Explanation of Responses:

( 1 )The Reporting Person became entitled to receive the reported shares pursuant to the Agreement and Plan of Reorganization and Merger, dated as of March 15, 2021, as amended by Amendment No. 1 to Agreement and Plan of Reorganization and Merger, dated as of August 6, 2021 (the "Merger Agreement"), by and among LGL Systems Acquisition Corp., LGL Systems Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of LGL, and IronNet Cybersecurity, Inc., a Delaware corporation (the "Business Combination"), as described in the Reporting Person's Form 4 filed with the Securities and Exchange Commission on August 30, 2021 (the "Prior Report"). ( 2 )The Merger Agreement provided that the Reporting Person would receive additional shares of the Issuer's common stock, for no additional consideration, if the volume-weighted average closing sale price of one share of the Issuer's common stock was equal to or greater than $13.00 for any ten consecutive trading days occurring after the closing date of the Business Combination. The tenth consecutive trading day was September 10, 2021. Therefore, the Reporting Person's right to receive the reported shares became fixed and irrevocable as of that date in exchange for the same securities of IronNet Cybersecurity, Inc. surrendered at the time of the Business Combination as described in footnote (4) of the Prior Report.
