CALCULATION OF FILING FEE

Transaction Valuation*	Amount of Filing Fee**
$3,685,933,290.20	$428,306

*

Estimated for purposes of calculating the filing fee only. The transaction valuation was calculated by adding the sum of (i) 140,847,744 shares of common stock, par value $0.01 per share (the "Shares"), of Sapient Corporation ("Sapient") outstanding multiplied by the offer price of $25.00 per share, (ii) 6,543,218 Shares subject to outstanding unvested restricted stock units and performance restricted stock units (assuming achievement of any performance conditions applicable to the performance restricted stock units at the maximum level), which reflects the maximum number of restricted stock units and performance restricted stock units that may be outstanding at the time the offer is completed, multiplied by the offer price of $25.00 per share and (iii) 66,623 Shares issuable pursuant to outstanding options multiplied by the offer price of $25 per share less the weighted average exercise price for such options of $7.60 per share. The calculation of the filing fee is based on information provided by Sapient as of November 7, 2014.

**

The filing fee was calculated in accordance with Rule 0-11 under the Securities Exchange Act of 1934, as amended, and Fee Rate Advisory No. 1 for Fiscal Year 2015, issued August 29, 2014, by multiplying the Transaction Valuation by 0.0001162.
