Pursuant to the Underwriting Agreement, FPUSA has entered into a lock-up agreement (the "Lock-Up Agreement") pursuant to which FPUSA has agreed not to sell or transfer any securities of the Issuer held by it for a period of 90 days from June 27, 2025, subject to limited exceptions. In connection with the Offering, FPUSA entered into a share repurchase agreement (the "Share Repurchase Agreement") with the Issuer, pursuant to which the Issuer agreed that it may purchase up to $15.0 million of the shares of the Issuer's Common Stock that are subject to the Offering from the Underwriter at the public offering price as part of its previously announced share repurchase program.
