2019 Annual Management Incentive Program of USG Corporation (Elected Officers Only)

If the Board, or an appropriate committee thereof, has determined that any fraud or intentional misconduct by an elected 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 elected officer after January 1, 2019, 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 elected 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 elected 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 elected officer’s rights to any incentive compensation that would otherwise be awarded under this Program shall be forfeited.

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.

The Committee shall review and approve the awards recommended for eligible participants in this Program. The Committee shall submit to the Board, for its ratification, a report of the awards for all eligible participants approved by the Committee in accordance with the provisions of the Program.

Consistent with the terms of the Plan, 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 (including of the Management Objective(s)) and applicable awards in writing as provided in the Plan.

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.

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 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.

The following administrative guidelines will be applied and administered by the Committee consistent with the requirements for “performance-based compensation” in Section 162(m) of the Internal Revenue Code and the applicable regulations thereunder to the extent applicable.

Award values will be based on annualized salary in effect on March 1, 2019 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.

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 Executive Vice President and Chief Administrative Officer, 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 Corporation without cause, or is on an approved unpaid leave, the participant (or beneficiary) may, in the Committee’s sole discretion, 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.

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.

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.

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.

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