16. SUBSEQUENT EVENTS

On March 12, 2020, we and LPC entered into Amendment No. 1 to the Purchase Agreement, or the Amendment, pursuant to which the term of the Purchase Agreement was extended from 30 months to 54 months and the number of shares of common stock that we may direct LPC to purchase from time to time pursuant to a Regular Purchase (as defined in the Purchase Agreement) was increased from 80,000 shares of common stock to 150,000 shares of common stock. Minimum closing stock price requirements were also removed for Regular Purchases and Accelerated Purchases (each as defined in the Purchase Agreement). In connection with the Amendment, we agreed to pay to LPC $0.1 million as an expense reimbursement.
