Exchange rate is CDN$1.5484=US$1.00 (average for 2001).

     1 Emera acquired BHE in October 2001. Consequently, the requests and income
in this row reflect a contribution of only three months of BHE revenues and
income to Emera's consolidated results for 2001.

     2 The Emera consolidated information in this row is pro forma, as if BHE
had been acquired by Emera on January 1, 2001.
