      This Annual Report on Form 10-K contains statements which, to the extent
they are not recitations of historical fact, constitute "forward-looking
statements" within the meaning of the Securities Litigation Reform Act of 1995
("Reform Act"). In this respect, the words "estimate," "project," "anticipate,"
"expect," "intend," "believe" and similar expressions are intended to identify
forward-looking statements. All such forward-looking statements are intended to
be subject to the safe harbor protection provided by the Reform Act. A number of
important factors affecting business and financial results of Long Island
Lighting Company d/b/a LIPA ("LIPA") could cause actual results to differ
materially from those stated in the forward-looking statements. Those factors
include state and federal regulatory rate proceedings, competition and certain
environmental matters each as discussed herein, or in other reports filed by
LIPA with the Securities and Exchange Commission.

Item 1. BUSINESS

      LIPA is a wholly-owned subsidiary of the Long Island Power Authority (the
"Authority"), a corporate municipal instrumentality and a political subdivision
of the State of New York. The Authority's and LIPA's principal offices are
located at 333 Earle Ovington Blvd., Uniondale, New York 11553 and their
telephone number is (516) 222-7700.

      On May 28, 1998, the Authority became the sole stockholder of LILCO (as
defined below) as a result of LIPA Acquisition Corp. (a wholly-owned transitory
subsidiary formed by the Authority to facilitate the acquisition ) merging into
LILCO (the "Merger"). Prior to the Merger, LILCO transferred certain generation
and other assets to a subsidiary company which merged with the former Brooklyn
Union Gas Company to form what was then known as MarketSpan Corporation
("MarketSpan"). MarketSpan has since announced that it will henceforth conduct
its business under the name of KeySpan Energy ("KeySpan"), and that it expects
to formally change its name in 1999. At the time of the Merger, LILCO's
principal assets included: (i) the electric transmission and distribution system
and other items relating to the system that provides electric power and energy
at retail in LIPA's Service Area (as defined herein) (the "T & D System"); (ii)
an 18% undivided ownership interest in Unit 2 of the Nine Mile Point Nuclear
Station ("NMP2"); and (iii) certain agreements and contracts for power supply
and transmission. As used herein, the term "LILCO" means the Long Island
Lighting Company, the publicly-owned gas and electric utility company as it
existed prior to the Merger, and the term "LIPA" means that company as it exists
after the Merger as a wholly-owned electric utility subsidiary company of the
Authority, doing business as LIPA.

Service Area

      The service area in which LIPA conducts its retail electric business
includes two counties on Long Island, Nassau County and Suffolk County (except
for the Nassau County villages of Freeport and Rockville Centre and the Suffolk
County village of Greenport, each of which has its individually owned municipal
electric system), and a small portion of the borough of Queens in New York City
known as the Rockaways (the "Service Area").


                                       3
<PAGE>

      As of December 31, 1998, LIPA had approximately 1.04 million customers in
the Service Area. LIPA receives approximately 49% of its revenue from
residential customers and approximately 48% from commercial and industrial
customers with the balance derived from sales to other utilities and public
authorities. Individual commercial and industrial customers are relatively small
with approximately 45% of these customers having peak demands at less than 75kW.
LIPA's largest customer in the Service Area accounted for less than two percent
of total sales for the nine months ended December 31, 1998.

      In addition to its retail customers, LIPA makes wholesale sales (sales for
resale) to other electric utilities (through the EMA as defined below),
including the three existing municipally-owned electric utilities on Long Island
(the villages of Greenport, Freeport, and Rockville Centre). These villages rely
primarily upon their own generation and purchases from the Power Authority of
the State of New York ("NYPA") for their power supply.

      LIPA also provides electric transmission service to NYPA for the delivery
of NYPA capacity and energy to the three municipal utilities and other
NYPA-power recipients on Long Island, including the Suffolk County Electrical
Agency and the Nassau County Public Utility Agency.

System Operation

      The operation of LIPA's system (including obtaining all necessary power
supplies) is done through operating agreements with various subsidiaries of
KeySpan. Day-to-day operations and maintenance are performed by the workforce of
such subsidiaries. The operating agreements consist of a Management Services
Agreement ("MSA"), a Power Supply Agreement ("PSA") and an Energy Management
Agreement ("EMA").

      The MSA provides for KeySpan Electric Services LLC ("KeySpan Electric") to
perform the day-to-day operation and maintenance of the T&D System, including
among other functions, transmission and distribution facility operation,
customer service, billing and collection, meter reading, planning, engineering
and construction, all in accordance with policies and procedures adopted by the
Authority. Under the MSA, KeySpan Electric earns a management fee and can earn
certain incentive payments or be subject to certain penalties based upon
performance. The term of the MSA is eight years. The PSA provides for the sale
to LIPA by KeySpan Generation LLC of all of the capacity and, to the extent LIPA
requests, energy from the existing oil and gas-fired generation plants on Long
Island formerly owned by LILCO (the "Generating Facilities"). The PSA provides
for incentives and penalties for the maintenance of the output capability of the
Generating Facilities. The term of the PSA is fifteen years. The EMA provides
for KeySpan Energy Trading Services LLC ("KeySpan Energy Trading") to: (i)
procure and manage fuel supplies for LIPA to fuel the Generating Facilities;
(ii) perform off-system capacity and energy purchases on a least-cost basis to
meet LIPA's needs; and (iii) manage off-system sales of output from the
Generating Facilities and other power supplies owned or under contract to LIPA.
The EMA provides for incentives and penalties for performance related to fuel
purchases and off-system power purchases. LIPA is entitled to two-thirds of the
profit from any off-system energy sales arranged by KeySpan Energy Trading. The
term for the services provided in (i) above is fifteen years and the term of the
services provided in (ii) and (iii) above is eight years.

The Transmission and Distribution System

      The T&D System is an integrated transmission and distribution system with
electricity delivered to and from the Service Area over five transmission
interconnections that are owned in part by or are under contract to LIPA. These
interconnections connect the T&D System to utilities outside of the Service Area
and enable delivery of: (i) energy produced by NMP2; (ii) additional energy
resources needed to meet the peak demands of LIPA's electric customers; (iii)
favorably-priced energy to supplement or displace generation from generating
resources within the Service Area; and (iv) excess generation from generating
facilities within the Service Area to purchasers outside of the Service Area
when market conditions merit. The table below provides summary information on
the transmission interconnections.


                                     TABLE 1

(1)   These utilities own the portion of the interconnections not owned by LIPA,
      except for the interconnection with NYPA, which is owned entirely by NYPA.

(2)   CL&P = The Connecticut Light and Power Company.

(3)   Kilovolt or "kV".

      Two of the T&D System's transmission interconnections are tied to the
Consolidated Edison Company of New York, Inc. ("Con Edison") transmission system
in Queens County, New York. LIPA owns these facilities to the border of Nassau
County and Queens County, at which point ownership transfers to Con Edison. The
three remaining interconnections extend under water across the Long Island Sound
to New York or Connecticut. One of these lines, the East Garden City to
Sprainbrook line, is owned entirely by NYPA (the "NYPA Line") and is used by
LIPA under the terms of the contract with NYPA. The other two interconnections
are owned by LIPA from their termination points on Long Island to the middle of
Long Island Sound, at which point ownership is held by the interconnecting
utility.

      The agreement for use of the NYPA Line provides that LIPA will reimburse
NYPA for the costs it incurs in connection with the NYPA Line, including, but
not limited to, debt service, reserves, and operation and maintenance expenses,
in return for the use of the capacity of the line. LIPA is contractually
obligated to pay such costs based on the full capacity of the NYPA Line;
however, to the extent that NYPA allocates capacity to other parties, LIPA's
payment obligations are reduced proportionately, with such other parties making
payments pursuant to rates under NYPA's Open Access Tariff. In the past, NYPA
has allocated capacity of the NYPA Line to certain loads served by NYPA in the
Service Area when there has been insufficient 


                                       5
<PAGE>

capacity to serve such loads on another transmission line jointly owned by LIPA
and Con Edison. This practice is expected to continue in the future.

      LIPA's transmission system includes approximately 1,300 miles of overhead
and underground lines with voltage levels ranging from 345kV to 23kV. There are
32 transmission substations to step down transmission voltage levels from 345kV
or 138kV to 69kV, 33kV or 23kV. The distribution system has approximately 46,000
circuit miles of overhead lines and over 10,000 circuit miles of underground
lines and approximately 149,000 line transformers.

Nine Mile Point Nuclear Power Station, Unit 2

      LIPA owns an 18 percent interest in NMP2, which is part of a two-unit
nuclear power station located at a 900-acre site on Lake Ontario in the Town of
Scriba, New York. NMP2 is rated at 1,144 MW of capacity and is owned by five
co-tenants under a Basic Agreement dated as of September 22, 1975, which
provides for contractual rights, payments and other matters. Under an Operating
Agreement among the co-tenants, dated December 29, 1992, Niagara Mohawk Power
Corporation ("Niagara Mohawk") has the exclusive control of the operation and
maintenance of NMP2 under the oversight of a Management Committee (comprised of
the co-tenants) for policy making, planning, budgeting, and operational
decisions of Niagara Mohawk related to NMP2. This Operating Agreement provides
for a sharing of all costs relating to NMP2 by the co-tenants in proportion to
their percentage interests in the unit.

      NMP2 is scheduled for decommissioning in 2026. LIPA's share of the
decommissioning costs, based on a site specific study conducted in 1995, is
estimated to be $161 million in 1998 dollars ($407 million in 2026 dollars).
LIPA retained title to LILCO's external trust fund established for the
decommissioning of the contaminated portion of the NMP2 plant. The balance in
the external trust fund as of December 31, 1998 was approximately $19 million.
An annual contribution of approximately $3 million is required to fully fund the
external trust fund to meet LIPA's 18 percent share of the costs of
decommissioning the contaminated portion of NMP2 by the decommissioning date of
2026. Commencing in 1999, LIPA will also contribute approximately $1.2 million
annually to fund its share of decommissioning the non-contaminated portion of
NMP2.

      NMP2 has generally exceeded average industry performance for the five
years ended 1997 (the most recent period for which complete information is
reported) with respect to annual capacity factor. Periodic outages for refueling
are being extended to every 24 months rather than every 18 months to improve
overall unit capacity factors. Notwithstanding a 1998 outage described below,
planned and actual outage times have generally decreased due to improved outage
management and fewer emergent problems. The principal factors that caused the
extended outage in 1998 are not expected to recur in future outages.

      NMP2's most recent refueling outage occurred from May 1, 1998 through July
5, 1998. This outage was scheduled to last 35 days, but was extended to 64 days
due, in part, to additional inspections resulting from indications of stress
corrosion cracking of the reactor shroud, a hollow cylinder inside the reactor
vessel that serves to divert cooling water recirculation flow. Niagara Mohawk
reported that the cracking indications were not of any safety significance, and
NMP2 was allowed to resume operations with no particular restrictions. Niagara
Mohawk installed 


                                       6
<PAGE>

appropriate equipment and procedures to manage the problem. Design problems with
the control building heating, ventilating, and air conditioning system, and
delays in reactor pressure vessel disassembly and core off load, among other
factors, caused further delays in the refueling outage. In addition to the
removal of spent fuel assemblies and the installation of new assemblies, Niagara
Mohawk used this refueling outage to perform maintenance and repairs on NMP2.
The next scheduled refueling outage for NMP2 is in 2000.

      Niagara Mohawk has announced that it plans to pursue the sale of its
nuclear assets including its interest in NMP2. LIPA is reviewing its rights and
remedies under the agreements governing its 18% interest in NMP2. LIPA has not
received an offer to purchase its 18% interest in NMP2 and is not pursuing a
sale at this time.

Loads

      The Service Area is characterized by customer usage patterns and weather
conditions that result in peak usage during the summer and relatively low annual
load factors. The peak usage in the summer of 1998 was approximately 4,208 MW.
It is estimated that peak load growth will range between 0.4 percent and 1.3
percent annually on a weather-normalized basis, averaging 0.9 percent over the
1998-2008 period. It is estimated that energy growth will range between 1.0
percent and 1.8 percent annually, averaging 1.3 percent over the 1998-2008
period. This load forecast assumes moderate economic growth in the Service Area,
consistent with the general economic conditions and low levels of unemployment
on Long Island. Residential sales are projected to grow at approximately 1.2
percent per year between 1998 and 2008, while commercial and industrial sales
are expected to grow 1.5 percent per year.

      The load and energy forecasts mentioned above were prepared by KeySpan and
reviewed by LIPA's consulting engineers and take into account a price elasticity
effect resulting from rate reductions that LIPA has implemented. In addition,
these forecasts include the effects of LIPA's conservation program and further
reductions resulting from cogeneration or similar installations designed to
serve customer loads directly.

Power Supply

      LIPA currently expects to rely on existing power supply resources,
additional purchases, and demand side management ("DSM") programs to meet its
capacity and energy requirements during the 1998 through 2008 period. During
1998, LIPA's 18% interest in NMP2 and its rights to the capacity of the
Generating Facilities provided approximately 4,224 MW of generating capacity,
with on-island independent power producers providing an additional 350 MW of
capacity under contract to LIPA. Purchases from NYPA, excluding NYPA's Power for
Jobs Program, and on-island municipal utilities provided approximately 235 MW.
Additional capacity was provided by purchases of 20 MW from NYPA under the Power
for Jobs Program, other firm purchases of 159 MW, and DSM program load
curtailment capability of 17 MW. In aggregate, these resources provided
approximately 5,000 MW in 1998.

      To satisfy the growing needs of its electric customers, LIPA is expected
to enter into additional power purchase agreements beginning on or about June
1999. The estimated power supply plan also anticipates an additional reduction
of approximately 150 MW in customer peak 


                                       7
<PAGE>

load requirements through DSM programs by 2008. As a result of these changes,
total capacity available to LIPA to meet the needs of its customers is expected
to be 5,529 MW by 2008.

Fuel Supply

      Pursuant to the EMA, KeySpan procures and manages the fuel supplies used
at the Generating Facilities. The particular fuel used for generation depends on
generation plant fuel capability, fuel supply, transportation availability, fuel
cost and environmental restrictions. Most of the KeySpan steam units can burn
either natural gas or residual oil and certain units are required to burn lower
sulfur residual oil or natural gas. Natural gas or distillate fuel is burned in
the gas turbines.

      KeySpan shares eight gas delivery interconnections between its
distribution system and the New York gas market. KeySpan and Con Edison have
entered into the New York Facilities Agreement that provides for use of their
joint systems to allow the parties to receive gas from interstate pipelines
connected to their systems.

      Oil is stored on site or at locations accessible by each generation
facility. LIPA believes that: (i) existing oil storage capacity plus an active
oil management program has historically helped avoid a fuel oil supply
disruption at the Generating Facilities; and (ii) conversion of certain
generating units to burn natural gas has further reduced exposure to potential
oil interruptions.

Regulation

      LIPA is subject to regulation by various State and Federal agencies.

      New York State. The Public Service Commission ("PSC") is the principal
agency in the State regulating the generation, transmission, distribution and
sale of electric power and energy. It has no statutory jurisdiction over rates
for power generated, transmitted, distributed or sold by LIPA but does regulate
the rates of New York State's investor-owned utilities and certain municipal
systems to which LIPA sells power.

      The PSC is empowered by the New York Public Service Law to issue
Certificates of Environmental Compatibility and Public Need prior to the
construction in New York of power transmission lines of certain capacities and
lengths, including those of LIPA. In addition, the New York State Board on
Electric Generation Siting and the Environment is empowered by the New York
Public Service Law to issue Certificates of Environmental Compatibility and
Public Need prior to the construction in New York of major electric generating
facilities.

      Under the Long Island Power Authority Act (the "LIPA Act"), the Authority
is empowered to set rates on behalf of LIPA for electric service in the Service
Area without obtaining the approval of the PSC or any other state regulatory
body. See, however, "Management's Discussion and Analysis of Financial Condition
and Results of Operations - Rate Matters."

      The Department of Environmental Conservation ("DEC") is the principal
agency of the State of New York regulating air, water and land quality. Before
any Federal license or permit 


                                       8
<PAGE>

can be issued for any activity involving a discharge into navigable waters, the
DEC must certify that the discharge will comply with the State water quality
standards (or waive certification). Certain aspects of the DEC's regulatory
authority over pollutant discharge permits, air quality permits and hazardous
waste regulation arise from delegation of such authority to the State by Federal
legislation.

      Federal. Under Part II of the Federal Power Act, the Federal Energy
Regulatory Commission ("FERC") regulates the rates, terms and conditions of: (i)
the sale for resale of electric power by "public utilities"; and (ii) the
provision of transmission service in interstate commerce by public utilities.
Neither the Authority nor LIPA is a "public utility" under the Federal Power Act
("FPA"). Although the rates, terms and conditions under which LIPA provides
transmission service are not currently subject to general FERC jurisdiction,
FERC may order LIPA to provide transmission services to individual customers
meeting the requirements of Sections 211 and 212 of the Federal Power Act on
rates, terms and conditions comparable to those of LIPA for LIPA's own use of
its system.

      The Environmental Protection Agency ("EPA") is the principal agency of the
Federal government regulating air, water and land quality. LIPA and the
Authority are subject to EPA rules requiring the securing of routine discharge
permits for non-radiological emissions and effluents from all Authority and LIPA
facilities. The Nuclear Regulatory Commission ("NRC") regulates the construction
and operation of nuclear power plants. The NRC prescribes various operating
standards and other rules for the operation of nuclear power plants.

Shoreham Tax Matters

      Through November 1992, Suffolk County and the following Suffolk County
political subdivisions (collectively, the "Suffolk Taxing Jurisdictions"), the
Town of Brookhaven, Shoreham-Wading River Central School District, Wading River
Fire District and the Shoreham-Wading River Library District (which was
succeeded by the North Shore Library District), levied and received real estate
taxes from LILCO on the Shoreham plant. When the Authority acquired the Shoreham
plant in February 1992, it was obligated pursuant to the LIPA Act to make
Payments-In-Lieu-Of-Taxes ("PILOTs") on the Shoreham plant beginning in December
1992. As part of the agreement between LILCO and the Authority providing for the
transfer of Shoreham to the Authority, LILCO agreed to fund these payments.
Prior to the Merger, LILCO charged rates in an amount sufficient to make these
payments to the Authority. Both LILCO and the Authority contested the
assessments, claiming the Shoreham plant was overassessed. To date, the
Authority has made such payments, in whole or in part, pursuant to interim PILOT
agreements and collected the costs thereof pursuant to the PILOTs rider which is
part of LIPA's rates.

      On March 26, 1997, a judgment was entered in the Supreme Court, State of
New York, Suffolk County, on behalf of LILCO against the Suffolk Taxing
Jurisdictions ordering them to refund to LILCO property tax overpayments
(resulting from over-assessments of Shoreham) in an amount exceeding $868
million, including interest as of the date of the judgment. In addition, the
judgment provides for the payment of post-judgment interest (the "Shoreham
Property Tax Litigation"). The Court also determined that the Shoreham plant had
a value of nearly zero during the period the Authority has owned Shoreham. This
judgment was unanimously affirmed 


                                       9
<PAGE>

by the Appellate Division of the State of New York on July 13, 1998. Certain of
the Suffolk Taxing Jurisdictions sought to appeal this judgment to the New York
State Court of Appeals. Their applications were unanimously denied by the
Appellate Division. New applications for leave to appeal were made to the Court
of Appeals. On January 19, 1999, the Court of Appeals denied the motions. There
is no further review in the New York State court system.

      The Authority had proposed a settlement agreement with the Suffolk Taxing
Jurisdictions and Nassau County. The proposed settlement agreement would, among
other things, cause the Authority: (i) not to enforce the judgment in favor of
LILCO; and (ii) not to make any claim for a refund of what the Authority
believes is an overpayment of PILOTs, in exchange for the payment by the Suffolk
Taxing Jurisdictions to the Authority of $625 million.

      On February 1, 1999, a lawsuit was filed in the Supreme Court of the State
of New York, Nassau County by the Association for a Better Long Island against
the Authority and LIPA. This lawsuit seeks: (i) to require the Authority to
collect the full amount of the judgment obtained by the Authority in the
Shoreham Property Tax Litigation; and (ii) to declare that the offer of the
Authority to settle the Shoreham Property Tax Litigation is void and legally
unenforceable. No assurance can be given as to the method, amount (if any) or
timing of any recovery by the Authority related to the Shoreham Property Tax
Litigation.

      The proposed settlement agreement with the Suffolk Taxing Jurisdictions
was not accepted and on March 1, 1999, the Authority withdrew its offer to
settle the Shoreham Property Tax Litigation including claims related to the
Authority's overpayment of PILOTs on the Shoreham plant for $625 million and
indicated that any settlement would have to be at a higher amount. On that date,
the Authority also demanded that the Suffolk Taxing Jurisdictions pay refunds of
real estate taxes in the amount of approximately $784 million consisting of (i)
refunds and interest due as of the entry of the judgment on March 26, 1997 for
the period from and after January 15, 1987 (the effective date of the LIPA Act)
of approximately $675 million and (ii) accrued post-judgment interest in the
amount of approximately $109 million. Post-judgment interest will continue to
accrue until the judgment is satisfied.

      On September 15, 1998, Suffolk County filed an action against the
Authority in the Supreme Court of the State of New York, County of Suffolk
seeking to enjoin the Authority from recovering tax refunds based upon the
over-assessment of the Shoreham nuclear plant. The action claims that the
Authority does not have the right to recover property taxes previously assessed
against LILCO for tax years 1984-1985 through 1991-1992. On March 19, 1999, the
court ruled that the Authority was not entitled to collect any refund of
property taxes assessed against the Shoreham plant. In addition, the court
stated that the Authority has a duty to discontinue and abandon all proceedings
which seek the repayment of all or part of the taxes assessed against the
Shoreham Plant. The Authority intends to appeal this decision. The Authority
does not believe that an adverse decision in this litigation will have a
material adverse effect on the Authority's or LIPA's financial condition.
Further, the court stated that under a ruling of the New York State Court of
Appeals, the Authority is not prohibited from seeking refunds of PILOTs paid on
over-assessments of the Shoreham plant.

      The New York State Court of Appeals in a separate case has ruled that the
LIPA Act does not prohibit the Authority from seeking refunds plus interest if
it has overpaid PILOTs based on 


                                       10
<PAGE>

an over-assessment of Shoreham. The Authority has made PILOT payments of
approximately $345 million which it believes were based on such an
over-assessment. On February 24, 1999, the Authority filed an action against the
Suffolk Taxing Jurisdictions in the Supreme Court of the State of New York,
Nassau County, seeking a judgment in an amount equal to the total amount of
PILOTs overpaid by the Authority, plus interest.

      On March 23, 1999, the Shoreham Wading River Central School District filed
an action against the Authority in the Supreme Court of the State of New York,
County of Nassau seeking an order directing the Authority to pay approximately
$6.4 million of PILOTs which the plaintiff alleges are due and owing and
approximately $24.6 million of PILOTs which the plaintiff alleges is the
cumulative deficiency as of June 1, 1998. The Authority does not believe that an
adverse decision in this litigation will have a material adverse effect on the
Authority's or LIPA's financial condition.

