Commitments	Commitments (a)R&D Commitments (i) Ginkgo. On September 4, 2018, the Company announced an R&D partnership with Ginkgo to develop scalable and consistent production of eight target cannabinoids, including THC, CBD and a variety of other lesser known and rarer cannabinoids. As part of this partnership, Cronos Group has agreed to issue up to 14,674,903 common shares of the Company (aggregate value of approximately $100,000 as of July 17, 2018 assuming all milestones are met) (collectively the “Ginkgo Equity Milestones”) in tranches and $22,000 in cash subject to Ginkgo’s achievement of certain milestones and to fund certain R&D expenses, including foundry access fees. (ii) Technion. On October 15, 2018, the Company entered into a sponsored research agreement with the Technion Research and Development Foundation of the Technion – Israel Institute of Technology (“Technion”). Research will be focused on the use of cannabinoids and their role in regulating skin health and skin disorders. The Company has committed to $1,784 of research funding over a period of three years. An additional $4,900 of cash payments will be paid to Technion upon the achievement of certain milestones. (b)Altria Consulting Services On February 18, 2019, the Company entered into an agreement with a wholly owned subsidiary of Altria (which agreement was subsequently amended and restated to substitute Altria Pinnacle as a party thereto), to receive strategic advisory and project management services from Altria Pinnacle (the “Services Agreement”). Pursuant to the Services Agreement, the Company will pay Altria Pinnacle a monthly fee equal to the product of one hundred and five percent (105%) and the sum of: (i) all costs directly associated with the services incurred during the monthly period, and (ii) a reasonable and appropriate allocation of indirect costs incurred during the monthly period. The Company will also pay all third-party direct charges incurred during the monthly period in connection with the services, including any reasonable and documented costs, fees and expenses associated with obtaining any consent, license or permit. The Services Agreement will remain in effect until terminated by either party. (c)Use of Publicity Rights in Brand Development On December 23, 2019, the Company issued 856,017 restricted common shares to an accredited investor in a private placement (“Private Placement – 2019”) in reliance on Section 4(a)(2) of the Securities Act of 1933 in connection with the use of certain publicity rights in brand development. One-third of such common shares vested on January 31, 2020 with the remaining shares vesting in two equal installments on June 23, 2021, and December 23, 2022. The issuance did not involve a public offering and was made without general solicitation or advertising. The total fair value of the consideration paid for the issuance of such common shares was approximately $6,000. The fair value of the shares was calculated using the ten-day volume weighted average price per share of the Company’s common shares on Nasdaq. Additional restricted common shares are issued when certain performance milestones are achieved: (i) First Performance Issuance: if, prior to December 23, 2022, the product line generates at least $50,000 in net revenue, additional common shares with an aggregate value of $1,000 will be issued. (ii) Second Performance Issuance: if, prior to December 23, 2022, the product line generates at least $100,000 in net revenue, additional common shares with an aggregate value of $1,000 will be issued (together with the First Performance Issuance noted above). The number of common shares that would be issued upon achieving the foregoing milestones will be determined based on the ten-day volume weighted average price per share of the Company’s common shares on Nasdaq as of the trading day immediately prior to the date of filing with the SEC of the Company’s audited year-end financial statements for the first fiscal year during which such milestones are achieved. (d)Take or Pay Supply Agreement In January 2020, the Company entered into a take or pay supply agreement with a supplier of dried cannabis flower. The Company agreed to purchase a minimum of approximately C$1,734 ($1,290) of dried cannabis flower over 6 months from the date of the agreement and, subject to the supplier’s satisfaction of certain conditions and the availability of additional product, potentially up to a maximum of approximately C$4,284 ($3,188) over 6 months from the date of the agreement. As at June 30, 2020, the Company is committed to purchase approximately C$1,230 ($906) of dried cannabis flower remaining under this agreement which, due to delays in deliveries from the supplier, are expected to be made during the remainder of 2020.
