Prepaid Warrant issued by Boumarang Inc. to the Company

THIS COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, T Stamp Inc. or its assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the Issuance Date as set forth above and on or prior to the tenth annual anniversary of the Issuance Date (the “Termination Date”) but not thereafter, to subscribe for and purchase from Boumarang Inc., (the “Company”), 5,000,000 (five million) shares of Common Stock, par value $0.0001 per share (the “Common Stock”) of the Company (as subject to adjustment hereunder, the “Warrant Shares”). The purchase price of the Common Stock has been prepaid in full by the grant of a patent license valued at $5,000,000, entered between the parties on this date; therefore, no additional consideration is payable to exercise the Warrant. For the avoidance of doubt, the Exercise Price shall be $0.00 per share of Common Stock under this Warrant.

1.Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time before the Termination Date by delivery of written notice to the Company by email to admin@boumarang.com. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required.

2.Notwithstanding anything herein to the contrary (although the Holder may surrender the Warrant to, and receive a replacement Warrant from, the Company), the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is delivered to the Company.

3.Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall lower the outstanding number of Warrant Shares purchasable hereunder by an amount equal to the applicable number of Warrant Shares purchased.

4.The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to a Notice of Exercise within one (1) Trading Day of delivery of such notice.

5.By accepting this Warrant, the Holder and any assignee acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

6.Certificates for shares purchased hereunder shall be transmitted by the Company’s then- engaged transfer agent (the “Transfer Agent”) to the Holder by crediting the account of the Holder’s broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and there is an effective registration statement permitting the issuance of the Warrant Shares to, or resale of the Warrant Shares, by the Holder and otherwise by physical delivery to the address specified by the Holder in the Notice of Exercise by the date that is two (2) Trading Days after the delivery to the Company of the Notice of Exercise, (such date, the “Warrant Share Delivery Date”). The Warrant Shares shall be deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes as of the date the Warrant has been exercised, with payment to the Company of the Exercise Price and all taxes required to be paid by the Holder, if any, prior to the issuance of such shares, having been paid.

7.In the event that the Company fails for any reason to effect delivery of the Warrant Shares by the Warrant Share Delivery Date, the Holder may revoke all or part of the relevant Warrant exercise by delivery of a notice to such effect to the Company, whereupon the Company and the Holder shall each be restored to their respective positions immediately prior to the exercise of the relevant portion of this Warrant.

8.If this Warrant has been exercised in part, the Company shall, upon surrender of this Warrant certificate, at the request of the Holder, deliver to the Holder a new Warrant evidencing the Holder's rights to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.

9.Closing of Books. The Company will not close its shareholder books or records in any manner that prevents the timely exercise of this Warrant, pursuant to the terms hereof.

10.Adjustments for Stock Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for the avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of

shares, then both the Exercise Price and the number of shares of Common Stock issuable upon the Exercise of this Warrant shall each be appropriately and proportionally adjusted to reflect any stock dividend, stock split, a combination of shares, reclassification, recapitalization or other similar event affecting the number of outstanding shares of Common Stock (or such other stock or securities).

11.Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin-off, reclassification, corporate rearrangement, scheme of arrangement, or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution.

The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

13.Subject to compliance with all applicable securities laws, this Warrant may be divided or combined with other Warrants upon presentation hereof to theCompany via email, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney and the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice.

17.This Agreement shall be solely and exclusively construed and enforced in accordance with, and all questions concerning its construction, validity, interpretation, and performance shall be governed solely and exclusively by the laws of the State of Delaware without giving effect to any choice of law or conflict of law provision or rule that would cause the application of the laws of any jurisdiction other than Delaware.

18.The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, will have restrictions upon resale imposed by state and federal securities laws.

19.No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights,

powers, or remedies.
