On April 23, 2013, in connection with the initial public offering of the Issuer, Serafina S.A. (the “BC Shareholder”), certain shareholders affiliated with Silver Lake Group, L.L.C. (the “Silver Lake Shareholder”), David McGlade and certain of his affiliated trusts and entities (the “McGlade Shareholder,” and, together with the Silver Lake Shareholder and the BC Shareholder, the “Shareholders”) and the Issuer entered into a governance agreement (as amended from time to time, the “Prior Governance Agreement”). In December 2018, this Prior Governance Agreement and other shareholders agreements were terminated, a new Governance Agreement was entered into between the Issuer and the BC Shareholder (as amended from time to time, the “Governance Agreement”) and a new shareholders agreement was entered into among the Issuer and the Shareholders (as amended from time to time, the “Shareholders Agreement”). Under the Governance Agreement, the BC Shareholder currently has the right to nominate two directors for election to the Issuer’s board of directors. Under the Shareholders Agreement, the BC Shareholder has drag-along rights with respect to the Silver Lake Shareholder and the McGlade Shareholder under certain circumstances and each of the Silver Lake Shareholder and the McGlade Shareholder has certain tag-along rights on transfers by the BC Shareholder.

Given the terms of the Shareholders Agreement, the Reporting Person, collectively with the Silver Lake Shareholder and certain related parties (collectively, the “SLP Parties”) and the BC Shareholder and certain related parties (collectively, the “Serafina Parties”), may be deemed to constitute a “group” that, as of the date hereof, collectively owns approximately 73,692,685 common shares, or approximately 52.6%, of the Issuer’s outstanding common shares for purposes of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Act”), assuming the conversion of all outstanding equity awards held by Mr. McGlade that are vested or that will vest within the next 60 days. The Reporting Person disclaims beneficial ownership of the common shares of the Issuer other than the shares reported on the cover page included herein. Pursuant to Rule 13d-1(k)(2) under the Act, the SLP Parties and the Serafina Parties are each filing separate Schedule 13Gs with respect to the common shares of the Issuer.

Not Applicable.
