On March 23, 2017, the Company and its subsidiaries, M&I Electric Industries, Inc. and South Coast Electric Systems, LLC (collectively, the “Sellers”) issued and sold to HD Special-Situations III, L.P. (the “Purchaser”) a $7.00 million principal amount Senior Secured Term Note (the “Note”) with principal of $0.50 million due and paid on June 30, 2017 with the balance due 48 months after issuance for cash at par pursuant to a Note Purchase Agreement (the “Purchase Agreement”). Proceeds from the sale of the Note were used to fully repay and terminate the Company’s prior revolving credit facilities with approximately $1.00 million being available for the Company’s working capital and general business purposes. The Note bears interest at 11.5% per annum payable monthly in arrears. The Note is secured by a first-priority lien on substantially all existing and after-acquired personal property assets and real estate owned by the Sellers (with certain exceptions). The Note is subject to an interest “make-whole” provision such that any prepayment of the principal thereunder in excess of $1.50 million (the “Prepayment Threshold”) within one year of the date of issuance (the “Make-Whole Period”) shall be subject to the payment of a prepayment premium, on the date of such prepayment, in an amount based on an interest rate of 11.5% per annum of the prepayment amount in excess of the Prepayment Threshold for the portion of the Make-Whole Period that will remain after the date that the prepayment is made. 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. Other covenants in the Purchase Agreement require the Company to maintain minimum monthly revenue, maintain minimum monthly EBITDA, maintain minimum monthly cash on hand, maintain a minimum monthly debt service coverage ratio, maintain a maximum debt-to-EBITDA ratio, maintain a minimum monthly collateral coverage ratio and obtain consent of the Purchaser for certain capital expenditure. In the event that the Company fails to meet covenants in the future, the Company may not be able to obtain the necessary waivers or amendments to remain in compliance with the Purchase Agreement and the Purchaser may declare a default and cause all of the Company’s outstanding indebtedness under the Purchase Agreement to become immediately due and payable or otherwise subject to an additional rate of 4.0% per annum and scheduled amortization of principal. On November 13, 2017, the Company entered into an agreement modifying the terms of its Senior Secured Term Note. The modification included a waiver of an EBITDA covenant violation as of September 30, 2017 and 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 2022.

The fair value assigned to the warrants of approximately $0.37 million was recognized as an increase in additional paid-in-capital with a corresponding discount on the notes payable. The discount is accreted through interest expense over the remaining term of the note payable.The fair value of the warrants was calculated using the Black Scholes-Merton pricing model using the following weighted average assumptions, at the grant date:

Number of warrants		500,000
Exercise price	$	2.26
Expected volatility of underlying stock		72	%
Risk-free interest rate		2.08	%
Dividend yield		0	%
Expected life of warrants		5 years
Weighted-average fair value of warrants	$	0.73
Expiration date		November 13, 2022
