On March 30, 2020, Edible Garden Corp. (“Edible Garden”), a wholly-owned subsidiary of Terra Tech Corp. (the “Company”), entered into and closed an Asset Purchase Agreement (the “Purchase Agreement”) with Edible Garden Incorporated (the “Purchaser”), pursuant to which Edible Garden sold and the Purchaser purchased substantially all of the assets of Edible Garden (the “Business”). The consideration paid for the Business included two option agreements to purchase up to a 20% interest in the Purchaser for a nominal fee. The first option gives the Company the right to purchase a 10% interest in the Purchaser for one dollar at any time between the one and five-year anniversary of the transaction, or at any time should a change in control event or public offering occur. The second option gives the Company the right to purchase an additional 10% interest in the Purchaser for one dollar at any point prior to the five-year anniversary of the transaction. The second option is automatically terminated upon payment in full of the $3.00 million secured promissory note.

Management estimated the fair value of the options using the Black-Scholes model, utilizing level 3 inputs that included the stock price, annual volatility, and the probability the second option will be terminated due to repayment of the secured promissory note. The estimated fair value of the options was $0.33 million as of March 31, 2021. The options are included in the “Investments” line within the consolidated balance sheet.
