LEARNING TREE TO EXPLORE POSSIBLE SALE OF THE COMPANY

RESTON, VA — May 28, 2008—Learning Tree International, Inc. (NASDAQ: LTRE) today announced that a special committee of its independent directors has decided to solicit offers to purchase the company.

“For over 33 years, Learning Tree has taken the lead in providing the highest quality, vendor-independent education and training for managers and IT professionals worldwide,” commented Learning Tree President and CEO Nicholas R. Schacht. “In the past year we achieved significant improvements in profitability and revenue, further enhancing our already strong financial position. We believe this is an appropriate time to solicit offers to determine if a sale is the best way to maximize shareholder value. A sale would also address the desires of our two founders, who remain our principal shareholders, for diversification and liquidity to accommodate their charitable interests.”

“As we proceed with this process, we will continue to provide our customers with the same high levels of service and results for which we are known,” Schacht concluded.

Learning Tree has retained RBC Capital Markets, a subsidiary of the Royal Bank of Canada, as its financial advisor and Manatt, Phelps & Phillips, LLP as its legal advisor. Learning Tree has not ruled out either continuing as a stand-alone company or pursuing some other strategic alternative. Learning Tree does not plan to release additional information about the status of this process until a definitive agreement is executed or Learning Tree otherwise determines that further disclosure is appropriate.
