USG CORPORATION RESTRICTED STOCK UNITS AGREEMENT

Payment of RSUs. The RSUs covered by this Agreement shall become payable to the Grantee if they become nonforfeitable in accordance with Section 2, Section 3 or Section 4 hereof.

Vesting of RSUs. Subject to the terms and conditions of Sections 3, 4 and 5 hereof, the Grantee’s right to receive the Common Shares subject to the RSUs shall become nonforfeitable as and to the extent set forth in the Award Acceptance documentation on the Morgan Stanley Wealth Management website if the Grantee remains continuously employed until such time as is set forth therein as the Grantee’s Vest Date.

Effect of Change in Control. In the event of a Change in Control prior to the RSUs becoming nonforfeitable as provided in Section 2 above, and at a time when the RSUs have not been forefeited, the RSUs covered by this Agreement shall be treated in connection with such Change in Control as set forth in this Section 3. If the entity effecting the Change in Control Assumes the RSUs, Section 3(a) shall apply. If the entity effecting the Change in Control does not Assume the RSUs, Section 3(b) shall apply.

RSUs Assumed by Successor: If the RSUs that are outstanding at the time of a Change in Control are Assumed by the entity effecting the Change in Control, the RSUs shall become nonforfeitable and payable to the Grantee pursuant to Section 2 above. Subject to the following sentence, all of the RSUs that are outstanding at the time of the Grantee’s termination of employment prior to the RSUs becoming nonforfeitable and payable to the Grantee shall be forfeited. Notwithstanding the preceding sentence, any RSUs that have not become nonforfeitable and payable to the Grantee shall become nonforfeitable and

the involuntary termination of the Grantee’s employment for reasons other than Cause (as defined in Exhibit A);

the Grantee’s voluntary termination of employment for Good Reason (as defined in Exhibit A); or

the termination of the Grantee’s employment due to the Grantee’s death or Disability (as such term is defined in Exhibit A).

RSUs Not Assumed by Successor. If the RSUs that are outstanding at the time of a Change in Control are not Assumed by the entity effecting the Change in Control, such RSUs shall immediately become nonforfeitable and payable to the Grantee.

Effect of Death or Disability. Notwithstanding Section 2 above, if the Grantee’s employment with the Company or a Subsidiary terminates due to the Grantee’s death or Disability before the RSUs become nonforfeitable, at a time when the RSUs have not been forfeited and before the occurrence of a Change in Control, the RSUs covered by this Agreement shall immediately become nonforfeitable and payable to the Grantee.

Other Employment Terminations. Notwithstanding any other provision herein, in the event that either (i) the Grantee’s employment shall, at a time when the RSUs remain forfeitable, terminate in a manner other than any specified in Section 3 or 4 above or (ii) the Board (or a committee of the Board) finds that the Grantee has engaged in any fraud or intentional misconduct as described in Section 20 hereof, the Grantee shall forfeit any RSUs that have not become nonforfeitable by such Grantee upon such termination or finding, as applicable. RSUs 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 RSUs. Except as otherwise provided for in Section 9, payment for the RSUs, after and to the extent they have become nonforfeitable, shall be made in the form of Common Shares. Payment shall be made within ten (10) days following the date on which the RSUs become nonforfeitable in accordance with Section 2, Section 3 or Section 4 hereof. Upon and after payment for any RSUs pursuant to this Section 6, such RSUs shall not be considered to be outstanding. Notwithstanding the foregoing, if the event that causes the RSUs to become nonforefeitable 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 Section 409A of the Code, payment will be made on the next date or event under the Agreement that constitutes a permissible payment date or event under Code Section 409A. To the extent that the Company is required to withhold federal, state, local or foreign taxes in connection with the delivery of Common Shares to the Grantee or any other person under this Agreement, the number of Common Shares to be delivered to the Grantee or such other person shall be reduced (based on the Market Value per Share on the date Common Shares are delivered to the Grantee) to provide for the taxes required to be withheld, with any fractional shares that would otherwise be delivered being rounded up to the next nearest whole share. The Board (or a committee of the Board) may, at its discretion, adopt any alternative method of providing for taxes to be withheld.

