a Delaware corporation (“ Pubco”), Parataxis Holdings LLC, a Delaware limited liability company (the “Company”)
and certain accredited investors (the “ Preferred Equity Investors”) entered into agreements (the “ Preferred
Equity Subscription Agreements”) on August 6, 2025, pursuant to which, the Company agreed to issue, and the Preferred Equity
