On December 8, 2020, the Company entered into a common stock purchase agreement ("SPA") with Tumim Stone Capital, LLC ("Tumim") to issue and sell up to $10.0 million in shares of the Company's common stock. The SPA provides, among other things, that the Company may direct, every three trading days, Tumim to purchase a number of shares not to exceed an amount determined based upon the trading volume and stock price of the Company’s shares.

Such sales of common stock by the Company will be subject to certain limitations, and may occur from time to time, at the Company's sole discretion till December 31, 2021. The Company determined that the fair value of the put option is zero as the shares will be issued at a discount and settled within one business day. During the year ended December 31, 2020, the Company sold 450,000 shares of common stock pursuant to the SPA and recognized proceeds of $0.2 million. The Company issued 185,454 shares of common stock to Tumim as commitment fee in connection with entering into the SPA. In addition, the Company incurred offering cost of $0.3 million.
