Offer Letter between Kathy Cullen-Cote and the Company dated on June 21, 2019

I am delighted to extend you this offer of employment with Teradata Corporation and its affiliates (“Teradata” or “Company”) as Chief Human Resources Officer, based in San Diego, and reporting to Oliver Ratzesberger, President and Chief Executive Officer.

This letter outlines the key elements of your compensation and related arrangements. Since your role will be as an executive officer with Teradata, all outlined compensation elements are subject to the review and formal approval of the Compensation and Human Resource Committee of Teradata’s Board of Directors (the “Committee”), and your appointment as an executive officer is subject to the review and formal approval by Teradata’s Board of Directors.

Base Salary: Your base salary will be paid at a rate of $450,000 on an annualized basis, less payroll deductions and withholdings, and paid on the Company’s normal payroll schedule.

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 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. We are recommending to the Committee that it approve an MIP target incentive opportunity of 80% of your eligible gross base salary, which would bring your total targeted annual incentive compensation to $360,000. The period of your eligibility under the MIP will begin the first full month following your start date of employment, and your incentive opportunity will be pro-rated based upon the portion of your base salary earned during your eligibility period. Incentive awards are subject to discretionary adjustment by the Committee as outlined in the MIP and, if earned, are paid in the first calendar quarter following the program year.

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 in the first quarter 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 in its discretion. Teradata anticipates granting you an Annual Equity Award for 2019, consisting of PBRSUs and RSUs with a grant date value of $2,200,000, subject to approval by the Committee. This Annual Equity Award would be effective the 1^st of the month following your hire date. The grant would be split between PBRSUs (70%) and RSUs (30%), with the PBRSUs subject to a three (3)-year cliff vesting period and the RSUs vesting in three (3) equal annual installments. For clarity, going forward beginning in 2020, you will be granted annual equity awards under the Company’s annual equity award program for executive and such awards will not be pro-rated in value. 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, 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.

New Hire Grant Restricted Stock Unit Award: Subject to approval by the Committee, Teradata anticipates awarding you a one-time grant of service-based RSU’s with a grant value of $2,200,000 (“New Hire Grant”). The actual number of RSUs for your New Hire Grant will be determined by taking the value of the award on the effective date of grant and dividing it by the preceding 20-day average of Teradata stock but not including, the date of the grant (the “New Hire Equity Effective Date”). The New Hire Grant will vest in one-third increments on each anniversary of the New Hire Equity

Effective Date until vested in full at the end of a three-year period, subject to your continued employment with Teradata on each applicable vesting date and other terms and conditions set forth in the Plan and your equity award agreement.

Cash Signing Bonus: You are eligible to receive a one-time cash signing bonus in the amount of $300,000, minus applicable taxes and withholdings. This sum is payable in the first payroll cycle after you have completed thirty (30) days of continuous and satisfactory employment with Teradata. However, your signing bonus is not considered earned until you have completed twelve (12) continuous months of employment with Teradata.

If your employment is terminated for Cause or if you terminate your employment for any reason between twelve (12) and twenty-four (24) months of employment of your first day of employment with Teradata, you agree to repay $100,000 of the signing bonus, and Teradata may withhold these sums from any compensation otherwise due you. For purposes of this agreement, “Cause” shall have the same definition set forth in Teradata’s 2012 Stock Incentive Plan.

Stock Ownership Guidelines: Executive positions are subject to Teradata's Stock Ownership Guidelines holding requirement as established by the Committee (currently, 35,000 shares), which are subject to change from time to time in the Committee’s discretion.

Officer/Executive Severance Plan and Change in Control: We will recommend to the Committee that you be eligible to participate as a Level I participant in the Teradata Executive Severance Plan (the “ESP”) and as a participant under the Teradata Change in Control Severance Plan (the “CIC Plan”). We anticipate that you would 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, will be provided to you under separate cover.

Relocation: It is currently expected that, after an initial two (2) year period, you will be relocated under a managed move and eligible for reimbursement of up to $200,000 for moving and relocations expenses that are incurred during your relocation. Relocation expenses covered include: a return house hunting trip to San Diego for you and your immediate family, lodging, transportation, and household goods shipping, shipment of 2 cars, and 30 days of temporary housing prior to your formal relocation. You must complete the necessary expense forms, pursuant to Teradata’s expense reimbursement policies and procedures, within thirty (30) days of incurring the associated expense. Upon mutual agreement concerning the exact timing of your relocation after the initial two (2) year period after you start employment with Teradata, your relocation process will be initiated, and a relocation counselor will be in contact with you to discuss your personal relocation needs. You should not incur any relocation expenses or initiate any relocation plans until you have discussed your situation with your assigned relocation counselor. If: (i) your employment is terminated by Teradata for Cause, or (ii) you terminate your employment for any reason, in either case within two (2) years of the date of first disbursement of any relocation monies or the completion of your relocation (whichever is later), you will be required to repay to Teradata the full relocation costs and any relocation expenses paid to you or on your behalf, and Teradata may withhold these sums from any compensation otherwise due you, consistent with applicable law. If you voluntarily cancel your relocation for any reason, you must repay all relocation reimbursements and allowances provided during the relocation process, including all expenses which were billed directly to Teradata.

Travel Allowance: Because you are generally expected to work from Teradata’s office in San Diego when you are not otherwise traveling for business, subject to Committee approval, you will be eligible to commute to San Diego as a company business expense. Such benefits include commuting cost of airfare, lodging and a rental car or ride services. Travel expenses will be reimbursed upon receipt, in accordance with the Company’s Travel and Expense Policy not to exceed $5,000 per month. The Company will not assume any liability for lease agreements should you wish to lease an apartment. You shall be responsible for payment of all applicable income tax in connection with such expenses directly paid for by the Company or reimbursed to you by the Company.

Tax Matters: Teradata agrees to reasonably cooperate with you to amend your offer letter to the extent you deem necessary to avoid imposition of any additional tax under Section 409A of the Internal Revenue Code, as amended, but only to the extent such amendment would not have a more than de minimis adverse effect on Teradata and is approved by the Committee. Notwithstanding any other provision of your offer letter, Teradata may withhold from any amounts payable hereunder, or any other benefits received pursuant hereto, such minimum federal, state and/or local taxes as shall be required to be withheld under any applicable law or regulation.

Benefits: As an employee of the Company, you will be eligible to participate in the standard benefit plans offered to similarly situated employees by Teradata from time to time, subject to plan terms and generally applicable company policies. A full description of these benefits is available for your review. Teradata may change its benefit programs from time to time in its discretion.
