On November 7, 2017, Psychemedics Corporation (the “Company”) amended its equipment financing arrangement with Banc of America Leasing & Capital, LLC (the “Lender”), including its Master Loan and Security Agreement and related documentation (collectively the “Equipment Loan Arrangement”) pursuant to which the amount Company has the ability to finance, at its option, was increased by $4.0 Million of new and used equipment purchases, and the term of the loan facility was extended until November 1, 2018. Each such purchase that is financed under the Equipment Loan Arrangement is documented by the execution of an equipment note (each an “Equipment Note”). Each Equipment Note has a maturity date of 60 months from the applicable loan date, and shall bear interest at the then current 30-day LIBOR rate + 1.75% (which would amount to an annual rate of 2.99% as of the date of filing of this report), or at such rate as the parties may otherwise mutually agree. Principal and interest are payable over the 60-month repayment period and principal can be repaid without premium or penalty under any Equipment Note unless it is a fixed rate loan. Borrowings under the Equipment Loan Arrangement, as amended, are secured by a first priority security interest in the equipment to be acquired with the proceeds of the Equipment Notes. Under the Equipment Loan Arrangement, the Company is subject to a maximum quarterly funded debt to EBITDA ratio and a minimum fixed charge coverage ratio. On November 10, 2017, the Company executed an Equipment Note in the principal amount of $2,078,470.86. The due date under the Equipment Note is November 10, 2022. A description of the original Equipment Loan Arrangement is provided under the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on March 26, 2014, and a copy of the documentation evidencing the Equipment Loan Arrangement was included as Exhibits 10.2 and 10.3 to the Company’s Quarterly Report on Form 10-Q for the First Quarter of 2014 filed on May 1, 2014.
