("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 , 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) Mustang LLC I, as the sole general partner of Mustang I, SLTA, as the sole member of Mustang LLC I, and AIV GP, as the sole general partner of SLTA, may each be deemed to be the indirect beneficial owner of the securities directly owned by Mustang I under Rule 16a-1(a)(2) promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Each of Messrs. Durban and Mondre serve as a director of Mustang LLC I and Mr. Mondre serves as a director of AIV GP and each may be deemed to share voting and investment power with respect to the securities beneficially owned by Mustang I.
(3) (Continued from footnote 2) However, pursuant to Rule 16a-1(a)(4) of the Exchange Act, this filing shall not be deemed an admission that each of the Reporting Owners are beneficial owners of all securities covered by this filing, and each Reporting Owner (except for Mustang I) disclaims beneficial ownership of the securities held by Mustang I, except to the extent of such Reporting Owner's pecuniary interest therein, if any.
(4) Mustang LLC II, as the sole general partner of Mustang II, SLTA, as the sole member of Mustang LLC II, and AIV GP, as the sole general partner of SLTA, may each be deemed to be the indirect beneficial owner of the securities directly owned by Mustang II under Rule 16a-1(a)(2) promulgated under the Exchange Act. Each of Messrs. Durban and Mondre serve as a director of Mustang LLC II and Mr. Mondre serves as a director of AIV GP and each may be deemed to share voting and investment power with respect to the securities beneficially owned by Mustang II. However, pursuant to Rule 16a-1(a)(4) of the Exchange Act, this filing shall not be deemed an admission that each of the Reporting Owners are beneficial owners of all securities covered by this filing, and each Reporting Owner (except for Mustang II) disclaims beneficial ownership of the securities held by Mustang II, except to the extent of such Reporting Owner's pecuniary interest therein, if any.
(5) In accordance with an investment agreement, dated as of August 4, 2015, Mustang I and Mustang II are restricted from exercising the Issuer's 2.0% Convertible Senior Notes due 2020 (the "Convertible Notes") prior to the earlier of (i) the second anniversary of the date of issuance, (ii) such time as there is no director on the board of directors of the Issuer affiliated with any of Silver Lake and its affiliates (subject to certain exceptions) and (iii) in connection with or following a change of control of the Issuer, in each case, subject to certain exceptions described in footnotes (6) and (7) below.
(6) Exceptions to conversion restrictions described in footnote (5) include, (A) satisfying obligations related to pledged Convertible Notes, (B) following the one-year anniversary of issuance, if at any time the average of the daily volume weighted average price of the Issuer's common stock ("Common Stock") has exceeded $85 per share over ten consecutive trading days (at any time) the holders may convert up to 20% of the principal amount of the Convertible Notes, and
(7) (Continued from footnote 6) (C) the holders may convert up to 50% of the principal amount of the Convertible Notes if the Issuer exercises its right to require that one director affiliated with any of Silver Lake and its affiliates resign from the board of directors of the Issuer after 18 months following the date of issuance if, at such time, Mustang I and/or Mustang II beneficially owns Convertible Notes which would, upon conversion, equal at least 75% of the Common Stock which would have been received upon a conversion of the Convertible Notes beneficially owned by Mustang I and/or Mustang II immediately following the issuance of the Convertible Notes.
(8) The Convertible Notes mature on September 1, 2020, subject to earlier repurchase or conversion in accordance with their terms.
(9) Upon conversion of the Convertible Notes, the Issuer will deliver, at its election, cash, shares of 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 shares of Common Stock by delivering a number of shares of Common Stock at the initial conversion rate of 14.5985 shares of Common Stock (the "Conversion Rate"), and cash in lieu of fractional shares of Common Stock, per $1,000 principal amount of Convertible Notes. The initial conversion rate is subject to adjustment from time to time upon the occurrence of certain customary events in accordance with the terms of an indenture, dated as of August 25, 2015, by and between the Issuer and the Bank of New York Mellon Trust Company, N.A., as trustee.
(10) The initial Conversion Rate is equivalent to an initial conversion price of approximately $68.50 per share of Common Stock.
(11) These securities are directly held by Mustang I. See footnotes (2) and (3).
(12) These securities are directly held by Mustang II. See footnote 4.
