             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. 
  
      Merrill Lynch & Co., Inc. served as financial advisor and delivered a
 fairness opinion to NEES, as did Salomon Smith Barney Inc. for EUA. 
  
      NEES is a public utility holding company headquartered in Westborough,
 Mass.  Massachusetts Electric Company serves 970,000 customers in 146
 communities, and Nantucket Electric Company serves 10,000 customers on the
 island of Nantucket.  Narragansett Electric Company serves 330,000
 customers in 27 Rhode Island communities, and Granite State Electric
 Company serves 36,000 customers in 21 New Hampshire communities.
