RE: LETTER OF UNDERSTANDING REGARDING SEVERANCE BENEFITS

Dear Bill:

This letter reflects NRG Energy, Inc.'s (the "Company") contractual obligation
to you regarding the severance benefits to which you would be entitled in the
event of your termination of employment under the circumstances described
herein. The "Effective Date" of these benefits is April 8, 2003. However, this
is not a contract of employment. You will be classified as an "employee at will"
and your employment will be subject to termination at any time, with or without
cause.

o        In consideration of your continued employment with the Company, your
         execution of this letter agreement, your performance of the obligations
         hereunder, and your execution of a general release of all claims
         against the Company upon to termination of your employment, the Company
         will provide you with severance pay under the following circumstances:
         (i) in the event that the Company involuntarily terminates your
         employment without Cause (as defined below) or (ii) you resign your
         employment with Good Reason (as defined below) after the Effective
         Date, you will receive severance pay in the amount of one and one-half
         times your annual base salary and target bonus 45%. The severance pay
         will be paid in the form of salary continuation or in a single lump sum
         payment (determined in the sole and absolute discretion of the
         Company), in either case, commencing as soon as practicable after your
         termination date. In addition the Company will pay a lump sum for all
         costs associated with your health benefits under COBRA for a period of
         12 months from the effective date of your separation. The employee will
         be responsible for making the COBRA payments to the applicable COBRA
         third party administrator.

o        For purposes of this agreement, the term "Cause" shall mean a
         termination of your employment which is the result of any of the
         following: (i) your felony conviction or your plea of "no contest" to a
         felony; (ii) any fraud by you in connection with the performance of
         your duties as an employee of the Company; (iii) any act of gross
         negligence or gross misconduct by you in the performance of your duties
         as an employee of the Company; (iv) your repeated and continued neglect
         of your duties as an employee of the Company (other than your neglect
         resulting from your incapacity due to a physical or mental illness);
         provided, however, that an event described in item (iv) above shall not
         constitute Cause unless it is communicated by the Company in writing
         thirty (30) days from the date the Chief Executive Officer knows of
         such event and is not corrected by you in a manner which is reasonably
         satisfactory to the Company within thirty (30) days of your receipt of
         such written notice from the Company.

                                                                   March 1, 2003
                                                                          Page 2

o        For purposes of this agreement, "Good Reason" shall mean your
         resignation of your employment as a result of a material and adverse
         change in the scope of your position that results in either: (a) duties
         and responsibilities that are not substantially equivalent to those of
         the position which you currently hold, and that result in a reporting
         relationship below executive senior management, or (b) an assignment
         that requires you to relocate your domicile more than fifty (50) miles
         from your current work location before June 30, 2008; provided,
         however, that a change described above shall not constitute Good Reason
         unless it is communicated by you to the Company in writing thirty (30)
         days from the date you know of such event and is not corrected by
         Company in a manner which is reasonably satisfactory to you within
         thirty (30) days of the Company's receipt of such written notice from
         you.

o        In the event your employment ends at any time as a result of your
         resignation without Good Reason, the Company shall pay you the full
         amount of the accrued but unpaid Salary you have earned through the
         date of your termination, plus a cash payment (calculated on the basis
         of your rate of Salary then in effect) for all unused vacation time
         which you may have accrued as of the date of termination, and any
         unpaid reimbursement for relocation, business or living expenses to
         which you are entitled.

o        You will not be entitled to receive severance benefits if you die,
         retire or become disabled while employed by the Company.

o        Severance payment(s) hereunder shall be an obligation of, and paid by,
         the Company.

o        All of the Company's obligations under this Agreement and your
         Employment letter shall be binding upon the Company. The severance
         benefits specified in this agreement shall be the only severance
         benefits to which you are entitled. The severance benefits specified in
         this agreement replace and supersede any other severance benefit for
         which you previously may have been eligible under any other plan or
         program of the Company or its affiliated companies including, without
         limitation, the NRG Energy, Inc. Involuntary Severance Plan.
         Notwithstanding the foregoing, in the event a bankruptcy court should
         not approve or honor the severance benefits set forth in this
         agreement, the severance benefits for which you were eligible
         immediately prior to this agreement shall be in effect.

o        This agreement and all the terms hereof are confidential. You may not
         disclose, publicize, or discuss any of the terms or conditions hereof
         with anyone, except your spouse, attorney and/or accountant. In the
         event that you disclose this agreement or any of its terms or
         conditions to your spouse, attorney and/or accountant, it shall be your
         duty to advise said individual(s) of the confidential nature of this
         agreement and to direct them not to disclose, publicize, or discuss any
         of the terms or conditions of this agreement with any other person.
         Violation of this confidentiality provision shall result in immediate
         termination of this agreement, loss of all severance benefits and, to
         the extent determined by the Company in its sole and absolute
         discretion, termination of employment for Cause.

