Description of purchases price   The Company may direct Lincoln Park, at its sole discretion, and subject to certain conditions, to purchase up to 200,000 shares of common stock on any business day (a “Regular Purchase”). The amount of a Regular Purchase may be increased under certain circumstances up to 250,000 shares, provided that Lincoln Park’s committed obligation for Regular Purchases on any business day shall not exceed $2,000,000. In the event we purchase the full amount allowed for a Regular Purchase on any given business day, we may also direct Lincoln Park to purchase additional amounts as accelerated and additional accelerated purchases. The purchase price of shares of common stock related to the future funding will be based on the then prevailing market prices of such shares at the time of sales as described in the 2019 Purchase Agreement.
