  Named
Executive Officer (as defined in the Administrative  Guidelines  below),  Profit
Center  goals may be adjusted by the  Chairman  of USG  Corporation  if business
conditions or other significant  unforeseen  circumstances beyond the control of
the Profit Center have a major impact on opportunity.


                                  AWARD VALUES

For the 1996 Annual Management Incentive Program,  position par values are based
on level of accountability and are expressed as a percent of approved annualized
position reference point (midpoint).  Resulting award opportunities  represent a
fully  competitive  incentive  opportunity  for  100%  (target)  achievement  of
Corporate, Operating Subsidiary and/or Profit Center goals:

                                     AWARDS


Incentive  awards for all participants in the 1996 Annual  Management  Incentive
Program  will be reviewed  and  approved by the  Compensation  and  Organization
Committee of the USG Corporation Board of Directors.

For all  participants,  the annual incentive award opportunity is the annualized
position  reference point  (midpoint) in effect at the beginning of the calendar
year multiplied by the applicable position par value percent.

Incentive awards for 1996 will be based on

     o GOAL INCOME: (net sales less cost of sales and selling and administrative
expenses) based on the Corporation's year-end financial statements.

     o WORKING  CAPITAL  MANAGEMENT:  average  monthly Net Working  Capital (net
accounts  receivable plus FIFO inventory minus accounts payable) as a percent of
annual net sales.

     o  Personal  Performance  (except  in the case of the nine (9) most  senior
executives whose awards are based solely on achievement of financial results).

     o  Except  in the  case of a Named  Executive  Officer,  other  appropriate
performance measures as approved by the Compensation and Organization  Committee
of the Board of Directors.

1.   For  participants to qualify for the USG  Corporation  segment of an award,
     USG Corporation must achieve 75% or higher of the Corporation's goal income
     target. For Group, Subsidiary and Profit Center participants to qualify for
     the  Group/Subsidiary/  Profit Center segment of an incentive  opportunity,
     the  respective  Group,  Subsidiary  or Profit  Center must  achieve 75% or
     higher  of its  goal  income  target.  The  Compensation  and  Organization
     Committee may eliminate  awards to any  participant  who fails to receive a
     personal performance rating of "Achieved Expectations" (85) or better under
     the Corporation's Performance Planning and Review system (PPR).

2.   Once the threshold  qualifiers for an incentive award are satisfied,  basic
     incentive  award  amounts  will  be  determined  by  Corporate  performance
     achievement  which meets or exceeds 75% of the Corporate  goal income or by
     Group, Subsidiary or Profit Center achievements which meet or exceed 75% of
     their respective goal income targets, according to the following schedule:


         Goal                      Goal Income Adjustment Factor
         Income                    For Corporate, Group, Subsidiary
         Achievement               or Profit Center Performance

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

3.       Basic  incentive  award  amounts  are  adjusted  to the extent that the
         percent of net working capital to net sales is reduced from or exceeded
         by the 1995 actual level.  Achievement  of working  capital  management
         targets will be measured for USG  Corporation,  North  American  Gypsum
         Group and Worldwide  Ceilings Group.  Each 0.1 reduction or increase in
         the percentage will  respectively  increase or decrease basic incentive
         awards by 2% of par according to the following schedule:

                  Average Working Capital Percent of Net Sales


Reduction in                    Increase in
Percentage        Award         Percentage         Award

4.       Except with respect to the nine (9) most senior  executives,  including
         the  Named  Executive  Officers,  whose  awards  are  based  solely  on
         achievement  of Goal Income and  Working  Capital  Management  Targets,
         incentive awards based upon achievement of Goal Income and adjusted for
         achievement  of  Working  Capital  Management  Targets  will be further
         adjusted  based upon the eligible  participants'  individual  Incentive
         Performance   Rating  derived  from  the  accomplishment  of  incentive
         performance targets according to the following schedule:


Individual               Personal Performance

- --------------------     ----------------------------


         The maximum incentive award under this Program is 200% of par.


