Dear Peter:

I am delighted to extend to you an offer of employment with NCR Corporation as Senior Vice President, General Counsel and Secretary, with an anticipated Start Date of May 29, 2006 (“Start Date”). As you know, this offer is contingent on the approval of NCR’s Board of Directors. This position will be based in Dayton, and you will report directly to me and be a member of the NCR leadership team. Other details of the offer are as set forth below.

Annual Base Salary — Your annual base salary will be Three Hundred Eighty-five Thousand Dollars ($385,000) per year, commencing as of your effective Start Date. You will be paid on a bi-weekly pay schedule, one week in arrears.

Incentive Award – You will be eligible to participate in NCR Corporation’s Management Incentive Plan for Executive Officers (“MIP”), which provides year-end incentive awards based on the success of NCR Corporation in meeting annual performance objectives. For 2006, which has a payout in March 2007, you will be eligible for a target incentive award of 60% of your base salary, with a maximum potential payout of 2x target, pro-rated for the number of calendar months, or parts thereof, during which you are employed with NCR in 2006. You will also be eligible for a 10% incentive opportunity based on the achievement of specific diversity metrics in 2006, as determined by the Compensation & Human Resource Committee of the NCR Board of Directors.

Your annual performance and compensation, including any future equity awards, will be assessed and determined in Q1 of each year by the Compensation & Human Resource Committee, and are subject to approval by the NCR Board of Directors.

Hiring Grant – You will receive an equity grant with a value of $1,500,000, which will be delivered as follows: 50% in Performance-based Restricted Shares and 50% in NCR Corporation Stock Options. Additional details of the grant are as follows:

Performance-based restricted shares: Effective as of your Start Date, NCR Corporation will grant you performance-based restricted shares with a value of $750,000. The actual number of shares will be determined by taking the value of the award, or $750,000, and dividing it by the average of the high and low prices of NCR stock for each trading day during the thirty (30) calendar days preceding, but not including, your Start Date. The performance-based restricted shares will be subject to standard terms and conditions determined by the NCR Corporation Compensation & Human Resource Committee. The performance-based restricted shares are based on NCR Corporation’s performance over a 3-year term, as determined through the achievement of NCR Corporation’s cumulative

net operating profit. Based on actual company performance, participants can earn between 0% and 150% of the targeted number of shares at the end of the 3-year cumulative time period, provided you are still employed by NCR at that time.

Stock Options: Effective as of your Start Date, NCR Corporation will grant you nonqualified options to purchase shares of NCR Corporation common stock (the “Options”), with a value of $750,000. The actual number of options will be determined by taking the value of the award, or $750,000, and dividing it by the Black-Scholes value, or 39.9%, of the average of the high and low prices of NCR stock for each trading day during the thirty (30) calendar days preceding, but not including, your Start Date. The options will be subject to standard terms and conditions determined by the NCR Corporation Compensation & Human Resource Committee. The options will vest in 25% increments on each of the first four anniversaries of the Start Date, subject to your continued employment with the Company on each such anniversary date, and will have an expiration of 10-years.

Vacation – In recognition of your role and prior experience, you will be eligible for four weeks of paid vacation.

NCR Benefits – On your first day of employment with NCR, you will automatically receive core benefit coverage for yourself. NCR core benefit coverage includes: health care coverage, dental care coverage, short-term and long-term disability coverage, life insurance coverage, and accidental death and dismemberment insurance coverage. You will have the opportunity to design your own personalized benefit elections through the company’s flexible benefits program. Upon receipt of your signed offer letter and employment documentation, NCR will establish your payroll record which notifies the NCR Benefits Service Center to send a Benefits New Hire Package to your home address. You will have thirty (30) days from the date your benefits package is mailed to make your benefit elections. You also have this same thirty (30) day period to enroll eligible dependents, whose coverage will be made retroactive to your Start Date. Open enrollment is conducted in the Fall of each calendar year. At that time, you will have an opportunity to make benefits elections for the following year.

Additionally, you will be eligible to participate in the NCR Savings Plan (401(k)) and the NCR Employee Stock Purchase Plan. Information about each program will be provided in the Benefits New Hire Package.

Subject to applicable NCR policies, you may use the corporate aircraft for travel between your current residence and the Company’s offices in Dayton, Ohio. In addition, expenses related to your travel to, from or while in Dayton, Ohio will be reimbursed by NCR. In the event and to the extent such use or expenses are subsequently deemed for federal or state income tax purposes to be personal use or expenses, NCR will provide you a sufficient “gross-up” payment to cover all federal and state income taxes on such personal use, payable by NCR upon notice of the payment and amount due, no later than the day such taxes are due. It is intended that this be a full gross-up and that you have no after tax costs for the paid or reimbursed expenses and the gross-up thereon.

Executive Medical Exam Program – You will be eligible to participate in the Executive Medical Exam Program, which provides up to $5,000 on an annual basis for progressive, diagnostic analysis by NCR Corporation’s provider of choice. Additional information and specifics will be provided following your Start Date. This program is subject to amendment or termination by NCR.

This program is subject to amendment or termination by NCR.

Upon the termination of your employment for any reason whatsoever, you shall promptly deliver to NCR all documents, slides, computer tapes and disks (and all copies thereof) containing any Confidential Information.

Breach of Restrictive Covenants – You acknowledge and agree that the time, territory and scope of the post-employment restrictive covenants in this Agreement (the non-competition, non-solicitation, non-hire, confidentiality and non-disclosure covenants are hereby collectively referred to as the “Restrictive Covenants”) are reasonable and necessary for protection of NCR’s legitimate business interests, and you agree not to challenge the reasonableness of such restrictions. You acknowledge that you have had a full and fair opportunity to be represented by counsel in this matter and to consider these restrictions prior to your execution of this Agreement.

The arbitration shall be held in Dayton, Ohio, before an arbitrator who is an attorney knowledgeable of employment law.
