AWARDS
 Incentive awards for all participants in this Program will be reviewed and approved by the
Committee. For all participants, the annual incentive award par opportunity is the annualized
salary approved by March 31, 2010 that is in effect on April 1, 2010 multiplied by the applicable
position target incentive value percent.Incentive awards for 2010 will be based on a combination of the following elements:
 I.
    
    CONSOLIDATED NET EARNINGS                   
        40% OF INCENTIVE
 Consolidated Net Earnings will be as reported on the Corporations year-end financial
statements with adjustments for significant non-operational charges. Such adjustments will be
defined by March 31, 2010 and have in the past been for Fresh Start Accounting, asbestos,
restructuring charges, bankruptcy expenses and the cumulative impact of new accounting
pronouncements. For all participants, this portion of the award represents 40% of the incentive
par. This portion of the award will be paid from a pool funded by Consolidated Net Earnings
results according to the following schedule:
 $0 to $75 Million Net Earnings
    
    2.41% of this tier will fund the pool$75+ to $150 Million Net Earnings
    
    2.05% of this tier will fund the pool$150+ to $400 Million Net Earnings
    
    1.73% of this tier will fund the pool$400+ to $575 Million
    
    1.45% of this tier will fund the pool
 Should consolidated net earnings be negative this pool will not be funded and payout for this
element will be zero. This is the same pool from which awards based on Consolidated Net Earnings
will be paid under the USG Corporation 2010 Annual Management Incentive Program for employees,
other than executive officers, occupying positions in Broadband 11 or higher (the Other Program).
Each tier of earnings is calculated separately and added together to determine the total pool.
This amount is then divided by the sum of the Net Earnings pars for all participants in this
Program and the Other Program. The factor derived from this method is then applied to each
participants Net Earnings pars to determine the individual award for this segment. For each
executive officer, (i) their individual Net Earnings par shall be determined by March 31, 2010, and
(ii) their individual factor shall be determined by taking into account the Net Earnings par of all
participants eligible to participate in the Program and the Other Program as of March 31, 2010 and
based on the sum of all such participants Net Earnings par as determined by March 31, 2010.
Notwithstanding the prior sentence nor any other provision in this Program, each executive
officers factor may be decreased, but not increased, due to changes in the total Program and Other
Program par after March 31, including, but not limited to, changes triggered by the addition or
removal of a participant from the Program or the Other Program or changes in any participants Net
Earnings par.
 II.
    
    FOCUS TARGETS:                
                                       40% OF INCENTIVE
 Focus Targets will be measurable, verifiable and derived from the formal strategic planning
process. For 2010, Focus Targets are expected to include Total Overhead, Customer Satisfaction,
Cost Reduction, Business Unit Gross Profit or other operational priorities. The Focus Targets will
be determined by March 31, 2010. The award adjustment factor for this segment will range from 0.5
(after achieving a minimum threshold performance level) to 2.0 for maximum attainment.
 The weighting on any individual Focus Target generally will be in 5% increments and not be less
than 10%.The weighting of all assigned Focus Targets will equal 40% of the individuals total par.

GENERAL PROVISIONS
 1.
    
    If the Board, or an appropriate committee thereof, has determined that any fraud
or intentional misconduct by an executive officer was a significant contributing factor to
the Corporation having to restate all or a portion of its financial statement(s), the Board
or committee shall take, in its discretion, such action as it deems necessary to remedy the
misconduct and prevent its recurrence. In determining what remedies to pursue, the Board or
committee will take into account all relevant factors, including whether the restatement was
the result of fraud or intentional misconduct. The Board may, to the extent permitted by
applicable law, require reimbursement of any award under this Program paid to the executive
officer after January 1, 2010, if and to the extent that a) the amount of the award was
calculated based upon the achievement of certain financial results that were subsequently
reduced due to a restatement, b) the executive officer engaged in any fraud or intentional
misconduct that caused or contributed to the need for the restatement, and c) the amount of
the compensation that would have been awarded to the executive officer under this Program
had the financial results been properly reported would have been lower than the amount
actually awarded. The remedy specified herein shall not be exclusive and shall be in
addition to every other right or remedy at law or in equity that may be available to the
Corporation. If this paragraph 1 is held invalid, unenforceable or otherwise illegal, the
remainder of this Program shall be deemed to be unenforceable due to a failure of
consideration, and the executive officers rights to any incentive compensation that would
otherwise be awarded under this Program shall be forfeited.In order to be entitled to an award of compensation under this Program, an executive officer
must execute a written acknowledgement that such award shall be subject to the terms and
conditions of this paragraph 1.2.
    
    The Committee reserves the right to adjust award amounts under this Program down based on its
assessment of the Corporations overall performance relative to market conditions, provided,
however, in no event may the Committee adjust an award under this Program upward.3.
    
    The Committee shall review and approve the awards recommended eligible participants in this
Program. The Committee shall submit to the Board of Directors, for its ratification, a report
of the awards for all eligible participants approved by the Committee in accordance with the
provisions of the Program.4.
    
    The Committee shall have full power to make the rules and regulations with respect to the
determination of achievement of goals and the distribution of awards. No awards will be made
until the Committee has certified financial achievements and applicable awards in writing.5.
    
    The judgment of the Committee in construing this Program or any provisions thereof, or in
making any decision hereunder, shall be final and conclusive and binding upon all employees of
the Corporation and its subsidiaries whether or not selected as beneficiaries hereunder, and
their heirs, executors, personal representatives and assignees.

6.
    
    Nothing herein contained shall limit or affect in any manner or degree the normal and usual
powers of management, exercised by the officers, and the Board of Directors or committees
thereof, to change the duties or the character of employment of any employee of the
Corporation or to remove the individual from the employment of the Corporation at any time,
all of which rights and powers are expressly reserved.7.
    
    The awards made to employees shall become a liability of the Corporation or the appropriate
subsidiary as of December 31, 2010 and all payments to be made hereunder will be made as soon
as practicable, but in any event before two and one half months after December 31, 2010, after
said awards have been approved by the Committee.
 ADMINISTRATIVE GUIDELINES
 1.
    
    Award values will be based on annualized salary in effect on April 1, 2010 for each
qualifying participant. 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 a 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.
    
    No award is to be paid to any participant who is not a regular full-time employee, (or a part
time employee as approved by the Senior Vice President, Human Resources, USG Corporation) in
good standing at the end of the calendar year to which the award applies. However, if 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 this 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.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 this Program, the
employee is eligible to participate in this Program with any potential award prorated for the
actual months of service in the position covered by this 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 eligible service is required for award
consideration.6.
    
    Exceptions to established administrative guidelines can only be made by the Committee.