5.       Basic  incentive  award  opportunities  and  calculations of awards for
         participants  will be based on the  achievement of specific  Corporate,
         Group, Subsidiary and/or Profit Center goal income targets as displayed
         below or, except with respect to Named Executive Officers, as otherwise
         may be established subject to approval of the Chairman:

6.       SPECIAL AWARDS

         In addition to the incentive  opportunity  provided by this Program,  a
         special   award   may   be   recommended   for   any   participant   or
         non-participant,  other than a Named Executive Officer, who has made an
         extraordinary contribution to the Corporation's welfare or earnings.

7.       STRATEGIC TARGETS

         In select  cases,  not  including  Named  Executive  Officers and other
         Corporate  Officers and Subsidiary CEOs, where the participant can make
         an individual, measurable and quantifiable contribution which will have
         significant  impact  on the  Corporation's  financial  performance  and
         profitability,  up to 25% of the  position  par or  opportunity  may be
         allocated to personal performance. Such allocations require approval of
         the Chairman of USG Corporation at the beginning of the Program year.

         For Corporate,  Group, Subsidiary and Profit Center participants with a
         25%    strategic    award     allocation,     the    Incentive    Award
         Opportunity/Calculation  will be  determined  at the  beginning  of the
         Program year.

         The  strategic  award  opportunity  which  is  available  for  personal
         performance  will be adjusted  to the extent  that  actual  performance
         exceeds or fails to meet the targeted goal.

5.       No award  will be paid to a  Program  participant  who is not a regular
         full-time  employee in good standing at the end of the calendar year to
         which the award  applies;  except an award  which  would  otherwise  be
         payable based on goal  achievement  may be  recommended in the event of
         retirement,  disability  or death or in the  event the  participant  is
         discharged  without cause from the employment of the company during the
         year.

6.       The  awards  made  to  employees   shall  become  a  liability  of  the
         Corporation or the  appropriate  subsidiary as of December 31, 1996 and
         all payments to be made  hereunder  will be made as soon as practicable

ADMINISTRATIVE GUIDELINES
- --------------------------------------------------------------------------------


1.        Award values will be based on position reference points (midpoints) in
          effect for each qualifying  position at the beginning of the year. Any
          change in duties, dimensions or responsibilities of a current position
          resulting in a new evaluation and an increase or decrease in reference
          points will be applied  for  Incentive  Program  purposes on a prorata
          basis with the respective  reference  point and par value to apply for
          the actual number of full months of service at each evaluation  except
          for such a change with respect to a Named Executive Officer,  in which
          case any change in  reference  points and par value,  for any  reason,
          shall not become effective until January 1 of the following year.

2.       As provided by the Program,  no award is to be paid any participant who
         is not a regular full-time  employee 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 or dies, or is
         discharged  from the  employment  of the  Company  without  cause,  the
         participant (or beneficiary) may receive 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
          parent Corporation or a Subsidiary who are transferred during the year
          to a  position  covered  by the Annual  Management  Incentive  Program
          (other than a Named  Executive  Officer) 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 par values to
          apply.  For  example,   a  Marketing  Manager  promoted  to  Director,
          Marketing on August 1, will be eligible to receive a prorata award for
          seven  months  based on the  Marketing  Manager  Plan  provisions  and
          values,  and for  five  months  under  the  Annual  Incentive  Program
          provisions and par values.

4.       In the event of transfer of an employee  (other than a Named  Executive
         Officer) from an assignment which does not qualify for participation in
         any  incentive  or bonus plan to a position  covered by the 1996 Annual
         Management  Incentive Program,  the employee is eligible to participate
         in the Annual  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.

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 service is required for award consideration.

6.       Exceptions to established administrative guidelines can only be made by
         the Compensation  and  Organization  Committee and only with respect to
         participants other than Named Executive Officers.

7.       For purposes of this Program,  a "NAMED EXECUTIVE OFFICER" will include
         any  executive  officer who is deemed a "named  executive  officer" for
         1996  under  Item 402  (a)(3) of  Regulation  S-K under the  Securities
         Exchange  Act  of  1934  and  was  employed  by  the  Corporation  or a
         Subsidiary on the last day of the year.
