Conflict of Interest

Encana expects employees, contractors and directors to avoid situations where personal interests could conflict, or appear to conflict, with their duties and responsibilities or the interests of Encana. A conflict of interest may occur where involvement in any activity, with or without the involvement of another party, prevents the proper performance of employee, contractor and director duties for Encana. A conflict of interest may also occur where involvement in any activity creates, or appears to create, a situation where judgment or the ability to act in the best interests of Encana is affected.

When faced with an actual or potential conflict of interest, employees, contractors and directors must comply with the Conflict of Interest Policy. Contractors must also comply with their written contracts. Supervisors will ensure that employees and contractors are not involved in any decision or operation related to a conflict.

Officers and directors must adhere to additional obligations as set out in relevant statutes and Encana’s By-laws and must inform the Chairman of the Board of Directors of any such conflict. The Chairman of the Board will ensure that the applicable officers or directors are not involved in any decision or operation related to a conflict.

Fair Dealing

Employees, contractors and directors should endeavour to deal fairly with Encana’s customers, suppliers, contractors, industry and business partners, employees and any other stakeholders .
