Dear Molly,

I am delighted to extend you this offer of employment with Teradata Corporation and its affiliates (“Teradata” or “Company”) as Chief Legal Officer & Corporate Secretary, based in San Diego, CA, and reporting to Steven McMillan, Chief Executive Officer, effective November 1, 2020 (the "Effective Date").

Base Salary: Your base salary, as of the Effective Date, will be paid at an annualized rate of $410,000.00, less applicable taxes and withholdings, and paid to you on Teradata’s normal bi-weekly payroll schedule.

Management Incentive Plan (MIP): In addition to your new base salary, you will participate in Teradata’s Management Incentive Plan (the “MIP”). Teradata's MIP is a performance-based annual incentive program for executive officers. Under the MIP, the Compensation and Human Resource Committee of the Board (the "Committee") establishes an annual bonus program based upon financial and/or strategic performance results achieved by Teradata, as well as your individual performance against your business objectives. As of the Effective Date, your new MIP target incentive opportunity shall equal 80% of your eligible gross base salary, which would bring your total targeted annual compensation to $738,000.00. In 2020, your annual target incentive will be prorated for the period of time you were in each role. MIP bonuses, if earned, will be paid in the first calendar quarter following the Plan year. No MIP award is guaranteed, and unless an exception applies as expressly set forth in the MIP, you must be employed by Teradata on the date MIP awards are paid to be eligible to receive an MIP award. The MIP is subject to amendment by Teradata in accordance with the terms of the Plan.

Annual Equity Award (Performance-Based / Restricted Share Units): You will continue to be eligible to participate in Teradata’s annual equity award program for executive officers. Annual awards are typically determined by the Committee together with the other independent members of the Board in the first quarter of each year and are generally compromised of a mixture of performance-based restricted share units (“PBRSUs”) and service-based restricted share units (“RSUs”). The precise nature of the award and vesting schedules will be determined by the Committee together with the other independent members of the Board in its discretion.

Subject to approval by the Committee, Teradata anticipates awarding you with a supplemental 2020 annual equity award with a target value of $1,000,000 (the “2020 Equity Award”). The actual number of shares for this supplemental 2020 Equity Award will be determined by dividing the target value by the preceding 20-day average of Teradata’s common stock prior to, but not including, the Effective Date. This supplemental 2020 Equity Award shall be effective November 2, 2020, the first business day following your promotion date and allocated 60% to PBRSUs (subject to a three (3)-year performance period commencing January 1, 2020 and achievement of the same goals applicable to other senior executives of Teradata) and 40% to RSUs (vesting in three (3) equal annual installments as of November 1, 2020). The Annual Equity Award will be governed by the terms and conditions of the Teradata 2012 Stock Incentive Plan, as amended (“Plan”) and your PBRSU and RSU equity award agreements, which you will be required to accept in connection with the award.

In addition, for avoidance of doubt, with respect to the settlement of the supplemental PBRSU award, the award will distribute any vested shares earned in connection with such awards promptly after the performance achievement is

certified by the Committee in the first quarter following the end of the applicable performance period. The RSU portion of this supplemental award will vest in three (3) equal annual installments aligned to the grant date of November 1, 2020.

Executive Severance Plan and Change in Control. You will continue to participate as a Level I participant in the Teradata Executive Severance Plan and a participant in the Teradata Change in Control Plan. These plans are subject to amendment or termination by Teradata in accordance with their terms, and your participation is subject to your signing a participation agreement under the ESP.

Stock Ownership Guidelines: Executive positions are subject to Teradata's Stock Ownership Guidelines holding requirement as established by the Committee (currently, 3X annual base pay for Officers), which are subject to change from time to time in the Committee’s discretion.

This letter, together with the Employee Confidential Information and Inventions Assignment Agreement you signed upon hire, forms the complete and exclusive statement of your employment agreement with Teradata.
