        <footnote id="F1">Each restricted stock unit (&quot;RSU&quot;) represents a conditional right to receive one share of common stock of the issuer. Dividend equivalents in the form of additional RSUs (&quot;Additional RSUs&quot;) accrue with respect to RSUs (and any Additional RSUs previously accrued) when dividends are paid on shares of common stock of the issuer.</footnote>
        <footnote id="F2">The RSUs and Additional RSUs vest in equal increments on a daily basis over one year and convert into an equivalent number of shares of common stock of the issuer on the first anniversary of the grant date. Upon vesting, all fractional shares underlying the RSUs and Additional RSUs are cancelled.</footnote>
        <footnote id="F3">As previously reported, on May 9, 2019, the reporting person was granted 1,487 RSUs pursuant to the Hexcel Corporation 2013 Incentive Stock Plan. On August 9, 2019, the reporting person received dividend equivalents in the form of 3.10 Additional RSUs, based on the $81.32 market price per underlying share on the dividend payment date.</footnote>
