        <footnote id="F1">Each restricted stock unit represents a contingent right to receive one share of UTI Common Stock.</footnote>
        <footnote id="F2">This Form 4/A does not report a new transaction.  The reporting person's original Form 4 incorrectly reported these securities as Common Stock rather than restricted stock units.</footnote>
        <footnote id="F3">The restricted stock units vest in three equal annual installments beginning on March 2, 2021.</footnote>
        <footnote id="F4">The incorrect classification described in footnote (2) above resulted in incorrect reporting of beneficial ownership of the UTI Common Stock in the original Form 4.  As of the date of this Form 4/A, none of the restricted stock units has vested.  The beneficial ownership of the restricted stock units has been corrected in this Form 4/A and reflects the reporting person's correct ownership as of the date of this filing.</footnote>
