EnergyNorth, Inc. Announces Extension of Shareholder Purchase
Rights

Manchester, New Hampshire - May 15, 2000

At its meeting on April 27, 2000, the Board of Directors of
EnergyNorth, Inc. amended the Share Purchase Rights issued to
shareholders under its Shareholder Rights Plan to extend the
exercise period of the Rights for one year. The Rights, which were
set to expire on June 18, 2000, will now expire on June 18, 2001.
The Board acted in light of the Company's previously announced
merger with Eastern Enterprises (NYSE - EI) and KeySpan Energy
(NYSE - KSE), expected to close in the third calendar quarter
of this year.

The Rights will not impede the Eastern/KeySpan mergers; they will
be redeemed by the Company at their redemption price of $0.01 per
share prior to completion of the mergers.
