Explanation of Responses:
1. The stock options are fully executed and received in accordance with the terms of the Business Combination Agreement (the "Business Combination Agreement"), dated as of September 6, 2023, by and among the Issuer, Tigre Merger Sub, Inc. and Zapata Computing, Inc. ("Private Zapata"), in exchange for an option to acquire 75,000 shares of common stock of Private Zapata.
2. The Notes mature on the one-year anniversary of the issuance date (subject to acceleration upon the occurrence of certain customary events of default or a change of control) and bear 10% per annum interest. The Notes convert automatically upon the Company's completion of a securities offering resulting in gross proceeds of at least $5 million. The Notes and Warrants were sold as units for which the total purchase price paid by the Reporting Person was $100,000.
3. At any time when a registration statement registering the resale of shares issuable upon exercise of the Warrants is not effective, the Warrants can be exercised cashlessly. The Notes and Warrants were sold as units for which the total purchase price paid by the Reporting Person was $100,000.
4. The Reporting Person is the trustee for the William E. Klitgaard Trust.
Remarks:
The original Form 3 was filed at a time when the Issuer was subject to Section 12(b) of the Securities Exchange Act of 1934. That registration was subsequently withdrawn. The Issuer became subject to the reporting requirements under Section 12(g) of the Securities Exchange Act of 1934 on May 1, 2026. The Form 3 is now being amended to comply with the reporting requirements under Section 12(g).
