NEES AND EUA TO MERGE IN $634-MILLION TRANSACTION

Industry Restructuring-Driven Consolidation Continues


WESTBOROUGH, Mass., Feb. 1, 1999 _ In the latest consolidation
driven by the restructuring of the region's electricity industry,
New England Electric System (NYSE:NES) and Eastern Utilities
Associates (NYSE:EUA) announced today that they have signed a
merger agreement under which NEES will acquire all outstanding
shares of EUA for $31 per share in cash, subject to upward
adjustment, as described later.  

The merger agreement values the equity of EUA at approximately
$634 million and represents a 23% premium above the price of EUA
shares on Dec. 4, 1998 (the last trading day before other
regional merger announcements affected EUA's share price), and a
5% premium above the closing price on Jan. 29, 1999. 

NEES is New England's second largest electric utility, serving
1.3 million customers through its regulated electric companies in
Massachusetts, Rhode Island and New Hampshire.  The company
announced on Dec. 14, 1998, that it will merge with National Grid
Group plc, the world's largest independent transmission company,
which is based in Coventry, England.  Upon completion of that
merger, NEES will become a wholly owned subsidiary of National
Grid.

The NEES/EUA merger is not contingent upon the NEES/National Grid
merger closing, but has the full support of National Grid,
according to Rick Sergel, president and chief executive officer
of NEES.

EUA is a Boston-based public utility holding company whose
subsidiaries include electric transmission and distribution
utilities in southeastern Massachusetts and northern and south
coastal Rhode Island.  These utilities provide electric service
to approximately 300,000 customers.  

Upon completion of the merger, EUA's operations will be merged
into NEES's. The combined company will serve 1.6 million
electricity customers in 228 New England communities.  The new

company will serve more electricity customers in both
Massachusetts and Rhode Island than any other company. 

NEES and EUA consistently have been the two lowest-cost, major
electric companies in the region.  It is expected that the
geographical fit of the two companies will result in even greater
efficiencies.   The companies expect to file a rate plan with
state regulators in the near future, which will maintain NEES's
low rates, and bring EUA's rates to NEES levels in the future.

"This merger of New England's two most cost-conscious electric
companies is a natural fit in philosophy, geography and corporate
structure," Sergel said.  "Furthermore, it is the first step in
fulfilling the promise of the NEES/National Grid merger."

"EUA and NEES share a long history of providing customers with
high-quality service at low rates.  The synergies between the two
companies will create an even stronger company for our
customers," EUA Chairman and Chief Executive Officer Donald G.
Pardus said.  "Equally important, NEES and EUA customers will
continue to receive the same great service from the same people."

Sergel will be president and chief executive officer of the
combined company upon completion of the merger.  Both Pardus and
EUA President and Chief Operating Officer John R. Stevens have
opted to retire upon the merger's completion.  EUA board members
will be offered positions on the NEES Advisory Board, and Pardus
and Sergel will appoint a transition team representing both
companies.  EUA Executive Vice President Robert G. Powderly will
become president of New England Power Service Company, NEES's
subsidiary that provides administrative and support services to
the other subsidiaries.

"These are the logical steps to take to ensure a smooth
transition as EUA and NEES mesh into a larger, even more
efficient, finely tuned operation," Pardus said.

The combined company will have approximately 250 fewer positions. 
"Our goal is to attain this through voluntary early retirement
and attrition," Sergel said.  NEES will honor EUA's labor
contracts. 

The merger is subject to regulatory approvals by the Securities
and Exchange Commission, Federal Energy Regulatory Commission,
Nuclear Regulatory Commission, and the state utility commissions
in Massachusetts and Rhode Island.  NEES expects to submit all
principal regulatory filings, related both to EUA and National
Grid, this month.  The merger also requires approval by EUA
shareholders.  The merger is expected to be completed by early
2000.

EUA shareholders will receive a cash payment of $31 for each
share held when the merger is completed.  The cash payment will
be subject to an increase of $0.003 per share per day if the
merger is not completed on or before the date following six
months after approval of the merger by EUA shareholders. NEES
will finance the acquisition in part with cash received from the 
sale of its generating business in September 1998.

EUA shareholders will continue to receive dividends at the
current level as declared by the EUA Board of Trustees, until
closing of the merger.

Inc. for EUA.
