Explanation of Responses:

( 1 )The number of shares of class A common stock earned will be based on the percentage of budgeted EBITDA achieved in 2018, with a minimum of 50% of shares earned upon at least 70% achievement and 100% of shares earned upon at least 75% achievement. To the extent any shares of class A common stock are earned, 50% of such earned shares will vest on December 31, 2018 and the remaining 50% will vest on December 31, 2019. ( 2 )Restricted shares of Class A common stock granted under the Issuer's 2015 Amended and Restated Management Incentive Plan pursuant to the Amended and Restated Employment Agreement between the Issuer and Douglas A. Cifu, based on the volume weighted average price of the Issuer's Class A common stock on the three trading days preceding the grant date of 19.3216. ( 3 )Each restricted stock unit ("RSU") is granted under the Issuer's 2015 Amended and Restated Management Incentive Plan and represents a contingent right to receive one share of Class A common stock of the Issuer. ( 4 )The RSUs vest in three equal installments on January 23, 2019, January 23, 2020 and January 23, 2021. ( 5 )Pursuant to the terms of the Exchange Agreement, effective as of April 15, 2015, by and among the Issuer, Virtu Financial LLC and the equityholders of Virtu Financial LLC (the "Exchange Agreement"), Virtu Financial Units, together with a corresponding number of shares of Class C Common Stock, may be exchanged for shares of Class A common stock of the Issuer, which have one vote per share and economic rights (including rights to dividends and distributions upon liquidation), on a one-for-one basis at the discretion of the holder. The exchange rights under the Exchange Agreement do not expire. ( 6 )By a trust, for the benefit of the Cifu Family (the "Cifu Family Trust"). Melissa B. Lautenberg, the reporting person's wife, and Dr. Mitchel A. Lautenberg, Ms. Lautenberg's brother, share dispositive control and voting control over the shares held by the Cifu Family Trust. The reporting person may be deemed to beneficially own the shares held by the Cifu Family Trust by virtue of his relationship with Ms. Lautenberg. ( 7 )Each Option Award is granted under the Issuer's 2015 Management Incentive Plan and represents a contingent right to receive one share of Class A common stock of the Issuer. ( 8 )Options Awards vest in equal installments on each of the first four (4) anniversaries of April 15, 2015. Any fractional Option Award resulting from the application of the vesting schedule under the 2015 Management Incentive Plan will be aggregated and the Option Awards resulting from such aggregation shall vest on April 15, 2019.
