under our at-the market equity offering program, and $0.1 million of proceeds received related to exercise of stock options and employee stock purchase plan.

On March 25, 2022 (the “Closing Date”) we entered into a loan and security agreement (the “Loan Agreement”), with Oxford as collateral agent and a lender, and Oxford Finance Credit Fund III LP, as a lender (“OFCF III” and together with Oxford, the “Lenders”) pursuant to which the Lenders have agreed to lend us up to an aggregate principal amount of $150.0 million in a series of term loans (the “Term Loans”). The initial Term Loan of $25.0 million was funded at the Closing Date of the Loan Agreement, an additional $75.0 million will be available at our option upon achievement of certain milestones as outlined in Note 7. Debt to our unaudited condensed consolidated financial statements included in this quarterly report, and $50.0 million is subject to the Lenders’ sole discretion.
The Term Loans bear interest at a floating rate equal to (a) the greater of (i) the one-month CME Secured Overnight Financing Rate and (ii) 0.13% plus (b) 7.37%, which is subject to an overall floor and cap. Interest is payable monthly in arrears on the first calendar day of each calendar month. Beginning (i) April 1, 2024, if the Term B Loan (as defined in Note 7. Debt to our unaudited condensed consolidated financial statements included in this quarterly report) is not made, (ii) April 1, 2025, if the Term B Loan is made, or (iii) April 1, 2026, if the Term B Loan is made and either (A) VS-6766 has received FDA approval for the treatment of LGSOC or (B) COPIKTRA has received FDA approval for the treatment of peripheral T-cell lymphoma (“PTCL”), we shall repay the Term Loans in consecutive equal monthly payments of principal, together with applicable interest, in arrears. All unpaid principal and accrued and unpaid interest with respect to each Term Loan is due and payable in full on March 1, 2027.
We are required to make a final payment of 5.0% of the original principal amount of the Term Loans that were drawn, payable at maturity or upon any earlier acceleration or prepayment of the Term Loans. We may prepay all, but not less than all, of the Term Loans, subject to a prepayment fee equal to (i) 3.0% of the principal amount of the applicable Term Loan if prepaid on or before the first anniversary date of the funding date of such Term Loan, (ii) 2.0% of the principal amount of the applicable Term Loan if prepaid after the first anniversary and on or before the second anniversary of the funding date of such Term Loan, and (iii) 1.0% of the principal amount of the applicable Term Loan if prepaid after the second anniversary of the applicable funding date of such Term Loan. All Term Loans are subject to a facility fee of 0.5% of the principal amount.
The Loan Agreement contains no financial covenants. The Loan Agreement includes customary events of default, including, among others, payment defaults, breach of representations and warrants, covenant defaults, judgment defaults, insolvency and bankruptcy defaults, and a material adverse change. The occurrence of an event of default could result in the acceleration of the obligations under the Loan Agreement, termination of the Term Loan commitments and the right to foreclose on the collateral securing the obligations. During the existence of an event of default, the Term Loans will accrue interest at a rate per annum equal to 5.0% above the otherwise applicable interest rate.
In connection with the Loan Agreement, we granted Oxford a security interest in all of our personal property now owned or hereafter acquired, excluding intellectual property (but including the right to payments and proceeds of intellectual property), and a negative pledge on intellectual property.
In August 2021, we entered into a sales agreement with Cantor Fitzgerald & Co. (“Cantor”) pursuant to which we can offer and sell up to $100.0 million of our common stock at the current market prices from time to time through Cantor as sales agent (“August 2021 ATM”). During the 2022 Period, we sold 285,900 shares under the August 2021 ATM for net proceeds of approximately $0.6 million (after deducting commissions and other offering expenses). As of March 31, 2022, we can issue an aggregate amount of $92.4 million of common stock under this program.

The 2018 Notes are governed by the terms of a base indenture for senior debt securities (the “Base Indenture”), as supplemented by the first supplemental indenture thereto (the “2018 Notes Supplemental Indenture” and together with the Base Indenture, the “2018 Indenture”), each dated October 17, 2018, by and between us and
