Dear Mr. Fountain:

I am pleased to offer you the position of Senior Vice President, Vice General Counsel with the Tennessee Valley Authority ("TV A"). This position is responsible for the administration and operational functions of the legal office and providing guidance to General Counsel regarding enterprise legal strategies, risks, and likely outcomes. This position will also support General Counsel in carrying out Corporate Secretary functions. The targeted start date for your TVA employment is Monday, June 1, 2020.

Upon employment in this position, TVA will provide you an annual salary of $450,000, which will be payable on a biweekly basis.

Additionally, you will be included as a participant in TVA's Executive Annual and Long-Term Incentive Plans. Under the Annual Incentive Plan, your annual incentive opportunity will be 55 percent of your annual salary beginning in fiscal year 2020 (October 1, 2019 through September 30, 2020). Actual award amount will be prorated based on the number of months you are employed during the fiscal year and based on achievement of goals established at the beginning of the performance period.

Under the Long-Term Incentive Plan, performance and retention awards are granted annually on October 1st for three-year periods. Effective October 1, 2020, you will receive a Long-Term Performance grant of $375,000 for the FY 2020 -FY 2022 performance cycle, which is equivalent to 2/3 of an initial employment grant of $562,500. The full amount will vest on September 30, 2022. Effective October 1, 2020, you will

also be eligible to receive a Long-Term Performance grant for the FY 2021 -FY 2023 performance cycle.

The full amount will vest on September 30, 2023. Actual long-term performance award amounts will be based on scorecard results.

Effective October 1, 2020, you will receive a Long-Term Retention grant of $249,000 for the three-year period FY 2021 -FY 2023. This grant will vest in 1/3 increments: $83,000 on September 30, 2021, $83,000 on September 30, 2022, and $83,000 on September 30, 2023.

Annual and long-term performance incentive awards are generally paid out in the first quarter of the fiscal year following the fiscal year in which they are earned. Eligibility for each award payment requires that you be employed by TV A on the vesting date for that payment.

In connection with your move to Tennessee, TVA will pay for the actual and reasonable travel and moving expenses, including home closing costs, for you and your immediate family. TVA's relocation services program will also be available to assist you in the sale of your present home. These relocation benefits must be repaid in full to TV A if, within one year of the effective date of your employment, (i) you voluntarily terminate employment unless the separation is for reasons beyond your control and acceptable to TVA, or (ii) if you are terminated for cause.

In addition to relocation benefits, TVA will provide you a relocation incentive payment in the total amount of $250,000, which will be paid to you in two lump sum payments, less any applicable taxes and withholdings. The first payment of $150,000 will be made as soon as practical following the commencement of your

employment and the second payment of $100,000 will be made one year following your date of employment. The first recruitment and relocation incentive payment must be repaid in full to TV A if, within two years of the effective date of your employment, (i) you voluntarily terminate employment unless the separation is for

reasons beyond your control and acceptable to TV A, or (ii) you are terminated for cause. The second

Eligibility for each installment requires that you be employed by TV A on the vesting date for that payment.

Unless TVA provides a severance plan or a change-in-control plan that provides greater benefits, in

which case you will be entitled to those greater benefits, subject to eligibility and other plan provisions, if your employment with TVA is terminated without cause, TVA will pay you a lump-sum payment in an amount equal to one years' annual salary as soon as practical following the termination of your employment.

negligence that directly results in significant economic or reputational harm to TVA.

During your employment, you will be eligible to participate in all TV A-sponsored employee benefits plans

and qualified retirement plans available to new management and specialist employees at TVA. Information and materials regarding these plans, including the benefits provided under them, will be provided to you.
