On September 27, 2011, the Board of Directors, upon the recommendation of the Corporate Governance and Nominating Committee, approved an amended and restated Code of Business Conduct and Ethics (the "Code of Ethics"). The Code of Ethics applies to our directors, officers and employees, including our principal executive officer, principal financial officer and principal accounting officer. We have amended the Code of Ethics primarily to add provisions regarding corporate social responsibility, to update or remove certain provisions, including those that are addressed by other Company policies or in the Company's employee handbook, and to improve its readability and comprehension for employees. No substantive amendment to any element of the "code of ethics" definition enumerated in Item 406(b) of Regulation S-K was effectuated as a result of the amendment and restatement of the Code of Ethics. This summary is qualified in its entirety by reference to the full text of the Code of Ethics.
