This Assignment Agreement, dated as of April 22, 2011, (this “Agreement”), is by and between Lighting

WHEREAS, LSGC wishes to assign all of its rights, title and interests in the Proceeds to Holdings II in return for cash payments totaling
$6.5 million (such payments being collectively referred to as the “Price”) plus the Contingent Payment (as defined below) (the Contingent Payment and Price are collectively referred to herein as the “Cash
Consideration”). 
 NOW, THEREFORE, in consideration of the premises and the mutual agreements contained herein,
and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, LSGC and the Holdings II, intending to be legally bound, hereby agree as follows: 

1. Assignment. Subject to the conditions set forth in Section 4 of this Agreement:

b. Holdings II does hereby accept the Assignment; and 
 c. LSGC and Holdings II intend for this Assignment to not conflict with the Policy’s provisions regarding assignment. 
 2. Cash Consideration. In consideration for the Assignment, Holdings II shall pay to LSGC:

 d. Notwithstanding anything in this Section 2, under no circumstances shall the
Contingent Payment be less than zero or greater than $450,000. 
 3. Transfer of Ownership. In addition to the above Cash
Consideration, LSGC hereby agrees that, at the request of Holdings II, it shall take all actions necessary to transfer or assign ownership of the Policy in accordance with the Policy’s terms, along with any associated rights, including any and

 c. The authorization, execution, delivery and performance of this Agreement by LSGC will not result in any breach of

other document, instrument or agreement or any judgment, order or decree to which LSGC is a party except where any such breach or default would reasonably expected to, alone or in the aggregate, have a material adverse effect on the financial

 d. To the knowledge of LSGC: (i) the
Policy is a legal, valid and binding obligation of the Insurer, enforceable against the Insurer in accordance with its terms, and (ii) the Insurer has not indicated in any manner (oral, written or otherwise) that it does not intend pay the
proceeds in accordance with the Policy.
