Amerindo is registered as an investment advisor under the Investment Advisors Act of 1940, as amended. Messrs. Alberto W. Vilar and Gary A. Tanaka, whose business addresses are the same as those set forth for Amerindo and each of whom is a U.S. citizen, are the only directors and executive officers of Amerindo Panama. They are also the only directors and executive officers of Amerindo, other than Mr. James H. Furey, Chief Operating Officer, and Mr. Joaquin Garcia-Larrieu, Chief Financial Officer. Mr. Furey and Mr. Garcia's business addresses are at Amerindo's offices at 399 Park Avenue, New York, New York 10022. Messrs. Alberto W. Vilar, Gary A. Tanaka, James P.F.

Additionally, because each of the Advisor Entities is obligated to act in the best interests of its respective clients and in accordance with the respective mandates of those clients, there is no agreement between or among any of the Reporting Persons to act together with respect to the Issuer or its securities, except that they may, from time to time and provided that transactions are otherwise being effected at the same time, aggregate orders for client accounts in order to receive more favorable trading terms. Any of the subject securities acquired or which might in the future be acquired by any of the Named Individuals have been and would be acquired for investment and not with the purpose of effecting change or influencing the control of the issuer or in connection with or as a participant in any transaction having such purpose or effect, including any transaction subject to Rule 13D/A-3(b) under the Exchange Act.
