Other Commitment	Pursuant to the Partnership Agreement, the Company agreed to issue Tenant 500,000 shares its common stock per month for each rented Space (the “Monthly Issuances”), and to also issue an additional number of shares of common stock annually equal to 100% of the Monthly Issuances for the applicable year (the “Annual Issuances,” and together with the Monthly Issuances, collectively, the “Issuances”). Further, pursuant to the Partnership Agreement, the Company provided Tenant with the option (the “Option”) to lend MGT up to $1 million evidenced by a convertible promissory note that is convertible into 25% of the Company’s outstanding common stock, assuming all $1 million is lent, on a pro-forma, post-issuance basis (the “Note”), together with an accompanying warrant to purchase 180% of the shares of common stock underlying the Note (the “Warrant”). The terms of the Note and Warrant would be substantially similar to the September 2022 Note and accompanying warrants that were issued by the Company along with that note. If the Option is exercised, the parties may elect to substitute the $1 million purchase price, in whole or in part, with equipment and infrastructure improvements to enable the Company to have access to up to an additional 10 MWs of electricity to the facility’s currently available electrical power capacity.
