On December 23, 2013, the Company entered into a Senior Convertible Promissory Note (the "Note") with Michaelson Capital Special Finance Fund LP, ("Michaelson"), for the principal amount of $3,000,000 with interest at 4% per annum for a term of three years. On April 1, 2016, the Company amended the Note increasing the total principal amount to $3,150,000 increasing the conversion price to $3.54 from $3.37, and extending the term until December 23, 2018. The amended Note was a senior secured obligation which paid interest only on a monthly basis in arrears at a rate of 4% per annum, unless earlier converted in accordance with the terms of the agreement prior to such date. The Note was secured by an all asset lien and was senior in right of payment to any unsecured indebtedness that is expressly subordinated in right of payment to the Note.
On December 14, 2017, the Company, through principal payment of $3,150,000 to Michaelson (the "Payment"), terminated the Senior Convertible Promissory Note with Michaelson. Through the Note, Michaelson was the Company's principle debt holder and a beneficial holder of approximately 5% of the Company's shares outstanding. There were no pre-payment penalties paid by the Company, as Michaelson provided a waiver of the pre-payment penalties that were contained in the Note. By completing the Payment, the Company has satisfied all of its obligations under the Note and the Note was cancelled. Below is a summary of the terms of the Note, as amended.
The Company could prepay all of the outstanding principal and interest due and payable under this Note in full, at any time prior to the maturity date for an amount equal to 120% of the then outstanding principal and interest due and payable as of the date of such prepayment.
In connection with the acquisition of American DG Energy, the Company assumed a loan from John N. Hatsopoulos, the Company's then Co-Chief Executive Officer and a Company Director. The loan was in the amount of $850,000 with interest at 6%, payable quarterly. On May 4, 2018, the Company, through a payment of $919,590, terminated the loan and all obligations under the loan.
On May 4, 2018 ("Closing Date") the Company, and its wholly owned subsidiaries, American DG Energy Inc. and TTcogen LLC (collectively, the "Borrowers"), entered into a Credit Agreement with Webster Business Credit Corporation (the "Lender") that matures in May 2021 and provides Borrowers a line of credit of up to $10 million on a revolving and secured basis, with availability based on certain accounts receivables, raw materials, and finished goods.
Borrowings under the Credit Agreement bear interest at a rate equal to, at the Borrower's option, either (1) One Month LIBOR, plus 3.00%, or (2) Lender’s Base Rate, plus 1.5%. Lender’s Base Rate is defined as the highest of (a) the Federal Funds rate plus 0.5%, (b) Lender’s Prime Rate as adjusted by Lender from time to time, and (c) One Month LIBOR, plus 2.75%, 7% as of December 31, 2018.
The Credit Agreement contains certain affirmative and negative covenants applicable to the Company and its subsidiaries, which include, among other things, restrictions on their ability to (i) incur additional indebtedness, (ii) make certain investments, (iii) acquire other entities, (iv) dispose of assets and (v) make certain payments including those related to dividends or repurchase of equity. The Credit Agreement also contains financial covenants including maintaining a fixed charge coverage ratio of not less than 1.10:1.00 and the Company may not make any unfinanced capital expenditures in excess of $500,000 in the aggregate in any fiscal year. As of December 31, 2018, the Company believes it is in compliance with covenants.
The $145,011 of costs incurred in connection with the issuance of the revolving credit facility were capitalized and are being amortized to interest expense on a straight-line basis over three years based on the contractual term of the Agreement. As of December 31, 2018, the outstanding balance on the line of credit was $2,122,221 and the unamortized portion of debt issuance cost related to the Credit Agreement was $112,786 and is included as a reduction to the revolving line of credit in the accompanying Consolidated Balance Sheet.