Certain Factors Affecting the Electric Utility Industry

General

      The electric utility industry has been, and in the future will be,
affected by a number of factors which will have an impact on the business,
affairs and financial condition of both public and private electric utilities,
including the Authority and LIPA.

      One of the most significant of these factors is the efforts on both the
national and local levels to restructure the electric utility industry from a
heavily regulated monopoly to an industry in which there is open competition for
power supply service on both the wholesale and retail level.

      Electric utilities are also subject to increasing Federal, state and local
statutory and regulatory requirements with respect to the siting and licensing
of facilities, safety and security, air and water quality, land use and other
environmental factors. The industry is subject to claims asserting health
effects from electric and magnetic fields associated with power lines, home
appliances and other sources.

Energy Policy Act of 1992

      The Energy Policy Act of 1992 (the "Energy Policy Act") made fundamental
changes in the Federal regulation of the electric utility industry, particularly
in the area of transmission access. The purpose of these changes, in part, was
to bring about increased competition in the wholesale electric power supply
market. In particular, the Energy Policy Act provides FERC with the authority,
upon application by any person selling electricity, federal power marketing
agency, or other power generator, to require a transmitting utility to provide
transmission services to the applicant essentially on a cost-of-service basis.
Municipally-owned electric utilities are "transmitting utilities" for purposes
of these provisions of the Energy Policy Act. However, the Energy Policy Act
specifically denied FERC the authority to mandate "retail wheeling," under which
a retail customer of one utility could obtain transmission services for the
purpose of obtaining power from another utility or non-utility power generator.

FERC Initiatives


                                       11
<PAGE>

      On April 24, 1996, the FERC issued two final rules that contain
significant policy initiatives designed to open the market for generation of
electricity to competition. The final rules effect significant changes in the
regulation of transmission services provided by "public utilities" (as defined
in the FPA) that own, operate or control interstate transmission facilities used
to transmit power in interstate commerce ("jurisdictional utilities"). Neither
the Authority nor LIPA is a jurisdictional utility as so defined.

      One of the final rules, Order No. 888, as modified on rehearing: (i)
requires all public utilities to provide open access transmission services on a
non-discriminatory basis by requiring all such public utilities to file tariffs
that offer other entities seeking use of the interstate transmission system the
same transmission services they provide themselves under comparable terms and
conditions; and (ii) contains a reciprocity provision that requires
non-jurisdictional utilities (including municipal and consumer-owned utilities
such as LIPA and the Authority) that purchase transmission services under
FERC-filed open-access tariffs and that own or control transmission facilities
to, in turn, provide open access service to the transmitting utility on rates,
terms and conditions that are comparable to the service that the
non-jurisdictional utility provides itself. Order No. 888 also includes
provisions which, in effect, would permit jurisdictional utilities to recover
so-called "stranded costs" for generating and other facilities from wholesale
customers of a utility who opt to purchase from other power suppliers.

      The rates that LIPA charges for transmission service under its Open Access
Transmission Tariff ("OATT"), including the calculation of any stranded cost
charge, are not subject to direct regulation by FERC under Part II of the FPA.
FERC has reviewed the rates under LIPA's OATT and found that the OATT represents
an acceptable reciprocity tariff subject to the condition that LIPA adopt a code
of conduct and maintain an Open Access Same-time Information Service ("OASIS").
A prospective customer seeking service under the OATT may challenge the rate or
stranded cost charge quoted by LIPA to the customer by filing an application to
the FERC for an order requiring LIPA to provide transmission service under
Sections 211 and 212 of the FPA. FERC has discretion to entertain such an
application, but it has noted that when FERC has approved an OATT for
comparability purposes for that nonjurisdictional utility the applicant
requesting a Section 211 order has the burden to show why service to the
applicant under the same terms as available under the OATT is not sufficient and
why a Section 211 order should be granted.

      The other final rule, Order No. 889, as supplemented by later orders,
requires standards of conduct for utilities that offer open access transmission
services to ensure that transmission owners and their affiliates do not have an
unfair competitive advantage in using transmission to sell power. To this end,
Order No. 889 (i) requires those utilities to establish an electronic OASIS to
share transmission-related information (including information about available
capacity) on a real-time basis, and also requires those utilities to obtain
information about their transmission systems for their own wholesale power
transactions, such as available capacity, in the same way that their competitors
do via an OASIS; and (ii) promulgated standards of conduct to ensure that
utilities functionally separate their transmission and wholesale power merchant
functions to prevent self-dealing.

      In the Spring of 1997, FERC issued its orders on rehearing of Order Nos.
888 and 889. In these supplemental orders FERC upheld the bulk of its rulings in
Order Nos. 888 and 889, while 


                                       12
<PAGE>

making changes to certain aspects of those rules to implement its open-access
policies. Public utilities were required to submit revised tariffs to FERC
during the Summer of 1997 to reflect FERC's orders on rehearing. In November
1997 and again in 1998, FERC issued further orders on rehearing affirming, with
certain clarifications, its previous orders. Both Order Nos. 888 and 889 have
been appealed to the U.S. Court of Appeals.

      Neither the Authority nor LIPA is directly subject to the new rules.
However, the Authority and LIPA are subject to the reciprocity provision in
Order No. 888, described above. Moreover, the Authority has voluntarily filed an
OATT that substantially conforms to the provisions of Order No. 888, as modified
on rehearing, which FERC had made a condition to FERC's approval of the transfer
to the Authority of LILCO's transmission assets. On September 22, 1998, FERC
approved LIPA's OATT finding that it is consistent with the compatibility
requirements of Order No. 888 as modified on rehearing for an acceptable
reciprocity transmission tariff on the condition that LIPA adopt a code of
conduct and maintain an OASIS. LIPA's OASIS is in place. LIPA has filed its code
of conduct with FERC.

      Under Part 11 of the FPA, "public utilities" are subject to regulation by
FERC. A "public utility" includes any person or entity that owns, controls, or
operates facilities used for the transmission of electric energy in interstate
commerce or for the sale of electric energy at wholesale in interstate commerce.

      However, under Part 11 of the FPA a "public utility" does not include a
state or any political subdivision of a state, or any agency, authority, or
instrumentality of any one or more of the foregoing. As a corporate municipal
instrumentality and political subdivision of the State of New York, the
Authority, and, indirectly, LIPA, are largely exempt from FERC regulation as
"public utilities" under Part H of the FPA. Notwithstanding this exemption, the
Authority and LIPA are subject to the authority of FERC to order interconnection
of its facilities pursuant to Section 210 of the FPA, and the authority of FERC
to order "transmitting utilities" to provide transmission services in accordance
with sections 211 and 212 of the FPA as amended by the Energy Policy Act.

Proposed Federal Deregulation Legislation

      Many bills have been introduced into the United States House of
Representatives and the United States Senate to deregulate the electric utility
industry on the federal or state level, including bills supported by the Clinton
Administration as discussed below. In general, many of the bills provide for
open competition in the furnishing of electricity to all retail customers (i.e.,
retail wheeling). No prediction can be made as to whether these bills, or any
future proposed federal bills to deregulate the electric industry, will become
law, or, if they become law, what their final form or effect would be.

      In March 1998, the Clinton Administration announced a Comprehensive
Electricity Competition Plan. The components of the plan fall into five
categories which include: (i) encouraging states to implement retail competition
by permitting retail customers to purchase power from the supplier of their
choice by January 1, 2003, although it would permit states or non-regulated
utilities to opt out of competition under certain circumstances; (ii) protecting
consumers by facilitating competitive markets; (iii) assuring access to and
reliability of 


                                       13
<PAGE>

transmission systems by amending the Federal Power Act to provide FERC with the
authority to require transmitting utilities to turn over the operational control
of transmission facilities to an independent system operator; (iv) promoting and
preserving public benefits by, among other things, requiring a minimum level of
renewable generation facilities and requiring a trading system for nitrogen
oxide pollutant reductions; and (v) amending federal statutes to provide FERC
with authority to order transmission in certain circumstances, reinforcing FERC
authority over certain matters and amending the laws with respect to tax-exempt
bonds. The Clinton Administration Plan to amend the laws with respect to
tax-exempt bonds would provide that the private use limitations are inapplicable
to outstanding bonds for publicly-owned generation, transmission or distribution
facilities if used in connection with retail competition or open access
transmission. Tax-exempt financing would not be available for new generation or
transmission facilities but would continue to be available for distribution
facilities subject to current law private use limitations.

      Bills were introduced into the Senate and the House in 1998 which
reflected the Clinton Administration's proposal which bills expired upon the
adjournment of the 1998 Congressional session. On February 1, 1999, the Clinton
Administration released its revenue proposals, including proposals that are
substantially the same as those announced in 1998, as described above, which
would impose restrictions on the availability of tax-exempt financing for
electric generation facilities. LIPA can not predict whether the Clinton
Administration will introduce actual legislation to deregulate the electric
utility industry in the current session of Congress and, if so, whether such
legislation will be similar to that which was introduced in 1998. Moreover, LIPA
cannot predict what effect such legislation, if adopted, would have on the
Authority or LIPA.

New York State Electric Utility Industry Restructuring Matters

      Public Service Commission Competitive Opportunities Proceeding. On March
19, 1993, the PSC commenced a proceeding to investigate issues related to a
future regulatory regime for New York's electric industry in light of increasing
competitive opportunities. The second phase of this proceeding, which commenced
in August 1994, concerned issues related to potential restructuring of the
industry from a regulated monopoly service to a more competitive framework.

      The PSC issued an Opinion and Order on May 20, 1996 ("Order 96-12") in the
competitive opportunities proceeding which required each of the New York
investor-owned electric utilities (except Niagara Mohawk and LILCO) to submit a
restructuring plan to the PSC. In Order 96-12, the PSC set goals for the
introduction of competition in New York State's generation and energy services
sectors. The PSC's preferred industry structure would ultimately allow all
customers retail access after a period of transition. The PSC anticipates both
lower electricity prices and economic development to result from competition.

      One of the key issues that must be addressed before competition is
established in New York concerns stranded costs. Stranded (or strandable) costs
are defined by the PSC as those costs incurred by utilities that may become
unrecoverable during the transition from regulation to a competitive market for
electricity. The investor-owned utilities contend that all prudent costs


                                       14
<PAGE>

incurred to provide electric service should be recovered. The PSC stated in
Order 96-12 that the utilities and independent power producers must mitigate
potential stranded costs.

      While not under the regulatory control of the PSC, LIPA has a significant
interest in the outcome of Con Edison, New York State Electric and Gas
Corporation ("NYSEG") and other PSC restructuring proceedings. Any decision by
the PSC relating to the future competitive structure of New York's electric
industry could affect the manner in which LIPA operates.

      Nuclear Plant Issues. In August 1997, the staff of the PSC issued a report
in the context of the PSC's Competitive Opportunities Proceeding proposing,
among other things, that, beyond a transition period, which is generally the
period covered by the individual restructuring agreements before the PSC,
nuclear generation should operate on a competitive basis. The report also
proposed that the sale of nuclear plants to third parties be the preferred means
of determining the fair market value of marketable generation plants, as it
offers the greatest potential for mitigation of stranded costs and for the
elimination of anti-competitive subsidies.

      On March 20, 1998, the PSC initiated a proceeding to examine a number of
issues raised by the staff report and the comments received in response thereto.
In summary, the PSC: (i) adopted as a rebuttable presumption the premise that
nuclear power should be priced on a market basis to the same degree as power
from other sources, with parties challenging that premise having to bear a
substantial burden of persuasion; (ii) characterized the proposals in the staff
report as by and large consistent in concept with the PSC's goal of a
competitive, market-based electricity industry; (iii) questioned the staff's
position that would leave funding and other decommissioning responsibilities
with the sellers of nuclear power interests; and (iv) indicated interest in the
potential for New York Nuclear Operating Company ("NYNOC") to benefit customers
through efficiency gains and directed pursuit of that matter in this nuclear
generation proceeding or separately upon the filing of a formal NYNOC proposal.
The initiating order announced the intention to complete the proceeding by the
second quarter of 1999.

      During 1997, NYPA, Con Edison, Niagara Mohawk and Rochester Gas and
Electric Corporation, the four utilities operating nuclear generating facilities
in New York State, executed a joint announcement which expressed their desire to
move forward with plans to form NYNOC, and stated that the four utilities will
initiate the steps to assure that NYNOC will have the necessary leadership,
personnel and structure to operate the six nuclear units now operated
independently by such utilities. The joint announcement also stated that during
the transition phase, while necessary governmental approvals are sought, the
utilities would continue with and add to the cooperative initiatives the
companies have already begun. NYNOC, a limited liability company, would operate
the six nuclear plants currently operated by the four entities to achieve
economies of scale and increase cost effectiveness. The plants would continue to
be owned, and the output of the plants marketed, by the respective owners of the
plants. It is contemplated that NYNOC would become the operator under the
plants' NRC operating licenses, while other aspects of the NRC licenses would
remain with the owners of the plants. It is uncertain what effect Niagara
Mohawk's participation in such an arrangement will have on LIPA; nor can LIPA
predict the effect on such an arrangement of the auction proposal in the staff
report.

      On or about June 15, 1998, NYSEG, one of the owners of NMP2 commenced an
action against Niagara Mohawk in Supreme Court of the State of New York,
Tompkins County, 


                                       15
<PAGE>

demanding, among other things, judgment to: (i) enjoin Niagara Mohawk from
transferring operating responsibility of NMP2 to NYNOC; and (ii) declare that
Niagara Mohawk may not transfer its operational responsibility for NMP2 to NYNOC
without NYSEG's consent. LIPA can make no prediction as to the outcome of this
litigation.

      The NRC issued a policy statement on the Restructuring and Economic
Deregulation of the Electric Utility Industry ("Policy Statement") in 1997. The
Policy Statement addresses NRC's concerns about the adequacy of decommissioning
funds and about the potential impact on operational safety, and reserves to the
NRC, the right, in highly unusual situations where adequate protection of public
health and safety would be compromised, to consider imposing joint and several
liability on minority co-owners when one or more co-owners have defaulted on
their contractual obligations. On December 28, 1998, the NRC announced
commencement of a rulemaking proceeding initiated by a group of utilities which
are nonoperating joint owners of nuclear plants. These utilities request that
the enforcement provisions of the NRC regulations be amended to clarify NRC
policy regarding the potential liability of joint owners if other joint owners
become financially incapable of bearing their share of the burden for safe
operation or decommissioning of a nuclear power plant. On March 22, 1999, the
Authority filed comments in support of the rule proposed by the group of
utilities. In addition to the above Policy Statement, the NRC is proposing to
amend its regulations on decommissioning funding to reflect conditions expected
from deregulation of the electric power industry. LIPA is unable to predict how
such increased stringency may affect the results of operations or financial
condition of NMP2.

      Independent System Operator Proposal. Pursuant to FERC Order No. 888 as
modified on rehearing, applicable to, among others, the investor-owned electric
utilities (the "IOUs") in New York, which, along with NYPA, comprise the New
York Power Pool ("NYPP"), the IOUs undertook, with NYPA, to develop an
arrangement for providing non-discriminatory open-access transmission over all
of the electric transmission lines in New York. As a result of this effort, the
IOUs and NYPA filed a proposal (as most recently revised, the "Proposal") with
FERC to provide open access to their transmission lines. In addition, the
Proposal would establish the Reliability Council (as defined herein) and the New
York Power Exchange ("NYPE"). The NYPP will be replaced by the independent
system operator ("ISO"), Reliability Council and NYPE. Under the Proposal, the
IOUs and NYPA would form a not-for-profit corporation, the ISO, which would have
responsibility for the operation of most of the transmission lines of the
participants. The ISO would be responsible for scheduling the use of the lines
by its members and others that wished to use the lines for transmission of
electricity, and would be responsible for collecting fees from transmission
customers. Each member and NYPA would retain ownership, and would be responsible
for maintenance, of their respective transmission lines. The customers of the
ISO, including the IOUs and NYPA, would pay fees to the ISO. Any ISO member may
withdraw from the arrangement contemplated by the Proposal, on 90-days' notice
to the board of directors of the ISO but, in the case of an IOU, such withdrawal
requires FERC approval unless the IOU has an "open access" transmission
facilities tariff on file with FERC.

      A significant feature of the ISO's tariff will be its use of a schedule of
flexible transmission rates to take account of the cost of energy at its
destination along the transmission network in meeting competing demands for the
transmission facilities subject to the ISO's jurisdiction.


                                       16
<PAGE>

      Under the Proposal, the IOUs and NYPA would be the first members of the
ISO, and LIPA may join. The Proposal also allows any "Market Participant" (which
would include any person engaged in the wholesale sale, transmission or purchase
of electric energy) to join the ISO by becoming a signatory to the ISO
Agreement. Finally, non-Market Participants (e.g. environmental and consumer
organizations) have the opportunity to participate in the governance of the ISO.
The ISO would be governed by a Board of Directors consisting of the executive
director of the ISO and nine individuals selected by a selection committee
composed of representatives of members, other interested parties and the PSC. No
member of the board of directors will be able to own shares in or have a
continuing business relationship with any Market Participant. The chief
executive officer of the ISO will be chosen by the Board of Directors and will
be responsible for the day-to-day operation of the ISO.

      Pursuant to FERC's June 1998 Order conditionally approving the ISO, the
governance provisions of the ISO are being revised. On October 23, 1998, the
members of the NYPP, including NYPA and the Authority, submitted a settlement
agreement to FERC to modify certain governance provisions in response to FERC's
June 1998 Order. Signatories to the settlement agreement include seventeen
entities other than the members of NYPP (the transmission owners), including the
PSC and representatives of consumer, environmental and other organizations.
Among other things, the proposed agreement modifies the structure of the
management, operations and business issues committees to facilitate a more
diverse representation, reduces the percentage that the votes of the
transmission owners as a group and any individual transmission owner may
constitute of the required vote for adoption of proposals, requires annual
updating of membership on these committees and requires the ISO board to
publicly announce the process for selecting members of these committees. This
proposal must be approved by FERC before it can be implemented.

      The Reliability Council proposed to be established concurrently with the
ISO will be a separate not-for-profit corporation or limited liability company
which will establish safety and reliability standards for all entities,
including the ISO, engaging in electric power transactions on the ISO's
transmission system. An executive committee consisting of thirteen members will
govern the Reliability Council. FERC's June 1998 Order approved the proposed
structure and governance of the Reliability Council.

      Certain members of the ISO have reserved the right to seek a determination
of the United States Internal Revenue Service (the "IRS") that participation in
the arrangement contemplated by the Proposal will not adversely affect the
federal tax-exempt status of any obligations issued by such a member nor
adversely affect its ability to issue future federal tax-exempt obligations.
FERC has conditionally authorized the establishment of the ISO but has not
approved the rates or terms and conditions of service. In December 1998, the
Authority approved LIPA's participation in the ISO provided that certain
modifications are made to the Proposal and approved by FERC which would protect
the tax-exempt status of the Authority's debt in light of LIPA's participation
in the ISO. By order dated January 27, 1999, FERC conditionally accepted, with
modifications, the proposed ISO tariff and the proposed market rules of the ISO
and granted the request for market-based rates. The January 27, 1999 order
called for public hearings on certain aspects of the proposed rates and provided
for settlement judge proceedings.

      Electric utilities are subject to continuing environmental regulation.
Federal, state and local standards and procedures which regulate the
environmental impact of electric utilities are subject to change. These changes
may arise from continuing legislative, regulatory and judicial action regarding
such standards and procedures. No assurance can be given that new standards and
procedures will not be imposed or that existing standards and procedures will
not be changed. An inability to comply with environmental standards could result
in additional capital expenditures to comply, reduced operating levels or the
complete shutdown of individual electric generating units, including NMP2 and
those under contract to LIPA under the PSA, not in compliance. See "Legal
Proceedings - Environmental."

Nuclear Plant Matters

      The Energy Policy Act provides, among other things, that utilities with
nuclear reactors will contribute an aggregate total of $150 million annually,
based upon an assessment, for a period of 15 years, up to a total of $2.25
billion (in 1992 dollars), for the costs for the decommissioning and
decontamination of the DOE nuclear fuel enrichment facilities.

      In accordance with the Nuclear Waste Policy Act of 1982, Niagara Mohawk,
as the operator of Nine Mile Point, in August 1995, entered into a contract with
DOE, under which DOE, commencing not later than January 31, 1998, would accept
and dispose of spent nuclear fuel. However, it appears unlikely that DOE will
accept any spent nuclear fuel from Niagara Mohawk or others before 2010. The
contract provides that Niagara Mohawk will pay quarterly to DOE a fee based on
nuclear generation and sales of electricity from Nine Mile Point at a specified
rate.

      The NRC has adopted decommissioning rules which require reactor operators
to certify that sufficient funds will be available for decommissioning the
contaminated portion of nuclear plants in the form of prepayments or external
sinking funds, either of which must be segregated from the licensee's assets and
outside its administrative control, or by the surety of insurance payable to a
trust established for decommissioning costs. LILCO established such an external
decommissioning trust fund in 1990 to meet these regulatory requirements. LIPA
expects that by the expiration of NMP2's operating license in 2026, there will
be funds in LIPA's decommissioning trust fund sufficient to meet the current
estimated costs for its 18% share of the decommissioning costs of Nine Mile
Point 2. If the estimated NMP2 decommissioning costs should increase, based on
future site specific studies or NRC regulatory changes, LIPA expects to increase
its contributions into the decommissioning trust fund to meet the revised
requirements.

      The Federal Low-Level Radioactive Waste Policy Act, as amended in 1985,
requires states to join compacts or to individually develop their own low-level
radioactive waste disposal site. In response to the Federal law, New York State
had decided to develop its own site because of the large volume of such waste
generated in New York, and had committed to develop a plan for the management of
the low-level radioactive waste in New York State during the interim period
until the disposal facility was available. LIPA cannot predict when such a
facility may be available.


                                       18
<PAGE>

      Niagara Mohawk presently ships the low-level radioactive waste generated
at Nine Mile Point to a disposal facility in Barnwell, South Carolina. During
the period July 1, 1994, to June 30, 1995, the legislature of South Carolina
denied access to the facility to out-of-region low-level radioactive waste
generators, including those in New York State. LIPA cannot predict whether the
Barnwell facility will be closed again to out-of-region low-level radioactive
waste generators at some future date before the New York State disposal facility
becomes available.

      NMP2 has a spent fuel pool ("SFP") to store the spent fuel assemblies
discharged from normal plant operations. The SFP has a total designed capacity
to house 4,049 spent fuel assemblies. There are 1,400 spent fuel assemblies
currently residing in the NMP2 SFP.

      SFP capacity will be reached in the year 2012. Therefore, starting in the
time frame of 2008-2010, the operator of NMP2 is expected to focus on one of the
following options available at that time for the management of its spent fuel:
use of a permanent repository, use of a central interim storage facility
mandated by Congress or the creation and use of additional storage capacity at
Nine Mile Point.

