On April 13, 2018, the Company entered into a purchase and sale agreement with Andre Buys, ("Buys"), the Company's Chief Technology Officer ("CTO"), pursuant to which the Company purchased certain intellectual property relating to air and/or gas fired long guns or pistols, including pump action launchers and munitions used with such pistols and long guns, including self-stabilizing shaped or “finned” rounds. As consideration for the Buys Portfolio, the Company paid Buys $0.1 million, and incurred $0.01 million in legal costs to transfer these patent rights.

Pursuant to an amendment of the Agreement effective December 18, 2019, the Company made two additional payments to Buys totaling of $0.8 million, consisting of the Second Payment of $0.7 million through the issuance of 386,681 shares of common stock and Final Payment of $0.08 million in cash. The Final Payment was paid during the quarter ended May 31, 2020. Buys no longer retains any reversion rights or security interests in the Buys Portfolio. These patents rights have a maximum life of 20 years, expiring on various dates beginning from November 2033 to 2038, and are amortized on a straight-line basis over a period of 15 years.
