On May 28, 2010, the Company entered into a loan and security agreement with Hercules Capital Inc. and certain of its affiliates (the “First Loan Agreement”). The First Loan Agreement was subsequently amended in March 2012 (the “2012 Amendment”), September 2014 (the “2014 Amendment”) and May 2016 (the “2016 Amendment”). Amounts borrowed under the 2012 Amendment were repaid in full in 2015. In December 2017, the Company entered into an amended and restated loan and security agreement (the “2017 Loan Agreement”) with Hercules Funding III, LLC and Hercules Capital, Inc. (collectively “Hercules”).

Pursuant to the 2014 Amendment, the Company received additional loan proceeds from Hercules in the amount of $10.0 million and paid an end-of-term payment, in the approximate amount of $0.5 million, on January 2, 2018 as scheduled. The Company incurred approximately $0.2 million in loan issuance costs paid directly to Hercules, which were offset against the loan proceeds and are accounted for as a loan discount.

Pursuant to the 2016 Amendment, the Company received additional loan proceeds from Hercules, in an aggregate amount of $10.0 million, in installments of $5.0 million in each of May 2016 and June 2017, which increased the aggregate outstanding principal balance under the First Loan Agreement to $20.0 million. The Company paid an end-of-term payment, in the amount of $0.3 million, on December 1, 2019 as scheduled. The Company incurred approximately $0.1 million in loan issuance costs paid directly to Hercules, which were offset against the loan proceeds and are accounted for as a loan discount. The 2016 Amendment included a financial covenant that required the Company to maintain an unrestricted cash position (defined as cash and liquid cash, including marketable securities) greater than or equal to $10.0 million through the date of completion of the Company’s TIVO-3 trial, with results that were satisfactory to Hercules. Principal payments were scheduled to commence on January 1, 2018 and the loan was scheduled to mature on December 1, 2019.

In connection with the 2016 Amendment, Hercules also received an option, subject to the Company’s written consent, not to be unreasonably withheld, to purchase, either with cash or through conversion of outstanding principal under the loan, up to $2.0 million of equity of the Company sold in any sale by the Company to third parties of equity securities resulting in at least $10.0 million in net cash proceeds to the Company, subject to certain exceptions.

In December 2017, the Company entered into the 2017 Loan Agreement to refinance the Company’s existing loan facility with Hercules and to retire the $20.0 million in secured debt then-outstanding under the First Loan Agreement. Per the terms of the 2017 Loan Agreement, the new $20.0 million loan facility has a 42-month maturity from closing, no financial covenants, a lower interest rate and an interest-only period of no less than 12 months, which could be extended up to a maximum of 24 months, assuming the achievement of specified milestones relating to the development of tivozanib. Per the 2017 Loan Agreement, Hercules did not receive any warrants to purchase shares of the Company’s common stock and no longer has the option, subject to the Company’s written consent, to participate in its future equity financings up to $2.0 million through the purchase of the Company’s common stock either with cash or through the conversion of outstanding principal under the loan.

Per the 2017 Loan Agreement, the loan maturity date was revised from December 2019 to July 2021. The Company was not required to make principal payments until February 1, 2019, at which time the Company would have been required to make 29 equal monthly payments of principal and interest, in the approximate amount of $0.8 million, through July 2021. An additional end-of-term payment of approximately $0.8 million is due on July 1, 2021. The financial covenant per the 2016 Amendment to maintain an unrestricted cash position greater than or equal to $10.0 million through the date of completion of the Company’s TIVO-3 trial with results that are satisfactory to Hercules has been removed. Per the 2017 Loan Agreement, the interest rate decreased from 11.9% to 9.45%. The Company incurred approximately $0.1 million in loan issuance costs paid directly to Hercules, which are accounted for as a loan discount. The 2017 Loan Agreement was accounted for as a loan modification in accordance with ASC 470-50.

The Company must make interest payments on the principal balance of the loan each month it remains outstanding. Per annum interest is payable on the loan balance at the greater of 9.45% and an amount equal to 9.45% plus the prime rate minus 4.75%, as determined daily, provided however, that the per annum interest rate shall not exceed 15.0%. In 2018, the interest rate increased to 9.70%, 9.95% and 10.20% in June 2018, September 2018 and December 2018, respectively, due to corresponding increases in the prime rate. In 2019, the interest rate decreased to 9.95%, 9.70% and 9.45% in August 2019, September 2019 and October 2019, respectively, due to corresponding decreases in the prime rate. The interest rate as of March 31, 2020 was 9.45%.

The interest-only period could be extended by two 6-month deferrals of principal payments upon the achievement of specified milestones relating to the development of tivozanib, subject to confirmation by Hercules at its reasonable discretion.

In November 2018, Hercules granted the first 6-month extension of the interest-only period. Accordingly, this resulted in the deferment of principal payments until August 1, 2019, at which time the Company resumed making 24 equal monthly payments of principal and interest, in the approximate amount of $0.9 million through July 2021. The outstanding principal balance as of March 31, 2020 was approximately $13.8 million.

The unamortized discount to be recognized over the remainder of the loan period was approximately $0.3 million and $0.4 million as of March 31, 2020 and December 31, 2019, respectively.

The loans are secured by a lien on all the Company’s personal property (other than intellectual property), whether owned or acquired after the date of the First Loan Agreement. The 2017 Loan Agreement defines events of default, including the occurrence of an event that results in a material adverse effect upon the Company’s business operations, properties, assets or condition (financial or otherwise), its ability to perform its obligations or upon the ability of the lenders to enforce any of their rights or remedies with respect to such obligations, or upon the collateral under the 2017 Loan Agreement, the related liens or the priority thereof. As of March 31, 2020, the Company was in compliance with all loan covenants, Hercules has not asserted any events of default and the Company does not believe that there has been a material adverse change as defined in the 2017 Loan Agreement.

The Company has determined that the risk of subjective acceleration under the material adverse events clause is remote and therefore has classified the outstanding principal in current and long-term liabilities based on the timing of scheduled principal payments.

Future minimum payments under the loans payable outstanding as of March 31, 2020 are as follows (amounts in thousands):
