In March 2016, the Company entered into a Loan and Security Agreement (the “2016 Agreement”) with TriplePoint Venture Growth BDC Corp. (“TriplePoint”), for term loans of up to $20.0 million, secured by substantially all the Company’s assets, excluding its intellectual property. The 2016 Agreement provided for cash advances over a period of forty-two months in three tranches; the first of which was exercised in March 2016, in the amount of $10.0 million. The second draw in the amount of $5.0 million, was exercised in August 2016. These 2016 cash advances were repaid in 2016, 2018, 2019 with the final payment paid in 2021. In connection with the 2016 Agreement, the Company issued TriplePoint warrants to purchase an aggregate of 195,992 shares of Series C redeemable convertible preferred stock with an exercise price equal to the lower of (i) $5.36 per share and (ii) the lowest price per share of the next preferred stock financing offering. The Company determined that the initial fair value of the Series C warrants was $0.2 million (see Note 12 Redeemable Convertible Preferred Stock and related warrants and option).
In November 2017, the 2016 Agreement was amended (the “First Amendment”) to change the interest rate on the existing term loan facility to an annual rate of the prime rate plus 3.75% (however, in no event will the prime rate be less than 3.25%). In addition, the First Amendment modified the prepayment terms such that a prepayment in full would represent the amount equal to the total of all interest payments that would have accrued and been payable from the date of the prepayment at the then existing interest rate, through the stated maturity date of the loan had it remained outstanding and been paid in accordance with its terms. There were no additional fees incurred in connection with the First Amendment.
In March 2019, the Company executed a Second Amendment to the 2016 Agreement (the “Second Amendment”). The Second Amendment provided for new cash advances for up to $50.0 million in four parts, all of which were individual promissory notes. In March, September and December 2020, the Company received cash advances in the amount of $10.0 million each for a total of $30.0 million. The proceeds from the loans were used to finance the Company’s general corporate needs. Each advance under the Second Amendment has its own term, up to forty-two months. At the end of the payment term of each advance, an end-of-term payment equal to 8.0% of the draw would become due. The payments on all cash advances are interest only for various amounts of time, depending on the advance. The interest rates for the March, September and December 2020 draws were based on the prime rate plus 2.90%, prime rate plus 3.70%, and prime rate plus 4.50%, respectively (however, in no event will the prime rate be less than 5.50%). The remaining principal will be due at the end of the term of the applicable advance. The term loan facility contains customary representations and warranties and customary affirmative and negative covenants applicable to the Company, including, among other things, restrictions on indebtedness, liens, investments, sales, transfers or disposals of assets, dividends and other distributions. In connection with the Second Amendment and the related drawdowns during 2019, the Company paid direct fees of $0.3 million and issued a warrant to purchase an aggregate of 161,724 shares of Series D redeemable convertible preferred stock with an exercise price equal to the lesser of (i) $9.275 per share and (ii) the lowest price per share of the next preferred stock financing offering. The Company determined that the initial fair value of the Series D warrants was $0.4 million (see Note 12 Redeemable Convertible Preferred Stock and related warrants and option).
In March 2020, the Company executed the Amended Restated Plain English Growth Capital Loan and Security Agreement with TriplePoint and TriplePoint Capital LLC (the “A&R Loan Agreement”), which amends and restates the 2016 Agreement. In April 2020, the Company exercised its option to receive another cash advance of $10.0 million. In connection with the advance, the Company issued to TriplePoint a warrant to purchase 53,908 shares of the Company’s Series D redeemable
convertible preferred stock with an exercise price equal to the lesser of (i) $9.275 per share and (ii) and the lowest price per share of the next preferred stock financing offering. The Company determined the initial fair value of the warrants at issuance was $0.1 million. The fair value of the warrant is being amortized, as interest expense, over the term of the loan using the effective interest method. The payments on all cash advances are interest only, with interest rates for the March, September, December 2020 and April 2020 draws being based on the prime rate plus 2.90%, prime rate plus 3.70%, prime rate plus 4.50%, and prime rate plus 4.50%, respectively. However, in no event will the prime rate be less than 5.50%. The principal will be due at the end of the term of the respective advance. The A&R Loan Agreement is secured by substantially all the Company’s assets, excluding its intellectual property, which was subject to a negative pledge. The A&R Loan Agreement contains customary representations and warranties and customary affirmative and negative covenants applicable to the Company, including, among other things, restrictions on indebtedness, liens, investments, dividends and other distributions. The A&R Loan Agreement included an option to extend the maturity and prepayment term dates by an additional 12 months if certain criteria were met. In April 2020, the Company met the criteria to extend the maturity and prepayment dates for the four outstanding advances and elected to do so. The A&R Loan Agreement was accounted for as a modification and not an extinguishment as the terms of the Company’s outstanding debt were not substantially different from the original terms. The Company amortizes both the debt issuance fees and the fair value adjustment of the warrants issued in connection with debt issuances as interest expense using the effective interest method over the remaining term of the loan.
In September 2021, the Company executed an amendment to the Amended Restated Plain English Growth Capital Loan and Security Agreement with TriplePoint and TriplePoint Capital LLC (the “A&R Loan Agreement”), which amends and restates the 2016 Agreement. The payments on all cash advances are interest only. The amended A&R Loan Agreement became effective once the registration statement in connection with the initial public offering was declared effective on September 16, 2021. The key provisions of the amendment include: (1) a covenant requiring the maintenance of a $20.0 million cash balance when an event of default exits, (2) change in the interest rate for outstanding term loan to be eight percent (8.00%) per annum on the existing loans, (3) extension of the maturity dates by twenty-four months, (4) change in the prepayment penalties and (5) and a change in the prepayment premium. The principal will be due at the end of the term of the respective advance. The A&R Loan Agreement is secured by substantially all the Company’s assets, excluding its intellectual property, which was subject to a negative pledge. The A&R Loan Agreement contains customary representations and warranties and customary affirmative and negative covenants applicable to the Company, including, among other things, restrictions on indebtedness, liens, investments, dividends and other distributions. The A&R Loan Agreement was accounted for as a modification and not an extinguishment as the terms of the Company’s outstanding debt were not substantially different from the original terms. The Company amortizes the debt issuance costs as interest expense using the effective interest method over the remaining term of the loan. As of December 31, 2021 and December 31, 2020, accrued interest for the end-of term payments was $1.6 million and $1.0 million, respectively. The effective interest rate on debt was 10.75% and 11.44% for the years ended December 31, 2021 and December 31, 2020, respectively. As of December 31, 2021, the Company was in compliance with the covenants set forth in the Amended and Restated Loan Agreement.
Future principal payments on outstanding borrowings as of December 31, 2021 are as follows (in thousands):
