3.02 Unregistered Sales of Equity Securities

Between

October 13, 2026 and October 19, 2026, Tessera Defense and Homeland Security Inc. (“Tessera” or the “Company”)

issued 6,529,494 restricted shares of common stock to Mandragola Ltd. (the “Warrant Shares”) issued in four tranches upon

cashless exercises by Mandragola of portions of the five-year warrant issued (the “DFSL Warrant”) to Mandragola on April

13, 2026 in connection with the Company’s acquisition of a 60% interest in Dr. Frucht Systems Ltd. (“DFSL”).

The

DFSL Warrant is exercisable on a cashless basis for such number of shares of common stock equal to the Black-Scholes value of a Warrant

Share, as set out in the DFSL Warrant, using the lower of the closing bid prices of the Company’s common stock in the two trading

days preceding the exercise, subject to a floor of $0.10 per share (as adjusted). The DFSL Warrant may not be exercised to the extent

that Mandragola, together with its affiliates, would beneficially own more than 9.99% of the Company’s outstanding common stock

after the exercise.

The

Warrant Shares were issued in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933,

as amended (the “Securities Act”). The shares are “restricted securities” within the meaning of Rule 144 under

the Securities Act.

of October 19, 2026, after giving effect to the issuances described above, the Company had 20,663,177 shares of common stock outstanding.
