This press release is being issued pursuant to and in accordance with Rule 135c under the Securities Act.

Statements contained in this press release may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995.

These factors include, without limitation, Terremark’s ability to obtain funding for its business plans, uncertainty in the demand for Terremark’s services or products, Terremark’s ability to manage its growth, and the successful integration of operations of acquired companies.
