We have acted as counsel in connection with the preparation and filing of that certain Registration Statement on Form S-8 (the “Registration Statement”) to be filed by you with the Securities and Exchange Commission under the Securities Act of 1933, as amended, in connection with the registration of 2,464,000 shares of Common Stock, $0.0001 par value per share (the “Common Stock”), of Learning Tree International, Inc., a Delaware corporation (the “Company”), issuable upon the exercise of options granted to certain employees and others of the Company pursuant to the Company’s Amended and Restated 1999 Stock Option Plan (the “Plan”). As such counsel, we have examined the proceedings taken in connection with the Plan and proposed to be taken in connection with the sale and issuance of the Common Stock pursuant thereto and such other matters and documents as we have deemed necessary or relevant as a basis for this opinion.
