(1) This Form 4 is filed on behalf of SLP IV Mustang Holdings, L.P. ("Mustang I"), SLP IV Mustang Holdings II, L.P. ("Mustang II"), SLP IV Mustang GP, L.L.C. ("Mustang LLC I"), SLP IV Mustang GP II, L.L.C. ("Mustang LLC II"), Silver Lake Technology Associates IV Cayman, L.P. ("SLTA") and Silver Lake (Offshore) AIV GP IV, Ltd.

Each of Mustang I, Mustang II, Mustang LLC I, Mustang LLC II, SLTA and AIV GP may be deemed to be a director by deputization of the Issuer.
(2) Represents the approximate conversion price of the Issuer's 2.0% Convertible Senior Notes due 2020 (the "Convertible Notes"), based on the conversion rates calculated pursuant to the Indenture, dated as of August 25, 2015 (the "Indenture"), by and between the Issuer and the Bank of New York Mellon Trust Company, N.A., as trustee.
(3) On September 5, 2018, Mustang II and the Issuer entered into a Convertible Notes Purchase Agreement pursuant to which the Issuer purchased $200,000,000 principal amount of Convertible Notes from Mustang II for aggregate consideration of $368,855,436.80. The number of shares of common stock of the Issuer ("Common Stock") underlying the $200,000,000 principal amount of Convertible Notes sold to the Issuer was approximately 2,965,040, based on the current conversion rate of 14.8252 shares of Common Stock, and cash in lieu of fractional shares of Common Stock, per $1,000 principal amount of Convertible Notes,, as calculated pursuant to the terms of the Indenture.
(4) Pursuant to the terms of an investment agreement, dated as of August 4, 2015, the Convertible Notes became convertible by Mustang I and Mustang II on August 4, 2017, subject to certain exceptions.
(5) The Convertible Notes mature on September 1, 2020, subject to earlier repurchase or conversion in accordance with their terms.
(6) Upon conversion of the Convertible Notes, the Issuer will deliver, at its election, cash, 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 Convertible Notes if the Issuer elects to settle its conversion obligation solely through the delivery of shares of Common Stock and cash in lieu of fractional shares of Common Stock, per $1,000 principal amount of Convertible Notes, based on the current conversion rate of 14.8252 shares of Common Stock, and cash in lieu of fractional shares of Common Stock, per $1,000 principal amount of Convertible Notes.
