, we encourage you to submit your proxy as soon as possible to make sure that your shares are represented at the Special Meeting. Stockholders of record at the close of business on [●], 2025, the record date for the Special Meeting, are entitled to vote at the Special Meeting or any adjournment or postponement thereof. Whether or not you expect to virtually attend the Special Meeting online, please submit a proxy to vote your shares to ensure your representation and the presence of a quorum at the Special Meeting. If you are a stockholder of record, you may submit a proxy to vote your shares prior to the Special Meeting online by visiting [●], by telephone using the number located on the enclosed proxy card and following the recorded instructions, or by completing, signing, dating, and returning the proxy card accompanying these proxy materials. Your vote is important regardless of the number of shares you own. If you mail your proxy card or submit a proxy by telephone or online and then decide to attend the Special Meeting and vote your shares online during the Special Meeting, you may still do so. Your proxy is revocable in accordance with the procedures set forth in the proxy statement. If your shares are held in “street name,” that is, held for your account by a bank, broker or other nominee, you will receive instructions from the bank, broker or other nominee that you must follow for your shares to be voted. Stockholders that own shares in “street name” must demonstrate proof of beneficial ownership to virtually attend the Special Meeting and must obtain a legal proxy from their bank, broker or other nominee to vote during the Special Meeting. Further information about how to attend the Special Meeting online, vote your shares and submit questions is included in the accompanying proxy statement.

If you have more questions about this proxy statement and the proposals to be voted on at the Special Meeting or how to submit your proxy, or if you need additional copies of this proxy statement or the enclosed proxy card or voting instructions, please contact our proxy solicitor below: SODALI & CO 430 Park Avenue, 14th Floor New York, NY 10022 Email: AAADI@investor.sodali.com Banks and Brokers Call: (203) 658-9400 Stockholders Call Toll Free: (800) 662-5200
