Dear Sophia,

I am pleased to extend this offer of employment to you for the role of Senior Vice President and Chief Product Officer reporting directly to Kevin Clark, President and Chief Executive Officer. As we have discussed, the role will be based in our Boston, Massachusetts office.

This employment offer confirms your annual target compensation of $3,500,000, as described below, as well as a brief summary of Aptiv sponsored plans and programs.

Base Salary: We are pleased to offer you an initial base salary at an annual rate of $750,000. Your base salary will be reviewed from time to time in accordance with Aptiv's normal practice.

Target Annual Incentive: You are eligible for our annual incentive plan. Your target annual incentive compensation will be 100% of your base salary ($750,000 at current target payout). The target has the potential to payout in a range of O - 200% depending on the company's performance relative to established metrics and targets. The actual amount you receive is adjusted depending on the company's and your individual performance, as appropriate.

Target Long-Term Incentive: Your annual long-term incentive target will be $2,000,000. This is an equity award granted annually in February and denominated in shares. The award will be allocated on the same basis as all officers of the company, which is currently 60% performance-based restricted stock units ("PRSUs") and 40% time-based restricted stock units ("RSUs"). The PRSU award is tied to Aptiv's performance against metrics (currently these are Average Return on Net Assets, Cumulative Net Income and Relative Total Shareholder Return). The PRSUs vest at the end of the third calendar year and will be distributed following confirmation of the company's performance by the Board of Directors. The RSU awards vest ratably on February 28th for each of the first three years following the date of grant. Your first annual equity grant will be issued in February 2022. As a condition of receiving your first long-term incentive grant, you will be required to sign a confidentiality and non-interference agreement, referenced in the form attached, to be provided to you for electronic acceptance at the time of the grant.

Sign-on Payments: Aptiv will provide you with a one-time cash payment and equity grant to replace the value of lost bonus payments and stranded equity. In addition, Aptiv is providing additional cash and equity value as an inducement to join the Aptiv team. The cash sign-on payment and equity grant totaling,$3,675,000 are comprised of the following:

•A one-time sign-on cash payment of $1,175,000. Payment of the cash sign-on will be made to you within 45 days of commencing active employment. In the event that you voluntarily terminate employment or are terminated with cause prior to the second anniversary of your employment date, the inducement portion of the payment will be subject to repayment in accordance with the attached agreement.

•A sign-on grant of time-based RSUs in the amount of $2,500,000. Your sign-on RSU grant will be issued in February 2022 and will vest ratably on February 28th for each of the first two years following the date of grant. In the event of a qualifying termination, or termination for good reason, as such terms are defined in Aptiv's Long-term Incentive Plan, prior to the initial vesting date, Aptiv will pay you a cash amount equal to
