Dear Bill:

          We are pleased to offer you the position of President and Chief Nuclear Officer of PSEG Nuclear, LLC, a subsidiary of PSEG Power, LLC, effective January 1, 2007 (“DOE”). In this position, you will be an employee of PSEG Power. While you are employed by PSEG Power, you will devote substantially all of your business time and efforts to the performance of your duties and use your best efforts in such endeavors. Your acceptance of this offer of employment constitutes your representation that your execution and performance of the requirements of this position will not be in violation of any other agreement to which you are a party. PSEG Power is a subsidiary of Public Service Enterprise Group Incorporated (Enterprise or PSEG). You may be assigned to another executive position of similar or greater responsibility by the Chief Executive Officer of Enterprise.

          You will be paid a base salary of $500,000 and will be eligible for your first salary review in December 2007. Salary reviews will be conducted annually thereafter.

          Within 45 days following your DOE, PSEG Power will make a cash payment to you in the amount of $500,000 (subject to withholdings according to the IRS and Company policy). This bonus must be repaid, and you agree to repay it, if you leave the Company (voluntarily or are terminated for cause): within five (5) years of your DOE. In addition, if your 2006 annual incentive payment from Exelon Corporation is less than $230,000, you will receive a lump sum payment equaling the difference between $230,000 and such amount within ninety days.

          You will participate in PSEG’s Management Incentive Compensation Plan (MICP) under the terms and conditions of that Plan. Your target incentive award will be 60% of your base salary. You may, however, be eligible to receive up to 90% of your base salary

1 “Cause” means (i) the willful or negligent dereliction of, and continued failure by you to perform your dutieswith PSEG Power (other than any such failure resulting from your incapacity due to physical or mental illness),after a written demand for performance is delivered to you by the President - PSEG Power, L.L.C., whichidentifies the manner in which he believes that you have not so performed your duties; (ii) any conductconstituting a felony or moral turpitude; (iii) fraud or embezzlement; or (iv) failure to comply with the Standards of Integrity.

          You will be a participant in the Long-Term Incentive Plan (LTIP) of Enterprise and you will receive an initial grant of 50,000 shares of Restricted Stock of Enterprise, subject to the approval of the Organization and Compensation Committee of the Board. Under the LTIP, 20,000 shares will vest on the third anniversary of your DOE. The remaining 30,000shares will vest on the sixth anniversary of your DOE. All of the shares will vest in the event of your death or total and permanent disability or, if your employment is terminated without cause. You will be paid any dividends on the shares in cash. In addition, long-term compensation opportunity is reviewed annually pursuant to the terms of the LTIP. The first such review will take place in the first quarter of 2007, and is expected to provide total value of approximately $500,000. In the years thereafter, the number and form of LTIP grants recommended in any given year will appropriately reflect your responsibilities and ability to contribute to the long-term success of Enterprise.

          You are eligible for financial counseling on the same terms and conditions as applied to other officers of PSEG. You are also eligible to participate in the PSEG Deferred Compensation Plan For Certain Employees, which allows you to defer all or a portion of your base pay and/or any incentive bonus you may receive in any given year upon employment. You are also eligible for an executive annual physical examination arranged through PSEG’s Medical Department. In addition, you are eligible to receive thirty (30) vacation days with pay beginning January 2, 2007.

In addition, you are eligible for the following: You will be eligible to participate in the Limited Supplemental Benefit Plan for Certain Employees of Public Service Enterprise Group and its Subsidiaries (“the Limited Plan”)if you remain employed by PSEG through January 16, 2013. Upon your retirement, The Limited Plan will provide a target supplemental pension. For example, if you complete 10 years of service with the Company upon your retirement, the Plan will provide retirement income equal to 40% of your final average earnings less the aggregate of 1) your actual pension provided by the Cash Balance Plan, b) your vested Exelon pension at your DOE and c) your primary Social Security benefit payable at normal retirement age. In addition, the Plan provides a supplemental death benefit equal to 150% of base compensation if death occurs while employed and before retirement.

• Upon retirement (not before age 55 with at least five years of service), you will be eligible for the same cost sharing provisions for retiree medical coverage as those employees not currently eligible for Benefits 2000 (employed prior to January 1996). To facilitate this benefit, upon your retirement, PSEG Power will make a lump sum payment equal to the present value of the normal employer contribution toward health and welfare benefits

	in retirement, as if you were eligible for such benefits as a retiree. You will make the same contributions as those made by a similarly situated employee eligible for such benefits and employer contribution.

A representative of the Human Resources Department from Compensation and Benefits will meet with you at your convenience to explain in more detail the provisions of the above plans. Please call Camille Valvano at 973-430-5879 to arrange this meeting.
