1. This Addendum modifies and supplements the LOC Note referenced above, and is hereby incorporated into the LOC Note as an integral part thereof.

Additionally, it is hereby agreed that the Commitment Letter between the same parties dated May 29, 2013 survives the making of the LOC Note and this Agreement, and shall continue to bind the parties for so long as the Revolving Line remains open or any indebtedness remains thereunder.

b. sell, convey, lease or transfer any of its assets other than in the ordinary course of business, or merge or consolidate with or into any other company or corporation; or
