As previously disclosed in the Company’s Current Report on Form 8-K filed on April 13, 2015, the Company received notice stating that the Company had failed to maintain compliance with covenants thereby creating an event of default under the Loan Agreement and under the Financing Agreement and declaring all obligations of GridSense owing under the Loan Agreement and the Financing Agreement to be immediately due and payable. As of the date of the Notice, GridSense owed approximately $1,480,000 and $158,000 under the Loan Agreement and the Financing Agreement, respectively.

Effective as of April 30, 2015, GridSense and the Bank entered into an amendment to the Loan Agreement (the “Amendment”) pursuant to which (i) the Bank waived events of default under the Loan Agreement and a related accounts receivable financing agreement, (ii) GridSense paid $500,000 to the Bank in reduction of its obligations under the Loan Agreement, (iii) the Company deposited $250,000 on May 4, 2015 into a restricted account (the “Restricted Account”) at the Bank to secure the Company’s guaranty of GridSense’s obligations under the Loan Agreement and agreed to make additional deposits into the Restricted Account of $250,000 by May 14, 2015 and $250,000 by July 31, 2015, (iv) GridSense agreed to the repayment, commencing September 1, 2015, of an aggregate of $250,000 of advances under the Loan Agreement in equal monthly installments through May 1, 2016, and (v) the Company is required to have an unrestricted cash balance equal to no less than the amount of all obligations of GridSense to the Bank which are not secured by the Restricted Account.
