Form of USG Corporation 2019 Long-Term Cash Incentive Award Agreement

Grant of Cash Incentive Award. Subject to the terms of the Plan, the Awardee has been granted a target Cash Incentive Award in an amount separately communicated in the 2019 Long-Term Incentive Plan Employee Statement sent to the Awardee (the “Target Cash Incentive Award”), payment of which depends on the Company’s performance as set forth in this Agreement and in the Statement of Performance Goals approved by the Committee (the “Statement of Performance Goals”) and, subject to Sections 3 and 4, the Awardee’s continuous employment through the last day of Performance Period #3 (as defined herein).

Earning of Award.

Performance Measure. The Awardee’s right to receive all, any portion of, or more than, the Target Cash Incentive Award will be contingent upon the achievement of specified levels of performance of the Company’s Consolidated EBITDA, as set forth in the Statement of Performance Goals and will be measured with respect to three performance periods (each, a “Performance Period”) as set forth in the table below, and 33.33% of the Target Cash Incentive Award may be earned with respect to each Performance Period in accordance with the terms below:

Below Threshold. If, upon the conclusion of each Performance Period, the Company’s Consolidated EBITDA for such Performance Period falls below the threshold level, as set forth in the Performance Matrix contained in the Statement of Performance Goals, no portion of the Cash Incentive Award allocated to such Performance Period shall become earned and such portion shall be immediately forfeited.

Threshold. If, upon the conclusion of each Performance Period, the Company’s Consolidated EBITDA for the Performance Period equals the threshold level, as set forth in the Performance Matrix contained in the Statement of Performance Goals, 50% of the Target Cash Incentive Award allocated to such Performance Period shall become earned and the unearned portion allocated to such Performance Period shall be immediately forfeited.

Between Threshold and Target. If, upon the conclusion of each Performance Period, the Company’s Consolidated EBITDA exceeds the threshold level, but is less than the target level, as set forth in the Performance Matrix contained in the Statement of Performance Goals, the percentage of the Target Cash Incentive Award allocated to such Performance Period that shall become earned will be determined by mathematical straight-line interpolation between 50% of the Target Cash Incentive Award allocated to such Performance Period and 100% of the Target Cash Incentive Award allocated to such Performance Period and the unearned portion of the Target Cash Incentive Award allocated to such Performance Period shall be immediately forfeited.

Target. If, upon the conclusion of each Performance Period, the Company’s Consolidated EBITDA for such Performance Period equals the target level, as set forth in the Performance Matrix contained in the Statement of Performance Goals, 100% of the Target Cash Incentive Award allocated to such Performance Period shall become earned.

Between Target and Maximum. If, upon the conclusion of each Performance Period, the Company’s Consolidated EBITDA exceeds the target level, but is less than the maximum level, as set forth in the Performance Matrix contained in the Statement of Performance Goals, the percentage of the Target Cash Incentive Award allocated to such Performance Period that shall become earned will be determined by mathematical straight-line interpolation between 100% of the Target Cash Incentive Award allocated to such Performance Period and 150% of the Target Cash Incentive Award allocated to such Performance Period.

Equals or Exceeds Maximum. If, upon the conclusion of each Performance Period, the Company’s Consolidated EBITDA for the Performance Period equals or exceeds the maximum level, as set forth in the Performance Matrix contained in the Statement of Performance Goals, 150% of the Target Cash Incentive Award allocated to such Performance Period shall become earned.

Conditions; Determination of Earned Award. Except as otherwise provided herein, the Awardee’s right to receive the earned portions of the Cash Incentive Award is contingent upon his or her remaining in the continuous employ of the Company, an Affiliate or a Subsidiary through the last day of Performance Period #3. Following each Performance Period, the Committee shall determine, whether and to what extent the goals relating to the Company’s Consolidated EBITDA have been satisfied for such Performance Period and shall determine the percentage of the Target Cash Incentive Award allocated to such Performance Period that shall have become earned hereunder.

