He and his family also own several small companies engaged in servicing the interior designer market, including International Arts Group, Lighting Effects, Wingz Marketing, Trimarc Logistics, and iDesign.

Subject to the approval of the Board, as compensation for serving as a non-employee director in 2010, Mr. Darnell is entitled to a prorated portion of the standard compensation provided to the Company’s non-employee directors: (i) $40,000 paid in equal quarterly installments within 30 days of the end of each calendar quarter; (ii) 3,000 options to purchase common stock of the Company at an exercise price equal to the fair market value of the Company’s common stock on the day of issuance, issued in equal quarterly installments within 30 days of the end of each calendar quarter, subject to the Company’s Amended and Restated Equity-Based Compensation Plan and execution of the Company’s non-qualified stock option agreement; (iii) $80,000 in restricted common stock of the Company; and (iv) compensation through the Company’s “Rainmaker” program to the extent that he facilitates sales of the Company’s products to certain identified customers.
