What is the deadline for receipt of director nominations and stockholder proposals to be presented at the next annual meeting of stockholders? 

In order for any stockholder proposal submitted pursuant to Rule 14a-8 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), to be included in the Company’s Proxy Statement to be issued in connection with the 2024 Annual Meeting of Stockholders, such stockholder proposal must be received by the Company no later than June 12, 2024. Any such stockholder proposal submitted, including any accompanying supporting statement, may not exceed 500 words, as per Rule 14a-8(d) of the Exchange Act. Any director nominations or stockholder proposals submitted outside the processes of Rule 14a-8 promulgated under the Exchange Act, which a stockholder intends to bring forth at the Company’s 2024 annual meeting of stockholders, will be untimely unless it is received between July 13, 2024 and August 12, 2024 in accordance with the Company’s Amended and Restated Bylaws (the “Bylaws”). In order for stockholders to give timely notice of nominations for directors for inclusion on a universal proxy card in connection with the 2024 annual meeting of stockholders, notice must be submitted no later than September 11, 2024 and include all of the information required by Rule 14a-19 under the Exchange Act. Any changes to such dates will be disclosed in our periodic reports on Form 10-Q or Form 10-K, or current reports on Form 8-K, filed with the SEC. Any such request should be directed to the Company’s Secretary at 1700 Pacific Avenue, Suite 2900, Dallas, Texas, 75201
