(a)  The net effect on net  electric  operating  revenues  from  realization  of
     prior-period  mark-to-market  included in line 38 is zero.  Realization  of
     prior-period  mark-to-market relates to cash flow recognition,  not revenue
     recognition.  The arithmetic  opposites of amounts  included in line 33 are
     included in lines 29 and 32. For example, line 33 shows that a prior-period
     mark-to-market  gain of $2 million was  transferred  to "realized"  for the
     total year 2000.  Lines 29 and 32 include  amounts  totaling  $2 million of
     realized revenues for the year 2000.

- ----------
(a)  The net effect on pretax  gross  margin from  realization  of  prior-period
     mark-to-market  included in line 59 and in line 63 is zero.  Realization of
     prior-period mark-to-market relates to cash flow recognition,  not earnings
     recognition.  The arithmetic  opposites of amounts  included in line 55 are
     included  in line 51.  The  opposites  of amounts  included  in line 56 are
     included  in line  53.  For  example,  line 55  shows  that a  prior-period
     mark-to-market  gain of $2 million was  transferred  to "realized"  for the
     total year 2000. A $2 million  realized gain is included in the $69 million
     on line 51 for the total year 2000.
(b)  Quarterly  amounts do not total to the annual amounts because of intra-year
     mark-to-market eliminations.
