**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Orogen Echo LLC ("OE") directly owns the reported securities. The Orogen Group LLC ("Orogen") is the sole member of OE and Vikram S. Pandit ("Mr. Pandit") is the Chairman and Chief Executive Officer of Orogen and serves on the board of directors of ExlService Holdings, Inc. (the "Issuer"). Orogen Holdings LLC and Atairos-Orogen Holdings, LLC are the sole members with joint investment control of Orogen. Mr. Pandit has majority voting control of Orogen Holdings LLC. Atairos Group, Inc. ("Atairos") is the sole voting shareholder of Atairos-Orogen Holdings, LLC. Michael Angelakis is the Chairman and Chief Executive Officer of Atairos and controls a majority of the voting power of Atairos Partners GP, Inc., which is the general partner of Atairos Partners L.P., the sole voting shareholder of Atairos.
(2)	Each of the Reporting Persons, other than Mr. Pandit, is acting as a director by deputization of the Issuer with respect to Mr. Pandit's membership on the board of directors of the Issuer. Each of the Reporting Persons may be deemed to have direct or indirect beneficial ownership of the reported securities, as applicable, but disclaims such beneficial ownership except to the extent of its pecuniary interest therein.
(3)	The aggregate principal amount of the reported securities is $150,000,000, and such reported securities are convertible at any time prior to the close of business on the scheduled trading day immediately preceding October 1, 2024, subject to earlier conversion or redemption in accordance with their terms.
(4)	Upon conversion of the reported securities, the Issuer will deliver, at the Issuer's election, cash, shares of common stock of the Issuer, par value $0.001 per share ("Common Stock") or a combination of cash and shares of Common Stock. This number represents the number of shares of Common Stock issuable upon conversion of the reported securities if the Issuer elects to settle its conversion obligation solely through shares of Common Stock by delivering a number of shares of Common Stock at the initial conversion rate of 13.3333 shares of Common Stock per $1,000 principal amount of the reported securities. The initial conversion rate is subject to adjustment from time to time in accordance with the terms of an indenture, dated as of October 4, 2018, by and between the Issuer and Citibank, N.A., as trustee.
