In addition, the Business Combination Agreement provides for each outstanding option to purchase Signing Day Sports common stock or outstanding warrant to purchase Signing Day Sports common stock that was not previously exercised prior to Closing to be converted into an option or warrant, as applicable, to purchase a number of BlockchAIn common shares equal to the number of shares of Signing Day Sports common stock subject to such option or warrant immediately prior to the Closing multiplied by the Exchange Ratio, with the per share exercise price divided by the Exchange Ratio, and each option to be immediately become fully vested.

As previously disclosed in a Current Report on Form 8-K filed by Signing Day Sports with the SEC on [February 20, 2026](https://www.sec.gov/ix?doc=/Archives/edgar/data/0001898474/000121390026018921/ea0276977-8k425_signing.htm), the information of which is incorporated by reference herein, BlockchAIn determined that the Exchange Ratio would be equal to the fraction obtained by dividing (i) the number that was equal to the last reported sale price of the Signing Day Sports common stock on the last trading day of the Signing Day Sports common stock prior to the Closing, by (ii) 7.5, except that if the Exchange Ratio would have otherwise resulted in a fractional BlockchAIn common share, the Exchange Ratio was rounded up to one (1) with respect to that BlockchAIn common share.
