Explanation of Responses:

1. These Market Share Units were granted on February 11, 2015. The Board of Directors (the "Board") certified performance of these Market Share Units on February 14, 2018 and USG Corporation (the "Company") issued to the reporting person 1.33 shares of the Company's common stock for the Market Share Units originally granted, based on the closing prices of shares of the Company's common stock on the New York Stock Exchange for the first fifteen trading days in January 2018.

2. Shares withheld to satisfy tax withholding obligation with respect to Market Share Units that became earned.

3. Each Market Share Unit represents the right to receive one share of common stock assuming certain market price targets are achieved. The Market Share Units vesting and the actual number of shares received are contingent on the Company's common stock achieving certain pre-defined market price levels during the performance period and continued employment.

4. Generally, the Market Share Units will be earned, if at all, once the Board certifies that pre-determined market price targets of the Company's common stock are attained, provided that the reporting person remains continuously employed by the Company or a subsidiary through December 31, 2020.
