Explanation of Responses:
(1)  The option  vests in three equal annual  installments  beginning on May 18,
     2001, except that upon separation of Constellation Energy's merchant energy
     business,  unvested installments will vest and become exercisable on a pro-
     rata  basis  determined  by the  length of time from  5/18/00  to  expected
     separation  date,  and the  option  will  terminate  immediately  prior  to
     separation.