Effect of Change in Control. Notwithstanding anything to the contrary in this Agreement, the following provisions shall apply in connection with a Change in Control, which, for the avoidance of doubt, shall include (I) the merger between World Cup Acquisition Corporation, an indirect, wholly-owned subsidiary of Garb. Knauf KG (“Knauf”), and the Company (the “Merger”), (II) any other Change in Control, and (III) following the consummation of the Merger, any transaction that constitutes a change in control of Knauf for purposes of Section 409A of the Code. Notwithstanding the preceding sentence, Section 4 shall apply and the following provisions of this Section shall not apply if the Change in Control occurs after termination of the Awardee’s employment due to death, Disability, or Retirement.

Assumption of Award. Upon the occurrence of a Change in Control, if the Award made under this Agreement remains outstanding at the time of such Change in Control, it shall be Assumed by the entity effecting the Change in Control, and the percentage of the Target Cash Incentive Award that may become payable to the Awardee for the Performance Period in which the Change in Control occurs and any subsequent remaining Performance Period (each, a “CIC Cash Incentive Award”) shall continue to be determined pursuant to Section 2 above, as long as the Awardee remains continuously employed through the last day of Performance Period #3; provided, however, that (i) if the Awardee’s employment is terminated due to the Awardee’s death, Disability, or Retirement (as such terms are defined in Exhibit A), the level at which each CIC Cash Incentive Award shall become earned shall be determined pursuant to Section 4, (ii) if the Awardee’s employment is terminated by the Company or a Subsidiary without Cause (as such term is defined in Exhibit A) within 12 months following the consummation of the Merger, the level at which each CIC Cash Incentive Award shall become earned shall be determined pursuant to Section 3(b), or (iii) if the Awardee’s employment is terminated by the Company or a Subsidiary without Cause within 12 months following the consummation of a Change in Control other than the Merger, the level at which each CIC Cash Incentive Award shall become earned shall be determined pursuant to Section 3(c).

Termination without Cause in Connection with the Merger.

Termination without Cause following a Change in Control other than the Merger. If the Awardee’s employment with the Company or a Subsidiary terminates without Cause within 12 months following the consummation a Change in Control other than the Merger (the “CIC Date”), subject to Section 9, the Company shall pay the Awardee an amount equal to (i) any earned portion of the Cash Incentive Award allocated to any previously completed Performance Periods that ended prior to the CIC Date, which shall be determined based on the level of achievement of the Company’s Consolidated EBITDA for such Performance Periods, which payment shall be made not later than two weeks following the date of such termination (or as soon as reasonably practicable after the Company determines the level at which the applicable performance goals were satisfied, but in no event later than the calendar year following the calendar year in which such termination occurs), and any unearned portion of the Cash Incentive Award allocated to such completed Performance Periods will be immediately forfeited, and (ii) a pro rata percentage of the Target Cash Incentive Award for the Performance Period in which the Change in Control occurs based on the number of full months during which the Awardee was employed by the Company or a Subsidiary during the Performance Period in which the CIC Date occurs, which payment shall be made as soon as practicable after the last day of the Performance Period in which the CIC Date occurs, but subject to Section 9 below, in no event shall such payment occur later than December 31^st of the calendar year following the calendar year in which the CIC Date occurs, and any remaining portion of the Cash Incentive Award allocated to the Performance Period in which the CIC Date occurs and any subsequent remaining Performance Periods will be immediately forfeited.  

Forfeiture. In addition to the forfeiture of any portion of the Cash Incentive Award pursuant to other provisions of this Agreement, if either (a) the Awardee’s employment with the Company or an Affiliate or Subsidiary terminates before the last day of Performance Period #3 for any reason other than as set forth in Sections 3 and 4 hereof, or (b) if the Committee finds that the Awardee has engaged in any fraud or intentional misconduct as described in Section 19 hereof, the entire Cash Incentive Award will be forfeited. Any portion of the Cash Incentive Award shall be considered to have been forfeited upon the event that causes such forfeiture and shall not be considered to be outstanding thereafter.

