Explanation of Responses:

( 1 )Pursuant to the terms of the Series G Unit Subscription Agreement (the "Series G Subscription Agreement") dated December 1, 2011, by and among Lighting Science Group Corporation (the "Issuer"), PCA LSG Holdings, LLC ("PCA Holdings"), Pegasus Partners IV, L.P. ("Pegasus Partners"), Ensemble Lights, LLC, Mark Kristoff, Alan Docter, Belfer Investment Partners L.P., Lime Partners, LLC and LSGC Holdings II LLC ("Holdings II"), on January 17, 2012, Pegasus Partners assigned a portion of its option (the "Option") to purchase the Issuer's Series G Units ("Series G Units") under the Series G Subscription Agreement to Continental Casualty Company ("CCC") and CCC executed a joinder to the Series G Subscription Agreement and partially exercised the Option by electing to purchase 5,000 Series G Units (the "Series G Unit Investment"). (Continued in footnote 2) ( 2 )(Continued from footnote 1) As a result of the assignment of the Option by Pegasus Partners and the purchase of Series G Units by CCC, the Option held by Pegasus Partners, PCA Holdings and Holdings II was reduced to an option to purchase 892 Series G Units. Each Series G Unit consists of: (a) one share of the Issuer's Series G Preferred Stock (the "Series G Preferred Stock") and (b) 83 shares of the Issuer's common stock. (Continued in footnote 3) ( 3 )(Continued from footnote 2) In consideration for the Series G Unit Investment and certain other mutual promises contained in a Letter Agreement dated January 17, 2012 ("the "Letter Agreement"), between CCC and LSGC Holdings LLC ("Holdings"), Holdings in the Letter Agreement agreed to amend the terms of the Class C Preferred Interests (the "Class C Preferred Interests") of Holdings issued by Holdings to CCC pursuant to the Binding Term Sheet dated May 13, 2011 (the "Binding Term Sheet") such that the dividend rate on the Class C Preferred Interests and the number of shares of the Issuer's common stock associated therewith are substantially the same as those of the Series G Preferred Stock. (Continued in footnote 4) ( 4 )(Continued from footnote 3) In order to make the number of shares of the Issuer's common stock associated with the Class C Preferred Interests substantially the same as the number of shares of the Issuer's common stock associated with the Series G Preferred Stock, Holdings agreed to accelerate the transfer to CCC of 281,250 shares of the Issuer's common stock due to CCC on May 26, 2012, and 281,250 shares of the Issuer's common stock due to CCC on May 26, 2013, and to transfer an additional 120,000 shares of the Issuer's common stock to CCC. (Continued in footnote 5) ( 5 )(Continued from footnote 4) In addition, pursuant to the Letter Agreement, if at any time on or prior to November 17, 2013, CCC exercises its rights pursuant to Section 8 of the Series G Subscription Agreement to convert all of its Series G Units into newly issued securities of the Issuer or if any amendments are made to the dividend rate of the Issuer's Series G Preferred Stock or the number of shares of the Issuer's common stock associated therewith (the "MFN Securities"), then Holdings shall amend the terms of the Class C Preferred Interests such that the dividend rate on the Class C Preferred Interests and the number of shares of common stock associated therewith are substantially the same as the MFN Securities. (Continued in footnote 6) ( 6 )(Continued from footnote 5) If upon the conversion of the Series G Units to MFN Securities, CCC is required to return to the Issuer some or all of the Issuer's common stock acquired as part of the purchase of Series G Units, then CCC will return to Holdings that same proportion of shares of the Issuer's common stock as part of the amendment to the terms of the Class C Preferred Interests.
