By virtue of the Advent Directors' representation, for purposes of Section 16 of the Securities Exchange Act of 1934, each of the Reporting Persons may be deemed directors by deputization of the Issuer. The Advent Directors have filed separate Section 16 reports disclosing securities of the Issuer that they may be deemed to beneficially own for Section 16 purposes. Exhibit 99.1 (Footnotes to Form 4) and Exhibit 99.2 (Signatures and Joint Filer Information) are incorporated by reference.
