Management Incentive Plan: You will be eligible to participate in Teradata’s Management Incentive Plan (the “MIP”), 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 each eligible employee’s individual performance against their business objectives. Your MIP target incentive opportunity shall equal 125% of your eligible gross base salary, which would bring your total targeted annual incentive compensation opportunity to $1,000,000. The period of your eligibility under the MIP will begin upon your start date of employment. The first plan year of your incentive opportunity will be pro-rated based on the time you are active in the plan year. Incentive awards are subject to discretionary adjustment by the Committee together with the other independent members of the Board as outlined in the MIP and, if earned, are paid in the first calendar quarter following the program year. Historically, annual incentive awards under the MIP have been paid out in cash.

Annual Equity Award (Performance-Based / Restricted Share Units): You will 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. Your annual equity award for 2020 shall have a target value of $8,500,000 (the “2020 Equity Award”). The actual number of shares for your 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 date of formal Board approval of your appointment. The 2020 Equity Award shall be effective the first business day following your hire 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). The 2020 Equity Award will be governed by the terms and conditions of 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, Teradata’s standard practice with respect to the settlement of PBRSU awards is to 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. Notwithstanding the foregoing, in the event that

the Company terminates your employment without Cause (as defined in the Teradata 2012 Stock Incentive Plan, as amended (the “Plan”)) and not as a result of your disability or death, or you resign from the Company for Good Reason (as defined below), then you shall be entitled to pro-rated vesting of the PBRSUs and RSUs underlying the 2020 Equity Award, determined under the pro-ration methodology employed by the Company from time-to-time (provided that your years of vesting service for this purpose only shall be no less than 2 years) and, in the case of PBRSUs for which the applicable performance period has not been completed as of the date of termination, subject to actual achievement of the applicable performance goals, as determined by the Committee after the end of the performance period.

“Good Reason” means the occurrence of any of the following events without your prior written consent in the event they are not remedied by the Company within thirty (30) days after receipt of written notice thereof given by you to the Company’s General Counsel: (a) a material reduction in your authority, duties and responsibilities, excluding for this purpose any isolated, insubstantial and inadvertent action not taken in bad faith; (b) any reduction in your annual base salary; (c) the failure to pay annual or long-term incentive compensation to which you are otherwise entitled under the terms and conditions of the applicable Company incentive plan, at the time at which such compensation is otherwise payable in the ordinary course of business or as soon thereafter as administratively feasible; (d) a reduction of five percent (5%) or more in your “target” or “maximum” annual or long-term incentive opportunity (other than any such reduction that is applied across-the-board to senior executives of Teradata); (e) the failure by the Company to continue in effect any equity compensation plan in which you participate, unless a substantially equivalent alternative compensation arrangement (embodied in an ongoing substitute or alternative plan) has been provided to you, or the failure by the Company to continue your participation in any such equity compensation plan on substantially the same basis, in terms of the level of your participation relative to other participants, excluding for this purpose any isolated, insubstantial and inadvertent action not taken in bad faith; or (f) except as required by law, the failure by the Company to continue to provide to you employee benefits substantially equivalent, in the aggregate, to those enjoyed by you under the qualified and nonqualified employee benefit and welfare plans of the Company, including, without limitation, the life insurance, medical, dental, health and accident, disability retirement, and savings plans, other than a reduction of such benefits, in the aggregate, of less than 5% of aggregate value of such benefits.

New Hire Grant Restricted Stock Unit Award: Teradata shall award you a one-time grant of service-based RSUs (the “New Hire Grant”) with a target value of $4,662,327, which is equal to the product of (i) the number of share units that you will forfeit upon resignation from your current employer, which we agree equals 36,096 share units, and (ii) the preceding 20-day average of your current employer’s common stock prior to, but not including, the date of formal Board approval of your appointment (the “Target Value”). The actual number of RSUs for your New Hire Grant 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 date of formal Board approval of your appointment. The New Hire Grant will be effective the first business day following your hire date and vest as follows: (i) 45% of the RSUs on December 1, 2020, (ii) 42% of the RSUs on the first anniversary of the date of grant, and (iii) the remaining RSUs (i.e., 13% of the RSUs) on the second anniversary of the date of grant, in each case subject to your continued employment with Teradata and subject to the other terms and conditions set forth in the applicable equity award agreement. Notwithstanding the foregoing, in the event that the Company terminates your employment without Cause (as defined in the Plan) and not as a result of your disability or death, or you resign from the Company for Good Reason (as defined above), then any unvested portion of the New Hire Grant shall vest in full.

If, after receipt of your signing bonus, your employment is terminated for Cause (as defined in the Plan) or if you terminate your employment for any reason other than Good Reason (as defined above) within twelve (12) months of your first day of employment with Teradata, you agree to repay $250,000 (net of taxes) of the signing bonus, and Teradata may withhold these sums from any compensation otherwise due to you. If your employment is terminated for Cause (as defined in the Plan) or if you terminate your employment for any reason other than Good Reason (as defined above) between twelve (12) and twenty-four (24) months of your first day of employment with

Executive Severance Plan and Change in Control Plan: You shall participate as a Level I participant in the Teradata Executive Severance Plan (the “ESP”) and shall participate under the Teradata Change in Control Severance Plan (the “CIC Plan”). You shall be designated by the Committee as an eligible participant in both plans effective upon your start date of employment with Teradata; however, each plan is subject to amendment or termination by Teradata in accordance with the terms of each plan, and your participation in the ESP is subject to your signing a participation agreement under the ESP. A copy of each plan, as well as the participation agreement for the ESP reflective of the provisions of this offer letter, will be provided to you under separate cover.

Your participation agreement under the ESP shall provide that (i) a Qualified Termination (as defined in the ESP) includes termination of your employment by you for Good Reason (as defined above) at any time (and not just in connection with a change in control), and (ii) upon a Qualified Termination (as defined in the ESP and as modified by the foregoing clause (i)), in addition to any applicable vesting provided for under Section 4(b)(v) of the ESP or the applicable award agreement, and subject to the terms and conditions of the ESP, with respect to any outstanding but unvested PBRSUs or RSUs, (a) you will be treated as having attained age 55 at the time of your termination of employment for purposes of determining the vesting of such awards under Section 4(b)(v) of the ESP, and (b) the additional year of vesting credit provided under Section 4(b)(v)(ii) of the ESP for purposes of calculating the vesting of RSU awards shall also be provided to you for purposes of determining the vesting of PBRSU awards, provided that payout of any such PBRSUs shall be subject to actual performance results as determined by the Committee after the end of the applicable performance period.

Travel Allowance: Because your principal place of employment will be Teradata’s office in San Diego, California when you are not otherwise traveling for business, subject to Committee approval, you will be eligible to commute to San Diego to perform your duties hereunder. You shall receive a gross monthly allowance of $15,000 to cover these commuting costs, such as the cost of airfare, lodging and a rental car or ride services (the “Allowance”). The Allowance shall be treated as taxable compensation to you but shall not be considered a part of your normal or expected compensation for purposes of calculating severance payments, bonuses, long-service awards or retirement benefits or similar payments. The Company shall have no other obligation to reimburse you for any costs related to your commuting expenses, nor will it assume any liability for lease agreements should you wish to lease an apartment. The Allowance may be revisited by the Committee on an annual basis.
