Explanation of Responses:

1. Prior to the consummation of the Issuer's initial public offering, First Data Holdings Inc. ("Holdings"), the direct parent company of the Issuer, merged with and into the Issuer with the Issuer being the surviving entity (the "Merger"). In connection with the Merger, all shares of Holdings' capital stock previously owned by the Reporting Persons (as defined below) will be converted into shares of Class B common stock of the Issuer and the Issuer will also effect a 3.16091-for-one reverse stock split of its capital stock (together with the Merger, the "Reorganization"). Each share of Class B common stock of the Issuer will be convertible into one share of Class A common stock of the Issuer automatically upon transfer, subject to certain exceptions. These securities have no expiration date.

2. O. Andreas Halvorsen, David C. Ott and Daniel S. Sundheim are Executive Committee members of certain management entities, including Viking Global Investors LP ("VGI"), Viking Global Performance LLC ("VGP") and Viking Long Fund GP LLC ("VLFGP"). VGI provides managerial services to various investment funds, including Viking Global Equities LP ("VGE"), Viking Global Equities II LP ("VGE II"), VGE III Portfolio Ltd. ("VGE III") and Viking Long Fund Master Ltd. ("VLFM", together with VGE, VGE II and VGE III, the "Viking Funds"; and the Viking Funds together with Mr. Halvorsen, Mr. Ott, Mr. Sundheim, VGI, VGP and VLFGP, the "Reporting Persons"). VGP is the general partner of VGE and VGE II and the investment manager of VGE III. VLFGP serves as the investment manager of VLFM.

3. VGI provides managerial services to (i) VGE, which directly holds 17,112,226 shares of Holdings Class B common stock that will convert into 5,413,702 shares of Class B common stock of the Issuer in the Reorganization; (ii) VGE II, which directly holds 1,003,650 shares of Holdings Class B common stock that will convert into 317,519 shares of Class B common stock of the Issuer in the Reorganization; (iii) VGE III, which directly holds 32,066,606 shares of Holdings Class B common stock that will convert into 10,144,738 shares of Class B common stock of the Issuer in the Reorganization; and (iv) VLFM, which directly holds 18,567,518 shares of Holdings Class B common stock that will convert into 5,874,105 shares of Class B common stock of the Issuer in the Reorganization.

4. Because of the relationships between VGI and the Viking Funds, VGI may be deemed to beneficially own the shares of Class B common stock directly held by the Viking Funds. VGP is the general partner of VGE and VGE II and the investment manager of VGE III. Because of the relationships between VGP and VGE, VGE II and VGE III, respectively, VGP may be deemed to beneficially own the shares of Class B common stock directly held by VGE, VGE II and VGE III.

5. VLFGP serves as the investment manager of VLFM. Because of the relationship between VLFGP and VLFM, VLFGP may be deemed to beneficially own the shares of Class B common stock directly held by VLFM.

6.