      Niagara Mohawk procures public liability and property insurance for NMP2,
and LIPA reimburses Niagara Mohawk for its 18% share of those costs. The
Price-Anderson Amendments Act mandates that nuclear power plants secure
financial protection in the event of a nuclear accident. This protection must
consist of two levels. The primary level provides liability insurance coverage
of $200 million (the maximum amount available) in the event of a nuclear
accident. If claims exceed that amount, a second level of protection is provided
through a retrospective assessment of all licensed operating reactors.
Currently, this "secondary financial protection" subjects each of the 110
presently licensed nuclear reactors in the United States to a retrospective
assessment of up to $88.1 million for each nuclear incident, payable at a rate
not to exceed $10 million per year. LIPA's interest in NMP2 could expose it to a
maximum potential loss of $15.9 million, per incident, through assessments of
$1.8 million per year in the event of a serious nuclear accident at NMP2 or
another licensed U.S. commercial nuclear reactor. These assessments are subject
to periodic inflation indexing and to a 5% surcharge if funds prove insufficient
to pay claims.

      Niagara Mohawk has also procured $500 million primary nuclear property
insurance with the Nuclear Insurance Pools and approximately $2.3 billion of
additional protection (including decontamination costs) in excess of the primary
layer through Nuclear Electric Insurance Limited ("NEIL"). Each member of NEIL,
including LIPA, is also subject to retrospective premium adjustments in the
event losses exceed accumulated reserves. For its share of NMP2, LIPA could be
assessed up to approximately $1.6 million per loss. This level of insurance is
in excess of the NRC required $1.06 billion of coverage.

      LIPA has obtained insurance coverage from NEIL for the extra expense
incurred in purchasing replacement power during prolonged accidental outages.
Under this program, should losses exceed the accumulated reserves of NEIL, each
member, including LIPA would be liable for its share of deficiency. LIPA's
maximum liability per incident under the replacement power coverage, in the
event of a deficiency, is approximately $700,000.


                                       19

      The NRC has notified all utilities operating nuclear power plants that
they are required to inform the NRC of steps they are taking to see that
computer systems will function properly by the year 2000. In connection
therewith, each such utility was required to submit a written indication of,
among things, whether or not they are pursuing and continuing to pursue a plan
to solve their Year 2000 issue, such as, or similar to, that outlined in the
publication Nuclear Utility Year 2000 Readiness published by the Nuclear Energy
Institute and the Nuclear Utilities Software Management Group (the "NEI/NUSM
Plan"). In addition, not later than July 1, 1999, each such utility must submit
a written response confirming that its plant is Year 2000 ready, or if not
ready, the utility must provide a status report of work remaining to be done.
Niagara Mohawk submitted its required response indicating that it has pursued
and is continuing a Year 2000 readiness program similar to that recommended in
the NEI/NUSM Plan.

Item 2. PROPERTIES

      The location and general character of the principal properties of LIPA are
described in Item 1, "Business" under the headings "The Transmission and
Distribution System" and "Nine Mile Point Nuclear Power Station, Unit 2."

Item 3. LEGAL PROCEEDINGS

      LIPA has been named as a nominal defendant in a derivative suit pending in
the United States District Court for the Eastern District of New York entitled
Sylvester v. Catacosinos, et al. A motion to dismiss on behalf of LIPA was filed
on September 23, 1998 and argued on January 28, 1999. In addition, LIPA has been
named as a defendant in an action brought by the County of Suffolk that is
pending in New York State Supreme Court, Suffolk County, entitled County of
Suffolk v. KeySpan et al. The response date has been postponed until such time
as it is determined whether the action will be consolidated with a consolidated
class action pending in New York State Supreme Court, Nassau County, entitled In
re KeySpan Corporation Shareholder Litigation. Former officers and directors of
LILCO also have been named as defendants in each of these actions.

      The complaints in the foregoing actions allege in substance that certain
former officers of LILCO received excessive compensation which totaled
approximately $67 million in connection with the closing of Brooklyn Union's
merger with LILCO and with the Authority's acquisition of the common stock of
LILCO. The Sylvester lawsuit seeks damages of an unspecified amount. The
complaint brought by the County of Suffolk seeks that the defendants make
restitution, or pay damages, of $67 million.

      Because the cases are in an early state, at which no discovery has yet
taken place, LIPA cannot express an opinion as to the likelihood of any
liability. LIPA has notified KeySpan of its entitlement to indemnification
pursuant to an indemnification agreement dated June 26, 1997, for any losses
LIPA suffers as a result of these lawsuits. LIPA expects that KeySpan will honor
the request for indemnification. LIPA also understands that the Attorney General
of the State of New York is investigating the actions and statements of certain
former officers of LILCO in connection with such compensation.


                                       20

      On September 28, 1998, Suffolk County and the Towns of Huntington and
Babylon (collectively, the "Plaintiffs") brought a class action on behalf of
themselves and all electric utility ratepayers in Suffolk County (the
"Ratepayers") against the Authority, LIPA, KeySpan and others in the United
States District Court for the Eastern District of New York entitled County of
Suffolk et al. v. Long Island Power Authority, et al. (the "Huntington
Lawsuit"). The Huntington Lawsuit alleges, among other things, that: (i) LIPA
and the Authority failed to refund alleged capital gains directly to Ratepayers
as a result of the Merger, unlawfully depriving Ratepayers of their property
under federal and state constitutional provisions; and (ii) LIPA failed to
refund to Ratepayers certain deferred tax reserves carried on LILCO's books at
the time of the Merger, unjustly enriching KeySpan.

      Based on these allegations, Plaintiffs are seeking judgments, among other
things: (i) awarding damages against KeySpan and LIPA for impairment of
contract, breach of contract and conversion; and (ii) declaring that KeySpan
holds the proceeds of the Merger attributable to the capital gains and the
deferred tax reserve in trust for the benefit of the Ratepayers and ordering
KeySpan to make a full accounting of such proceeds. LIPA believes that, although
the recovery sought by Plaintiffs could be material in amount, any such recovery
would not have a material financial impact on LIPA or its Customers.

      In an action commenced on May 26, 1998 (Schulz et al. v. New York State
Public Authorities Control Board et al., United States District Court, Northern
District of New York), plaintiff's complaint, in several claims for relief,
sought a judgment declaring, inter alia, the resolution of the PACB authorizing
the Authority to issue bonds to be null and void on State and federal
constitutional grounds and sought a temporary restraining order or preliminary
injunction prohibiting and enjoining the issuance of bonds. On May 27, 1998, the
District Court denied the plaintiff's request for a temporary restraining order
or preliminary injunction and dismissed the plaintiff's action on the ground
that the plaintiffs lack standing to assert the claims pleaded in the complaint.
On February 8, 1999, the United States Court of Appeals for the Second Circuit
affirmed the District Court's dismissal of the plaintiff's action.

      On May 27, 1998, the Initiative for Competitive Energy (the "ICE") filed
an action in the Supreme Court of the State of New York, County of Suffolk,
against the Authority seeking, inter alia, an injunction enjoining the Authority
from selling bonds "whose purpose is to finance the proposed Shoreham Property
Tax Settlement, the Shoreham Rebates, Credits and Suffolk Surcharge." The action
further requested a judgment declaring invalid and directing the rescission of
the sale of such bonds. By decision dated October 7, 1998, the Supreme Court
dismissed the complaint and ruled in favor of the Authority on all issues. On
October 28, 1998, the ICE filed a notice of appeal.

      In May 1995, eight participants of LILCO's Retirement Income Plan ("RIP")
filed a lawsuit against LILCO, the RIP and Robert X. Kelleher, the Plan
Administrator, in the United States District Court for the Eastern District of
New York. In January 1996, the Court ordered that this action be maintained as a
class action. This proceeding arose in connection with the plaintiffs'
withdrawal, approximately 25 years ago, of contributions made to the RIP,
thereby resulting in a reduction of their pension benefits. On January 7, 1999,
a settlement agreement was filed with the Court providing for the payment of
$7.75 million to the plaintiffs. The Authority would be responsible for
approximately $5.4 million. The settlement is subject to 


                                       21
<PAGE>

judicial review. Amended settlement papers were filed on February 22, 1999 and a
hearing date is scheduled for July 27, 1999.

      In December 1997, Suffolk County brought a suit against the Authority and
others in the Supreme Court of the State of New York County of Nassau seeking a
judgment, among other things: (I) annulling and vacating the acceptance by the
Authority of certain conditions contained in the July 1997 PACB resolution
approving the Authority's acquisition of LILCO and related transactions; (ii)
declaring that all or any actions taken by the Authority to implement or carry
out the PACB conditions are null and void; and (iii) directing that the
Authority take no further action to acquire the stock or assets of LILCO unless
and until such acquisition has been approved by the PACB in the manner approved
by law. A decision was rendered in March 1998 which held for the Authority on
all substantive issues. Suffolk County filed a notice of appeal to the Appellate
Division of the State of New York.

      LIPA is involved in various legal proceedings which are routine litigation
matters incidental to the conduct of its business. In the judgment of the
Authority and LIPA, these matters will not individually or in the aggregate,
have a material adverse effect on the financial position, results of operations
or cash flows of LIPA. See "Business--Shoreham Tax Matters."

Environmental

      In connection with the Merger, KeySpan and LIPA entered into Liabilities
Undertaking and Indemnification Agreements which, when taken together, provide,
generally, that environmental liabilities will be divided between KeySpan and
LIPA on the basis of whether they relate to assets transferred to KeySpan or
retained by LIPA as part of the Merger. In addition, to clarify and supplement
these agreements, KeySpan and LIPA also entered into an agreement to allocate
between them certain liabilities, including environmental liabilities, arising
from events occurring prior to the Merger and relating to the business and
operations to be conducted by LIPA after the Merger (the "Retained Business")
and to the business and operations to be conducted by KeySpan after the Merger
(the "Transferred Business").

      KeySpan is responsible for all liabilities arising from all manufactured
gas plant operations ("MGP Sites"), including those currently or formerly
operated by KeySpan or any of its predecessors, whether or not such MGP Sites
related to the Transferred Business or the Retained Business. In addition,
KeySpan is liable for all environmental liabilities traceable to the Transferred
Business and certain scheduled environmental liabilities. Environmental
liabilities that arise from the non-nuclear generating business may be
recoverable by KeySpan as part of the capacity charge under the PSA. LIPA is
responsible for all environmental liabilities traceable to the Retained Business
and certain scheduled environmental liabilities.

      Environmental liabilities that exist as of the date of the Merger that are
untraceable, including untraceable liabilities that arise out of common and/or
shared services have been allocated 53.6% to LIPA and 46.4% to KeySpan.

Environmental Matters Retained by LIPA

      Long Island Sound Transmission Cables. The Connecticut Department of
Environmental Protection ("DEP") and the DEC separately have issued
Administrative Consent Orders ("ACOs") in connection with releases of insulating
fluid from an electric transmission cable system located under the Long Island
Sound. The ACOs require the submission of a series of 


                                       22
<PAGE>

reports and studies describing cable system condition, operation and repair
practices, alternatives for cable improvements or replacement, and environmental
impacts associated with prior leaks of fluid into the Long Island Sound.
Compliance activities associated with the ACOs are ongoing.

      Simazine. Simazine is a commercially available herbicide manufactured by
Novartis that was used by LILCO as a defoliant until 1993 under the direction of
a New York State Certified Pesticide Applicator. Simazine contamination was
found in groundwater at one of the LIPA substations in 1997. LIPA is working
cooperatively with the Suffolk County Department of Health, the DEC and Novartis
to conduct studies and monitoring activities in connection with the presence of
this herbicide.

      Superfund Sites.

      Under Section 107(a) of the federal Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA", also commonly referred to as the
"Superfund Legislation"), parties who generated or arranged for disposal of
hazardous substances are liable for costs incurred by the EPA in responding to a
release or threat of release of the hazardous substances.

      Metal Bank. In December 1997, the EPA issued its Record of Decision
("ROD"), in connection with the remediation of a licensed disposal site located
in Philadelphia, Pennsylvania, and operated by Metal Bank of America. In the
ROD, the EPA estimated that the present worth cost of the selected remedy for
the site is $17.3 million. In June 1998, the EPA issued a unilateral
administrative order to 13 PRPs, including LIPA, for the remedial design and for
remedial action at the site. LIPA can not predict with reasonable certainty the
actual cost of the selected remedy, who will implement the remedy, or the cost,
if any, to LIPA. Under a PRP participation agreement, LIPA is responsible for
7.95% of the costs associated with implementing the remedy. LIPA has recorded a
liability of $1.6 million representing its estimated share of the additional
cost to remediate this site.

      PCB Treatment Inc. LILCO has also been named a PRP for disposal sites in
Kansas City, Kansas and Kansas City, Missouri. The two sites were used by a
company named PCB Treatment, Inc. from 1982 until 1987 for the storage,
processing, and treatment of electric equipment, oils and other materials
containing PCBs. According to the EPA, the buildings and certain soil areas
outside the buildings are contaminated with PCBs. Certain of the PRPs, including
LILCO and several other utilities, formed a group, signed a consent order, and
have developed a work plan for investigating environmental conditions at the
site. The EPA provided LILCO with documents indicating that LILCO was
responsible for less than 1% of the materials that were shipped to this site.
LIPA is currently unable to determine its share of the cost to remediate these
sites.

Environmental Matters Which May Be Recoverable From LIPA By KeySpan Through The
PSA

      Asharoken. In March 1996, the Village of Asharoken (the "Village") filed a
lawsuit against LILCO in the New York Supreme Court, Suffolk County
(Incorporated Village of Asharoken, New York, et al. V. Long Island Lighting
Company). The Village is seeking 


                                       23
<PAGE>

monetary damages and injunctive relief based upon theories of negligence, gross
negligence and nuisance in connection with the LILCO design and construction of
the Northport Power Plant which the Village alleges upset the littoral drift,
thereby causing beach erosion. In November 1996, the court decided LILCO's
motion to dismiss the lawsuit, dismissing two of the three causes of action. The
court limited monetary damages on the surviving continuous nuisance claim to
three years prior to the commencement of the action. The liability, if any,
resulting from this proceeding cannot yet be determined. However, LIPA does not
believe that this proceeding will have a material adverse effect on its
financial position, cash flows or results of operations.

Environmental Matters Which Are Currently Untraceable For Which LIPA Could Have
Responsibility

      Other Superfund Sites. In connection with a lawsuit filed against LILCO
and nine other PRPs by the Town of Oyster Bay for indemnification for
remediation and investigation costs for a federal Superfund site in Syosset, New
York, a settlement agreement has been reached and is subject to court approval.
If approved, the settlement would not have a material adverse effect on LIPA's
financial position, cash flows or results of operations. In addition, LILCO was
notified by the Attorney General of the State of New York that it may be
responsible for the disposal of wastes and/or for the generation of hazardous
substances that may have been disposed of at the Blydenburgh Superfund site.
LILCO conducted a search of its corporate records and did not locate any
documents concerning waste disposal practices associated with this landfill.
Based on current information, LIPA does not believe that this proceeding will
have a material adverse effect on its financial position, cash flows or results
of operations.

      DEC has notified LILCO, pursuant to the New York State superfund program,
that LIPA may be responsible for the disposal of hazardous substances at the
Huntington/East Northport Site, a municipal landfill property. The DEC
investigation is in its preliminary stages, and LIPA is currently unable to
determine its share, if any, of the costs to investigate and remediate this
site.

Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

      On October 12, 1998, LIPA commenced a tender offer for its 7.30%
Debentures Due 2000, 6.25% Debentures Due 2001, 7.05% Debentures Due 2003, 7.00%
Debentures Due 2004, 7.125% Debentures Due 2005 and 9.00% Debentures Due 2022
(collectively, the "Debentures").

      In conjunction with the tender offers, LIPA also commenced a consent
solicitation from the holders of the Debentures to effect an amendment to the
indentures under which the Debentures were issued. The amendment deletes an
inoperative provision in the indentures. The tender of a Debenture constituted a
consent. As of October 26, 1998, the requisite consents for the amendment to the
indentures were received. For each series of Debentures the following table
lists as of November 9, 1998, 5:00 p.m., New York City time, the expiration date
of the tender offer, the principal amount validly tendered pursuant to the
tender offer and the principal amount remaining outstanding on such date:

Item 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

On May 28, 1998, LIPA Acquisition Corp., a wholly-owned subsidiary of the
Authority, was merged with and into LILCO, pursuant to an Agreement and Plan of
Merger dated as of June 26, 1997 by and among LILCO, MarketSpan Corporation
(formerly known as BL Holding Corp., and currently known as KeySpan Energy
"KeySpan"), the Authority and LIPA Acquisition Corp., (the "Merger Agreement").
As a result of the Merger, there was a change in control of LILCO which
effectively resulted in the creation of a new reporting entity, LIPA. See Note 2
of Notes to Financial Statements. Accordingly, the accompanying financial
statements for the periods prior to and including May 28, 1998 are not
comparable to the financial statements presented subsequent to May 28, 1998.
Therefore, a black line has been drawn on the accompanying financial statements
to distinguish between LIPA and LILCO balances and activity.

The amounts presented in the financial statements for LILCO reflect the
presentation of the gas business (as transferred to a KeySpan subsidiary
pursuant to the Merger Agreement) as a discontinued operation, in accordance
with the provisions of Accounting Principles Board ("APB") Statement No. 30.

On April 11, 1997, LILCO changed its year-end from December 31 to March 31.
Subsequent to the Merger, LIPA adopted a calendar year-end. Accordingly, unless
otherwise indicated, references to December 1998 and December 1997 represent the
nine month periods ended December 31, 1998 and December 31, 1997, respectively.
References to March 31, 1998 and March 31, 1997 represent the twelve-month
periods then ended, while references to all other periods refer to the
respective calendar years ended December 31.

Effective May 29, 1998, LIPA  contracted with KeySpan to provide  operations and
management  services to LIPA's  transmission and distribution system through the
MSA.  LIPA  contracts for capacity  from the fossil fired  generating  plants of
KeySpan through the PSA. Energy is purchased by KeySpan on LIPA's behalf through
the EMA. See "Business - System Operation."

The following table combines the condensed results of operations of both LIPA
and LILCO in order to facilitate comparison of the nine months ended December
31, 1998 and 1997.

</TABLE>

The table highlights the effects of the Merger, which include lower electric
revenues as a result of LIPA's rate reduction (approximately 20% for all
customers effective May 29, 1998).


                                       26
<PAGE>

As LIPA is a wholly owned subsidiary of the Authority and not an investor owned
utility, the PSC does not have jurisdiction with respect to the determination of
rates and charges. See, however, Note 4 of Notes to the Financial Statements.
Rates and charges for LIPA are determined by the Authority's Board of Trustees.

The excess of the acquisition cost over the fair value of the net assets
acquired has been recorded as an intangible asset titled "acquisition
adjustment" and is being amortized over a 35 year period, the weighted average
useful life of the net plant assets acquired. The acquisition adjustment
principally arose through the eliminaiton of LILCO's regulatory assets and
liabilities, totaling $6.3 billion, and net deferred Federal income tax
liability of approximately $2.4 billion. Therefore, the amortization of the
regulatory assets and liabilities has effectively been replaced by the
amortization of the acquisition adjustment. Because of the tax exempt status of
LIPA, the results of operations for the period May 29, 1998 to December 31,
1998, do not include a provision for income taxes.

Results of Operations

Earnings

Earnings for the nine month period ended December 31, 1998 and the nine month
period ended December 31, 1997 were as follows:

Net losses for the period beginning May 29, 1998 and ending December 31, 1998
were $80 million. The loss was principally due to customer rebates of $168.8
million paid by LIPA. Earnings per share for the period May 29, 1998 to December
31, 1998 is not meaningful due to the significant change in the capital
structure as a result of the Merger and because no public equity of LIPA is
outstanding as of December 31, 1998.

Net losses for the period beginning April 1, 1998 and ending May 28, 1998 were
$9.4 million or $0.08 per common share. Earnings for common stock for the nine
months ended December 31, 1997, were $207.4 million or $1.71 per common share.
The results for the two month period ended May 28, 1998 were negatively impacted
by Merger-related expenses such as legal, accounting, financial and tax
consultants, certain severance payments made to LILCO officers, and Federal
income taxes resulting from the Merger. These items were partially offset by the
positive impact on earnings caused by the change in method of amortizing the
Rate Moderation Component ("RMC"), as discussed below.

Earnings for the years ended March 31, 1998 and March 31, 1997 were as follows:

For the year ended March 31, 1998, LILCO had higher earnings in the electric
business partially offset by lower earnings in the gas business, as compared to
the prior year.

The increase in earnings for the year ended March 31, 1998, was primarily due to
a change in the method of amortizing the RMC to eliminate the effects of
seasonality on monthly operating income, as more fully discussed in the section
titled "Rate Moderation Component." This positive contributor to earnings more
than offset the effects of reduced interest income and the accruals for certain
obligations for key employees, as more fully discussed in Note 3 of Notes to
Financial Statements.

The decrease in earnings in the gas business for the year ended March 31, 1998
resulted primarily from the accruals noted above, partially offset by lower
operations and maintenance expenses.

Earnings  for the years ended  December  31, 1996 and  December 31, 1995 were as
follows:

LILCO's 1996 earnings were higher for both its electric and gas businesses, as
compared to 1995, despite an allowed return on common equity in 1996 equal to
the prior year. The higher earnings were the result of LILCO's increased
investment in electric plant in 1996, as compared to 1995. Also contributing to
the increase in electric business earnings was LILCO's ability to reduce
operations and maintenance expenses and the efficient use of cash generated by
operations to retire maturing debt.

The increase in earnings in the gas business was the result of additional
revenues due to the continued growth in the number of gas space heating
customers. Also contributing to the increase in gas business earnings was a 3.2%
rate increase which became effective December 1, 1995, and an increase in
off-system gas sales.

Nine Months Ended December 31, 1998 and 1997

Revenues decreased approximately $215 million during the nine month period ended
December 31, 1998, compared to the similar period in 1997. The decrease in
revenue is principally the result of the rate reduction (of approximately 20%),
for all customers, effective May 29, 1998. The increase in sales volume, is
attributable to the rate reduction (reflecting the price elasticity of demand),
the effects of weather (as cooling degree days during the summer months of 1998
were greater than 1997 levels), combined with the addition of new customers.

Years Ended March 31, 1998 and 1997

The slight increase in revenues for the year ended March 31, 1998, when compared
to the year ended March 31, 1997, was primarily due to higher system sales
volumes resulting in part from the addition of approximately 8,000 new electric
customers and higher fuel expense recoveries, partially offset by lower sales to
other utilities.

Years Ended December 31, 1996 and 1995

Revenue decreased approximately $18 million during the 12-month period ended
December 31, 1996, when compared to the similar period in 1995. This decrease is
primarily the result of weather, as the summer cooling season of 1996 included
fewer cooling degree days than that of 1995. It should be noted, however, that
LILCO experienced a growth in electric system sales in 1996 on a
weather-normalized basis compared to 1995. This growth was primarily
attributable to the addition of new electric customers.

Variations in fuel and purchased power expenses have a minimal impact on
operating results as LIPA's current rate structure includes a mechanism (the
FPPCA mechanism) which provides LIPA with the ability to collect from its
customers, and requires LIPA to return to its customers, actual fuel costs which
fall outside of the fuel cost tolerance band, which is defined as 1% higher and
1% lower than the base cost of fuel collected through rates. These percentages
increase to two percent in 2000 and continue to increase in one percent
increments thereafter.

