        <footnote id="F1">Shares received in exchange for shares of Allegiance Bancshares, Inc. (&quot;Allegiance&quot;). On October 1, 2022, pursuant to an Agreement and Plan of Merger (the &quot;Merger Agreement&quot;), Allegiance merged with and into Stellar Bancorp, Inc., formerly CBTX, Inc. (&quot;Stellar&quot;), with Stellar as the surviving entity (the &quot;Merger&quot;). Pursuant to the Merger Agreement, each issued and outstanding share of Allegiance common stock was converted into the right to receive 1.4184 shares of Stellar common stock (&quot;Exchange Ratio&quot;).</footnote>
        <footnote id="F2">Represents shares withheld to satisfy tax liability for vesting of restricted shares of common stock in connection with the closing of the Merger.</footnote>
        <footnote id="F3">Currently exercisable.</footnote>
        <footnote id="F4">Pursuant to the Merger Agreement, at the effective time of the Merger, each outstanding option to purchase Allegiance common stock fully vested and was automatically converted into an option to purchase a number of shares of Stellar common stock equal to the number of shares of Allegiance common stock subject to such option multiplied by the Exchange Ratio, and having a per share exercise price equal to the per share exercise price for shares of Allegiance common stock subject to such option divided by the Exchange Ratio.</footnote>
