Unless defined herein, capitalized terms have the meanings given to them in that certain Securities Purchase Agreement (the “Securities Purchase Agreement”), dated November 25, 2019, by and among the Company and the purchasers identified on the signature pages thereto (the Purchasers”), relating to the issuance and sale by the Company of the Debenture.
