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 6.50% at September 30, 2016 and December 31, 2015. 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 June 30, 2016, the Company was in violation of a financial performance covenant. Heritage Bank granted a waiver of that violation on August 11, 2016. By waiving the violation, Heritage Bank is not surrendering any of its other rights set forth in the Heritage Bank Loan Agreement. On October 27, 2016, an amendment to the Credit Facility was executed modifying the required minimum EBITDA level financial covenant as of September 30, 2016 and December 31, 2016. As of September 30, 2016, the Company was in compliance with the modified financial covenants. The outstanding balance on the Credit Facility was $1,011,771 and $901,771 at September 30, 2016 and December 31, 2015, respectively, leaving an available borrowing base of approximately $217,000 and $532,700 at September 30, 2016 and December 31, 2015, respectively.
