expires on April 1, 2008, and provides for, among other things,  a target annual

calculation of the Employees  Retirement  Plan of KeySpan Energy ("ERP") pension
benefits.  The employment  agreement also provides for certain  special  bonuses
upon successful  completion of certain  transactions,  at the sole discretion of
the Company's board of directors.

Under the employment  agreement,  Mr. Sartor may also be eligible to participate
in the Company's  long-term  incentive  compensation  plan, as well as all other
compensation and benefit plans provided to other senior officers of the Company.
Upon  termination of employment  for any reason other than good cause,  death or
disability,  Mr.  Sartor  will be  entitled  to payment of certain  compensation
accruable through the term of the employment  agreement.  A copy of Mr. Sartor's
employment agreement is attached hereto as Exhibit 10.1.
