        <footnote id="F1">Represents the grant of restricted stock units (the &quot;RSU&quot;) that vest in three equal annual installments beginning on May 9, 2019, subject to continued service.  The RSU is the initial equity grant to which each non-employee director is entitled for service on the Issuer's board of directors pursuant to the non-employee director compensation policy that has been approved by the compensation committee of the Issuer's board of directors. The number of shares subject to the RSU was determined by reference to the price of the Issuer's common stock in its initial public offering, or $11 per share.</footnote>
