Agreement, dated as of May 27, 2025, by and among Signing Day Sports, Inc., a Delaware corporation (the &ldquo;Registrant&rdquo;), One
Blockchain LLC, a Delaware limited liability company (&ldquo;One Blockchain&rdquo;), BlockchAIn Digital Infrastructure, Inc., a Delaware
corporation (&ldquo;BlockchAIn&rdquo;), BCDI Merger Sub I Inc., a Delaware corporation and a wholly-owned subsidiary of BlockchAIn (&ldquo;Merger
Sub I&rdquo;), and BCDI Merger Sub II LLC, a Delaware limited liability company and a wholly-owned subsidiary of BlockchAIn (&ldquo;Merger
Sub II&rdquo;), as amended by Amendment No. 1 to the Business Combination Agreement, dated as of November 10, 2025, between the Registrant
and One Blockchain, as amended by Amendment No. 2 to the Business Combination Agreement, dated as of December 21, 2025, among the Registrant,
One Blockchain, BlockchAIn, Merger Sub I, and Merger Sub II (as amended, the &ldquo;Business Combination Agreement&rdquo;), on March 16,
2026 (the &ldquo;Closing Date&rdquo;), Merger Sub I merged with and into the Registrant, with the Registrant continuing as the surviving
corporation and a direct wholly-owned subsidiary of BlockchAIn, and Merger Sub II merged with and into One Blockchain, with One Blockchain
continuing as the surviving limited liability company and a direct wholly-owned subsidiary of BlockchAIn. In accordance with the Business
Combination Agreement, on the Closing Date, all outstanding shares of common stock, par value $0.0001 per share, of the Registrant (&ldquo;Signing
Day Sports Common Stock&rdquo;), were exchanged for the right to receive a certain fraction (the &ldquo;Exchange Ratio&rdquo;) of one
(1) registered common share, $0.0001 par value per share, of BlockchAIn (&ldquo;BlockchAIn common shares&rdquo;). In addition, 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 the Closing Date was 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
Date multiplied by the Exchange Ratio, with the per share exercise price divided by the Exchange Ratio, and each option immediately became
fully vested.&nbsp;The Exchange Ratio was&nbsp;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
Date, by (ii) 7.5, or 0.09334, 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.</P>