Nine Months Ended December 31, 1998 and 1997

Fuel expense for the nine month period ended December 31, 1998 increased
approximately $8 million, when compared to the similar period of 1997,
principally as a result of the recognition of an expense associated with the
FPPCA mechanism, which totaled approximately $22 million, thereby matching fuel
expense with fuel revenue. A corresponding liability was recorded to recognize
these overcollections. Fuel expense incurred to generate and or purchase
electric energy decreased approximately $14 million (exclusive of the FPPCA
mechanism adjustment), despite a 5% increase in energy requirements. This
decrease is primarily attributable to decreasing oil prices and slightly lower
gas prices partially offset by the fees paid to KeySpan by LIPA under the EMA.
Under this agreement, KeySpan is required to deliver the most economical energy
available, whether that energy comes from generation owned by KeySpan or
purchased from others.

Years Ended March 31, 1998 and 1997

Fuel costs increased as a result of higher system sales volumes. During 1998,
the price per kilowatt hours ("kWh") of power purchased increased over 1997. As
a result, LILCO changed the mix of generation and purchased power in 1998, when
compared to 1997, by generating more electricity using gas and oil rather than
purchasing the equivalent energy off-system.

Years Ended December 31, 1996 and 1995

Despite a slight decrease in energy requirements, fuel expense increased as a
result of a sharp increase in the cost of natural gas and an increase in the per
unit cost of purchased power. LILCO increased generation with oil to minimize
the impact of increasing gas prices on generation costs.

Operations and Maintenance Expenses

Nine Months Ended December 31, 1998 and 1997

Operations and Maintenance ("O&M") expenses, excluding fuel and purchased power,
were $467 million and $304 million for the nine month periods ended December 31,
1998 and 1997, respectively. The increase is primarily due to the manner in
which LILCO classified certain expenses such as depreciation and amortization,
property taxes and other operating taxes. These costs are incurred by LIPA as
part of the costs of contracts with KeySpan for the management of LIPA's assets
and are classified as O&M expense by LIPA. These expenses were separately
reported by LILCO. In addition, there were charges incurred by LIPA related to
the overhead expenses of the Authority, and charges incurred by LILCO for
certain employee benefit expenses, including non-officer incentives and
previously deferred vacation accruals, which were recognized during the period
April 1, 1998 through May 28, 1998.

Years Ended March 31, 1998 and 1997

O&M expenses, excluding fuel and purchased power, were $404 million and $376
million, for the years ended March 31, 1998 and 1997, respectively. This
increase in O&M was primarily due to the recognition of higher performance-based
employee incentives and certain other charges for employee benefits related to
the Merger.

Years Ended December 31, 1996 and 1995

O&M expenses, excluding fuel and purchased power, were $386 million and $399
million, for the years ended December 31, 1996 and 1995, respectively. This
decrease in O&M was primarily due to LILCO's cost containment program which
resulted in lower plant maintenance, distribution and administrative and general
expenses.

Rate Moderation Component ("RMC")

The RMC represented the difference between LILCO's revenue requirements under
conventional ratemaking and the revenues provided under LILCO's electric rate
structure. In addition, the RMC was adjusted for the operation of LILCO's Fuel
Moderation Component ("FMC") mechanism and the difference between LILCO's share
of actual operating costs at Nine Mile Point Nuclear Power Station, Unit 2
("NMP2") and amounts provided for in electric rates.

In April 1998, the PSC authorized a revision to LILCO's method for recording its
monthly RMC amortization. Prior to this revision, the amortization of the annual
level of RMC was recorded monthly on a straight-line, levelized basis over
LILCO's rate year which ran from December 1 to November 30. However, revenue
requirements fluctuated from month to month based upon consumption, which is
greatly impacted by the effects of weather. Under the revised method, effective
December 1, 1997, the monthly amortization of the annual RMC level varied based
upon each month's forecasted revenue requirements, which more closely aligned
such amortization with LILCO's cost of service. As a result of this change, for
the fiscal year ended March 31, 1998, LILCO recorded approximately $65.1 million
more of non-cash RMC credits to income (representing accretion of the RMC
balance), or $42.5 million net of tax, representing $.35 per share more than it
would have under the previous method.

<PAGE>

Nine Months Ended December 31, 1998 and 1997

As mentioned above, adjustments were made on May 29, 1998 to eliminate all
regulatory assets and liabilities from the balance sheet; accordingly, the
results of operations for the nine months ended December 31, 1998 include only
amortization for the period April 1, 1998 through May 28, 1998.

Years Ended March 31, 1998 and 1997

For the years ended March 31, 1998 and March 31, 1997, LILCO recorded non-cash
credits to income of approximately $52 million and $30 million, respectively,
representing the amount by which its revenue requirements exceeded revenues
provided for under the electric rate structure then in effect. Partially
offsetting these accretions was the effect of the FMC mechanism and the
difference between actual NMP2 costs and the amounts provided for in electric
rates. The adjustments to the accretion of the RMC totaled $17 million and $27
million, respectively, of which $12 million and $23 million, respectively, were
derived from the operation of the FMC mechanism.

Years Ended December 31, 1996 and 1995

For the year ended December 31, 1996, LILCO recorded a non-cash credit to income
of approximately $50 million, representing the amount by which revenue
requirements exceeded revenues provided for under the electric rate structure
then in effect. Partially offsetting this accretion were the effects of the FMC
mechanism and the difference between actual NMP2 costs and the amounts provided
for in electric rates. The adjustments to the accretion of the RMC totaled $26
million, of which $24 million was derived from the operation of the FMC
mechanism.

For the year ended December 31, 1995, LILCO recorded a non-cash charge to income
of approximately $22 million, after giving effect to the credits generated
principally by the operation of the FMC mechanism.

For a further discussion of the RMC, see Note 3 of Notes to Financial
Statements.

Other Regulatory Amortization

The significant components of LILCO's other regulatory amortization were as
follows:

Net Margin - An electric business unit revenue reconciliation mechanism,
established under the LRPP (as discussed below), which eliminated the impact on
earnings of sales that were above or below those amounts provided in electric
rates by providing a fixed annual net margin level (defined as sales revenue,
net of fuel and gross receipts taxes). Variations in electric revenue resulting
from the differences between the actual net margin sales levels and those
provided for in rates were deferred on a monthly basis during the rate year
through a charge or credit to other regulatory amortization. These deferrals
were then refunded to or recovered from customers as explained below under "LRPP
Amortization."

LRPP Amortization - Under LILCO Ratemaking and Performance Plan ("LRPP"),
deferred balances resulting from the net margin, electric property tax expense
reconciliation, earned performance incentives, and associated carrying charges
were accumulated during each rate year. The first $15 million of the total
deferral was recovered from or credited to electric customers by increasing or
decreasing the RMC balance. Amounts deferred in excess of $15 million, upon
approval by the PSC, were refunded to or recovered from customers through the
Fuel Cost Adjustment ("FCA") mechanism over a subsequent 12-month period, with
the offset being recorded in other regulatory amortization.

For the rate years ended November 30, 1997 and 1996, the total amount deferred
under the LRPP was $4.0 and $15.0 million, respectively. Such amounts were
credited against the RMC balance.

Nine Months Ended December 31, 1998 and 1997

As mentioned above, adjustments were made on May 29, 1998 to eliminate all
regulatory assets and liabilities from the balance sheet; accordingly, the
results of operations for the nine months ended December 31, 1998 include only
amortization for the period April 1, 1998 through May 28, 1998.

Years Ended March 31, 1998 and 1997

For the year ended March 31, 1998, there was no LRPP amortization, as LILCO had
not received approval from the PSC to begin refunding $26 million of the
remaining deferred LRPP balance in excess of $15 million for the rate year ended
November 30, 1995. For the year ended March 31, 1997, LILCO recognized $42.4
million of non-cash charges to income representing the amortization of the
deferred LRPP balance related to the rate year ended November 30, 1994.

Years Ended December 31, 1996 and 1995

For the year ended December 31, 1996, LILCO recognized $58.7 million of non-cash
charges to income representing the amortization of the deferred LRPP balance
related to the rate year ended November 30, 1994.

For the year ended December 31, 1995, LILCO recognized $52.9 million of non-cash
charges to income representing the amortization of the deferred LRPP balance
related to the rate year ended November 30, 1993.

For a further discussion of the LRPP, see Note 3 of Notes to Financial
Statements.

Excess Earnings - Also recorded in other regulatory amortization, if applicable,
were non-cash charges representing: (a) 100% of electric earnings generated by
LILCO in excess of amounts provided for in electric rates, which was returned to
electric customers through a reduction to the RMC balance; and (b) 50% of the
gas earnings generated by LILCO in excess of amounts provided for in gas rates,
which was returned to firm gas customers. Effective February 5, 1998, LILCO, in
accordance with PSC guidelines, established a gas balancing account in order to
defer excess gas earnings for future disposition. For the 


                                       34
<PAGE>

rate year ended November 30, 1997, the electric business earned $4.8 million in
excess of its allowed return on common equity and the firm gas customers'
portion of the gas business earnings was $6.3 million.

Shoreham Post Settlement Costs - Represented the amortization of Shoreham
decommissioning costs, fuel disposal costs, PILOT's, carrying charges and other
costs over a forty-year period on a straight line remaining life basis.

Nine Months Ended December 31, 1998 and 1997

As previously indicated, adjustments were made on May 29, 1998 to eliminate all
regulatory assets and liabilities on the balance sheet; accordingly, the results
of operations for the nine months ended December 31, 1998 only include
amortization for the period April 1, 1998 through May 28, 1998.

Years Ended March 31. 1998 and 1997

Other regulatory amortization was a non-cash charge to income of $36 million and
$96 million for the years ended March 31, 1998 and 1997, respectively. For the
year ended March 31, 1997, LILCO recognized approximately $42 million of charges
representing the amortization of the deferred LRPP balance associated with the
rate year ended November 30, 1994. For the year ended March 31, 1998, there was
no LRPP amortization, as LILCO had not received approval from the PSC to begin
refunding $26 million of the remaining deferred LRPP balance in excess of $15
million for the rate year ended November 30, 1995. Also contributing to the
decrease in other regulatory amortization was the timing of the recognition of
electric excess earnings for the rate years ended November 30, 1997 and 1996.

Years Ended December 31, 1996 and 1995

Other regulatory amortization was a non-cash charge to income of $110 million
and $156 million for the years ended December 31, 1996 and 1995, respectively.
This decrease is primarily attributable to the operation of the net margin
discussed above. For the year ended December 31, 1995, the amount deferred
related to the net margin amounted to $64 million compared to $3 million for the
year ended December 31, 1996.

Depreciation and Amortization

Nine Months Ended December 31, 1998 and 1997

Depreciation and amortization expense increased approximately $47 million for
the nine month period ended December 31, 1998, when compared to the similar
period of the prior year, primarily due to the amortization of the acquisition
adjustment totaling approximately $10 million per month beginning June 1998.
This increase was partially offset by the absence of depreciation expense on
LILCO's non-nuclear generating assets which is included in O&M, as a component
of the PSA billings.

Operating Taxes

Nine Months Ended December 31, 1998 and 1997

Operating taxes were $218 million and $296 million for the nine month periods
ended December 31, 1998 and 1997, respectively. The decrease is principally the
result of the absence of property and payroll taxes related to the operation of
the non-nuclear generating facilities of LILCO and reduced revenue taxes 


                                       35
<PAGE>

(due to lower revenues), partially offset by PILOTS on the Shoreham Nuclear
Power Station (LILCO was able to capitalize these PILOTS under its electric rate
structure).

Years Ended December 31, 1996 and 1995

Operating taxes were $390 million and $375 million for the years ended December
31, 1996 and 1995, respectively. The increase in 1996, as compared to 1995, is
primarily related to higher property taxes.

Customer Rebates

Nine Months Ended December 31, 1998 and 1997

During the period May 29, 1998 to December 31, 1998, LIPA paid customer rebates
of $169 million relating to Shoreham property tax over assessments (for a
further discussion see Note 13 of the Notes to Financial Statements). Such
rebates were contemplated as a part of the Merger and were recognized as an
expense in the period.

Federal Income Tax

Nine Months Ended December 31, 1998 and 1997

LIPA was not subject to Federal income tax for seven of the nine months in this
reporting period (May 29 to December 31, 1998), which contributed significantly
to the $241 million decrease in operating Federal income tax expense when
compared to the similar period in 1997. In addition, adjustments related to the
Merger, recorded during the two month period April 1 to May 28, 1998, also
contributed to this decrease.

The increase in non-operating Federal income tax expense of approximately $85
million for the nine months ended December 31, 1998, when compared to the
similar period in 1997, was principally the result of events which took place
during the period April 1, 1998 to May 28, 1998, including, an increase in
non-operating pretax income and various adjustments related to the Merger. These
increases were partially offset by the impact of LIPA's exemption from Federal
income taxes.

Years Ended March 31, 1998 and 1997

Federal income tax was $210 million and $179 million for the years ended March
31, 1998 and 1997, respectively. The increase in federal income tax was
primarily attributable to higher pre-tax earnings partially offset by the
utilization of investment tax credits.

Other Income and Deductions, Net

Years Ended March 31, 1998 and 1997

Other income and deductions was a $7 million charge to income for the year ended
March 31, 1998, compared to a $10 million credit to income for the same period
in 1997. The difference of approximately $17 million, relates primarily to a
charge of approximately $31 million for certain benefits earned by LILCO
officers recorded in 1998. For a further discussion of this matter, see Note 10
of Notes to Financial Statements.


                                       36
<PAGE>

Years Ended December 31, 1996 and 1995

Other income and deductions totaled a credit to income of $14 million for the
year ended December 31, 1996, compared to $31 million for the same period in
1995. The decrease in 1996, when compared to 1995, is primarily attributable to
the recognition of non-recurring expenditures associated with one of LILCO's
wholly-owned subsidiaries, a decrease in non-cash carrying charge income
associated with regulatory assets not currently in rate base and the recognition
in 1995 of certain litigation proceeds related to the construction of the
Shoreham Nuclear Power Station.

Interest Expense

Nine Months Ended December 31, 1998 and 1997

Interest expense for the nine month period ended December 31, 1998 is
approximately $11 million less than that of the similar 1997 period. This
decrease is principally attributable to the lower borrowing rates of LIPA
relative to the borrowing rates of LILCO. This decrease in interest expense was
partially offset by the higher levels of debt that LIPA has outstanding during
this period, when compared to LILCO during the similar 1997 period. This
increase in the level of debt is due to the refinancing by LIPA of LILCO's
equity.

Years Ended March 31, 1998 and 1997

Interest expense for the year ended March 31, 1998 totaled $404 million compared
to $435 million for the year ended March 31, 1997. This decrease is primarily
attributable to lower outstanding debt levels, as LILCO retired $250 million of
the General and Refunding Bonds in February 1997.

Years Ended December 31, 1996 and 1995

Interest expense for the year ended December 31, 1996 totaled $448 million,
compared to $472 million for the year ended December 31, 1995. This decrease is
primarily attributable to lower outstanding debt levels, partially offset by
higher letter of credit and commitment fees associated with the change in
LILCO's credit rating in 1996.

Liquidity and Capital Resources

Liquidity

During the period May 29, 1998 to December 31, 1998, LIPA received approximately
$6.7 billion from the Authority to finance the Merger, as more fully discussed
in Note 7 of Notes to the Financial Statements, in exchange for a Promissory
Note. All cash from customers payments and other sources is collected by the
Authority. The Authority makes all disbursements on LIPA's behalf. Accordingly,
all operating cash amounts are held at the Authority. Cash collections and
disbursements by the Authority on LIPA's behalf increase or decrease amounts due
the Authority by LIPA. LIPA has repaid approximately $448 million of its debt to
the Authority because cash collected by the Authority from customers and other
sources during this period exceeded cash paid on LIPA's behalf by the Authority.

Pursuant to the Authority's Electric System General Revenue Bond Resolution
dated May 13, 1998, all amounts to be paid by the Authority to LIPA in respect
of the debt obligations of LIPA are subordinated in right of payment to the
payment of amounts due on the debt obligations of the Authority. As a result,
all debt assumed from LILCO is structurally subordinated in right of payment to
the Authority's debt obligations. 


                                       37
<PAGE>

At December 31, 1998, the Authority's and LIPA's cash and cash equivalents
amounted to approximately $517 million. In addition, LIPA has designated funds
aggregating $195 million on hand, $62 million of which are available to fund
capital expenditures.

During 1998, pursuant to a tender offer and a notice of redemption for certain
debentures, LIPA refinanced approximately $1.5 billion of the debentures assumed
from LILCO. In addition, during 1998, LIPA defeased $323 million of the New York
State Energy Research and Development Authority ("NYSERDA") Notes assumed from
LILCO. For further discussion of the Bond refundings and defeasance see Note 7
of the Notes to the Financial Statements. Subsequent to December 31, 1998, LIPA
retired approximately $133 million of debt. In March 1999, LIPA converted
certain of its variable rate NYSERDA Bonds to a fixed rate, as more fully
described in Note 15 of Notes to the Financial Statements. LIPA believes that
cash from operations for 1999 will be sufficient to meet its operating, capital
and debt service requirements. However, LIPA will access the capital markets in
1999 in order to finance capital expenditures and to refinance higher cost debt,
if conditions prove favorable.

LIPA estimates that for 1999,  capital  spending will total  approximately  $124
million.  With respect to debt maturities subsequent to 1998, the Authority will
use cash generated from operations to satisfy such maturities.

The Authority also expects to use cash from operations to make optional
redemptions of debt in 1999. Such actions are consistent with the Authority's
plan to retire in 16 years, the approximately $4 billion it borrowed to purchase
the Shoreham regulatory assets from LILCO.

During 1998, the Authority issued rebate checks to all of its customers in the
amount of $232 for each Nassau County and Rockaway customer and $101 for each
Suffolk County customer. The total amount of the rebate program was
approximately $169 million. In addition, on May 29, 1998, LIPA began issuing
credits to the bills of customers arising from the proposed settlement of the
Shoreham Property Tax Litigation. Credits will be issued over the five years
after May 29, 1998, in the total amount of $106.3 million for Suffolk County
customers and $208 million for Nassau County and Rockaway customers. The
Authority has issued $145.7 million of bonds and has proposed to issue
additional bonds over the next four years to finance the cost of the proposed
settlement. Beginning in May 2004, a surcharge will be levied upon the Suffolk
County customers in order to repay the bonds. See Note 13 of Notes to Financial
Statements--Shoreham Tax Matters.

Capital Requirements

Capital expenditures are expected to be made by LIPA in the ordinary course of
business for purposes of the normal upgrading and expansion of the T&D System.
LIPA considers the T&D System to be adequate and in good condition. The actual
amount and timing of future financing will depend upon actual capital
expenditures, the timeliness and adequacy of rate increases, the availability
and cost of capital and the ability to meet interest and fixed charge coverage
requirements. The Authority has been advised by KeySpan that the amount of
capital expenditures budgeted to be made in 1999 is adequate to maintain system
reliability and insures customer and employee safety.

Investment Rating

Securities of the Authority and LIPA, which are not supported by letters of
credit, are rated by Fitch IBCA, Inc. ("Fitch"), Moody's Investors Services,
Inc. ("Moody's") and Standard & Poor's Rating Services, a division of the
McGraw-Hill Companies, Inc. ("S&P").

The Board of Trustees of the Authority has adopted a resolution directing
management of the Authority and LIPA to implement procedures to improve the
ratings on the debt of the Authority and LIPA. To date, no such procedures have
been implemented and there can be no assurance that such procedures, if and when
implemented will improve the ratings.

Impact of Year 2000

General.

A portion of the computer hardware and software and embedded technology (such as
microcontrollers and microprocessors contained in equipment and machinery) used
by the Authority and LIPA, as well as KeySpan and the subsidiaries of KeySpan
that are parties to the MSA, EMA and PSA and others with whom the foregoing have
business arrangements, was not designed to recognize calendar years after 1999
(the "Year 2000 Issue").

The Authority recently purchased new computer software to support certain
activities of LIPA and believes that these systems are Year 2000 ready.
Management also believes that, based on available information, it will be able
to manage its Year 2000 transition for systems and infrastructure, without any
material adverse effect on its business operations or financial prospects.
However, there can be no assurance that failure to resolve any issue relating to
such transition would not have a material adverse effect on LIPA. LIPA has had
continuing discussions with KeySpan, their largest vendor, who is responsible
for the management and operation of LIPA's transmission and distribution system,
and KeySpan indicates that they have evaluated the extent to which modifications
to computer software, hardware and databases will be necessary to accommodate
the year 2000.

KeySpan's computer applications are generally based on two digits and do require
additional programming to recognize the new millennium. A corporate-wide program
has been established by KeySpan and its subsidiaries. The program includes both
information technology ("IT") and non-IT systems. The critical non-IT systems
are generally in the areas of electric production, distribution, transmission,
gas distribution and communications. The readiness of suppliers and vendor
systems is also under review. The project is under the direction of KeySpan's
Year 2000 Program Office, chaired by the Vice President, Technology Operations
and Corporate Y2K Officer. Each of KeySpan's critical business processes is
being reviewed to: identify and inventory sub-components; assess for Year 2000
compliance; 


                                       39
<PAGE>

establish repair plans as necessary; and test in a Year 2000 environment. The
inventory phase for the IT systems and non-IT systems is 100% complete. The
assessment phase is 100% complete for the IT systems, and over 90% complete for
non-IT systems. The assessment phase is expected to be complete by July 1, 1999.

KeySpan's hardware, software and embedded systems are being tested and certified
to be Year 2000 compliant. Repair and testing to sustain operability is now 73%
complete for the IT systems and approximately 75% for the non-IT systems.
Components needed to support the critical business process and associated
business contingency plans are expected to be ready for the year 2000 by July 1,
1999.

KeySpan's vendors and business partners needed to support the critical business
processes of KeySpan are also being reviewed for their year 2000 compliance. At
this time, none of these vendors have indicated to Key Span that they will be
materially affected by the year 2000 problem.

Key-Span has analyzed each of the critical business processes to identify
possible Year 2000 risks. Each of KeySpan's critical businesses will be
certified by the responsible KeySpan officer as being Year 2000 ready. However,
the most reasonable likely worst case scenarios are also being identified.
Business operating procedures at KeySpan will be reviewed to ensure that risks
are minimized when entering the Year 2000 and other high risk dates. KeySpan is
developing contingency plans to address possible failure points in each critical
business process.

While KeySpan must plan for the following worst case scenarios, management
believes that these events are improbable.

Loss of generating flexibility:

KeySpan's generation subsidiary receives gas delivery from multiple national and
international pipelines and, therefore the effects of a loss in any one pipeline
can be mitigated through the use of other pipelines. Complete loss of all the
supply lines is not considered a reasonable scenario. Nevertheless, the impact
of the loss of any one pipeline is dependent on temperature and vaporization
rate. The partial loss of gas supply will not affect KeySpan's ability to supply
electricity since many of the plants have the ability to operate on oil.

Loss of electric grid inter-connections/KeySpan operated electric distribution
facilities: Electric utilities are physically connected on a regional basis to
manage electric load. This is often referred to as the regional grid. Presently,
KeySpan is working with other regional utilities to develop a coordinated
operating plan. Should there be an instability in the grid, KeySpan has the
ability to remove LIPA's operations from the grid, and operate independently.

