Subscription Agreements

On June 6, 2020, the Company entered into a subscription agreement with an accredited investor for the issuance of 1.3 million shares of the Company's common stock in a private placement. The shares of common stock were issued as part of a transaction in settlement of an outstanding obligation of the Company to the accredited investor, in which (i) the Company agreed to make certain cash payments, (ii) the Company issued the 1.3 million shares of common stock in exchange for the accredited investor's agreement to cancel $0.3 million of the outstanding obligation and (iii) the accredited investor agreed to cancel an additional portion of the amount owed by the Company representing a discount of $0.2 million.

On April 22, 2020, the Company entered into a subscription agreement with an accredited investor for the sale of 1,000 shares of the Company's common stock in a private placement for an aggregate offering price of $395. This private placement constituted a Dilutive Issuance (as defined in Note 11) and resulted in adjustments to the Series A Warrants.
