On June 25, 2019, in connection with the amendments to the Third Amended and Restated Certificate of Incorporation, the Board amended and restated the Company’s Fourth Amended and Restated
Bylaws effective immediately to make certain related administrative and conforming changes. The Company’s Fourth Amended and Restated Bylaws reflect: the elimination of the supermajority stockholder vote requirement to amend the Bylaws, replacing
such standard with a majority vote requirement; the declassification of the Board by 2022 and related ability to remove directors with or without cause; the removal of provisions that have become obsolete, including as a result of CCMP L.P. and
certain of its affiliates no longer owning any shares of the Company’s stock; and other minor conforming, clarifying or administrative language changes.