Certain electric system components such as individual generating units,
transmission and distribution system facilities, and the electric energy
management system have the potential to malfunction due to Year 2000 problems.
KeySpan has inventoried electric system components and developed a plan to
certify mission critical processes as Year 2000 compliant. Contingency plans are
being developed, where appropriate, for loss of critical system elements.
KeySpan presently estimates that contingency plans regarding its electric
facilities should be completed by July 1999.

Loss of telecommunications:

KeySpan has a substantial dependency on many telecommunication systems and
services for both internal and external communications. External communications
with the public and the ability of customers to contact KeySpan in cases of
emergency response is essential. KeySpan intends to coordinate its emergency
response efforts with the offices of emergency management of the various local
governments within its service territory. Internally, there are a number of
critical processes in both the gas and electric 


                                       40
<PAGE>

operating areas that rely on external communication providers. Contingency plans
will address methods for manually monitoring these functions. These contingency
plans, KeySpan presently estimates, should be finalized by July 1999.

In addition to the above, KeySpan is also planning for the following scenarios:
short-term reduction in system power generating capability; limitation of fuel
oil operation; reduction in quality of power output; loss of automated meter
reading; loss of ability to read, bill and collect; and loss of the purchasing/
materials management system.

KeySpan believes that, with modifications to existing software and conversions
to new hardware and software, the Year 2000 issue will not pose significant
operational problems for its computer systems. However, if such modifications
and conversions are not made, or are not completed on time, and contingency
plans fail the Year 2000 issue could have a material adverse impact on the
operations of LIPA.

LIPA's Contingency Plans

In order to insure that the Year 2000 will have a minimal impact on the
operations of LIPA, LIPA is closely monitoring the initiatives and progress of
KeySpan's Year 2000 Program Office. In addition, LIPA is working with various
other governmental agencies to insure communication between LIPA and such other
governmental entities is uninterrupted.

Rate Matters

For a discussion of Rate Matters, see Note 4 of Notes to Financial Statements.

Competitive Environment

Fostering competition in wholesale and retail electric power has become a
significant policy goal in many states, including New York, as well as at the
federal level. The fostering of competition has been accompanied by and requires
separating power supply services and costs from electric transmission and
distribution services and costs. In New York and many other states, there have
been regulatory actions to promote competition in the supply of power by
requiring, among other things, that utilities sell all or part of their
non-nuclear generating plants. Federal regulation of transmission has been the
focus of increasing action and attention as transmission is viewed as the
vehicle for delivery of competitively priced generation to wholesale and retail
customers. In general, transmission and distribution is viewed as an inherently
monopoly function that must remain regulated.

The Merger accomplished the disaggregation of ownership of power supply (with
the exception of the 18% interest in NMP2) from the provision of transmission
and distribution services in the Service Area. Through the Merger, the ownership
and operation of the transmission and distribution system on Long Island became
LIPA's business and responsibility, and the on-island generating resources
became owned by, and the responsibility of, KeySpan. The PSA provides for
KeySpan to supply LIPA with all of the capacity and to the extent LIPA requests,
energy from the electric generation facilities on Long Island previously owned
by LILCO. LIPA continues to own an 18% interest in NMP2, which is not on Long
Island and which is operated by Niagara Mohawk Power Corporation.

The Authority's effort at creating competition in power supply resources is to
gradually create a competitive retail market for power supply. The Authority has
adopted a customer retail choice plan intended to lead to full choice among
power suppliers by all retail customers by 2003. Under the retail choice plan,
the Authority will initially provide customers representing an aggregate load of
400 MW the option of selecting competitive suppliers of electric capacity and
energy. During this initial phase of the 


                                       41
<PAGE>

retail choice plan, anticipated to begin by August 1, 1999, available program
load will be apportioned among residential and other classes of customers.
Approximately 90,000 residential customers will be eligible to participate.

Regardless of a customer's choice of electricity supplier, LIPA will remain the
sole provider of transmission and distribution services to customers in the
Service Area. LIPA plans to set rates for delivery service to include all costs
that are not avoidable once customers choose alternative suppliers, with the
intent that the Authority be kept revenue neutral. Costs that the Authority will
not be able to avoid, and therefore will be included in the rates for delivery
service, include its debt service obligations and any long-term power purchase
contracts, among other items. The Authority's retail choice plan has been
designed to assume that LIPA will continue to recover all costs needed for safe
and reliable T&D System operation and to meet its financial obligations,
regardless of customer participation in the Authority's retail choice program.

Customers could reduce LIPA's role of supplying and delivering electric capacity
and energy through the installation of their own generating facilities.
Self-generation is most attractive to customers who are high energy load factor
users, such as hospitals, or manufacturers with multiple shift operations. There
are few such customers of significant size on Long Island.

Recent Accounting Pronouncements

Derivative Instruments

In June 1998, FASB issued SFAS No. 133, "Accounting for Derivative Instruments
and Hedging Activities." This Statement establishes accounting and reporting
standards for derivative instruments and for hedging activities. It requires
that an entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value.
LIPA will adopt SFAS No. 133 in the first quarter of fiscal year 2000. LIPA does
not expect any material earnings effect from adoption of this statement.

Plant Decommissioning

In February 1996, the FASB issued an exposure draft entitled "Accounting for
Certain Liabilities Related to Closure and Removal of Long-Lived Assets," which
includes nuclear plant decommissioning. Over the past two years, this exposure
draft has been the source of continual debate. The FASB has committed to
completing the project and is proceeding toward issuance of another exposure
draft (expected in the second quarter of 1999). If the accounting standard
proposed in such exposure draft were adopted, it could result in higher annual
provisions for removal or decommissioning to be recognized earlier in the
operating life of nuclear and other generating units and an accelerated
recognition of the decommissioning obligation. The FASB is continuing to explore
various issues associated with this project including liability measurement and
recognition issues. In addition, an effective date for the new exposure draft
has not yet been determined. The FASB is deliberating this issue and the
resulting final pronouncement could be different from that proposed in the
exposure draft. LIPA can make no prediction at this time as to the ultimate form
of such proposed accounting standard, assuming it is adopted, nor can it make
any prediction as to its ultimate effect(s) on the financial condition of LIPA.

Investments

GASB Statement No. 31, "Accounting and Financial Reporting for Certain
Investments and for External Investment Pools," was implemented during the
period ending December 31, 1998. The statement generally requires that
investments should be reported in the balance sheet at fair value and that
realized and unrealized gains and losses on investments flow through the
statement of operations. The impact of this statement did not have a material
impact on LIPA.

Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

                   Report of Independent Accountants

To the Board of Directors
Long Island Lighting Company d/b/a LIPA

In our opinion, the accompanying balance sheet and statement of capitalization
and the related statements of operations, (accumulated deficit) retained
earnings and of cash flows present fairly, in all material respects, the
financial position of Long Island Lighting Company d/b/a LIPA ("LIPA") at
December 31, 1998, and the results of its operations and its cash flows for the
period May 29, 1998 to December 31, 1998 in conformity with generally accepted
accounting principles. These financial statements are the responsibility of
LIPA's management; our responsibility is to express an opinion on these
financial statements based on our audit. The accompanying financial statements
of the Long Island Lighting Company as of March 31, 1998 and December 31, 1996
and for the years ended March 31, 1998 and December 31, 1996 and for the three
months ended March 31, 1997 were audited by other auditors whose report thereon
dated May 22, 1998, expressed an unqualified opinion on those statements, before
the restatement described in Note 2 to the financial statements. We conducted
our audit of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audit provides a reasonable basis for the opinion expressed above.

We also audited the adjustments described in Note 2 that were applied to restate
the statement of operations for the years ended March 31, 1998 and December 31,
1996 and the three months ended March 31, 1997, for discontinued operations
treatment. In our opinion, such adjustments are appropriate and have been
properly applied.

The year 2000 supplementary information on page 94 is not a required part of the
basic financial statements but is supplementary information required by the
Governmental Accounting Standards Board, and we did not audit and do not express
an opinion on such information. Further, we were unable to apply to the
information certain procedures required by professional standards because the
disclosure criteria specified by TB 98-1, as amended, are not sufficiently
specific and, therefore, preclude the prescribed procedures from providing
meaningful results. In addition, we do not provide assurance that LIPA is or
will become year 2000 compliant, that LIPA's year 2000 remediation efforts will
be successful in whole or in part, or that parties with which LIPA does business
are or will become year 2000 compliant.

Report of Ernst & Young LLP, Independent Auditors

To the Shareowners and Board of Directors of Long Island Lighting Company:

We have audited the accompanying balance sheet of Long Island Lighting Company
and the related statement of capitalization as of March 31, 1998 and December
31, 1996 and the related statements of income (prior to restatement to present
the gas business as a discontinued operations), retained earnings and cash flows
for the year ended March 31, 1998, the three months ended March 31, 1997 and the
year ended December 31, 1996. Our audits also included the financial statement
schedule listed in the index at Item 14(a). These financial statements and
schedule are the responsibility of the Company's management. Our responsibility
is to express an opinion on these financial statements and schedule based on our
audits. We did not audit the restatements described in Note 2 to present the
operations of the gas business as a discontinued operation for the years ended
March 31, 1998 and December 31, 1996 and the three months ended March 31, 1997.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Long Island Lighting Company at
March 31, 1998 and December 31, 1996 and the results of its operations (prior to
restatement) and its cash flows for the year ended March 31, 1998, the three
months ended March 31, 1997 and the year ended December 31, 1996, in conformity
with generally accepted accounting principles. Also, in our opinion the related
financial statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly in all material respects the
information set forth therein.

During the year ended March 31, 1998 the Company changed its method of
accounting for revenues provided for under the Rate Moderation Component.

Long Island Lighting Company d/b/a LIPA
(a wholly-owned subsidiary of the Long Island Power Authority)

Notes to Financial Statements
--------------------------------------------------------------------------------
Note 1. Basis of Presentation

As used herein, the term "LILCO" refers to the Long Island Lighting Company, the
publicly owned gas and electric utility company as it existed prior to the
LIPA/LILCO Merger, as described in Note 2, and the term "LIPA" refers to that
company as it exists after the LIPA/LILCO Merger as a wholly-owned electric
utility subsidiary company of the Long Island Power Authority (the "Authority"),
doing business as LIPA.

The Authority was established as a corporate municipal instrumentality of the
State of New York, constituting a political subdivision of the State, created by
Chapter 517 of the Laws of 1986 (the "LIPA Act"). As such, it is a component
unit of the State and is included in the State's annual financial statements.

On April 11, 1997, LILCO changed its year-end from December 31 to March 31.
Subsequent to the LIPA/LILCO Merger, LIPA adopted a calendar year-end.
Accordingly, unless otherwise indicated, references to December 1998 and
December 1997 represent the nine month periods ended December 31, 1998 and
December 31, 1997, respectively . References to March 31, 1998 represent the
twelve month period then ended. References to March 31, 1997 represent the three
month period then ended, while references to all other periods refer to the
calendar years ended December 31.

Note 2. Merger/Change in Control

On May 28, 1998, LIPA Acquisition Corp., a wholly-owned subsidiary of the
Authority, was merged with and into LILCO (the "Merger") pursuant to an
Agreement and Plan of Merger dated as of June 26, 1997, by and among LILCO,
MarketSpan Corporation (formerly known as BL Holding Corp., and currently known
as KeySpan Energy, "KeySpan"), the Authority and LIPA Acquisition Corp., (the
"Merger Agreement").

Pursuant to the Merger Agreement, immediately prior to the Merger, all of the
assets and liabilities of LILCO related to the conduct of its gas distribution
business and its non-nuclear electric generation business, and all common assets
used by LILCO in the operation and management of its electric transmission and
distribution business and its gas distribution business and/or its non-nuclear
electric generation business (the "Transferred Assets") were sold to KeySpan.
The consideration received by LILCO for the Transferred Assets consisted of: (i)
3,440,625 shares of the common stock of KeySpan; (ii) 553,000 shares of the
Series B Preferred Stock of KeySpan; and (iii) 197,000 shares of the Series C
Preferred Stock of KeySpan.

The value of the consideration was determined by KeySpan and LILCO to be equal
to the net fair market value of the Transferred Assets. The transfer of assets
and liabilities was effected by a Bill of Sale, dated as of May 28, 1998, made
and executed by LILCO and acknowledged by KeySpan.

As a result of the Merger, the Authority became the holder of 1 share of LILCO's
common stock, representing 100% of the outstanding voting securities of LILCO.
In addition, KeySpan issued promissory notes to LIPA of approximately $1.048
billion. The interest rate and timing of principal and interest payments on the
promissory notes from KeySpan are identical to the terms of certain LILCO


                                       54

--------------------------------------------------------------------------------

indebtedness assumed by the LIPA in the Merger. KeySpan is required to make
principal and interest payments to LIPA thirty days prior to the corresponding
payment due dates, and LIPA then transfers those amounts to debtholders in
accordance with the original debt repayment schedule.

The former holders of LILCO's common stock, primarily individual public
shareowners, became entitled to receive a pro-rata share of: (i) cash
consideration of $2.497 billion; and (ii) 3,440,625 shares of the common stock
of KeySpan, which were received by LILCO in exchange for the Transferred Assets.
Pursuant to the Merger Agreement, the former holders of LILCO's common stock
(other than holders of dissenting shares) were deemed to have subscribed for
additional shares of the common stock of KeySpan, with an aggregate purchase
price equal to the cash consideration. In order to effect the Merger, it was
necessary to: (i) retire all shares of LILCO's preferred stock, whether by
conversion, redemption or cancellation; and (ii) redeem certain of LILCO's
bonds, at a cost to LIPA of approximately $1.557 billion. The cash consideration
required for the Merger was obtained by the Authority from the proceeds of the
issuance and sale of its Electric System General Revenue Bonds, Series 1998A and
Electric System Subordinated Revenue Bonds, Series 1 through Series 6. The
proceeds from the sale of the bonds were then transferred by the Authority to
LIPA in exchange for a promissory note of approximately $4.949 billion. As a
result of the Merger, there was a change in control of LILCO which effectively
resulted in the creation of a new reporting entity, LIPA. Accordingly, the
accompanying financial statements for the periods prior to and including May 28,
1998 are not comparable to the financial statements presented subsequent to May
28, 1998. Therefore, a black line has been drawn on the accompanying financial
statements to distinguish between LIPA and LILCO balances and activity.

The remaining assets and liabilities of LILCO acquired by LIPA consist of: (i)
LILCO's electric transmission and distribution system; (ii) its net investment
in Nine Mile Point Nuclear Power Station, Unit 2 ("NMP2"); (iii) certain
regulatory assets and liabilities associated with its electric business, (iv)
allocated accounts receivable and other assets and liabilities; and (v)
substantially all of its long-term debt.

The financial statements of LIPA include the push down of the Authority's basis,
including costs related to the acquisition, in the assets acquired and
liabilities assumed. Because of the manner in which LIPA's rates and charges
will be established by the Authority's Board of Trustees, the original net book
value of the transmission and distribution and nuclear generation assets
acquired in the Merger is considered to be their fair value. The excess of the
acquisition costs over the fair value of the net assets acquired has been
recorded as an intangible asset titled "acquisition adjustment" and is being
amortized over a 35 year period, the weighted average useful life of the net
plant assets acquired. The acquisition adjustment principally arose through the
elimination of LILCO's regulatory assets and liabilities, totaling $6.3 billion,
and net deferred federal income tax liability of approximately $2.4 billion.
Therefore, the amortization of the regulatory assets and liabilities has
effectively been replaced by the amortization of the acquisition adjustment. In
addition, as a wholly-owned subsidiary of the Authority, LIPA is exempt from
Federal, state and local income taxes. Accordingly, adjustments were made by
LIPA on May 28, 1998 to eliminate deferred tax assets and liabilities.
Therefore, the results of operations for the period May 29, 1998 to December 31,
1998 do not include a provision for income taxes.

Effective May 29, 1998, LIPA contracted with KeySpan to provide operations and
management services for LIPA's transmission and distribution system through a
management services agreement. Therefore, 


                                       55

Notes to Financial Statements
--------------------------------------------------------------------------------

LIPA pays KeySpan directly for their services and KeySpan, in turn, pays the
salaries of their employees. LIPA has no employees, however LIPA is charged a
management fee by the Authority to oversee LIPA's operations of which the
salaries of the Authority's employees is a significant component. LIPA contracts
for capacity from the fossil fired generating plants of KeySpan through a power
supply agreement. Energy and fuel are purchased by KeySpan on LIPA's behalf
through an energy management agreement (collectively; the "Operating
Agreements").

The electric transmission and distribution system is located in the New York
Counties of Nassau and Suffolk (with certain limited exceptions) and a small
portion of Queens County known as the Rockaways. The service area covers an area
of approximately 1,230 square miles and the population of the service area is
approximately 2.75 million persons, including approximately 98,500 persons who
reside in Queens County within the City of New York. LIPA receives approximately
49% of its revenues from residential sales, 48% from sales to commercial and
industrial customers, and the balance from sales to other utilities and public
authorities. 

2. Discontinued Operations

The statement of operations of LILCO for the period April 1, 1998 to May 28,
1998 has been prepared to present the gas business (as transferred to KeySpan
subsidiaries pursuant to the Merger Agreement) as a discontinued operation, in
accordance with the provisions of Accounting Principles Board Opinion No. 30.
The statements of operations for the years ended March 31, 1998 and December 31,
1996 and the three months ended March 31, 1997, have also been restated to
present the gas business in a similar manner.

The income from discontinued operations includes revenue from the gas business
of approximately $79.9 million, $645.6 million, $684.2 million and $293.4
million for the period April 1, 1998 to May 28, 1998, the years ended March 31,
1998 and December 31, 1996 and the three months ended March 31, 1997,
respectively.

Note 3. Summary of Significant Accounting Policies

General

LIPA complies with all applicable pronouncements of the Governmental Accounting
Standards Board ("GASB"). In accordance with GASB Statement No. 20, "Accounting
and Financial Reporting for Proprietary Funds and Other Governmental Entities
That Use Proprietary Fund Accounting," LIPA also complies with all authoritative
pronouncements applicable to non-governmental entities (i.e., Financial
Accounting Standards Board ("FASB") statements) that do not conflict with GASB
pronouncements.

LILCO maintained its accounting records in accordance with the Uniform Systems
of Accounts prescribed by the Public Service Commission of the State of New York
("PSC") and the Federal Energy Regulatory Commission ("FERC"). Its financial
statements reflected the ratemaking policies and actions of these Commissions in
conformity with generally accepted accounting principles for rate-regulated
enterprises.

Notes to Financial Statements
--------------------------------------------------------------------------------

Accounting for the Effects of Rate Regulation

Under current New York law, the Authority is empowered to set rates for electric
service in LIPA's service area without being required by law to obtain the
approval of the New York State Public Service Commission (the "PSC") or any
other State regulatory body. 

Both LILCO and LIPA are subject to the provisions of Statement of Financial
Accounting Standards ("SFAS") No. 71, "Accounting for the Effects of Certain
Types of Regulation." This statement recognizes the economic ability of
regulators, through the ratemaking process, to create future economic benefits
and obligations affecting rate-regulated companies. Accordingly, LIPA records
these future economic benefits and obligations as regulatory assets and
regulatory liabilities, respectively.

Regulatory assets represent probable future revenues associated with previously
incurred costs that are expected to be recovered from customers. Regulatory
liabilities represent probable future reductions in revenues associated with
amounts that are expected to be refunded to customers through the ratemaking
process.

Utility Plant

Utility plant is stated at cost for LILCO, and fair values, at the date of the
Merger, for LIPA. Additions to and replacements of utility plant are capitalized
at original cost, which includes material, labor, indirect costs associated with
an addition or replacement, plus an allowance for funds used during
construction. The cost of renewals and betterments relating to units of property
is added to utility plant. The cost of property replaced, retired or otherwise
disposed of is deducted from utility plant and, generally, together with
dismantling costs less any salvage, is charged to accumulated depreciation. The
cost of repairs and minor renewals is charged to maintenance expense. Mass
properties (such as poles, wire and meters) are accounted for on an average unit
cost basis by year of installation.

Depreciation

The provisions for depreciation result from the application of straight-line
rates to the original cost for LILCO, fair values at the date of the Merger for
LIPA, by groups, of depreciable properties in service. The rates are determined
by age-life studies performed on depreciable properties. The average
depreciation rate as a percentage of respective average depreciable plant costs
was as follows:

Allowance for Funds Used During Construction

The Allowance For Funds Used During Construction ("AFC") is the net cost of
borrowed funds used for construction purposes and a reasonable rate of return
upon a utility's equity when so used. AFC is not an item of current cash income.
AFC is computed monthly on a portion of construction work in progress.

(a) Cost of borrowed funds only.

Designated Funds

Designated funds are certificates of deposit and highly liquid investments with
maturities of three months or less when purchased and are valued at amortized
cost, which approximates market value at December 31, 1998. These funds have
been designated by the Authority's Board of Trustees to be used for specific
purposes, including debt service and capital expenditures. LIPA's designated
funds are held by the Authority in an investment pool that is administered in
accordance with the Authority's investment guidelines pursuant to Section 2925
of the New York State Public Authorities Law. These guidelines comply with the
New York State Comptroller's investment guidelines for public authorities. The
certificates of deposit are either insured by the FDIC or collateralized by
securities held by the Authority's custodian bank in the Authority's name.
Investments are comprised of commercial paper rated A-1 by Standard & Poor's
Corporation or P-1 by Moody's Commercial Paper Record.

Statement No. 3 of the Governmental Accounting Standards Board, "Investments,
including Repurchase Agreements" ("GASB 3"), requires state and local
governments to classify their investments in three defined categories of credit
risk. Category one includes investments that are insured or registered, or
securities that are held by the Authority or its agent in the Authority's name.
The investments held by the Authority are classified as Category one at December
31, 1998.

Fair Values of Financial Instruments

The fair values for LILCO's and LIPA's long-term debt and redeemable preferred
stock are based on quoted market prices, where available. The fair values for
all other long-term debt and redeemable preferred stock were estimated using
discounted cash flow analyses based upon LILCO or LIPA's current incremental
borrowing rate for similar types of securities.

Revenues

Revenues are comprised of cycle billings rendered to customers and the accrual
of electric and/or gas revenues for services rendered to customers not billed at
month-end.

LILCO's electric rate structure provided for a revenue reconciliation mechanism
which eliminated the impact on earnings of electric sales that were above or
below the levels reflected in rates. LIPA's rate structure does not include a
similar mechanism.

<PAGE>

Long Island Lighting Company d/b/a LIPA

Notes to Financial Statements
--------------------------------------------------------------------------------

LILCO's gas rate structure provided for a weather normalization clause which
reduced the impact on revenues of experiencing weather which was warmer or
colder than normal.