RE: LETTER OF UNDERSTANDING REGARDING SEVERANCE BENEFITS

Dear John:

This letter reflects NRG Energy, Inc.'s (the "Company") contractual obligation
to you regarding the severance benefits to which you would be entitled in the
event of your termination of employment under the circumstances described
herein. The "Effective Date" of these benefits is July 23, 2003. However, this
is not a contract of employment. This agreement will require Bankruptcy Court
approval in order to be effective. You will be classified as an "employee at
will" and your employment will be subject to termination at any time, with or
without cause.

-    In consideration of your continued employment with the Company, your
     execution of this letter agreement and your performance of the obligations
     hereunder, the Company will provide you with severance pay under the
     following circumstances: (i) in the event that the Company involuntarily
     terminates your employment without Cause (as defined below) or (ii) you
     resign your employment with Good Reason (as defined below) after the
     Effective Date, you will receive severance pay in the amount of one and
     one-half times your annual base salary (as in effect on your termination
     date). The severance pay will be paid in the form of salary continuation or
     in a single lump sum payment (determined in the sole and absolute
     discretion of the Company), in either case, commencing as soon as
     practicable after your termination date. In addition the Company will pay a
     lump sum for all costs associated with your health benefits under COBRA for
     a period of 12 months from the effective date of your separation. The
     employee will be responsible for making the COBRA payments to the
     applicable COBRA third party administrator.

-    For purposes of this agreement, the term "Cause" shall mean a termination
     of your employment which is the result of any of the following: (i) your
     felony conviction or your plea of "no contest" to a felony; (ii) any fraud
     by you in connection with the performance of your duties as an employee of
     the Company; (iii) any act of gross negligence or gross misconduct by you
     in the performance of your duties as an employee of the Company; (iv) your
     repeated and continued neglect of your duties as an employee of the Company
     (other than your neglect resulting from your incapacity due to a physical
     or mental illness); provided, however, that an event described in item (iv)
     above shall not constitute Cause unless it is communicated by the Company
     in writing thirty (30) days from the date the Chief Executive Officer knows
     of such event and is not corrected by you in a manner which is reasonably
     satisfactory to the Company within thirty (30) days of your receipt of such
     written notice from the Company.

-    For purposes of this agreement, "Good Reason" shall mean your resignation
     of your employment as a result of a material and adverse change in the
     scope of your position that results in (i) duties and responsibilities that
     are not substantially equivalent to those of the position for which you
     were hired and (ii) a reporting relationship below executive senior
     management; provided, however, that a change described above shall not

     within thirty (30) days of the Company's receipt of such written notice
     from you.

-    In the event your employment ends at any time as a result of your
     resignation without Good Reason, the Company shall pay you the full amount

     termination, plus a cash payment (calculated on the basis of your rate of
     Salary then in effect) for all unused vacation time which you may have

-    You will not be entitled to receive severance benefits if you die, retire
     or become disabled while employed by the Company.

-    Severance payment(s) hereunder shall be an obligation of; and paid by, the
     Company.

-    All of the Company's obligations under this Agreement and your Employment
     letter shall be binding upon the Company.

     severance benefit to which you may be entitled under any other plan or
     program of the Company including, without limitation, benefits otherwise
     available under the NRG Energy, Inc. Involuntary Severance Plan.

-    This agreement and all the terms hereof are confidential. You may not
     disclose, publicize, or discuss any of the terms or conditions hereof with
     anyone, except your spouse, attorney and/or accountant. In the event that
     you disclose this agreement or any of its terms or conditions to your
     spouse, attorney and/or accountant, it shall be your duty to advise said
     individual(s) of the confidential nature of this agreement and to direct
     them not to disclose, publicize, or discuss any of the terms or conditions
     of this agreement with any other person. Violation of this confidentiality
     provision shall result in immediate termination of this agreement, loss of
     all severance benefits and, to the extent determined by the Company in its
     sole and absolute discretion, termination of employment for Cause.