Form and Time of Payment of Cash Incentive Award. Notwithstanding anything to the contrary in this Agreement, payment of the portion of the Cash Incentive Award that becomes earned as set forth herein will be made in cash, less any applicable tax withholding. Except as otherwise provided in Sections 3 and 4, payment will be made as soon as practicable after the end of Performance Period #3 and the determination by the Committee of the level of attainment of the Company’s Consolidated EBITDA, but in no event later than December 31^st, 2022. Upon and after payment of the Cash Incentive Award pursuant to this Section 6, the Cash Incentive Award shall not be considered to be outstanding. Notwithstanding the foregoing, if the event that causes the Cash Incentive Award to be earned is a Change in Control that does not constitute a change of control for purposes of Section 409A of the Code, then to the extent necessary to comply with

Cash Incentive Award Nontransferable. Until payment is made to the Awardee as provided herein, neither the Cash Incentive Award granted hereby nor any interest therein shall be transferable other than by will or the laws of descent and distribution prior to payment.

Adjustments. The Cash Incentive Award evidenced by this Agreement is subject adjustment as provided under Section 11 of the Plan. In addition, by accepting this Cash Incentive Award, the Awardee hereby consents to any action taken by the Committee, in its sole discretion, to adjust the Company’s Consolidated EBITDA performance metric as set forth in the Statement of Performance Goals in connection with the Merger or a Change in Control and hereby acknowledges that no further consent will be sought by the Awardee for any such adjustment.

Compliance with Section 409A of the Code. To the extent applicable, it is intended that this Agreement and the Plan comply with or be exempt from the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to the Awardee. This Agreement and the Plan shall be administered in a manner consistent with this intent. Reference to Section 409A of the Code is to Section 409A of the Internal Revenue Code of 1986, as amended, and will also include any regulations or any other formal guidance promulgated with respect to such Section by the U.S. Department of the Treasury or the Internal Revenue Service. If the event triggering the right to payment under this Agreement is the Awardee’s Retirement or other separation from service with the Company and its Subsidiaries within the meaning of Section 409A(a)(2)(A)(i) of the Code and the Awardee is a “specified employee” as determined pursuant to procedures adopted by the Company in compliance with Section 409A of the Code, the date of payment under Section 3 or 4 above, as applicable, shall be the first day of the seventh month after the date of the Awardee’s separation from service or, if earlier, the date of the Awardee’s death, in each case, to the extent required to avoid the excise tax pursuant to Section 409A of the Code.

No Right to Future Grants; No Right of Employment; Extraordinary Item. In accepting the grant, the Awardee acknowledges that: (a) the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, suspended or terminated by the Company at any time, as provided in the Plan and this Agreement; (b) the grant of this Cash Incentive Award is voluntary and occasional and does not create any contractual or other right to receive future grants of Cash Incentive Awards or benefits in lieu of a Cash Incentive Award, even if Cash Incentive Awards have been granted repeatedly in the past; (c) all decisions with respect to future grants, if any, will be at the sole discretion of the Company; (d) the Awardee’s participation in the Plan is voluntary; (e) this Cash Incentive Award is an extraordinary item that does not constitute compensation of any kind for services of any kind rendered to the Company, its Affiliates and/or Subsidiaries, and which is outside the scope of the Awardee’s employment contract, if any; (f) this Cash Incentive Award is not part of normal or expected compensation or salary for any purposes, including, but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments; (g) in the event that the Awardee is an employee of an Affiliate or Subsidiary of the Company, the grant will not be interpreted to form an employment contract or relationship with the Company; and furthermore, the grant will not be interpreted to form an employment contract with the Affiliate or Subsidiary that is the Awardee’s employer; (h) no claim or entitlement to compensation or damages arises from forfeiture or termination of the Cash Incentive Award or

Continuous Employment. For purposes of this Agreement, the continuous employment of the Awardee with the Company or a Subsidiary shall not be deemed to have been interrupted, and the Awardee shall not be deemed to have ceased to be an employee of the Company or Subsidiary, by reason of (a) the transfer of the Awardee’s employment among the Company and its Affiliates and Subsidiaries or (b) an approved leave of absence.
