Article 10 and Article 15 of the Certificate contain such provisions, and provides that if the DGCL is amended to authorize the further elimination or limitation of a director&#8217;s or officer&#8217;s liability, then the liability of our directors and officers will automatically be limited to the fullest extent provided by law.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><font style="visibility:hidden;">&#8203;</font></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">In addition, Section 145 of the DGCL authorizes a court to award, or a corporation&#8217;s board of directors to grant, indemnity to directors and officers under certain circumstances for liabilities incurred in connection with their activities in such capacities (including reimbursement for expenses incurred). Under Article 11 of the Certificate and Article 7 of the Bylaws, the Company must indemnify its directors and officers to the fullest extent permitted by the DGCL and, subject to very limited exceptions, must also advance expenses, as incurred, to its directors and officers in connection with any action, suit, or proceeding, to the fullest extent permitted by Delaware law, provided that the party seeking indemnification acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company, and had no reasonable cause to believe his or her conduct was unlawful. In addition, the Bylaws permit the Company to indemnify employees and others and advance expenses to them in connection with any action, suit, or proceeding, in the manner and to the same extent as required for directors or officers.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><font style="visibility:hidden;">&#8203;</font></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">In the case of an action or suit by or in the right of the Company to procure a judgment in its favor, Section 145(b) of the DGCL and Article 7.2 of the Bylaws provide that no indemnification shall be made in respect of any claim, issue or matter as to which such party shall have been adjudged to be liable to the Company unless and only to the extent that an appropriate court shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such party is fairly and reasonably entitled to indemnity for such expenses that the court shall deem proper.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><font style="visibility:hidden;">&#8203;</font></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">In addition, the Company has entered into individual indemnification agreements with each of its directors and certain officers to provide them with the procedural and substantive rights to indemnification currently set forth in the Certificate and Bylaws. The right to indemnification (and related advancement of expenses) provided by these agreements applies to all covered claims, whether such claims arose before or after the effective date of the contract, other than liabilities arising from actions or omissions (a) regarding enforcement of the indemnification agreement, if not taken in good faith; (b) relating to the purchase and sale by the director or officer of securities in violation of Section 16(b) of the Exchange Act; (c) subject to certain exceptions, in the event of claims initiated or brought voluntarily by the director or officer (rather than by way of defense, counterclaim or cross claim); or (d) for which applicable law prohibits indemnification.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><font style="visibility:hidden;">&#8203;</font></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">The Company also maintains an insurance policy covering the liability of its directors and officers for actions taken in their official capacity. Under this policy, directors and officers are insured, within the limits and subject to the limitations of the policy, against certain expenses in connection with the defense of certain claims, actions, suits or proceedings, and certain liabilities which might be imposed as a result thereof, which may be brought against them by reason of their being or having been directors and officers.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><font style="visibility:hidden;">&#8203;</font></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;text-align:justify;margin:0pt 0pt 12pt 0pt;"><font style="font-weight:normal;">The foregoing contains only a general summary of certain aspects of Delaware law and the Certificate and Bylaws dealing with indemnification of directors and officers as well as the form of indemnification agreement entered into between the Company and its directors and certain officers, and does not purport to be complete. It is qualified in its entirety by reference to the relevant provisions of the DGCL, the Certificate, the Bylaws, and the form of indemnification agreement, the last three of which are on file with the Commission.</font></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">Item&#160;7.

<td class="text">Pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the "Securities Act"), this Registration Statement also covers any additional shares of Common Stock that become issuable pursuant to the 2022 Plan by reason of any stock dividend, stock split, recapitalization, or other similar transaction effected that results in an increase in the number of shares of outstanding Common Stock.

Estimated solely for purposes of calculating the registration fee in accordance with Rule 457(c) and (h) under the Securities Act, and calculated based on the average of the high ($14.91) and low ($14.21) prices of the Common Stock as reported by the New York Stock Exchange on May 19, 2026.
