Revolving Credit Facility

On September 30, 2014, the Company and its wholly-owned subsidiary, EthoStream, as co-borrowers (collectively, the “Borrowers”), entered into a loan and security agreement (the “Heritage Bank Loan Agreement”), with Heritage Bank of Commerce, a California state chartered bank (“Heritage Bank”), governing a new revolving credit facility in a principal amount not to exceed $2,000,000 (the “Credit Facility”). Availability of borrowings under the Credit Facility from time to time is subject to a borrowing base calculation based on the Company’s eligible accounts receivable and eligible inventory each multiplied by an applicable advance rate, with an overall limitation tied to the Company’s eligible accounts receivable. The Heritage Bank Loan Agreement is available for working capital and other general business purposes. The outstanding principal balance of the Credit Facility bears interest at the Prime Rate plus 3.00%, which was 7.00% at March 31, 2017 and 6.75% at December 31, 2016. On October 9, 2014, as part of the Heritage Bank Loan Agreement, Heritage Bank was granted a warrant to purchase 250,000 shares of Telkonet common stock. The warrant has an exercise price of $0.20 and expires October 9, 2021. On February 17, 2016, an amendment to the Credit Facility was executed extending the maturity date to September 30, 2018, unless earlier accelerated under the terms of the Heritage Bank Loan Agreement.

The Heritage Bank Loan Agreement also contains financial covenants that place restrictions on, among other things, the incurrence of debt, granting of liens and sale of assets. The Heritage Bank Loan Agreement also contains financial covenants that require the Borrowers to maintain a minimum EBITDA level, measured quarterly, and a minimum asset coverage ratio, measured monthly. A violation of any of these covenants could result in an event of default under the Heritage Bank Loan Agreement. Upon the occurrence of such an event of default or certain other customary events of defaults, payment of any outstanding amounts under the Credit Facility may be accelerated and Heritage Bank’s commitment to extend credit under the Heritage Bank Loan Agreement may be terminated. The Heritage Bank Loan Agreement contains other representations and warranties, covenants, and other provisions customary to transactions of this nature. As of March 31, 2017, the Company was in compliance with all financial covenants. The outstanding balance on the Credit Facility was zero and $1,062,129 at March 31, 2017 and December 31, 2016, respectively. The remaining available borrowing capacity was approximately $1,071,000 and $107,000 at March 31, 2017 and December 31, 2016, respectively.

On March 28, 2017, the Company and the Company’s wholly-owned subsidiary, EthoStream, entered into an Asset Purchase Agreement with DCI-Design Communications LLC (“DCI”), whereby DCI would acquire all of the assets and certain liabilities of EthoStream. Heritage Bank had provided the Company with its consent to the sale transaction. Upon closing of the sale transaction on March 29, 2017, the entire balance outstanding on the Credit Facility was repaid. On March 29, 2017 an amendment to the Credit Facility was executed amending the quarterly and year to date EBITDA compliance measurements for 2017.
