        <footnote id="F1">On April 27, 2026, the issuer and the reporting person entered into an Amended and Restated Executive Employment Agreement (the &quot;A&amp;R Agreement&quot;), pursuant to which the issuer agreed to grant the reporting person an option to purchase 500,000 shares of common stock at an exercise price equal to the fair market value of the common stock on the grant date. The Stock Option was granted pursuant to Section 3(d) of the A&amp;R Agreement and the Z Squared, Inc. 2025 Incentive Compensation Plan. The Stock Option vests in full on the date the fair market value of the common stock increases by 50% above the grant-date fair market value, as determined by the Board in its reasonable discretion, and remains exercisable for ten (10) years from the grant date, subject to earlier termination under the 2025 Plan and applicable award agreement.</footnote>
