On May 7, 2021, the Company entered into a Loan and Security Agreement (the “Loan”) with Silicon Valley Bank (the “Lender”) for an aggregate principal amount of up to $25.0 million. The Loan bears interest at annual rate equal to the greater of (a) the sum of 1.25% plus the prime rate as reported in The Wall Street Journal and (b) 5.00%. The Loan matures on May 1, 2025. The initial tranche in the amount of $7.5 million was received by the Company on May 7, 2021. In connection with the Loan, the Company issued to the Lender warrants to purchase 91,884 shares of common stock at an exercise price per share equal to $4.76. The warrants are exercisable for a period of ten years from the date of issuance. At the Company’s option, the Company has the ability to draw down the remaining $17.5 million in gross proceeds in two tranches over the next two years based upon the achievement of several milestones in accordance with the terms of the agreement.
We filed a universal shelf registration on Form S-3 with the SEC on January 25, 2019, which was declared effective on February 12, 2019, pursuant to which we registered for sale up to $75.0 million of any combination of our common stock, preferred stock, debt securities, warrants, rights and/or units from time to time and at prices and on terms that we may determine, which we refer to as the 2019 Form S-3.

We make no assurances as to the continued effectiveness of the 2019 Form S-3 or as to any sales under the 2021 Sales Agreement.
