          BROOKLYN UNION AND LILCO ANNOUNCE AGREEMENT-IN-PRINCIPLE WITH
                           LONG ISLAND POWER AUTHORITY
          ------------------------------------------------------------

         New York (March 19, 1997) -- The Brooklyn Union Gas Company (NYSE:  BU)
and The Long Island Lighting  Company  (LILCO) (NYSE:  LIL) today announced that
they have reached an agreement-in-principle with the Long Island Power Authority
(LIPA),  under  which LIPA  would  acquire  LILCO's  electric  transmission  and
distribution system, substantially all of its regulatory assets and its share of
the Nine Mile Point 2 nuclear  plant  through a stock  purchase from the holding
company to be formed by Brooklyn Union and LILCO. The holding company, which has
not yet been named,  would include the entire  operations of Brooklyn Union, and
LILCO's natural gas distribution system,  non-nuclear electric generating assets
and certain other assets.

         The  parties   contemplate  that  LIPA  would  acquire  the  stock  for
approximately $2.5 billion in cash. It is anticipated that the purchase of stock
by LIPA will result in proceeds to the combined  company of  approximately  $1.7
billion to $1.9 billion after payment of taxes and other short-term liabilities.
Of the $4.5 billion of LILCO debt  anticipated  to be outstanding at the time of
the closing,  approximately  $3.6 billion will be assumed or refinanced by LIPA,
and the balance will become the  obligation  of the  combined  company or one or
more of its subsidiaries.  It is also currently anticipated that $363 million of
the $702 million of the LILCO preferred  stock  anticipated to be outstanding at
the time of the closing will be exchanged  for  preferred  stock of the combined
company or one of its  subsidiaries,  and the balance  will be redeemed by LIPA.
LIPA  anticipates  financing the transaction  through the issuance of tax-exempt
bonds.

         The  transaction  is  subject  to  negotiation  and  the  signing  of a
definitive  agreement,  and the  approval of the Boards of Directors of Brooklyn
Union and LILCO  and the LIPA  Board of  Trustees.  It is  anticipated  that the
definitive  agreement  will be  subject  to certain  conditions,  including  the
receipt of certain tax rulings and customary regulatory approvals. The companies
noted that they are hopeful that a definitive agreement can be reached, and that
all necessary  approvals  and rulings can be obtained  within 18 months from the
signing of the definitive agreement.

         Dr. William J. Catacosinos, LILCO chairman and chief executive officer,
said,  "This  agreement  achieves our  objective of providing  significant  rate
reductions  for our customers,  while  protecting the interests of our investors
and employees. The new company will be well positioned to take full advantage of
the emerging competitive energy market."

         Mr.  Robert B. Catell,  Brooklyn  Union  chairman  and chief  executive
officer,  said, "The transaction we announced in December between Brooklyn Union
and  LILCO  was a  positive  development  for  customers  and  shareholders.  An
agreement with LIPA, and its  acquisition of LILCO's  regulatory  assets,  would
make the combined  company even stronger and better  positioned for competition.
We will be prepared to provide a true range of competitive  energy  products and
services to customers in New York City and on Long Island."

         Shareholders of Brooklyn Union and LILCO will receive a proxy statement
on the Brooklyn Union/LILCO share exchange,  which was announced on December 29,
1996.  The proxy  statement  will contain  detailed  information  about the LIPA
transaction. The closing of the Brooklyn Union/LILCO share exchange agreement is
not contingent on the consummation of a transaction with LIPA.

         The Brooklyn  Union/LILCO share exchange  agreement  provides that if a
transaction with LIPA, acceptable to Brooklyn Union and LILCO, is completed, the
exchange ratio in the Brooklyn  Union/LILCO share exchange will be adjusted with
the effect that ownership of the LILCO shareholders in the combined company will
increase from  approximately  66% to approximately  68%. The number of shares of
the new company that each share of LILCO will be exchanged for will be increased
from .803 to .880 shares if a LIPA  transaction is consummated.  In either case,
each share of Brooklyn Union will be exchanged for one share of the new company.

