As a result of the Business Combination, Pubco will issue (i) up to 25,455,000 shares of Class A common stock, par value $0.0001 per share, of Pubco ("Pubco Class A Common Stock") to the shareholders of SilverBox Corp IV, a Cayman Islands exempted company ("SilverBox"), including up to (x) 20,000,000 shares of Pubco Class A Common Stock to SilverBox's public shareholders, and (y) 5,455,000 shares of Pubco Class A Common Stock to SilverBox Sponsor IV LLC (the "Sponsor"); and (ii) 6,818,334 warrants of Pubco to be issued to the warrantholders of SilverBox and 6,818,334 shares of Pubco Class A Common Stock issuable upon the exercise of such warrants including (x) 6,666,667 warrants to be issued to SilverBox's public warrantholders, and (y) 151,667 warrants to be issued to the Sponsor. (1.b) Pursuant to Rule 416(a), there are also being registered an indeterminable number of additional securities as may be issued to prevent dilution resulting from share subdivisions, share dividends or similar transactions. (1.c) Represents an aggregate of 25,455,000 shares of Pubco Class A Common Stock issuable in accordance with Note 1.a above. (1.d) Estimated solely for purposes of calculating the registration fee in accordance with Rule 457(c) and Rule 457(f)(1) under the Securities Act of 1933, as amended (the "Securities Act"). The proposed maximum aggregate offering price is equal to the product obtained by multiplying US$10.46, which represents the average of the high and low stock price of SilverBox on the NYSE on August 26, 2025 (such date being within five business days of the date that this registration statement was first filed with the U.S. Securities and Exchange Commission), by 25,455,000 shares of Pubco Class A Common Stock issuable to the shareholders of SilverBox in connection with the Business Combination, as described in Note 1.a above.

(2.b) Estimated solely for purposes of calculating the registration fee in accordance with Rule 457(i) and Rule 457(f)(2) of the Securities Act. Parataxis is a private company with no market existing for its securities.
