On August 6, 2021, the Company entered into a Loan and Security Agreement with SVB, or the Loan and Security Agreement. The Loan and Security Agreement provided for an initial term loan of $25.0 million funded at the closing, with an additional tranche of $25.0 million available if certain funding and clinical milestones were met by August 31, 2022. On December 28, 2021, the Company entered into a First Amendment, (the “Amendment”) to the Loan and Security Agreement (the “Amended Loan and Security Agreement”). Under the terms of the Amended Loan and Security Agreement, the SVB Facility was modified to eliminate the additional $25.0 million tranche, which remained unfunded, leaving only the initial $25.0 million as the full amount available under the SVB Facility. The SVB Facility bears interest at a floating rate per annum on outstanding loans, payable monthly, at the greater of (a) 7.75% and (b) the current published U.S. prime rate, plus a margin of 4.5%. As of December 31, 2021, interest on the outstanding loans was 7.75%. The Amended Loan and Security Agreement provides for an interest-only period which extends through August 31, 2022 and may be automatically extended through August 31, 2023 if, on or prior to August 31, 2022, SVB receives evidence satisfactory to it, confirming that the Company has (i) received at least $50.0 million in net cash proceeds from the sale of the Company’s equity securities after the date of the Amended Loan and Security Agreement, on terms and conditions acceptable to SVB, and (ii) achieved positive data in the first cohort of the Library TCR-T Trial endorsed by an independent safety monitoring committee as a safe dose to proceed (together, the “Amended Milestones”). After the interest-only payment period, aggregate outstanding borrowings are payable in twelve consecutive, equal monthly installments of principal plus accrued interest.

All outstanding principal and accrued and unpaid interest under the SVB Facility and all other outstanding obligations under the Amended Loan and Security Agreement are due and payable on August 1, 2023; however, if the Company achieves the Amended Milestones on or prior to August 31, 2022, then the maturity will be automatically extended to August 1, 2024. In addition to the payment of the outstanding principal plus accrued interest due, the Company will also owe SVB 5.75% of the original principal amounts borrowed as a final payment. We are permitted to make up to two prepayments, subject to the prepayment premium, of the SVB Facility, each payment of at least $5.0 million. Such prepayment premium would be 3.00% of the principal amount of the SVB Facility if prepaid prior to the first anniversary of the effective date, 2.00% of the principal amount of the SVB Facility if prepaid on or after the first anniversary of the effective date but prior to the second anniversary of the effective date and 1.00% of the principal amount of the SVB Facility if prepaid on or after the second anniversary of the effective date but prior to the maturity date. No amount that has been repaid may be reborrowed.

The Loan and Security Agreement required the Company to cash collateralize half of the sum of the outstanding principal amount of the term loans, plus an amount equal to 5.75% of the original principal amount of any portion of the SVB Facility actually extended, if the Company failed to achieve certain fundraising milestones on or prior to December 31, 2021.

The Amended Loan and Security Agreement revised the Company's cash collateralization obligation to require the Company to cash collateralize half of the sum of only the then-outstanding principal amount of the SVB Facility, plus an amount equal to 5.75% of the original principal amount of the SVB Facility if the Company does not achieve the Amended Milestones on or prior to August 31, 2022. In the event a cash collateralization were to occur, so long as no event of default has occurred and, after subtracting the eighth scheduled payment of principal and interest on the SVB Facility, the sum of the aggregate of outstanding principal and accrued and unpaid interest, plus the final payment, is equal to or less than $9,770,933, then, within ten business days of the date of receipt of the eighth scheduled payment of principal and interest on the SVB Facility, SVB will release $2.5 million from the collateral account, so long as the balance in the collateral account after the release would equal or exceed $10.0 million. If no event of default has occurred and, after subtracting the tenth scheduled payment of principal and interest on the SVB Facility, the sum of the aggregate of outstanding principal and accrued and unpaid interest, plus the final payment, is equal to or less than $5,604,167, then, within ten business days of the date of receipt of the tenth scheduled payment of principal and interest on the SVB Facility, SVB will release a further $4.0 million from the collateral account, so long as the balance in the collateral account after the release would equal or exceed $6.0 million. The SVB Facility and related obligations under the Amended Loan and Security Agreement are secured by substantially all of the Company’s properties, rights and assets, except for its intellectual property (which is subject to a negative pledge under the Amended Loan and Security Agreement). In addition, the Amended Loan and Security Agreement contains customary representations, warranties, events of default and covenants.

In connection with its entry into the Loan and Security Agreement, the Company issued to SVB warrants to purchase (i) up to 432,844 shares of the Company’s common stock, par value $0.001 per share in the aggregate, and (ii) up to an additional 432,842 shares of common stock, in the aggregate, in the event the Company achieves certain clinical milestones, in each case at an exercise price per share of $2.22.

In connection with the entry into the Amendment, the Company amended and restated the warrants issued to SVB. As amended and restated, the warrants are for up to 649,615 shares of the Company's common stock, in the aggregate, at an exercise price per share of $1.16, or the SVB Warrants. The SVB Warrants expire on August 6, 2031.

The issuance costs for the Loan and Security Agreement, including the Amended Loan and Security Agreement, were approximately $1.2 million and primarily related to the warrants issued to SVB, which will be amortized into interest expense over the period to August 1, 2023. Interest expense, including the amortization of issuance costs, was $1.2 million for the year ended December 31, 2021.

The fair value of the Amended Loan and Security Agreement as of December 31, 2021 approximates its face value due to proximity to the transaction.
