The March 2024 Credit Agreement is not convertible into securities of the Issuer or into any other securities. The March 2024 Credit Agreement is further described in the Issuer’s Form 8-K filed with the SEC on March 4, 2024.

The foregoing descriptions of the terms of the March 2024 Credit Agreement, of the First Amendment to July 2023 Credit Agreement and of the Second Amendment to Convertible Credit Agreement do not purport to be complete and are qualified in their entirety by the full texts of such agreements, copies of which are filed as Exhibits 10.1, 10.2 and 10.3, respectively, to the Form 8-K of the Issuer filed with the SEC on March 4, 2024.
