Exhibit 99.1 and Exhibit 99.2 (Joint Filer Information) are incorporated herein by reference. This Form 4 is the first of two Forms 4 being filed relating to the same event. The Form 4 has been split into two filings because there are more than 10 Reporting Persons in total, and the SEC's EDGAR filing system limits a single Form 4 to a maximum of 10 Reporting Persons. Each Form 4 will be filed by Designated Filer Thomas H. Lee Advisors, LLC.
