        <footnote id="F1">Represents restricted stock units (&quot;RSUs&quot;) granted to the Reporting Person under the Issuer's 2018 Equity Incentive Plan. Each RSU represents the contingent right to receive one share of Common Stock. Subject to the terms of the award agreement evidencing the grant of the RSUs, one-third of the RSUs vests on each of the first three anniversaries of January 4, 2022, provided that the Reporting Person remains in continuous service with the Issuer through each
vesting date.</footnote>
        <footnote id="F2">Represents performance-based restricted stock units (&quot;PRSUs&quot;) granted to the Reporting Person under the Issuer's 2018 Equity Incentive Plan. Each PRSU represents the contingent right to receive one share of Common Stock. Subject to the terms of the award agreement evidencing the grant of the PRSUs, vesting of a percentage of the PRSUs (including up to 200%) is 60% dependent on the total shareholder return of Issuer from January 4, 2022 through January 4, 2025  relative to the total shareholder return of certain other companies over that same time period, and 40% dependent on the market share of single family completions of Issuer from January 4, 2022 through January 4, 2025, provided that the Reporting Person remains in continuous service with the Issuer through each vesting date.</footnote>
