On September 7, 2006, UTEK renewed the Strategic Alliance Agreement with World Energy Solutions, pursuant to which UTEK agreed to perform certain services for World Energy Solutions during the subsequent 12-month period beginning September 9, 2006, relating to the identification and acquisition of new technology, in consideration of a payment of 82,759 shares of the common stock of World Energy Solutions.

On September 11, 2006, UTEK entered into an IP Snapshot Agreement with World Energy Solutions, pursuant to which UTEK agreed to perform certain services for World Energy Solutions and provide World Energy Solutions a report as to their findings in consideration of a payment of 87,500 shares of the common stock of World Energy Solutions. The 87,500 shares from the agreement were earned upon issuance of the report in September 2006.

On October 9, 2006, UTEK received 100,000 shares of Series A convertible preferred stock of World Energy Solutions in connection with the sale of its wholly-owned subsidiary, Pure Air Technologies, Inc. (“PATI”), to World Energy Solutions. At the time of the sale, PATI held $300,000 in cash; a technology licensed from the University of Florida Research Foundation and prepaid research funds related to the Arizona State University.

UTEK intends to sell the shares of common stock it presently holds, and those into which it converts the preferred stock of World Energy Solutions in the future, as permitted under SEC Rule 144 and as market conditions permit.

As of August 9, 2007, UTEK was the record owner of 201,672 shares of common stock of World Energy Solutions, Inc. and was the record owner of 100,000 shares of Series A convertible preferred stock of World Energy Solutions, Inc. that would be convertible after October 9, 2007 into approximately 6,750,000 shares of World Energy Solutions, Inc. common stock, assuming that the average of the closing prices for the World Energy Solutions, Inc. common stock for the 10 trading days prior to the conversion of the stock was $.60 per share, which was the market price of the common stock on August 9, 2007.

All of such shares of common stock (6,951,672 shares) would constitute approximately 21.6% of the 32,176,184 shares of common stock that would be outstanding after the conversion of such convertible preferred stock (based on the number of shares outstanding as contained in the most recently available filings with the Commission by World Energy Solutions, Inc.). UTEK has the sole power to vote and dispose of all of such shares.

The 82,759 shares of World Energy Solutions common stock issued to UTEK upon the renewal of their Strategic Alliance Agreement on September 9, 2006, are earned ratably over the 12-month period of the Agreement. If the Agreement is terminated prior to the end of such period, UTEK is obligated to return the unearned shares.

Except as described above, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any securities of World Energy Solutions, including but not limited to transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