         The  agreement-in-principle  provides  that the combined  company would
enter into a Management  Services  Agreement  with LIPA to manage LIPA's assets,
including  its electric  transmission  and  distribution  system,  and to ensure
system  reliability,  including  storm  restoration.  LIPA would  have  ultimate
responsibility,  authority  and  control  over the assets and  operation  of the
transmission  and  distribution  system.  The  initial  term  of the  Management
Services  Agreement  will be eight years.  Thereafter,  the management of LIPA's
assets would be awarded  through a  competitive  bidding  process.  The combined
company agrees to honor existing labor contracts.

         Additionally,  LIPA and the combined  company  would enter into a Power
Supply  Agreement  under which the  combined  company  would supply and manage a
portion of LIPA's power  requirements  for an initial period of 15 years.  Under
the agreement,  LIPA would purchase the  approximately  3,900  megawatts of Long
Island generation  capacity currently owned by LILCO. LIPA would also assume all
existing LILCO contracts for firm power purchases and transmission agreements.

         The Power  Supply  Agreement  will have a capacity  "ramp down"  option
beginning  in  year  seven  in  an  aggregate   potential  reduction  amount  of
approximately  1,500  megawatts.  At the  end of the  initial  15-year  contract
period,  LIPA would have the option of renewing the Power Supply  Agreement  for
all  capacity  upon  which it has not  exercised  its  "ramp  down"  option.  In
addition,  after the third  year,  LIPA will have a one-year  window in which it
could purchase all of the generating assets for fair market value.

         A transaction  under a Brooklyn  Union-LILCO-LIPA  agreement would most
likely be accounted for as a purchase,  as opposed to the  previously  announced
Brooklyn  Union/LILCO share exchange agreement which is intended to be accounted
for as a pooling of interests. Brooklyn Union and LILCO expect to continue their
current dividend policies until a transaction is consummated.

         The Brooklyn Union-LILCO-LIPA  transaction must be approved or reviewed
by various regulatory agencies including:  Public Authorities Control Board, New
York State Public  Service  Commission,  Federal Energy  Regulatory  Commission,
Nuclear Regulatory Commission and the Securities and Exchange Commission.

         With the closing of the transaction,  the Shoreham property tax lawsuit
between LILCO and various taxing  authorities in Suffolk County would be settled
by LIPA and those taxing authorities.

         Brooklyn Union,  with 3,000 employees,  distributes  natural gas to 1.1
million  customers in the New York City  boroughs of Brooklyn and Staten  Island
and in two-thirds of the borough of Queens.  Brooklyn Union's service  territory
covers 187 square miles with a population  of  approximately  4 million  people.
Brooklyn Union has energy-related investments in gas exploration, production and
marketing  domestically and  internationally,  as well as energy services in the
United States, including cogeneration products,  pipeline transportation and gas
storage facilities.

         LILCO's 5,400 employees provide electric and gas service to more than 1
million  customers in Nassau and Suffolk Counties and on the Rockaway  Peninsula
in Queens County.  LILCO's  service  territory  covers 1,230 square miles with a
population of approximately 2.7 million people.

         The Long Island Power  Authority is a corporate  agency of the State of
New York and was created by State legislation enacted in 1986 with the authority
to acquire LILCO. LIPA is governed by a 15 member Board of Trustees. Nine of the
Trustees,  including  the Chairman,  Frank Zarb,  are appointed by the Governor,
three of the Trustees are appointed by the Senate Majority Leader,  and three of
the Trustees are appointed by the Assembly Speaker.

                     TRANSACTION STRUCTURE CONTEMPLATED BY
                           BROOKLYN UNION-LILCO-LIPA

LIPA would  acquire  LILCO's  electric  transmission  and  distribution  system,
     substantially  all of its regulatory  assets and its share of the Nine Mile
     Point 2 nuclear plant  through a stock purchase from the holding company to
     be formed by Brooklyn Union and LILCO. The holding  company,  which has not
     yet been named,  would be  comprised of the entire  operations  of Brooklyn
     Union, and LILCO's natural gas distribution  system,  non-nuclear  electric
     generating assets and certain other assets.

The  combined company would enter into a Management Services Agreement with LIPA
     to  manage  LIPA's  assets,   including  its  electric   transmission   and
     distribution system.

LIPA and the combined  company would enter into a Power Supply  Agreement  under
     which the  combined  company  would  supply  and manage a portion of LIPA's
     power requirements.