Fuel and Purchased Power Cost Adjustment ("FPPCA")

LIPA's rates include the FPPCA mechanism whereby rates may be adjusted to
reflect significant changes in the cost of fuel, purchased power and related
costs. The FPPCA is designed to ensure that LIPA will recover from or return to
customers any fuel costs that fall outside an established base fuel and
purchased power tolerance band. The tolerance band is equal to 1% above and 1%
below LIPA's base cost of fuel and purchased power costs for 1999. The tolerance
band increases to two percent in 2000 and continue to increase in one percent
increments annually thereafter. Expenses for fuel and purchased power costs in
excess of or below this level will be recovered from or returned to customers
beginning the following year. Should fuel and purchased power costs increase in
excess of five percent cumulatively over the original base cost, the FPPCA will
recover, from that year forward, all costs in excess of the original base.

Under LIPA's current tariffs, the measurement of the under or over recovery of
fuel costs was scheduled to begin January 1, 1999. However, as a result of
decreasing fuel costs, LIPA recovered from customers approximately $22 million
more for fuel than was incurred for the period May 29, 1998, through December
31, 1998. In order to preserve this benefit for customers, LIPA recorded a
liability for the full amount of the over recovery. This amount is included in
deferred credits.

Fuel Cost Adjustments

LILCO's electric and gas tariffs included fuel cost adjustment ("FCA") clauses
which provided for disposition of the difference between actual fuel costs and
the fuel costs allowed in LILCO's base tariff rates (base fuel costs). LILCO
deferred the differences to future periods in which they would be billed or
credited to customers, except for base electric fuel costs in excess of actual
electric fuel costs, which were credited to the Rate Moderation Component
("RMC") as incurred. Gas fuel costs were excluded from base fuel costs and
recovered through Gas fuel adjustment clause under LILCO's tariff.

Federal Income Tax

LIPA is exempt from Federal, state and local income taxes.

LILCO provided deferred federal income tax with respect to items with different
bases for financial and tax reporting purposes.

LILCO deferred the benefit of 60% of pre-1982 gas and pre-1983 electric and 100%
of all other investment tax credits, with respect to regulated properties, when
realized on its tax returns. Accumulated deferred investment tax credits were
amortized ratably over the lives of the related properties.

For ratemaking purposes, LILCO provided deferred federal income tax with respect
to certain differences between income before income tax for financial reporting
purposes and taxable income for federal income tax purposes. Also, certain
accumulated deferred federal income taxes were deducted from rate base and
amortized or otherwise applied as a reduction in federal income tax expense in
future years.

Reserves for Claims and Damages

Losses arising from claims against LIPA, including workers' compensation claims,
property damage,

extraordinary storm costs and general liability claims, are partially
self-insured. Reserves for these claims and damages are based on, among other
things, experience and risk of loss. Extraordinary storm losses incurred by LIPA
are partially insured by various commercial insurance carries. These insurance
carriers provide partial insurance coverage for individual storm losses to the
transmission and distribution system between $15 million and $35 million. Storm
losses which are outside of this range are self-insured by LIPA.

Use of Estimates

The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

Reclassifications

Certain prior period amounts have been reclassified in the financial statements
to conform with the current period presentation.

Recent Accounting Pronouncements

Derivative Instruments

In June 1998, FASB issued SFAS No. 133, "Accounting for Derivative Instruments
and Hedging Activities." This Statement established accounting and reporting
standards for derivative instruments and for hedging activities. It requires
that an entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value.
LIPA will adopt SFAS No. 133 in the first quarter of fiscal year 2000. LIPA does
not expect any material earnings effect from adoption of this statement.

Plant Decommissioning

In February 1996, the FASB issued an exposure draft entitled "Accounting for
Certain Liabilities Related to Closure and Removal of Long-Lived Assets," which
includes nuclear plant decommissioning. Over the past two years, this exposure
draft has been the source of continual debate. The FASB has committed to
completing the project and is proceeding toward issuance of another exposure
draft (expected in the second quarter of 1999). If the accounting standard
proposed in such exposure draft were adopted, it could result in higher annual
provisions for removal or decommissioning to be recognized earlier in the
operating life of nuclear and other generating units and an accelerated
recognition of the decommissioning obligation. The FASB is continuing to explore
various issues associated with this project including liability measurement and
recognition issues. In addition, an effective date for the new exposure draft
has not yet been determined. The FASB is deliberating this issue and the
resulting final pronouncement could be different from that proposed in the
exposure draft. LIPA can make no prediction at this time as to the ultimate form
of such proposed accounting standard, assuming it is adopted, nor can it make
any prediction as to its ultimate effect(s) on the financial condition of LIPA.

Investments

GASB Statement No. 31, "Accounting and Financial Reporting for Certain
Investments and for External Investment Pools," was implemented during the
period ending December 31, 1998. The statement generally requires that
investments should be reported in the balance sheet at fair value and that

and unrealized gains and losses on investments flow through the statement of
operations. The adoption of this statement did not have a material impact on
LIPA.

Regulatory Assets and Liabilities of LILCO

Base Financial Component and Rate Moderation Component

Pursuant to the 1989 Settlement (as described in Note 11), LILCO recorded a
regulatory asset known as the Financial Resource Asset ("FRA"). The FRA was
designed to provide LILCO with sufficient cash flows to assure its financial
recovery. The FRA had two components, the Base Financial Component ("BFC") and
the RMC.

The BFC represented the present value of the future net-after-tax cash flows
which the Rate Moderation Agreement ("RMA"), one of the constituent documents of
the 1989 Settlement, provided LILCO for its financial recovery. The BFC was
granted rate base treatment under the terms of the RMA and was included in
LILCO's revenue requirements through amortization included in rates over a
forty-year period on a straight-line basis which began July 1, 1989.

The RMC reflected the difference between LILCO's revenue requirements under
conventional ratemaking and the revenues resulting from the implementation of
the rate moderation plan provided for in the RMA. The RMA was adjusted, on a
monthly basis, for LILCO's share of certain NMP2 operations and maintenance
expenses, fuel credits resulting from LILCO's electric fuel cost adjustment
clause and gross receipts tax adjustments related to the FRA.

In April 1998, the PSC authorized a revision to LILCO's method for recording its
monthly RMC amortization. Prior to this revision, the amortization of the annual
level of RMC was recorded monthly on a straight-line basis, levelized basis over
LILCO's rate year which ran from December 1 to November 30. However, revenue
requirements fluctuated from month to month based upon consumption, which was
greatly impacted by the effects of weather. Under the revised method, effective
December 1, 1997, the monthly amortization of the annual RMC level varied based
upon each month's forecasted revenue requirements, which more closely aligned
such amortization with LILCO's cost of service. As a result of this change, for
the period April 1, 1998 through May 28, 1998, and for the fiscal year ended
March 31, 1998, LILCO recorded approximately $51.5 and $65.1 million,
respectively, more of non-cash RMC credits to income (representing accretion of
the RMC balance), or $33.5 million and $42.5 million net of tax, more than it
would have under the previous method.

Shoreham Post-Settlement Costs

Shoreham post-settlement costs consisted of Shoreham decommissioning costs, fuel
disposal costs, Payments-In-Lieu-Of-Taxes ("PILOT's"), carrying charges and
other costs. These costs were being capitalized and amortized and recovered
through rates over a forty-year period on a straight-line remaining life

basis which began July 1, 1989.

Shoreham Nuclear Fuel

Shoreham nuclear fuel principally reflected the unamortized portion of Shoreham
nuclear fuel which was reclassified from Nuclear Fuel in Process and in Reactor
at the time of the 1989 Settlement. This amount was being amortized and
recovered through rates over a forty-year period on a straight-line remaining
life basis which began July 1, 1989.

Unamortized Cost of Issuing Securities

Unamortized cost of issuing securities represented the unamortized premiums or
discounts and expenses related to the issues of long-term debt that had been
retired by LILCO prior to maturity and the costs associated with the early
redemption of those issues. In addition, this balance included the unamortized
capital stock expense and redemption costs related to certain series of
preferred stock that had been refinanced by LILCO. These costs were amortized
and recovered through rates, as provided by the PSC, over the shorter of the
life of the redeemed issue or the new issue.

Postretirement Benefits Other Than Pensions

LILCO deferred as a regulatory asset the difference between postretirement
benefits expense recorded in accordance with SFAS No. 106, "Employers'
Accounting for Postretirement Benefits Other Than Pensions," and postretirement
benefits expense reflected in rates. Pursuant to a PSC order, the ongoing annual
SFAS No. 106 benefit expense was phased into and fully reflected in rates by
November 30, 1997, with the accumulated deferred asset to be recovered in rates
over the fifteen-year period which began December 1, 1997.

Regulatory Tax Asset and Regulatory Tax Liability

LILCO had recorded a regulatory tax asset for amounts that if would have
collected in future rates for the portion of its deferred tax liability that had
not been recognized for ratemaking purposes. The regulatory tax asset was
comprised principally of the tax effect of the difference in the cost basis of
the BFC for financial and tax reporting purposes, depreciation differences not
normalized and the allowance for equity funds used during construction.

The regulatory tax liability was primarily attributable to deferred taxes
previously recognized by LILCO at rates higher than the then current enacted tax
law, unamortized investment tax credits and tax credit carryforwards.

Regulatory Liability Component

Pursuant to the 1989 Settlement (as discussed in Note 12), certain tax benefits
attributable to the Shoreham abandonment were to be shared between electric
customers and shareowners. A regulatory liability of approximately $794 million
was recorded in June 1989 to preserve an amount equivalent to the customer tax
benefits attributable to the Shoreham abandonment. This amount was being
amortized over a ten-year period on a straight-line basis which began July 1,
1989.

1989 Settlement Credits

Represented the unamortized portion of an adjustment of the book write-off to
the negotiated 1989 Settlement amount. A portion of this amount was being
amortized over a ten-year period which began on July 1, 1989. The remaining
portion was not being recognized for ratemaking purposes.

LRPP Payable

Under the provisions of LILCO's rate structure, the LRPP Payable represented the
then current portion of amounts due to ratepayers that resulted from the revenue
and expense reconciliations, performance-based

incentives and associated carrying charges as established under the LILCO
Ratemaking and Performance Plan ("LRPP").

Note 4. LIPA Rate Matters

Under current New York law, the Authority is empowered to set rates for electric
service in its service area without being required by law to obtain the approval
of the PSC or any other state regulatory body. However, the Authority has
agreed, in connection with the approval of the Merger by the New York State
Public Authorities Control Board (the "PACB"), that it will not impose any
permanent increase, nor extend or reestablish any portion of a temporary rate
increase, in average customer rates over a 12 month period in excess of 2.5%
without approval of the PSC, following a full evidentiary hearing. Another of
the PACB conditions requires that the Authority reduce average rates within
LIPA's service area by no less than 14% over a ten year period commencing on the
date when LIPA began providing electric service, when measured against LILCO's
base rates in effect on July 16, 1997 (excluding the impact of the proposed
Shoreham tax settlement, but adjusted to reflect emergency conditions and
extraordinary unforeseeable events.)

The LIPA Act requires that any bond resolution of the Authority contain a
covenant that it will at all times maintain rates, fees or charges sufficient to
pay the costs of operation and maintenance of facilities owned or operated by
the Authority; PILOT's; renewals, replacements and capital additions; the
principal of and interest on any obligations issued pursuant to such resolution
as the same become due and payable, and to establish or maintain any reserves or
other funds or accounts required or established by or pursuant to the terms of
such resolution.

LIPA's rates include the FPPCA to adjust rates to reflect significant changes in
the cost of fuel, purchased power and related costs. The FPPCA is designed to
ensure that LIPA will recover from or return to customers any fuel costs that
fall outside an established base fuel and purchased power tolerance band. The
tolerance band is equal to 1% above and 1% below LIPA's base cost of fuel and
purchased power costs for 1999. The tolerance band increases to two percent in
2000 and continues to increase in one percent increments annually thereafter.
Expenses for fuel and purchased power costs in excess of or below this level
will be recovered from or returned to customers beginning the following year.
Should fuel and purchased power costs increase in excess of five percent
cumulatively over the original base cost, the FPPCA will recover, from that year
forward, all costs in excess of the original base.

LIPA's rates are largely based on LILCO's pre-Merger rate design to avoid
customer confusion and facilitate an efficient transition from LILCO billing to
LIPA billing. In addition, LIPA's rates include the FPPCA, a PILOT payments
recovery rider, a rider providing for the Shoreham settlement and a rider
providing for the RICO Credits (credits to the bills of customers as a result of
the settlement by LILCO of a RICO action in connection with the construction and
completion of nuclear generating facilities).

The LIPA Act requires LIPA to make PILOTs for certain New York State and local
revenue taxes which would otherwise have been imposed on LILCO. The PILOT
payments recovery rider allows for LIPA's rate adjustments to accommodate the
PILOTs.

For a further discussion on the Shoreham tax settlement see Note 13.

Note 6. Nine Mile Point Nuclear Power Station, Unit 2 ("NMP2")

As a result of the Merger, LIPA acquired an undivided 18% interest in NMP2,
located in Scriba, New York which is operated by Niagara Mohawk Power
Corporation ("NMPC"). The owners of NMP2 and their respective percentage
ownership are as follows: LIPA (18%), NMPC (41%), New York State Electric & Gas
Corporation ("NYSEG") (18%), Rochester Gas Electric Corporation ("RG&E") (14%)
and Central Hudson Gas & Electric Corporation (9%). LIPA's share of the rated
capability is approximately 205 MW. LIPA's net utility plant investment,
excluding nuclear fuel, was approximately $650 million at December 31, 1998,
$689 million at March 31, 1998 and $715 million at December 31, 1996. The
accumulated provision for depreciation, excluding decommissioning costs, was
approximately $13 million and $196 million at December 31, 1998 and March 31,
1998, respectively, and $169 million at December 31, 1996. The provision for
accumulated depreciation was re-established at zero on May 28, 1998, pursuant to
the Merger. Generation from NMP2 and operating expenses incurred by NMP2 are
shared in the same proportions as the cotenant's respective ownership interest.
LIPA is required to provide its share of financing for any capital additions to
NMP2. Nuclear fuel costs associated with NMP2 are being amortized on the basis
of the quantity of heat produced for the generation of electricity.

NMPC has contracted with the United States Department of Energy for the disposal
of spent nuclear fuel. LIPA reimburses NMPC for its 18% share of the cost under
the contact at a rate of $1.00 per megawatt hour of net generation less a factor
to account for transmission line losses.

Nuclear Plant Decommissioning

NMPC expects to commence the decommissioning of NMP2 in 2026, shortly after the
cessation of plant operations, using a method which provides for the removal of
all equipment and structures and the release of the property for unrestricted
use. LIPA's share of decommissioning costs, based upon a "Site-Specific" 1995
study (1995 study), is estimated to be $407 million in 2026 dollars ($161
million in 1998 dollars using a 3.5% escalation factor). LIPA's share of the
estimated decommissioning costs is currently being provided for in electric
rates and is being charged to operations as depreciation expense over the
service life of NMP2. The amount of decommissioning costs recorded as
depreciation expense for the seven months ended December 31, 1998 totaled $3.9
million, for the two months ended May 28, 1998 totaled $0.4 million, for the
year ended March 31, 1998 and the three months ended March 31, 1997, totaled
$2.2 million and $0.5 million, respectively, and $3.9 million for the year ended
December 31, 1996. The accumulated decommissioning costs collected in rates
through December 31, 1998, March 31, 1998 and December 31, 1996 amounted to
$20.2 million, $18.3 million and $15.6 million, respectively.

LIPA has acquired external trust funds established for the decommissioning of
the contaminated portion of the NMP2 plant. It is currently estimated that the
cost to decommission the contaminated portion of the plant will be approximately
76% of the total decommissioning costs. These funds comply with regulations
issued by the NRC and the FERC governing the funding of nuclear plant
decommissioning costs. LIPA's policy is to fund these trusts at least annually.
As of December 31, 1998, the balance in these funds, including reinvested net
earnings, was approximately $19 million. These amounts are included in
Nonutility Property and Other Investments. The trust fund investments consist of
U.S. Treasury debt securities and cash equivalents. The carrying amounts of
these investments approximate fair market value.

Reference is made to Note 3 under the subcaption "Recent Accounting
Pronouncements" for details of the proposed changes in accounting for nuclear
decommissioning costs.

In 1996, NMPC and RG&E announced plans to establish a joint nuclear operating
company to be known as New York Nuclear Operating Company ("NYNOC"). NYNOC was
envisioned to assume full responsibility for operation of all nuclear plants in
New York. In 1997, NYPA, Con Edison, Niagara Mohawk and Rochester Gas and
Electric Corporation, the four utilities operating nuclear generating facilities
in New York State, executed a joint announcement which expressed their desire to
move forward with plans to form NYNOC, and stated that the four utilities will
initiate the steps to assure that NYNOC will have the necessary leadership,
personnel and structure to operate the six nuclear units now operated
independently by such utilities. The joint announcement also stated that during
the transition phase, while necessary governmental approvals are sought, the
utilities would continue with and add to the cooperative initiatives the
companies have already begun. NYNOC, a limited liability company, would operate
the six nuclear plants currently operated by the four entities to achieve
economies of scale and increase cost effectiveness. The plants would continue to
be owned, and the output of the plants marketed, by the respective owners of the
plants. It is contemplated that NYNOC would become the operator under the
plants' NRC operating licenses, while other aspects of the NRC licenses would
remain with the owners of the plants. It is uncertain what effect Niagara
Mohawk's participation in such an arrangement will have on LIPA; nor can LIPA
predict the effect on such an arrangement of the auction proposal in the staff
report.

On or about June 15, 1998, NYSEG, one of the owners of the Nine Mile 2 Plant,
commenced an action against NMPC (which is the operator of the Nine Mile 2
Plant) in Supreme Court of the State of New York, Tompkins County, demanding,
among other things, judgment to: (i) enjoin NMPC from transferring operating
responsibility of the Nine Mile 2 Plant to NYNOC; and (ii) declare that NMPC may
not transfer its operational responsibility for the Nine Mile 2 Plant to NYNOC
without NYSE&G's consent. LIPA can make no prediction as to the outcome of this
litigation.

NMPC and NYSE&G have announced that they plan to pursue the sale of their
nuclear assets including its interest in NMP2. LIPA is reviewing its rights and
remedies under the agreements governing its 18% interest in NMP2. LIPA has not
received an offer to purchase its 18% interest in NMP2 and is not pursuing a
sale at this time.

On August 27, 1997, the PSC Staff ("Staff") issued a "Notice Soliciting Comments
on Nuclear Generation" requesting comments and alternative approaches by
interested parties on a "Staff Report on Nuclear Generation" ("Nuclear Report").
The Nuclear Report concludes that nuclear generation along with non-nuclear
generation facilities, should be subject to the discipline of market-based
pricing.

On March 20, 1998, the PSC initiated a proceeding to examine a number of issues
raised by the Nuclear Report and the comments received in response to it. In
reviewing the Nuclear Report and parties' comments, the PSC: (a) adopted as a
rebuttable presumption the premise that nuclear power should be priced on a
market basis to the same degree as power from other sources, with parties
challenging that premise having to bear a substantial burden of persuasion; (b)
characterized the proposals in the Staff paper as by and large consistent in
concept with the PSC's goal of a competitive, market-based electricity industry;
(c) questioned PSC Staff's position that would leave funding and other
decommissioning responsibilities with the sellers of nuclear power interests;
and, (d) indicated interest in the potential for the NYNOC to benefit customers
through efficiency gains and directed pursuit of that matter in this nuclear
generating proceeding or separately upon the filing of a formal NYNOC proposal.
The proceeding is expected to be completed in 1999.

The NRC issued a policy statement on the Restructuring and Economic Deregulation
of the Electric Utility Industry ("Policy Statement") in 1997. The Policy
Statement addresses NRC's concerns about the adequacy of decommissioning funds
and about the potential impact on operational safety and reserves to the NRC the
right, in highly unusual situations where adequate protection of public health
and safety would be compromised, to consider imposing joint and several
liability on minority co-owners when one or more co-owners have defaulted on
their contractual obligations. On December 28, 1998, the NRC announced
commencement of a rulemaking proceeding initiated by a group of utilities which
are non-operating joint owners of nuclear plants. These utilities request that
the enforcement provisions of the NRC regulations be amended to clarify NRC
policy regarding the potential liability of joint owners if other joint owners
become financially incapable of bearing their share of the burden for safe
operation or decommissioning of a nuclear power plant. On March 22, 1999, the
Authority filed comments in support of the rule proposed by the group of
utilities. In addition to the above Policy Statement, the NRC is proposing to
amend its regulations on decommissioning funding to reflect conditions expected
from deregulation of the electric power industry. LIPA is unable to predict how
such increased stringency may affect the results of operations or financial
condition of the Nine Mile 2 Plant.

On July 5, 1998, the Nine Mile 2 Plant completed its sixth refueling outage,
which commenced on May 2, 1998. It is scheduled to commence its seventh
refueling outage in March 2000.

Radioactive Waste

NMPC has contracted with the U.S. Department of Energy ("DOE") for disposal of
high-level radioactive waste ("spent fuel") from the Nine Mile 2 Plant. Despite
a court order reaffirming the DOE's obligation to accept spent nuclear fuel by
January 31, 1998, the DOE has forecasted the start of operations of its
high-level radioactive waste repository to be no earlier than 2010. LIPA has
been advised by NMPC that the Nine Mile 2 Plant spent fuel storage pool has a
capacity for spent fuel that is adequate until 2012. If DOE schedule slippage
should occur, the storage for NMP2 spent fuel, either at the plant or some
alternative location, may be required.

Nuclear Plant Insurance

NMPC procures public liability and property insurance for NMP2, and LIPA
reimburses NMPC for its 18% share of those costs.

The Price-Anderson Amendments Act mandates that nuclear power secure financial
protection in the event of a nuclear accident. This protection must consist of
two levels. The primary level provides liability insurance coverage of $200
million (the maximum amount available) in the event of a nuclear accident. If
claims exceed that amount, a second level of protection is provided through a
retrospective assessment of all licensed operating reactors. Currently, this
"secondary financial protection" subjects each of the 108 presently licensed
nuclear reactors in the United States to a retrospective assessment of up to
$88.1 million for each nuclear incident, payable at a rate not to exceed $10
million per year. LIPA's interest in NMP2 could expose it to a maximum potential
loss of $15.9 million, per incident, through assessments of up to $1.8 million
per year in the event of a serious nuclear accident at NMP2 or another licensed
U.S. commercial nuclear reactor. These assessments are subject to periodic
inflation indexing and to a 5% surcharge if funds prove insufficient to pay
claims.

NMPC has also procured $500 million primary nuclear property insurance with the
Nuclear Insurance Pools and approximately $2.3 billion of additional protection
(including decontamination costs) in excess of the primary layer through Nuclear
Electric Insurance Limited (NEIL). Each member of NEIL, including LIPA, is also
subject to retrospective premium adjustments in the event losses exceed
accumulated reserves. For its share of NMP2, LIPA could be assessed up to
approximately $1.6 million per loss. This level of insurance is in excess of the
NRC required minimum of $1.06 billion of coverage.

LIPA has obtained insurance coverage from NEIL for the extra expense incurred in
purchasing replacement power during prolonged accidental outages. Under this
program, should losses exceed the accumulated reserves of NEIL, each member,
including LIPA, would be liable for its share of deficiency. LIPA's maximum
liability per incident under the replacement power coverage, in the event of a
deficiency, is approximately $700,000.

