No prepayments were made during the Make-Whole Period which expired on March 28, 2018. After the one year Make- Whole Period the Note may be prepaid in part or in full with no penalty. The Purchase Agreement contains representations and affirmative, negative and financial covenants usual and customary for financing of this type, including covenants that place conditions upon the Company’s ability to merge or consolidate with other companies, sell any material part of their business or property, incur liens, and pay dividends on, make distributions on or redeem their equity interests.

On November 13, 2017, the Company entered into an agreement modifying the terms of its Senior Secured Term Note. The modification included revisions to the original revenue and EBITDA covenants along with the requirement of minimum principal reductions of $30,000 per month beginning in April 2018. In consideration for the modified terms, the Company issued 500,000 warrants to purchase the Company’s common stock at an exercise price of $2.26 which expire in November 2023. The fair valve of the warrants of approximately $0.37 million was recognized as additional paid-in capital with a corresponding discount to long-term notes payable. The discount is accreted to interest expense through Note’s maturity. Discount accretion totaled $0.01 million and $0.03 for the three months and six months ended June 30 for both 2018 and 2017. As of June 30, 2018, the Company was not in compliance with certain financial covenants. However, as a condition to the Transaction referenced in Note 11, the Company subsequently paid off the debt in full with the Purchaser. On March 29, 2018, the Company’s subsidiary, M&I Brazil, extended the terms of its Loan Agreement with the former chairman of AETI to June 7, 2019. The Loan Agreement provides the Company with a $0.30 million loan facility of which $0.20 million is drawn and is outstanding as of June 30, 2018 and with any balance outstanding due June 7, 2019. Under the loan agreement, the interest rate on the loan facility is 10.0%, per annum, payable each quarter. The loan facility is secured by the assets held by M&I Brazil.
