Pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the &#x201c;Securities Act&#x201d;), this registration statement shall also cover any additional shares of Common Stock that become issuable under the 2023 A&amp;amp;R Incentive Plan by reason of any stock split, stock dividend, recapitalization or other similar transaction effected without the Company&#x2019;s receipt of consideration that increases the number of the outstanding shares of Common Stock.&lt;br/&gt;&lt;br/&gt;(1b) Estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(h) and Rule 457(c) promulgated under the Securities Act.
