Director Independance

As a matter of policy, the Board believes that a substantial majority of the Directors should be independent. The Board adopts the definition of independence described in Exhibit B to the Teradata Corporation Board of Directors Corporate Governance Guidelines. The Board may amend this definition in the future; if it does, it will disclose the revised definition. On an annual basis, with input and a recommendation from the Committee on Directors and Governance, the Board will determine whether each outside Director meets the definition of independence and will disclose its determination. Currently, the Board believes there is no relationship between any outside Director and the Company that would be construed in any way to compromise any outside Director being considered independent.
