On April 11, 2007, Nexxus Lighting, Inc. (the “Company”) amended its Certificate of Incorporation to (i) change its name from Super Vision International, Inc. to Nexxus Lighting, Inc., (ii) increase the number of authorized shares of the Company’s Common Stock, $.001 par value per share, from 20,000,000 shares to 25,000,000 shares, (iii) eliminate the Company’s Class B Common Stock and (iv) reclassify all of the Company’s Class A Common Stock, $.001 par value per share, as Common Stock, $.001 par value per share.
