Dear Donna:

On behalf of Sallie Mae (the “Company”), I am pleased to offer you employment in the position of Chief Marketing Officer. You will report to Raymond Quinlan, Chief Executive Officer. Your first day of employment will be on January 14, 2019, contingent upon any notice period required by your current or any prior employer.

Your annualized base salary of $450,000 will be paid bi-weekly. You will also be eligible for our employee benefits package. Your benefits coverage will take effect on the first calendar day of the month following your start date.

Starting in 2019, your annual bonus target will be 125% of your base salary, subject to the terms and conditions of the Company's Executive Management Incentive Plan (MIP). Bonus amounts for the 2019 performance period are paid in the first quarter of 2020; you must be employed with Sallie Mae on the date of payment to be eligible. We will share more information about the terms and conditions of this bonus plan after your start date.

You will also receive a one-time cash sign-on bonus of $550,000, less applicable taxes, to be paid on the pay date following 30 days of active employment. If you voluntarily terminate your employment or if your employment is involuntarily terminated by the Company prior to the satisfactory completion of one year of service, you agree to be liable to re-pay the Company for the entire $550,000 sign-on bonus granted. If your employment is voluntarily or involuntarily terminated after one year of service but less than two years of service, you will be liable to re-pay the Company for $275,000, which is 50% of the amount paid as a sign-on bonus. By signing your acceptance of the terms of this offer, you agree to repay all monies owed to the Company within 30 days of the effective date of your voluntary or involuntarily termination.
