CALCULATION OF FILING FEE

Transaction Valuation	Amount of Filing Fee
$6,928,074,643.15	$862,545.29

(1) Estimated for purposes of calculating the filing fee only. The transaction valuation was calculated by adding the sum of (i) 165,124,117 issued and outstanding shares of common stock, par value $0.001 per share (the “Shares”), of CSRA Inc., a Nevada corporation (the “Company”), multiplied by the offer price of $41.25 per Share; (ii) 2,355,365 Shares issuable pursuant to options to acquire Shares from the Company and stock

appreciation rights to receive cash or Shares of the Company (“Company Stock Options”) with an exercise price less than the offer price of $41.25 per Share, multiplied by $17.81, which is the offer price of $41.25 per Share minus the weighted average exercise price for the Company Stock Options of $23.44 per Share; (iii) 691,531 Shares issuable pursuant to the Company’s restricted share unit awards granted pursuant to the CSRA Inc. 2015 Omnibus Incentive Plan whose vesting is conditioned in full or in part based on achievement of performance goals or metrics (the “Company PSUs”) multiplied by the offer price of $41.25 per Share; (iv) 1,014,530 Shares issuable pursuant to Company’s other restricted share unit awards granted pursuant to the CSRA Inc. 2015 Omnibus Incentive Plan (the “Company RSUs”) multiplied by the offer price of $41.25 per Share; and (v) 106,200 Shares issuable pursuant to the restricted stock unit awards granted pursuant to the CSRA, Inc. 2015 Non-Employee Director Incentive Plan (the “Director RSUs”) multiplied by the offer price of $41.25 per Share. The foregoing share figures have been provided by the Company to the Purchaser and are as of March 1, 2018, the most recent practicable date.

(2) 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 2018, issued August 24, 2017, by multiplying the transaction value by 0.0001245.
