Dear ONE Gas Employees,

ONE Gas has earned a reputation as a company with integrity. Integrity matters to our customers, regulators, investors, employees and to the communities we serve. This reputation can serve as a valuable company asset, one that needs to be developed and sustained over time. Our employees take tremendous pride in doing the right thing every day when performing their job duties.

In today's fast-paced society where news is spread almost instantaneously around the world, we, like all businesses, find ourselves operating under more scrutiny than at any other time in history.

The following Code of Business Conduct and Ethics provides guidelines for ethical issues that may arise when dealing with fellow employees, customers, suppliers, competitors, federal and state agencies or officials, or the general public. It is the responsibility of each ONE Gas board member, officer and employee to understand and adhere to the guidelines outlined in the Code.

Please take time to read through the following pages and think about how the Code pertains to you and your workplace. It is my hope, as well as the hope of our leadership team, that the Code will be a valuable tool for you when you are faced with ethical dilemmas. If you have questions or concerns after reviewing the Code, please do not hesitate to talk to your supervisor or the Chief Compliance Officer to receive clarification.

With your continued dedication and commitment, we can maintain and further enhance our reputation as a company that operates with integrity.

Sincerely,

Sid McAnnally
President and Chief Executive Officer,
ONE Gas, Inc.
