CALCULATION OF FILING FEE

Transaction Valuation(1)	Amount of Filing Fee(2)
$1,514,272,412.00	$175,807.03

(1) Estimated for purposes of calculating the filing fee only. The transaction valuation was calculated by adding (i) 67,402,815 shares of common stock of Terremark Worldwide, Inc. (“Terremark”) outstanding multiplied by the offer price of $19.00 per share, (ii) 2,030,268 shares of common stock of Terremark, which were subject to issuance pursuant to the exercise of outstanding options multiplied by $19.00, (iii) 3,168,437 unvested shares of restricted common stock of Terremark multiplied by $19.00, (iv) 2,014,750 shares of common stock of Terremark, which were subject to issuance pursuant to the exercise of outstanding warrants multiplied by $19.00 and (v) 5,082,278 shares of common stock of Terremark reserved for issuance upon the conversion of the 6.625% senior convertible notes of Terremark due 2013, which is the number of shares of common stock that may be issued under the convertible notes assuming an offer price of $19.00 per share and a closing date of March 11, 2011. Other than with respect to the number of shares of common stock of Terremark reserved for issuance upon the conversion of the 6.625% senior convertible notes of Terremark due 2013, the calculation of the filing fee is based on Terremark’s representation of its capitalization as of January 26, 2011.

(2) The filing fee was calculated in accordance with Rule 0-11 under the Securities Exchange Act of 1934 by multiplying the transaction value by 0.00011610.
