Explanation of Responses:

1. Under the Agreement and Plan of Merger, dated January 22, 2024 (the "Merger Agreement"), by and among Inhibrx, Inc. (the "Issuer"), Aventis Inc., a Pennsylvania corporation ("Parent") and wholly owned subsidiary of Sanofi, and Art Acquisition Sub, Inc., a Delaware corporation ("Merger Sub") and wholly owned subsidiary of Parent, following satisfaction or waiver of the closing conditions set forth in the Merger Agreement, on May 30, 2024, Merger Sub merged with and into the Issuer with the Issuer surviving as the surviving company (the "Merger").

2. In the Merger, each of these shares of Common Stock was automatically cancelled, extinguished and converted into the right to receive (i) an amount in cash equal to $30.00, without interest thereon (the "Closing Amount"), plus (ii) one (1) contractual contingent value right ("CVR") representing the right to receive a contingent payment of $5.00, without interest thereon, in cash (the "Milestone Payment"), upon the achievement of certain regulatory milestones ("Milestone") set forth in the Contingent Value Rights Agreement between Parent and Continental Stock Transfer & Trust Company ((i) and (ii) collectively, the "Merger Consideration").

Each of VGI, Mr. Halvorsen, Mr. Ott and Ms. Shabet may be deemed to beneficially own all of the securities reported on this form.

5. Reported amount has been adjusted to reflect the transfer of 3,878,559 shares of Common Stock held directly by DRAGSA 50 LLC to Opportunities Fund, which transfer was exempt from Section 16 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), pursuant to Rule 16a-13 under the Exchange Act.

6. These securities were held directly by Opportunities Fund. Because of the relationship between Opportunities Portfolio GP, Opportunities GP, Opportunities Parent and Opportunities Fund, each of Opportunities Portfolio GP, Opportunities GP and Opportunities Parent may be deemed to beneficially own the securities held directly by Opportunities Fund.

7. These shares of Common Stock were held directly by KAVRA 104. The membership interests of KAVRA 104 are held by Viking Global Opportunities LP and Viking Global Opportunities Intermediate LP. Opportunities GP is the general partner of Viking Global Opportunities LP and Viking Global Opportunities Intermediate LP.

9. The Reporting Persons disclaim beneficial ownership of these securities except to the extent of their pecuniary interest therein, and the inclusion of these securities in this report shall not be deemed an admission of beneficial ownership of the reported securities for purposes of Section 16 of the Exchange Act, or for any other purpose.

10. These warrants were exercisable immediately prior to the Merger, subject to a beneficial ownership limitation (the "Beneficial Ownership Limitation") that prevented the holder from exercising the warrants to the extent that, after giving effect to the issuance of the shares of Common Stock upon exercise of warrants held by the holder, the holder would beneficially own in excess of 9.99% of the shares of Common Stock outstanding.

11. These warrants had no expiration date.

12. In the Merger, these warrants were automatically cancelled and converted into the right to receive the Merger Consideration to which the holder of these warrants would be entitled as a result of the Merger if it held the number of shares of Common Stock for which such warrants were exercisable immediately prior to the Merger, assuming full exercise of such warrants on a cashless basis without regard to the Beneficial Ownership Limitation.
