PERSONAL AND CONFIDENTIAL Revised June 23, 2017 Ms. Reema Poddar Dear Reema, I am delighted to extend to you this offer of employment with Teradata Corporation and its affiliates (“Teradata” or “Company”) as Senior Vice President, Product Development reporting to Oliver Ratzesberger, EVP and Chief Product Officer. The position is located and expected to work from our offices in the San Diego, California area. In this position, you will be paid at an annualized rate of $425,000; this equates to a weekly rate of $8,173.08. Because we operate on a bi-weekly pay schedule, you will be paid two weeks’ salary five days following the close of each pay cycle. In addition to your base salary, you will be eligible to participate in Teradata’s Annual Incentive Plan (“AIP” or “Plan”). Teradata’s AIP is a performance-based annual incentive program based on financial and strategic performance results achieved by Teradata, as well as your individual performance against objectives. In this position your target annual AIP incentive opportunity is 70% (seventy percent) of your eligible earnings. You will be eligible the first of the calendar quarter following your start date, except if you start before the end of July 2017, you will be eligible August 1, 2017, and your 2017 AIP will be pro- rated according to the number of months in the calendar year you are eligible under the Plan. For the 2017 Plan year you will be guaranteed a minimum AIP payment of 80% (eighty percent) of your pro- rated target payment (the “2017 AIP Guarantee”). Your actual payment will be based on the greater of 80% of your pro-rated target annual incentive or your pro-rated annual incentive based on actual results achieved by the Company. Except for the minimum guarantee of payment, all AIP payments are subject to the terms and conditions of the plan guidelines. You will also be eligible for a one-time sign-on bonus of $100,000 (gross) payable ninety (90) days following your date of hire. You will earn the sign-on bonus after 24 (twenty-four) months of continuous, full-time, active employment with the Company. Should you leave the Company for any reason before your 24th month of continuous, full-time, active employment, you will be obligated to repay 100% of the sign-on bonus prior to your last day of active employment. Contingent upon your acceptance of this offer and approval by the Company’s Compensation and Human Resource Committee, you will be granted an equity award with a total value of $1,050,000 to be delivered in Service-Based Restricted Share Units as described below. The effective date of the grant for this award will be the first day of the month following your start date with Teradata (“Equity Effective Date”). Service-Based Restricted Share Units On the Equity Effective Date, Teradata will grant you Service-Based Restricted Share Units (the “Units”) with a value of $1,050,000. The actual number of Units shall be determined by taking the value of the award and dividing it by the average closing price of Teradata common stock for the twenty (20) trading days immediately preceding, but not including, the Equity Effective Date. The result shall be rounded to the nearest whole unit. Page 1 of 5

The Units will vest one-third (1/3) on each anniversary of the Equity Effective Date until vested in full at three (3) years, subject to your continued employment with Teradata on each applicable vesting date. The Units will be subject to approval by the Compensation and Human Resource Committee of the Teradata Board of Directors. In addition, subject to the approval of the Compensation and Human Resource Committee, concurrent with the Company’s annual equity award program provided to other eligible employees, which generally takes place in Q4 each year you will be granted an annual equity award in Q4 2017 with a total value of $500,000 delivered in the form of award that is consistent with all other awards provided to similarly situated employees (“Annual Equity Award”). The Annual Equity Award is a guarantee only for the 2017 award and requires that the Company does not otherwise cancel or postpone its annual award program for other similarly situated employees, in which case your Annual Equity Award will be treated consistent with other similarly situated employees. Your equity awards will be issued under the terms of Teradata’s Stock Incentive Plan, which is administered by Fidelity Investments. The specific terms and conditions relating to the award will be outlined in the applicable award agreement contained on Fidelity’s website. Within two weeks after your Equity Effective Date, your grant will be loaded to Fidelity’s system. You can access your grants at www.netbenefits.com. Please review the grant information, including the applicable grant agreements, carefully and indicate your acceptance by clicking on the appropriate button. IMPORTANT NOTICE: You must accept your award online in accordance with the procedures established by the Company and the Plan administrator. By accepting your award in accordance with these procedures, you acknowledge that a copy of the Teradata 2012 Stock Incentive Plan (the “Plan”), the Plan Summary and Prospectus, and the Company's most recent Annual Report and Proxy Statement (collectively, the "Prospectus Information") either have been received by you or are available for viewing on the Company's intranet site at HReXpress (located in the “Related Links” section of the Management Stock Options / Restricted Shares page), and you consent to receiving this Prospectus Information electronically, or, in the alternative, agree to contact Global Compensation, to request a paper copy of the Prospectus Information at no charge. By accepting your award, you also represent that you are familiar with the terms and provisions of the Prospectus Information and that you accept the award on the terms, and subject to the conditions, set forth in the applicable grant agreement for your award and in the Plan. Failure to accept your award may result in its cancellation. The Company currently has a Key Employee Severance Plan (“Plan”), and you will be recommended to the Company’s Compensation and Human Resources Committee (“CHRC”) for eligibility to participate in the Plan. The Plan, at the discretion of the CHRC, is subject to review, modification or cancellation. Because your position is located in San Diego, you will be eligible for relocation benefits under Teradata’s Relocation Policy. The expectation is that you will relocate no later than March 31, 2018. Upon acceptance of this offer your relocation process will be initiated and a relocation counselor will contact you to discuss your personal relocation needs. You will be required to sign and return a Relocation Repayment Agreement prior to any relocation related expenses being reimbursed or remitted on your behalf. In advance of executing this agreement and speaking with a relocation counselor we ask that you please not incur any relocation expenses or initiate any relocation plans.

By signing this offer letter, you will indicate your agreement to Teradata’s stipulations about relocation expenses. Page 2 of 5