The NRC has notified all utilities operating nuclear power plants that they are
required to inform the NRC of steps they are taking to see that computer systems
will function properly by the year 2000. In connection therewith, each such
utility was required to submit a written indication of, among other things,
whether or not they are pursuing and continuing to pursue a plan to solve their
Year 2000 issue, such as,

Note 7. Debt

Note Payable to the Authority

The debt of LIPA consists of certain debt assumed as of result of the Merger,
titled Long-Term Debt, a Note payable to the Authority, and amounts due to the
Authority for advances for the day-to-day operations of LIPA. The note payable
to the Authority represents the proceeds from the sale of Authority bonds which
were then transferred to LIPA in exchange for a promissory note. Such proceeds
were used by LIPA to finance the Merger, and to refinance certain of the assumed
debt as part of the Merger. The initial borrowing under this promissory note was
approximately $6.7 billion. As of December 31, 1998, the balance owed to the
Authority was approximately $5.4 billion. This promissory note transferred to
the Authority all of LIPA's right, title and interest in and to the revenue it
generates from the operation of the transmission and distribution system,
including the right to collect and receive that revenue. Therefore, cash
receipts from customers are collected by the Authority thereby reducing the note
payable to the Authority. The note payable to the Authority bears interest at a
rate equal to the weighted average interest rate on the bonds issued by the
Authority, approximately 4.71% at December 31, 1998.

Bonds issued by the Authority provided the funds to loan to LIPA. The Authority
bonds outstanding at December 31, 1998, consist of:

                                                                (in thousands)

Interest Rate Swaps

The Authority has entered into interest rate swap agreements to reduce the
impact of changes in interest rates on certain variable rate long-term debt of
the Authority. At December 31, 1998, the Authority had interest rate swap
agreements outstanding having a total notional amount of $150 million and $100
million, respectively. These agreements effectively change the Authority's
interest rate exposure on its $250 million variable rate notes due 2025 to a
fixed rate of 4.208 percent. The interest rate swap

Notes to Financial Statements
--------------------------------------------------------------------------------

agreements mature at the time the related notes mature with optional earlier
termination at the Authority's discretion. The Authority is exposed to credit
loss in the event of nonperformance by the other parties to the interest rate
swap agreements. However, the Authority does not anticipate nonperformance by
the counterparties.

Due to the Authority

All cash receipts from customers are collected by the Authority and are used to
repay the Note Payable to the Authority. Operating expenditures of LIPA are paid
by the Authority, and are recorded by LIPA as a loan-Due to the Authority. The
balance at December 31, 1998, totaled approximately $927 million. The interest
rate on this loan is equal to that on the Note Payable to the Authority.

Long Term Debt

Long Term Debt represents debt of LILCO assumed by LIPA as part of the Merger,
and consisted of $1.186 billion of G&R bonds, which were defeased by LIPA
immediately upon the closing of the Merger, debentures totaling $2.2 billion,
and tax exempt debt of $916 million. As part of the Merger, KeySpan and LIPA
executed Promissory Notes whereby KeySpan is obligated to LIPA for approximately
$1.048 billion of the assumed debt (the "Promissory Notes"). KeySpan is also
required to pay LIPA principal and interest on the Promissory Notes 30 days in
advance of the date amounts are due to bond holders. At December 31, 1998, the
balance of the Promissory Notes between KeySpan and LIPA totaled $1.045 billion
of which $398 million will be collected in 1999.

The tax exempt debt assumed by LIPA were notes issued by LILCO to the New York
State Research and Development Authority ("NYSERDA") to secure tax-exempt
Industrial Development Revenue Bonds, Pollution Control Revenue Bonds ("PCRBs"),
and Electric Facilities Revenue Bonds ("EFRBs") issued by NYSERDA.

Letters of Credit

The 1995, 1994 and 1993 EFRBs and the 1985 PCRBs are supported by letters of
credit pursuant to which a letter of credit bank has agreed to pay the
principal, interest and premium, if applicable, in the aggregate, up to $326
million in the event of default. Subsequent to December 31, 1998, EFRBs and
PCRBs were converted to fixed rate securities and LIPA cancelled the letters of
credit.

Bond Defeasance/Refundings

A portion of the proceeds of the Authority's Electric System General Revenue
Bonds and Subordinated Bonds (which includes fixed and variable rate debt) were
used to refund all the General and Refunding Bonds, certain Debentures and
certain NYSERDA Notes issued by LILCO that were assumed by LIPA as a result of
the Merger. The purpose of these refundings was to achieve debt service savings.

General and Refunding Bonds

On May 29, 1998, LIPA refunded all the G&R Bonds totaling $1.186 billion by
depositing $1.190 billion in an irrevocable escrow deposit account to be
invested in the direct obligations of the United States of America. The maturing
principal of and interest on these obligations were sufficient to pay the
principal and interest on the G&R Bonds which were redeemed on June 29, 1998.

The Authority will realize gross debt service savings from this refunding of
approximately $588 million over the life of the bonds. The refunding produced an
economic gain (the present value of the debt service savings) of approximately
$576 million.

Debentures

In October 1998, LIPA commenced a tender offer for its 7.30% Debentures Due
2000, 6.25% Debentures Due 2001, 7.05% Debentures Due 2003, 7.00% Debentures Due
2004, 7.125% Debentures Due 2005 and 9.00% Debentures Due 2022 (collectively,
the "Debentures"). The tender offers for the Debentures expired in November, and
LIPA purchased an aggregate principal amount of Debentures including accrued
interest in the amount of $1.13 billion pursuant to the tender offers. Payment
for Debentures purchased pursuant to the tender offers was made from the sale of
$1.31 billion Electric System General Revenue Bonds, Series 1998B (the
"Refinancing Bonds") of the Authority which closed in November. Under the terms
of the financing agreement dated as of May 1, 1998, between LIPA and the
Authority, a portion of the proceeds from the sale of the Refinancing Bonds were
advanced to LIPA to fund payment for the tendered Debentures.

In October 1998, LIPA sent a notice of redemption to the holders of its 7.50%
Debentures Due 2007 calling for redemption in November of all such debentures at
a redemption price equal to 103.54% of the $142 million aggregate principal
amount outstanding. In addition, LIPA sent a notice of redemption to the holders
of its 8.90% Debentures Due 2019 calling for redemption in November of all such
debentures at a redemption price equal to 105.94% of the $420 million aggregate
principal amount outstanding.

As a result of the refundings described above, the Authority will realize gross
debt service savings of approximately $547 million over the life of the bonds.
The refunding produced an economic gain (the present value of the debt service
savings) of approximately $376 million.

NYSERDAs

The Authority deposited $379 million in an irrevocable escrow deposit account to
be invested in the direct obligations of the United States of America. The
maturing Principal of and interest on such securities will be sufficient to pay
the principal, interest and applicable call premium on the following issues of
NYSERDA Notes: $11.9 million Series 1985A, $50 million Series 1989A, $15 million
Series 1989B, $26 million Series 1990A, $73 million Series 1991A, $50 million
Series 1992A, $36.5 million Series 1992B, $50 million Series 1992C and $22
million Series 1992D, (collectively, the "Refunded NYSERDA Notes").

--------------------------------------------------------------------------------

As a result of the refunding and the deposit with the Escrow Agent, the Refunded
NYSERDA Notes are deemed to have been paid, and they cease to be a liability of
LIPA. Accordingly, the Refunded NYSERDA Notes (and the related deposit with the
Escrow Agent) are excluded from the Balance Sheet. The Authority will realize
gross debt service savings from this refunding of approximately $287 million
over the life of the bonds. The refunding produced an economic gain (the present
value of the debt service savings) of approximately $66 million.

In November 1998, LIPA sent a notice of redemption to the holders of its 1982
NYSERDA Notes calling for redemption in December of all such NYSERDA notes at a
redemption price equal to the $17.2 million aggregate principal amount
outstanding.

The Authority will realize gross debt service savings from the refunding of
approximately $14.9 million over the life of the bonds. The refunding produced
an economic gain (the present value of the debt service savings) of
approximately $6.5 million.

Deferred Amortization

A debt refinancing charge of $61.9 million resulted from the transactions
described above primarily because of the difference between the amounts paid for
refundings, including amounts deposited with the Escrow Agent, and the carrying
amount of the G&R Bonds, Debentures and NYSERDA Notes. In accordance with the
provisions of GASB No. 23, the $61.9 million has been deferred and is shown in
the Balance Sheet as Deferred Amortization within long term debt and is being
amortized.

LILCO had tax credit carryforwards of approximately $189 million at March 31,
1998. The carryforward credits were comprised of investment tax credits ("ITC")
carryforwards, net of the 35% reduction required by the Tax Reform Act of 1986,
totaling approximately $30 million, research and development ("R&D") credits
totaling approximately $9 million, and alternative minimum tax ("AMT") credits
of approximately $150 million.

In May 1998, as a result of the Merger, LILCO recognized a net federal income
tax liability of approximately $70 million, after the utilization of all of the
company's ITC and R&D credit carryforwards of approximately $39 million and the
utilization of AMT credits of approximately $16 million.

In May 1998, LILCO reached a final settlement with the Internal Revenue Service
on its federal income tax returns for the years 1981 through 1989. The
settlement provided for the payment of taxes and

interest of approximately $9 million and $35 million, respectively, which LILCO
paid. LILCO had previously provided reserves adequate to pay such taxes and
interest.

Note 10. Retirement Benefit Plans

LILCO

Pension Plans

LILCO maintained a defined benefit pension plan which covered substantially all
employees (Primary Plan), a supplemental plan which covered officers and certain
key executives (Supplemental Plan) and a retirement plan which covered the Board
of Directors (Directors' Plan). LILCO also maintained 401(k) plans for its union
and non-union employees to which it did not contribute.

Primary Plan

LILCO's funding policy was to contribute annually to the Primary Plan a minimum
amount consistent with the requirements of the Employees Retirement Income
Security Act of 1974, plus such additional amounts, if any, as LILCO determined
to be appropriate. Pension benefits were based upon years of participation in
the Primary Plan and compensation.

The increase in the present value of the accrued benefit at March 31, 1998,
compared to December 31, 1996, was due to the change in the discount rate from
7.25% to 7.00% and the use of updated actuarial assumptions relating to
mortality.

The Primary Plan assets at fair value included cash, cash equivalents, group
annuity contracts, bonds and equity securities.

In 1993, the PSC issued an Order which addressed the accounting and ratemaking
treatment of pension costs in accordance with SFAS No. 87, "Employers'
Accounting for Pensions." Under the Order, LILCO was required to recognize any
deferred net gains or losses over a ten-year period rather than using the
corridor approach method. LILCO believed that this method of accounting for
financial reporting purposes resulted in a better matching of revenues and
LILCO's pension cost. LILCO deferred the differences between pension rate
allowances and pension expense under the Order. In addition, the PSC required
LILCO to measure and pay a carrying charge on amounts in excess of the pension
rate allowance and the annual pension contributions contributed into the pension
fund.

In addition, effective December 1, 1997, LILCO deferred the difference between
the sum of gas pension and gas postretirement benefit costs other than pension
and the amounts provided for in rates, to the extent that such differences were
in excess of or below three percent of LILCO's pretax net income from gas
operations. Such excess was transferred to a gas balancing account.

Supplemental Plan 

The Supplemental Plan provided supplemental death and retirement benefits for
officers and other key executives without contribution by those employees. The
Supplemental Plan was a non-qualified plan under the Internal Revenue Code. For
the year ended March 31, 1998, LILCO recorded a charge of approximately $31
million relating to certain benefits earned by its officers relating to the
termination of their annuity benefits earned through the supplemental retirement
plan and other executive retirement benefits. These charges, the cost of which
were borne by LILCO's shareowners, resulted from provisions of the officers'
employment contracts, including employment contract of LILCO's Chairman, and the
pending transactions with LIPA and KeySpan which affected the timing of when
these costs were recorded. The provision for plan benefits totaled approximately
$200,000 for the period April 1, 1998 through May 28, 1998, $700,000 for the
three months ended March 31, 1997 and $2.7 million for the year ended December
31, 1996.

Directors' Plan

The Directors' Plan provided benefits to directors who were not officers of
LILCO. Directors who had served in the capacity for more than five years
qualified as participants under the plan. The Directors' Plan was a
non-qualified plan under the Internal Revenue Code. The provision for retirement
benefits, which were unfunded, totaled approximately $245,000 for the period
April 1, 1998 through May 28, 1998, $132,000 for the year ended March 31, 1998,
$34,000 for the three months ended March 31, 1997 and $127,000 for the year
ended December 31, 1996.

Postretirement Benefits Other Than Pensions

In addition to providing pension benefits, LILCO provided certain medical and
life insurance benefits to retired employees. Substantially all of LILCO's
employees became eligible for such benefits if they had reached retirement age
after working for LILCO for a minimum of five years. These and similar benefits
for active employees were provided by LILCO or by insurance companies whose
premiums are based on the benefits paid during the year. Effective January 1,
1993, LILCO adopted the provisions of SFAS No. 106, "Employers' Accounting for
Postretirement Benefits Other Than Pensions," which required LILCO to recognize
the expected cost of providing postretirement benefits when employee services
were rendered rather than when paid. As a result, LILCO, in 1993, recorded an
accumulated postretirement benefit obligation and a corresponding regulatory
asset of approximately $376 million.

The PSC required LILCO to defer as a regulatory asset the difference between
postretirement benefit expense recorded for accounting purposes in accordance
with SFAS No. 106 and the postretirement benefit expense reflected in rates. The
ongoing annual postretirement benefit expense was phased into and fully
reflected in rates which began December 1, 1996, with the accumulated regulatory
asset to be recovered in rates over a 15-year period, beginning December 1,
1997. In addition, LILCO was required to recognize any deferred net gains or
losses over a ten-year period.

In addition, effective December 1, 1997, LILCO deferred the difference between
the sum of gas pension and gas postretirement benefit costs other than pension
and the amounts provided for through rates, to the extent that such differences
were in excess of or below three percent of LILCO's pretax net income from gas
operations. Such excess was transferred to a gas balancing account.

In 1994, LILCO maintained Voluntary Employee's Beneficiary Association trusts
for union and non-union employees for the funding of incremental costs collected
in rates for postretirement benefits. LILCO funded the trusts with approximately
$21 million for the year ended March 31, 1998, $5 million for the three months
ended March 31, 1997 and $18 million for the year ended December 31, 1996. In
May 1998, LILCO contributed an additional $250 million into the trusts,
representing obligations related to the electric business unit employees. LILCO
secured a bridge loan to fund these trusts.

Accumulated postretirement benefit obligation other than pensions at March 31,
1998, and December 31, 1996 was as follows:

Note 11. The Class Settlement

The Class Settlement, which became effective in June 1989, resolved a civil
lawsuit against LILCO brought under the federal Racketeer Influenced and Corrupt
Organizations Act. The lawsuit, which the Class Settlement resolved, had alleged
that LILCO made inadequate disclosures before the PSC concerning the
construction and completion of nuclear generating facilities.

The Class Settlement continues to provide the electric rate payers with rate
reductions which will total $390 million over a ten-year period which began on
June 1, 1990. As of December 31, 1998, the remaining rate reductions, which are
being reflected as adjustments to customer's bills, total approximately $85
million and consists of approximately $25 million for the five-month period
beginning January 1, 1999 and $60 million for the 12-month period beginning June
1, 1999. Such reductions to LIPA's customer's are reimbursed by KeySpan, in
accordance with the Merger Agreement.

Note 12. The 1989 Settlement

In February 1989, LILCO and the State of New York entered into the 1989
Settlement resolving certain issues relating to LILCO and provided for the
transfer of Shoreham to the Authority. The Settlement also included provisions
for the decommissioning of Shoreham and the recovery by the Authority of the
costs of decommissioning from LILCO, and in turn the recovery of those costs by
LILCO from customers. In February 1992, LILCO transferred ownership of Shoreham
to the Authority. In May 1995, the NRC terminated the Authority's
possession-only license for Shoreham which signified the NRC's approval that
decommissioning was complete and that the site was suitable for unrestricted
use.

Upon the effectiveness of the 1989 Settlement, in June 1989, LILCO recorded the
FRA on its Balance Sheet and the retirement of its investment of approximately
$4.2 billion, principally in Shoreham.

Pursuant to the 1989 Settlement, LILCO was required to reimburse the Authority
for all of its costs associated with the decommissioning of Shoreham. The PSC
had determined that all costs associated with Shoreham which were prudently
incurred by LILCO subsequent to the effectiveness of the 1989 Settlement were
decommissioning costs. The RMA provided for the recovery of such costs through
electric rates over the balance of a forty-year period ending 2029. At March 31,
1998, Shoreham post-settlement costs totaled approximately $1.2 billion,
consisting of $587 million of property taxes and PILOTS, and $568 million of
decommissioning costs, fuel disposal costs and all other costs incurred at
Shoreham after June 30, 1989.

Legal Proceedings

Shoreham Tax Matters

Through November 1992, Suffolk County and the following Suffolk County political
subdivisions (collectively, the "Suffolk Taxing Jurisdictions"), the Town of
Brookhaven, Shoreham-Wading River Central School District, Wading River Fire
District and the Shoreham-Wading River Library District (which was succeeded by
the North Shore Library District), levied and received real estate taxes from
LILCO on the Shoreham plant. When the Authority acquired the Shoreham plant in
February 1992, it was obligated pursuant to the LIPA Act to make PILOTs on the
Shoreham plant beginning in December 1992. As part of the agreement between
LILCO and the Authority providing for the transfer of Shoreham to the Authority,
LILCO agreed to fund these payments. Prior to the Merger, LILCO charged rates
sufficient to make these payments to the Authority. Both LILCO and the Authority
contested the assessments, claiming the Shoreham plant was overassessed. To
date, the Authority has made such payments, in whole or in part, pursuant to
interim PILOT agreements and collected the costs thereof pursuant to the PILOTs
rider which is part of LIPA's rates.

On March 26, 1997, a judgment was entered in the Supreme Court, State of New
York, Suffolk County, on behalf of LILCO against the Suffolk Taxing
Jurisdictions ordering them to refund to LILCO property tax overpayments
(resulting from over-assessments of Shoreham) in an amount exceeding $868
million, including interest as of the date of the judgement. In addition, the
judgment provides for the payment of post-judgment interest (the "Shoreham
Property Tax Litigation"). The Court also determined that the Shoreham plant had
a value of nearly zero during the period the Authority has owned Shoreham. This
judgment was unanimously affirmed by the Appellate Division of the State of New
York on July 13, 1998. Certain of the Suffolk Taxing Jurisdictions sought to
appeal this judgment to the New York State Court of Appeals. Their applications
were unanimously denied by the Appellate Division. New applications for leave to
appeal were made to the Court of Appeals. On January 19, 1999, the Court of
Appeals denied the motions. There is no further review in the New York State
court system.

The Authority had proposed a settlement agreement with the Suffolk Taxing
Jurisdictions and Nassau County. The proposed settlement agreement would, among
other things, cause the Authority: (i) not to enforce the judgment in favor of
LILCO; and (ii) not to make any claim for a refund of what the

--------------------------------------------------------------------------------

Authority believes is an overpayment of PILOT's, in exchange for the payment by
the Suffolk Taxing Jurisdictions to the Authority of $625 million.

On February 1, 1999, a lawsuit was filed in the Supreme Court of the State of
New York, Nassau County, by the Association for a Better Long Island against the
Authority and LIPA. This lawsuit seeks: (i) to require the Authority to collect
the full amount of the judgment obtained by the Authority in the Shoreham
Property Tax Litigation as well as certain overpaid PILOTs; and (ii) to declare
that the offer of the Authority to settle the Shoreham Property Tax Litigation
is void and legally unenforceable. No assurance can be given as to the method,
amount (if any) or timing of any recovery by the Authority related to the
Shoreham Property Tax Litigation.

The proposed settlement agreement with the Suffolk Taxing Jurisdictions was not
accepted and on March 1, 1999, the Authority withdrew its offer to settle the
Shoreham Property Tax Litigation including claims related to the Authority's
overpayment of PILOTs on the Shoreham plant for $625 million and indicated that
any settlement would have to be at a higher amount. On that date, the Authority
also demanded that the Suffolk Taxing Jurisdictions pay refunds of real estate
taxes in the amount of approximately $784 million consisting of: (i) refunds and
interest due as of the entry of the judgment on March 26, 1997, for the period
from and after January 15, 1987, (the effective date of the LIPA Act), of
approximately $675 million; and (ii) accrued post-judgment interest in the
amount of approximately $109 million. Post-judgment interest will continue to
accrue until the judgment is satisfied.

On September 15, 1998, Suffolk County filed an action against the Authority in
the Supreme Court of the State of New York, Suffolk County seeking to enjoin the
Authority from recovering tax refunds based upon the over-assessment of the
Shoreham nuclear plant. The action claims that the Authority does not have the
right to recover property taxes previously assessed against LILCO for tax years
1984-1985 through 1991-1992. On March 19, 1999, the Court ruled that the
Authority was not entitled to collect any refund of property taxes assessed
against the Shoreham plant. In addition, the court stated that the Authority has
a duty to discontinue and abandon all proceedings which seek the repayment of
all or part of the taxes assessed against the Shoreham plant. The Authority
intends to appeal this decision. The Authority does not believe that an adverse
decision in this litigation will have a material adverse effect on the
Authority's or LIPA's financial condition. Further, the court stated that under
a ruling of the State Court of Appeals, the Authority is not prohibited from
seeking refunds of PILOTs paid on over-assessments of the Shoreham plant.

The New York State Court of Appeals in a separate case has ruled that the Act
does not prohibit the Authority from seeking refunds plus interest if it has
overpaid PILOTs based on an over-assessment of Shoreham. The Authority has made
PILOT payments of approximately $345 million which it believes were based on
such an over-assessment. On February 24, 1999, the Authority filed an action
against the Suffolk Taxing Jurisdictions in the Supreme Court of the State of
New York, Nassau County seeking a judgment in an amount equal to the total
amount of PILOTs overpaid by the Authority, plus interest.

On March 23, 1999, the Shoreham Wading River Central School District filed an
action against the Authority in the Supreme Court of the State of New York,
County of Nassau seeking an order directing the Authority to pay approximately
$6.4 million of PILOTs which the plaintiff alleges are due and owing and
approximately $24.6 million of PILOTs which the plaintiff alleges is the
cumulative deficiency as of

June 1, 1998. The Authority does not believe that an adverse decision in this
litigation will have a material adverse effect on the Authority's or LIPA's
financial condition.

Merger Matters

LIPA has been named as a nominal defendant in a derivative suit pending in the
United States District Court for the Eastern District of New York entitled
Sylvester v. Catacosinos, et al. A motion to dismiss on behalf of LIPA was filed
on September 23, 1998 and argued on January 28, 1999. In addition, LIPA has been
named as a defendant in an action brought by the County of Suffolk that is
pending in New York State Supreme Court, Suffolk County, entitled County of
Suffolk v. KeySpan et al. The response date has been postponed until such time
as it is determined whether the action will be consolidated with a class action
pending in New York State Supreme Court, Nassau County, entitled In re KeySpan
Corporation Shareholder Litigation. Former officers and directors of LILCO also
have been named as defendants in each of these actions.

