                KEYSPAN ENERGY NAME REESTABLISHED

    Brooklyn and Hicksville (September 10, 1998) -- Robert B. Catell, Chairman 
and Chief Executive Officer of MarketSpan Corporation (NYSE:MN), announced that
MarketSpan will begin doing business as KeySpan Energy, effective immediately.

    Over the coming weeks, signs and advertising will be changed to KeySpan
Energy, a name increasingly familiar to energy consumers in the Northeast.  In 
the near future KeySpan Energy will again trade on the New York Stock Exchange 
using the symbol KSE.  Shareholders will vote on a formal name change to KeySpan
Energy at their 1999 Annual Meeting.

    "Through our unregulated subsidiaries, the KeySpan name has continued to 
grow in recognition," said Catell.  "Under the KeySpan banner, we look forward
to fulfilling our promise to build value for our shareholders as we become the
premier energy company in the Northeast."

                 KeySpan Brand Name Established

    The MarketSpan name has been in use for only the three months following the
merger of the Long Island Lighting Company with KeySpan Energy Corporation, the
holding company of Brooklyn Union.  "The change to KeySpan will reestablish a 
name with excellent brand equity and positive recognition among all our 
constituencies," said Catell.  "We want to build on the values that the KeySpan 
name represents."
