        <footnote id="F1">On May 22, 2015, the Reporting Person was awarded 9,000 performance-based restricted stock units (&quot;RSUs&quot;), including 4,500 RSUs subject to vesting based on the Issuer's achievement of adjusted EBITDA performance objectives and 4,500 RSUs subject to vesting based on the issuer's achievement of ROE performance objectives. The issuer achieved performance at between target and stretch levels against the adjusted EBITDA performance objective and the ROE performance objectives, resulting in the Reporting Person being entitled to receive the number of shares of the Company's common stock equal to 168.4% and 173.0% of the adjusted EBITDA and ROE RSUs awarded to the Reporting Person, respectively. Accordingly, 15,363 shares of the Company's common stock were issued to the Reporting Person as of the determination date, October 24, 2017.</footnote>
        <footnote id="F2">Pursuant to the terms of the Restricted Stock Unit Award Agreement dated May 22, 2015, common shares otherwise issuable to the Reporting Person upon vesting of the award were surrendered to the Company to settle the statutory withholding tax obligation incurred upon vesting of the award.</footnote>
        <footnote id="F3">Each RSU represents a contingent right to receive one share of GBX common stock.</footnote>
        <footnote id="F4">Pursuant to the terms of the Restricted Stock Unit Award Agreement dated May 22, 2015, 9,000 RSUs vested on October 24, 2017.</footnote>