The complaints in the foregoing actions allege in substance that certain former
officers of LILCO received excessive compensation which totaled approximately
$67 million in connection with the closing of the Brooklyn Union merger with
LILCO and with the Authority's acquisition of the common stock of LILCO. The
Sylvester lawsuit seeks damages of an unspecified amount. The complaint brought
by the County of Suffolk seeks to make the defendants pay restitution, or
damages, of $67 million.

Because the cases are in an early state, at which no discovery has yet taken
place, LIPA cannot express an opinion as to the likelihood of any liability.
LIPA has notified KeySpan of its entitlement to indemnification pursuant to an
indemnification agreement dated June 26, 1997 for any losses LIPA suffers as a
result of these lawsuits. LIPA expects that KeySpan will honor the request for
indemnification. LIPA also understands that the Attorney General of the State of
New York is investigating the actions and statements of certain former officers
of LILCO in connection with such compensation.

On September 28, 1998, Suffolk County and the Towns of Huntington and Babylon
(collectively, the "Plaintiffs") brought a class action on behalf of themselves
and all electric utility ratepayers in Suffolk County (the "Ratepayers") against
the Authority, LIPA, KeySpan and others in the United States District Court for
the Eastern District of New York entitled County of Suffolk et al. v. Long
Island Power Authority, et al. (the "Huntington Lawsuit"). The Huntington
Lawsuit alleges that (i) LIPA and the Authority failed to refund alleged capital
gains directly to Ratepayers as a result of the Merger, unlawfully depriving
Ratepayers of their property under federal and state constitutional provisions
and (ii) LIPA failed to refund to Ratepayers certain deferred tax reserves
carried on LILCO's books at the time of the Merger, unjustly enriching KeySpan.

Based on these allegations, Plaintiffs are seeking judgments, among other
things: (i) awarding damages against KeySpan and LIPA for impairment of
contract, breach of contract and conversion; and (ii) declaring that KeySpan
holds the proceeds of the Merger attributable to the capital gains and the
deferred tax reserve in trust for the benefit of the Ratepayers and ordering
KeySpan to make a full accounting of such proceeds. LIPA believes that, although
the recovery sought by Plaintiffs could be material in amount, any such recovery
would not have a material financial impact on LIPA or its customers.

In an action commenced on May 26, 1998 (Schulz et al. v. New York State Public
Authorities Control Board et al., United States District Court, Northern
District of New York), plaintiff's complaint, in several claims for relief,
sought a judgment declaring, inter alia, the resolution of the PACB authorizing
the Authority to issue bonds to be null and void on State and federal
constitutional grounds and sought a temporary restraining order or preliminary
injunction prohibiting and enjoining the issuance of bonds. On May 27, 1998, the
District Court denied the plaintiff's request for a temporary restraining order
or preliminary injunction and dismissed the plaintiff's action on the ground
that the plaintiffs lack standing to assert the claims pleaded in the complaint.
On February 8, 1999, the United States Court of Appeals for the Second Circuit
affirmed the District Court's dismissal of the plaintiff's action.

On May 27, 1998, the Initiative for Competitive Energy (the "ICE") filed an
action in the Supreme Court of the State of New York, County of Suffolk, against
the Authority seeking, inter alia, an injunction enjoining the Authority from
selling bonds "whose purpose is to finance the proposed Shoreham Property Tax
Settlement, the Shoreham Rebates, Credits and Suffolk Surcharge." The action
further requested a judgment declaring invalid and directing the rescission of
the sale of such bonds. By decision dated October 7, 1998, the Supreme Court
dismissed the complaint and ruled in favor of the Authority on all issues. On
October 28, 1998, the ICE filed a notice of appeal.

In May 1995, eight participants of LILCO's Retirement Income Plan ("RIP") filed
a lawsuit against LILCO, the RIP and Robert X. Kelleher, the Plan Administrator,
in the United States District Court for the Eastern District of New York. In
January 1996, the Court ordered that this action be maintained as a class
action. This proceeding arose in connection with the plaintiff's withdrawal,
approximately 25 years ago, of contributions made to the RIP, thereby resulting
in a reduction of their pension benefits. On January 7, 1999, a settlement
agreement was filed with the Court providing for the payment of $7.75 million to
the plaintiffs. The Authority would be responsible for approximately $5.4
million. The settlement is subject to judicial review. Amended settlement papers
were filed on February 22, 1999 and a hearing date is scheduled for July 27,
1999.

In December 1997, Suffolk County brought a suit against the Authority and others
in the Supreme Court of the State of New York seeking a judgment, among other
things: (i) annulling and vacating the acceptance by the Authority of certain
conditions contained in the July 1997 PACB resolution approving the Authority's
acquisition of LILCO and related transactions; (ii) declaring that all or any
actions taken by the Authority to implement or carry out the PACB conditions are
null and void; and (iii) directing that the Authority take no further action to
acquire the stock or assets of LILCO unless and until such acquisition has been
approved by the PACB in the manner approved by law. A decision was rendered in
March 1998 which held for the Authority on all substantive issues. Suffolk
County filed a notice of appeal to the Appellate Division of the State of New
York.

LIPA is involved in various legal proceedings which are routine litigation
matters incidental to the conduct of its business. In the judgment of the
Authority and LIPA, these matters will not individually or in the aggregate,
have a material adverse effect on the financial position, results of operations
or cash flows of LIPA.

Environmental

In connection with the Merger, KeySpan and LIPA entered into Liabilities
Undertaking and Indemnification Agreements which, when taken together, provide,
generally, that environmental liabilities will be divided between KeySpan and
LIPA on the basis of whether they relate to assets transferred to KeySpan or
retained by LIPA as part of the Merger. In addition, to clarify and supplement
these agreements, KeySpan and LIPA also entered into an agreement to allocate
between them certain liabilities, including environmental liabilities, arising
from events occurring prior to the Merger and relating to the business and
operations to be conducted by LIPA after the Merger (the "Retained Business")
and to the business and operations to be conducted by KeySpan after the Merger
(the "Transferred Business").

KeySpan is responsible for all liabilities arising from all manufactured gas
plant operations ("MGP Sites"), including those currently or formerly operated
by KeySpan or any of its predecessors, whether or not such MGP Sites related to
the Transferred Business or the Retained Business. In addition, KeySpan is
liable for all environmental liabilities traceable to the Transferred Business
and certain scheduled environmental liabilities. Environmental liabilities that
arise from the non-nuclear generating business may be recoverable by KeySpan as
part of the capacity charge under the PSA. LIPA is responsible for all
environmental liabilities traceable to the Retained Business and certain
scheduled environmental liabilities.

Environmental liabilities that exist as of the date of the Merger that are
untraceable, including untraceable liabilities that arise out of common and/or
shared services have been allocated 53.6% to LIPA and 46.4% to KeySpan.

Environmental Matters Retained by LIPA

Long Island Sound Transmission Cables. The Connecticut Department of
Environmental Protection ("DEP") and the DEC separately have issued
Administrative Consent Orders ("ACOs") in connection with releases of insulating
fluid from an electric transmission cable system located under the Long Island
Sound. The ACOs require the submission of a series of reports and studies
describing cable system condition, operation and repair practices, alternatives
for cable improvements or replacement, and environmental impacts associated with
prior leaks of fluid into the Long Island Sound. Compliance activities
associated with the ACOs are ongoing.

Simazine. Simazine is a commercially available herbicide manufactured by
Novartis that was used by LILCO as a defoliant until 1993 under the direction of
a New York State Certified Pesticide Applicator. Simazine contamination was
found in groundwater at one of the LIPA substations in 1997. LIPA is working
cooperatively with the Suffolk County Department of Health, the DEC and Novartis

this herbicide. The liability, if any, resulting from the use of this herbicide

operations.

Superfund Sites

Under Section 107(a) of the federal Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA", also commonly referred to as the
"Superfund Legislation"), parties who

generated or arranged for disposal of hazardous substances are liable for costs
incurred by the EPA in responding to a release or threat of release of the
hazardous substances.

Metal Bank. In December 1997, the EPA issued its Record of Decision ("ROD"), in
connection with the remediation of a licensed disposal site located in
Philadelphia, Pennsylvania, and operated by Metal Bank of America. In the ROD,
the EPA estimated that the present worth cost of the selected remedy for the
site is $17.3 million. In June 1998, the EPA issued a unilateral administrative
order to 13 PRPs, including LIPA, for the remedial design and for remedial
action at the site. LIPA can not predict with reasonable certainty the actual
cost of the selected remedy, who will implement the remedy, or the cost, if any,
to LIPA. Under a PRP participation agreement, LIPA is responsible for 7.95% of
the costs associated with implementing the remedy. LIPA has recorded a liability
of $1.6 million representing its estimated share of the additional cost to
remediate this site.

PCB Treatment Inc. LILCO has also been named a PRP for disposal sites in Kansas
City, Kansas and Kansas City, Missouri. The two sites were used by a company
named PCB Treatment, Inc. from 1982 until 1987 for the storage, processing, and
treatment of electric equipment, oils and other materials containing PCBs.
According to the EPA, the buildings and certain soil areas outside the buildings
are contaminated with PCBs. Certain of the PRPs, including LILCO and several
other utilities, formed a group, signed a consent order, and have developed a
work plan for investigating environmental conditions at the site. The EPA
provided LILCO with documents indicating that LILCO was responsible for less
than 1% of the materials that were shipped to this site. LIPA is currently
unable to determine its share of the cost to remediate these sites.

Environmental Matters Which May Be Recoverable From LIPA By KeySpan Through
The PSA

Asharoken. In March 1996, the Village of Asharoken (the "Village") filed a
lawsuit against LILCO in the New York Supreme Court, Suffolk County
(Incorporated Village of Asharoken, New York, et al. v. Long Island Lighting
Company). The Village is seeking monetary damages and injunctive relief based
upon theories of negligence, gross negligence and nuisance in connection with
the LILCO design and construction of the Northport Power Plant which the Village
alleges upset the littoral drift, thereby causing beach erosion. In November
1996, the court decided LILCO's motion to dismiss the lawsuit, dismissing two of
the three causes of action. The court limited monetary damages on the surviving
continuous nuisance claim to three years prior to the commencement of the
action. The liability, if any, resulting from this proceeding cannot yet be
determined. However, LIPA does not believe that this proceeding will have a
material adverse effect on its financial position, cash flows or results of
operations.

Environmental Matters Which Are Currently Untraceable For Which LIPA Could Have
Responsibility

Other Superfund Sites. In connection with a lawsuit filed against LILCO and nine
other PRPs by the Town of Oyster Bay for indemnification for remediation and
investigation costs for a federal Superfund site in Syosset, New York, a
settlement agreement has been reached and is subject to court approval. If
approved, the settlement would not have a material adverse effect on LIPA's
financial position, cash flows or results of operations. In addition, LILCO was
notified by the Attorney General of the State of New York that it may be
responsible for the disposal of wastes and/or for the generation of hazardous
substances that may have been disposed of at the Blydenburgh Superfund site.
LILCO conducted a

search of its corporate records and did not locate any documents concerning
waste disposal practices associated with this landfill. Based on current
information, LIPA does not believe that this proceeding will have a material
adverse effect on its financial position, cash flows or results of operations.

DEC has notified LILCO, pursuant to the New York State superfund program, that
LIPA may be responsible for the disposal of hazardous substances at the
Huntington/East Northport Site, a municipal landfill property. The DEC
investigation is in its preliminary stages, and LIPA is currently unable to
determine its share, if any, of the costs to investigate and remediate this
site.

Other Matters

As a result of the Merger, LIPA has assumed contracts with numerous Independent
Power Producers ("IPPs") and the New York Power Authority ("NYPA") for electric
generating capacity. Under the terms of the agreement with NYPA, which will
expire in May 2014, LIPA may purchase up to 100% of the electric energy produced
at the NYPA facility located within LIPA's service territory at Holtsville, New
York. LIPA is required to reimburse NYPA for the minimum debt service payments
and to make fixed non-energy payments associated with operating and maintaining
the plant.

With respect to contracts entered into with the IPPs, LIPA is obligated to
purchase all the energy they make available to LIPA at prices that often exceed
current market prices. However, LIPA has no obligation to the IPPs it they fail
to deliver energy. For purposes of the table below, LIPA has assumed full
performance by the IPPs, as no event has occurred to suggest anything less than
full performance by these parties.

LIPA has also assumed a contract with NYPA for firm transmission ("wheeling")
capacity in connection with a transmission cable which was constructed, in part,
for the benefit of LIPA. In accordance with the provisions of this agreement,
which expires in 2020, LIPA is required to reimburse NYPA for debt service
payments and the cost of operating and maintaining the cables. The cost of such
contracts is included in electric fuel expense and is recoverable through rates.

Note 14. Related Party Transactions

LIPA, as owner of the transmission and distribution system and as party to the
Operating Agreements, conducts the electric business in the Service Area. The
Authority is responsible, however, for administering, monitoring and managing
the performance by all parties to the Operating Agreements.

The Authority and LIPA are also parties to an Administrative Services Agreement
which describes the terms and conditions under which the Authority provides
personnel, personnel-related services and other services necessary for LIPA to
provide electric service in the Service Area.

As compensation to the Authority for the services described above, the Authority
charges LIPA a monthly management fee equal to the costs incurred by the
Authority in order to perform its obligations under the agreements described
above. For the period May 29, 1998 to December 31, 1998, management fees charged
by the Authority amounted to approximately $10.5 million.

Long Island Lighting Company d/b/a LIPA
(a wholly-owned subsidiary of the Long Island Power Authority)

                           Supplementary Information
                              Impact of Year 2000

General. A portion of the computer hardware and software and embedded technology
(such as microcontrollers and microprocessors contained in equipment and
machinery) used by the Authority and LIPA, as well as KeySpan and the
subsidiaries of KeySpan that are parties to the MSA, EMA and PSA and others with
whom the foregoing have business arrangements, was not designed to recognize
calendar years after 1999 (the "Year 2000 Issue").

The Authority recently purchased new computer software to support certain
activities of LIPA and believes that these systems are Year 2000 ready.
Management also believes that, based on available information, it will be able
to manage its Year 2000 transition for systems and infrastructure, without any
material adverse effect on its business operations or financial prospects.
However, there can be no assurance that failure to resolve any issue relating to
such transition would not have a material adverse effect on LIPA. LIPA has had
continuing discussions with KeySpan, their largest vendor, who is responsible
for the management and operation of LIPA's transmission and distribution system,
and KeySpan indicates that they have evaluated the extent to which modifications
to computer software, hardware and databases will be necessary to accommodate
the year 2000.

KeySpan's computer applications are generally based on two digits and do require
additional programming to recognize the new millennium. A corporate-wide program
has been established by KeySpan and its subsidiaries. The program includes both
information technology ("IT") and non-IT systems. The critical non-IT systems
are generally in the areas of electric production, distribution, transmission,
gas distribution and communications. The readiness of suppliers and vendor
systems is also under review. The project is under the direction of KeySpan's
Year 2000 Program Office, chaired by the Vice President, Technology Operations
and Corporate Y2K Officer. Each of KeySpan's critical business processes is
being reviewed to: identify and inventory sub-components; assess for Year 2000
compliance; establish repair plans as necessary; and test in a Year 2000
environment. The inventory phase for the IT systems and non-IT systems is 100%
complete. The assessment phase is 100% complete for the IT systems, and over 90%
complete for non-IT systems. The assessment phase is expected to be complete by
July 1, 1999.

KeySpan's hardware, software and embedded systems are being tested and certified
to be Year 2000 compliant. Repair and testing to sustain operability is now 73%
complete for the IT systems and approximately 75% for the non-IT systems.
Components needed to support the critical business process and associated
business contingency plans are expected to be ready for the year 2000 by July 1,
1999.

KeySpan's vendors and business partners needed to support the critical business
processes of KeySpan are also being reviewed for their year 2000 compliance. At
this time, none of these vendors have indicated to Key Span that they will be
materially affected by the year 2000 problem.

Key-Span has analyzed each of the critical business processes to identify
possible Year 2000 risks. Each of KeySpan's critical businesses will be
certified by the responsible KeySpan officer as being Year 2000 ready. However,
the most reasonable likely worst case scenarios are also being identified.
Business operating procedures at KeySpan will be reviewed to ensure that risks
are minimized when entering the

--------------------------------------------------------------------------------

Year 2000 and other high risk dates. KeySpan is developing contingency plans to
address possible failure points in each critical business process.

While KeySpan must plan for the following worst case scenarios, management
believes that these events are improbable.

Loss of generating flexibility:

KeySpan's generation subsidiary receives gas delivery from multiple national and
international pipelines and, therefore the effects of a loss in any one pipeline
can be mitigated through the use of other pipelines. Complete loss of all the
supply lines is not considered a reasonable scenario. Nevertheless, the impact
of the loss of any one pipeline is dependent on temperature and vaporization
rate. The partial loss of gas supply will not affect KeySpan's ability to supply
electricity since many of the plants have the ability to operate on oil.

Loss of electric grid inter-connections/KeySpan operated electric distribution
facilities:

Electric utilities are physically connected on a regional basis to manage
electric load. This is often referred to as the regional grid. Presently,
KeySpan is working with other regional utilities to develop a coordinated
operating plan. Should there be an instability in the grid, KeySpan has the
ability to remove LIPA's operations from the grid, and operate independently.

Certain electric system components such as individual generating units,
transmission and distribution system facilities, and the electric energy
management system have the potential to malfunction due to Year 2000 problems.
KeySpan has inventoried electric system components and developed a plan to
certify mission critical processes as Year 2000 compliant. Contingency plans are
being developed, where appropriate, for loss of critical system elements.
KeySpan presently estimates that contingency plans regarding its electric
facilities should be completed by July 1999.

Loss of telecommunications:

KeySpan has a substantial dependency on many telecommunication systems and
services for both internal and external communications. External communications
with the public and the ability of customers to contact KeySpan in cases of
emergency response is essential. KeySpan intends to coordinate its emergency
response efforts with the offices of emergency management of the various local
governments within its service territory. Internally, there are a number of
critical processes in both the gas and electric operating areas that rely on
external communication providers. Contingency plans will address methods for
manually monitoring these functions. These contingency plans, KeySpan presently
estimates, should be finalized by July 1999.

In addition to the above, KeySpan is also planning for the following scenarios:
short-term reduction in system power generating capability; limitation of fuel
oil operation; reduction in quality of power output; loss of automated meter
reading; loss of ability to read, bill and collect; and loss of the purchasing/
materials management system.

KeySpan believes that, with modifications to existing software and conversions
to new hardware and software, the Year 2000 issue will not pose significant
operational problems for its computer systems. However, if such modifications
and conversions are not made, or are not completed on time, and contingency
plans fail the Year 2000 issue could have a material adverse impact on the
operations of LIPA.

LIPA's Contingency Plans
Long Island Lighting Company d/b/a LIPA
(a wholly-owned subsidiary of the Long Island Power Authority)

--------------------------------------------------------------------------------

In order to insure that the Year 2000 will have a minimal impact on the
operations of LIPA, LIPA is closely monitoring the initiatives and progress of
KeySpan's Year 2000 Program Office. In addition, LIPA is working with various
other governmental agencies to insure communication between LIPA and such other
governmental entities is uninterrupted.

Item 12. Security Ownership of Certain Beneficial Owners and Management

      The Authority owns 100% of the outstanding Common Stock of LIPA.

Item 13. Certain Relationships and Related Transactions

      On May 1, 1998, the Authority and LIPA entered into a financing agreement
(the "Financing Agreement") providing for their respective duties and
obligations relating to the financing and operation of the retail electric
business in the Service Area. Pursuant to the Financing Agreement, the Authority
has issued and will issue, among other things, all required debt necessary to
fund the LIPA/LILCO Merger, the debt necessary to finance the LIPA tender offer
for the Debentures and any debt necessary to fund improvements to the system.
The proceeds of such debt is treated as being loaned to LIPA (the "LIPA Loan")
which will repay such loans from the cash that the Authority receives from its
electric business. To secure the loans, LIPA has pledged its revenues to the
Authority which has, in turn, pledged such revenues as security for such debt.
At December 31, 1998, $5.4 billion was outstanding under the LIPA Loan. See Note
7 to Notes to Financial Statements.

      In addition to the LIPA Loan, LIPA's operating expenditures are paid for
by the Authority and LIPA records the amounts paid as a payable to the Authority
(this is necessary since the Authority collects all customer payments). At
December 31, 1998, the amount due to the Authority totaled approximately $856
million.

      On May 1, 1998, the Authority and LIPA entered into an administrative
services agreement (the "Administrative Services Agreement"). The term of the
Administrative Services Agreement commenced on May 1, 1998 and continues to
December 31, 2038. Thereafter, the agreement shall be renewed for successive
periods of 3 years upon mutual agreement of the parties. Pursuant to the
Administrative Services Agreement, the Authority provides personnel and
personnel services (including management, supervisory, payroll and otherwise)
necessary for LIPA to conduct its business. In addition, the Authority
furnishes, or coordinates with LIPA's 


                                      102
<PAGE>

agents, attorneys and consultants to provide, such other services as LIPA may
from time to time request.

      All services rendered under the Administrative Services Agreement will be
at the actual cost thereof, including a reasonable charge for general and
administrative expense. See Note 14 to the Notes to the Financial Statements.

      Immediately prior to the Merger, LILCO made payments of severance, change
of control and other employee benefits to William J. Catacosinos, the former
Chief Executive Officer of LILCO, Joseph W. McDonnell, the former Vice President
of Communications of LILCO, Leonard P. Novello, the former Senior Vice President
and General Counsel of LILCO and twenty-two other former LILCO executives
totaling approximately $67 million which were not disclosed to the Authority at
such time.

      The Authority considered these payments to be in violation of the merger
agreement and related documents, including the MSA and EMA. On June 16, 1998,
the Authority approved a resolution which, among other things, instructed the
Authority and LIPA to (i) withhold and place in escrow present and future
management fees owed to KeySpan and (ii) withhold their consent to the
appointment of William J. Catacosinos, Joseph W. McDonnell and Leonard P.
Novello to senior executive positions at KeySpan.

      On December 15, 1998, the Authority and LIPA, KeySpan and the PSC entered
into an agreement by which KeySpan represented and warranted (i) that Mr.
Catacosinos tendered his retirement and resignation as Chief Executive Officer
and Chairman of the Board of KeySpan effective July 31, 1998; and (ii) that the
24 LILCO executives (other than Catacosinos) who received payments have either
been terminated, retired, resigned or been retained as officers on condition
that all previously paid severance payments be repaid to KeySpan. In addition,
KeySpan agreed to pay to LIPA its cost of providing postage-paid bill return
envelopes to its customers for the next three years which cost is expected to be
$5.4 million. In return, the Authority and LIPA agreed to release and pay to
KeySpan the monies related to the management fees held in escrow by LIPA.

                        ON FINANCIAL STATEMENT SCHEDULE

of Long Island Lighting Company d/b/a LIPA

Our audit of the financial statements referred to in our report dated March 5,
1999 appearing on page 44 of this 1998 Annual Report on Form 10-K also included

financial statement schedule presents fairly, in all material respects, the
information set forth therein when read in conjunction with the related
financial statements.
