SECTION 5. CORPORATE GOVERNANCE AND MANAGEMENT Item 5.02. Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers. On October 4, 2010, the Company appointed James B. Nelson as a director, President and Chief Executive Officer of Solar3D, Inc., a Delaware corporation (the "Company" or "Solar3D"). Mr. James Nelson began his executive career 30 years ago at Bain and Company, a business strategy consulting firm, where he managed a team of consultants on four continents solving CEO-level programs for global companies. Prior to joining the Company, he spent 20 years working in the private equity industry as both a capital partner and operating CEO to portfolio companies. Mr. Nelson was a General Partner at Peterson Partners (2007-2009) and at Millennial Capital Partners (1991-2010--previously known as Invest West Capital). In addition to his responsibilities in acquisition and divestiture, Mr. Nelson worked as an executive of a number of portfolio companies. He served as CEO of Euro-Tek Store Fixture, LLC, Chairman of the Board of American Retail Interiors, Chairman of the Board and CEO of Panelview Inc. and Chairman of the Board of Critical Power Exchange, as well as sitting on numerous Boards both in and out of the private equity funds' portfolios. Prior to his years in private equity, Mr. Nelson served as Vice President of Marketing at Banana Republic/The Gap, where he managed company-wide marketing, as well as the initial international expansion of Banana Republic. He was also General Manager for Banana Republic's highly profitable catalog division. He also served as Vice President of Marketing and Corporate Development at Saga Corporation, a multi-billion dollar food service company. Mr. Nelson received his MBA from Brigham Young University, where he graduated Summa Cum Laude and was named the Outstanding Master of Business Administration Graduate. We believe that Mr. Nelson's experience in global companies, worldview strategic thinking, and hands-on entrepreneurial and operating execution is ideally suited to help exploit Solar3D's solar cell technology in a global market opportunity. In consideration for his services as a director of the Company, the Company issued to Mr. Nelson a nonqualified stock option to purchase up to 15,000,000 shares of the Company's common stock for a period of seven years from the date of grant (i.e., July 22, 2010), at a purchase price of $0.05 per share (after taking into account the one-for-five reverse stock split recently effected by the Company), as previously described in the Company's Report on Form 8-K, dated August 5, 2010. The stock options were granted on July 22, 2010 and vest 1/36th per month commencing on August 21, 2010, on a monthly basis for as long as Mr. Nelson is an employee or consultant of the Company. In consideration for Mr. Nelson's services as the President and Chief Executive Officer of the Company, the Company has agreed to pay to Mr. Nelson an annual salary of $200,000, commencing to accrue on October 1, 2010, payable in two equal installments each month during the year. On October 4, 2010, Roland F. Bryan resigned as the Chief Executive Officer and President of the Company in order to allow James B. Nelson to be appointed for those positions. Mr. Bryan will remain as the Company's Chief Financial Officer and corporate Secretary. -1-
