On July 31, 2014, Aston Capital, LLC (“Aston”) agreed to convert $5,688,654.37 of short-term loans and cash advances paid to Revolution Lighting Technologies, Inc. (“Revolution” or the “Company”) into a long-term note due April 1, 2016 (the “Exchange”).

In connection with the Exchange, the Company and Aston entered into and closed the transactions contemplated by the Exchange Agreement (the “Exchange Agreement”). Aston is an affiliate of Robert V.

Pursuant to the Exchange Agreement, the Company issued to Aston a promissory note, dated July 31, 2014, in the principal amount of $5,668,654.37 (the “July 2014 Note”) in exchange for (i) $1,000,000 of the entire outstanding principal amount of that certain promissory note, dated April 4, 2014, made by the Company in favor of Aston, with a maturity date of April 1, 2015 (the “April 2014 Note”); (ii) $1,968,654.38 of the entire outstanding principal amount of that certain promissory note, dated June 30, 2014, made by the Company in favor of Aston, with a maturity date of April 1, 2015 (the “June 2014 Note”); and (iii) $2,700,000 representing cash advances made by Aston from time to time during May and June 2014 which were ratified by the Audit Committee as part of the Exchange Agreement, including nine percent (9%) interest on such amount as approved by the Audit Committee (the “Cash Advances”). Pursuant to the Exchange Agreement, the accrued and unpaid interest as of July 31, 2014 on each of the April 2014 Note, the June 2014 Note and the Cash Advances was excluded from the Exchange. The July 2014 Note accrues interest at a rate of nine percent (9%) per annum. All principal and interest under the July 2014 Note is due and payable on April 1, 2016.

The Exchange Agreement and the July 2014 Note were approved by the Audit Committee of the Board.

There were no costs or consideration paid by the Company in connection with the Exchange. After closing the Exchange, the Company has no current debt outstanding, with the exception of approximately $1.1 million as of June 30, 2014 under an accounts receivable financing facility.
