Note 13. Warrants

In connection with certain of its redeemable convertible preferred stock issuances, debt agreements, convertible debt and other financing arrangements, the Company has issued warrants for shares of its common stock and various issues of its redeemable convertible preferred stock which have since been converted to common stock warrants.

In connection with the Securities Purchase Agreement (see Note 14), the Company issued and sold pre-funded warrants exercisable for an aggregate of 360,779 shares of common stock. The total exercise price of the pre-funded warrants is $9.75 per share, $9.60 of which was pre-funded and paid to the Company upon issuance of the pre-funded warrants. The remaining exercise price of the pre-funded warrants is $0.15 per share. In March 2020, 211,784 of the pre-funded warrants were exercised for proceeds of $31,768. In June 2021, the remaining 148,995 pre-funded warrants were exercised on a cashless, net exercise basis, resulting in the issuance of 144,881 shares of common stock.

In connection with the SVB Term Loan (see Note 8), the Company granted to SVB a warrant to purchase up to 42,894 shares of the Company’s common stock at a purchase price of $11.6565 per share. The warrant will expire on June 24, 2030 and may be exercised for cash or at the election of the holder on a cashless, net exercise basis.
