Satellite Beach, Florida, January 3, 2011 - Lighting Science Group Corporation (OTCBB: LSCG) is saddened to announce the passing of Zachary S. Gibler, the Company’s Chairman and Chief Executive Officer, following serious injuries sustained from a fall while riding his bicycle on January 2nd. Lighting Science Group mourns his loss and celebrates his extraordinary legacy. Mr. Gibler was the guiding force in building one of America’s leading and transformative LED lighting companies, Lighting Science Group. Mr. Gibler’s efforts helped to revolutionize the LED lighting world, and he was instrumental in building the Company’s outstanding, talented and experienced management team. Most importantly, however, Mr. Gibler was a loving husband, father and friend.

Richard Weinberg, a member of the Company’s board of directors and a Co-Managing Director at Pegasus Capital Advisors, L.P., will assume the duties of Chairman of the board of directors and have direct day-to-day involvement in the Company. Mr. Weinberg has been instrumental in directing the management of Lighting Science Group since Pegasus Capital assumed majority control of the Company in 2007. In addition, Donald Harkleroad, President of The Bristol Company, and Charles Darnell, former Vice Chairman of Acuity Brands, have become Vice Chairmen of the board of directors. Both Harkleroad and Darnell bring strong backgrounds in lighting and manufacturing and will assume active roles in management oversight. Weinberg, Harkleroad and Darnell will comprise a new “Office of the Chairman” that will assume CEO responsibilities on an interim basis. Additionally, the Company’s senior management team will continue to serve in its current capacity to drive manufacturing, sales, technological innovation and marketing. Under the day-to-day direction of the Office of the Chairman, this team will continue to propel the organization forward.

“Zach was a truly unique person who helped build an extraordinary company. He will be greatly missed by all who knew him,” said Richard Weinberg. “One of his greatest strengths was his aptitude for building a deep and effective management team, one of the best in the lighting industry. I am confident that Lighting Science Group’s strong growth and industry-leading performance will continue as a result of Zach’s dedication to the Company’s success. I firmly believe in our team and know they will continue to build upon Zach’s legacy.”

“Personally, Zach was much more than just a great executive. He was my friend. His drive, passion and dedication motivated me and all who knew him. Notwithstanding Zach’s business accomplishments, his dedication to family, always putting them first, was Zach’s most impressive characteristic. He treated his Lighting Science Group family the same way. I know that Zach took great pride in the fact that he helped to create hundreds of jobs and to make Lighting Science Group the largest employer in Satellite Beach, Florida,” added Weinberg.
