Pursuant to the Securities Purchase Agreement, the Company acquired 100% of the issued and outstanding stock of Velvec from the Sellers (the “Acquisition”) for $39.5 million and an earnout consideration contingent upon Velvac achieving minimum earnings performance levels and based on sales of Velvac’s new proprietary Road-iQ product line (the “Earnout Consideration”). Velvac is a premier designer and manufacturer of proprietary vision technology for original equipment manufacturers serving the heavy-duty and medium-duty truck, motorhome, and bus markets. Approximately two-thirds of Velvac’s sales are represented by proprietary mirrors and camera-enabled vision systems that provide substantial value to their customers. The remaining one-third of sales are represented by aftermarket components. Velvac recorded net sales of approximately $60 million for Fiscal year 2016. Velvac maintains manufacturing operations in Reynoso, Mexico and has distribution facilities at its headquarters in New Berlin, Wisconsin; in El Paso, Texas; Anaheim, California; and in Toronto, Ontario, Canada.

On April 3, 2017, the Company signed an amended and restated loan agreement (the “Loan Agreement”) with People’s United Bank that included a $31 million term portion and a $10 million revolving credit portion. Proceeds of the loan were used to repay the remaining outstanding term loan of the Company (approximately $1,429,000) and to acquire 100% of the common stock of Velvac Holdings, Inc. The term portion of the loan requires quarterly principal payments of $387,500 for a two-year period beginning July 3, 2017. The repayment amount then increases to $775,000 per quarter beginning July 1, 2019. The term loan is a five-year loan with the remaining balance due on March 1, 2022. The revolving credit portion has a quarterly commitment fee ranging from 0.2% to 0.375% based on operating results. Under the terms of the Agreement, this rate will be 0.25% for the first six months. The revolving credit portion has a maturity date of April 1, 2022. On April 3, 2017, the Company borrowed approximately $6.6 million on the revolving credit facility. On April 4, 2017, the Company entered into an interest rate swap contract with the lender with an original notational amount of $15,500,000, which is equal to 50% of the outstanding balance of the term loan on that date. The notational amount will decrease on a quarterly basis beginning July 3, 2017 following the principal repayment schedule of the term loan. The Company has a fixed interest rate of 1.92% on the swap contract and will pay the difference between the fixed rate and LIBOR when LIBOR is below 1.92% and will receive interest when the LIBOR rate exceeds 1.92%.
