#### Corporate Governance Guidelines
Our Board adopted Corporate Governance Guidelines that outline, among other matters, the roles and functions of the Board, the responsibilities of various Board committees and the mission of the Board. Our Corporate Governance Guidelines can be found on the investor section of our website under " Governance—Governance Documents ." Information on our website does not constitute part of this Proxy Statement.

The Corporate Governance Guidelines provide, among other things, that:

• a majority of our Board must be independent

• the non-executive Chair presides over executive sessions of independent directors

• the Board appoints all members and chairpersons of the Board committees, including filling of vacancies, after the NCGC recommends appropriate candidates

• the Audit Committee, Compensation Committee, and NCGC consist of independent directors to the extend required under SEC and Nasdaq rules

• the independent directors meet at least quarterly in executive sessions without the non-independent directors or management

• independent directors may not serve on the boards of more than three other public companies or, with the permission of the Board, four; the CEO may not serve on more than one other public company board

• the Board and Compensation Committee annually review the succession plans of the CEO and senior management

• directors cannot disclose confidential information to any person or entity outside of the Company or use such information for personal benefit

• Board self-assessments are conducted annually and committee self-assessments bi-annually

• Board members are subject to a stock ownership policy (described below) to ensure that they have a meaningful financial stake in the Company

The Board monitors changing legal and regulatory requirements, evolving best practices and other developments. The Board modifies the Corporate Governance Guidelines and
