Celanese expects its directors, officers and employees to adhere to three principles of business conduct in their daily business affairs:

1. Compliance with Applicable Laws and Internal Policies –Celanese directors, officers and employees will obey all laws and regulations applicable to the Company’s activities as well as internal policies, both global and regional, and they will not take any action on the Company’s behalf that they know or should know violates any law, regulation or internal policy.

2. Loyalty to the Company – Celanese directors, officers and employees will not put ourselves in a position where their personal interests or relationships conflict or may appear to conflict with the best interests of the Company.

3. Observance of Ethical Standards of Society – Celanese directors, officers and employees will follow the ethical standards of our societies while conducting the Company’s business.

Celanese’s global Business Conduct Policy ensures that all directors, officers and employees share Celanese’s commitment to ethical business practices, and provides guidance on how to put this commitment into practice. It also helps to ensure that we are adhering to the ethical standards and laws in all regions where we operate. Celanese’s Financial Code of Ethics sets forth additional ethical standards that our Chief Executive Officer, Chief Financial Officer and Chief Accounting Officer must follow in connection with our public disclosures.

We don’t take our commitment to the global Business Conduct Policy lightly. Achieving its standards is the best thing we do year after year.
