On February 21, 2013, Revolution Lighting Technologies, Inc. (“Revolution” or the “Company”), entered into an Investment Agreement (the “Investment Agreement”) with RVL 1 LLC (the “Investor”), an affiliate of Aston Capital, LLC, and closed the transactions contemplated by the Investment Agreement (the “Investment Closing”). The Company issued to the Investor 5,000 shares of the Company’s newly-created Series E Convertible Redeemable Preferred Stock, $0.001 par value per share (the “Series E Stock”) in consideration of a cash payment of $5 million (the “Investment”). The proceeds from the Investment are to be used for working capital purposes and to pay fees and expenses in connection with the Investment Agreement.

The Series E Stock initially shall be non-voting and non-convertible. The Series E Stock will become voting and convertible into shares of the Company’s common stock, $0.001 par value per share (the “Common Stock”) after the Company has complied with the requirements of Rule 14c-2 of the Securities Exchange Act of 1934, as amended, with respect to the written consent of the majority stockholder of the Company, dated as of February 21, 2013, approving the issuance of Common Stock upon conversion of the Series E Stock pursuant to Nasdaq Listing Rule 5635 (the “Trigger Date”). At any time from and after the Trigger Date, the Series E Stock will be convertible into Common Stock at a conversion price per share equal to $1.17, subject to certain anti-dilution adjustments (the “Conversion Price”).

From and after the Trigger Date, the Series E Certificate of Designations (as defined below) will provide the Investor with the same Board representation and consent rights as the existing series of preferred stock currently held by the Investor.

The Series E Stock will have a liquidation preference (the “Liquidation Preference”) per share equal to the greater of (i) $1,000 (subject to customary adjustments with respect to events affecting the Series E Stock) plus accrued but unpaid dividends and (ii) such amount as would have been received had the Series E Stock converted into Common Stock immediately prior to the liquidation.

The Company has the option to redeem all or any part of the Series E Stock for cash at any time subject to the Investor’s right to convert and require delivery of shares of Common Stock. The redemption price to be paid by the Company is equal to 110% of the

Liquidation Preference if the Series E Stock is redeemed on or before the first anniversary of the date of the original issuance of shares of Series E Stock (the “Original Issue Date”), 105% of the Liquidation Preference if the Series E Stock is redeemed after the first anniversary of the Original Issue Date but on or prior to the second anniversary of the Original Issue Date, and the Liquidation Preference if the Series E Stock is redeemed at any time thereafter.

At the option of the holders of two-thirds (2/3^rds) of the then-outstanding shares of Series E Stock, the Company must redeem the number of shares of Series E Stock so requested for cash at the Liquidation Preference. Such option can only be exercised on or after the third (3^rd) anniversary of the Original Issue Date.

Each share of Series E Stock shall be entitled to receive dividends (the “Series E Dividend”) payable at a rate per annum of five percent (5%) of the Series E Stated Value then in effect (the “Dividend Rate”). To the extent funds are legally available and the Company is not contractually prohibited from paying such Series E Dividend, the Series E Dividend must be declared and paid from and including the Original Issue Date on each six-month anniversary of the Original Issue Date. At the holder’s option, such dividends are payable through the issuance of additional shares of Series E Stock or in cash. To the extent the Company is unable to pay any Series E Dividend (i.e. in the event funds are not legally available or the Company is contractually prohibited from making payment), any such unpaid Series E Dividend shall be cumulative and shall accrue and compound on a quarterly basis at the then applicable Dividend Rate. Such unpaid Series E Dividend shall be paid as soon as funds are legally available or as soon as the Company is no longer contractually prohibited from paying such Series E Dividend, as applicable. Additionally, the Series E Stock shall share ratably on an as-converted basis with the Common Stock in the payment of all other dividends and distributions.

In connection with the Investment, the Company entered into a Registration Rights Agreement Acknowledgement pursuant to which the Company acknowledged that the Registration Rights Agreement, disclosed in the Company’s Current Report on Form 8-K filed with the SEC on September 26, 2012, which is applicable to shares of Common Stock issuable upon conversion of the existing Series B Convertible Preferred Stock and existing Series C Senior Convertible Preferred Stock, is also applicable to the shares of Common Stock issuable upon conversion of the Series E Stock.

The Investment Agreement was unanimously approved by the Audit Committee of the Board of Directors of the Company.

The foregoing is a summary of the material terms of the Investment Agreement and the Series E Stock. Investors are encouraged to review the entire text of the Investment Agreement and the Series E Certificate of Designations, copies of which are filed as Exhibit 10.1 and Exhibit 3.1 to this Report, respectively, and incorporated herein by reference.
