#### CORPORATE GOVERNANCE
Code of Ethics, Code of Conduct and Corporate Governance Guidelines

In accordance with applicable NYSE listing standards and SEC regulations, the Board has adopted a Code of Ethics, Code of Conduct and Corporate Governance Guidelines.

• any immediate family member of any of the foregoing persons;

• any person who is known to be the beneficial owner of more than 5% of any class of our voting securities; or

• any entity in which any of the foregoing persons is employed or is a partner or principal or in a similar