Payment of Dividend Equivalents. From and after the Date of Grant and until the earlier of (a) the time when Common Shares are delivered to the Grantee as described in Section 6 or (b) the time when the Grantee’s right to receive Common Shares upon payment of RSUs is forfeited, on the date that the Company pays a cash dividend (if any) to holders of Common Shares generally, the Grantee shall be entitled to a number of additional whole RSUs determined by dividing (i) the product of (A) the dollar amount of the cash dividend paid per Common Share on such date and (B) the total number of RSUs (including dividend equivalents paid thereon) previously credited to the Grantee as of such date, by (ii) the Market Value per Share on such date. Such dividend equivalents (if any) shall be subject to the same terms and conditions and shall be settled or forfeited in the same manner and at the same time as the RSUs to which the dividend equivalents were credited.

RSUs Nontransferable. Neither the RSUs granted hereby nor any interest therein or in the Common Shares related thereto shall be transferable other than by will or the laws of descent and distribution prior to payment.

Adjustments. In the event of any change in the aggregate number of outstanding Common Shares by reason of (a) any stock dividend, extraordinary dividend, stock split, combination of shares, recapitalization or other change in the capital structure of the Company, or (b) any Change in Control, merger, consolidation, spin-off, split-off, spin-out, split-up, reorganization or partial or complete liquidation, or other distribution of assets, issuance of rights or warrants to purchase securities, or (c) any other corporate transaction or event having an effect similar to any of the foregoing, then the Board (or a committee of the Board) shall adjust the number of RSUs then held by the Grantee in such manner as to prevent dilution or enlargement of the rights of the Grantee that otherwise would result from such event. Moreover, in the event of any such transaction or event, the Board (or a committee of the Board), in its discretion, may provide in substitution for any or all of the Grantee’s rights under this Agreement such alternative consideration as it may determine to be equitable in the circumstances, subject to the provisions of Section 3 of this Agreement.

Compliance with Section 409A of the Code. To the extent applicable, it is intended that this Agreement and the Plan comply with 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 Grantee. 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 Grantee’s separation from service with the Company and its Subsidiaries within the meaning of Section 409A(a)(2)(A)(i) of the Code and the Grantee 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 6 above shall be the first day of the seventh month after the date of the Grantee’s separation from service or, if earlier, the date of the Grantee’s death.

No Right to Future Grants; No Right of Employment; Extraordinary Item: In accepting the grant, Grantee 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 Award Agreement; (b) the grant of the RSUs is voluntary and occasional and does not create any contractual or other right to receive future grants of RSUs, or

Grantee understands that Data may be transferred to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in Grantee’s country or elsewhere, and that the recipient’s country may have different data privacy laws and protections than Grantee’s country. Grantee understands that Grantee may request a list with the names and addresses of any potential recipients of the Data by contacting Grantee’s local human resources representative. Grantee authorizes the recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, for the purposes of implementing, administering and managing Grantee’s participation in the Plan, including any requisite transfer of such Data as may be required to a broker or other third party with whom Grantee may elect to deposit any Shares acquired. Grantee understands that Data will be held only as long as is necessary to implement, administer and manage Grantee’s participation in the Plan. Grantee understands that Grantee may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing Grantee’s local

Relation to Plan. This Agreement is subject to the terms and conditions of the Plan. In the event of any inconsistency between the provisions of this Agreement and the Plan, the Plan shall govern. All terms used herein with initial capital letters and not otherwise defined herein that are defined in the Plan shall have the meanings assigned to them in the Plan. The Board (or a committee of the Board) acting pursuant to the Plan, as constituted from time to time, shall, except as expressly provided otherwise herein, have the right to determine any questions which arise in connection with the grant of the RSUs.

Amendments. Any amendment to the Plan shall be deemed to be an amendment to this Agreement to the extent that the amendment is applicable hereto; provided, however, that no amendment shall adversely affect the rights of the Grantee under this Agreement without the Grantee’s consent.

Severability. Subject to Section 20, if any provision of this Agreement or the application of any provision hereof to any person or circumstances is held invalid, unenforceable or otherwise illegal, the remainder of this Agreement and the application of such provision to any other person or circumstances shall not be affected, and the provisions so held to be invalid, unenforceable or otherwise illegal shall be reformed to the extent (and only to the extent) necessary to make it enforceable, valid and legal.

Successors and Assigns. Without limiting Section 8 hereof, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the successors, administrators, heirs, legal representatives and assigns of the Grantee, and the successors and assigns of the Company.
